Amidst calls for more scrutiny of the failure of infrastructure public–private partnerships (PPPs), uncertainty about how we can measure failure remains, and little systematic evidence illuminates its likelihood. Our mixed‐methods design explores the notion of failure and identifies the conditions under which it happens. The first phase of our research employs documentary analysis and semistructured expert interviews, and identifies project cancellation as capturing the most severe occurrences of failure. A second phase statistically analyzes a unique World Bank data set capturing the provisions of over 4,000 infrastructure PPPs launched between 1990 and 2015 in 89 countries. We find robust evidence supporting the theoretical claim that PPPs are less likely to be canceled in countries with more veto points among their political institutions to restrain politicians from intervening in policy implementation. Cancellation is a rare, but valid indicator of failure, and the importance of veto players clarifies how political risk operates in this context. 相似文献

While having a purpose in life has been theorized as a developmental asset, the extent to which adolescents cultivate a meaningful
sense of direction is not well understood. In the present study, cluster analysis was used to classify adolescents by levels
of purpose exploration and commitment. The sample (N = 318; 55% female) consisted of youth aged 14–18 and was predominantly White/non-Hispanic (76.3%). Results supported four
meaningful yet distinguishable profiles of youth purpose that are largely consistent with theories on identity formation:
Achieved, Foreclosed, Uncommitted, and Diffused. Hypothesized linkages with affect and hope were established across the profiles
such that positive emotions and goal-directed thinking were most apparent among Achieved and Foreclosed youth and least apparent
among Diffused and Uncommitted youth. Overall, findings demonstrate the inherent complexity in adolescents’ engagement with
purpose and suggest a correspondence between stronger commitments to purpose and youths’ sense of personal agency and well-being. 相似文献

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9?% female, 46.9?% male; racial distribution 79.5?% Caucasian, 11.9?% Hispanic/Latino, and 3.6?% Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents' help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14?%) students reporting SI, only 23?% told an adult, 29?% sought adult help, and 15?% did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students' increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students' perceptions of the availability and capability of adults to help them, and strengthening students' understanding of how existing resources can help them cope. 相似文献

There is a growing body of research that suggests parallels between assimilation and increased adolescent violence, which is often referred to as the “immigrant paradox” in the United States. Few studies explore how theories, such as routine activity and lifestyle, could explain the relationship between assimilation and increased violence. This study explores whether and how the adolescent associations between routines, lifestyles, and adolescent school-based victimization vary across immigration generations. Data are drawn from the Educational Longitudinal Study of 2002, which is a nationally representative sample of tenth graders. This study focuses on a subsample consisting of 9,870 first (N = 1,170, 12 %), second (N = 1,540, 16 %), and third-plus (N = 1,117, 73 %) generation public school students (N = 5,050; 51 % female) in 580 public schools for this analysis of routine activity, lifestyle, and school-based victimization across immigration generations. Findings do indicate important nuances related to immigration in the conceptual links between routine activity, lifestyle, and adolescent victimization. For instance, engagement in school-based sport activities is a potential risk factor for first and second generation adolescents but is found to be a potential insulating factor against violent victimization for third-plus generation adolescents. The implications of the relationships between routines, lifestyles, and violence across immigration generations are discussed more generally. 相似文献

Cloud technology offers wonderful potential for users in terms of convenience, ease of obtaining updates etc. However, it presents significant legal challenges. Our laws, largely based on notions of territoriality, struggle to respond to technology in which lines on maps are largely irrelevant. In this article, I articulate some of the specific challenges. The law of contract, tort and national regulation might all apply to a claim of breach of privacy in relation to material uploaded to the cloud. Unfortunately, each of the jurisdictions studied would approach the issues in different ways, potentially creating significant confusion. The article proposes a need for international co-operation and agreement on these matters. 相似文献

Governments are increasingly using public‐private partnerships (P3s) to draw the private sector into more active participation in infrastructure development. Climate action initiatives have not typically yielded profitable results for the private sector, and might therefore constrain the placing of conditions by governments on P3 arrangements. This article investigates a major P3 infrastructure project in British Columbia – the Canada Line extension to Vancouver's urban rail transit network – and concludes that the P3 organization did not constrain the government's capacity to pursue policy objectives for climate action. This counterintuitive result occurred because public sector leadership enabled an effective engagement with environmental policy priorities. 相似文献

The article argues that Islamist terror is driven by irrational forces; it analyzes jihadist values and doctrines that animate Islamic revolutionaries; it then contends that jihadist movements go through a cycle of mobilization, extremism, implosion and recreation. Finally, it assesses the prospects for jihadist revitalization, extremism, and decline in Syria and the Sahel. Examples from the Iraqi and Algerian jihadist campaigns are used for illustrative purposes throughout. 相似文献

This part develops the author's previous effort to produce a Marxist theorisation of the role of legal discourse in democratic capitalist societies that properly acknowledges its ‘relative autonomy’. The paper proceeds by way of a critique of earlier efforts to theorise the non-economic dimensions of productions. It ends with an attempt to theorise the discursive dimension of production so that the effects of the law in the production process may be investigated in a way that overcomes the ‘incommensurability problem’ that otherwise seems to vitiate efforts to provide analyses that work at both the macro and micro levels. 相似文献

The issue is not whether a successful transition in Afghanistan is possible,it is rather whether some form of meaningful transition is probable-a very different thing.The answer is a modest form of strategic success is still possible,but that it is too soon to know whether it is probable.The Afghan government,the U.S.and its allies,and aid donors have not made enough collective progress to assign a clear level of probability.Equally important,it is too soon to know what level of forces they will maintain in Afghanistan through the end of 2014 and beyond,what levels of military and civil aid they will provide,and what level of success Afghanistan can achieve moving forward. 相似文献
