Unresolved Problems with the "I", the "A" and the "T": Logical and Psychometric Critique of the Implicit Association Test (IAT)

The Implicit Association Test (IAT) had already gained the status of a prominent assessment procedure before its psychometric properties and underlying task structure were understood. The present critique addresses five major problems that arise when the IAT is used for diagnostic inferences: (1) the asymmetry of causal and diagnostic inferences; (2) the viability of the underlying association model; (3) the lack of a testable model underlying IAT-based inferences; (4) the difficulties of interpreting difference scores; and (5) the susceptibility of the IAT to deliberate faking and strategic processing. Based on a theoretical reflection of these issues, and a comprehensive survey of published IAT studies, it is concluded that a number of uncontrolled factors can produce (or reduce) significant IAT scores independently of the personality attribute that is supposed to be captured by the IAT procedure.

A Critique of Authenticity and Recognition

While forms of ethics based upon authenticity and recognition are holding sway in contemporary philosophical debates (Ferrara, Honneth, Fraser, etc.), many of the implications of both processes – conceptual, moral, political – are still insufficiently reflected upon. The talk will offer a “critique” (in the Kantian sense) of both, based upon an analysis of the “semiotics” of authenticity and the resulting perpetuation of a regime of authority of experts, as well as commenting upon the striking absence of the realm of literature and the arts from this debate, except in some references to a rather abstract notion of Aesthetics. It will also critically revaluate the concept of agency implicit in an ethics of authenticity and recognition.

Representation via Probabilities: Models of Probabilistic Modeling

How do probabilistic models represent their targets and how do they allow us to learn about them? The answer to this question depends on a number of details, in particular on the meaning of the probabilities involved. To classify the options, a minimalist conception of representation (Su\'arez 2004) is adopted: Modelers devise substitutes (``sources'') of their targets and investigate them to infer something about the target. Probabilistic models allow us to infer probabilities about the target from probabilities about the source. This leads to a framework in which we can systematically distinguish between different models of probabilistic modeling. I develop a fully Bayesian view of probabilistic modeling, but I argue that, as an alternative, Bayesian degrees of belief about the target may be derived from ontic probabilities about the source. Remarkably, some accounts of ontic probabilities can avoid problems if they are supposed to apply to sources only.

Mind the gap: Do proportional electoral systems foster a more equal representation of women and men, poor and rich?

Female gender and low income are two markers for groups that have been historically disadvantaged within most societies. The study explores two research questions related to their political representation: (1) ‘Are parties biased towards the ideological preferences of male and rich citizens?’; and (2) ‘Does the proportionality of the electoral system moderate the degree of under-representation of women and poor citizens in the party system?’ A multilevel analysis of survey data from 24 parliamentary democracies indicates that there is some bias against those with low income and, at a much smaller rate, women. This has systemic consequences for the quality of representation, as the preferences of the complementary groups differ. The proportionality of the electoral system influences the degree of under-representation: specifically, larger district magnitudes help in closing the considerable gap between rich and poor.

Does culture really matter in sports participation? The impact of socio-cultural factors on sports behaviour in Switzerland

The physical activity of the Swiss population differs considerably depending on the linguistic region. German speakers are more often physically active than people living in the French or Italian-speaking part of Switzerland (Stamm & Lamprecht, 2011). This study analyses how socio-cultural factors correlate with sports participation for adolescents and young adults. In order to analyse this research question, Bourdieu’s concept of habitus (1984) has been adapted and used as a theoretical background. This sport-related concept of habitus considers culturally determined values, the attribution of meaning and patterns of action such as the understanding of sports, the importance of sports, body, health or leisure. On this basis, the sport-related habitus and the practical relevance of sports participation has been empirically reconstructed for adolescents and young adults aged 15 to 25 through a qualitative study including guideline-based interviews with German (n=6) and French (n=4) speaking adolescents and young adults, as well as a quantitative survey in a German (n=106) and a French (n=99) speaking commune of Switzerland. Initial findings reveal that young German speakers associate sports with self-discipline (χ²(1, N=205)= 8.223, p<.005, V=.200) and fitness (χ²(1, N=205)= 21.989, p<.005, V=.328) whereas young French speakers are more likely to relate health (χ²(1, N=205)= 9.455, p<.005, V=.215), effort and perspiration (χ²(1, N=205)= 18.835, p<.005, V=.303) to sports. Similarly, the understanding of body and health as well as the attitude towards leisure differs between the German and French speaking parts of Switzerland. This study illustrates that the concept of sports habitus is culturally shaped and therefore may be fruitful in further analyses. Bourdieu, P. (1984). Distinction.

