Integrating a domestic violence education program into a medical school curriculum: challenges and strategies.

BACKGROUND: Domestic violence affects millions of women in the United States each year. Physicians are in a unique position to screen for violence in their patients' homes and refer individuals before they are injured or killed. All U.S. medical schools are expected to incorporate partner violence into their curricula. DESCRIPTION: The MCP Hahnemann School of Medicine has developed and integrated a domestic violence educational intervention program into the existing problem-based medical school curriculum. This educational intervention includes modification of an existing teaching case to include signs and symptoms specific to domestic violence, written learning objectives on domestic violence in the health care setting, relevant resource material, and a 3-hr training program conducted by an interdisciplinary teaching team. EVALUATION: Based on quantitative and qualitative data over a 3-year period, this domestic violence education program has been successfully integrated into an existing problem-based curriculum. Overall, the high student exam scores indicate the effectiveness of the teaching program. In addition, the students' evaluation of the program reflects a high level of student satisfaction with the curriculum presented on domestic violence. CONCLUSION: This article describes both the content of a domestic violence teaching program and the process used to integrate such a program into a medical school curriculum. Although medical schools and their teaching programs are uniquely structured, with slight modifications they are able to accommodate domestic violence teaching programs.

Postdeployment domestic violence by U.S. Army soldiers.

The objective of this study was to determine whether a military deployment of 6 months predicted domestic violence against the wives of deployed and nondeployed soldiers during the postdeployment period. The method involved the completion of an anonymous questionnaire by a sample of the spouses of soldiers deployed from a large U.S. Army post. The Conflict Tactics Scale identified incidents of domestic violence by the soldier husbands, and a logistic regression model predicted domestic violence during the postdeployment period. The results indicate that deployment was not a significant predictor of domestic violence during the first 10 months of the postdeployment period. Younger wives and those who were victims of predeployment domestic violence were more likely to report postdeployment domestic violence. The conclusion was that interventions for domestic violence in the U.S. Army should address risks among younger couples and those with a previous incident of domestic violence.

Child protective services and domestic violence.

Studies estimate that domestic violence is present in at least one-third of the families involved in child protective services (CPS). Yet, until recently, CPS has not directly addressed domestic violence in its handling of child abuse and neglect cases. By the same token, domestic violence programs have historically emphasized services for battered women, with limited understanding of the child safety goals of CPS. Despite these historical differences, collaborative efforts between CPS and domestic violence service programs are emerging based on a common goal of safety from violence for all family members. Innovative strategies include the use of domestic violence specialists in a variety of child protection settings for case consultation and for support to the battered women, direct referrals of battered women from domestic violence programs to family preservation services, and cross-training of CPS workers and domestic violence service providers. A survey of state CPS administrators and domestic violence coalition directors conducted for this article revealed that although there is mutual interest in greater collaboration, such efforts remain limited. New forums, such as CPS citizen review panels and community-based CPS partnerships, hold promise for further collaboration. Critical to successful strategies are supportive agency leadership, greater trust and understanding across systems, a recognition of common goals, and a willingness to change policies and practice.

Community-based domestic violence services.

Community-based domestic violence services have grown significantly since their emergence in the 1970s. Now more than 2,000 in number, domestic violence organizations have expanded their range of programs. In addition to crisis-oriented services, such as telephone hot lines and temporary shelter, many of these agencies provide legal, health, mental health, or vocational services or referrals, and assistance in finding housing, relocating, and planning for safety. Most recently, in response to increasing knowledge about the deleterious effects of exposure to domestic violence on children, community-based service providers have developed programs addressing children's mental health, health, educational, and safety needs. This article describes and analyzes trends in service delivery by these community-based organizations to children affected by domestic violence. It concludes that, although there has been significant growth in services, substantial segments of the target population still are not reached, and most organizations do not yet have a sufficient range of services to meet children's diverse needs. Challenges posed by inadequate funding, needs for specialized staffing, and a dearth of data on the efficacy of current intervention programs hamper domestic violence service providers' ability to meet children's needs. However, this article highlights promising new directions in service delivery. Community-based domestic violence organizations increasingly are using innovative strategies to address children's service needs. These agencies are expanding community outreach efforts and attempts to educate the public and professionals about domestic violence and children. In addition, these organizations are building important collaborative relationships with other agencies concerned with children's welfare, such as child protective services, law enforcement, schools, and health care facilities. These and related developments suggest cautious optimism that future years will see continuing progress in attempts by community-based organizations to address the needs of children whose well-being is jeopardized by their exposure to domestic violence.

