Teacher education in a global context : towards a defensible theory of teacher education

This paper examines some of the effects of globalisation on education and teacher education. In particular it considers the contradictory demands of economic and cultural forms of globalisation, and between globalisation and localisation. Attempts to construct an 'education space' in Europe and Asia are considered and various responses of teacher education systems are outlined. A defensible theory of teacher education is presented around the transformation of curriculum, pedagogy, assessment and the practicum: one that might allow a creative response to the contradictions of globalisation.

A spill-over theory of international trade unionism

This paper use neo-functionalist and institutionalist theories of geo-political integration to develop a theory of international trade unionism. In brief, the theory asserts that the type of international ‘context’ in which international trade unions operate presupposes the types of ‘imperatives’ that will dominate their interests and concerns. These imperatives are taken to operate along one of three dimensions - industrial, political and ideological, and are seen as evolving in accordance with the ‘logic of spill-over’ in global and sub-global integration processes. Using this interpretation the discussion provides reasons as to why ideological imperatives have historically dominated international trade union thinking, the only exception being regional trade unions operating in Europe, which have evolved beyond the ideological to embrace industrial and political imperatives in their modes of organisation and operation.

Sport-based entrepreneurship : towards a new theory of entrepreneurship and sport management

The entrepreneurship and sport management disciplines have grown significantly in the past decade. Sport is an entrepreneurial process as innovation and change are key elements of sport. The aim of this paper is to develop a theory of entrepreneurship in sports management by investigating the relationship between entrepreneurship and sport. The rapidly growing and developing sport marketing discipline provides a basis in which to understand how entrepreneurship occurs through innovation, proactiveness and risk taking activities. This paper discusses the connection between the entrepreneurship and sports management fields and argues that there needs to be more integration with the two fields of study and traditional entrepreneurship theory. A theory of sport-based entrepreneurship is developed and different types of entrepreneurship that occur in sports management are examined. Suggestions for future research and implications for practitioners are discussed.

Toward a receiver-based theory of knowledge sharing

Managers and researchers alike have sought new ways to address the challenges of sharing dispersed knowledge in modern business environments. Careful consideration by sharers of receivers' knowledge needs and behaviours may improve the effectiveness of organisational knowledge sharing. This research examines how sharers react to their perceptions of receivers' knowledge needs and behaviours when making choices relating to sharing knowledge. The focus of this article is to propose and empirically explore a theoretical framework for a study of the role of the receiver in knowledge sharing - receiver-based theory. Data collected from two case studies highlight a key role played by perceived receiver knowledge needs and behaviours in shaping sharer choices when explicit knowledge is shared. A set of receiver influences on knowledge sharing is provided that highlights key receiver and sharer issues. The paper concludes that companies should develop better ways to connect potential sharers with receivers' real knowledge needs. Further, the findings suggest that sharing on a need-to-know basis hinders change in organisational power structures, and prevents the integration of isolated pockets of knowledge that may yield new value. © 2008, IGI Global.

Does the theory of planned behaviour explain condom use behaviour among men who have sex with men? A meta-analytic review of the literature

The aim of this meta-analysis was to explore whether the constructs in the theory of planned behaviour (TPB; i.e., attitude, subjective norm, perceived behavioural control, intention) explain condom use behaviour among men who have sex with men (MSM). Electronic databases were searched for studies that measured TPB variables and MSM condom use. Correlations were meta-analysed using a random effects model and path analyses. Moderation analyses were conducted for the time frame of the behavioural measure used (retrospective versus prospective). Attitude, subjective norm and perceived behavioural control accounted for 24.0 % of the variance in condom use intention and were all significant correlates. Intention and PBC accounted for 12.4 % of the variance in condom use behaviour. However, after taking intention into account, PBC was no longer significantly associated with condom use. The strength of construct relationships did not differ between retrospective and prospective behavioural assessments. The medium to large effect sizes of the relationships between the constructs in the TPB, which are consistent with previous meta-analyses with different behaviours or target groups, suggest that the TPB is also a useful model for explaining condom use behaviour among MSM. However, the research in this area is rather small, and greater clarity over moderating factors can only be achieved when the literature expands.

