Public's and police officers' interpretation and handling of domestic violence cases: divergent realities.

The public's and police officers'interpretation and handling of realistic hypothetical domestic violence cases and their stereotypic views about domestic violence are discussed. A sample of 131 experienced officers, 127 novice officers, and 157 adult laypersons were randomly assigned to read a domestic violence case. Experienced officers were more likely to arrest only the husband than were laypersons or rookie officers even when respondents inferred that the husband was primarily responsible or had used violence before. Experienced officers considered their stereotypic beliefs about battered women's propensity to use self-defense in arriving at their arrest decision whereas laypersons and rookie officers did not. These findings indicate that the public and police officers have not adopted the feminists' message that arrest is the best response to handle all domestic violence cases. Policy implications are discussed.

Relinquishing the need to "fix it": medical intervention with domestic abuse.

The grounded theory method was used to study obstetricians/gynecologists' interactions with victims of domestic abuse. Double-bind conflict emerged as the basic social psychological problem. Physicians struggled between approaching domestic abuse as a legitimate medical problem or retreating from it as an overwhelming social issue. Resolution occurred through a three-stage process that changed the doctors' objective from "fixing" the abuse to supporting the patient. This goal revision required education on the dynamics of domestic abuse, confrontation of personal issues, and formation of community partnerships. Implications include development of curricula and protocols to create a united front against domestic abuse within health care, social service, legal, and law enforcement communities.

Short-term respiratory effects of cleaning exposures in female domestic cleaners.

Symptoms of obstructive lung disease in domestic cleaners have been related to the use of bleach and other irritant cleaning products. The short-term effects of cleaning exposures on respiratory symptoms and peak expiratory flow (PEF) were investigated in domestic cleaners with respiratory disorders. In a panel study, 43 female domestic cleaners with a recent history of asthma and/or chronic bronchitis completed a 2-week diary, collecting information on respiratory symptoms, PEF and cleaning exposures. Mixed regression models were used to assess daily changes in symptoms and PEF associated with specific cleaning exposures. The probability of having work-related asthma was individually assessed by a computerised diagnostic system and an occupational asthma expert. Lower respiratory tract symptoms were more common on working days and were predominantly associated with exposure to diluted bleach, degreasing sprays/atomisers and air fresheners. Associations with upper respiratory tract symptoms and PEF were less apparent. Eleven (30%) subjects scored positively for work-related asthma. It is concluded that exposure to certain irritant cleaning products aggravates lower respiratory tract symptoms in female domestic cleaners with asthma or chronic bronchitis.

Characterisation of parapoxviruses isolated from Norwegian semi-domesticated reindeer (Rangifer tarandus tarandus).

BACKGROUND: Two outbreaks of the disease contagious ecthyma were reported in 1999 and 2000 in Norwegian semi-domesticated reindeer (Rangifer tarandus tarandus). Contagious ecthyma is an epidermal disease of sheep and goats worldwide, which is caused by the zoonotic parapoxvirus orf virus. Characterisation of clinical samples from the two outbreaks in semi-domesticated reindeer in Norway by electron microscopy and PCR (B2L) revealed typical parapoxvirus particles and partial gene sequences corresponding to parapoxvirus, respectively. If contagious ecthyma in reindeer is caused by orf virus, the virus may be transferred from sheep and goats, via people, equipment and common use of pastures and corrals, to reindeer. Another possibility is that contagious ecthyma in reindeer is caused by a hitherto unclassified member of the parapoxvirus genus that circulates among reindeer herds and remains endemic in Norway. RESULTS: Genomic comparisons of one standard orf strain (orf NZ2) and the reindeer isolates, employing restriction fragment length polymorphism (RFLP) and random amplified polymorphic DNA (RAPD) analysis, demonstrated high similarity between the reindeer viruses and known orf virus strains. Partial DNA sequences of two different viral genes were determined for the different isolates and compared with corresponding parapoxvirus genebank sequences. The comparison/alignment and construction of phylogenetic trees also point to an affiliation of the reindeer viruses to the species orf virus. CONCLUSION: The results of this work imply that the parapoxvirus causing contagious ecthyma in Norwegian semi-domesticated reindeer belongs to the species orf virus and that the orf virus crosses the host species barrier from sheep and goat to semi-domesticated reindeer.

