Preventing family violence: Investigating the theoretical orientations and techniques of New Zealand migrant communities

While New Zealand legal and cultural sanctions against family violence are strong, representative surveys suggest that approximately 1 in 3 women has experienced physical violence from a partner in her lifetime, and every year approximately 14 women, 6 men, and 10 children die in New Zealand due to family violence. Evidence shows that family violence impacts members of all ethnic and cultural backgrounds, and migrant victims may suffer in silence more often than others due to social isolation and language or cultural barriers. Limited research is available on how the Duluth model, a popular feminist theoretical understanding of violence, is relevant to the experiences of migrants. This theory posits that patriarchal culture and men’s psychological desire for power and control facilitate violence toward women. As government agencies and community organizations act to prevent family violence, research is needed on how this model is relevant to understandings of violence that are prevalent in migrant communities. We must also increase our limited knowledge about how prevention efforts can be more inclusive of these groups. Two qualitative studies were conducted to explore these questions. In Study 1, I investigated the theoretical relevance of the Duluth model to New Zealand migrant communities, collecting data in partnership with two community groups that have organized informal family violence prevention initiatives. I conducted semi-structured interviews with community leaders and focus groups with community members. The findings suggest that participants viewed violence as caused either by desire for control (compatible with the Duluth model) or anger (incompatible). Participants articulated the need to balance rights (compatible) with responsibilities in interdependent, role-based family relationships (incompatible). Based on these findings, I suggest a two-pronged approach, where pre-violence prevention targets potential perpetrators by focusing on the responsibility to treat others well and post-violence intervention emphasizes victims’ rights. In Study 2, I analyzed the processes and strategies that community groups use to prevent violence. Data collection occurred during the same interviews and focus groups as the previous study, using a different set of questions and stimuli. My analysis indicated that participants used prevention strategies that validated and reduced ambivalence about the harmful nature of non-physical violence. Particularly in religious communities, leaders invoked aspirational cultural ideals that were intended to motivate positive behaviors and encourage healthy relationships. At the community level, participants identified opportunities to improve multilevel communication in order to enhance the benefits of cultural community engagement. I suggest that in addition to thoroughly evaluating these approaches for efficacy in migrant communities, we should consider how these approaches might be beneficially employed in mainstream initiatives. These findings suggest that nuanced understandings of family interdependence and responsibility can increase the relevance of family violence prevention campaigns to migrant communities. The findings and recommendations were synthesized into a framework for migrant community groups and their government partners. While research is needed to examine the effects of these strategies, they may increase the applicability of prevention initiatives to migrant communities and may also be explored as appropriate strategies for mainstream prevention campaigns

A 43-GHz Survey in the ELAIS N2 Area

We describe a survey in the ELAIS N2 region with the VLA at 43.4 GHz, carried out with 1627 independent snapshot observations in D-configuration and covering about 0.5 square degrees. One certain source is detected, a previously-catalogued flat-spectrum QSO at z=2.2. A few (<5) other sources may be present at about the 3sigma level, as determined from positions of source-like deflections coinciding with blue stellar objects, or with sources from lower-frequency surveys. Independently we show how all the source-like detections identified in the data can be used with a maximum-likelihood technique to constrain the 43-GHz source counts at a level of ~7 mJy. Previous estimates of the counts at 43 GHz, based on lower-frequency counts and spectral measurements, are consistent with these constraints, although the present results are suggestive of somewhat higher surface densities at the 7 mJy level. They do not provide direct evidence of intrusion of a previously unknown source population, although the several candidate sources need examination before such a population can be ruled out.Comment: 13 pages, 11 figures, 1 table; accepted for publication in Mon.

Interventions to reduce suicides at suicide hotspots: a systematic review

BACKGROUND: 'Suicide hotspots' include tall structures (for example, bridges and cliffs), railway tracks, and isolated locations (for example, rural car parks) which offer direct means for suicide or seclusion that prevents intervention. METHODS: We searched Medline for studies that could inform the following question: 'What interventions are available to reduce suicides at hotspots, and are they effective?' RESULTS: There are four main approaches: (a) restricting access to means (through installation of physical barriers); (b) encouraging help-seeking (by placement of signs and telephones); (c) increasing the likelihood of intervention by a third party (through surveillance and staff training); and (d) encouraging responsible media reporting of suicide (through guidelines for journalists). There is relatively strong evidence that reducing access to means can avert suicides at hotspots without substitution effects. The evidence is weaker for the other approaches, although they show promise. CONCLUSIONS: More well-designed intervention studies are needed to strengthen this evidence base.Australian Government Department of Health and AgeingUK National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care for the Southwest Peninsul

The Impact of Different Classification Criteria Sets on the Estimated Prevalence and Associated Risk Factors of Diastolic Dysfunction in Rheumatoid Arthritis

This study compared the estimated prevalence and potential determinants of left ventricular (LV) diastolic dysfunction upon applying different classification criteria in rheumatoid arthritis (RA). LV diastolic function was assessed echocardiographically by pulsed Doppler (E/A), tissue Doppler (E/e′, lateral and septal e′), and left atrial volume index in 176 RA patients. Relationships of traditional cardiovascular risk factors and RA characteristics with LV diastolic function and dysfunction according to previous and current criteria were determined in multivariate regression models. Waist-hip ratio was associated with E/A (standardised β (SE) = -0.28±0.09, p=0.0002) and lateral e′ (standardised β (SE) = 0.26±0.09, p=0.01); low diastolic blood pressure was related to E/e′ (standardised β (SE) = -0.16±0.08, p=0.04). Diastolic dysfunction prevalence differed upon applying previous (59%) compared to current (22%) criteria (p<0.0001). One SD increase in waist-hip ratio was associated with diastolic dysfunction when applying current criteria (OR = 2.61 (95% CI = 1.51–4.52), p=0.0006), whereas one SD increase in diastolic blood pressure was inversely related to diastolic dysfunction upon using previous criteria (OR = 0.57 (95% CI = 0.40–0.81), p=0.002). In conclusion, application of current and previous diastolic dysfunction criteria markedly alters the prevalence and risk factors associated with diastolic dysfunction in RA

