RESUMO

Pornography use is multidimensional, yet most studies of the topic use variable-oriented methods (e.g., frequency of use) that reduce the experience to a single dimension. In this study, we sought to identify different multidimensional patterns of pornography genre preferences among a sample of women (n = 206) and examine how those patterns are differentially associated with sexual experiences and beliefs examined in previous literature. Latent Class Analysis uncovered four patterns (or classes): Heterogeneous (39%), Traditionally Feminine (27%), Female Pleasure (23%) and Rough/violent (11%). Class membership was differentially predicted by prior sexual victimization, sexual esteem, and diverse sexual experiences while controlling for frequency of use. These findings suggest that genre preference could account for much of the mixed findings of prior work that measured pornography use with unidimensional approaches.

RESUMO

This paper focuses on notions of "addiction" among users of online child sexual exploitation material (CSEM) through a comparative analysis of two qualitative studies. The first is a 17-month anthropological ethnography (participant observation, interviews, and focus groups) in UK group programs for CSEM users, and the second is based on interviews with individuals in sexual offense treatment units of a US prison. We thematically analyze the narratives of 103 CSEM users at different timepoints and settings from pre-trial to incarceration. Those citing "addiction" focused on three areas. First was pornography progression. Second were perceived indicators of "addiction" and alignment/analogy to other addictions, including ideas about losing control; ignoring detrimental consequences and continuing; physiological signs similar to withdrawal; likening to substances; and progression from "softer" to "harder" material. Third, less common was rejecting the "addiction" label, citing choice and responsibility. We situate these results within debates and literature regarding pornography and Internet "addiction"; implications of the label; societal conceptions of sexual offending; harms of CSEM; and treatment/prevention considerations. Lastly, highlighting the merit of interdisciplinary comparative qualitative analysis, we demonstrate similarities in narratives despite differences in location, timeframe, setting, conviction status, intervention programming, and research methods.

RESUMO

This study employs a mixed methods approach, using quantitative analysis to discuss significant patterns, and qualitative analysis to provide descriptive accounts of homicide incidents. Seven hundred and five homicides that occurred in a northeastern city between January 1999 and December 2007 are examined to answer the following research question: Do the situated transactions of firearm homicides differ from those involving other weapons? The quantitative analyses found distinct patterns in offender intent, criminogenic tendencies, and situational attributes between firearm and other weapon homicides. The qualitative analysis revealed that firearms are most often utilized in homicides that can be understood as "doing crime," where offenders and victims are engaged in a criminal lifestyle and firearms are an extension of this activity. Other weapons are associated with homicides concerned with "establishing moral order," or defending values and ideals, between individuals who are intimate. The methodological and policy implication of these findings are discussed.

RESUMO

This study sought to gain insight into the attitudes, beliefs, and values that shape bondage/discipline/sadomasochism (BDSM) activities and to explore the degree and consequences of unintended or non-negotiated harms, including physical, emotional, and sexual violence. A qualitative approach, consisting of 22 semistructured interviews and over 150 hours of observations of BDSM events and activities, was used to develop an in-depth exploration of the lived experiences of participants. Thematic analysis was employed to elucidate the ways in which participants define and in some cases experience harm. Findings suggest that individuals construct rational identities that emphasize safe practices and managing harm; however; there are instances where "boundary slippage" occurs. Implications for understanding the dynamics as well as the potential dangers of "consensual" violence are discussed.

RESUMO

The overwhelming number of male victims of clergy sexual abuse led to assumptions regarding sexual preference of clergy offenders. The present study examined 9,540 records (incidents) of alleged cleric sexual abuse in the United States between 1950 and 1999 to explore situational factors of the abuse by victim gender. No evidence was found to suggest that male victims were purposefully targeted more than female victims; rather, the abuse appeared to be more a function of opportunity. These findings support a situational framework of sexual abuse for the majority of clergy abuse and the assertion that abuse in church can be understood as not a crisis regarding homosexuality but as a social problem that must be examined in its context.

RESUMO

Incels, a portmanteau of the term involuntary celibates, operate in online communities to discuss difficulties in attaining sexual relationships. Past reports have found that multiple elements of the incel culture are misogynistic and favorable towards violence. Further, several violent incidents have been linked to this community, which suggests that incel communities may resemble other ideologically motivated extremist groups. The current study employed an inductive qualitative analysis of over 8,000 posts made in two online incel communities to identify the norms, values, and beliefs of these groups from a subcultural perspective. Analyses found that the incel community was structured around five interrelated normative orders: the sexual market, women as naturally evil, legitimizing masculinity, male oppression, and violence. The implications of this analysis for our understanding of extremism and the role of the internet in radicalization to violence are considered in depth.

RESUMO

Sextortion, a portmanteau of "sexual" and "extortion," is the threat to distribute intimate, sexual materials unless a victim complies with certain demands. Cyber sextortion is part of a larger continuum of image-based sexual offending in which images are used for harm. Despite the serious nature of this crime, there exists a dearth of empirical knowledge of sextortion. This article employed a qualitative content analysis of media articles and court documents to explore the crimes of 152 cyber sextortion offenders. Characteristics of offenders, victims, demands, and methodology were identified and synthesized to generate a qualitative understanding of offenders who employed cyber sextortion. The results revealed four different themes of offenders based on crime characteristics: minor-focused cyber sextortion offenders, cybercrime cyber sextortion offenders, intimately violent cyber sextortion offenders, and transnational criminal cyber sextortion offenders. The diverse nature of cyber sextortion has implications for crime control policies. Certain offenders are more likely to be apprehended and prosecuted depending on the crime victim and methodology. In addition, there has been a lack of legislative action targeting cyber sextortion, which limits legal recourse available for victims. We discuss the contribution of this work to the broader literature on cyber sextortion and address some of the challenges that this crime presents to the criminal justice system.

