- Description: Plutella xylostella (L.) (Lepidoptera: Plutellidae), also known as diamondback moth, is a destructive insect pest of cruciferous crops (Talekar and Shelton 1993; Shelton 2004). The pest occurs wherever its host plants are cultivated and the global annual cost of damage and control is estimated to be US$4-5 billion (Zalucki et al. 2012). The extensive use of synthetic pesticides for control combined with the high fecundity of P. xylostella has resulted in the pest developing resistance to nearly all classes of insecticides (Grzywacz et al. 2009). Moreover, these chemicals have negative environmental implications and may affect non-target species, some of which are natural enemies of the pest.

- Description: In this paper, three differently sized glutathione (GSH)-capped CdTe@ZnS quantum dots (QDs) have been successfully conjugated to nickel tetraamino-phthalocyanine (NiTAPc) to form different QDs-NiTAPc nanocomplexes. Several techniques such as TEM, FT-IR, time-resolved fluorescence measurement and electronic spectroscopy were employed to characterize the nanocomplex. Bromide ion was chosen as a model anion to test the efficacy of the nanoprobe. The fluorescence of the nanoconjugate was “turned off” upon binding but was progressively “turned on” upon interaction with varying concentrations of bromide ion. Experimental results showed that the quantum size effect of nanocrystal QD determined the overall sensitivity and selectivity of the nanoprobe and followed the order QD563-NiTAPc > QD605-NiTAPc > QD621-NiTAPc. The mechanism of reaction is proposed.

- Description: CdTe and CdTe@ZnS quantum dots (QDs) capped with 3-mercaptopropionic acid (MPA), thioglycolic acid (TGA), or glutathione (GSH) have been employed for the first time as luminescent probes for the sensitive and selective detection of peroxynitrite (ONOO−) in aqueous solution. The sensitivity of the proposed probe followed the order: MPA–TGA–CdTe@ZnS>GSH–TGA–CdTe@ZnS>MPA–CdTe QDs. The varying degree of quenching is elucidated based on the QD–thiolate bond of CdTe@ZnS being more sensitive to oxidation from ONOO− than CdTe. The selectivity of the probe in the presence of co-existing species followed the order: GSH–TGA–CdTe@ZnS>MPA–TGA–CdTe@ZnS>MPA–CdTe QDs. QDs capped with MPA showed less selectivity for ONOO− than GSH. The best limit of detection (LOD) of 12.6 nM was obtained for MPA–TGA–CdTe@ZnS QDs. Time-resolved fluorescence measurements indicated that the interaction between ONOO− and the QDs is static in nature.

- Description: The covalent linking of thiol-capped CdTe@ZnS QDs with cobalt tetraamino-phthalocyanine (CoTAPc) has been successfully carried out. Several techniques such as time-resolved fluorescence measurements, thermal gravimetric analysis,transmissionelectronmicroscopy andspectrophotometric techniques were employed to characterize the nanoconjugates. Covalent binding of the QDs with CoTAPc resulted in the fluorescence quenching of the former. In the presence of varying concentrations of superoxide anion (O2 •−), the fluorescence of the QDs in the conjugate was gradually enhanced and the detection limits obtained were 2.1 and 2.4 nM for the smaller and larger QDs, respectively. Based on the excellent selectivity displayed by the nanoconjugates towards O2 •− over other biologically active species, a potential nanosensor was developed.

- Description: In this study, we have developed a novel nanoprobe for H2O2 based on the conjugation of CdTe@ZnS quantum dots (QDs) to different metal tetraamino-phthalocyanine (MTAPc): (M = (OAc)Al, {OAc = acetate}, Ni and Zn). Chemical coordination of the QDs to the MTAPc resulted in the fluorescence “switch off” of the linked QDs which was associated with Förster resonance energy transfer (FRET). In the presence of varying concentration of H2O2, the fluorescence of the linked QDs was progressively “switched on” and the FRET mechanism between the QDs and the MTAPc was disrupted. The sensitivity/limit of detection of the nanoprobe followed the order: QDs-ZnTAPc (2.2 μM) > QDs-NiTAPc (4.4 μM) > QDs-AlTAPc (9.8 μM) while the selectivity followed the order: QDs-NiTAPc > QDs-AlTAPc > QDs-ZnTAPc. The varying degree of sensitivity/selectivity and mechanism of detection is discussed in detail.

