The recognition of acted interpersonal stance in police interrogations and the influence of actor proficiency

This paper reports on judgement studies regarding the perception of interpersonal stances taken by humans playing the role of a suspect in a police interrogation setting. Our project aims at building believable embodied conversational characters to play the role of suspects in a serious game for learning interrogation strategies. The main question we ask is: do human judges agree on the way they perceive the various aspects of stance taking, such as friendliness and dominance? Four types of stances were acted by eight amateur actors. Short recordings were shown in an online survey to subjects who were asked to describe them using a selection of a number of adjectives. Results of this annotation task are reported in this paper. We explain how we computed the inter-rater agreement with Krippendorff’s alpha statistics using a set theoretical distance metric. Results show that for some of the stance types observers agreed more than for others. Some actors are better than others, but validity (recognizing the intended stance) and inter-rater agreement do not always go hand in hand. We further investigate the effect the expertise of actors has on the perception of the stance that is acted. We compare the fragments from amateur actors to fragments from professional actors taken from popular TV-shows

Exploring Policies of Spirituality among College Students

Though psychologists\u27 interest in the empirical study of spirituality has resurfaced, diverging opinions regarding the meaning of the construct among both researchers and the general public pose a serious challenge to research. To expand knowledge regarding how individuals implicitly define the term, an idiographic, experimental approach called policy-capturing was utilized to determine what factors college students take into consideration when making determinations about others\u27 spirituality. Participants were exposed to a series of 50 profiles describing hypothetical people, each of which contained a unique combination of different levels of five factors believed to characterize spirituality by researchers. Participants rated each profile to indicate degree of perceived spirituality. Regression analyses were utilized to reveal if individuals used the factors in a consistent manner when rating the profiles, as well as the relative importance of each factor in their policies of spirituality. Results indicated that consistency of policies and the importance placed on individual factors varied widely. No differences were found between more religious and less religious college students with regard to ratings of spirituality assigned to the profiles, consistency of policies of spirituality, the relative importance of any of the five spirituality factors, or the number of factors that were important in the policies. Findings support the idiosyncratic nature of the meanings attributed to spirituality, but call into question whether college students are consistently using the same definitional models of the construct as used by researchers. The discussion highlights the conceptual challenges that researchers of spirituality face and encourages the use of varied methods for continued investigation in this area

A case against school effectiveness

This paper considers the model of school effectiveness (SE) currently dominant in research, policy and practice in England (although the concerns it raises are international). It shows, principally through consideration of initial and propagated error, that SE results cannot be relied upon. By considering the residual difference between the predicted and obtained score for all pupils in any phase of education, SE calculations leave the results to be disproportionately made up of relative error terms. Adding contextual information confuses but does not help this situation. Having shown and illustrated the sensitivity of SE to this propagation of initial errors, and therefore why it is unworkable, the paper considers some of the reasons why SE has become dominant, outlines the damage this dominant model causes, and begins to shape alternative ways of considering what schools do

Entrepreneurship and Team Participation: An Experimental Study

Entrepreneurs are surprisingly unlikely to have partners. In spite of the obvious advantages to forming partnerships, only a small minority of entrepreneurs (less than 10%, excluding family businesses) have partners. A number of possible explanations exist for this puzzling phenomenon, including an inability to locate suitable partners, fear of free-riding by partners, and a preference for not working in groups. Utilizing a diverse subject population with a high proportion of active entrepreneurs, we use a team production experiment to study whether entrepreneurs prefer to work alone or in a team. The data indicate that entrepreneurs, while no more likely to free-ride on their teammates, are substantially less interested in joining teams. This suggests that efforts to encourage partnership among entrepreneurs may run contrary to the preferences of this group.Entrepreneurship, Teams, Artefactual Field Experiment
