3 Punctuation Problems

3 Punctuation Problems 3 Punctuation Problems 3 Punctuation Problems By Mark Nichol In each of the three sentences below, the internal punctuation employed does not support the sentence construction. Discussion below each example explains how to provide sufficient scaffolding. 1. â€Å"Enjoy the break in the weather, a major storm is set to hit Northern California tonight.† This sentence contains a comma splice, it includes two independent clauses separated by a comma, which is insufficient to carry the load. (That sentence also suffers from a comma splice.) When a sentence is constructed like the example or the first sentence in this annotation when it could be divided into two smaller sentences do so, or at least replace the intervening comma with the sturdier semicolon: â€Å"Enjoy the break in the weather; a major storm is set to hit Northern California tonight.† (Alternatively, a colon or an em dash is sometimes appropriate.) 2. â€Å"But one thing is certain, belief in a fair press is gone.† If the first clause in a sentence is a setup for what follows, follow the first clause with a colon; as with the comma splice, the comma is too weak to sustain the transition: â€Å"But one thing is certain: Belief in a fair press is gone.† 3. â€Å"He had two handguns, a Glock 10 mm and a Sig Sauer 9 mm, and a Bushmaster rifle. The context may be clear in this specific sentence, but often, this construction is ambiguous. What appears to be two elements, â€Å"two handguns† and â€Å"a Bushmaster rifle,† interrupted by an interjection that precisely describes the first element, could also be interpreted as five objects described in three elements: â€Å"two handguns,† â€Å"a Glock 10 mm and a Sig Sauer 9 mm,† and â€Å"a Bushmaster rifle.† To eliminate the ambiguity, use parentheses or a pair of em dashes (whichever seems appropriate in the particular case) to set the annotation off from the rest of the sentence: â€Å"He had two handguns a Glock 10 mm and a Sig Sauer 9 mm and a Bushmaster rifle.† Want to improve your English in five minutes a day?

Computers and Marketing Essay Example | Topics and Well Written Essays - 500 words

Computers and Marketing - Essay Example It is inevitable that with most people doing things on-line, marketing and advertising executive are now also going on-line. Internet traffic continues to surge with more people going for convenience, ease and security of transacting their business on-line. Advertisers naturally go where the people are. Discussion Advertising serves a dual purpose: commercial, as when promoting a new product or a new service, and secondly, as a public service (such as broadcasting weather reports). But the essence of advertising has always been primarily commercial in nature. Advertising industry executives always find creative ways to post their ad messages and this is almost everywhere: in newspapers, magazines, giant billboards, moving billboards (such truck-side advertising or even on the bodies of airplanes like the Irish budget airline Ryanair) or in broadcasting such as radio and television. The latest media are digital Web sites on Internet and digital mobile devices such as cellular phones. It seems there is no escaping these ubiquitous advertisements. Like most people of my generation, I spend a considerable time of my waking hours on the Internet.

Patient Satisfaction Compared in 5 Rural and 5 Urban Hospitals in Research Paper

Patient Satisfaction Compared in 5 Rural and 5 Urban Hospitals in Illinois - Research Paper Example Majority concentrates on delivery of primary health care services. As portrayed by recent research, most rural patients’ by-pass rural hospitals to seek medical attention from urban- based hospitals. Due to under utilization of rural hospitals, these hospitals continue facing financial challenges due to reduced occupancy rates and declining government assistance (Dent & Haslam, 2006). The issue of lower occupancy rates has substantially increased costs, hindering efforts to introduce new services and technology. As such, the rural population continue to raise alarm of limited access to quality health care while at the same time they under- utilize rural hospitals leading to their closure The survey conducted in regard to satisfaction derived by patients generally rated the quality of rural care lower than that of urban care. In the figure below, the study was centered on two samples each consisting five hospitals selected from both rural and urban settings. The study found tha t, most patients were satisfied with services rendered by urban hospitals than those offered by their rural counter parts. Many patients from the rural setting either expressed dissatisfaction or were not sure of the quality of local services. Graphs Fig 1.0 Patients response on level of service satisfaction at rural hospitals Source: UnitedHealth Group/Harris Interactive Survey of patient response to quality of services in rural hospitals, May 2011 Results From the research carried out, it was learnt that 15% were strongly satisfied, 33% satisfied, 9% were not sure, 28% dissatisfied while 15% were strongly dissatisfied. Patient’s response on level of service satisfaction at urban hospitals Source: UnitedHealth Group/Harris Interactive Survey of patient response to quality of services in urban hospitals, May 2011 Results From the research undertaken, it was learnt that 37% of all the patients examined were strongly satisfied, 47% satisfied, 5% was not sure, 9% was dissatisfie d while 2% expressed strong dissatisfaction. Discussion Patients perceive rural hospital care to be more personal as they can identify themselves with the caregivers. There may be a chance of caregivers to interact with their patients after discharge. Therefore, they tend to be more attentive and courteous in their job (Chern & Wan, 2000). On the other hand, the anonymity of urban areas endangers the staff attitude of â€Å"who cares,† â€Å"I’ll never see the patient again.† Patients may have lower expectations of rural hospitals when they know that they lack necessary technology or experience high patient to staff ratio. As such, they may evaluate their preferred care against a lower set of expectations. In rural setting, there could be lesser chances of error due to the simpler care processes and simple technology being in use. From the previous studies, it was established that patients discharged from teaching hospitals derived more satisfaction. More so, pa tients want to receive care from hospitals with cutting -edge care, physicians who are the best in their field or those using state of art technology. Perhaps, patients viewed Medicare derived from such modern urban hospitals to be worth the cost associated rather than being prodded and poked by trainees in institutions that train practitioners and conducts research. Patient’s hospital choice between the rural and urban was found to depend on the ability of the patient to evaluate available options and their

