Evaluating academic and media nongovernmental organization partnerships for participatory data gathering

This article discusses participatory methods for data gathering in the context of a partnership between a Swiss-based media development organization, Fondation Hirondelle, and a research team at the University of Sheffield. In 2018–2019, the partnership conducted fieldwork which focused on the impact of radio on women listeners in Niger. The project used participatory methods of data gathering in the form of workshops and focus group discussions (FGDs). The article examines the advantages and limitations of combining the practical experience of international development organizations and the in-depth research capabilities of academia. To triangulate this collaboration and to navigate the limitations of FGDs, the use of workshops is discussed as an important method for providing feedback among the radio practitioners and experts in Niger. The article examines the usefulness of combining these methods and reshaping their application to promote participatory research with radio audiences and practitioners

Getting Acquainted with Kant

My question here concerns whether Kant claims that experience has nonconceptual content, or whether, on his view, experience is essentially conceptual. However there is a sense in which this debate concerning the content of intuition is ill-conceived. Part of this has to do with the terms in which the debate is set, and part to do with confusion over the connection between Kant’s own views and contemporary concerns in epistemology and the philosophy of mind. However, I think much of the substance of the debate concerning Kant’s views on the content of experience can be salvaged by reframing it in terms of a debate about the dependence relations, if any, that exist between different cognitive capacities. Below, in Section 2, I clarify the notion of ‘content’ I take to be at stake in the interpretive debate. Section 3 presents reasons for thinking that intuition cannot have content in the relevant sense. I then argue, in Section 4, that the debate be reframed in terms of dependence. We should distinguish between Intellectualism, according to which all objective representation (understood in a particular way) depends on acts of synthesis by the intellect, and Sensibilism, according to which at least some forms of objective representation are independent of any such acts (or the capacity for such acts). Finally, in Section 5, I further elucidate the cognitive role of intuition. I articulate a challenge which Kant understands alethic modal considerations to present for achieving cognition, and argue that a version of Sensibilism that construes intuition as a form of acquaintance is better positioned to answer this challenge than Intellectualism

Comedian Hosts and the Demotic Turn

Podcasting is a showcase for what cultural studies scholar Graeme Turner coined “the demotic turn” or the increasing visibility of the ordinary person in the today’s media landscape. Collins argues that the emergence of a particular breed of podcasts – comedian-hosted interviews with celebrities – function in an “off-label” manner as a form of self-help or vicarious therapy. The emergence and rapid growth of this genre can attributed to three main factors: a confessional culture, the triumph of experience over expertise, and the democratization allowed by the form’s technology. She explores the link between emotional intimacy and comedy, and analyzes podcasts like Marc Maron’s WTF that are, in expression, a rejection of the pedestal version of stardom

Evidentialism and Moral Encroachment

Moral encroachment holds that the epistemic justification of a belief can be affected by moral factors. If the belief might wrong a person or group more evidence is required to justify the belief. Moral encroachment thereby opposes evidentialism, and kindred views, which holds that epistemic justification is determined solely by factors pertaining to evidence and truth. In this essay I explain how beliefs such as ‘that woman is probably an administrative assistant’—based on the evidence that most women employees at the firm are administrative assistants—motivate moral encroachment. I then describe weaknesses of moral encroachment. Finally I explain how we can countenance the moral properties of such beliefs without endorsing moral encroachment, and I argue that the moral status of such beliefs cannot be evaluated independently from the understanding in which they are embedded

A synergistic antiproliferation effect of curcumin and docosahexaenoic acid in SK-BR-3 breast cancer cells: unique signaling not explained by the effects of either compound alone