On global dissipativity of nonautonomous neural networks with multiple proportional delays

This brief addresses the problem of global dissipativity analysis of nonautonomous neural networks with multiple proportional delays. By using a novel constructive approach based on some comparisontechniques for differential inequalities, new explicit delay-independentconditions are derived using M-matrix theory to ensure the existence ofgeneralized exponential attracting sets and the global dissipativity of thesystem. The method presented in this brief is also utilized to derive ageneralized exponential estimate for a class of Halanay-type inequalitieswith proportional delays. Finally, three numerical examples are given toillustrate the effectiveness and improvement of the obtained results.

Global distribution of permian conulariids and palaeobiogeographical implications

Previously, minimal work has been carried out on conulariids due to their rare occurrences and resultant biostratigraphical limitations. The palaeobiogeographical distribution of Permian conulariids suggests that they have a marked preference for cold to cool-water regions, that they are significant indicators for migration patterns, and that they can potentially provide information on the palaeogeographical configuration and movement of terranes. Permian conulariids are found in Australia, India, New Zealand, Pakistan, Iran, Afghanistan, Kashmir, China, Japan, Russia, Germany, Canada, United States of America, and Bolivia. The diversity of Permian conulariids is markedly higher in the polar regions than in the palaeoequatorial region.

Permian conulariid genera include Notoconularia Thomas 1969, Gondaconularia Waterhouse 1986, Cheliconularia Waterhouse 1986, Neoconularia Sugiyama 1942, Calloconularia Sinclair 1952, Diconularia Sinclair 1952, Paraconularia Sinclair 1940, Mesoconularia Boucek 1939 and Conularia Sowerby 1821. This paper describes two new species of conulariids: Diconularia meadepeakensis sp. nov. from the Phosphoria Formation (Guadalupian), Idaho, USA and Paraconularia kazanensis sp. nov. from the Sokian Horizon (?Roadian), Volga Region, Russia.

Global review of permian Tyloplecta muir-wood and cooper, 1960 (Brachiopoda): morphology, palaeobiogeographical and palaeogeographical implications

A global review of the stratigraphical and geographical distribution of Tyloplecta reveals that the genus ranges in age from Kungurian to Changhsingian (Middle to Late Permian). Tyloplecta first evolved in South China in the Kungurian (late Early Permian). The genus went through its first diversification in the Guadalupian, suffered a major extinction at the end of the Guadalupian, and re-diversified in the Wuchiapingian. T. yangtzeensis persisted into the Changhsingian as the only survivor of the genus involved in the end-Permian mass extinction. Palaeogeographically, South China is not only the centre of origin for the genus but also an area of diversification and evolution. In addition to South China, Tyloplecta has also been recorded from the Far East Russia, Japan, central Thailand, Laos, Cambodia, Qiangtang Terrane of Tibet, Salt Range, Iran, Armenia, Hungary, Yugoslavia, and Slovenia. This geographic spread suggests that Tyloplecta was primarily restricted to the Palaeotethys and is indicative of warm-water palaeoequatorial conditions. Its presence in some of the northeast Asian terranes (e.g., parts of Japan and Far East Russia) and in the Salt Range (Pakistan) and central and north Iran (part of the Cimmerian microcontinents) demonstrate that the genus invaded the middle palaeolatitudinal regions in both hemispheres during the late Middle Permian in response to increased shallow marine biotic communications between Cathaysia in the eastern Palaeotethys and southern Angaraland, and between Cathaysia and Peri-Gondwanaland. The invasion of Tyloplecta (and some other taxa) into the southern shore waters of Angaraland may be explained by assuming ocean surface current connections and close palaeogeographical proximities between the South China, Sino-Korea and Bureya blocks. In comparison, the invasion of Tyloplecta into the Peri-Gondwanaland region is more likely a result of reduced palaeogeographical distance between South China and Peri-Gondwanaland and the appearance of the Cimmerian microcontinents as migratory stepping stones.
