Recognizing Emotions in a Foreign Language

Expressions of basic emotions (joy, sadness, anger, fear, disgust) can be recognized pan-culturally from the face and it is assumed that these emotions can be recognized from a speaker’s voice, regardless of an individual’s culture or linguistic ability. Here, we compared how monolingual speakers of Argentine Spanish recognize basic emotions from pseudo-utterances (“nonsense speech”) produced in their native language and in three foreign languages (English, German, Arabic). Results indicated that vocal expressions of basic emotions could be decoded in each language condition at accuracy levels exceeding chance, although Spanish listeners performed significantly better overall in their native language (“in-group advantage”). Our findings argue that the ability to understand vocally-expressed emotions in speech is partly independent of linguistic ability and involves universal principles, although this ability is also shaped by linguistic and cultural variables.

Social complexity and strong democracy

The pluralistic liberal paradigm of democracy has shown its inability to guarantee economic prosperity and political stability and, as a consequence, has become increasingly vulnerable. Within political theory, democratic criticism of liberalism has mainly proceeded along two paths. On the one hand, communitarians have challenged liberal atomism and sought to rehabilitate the community as the focus for social life and human personality. On the other hand, ‘strong’ democrats have rejected the political division of labour characteristic of liberalism and sought to revive the ideal of participatory democracy. There are many points of contact between these two strands of thought—indeed some influential writers have explicitly subscribed to both—and radical communitarianism has had an important influence in practical politics over the past 15 years. However their fundamental theoretical assumptions clash, in particular because strong democracy has an implicit bias towards social uniformity that contradicts the essential premise of communitarianism. The most straightforward way out of this problem is multiculturalism, i.e. the conception of society as a liberal federation of strong communities. How much scope this leaves for true democracy is however unclear.     

Recognizing majority-rule equilibrium in spatial voting games

It is provably difficult (NP-complete) to determine whether a given point can be defeated in a majority-rule spatial voting game. Nevertheless, one can easily generate a point with the property that if any point cannot be defeated, then this point cannot be defeated. Our results suggest that majority-rule equilibrium can exist as a purely practical matter: when the number of voters and the dimension of the policy space are both large, it can be too difficult to find an alternative to defeat the status quo. It is also computationally difficult to determine the radius of the yolk or the Nakamura number of a weighted voting game.We are grateful to Norman Schofield and an anonymous referee for many helpful suggestions.The first author was supported in part by a Presidential Young Investigator Award from the National Science Foundation (ECS-8351313) and by the Office of Naval Research (N00014-85-K-0147).

The complexity of ignorance

We examine the kinds of mistakes that are frequently made when the general public is asked to identify political symbols from the past half century. A particularly striking phenomenon is inversion: the event is recalled backwards, so that Rosa Parks is remembered for having given up her seat on a bus to a white person. A second type of error occurs by linking a name to the wrong person, as when John Dean is identified as a movie actor (James Dean). Still another type of mistake involves a correct substantive categorization but with temporal displacement, for example, the Tet Offensive is said to have occurred during the Korean War. In each of these cases we are able to speculate about the social and psychological processes that have led to the misremembering. However, not every error is lodged in respondents: we initially treated as incorrect all answers that did not fit our own expectations; but we were soon forced to recognize that other frames of reference could be brought to the task and lay equal claim to the truth. Names are alphabetical and authorship is equal.     

Role similarity and complexity in social networks

A new concept of role similarity is presented; this definition is a generalisation of structural equivalence but is stricter than the idea of regular equivalence of White and Reitz (1983). This new definition forms a standard part of graph theory literature and as such has been well researched. Consequently a complexity measure first proposed by Mowshowitz, 1968a, Mowshowitz, 1968b, Mowshowitz, 1968c can be given a definite meaning in terms of network concepts. A new measure of structural complexity based on role similarity is also introduced.     

认识房地产市场价格的角度与现实房地产问题

一、房地产市场的三大经济主体 房地产市场上活跃着相互作用的三类产权独立的经济主体,即家庭、企业和政府.家庭以买者(消费者)的身份,心怀不同预期(投资或消费)进入市场;企业以卖者(投资者)的身份,以获取最大利润(剩余价值)为目的进入市场;政府则以市场管理调控者的身份进入市场.家庭当期实际购买(一般为一年)的总和构成住房市场的总需求;当期建成房屋为住房市场的总供给(不需要实际卖出);而政府一般不能允许房地产市场价格的年增长率超过10%,更不能容忍因此而引发的社会问题.     

The authority of complexity*

The assertion about the unique 'complexity' or the peculiarly intricate character of social phenomena has, at least within sociology, a long, venerable and virtually uncontested tradition. At the turn of the last century, classical social theorists, for example, Georg Simmel and Emile Durkheim, made prominent and repeated reference to this attribute of the subject matter of sociology and the degree to which it complicates, even inhibits the develop and application of social scientific knowledge. Our paper explores the origins, the basis and the consequences of this assertion and asks in particular whether the classic complexity assertion still deserves to be invoked in analyses that ask about the production and the utilization of social scientific knowledge in modern society. We present John Maynard Keynes' economic theory and its practical applications as an illustration. We conclude that the practical value of social scientific knowledge is not dependent on a faithful, in the sense of complete, representation of social reality. Instead, social scientific knowledge that wants to optimize its practicality has to attend and attach itself to elements of social situations that can be altered or are actionable.     

Cognitive complexity of evaluator competencies

A critical aspect of evaluator education and professional learning is to educate evaluators who know the major evaluation models and learn how to manage relationships and solve complex problems when conducting, critiquing, developing and interpreting evaluations. The American and Australian Evaluation Associations have specified desired evaluator competencies, although developing a core curriculum for evaluation still seems elusive. It is suggested that these various competencies can be considered in terms of their levels of cognitive complexity.A model of cognitive complexity is utilised to explore the tasks and thinking of evaluators, leading to an important distinction between ‘knowing that’ and ‘knowing how’ in relation to evaluation tasks. As an illustration of this posited relationship, the Australian ‘Evaluators Professional Learning Competencies’ were coded according to their cognitive complexity. Two-thirds of these competencies were classed as ‘knowing that’ or surface thinking, and one third were classified as ‘knowing how’ or deeper thinking. A taxonomy is offered as a method to understand models of learning necessary for evaluator education and training, as well as for further development of professional evaluator competencies.