Types of Parasites

Types of Parasites Chapter 1 General Introduction 1.0 Introduction 1.1 Fish Parasites Parasitism is an obligatory association between two distinct species, in which one species parasite is dependent on its host for nutrients and shelter (Elmer Glenn, 1961). The parasites can be divided into two groups which are ectoparasites and endoparasites. Ectoparasites are found on the external surfaces of the host such as skin, fins and gills, while endoparasites usually hide within the internal tissues or organs in the host (Cheng, 1986). Fishes acts as hosts to a wide variety of parasites such as the protozoans, platyhelminthes, acanthocephalan, nematodes and crustaceans (Lim, 1987). Parasites are typically smaller than their host. A distinct host usually found to be infected by a group of parasites (Zander, 1998). The chemical and physical factors which are either in micro-environment or macro-environment play an important role to determine the distribution and density of parasites (Cheng, 1986). Parasites show a preference among different age groups (Zander et al., 1993), sex of host (Lim, 1987) or according to host density and behaviour (Cheng, 1986). Remarkably, parasites have a distinguished ability to deal with the normal physiological and structural changes of the host, for example, the peristaltic movement and intestinal mucosa (Cheng, 1986) for survival, and starting their parasitism phase. Apart from that, the presence of parasites commonly irritates the host, causing immunological change (Lim, 1979) and may eventually cause death (Zander, 1998). Parasites penetrate the hosts tissue, causing chronic body system problems to the host. Moreover, the irritation site will initiate secondary infection by micro-organisms to the host (Cheng, 1986). 1.2 Specific parasite Gobies play a role as main host and transmitters (Zander, 1993) of parasites. Varieties of protozoan, helminthes, mollusks, crustaceans have been described as parasites of fish (Lim, 1987). They are able to reproduce either sexually or asexually. Some species of parasites have specific attachment to enable them to hold onto the host for food, transport (Cheng, 1986) or shelter (Elmer Glenn, 1961). The phylum Platyhelminthes consists of a large group of free-living invertebrates but most live as parasitic species on or in other organisms. There are 3 main classes under this phylum, namely, class Monogenea, class Trematode, and class Cestoda (Solomon et al., 2002). Monogeneans are typical gillworms (Bunkley-Williams E. H. Williams, 1994). Some species attach themselves on the body surface or invade into the inner organ of aquatic species (Reed, Francis-Floyd Klinger, 1996). Monogeneans have a series of hooks that enable them to attach on the host (Reed et al., 1996). They usually inhabit the gill and feed on skin mucosa (Lim, 1987). Reed et al. (1996) mentioned that a monogenean, Dactylogyrus sp., usually attaches itself to the gills of freshwater fish. It reproduces by laying eggs, while Gyrodactylus is typically found on the skin and fins of fish. This parasite produces live young or can be described as viviparous during its whole life. Digenea was formerly described as digenetic trematodes and this species of flukes usually has at least two hosts in their life cycle (Smyth, 1962). The parasite usually has a terminal opening mouth with a sucker which is subterminal or ventral. It may or may not have an oral sucker (Yamagutti, 1958). They are particularly found as endoparasites in the digestive tract, but are sometimes found throughout the inner organ systems of vertebrates (Yamagutti, 1958). The adult digeneans are commonly hermaphroditic but reproduction still requires two worms. Digeneans have a complex life cycle with two to three intermediate hosts (Cheng, 1986). Cestode is a parasitic flatworm or commonly known as tapeworm (Solomon, et al., 2002). An adult worm consists of a scolex which maybe armed with suckers and sometimes hooks for attachment on host (Solomon et al., 2002); and a strobila which is a linear series that be formed by one or more segments (also described as proglottides) which contain reproductive structures (Yamagutti, 1959). Most of the cestodes are monoecious and each proglottid has a male reproductive system and a female reproductive system. Both self and cross-fertilization will take place in cestode (Smyth, 1962). Nematode is commonly called as round worm (Solomon et al., 2002) that can infect a vertebrates eye, mouth, alimentary system, body cavity and the other parts (Smyth, 1962). This species can also be found as a parasite of many species of fishes. Some species parasitize plants and are described as an important agricultural pest (Campbell, 2002). It is smooth and consists of a cylindrical body, a pointed tail and cuticle layer surrounding its body (Solomon et al., 2002). Nematodes are typically dioecious. The female is generally larger than the male (Cheng, 1986). Apart from that, nematode life cycles differ depending on the species of the nematode (Smyth, 1962). 1.3 The Family of Gobiidae The members which form the family Gobiidae are known as gobies. It is the largest family of marine fishes and consists of two hundred genera (retrieved from Wikipedia). The members of the Family Gobiidae have their own special characteristics. They have a cylindrical body and the pelvic fins usually form an adhesive disc (Maurice Anthony, 1993). This species usually inhabits the shore in shallow bays and estuaries and also freshwater swamps and lakes (retrieved from Wikipedia). Some species are restricted to coral reefs, rocky coast, sandy, mangrove swamp or muddy beaches (Murdy, 1989). 1.4 Oxudercine Gobies (Mudskippers) The mudskippers are known as ‘ikan belacak, ‘ikan tembakul or ‘ikan belukor in Malay. The members of the goby family classified as mudskipper species based on body traits and behaviours (Murdy, 1989). Oxudercine gobies are described as the members of mudskippers (Murdy, 1989). There are thirty four species from ten genera found throughout the world (Murdy, 1989). They are Apocryptes, Zappa, Pseudapocryptes, Apocryptodon, Parapocryptes, Oxuderces, Scartelaos, Boleophthalmus, Periophthalmodon and Periophthalmus. Only seven genera of mudskippers (Periopthalmodon, Periophthalmus, Boleophthalmus, Scartelaos, Oxuderces, Parapocryptes and Pseudopocryptes) were found along the Selangor coast (Khaironizam, 2004). According to Khaironizam (2004), Cantor (1849) had identified five species of mudskippers while Koumans (1953) had noted eight species in Malaysia. Apart from that, there were four species already reported by Macne (1968) and five species were described by Berry (1972). He also mentioned that Murdy (1989) stated 11 species of mudskippers in Malaysia while Takita (1999) had studied 12 species of mudskippers (refer to Appendix A5). The mudskippers are euryhaline and semi-terrestrial species (Clayton, 1993). They have a rounded body and united pelvic fins. They also have a pair of protruding eyes and one to two rows of teeth in the upper jaws. Besides this, they can survive for a long time above water and move on land. Commonly, the males are smaller than the females. The mudskippers usually feed on crabs, insects, and other small organisms (Clayton, 1993). There are several adaptations that allow the mudskippers to survive successfully out of the water. Their bronchial chamber can fill up with water which allows them to walk on land for up to several hours. They spend much of their lives out of water and are able to undergo osmoregulation as well as oxygen uptake via their skin and gills (Clayton, 1993). They are abundant in muddy areas or mangroves. Oxudercine gobies often build mud towers around their burrows as refuge from predators (Clayton, 1993). The mudskippers have certain economic importance which provide substituted fishery for the period of torrential rain in some coastal countries. These fishes are commonly eaten in China, Taiwan, India and some parts of Malaysia. Nowadays, the mudskippers are also used as feed for aquarium fish (Clayton, 1993) 1.4.1 World Distribution of Mudskippers Mudskippers can be found around the tropical world as well as in the coastal regions of Asia, from Indonesia to Borneo (see 3). A few species are also found in Africa and Australia, whereas none are found in the new world (refer to Appendix A1). 1.5 Literature Reviews on Gobiid Parasites (refer to Appendix A7) There is too few research on parasitological studies of mudskipper in the Asian region. Most of the studies nowadays concentrate on the behavior and ecology of oxudercinae gobies (Khaironizam, 2004); taxonomic and cladistic of the oxudercine gobies (Murdy, 1989); and the nitrogen excretion of mudskipper in water and on land, the growth of mudskipper, habitat of mudskipper and osmoregulation system among this species (Clayton, 1993). Mhaisen and Al-Maliki (1996) mentioned that Myxobolus pfeifferi (Sporozoa), Diplozoon sp. (Monogenea) and Neoechinorhynchus sp. (Acanthocephala) were found in dark-blotched mudskippers, Periophthalmus waltoni, from the mudflats of the Khor Al-Zubair estuary. A new record showed the heterophyid (trematode) had served Boleophthalmus pectinirostris and Scartelaos sp. as second intermediate host (Sohn et al., 2005). Clayton (1993) indicated that cestode, agamofilarial and acanthocephalid cysts have been described as parasite in Periophthalmus koelreuteri (Pearse, 1933), Periphthalmodon schlosseri and Boleophthalmus boddarti (Khoo, 1966). Besides, the larval ascarid nematodes infected Periophthalmodon schlosseri (Khoo, 1966). Pseudapocryptes lanceolatus were found to be infected by parasitic copepod, Gnathia sp. A larval cestode was also described by Pearse (1932) in Periophthalmus modestus. A study by Choudhury and Nandi (1973) did not establish any parasitic infection on Boleophthalmus boddarti and Scartelaos histophorus. The intestinal flagellates were also noted by Pearse (1933) in Boleophthamus boddarti. The bacterial flora had been observed by Morii and Kasama (1989) to be in the intestine of Boleophthalmus pectinirostris and Periophthalmus modestus. In West Africa and Singapore, a new species of acanthocephalan was detected in Periophthalmus barbarus and Periophthalmus schlosseri. Eighteen Gyrodactylus species were collected from gobies of the genus Pomatoschistus and the host-parasite relationship was discussed (Huyse et al., 2003). Geets et al. (1999) found that three gobies (Pomatoschistus minutus, P. lozanoi and P. pictus) were infected by Gyrodactylus arcuatus in the North Sea and noted that Gyrodactylus longidactylus n. sp. is host specific (Geets et al., 1998). This study showed that monogenea was found in Pomatoschistus lozanoi from the North Sea (Geets et al., 1998) Longshaw et al. (2003) discovered that Gyrodactylus quadratidigitus n. sp. (Monogenea: Gyrodactylidae) was found on the on the gills and body surface of Thorogobius ephippiatus (Lowe). Neogobius fluviatilis, Neogobius kessleri and Neogobius melanostomus from Slovakia were investigated by OndraÄ kovà ¡ et al. (2003) and were found to be infected by a metazoan parasite.According to Garcia et al. (2004), Lepidogobius lepidus that has been newly recorded as being a host to thirty three cestode pleroceroides of Phyllobothrium sp. Digenea (Aphalloides timmi, Apatemon gracilis, Podocotyle atomon, Cryptocotyle concavum, Cryptocotyle lingua) and nematode (Hysterothylacium sp.) are found to be present externally and internally in Pomatoschistus minutus, P. pictus, P.microps, Gobiusculus flavescens and Gobius niger (Zander, 2004). Pampoulie et al. (1999) noted that infection of Aphalloà ¯des cÅ“lomicola has a bad impact on Pomatoschistus microps (Krà ¸yer, 1838). Gobies were described as main host and transmitters (Zander, 1993) of parasites. Zander (1998) noted that goby fishes serve the digenean, cestode, nematode and acanthoceplalan serve the goby fishes as their intermediate host. Pomatoschistus microps is the final host of Podocotyle atomon and Aphalloides timmi and these parasites had different abundance according to different seasons (Zander et al., 2002). Malek (2001) mentioned that Labratrema minimus and Cryptocotyle concavum have infected gobies (Pomatoschistus microps and Pomatoschistus minutes). According to Charlebois et al. (1997), there were 144 collected round gobies parasitized by 7 species of parasites. They are Diplostomum sp.(digenean), Eustrongylides tubifex(nematode), Rhabdochona decaturensis, Spinitectus sp., Spiroxys sp.(nematode), Leptorhyncchoides thecatus (class Palaeacanthocephala) and glochidia (larvae of freshwater bivalves). Apart from that, another study showed that four of the 67 gobies had parasites and three of them were infected by Acanthocephalus dirus while the latter was infected by nematode. Parasite infection of the male gobies was higher than female (Appleby, 1996). Most of the parasites were found from the gills, oral cavity and pharynx of gobies. Marianne et al. (2004) mentioned that Ellipsomyxa gobii (Myxozoa) infected goby, Pomatoschistus microps, as fish host. According to Lynda et al. (2004), there were four species of freshwater parasites were found in round goby, Neogobius melanostomus. These parasites included trematodes and crustaceans. Schistocephalus solidus, Aphalloides timmi and Apatemon gracilis including a metacecaria had been found in the goby fishes (Zander, 2001). These gobies have a low richness, prevelance, mean intensity and mean abundance of parasite. The gobies are intermediate host of digenean which is Diplostomum sp., acanthocephala (Acanthocephalus dirus) and nematode, Eustrongylides sp. (Camp et al., 1999). 