On the $$L_p$$ norms of kernel regression estimators for incomplete data with applications to classification

We consider kernel methods to construct nonparametric estimators of a regression function based on incomplete data. To tackle the presence of incomplete covariates, we employ Horvitz–Thompson-type inverse weighting techniques, where the weights are the selection probabilities. The unknown selection probabilities are themselves estimated using (1) kernel regression, when the functional form of these probabilities are completely unknown, and (2) the least-squares method, when the selection probabilities belong to a known class of candidate functions. To assess the overall performance of the proposed estimators, we establish exponential upper bounds on the \(L_p\) norms, \(1\le p<\infty \), of our estimators; these bounds immediately yield various strong convergence results. We also apply our results to deal with the important problem of statistical classification with partially observed covariates.     

Mining,indigeneity, alterity: or,mining Indigenous alterity?

In this special issue on ‘extraction’, we think critically about two urgent and entangled questions, examining the political economy of mining and Indigenous interests in Australia, and the moral economy of Indigenous cultural difference within Cultural Studies and Anthropology. In settler colonial states such as Australia, Indigenous cultural difference is now routinely presented as commensurate with, rather than obstructive of, extractive industry activity. Meanwhile, the renewed interest in ‘radical alterity’ across these disciplines has seen a movement away from regarding authoritative claims about ‘others’ as morally suspect – as only extracting from or mining Indigenous worlds for insights and academic prestige. The ‘ontological turn’, however, leads us to question the empirical status of the ontologies circulating through academic discussions. What happens when Indigenous people disappoint, in their embrace of environmentally destructive industries such as mining, for example? We argue that in cases where ‘they’ are not as different as ‘we’ might hope them to be, scholars should be concerned to foreground the potential role of colonial history and processes of domination in the production and reduction of ontological difference. Second, we call for critical assessment of the political, epistemological, and social effects of both academic and societal evaluations of difference. We conclude by urging for a scholarship that does not pick and choose between agreeable and less agreeable forms of cultural difference.     

Reflections on a meta-analysis: Crystallizing thinking about SCCT

This article provides my reflections and comments on the meta-analysis of situational crisis communication theory (SCCT) presented in this issue. The meta-analysis helps to crystallize strengths and weaknesses of SCCT and the research generated by the theory. No theory is perfect and every theory has limitations/boundaries. The meta-analysis helps to identify the boundaries for SCCT helping to understand when the theory works and when there are better options for informing crisis communication. By reflecting on the extant research, we can plot the direction for future research utilizing SCCT.     

Self-efficacy enhanced in a cross-cultural context through an initiative in under-resourced schools in KwaZulu-Natal,South Africa

This paper discusses the Khanyisa Programme, an initiative in KwaZulu-Natal, South Africa, where learners from under-resourced schools are supported by teachers and high achievers in Grade 11 and 12 from a previously advantaged state school under apartheid. A qualitative, evaluative study was undertaken to identify key elements in the ongoing success of the programme and collect participant suggestions for improvement. The findings, discussed within the framework of self-efficacy theory, identified enormous gains by Khanyisa learners, leading to vastly improved career prospects.     

From Health Crisis to Rights Advocacy? HIV/AIDS and Gay Activism in China and Singapore

The relationship between HIV/AIDS and gay activism has been primarily informed by the American experience and understudied in nondemocratic contexts. Drawing upon qualitative research on China and Singapore, we refine understanding of HIV/AIDS’ influence on the development of gay activism under authoritarian conditions, by examining the processes through which activist organizations interact with laws and regulations, political norms, HIV/AIDS funding, and government responses to both HIV/AIDS and collective organizing. We show how HIV/AIDS’ influence plays out in multiple patterns, depending on the strategic responses that gay activists select from a constrained range of options to shape their organizations’ destinies. Therefore, we provide insights for development agencies and international donors into whether and how international assistance intended to encourage activism and wider social change are mediated by political and legal controls on local activism.     

Review of outcome research on marital and family therapy in treatment for alcoholism

This review of controlled studies of marital and family therapy (MFT) in alcoholism treatment updates the earlier review by O'Farrell and Fals-Stewart (2003). We conclude that, when the alcoholic is unwilling to seek help, MFT is effective in helping the family cope better and motivating alcoholics to enter treatment. Specifically, both Al-Anon facilitation and referral and spouse coping skills training (based on new findings) help family members cope better, and CRAFT promotes treatment entry and was successfully transported to a community clinic in a new study. Once the alcoholic enters treatment, MFT, particularly behavioral couples therapy (BCT), is clearly more effective than individual treatment at increasing abstinence and improving relationship functioning. New BCT studies showed efficacy with women alcoholics and with gay and lesbian alcoholics, and BCT was successfully transported to a community clinic, a brief BCT version was tested, and BCT was adapted for family members other than spouses. Future studies should evaluate the following: MFT with couples where both members have a current alcohol problem and with minority patients, mechanisms of change, transportability of evidence-based MFT approaches to clinical practice settings, and replication of MFT outcomes of reduced partner violence and improved child functioning.     

Exposing Humanism: Prudence,Ingenium, and the Politics of the Posthuman

This article examines posthumanism and its relationship to humanism. First, it is argued that the term “posthumanism” relies upon an incomplete conception of humanism, and in a way that forecloses the possibility of looking to the humanist tradition for support. Addressing Foucault's often quoted comments about the recent invention and imminent demise of man, it is argued that Foucault is not anti‐humanist, but is rather critical of the use of humanism as an axis of reflection. Second, the posthumanist perspective is summarized as attending to a set of interrelated ethical and epistemological concerns. Calling into question the boundary between human and nonhuman animals, posthumanism also challenges the primacy of empirico‐deductive reasoning and advocates a re‐legitimization of rhetoric as a mode of thought. Lastly, using Ernesto Grassi's interpretation of the early Italian humanists, this article demonstrates not only the compatibility of Renaissance humanism with posthumanist concerns, but also the fruitfulness of this tradition as a conceptual resource. Although the Renaissance notion of ingenium, the ability to adapt and make concrete situations meaningful without also affirming strong ontological commitments, is absent from posthumanist discourse, it is a concept that has the power to enrich the posthumanist project. Consequently, posthumanism is not actually at odds with the humanist tradition in general, but rather only with a very limited and relatively recent conception.
