英语经济语篇中生物隐喻映射模式探析

认知语义学理论认为,隐喻是人类通过事物之间的相似性用某一领域的经验说明或理解另一领域的经验的认知活动,是人类赖以生存的思维模式。国内针对英语经济语篇中的隐喻研究甚少,且多数是宏观层面的理论归纳与实证总结,很少涉及源领域事物特征向目的域映射的微观过程。本文以经济领域中一个突出的概念隐喻——生物隐喻为例,描述和揭示了其内在的隐喻映射模式。

Challenges in Multidisciplinary Systematic Reviewing: A Study on Social Exclusion and Mental Health Policy

In the clinical sciences, systematic reviews have proved useful in the aggregation of diverse sources of evidence. They identify, characterize and summate evidence, but these methodologies have not always proved suitable for the social sciences. We discuss some of the practical problems faced by researchers undertaking reviews of complex and cross‐disciplinary topics, using the example of mental health and social exclusion. The barriers to carrying out social science and cross‐disciplinary reviews are reported and some proposals for overcoming these barriers are made, not all of them tried and tested, and some of them controversial. Using a mapping approach, a wide‐ranging search of both clinical and social science databases was undertaken and a large volume of references was identified and characterized. Population sampling techniques were used to manage these references. The challenges encountered include: inconsistent definitions of social phenomena, differing use of key concepts across research fields and practical problems relating to database compatibility and computer processing power. The challenges and opportunities for social scientists or multidisciplinary research teams carrying out reviews are discussed. Literature mapping and systematic reviews are useful tools but methods need to be tailored to optimize their usefulness in the social sciences.     

Youth violence and weapon mapping: A survey of youth violence in selected districts in Zimbabwe

ABSTRACT

With the rising cases of youth violence in Zimbabwe from different fronts, the study sought to map the nature of the violence, their driving factors, main weapons used and the eventual effects on the victims. The qualitative study adopted a survey form administering questionnaires to youth participants from selected districts in eight non-metropolitan provinces in Zimbabwe. Data were gathered by means of a questionnaire survey e-mailed to the snowball-sampled youth supported by relevant literature review. The analysis of data was done through SSPS, which helped break the questions into minute elements of analysis. The theory of Utilitarian Rational Choice guided the study argument. It was established in the study that indeed the youth across the country are engaged in different forms of violence depending on what is available but either scarce or inequitably distributed or the nature of prevailing political ideology. It was also established that various weapons are used to either injure or inflict pain on victims and the weapons vary with the province depending on various factors. Equally, resultant effects and injuries differ depending on a variety of factors.     

Participants’ productive disruption of a community photo-elicitation project: improvised methodologies in practice

Abstract

This article reports on an attempt to use photo-elicitation to explore contested intergenerational perceptions and experiences of ‘place’ in one English village. Participants actively disrupted the photo-elicitation project and ended up co-creating an enriched research design that allowed them to represent how they experienced ‘place’. The spontaneous, mixed media-elicitation that resulted overturns some of the more straightforward notions that are aligned with photo-elicitation techniques. This article builds on a growing body of critical literature on photo-elicitation and shows how participants’ disruption of a project’s research methods can be both challenging and fruitful in practice. The researcher’s flexibility and willingness to work with participants’ alternative approaches proved extremely effective in allowing participants to communicate their ‘imagined geographies’ and to identify experiences of social inequality. This article explores how the initially problematic in participant involvement can be turned into the productive through the use of ‘improvised methodologies’.

Advancing scientific knowledge through participatory action research

This paper aims to demonstrate the value of participatory action research (PAR) for advancing scientific knowledge as well as for solving practical problems. The article supports the argument through brief summaries of three PAR cases in industry: Norwegian shipping, Xerox Corporation, and the FAGOR group of the Mondragón cooperatives. While noting the practical gains achieved through PAR, the author concentrates particularly on the advances in substantive knowledge and theory that would have been unlikely to emerge out of more orthodox sociological research. The author suggests finally that wider use of participatory action research can have a stimulating effect upon the future development of sociology.     

基于可视化交互式遗传算法中映射方法的分析与研究

提出了一种对基于可视化交互式遗传算法中的非线性映射方法,结合遗传算法在n维空间上快速搜索的优点和人类在二维空间上把握数据整体分布的能力,采用VISOR算法既降低了计算的复杂度,又使数据空间和输出空间上数据点与聚类中心间的距离信息保持相似.仿真结果验证了该方法的可靠性、稳定性和快速性.