1.6 Objectives of Study This is a general study on the parasites of oxudercine gobies (mudskippers) along the Selangor coastal area. The study is divided into two parts with the first part being a general survey of parasites on mudskippers while the second part discuss the relative factors affecting distribution of parasites. It also had an observation on the occurrences mudskippers along Selangor coast. Chapter 2 Materials and Methods 2.0 Introduction The present study focuses on the mudskippers found along the coastal area of Selangor. The fishes were caught from Jeram, Sementa (2 sites), Carey Island (3 sites) and Morib. A total of 127 specimens belonging to 7 species of mudskippers were collected and they included Boleophthalmus boddarti, Periophthalmus chrysospilos, Periophthalmus novemradiatus, Periophthalmus modestus, Periophthalmodon schlosseri, Pseudapocryptes elongates (Pseudapocryptes lanceolatus) and Scartelaos histophorus. Fish parts including the body surface, gills and gut were observed. The weight and the size of each specimen (standard size and the length) were recorded. Apart from that, the diet of mudskippers also was documented according to their stomach contents. Next, the parasites found from different parts of fish specimens were identified and tabulated. ANOVA, Coefficient of Dispersion, the Chi Square Test and population parameters were used to analyze data. 2.1 Methodology i) Fish collection site The fish specimens were caught by having the sampling at Jeram, Sementa, Carey Island and Morib (see 4). The field works were carried out during spring tide because the low tide was the lowest level while the high tide had the highest point when compared to the normal time. The salinity and pH of water were recorded. Fishes were caught by using different sizes of scoop net (medium or small). Otherwise, the fish can be caught using the cast net or by angling. Some crustaceans or small fishes were used as bait to attract fishes. The mudskippers were kept in water-filled aquarium to make sure that they may survive longer. (If the fishes die during sampling, some ice cubes can be added into plastic bag to freeze the dead fish). Species identification was done using a taxonomic characteristic key. 2.2 Fish Dissection Each fish was killed by a blow on their head or by severing the nerve cord. The weight and the size of specimen (standard size and the length) were recorded. After that, the gill and alimentary system of the fish were taken out step by step for observations. The parts examined were placed in a petri dish (with some drops of seawater in it. The seawater possibly contained the protozoans, copepods, mud, sea grasses and the others) Gill removal The operculum (a bony plate) was lifted and the gill parts were examined. Next, the operculum was cut across its base and the gill was being exposed. The gills were removed by cutting the upper and lower attachments of the arch. The gill apparatus were separated one by one into 8 pieces and the isolated gills were placed into a petri dish partially-filled with water. A pipette was used to suck and separate the parasite from the mucus, blood blot or tissues. A needle or a pair of fine forceps was usually used to scrape the mucus or tissue so as to separate the parasites from mucus or tissue. Alimentary system or gut part removal The alimentary system is a canal which starts from the esophagus and ends below the rectum. The body of the fish was cut longitudinally from the operculum parts till the tail part of the fish. After getting out the gill apparatus, it was lifted out together with the alimentary system by using a pair of forceps. The alimentary tract was cut into 4 parts (stomach, small intestine, big intestine and rectum). Again, a needle or forceps was used to scrape the mucus or tissue to separate the parasites from the mucus or tissue. The food items from the stomach content of the fish were recorded because this could possibly gives us some informations on the life cycle of parasite (Mhaisen and Al-Maliki, 1996) 2.3 Parasite collection Scalpel or dissecting needles were used to scrape gently the gill filaments and gut dermis of the fish. The parasite were sucked out by using a small pipette (if they were too small) or a pair of forceps (if they were bigger) and placed into a cavity block filled with some drops of seawater. Then, the parasite was examined under a dissecting microscope. The parasite was preserved using different methods according to the species of parasites. i) Fixation of the monogenean or any unknown species of parasite A coverslip was placed over the parasite after it was placed at the centre part of a slide. The slide-fixed parasite would be examined with a dissecting microscope to make sure the slide contained the specimen. After leaving the slide to be dry for a few minutes, a clear nail varnish was used to fix the four edges of the coverslip on the slide to prevent any movement of the coverslip. Ammonium picrate glycerin was added to the sides of the coverslip to allow it to seep under the coverslip, to fix and to clear the specimens. ii) Preservation methods for different types of parasite There were different parasite preservation methods used depending on the species and quantity of the collected parasites (see Table 1) Table 1: Preparation methods for different types of parasite Parasite Preparation methods Nematode Warm 70% alcohol was poured over the worms and later the specimens were transferred to fresh 70% alcohol for storage Trematode Digenea Warm 10% formalin was poured over the worms and the specimens were kept overnight in the fixative. They were transferred into fresh 70% alcohol for storage Cestode Warm 70% alcohol was poured over the worms and later transferred to fresh 70% alcohol for storage 2.4 Data analysis Coefficient of Dispersion (C.D) The coefficient of dispersion (C.D) was calculated to see how the population is dispersed, such as random, uniformed or clumped. It is calculated by dividing the variance over the mean and the relative relationship between mean and variance would establish the distribution pattern of the parasites in a population. If the C.D is close to or equals to one, the population is randomly dispersed. If the C.D is more than one, the population is clumped or over-dispersed. If the C.D is less than one, it shows that the population is uniformly dispersed or under-dispersed. The ratio of the mean to the variance is called the Coefficient of Dispersion (C.D) and the calculated formula is as below: The Analysis of Variance (ANOVA) The Analysis of Variance (ANOVA) (refer to Appendix A4) was used to test for significant differences among the variances. In this study, ANOVA was used to test for significant differences among the variances of parasites in the mudskippers sampled around the Selangor coastal area. In addition, the relative test had exhibited the interaction among the different factors affecting the occurrences and quantity of parasites. A test was calculated to show the correlation between the interaction of the different independent variables and the quantity of parasites on the gills and gut of the mudskipper. The significant result for fish survival in relation to the quantity of different parasite species under different variables was also documented. Chi Square Test The Chi Square Test was done to test whether a sample from a population follows a specified distribution or not. The Chi Square value was calculated as follow: Where as: = The observed number of cases which be written off as i row number of j column number = The expected number of cases which under the H0 to be characterized with i row number of j column number = It is run over all cells r = The number of rows in Chi-square table k = The number of columns in Chi-square table The calculated value was tested at a significance level of 95%. The value was yielded by the formula which was approximated by distribution with (r-1) (c-1). If the calculated value exceeded the tabulated one, the null hypothesis would be rejected at p = 0.05. Population Parameter The basic parasitological parameters which are prevalence, abundance and intensity were calculated for each parasite. According to Cox (1982), prevalence is defined by the percentage of host. Formula calculation of each basic parasitological parameter is as below: Prevalence is to look at how common a host (mudskipper) is infected in a population. Prevalence = Number of infected host X 100% Number of host examined Intensity is the quantity of parasite found in the host samples (mudskippers). Intensity = Total number of parasites Total number of infected host Abundance is the total number of parasites found in all the examined hosts. Abundance = Intensity Total number of host examined Chapter 3 Results and Discussions 3.0 Introduction This study focuses on parasites of oxudercine gobies (mudskippers) along Selangor coast. The fishes were caught (see Chapter 2) from Jeram, Sementa (2 sites), Carey Island (3 sites) and Morib (refer to 4). There were totally 127 mudskippers caught for study. The collected fish were identified by using taxonomic keys and cladistic analysis of family Gobiidae. 127 mudskippers consist of 7 species from 5 genera were collected. They were 27 Boleophthalmus boddarti, 36 Periophthalmus chrysospilos, 54 Periophthalmus novemradiatus, 1 Periophthalmus modestus, 1 Periophthalmodon schlosseri, 7 Pseudapocryptes elongates (Pseudapocryptes lanceolatus) and 1 Scartelaos histophorus (refer Appendix A3). In this study, parasites of the gills, the gut and the body surface of fish were investigated (see Chapter 2). There was found nothing from the body surface of fish. Five groups of parasites found from the whole study. They were monogenean, digenean, nematode, cestode and some unknown parasite cysts. Apart from that, the environmental factors (pH and salinity of water) also were discussed (see Table 2; Appendix A2). 3.1 Parasites of oxudercine gobies (mudskippers) Table 2 showed the summarized parasite data of oxudercine gobies (mudskippers) (refer to Appendix A2). Parasites species differ among oxudercine gobies (mudskippers) based on studied sites. Five groups of parasites were detected from this present study (see Table 3; 5-11). Identification is not easily to be done based on general main beliefs about parasite. There are varies in morphology and biological characters among parasites (see Satyu Yamaguti, 1953). The collected parasite consists of digeneans (see section 1.2; 5-8), monogenean (see section 1.2; 9), nematode (see section 1.2), cestode (see section 1.2; 10), and unidentified parasite cysts (see 11). Digeneans inhabit the gills and the gut of mudskippers (see Table 3). In this study, three types of digeneans were found in the gut of mudskippers. However, two of these three types of digeneans were also found in the gills. These digeneans are probably regurgitated from the gut as they have the same morphology with the guts digeneans. Gyrodactylus sp. (Monogenea, Gyrodactylidae) was described from the gills of mudskippers (see 8). The gills are the preferred part for monogenean. Table 3 showed that cestode and nematode inhabit the gut of fish specimens. Most of them found as encysted form in the mudskippers. In this study, the unidentified parasites cysts were found in the gills and gut of the mudskippers (see Table 3; 11). The unidentified parasites found in the gut of the mudskippers are probably cysts of cestode or nematode. However, some unknown parasites cysts which were found in the gills are considered as myxosporid. Table 2 Excel Table 3: Parasite record of the examined fish Parasite species Number of Species Microhabitat i) Digenea (see 5-8) 3 Gut and gill ii) Monogenea (see 9) 1 Gill iii) Cestode (see 10) 1 Gut iv) Nematode 1 Gut v)Unidentified parasite cysts 3.2 Parasites and their hosts Table 4 showed the presences of parasites on oxudercine gobies (mudskippers). Eight monogeneans were found limited to Pseudapocryptes lanceolatus (see Table 4 Table 5). Monogenean seems to be host specific and it prefers to inhabit the gills of Pseudapocryptes lanceolatus. Next, digeneans occurred in Periophthalmus chrysospilos and Periophthalmus novemradiatus (see table 4). There were 136 digeneans found in Periophthalmus chrysospilos while ten digeneans were detected from Periophthalmus novemradiatus (see Table 5). It is possibly because digeneans are able to adapt well in Periophthalmus chrysospilos. Periophthalmus chrysospilos, Periophthalmus novemradiatus and Periophthalmodon schlosseri were infected by cestodes (see Table 4). Most (twenty eight cestodes) were found in Periophthalmus novemradiatus (see Table 5). According to Table 5, there were twenty five nematodes found from Periophthalmus novemradiatus. Nematodes also occurred in Periophthalmodon schlosseri, mostly in the encysted form in the gut of mudskippers. There were 402 unidentified parasite cysts (see section 3.1) observed in Boleophthalmus boddarti, Periophthalmus modestus and Periophthalmus novemradiatus (see Table 4 Table 5). Most were found in Boleophthalmus boddarti. .

