Criminal offences involving firearms in New South Wales, 1995-2011

Despite the recent upward trend in drive-by shootings, the the number of incidents involving a firearm in New South Wales declined by 48% between 1995 and 2011. Aim: To investigate trends over time, spatial patterns, and characteristics of criminal offences involving firearms. Method: This study used data from the NSW Police Force Computerised Operational Policing System and the Australian Bureau of Statistics. Characteristics and spatial patterns of offences involving firearms were described and trends across 1995 to 2011 were analysed using Kendall’s rank-order correlation test. Results: The number of incidents involving a firearm declined (48% between 1995 and 2011). Robbery involving a firearm decreased (51%, 1995-2011) and unlawfully discharge firearm decreased (24%, 1995-2011), although discharge firearm into premises increased (144%, 1995-2011). The rate of shoot with intent incidents per 100,000 population in Sydney was greater than the rest of NSW. The average age of male offenders was 24.2 years for robbery, 26.6 years for murder and attempted murder, 30.9 years for assault, and 36.5 years for harassment involving firearms in 2011. Homicide, assault, abduction and kidnapping, and harassment involving firearms occurred mostly in residences in 2011. Robbery involving firearms occurred mostly in business/commercial premises. The rate of firearm theft was lower in Sydney than the rest of NSW in 2011 (0.8 and 6.4 per 100,000 population, respectively). Firearms were most frequently stolen from residences (79%, 2011). Rifles were the most stolen firearm (66%, 2011). Conclusion: Despite the recent upward trend in drive-by shootings, the long-term trend in criminal offences involving firearms is down

Reporting violence to police: a survey of victims attending domestic violence services

Aim: The aim of the study was to investigate what proportion of domestic violence (DV) victims who seek help from DV services choose not to report the violence to police and to investigate factors and reasons associated with non-reporting.Method: Data was collected by interviewing 300 victims attending DV services. The interview was conducted by telephone and included questions on (a) victim characteristics, (b) characteristics of victims’ most recent incident, and (c) victims’ reasons for not reporting to police. Descriptive and bivariate analyses were undertaken to determine characteristics associated with the decision to report a domestic violence incident to police.Results: Approximately half (51.8%) of victims reported their most recent incident to the police. Victims were more likely to report if they had an AVO against the offender, if their property had been damaged, if they were physically injured, if the abuse was physical or sexual, if they felt their children were at risk or if they had reported previous DV incidents. Victims were less likely to report if they were pregnant or experienced more than 5 previous incidents of abuse. The top three reasons for not reporting to police were fear of revenge/further violence (13.9%), embarrassment/shame (11.8%), or the incident was too trivial/unimportant (11.8%). The primary barrier to reporting, according to those interviewed, is that police either do not understand or are not proactive in handling DV (17.1%).Conclusion: Half of victims reported DV to the police, leaving the remainder without official legal intervention and professional support

Can Carbon Sinks be Operational? An RFF Workshop Summary

An RFF Workshop brought together experts from around the world to assess the feasibility of using biological sinks to sequester carbon as part of a global atmospheric mitigation effort. The chapters of this proceeding are a result of that effort. Although the intent of the workshop was not to generate a consensus, a number of studies suggest that sinks could be a relatively inexpensive and effective carbon management tool. The chapters cover a variety of aspects and topics related to the monitoring and measurement of carbon in biological systems. They tend to support the view the carbon sequestration using biological systems is technically feasible with relatively good precision and at relatively low cost. Thus carbon sinks can be operational.carbon, sinks, global warming, sequestration, forests

Endothelial cell processing and alternatively spliced transcripts of factor VIII: potential implications for coagulation cascades and pulmonary hypertension.

