Predicting avian distributions to evaluate spatiotemporal overlap with locust control operations in eastern Australia.

Locusts and grasshoppers cause considerable economic damage to agriculture worldwide. The Australian Plague Locust Commission uses multiple pesticides to control locusts in eastern Australia. Avian exposure to agricultural pesticides is of conservation concern, especially in the case of rare and threatened species. The aim of this study was to evaluate the probability of pesticide exposure of native avian species during operational locust control based on knowledge of species occurrence in areas and times of application. Using presence-absence data provided by the Birds Australia Atlas for 1998 to 2002, we developed a series of generalized linear models to predict avian occurrences on a monthly basis in 0.5 degrees grid cells for 280 species over 2 million km2 in eastern Australia. We constructed species-specific models relating occupancy patterns to survey date and location, rainfall, and derived habitat preference. Model complexity depended on the number of observations available. Model output was the probability of occurrence for each species at times and locations of past locust control operations within the 5-year study period. Given the high spatiotemporal variability of locust control events, the variability in predicted bird species presence was high, with 108 of the total 280 species being included at least once in the top 20 predicted species for individual space-time events. The models were evaluated using field surveys collected between 2000 and 2005, at sites with and without locust outbreaks. Model strength varied among species. Some species were under- or over-predicted as times and locations of interest typically did not correspond to those in the prediction data set and certain species were likely attracted to locusts as a food source. Field surveys demonstrated the utility of the spatially explicit species lists derived from the models but also identified the presence of a number of previously unanticipated species. These results also emphasize the need for special consideration of rare and threatened species that are poorly predicted by presence-absence models. This modeling exercise was a useful a priori approach in species risk assessments to identify species present at times and locations of locust control applications, and to discover gaps in our knowledge and need for further focused data collection.

Influence of birth cohort on age of onset cluster analysis in bipolar I disorder

Two common approaches to identify subgroups of patients with bipolar disorder are clustering methodology (mixture analysis) based on the age of onset, and a birth cohort analysis. This study investigates if a birth cohort effect will influence the results of clustering on the age of onset, using a large, international database.

Interventions to improve medication adherence in adult kidney transplant recipients: a systematic review.

In kidney transplantation, adherence to immunosuppressive therapy is paramount for long-term graft survival. This systematic review aimed to assess the effectiveness of interventions to improve medication adherence in adult kidney transplantation.

Workplace spirituality and organizational commitment influence on job performance among academic staff

This study examines the relationships between spirituality in the workplace, organizational commitment and job performance measured in terms of key performance indicators (KPIs) based on a sample of 376 academic staff at Universiti Sains Malaysia (USM). The methods used in the study are factor analysis and multiple regression analysis. Three factors are found to explain organizational commitment: affective commitment, continuance commitment and normative commitment. Affective and normative commitments are positively influenced by workplace spirituality, which is explained by three factors: alignment between organizational and individual values; sense of enjoyment at work and contribution to community; and opportunity for inner life. The study also finds that neither high commitment nor workplace spirituality among academic staff necessarily manifest in high KPIs. Instead, other staff background variables appear to have more influence on job performance, such as gender, stream, age and rank.

Social capital and organisational commitment at higher education institutions

This study compares the extent of the influence of non-tangible forms of social capital on organisational commitment at Universiti Sains Malaysia (USM), in Penang, Malaysia and two universities in Sumatra, Indonesia, which are, Universitas Andalas and Padang State University. In this study, Universitas Andalas and Padang State University will be represented by APU. Amongst the academic staff at USM, three social capital factors-collective action and shared values, relational trust and cooperation, and cohesive bonds and connectivity through participation-have a strong positive impact on affective and normative commitments. At APU, only the factor of cohesive bonds and connectivity contributes to affective commitment. Collective action and shared values as well as cohesive bonds and connectivity were shown to have contributed to higher normative commitment. Relational trust and cooperation, which are important indicators of social capital, did not seem to have any impact on the three organisational commitments. At USM, continuance commitment was negatively related to cohesive bonds and was not related to any other predictive variables. At APU, higher collective action and shared values reduced continuance commitment.

Examining the preparation and ongoing support of adults to take their medications as prescribed in kidney transplantation.

RATIONALE, AIMS AND OBJECTIVES: The shortage of kidney donors and benefits of kidney transplantation make graft success imperative. Medication adherence is critical to prevent the risk of graft rejection. This paper examines how adults are prepared and supported by renal transplant co-ordinators and pharmacists to take their medications as prescribed in kidney transplantation. METHODS: Renal transplant co-ordinators and pharmacists of all five hospitals offering adult kidney transplantation in Victoria, Australia, were interviewed between November 2013 and February 2014. All data underwent qualitative descriptive analysis. RESULTS: Nine renal transplant co-ordinators and six pharmacists were interviewed. Although there was no standardized approach to education or other evidence-based strategies to facilitate medication adherence, there were similarities between sites. These similarities included printed information, pre-transplant education sessions, the use of medication lists and medication administration aids, intensive education in hospital and ensuring an adequate supply of medications post-discharge. CONCLUSIONS: Renal transplant co-ordinators and pharmacists recognized the importance of early patient education concerning immunosuppressant medication. However, each site had developed their own way of preparing a patient for kidney transplantation and follow-up in the acute hospital setting based on experience and practice. Other non-educational strategies involving behavioural and emotional aspects were less common. Differences in usual care reinforce the necessity for evidence-based health care for best patient outcomes.