<p>Abstract</p> <p>Background</p> <p>Breast cancer is a collection of diseases in which molecular phenotypes can act as both indicators and mediators of therapeutic strategy. Therefore, candidate therapeutics must be assessed in the context of multiple cell lines with known molecular phenotypes. Docosahexaenoic acid (DHA) and curcumin (CCM) are dietary compounds known to antagonize breast cancer cell proliferation. We report that these compounds in combination exert a variable antiproliferative effect across multiple breast cell lines, which is synergistic in SK-BR-3 cells and triggers cell signaling events not predicted by the activity of either compound alone.</p> <p>Methods</p> <p>Dose response curves for CCM and DHA were generated for five breast cell lines. Effects of the DHA+ CCM combination on cell proliferation were evaluated using varying concentrations, at a fixed ratio, of CCM and DHA based on their individual ED₅₀. Detection of synergy was performed using nonlinear regression of a sigmoid dose response model and Combination Index approaches. Cell molecular network responses were investigated through whole genome microarray analysis of transcript level changes. Gene expression results were validated by RT-PCR, and western blot analysis was performed for potential signaling mediators. Cellular curcumin uptake, with and without DHA, was analyzed via flow cytometry and HPLC.</p> <p>Results</p> <p>CCM+DHA had an antiproliferative effect in SK-BR-3, MDA-MB-231, MDA-MB-361, MCF7 and MCF10AT cells. The effect was synergistic for SK-BR-3 (ER^-PR^-Her2⁺) relative to the two compounds individually. A whole genome microarray approach was used to investigate changes in gene expression for the synergistic effects of CCM+DHA in SK-BR-3 cells lines. CCM+DHA triggered transcript-level responses, in disease-relevant functional categories, that were largely non-overlapping with changes caused by CCM or DHA individually. Genes involved in cell cycle arrest, apoptosis, inhibition of metastasis, and cell adhesion were upregulated, whereas genes involved in cancer development and progression, metastasis, and cell cycle progression were downregulated. Cellular pools of PPARγ and phospho-p53 were increased by CCM+DHA relative to either compound alone. DHA enhanced cellular uptake of CCM in SK-BR-3 cells without significantly enhancing CCM uptake in other cell lines.</p> <p>Conclusions</p> <p>The combination of DHA and CCM is potentially a dietary supplemental treatment for some breast cancers, likely dependent upon molecular phenotype. DHA enhancement of cellular curcumin uptake is one potential mechanism for observed synergy in SK-BR-3 cells; however, transcriptomic data show that the antiproliferation synergy accompanies many signaling events unique to the combined presence of the two compounds.</p

Modularity in Protein Complex and Drug Interactions Reveals New Polypharmacological Properties

Recent studies have highlighted the importance of interconnectivity in a large range of molecular and human disease-related systems. Network medicine has emerged as a new paradigm to deal with complex diseases. Connections between protein complexes and key diseases have been suggested for decades. However, it was not until recently that protein complexes were identified and classified in sufficient amounts to carry out a large-scale analysis of the human protein complex system. We here present the first systematic and comprehensive set of relationships between protein complexes and associated drugs and analyzed their topological features. The network structure is characterized by a high modularity, both in the bipartite graph and in its projections, indicating that its topology is highly distinct from a random network and that it contains a rich and heterogeneous internal modular structure. To unravel the relationships between modules of protein complexes, drugs and diseases, we investigated in depth the origins of this modular structure in examples of particular diseases. This analysis unveils new associations between diseases and protein complexes and highlights the potential role of polypharmacological drugs, which target multiple cellular functions to combat complex diseases driven by gain-of-function mutations

Characterization of the binding sites of the anticancer ruthenium(III) complexes KP1019 and KP1339 on human serum albumin via competition studies

Indazolium trans-[tetrachloridobis(1H-indazole)ruthenate(III)] (KP1019) and its Na+ analogue (KP1339) are two of the most prominent non-platinum antitumor metal complexes currently undergoing clinical trials. After intravenous administration, they are known to bind to human serum albumin (HSA) in a noncovalent manner. To elucidate their HSA binding sites, displacement reactions with the established site markers warfarin and dansylglycine as well as bilirubin were monitored by spectrofluorimetry, ultrafiltration-UV-vis spectrophotometry, and/or capillary zone electrophoresis. Conditional stability constants for the binding of KP1019 and KP1339 to sites I and II of HSA were determined, indicating that both Ru(III) compounds bind to both sites with moderately strong affinity (log K (1)' = 5.3-5.8). No preference for either binding site was found, and similar results were obtained for both metal complexes, demonstrating low influence of the counter ion on the binding event

Increasing female participation in municipal elections via the use of local radio in conflict-affected settings: The case of the West Bank municipal elections 2017

The 2017 West Bank Municipal elections were framed by locally-based non-governmental organisations (NGOs) and the Palestinian Authorities – albeit to a lesser extent – in terms of the desirability of increasing female participation in them in two particular ways: participation as representatives and participation as voters. Both aspects of participation were supported by extensive radio campaigns conducted by locally-based NGOs. The effectiveness of these campaigns and the approaches used form the basis of this article. Using a mixed methods approach consisting of both quantitative and qualitative data, it concludes that radio has endemic socio-technical advantages for reaching women, particularly in conflict-affected areas, and that broadcasting content aimed at women by women is essential in terms of increasing their representation and voting
