Why the economic conception of human behabiour might lack a biological basis

In several recent papers Arthur Robson sketches evolutionary scenarios in order to explain why we humans evolved hard-wired utility functions and the capacity to choose flexibly on the basis of them. These scenarios are scrutinized minutely in the paper. It is pointed out that Robson ignores several relevant insightful ideas and distinctions that have surfaced in other contemporary evolutionary theorizing. A somewhat different picture of human behavior emerges once these ideas and distinctions are taken seriously

The spider does not always win the fight for attention: Disengagement from threat is modulated by goal set

Stimulus-driven preferential attention to threat can be modulated by goal-driven attention. However, it remains unclear how this goal-driven modulation affects specific attentional components implied in threat interference. We hypothesise that goal-driven modulation most strongly impacts delayed disengagement from threat. A spatial cueing task was used that disentangles delayed disengagement from attentional capture by tightly manipulating the locus of attention at the time of target onset. Different top-down goals were induced by instructing participants to identify bird/fish targets (Experiment 1) or spider/cat targets (Experiment 2) among animal non-targets. Delayed disengagement from a non-target spider was observed only when the spider was part of the target set, not when it was task-irrelevant. This corroborates evidence that threat stimuli do not necessarily override goal-driven attentional control and that extended processing of threatening distractors is not obligatory

MICRO-Foundations in Strategic Management: Squaring Coleman's Diagram

Abell, Felin and Foss argue that "macro-explanations" in strategic management, explanations in which organizational routines figure prominently and in which both the explanandum and explanans are at the macro-level, are necessarily incomplete. They take a diagram (which has the form of a trapezoid) from Coleman, Foundations of Social Theory, The Belknap Press of Harvard University Press, Cambridge (Mass.)/London, (1990) to task to show that causal chains connecting two macro-phenomena always involve "macro-to-micro" and "micro-to-macro" links, links that macro-explanations allegedly fail to recognize. Their plea for micro-foundations in strategic management is meant to shed light on these "missing links". The paper argues that while there are good reasons for providing micro-foundations, Abell, Felin and Foss's causal incompleteness argument is not one of them. Their argument does not sufficiently distinguish between causal and constitutive relations. Once these relations are carefully distinguished, it follows that Coleman's diagram has to be squared. This in turn allows us to see that macro-explanations need not be incomplete

Social Media, Professional Media, and Mobilization in Contemporary Britain:Explaining the Strengths and Weaknesses of the Citizens’ Movement 38 Degrees

This article was published in the journal Political Studies [SAGE © The Author(s)] and the definitive version is available at: https://doi.org/10.1177/0032321716631350Digital media continue to reshape political activism in unexpected ways. Within a period of a few years, the internet-enabled UK citizens’ movement 38 Degrees has amassed a membership of 3 million and now sits alongside similar entities such as America’s MoveOn, Australia’s GetUp! and the transnational movement Avaaz. In this article, we contribute to current thinking about digital media and mobilisation by addressing some of the limitations of existing research on these movements and on digital activism more generally. We show how 38 Degrees’ digital network repertoires coexist interdependently with its strategy of gaining professional news media coverage. We explain how the oscillations between choreographic leadership and member influence and between digital media horizontalism and elite media-centric work constitute the space of interdependencies in which 38 Degrees acts. These delicately balanced relations can quickly dissolve and be replaced by simpler relations of dependence on professional media. Yet despite its fragility, we theorise about how 38 Degrees may boost individuals’ political efficacy, irrespective of the outcome of individual campaigns. Our conceptual framework can be used to guide research on similar movements

Genome-wide meta-analysis for Alzheimer's disease cerebrospinal fluid biomarkers

Amyloid-beta 42 (A?42) and phosphorylated tau (pTau) levels in cerebrospinal fluid (CSF) reflect core features of the pathogenesis of Alzheimer's disease (AD) more directly than clinical diagnosis. Initiated by the European Alzheimer & Dementia Biobank (EADB), the largest collaborative effort on genetics underlying CSF biomarkers was established, including 31 cohorts with a total of 13,116 individuals (discovery n = 8074; replication n = 5042 individuals). Besides the APOE locus, novel associations with two other well-established AD risk loci were observed; CR1 was shown a locus for A?42 and BIN1 for pTau. GMNC and C16orf95 were further identified as loci for pTau, of which the latter is novel. Clustering methods exploring the influence of all known AD risk loci on the CSF protein levels, revealed 4 biological categories suggesting multiple A?42 and pTau related biological pathways involved in the etiology of AD. In functional follow-up analyses, GMNC and C16orf95 both associated with lateral ventricular volume, implying an overlap in genetic etiology for tau levels and brain ventricular volume

Threat captures attention, but not automatically: Top-down goals modulate attentional orienting to threat distractors

The rapid orienting of attention to potential threats has been proposed to proceed outside of top-down control. However, paradigms that have been used to investigate this have struggled to separate the rapid orienting of attention (i.e. capture) from the later disengagement of focal attention that may be subject to top-down control. Consequently, it remains unclear whether and to what extent orienting to threat is contingent on top-down goals. The current study manipulated the goal-relevance of threat distractors (spiders), whilst a strict top-down attentional set was encouraged by presenting the saliently colored target and the threat distracter simultaneously for a limited time. The goal-relevance of threatening distractors was manipulated by including a spider amongst the possible target stimuli (Experiment 1: spider/cat targets) or excluding it (Experiment 2: bird/fish targets). Orienting and disengagement were disentangled by cueing attention away from or towards the threat prior to its onset. The results indicated that the threatening spider distractors elicited rapid orienting of attention when spiders were potentially goal-relevant (Experiment 1) but did so much less when they were irrelevant to the task goal (Experiment 2). Delayed disengagement from the threat distractors was even more strongly contingent on the task goal and occurred only when a spider was a possible target. These results highlight the role of top-down goals in attentional orienting to and disengagement from threat. © 2016 The Psychonomic Society, Inc

From her story, to our story: Digital storytelling as public engagement around abortion rights advocacy in Ireland

Despite the divisive nature of abortion within the Republic of Ireland and Northern Ireland, where access to safe, legal abortion is severely restricted, effecting legislative reform demands widespread public support. In light of a building pro-choice counter-voice, this work contributes to a growing body of HCI research that takes an activist approach to design. We report findings from four design workshops with 31 pro-choice stakeholders across Ireland in which we positioned an exploratory protosite, HerStoryTold, to engender critical conversations around the use of sensitive abortion narratives as a tool for engagement. Our analysis shows how digital storytelling can help reject false narratives and raise awareness of the realities of abortion laws. It suggests design directions to curate narratives that provoke empathy, foster polyvocality, and ultimately expand the engaged community. Furthermore, this research calls for designers to actively support community mobilization through providing 'stepping stones' to activism
