The research reported here is an analysis of the evolution of the relationships that comprise a single public health network, focusing especially on the position of the network administrative organization (Provan and Kenis 2008 Provan, K. G. and P. Kenis. 2008. “Modes of Network Governance: Structure, Management, and Effectiveness.” Journal of Public Administration Research and Theory 18(2): 229252.[Crossref], [Web of Science ®] [Google Scholar]) in the flow of knowledge among a large number of organizations providing similar services. Our study examines the North American Quitline Consortium (NAQC), a multi-sector network that spans the US and Canada and whose members provide telephone-based tobacco cessation services to anyone interested in quitting smoking. Data were collected using web-based surveys at three different points of time. Implications are discussed for network organizing, for both theory and practice, focusing especially on the importance of the network administrative organization in shaping the evolution of the whole network information flow.  相似文献

Many core graduate-level seminars claim to expose students to their discipline’s “canon.” The contents of this canon, however, can and do differ across departments and instructors. This project employs a survey of core American politics PhD seminar syllabi at highly ranked universities to construct a systematic account of the American politics canon. Our results offer valuable insights into the topics and literature that political scientists consider important and on which future scholars base their work. Our article breaks down the literature into a comprehensive list of topics and subtopics, which allows us to identify both an overall field canon and one for each topic, to assess whether some topics receive more attention than others, and to identify which topics are most clearly defined. We explore the extent to which diverse perspectives and methods are (or are not) taught to young scholars, and, although we identify sets of frequently assigned readings and authors within each topic, we also find considerable variation between seminars.  相似文献

About half of the nations that experience civil war eventually relapse into renewed conflict within a few years after the original war ends. This observation has motivated a stream of research into the factors that affect the risk of peace failure in the aftermath of civil war. While the outcome of the previous civil war—for example, military victory versus peace agreement—structures the post-war environment in ways that affect the risk of peace failure, the capacity of the post-war state to enact and implement policies that affect the incentives for and capacity of groups to undertake armed violence as a means of advancing their interests should also affect the risks of peace failure. Using Geddes’ categories of nondemocratic regime types, we will present a theory of how different regime types have varying capacities to repress and/or implement accommodative policies that affect the risk of peace failure. We test propositions derived from this theory with a series of event history models. Our findings suggest that while peace agreements significantly increase the duration of post-civil war peace, peace agreements involving some types of nondemocratic regimes actually increase the risk of post-civil war peace failure.  相似文献

This practical note demonstrates the role that haricot beans play in assisting women to become food and nutrition secure, to generate income, and to have sustainable livelihoods that are resilient to shocks. Based on qualitative research among female and male beneficiaries of a pulse innovation project implemented in southern Ethiopia, the note provides a summary of the critical voices of farmers, and the role that haricot beans play in empowering women. It also outlines some of the challenges that the project faced in achieving its empowerment objectives.  相似文献

Individuals are the single largest source of campaign contributions, yet we know little about their motivations. For instance, the existing literature questions whether individual contributors sophisticatedly differentiate among candidates according to policy positions, particularly among same‐party candidates. We analyze this issue by combining data from a new survey of over 2,800 in‐ and out‐of‐state donors associated with the 2012 Senate elections, FEC data on contributors’ professions, and legislative records. Three major findings emerge. First, policy agreement between a donor's positions and a senator's roll calls significantly influences the likelihood of giving, even for same‐party contributors. Second, there is a significant effect of committee membership corresponding to a donor's occupation; this holds even for donors who claim that other motivations dominate, but it does not appear to be motivated by an expectation of access. Third, conditional upon a donation occurring, its size is determined by factors outside a legislator's control.  相似文献

A hallmark finding in the study of public opinion is that many citizens approach the political realm with one‐sided attitudes that color their judgments, making attitude change difficult. This finding highlights the importance of citizens with weak prior attitudes, since they might represent a segment of the electorate that is more susceptible to influence. The judgment processes of citizens with weak attitudes, however, are poorly understood. Drawing from dual‐process models in psychology, I test the idea that citizens with weak explicit attitudes rely on implicit attitudes as they render political judgments. I find support for this conjecture in experimental and observational data. There are two main contributions. First, I show that an important and understudied segment of the electorate arrives at political decisions via automatic (but nonetheless predictable) mental processes. Second, I characterize the conditions under which implicit political attitudes matter more and less.  相似文献

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.  相似文献