The potential contribution of intermediary organizations for implementation of school mental health

Questions persist regarding implementation of mental health promotion, prevention, and early intervention initiatives in schools. To date, attention has targeted the ‘Whats’ and ‘Hows’ in design and implementation. Ongoing clarification of ‘Who’ the key proponents are working in this space receives less consideration. This paper presents outcomes from a national colloquium involving leaders from organizations committed to school-based mental health practice in Australia. The aim of the colloquium was to introduce the concept of Intermediary Organizations (IOs) examining this for its potential contribution to improved mental health and school improvement. The central challenge for IOs is implementation, that is, assisting in knowledge mobilization connecting research to policy and practice. The colloquium discussion was grounded in an understanding of public value as an organizing principle for improving public sector effectiveness. The participants evaluated the nature, role, and potential contribution of IOs. Three key issues emerged as being central to effective implementation: health promotion and prevention, relational ethics, and evidence-based practice.

Health-care costs over 15 years after bariatric surgery for patients with different baseline glucose status: results from the Swedish Obese Subjects study

BACKGROUND: Bariatric surgery prevents and induces remission of type 2 diabetes in many patients. The effect of preoperative glucose status on long-term health-care costs is unknown. We aimed to assess health-care costs over 15 years for patients with obesity treated conventionally or with bariatric surgery and who had either euglycaemia, prediabetes, or type 2 diabetes before intervention. METHODS: The Swedish Obese Subjects (SOS) study is a prospective study of adults who had bariatric surgery and contemporaneously matched controls who were treated conventionally (age 37-60 years; BMI of ≥34 in men and ≥38 in women) recruited from 25 Swedish surgical departments and 480 primary health-care centres. Exclusion criteria were identical for both study groups, and were previous gastric or bariatric surgery, recent malignancy or myocardial infarction, selected psychiatric disorders, and other contraindicating disorders to bariatric surgery. Conventional treatment ranged from no treatment to lifestyle intervention and behaviour modification. In this study, we retrieved prescription drug costs for the patients in the SOS study via questionnaires and the nationwide Swedish Prescribed Drug Register. We retrieved data for inpatient and outpatient visits from the Swedish National Patient Register. We followed up the sample linked to register data for up to 15 years. We adjusted mean differences for baseline characteristics. Analyses were by intention to treat. The SOS study is registered with ClinicalTrials.gov, number NCT01479452. FINDINGS: Between Sept 1, 1987, and Jan 31, 2001, 2010 adults who had bariatric surgery and 2037 who were treated conventionally were enrolled into the SOS study. In this study, we followed up 4030 patients (2836 who were euglycaemic; 591 who had prediabetes; 603 who had diabetes). Drug costs did not differ between the surgery and conventional treatment groups in the euglycaemic subgroup (surgery US$10,511 vs conventional treatment $10,680; adjusted mean difference -$225 [95% CI -2080 to 1631]; p=0·812), but were lower in the surgery group in the prediabetes ($10,194 vs $13,186; -$3329 [-5722 to -937]; p=0·007) and diabetes ($14,346 vs $19,511; -$5487 [-7925 to -3049]; p<0·0001) subgroups than in the conventional treatment group. Compared with the conventional treatment group, we noted greater inpatient costs in the surgery group for the euglycaemic ($51,225 vs $25,313; $22,931 [19,001-26,861]; p<0·0001), prediabetes ($58,699 vs $32,861; $27,152 [18,736-35,568]; p<0·0001), and diabetes ($61,569 vs $47,569; 18,697 [9992-27,402]; p<0·0001) subgroups. We noted no differences in outpatient costs. Total health-care costs were higher in the surgery group in the euglycaemic ($71,059 vs $45,542; $22,390 [17,358-27,423]; p<0·0001) and prediabetes ($78,151 vs $54,864; $26,292 [16,738-35,845]; p<0·0001) subgroups than in the conventional treatment group, whereas we detected no difference between treatment groups in patients with diabetes ($88,572 vs $79,967; $9081 [-1419 to 19,581]; p=0·090). INTERPRETATION: Total health-care costs were higher for patients with euglycaemia or prediabetes in the surgery group than in the conventional treatment group, but we detected no difference between the surgery and conventional treatment groups for patients with diabetes. Long-term health-care cost results support prioritisation of patients with obesity and type 2 diabetes for bariatric surgery. FUNDING: AFA Försäkring and Swedish Scientific Research Council.
