‘Wilt’ occurs when a young person in high school expects to attend college but does not do so shortly after graduating. In this study we find that youth with no savings account in their own name are more likely to experience wilt than any other group examined. In multivariate analysis, young people who expect to graduate from a four-year college and have an account are approximately six times more likely to attend college than those with no account. Teens who expect to graduate from a four-year college and have designated a portion of their savings for college are approximately three times more likely to attend college than those with no account. Additionally, when savings are taken into account, academic achievement is no longer a significant predictor of college attendance. Policy implications are discussed. 相似文献

Academic economists perform an important function in advising politicians and state bureaucrats, lending them epistemological authority. This creates a challenge of institutional design and of professional vocation, of how these experts can combine their commitment to scientific analysis with their commitment towards their governmental patrons. This article examines the case of anti-trust economics, in which government economists are encouraged to remain as academically engaged as possible, so that their advice will be - or appear to be - unpolluted by political or bureaucratic pressures. Yet this ideal is constantly compromised by the fact that the economists are nevertheless government employees, working beneath lawyers. Max Weber's concept of a 'vocation' is adopted to explore this tension, and his two lectures, 'Science as a Vocation' and 'Politics as a Vocation' are read side by side, to consider this core dilemma of academic policy advisors. 相似文献

The current study examined the relationship between the victimization of youth, psychological distress and subsequent offending. It examined whether direct and vicarious victimization by exposure to violence in the family, among peers, and in the neighborhood, significantly predicted psychological distress among study participants and whether psychological distress significantly predicted subsequent offending over time. In addition, it examined the extent (if any) to which psychological distress mediated the relationship between victimization and subsequent offending. Method: study data are from wave 1 and wave 2 of the Buffalo Longitudinal Study of Young Men (BLSYM), a population based sample (n = 625) of young men, ages 16-19 years old in a metropolitan area of Buffalo, New York. A path analytic approach was used for the main analyses. Findings: personal, vicarious victimization by exposure to violence among peers, and perception of neighborhood safety were significant predictors of offending at wave 1. Personal and property victimization was significant predictors of psychological distress. Psychological distress did not have a significant relationship with offending at wave 1 yet, it did at wave 2. Vicarious victimization by exposure to violence among peers and offending at wave 1 were all significant predictors of offending at wave 2. The results highlight the need to respond to both direct and vicarious victimization among young males to reduce psychological distress and subsequent offending. 相似文献

Despite the importance of higher education, Hispanic immigrant youth still have far lower college attainment rate than whites in the U.S. Existing studies show the significant role of household assets on educational attainment even after controlling for income. Thus, this study examines the role of homeownership and school savings on Hispanic immigrant youth's college attendance and graduation. Findings show that homeownership is a significant positive predictor of Hispanic immigrant youth's college attendance and graduation, but parent school savings is not a significant predictor. Policy and practice implications discussed. 相似文献

The Deepwater Horizon drilling rig exploded on April 20, 2010 off the coast of Louisiana, and the ensuing oil spill caused substantial economic and environmental damage to states on the U.S. Gulf Coast. British Petroleum received strong public criticism for its role in the disaster and quickly attempted image repair strategies. These strategies centered on describing what they were doing to correct the problem and compensate the victims, but did not include strategies such as shifting the blame to the other companies involved nor admitting their own blame. This study applies Benoit's work in Image Repair to a content analysis of the press releases from British Petroleum in the initial aftermath of the Deepwater Horizon spill. We also note the difficulty of using this theory to capture the nuances of responses. 相似文献

Supply networks are becoming increasingly complex with multiple overlapping relationships between firms that may span across industries. Consequently, inventory management is becoming more difficult as managers have to cope with variability in the supply flows that originate from different parts of the network. Managers that quickly sense abnormal flows may intervene and adapt their inventory policies in response to system changes. In this article, we present a framework for sensing abnormal flows originating within the upstream supply network of a focal organization. Our framework combines time series modeling with process charts to identify abnormal flow patterns in the incoming supply streams. It is a flexible framework that uses off‐the‐shelf technology to provide managers with a process that can be employed for monitoring multiple individual or aggregated data streams originating within any complex system such as complex adaptive supply networks. We illustrate our framework on four years of longitudinal supply data from the second largest food bank in the United States. We identify multiple instances of abnormal supply flows and validate our results through rigorous inventory analysis as well as field‐based expert interviews. We discuss the implications of our findings for inventory management in complex supply networks, both from academic and practitioner points of view. 相似文献

This research investigates how information asymmetry between the firm and its investors can influence supply chain disruptions. In such settings, these actors may be induced to take steps which exacerbate rather than ameliorate both the likelihood and impact of disruptions. By better understanding these mechanisms, managers and investors alike are better armed to avoid the costly consequences. 相似文献