Domestic violence and the criminal justice system: an overview.

It is only recently that domestic violence has been considered a violation of the law. Although men have battered, abused and mistreated their wives or intimate partners for a long time, historically, wife or partner abuse has been viewed as a "normal" part of marriage or intimate relationships. Only towards the end of the twentieth century, in the 1970 s, has domestic violence been defined a crime, justifying intervention by the criminal justice system. This article surveys the history of domestic violence as a criminal offense, and the justice system response to woman battering incidents. It first discusses the definition of the offense including debates around the offense definition, and the prevalence and reported frequency of the behavior termed woman battering. It then reviews the legal and social changes over time that have altered the criminal justice system s approach to domestic violence. Next it outlines the responses of the police, and the prosecution of domestic violence. The article also discusses research findings related to domestic violence and the criminal justice system, along with current controversies concerning the justice approach to domestic violence, its law enforcement, and related unfolding trends in the movement to address domestic violence through the criminal justice system.

Midwives' perceptions and experiences of routine enquiry for domestic violence.

OBJECTIVE: To examine midwives' perceptions and experiences of routine enquiry for domestic violence. DESIGN: Focus groups and semi-structured interviews. SETTING: The study was conducted in the maternity services of Guy's and St Thomas' NHS Hospital Trust, an inner London teaching hospital. SAMPLE: Twenty-eight midwives were interviewed. METHODS: One hundred and sixteen out of 145 (80%) midwives were trained to screen routinely pregnant women for domestic violence at booking, at 34 weeks of gestation and postpartum. Twenty midwives attended one of four focus groups and eight semi-structured interviews were conducted. Interviews were transcribed and analysed using content analysis. MAIN OUTCOME MEASURES: Midwives' views of routine enquiry for domestic violence. RESULTS: Midwives felt that domestic violence was an important issue to be addressed. However, practical and personal difficulties were encountered during the study. These included: time constraints, lack of confidential time, safety issues, staff shortages, low staff morale and midwives' personal experiences of domestic violence. The study produced a raised awareness about domestic violence within the maternity unit. There was considerable support for the idea of a specialist domestic violence midwife. CONCLUSIONS: Routine enquiry for domestic violence cannot be implemented effectively without ensuring that in-depth training, resources, staff support and policies to ensure that screening can be conducted safely and confidentially are in place.

Recognising domestic violence in clinical practice using the diagnoses of posttraumatic stress disorder, depression and low self-esteem.

This discussion paper reviews the health impacts, physical and mental, of domestic violence and explores the link between domestic violence and psychological symptoms. This paper focuses more on posttraumatic stress disorder (PTSD) than depression and low self-esteem because doctors are less familiar with PTSD. The barriers preventing health workers from detecting domestic violence are reviewed and the fear of health professionals that asking about trauma can harm patients is explored. The article then outlines practical strategies to improve detection of domestic violence using patients' presenting psychological symptoms and the diagnoses frequently associated with domestic violence namely, PTSD, depression and low self-esteem. It is argued that it is inadvisable to try to implement a policy of screening for domestic violence in general practice when the public health model is currently inappropriate. The paper discusses why the diagnostic frameworks of depression and PTSD are helpful in general practice, not only in detecting domestic violence but in working with the patient to establish trust and ways forward that can be tailored to meet the needs of the patient and their children. Patients' and professionals' dilemmas about what to do once domestic violence is detected are briefly explored.

From wild to domestic: Single-cell transcriptomic perspectives on hippocampal regulation and evolution.