BACKGROUND: Coagulation factor VIII (FVIII) deficiency leads to haemophilia A. Conversely, elevated plasma levels are a strong predictor of recurrent venous thromboemboli and pulmonary hypertension phenotypes in which in situ thromboses are implicated. Extrahepatic sources of plasma FVIII are implicated, but have remained elusive. METHODOLOGY/PRINCIPAL FINDINGS: Immunohistochemistry of normal human lung tissue, and confocal microscopy, flow cytometry, and ELISA quantification of conditioned media from normal primary endothelial cells were used to examine endothelial expression of FVIII and coexpression with von Willebrand Factor (vWF), which protects secreted FVIII heavy chain from rapid proteloysis. FVIII transcripts predicted from database mining were identified by RT-PCR and sequencing. FVIII mAb-reactive material was demonstrated in CD31+ endothelial cells in normal human lung tissue, and in primary pulmonary artery, pulmonary microvascular, and dermal microvascular endothelial cells. In pulmonary endothelial cells, this protein occasionally colocalized with vWF, centered on Weibel Palade bodies. Pulmonary artery and pulmonary microvascular endothelial cells secreted low levels of FVIII and vWF to conditioned media, and demonstrated cell surface expression of FVIII and vWF Ab-reacting proteins compared to an isotype control. Four endothelial splice isoforms were identified. Two utilize transcription start sites in alternate 5 exons within the int22h-1 repeat responsible for intron 22 inversions in 40% of severe haemophiliacs. A reciprocal relationship between the presence of short isoforms and full-length FVIII transcript suggested potential splice-switching mechanisms. CONCLUSIONS/SIGNIFICANCE: The pulmonary endothelium is confirmed as a site of FVIII secretion, with evidence of synthesis, cell surface expression, and coexpression with vWF. There is complex alternate transcription initiation from the FVIII gene. These findings provide a framework for future research on the regulation and perturbation of FVIII synthesis, and of potential relevance to haemophilia, thromboses, and pulmonary hypertensive states

Age structure and disturbance legacy of North American forests

Most forests of the world are recovering from a past disturbance. It is well known that forest disturbances profoundly affect carbon stocks and fluxes in forest ecosystems, yet it has been a great challenge to assess disturbance impacts in estimates of forest carbon budgets. Net sequestration or loss of CO<sub>2</sub> by forests after disturbance follows a predictable pattern with forest recovery. Forest age, which is related to time since disturbance, is a useful surrogate variable for analyses of the impact of disturbance on forest carbon. In this study, we compiled the first continental forest age map of North America by combining forest inventory data, historical fire data, optical satellite data and the dataset from NASA's Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) project. A companion map of the standard deviations for age estimates was developed for quantifying uncertainty. We discuss the significance of the disturbance legacy from the past, as represented by current forest age structure in different regions of the US and Canada, by analyzing the causes of disturbances from land management and nature over centuries and at various scales. We also show how such information can be used with inventory data for analyzing carbon management opportunities. By combining geographic information about forest age with estimated C dynamics by forest type, it is possible to conduct a simple but powerful analysis of the net CO<sub>2</sub> uptake by forests, and the potential for increasing (or decreasing) this rate as a result of direct human intervention in the disturbance/age status. Finally, we describe how the forest age data can be used in large-scale carbon modeling, both for land-based biogeochemistry models and atmosphere-based inversion models, in order to improve the spatial accuracy of carbon cycle simulations

Trends in North American net primary productivity derived from satellite observations, 1982-1998

Net primary productivity (NPP) in North America was computed for the years 1982–1998 using the Carnegie‐Ames‐Stanford approach (CASA) carbon cycle model. CASA was driven by a new, corrected satellite record of the normalized difference vegetation index at 8‐km spatial resolution. Regional trends in the 17‐year NPP record varied substantially across the continent. Croplands and grasslands of the Central Plains and eastern Canadian forests experienced summer increases in NPP. Peak NPP trends in Alaska and western Canada occurred in late spring or early summer, suggesting an earlier onset of the growing season in these regions. Forests and woodlands of the southeastern United States showed NPP increases in spring and fall, also suggesting an increase in the length of the growing season. An analysis of climate variables showed that summer precipitation increased in the Central Plains, indicating that climate changes probably play some role in increasing NPP in this region, though intensive management of agricultural ecosystems has also increased productivity. Similarly, increased summer precipitation possibly increased NPP in eastern Canada, but another possible explanation is forest recovery after insect damage. NPP in the southeastern United States increased in the absence of climate variation. Much of this region consists of aggressively managed forests, with young stand ages and intensive silviculture resulting in increased NPP. The high latitudes of western Canada and Alaska experienced spring warming that could have increased NPP in late spring or early summer

