Taphonomic studies regularly employ animal analogues for human decomposition due to ethical restrictions relating to the use of human tissue. However, the validity of using animal analogues in soil decomposition studies is still questioned. This study compared the decomposition of skeletal muscle tissues (SMTs) from human (Homo sapiens), pork (Sus scrofa), beef (Bos taurus), and lamb (Ovis aries) interred in soil microcosms. Fixed interval samples were collected from the SMT for microbial activity and mass tissue loss determination; samples were also taken from the underlying soil for pH, electrical conductivity, and nutrient (potassium, phosphate, ammonium, and nitrate) analysis. The overall patterns of nutrient fluxes and chemical changes in nonhuman SMT and the underlying soil followed that of human SMT. Ovine tissue was the most similar to human tissue in many of the measured parameters. Although no single analogue was a precise predictor of human decomposition in soil, all models offered close approximations in decomposition dynamics. 相似文献

The purpose of this study was to conduct a longitudinal examination of predictors of sexual aggression among male juvenile offenders. Four hundred and four adolescent males between the ages of 14 and 17 years were recruited from juvenile probation offices to take part in a prospective study of substance use and sexual risk. At baseline, participants completed a series of questionnaires that assessed putative risk factors for sexual aggression. They then completed a measure of sexual aggression at the 6-month follow-up period. Correlational analyses revealed that participants who reported hard drug use, more frequent alcohol and marijuana use, and less severe offenses reported engaging in more severe sexual aggression. In addition, participants who reported higher impulsivity, sensation seeking, and externalizing behaviors also reported participating in more severe sexual aggression. When these variables were included in a regression analysis, only externalizing behaviors and severity of offense uniquely predicted severity of sexual aggression at the 6-month follow-up. 相似文献

Policy makers who embrace market‐based approaches to environmental regulation, typically eschew carbon taxes in favor of the political advantages of cap and trade, which offers lower visibility of costs to consumers and the opportunity to allocate valuable permits freely to industry. Against this backdrop, the article examines two surprising proposals for carbon taxes, by the government of British Columbia (BC) and by the federal Liberal Party of Canada. Both reflected a triumph of party leaders' normative “good policy” motives over “good politics.” The BC tax alone succeeded first because it was adopted by a party already in government. Second, the onset of a recession before the next elections shifted voters' attention to the economy, which advantaged the BC Liberals but disadvantaged their federal counterparts. However, proposals for carbon taxes were unpopular in both jurisdictions, offering a cautionary tale concerning the fate of politicians' normative commitments absent electoral backing. 相似文献

Animal-scavenging alterations on human remains can be mistaken as human criminal activity. A 32-day study, documenting animal scavenging on a human cadaver, was conducted at the Southeast Texas Applied Forensic Science facility, Sam Houston State University, Huntsville, Texas. A Stealth Cam Rogue IR was positioned near the cadaver to capture scavenging activity. An atypical scavenger, the bobcat, Lynx rufus, was recorded feeding on the cadaver. Scavenging by bobcats on human remains is not a predominant behavior and has minimal documentation. Scavenging behaviors and destruction of body tissues were analyzed. Results show that the bobcat did not feed on areas of the body that it does for other large animal carcasses. Results also show the bobcat feeds similarly during peak and nonpeak hours. Understanding the destruction of human tissue and covering of the body with leaf debris may aid forensic anthropologists and pathologists in differentiating between nefarious human activity and animal scavenging. 相似文献

This paper reviews 33 evaluations of Healthy Families America sites, with emphasis on 15 studies that include a control or comparison group. Outcome domains include child health and development, maternal life course, parenting, and child maltreatment. Parenting outcomes (e.g., parenting attitudes) show the most consistent positive impacts. Mixed results in other domains indicate the need for in-depth research to identify factors associated with better outcomes. Several factors that may contribute to differences in outcomes are discussed, including site implementation and quality, differences in family risk levels, and recent augmentations to program design. The paper also highlights two large-scale evaluations, one community-wide (Hampton, Virginia) and one statewide (Indiana), to illustrate exemplary evaluation approaches found in HFA research. Overall, HFA's continuing evolution has been positively impacted by researcher-practitioner partnerships. 相似文献

Many books have been written about the male spies of the early Cold War, but the women have not received nearly as much attention. In part, this is because journalists at the time reduced these women to gender stereotypes and portrayed them as neurotic old maids or svelte young seductresses. This article examines the cases of Elizabeth Bentley, Priscilla Hiss, Ethel Rosenberg, and Judith Coplon. It analyzes the gender constructions used in the media coverage of these women, and argues that exploring these constructions is crucial to understanding the significance of these cases. 相似文献