How domestication shapes brain evolution remains an open question. In this study, we integrated single-nucleus RNA sequencing (snRNA-seq), population genomics, and machine learning to investigate the hippocampal evolution under domestication. Across-species comparisons revealed that hippocampal cell type profiles are largely conserved across vertebrate species, while supporting the presence of adult hippocampal neurogenesis in birds. We further found that domestication and selective breeding likely influence the cellular composition and molecular regulation of the hippocampus. Our findings provide cellular evidence supporting the hypothesis that domestication affects adult hippocampal neurogenesis. Additionally, we showed that genes associated with neural progenitor cells (NPC) states and cell-marker programs are enriched for signatures of selection. Many of these genes function as regulators of neurogenesis and pathways mediating stress and fear reduction. Specifically, we identified selection at the FKBP5 promoter that may influence its expression in the NPC lineage, potentially contributing to stress-response regulation during domestication. Collectively, these results suggest that domestication is associated with hippocampal remodeling as part of an adaptive response to human-managed environments. This study provides a cellular and genetic perspective on how domestication reshapes the brain and offers a basis for further investigation into the mechanisms of neural evolution within the context of microevolution.

Asymmetry of gene flow and differential geographical structure of molecular diversity in wild and domesticated common bean (Phaseolus vulgaris L.) from Mesoamerica.

Using amplified fragment length polymorphisms (AFLPs), we analyzed the genetic structure of wild and domesticated common bean (Phaseolus vulgaris L.) from Mesoamerica at different geographical levels to test the hypothesis of asymmetric gene flow and investigate the origin of weedy populations. We showed both by phenetic and admixture population analyses that gene flow is about three- to four-fold higher from domesticated to wild populations than in the reverse direction. This result, combined with other work, points to a displacement of genetic diversity in wild populations due to gene flow from the domesticated populations. The weedy populations appear to be genetically intermediate between domesticated and wild populations, suggesting that they originated by hybridization between wild and domesticated types rather than by escape from cultivation. In addition, the domesticated bean races were genetically similar confirming a single domestication event for the Mesoamerican gene pool. Finally, the genetic diversity of the domesticated bean population showed a lower level of geographic structure in comparison to that of the wild populations.

AFLP analysis of the phenetic organization and genetic diversity of Vigna unguiculataL. Walp. reveals extensive gene flow between wild and domesticated types.

Amplified fragment length polymorphisms (AFLPs) were used to evaluate genetic relationships within cowpea [ Vigna unguiculata (L.) Walp.] and to assess the organization of its genetic diversity. Nei's genetic distances were estimated for a total of 117 accessions including 47 domesticated cowpea (ssp. unguiculata var. unguiculata), 52 wild and weedy annuals (ssp. unguiculata var. spontanea), as well as 18 perennial accessions of the wild subspecies pubescens, tenuis and alba. AFLP variation was also used to study genetic variation among and within domesticated and wild accessions based on their geographical origin (western, eastern and southern Africa). Wild annual cowpea (var. spontanea) ( H (T)=0.175) was more diverse than domesticated cowpea ( H (T)=0.108). Wild cowpea was more diverse in eastern ( H (S)=0.168) than in western Africa ( H (S)=0.129), suggesting an eastern African origin for the wild taxon. The AFLP data were consistent with earlier findings of a unique domestication event in cowpea in the northern part of the continent and suggested that domestication in eastern or southern Africa was unlikely. It did not allow a more precise localization of domestication due to extensive gene flow between wild and domesticated forms that has led to a large crop-weed complex distributed over the entire African continent. In addition, wild materials from northeastern Africa are still lacking. Overall, the superiority of the AFLP technique over isozymes resided in its ability to uncover variation both within domesticated and wild cowpea, and should be a powerful tool once additional wild material becomes available.

Place and matching-to-place spatial learning affected by rat inbreeding (Dark-Agouti, Fischer 344) and albinism (Wistar, Sprague-Dawley) but not domestication (wild rat vs. Long-Evans, Fischer-Norway).

