In low-information elections, voters are likely to rely on heuristics when choosing candidates. Based on survey experiments conducted prior to Brazil's 2012 municipal elections, I examine the effect of candidates' professional titles, such as "doctor" and "pastor," on voting behavior. Using the "pastor" title in one's electoral name tends to decrease vote intention, although evangelical Christians respond positively while members of other religious groups are repelled. The broader at-mosphere of political competition between Brazilian evangelicals and Catholics helps explain the presence of both out-group and in-group cueing effects. The "doctor" title has a positive effect on vote intention that appears to be mediated by the positive stereotypes, such as intelligence and competence, associated with members of this profession.

This article argues for the value of working with conflicts in social practice as resources for collaboration, learning and development. The interest in conflicts in social practice is rooted in a preoccupation with social power relations and how to understand and analyse power relations from a subject-science perspective. Following this interest, a methodological framework, best described as a kind of 'mobile ethnography', is discussed and exemplified through an empirical example. A preliminary conceptual framework for understanding power as a capacity for action is presented. The overarching ambition of the article is to consider what democratic collaboration and coexistence entails and how it might be supported conceptually and analytically by the notion of conflicts as heuristics for social inquiry and by the notion of power as a capacity for action and social participation.

We examine heuristic decision rules in consumer choice on health insurance exchanges using data from the Massachusetts Connector. Consumers may have difficulty making optimal choices in a complex environment. The heuristic "choose the cheapest plan" is suggested by the decision context, previous research, and the data: about 20% of enrollees choose the cheapest plan possible. We find evidence of this heuristic in many models, but while heuristics may play a role, preference heterogeneity is also important. Our most flexible models find an insignificant heuristic effect. In part because holding context fixed, this heuristic is observationally equivalent to extreme price sensitivity.

AbstractThis article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

People decide on political issues using judgmental shortcuts called heuristics. What is the origin of these political heuristics? Traditionally, heuristics have been viewed as learned from the structure of elite debates. This article outlines a different view: that many political heuristics are evolved, biological adaptations that helped our ancestors deal with political problems in small-scale social groups. By analyzing these evolved origins, it becomes possible to develop novel, testable predictions regarding the structure of political heuristics. This argument is illustrated through an extensive review of studies on the structure of the so-called 'deservingness' heuristic. The article concludes by outlining four principles that should guide future research on heuristics in political psychology. Adapted from the source document.

"This enlightening book comprehensively maps the current state of economic psychology and behavioural economics. Exploring key concepts, topics and models in the field, it is also a launching pad for future research, providing useful insights on how to make good personal and professional decisions, advancing microeconomic discourse. The book lays out how economic decisions are made by answering key questions in the bordering field between economics and psychology. Close to the ecological rationality research program, it presents the main factors that determine economic choices, before exploring the most common algorithms used to concretize economic decisions and the main strategies for altering preferences. Chapters focus on the general issues surrounding economic choices, such as preferences, beliefs and emotions, and on the heuristic algorithms applied by people in decision-making processes, among which there are outstanding social concerns. Drawing these elements together, the author presents a seminal model combining preferences and heuristics to explain choices in the consumption of goods and services. This book will be an invaluable resource for academic and professional economists seeking to deepen their understanding of the psychological dimension of economic decisions. It will also be a useful guide for students of economics, management and the wider social sciences curious about decision-making procedures"--

AbstractFeminist philosophers have discussed the prospects for assessing values empirically, particularly given the ongoing threat of sexism and other oppressive values influencing science and society. Some advocates of such tests now champion a "values as evidence" approach, and they criticize Helen Longino's contextual empiricism for not holding values to the same level of empirical scrutiny as other claims. In this paper, we defend contextual empiricism by arguing that many of these criticisms are based on mischaracterizations of Longino's position, overstatements of certain claims, and false dichotomies. Her contextual empiricism not only allows for the empirical support and disconfirmation of values, but Longino explicitly discusses when values can be empirically adjudicated and emphasizes the crucial role of the community for standards of evidence. We support contextual empiricism and elaborate a less direct account of "values as heuristics" by reviewing Longino's theory of evidence and then using a case study from Elisabeth Lloyd on the biology of female orgasm, demonstrating the disconfirmation of androcentric values in evolutionary science. Within Longino's and Lloyd's contextual empiricism, values do not get treated as empirical evidence to be directly assessed by individuals, but rather values are heuristic tools to build models whose use can be validated or invalidated by communities based on their empirical fruitfulness in the logic and pragmatics of research questions in specific historical and cultural contexts.

117 128 40 1 ; S ; [EN] In recent years, a large number of heuristics have been proposed for the minimization of the total or mean flowtime/completion time of the well-known permutation flowshop scheduling problem. Although some literature reviews and comparisons have been made, they do not include the latest available heuristics and results are hard to compare as no common benchmarks and computing platforms have been employed. Furthermore, existing partial comparisons lack the application of powerful statistical tools. The result is that it is not clear which heuristics, especially among the recent ones, are the best. This paper presents a comprehensive review and computational evaluation as well as a statistical assessment of 22 existing heuristics. From the knowledge obtained after such a detailed comparison, five new heuristics are presented. Careful designs of experiments and analyses of variance (ANOVA) techniques are applied to guarantee sound conclusions. The comparison results identify the best existing methods and show that the five newly presented heuristics are competitive or better than the best performing ones in the literature for the permutation flowshop problem with the total completion time criterion This research is partially supported by National Science Foundation of China (60874075, 61174187), and Science Foundation of Shandong Province, China (BS2010DX005), and Postdoctoral Science Foundation of China (20100480897).

The article deals with the heuristic potential of the sociological theory by Giovanni Arrighi in the study of the dynamic aspect of the formation and maintenance of global inequality systems. To achieve the goal – to analyze the applicability of the dynamic aspect of the theory to study the mentioned topic – the changes of systemic cycles of accumulation and hegemony is analyzed. Special attention is paid to transitional points in which a hegemony crisis occurs and one cycle is being replaced by another, after which one can observe the hegemony transit. The cases (Genoa, Amsterdam, United Kingdom, USA) that Giovanni Arrighi selects to illustrate the cyclical nature of the historical development of world capitalism and the financialization character of these processes are being considered. The article studies the method of how G. Arrighi applies the Marxian formula of capital accumulation (M-C-M') to the description of the mechanism for changing accumulation cycles; its potential for studying this process is analyzed. The distinctive features of the development process of accumulation cycles are studied: movement towards the formation of a stronger cosmopolitan empire, historical and geographical conditionality, double movement forward and backward. In the final part, possible vectors of the future development of the world order and the formation of new global inequality systems according to G. Arrighi's vision are examined. Particular attention is paid to the role of transnational corporations in the expansion of world capitalism. The result of the work is a critical analysis of G. Arrighi's theory, which determines the strengths and weaknesses in the study of a chosen subject, and also identifies potential areas for further research. An attempt is made to apply the dynamic aspect of the concept to explain the nature and functions of global systems of inequality.
