The full range of the meaning of revenue emerges from seriously considering how people understand revenues from various perspectives. Explicit discussion of revenue meanings may contribute to improving our understanding of revenue-related phenomena. Insights can be gained from considering revenues from various perspectives. Revenue conceptualizations examined here range from the most immediate one, the notion of resources, to policy devices, mediation of relationships, measurements of political situations, and values. These discussions show that a variety of meanings are associate with revenues and that revenues are at least as fundamental to public budgeting as expenditures. 相似文献

This paper looks at the mechanisms through which financial corruption thrives both in Canadian society and elsewhere. There is a significant literature that examines the embeddedness of capitalism and the biases and advantages that this provides to all profit-directed activities. My focus is more on the social and attitudinal ways in which the embeddedness is exploited and simultaneously denied while serving as a lifestyle of the financially advantaged. I am interested in these cultures that develop and how the people within them come to accept their impunity and their entitlements as normal or at least ‘business as usual’. In addition, I am interested in the resistance to change pertaining to corruption of the powerful segments of our society. I present case studies that expose not only the privileges and advantages that capital allocates to the wealthiest but also a picture of the national and international social interactions among the clients, the enablers, and the regulators whereby the access to privilege is legitimized. 相似文献

We identify situations in which conditioning on text can address confounding in observational studies. We argue that a matching approach is particularly well-suited to this task, but existing matching methods are ill-equipped to handle high-dimensional text data. Our proposed solution is to estimate a low-dimensional summary of the text and condition on this summary via matching. We propose a method of text matching, topical inverse regression matching, that allows the analyst to match both on the topical content of confounding documents and the probability that each of these documents is treated. We validate our approach and illustrate the importance of conditioning on text to address confounding with two applications: the effect of perceptions of author gender on citation counts in the international relations literature and the effects of censorship on Chinese social media users. 相似文献

This study examined the structural social support of 132 men residing in a network of self-run, substance abuse recovery homes. The impact of different types of social relationships on individuals' substance use patterns and recovery attempts was investigated. Results suggest that varying relationship types (i.e., parents, significant other, friends, children, coworkers) have significantly different influences on use and recovery. Additionally, each type of relationship had differential impacts on use versus recovery. Children were the sole relationship type that affected both substance use and recovery attempts in a positive nature, suggesting that children may have a beneficial impact on reducing. 相似文献

The Oxford House model for substance abuse recovery has potential economic advantages associated with the low cost of opening up and maintaining the settings. In the present study, annual program costs per person were estimated for Oxford House based on federal loan information and data collected from Oxford House Inc. In addition, annual treatment and incarceration costs were approximated based on participant data prior to Oxford House residence in conjunction with normative costs for these settings. Societal costs associated with the Oxford House program were relatively low, whereas estimated costs associated with inpatient and incarceration history were high. The implications of these findings are discussed. 相似文献

Under the Americans with Disabilities Act (ADA), employers must provide employees with disabilities reasonable accommodations that will enable them to perform job duties, as long as the accommodations do not financially burden the organization. Two studies were conducted to investigate whether disability origin and/or prior work history impermissibly influence the granting of reasonable accommodations under the ADA. In both studies, participants granted more accommodations for employees whose disability was caused by some external factor than for those whose disability was caused by the employee's own behavior. In Study Two, participants also granted more and costlier accommodations for an employee with an excellent work history than for an employee with an average work history. Implications of the use of extralegal factors in accommodation decisions are discussed. 相似文献

For optimal DNA short tandem repeat (STR) typing results, the DNA concentration ([DNA]) of the sample must be accurately determined prior to the polymerase chain reaction (PCR) amplification step in the typing process. In early 2004, the National Institute of Standards and Technology (NIST) conducted an interlaboratory study to help assess the accuracy of DNA quantitation in forensic DNA laboratories. This study was designed with four primary purposes: (1) to examine concentration effects and to probe performance at the lower DNA concentration levels that are frequently seen in forensic casework; (2) to examine consistency with various methodologies across multiple laboratories; (3) to examine single versus multiple source samples; and (4) to study DNA stability over time and through shipping in two types of storage tubes. Eight DNA samples of [DNA] from 0.05 ng/microL to 1.5 ng/microL were distributed. A total of 287 independent data sets were returned from 80 participants. Results were reported for 19 different DNA quantitation methodologies. Approximately 65% of the data were obtained using traditional slot blot hybridization methods; 21% were obtained using newly available quantitative real-time PCR (Q-PCR) techniques. Information from this interlaboratory study is guiding development of a future NIST Standard Reference Material for Human DNA Quantitation, SRM 2372. 相似文献
