Contrary to the general belief, systemic risk does not only regard the risk posed by balance sheet relationships and interdependencies among institutions. It also features a temporal dimension related to the inappropriate responses of financial market participants to changes in risk over time. This paper proposes a method to simultaneously address the cross-sectional and the time dimension in which systemic risk materializes. The method is based on the TOPHITS algorithm. It provides three scores, namely borrowing, lending and time scores: the first two represent the systemic importance of the borrowing and the lending activity associated with each financial institution,while the third represents an empirical Early Warning Signal of the financial crisis. Our findings reveal that the identification of the time score as an indicator for an incoming market distress could be relevant to design macro prudential policies. 相似文献

Determining priority importance is a matter of concerns among the organization to improve their performance. One of the important
aspects that should be considered by the organization is management of human resources, comprising of members who have their
own family life. In this paper, we deliver a new perspective for organization to provide priority importance for their members
with respect to family matters in order to inculcate the sense of belonging in the organization. To be effective in considering
family matters in the organizational policy making, closer look of family characteristics are required. The idea of translating
several family characteristics as quality variables and applying the quality function deployment (QFD) method to these variables
could present a new way of improving the decision making in the organization by considering the process of decision in the
family. Quality function deployment for family (QFDF) produces a friendly interpretation of a highly complex and intangible
matters around family life; thus, making the assessment of a family easier. QFD is applied on the data gathered from a questionnaire
survey based on 1,213 families in West Malaysia, Malaysia. Twelve variables are identified as voice of family, where seven
of them are found to have the highest priority of importance. These variables could also be translated into quality variables
in the context of organization, the strategy of improvement for the family could be interpreted as strategy for improvement
in the organization. Furthermore, the results of this study provide suggestion to improve actions for managing human resource.
In the discussion, three most high ranked variables from both perspectives of family and organization are considered. 相似文献

Criminologists have long reported the existence of racial disparity in the criminal justice system, but the important question
is why. While some argue that observed differences are a consequence of more criminal behavior among minorities, the weight
of the evidence indicates that this is but a partial explanation. In this paper, we study data from a sample of juveniles
to examine how racial differences in early police contact, and important social environments—family, school, and neighborhoods—affect
later contact and arrests, controlling for self-reported delinquency. We find that early (in middle school) contact with police
is an important predictor of later (high school) arrests. Also we found that, in addition to being male and living in a low-income
family, children who have parents who have a history of arrest, who have experienced school disciplinary actions, who have
delinquent peers, and who are in networks with deviant adults are more likely to have problems with law enforcement. These
factors help to explain racial differences in police contacts and arrests. 相似文献

Prolonged emergency department (ED) visits are associated with a number of adverse outcomes for patients as well as lower patient satisfaction scores and increased costs. Several factors that influence the length of ED visits are out of the control of hospital employees, but some opportunities exist to improve performance. For this study, the ED department of a 150-bed hospital in the southeastern United States wanted to improve door-to-discharge time. To do so, a subprocess of door-to-discharge time was targeted, door-to-order. After analyzing the process, the team created standard orders for the 10 most common presenting conditions in the ER with preapproval, allowing nurses to submit the orders without the provider first visiting the patient. Following the process change, daily feedback was added to increase utilization of the preapproved orders. Reductions in door-to-order times and door-to-discharge were observed and patient satisfaction remained stable. Implications for future research in this area are discussed. 相似文献

The most universally experienced sexual response is sexual desire. Though research on this topic has increased in recent years, low and high desire are still problematized in clinical settings and the broader culture. However, despite knowledge that sexual desire ebbs and flows both within and between individuals, and that problems with sexual desire are strongly linked to problems with relationships, there is a critical gap in understanding the factors that contribute to maintaining sexual desire in the context of relationships. This article offers a systematic review of the literature to provide researchers, educators, clinicians, and the broader public with an overview and a conceptual model of nonclinical sexual desire in long-term relationships. First, we systematically identified peer-reviewed, English-language articles that focused on the maintenance of sexual desire in the context of nonclinical romantic relationships. Second, we reviewed a total of 64 articles that met inclusion criteria and synthesized them into factors using a socioecological framework categorized as individual, interpersonal, and societal in nature. These findings are used to build a conceptual model of maintaining sexual desire in long-term relationships. Finally, we discuss the limitations of the existing research and suggest clear directions for future research. 相似文献

Schools at the P-12 level increasingly face crises related to school shootings, violence, and other tragedies. Understanding the communication challenges schools face is paramount to assisting schools with communication before, during, and after crisis events. The current study focuses on the challenges created by media interest in such crises and the strategies implemented to overcome these challenges and provide responsible information to stakeholders. Interviews conducted with 21 school crisis teams at the P-12 level revealed that sensationalism, seeking alternative routes to information, and framing were key challenges in working with the media. In light of these challenges, administrators focused on creating media plans, building relationships with the media, being accurate but guarded, and communicating reassurance and reunification. Implications are discussed for school districts nationally. 相似文献

For nearly four decades, child welfare policy and practice have focused on the achievement of legal permanence for children in foster care. Although federal child welfare policy has resulted in the movement of children from state custody to legally permanent adoptive or guardianship families, little is known about the quality and enduring nature of these placements. A significant challenge of the twenty-first century child welfare system is how to ensure the well-being of children currently living with adoptive parents or guardians. This paper discusses child welfare policy and trends related to post-permanency well-being, including the decrease in Title IV-E foster care caseloads nationwide and the simultaneous increase in Title IV-E adoptive and guardianship caseloads. We highlight the needs of a twenty-first century child welfare system, including increased federal efforts to ensure child permanence and well-being after legal adoption or guardianship has been achieved, as well as more rigorous longitudinal and interdisciplinary research focused on the post-permanency adjustment of children and their families. 相似文献

Undergraduate career planning courses have shown efficacy in decreasing students’ negative career thoughts; however, universities have minimally applied these courses to science, technology, engineering, and math (STEM) populations. This study compared the influence of a STEM‐focused career planning course for undecided STEM students with a seminar course for decided STEM majors. An analysis of covariance with covariate adjustment revealed that undecided career planning students had lower adjusted mean scores on a measure of negative career thinking than the decided STEM majors after the first semester of college. The results provide support for the efficacy of STEM‐focused career planning courses and measuring negative career thoughts with STEM undergraduates. 相似文献

Over the past few years a number of studies have focused on the disadvantages confronted by students who are the first in their families to attend university. Their liabilities include relatively low levels of preparedness, a lack of involvement in campus activities, and low levels of academic achievement. Rather than accepting the universality of this characterization, in this article, these negative characteristics and experiences were viewed as one ‘ideal type.’ Using this ideal type as a reference point, the current study focused on a period in Canadian history in which first generation students were the norm. In an examination of Glendon College, York University, located in Toronto Canada, in the mid 1960s, it was found that the experiences of the first generation did not fit the ideal type. Those who likely were the first in their families to attend university were prepared for their studies, involved in campus activities, and earned good grades. Possible explanations for this deviation from the ideal type include the buoyancy of the economy in the mid-sixties, an expanding university sector, the size and relative intimacy of the College, the way in which high schools prepared students for university, and stringent admission requirements. 相似文献