ALE Meta-Analysis Workflows Via the Brainmap Database: Progress Towards A Probabilistic Functional Brain Atlas

With the ever-increasing number of studies in human functional brain mapping, an abundance of data has been generated that is ready to be synthesized and modeled on a large scale. The BrainMap database archives peak coordinates from published neuroimaging studies, along with the corresponding metadata that summarize the experimental design. BrainMap was designed to facilitate quantitative meta-analysis of neuroimaging results reported in the literature and supports the use of the activation likelihood estimation (ALE) method. In this paper, we present a discussion of the potential analyses that are possible using the BrainMap database and coordinate-based ALE meta-analyses, along with some examples of how these tools can be applied to create a probabilistic atlas and ontological system of describing function–structure correspondences

Astromineralogy of the 13 μm Feature in the Spectra of Oxygen-rich Asymptotic Giant Branch Stars. I. Corundum and Spinel

http://iopscience.iop.org/0004-637X/640/2/971/pdf/0004-637X_640_2_971.pdfAsymptotic giant branch (AGB) stars have several interesting infrared spectral features. Approximately half the oxygen-rich AGB stars to be investigated spectroscopically exhibit a feature at ~13 μm. The carrier of this feature has not yet been unequivocally identified but has been attributed to various dust species, including corundum (α-Al2O 3), spinel (MgAl2O4), and silica (SiO 2). In order to constrain the carrier of the 13 μm feature, we have used the one-dimensional radiative transfer code DUSTY to model the effects of composition and optical depth on the shape and strength of the emerging 13 μm feature from corundum and spinel grains. We have modeled various corundum, spinel, corundum-silicate, and spinel-silicate mixtures in dust shells surrounding O-rich AGB stars. These models demonstrate that (1) if corundum is present in these circumstellar dust shells, even at very low relative abundances, a ~13 μm feature should be observed; (2) corundum's weak ~21 μm feature will not be observed, even if it is responsible for the ~13 μm feature; (3) even at low relative abundances, spinel exhibits a feature at 16.8 μm that is not found in observations; and (4) the grains must be spherical. Other grain shapes (spheroids, ellipsoids, and hollow spheres) shift the features to longer wavelengths for both spinel and corundum. Our models show that spinel is unlikely to be the carrier of the 13 μm feature. The case for corundum as the carrier is strengthened but not yet proven.This work is supported in part by NASA grant APRA04-0000-0041

A Critical Review of the \u3csup\u3e15\u3c/sup\u3eN\u3csub\u3e2\u3c/sub\u3e Tracer Method to Measure Diazotrophic Production in Pelagic Ecosystems

Dinitrogen (N2) fixation is an important source of biologically reactive nitrogen (N) to the global ocean. The magnitude of this flux, however, remains uncertain, in part because N2 fixation rates have been estimated following divergent protocols and because associated levels of uncertainty are seldom reported—confounding comparison and extrapolation of rate measurements. A growing number of reports of relatively low but potentially significant rates of N2 fixation in regions such as oxygen minimum zones, the mesopelagic water column of the tropical and subtropical oceans, and polar waters further highlights the need for standardized methodological protocols for measurements of N2 fixation rates and for calculations of detection limits and propagated error terms. To this end, we examine current protocols of the 15N2 tracer method used for estimating diazotrophic rates, present results of experiments testing the validity of specific practices, and describe established metrics for reporting detection limits. We put forth a set of recommendations for best practices to estimate N2 fixation rates using 15N2 tracer, with the goal of fostering transparency in reporting sources of uncertainty in estimates, and to render N2 fixation rate estimates intercomparable among studies

Structured Observations Reveal Slow HIV-1 CTL Escape

The existence of viral variants that escape from the selection pressures imposed by cytotox- ic T-lymphocytes (CTLs) in HIV-1 infection is well documented, but it is unclear when they arise, with reported measures of the time to escape in individuals ranging from days to years. A study of participants enrolled in the SPARTAC (Short Pulse Anti-Retroviral Thera- py at HIV Seroconversion) clinical trial allowed direct observation of the evolution of CTL es- cape variants in 125 adults with primary HIV-1 infection observed for up to three years. Patient HLA-type, longitudinal CD8+ T-cell responses measured by IFN- γ ELISpot and lon- gitudinal HIV-1 gag , pol , and nef sequence data were used to study the timing and preva- lence of CTL escape in the participants whilst untreated. Results showed that sequence variation within CTL epitopes at the first time point (within six months of the estimated date of seroconversion) was consistent with most mutations being transmitted in the infecting viral strain rather than with escape arising within the first few weeks of infection. Escape arose throughout the first three years of infection, but slowly and steadily. Approximately one third of patients did not drive any new escape in an HLA-restricted epitope in just under two years. Patients driving several escape mutations during these two years were rare and the median and modal numbers of new escape events in each patient were one and zero re- spectively. Survival analysis of time to escape found that possession of a protective HLA type significantly reduced time to first escape in a patient (p = 0.01), and epitopes escaped faster in the face of a measurable CD8+ ELISpot response (p = 0.001). However, even in an HLA matched host who mounted a measurable, specific, CD8+ response the average time before the targeted epitope evolved an escape mutation was longer than two year
