Pre-service Primary Teachers' Perceptions about Principals in Hong Kong: Implications for teacher and principal education

This study aimed to explore pre-service teachers' perceptions and expectations of principals, how these perceptions may influence attitude and behaviour when they start in school and how pre-service teachers' perceptions of the principalship may have been formed. In general, pre-service teachers do not expect to receive assistance from the principal during their first months of teaching. Past experience of principals has resulted in clear expectations of principal support, particularly in respect to beliefs about the influence of hierarchy, school authority and principal's workload. Others, however, expect the principal to be receptive to and supportive of innovations. Some expect support from their colleagues whilst others believe they must rely on themselves. Furthermore, the sources of beliefs about the principalship are predominantly formed during pre-service teachers' experiences in school life and teaching practice. Many of their images of the principalship tend to be negative.     

Disenchanted Evenings: The social organization of talk in parent-teacher consultations in UK secondary schools

Parent-teacher consultations represent something of a 'black hole' in our understanding of educational practices. This study, based on audio-recordings, examines the structure and the fine detail of these brief encounters. We identify some similarities with doctor-patient consultations. Teachers are accorded the right to give an uninterrupted 'diagnosis'; and they maintain knowledge differentials through their use of specialist vocabularies and professional registers, while down-playing parents' deployment of their own 'privileged' knowledge of the student. However, we argue that teachers do not unequivocally have the upper hand: that issues of power, identity, competence and moral conduct are at stake for all involved. The complex negotiations and skirmishes that take place during these encounters testify to their precarious location on the boundary between the two institutions of home and school. In requiring homes to render themselves visible, schools also, fleetingly, expose themselves to the risk of critical scrutiny from those on the outside.     

Technology in the Hands of the Extension Officers‐‐Agricultural Extension in Jamaica and Ghana

This paper describes a technology‐based research pilot project currently being undertaken by The Commonwealth of Learning (COL) with Jamaica's Rural Agricultural Development Authority (RADA) and the Women in Food and Agricultural Development (WIFAD) in Ghana. A feasibility study undertaken concluded that the use of video with non‐linear field‐based video production equipment can be effective in demonstrating farming techniques. The premise is that video production can be done at the parish/regional level, allowing farmers and agro‐food processors to directly relate to the information relevant to their own agricultural contexts and situations. The paper describes the findings of the feasibility study and the mix of media that has been utilised for the pilot.     

Shaping a gender equality policy in higher education: which human capabilities matter?

South African institutions still confront gendered inequalities, irrespective of transformative national policies, compounded by the absence of a national gender equality policy for higher education. We therefore explore the potential of the capabilities approach (CA) to inform policy formation and argue for the development of a policy for higher education institutions based on opportunities for valuable functionings as the informational basis for gender equality. Using one university as our case study, data from 38 interviews with female and male students were analysed as part of a longitudinal study on Gender, Empowerment, Agency and Higher Education. The data reveal which opportunities these women and men find important for their personal development and directly and indirectly for gender equality. We conclude by discussing the implications of the data for stimulating public dialogues towards formulating a capabilities-based gender equality policy, as well as reflecting on the broader contributions the CA brings to policy development.     

A microfluidic device to study cancer metastasis under chronic and intermittent hypoxia

Metastatic cancer cells must traverse a microenvironment ranging from extremely hypoxic, within the tumor, to highly oxygenated, within the host''s vasculature. Tumor hypoxia can be further characterized by regions of both chronic and intermittent hypoxia. We present the design and characterization of a microfluidic device that can simultaneously mimic the oxygenation conditions observed within the tumor and model the cell migration and intravasation processes. This device can generate spatial oxygen gradients of chronic hypoxia and produce dynamically changing hypoxic microenvironments in long-term culture of cancer cells.     

Family Interactions and the Development of Moral Reasoning

The study examined parents' role in their children's moral reasoning development. Parents' level of moral reasoning and interaction styles used in discussion of moral issues with their child were used to predict the child's moral development over a subsequent 2-year interval. Participants were 63 family triads (mother, father, and child) with children drawn from grades 1, 4, 7, and 10. They individually responded to a moral reasoning interview and then, as a family, discussed both a hypothetical and real-life moral dilemma. Children were reinterviewed 2 years later. Results indicated that parents did accommodate to their child's level of moral reasoning when in actual dialogue. Distinct differences in interaction styles were found between the 2 contexts (hypothetical vs. real-life dilemma discussion) and between parents and children. Children's moral development was best predicted by a parental discussion style that involved Socratic questioning and supportive interactions, combined with the presentation of higher-level moral reasoning. Implications of these findings for the understanding of parents' role in children's moral development are discussed.
