A local population of velvet-furred rats, Rattus lutreolus velutinus, was studied for 15 months in wet sclerophyll forest in south-eastem Tasmania using mark-recapture techniques. Individuals in the trappable population were readily caught with 90% of captures being recaptures (73 individuals caught 706 times). During winter and the summer breeding season, all individuals had an equal likelihood of recapture, irrespective of sex, age, season or previous capture history. Habitat use was investigated by analysing floristic and structural variation within a 4-ha trapping grid using TWINSPAN. Four heterogeneous habitat groups were defined and population data are compared among these groups. Areas of densest ground cover were preferred by R. 1. velutinus; open areas were avoided. Throughout the study, female rats were captured in the areas with most cover to 50 cm in height; during winter, males were caught in areas of the trapping grid with more sparse ground cover, in lower numbers than females. At the onset of breeding in summer, numerous males were captured in the areas of thickest ground cover occupied by females. These data are discussed in relation to social spacing, habitat utilisation and female choice.

A local population of Tasmanian long-tailed mice, Pseudomys higginsi, occupying an area of wet sclerophyll forest at low density was studied for 13 months using mark-recapture techniques. Individuals in the trappable population were readily recaught (29 individuals caught 183 times). Demographic data are presented for a single age cohort born in 1989 (21 individuals trapped 126 times) and surviving until the end of the trapping programme (April 1990). Habitat use was investigated by comparing data from individuals active within four contiguous areas of forest displaying structural and floristic heterogeneity. Trap-revealed habitat use indicated that P. higginsi was completely absent from areas of thickest ground cover where densities of the sympatric murid, Rams lutreolus velutinus, were highest. Conversely, captures of P. higginsi were highest in areas of boulder scree where captures of R. 1. velutinus were lower than expected. Relative numbers of individuals active in each macrohabitat group are examined and a role for interspecific competition between these rodent species is inferred.

AbstractThe paper compares and contrasts internal migration measured by healthcard-based administrative data with census figures. This is useful because the collection of population data, its processing, and its dissemination by statistical agencies is becoming more reliant on administrative data. Statistical agencies already use healthcard data to make migration estimates and are increasingly confident about local population estimates from administrative sources. This analysis goes further than this work as it assesses how far healthcard data can produce reliable data products of the kind to which academics are accustomed. It does this by examining migration events versus transitions over a full intercensal period; population flows into and out of small areas; and the extent to which it produces microdata on migration equivalent to that in the census. It is shown that for most demographic groups and places healthcard data is an adequate substitute for census-based migration counts, the exceptions being for student households and younger people. However, census-like information is still needed to provide covariates for analysis and this will still be required whatever the future of the traditional census.

Two Phases

Objective: To establish if depression results in poor adherence to therapy in patients with heart diseases. Methods: This concept scoping study was conducted in two phases; the first was a systematic review of the literature, and the second part was local data analysis. Statistical analysis was performed using RevMan® V.5.3 (Cochrane Community). Results: Patients who received multidisciplinary collaborative care showed significantly reduced major adverse cardiac outcomes in patients with cardiovascular diseases. They also demonstrated higher rates of self-reported remission of depression. The review also showed endpoint mortality after PCI was associated with patients having depression. Local population data showed that 26% of heart failure patients had mental ill health comorbidity, however, only 12% had a formal diagnosis recorded. Conclusion: Depression is associated with poor cardiac outcomes in patients with coronary artery disease. It is widespread in patients with cardiovascular disease and must be screened for throughout the management plan.

Abstract. Background: Suicide is a serious problem in the Traveller community, with rates estimated at 11%: over 6 times that of the general population. Aims: We aimed to establish the prevalence and correlates of suicidal ideation (SI) and self-harm (SH) among Irish Travellers. Method: This was an observational cross-sectional cohort study of patients presenting with SH and SI to a tertiary hospital in Ireland, in an area with a large local Traveller population. Data were analyzed from the anonymized database ( n = 2,016), comparing characteristics of Travellers and the general population. Results: This study found that Travellers (1.6% of the local population) represent 4.3% of the population seen in hospital with SH and SI, and 14.8% of episodes. There was a significant difference in SH methods used: Travellers were significantly more likely to present following attempted hanging, ( OR = 21.8; p = .004). Travellers were more commonly diagnosed with depression or substance abuse, referred from critical care, and transferred for inpatient psychiatric treatment. Limitations: Limitations include the use of retrospective data from a service activity database rather than clinical information collected prospectively. Conclusion: There are significant differences in patterns of suicidal behaviors between Irish Travellers and the general population. Further research is required to understand and address the high rates of suicidal behaviors in this population.

