Abstract: With sexual assault evidence, the visualization of spermatozoa confirms that ejaculation has occurred. However, microscopic examination of spermatozoa is a laborious process and can sometimes result in sperm cells being overlooked. Here, we present the developmental validation of the SPERM HY‐LITER? kit, which contains a human sperm–specific mouse monoclonal antibody coupled to a fluorescent Alexa 488 dye. The kit was tested using samples of human semen, saliva, blood, and urine, various animal semen extracts, sexual lubricants, and a commercially available spermicidal film. Postcoital vaginal swabs, degraded semen samples, and samples prepared with sample fixation techniques that deviated from the kit‐provided protocol were also tested. In each case, the SPERM HY‐LITER? kit was demonstrated to bind only to human sperm cell heads. Limitations to this fluorescent staining procedure include nonspecific staining and increased background fluorescence with extreme heat fixation in some samples. 相似文献

In this article, we describe a quasi‐experiment in which experienced incarcerated burglars (n = 56), other offenders (n = 50), and nonoffenders (n = 55) undertook a mock burglary within a virtual neighborhood. We draw from the cognitive psychology literature on expertise and apply it to offending behavior, demonstrating synergy with rational choice perspectives, yet extending them in several respects. Our principal goal was to carry out the first robust test of expertise in offenders by having these groups undertake a burglary in a fully fledged reenactment of a crime in a virtual environment. Our findings indicate that the virtual environment successfully reinstated the context of the crime showing clear differences in the decision making of burglars compared with other groups in ways commensurate with expertise in other behavioral domains. Specifically, burglars scoped the neighborhood more thoroughly, spent more time in the high‐value areas of the crime scene while traveling less distance there, and targeted different goods from the comparison groups. The level of detail in the data generated sheds new light on the cognitive processes and actions of burglars and how they “learn on the job.” Implications for criminal decision‐making perspectives and psychological theories of expertise are discussed. 相似文献

The American alligator inhabits bodies of fresh water in Florida and other southeastern states. Although attacks on pets are frequent, alligator attacks on humans are relatively rare because of the animal's natural fear of man. Because of the rarity of attacks on humans, the pathologic findings and pathophysiology of death in such cases have not been well characterized in the literature. We report three cases of fatal alligator attacks that occurred in southwest Florida, each with different pathologic findings and mechanisms of death. Although the cause of death in each case was attributed to the alligator attack, the mechanisms of death differed and included exsanguination because of amputation of an extremity, overwhelming sepsis, and drowning. These cases illustrate the varied pathophysiologies associated with deaths due to alligator attacks on humans and the features that distinguish alligator bites from those of other aquatic predators. 相似文献

Public choice scholars state that federal systems are more responsiveand efficient than unified ones. In addition, through overlappingunits, federal systems provide a measure of interjurisdiclionalequity. This research addresses the equity claim and extendsthe testing of it beyond previously-examined federal, state,and county role! to the unexamined role of metropolitan districtsthat overlap cities and suburbs. Services provided by the MetropolitanMilwaukee Sewerage Qistricl and the Milwaukee Area TechnicalCollege are found to be disparity-reducing between the Cityof Milwaukee and its suburbs. 相似文献

Although significant progress has been made in developing leadership theory and understanding the traits, skills, behaviors, and styles that make a good leader, progress in bridging the gap between theory and practice using models of leadership training and development has been slow. This research attempts to answer the question of whether leadership training and development programs in the public sector improve leader and organizational performance. The findings indicate that a combination of coaching, classroom instruction, feedback, and experiential training has a significant impact on leader performance. In addition, organizational effectiveness improves for organizations whose leaders received the intervention. This article enhances our understanding of the impact that training and development can have on leader and organizational outcomes. 相似文献

Public-private partnerships are the preferred vehicles for the planning, financing and implementation of contemporary urban development. Scholarship on public-private partnerships tends to examine their activities in advancing development. Less attention is accorded to their internal dynamics or governance. While partnerships are intended to build internal consensus and obtain consent in order to carry out urban development, this premise assumes that coordinated public and private interests are in play. This paper examines the internal governance of two public-private partnerships in Rochester, New along three dimensions: conformity to a collective purpose or vision, leadership structure and organizational style. 相似文献
