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
Volatile organic compounds (VOCs) are by-products of cadaveric decomposition and are responsible for the odor associated with decomposing remains. The direct link between VOC production and individual postmortem microbes has not been well characterized experimentally. The purpose of this study was to profile VOCs released from three postmortem bacterial isolates (Bacillus subtilis, Ignatzschineria indica, I. ureiclastica) using solid-phase microextraction arrow (SPME Arrow) and gas chromatography–mass spectrometry (GC-MS). Species were inoculated in headspace vials on Standard Nutrient Agar and monitored over 5 days at 24°C. Each species exhibited a different VOC profile that included common decomposition VOCs. VOCs exhibited upward or downward temporal trends over time. Ignatzschineria indica produced a large amount of dimethyldisulfide. Other compounds of interest included alcohols, aldehydes, aromatics, and ketones. This provides foundational data to link decomposition odor with specific postmortem microbes to improve understanding of underlying mechanisms for decomposition VOC production. 相似文献
This article uses a new dataset of coded Alberta Throne Speeches from 1906 to 2017 to identify patterns of provincial policy attention to place and urban place across policy issues and time. We discuss three main findings. First, provincial attention to place and urban place is influenced by policy domain: place‐based attention is generally absent in some policy domains, such as macroeconomic policy, and prevalent in others, such as health care. Second, place‐based attention is patterned over time, with a noticeable peak in the post‐war “province‐building” years and distinct troughs in other periods. Finally, we discuss the related but distinct patterns of attention to place and urban place across policy domains and time. 相似文献
Research on the health benefits and consequences of close relationships has suggested the linkage in daily emotions (i.e., coregulation) between close partners is an important relationship dynamic. While the coupling of daily emotions among family members (parent–child and marital dyads) has been widely documented, research examining emotional coregulation among ethnic minority youth during adolescence, a period marked by heightened emotion and risk for psychopathology, remains an important area in need of exploration. This study examined correlates of emotional coregulation in a sample of Mexican-origin adolescents (Mage?=?15.02, SD?=?.83) and their parents (Mage?=?41.93, SD?=?6.70). Dyads reported on daily levels of distress and happiness for 14 consecutive days across two waves of data collection a year apart (nwave1?=?428 dyads, nwave2?=?336 dyads). Dyads who reported getting along were more likely to coregulate their daily happiness. Importantly, coregulation of distress was only present in older adolescents who reported above average levels of internalizing symptoms. The results suggest coregulation of distress may shape or be shaped by poor mental health during the later years of adolescence, a time when youth may be establishing a degree of emotional autonomy from parents.
This paper explores the influence of central party politics in Auckland local government, in New Zealand’s largest city, following the 2010 amalgamation. Political parties have been an accepted and dominant presence in European representative democratic local government, throughout the 20th century. Not so, however, in New Zealand and Australia, where citizens have ‘flocked to the banner “Keep Politics out of Local Government”. Our analysis of the self-declared party accreditation status of candidates and elected members demonstrates that political affiliation, at least in the main centre Auckland, is on the rise, counter to assumptions that New Zealand local government is largely removed from central politics. 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
Research on the mechanisms by which interparental conflict (IPC) affects child depression suggests that both parenting and
children’s conflict appraisals play important roles, but few studies have explored the role of general cognitive style or
included both parenting and cognitions in the same design. Moreover, the effects of IPC on minority children are not well
understood. In this longitudinal study, parenting was examined as a mediator of the relation between increasing IPC and change
in depression. General cognitive style was included as a moderator. The combined influence of parenting and cognitions was
also explored. A racially and ethnically diverse sample of 88 fifth and sixth graders from two urban schools reported their
cognitive style, depressive symptoms, and perceptions of conflict and parenting at two time points separated by one year.
Parental warmth/rejection mediated the relation between IPC and depression, and general cognitive style acted as a moderator.
Parenting, cognitive style, and IPC did not significantly interact to predict change in depression over time. Findings indicate
that both parenting and children’s general cognitive style play a role in understanding the impact of increasing IPC on children’s
well-being. 相似文献
Organizational culture is widely considered to be one of the most significant factors in reforming and modernizing public administration and service delivery. This article documents the findings of a literature review of existing qualitative and quantitative instruments for the exploration of organizational culture. Seventy instruments are identified, of which 48 could be submitted to psychometric assessment. The majority of these are at a preliminary stage of development. The study's conclusion is that there is no ideal instrument for cultural exploration. The degree to which any measure is seen as "fit for purpose" depends on the particular reason for which it is to be used and the context within which it is to be applied. 相似文献