Little has been published about Sminthopsis murina, a small insectivorous marsupial encountered infrequently during trapping studies. Individuals favour vegetation associations found in recently burnt heathlands and forests; however, individuals rarely remain in such areas long enough for repeated capture. We report an unusual occurrence of habitat fidelity by a dense population of subadult S. murina in coastal wet heath, New South Wales, Australia. Individuals were captured repeatedly in the first 16 months following wildfire (30 subadults trapped 154 times: recapture rate = 80%). Densities peaked 10 months after fire at 3.75 individuals ha–1. More males than females were captured (23 males, 7 females). Habitat analyses revealed differential use of regenerating coastal wet heathland by S. murina. Significantly more captures were made in areas of high soil moisture in the first six months following fire. Captures then decreased in these areas but increased where soil moisture had been lower and where vegetation had been growing more slowly. Beyond the 1995/96 breeding season, regenerating vegetation became increasingly dense and less patchy and captures of S. murina ultimately declined to zero. This paper records a rare opportunity to examine habitat preferences of a single cohort of subadult S. murina. Habitat use may have been determined by the presence of a narrow range of vegetation structure.

This study aims to find out how cooperation, competition, conflict and accommodation between transmigration living in the village of Werdhi Agung with indigenous people in Dumoga Sub-district. This study was conducted from December 2016 to February 2017, starting from preparation to the formulation of the research report. The data used in the form of primary data and secondary data. This research is done by purposive sampling technique. The total respondents in this study were 40 people, who were the head of the family, consisting of 20 members of the transmigrant group from Bali and 20 members of the indigenous Mongondow community representing the local population. Data analysis was done descriptively by using Likert Scale. The results show that: a) The cooperation between transmigrants and indigenous peoples is so harmonious that in their daily life it has reflected a broad assimilation / mixing form arising from the realization that they have common interests, both individually and in groups, they are aware that they have different ethnic cultural backgrounds. This has a positive effect on the social life of transmigration communities and indigenous peoples in coexistence. b) Competition between transmigrants and indigenous people is marked by land ownership / social jealousy competition and competition between village youth but no competition or threat of violence. c) Conflicts between transmigrants and indigenous peoples only occur in land tenure, and the conflicts are not frequent among rural youth. d) Accommodation or work to end disputes or conflicts between conflicting parties ie between transmigrants and indigenous peoples can be resolved either through the family or with the help of villagers and government officials.

The release of global gridded population datasets, including the Gridded Population of the World (GPW), Global Human Settlement Population Grid (GHS-POP), WorldPop, and LandScan, have greatly facilitated cross-comparison for ongoing research related to anthropogenic impacts. However, little attention is paid to the consistency and discrepancy of these gridded products in the regions with rapid changes in local population, e.g., Mainland Southeast Asia (MSEA), where the countries have experienced fast population growth since the 1950s. This awkward situation is unsurprisingly aggravated because of national scarce demographics and incomplete census counts, which further limits their appropriate usage. Thus, comparative analyses of them become the priority of their better application. Here, the consistency and discrepancy of the four common global gridded population datasets were cross-compared by combing the 2015 provincial population statistics (census and yearbooks) via error-comparison based statistical methods. The results showed that: (1) the LandScan performs the best both in spatial accuracy and estimated errors, then followed by the WorldPop, GHS-POP, and GPW in MSEA. (2) Provincial differences in estimated errors indicated that the LandScan better reveals the spatial pattern of population density in Thailand and Vietnam, while the WorldPop performs slightly better in Myanmar and Laos, and both fit well in Cambodia. (3) Substantial errors among the four gridded datasets normally occur in the provincial units with larger population density (over 610 persons/km2) and a rapid population growth rate (greater than 1.54%), respectively. The new findings in MSEA indicated that future usage of these datasets should pay attention to the estimated population in the areas characterized by high population density and rapid population growth.