Domestication has been shown to produce a shift in both morphological and behavioral characteristics of animals. While changes in body weight, brain size, reproductive rates, and temperament are well documented, the effects of domestication on learning and memory are not as clearly understood. This issue is of particular importance to the use of rodent models in learning and memory where the domestication of Rattus norvegicus for research has resulted in the availability of numerous strains. To investigate cognitive effects resulting frm domestication, we examined the spatial performance of a number of rat strains: wild, Long-Evans, Fischer-Norway, Dark-Agouti, Wistar, Fischer 344, Sprague-Dawley. The wild rats served as a baseline for comparing inbred and outbred domestic strains and pigmented and albino domestic strains. Place (a measure of nonspatial and procedural learning), matching-to-place (spatial working memory), and probe (retention) performance were measured in the Morris swimming pool task. The task is an ideal means for comparing different rat strains because place learning has not been selected for in the domestication of Rattus norvegicus and because the task is ethologically relevant. The results indicated that wild rats and Long-Evans rats did not differ on any measure, with Fischer-Norway rats being only slightly inferior. Larger impairments were found in Wistar > Fischer 344 > Dark-Agouti > Sprague-Dawley strains. Impairments were more obvious on place acquisition but also occurred in matching-to-place performance. Platform crosses, but not quadrant preference was found to be correlated with place learning. In general, although nonspatial and spatial deficits were associated with both inbreeding and albinism, impaired spatial performance is not a necessary result of domestication.

Factors affecting the flow among domestic, synanthropic and sylvatic cycles of Trichinella.

Nematodes of the genus Trichinella are maintained in nature by sylvatic or domestic cycles. The sylvatic cycle is widespread on all continents, from frigid to torrid zones, and it is maintained by cannibalism and scavenging behavior of carnivores. Trichinella is primarily a parasite of carnivorous mammals, although one non-encapsulated species, Trichinella pseudospiralis, has also been detected in birds. The anaerobic metabolism of larvae in nurse cells allows their survival in extremely decayed meat. Encapsulated larvae in the decomposing carcass function similarly to the species-dispersing population of eggs or larvae of other nematodes, suggesting that the natural cycle of Trichinella includes a free-living stage when the parasite is no longer protected by the homeothermy of the host. Consequently, environmental temperature and humidity play an important role in the transmission of Trichinella among wildlife. Of the 10 recognized genotypes of Trichinella, only Trichinella spiralis is transmitted and maintained in a domestic cycle, although it can be present also in wildlife. All other genotypes (Trichinella nativa, Trichinella britovi, T. pseudospiralis, Trichinella murrelli, Trichinella nelsoni and Trichinella papuae, Trichinella T6, T8, and T9) are transmitted and maintained only in a sylvatic cycle. This generalization does not preclude sylvatic species of Trichinella from invading the domestic habitat, and T. spiralis may return to this habitat when humans fail in the management of wildlife and domestic animals. However, the presence of sylvatic genotypes of Trichinella in the domestic habitat represents a "dead-end" for the sylvatic cycle. Synanthropic animals (rats, foxes, mustelids, cats, dogs, etc.) contribute to the flow of sylvatic Trichinella genotypes from wildlife to domestic animals and of T. spiralis from domestic to sylvatic animals. Furthermore, human behavior not only influences the transmission patterns of Trichinella genotypes in the domestic habitat, but also it can contribute to the transmission and spread of this infection among wildlife, for example by improper hunting practices.

Instrument development and evaluation of domestic preparedness training for first responders.