Table 6 showed that site Sementa 2 with salinity reading from 23†° to 25†° and pH of water between 7.35 and 7.58 had the highest parasitic infection rate. There were 29 out of 40 samples found to have parasitic infection. Morib recorded the lowest parasitic infection rate (6%), only one out of 18 mudskippers was infected with parasite cysts. The parasitic infection rate of the mudskippers may perhaps vary with a distinct study area. The abundance of parasite was probably affected by the salinity of the macro-habitat (Zander Reimer, 2002). Monogenean prefers to inhabit in water with pH 7.44 (see Table 7; 13). Digeneans can be found in water with pH ranging from 5.71 to 8.71 (Table 7). Most digeneans were found in water with pH 7.35. Cestode and nematode occurred individually in the inner body of the host. Cestodes were found from the site Carey Island 2, site Sementa 2 and Morib (see Table 2). Table 7 showed that twenty-eight cestodes were found from site Carey Island 2 (see Table 2) with water pH measured as 5.71. Nematodes could be found in water with a wide range of pH ranging from 5.71 to 8.71 (Table 7). With reference to Table 7, the unidentified parasite cysts were found more abundantly in water pH 7.35 (Table 7; 14). The abundance of parasites in a distinct area differs with pH of water based on their own optimum pH and tolerance to the environment.