Agricultural, domestic and handicraft folk uses of plants in the Tyrrhenian sector of Basilicata (Italy).

BACKGROUND: Research was carried out into agricultural and domestic-handicraft uses in folk traditions in the Tyrrhenian sector of the Basilicata region (southern Italy), as it is typically representative of ethnobotanical applications in the Mediterranean area. From the point of view of furnishing a botanical support for the study of local "material culture" data was collected through field interviews of 49 informants, most of whom were farmers. RESULTS: The taxa cited are 60, belonging to 32 botanical families, of which 18 are employed for agricultural uses and 51 for domestic-handicraft folk uses. Data show a diffuse use of plants for many purposes, both in agricultural (present uses 14%; past uses 1%) and for domestic-handicraft use (present uses 40%; past uses 45%); most of the latter are now in decline. CONCLUSION: 60 data look uncommon or typical of the places studied. Some domestic-handicraft folk uses are typical of southern Italy (e.g. the use of Ampelodesmos mauritanicus for making ties, ropes, torches, baskets or that of Acer neapolitanum for several uses). Other uses (e.g. that of Inula viscosa and Calamintha nepeta for peculiar brooms, and of Origanum heracleoticum for dyeing wool red) are previously unpublished.

The social construction of violence: the case of sexual and domestic violence.

What counts as "violence" is socially constructed, has varied over time, and reflects power relationships. Informed by social constructionism, we illustrate these points using as examples sexual violence and domestic violence. We review changes in how society and social scientists have defined and understood these topics during the last 30 years. We then discuss 3 areas of continuing controversy: who should decide if sexual or domestic violence has occurred, what to count as sexual and domestic violence, and the role of gender in defining sexual and domestic violence.

Protein malnutrition in the domestic fowl induces alterations in adrenocortical cell adrenocorticotropin receptors.

Our previous work suggests that persistent protein malnutrition in immature domestic fowl (Gallus gallus domesticus) alters ACTH-adrenocortical cell interaction, possibly including ACTH receptors. To investigate this possibility, we measured some ACTH receptor parameters in isolated adrenocortical cells from normal and dietary protein-restricted domestic fowl. White Leghorn cockerels (2 weeks old) were fed isocaloric semipurified diets containing either 8% [low (L)] or 20% [normal (N)] soy protein for 4 weeks ad libitum. Cockerels were quickly killed by decapitation and exsanguination, and adrenal glands were removed and prepared for cell isolation. Highly enriched (greater than 80% pure) adrenocortical cells (collagenase isolated, followed by separation on a Percoll continuous density gradient) were evaluated for ACTH receptors using pharmacological and radioligand approaches. In a pharmacological approach, we measured the influence of the complete, competitive antagonist, human (h) ACTH-(7-38) on hACTH-(7-39)-induced corticosterone production by adrenocortical cells from L and N cockerels. Inhibitor constants of hACTH-(7-38), calculated from Schild plots, were 3.16 X 10(-7) and 9.82 X 10(-7) M for L and N cockerel cells, respectively, thus suggesting differences in ACTH receptor function between the two treatment groups. To characterize ACTH receptors directly, we measured the binding of a monoiodinated ACTH analog [125I-Tyr23]hACTH-(1-39) to domestic fowl adrenocortical cells. Binding was linear with cell concentration, highly specific (only ACTH peptides caused significant displacement), rapid (maximal binding by 1 h), reversible (half-time of dissociation, approximately 40 min), and saturable. Curvilinear Scatchard plots were obtained, and vectorial analysis resolved both high and low affinity sites. The concentrations (femtomoles per 50 micrograms DNA) and dissociation constants (Kd) of both classes of sites were different between N and L bird cells. Values of these receptor parameters for N and L cockerel cells were, respectively, as follows: concentrations of low affinity sites, 7.45 and 11.60; concentrations of high affinity sites, 3.16 and 5.50; Kd of low affinity sites, 2.05 X 10(-8) and 2.58 X 10(-9) M; Kd of high affinity sites, 1.01 X 10(-9) and 1.27 X 10(-10) M. Thus, the overall binding capacity of L bird cells was 65% greater than that of N bird cells. In addition, the overall affinity (1/Kd) of sites of L bird cells was 9 times that of sites of N bird cells. These data indicate that persistent protein malnutrition in the domestic fowl increased both the number and affinity of adrenocortical cell ACTH receptors.

