Post-doctoral research fellowship as a health policy and systems research capacity development intervention: a case of the CHESAI initiative

BACKGROUND: Building capacity in health policy and systems research (HPSR), especially in low- and middle-income countries, remains a challenge. Various approaches have been suggested and implemented by scholars and institutions using various forms of capacity building to address challenges regarding HPSR development. The Collaboration for Health Systems Analysis and Innovation (CHESAI) – a collaborative effort between the Universities of Cape Town and the Western Cape Schools of Public Health – has employed a non-research based post-doctoral research fellowship (PDRF) as a way of building African capacity in the field of HPSR by recruiting four post-docs. In this paper, we (the four post-docs) explore whether a PDRF is a useful approach for capacity building for the field of HPSR using our CHESAI PDRF experiences. METHODS: We used personal reflections of our written narratives providing detailed information regarding our engagement with CHESAI. The narratives were based on a question guide around our experiences through various activities and their impacts on our professional development. The data analysis process was highly iterative in nature, involving repeated meetings among the four post-docs to reflect, discuss and create themes that evolved from the discussions. RESULTS: The CHESAI PDRF provided multiple spaces for our engagement and capacity development in the field of HPSR. These spaces provided us with a wide range of learning experiences, including teaching and research, policy networking, skills for academic writing, engaging practitioners, co-production and community dialogue. Our reflections suggest that institutions providing PDRF such as this are valuable if they provide environments endowed with adequate resources, good leadership and spaces for innovation. Further, the PDRFs need to be grounded in a community of HPSR practice, and provide opportunities for the post-docs to gain an in-depth understanding of the broader theoretical and methodological underpinnings of the field. CONCLUSION: The study concludes that PDRF is a useful approach to capacity building in HPSR, but it needs be embedded in a community of practice for fellows to benefit. More academic institutions in Africa need to adopt innovative and flexible support for emerging leaders, researchers and practitioners to strengthen our health systemsIS

The centroid paradigm: Quantifying feature-based attention in terms of attention filters

This paper elaborates a recent conceptualization of feature-based attention in terms of attention filters (Drew et al., Journal of Vision, 10(10:20), 1-16, 2010) into a general purpose centroid-estimation paradigm for studying feature-based attention. An attention filter is a brain process, initiated by a participant in the context of a task requiring feature-based attention, which operates broadly across space to modulate the relative effectiveness with which different features in the retinal input influence performance. This paper describes an empirical method for quantitatively measuring attention filters. The method uses a "statistical summary representation" (SSR) task in which the participant strives to mouse-click the centroid of a briefly flashed cloud composed of items of different types (e.g., dots of different luminances or sizes), weighting some types of items more strongly than others. In different attention conditions, the target weights for different item types in the centroid task are varied. The actual weights exerted on the participant's responses by different item types in any given attention condition are derived by simple linear regression. Because, on each trial, the centroid paradigm obtains information about the relative effectiveness of all the features in the display, both target and distractor features, and because the participant's response is a continuous variable in each of two dimensions (versus a simple binary choice as in most previous paradigms), it is remarkably powerful. The number of trials required to estimate an attention filter is an order of magnitude fewer than the number required to investigate much simpler concepts in typical psychophysical attention paradigms

Exploring the borderlands of neuroscience and social science

The field of social cognitive affective neuroscience seems to overcome long-term problems undermining old-fashioned cognitive neuroscience, such as its reductionist approach; its exclusion of affect, body, and culture in the comprehension of mental phenomena; and its propensity towards isolationist models over integrative or multilevel theories of neurocognition. Moreover, in this developing field, centuries-old arguments of incommensurability between natural and human sciences can be reframed as little more than pseudoproblems. The apparent paradigm shift inherent in social cognitive neuroscience entails new conceptual, methodological, metatheoretical, and aesthetic questions. Also, it gives rise to novel problems as it taxes the boundaries with other disciplines. Many of these dynamical tensions among related fields of knowledge, which are often left implicit, continue to change across domains and periods. Here we chart such new borderlands and summarize the contributions comprised in the present book. Neuroscience and Social Science: The Missing Link engages empirical researchers and theorists around the world in an attempt to integrate perspectives from many disciplines it addresses, separating real from spurious divides between them, and delineating new challenges for future investigation. The volume is organized in four sections. Section A is devoted to neuroscientific research on specific domains of social cognition, ranging from social emotions, negotiation, and cooperation, interpersonal coordination, to empathy and morality. Section B focuses on the impact of social neuroscience in specific social spheres, namely: the clinical field, psychotherapeutic settings, and the mass media. Section C encompasses works on the integration of social and neuroscientific insights to contribute to matters as pressing as poverty, socioeconomic inequality, health and wellbeing. Finally, Section D offers philosophical contributions on theoretical, methodological, and even ethical questions arising from this promising interdisciplinary encounter. Through this wide-ranging proposal, the volume promotes novel reflections on a much-needed marriage while opening opportunities for social neuroscience to plunge from the laboratory into the core of social life.Fil: Ibanez Barassi, Agustin Mariano.

Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of culture on the situational and psychological factors affecting moral judgements. Thus, we empirically tested the universality of the effects of intent and personal force on moral dilemma judgements by replicating the experiments of Greene et al. in 45 countries from all inhabited continents. We found that personal force and its interaction with intention exert influence on moral judgements in the US and Western cultural clusters, replicating and expanding the original findings. Moreover, the personal force effect was present in all cultural clusters, suggesting it is culturally universal. The evidence for the cultural universality of the interaction effect was inconclusive in the Eastern and Southern cultural clusters (depending on exclusion criteria). We found no strong association between collectivism/individualism and moral dilemma judgements