The parasites can be divided into two groups which are ectoparasites and endoparasites. Ectoparasites are found on the external surfaces of the host such as skin, fins and gills, while endoparasites usually hide within the internal tissues or organs in the host (Cheng, 1986). Fishes acts as hosts to a wide variety of parasites such as the protozoans, platyhelminthes, acanthocephalan, nematodes and crustaceans (Lim, 1987). Parasites are typically smaller than their host. A distinct host usually found to be infected by a group of parasites (Zander, 1998). The chemical and physical factors which are either in micro-environment or macro-environment play an important role to determine the distribution and density of parasites (Cheng, 1986). Parasites show a preference among different age groups (Zander et al., 1993), sex of host (Lim, 1987) or according to host density and behaviour (Cheng, 1986). Remarkably, parasites have a distinguished ability to deal with the normal physiological and structural changes of the host, for example, the peristaltic movement and intestinal mucosa (Cheng, 1986) for survival, and starting their parasitism phase. Apart from that, the presence of parasites commonly irritates the host, causing immunological change (Lim, 1979) and may eventually cause death (Zander, 1998). Parasites penetrate the hosts tissue, causing chronic body system problems to the host. Moreover, the irritation site will initiate secondary infection by micro-organisms to the host (Cheng, 1986). 1.2 Specific parasite Gobies play a role as main host and transmitters (Zander, 1993) of parasites. Varieties of protozoan, helminthes, mollusks, crustaceans have been described as parasites of fish (Lim, 1987). They are able to reproduce either sexually or asexually. Some species of parasites have specific attachment to enable them to hold onto the host for food, transport (Cheng, 1986) or shelter (Elmer Glenn, 1961). The phylum Platyhelminthes consists of a large group of free-living invertebrates but most live as parasitic species on or in other organisms. There are 3 main classes under this phylum, namely, class Monogenea, class Trematode, and class Cestoda (Solomon et al., 2002). Monogeneans are typical gillworms (Bunkley-Williams E. H. Williams, 1994). Some species attach themselves on the body surface or invade into the inner organ of aquatic species (Reed, Francis-Floyd Klinger, 1996). Monogeneans have a series of hooks that enable them to attach on the host (Reed et al., 1996). They usually inhabit the gill and feed on skin mucosa (Lim, 1987). Reed et al. (1996) mentioned that a monogenean, Dactylogyrus sp., usually attaches itself to the gills of freshwater fish. It reproduces by laying eggs, while Gyrodactylus is typically found on the skin and fins of fish. This parasite produces live young or can be described as viviparous during its whole life. Digenea was formerly described as digenetic trematodes and this species of flukes usually has at least two hosts in their life cycle (Smyth, 1962). The parasite usually has a terminal opening mouth with a sucker which is subterminal or ventral. It may or may not have an oral sucker (Yamagutti, 1958). They are particularly found as endoparasites in the digestive tract, but are sometimes found throughout the inner organ systems of vertebrates (Yamagutti, 1958). The adult digeneans are commonly hermaphroditic but reproduction still requires two worms. Digeneans have a complex life cycle with two to three intermediate hosts (Cheng, 1986). Cestode is a parasitic flatworm or commonly known as tapeworm (Solomon, et al., 2002). An adult worm consists of a scolex which maybe armed with suckers and sometimes hooks for attachment on host (Solomon et al., 2002); and a strobila which is a linear series that be formed by one or more segments (also described as proglottides) which contain reproductive structures (Yamagutti, 1959). Most of the cestodes are monoecious and each proglottid has a male reproductive system and a female reproductive system. Both self and cross-fertilization will take place in cestode (Smyth, 1962). Nematode is commonly called as round worm (Solomon et al., 2002) that can infect a vertebrates eye, mouth, alimentary system, body cavity and the other parts (Smyth, 1962). This species can also be found as a parasite of many species of fishes. Some species parasitize plants and are described as an important agricultural pest (Campbell, 2002). It is smooth and consists of a cylindrical body, a pointed tail and cuticle layer surrounding its body (Solomon et al., 2002). Nematodes are typically dioecious. The female is generally larger than the male (Cheng, 1986). Apart from that, nematode life cycles differ depending on the species of the nematode (Smyth, 1962). 1.3 The Family of Gobiidae The members which form the family Gobiidae are known as gobies. It is the largest family of marine fishes and consists of two hundred genera (retrieved from Wikipedia). The members of the Family Gobiidae have their own special characteristics. They have a cylindrical body and the pelvic fins usually form an adhesive disc (Maurice Anthony, 1993). This species usually inhabits the shore in shallow bays and estuaries and also freshwater swamps and lakes (retrieved from Wikipedia). Some species are restricted to coral reefs, rocky coast, sandy, mangrove swamp or muddy beaches (Murdy, 1989). 1.4 Oxudercine Gobies (Mudskippers) The mudskippers are known as ‘ikan belacak, ‘ikan tembakul or ‘ikan belukor in Malay. The members of the goby family classified as mudskipper species based on body traits and behaviours (Murdy, 1989). Oxudercine gobies are described as the members of mudskippers (Murdy, 1989). There are thirty four species from ten genera found throughout the world (Murdy, 1989). They are Apocryptes, Zappa, Pseudapocryptes, Apocryptodon, Parapocryptes, Oxuderces, Scartelaos, Boleophthalmus, Periophthalmodon and Periophthalmus. Only seven genera of mudskippers (Periopthalmodon, Periophthalmus, Boleophthalmus, Scartelaos, Oxuderces, Parapocryptes and Pseudopocryptes) were found along the Selangor coast (Khaironizam, 2004). According to Khaironizam (2004), Cantor (1849) had identified five species of mudskippers while Koumans (1953) had noted eight species in Malaysia. Apart from that, there were four species already reported by Macne (1968) and five species were described by Berry (1972). He also mentioned that Murdy (1989) stated 11 species of mudskippers in Malaysia while Takita (1999) had studied 12 species of mudskippers (refer to Appendix A5). The mudskippers are euryhaline and semi-terrestrial species (Clayton, 1993). They have a rounded body and united pelvic fins. They also have a pair of protruding eyes and one to two rows of teeth in the upper jaws. Besides this, they can survive for a long time above water and move on land. Commonly, the males are smaller than the females. The mudskippers usually feed on crabs, insects, and other small organisms (Clayton, 1993). There are several adaptations that allow the mudskippers to survive successfully out of the water. Their bronchial chamber can fill up with water which allows them to walk on land for up to several hours. They spend much of their lives out of water and are able to undergo osmoregulation as well as oxygen uptake via their skin and gills (Clayton, 1993). They are abundant in muddy areas or mangroves. Oxudercine gobies often build mud towers around their burrows as refuge from predators (Clayton, 1993). The mudskippers have certain economic importance which provide substituted fishery for the period of torrential rain in some coastal countries. These fishes are commonly eaten in China, Taiwan, India and some parts of Malaysia. Nowadays, the mudskippers are also used as feed for aquarium fish (Clayton, 1993) 1.4.1 World Distribution of Mudskippers Mudskippers can be found around the tropical world as well as in the coastal regions of Asia, from Indonesia to Borneo (see 3). A few species are also found in Africa and Australia, whereas none are found in the new world (refer to Appendix A1). 1.5 Literature Reviews on Gobiid Parasites (refer to Appendix A7) There is too few research on parasitological studies of mudskipper in the Asian region. Most of the studies nowadays concentrate on the behavior and ecology of oxudercinae gobies (Khaironizam, 2004); taxonomic and cladistic of the oxudercine gobies (Murdy, 1989); and the nitrogen excretion of mudskipper in water and on land, the growth of mudskipper, habitat of mudskipper and osmoregulation system among this species (Clayton, 1993). Mhaisen and Al-Maliki (1996) mentioned that Myxobolus pfeifferi (Sporozoa), Diplozoon sp. (Monogenea) and Neoechinorhynchus sp. (Acanthocephala) were found in dark-blotched mudskippers, Periophthalmus waltoni, from the mudflats of the Khor Al-Zubair estuary. A new record showed the heterophyid (trematode) had served Boleophthalmus pectinirostris and Scartelaos sp. as second intermediate host (Sohn et al., 2005). Clayton (1993) indicated that cestode, agamofilarial and acanthocephalid cysts have been described as parasite in Periophthalmus koelreuteri (Pearse, 1933), Periphthalmodon schlosseri and Boleophthalmus boddarti (Khoo, 1966). Besides, the larval ascarid nematodes infected Periophthalmodon schlosseri (Khoo, 1966). Pseudapocryptes lanceolatus were found to be infected by parasitic copepod, Gnathia sp. A larval cestode was also described by Pearse (1932) in Periophthalmus modestus. A study by Choudhury and Nandi (1973) did not establish any parasitic infection on Boleophthalmus boddarti and Scartelaos histophorus. The intestinal flagellates were also noted by Pearse (1933) in Boleophthamus boddarti. The bacterial flora had been observed by Morii and Kasama (1989) to be in the intestine of Boleophthalmus pectinirostris and Periophthalmus modestus. In West Africa and Singapore, a new species of acanthocephalan was detected in Periophthalmus barbarus and Periophthalmus schlosseri. Eighteen Gyrodactylus species were collected from gobies of the genus Pomatoschistus and the host-parasite relationship was discussed (Huyse et al., 2003). Geets et al. (1999) found that three gobies (Pomatoschistus minutus, P. lozanoi and P. pictus) were infected by Gyrodactylus arcuatus in the North Sea and noted that Gyrodactylus longidactylus n. sp. is host specific (Geets et al., 1998). This study showed that monogenea was found in Pomatoschistus lozanoi from the North Sea (Geets et al., 1998) Longshaw et al. (2003) discovered that Gyrodactylus quadratidigitus n. sp. (Monogenea: Gyrodactylidae) was found on the on the gills and body surface of Thorogobius ephippiatus (Lowe). Neogobius fluviatilis, Neogobius kessleri and Neogobius melanostomus from Slovakia were investigated by OndraÄ kovà ¡ et al. (2003) and were found to be infected by a metazoan parasite.According to Garcia et al. (2004), Lepidogobius lepidus that has been newly recorded as being a host to thirty three cestode pleroceroides of Phyllobothrium sp. Digenea (Aphalloides timmi, Apatemon gracilis, Podocotyle atomon, Cryptocotyle concavum, Cryptocotyle lingua) and nematode (Hysterothylacium sp.) are found to be present externally and internally in Pomatoschistus minutus, P. pictus, P.microps, Gobiusculus flavescens and Gobius niger (Zander, 2004). Pampoulie et al. (1999) noted that infection of Aphalloà ¯des cÅ“lomicola has a bad impact on Pomatoschistus microps (Krà ¸yer, 1838). Gobies were described as main host and transmitters (Zander, 1993) of parasites. Zander (1998) noted that goby fishes serve the digenean, cestode, nematode and acanthoceplalan serve the goby fishes as their intermediate host. Pomatoschistus microps is the final host of Podocotyle atomon and Aphalloides timmi and these parasites had different abundance according to different seasons (Zander et al., 2002). Malek (2001) mentioned that Labratrema minimus and Cryptocotyle concavum have infected gobies (Pomatoschistus microps and Pomatoschistus minutes). According to Charlebois et al. (1997), there were 144 collected round gobies parasitized by 7 species of parasites. They are Diplostomum sp.(digenean), Eustrongylides tubifex(nematode), Rhabdochona decaturensis, Spinitectus sp., Spiroxys sp.(nematode), Leptorhyncchoides thecatus (class Palaeacanthocephala) and glochidia (larvae of freshwater bivalves). Apart from that, another study showed that four of the 67 gobies had parasites and three of them were infected by Acanthocephalus dirus while the latter was infected by nematode. Parasite infection of the male gobies was higher than female (Appleby, 1996). Most of the parasites were found from the gills, oral cavity and pharynx of gobies. Marianne et al. (2004) mentioned that Ellipsomyxa gobii (Myxozoa) infected goby, Pomatoschistus microps, as fish host. According to Lynda et al. (2004), there were four species of freshwater parasites were found in round goby, Neogobius melanostomus. These parasites included trematodes and crustaceans. Schistocephalus solidus, Aphalloides timmi and Apatemon gracilis including a metacecaria had been found in the goby fishes (Zander, 2001). These gobies have a low richness, prevelance, mean intensity and mean abundance of parasite. The gobies are intermediate host of digenean which is Diplostomum sp., acanthocephala (Acanthocephalus dirus) and nematode, Eustrongylides sp. (Camp et al., 1999). 1.6 Objectives of Study This is a general study on the parasites of oxudercine gobies (mudskippers) along the Selangor coastal area. The study is divided into two parts with the first part being a general survey of parasites on mudskippers while the second part discuss the relative factors affecting distribution of parasites. It also had an observation on the occurrences mudskippers along Selangor coast. Chapter 2 Materials and Methods 2.0 Introduction The present study focuses on the mudskippers found along the coastal area of Selangor. The fishes were caught from Jeram, Sementa (2 sites), Carey Island (3 sites) and Morib. A total of 127 specimens belonging to 7 species of mudskippers were collected and they included Boleophthalmus boddarti, Periophthalmus chrysospilos, Periophthalmus novemradiatus, Periophthalmus modestus, Periophthalmodon schlosseri, Pseudapocryptes elongates (Pseudapocryptes lanceolatus) and Scartelaos histophorus. Fish parts including the body surface, gills and gut were observed. The weight and the size of each specimen (standard size and the length) were recorded. Apart from that, the diet of mudskippers also was documented according to their stomach contents. Next, the parasites found from different parts of fish specimens were identified and tabulated. ANOVA, Coefficient of Dispersion, the Chi Square Test and population parameters were used to analyze data. 2.1 Methodology i) Fish collection site The fish specimens were caught by having the sampling at Jeram, Sementa, Carey Island and Morib (see 4). The field works were carried out during spring tide because the low tide was the lowest level while the high tide had the highest point when compared to the normal time. The salinity and pH of water were recorded. Fishes were caught by using different sizes of scoop net (medium or small). Otherwise, the fish can be caught using the cast net or by angling. Some crustaceans or small fishes were used as bait to attract fishes. The mudskippers were kept in water-filled aquarium to make sure that they may survive longer. (If the fishes die during sampling, some ice cubes can be added into plastic bag to freeze the dead fish). Species identification was done using a taxonomic characteristic key. 2.2 Fish Dissection Each fish was killed by a blow on their head or by severing the nerve cord. The weight and the size of specimen (standard size and the length) were recorded. After that, the gill and alimentary system of the fish were taken out step by step for observations. The parts examined were placed in a petri dish (with some drops of seawater in it. The seawater possibly contained the protozoans, copepods, mud, sea grasses and the others) Gill removal The operculum (a bony plate) was lifted and the gill parts were examined. Next, the operculum was cut across its base and the gill was being exposed. The gills were removed by cutting the upper and lower attachments of the arch. The gill apparatus were separated one by one into 8 pieces and the isolated gills were placed into a petri dish partially-filled with water. A pipette was used to suck and separate the parasite from the mucus, blood blot or tissues. A needle or a pair of fine forceps was usually used to scrape the mucus or tissue so as to separate the parasites from mucus or tissue. Alimentary system or gut part removal The alimentary system is a canal which starts from the esophagus and ends below the rectum. The body of the fish was cut longitudinally from the operculum parts till the tail part of the fish. After getting out the gill apparatus, it was lifted out together with the alimentary system by using a pair of forceps. The alimentary tract was cut into 4 parts (stomach, small intestine, big intestine and rectum). Again, a needle or forceps was used to scrape the mucus or tissue to separate the parasites from the mucus or tissue. The food items from the stomach content of the fish were recorded because this could possibly gives us some informations on the life cycle of parasite (Mhaisen and Al-Maliki, 1996) 2.3 Parasite collection Scalpel or dissecting needles were used to scrape gently the gill filaments and gut dermis of the fish. The parasite were sucked out by using a small pipette (if they were too small) or a pair of forceps (if they were bigger) and placed into a cavity block filled with some drops of seawater. Then, the parasite was examined under a dissecting microscope. The parasite was preserved using different methods according to the species of parasites. i) Fixation of the monogenean or any unknown species of parasite A coverslip was placed over the parasite after it was placed at the centre part of a slide. The slide-fixed parasite would be examined with a dissecting microscope to make sure the slide contained the specimen. After leaving the slide to be dry for a few minutes, a clear nail varnish was used to fix the four edges of the coverslip on the slide to prevent any movement of the coverslip. Ammonium picrate glycerin was added to the sides of the coverslip to allow it to seep under the coverslip, to fix and to clear the specimens. ii) Preservation methods for different types of parasite There were different parasite preservation methods used depending on the species and quantity of the collected parasites (see Table 1) Table 1: Preparation methods for different types of parasite Parasite Preparation methods Nematode Warm 70% alcohol was poured over the worms and later the specimens were transferred to fresh 70% alcohol for storage Trematode Digenea Warm 10% formalin was poured over the worms and the specimens were kept overnight in the fixative. They were transferred into fresh 70% alcohol for storage Cestode Warm 70% alcohol was poured over the worms and later transferred to fresh 70% alcohol for storage 2.4 Data analysis Coefficient of Dispersion (C.D) The coefficient of dispersion (C.D) was calculated to see how the population is dispersed, such as random, uniformed or clumped. It is calculated by dividing the variance over the mean and the relative relationship between mean and variance would establish the distribution pattern of the parasites in a population. If the C.D is close to or equals to one, the population is randomly dispersed. If the C.D is more than one, the population is clumped or over-dispersed. If the C.D is less than one, it shows that the population is uniformly dispersed or under-dispersed. The ratio of the mean to the variance is called the Coefficient of Dispersion (C.D) and the calculated formula is as below: The Analysis of Variance (ANOVA) The Analysis of Variance (ANOVA) (refer to Appendix A4) was used to test for significant differences among the variances. In this study, ANOVA was used to test for significant differences among the variances of parasites in the mudskippers sampled around the Selangor coastal area. In addition, the relative test had exhibited the interaction among the different factors affecting the occurrences and quantity of parasites. A test was calculated to show the correlation between the interaction of the different independent variables and the quantity of parasites on the gills and gut of the mudskipper. The significant result for fish survival in relation to the quantity of different parasite species under different variables was also documented. Chi Square Test The Chi Square Test was done to test whether a sample from a population follows a specified distribution or not. The Chi Square value was calculated as follow: Where as: = The observed number of cases which be written off as i row number of j column number = The expected number of cases which under the H0 to be characterized with i row number of j column number = It is run over all cells r = The number of rows in Chi-square table k = The number of columns in Chi-square table The calculated value was tested at a significance level of 95%. The value was yielded by the formula which was approximated by distribution with (r-1) (c-1). If the calculated value exceeded the tabulated one, the null hypothesis would be rejected at p = 0.05. Population Parameter The basic parasitological parameters which are prevalence, abundance and intensity were calculated for each parasite. According to Cox (1982), prevalence is defined by the percentage of host. Formula calculation of each basic parasitological parameter is as below: Prevalence is to look at how common a host (mudskipper) is infected in a population. Prevalence = Number of infected host X 100% Number of host examined Intensity is the quantity of parasite found in the host samples (mudskippers). Intensity = Total number of parasites Total number of infected host Abundance is the total number of parasites found in all the examined hosts. Abundance = Intensity Total number of host examined Chapter 3 Results and Discussions 3.0 Introduction This study focuses on parasites of oxudercine gobies (mudskippers) along Selangor coast. The fishes were caught (see Chapter 2) from Jeram, Sementa (2 sites), Carey Island (3 sites) and Morib (refer to 4). There were totally 127 mudskippers caught for study. The collected fish were identified by using taxonomic keys and cladistic analysis of family Gobiidae. 127 mudskippers consist of 7 species from 5 genera were collected. They were 27 Boleophthalmus boddarti, 36 Periophthalmus chrysospilos, 54 Periophthalmus novemradiatus, 1 Periophthalmus modestus, 1 Periophthalmodon schlosseri, 7 Pseudapocryptes elongates (Pseudapocryptes lanceolatus) and 1 Scartelaos histophorus (refer Appendix A3). In this study, parasites of the gills, the gut and the body surface of fish were investigated (see Chapter 2). There was found nothing from the body surface of fish. Five groups of parasites found from the whole study. They were monogenean, digenean, nematode, cestode and some unknown parasite cysts. Apart from that, the environmental factors (pH and salinity of water) also were discussed (see Table 2; Appendix A2). 3.1 Parasites of oxudercine gobies (mudskippers) Table 2 showed the summarized parasite data of oxudercine gobies (mudskippers) (refer to Appendix A2). Parasites species differ among oxudercine gobies (mudskippers) based on studied sites. Five groups of parasites were detected from this present study (see Table 3; 5-11). Identification is not easily to be done based on general main beliefs about parasite. There are varies in morphology and biological characters among parasites (see Satyu Yamaguti, 1953). The collected parasite consists of digeneans (see section 1.2; 5-8), monogenean (see section 1.2; 9), nematode (see section 1.2), cestode (see section 1.2; 10), and unidentified parasite cysts (see 11). Digeneans inhabit the gills and the gut of mudskippers (see Table 3). In this study, three types of digeneans were found in the gut of mudskippers. However, two of these three types of digeneans were also found in the gills. These digeneans are probably regurgitated from the gut as they have the same morphology with the guts digeneans. Gyrodactylus sp. (Monogenea, Gyrodactylidae) was described from the gills of mudskippers (see 8). The gills are the preferred part for monogenean. Table 3 showed that cestode and nematode inhabit the gut of fish specimens. Most of them found as encysted form in the mudskippers. In this study, the unidentified parasites cysts were found in the gills and gut of the mudskippers (see Table 3; 11). The unidentified parasites found in the gut of the mudskippers are probably cysts of cestode or nematode. However, some unknown parasites cysts which were found in the gills are considered as myxosporid. Table 2 Excel Table 3: Parasite record of the examined fish Parasite species Number of Species Microhabitat i) Digenea (see 5-8) 3 Gut and gill ii) Monogenea (see 9) 1 Gill iii) Cestode (see 10) 1 Gut iv) Nematode 1 Gut v)Unidentified parasite cysts 3.2 Parasites and their hosts Table 4 showed the presences of parasites on oxudercine gobies (mudskippers). Eight monogeneans were found limited to Pseudapocryptes lanceolatus (see Table 4 Table 5). Monogenean seems to be host specific and it prefers to inhabit the gills of Pseudapocryptes lanceolatus. Next, digeneans occurred in Periophthalmus chrysospilos and Periophthalmus novemradiatus (see table 4). There were 136 digeneans found in Periophthalmus chrysospilos while ten digeneans were detected from Periophthalmus novemradiatus (see Table 5). It is possibly because digeneans are able to adapt well in Periophthalmus chrysospilos. Periophthalmus chrysospilos, Periophthalmus novemradiatus and Periophthalmodon schlosseri were infected by cestodes (see Table 4). Most (twenty eight cestodes) were found in Periophthalmus novemradiatus (see Table 5). According to Table 5, there were twenty five nematodes found from Periophthalmus novemradiatus. Nematodes also occurred in Periophthalmodon schlosseri, mostly in the encysted form in the gut of mudskippers. There were 402 unidentified parasite cysts (see section 3.1) observed in Boleophthalmus boddarti, Periophthalmus modestus and Periophthalmus novemradiatus (see Table 4 Table 5). Most were found in Boleophthalmus boddarti. .

