Many comparisons of federal and private sector pay have found large federal pay premiums. Those studies have focused on individuals with similar pay-related characteristics, such as education and experience. Comparisons conducted by the federal government for purposes of determining the pay raises of federal white collar employees, however, find large federal pay disadvantages. Those comparisons focus on similar jobs. This article offers one possible explanation for the differences in results. 相似文献

Literature suggests that developing empathy for animals will result in caring toward other living things. Empathy is often seen as a key building block of prosocial behavior and can be defined as sharing of another person’s emotions and feelings. In older childhood and adolescence, a lack of empathy may have deleterious consequences, leading to antisocial behaviors. However, children and adolescents who exhibit human and non-human animal aggression have often been witness to animal cruelty in the home. When empathy and prosocial behaviors are not learned in the home, there are alternatives to facilitate that process. This study discusses the development of empathy and prosocial behavior by working with animals through the modalities of humane education, restorative justice, and animal-assisted programs. Each modality focuses on building compassion, caring, responsibility, and kindness with the help of animals. Through these violence prevention programs, children and adolescents can develop empathy, which will decrease the likelihood of future aggression. 相似文献

Business incubators have become a popular policy option and economic development intervention tool. However, recent research shows that incubated firms may not benefit significantly from their incubator relationships, and may even be more vulnerable to failure post departure (graduation) from an incubator. These findings suggest that the impact of business incubation on new venture viability may be contingent on the type of support offered by an incubator and attributes of business environments within which incubation services are provided. Incubation services that protect and isolate ventures from key resource dependencies may hinder venture development and increase subsequent vulnerability to environmental demands. Alternatively, incubation services that help ventures connect and align with key resource dependencies are likely to promote firm survival. We propose that incubators vary in the services and resources they offer, and that university incubators typically provide greater connectivity and legitimacy with respect to important contingencies associated with key industry and community stakeholders. This leads us to propose that university affiliation is an important contingency that affects the relationship between firms’ participation in incubators and their subsequent performance. The purpose of this study is to evaluate this contingency by examining whether firms graduating from university incubators attain higher levels of post-incubation performance than firms participating in non-university affiliated incubators. We test this by evaluating the performance of a sample of graduated firms associated with the population of university-based incubators in the US contrasted against the performance of a matched cohort of non-incubated firms. The analysis uses an enhanced dataset that tracks the number of employees, sales, and the entry and graduation (departure) points of incubated firms from a university incubation program, so as to delineate the scope of influence of the incubator. 相似文献

This ballistics study examines whether saline breast implants can decrease tissue penetration in firearm injuries. We hypothesize that the fluid column within a saline breast implant can alter bullet velocity and/or bullet pattern of mushrooming. The two experimental groups included saline implants with 7.4 cm projection and a no implant group. The experimental design allowed the bullet to pass‐through an implant and into ballistics gel (n = 10) or into ballistics gel without passage through an implant (n = 11). Shots that passed through an implant had 20.6% decreased penetration distance when compared to shots that did not pass‐through an implant; this difference was statistically significant (31.9 cm vs. 40.2 cm, p < 0.001). Implant group bullets mushroomed prior to gel entry, but the no implant group mushroomed within the gel. Bullet passage through a saline breast implant results in direct bullet velocity reduction and earlier bullet mushrooming; this causes significantly decreased ballistics gel penetration. 相似文献
