"Show me your impact": evaluating transitional justice in contested spaces

This paper discusses some of the most significant challenges and opportunities for evaluating the effects of programs in support of transitional justice - the field that addresses how post-conflict or post authoritarian societies deal with legacies of wide spread human rights violations. The discussion is empirically grounded in a case study that assesses the efforts of the International Development Research Centre (IDRC) and one of its Guatemalan partners to evaluate the effects of a museum exposition that is attempting to recast historic memory and challenge racist attitudes in post-conflict Guatemala. The paper argues that despite the increasing trend to fund transitional justice programs, many international aid donors are stuck in traditional and arguably orthodox paradigms of program evaluation. This is having a negative effect not only upon the administration of aid but also upon how transitional justice research is perceived and valued by local populations. The case study experience indicates that there is no perfect evaluation model or approach for evaluating transitional justice programming - only choices to be made by commissioners of evaluation, evaluators, and those being evaluated. These are profoundly influenced by the extreme politics and moral values that define transitional justice settings as contested spaces in which calls to remember the tragic past must be balanced with aspirations to re-build a hopeful future.     

A feminist revisiting of the insider/outsider debate: The “outsider phenomenon” in rural Iowa

This article draws upon findings from an ethnographic study of two towns in rural Iowa to examine the adequacy of the insider/outsider distinction as a guideline for evaluating and conducting ethnographic research. Utilizing feminist standpoint and materialist feminist theories, I start with the assumption that, rather than one “insider” or “outsider” position, we all begin our work with different relationships to shifting aspects of social life and to particular knowers in the community and this contributes to numerous dimensions through which we can relate to residents in various communities. “Outsiderness” and “insiderness” are not fixed or static positions, rather they are ever-shifting and permeable social locations illustrated in this case study by the “outsider phenomenon.” Community processes that reorganize and resituate race-ethnicity, gender and class relations form some of the most salient aspects of the “outsider phenomenon.” These dynamic processes shaped our relationships with residents as ethnographic identities were repositioned by shifts in constructions of “community” that accompanied ongoing social, demographic, and political changes.     

教育研究方法论反思:实证与思辨

教育研究中的实证问题在于实证技术化与学术的反实证性以及自身否认价值关涉的方法论缺陷;教育研究中思辨问题则形式化、庸俗化,缺乏思辨的矛盾、激情和魅力。其共性问题在于对教育实践问题的漠视,其出路在于研究者方法论的开放与创新。

Beyond the mirror towards a plurilingual prism: exploring the creation of plurilingual ‘identity texts’ in English and French classrooms in Toronto and Montpellier

In an age of transnational mobility, there has been a growing recognition of the need for both English and French mainstream classroom teachers to be trained to teach increasingly plurilingual student populations. In this article, I begin by describing the context for an exploratory comparative and collaborative ethnographic action research study in four English and French schools in Toronto, Canada and one school in Montpellier, France that engaged children as co-researchers of their lived plurilingualism. I analyse in particular the process of creating plurilingual multimodal books with students and teachers across the five different school cases. This paper focuses on the iterative ‘identity text’ creation process across all five schools by examining one plurilingual identity text from each case, along with students’ research conversations about their creative productions, and interviews with their classroom teachers and parents. Finally, I summarize five features of inclusive plurilingual pedagogy that emerged across the five cases and call for further collaborative research across English and French schools and scholarly communities investigating creative plurilingual language and literacy production in the twenty-first century.     

What if gender became an essential,standard element of Vulnerability Assessments?

Vulnerability Assessments (VAs) can be useful tools for providing key insights for non-government organisations and other development actors, including governments. Not only can they provide an extensive, ‘landscape-wide’ understanding of vulnerability and its underlying causes in a specific context, but this understanding can be jointly owned by all participants. They can thus be used for designing risk reduction and resilience-building measures, programmes, or projects that affect specific groups within a community or the landscape. Beyond that, VAs can provide a platform that promotes interaction among otherwise disconnected stakeholders, as well as the evidence and argumentation for community groups to engage in advocacy with local and municipal/district authorities. This article draws on our combined experience as development practitioners, and considers what we have learnt about the importance of integrating gender issues into VAs.     

论品特威胁喜剧中的疾病情感隐喻

人本观基础上的后现代主义视野下的隐喻观可以看作是隐喻发展的第四阶段。隐喻表达在抽象情感的理解与表达中起着至关重要的作用。从疾病是情感的维度对品特威胁戏剧进行语言考察,可以看出剧中大量出现的疾病是情感的隐喻,盲、哑、疯、麻风病、风湿病、癫痫病等各种疾病映射了剧中人物内心的极度压抑,以及人物内心的不安、惊恐与危机感,折射出了存在主义的哲学思想。情感隐喻具有经验基础,是为戏剧主题服务的。     

Approximating probability density functions in hybrid Bayesian networks with mixtures of truncated exponentials

Mixtures of truncated exponentials (MTE) potentials are an alternative to discretization and Monte Carlo methods for solving hybrid Bayesian networks. Any probability density function (PDF) can be approximated by an MTE potential, which can always be marginalized in closed form. This allows propagation to be done exactly using the Shenoy-Shafer architecture for computing marginals, with no restrictions on the construction of a join tree. This paper presents MTE potentials that approximate standard PDF’s and applications of these potentials for solving inference problems in hybrid Bayesian networks. These approximations will extend the types of inference problems that can be modelled with Bayesian networks, as demonstrated using three examples.