Table 6 showed that site Sementa 2 with salinity reading from 23†° to 25†° and pH of water between 7.35 and 7.58 had the highest parasitic infection rate. There were 29 out of 40 samples found to have parasitic infection. Morib recorded the lowest parasitic infection rate (6%), only one out of 18 mudskippers was infected with parasite cysts. The parasitic infection rate of the mudskippers may perhaps vary with a distinct study area. The abundance of parasite was probably affected by the salinity of the macro-habitat (Zander Reimer, 2002). Monogenean prefers to inhabit in water with pH 7.44 (see Table 7; 13). Digeneans can be found in water with pH ranging from 5.71 to 8.71 (Table 7). Most digeneans were found in water with pH 7.35. Cestode and nematode occurred individually in the inner body of the host. Cestodes were found from the site Carey Island 2, site Sementa 2 and Morib (see Table 2). Table 7 showed that twenty-eight cestodes were found from site Carey Island 2 (see Table 2) with water pH measured as 5.71. Nematodes could be found in water with a wide range of pH ranging from 5.71 to 8.71 (Table 7). With reference to Table 7, the unidentified parasite cysts were found more abundantly in water pH 7.35 (Table 7; 14). The abundance of parasites in a distinct area differs with pH of water based on their own optimum pH and tolerance to the environment.

