Theory and Decision - In a three-candidate election, a scoring rule λ, λ∈[0,1], assigns 1,λ and 0 points (respectively) to each first, second and third place in the individual...     

Interpretations of Child Emotion Expressions and Coercive Parenting Practices Among Adolescent Mothers

This study examined the relation between adolescent mothers' interpretations of various child emotion expressions and coercive parenting practices (n = 4 mother-child dyads, child ages = 10–34 mos.). The more coercive mothers decoded a range of child emotion expressions as exhibiting greater anger, and attributed greater defiant intentions to the child, compared to less coercive mothers. The findings for attributions of defiance were robust, as they were independent of both emotion decoding and level of child difficulty. Findings are discussed with regard to (a) mothers' basic assumptions about the child; (b) the robust character of attributions of defiance in relation to coercive parenting; (c) the potential implications of this study for research with adult mothers; and (d) investigation of temporal precedence and developmental pathways in the interrelations among child behavior, maternal cognition, and parenting behavior.     

Do Infants Recognize Engagement in Social Interactions? The Case of Face‐to‐Face Conversation

This study explores 12‐month‐olds' understanding of face‐to‐face conversation, a key contextual structure associated with engagement in a social interaction. Using a violation‐of‐expectations paradigm, we habituated infants to a “face‐to‐face” conversation, and in a test phase compared their looking times between “back‐to‐back” (conceptually novel) and “face‐to‐face” (conceptually familiar) conversations, while simultaneously manipulating perceptual familiarity in a 2 × 2 factorial design. We also analyzed dynamic changes in pupil dilation, which are considered a reliable measure of cognitive load that may index processing of social interactions. Infants looked relatively longer at perceptual changes (new speaker positions) but not at conceptual change (back‐to‐back conversation), suggesting that face‐to‐face conversation may not elicit particular expectations, and so may not carry any particular conceptual significance. Moreover, on the first test trial, larger pupil dilation was observed for familiar conditions, suggesting that familiarity with perceptual features could enhance processing of conversations. Thus, this study undermines assertions regarding infants' conceptual understanding of the social signals underlying engagement. Infants may rather recognize such signals through their perceptual familiarity and associated positive feelings. This may then increase their engagement when observing and participating in others' collaborative activities, in turn allowing for the development of knowledge regarding others' intentions.     

Advances in the Conceptualization of Personality Disorders: Issues Affecting Social Work Practice and Research

This article provides a review of the research that has informed the proposed changes to the DSM-5 conceptualization of personality psychopathology with a focus on implications for social work practice and research. A paradigm shift to a dimensional model is likely to replace the current categorical model of personality disorders and will have profound implications for the profession. While establishing a diagnostic system that is grounded in empirical knowledge is the primary benefit, this tool will also be more consistent with social work’s orienting theories and values. Social workers should gain knowledge about the proposed changes and actively participate in the review process.     

Child welfare workers' practice in cases involving domestic violence

This paper reports the findings of an exploratory and qualitative study of child welfare workers' practice in cases involving domestic violence. The research aimed to focus on child welfare workers' interventions with families experiencing domestic violence, elements influencing the child welfare workers' decisions, and the factors facilitating and creating obstacles for intervention. An analysis of the qualitative data showed that child welfare workers have different ways of intervening in cases involving domestic violence. Also, the interventions were especially centred on women victims of violence and they were held responsible for protecting their children. Finally, the dilemmas and difficulties which child welfare workers face in these cases are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

The Unexpected Behavior of Plurality Rule

When voters’ preferences on candidates are mutually coherent, in the sense that they are at all close to being perfectly single-peaked, perfectly single-troughed, or perfectly polarized, there is a large probability that a Condorcet Winner exists in elections with a small number of candidates. Given this fact, the study develops representations for Condorcet Efficiency of plurality rule as a function of the proximity of voters’ preferences on candidates to being perfectly single-peaked, perfectly single-troughed or perfectly polarized. We find that the widely used plurality rule has Condorcet Efficiency values that behave in very different ways under each of these three models of mutual coherence.     

How do men with paraplegia choose activities in the light of striving for optimal participation? A qualitative study,based on a phenomenological–hermeneutical method

The objective of this study was to explore the experiences of men with paraplegia with regard to how they choose activities. The study involved a qualitative research design, based on a phenomenological–hermeneutical method. The findings revealed that the activities participants were choosing could be on a continuum between the individual’s self and the influence from their environment. On this continuum, the choice to perform activities was influenced by two mediating factors: the individual’s activities performed during their life-history, and their activity challenges for the future. We conclude that choosing activities is an individually constructed internal process of negotiation. Feelings of resignation and revolt appear in combination with feelings of justice and injustice when balance is not found. This knowledge provides a better understanding of the impact of spinal cord injury, sheds light on the development of distress after spinal cord injury and sheds new light on individuals’ feelings of participation.     

Interweaving Objects,Gestures, and Talk in Context

In a large French hospital, a group of professional experts (including physicians and software engineers) are working on the computerization of a blood-transfusion traceability device. By focusing on a particular moment in this slow process of design, we analyze their collaborative practices during a work session. The analysis takes a praxeological and interactionist approach and is inspired by discussions on the role of artifacts in social practices currently developed within various research frameworks in this field: activity theory, distributed cognition, conversation analysis, and actor network theory. After a brief presentation of the place of objects and artifacts in these ways of approaching action and human cognition, we show how the collective activity analyzed here is generated by the interweaving of discursive, gestural, and artifactual resources.
