Foraging behaviour of king penguins (Aptenodytes patagonicus) in relation to oceanography at South Georgia and Kerguelen

Understanding the levels of variability in oceanographic features where marine predators forage is critical for understanding variability in an animal's foraging behaviour and reproductive success, and for assessing their potential reactions to environmental change. In this thesis, I examine the foraging behaviour of king penguins (Aptenodytes patagonicus) in relation to oceanographic features in both horizontal and vertical dimensions. I used ARGOS and Global Positioning System tracking data combined with Time-Depth-Temperature-Recorder data to follow the at-sea movements for penguins breeding at South Georgia and Kerguelen. Combining penguin behaviour with oceanographic data at the surface and at depth allowed me to explore how animals adjust their horizontal and vertical movements in response to their environment. In this context I investigated how horizontal habitat use may relate to different Antarctic Circumpolar Current frontal zones, and how hydrological structures at depth may impact diving behaviour. At both study locations, the Polar Front (PF) and cold-water features of southern origin were key features used during foraging. The importance of local habitat was reflected in their use of mesoscale eddies at South Georgia, and bathymetry-related upwelling at Kerguelen. The main features used at depth, during prey pursuit, were the thermocline and Winter Water. Penguins also explored Circumpolar Deep Water, which appears to represent an important foraging niche for birds when under increased breeding or environmental constraints. Variability in the PF and in cold-water features in the foraging area significantly affected penguin behaviour. For example, penguins showed altered behavioural responses and low reproductive success following shifts in key oceanographic features during one breeding season. My study of king penguin foraging behaviour in two sectors of the Southern Ocean has generated these key insights into foraging relationships with oceanography, and into penguin's adaptive capacities to environmental variability. This is of importance for assessing possible reactions of king penguins towards environmental change

Liveability analysis of gated and non-gated low middle income communities in kuala lumpur, Malaysia

The aim of this paper is to examine the liveability conditions in gated and non-gated low middle income communities in Kuala Lumpur where rapid urban growth has led to many disruptions in the urban living environment. Hence, a livability framework was developed with dimensions from housing condition, economic condition, functional environment, social relations and community safety towards achieving the research objectives of – a) to study the liveability level in gated and non-gated communities, b) to compare the level of liveability between gated and non-gated communities, and c) to determine the dimensions and indicators which influence the level of liveability in both communities. Residents’ views were collected through a questionnaire survey which consisted of twenty-four indicators of liveability belonging to five dimensions from three communities in Kuala Lumpur. Two communities belong to non-gated and one community had gated living status. The findings of the research revealed that gated community has a better living conditions compared to the non-gated community. Thus, this research can be used as a turning point to improve the living environment of both gated and non-gated communit

A remote Bidayuh area in Sarawak and schooling :a theoretical exploration of socio-cultural transmissions with reference to change conflict and contradiction

The theoretical exploration attempts to explain the structure, and changes in the structure, of socio-cultural transmissions between a socially unstratified cognatic social structure and different levels of schooling. Using models based on Bernstein's concepts of classification and framing, it is argued that the village communities have integrated codes of socio-cultural transmissions and production. Between the two categories of transmission and production a simple systemic relationship exists. Egalitarian relations are shown to typify Bidayuh society and to constitute the dominant socio-cultural category reproduced by the transmission code. Schooling as an intrusive social institution is relatively autonomous of production. It is shown that the socio-cultural transmissions of schooling are based on a collection code, which reproduces inegalitarian relations. This reproduction was initially a refraction of alien British society and culture; but latterly became a reflection of local communal ethnicity as socio-historical formations and Malaysia's national ideology (Rukunegara). These reflections are affected by development capitalism, Chinese economic power, Malay political power and Melanau political leadership. The school's collection code is in conflict with and contradictory to the integrated codes of the Bidayuh village communities, and whilst inhibiting successful schooling,it also precipitates social de-regulation of the person. Additionally, the relative autonomy of schooling and its extended systemic relationship with modes of production in Sarawak are potential social de-regulators of the person for the majority in a complex social structure with few common values. A general conclusion is that schooling will remain a serious threat to social order and that the policy of promoting national unity and a national culture through schooling is not likely to succeed

New Insights into the Pathogenesis and Therapies of IgA Nephropathy

IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide and a frequent cause of kidney failure. Better understanding of the pathogenesis of IgAN and the related genetic, immunological, and cellular susceptibility factors are needed to enable the development of effective disease-specific therapy. This book brings together international experts to provide clinical and experimental studies and reviews with an emphasis on early diagnosis, prognosis, disease pathogenesis, determination of disease activity, and new strategies for treatment for IgAN