The Power of Tolerance. A Debate

We invoke the ideal of tolerance in response to conflict, but what does it mean to answer conflict with a call for tolerance? Is tolerance a way of resolving conflicts or a means of sustaining them? Does it transform conflicts into productive tensions, or does it perpetuate underlying power relations? To what extent does tolerance hide its involvement with power and act as a form of depoliticization? Wendy Brown and Rainer Forst debate the uses and misuses of tolerance, an exchange that highlights the fundamental differences in their critical practice despite a number of political similarities. Both scholars address the normative premises, limits, and political implications of various conceptions of tolerance. Brown offers a genealogical critique of contemporary discourses on tolerance in Western liberal societies, focusing on their inherent ties to colonialism and imperialism, and Forst reconstructs an intellectual history of tolerance that attempts to redeem its political virtue in democratic societies. Brown and Forst work from different perspectives and traditions, yet they each remain wary of the subjection and abnegation embodied in toleration discourses, among other issues. The result is a dialogue rich in critical and conceptual reflections on power, justice, discourse, rationality, and identity.

Can the green economy enhance sustainable mountain development? The potential role of awareness building

Mountain socio-ecological systems produce valuable but complex ecosystem services resulting from biomes stratified by altitude and gravity. These systems are often managed and shaped by smallholders whose marginalization is exacerbated by uncertainties and a lack of policy attention. Human–environment interfaces in mountains hence require holistic policies. We analyse the potential of the Global Mountain Green Economy Agenda (GMGEA) in building awareness and thus prompting cross-sectoral policy strategies for sustainable mountain development. Considering the critique of the green economy presented at the Rio + 20 conference, we argue that the GMGEA can nevertheless structure knowledge and inform regional institutions about the complexity of mountain socio-ecological systems, a necessary pre-condition to prompt inter-agency collaboration and cross-sectoral policy formulation. After reviewing the content of the GMGEA, we draw on two empirical cases in the Pakistani and Nepali Himalayas. First, we show that lack of awareness has led to a sequence of fragmented interventions with unanticipated, and unwanted, consequences for communities. Second, using a green economy lens, we show how fragmentation could have been avoided and cross-sectoral policies yielded more beneficial results. Project fragmentation reflects disconnected or layered policies by government agencies, which inherently keep specialized agendas and have no incentive to collaborate. Awareness makes agencies more likely to collaborate and adopt cross-sectoral approaches, allowing them to target more beneficiaries, be more visible, and raise more funds. Nevertheless, we also identify four factors that may currently still limit the effect of the GMGEA: high costs of inter-agency collaboration, lack of legitimacy of the green economy, insufficiently-secured smallholder participation, and limited understanding of the mechanisms through which global agendas influence local policy.

Sensitivity of the WRF model to PBL parametrisations and nesting techniques: evaluation of wind storms over complex terrain

Simulating surface wind over complex terrain is a challenge in regional climate modelling. Therefore, this study aims at identifying a set-up of the Weather Research and Forecasting Model (WRF) model that minimises system- atic errors of surface winds in hindcast simulations. Major factors of the model configuration are tested to find a suitable set-up: the horizontal resolution, the planetary boundary layer (PBL) parameterisation scheme and the way the WRF is nested to the driving data set. Hence, a number of sensitivity simulations at a spatial resolution of 2 km are carried out and compared to observations. Given the importance of wind storms, the analysis is based on case studies of 24 historical wind storms that caused great economic damage in Switzerland. Each of these events is downscaled using eight different model set-ups, but sharing the same driving data set. The results show that the lack of representation of the unresolved topography leads to a general overestimation of wind speed in WRF. However, this bias can be substantially reduced by using a PBL scheme that explicitly considers the effects of non-resolved topography, which also improves the spatial structure of wind speed over Switzerland. The wind direction, although generally well reproduced, is not very sensitive to the PBL scheme. Further sensitivity tests include four types of nesting methods: nesting only at the boundaries of the outermost domain, analysis nudging, spectral nudging, and the so-called re-forecast method, where the simulation is frequently restarted. These simulations show that restricting the freedom of the model to develop large-scale disturbances slightly increases the temporal agreement with the observations, at the same time that it further reduces the overestimation of wind speed, especially for maximum wind peaks. The model performance is also evaluated in the outermost domains, where the resolution is coarser. The results demonstrate the important role of horizontal resolution, where the step from 6 to 2 km significantly improves model performance. In summary, the combination of a grid size of 2 km, the non-local PBL scheme modified to explicitly account for non-resolved orography, as well as analysis or spectral nudging, is a superior combination when dynamical downscaling is aimed at reproducing real wind fields.