The postnatal development of neocortical neurons and glial cells in the Göttingen minipig and the domestic pig brain.

The first mathematically unbiased estimates of neocortical cell numbers are presented from the developing pig brain, including a full description of tissue processing and optimal sampling for application of the stereological optical fractionator method in this species. The postnatal development of neocortical neurons and glial cells from the experimental Göttingen minipig was compared with the postnatal development of neocortical neurons in the domestic pig. A significant postnatal development was observed in the Göttingen minipig brain for both neuronal (28%; P=0.01) and glial cells (87%; P<0.01). A corresponding postnatal development of neurons was not detected in the domestic pig brain. The reason for this strain difference is not known. The mean total number of neocortical neurons is 324 million in the adult Göttingen minipig compared with 432 million in the domestic pig. The glial-to-neuron cell ratio is around 2.2 in the adult Göttingen minipig. Based on these results, the domestic pig seems to be a more suitable model for evaluating the effects of developmental insults on human brain growth and neuronal development than the Göttingen minipig.

Mutations that cause amino acid substitutions at the invariant positions in homeodomain of OSH3 KNOX protein suggest artificial selection during rice domestication.

KNOX homeodomain (HD) proteins encoded by KNOTTED1-like homeobox genes (KNOX genes) are considered to work as important regulators for plant developmental and morphogenetic events. We found that OSH3, one of the KNOX genes isolated from a cultivar of Oryza sativa (Nipponbare), encodes a novel HD, which has two amino acid substitutions at invariant positions. Sequence analysis of OSH3 from various domesticated and wild species of rice has revealed that these substitutions are distributed only in Japonica and Javanica type of O. sativa, two groups of domesticated rice in Asia. Surprisingly, nucleotide sequences in the first intron are almost conserved in the rice strains that have the substitutions at the invariant amino acids. Overexpression studies revealed that these invariant amino acids are critical for the function of OSH3 in vivo. The facts that these substitutions occurred specifically at the functionally important amino acids and the sequences are conserved in intron where neutral mutations accumulate suggest the substitutions at the invariant positions of OSH3 have been fixed by artificial selections during domestication. Based on these observations, we hypothesize that OSH3 is responsible for one of the traits that are selectively introduced during the domestication of most of Japonica and a part of Javanica type of rice.

Physicians' response to victims of domestic violence: toward a model of care.

Even though current domestic violence guidelines, such as those published by the AMA in 1992, attempt to relieve physicians of the "full burden of intervention," they continue to call upon physicians to play a large role in identifying, intervening in, and following up on case of partner abuse. In this paper, we define a limited domestic violence role for physicians which furthers the direction recommended by the AMA and which complements exemplary programs. We propose simplifying and limiting physicians' tasks to Asking patients about abuse; providing Validating messages, acknowledging that battering is wrong and confirming patient worth; Documenting presenting signs, symptoms, and disclosures; and Referring victims to domestic violence specialists (AVDR). By drawing on the literature and our own experience, we show how focusing the physician's role on these four taks is consistent with exemplary programs and expands on ideas put forth by experts for addressing domestic violence in health care settings; reduces barriers for physician interventions with victims; offers a realistic approach for physicians, reducing unrealistic educational demands; and complements managed care trends in contemporary health care.

Same-sex domestic partnerships and lower-risk behaviors for STDs, including HIV infection.