RESUMO

Despite no definitive relationship between pornography and sexual offenses, there exists an assumption that use plays a role in the commission of sexual crimes and may increase risk of recidivism. This has led to the development of post-release restrictions on adult media for those convicted of a sexual offense. We conducted semi-structured interviews with 101 incarcerated individuals convicted of a sexual offense to explore the central research questions: (1) What are the common themes among individual's experiences regarding pornography and how do they construct the role of pornography in their offending? (2) How do they frame pornography use post-release and understand pornography use as related to risk of re-offense? A qualitative analysis revealed common themes regarding how individuals constructed pornography use and notions of risk. Strategic and targeted monitoring and supervision of those who perceive their pornography use as consuming and facilitating may be a more effective practice than abstinence-only blanket restrictions.

RESUMO

Minimal research has considered the extent to which pedophile social support forum users disclose physical relationships with minors in the course of their posts. As these forums cater to those who express sexual interests in minors, the users may be at higher risk for contact offenses and require unique treatment and supervision. To address this gap in the literature, this study utilized a quantitative analysis of the posts from 806 users from four separate pedophile support forums to identify the correlates of self-disclosed contact with minors. The findings demonstrated that although most users do not disclose physical contact, those who do share several common traits, specifically fantasies of minors, mentions of relationships with minors, and a sexually suggestive username. The implications of this analysis for our understanding of the role of online forums and potential clinical treatment are discussed in detail.

RESUMO

Weight of evidence and biological relevance are important concepts for risk assessment and decision-making over the use of GM crops; however, their meanings are not well defined. We use problem formulation to clarify the definition of these concepts and thereby identify data that are relevant for risk assessment. Problem formulation defines criteria for the acceptability of risk and devises rigorous tests of the hypothesis that the criteria are met. Corroboration or falsification of such hypotheses characterize risk and enable predictable and transparent decisions about whether certain risks from using a particular GM crop are acceptable. Decisions based on a weight of evidence approach use a synthesis of several lines of evidence, whereas a "definitive" approach to risk assessment enables some decisions to be based on the results of a single test. Data are biologically relevant for risk assessment only if they test a hypothesis that is useful for decision-making.

RESUMO

The agronomic and pulping performance of transgenic trees with altered lignin has been evaluated in duplicated, long-term field trials. Poplars expressing cinnamyl alcohol dehydrogenase (CAD) or caffeate/5-hydroxy-ferulate O-methyltransferase (COMT) antisense transgenes were grown for four years at two sites, in France and England. The trees remained healthy throughout the trial. Growth indicators and interactions with insects were normal. No changes in soil microbial communities were detected beneath the transgenic trees. The expected modifications to lignin were maintained in the transgenics over four years, at both sites. Kraft pulping of tree trunks showed that the reduced-CAD lines had improved characteristics, allowing easier delignification, using smaller amounts of chemicals, while yielding more high-quality pulp. This work highlights the potential of engineering wood quality for more environmentally benign papermaking without interfering with tree growth or fitness.

RESUMO

Chromosome deletions in the mouse have proven invaluable in the dissection of gene function. The brown deletion complex comprises >28 independent genome rearrangements, which have been used to identify several functional loci on chromosome 4 required for normal embryonic and postnatal development. We have constructed a 172-bacterial artificial chromosome contig that spans this 22-megabase (Mb) interval and have produced a contiguous, finished, and manually annotated sequence from these clones. The deletion complex is strikingly gene-poor, containing only 52 protein-coding genes (of which only 39 are supported by human homologues) and has several further notable genomic features, including several segments of >1 Mb, apparently devoid of a coding sequence. We have used sequence polymorphisms to finely map the deletion breakpoints and identify strong candidate genes for the known phenotypes that map to this region, including three lethal loci (l4Rn1, l4Rn2, and l4Rn3) and the fitness mutant brown-associated fitness (baf). We have also characterized misexpression of the basonuclin homologue, Bnc2, associated with the inversion-mediated coat color mutant white-based brown (B(w)). This study provides a molecular insight into the basis of several characterized mouse mutants, which will allow further dissection of this region by targeted or chemical mutagenesis.

RESUMO

Transgenic plants severely suppressed in the activity of cinnamoyl-CoA reductase were produced by introduction of a partial sense CCR transgene into tobacco. Five transgenic lines with CCR activities ranging from 2 to 48% of wild-type values were selected for further study. Some lines showed a range of aberrant phenotypes including reduced growth, and all had changes to lignin structure making the polymer more susceptible to alkali extraction. The most severely CCR-suppressed line also had significantly decreased lignin content and an increased proportion of free phenolic groups in non-condensed lignin. These changes are likely to make the lignin easier to extract during chemical pulping. Direct Kraft pulping trials confirmed this. More lignin could be removed from the transgenic wood than from wild-type wood at the same alkali charge. A similar improvement in pulping efficiency was recently shown for poplar trees expressing an antisense cinnamyl alcohol dehydrogenase gene. Pulping experiments performed here on CAD-antisense tobacco plants produced near-identical results--the modified lignin was more easily removed during pulping without any adverse effects on the quality of the pulp or paper produced. These results suggest that pulping experiments performed in tobacco can be predictive of the results that will be obtained in trees such as poplar, extending the utility of the tobacco model. On the basis of our results on CCR manipulation in tobacco, we predict that CCR-suppressed trees may show pulping benefits. However, it is likely that CCR-suppression will not be the optimal target for genetic manipulation of pulping character due to the potential associated growth defects.
