Community Work Research through Co-Operative Inquiry in Timor-Leste,Australia and Peru: Insights into Process

Co-operative inquiry is an under-explored method in community-based research. Its democratic approach involves a group of “co-researchers” collaboratively inquiring into a mutually-agreed research topic through systematic cycles of reflection and action. This article shares the process, outcomes, and methodological reflections of three co-operative inquiries that were conducted as part of an international study regarding love in community work. Groups of up to 10 community workers in rural villages in Timor-Leste, Australia, and Peru engaged in co-operative inquiry to collaboratively develop new knowledge to inform practice. The article analyses data regarding co-inquirer experiences of the methodology, and identifies the strengths and challenges of the co-operative inquiry method to support the collective generation of new knowledge. The article concludes that co-operative inquiry involves shared power, participation, action, and contextual reflexivity, and is a useful method for community workers to collaboratively develop innovative approaches to community work practice through cycles of reflection and action.     

Investigations of ZnO thin films deposited by a reactive pulsed laser ablation

Highly transparent ZnO thin films were deposited at different substrate temperatures by pulsed laser deposition in an oxygen atmosphere.The thin films were characterized by various techniques including X-ray diffraction,scanning electron microscopy,optical absorption,and photoluminescence.We demonstrated that oriented wurtzite ZnO thin films could be deposited at room temperature using a high purity zinc target.Variable temperature photoluminescence revealed new characteristics in the band edge emission.The...     

Mice overexpressing human uncoupling protein-3 in skeletal muscle are hyperphagic and lean

Uncoupling protein-3 (UCP-3) is a recently identified member of the mitochondrial transporter superfamily that is expressed predominantly in skeletal muscle. However, its close relative UCP-1 is expressed exclusively in brown adipose tissue, a tissue whose main function is fat combustion and thermogenesis. Studies on the expression of UCP-3 in animals and humans in different physiological situations support a role for UCP-3 in energy balance and lipid metabolism. However, direct evidence for these roles is lacking. Here we describe the creation of transgenic mice that overexpress human UCP-3 in skeletal muscle. These mice are hyperphagic but weigh less than their wild-type littermates. Magnetic resonance imaging shows a striking reduction in adipose tissue mass. The mice also exhibit lower fasting plasma glucose and insulin levels and an increased glucose clearance rate. This provides evidence that skeletal muscle UCP-3 has the potential to influence metabolic rate and glucose homeostasis in the whole animal.     

FDTD计算功率变换器近场到近/远场的转换

从理论上分析了利用时间有限差分法由近场到近场或远场转换的频域和时域两种方法，并选择时域的方法计算在FDTD计算范围内一给定点的电场值，与直接利用FDTD法得到的结果相比较，两者非常一致；最后利用该方法计算了功率变换器FDTD计算范围外一给定点的电磁场时间响应．     

The Participation Imperative in Co-operative Inquiry: Personal Reflections of an Initiating Researcher

Participation has become an imperative in international development. In particular, participatory approaches to development research are believed to support empowerment through collective development of knowledge and action. Yet there are broad interpretations of participation, ranging from passive participation and information exchange to empowered participation through self-mobilisation. As such, development researchers may claim to use a participatory approach without yielding power and agency to citizens involved in the research. This is a reflexive article about a development researcher’s experience in applying a participatory worldview through co-operative inquiry, a research approach that attempts to engage emancipatory forms of participation. The article begins with a critical analysis of literature regarding participation, the participatory paradigm and participation in the co-operative inquiry. The author then analyses her personal experiences, challenges and strategies as initiating researcher to actualise empowering forms of participation in three co-operative inquiries. The article emphasises that researchers must “let go” of their power, control and personal agenda to support empowering participation.
