Psychological treatment of problematic sexual interests: cross-country comparison

This paper reviews the use of psychotherapeutic approaches to treat individuals who have committed sex crimes and/or have problematic sexual interests (PSI); including types of psychotherapy used, descriptions of preventive and reintegration programs and highlighting specific theoretical controversies. In the second part, experts from Canada, Czech Republic, Russia, United Kingdom, and the United States, who participated in an International Consensus Meeting held in Prague (2017), summarize treatment programs in their countries. The comparison revealed some general findings: each country has variability between its own programs; most countries have different programs for people who are in custody and who are in the community; the state-directed treatment programs are primarily focused on criminal individuals while non-criminal individuals are treated in preventive programs and/or in special clinics or are non-treated; the presence of PSI in patients/clients is acknowledged in most programs, although specific programs exclusively for individuals with PSI rarely exist. Studies on effectiveness are difficult to compare due to methodologic, political and cultural differences. Further communication between more countries to share knowledge about successful treatments and preventive approaches is needed, especially enhanced international collaboration between researchers and clinicians to verify the effectiveness of current clinical and experimental programs

The influence of implicit theories and offender characteristics on judgements of sexual offenders: a moderated mediation analysis

The psychological factors underpinning responses to sexual offenders are beginning to receive increased empirical scrutiny. One such factor is offender representativeness, which refers to the extent to which a given offender example matches a stereotype of those who are typically labelled as 'sexual offenders'. Using a sample of 252 community members, we examined the role of implicit theories about sexual offenders (i.e., whether sexual offending is seen as fixed or malleable) in mediating the relationship between affective responses to sexual offenders and policy outcome judgements. We found support for this mediating effect, although this was eliminated when participants were presented with a 'non-representative' offender vignette. We argue that the relationship between affective responses and policy judgements is contingent on the activation of a sexual offender stereotype, and that this link can be disrupted via the increased presentation of non-stereotypical case examples. Implications for public debate and professional practice are discussed

Implicit theories and offender representativeness in judgments about sexual crime

Implicit theories structure the way people understand and respond to various human actions. Typically, people believe attributes are either fixed (entitists) or malleable (incrementalists). The present study aimed to examine: (a) whether attitudes towards sexual offenders differ depending upon one’s implicit theory about human nature and sexual offenders, and (b) whether implicit theories are associated with judgments made about different types of child abuser. A sample of 252 community participants was recruited. Their attitudes, implicit theories, and political orientation were assessed via self-report. One of three vignettes describing an incidence of child sexual abuse was then presented. The cases were identical except the perpetrator was either an adult male, an adult female, or a male juvenile. Participants then made judgments about the offender's deserved sentence and moral character. Entitists (across both domains) held more negative attitudes than incrementalists, although the magnitude of the difference was greatest when examining implicit theories about sexual offenders. Compared to those with an incremental theory of sexual offenders, entity theorists judged sexual offending to be more: (a) indicative of the perpetrator’s moral character, and (b) deserving of punishment. However, scores were greater towards the adult male relative to the adult female and juvenile. The findings suggest that implicit theories about sexual offenders are domain-specific. They also indicate that judgments made by those with an entity theory (about sexual offenders) are affected by whether a case is representative of a stereotypical sexual offender. Implications of the findings are discussed, along with limitations and future research

A comparative study of Tam3 and Ac transposition in transgenic tobacco and petunia plants

Transposition of the Anthirrinum majus Tam3 element and the Zea mays Ac element has been monitored in petunia and tobacco plants. Plant vectors were constructed with the transposable elements cloned into the leader sequence of a marker gene. Agrobacterium tumefaciens-mediated leaf disc transformation was used to introduce the transposable element constructs into plant cells. In transgenic plants, excision of the transposable element restores gene expression and results in a clearly distinguishable phenotype. Based on restored expression of the hygromycin phosphotransferase II (HPTII) gene, we established that Tam3 excises in 30% of the transformed petunia plants and in 60% of the transformed tobacco plants. Ac excises from the HPTII gene with comparable frequencies (30%) in both plant species. When the β-glucuronidase (GUS) gene was used to detect transposition of Tam3, a significantly lower excision frequency (13%) was found in both plant species. It could be shown that deletion of parts of the transposable elements Tam3 and Ac, removing either one of the terminal inverted repeats (TIR) or part of the presumptive transposase coding region, abolished the excision from the marker genes. This demonstrates that excision of the transposable element Tam3 in heterologous plant species, as documented for the autonomous element Ac, also depends on both properties. Southern blot hybridization shows the expected excision pattern and the reintegration of Tam3 and Ac elements into the genome of tobacco plants.