Nickel and Dimed by Barbara Ehrenreich :: Selling in Minnesota

The chapter, Selling in Minnesota, had some disturbing information about the low wage life. As I read, I learned that every place the author went to apply, such as a Wal-Mart and a Home Depot type place called Menards, required the applicant to pass a drug test. The author went out and had to buy detox for $30, but can be up to $60. Also, I learn that 81% of employers do drug test their future employees. I don’t like this statistic, in part because I tried getting a job at Marshall Field’s restaurant and they required me to pass a drug test. Luckily, another employer called me before my scheduled drug screening (which I had planned on passing by being really sneaky and using the urine of a friend of mine), so I took that job offer and everything worked out well. The reason I don’t agree with the drug testing required to access most entry-level jobs, is because the only drugs they actually test for is Marijuana. Cocaine and heroine leave the body within three days, and other drugs aren’t even tested for. So that leaves the most commonly used illicit drug, and one that has the least affect on the user, to be tested for.   Ã‚  Ã‚  Ã‚  Ã‚  When the author first moved to Minnesota, she lived in a friend of a friend’s apartment until she could find another apartment. The friend is out of town and required that the author takes care of her canary in order for her to stay there. The bird, which the author comes to call Budgie, is really annoying and has to be let out of its cage a few times or otherwise it will go crazy in the cage. The author looks extremely had to find an apartment to stay at. Apparently, there is only a less than 1% apartment vacancy in Minnesota. Also, the only apartments that are available are defiantly not accessible to entry-level employees, offering hot tubs and over $1000 a month payments.   Ã‚  Ã‚  Ã‚  Ã‚  One of the places that the author tried to get a job at required that the employee had lived in Minnesota for at least one year.

The purpose of an SCR is to: ? ‘Establish whether there are lessons to be learned from the case about the way in which local professionals and organisations work together to safeguard and promote the welfare of children Identify clearly what those lessons are, how they will be acted upon, and what is expected to change as a result and As a consequence, improve inter-agency working and better safeguard and promote the welfare of children’ Working Together to Safeguard Children (2006), Serious case reviews are not inquiries into how a child died or who is culpable; these are matters for coroners and the criminal courts, respectively The purpose of a Serious Case Review is to:   * â€Å"establish whether there are lessons to be learnt from the case about the way in which local professionals and organisations work together to safeguard and promote the welfare of children   * identify clearly what those lessons are both within and between agencies, how and within what timescales they will be acted on, and what is expected to change as a result; and   * improve intra- and inter-agency working and better safeguard and promote the welfare of children† Who undertakes a Serious Case Review? Regulation 5 of the Local Safeguarding Children Boards Regulations 20069requires Local Safeguarding Children Boards (LSCBs) to undertake reviews of serious cases . LSCBs are inter-agency forums, set up by a local authority, to agree how different agencies and professionals should co-operate to safeguard children. In cases that do not meet the criteria for a full serious case review, theWorking together  guidance suggests conducting individual management reviews or a smaller-scale audit of individual cases . In cases that do meet the criteria, the LSCB establishes a Serious Case Review Panel involving local authority children’s care, health services, education and the police at a minimum as well as any other relevant agencies . The decision to conduct a SCR must be made within one month of the LSCB chair being made aware of the incident and should be completed within six months, unless an alternative timescale is agreed with the relevant Government Office . What happens during a Serious Case Review? Working together to safeguard children  (HM Government, 2010)  states that each of the relevant services identified in the initial scoping of the review is required to undertake an individual management review of its involvement with the child and the child’s family . The aim of an individual management reviews is for an agency to critically assess practices, and identify how any improvements can be made . The SCR Panel will commission an independent overview report, which brings together and analyses findings from all of the individual management reviews and makes recommendations for future action . The SCR Panel should ensure that all contributing organisations and individuals are satisfied that their information is fully and fairly represented and that any findings from other relevant processes such as care or criminal proceedings, an inquest or inquiry/investigation are incorporated into the overview report . The SCR Sub-Committee will also need to look at how the child (where the review does not involve a death), surviving siblings, parents or other family members should contribute to the review and who should facilitate their involvement What happens after a Serious Case Review? Working together to safeguard children  (HM Government, 2010)  states that the SCR Panel should translate recommendations into an action plan and the senior manager in each of the organisations which will be involved in implementing the action plan should sign up to this plan . A copy of the summary which accurately reflects the full overview report must be made publicly available . The summary and key findings must be disseminated to relevant interested parties, and feedback given to the child (if surviving) and family members/carers. Relevant staff must also be given feedback and debriefed . Anonymised copies of the individual management reports, overview report, executive summary, multi-agency action plan, and chronologies must be sent to Ofsted, the relevant Government Office . LSCBs should monitor and audit actions of agencies against action plan – â€Å"at least as much effort should be spent on implementing the recommendations as on conducting the review† Duty to conduct Section 47 (s47) Enquiries Where a child is suspected to be suffering, or likely to suffer, significant harm, the local authority is required under s47 of the Children Act 1989 to make enquiries, to enable it to decide whether it should take any action to safeguard and promote the welfare of the child. Responsibility for undertaking s47 enquiries lies with the local authority in whose area the child lives or is found. ‘Found' means the physical location where the child suffers the incident of harm or neglect (or is identified to be at risk of harm or neglect), e. g. ay nursery or school, boarding school, hospital, one-off event such as a fairground, holiday home or outing or where a privately fostered or looked after child is living with their carers. Whenever a child is harmed or concerns are raised that a child may be at risk of harm or neglect, the authority where the incident occurred is responsible for informing the child's home authority immediately and inviting them to participate in the strategy meeting / discussion to plan action to protect the child. Only once agreement is reached about who will take responsibility is the host authority relieved of the responsibility to take emergency and ongoing action. Such acceptance should occur as soon as possible and should be confirmed in writing. Section 47 Enquiries A s47 enquiry must always be commenced immediately when: There is reasonable cause to suspect that a child is suffering or likely to suffer significant harm in the form of physical, sexual, emotional abuse or neglect; * An Emergency Protection Order or use of police powers of protection have been used. (Further information about legal responsibilities in Appendix 6: Legal Matters) The threshold criteria for a s47 enquiry may be ide ntified during an initial assessment, but may also be apparent at the point of referral, during the interagency checks and information gathering stage, or during a core assessment. 3. 6 (CCLD Unit 2 – Support policies and practice to safeguard children and ensure their inclusion and well being). 3. 7 †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 3. 8 †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 3. 9 †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. .