INTRODUCTION: In the wake of domestic terrorists attacks on 11 September 2001 and subsequent bioterrorist events employing anthrax, there no longer can be any debate about the potential for attacks employing Nuclear, Biological, or Chemical (NBC)/Weapons of Mass Destruction (WMD). As one way of acknowledging this long-standing threat and, in a concerted effort to mitigate the effects of possible future domestic NBC/WMD terrorist attacks, the US Department of Defense (DOD) and other US governmental agencies already had mounted an effort to provide Domestic Preparedness Training for First Responders in urban centers throughout the USA. METHODS: A paper and pencil questionnaire specifically designed to evaluate the effectiveness of Domestic Preparedness Training for Emergency First Responders has been developed. An earlier version of this instrument was piloted with a convenience sample of firefighters and paramedics (n = 78) in a northwest state. Based on replies to the pilot questionnaire, a pool of 27 items based on the objectives and content of the NBC/WMD Domestic Preparedness Awareness and Operations courses (plus additional background and appraised competency items) were selected for inclusion in a Domestic Preparedness Questionnaire (DPQ). RESULTS: This paper first describes the essential psychometric properties of the DPQ based on replies from baseline and follow-up samples (n = 206 and n = 246 respectively) of urban firefighters and paramedics employed by a metropolitan city in a northwest state. The DPQ was employed to evaluate the outcomes of Domestic Preparedness training provided to a sample of urban fire-service personnel. The DPQ documented significant improvements in a group of "DP trained"-urban firefighters (n = 80) both in their awareness and operations content knowledge as well as in their perceived competencies to respond to acts of biological, chemical, or nuclear terrorism "in their own community" at four months post-training. A comparison group of "Not DP-trained" firefighters (n = 78) showed no statistically significant changes on these DPQ indices, suggesting that the documented improvements in the "DP-trained" firefighters on the DPQ were not due to "test reactivity" or to "historical" factors. CONCLUSION: The findings suggest that the DPQ has adequate inter-item and test-retest reliability, possesses concurrent validity, and appears to be a sensitive measure of the Domestic Preparedness Training provided for urban firefighter and paramedic First Responders.

Genetic divergence between Cyprinus carpio carpio and Cyprinus carpio haematopterus as assessed by mitochondrial DNA analysis, with emphasis on origin of European domestic carp.

Although common carp is the major fish species in Asian and European aquaculture and many domestic varieties have occurred, there is a controversy about the origination of European domestic common carp. Some scientists affirmed that the ancestor of European domestic common carp was Danube River wild common carp, but others considered it might be Asian common carp. For elucidating origination of European domestic common carp, we chose two representative European domestic common carp strains (German mirror carp and Russian scattered scaled mirror carp) and one wild common carp strain of Cyprinus carpio carpio subspecies (Volga River wild common carp) and two Asian common carp strains, the Yangtze River wild common carp (Cyprinus carpio haematopterus) and traditionally domestic Xingguo red common carp, as experimental materials. ND5-ND6 and D-loop segments of mitochondrial DNA were amplified by polymerase chain reaction and analyzed through restriction fragment length polymorphism (RFLP) and sequencing respectively. The results revealed that HaeIII and DdeI digestion patterns of ND5-ND6 segment and sequences of control region were different between European subspecies C. carpio carpio and Asian subspecies C. carpio haematopterus. Phylogenetic analysis showed that German mirror carp and Russian scattered scaled mirror carp belonged to two subspecies, C. carpio carpio and C. carpio haematopterus, respectively. Therefore, there were different ancestors for domestic carp in Europe: German mirror carp was domesticated from European subspecies C. carpio carpio and Russian scattered scaled mirror carp originated from Asian subspecies C. carpio haematopterus.

Origin of extant domesticated sunflowers in eastern North America.

Eastern North America is one of at least six regions of the world where agriculture is thought to have arisen wholly independently. The primary evidence for this hypothesis derives from morphological changes in the archaeobotanical record of three important crops--squash, goosefoot and sunflower--as well as an extinct minor cultigen, sumpweed. However, the geographical origins of two of the three primary domesticates--squash and goosefoot--are now debated, and until recently sunflower (Helianthus annuus L.) has been considered the only undisputed eastern North American domesticate. The discovery of 4,000-year-old domesticated sunflower remains from San Andrés, Tabasco, implies an earlier and possibly independent origin of domestication in Mexico and has stimulated a re-examination of the geographical origin of domesticated sunflower. Here we describe the genetic relationships and pattern of genetic drift between extant domesticated strains and wild populations collected from throughout the USA and Mexico. We show that extant domesticates arose in eastern North America, with a substantial genetic bottleneck occurring during domestication.

Estimating the long-term effects of stocking domesticated trout into wild brown trout (Salmo trutta) populations: an approach using microsatellite DNA analysis of historical and contemporary samples.

