Tax Credits and the Use of Medical Care

Several recent proposals have advocated using the income tax system to collect user fees to help fund the health care system. While there is a considerable amount of research investigating both how individuals respond to tax incentives for employer provided health insurance and on the effects of user fees payable at the point of service on the use of health care services, there is limited evidence on how individuals respond to tax incentives when these are not realized until taxes are paid. This paper uses existing exemptions in the Canadian tax code that allow individuals to deduct the cost of health care or health insurance from their taxable income in order to identify the tax price elasticity of demand for health care when price changes are realized at the end of the tax year. Our results suggest that despite not realizing the tax benefit at the time of purchase, individuals are quite responsive to changes in the tax price of health care. Our elasticity estimates for a wide range of health care products are well within the range of traditional price elasticity estimates, including in particular our estimates for prescription drugs. We also find some evidence that suggests individuals trade off risk sharing through traditional insurance companies with risk sharing through the tax code. That is, as the tax price of health care decreases, individuals spend more on health care, but spend less on health insurance.

Foxes, voles and waders: drivers of predator activity in wet grassland landscapes

Impacts of generalist predators on declining prey populations are a major conservation issue, but management of this situation is constrained by limited knowledge of the factors influencing predator distribution and activity. In many declining populations of ground-nesting waders, high levels of nest and chick predation are preventing population recovery. Red foxes, Vulpes vulpes, are the main predator but their primary prey is small mammals. On wet grasslands managed for breeding waders, small mammals are concentrated in tall vegetation outside of fields, and nests closer to these patches are less likely to be predated. To assess whether these patterns result from fox attraction to small mammals, and thus the potential for management of tall vegetation to influence nest predation rates, we quantify seasonal and spatial variation in fox and small mammal activity in relation to tall vegetation patches. Across wet grassland sites, tall vegetation patches of any size (> 0.05 ha) supported small mammals and small mammal activity increased throughout the wader breeding season, while the use of fox track plots within fields declined seasonally. Although within field fox track plot use did not vary with distance to tall vegetation, over the 1064 nights of trail camera recording, foxes were seen in areas with tall vegetation on 13 nights compared with short vegetation on only two nights. These findings suggest that lower predation rates of lapwing nests close to tall vegetation could reflect fox attraction to areas with small mammal activity, but any such effects would primarily operate later in the breeding season, and may therefore primarily influence late nests and chicks

Where do we go from here? An assessment of navigation performance using a compass versus a GPS unit

The Global Positioning System (GPS) looks set to replace the traditional map and compass for navigation tasks in military and civil domains. However, we may ask whether GPS has a real performance advantage over traditional methods. We present an exploratory study using a waypoint plotting task to compare the standard magnetic compass against a military GPS unit, for both expert and non-expert navigators. Whilst performance times were generally longer in setting up the GPS unit, once navigation was underway the GPS was more efficient than the compass. For mediumto long-term missions, this means that GPS could offer significant performance benefits, although the compass remains superior for shorter missions. Notwithstanding the performance times, significantly more errors, and more serious errors, occurred when using the compass. Overall, then, the GPS offers some clear advantages, especially for non-expert users. Nonetheless, concerns over the development of cognitive maps remain when using GPS technologies

Photoperiodic effects on precocious maturation, growth and smoltification in Atlantic salmon, Salmo salar

Current Atlantic salmon farming practice induces early smoltification with artificial photoperiod regimes, however the importance of these photoperiods on parr maturation and interactions with smoltification are poorly understood. These questions were addressed in the present investigation, which examined the effects of photoperiod manipulation on the development, maturation and smoltification of individually tagged parr. Approximately 9000 salmon parr from a high grilsing stock were exposed to continuous light (LL) from first feeding. Three sub-groups of 2400 parr, each sub-group in triplicate tanks, were then exposed to an 8 week “winter photoperiod” (LD 10:14) starting on either the 18th May, the 9th August or the 20th September (defined respectively as the May, August and September groups). Following the artificial winter each group was returned to LL. A fourth group of 1600 fish was maintained in replicate tanks on LL throughout. The highest levels of maturation (approx. 20%) were recorded in the May group. August and September groups showed low levels of maturity

CAST: Proximity broadcasting as a mode of news distribution in rural Armenia

CAST (DisCovery Amplification Sustainability and InTeractions) has trialled a new community communication network in rural Armenia developing models to emerge alternative news media in a highly politically pressured national state. The project was a collaboration between the Media Innovation Studio, UK, Impact Hub Yerevan and SMART Edge Platform provider WICASTR™, Yerevan. The project also ran with the support of the United Nations Development Programme, award-winning investigative journalism outlet Hetq, and Civilnet from the Civilitas Foundation. It was a three-phase year-long pilot that ran in 2016 and 2017, funded by the UK Higher Education Innovation Fund. The aim was to: Build a lightweight community connectivity system for content distribution Generate proximity insights: new data analytics that allow publishers to pinpoint what content is consumed where Facilitate novel approaches to digital literacy by creating engaged digital communities New knowledge and impact have been created around: How to build hyperlocal proximity networks using online to offline wifi technology Future scoping information systems for remote communities New hyperlocal news data analytics for publishers Novel methods to add to media plurality in a highly politically pressured environment Strategies to improve digital literacy and community communication that can challenge a digital divid

Correlates of physical activity among people living with and without HIV in rural Uganda