Broken Globe Stage 2 Essay

Characterization is the process by which authors make characters come alive for readers. Authors have many techniques available to portray characters, and they can broadly be divided into indirect and direct presentation. In the short story â€Å"The Broken Globe†, author Henry Kreisel brillantly develops the two principle characters, Nick Solchuk and his father, through indirect presentation. Consistency is the key to good characterization. From ? rst person point of view, the reader obtains a full portrait of both Nick and his father indirectly by learning what the narrator sees and hears somewhat objectively. Nick, the narrator’s friend, is a successful geophysicist studying the curvature of the earth. He demonstrates persistance, passion, and determination in the study of the earth. He asks the narrator â€Å"eagerly† with â€Å"his face reddening† about his paper to the International Congress. Even under the torture of his father, he still keeps his goal of proving that the earth moves. He even retorts his father by saying â€Å"You can beat me and break my globe, but you cannot stop [the earth] from moving. † This passage shows his determination in his belief. On the other hand, Nick’s father adopts personas of sophistication during the short visit of the narrator. His father is stubborn that he only believes what he sees is the truth: â€Å"[the earth] is ? at, and she stands still. † He is also imptuous and fractious that he â€Å"[beats] Nick like he is the devil† when he wants Nick to accept the same concept of the earth as he believes. Both characters are consistent and static, for they are still living in their own world: one lives in a ? at world and the other lives in the world of science. Another signi? cant objective of characterization is to reveal motivation. Kreisel’s story is set mainly in Alberta, a â€Å"land ? attens until there seemed nothing. † Living in Alberta, Nick’s father sees only the open prairies and ? elds every day; thus he perceives that the earth is exactly ? at and still as what he sees. Moreover, the reader learns that he is hard to change his mind because â€Å"he received an education of sorts when he was a boy. † Therefore, he believes that the earth is the center of the universe and the center is still. Similarly, Nick’s motivation is intrigued by a teacher who teaches him the earth is round and is moving. This teacher’s â€Å"enthusiasm [is] infectious† as Nick says. The teacher shows Nick a world larger than the ?at prairies, a world that is exuberent. Although the two characters’ own views of the world contradict one another, they do care and love each other. To build characters that convincing, the author must make their actions realistic and believable. Nick and his father are plausible due to their backgrounds. Nick’s father is taught that â€Å"the earth is ? at and still,† and what he sees outside in Alberta is only the far-distant prairies with â€Å"neither hill nor tree nor bush. † Furthermore, Nick, suffering from the violence of his father, always illustrates indomitable perserverence in seeking the truth. He continually shows to his father a globe can move, even though he knows his father will be mad. People with bond ? de determination can achieve their goals, just like Nick achieves his goal and becomes a geophysicist (to prove his father wrong? ). Altogether, they both are rounded characters in that they demonstrate many attributes and traits. Nick’s father is a stubborn, impulsive, and fractious father whereas Nick is a passionate, indomitable, and persistent geophysicist. In the story â€Å"The Broke Globe† Henry Kreisel effectively utilizes many techniques to develop characters, and further reveals a thoughtful insight into life. Nick’s father who insistently believes that the world is ? at and still lives in his own â€Å"broken globe†, where â€Å"Satan has taken over all the world† but him. 1. Sample Task for English 12 Writing Prepared by Seaquam Page 15 Characterization: A Father and a Son, How the Apple Falls Characters can make a short story rich and worth reading. In Henry Kreisel’s â€Å"The Broke Globe† the differences in ethics between a man and his father is seen through the eyes of a somewhat neutral narrator. Nick Solchuk is a brilliant man of science, while his father is the polar opposite. His father is a pious prairie farmer who does not value higher education or the values its teaches. Even though these characters are presented indirectly, Kreisel utilizes other methods to develop the characters. He shows them as static and round characters who are plausible and who remain consistent. Being ? rst person narrative, no direct presentation is used because the author cannot speak directly. He simply assumes the persona of a a narrator and therefore all presentation is indirect. One can ? nd out a lot about a character by what others say about him. Nick’s father is developed in the beginning during the conversation between Nick and the narrator. At this point the reader discovers that Nick and his father differ in many ways. Obviously, Nick is a man of great intelligence as the narrator say, â€Å"he studied at Cambridge and got his doctorate there and was now doing research at the Imperial College. † The reader also learns that despite being a brilliant man, nick whistfully remembers his simple childhood growing up in Three Bear Hills, Alberta. Nick’s father is developed much the same way later on in the conversation. Nick reveals that his father is a polar opposite. Nick’s father is shown as a religious prairie farmer with â€Å"a strange imagination. † Nick also explains why there is tension between himself and his father. â€Å"Curious man my father. He had strange ideas and a strange imagination too. He couldn’t understand why I was going to school or university. † â€Å"I suddenly realized that the shape of the world he lived in had O been O ? xed for him by some medieval priest in the small Ukranian villiage he was born in O But he still lived in the universe of the medieval church. : The reader now knows that Nick and his father are very different. Dialogue becomes a very important part of this story. The reader learns a lot about the father by what he says and by what he says he does. The ? rst meeting between the father and the narrator shows a lot about the father. â€Å"You friend of NickOWhat he do now? O still tampering with the earth? † Now, it has been con? rmed that Nick’s ideas differ greatly from his father’s. Nick’s father may be a simple prairie farmer, but that does not mean that he is rude. The father acts very formally when inviting the narrator inside his house. He stands as the narrator comes in, which is a sign of respect; he even brings out coffee for the narrator. The reader continues to learn about the relationship Nick’s father has with his son, and certain other people. The father explains how he exploded at a teacher for â€Å"letting Satan in† and for teaching Nick science at school. This act shows how the father deals with other people. The father goes on to elaborate on how he dealt with Nick as a child. â€Å"I grab him by the arm and I shake him and I beat him like he was the devilOAnd he made me madder and madder because he doesn’t cry or shout or nothing. † â€Å"I would of killed him right there for sure. † The reader now knows how he handles his son. Nick and his father are both static, round characters. They do not change at the end of the story, but they have many traits. Nick’s father proves he does not change by saying to the narrator â€Å"Satan has taken over all the world. † Then he suddenly rousled himself and hits the table with his ? st crying passionately, â€Å"But not me! Not me! † The characters act consistently throughout the story. â€Å"The Broken Globe† is a deeply driven character story. Both main characters are well developed. In some cases, the apple falls very far from the tree.

Just-In-Time Production Essays - Manufacturing, Free Essays

Just-In-Time Production Essays - Manufacturing, Free Essays Just-In-Time Production Just-in-time production is considered to be on the leading edge of technological advancement. With improvements in the virtually every industry, maintaining an effective production line while minimizing inventory costs is a very feasible option. Just-in-time systems are designed to keep inventory costs at a minimum, unlike the ways of old, with large warehouses loaded with back inventory. With technology allowing instantaneous communication around the world, production lines and stores do not have to wait for days for inventory delivery. It can happen, well, just-in-time. Many companies are on the verge of switching to a just-in-time inventory system, to compliment the millions of companies that have already implemented the system. It is generally recognized that effective implementation of just-in-time will result in a significant reduction of inventories. As a matter of fact, inventory levels are key indicators for measuring just-in-time performance (Harrison). The just-in-time philosophy on inventory management is simple: - Strive for a level of zero inventories. - Produce items at the rate required by the customer. - Eliminate all unnecessary lead times. - Reduce setup costs to achieve the smallest economical lot size - ideally, a quantity of one. - Optimize material flow from suppliers through the production process to the point of sale of the finished product, so that inventories are minimized. - Ensure high quality and dependable just-in-time delivery from suppliers. - Implement a Total Quality Control (TQC) program, which will minimize scrap, rework and resultant delays in production (Naylor). While the just-in-time inventory management philosophy is simple, execution is not. In a just-in-time environment, the supplier should deliver raw materials and other purchased items when they are needed. A blanket purchase order or other suitable form of basic agreement should cover the terms and conditions for procurement. Delivery of the item should be direct to the point of use in the manufacturing plant. It is time consuming and not cost-effective for the materials to be handled in one part of a production line before it is moved to the correct location. It is up to the supplier to ensure a smooth flow of material to support production, which is obtained through optimum communication and coordination between the manufacturing plant and the supplier. It is integral that there is a working relationship between suppliers and the controller of the manufacturing plant. The supplier should be considered by the manufacturing company as an extension of the plant and should be included in all planning which involves his products. Certain individuals in the production plant should be selected to represent the company on matters pertaining to schedules and delivery quantities (Naylor). Several techniques exist for controlling the flow of material from the supplier to the manufacturing company. The specific technique should be selected which would best suit the implementation of the just-in-time concept for the particular item being purchased. Automatic inventory replenishment by the vendor is a technique where the supplier determines the need for required materials based on frequent deliveries to the plant. Depending on the nature of the production process as well as the material involved, this could range from many times a day to a less frequent interval. Visual review of existing inventory by the supplier will determine how much to deliver (Slack). The method of inventory control is not foreign to U.S. commerce and industry; visit a supermarket and see how the baker delivers his goods. He replenishes the baked goods based on a visual review of what is on the shelves. The same is true for soda and candy vendor machines. Those using oil to heat their home are certainly familiar with this type of inventory system; the driver comes by the house periodically and fills the tank. Implementing just-in-time may result in increased transportation costs due to smaller lot sizes and more frequent deliveries. However, in some industries such as chemicals there are significant trade-offs between the economy of longer lead-time and less flexible rail shipments versus more frequent tanker truckloads. Each of these cases must be examined on its own merits and on a continuing basis to determine the optimum solution (Slack). Just-in-time requires flow of material in the exact quantity required and at the exact time; the key word is exact. Regardless of the specific method used to achieve this exact material flow, there must be

GREECE Essay Example | Topics and Well Written Essays - 750 words

GREECE - Essay Example Beautiful nature, geographical position and warm climate make Greece attractive for immigrants. â€Å"Greece's geography, which became especially important after the formation of Europe's borderless Schengen Area, has also contributed to the country's transition to an immigrant-receiving nation. Positioned at the southeastern "gate" of the European Union, and with extensive coastlines and easily crossable borders, Greece has become a common transit country for those seeking entry into Europe† (Kasimis 86). Actually, with the development of globalization, migration became very active. Now it plays a very important role and is defined as â€Å"function of changes in the international division of labor and reconstructing of the global economy, which entails rapid and massive movements of productive factors, including capital and labor† (Icduygu 294). The number of immigrants in Greece is very high. Immigrants from Albania amount to around 60% according to the data of the y ear 2012. 1990s were the period of active immigration from Asian states that now is mostly illegal: illegal immigrants usually come from Iraq, Turkey, Afghanistan, etc. There are a number of factors that influence migration. Poverty is considered to be the most important factor that makes people look for better life in a foreign country. The second important factor is armed conflicts in the countries that made people leave motherland and many of them came to Greece that always has been attractive by its geographic location and financial stability. Active immigration from Asian countries has grown into a serious problem for Greece. Moreover, only small part of immigrants is registered, the rest are illegal. The government of Greece is very concerned about the issue as the number of immigrants is becoming so high that it is very difficult to control the immigration. Some actions have already been done in this direction, but the government still can’t establish the appropriate c ontrol over the issue. The absence of legal protection, racial intolerance that inevitably occurs in the society with very high number of immigrants, and bad working conditions turns the foreign labor into exploitation. In general, immigration in Greece is treated negatively and considered to be undesirable and troublesome for the society and economy of Greece. Speaking about natural resources, it is essential to admit, that Greece does not have plenty of them, so import is needed. The main are marble and petroleum. Last time Greece is concerned about the reduction of petroleum reserves. Aluminum, nickel and magnetite can be also found in Greece. In the 1970th Greece was going through the economic development, this period is characterized by active industrialization. Simultaneously, country started facing serious problems connected with environmental pollution. The situation is especially serious in Athens that faces heavy air pollution. Pollution leads to spread of respiratory illn esses and in addition spoils the monuments Greece is so proud of. In order to overcome this problem, the government has to build a number of stations to monitor pollution. These steps helped reduce the pollution. â€Å"Greece should soon begin to see further environmental progress as a result of management and financial efforts made since the mid-1990s. Its environmental policy has been modernized and driven by EU environmental legislation, a search for improved quality of life in the larger cities (Athens, Thessaloniki) and, to some extent, the
