All part of the process? A qualitative examination of change in online child pornography behaviors

Over the past two decades, there has been increased attention on offending behaviors and motivations of child pornography offenders (CPOs). Although existing research has provided a knowledgeable foundation in regard to this offending subpopulation, the literature has been relatively limited on examining changes in offender behaviors and motivations. This study used interviews with 25 online CPOs in a southern state to identify themes underlying offending behaviors and motives at onset, as well as, continuation of offending over time. We found that offenders reported various circumstances (ranging from intentional to unintentional) and motivations (including thrill-seeking and attraction) at onset; however, CPOs reported thrill-seeking and attraction to be the most common factors driving their continued offending. We applied these themes to the existing literature on child pornography offending and recommended directions for future research. Based on our findings, we offered considerations for the treatment of CPOs.     

Culture and Negotiation Strategy

In this article the authors investigate the relationship between culture and joint gains by examining the role of information sharing and power strategies in intracultural negotiations. Previously, the authors found that the relationship between cultural values or norms and joint gains was uncertain in six cultures: France, Russia, Japan, Hong Kong, Brazil, and the United States. Of the five values and norms measured, only norms for information sharing in negotiation were directly related to joint gains. This article explores and extends prior findings by investigating the strategies used by negotiators in the same six cultures. Cultures that maximized joint gains used direct information-sharing strategies or a combination of indirect and direct strategies. Power strategies may help or hurt joint gains, depending on a culture's values and norms for power and whether or not power-based influence is used in conjunction with sufficient information exchange. The findings suggest that understanding the other party's cultural characteristics and strategies can help negotiators plan how to focus on information exchange and deal with unusual power strategies that they may encounter.     

Longitudinal Bi-directional Relationships Between Sleep and Youth Substance Use

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.     

The Strategic Use of Interests,Rights, and Power to Resolve Disputes

To ensure success in resolving difficult disputes, negotiators mustmake strategic decisions about their negotiation approach. In this essay,we make practical recommendations for negotiation strategy based on Ury,Brett, and Goldberg's (1993) interests, rights, and power framework fordispute resolution and subsequent empirical research by Brett, Shapiro, andLytle (1998). We discuss how negotiations cycle through interests, rights,and power foci; the prevalence of reciprocity; and the one-sided,distributive outcomes that result from reciprocity of rights and powercommunications. We then turn to using interests, rights and powerstrategically in negotiations. We discuss choosing an opening stragegy,breaking conflict spirals of reciprocated rights and power communications,and when and how to use rights and power communications effectively innegotiations.     

Culture and Joint Gains in Negotiation

What effect does culture have on the achievement of joint gains in negotiation? Prior research has identified a number of strategies, for example sharing information about preferences and priorities, eschewing power, that lead to the development of joint gains when both negotiators are from the U.S. Are these same strategies used in other cultures? Are other strategies used? How effective are negotiators from different cultures in realizing joint gains? These are among the questions considered by the authors, whose research is based on data collected from negotiators from six different cultural backgrounds: France, Russia, Japan, Hong Kong, Brazil, and the U.S.

     

Validation of the PowerPlex 1.1 loci for use in human identification

STR typing is now the favored method of DNA analysis for the purposes of human identification in the forensic community. The Forensic Services Division of the Detroit Police Department has completed its validation of the PowerPlex 1.1 loci (CSF1PO, TPOX, THO1, vWA, D16S539, D7S820, D13S317, and D5S818) for use in forensic casework. Detroit Metro Area Red Cross samples were typed from each of five racial/ethnic groups--the Hispanic, Caucasian, African American, Asian, and American Indian populations--and allele and genotype frequencies were calculated. A rare off-ladder variant (9.1 allele at D7S820) was identified among the database samples. A number of validation studies were performed. DNA was extracted from different substrates and typed as expected, except for the DNA extracted from leather (signal absent from the D16S539, D7S820, D13S317, CSF1PO, and TPOX loci) and from dirt (no PCR product generated). The minor contributor in the mixture study (250 pg input DNA) was facile to discern. The Concordance study, the variety of fluids from the same individual, and NIST standards studies all produced the expected results. Finally, STR data confirmed previous DNA typing results from adjudicated casework samples.