Satellite-derived increases in net primary productivity across North America, 1982-1998

We used a new 17‐year, high spatial resolution satellite record and a carbon cycle model to explore how changing net primary productivity (NPP) contributed to a proposed carbon (C) sink in North America. We found a small but significant increase in NPP, 0.03 Pg C yr^(−2) or 8% over 17 years, that could explain a substantial fraction of the C sink. The largest increases occurred in the central and southeastern United States, eastern Canada, and northwestern North America, and were consistent with NPP trends derived from forest inventories and crop yields. Interannual NPP variability was small, implying that the large interannual variability in the C sink found in previous studies were driven by changes in heterotrophic respiration

Integrating CBT and CFT within a case formulation approach to reduce depression and anxiety in an older adult with a complex mental and physical health history: A single case study

Depression and anxiety are major contributors to growing healthcare costs in the UK, particularly with an increasingly ageing population. However, identification of mental health needs in older adults has been overshadowed by a tendency to focus on physical health issues, despite the established co-morbidity of depression, anxiety and physical health conditions. When older adults seek psychological support, treatment options may vary and may be time limited, either because of protocol guidance or due to the resource constraints of psychology services. Time-limited treatment, common in many adult services, may not best meet the needs of older adults, whose physical, cognitive and emotional needs alter with age. It is, therefore, important to identify treatments that best meet the needs of older adults who seek psychological support, but who may arrive with complex mental and physical health histories. This paper aims to explore how a case formulation-driven approach that draws on the theoretical underpinnings of cognitive behavioural therapy (CBT) and compassion-focused therapy (CFT) can be used to reduce anxiety and depression in an older adult with a complex multi-morbid mental and physical health history. This study employs a single-case (A–B) experimental design [assessment (A), CBT and CFT intervention (B)] over 28 sessions. Results suggest the greatest reductions in depression and anxiety (as measured using PHQ-9 and GAD-7) occurred during the CFT phase of the intervention, although scores failed to drop below subclinical levels in any phase of the intervention. This case highlights the value of incorporating CFT with CBT in case formulation-driven interventions

Physiological and perceptual responses to training and competition in elite female netball players

Few studies have reported the physical demands of, and physiological responses to, training and competition in international netball players. This thesis set out to investigate this in female players via a series of studies. Study one characterised the playing demands of international match-play, and the physiological and perceptual responses to an international netball tournament. Mid-court performed at a higher Player LoadTM (mean difference ± standard deviation: 85.7% ± 49.6%), and internal intensity (mean heart rate: 3.7% ± 3.8%) than goal-based positions. Neuromuscular performance decreased after a single match (jump height: 4.0% ± 2.5%) whilst markers of muscle damage, soreness and perceived fatigue accumulated across the tournament. Study two characterised the physiological and perceptual responses to a regularly performed netball-training session. Neuromuscular performance was enhanced immediately post-exercise (Cohen’s d effect size, percent change: peak power output: 0.47, 5%), returned to baseline two hours post, and was reduced 24 h post-training (peak power output: 0.27, 3%; jump height: 0.39, 6%). Study three investigated the effect of training-session order. Performing netball prior to strength training resulted in enhanced neuromuscular performance two hours post-training (peak power output: 1.2, 5%; jump height: 1.2, 9%; peak velocity: 1.0, 3%), whilst strength followed by netball reduced neuromuscular performance at 20 h post (peak power output: 1.1, 4%; jump height: 1.4, 10%; peak velocity: 1.4, 4%). This thesis provides a detailed investigation in to the responses to netball training and competition, as well as the impact of training-session order on neuromuscular, perceptual and endocrine responses over 20 h. Training should be individualised to condition players for the positional-specific external and internal demands of international match-play. To optimise training performance, two hours post-training could be a more favourable time to perform explosive training than the following day, whilst technical netball training should precede strength training when both sessions are performed within the same training day
