Most studies that explore parental knowledge of youths’ activities utilize parents’ and youths’ reports separately. Using
a sample of 938 rural early adolescents (53% female; 84% White), we explore congruence between mothers’ and youths’ perceptions
of maternal knowledge and its association with youth problem behaviors (delinquency, substance use, and attitudes towards
substances). Maternal overestimation of knowledge (compared to youths’ ratings) was positively associated with delinquency
and negatively associated with healthy drug attitudes. Significant differences in problem behaviors were found between four
groups created based on mothers’ and youths’ level of knowledge (High Youth and Mother, High Youth/Low Mother, Low Youth/High
Mother, and Low Youth and Mother). The High Youth and Mother group demonstrated less substance use and healthier drug attitudes
than the Low Youth and Mother group. The Low Youth/High Mother group had significantly higher levels of substance use and
delinquency than the High Youth and Mother group. Intervention implications are discussed. 相似文献

The current study investigated the effects of change blindness and crime severity on eyewitness identification accuracy. This research, involving 717 subjects, examined change blindness during a simulated criminal act and its effects on subjects' accuracy for identifying the perpetrator in a photospread. Subjects who viewed videos designed to induce change blindness were more likely to falsely identify the innocent actor relative to those who viewed control videos. Crime severity did not influence detection of change; however, it did have an effect on eyewitness accuracy. Subjects who viewed a more severe crime ($500 theft) made fewer errors in perpetrator identification than those who viewed a less severe crime ($5 theft). This research has theoretical implications for our understanding of change blindness and practical implications for the real‐world problem of faulty eyewitness testimony. 相似文献

This article contributes to the emerging literature on transparency by developing and empirically testing a theoretical framework that explains the determinants of local government Web site transparency. It aims to answer the following central question: What institutional factors determine the different dimensions of government transparency? The framework distinguishes three dimensions of transparency—decision making transparency, policy information transparency, and policy outcome transparency—and hypothesizes three explanations for each: organizational capacity, political influence, and group influence on government. Results indicate that each dimension of transparency is associated with different factors. Decision‐making transparency is associated with political influence; when left‐wing parties are strong in the local council, local government tends to be more transparent. Policy information transparency is associated with media attention and external group pressure, and policy outcome transparency is associated with both external group pressure and the organizational capacity. The authors discuss the implications for policy and administration. 相似文献

Innovation inducement prizes have been used for centuries. In the United States, a recent federal policy change—the America COMPETES Reauthorization Act of 2010—clarified and simplified a path by which all federal agencies can offer innovation inducement prizes, thus intensifying interest in how government agencies can most effectively design and apply such prizes. This paper aims to review and synthesize the academic literature on innovation inducement prizes, to clarify what has been learned that is relevant to current policy discussions, and to highlight unresolved questions that would be fruitful areas for future academic research and policy experimentation. Relative to the existing literature, this paper aims to bridge two gaps. First, I synthesize the academic literature in this area with an eye toward drawing lessons for the types of innovation inducement prizes under consideration by federal agencies under the America COMPETES Reauthorization Act. Second, I discuss the problem of how to evaluate the success or failure of innovation inducement prizes, arguing that careful empirical evaluations of innovation inducement prizes are needed in order to provide guidance to federal agencies (and others) on how to most effectively apply and design innovation inducement prizes. 相似文献

The Italian party system largely collapsed in the early 1990s, providing us with a natural experimental situation in which voters were confronted with new parties – indeed, with an entirely new party system. How did they react? This paper develops a number of expectations on the basis of existing theory and tests these expectations using a dataset consisting of election studies conducted in Italy between 1985 and 2008. We find that a new party system causes confusion as to where parties stand in left-right terms, making it difficult for voters to make their choices on the basis of ideological cues. The confusion is greatest among older voters – those already set in their habits of voting, but only the very oldest cohorts (containing voters over 60 years old) are significantly debilitated. 相似文献

STAR METRICS is a data platform that is being voluntarily and collaboratively developed by U.S. federal science agencies and research institutions to describe investments in science and their results. It initially emerged as a result of reporting requirements associated with the 2009 American Recovery and Reinvestment Act; it has developed in response to a recognized need to begin to systematically document federal investments in science and their immediate and long‐term results. The eventual goal is to draw information from existing data on scientific and economic activities as well as from research institutions' and federal science agencies' systems to provide data that can be used for a more scientific analysis of science investments and their outcomes. 相似文献

Carnivore scats recovered from animal attack and/or scavenging contexts frequently contain forensic evidence such as human bone fragments. Forensic cases with carnivore involvement are increasingly prevalent, necessitating a methodology for the recovery and analysis of scat evidence. This study proposes a method for the safe preparation of carnivore scat, recovery of bone inclusions, and quantification and comparison of scat variables. Fourteen scats (lion, jaguar, lynx, wolf, and coyote) were prepared with sodium-acetate-formalin fixative; analytical variables included carnivore individual, species, body size, and taxonomic family. Scat variables, particularly bone fragment inclusions, were found to vary among carnivore individuals, families, species, and sizes. The methods in this study facilitate safe scat processing, the complete recovery of digested evidence, and the preliminary identification of involved animals. This research demonstrates that scat collected from forensic contexts can yield valuable information concerning both the victim and the carnivore involved. 相似文献
