The Time-Course for the Capture and Hold of Visuospatial Attention by Fearful and Happy Faces

Fearful faces both capture our attention and hold it. However, little is known about the time-course for the capture and hold of spatial attention by fearful, and other emotional, faces. In three dot-probe studies we examined this time-course. Experiments 1 and 2 used fearful and neutral faces. In Experiment 1, dot-probe targets occurred 133, 266, and 532 ms post-face onset and in Experiment 2, dot-probe targets occurred 84, 168, 336, and 672 ms post-face onset. In Experiment 1, for both 133 and 266 ms conditions, reaction times were fastest for congruent trials and slowest for incongruent trials with reaction times for baseline trials falling between the two. The same pattern was found for the 84 and 168 ms conditions in Experiment 2. For the later time-points in both experiments there were no significant differences between conditions. To examine whether this time-course is unique to fearful faces, a third dot-probe experiment using time-points identical to Experiment 2 was conducted with happy and neutral faces. The results from Experiment 3 suggest that happy faces captured and held attention in the 168 and 336 ms conditions. Together, the results indicate that attention is captured and held by fearful faces at times earlier than approximately 300 ms, while happy faces also captured and held attention, but on a slightly different time-course from 168 to 336 ms.     

Organizational learning and knowledge in public service organizations: A systematic review of the literature

This paper is a systematic review of the literature on organizational learning and knowledge with relevance to public service organizations. Organizational learning and knowledge are important to public sector organizations, which share complex external challenges with private organizations, but have different drivers and goals for knowledge. The evidence shows that the concepts of organizational learning and knowledge are under-researched in relation to the public sector and, importantly, this raises wider questions about the extent to which context is taken into consideration in terms of learning and knowledge more generally across all sectors. A dynamic model of organizational learning within and across organizational boundaries is developed that depends on four sets of factors: features of the source organization; features of the recipient organization; the characteristics of the relationship between organizations; and the environmental context. The review concludes, first, that defining 'organization' is an important element of understanding organizational learning and knowledge. Second, public organizations constitute an important, distinctive context for the study of organizational learning and knowledge. Third, there continues to be an over-reliance on the private sector as the principal source of theoretical understanding and empirical research and this is conceptually limiting for the understanding of organizational learning and knowledge. Fourth, differences as well as similarities between organizational sectors require conceptualization and research that acknowledge sector-specific aims, values and structures. Finally, it is concluded that frameworks for explaining processes of organizational learning at different levels need to be sufficiently dynamic and complex to accommodate public organizations.     

COMMUNICATING THREAT: The Canadian State and Terrorism

Canada's position vis‐à‐vis September 11 differs substantially from the United States’ in both circumstance and rhetoric. Although Canada was not the target of the terrorist attack, the United States is Canada's closest neighbor. In the words of the Prime Minister in the weeks following September 11, the United States is “more like family than friends.” Given this, how has the terrorist threat been interpreted for and communicated to the public by the Canadian state? Through ethnographic content analyses of the documents (speeches and press releases) found on the Prime Minister's Office (PMO) Web site, we consider the communications by the Canadian state with respect to the events of September 11. We analyze this information within the overarching frameworks of risk and trust. In terms of risk, we examine the Prime Minister's communications and the framing of this communication as it relates to the discourse of probable harm and/or benefit. As for trust, we consider the emphasis on reputation and how this affects the information provided and its delivery. These risk/trust underpinnings speak to the Canadian state's construction of security, security threats, and the construction of the Canadian state more generally.     

Growing up Without Status: The Integration of Children in Mixed‐Status Families

Over the past three decades, a central new challenge confronting millions of children of immigrants has emerged: growing up in a mixed‐status family in which at least one member lacks legal authorization to live and work in the United States. A body of recent research argues that unauthorized immigrant status is the fundamental determinant of integration for unauthorized immigrants, with intergenerational consequences for their U.S.‐born children. We discuss the immigration and other policies that create the particular social context within which unauthorized immigration status becomes so detrimental for integration. Specifically, we focus on federal and state policies that undermine the very factors thought to protect children and support the integration of new generations of Americans: families and social networks, economic resources and opportunities, and health. We conclude with recommendations for future research.     

Social network resources and management of hypertension

Hypertension is one of the most prevalent chronic diseases among older adults, but rates of blood pressure control are low. In this article, we explore the role of social network ties and network-based resources (e.g., information and support) in hypertension diagnosis and management. We use data from the National Social Life, Health, and Aging Project to identify older adults with undiagnosed or uncontrolled hypertension. We find that network characteristics and emotional support are associated with hypertension diagnosis and control. Importantly, the risks of undiagnosed and uncontrolled hypertension are lower among those with larger social networks-if they discuss health issues with their network members. When these lines of communication are closed, network size is associated with greater risk for undiagnosed and uncontrolled hypertension. Health care utilization partially mediates associations with diagnosis, but the benefits of network resources for hypertension control do not seem to stem from health-related behaviors.     

An organizational model to distinguish between and integrate research and evaluation activities in a theory based evaluation

Theory-based evaluation (TBE) is an evaluation method that shows how a program will work under certain conditions and has been supported as a viable, evidence-based option in cases where randomized trials or high-quality quasi-experiments are not feasible. Despite the model's widely accepted theoretical appeal there are few examples of its well-implemented use, probably due to time and money limitations necessary for planning and a confusion over the definitions between research and evaluation functions and roles. In this paper, we describe the development of a theory-based evaluation design in a Math and Science Partnership (MSP) research project funded by the U.S. National Science Foundation (NSF). Through this work we developed an organizational model distinguishing between and integrating evaluation and research functions, explicating personnel roles and responsibilities, and highlighting connections between research and evaluation work. Although the research and evaluation components operated on independent budgeting, staffing, and implementation activities, we were able to combine datasets across activities to allow us to assess the integrity of the program theory, not just the hypothesized connections within it. This model has since been used for proposal development and has been invaluable as it creates a research and evaluation plan that is seamless from the beginning.     

Sociological Theories of Low-Wage Work

This review addresses the use of sociological theories in the examination of low-wage work. Due to the vast volume of literature on this topic, only theories that help to explain the dynamics of low-wage work are described, along with the differences and controversies surrounding these theories. These theories are divided into four topic areas related to theories of work, racial and gender theories, immigration theories, and intersectionality theory. The theories of work include different models of wage determination, namely, functional, conflict, and structural models. The review concludes with a conceptual map that illustrates how these theories can inform and guide practice.     

Polyvictimization in later life: Trauma-informed best practices

ABSTRACT

This article provides a summary of salient trauma findings and conveys the dearth of research pertaining specifically to the trauma of elder abuse. This material, in conjunction with information contained in other articles composing this special issue, lays the foundation for advancing a trauma-informed approach to assisting older adults who have experienced polyvictimization. Informed by the findings presented and their extensive clinical experience with victims of violence, the authors suggest steps for providing a trauma-informed and victim-centered response to older adults who have suffered polyvictimization. These steps are then illustrated with an in-depth late-life polyvictimization case analysis.