Indigenous salmonid fish gene pools are affected by domesticated conspecifics, derived from aquaculture escapes and deliberate releases. Variability was examined at nine microsatellite loci in order to assess the long-term impact of stocking domesticated trout in two brown trout populations. The study was based on analysis of two historical samples (1945-56), represented by old scale collections, and seven contemporary samples (1986-2000). In one population historical and contemporary samples were remarkably genetically similar despite more than a decade of intense stocking. Estimation of admixture proportions showed a small genetic contribution from domesticated trout (approximately 6%), and individual admixture analysis demonstrated a majority of nonadmixed individuals. The expected genetic contribution by domesticated trout was 64%, assessed from the number of stocked trout and assuming equal survival and reproductive performance of wild and domesticated trout. This demonstrates poor performance and low fitness of domesticated trout in the wild. In another population there was a strong genetic contribution from domesticated trout (between 57% and 88% in different samples), both in samples from a broodstock thought to represent the indigenous population and in a sample of wild spawners. Survival of domesticated trout and admixture with indigenous fish in the broodstock and subsequent stocking into the river, combined with a low population size of native trout relative to the number of stocked trout, could explain the observed introgression. Few nonadmixed individuals remained in the introgressed population, and I discuss how individual admixture analysis can be used to identify and conserve nonintrogressed remains of the population.

Addressing domestic violence through maternity services: policy and practice.

OBJECTIVE: to explore current policies and practices in maternity units that aim to identify, assess and support women experiencing domestic violence. DESIGN AND SETTING: a postal survey, conducted between June and October 1999, of all NHS Trusts in England and Wales that provided maternity services. PARTICIPANTS: Heads of Midwifery or the midwife with expertise or interest in domestic violence in each Trust. MAIN OUTCOME MEASURES: use of written policies and agreed practices for identifying and referring women experiencing domestic violence, such as availability of information, routine questioning of all women and offering women an appointment without their partner. RESULTS: 87% (183) of the 211 NHS Trusts providing maternity care participated in the survey. Twelve per cent of units had written policies for identifying women experiencing domestic violence, and a further 30% had some form of agreed practice. Less than half of maternity units routinely offered women an appointment without their partner, and just over half displayed material about domestic violence in places where women receive maternity care. Only three units had undertaken audit on their domestic violence practices. CONCLUSIONS: there is considerable variability around England and Wales in policies and practices related to domestic violence. It is evident that clear guidelines for identification and referral, training, audit and the integration of domestic violence policies with child protection and other policies are necessary to fully address the issues.

Phylogenetic relationships among domesticated and wild species of Cucurbita (Cucurbitaceae) inferred from a mitochondrial gene: Implications for crop plant evolution and areas of origin.

We have investigated the phylogenetic relationships among six wild and six domesticated taxa of Cucurbita using as a marker an intron region from the mitochondrial nad1 gene. Our study represents one of the first successful uses of a mtDNA gene in resolving inter- and intraspecific taxonomic relationships in Angiosperms and yields several important insights into the origins of domesticated Cucurbita. First, our data suggest at least six independent domestication events from distinct wild ancestors. Second, Cucurbita argyrosperma likely was domesticated from a wild Mexican gourd, Cucurbita sororia, probably in the same region of southwest Mexico that gave rise to maize. Third, the wild ancestor of Cucurbita moschata is still unknown, but mtDNA data combined with other sources of information suggest that it will probably be found in lowland northern South America. Fourth, Cucurbita andreana is supported as the wild progenitor of Cucurbita maxima, but humid lowland regions of Bolivia in addition to warmer temperate zones in South America from where C. andreana was originally described should possibly be considered as an area of origin for C. maxima. Fifth, our data support other molecular results that indicate two separate domestications in the Cucurbita pepo complex. The potential zone of domestication for one of the domesticated subspecies, C. pepo subsp. ovifera, includes eastern North America and should be extended to northeastern Mexico. The wild ancestor of the other domesticated subspecies, C. pepo subsp. pepo, is undiscovered but is closely related to C. pepo subsp. fraterna and possibly will be found in southern Mexico.
