    Effective alcohol policies are associated with reduced consumption among demographic groups who drink heavily.
    (Wiley Periodicals LLC on behalf of Research Society on Alcohol, 2023-04-23) Casswell S; Huckle T; Parker K; Graydon-Guy T; Leung J; Parry C; Torun P; Sengee G; Pham C; Gray-Phillip G; Callinan S; Chaiyasong S; MacKintosh AM; Meier P; Randerson S
    BACKGROUND: Alcohol policies stand out among other noncommunicable disease-relevant policies for the lack of uptake. Composite indicators have been developed to measure the effects of alcohol control policy. We investigated whether drinking patterns among demographic groups from general population samples of drinkers from diverse countries are associated with alcohol control policy as measured by the International Alcohol Control (IAC) Policy Index. METHODS: Representative samples of adult drinkers from 10 countries (five high-income and five middle-income) were surveyed about alcohol consumption, using beverage and location-specific questions. MEASUREMENTS: The IAC Policy Index was analyzed with frequency, typical occasion quantity, and volume consumed. Analyses used mixed models that included interactions between country IAC Policy Index score and age group, gender, and education level. FINDINGS: Each increase in IAC policy index score (reflecting more effective alcohol policy) was associated with a 13.9% decrease in drinking frequency (p = 0.006) and a 16.5% decrease in volume (p = 0.001). With each increase in IAC Policy Index score, both genders decreased for all three measures, but men less so than women. Women decreased their typical occasion quantity by 1.2% (p = 0.006), frequency by 3.1% (p < 0.001), and total volume by 4.2% (p < 0.001) compared to men. Low and mid-education groups decreased their typical occasion quantity by 2.6% (p < 0.001) and 1.6% (p = 0.001), respectively, compared to high education, while for drinking frequency the low education group increased by 7.0% (p < 0.001). There was an overall effect of age (F = 19.27, p < 0.0001), with 18-19 and 20-24-year-olds showing the largest decreases in typical occasion quantity with increasing IAC policy index score. CONCLUSIONS: The IAC Policy Index, reflecting four effective policies, was associated with volume and frequency of drinking across 10 diverse countries. Each increase in the IAC Policy Index was associated with lower typical quantities consumed among groups reporting heavy drinking: young adults and less well-educated. There is value in implementing such alcohol policies and a need to accelerate their uptake globally.

    Can survival analyses detect hunting pressure in a highly connected species? Lessons from straw-coloured fruit bats.
    (2016-08) Hayman DTS; Peel AJ
    Animal behaviour, social structure and population dynamics affect community structure, interspecific interactions, and a species' resilience to harvesting. Building on new life history information for the straw-coloured fruit bat (Eidolon helvum) from multiple localities across Africa, we used survival analyses based on tooth-cementum annuli data to test alternative hypotheses relating to hunting pressure, demography and population connectivity. The estimated annual survival probability across Africa was high (≥ 0.64), but was greatest in colonies with the highest proportion of males. This difference in sex survival, along with age and sex capture biases and out-of-phase breeding across the species' distribution, leads us to hypothesize that E. helvum has a complex social structure. We found no evidence for additive mortality in heavily hunted populations, with most colonies having high survival with constant risk of mortality despite different hunting pressure. Given E. helvum's slow life history strategy, similar survival patterns and rate among colonies suggest that local movement and regional migration may compensate for local excess hunting, but these were also not clearly detected. Our study suggests that spatio-temporal data are necessary to appropriately assess the population dynamics and conservation status of this and other species with similar traits.

    Migrant construction workers’ demography and job satisfaction: A New Zealand study
    (Emerald, 2021) Rotimi JOB; Ramanayaka C; Olatunji O; Rotimi FE
    Purpose: The demand for construction-related occupations has increased consistently over many years in New Zealand (NZ). This has necessitated recourse to migrant workers to address capacity and capability requirements. Migrant construction workers hail from various backgrounds with a complex set of their needs being met through employment in NZ. Research on understanding the satisfaction levels of this category of construction workers is scarce. With recent insinuations about migrant exploitations, research investigations into this knowledge area are significant. In this study, the authors sought to establish the moderating effect of migrants' demography on the determinants of job satisfaction in NZ's construction sector. Design/methodology/approach: Data were obtained from migrant construction workers of Chinese extraction through a structured questionnaire survey. From 200 questionnaires administered, 108 samples were completed by migrant construction workers involved in major projects in Auckland city, NZ. Data obtained were analysed using descriptive and inferential statistics to establish the moderating effects of their demography on job satisfaction. Findings: Results from this study support the internal validity and reliability of these personal characteristics as moderators of job satisfaction for migrant construction workers. These results suggest the relevance of personal characteristics of Chinese migrants in any improvement initiatives being developed for this group of construction workers. Research limitations/implications: The findings from this study contribute to the discourse on the relevance of construction migrants as a strategic alternative to addressing skill shortages within the NZ construction sector. They also provide evidence that contributes to an improved understanding of the migrant workforce to meet their aspirations and enhance their general well-being. Originality/value: Although the study is ethnic-specific, the conclusions show the relevance of personal characteristics in the experiences of construction migrant workers. The study is representative of the catchment of temporary migrant workers in the construction industry in NZ. The study provides insights for organisations employing migrants about putting in place appropriate measures to enhance their satisfaction levels. Finally, this study's findings may contribute to policy initiatives on the optimal categories of migrants engaged on construction activities to derive the maximum benefits for NZ.