- Description: This research is intended to evaluate and study the challenges confronting NEPAD’s quest for sub regional economic integration in the ECOWAS domain. Political and economic integration has been part of African strategy to overcome fragmentation, marginalization and improve the continent’s position in the global political economy. Indeed, Africa needs integration more than any other continent or region in the world and this is why, it has had a fair share of regional integration arrangements all through her history. Unfortunately, these efforts have not paid off in the dimension of desired expectations. When NEPAD was established, it was given regional integration responsibilities, even though it was not a regional organization. It was mandated to drive regional integration in Africa by supporting the regional integration efforts of the regional economic institutions in Africa. After 10 years of existence, African leaders dissolved NEPAD and in its place, instituted the NEPAD Planning and Coordinating Agency (NPCA). This move was orchestrated by the seemingly slow progress made by NEPAD in this direction. NEPAD and ECOWAS has been working together to promote regional integration, but like in most parts of Africa, the challenges has been seemingly intractable. The study is anchored around the principles of integration as presented by the neo-functionalists theorists. Hence, the research attempted to provide an explanation of the performance and non-performance of NEPAD as a regional integration tool, within the confines of the theory. The findings show that while, there has been some level of success in this venture as evidenced by the projects that are on-going in the sub region, the fact remains that NEPAD did not deliver or actually delivered below expectations. However, this situation is reversible as the study submitted that, there is a future for regional integration in West Africa, Africa and the new NPCA, if the African Union pulls the right levers. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2013

- Description: The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution.

- Description: A well documented epidemic of human intestinal schistosomiasis caused by Schistosoma mansoni occurred at Maun in the seasonal part of the Okavango Delta, Botswana, building from very few cases in the 1950s and early 1960s to a peak prevalence of greater than80% in the 1980s. A retrospective analysis was performed on all available records of the prevalence of S. mansoni in the Maun area and the corresponding flow records of the Thamalakane River. These revealed a statistically significant correlation between prevalence and flow, but only when a lag period was introduced. The correlation was greatest with a lag period of 5–6 years between the rise and fall of discharge and the rise and fall of transmission. Since the hydrological events in the delta follow a cyclical pattern, another epidemic around 2020 appears likely.

- Description: Cooperation is central to collective management of small-scale fisheries management, including marine protected areas. Thus an understanding of the factors influencing stakeholders’ propensity to cooperate to achieve shared benefits is essential to accomplishing successful collective fisheries management. In this paper we study stakeholders’ cooperative behavioral disposition and elucidate the role of various socio-economic factors in influencing it in the Roviana Lagoon, Western Solomon Islands. We employed a Public Goods Game from experimental economics tailored to mimic the problem of common pool fisheries management to elucidate peoples’ cooperative behavior. Using Ostrom's framework for analyzing social-ecological systems to guide our analysis, we examined how individual-scale variables (e.g., age, education, family size, ethnicity, occupational status, personal norms), in the context of village-scale variables (e.g., village, governance institutions, group coercive action), influence cooperative behavior, as indexed by game contribution. Ostrom's framework provides an effective window for conceptually peeling back the various socio-economic and governance layers which influence cooperation within these communities.

- Description: This review article synthesizes the authors' several decades of multidisciplinary natural and social science and applied marine resource management experience in the Asia-Pacific region to examine the strengthening of coastal and marine resource management and conservation using alliances between local communities and external institutions. The objective is to assist the design of resource management and conservation programs that enhance the capacity of coastal communities in Oceania to confront both diminishing marine resources and the effects of climate change by providing guidelines for protecting marine biodiversity and vulnerable ecosystem functions. This article describes a management framework that hybridizes local beliefs and institutions expressed in customary management (CM) with such modern management concepts as marine protected areas (MPAs) and ecosystem-based management (EBM). Hybrid management accommodates the social, political, economic, and cultural contexts of Oceanic communities and, compared with recent or conventional management approaches, can therefore better address fundamental local concerns such as coastal degradation, climate change, sea level rise, weak governance, corruption, limited resources and staff to manage and monitor marine resources, and increasing poverty. Research on the hybridization of management systems demonstrates opportunities to establish context-appropriate EBM and/or other managerial arrangements that include terrestrial and adjacent coastal-marine ecosystems. Formal and informal CM systems are widespread in Oceania and in some parts of Southeast Asia, and if appropriate strategies are employed rapid progress toward hybrid CM-EBM could be enabled.