To determine the association between domestic partnership status and risk behaviors for sexually transmitted diseases, including HIV infection, we analyzed data from a population-based interviewer-administered telephone survey of 2,881 gay men in San Francisco, Los Angeles, New York and Chicago conducted in November 1996 to February 1998. Men in domestic partnerships had a statistically significantly lower prevalence of multiple partnerships, "one-night stands," and unprotected anal intercourse with a non-primary partner than either men with steady partners not identified as domestic partners or men without a steady partner. These findings were independent of age. Men in domestic partnerships had decreased risk behaviors for sexually transmitted diseases, including HIV infection, suggesting but not proving, that conferring legal status to same-sex unions might decrease sexual risk behavior.

Measuring the lifetime experience of domestic violence: application of the life history calendar method.

In the absence of a "gold standard," research on domestic violence relies primarily on self-report, the quality of which is known to decline as the length of the recall period increases. Eliciting valid and reliable self-report data is crucial to the development of prevention and intervention policies and services. Nevertheless, existing measures typically do not incorporate devices to facilitate respondents' recall of the lifetime experience of domestic violence. This article describes the application of the Life History Calendar (LHC) method (Freedman, Thornton, Camburn, Alwin, & Young-DeMarco, 1988) to increase a respondent's recall of domestic violence victimization over the lifecourse. The LHC method elicits memorable information of a personal nature (e.g., children's birth dates) and uses this information to facilitate the recall of less memorable events. A recent field test of this LHC measure indicates its utility in assessing domestic violence victimization, which takes place in a complex sequence of episodes and often involves multiple perpetrators over the lifecourse.

Presence of nonylphenol ethoxylate surfactants in a watershed in central Mexico and removal from domestic sewage in a treatment wetland.

The Texcoco River in central Mexico is polluted with domestic wastewater as a result of discharges of untreated or inadequately treated sewage. Since nonylphenol ethoxylate (NPEO) surfactants and their intermediate degradation products such as nonylphenol (NP) and NP mono- and diethoxylate (NP1EO, NP2EO) have been found in domestic wastewater and in surface waters near wastewater discharges in industrialized countries, the Texcoco River was sampled to determine whether these compounds were present. The results indicated that NPEOs were present at very high concentrations (> 100 microg/L) in the lower reaches of the Texcoco River, but unlike rivers in industrialized countries, relatively low concentrations of intermediate degradation products, including NP1EO, NP2EO, and NP, were present. The presence and fate of NPEOs compounds in wastewater treatment plants have been studied only in conventional treatment systems in industrialized countries. In this study, the fate of these compounds was studied in a pilot-scale treatment wetland constructed in the small community of Santa Maria Nativitas in the Texcoco River watershed. The treatment wetland removed > 75% of NPEOs from the domestic wastewater, but the greatest proportion of removal occurred in parts of the treatment wetland where sedimentation existed. This is the first report of NPEO compounds in the water resources of a developing country. These data indicate that construction of low-cost and technologically simple treatment wetlands may be one solution to reducing the impacts of contaminants from domestic sewage in developing countries, such as Mexico.

Individual and contextual determinants of domestic violence in North India.

OBJECTIVES: We examined individual- and community-level influences on domestic violence in Uttar Pradesh, North India. METHODS: Multilevel modeling was used to explore domestic violence outcomes among a sample of 4520 married men. RESULTS: Recent physical and sexual domestic violence was associated with the individual-level variables of childlessness, economic pressure, and intergenerational transmission of violence. A community environment of violent crime was associated with elevated risks of both physical and sexual violence. Community-level norms concerning wife beating were significantly related only to physical violence. CONCLUSIONS: Important similarities as well as differences were evident in risk factors for physical and sexual domestic violence. Higher socioeconomic status was found to be protective against physical but not sexual violence. Our results provide additional support for the importance of contextual factors in shaping women's risks of physical and sexual violence.

Recipient preparation and mixed germ cell isolation for spermatogonial stem cell transplantation in domestic cats.

