The aim of this research was to examine how university literacy is constructed at a university in the Arabian Gulf and to evaluate the appropriateness of this construction where students of a low level of English are exposed to academic English (Right from the Start). Unpacking this construction is a complex task and to gain even a limited insight into the numerous Discourses, epistemologies and pedagogies constituting the construction of university literacy at Gulf universities, a stratified approach that probes the layers of ‘reality’ is necessary. Therefore, a critical realist approach is engaged, along with a variety of methods to probe the layers of the phenomenon. In terms of thesis organization, the traditional empirical structure common to the Social Sciences and the argumentative structure common to the Humanities are integrated. While the information obtained by a variety of methods is analysed and conclusions are reached, this material is also used along with additional literature to support the central contention that university literacy and academic English are possible ‘right from the start’, if the students’ literacy is examined from a certain perspective and if there is an appropriate pedagogy which promotes the desired literacies. This combination of thesis structures would be deemed appropriate in the critical realist ontological framework since the rigour of the thesis lies both in its “reliability” resulting from the empirical data and its focus on the ‘real’; and its “reflexivity” and “persuasivness” arising from the transparently ‘critical’ argument of the thesis (Cadman 2002). In order to conduct the empirical research, the lenses suggested by each of the major views of literacy as outlined by Lea and Street (1998) - namely the “study skills” view, the narrow “academic socialization view” and the “academic literacies view” are utilized in succession. However, the central argument is revealed as the manifestations of each ‘view’ of literacy in the specific context are examined, the research outcomes obtained by utilizing each view in succession are outlined and both are critiqued from the perspective of the “academic literacies” view. Corpus research is undertaken from a “study skills” perspective and the effect of the vocabulary taught to the students on their use of vocabulary in their writing is examined. Also, using the “study skills” lens, the students’ “global language development” in terms of changes or fluctuations in “fluency, accuracy and complexity” (Wolfe-Quintero, Inagaki et al. 1998) over a period of at least three semesters is examined. Utilizing a narrow “academic socialization lens”, studies conducted at the University on learning strategies and motivation and the comments made by respondents in interviews and on an electronic discussion board are compared to comments made by teachers and lecturers. Major flaws in these views of academic literacy are acknowledged and the way each view manifests itself in the Discourse(s) prevalent at this particular university is demonstrated. Finally, Discourses evidenced in the student interviews in particular, are unpacked and then compared and contrasted with those in the lecturer interviews as well as the curriculum and other university documents. The limitations of the study are examined and suggestions for further research and ways to address ‘problems’ associated with university literacy are given.

The purpose of this study is to analyze the foreign policy outcomes of the Gulf Cooperation Council (GCC) to understand the extent to which a Regional Intergovernmental Organization (RGO) consisting of developing nations is able to promote regional cooperation. Much of the literature on integration and the formation of Intergovernmental Organizations was developed with regard to western nations. These approaches are examined for their contributions to foreign policy behavior analysis and with respect to understanding why small and developing nations join such organizations. Final analysis of the outcomes using two scales to measure the organization's ability to promote regional cooperation reveal that the level of success was moderate and the level of political action undertaken by the GCC was generally moderate to low. Leadership is supportive of the organization but both external and internal factors contribute to the modest levels achieved so far. Issues of national sovereignty and a decade of regional conflicts affected the ability of the organization to achieve greater levels or regional cooperation.

In recent years, gull control has become closely tied to seabird restoration in the Gulf of Maine. Herring (Larus argentatus ) and Great Black-backed (L. marinus) gulls are the principal targets of control, yet anecdotal reports suggest that gull predation remains an important source of egg and chick mortality at many managed seabird colonies. The main objective of this study was to examine the impact of gull predation on the reproductive success of several waterbird species nesting at restoration sites in Maine. Particular emphasis was placed on understanding gull foraging behavior, identifying foraging constraints, and applying this knowledge to management of gulls and small seabirds. / Productivity of Common (Sterna hirundo), Arctic ( S. paradisaea), and Roseate (S. dougallii) terns was monitored and daily predation watches were conducted at Eastern Egg Rock, Maine from 2003-2005. In 2004 and 2005 only, attempts were made to shoot gulls preying on terns. Shooting failed to eliminate predation, and tern predation risk was influenced by nest location, but not year. Common and Arctic terns experienced heavy predation in all years, but Roseate Tern nests were seldom depredated, presumably because Roseates selected nest-sites with more cover. Great Black-backed Gull predation was influenced by visibility, tidal state, and year, while Herring Gull predation depended only on the stage of the tern breeding cycle. There was little evidence that gulls preyed selectively on unfit chicks. The limitations of shooting are discussed and non-lethal alternatives suggested. / Common Eider (Somateria mollissima dresseri) nest (hatching) success, habitat use, and duckling survival were studied at Stratton Island, Maine in 2004-2005. Eiders nested in a variety of habitats offering vegetative cover and enjoyed high nest success. Duckling survival was negligible however, because of opportunistic, group attacks by Great Black-backed Gulls. Glossy Ibis (Plegadis falcinellus) also appeared to suffer heavy gull predation, with adults occasionally attacked in flight. In 2006, gull displacement walks, gull nest/egg destruction, and occasional shooting were used on a trial basis and may enhance future eider production.

Three species of Sargassum are the P10st abundant intertidal macroalgae at Puerto Penasco, Sonora, Mexico. Sargassum johnstonii Setchell & Gardner, S. herporhizum Setchell & Gardner, and S. sinicola Setchell & Gardner var. camouii (Dawson) Norris & Yensen are zoned on emergent reef in low intertidal areas. Sargassum johnstonii occurs in a zone above dense stands of S. herporhizum, and scattered patches of S. 8inicola occur on the lowest emergent reef. Sargassum sinicola, the most abundant species, predominates in pools throughout the intertidal zone. In mid-intertidal pools the species show the same zonation with respect to water depth that they do on emergent reef. Ecological separation is clear, the species occurring in different vertical zones or different habitats (pools or emergent reef). At some sites where S. herporhizum is rare or absent, the upper limit of emergent S. sinicola plants shifts upward probably because of a combination of physical and biological factors. The three species in this highly seasonal region reach maximum size and canopy cover in early spring. All produce fertile receptacles in the spring and shed their branches and die back in summer. Surviving S. sinicola persist through the summer at larger sizes, recommence growth and produce a second crop of receptacles in the fall; the other two species grow but are not fertile until the following spring. The species differ in allocation of biomass to vegetative and sexual reproductive structures. Sargassum herporhizum invests a high proportion of its wet and dry biomass into extensively branched, rhizoidal holdfasts. The holdfasts of the other two species are smaller relative to their upper branches, and are not rhizoidal. Experimental clearings showed that S. herporhizum was the most effective at recovering continuous space after disturbance and also after normal summer dieback. Sargassum johnstonii and S. sinicola produce large volumes of sexual receptacles on buoyant branches, which have the potential for wide dispersal, whereas S. herporhizum produces a relatively small volume. A trade-off between short-range vegetative encroachment abilities and potential for long-range dispersal of sexual propagules may have occurred in the evolution of reproductive strategies of these Sargassum species.