Radically Rethinking Agriculture for the 21st Century

Population growth, arable land and fresh water limits, and climate change have profound implications for the ability of agriculture to meet this century’s demands for food, feed, fiber, and fuel while reducing the environmental impact of their production. Success depends on the acceptance and use of contemporary molecular techniques, as well as the increasing development of farming systems that use saline water and integrate nutrient flows

Tracing the Evolution of the Floral Homeotic B- and C-Function Genes through Genome Synteny

The evolution of the floral homeotic genes has been characterized using phylogenetic and functional studies. It is possible to enhance these studies by comparing gene content and order between species to determine the evolutionary history of the regulatory genes. Here, we use a synteny-based approach to trace the evolution of the floral B- and C-function genes that are required for specification of the reproductive organs. Consistent with previous phylogenetic studies, we show that the euAP3–TM6 split occurred after the monocots and dicots diverged. The Arabidopsis TM6 and papaya euAP3 genes are absent from the respective genomes, and we have detected loci from which these genes were lost. These data indicate that either the TM6 or the euAP3 lineage genes can be lost without detriment to flower development. In contrast, PI is essential for male reproductive organ development; yet, contrary to predictions, complex genomic rearrangements have resulted in almost complete breakdown of synteny at the PI locus. In addition to showing the evolution of B-function genes through the prediction of ancestral loci, similar reconstructions reveal the origins of the C-function AG and PLE lineages in dicots, and show the shared ancestry with the monocot C-function genes. During our studies, we found that transposable elements (TEs) present in sequenced Antirrhinum genomic clones limited comparative studies. A pilot survey of the Antirrhinum data revealed that gene-rich regions contain an unusually high degree of TEs of very varied types, which will be an important consideration for future genome sequencing efforts

Genomic repeat abundances contain phylogenetic signal

A large proportion of genomic information, particularly repetitive elements, is usually ignored when researchers are using next-generation sequencing. Here we demonstrate the usefulness of this repetitive fraction in phylogenetic analyses, utilizing comparative graph-based clustering of next-generation sequence reads, which results in abundance estimates of different classes of genomic repeats. Phylogenetic trees are then inferred based on the genome-wide abundance of different repeat types treated as continuously varying characters; such repeats are scattered across chromosomes and in angiosperms can constitute a majority of nuclear genomic DNA. In six diverse examples, five angiosperms and one insect, this method provides generally well-supported relationships at interspecific and intergeneric levels that agree with results from more standard phylogenetic analyses of commonly used markers. We propose that this methodology may prove especially useful in groups where there is little genetic differentiation in standard phylogenetic markers. At the same time as providing data for phylogenetic inference, this method additionally yields a wealth of data for comparative studies of genome evolution

Identifying the needs of brain tumor patients and their caregivers

The purpose of this study is to identify the needs of brain tumor patients and their caregivers to provide improved health services to these populations. Two different questionnaires were designed for patients and caregivers. Both questionnaires contained questions pertaining to three realms: disease symptoms/treatment, health care provider, daily living/finances. The caregivers’ questionnaires contained an additional domain on emotional needs. Each question was evaluated for the degree of importance and satisfaction. Exploratory analyses determined whether baseline characteristics affect responder importance or satisfaction. Also, areas of high agreement/disagreement in satisfaction between the participating patient-caregiver pairs were identified. Questions for which >50% of the patients and caregivers thought were “very important” but >30% were dissatisfied include: understanding the cause of brain tumors, dealing with patients’ lower energy, identifying healthful foods and activities for patients, telephone access to health care providers, information on medical insurance coverage, and support from their employer. In the emotional realm, caregivers identified 9 out of 10 items as important but need further improvement. Areas of high disagreement in satisfaction between participating patient-caregiver pairs include: getting help with household chores (P value = 0.006) and finding time for personal needs (P value < 0.001). This study provides insights into areas to improve services for brain tumor patients and their caregivers. The caregivers’ highest amount of burden is placed on their emotional needs, emphasizing the importance of providing appropriate medical and psychosocial support for caregivers to cope with emotional difficulties they face during the patients’ treatment process

Mitoxantrone and Analogues Bind and Stabilize i-Motif Forming DNA Sequences

YesThere are hundreds of ligands which can interact with G-quadruplex DNA, yet very few which target i-motif. To appreciate an understanding between the dynamics between these structures and how they can be affected by intervention with small molecule ligands, more i-motif binding compounds are required. Herein we describe how the drug mitoxantrone can bind, induce folding of and stabilise i-motif forming DNA sequences, even at physiological pH. Additionally, mitoxantrone was found to bind i-motif forming sequences preferentially over double helical DNA. We also describe the stabilisation properties of analogues of mitoxantrone. This offers a new family of ligands with potential for use in experiments into the structure and function of i-motif forming DNA sequences