The loss of genetic diversity poses a serious threat to the conservation of endangered species, including wild felids. We are attempting to develop spermatogonial stem cell transplantation in the cat as a tool to preserve and propagate male germ-plasm from genetically valuable animals, be they threatened wild species or lines of cats used as models for inherited diseases. In this study, we investigated the use of local external beam radiation treatment to deplete the endogenous germ cells of male domestic cats, a step necessary to prepare them for use as recipients for transplantation. Testes of 5-month-old domestic cats were irradiated with a fractionated dose of 3 Gy per fraction for 3 consecutive days. These cats were castrated at 2, 4, 8, 16, and 32 weeks posttreatment, and progress of spermatogenesis was evaluated histologically and compared against age-matched controls. Even at the latest time points, less than 10% of tubules contained germ cells at any stage of meiosis, showing the efficacy of this protocol. In addition, male germ cells were isolated from the testes of domestic cats using a 2-step enzymatic dissociation to establish a protocol for the preparation of donor cells. The presence and viability of spermatogonia within this population were demonstrated by successful transplantation into, and colonization of, mouse seminiferous tubules. The success of these protocols provides a foundation to perform spermatogonial stem cell transplantation in the domestic cat.

Experimental infection of Mouflon-domestic sheep hybrids with caprine arthritis-encephalitis virus.

OBJECTIVE: To determine whether monocyte-derived macrophages from Mouflon-domestic sheep hybrids (Ovis musimon X Ovis spp) were susceptible to productive infection with caprine arthritis-encephalitis virus (CAEV) in vitro and whether experimental inoculation of Mouflon-domestic sheep hybrids with a molecularly cloned CAEV would result in persistent infection. ANIMALS: 5 Mouflon hybrids. PROCEDURE: Macrophage monolayers were inoculated with virus in vitro. Three animals were inoculated with virus intratracheally. RESULTS: Productive replication of CAEV was demonstrated in monocyte-derived macrophages following in vitro and in vivo inoculation. Titer of infectious cytopathic CAEV produced by macrophages from the Mouflon hybrids was similar to titers produced by macrophages from an infected goat or by synovial membrane cells. Isolation of virus from monocyte-derived macrophages and use of a semiquantitative polymerase chain reaction assay to amplify a portion of the viral genome demonstrated persistent virus replication in all 3 inoculated animals. Two weeks after inoculation of sheep, approximately 1 of 5,000 monocytes was harboring the virus. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicate that Mouflon-domestic sheep hybrids are susceptible to infection with isolates of CAEV that cause infection in domestic small ruminants.

Nurses' understanding of domestic violence.

Domestic violence is considered to be an important health care issue world wide. In order to provide appropriate support and treatment to women who have been abused, it is essential that nurses understand and recognise domestic violence. This study aimed to explore nurses' understanding of domestic violence issues utilising a grounded theory approach. A total of 41 emergency nurses was interviewed in selected Australian and Japanese emergency departments. Analysis of data identified six groups of nurse perceivers of domestic violence: nave perceivers, inexperienced perceivers, compassionate perceivers, proactive perceivers, acting perceivers and reluctant perceivers. Findings indicate that the provision of ongoing education and instigation of policy and protocol enable nurses to respond in a structured manner when they encounter women who have been abused. As a result, nurses can contribute to the amelioration of violence in society and enhance the wellbeing of these women.

Comparison of pulmonary defense mechanisms in Rocky Mountain bighorn (Ovis canadensis canadensis) and domestic sheep.

Alveolar macrophages were obtained from Rocky Mountain bighorn sheep (Ovis canadensis canadensis) and domestic sheep for the purpose of comparing pulmonary host defense mechanisms in the two species. Specific variables studied included (1) characterization of the cell types present in the lung, (2) alveolar macrophage phagocytic and bactericidal functions, (3) measurement of protein levels in lavage fluid, and (4) measurement of cortisol levels in lavage fluid. While phagocytic cell populations were similar between bighorn and domestic sheep, a significantly higher percentage of lymphocytes were present in bighorns than domestics (20% in bighorn versus 6% in domestic sheep). Significant differences were not observed in the phagocytic or bactericidal functions of macrophages between the two species. Significant differences were not observed in either lavage fluid protein levels or in cortisol levels.