Background Antiretroviral therapy (ART) has led to diminishing AIDS-related mortality but a concomitant increase in non-communicable diseases (NCDs) for people with HIV (PWH). Whereas physical activity (PA) has been shown to help prevent NCDs and NCD outcomes in other settings, there are few data on PA and its correlates among PWH in high-endemic settings. We aimed to compare PA by HIV serostatus in rural Uganda. Methods We analysed data from the UGANDAC study, an observational cohort including PWH in ambulatory HIV care in Mbarara, Uganda, and age- and gender-matched people without HIV (PWOH). Our primary outcome of interest was PA, which we assessed using the International Physical Activity Questionnaire and considered as a continuous measure of metabolic equivalents in minutes/week (MET-min/week). Our primary exposure of interest was HIV serostatus. We fit univariable and multivariable linear regression models to estimate the relationship between HIV and PA levels, with and without addition of sociodemographic and clinical correlates of PA (MET-min/week). In secondary analyses, we explored relationships restricted to rural residents, and interactions between gender and serostatus. Results We enrolled 309 participants, evenly divided by serostatus and gender. The mean age of PWH was 52 [standard deviation (SD) 7.2] and 52.6 (SD 7.3) for PWOH. In general, participants engaged in high levels of PA regardless of serostatus, with 81.2% (251/309) meeting criteria for high PA. However, PWOH reported higher mean levels of PA met-minutes/week than PWH (9,128 vs 7,152, p ≤ 0.001), and a greater proportion of PWOH (88.3%; 136/154) met the criteria for high PA compared to PWH (74.2%; 115/155). In adjusted models, lower levels of PA persisted among PWH (β = −1,734, 95% CI: −2,645, −824, p ≤ 0.001). Results were similar in a sensitivity analysis limited to people living in rural areas. Conclusion In a rural Ugandan cohort, PWOH had higher levels of PA than PWH. Interventions that encourage PA among PWH may have a role in improving NCD risk profiles among PWH in the region

Early life cognitive function and health behaviours in late childhood: testing the neuro-selection hypothesis

Background: Higher cognitive function in childhood is associated with healthier behaviours and a reduced risk of chronic disease in adulthood, but it is unclear whether this selection of healthier behaviours occurs in childhood or later in life. The present study investigated how cognitive function at age 3-7 years was associated with health behaviours at age 11. Methods: Verbal, non-verbal and spatial abilities were assessed using the British Ability Scales at ages 3-7. At age 11, children reported how often they engaged in sport/physical activity, sedentary behaviours (e.g. reading and games console usage), cigarette smoking and alcohol consumption. Logistic regression was used to estimate odds of engaging in health behaviours at age 11 according to early life cognition. Results: A one standard deviation increase in early childhood verbal ability was associated with reduced odds of attempting smoking by age 11 in boys and girls (OR 0.69 [95% CI 0.57, 0.84]) and reduced odds of computer gaming in girls (OR 0.79 [95% CI 0.72, 0.86]). Verbal ability was also associated with reduced odds of regular participation at age 11 in sport/active games and increased odds of reading for enjoyment. Non-verbal ability was associated with reduced odds of alcohol consumption in boys and girls (OR 0.92 [95% CI 0.85, 0.99]) and reduced odds of online messaging (OR 0.89 [95% CI 0.81, 0.98]). Spatial ability was associated with reduced odds of participating in sport/active games in boys. Conclusion: Neuroselection may occur during early life resulting in some, but not all, healthier behaviours

Dialogic assessment in the context of professional recognition: perspectives from the canoe

This paper draws on the reflective evaluations of four experienced academic practitioners who each have roles in leading or contributing to Fellowship Schemes in a UK context (United Kingdom Professional Standards Framework, 2011) and are all Advance HE accreditors. The focus for the evaluation was the use of a dialogic approach within their respective Fellowship Schemes. The aim of the project was to better understand the conditions in which dialogues can thrive, and to surface the challenges. A collective autoethnographic method was decided upon to frame the evaluative process. Four one-hour online meetings were scheduled over a period of six weeks. The data were transcribed and analysed using a mind-map process and resulted in the emergence of a metaphor – that of a canoe trip in which five phases were identified: designing the vessel, getting aboard, settling in/ settling down, navigating the space and forward-wash. These five phases are overviewed here with the intention of provoking discussion in the academic practice community, drawing into conversation individuals who are concerned with assessment for learning generally, and those who have particular interest in the potential of dialogic assessments which culminate in a summative judgement. It adds to the literature focused on assessment in higher education by drawing to the fore the conditions in which dialogic approaches can thrive for the individual being assessed, while also facilitating reciprocal learning

RMAVIS v1.0: a Shiny application for the analysis of vegetation survey data and assignment to GB NVC communities

RMAVIS is a Shiny application for the assignment of vegetation sample plot data to British National Vegetation Classification (NVC) communities (Rodwell, 1991, 1992a, 1992b, 1995, 2000). The assignment of vegetation sample plot data to established vegetation classification units using computational methods is a well established and recognised practice (Maciejewski et al., 2020). The results of this assignment process are used in various ways, including assisting in the phase 2 habitat survey (or NVC survey) process (Rodwell, 2006); establishing an ecological baseline and identifying important ecological features such as protected habitats (CIEEM, 2022); and in ecological restoration by providing a proxy for historical reference ecosystems to target and against which to measure restoration progress (Gann et al., 2019; Pywell et al., 2002; Sturbois et al., 2023). In Great Britain (GB) the development of computational methods and programs for the assignment of vegetation survey data to NVC communities began with the development of TABLEFIT (Hill, 1989; Marrs, 2019) and was followed by MATCH (Malloch, 1998). The most recent program, the Modular Analysis of Vegetation Information System (MAVIS), was developed as a windows application in 2000 and was a DEFRA-funded output of the ECOFACT project (Bunce et al., 1999), with the latest version released in 2016 (Smart et al., 2016)
