The current experiment examined whether adjusting-amount and adjusting-delay procedures provide equivalent measures of discounting. Pigeons' discounting on the two procedures was compared using a within-subject yoking technique in which the indifference point (number of pellets or time until reinforcement) obtained with one procedure determined the value of the corresponding variable in the yoked condition with the other procedure. Behavior on each procedure was well described by a hyperbolic discounting function. Results revealed no systematic differences in the degree of discounting as measured by the discounting rate parameter of the hyperbola in Experiment 1, which used 20-mg pellets. These results were replicated in Experiment 2 using smaller, 14-mg pellets, which potentially yield more precise measurement of indifference points on the adjusting-amount procedure. The finding that estimates of the k parameter in the hyperbolic discounting function obtained with one procedure did not differ systematically from estimates obtained from the same subjects with the other procedure represents strong support for the hypothesis that the same process underlies the discounting of delayed rewards on both adjusting-amount and adjusting-delay procedures.  相似文献

The question of how crime impacts on others has generated a wealth of research over the past few decades. However, there is surprisingly little knowledge about how ‘high‐profile’ crimes impact on community members who live in a town that has become synonymous with the crime itself. This study involves interviews with community members who lived or worked in the town of Gloucester when the serial killings perpetrated by Fred and Rosemary West were discovered in 1994. An interpretative phenomenological analysis explores the lived experiences and meaning‐making processes engaged in by the participants. Findings highlight their attempts to make sense of a high‐profile case that stigmatised their own community and the practices of identity management that continue to operate some 20 years later.

Researchers have begun to explore the problem of mass data breaches, where consumer information is acquired by cybercriminals and sold in open markets on-line. Although studies document the social processes of the market and relationships between buyers and sellers, few have considered the revenues earned from market transactions. This study explored these issues using a sample of threads from 10 Russian language and 3 English language Web forums used to sell stolen data. Estimates were generated on the total number of transactions completed by participants along with the advertised prices for the two most common forms of personal information sold. The findings demonstrated that buyers may earn a range of revenues from the sale of stolen data, although this figure was smaller than the potential profits earned from fraudulent use and identity crimes by data buyers. The implications of this study for cybercrime research and policy are explored in detail.  相似文献

This qualitative ethnographic study sought to gain insight into how participants in the Bondage/Discipline/Sadomasochism (BDSM) community negotiate and maintain boundaries in order to engage in mutually satisfying BDSM activities. Additionally, this study explored how boundary violations are handled by a community stigmatized by the larger culture. Results indicated that participants employ methods to keep BDSM play ‘safe, sane, and consensual’, although boundary violations do occur. These violations are handled internally by appointed community members and participants may engage in retaliatory behavior, with the occasional member employing violence. Implications of the research and future avenues for exploration are discussed.  相似文献

In this study, two telephone interviews that assessed both religious involvement and health‐related quality of life were conducted approximately 2.5 years apart in a national sample of 290 African Americans. Religious involvement was assessed with an instrument that measured both personal religious beliefs (e.g., having a personal relationship with God) and more public religious behaviors (e.g., attending church services). Health‐related quality of life was measured with version 2 of the Medical Outcomes Study 12‐item short form (SF‐12v2). Structural equation models indicated that higher religious beliefs at baseline predicted better physical and mental health 2.5 years later. Higher religious behaviors at baseline contributed smaller, complementary suppression effects. Physical and mental health indicators from the SF‐12v2 at baseline did not predict changes in either religious beliefs or religious behaviors over time. These findings indicate that, for African Americans, personal religious beliefs lead to beneficial health effects over time, whereas individual differences in health do not appear to predict changes in religious involvement.  相似文献

Abstract Cybercrime has created substantial challenges for law enforcement, particularly at the local level. Most scholars and police administrators believe that patrol officers need to become more effective first responders to cybercrime calls. The evidence illustrates, however, that many patrol officers are neither adequately prepared nor strongly interested in taking an active role in addressing cybercrime at the local level. This study, therefore, examined the factors that predicted patrol officer interest in cybercrime training and investigations in two southeastern U.S. cities. The study specifically examined the relationship between demographics, cybercrime exposure, computer training, computer proficiency, Internet and cybercrime perceptions, and views on policing cybercrime with officer interest in cybercrime investigation training and conducting cybercrime investigations in the future. Officer views on policing cybercrime, particularly whether they valued cybercrime investigations and believed that cybercrime would dramatically change policing, along with their computer skills, were the strongest predictors of interest in cybercrime efforts. Officers who had received previous computer training were less interested in additional training and conducting investigations. These findings support the argument that more command and departmental meetings focusing on the value of investigating these types of crime need to be held in order to increase officer interest.  相似文献

Despite much research on how interests are related to personality and creativity, comparatively little work has focused on how different college majors as categorized by the RIASEC model compare on these constructs. In this study, 3295 college students (207 Realistic, 1945 Investigative, 447 Artistic, 480 Social, and 216 Enterprising) completed a five-factor personality measure, a brief self-report of creativity, and the Compound Remote Associates Task (CRAT). Investigative and Artistic majors scored higher on openness and self-assessed creativity than Realistic and Social majors, and Investigative majors were much more agreeable than other majors.  相似文献