It also aimed, by making use of the van Hiele model of geometry instruction, to elucidate what possible learning opportunities observed instructional methods could offer learners in the subject. The sample comprised three mathematics teachers from Nigeria and three mathematics teachers from South Africa, all of whom were selected using purposive sampling techniques. Instructional activities in six geometry classrooms were recorded on videotape. The van Hiele learning phases provided the framework for data analysis. The findings of this study indicate that observed teaching methods in geometry classrooms in the participating schools offer learners scant opportunity to learn geometry.

Knowledge on how best to ‘grow’ social assistance, understood as long-term institutions responsible for reducing and preventing poverty, is at a premium. This article examines the expansion of social assistance in Brazil and South Africa, two of the middle income countries widely perceived to have advanced furthest in ‘growing’ social protection. It examines three aspects: the primacy of politics in explaining the expansion of social protection and assistance, the tensions between path-dependence and innovation in terms of institutions and practices, and the poverty and inequality outcomes of social assistance expansion. The article concludes by drawing the main lessons for other developing countries.

- Description: The primary aim of this project is to provide a close contextual and textual analysis of the selected children’s classics: The Wonderful Wizard of Oz, Anne of Green Gables and The Secret Garden using the feminist literary theory. From this perspective I have shown how the selected works of Lyman Frank Baum, Lucy Maud Montgomery and Frances Hodgson Burnett’s writing have contributed to women’s stereotypical roles within society and perpetuated their subjugated position. I have also conducted an examination of the extent to which the female protagonists attempt to emancipate themselves from gender oppression. A comparative study of the selected children’s texts has not yet been conducted and therefore this project serves as a significant contribution to this field of study. An exploration of the historical background of the authors and children’s literature is conducted to provide an overview into the inner workings of the writers’ lives and the historical significance of children’s literature as a genre. The theoretical framework of feminist literary theory is used in the analysis of the selected texts. The connection between feminist literary theory and children’s literature is highlighted and provides further understanding of the purpose of this study. The history of feminism as both a movement and a contemporary literary criticism is explored. Simone de Beauvoir’s The Second Sex is used when analysing the texts’ characters and how they are based on society’s stereotypical gender roles. Luce Irigaray’s Speculum of the Other Woman and This Sex Which is Not One is examined to aid in an exploration of psychological female oppression through feminine and masculine discourse evident in the creation of the novels’ female and male characters. Hélène Cixous’ “The Laugh of the Medusa” and The Newly Born Woman is interrogated according to the stereotypical ideology surrounding the terms masculinity and femininity and how these terms are interpreted in the selected works. Judith Butler’s Gender Trouble and Undoing Gender are additionally explored to assist in the understanding of the concept of gender performativity and through the lens of Butler’s interpolation of gender the move towards the emancipation of women is seen in the selected children’s texts. The close textual feminist analysis focuses on the female protagonists: Dorothy, Anne and Mary as well as the secondary female characters: the wicked witches, Aunt Em, the Queen of the Field-Mice, the princess made from china, Glinda’s female soldiers from The Wonderful Wizard of Oz; Marilla Cuthbert, Rachel Lynde and Diana Barry from Anne of Green Gables and Martha, Mrs Sowerby and Mrs Craven from The Secret Garden. The portrayal of the secondary male characters are additionally explored according to feminist literary theory: The Scarecrow, the Tin Woodman, the Lion and the wizard Oz from The Wonderful Wizard of Oz; Matthew Cuthbert and Gilbert Blythe from Anne of the Green Gables’ and Mr Craven, Colin Craven and Dickon Sowerby from The Secret Garden. The comparison of these children’s classics by Baum, Montgomery and Burnett provides insight into the selected works of all three writers, through the lens offered by feminist literary theory. Through the interrogation of these representative female protagonists found in early children’s literature, an understanding of not only the subordination of women, as evident in literature during this era, is illustrated but also the comprehension that women’s liberation was foreshadowed in these early children’s novels. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2013
