English Several changes have posed increasing challenges for the active dissemination of research within the policy world: the evidence-based policy-making movement has led to a demand for the implications of research to be spelt out; rapid technological changes have offered new electronic methods for bringing research to the attention of policy makers, but have also created information overload; while modernisation of the policy process has led to an emphasis on outcomes and demonstrable effectiveness. This article provides a critique of three models of research dissemination; it concludes with some innovative examples and identifies key resources for planning and developing an active dissemination strategy.
Context Seasonal migration and movements of bats have important implications for their conservation. The southern bent-winged bat (Miniopterus orianae bassanii), a critically endangered cave-dwelling taxon in Australia, has been described as undertaking regional-scale migration between maternity and non-breeding caves. Aims To describe the seasonal cycle of movements by the southern bent-winged bat, including migration and congregation events of different sex- and age-classes in the population. Methods We tagged a total of 2966 southern bent-winged bats with passive integrated transponder (PIT) tags. Antennas were used to detect bats in flight at a major maternity cave and a key non-breeding cave in south-east South Australia, from January 2016 to August 2019. We used capture–resight histories to visualise population patterns and model the daily encounter probability for each sex- and age-class at the respective roost sites. Key results Bats congregated at the maternity cave for most of the year, with different seasonal patterns among sex- and age-classes. Seasonal movements were associated with behaviour over winter months: most of the population dispersed from the maternity cave from May and a staged return occurred among population classes from July through September. A previously undescribed movement occurred in adult females and juveniles each year: these classes left the maternity cave in late summer, when juveniles became independent, and returned in early mid-autumn, later undertaking winter dispersal. Complex underlying movements of individuals occurred throughout the year, with individuals able to fly 72 km between roosting caves in just a few hours. Conclusions Seasonal movements are a key aspect of the life history of this taxon. The newly reported movement of adult females and juveniles conforms to the maternal guidance hypothesis, whereby mothers guide their young to suitable non-breeding caves and hibernation sites. In addition to seasonal movements, some individuals moved 72 km between caves multiple times over short time periods, including on successive nights. This 72-km overnight flight distance more than doubles the previous distance used to inform management buffer zones. Extended congregation of bats at the maternity cave highlights resource limitation in the surrounding area as a potential threat to this population. Implications The dynamic nature of the population has implications for the management of emerging risks, including mortality at windfarms and potential rapid spread of the exotic white-nose syndrome.
Public health programs may be seriously affected in periods of federal retrenchment. During these times, state-based strategies provide an alternate pathway for advancing public health. A 12-year campaign to secure state support for a network of Centers of Excellence in Children's Environmental Health (CEH) promoting health of children across New York State is described. It was driven by rising rates of asthma, birth defects, developmental disorders, and other noncommunicable diseases in children; growing evidence associating hazardous environmental exposures with these conditions; and recognition that federal resources in CEH are insufficient. Critical campaign elements were (1) formation of a statewide coalition of academic health centers, health care providers, public health officials, community advocates, and other stakeholders; (2) bipartisan collaborations with legislative champions and government leaders; (3) assessment of the burden of developmental disorders and noncommunicable diseases associated with environmental exposures among children; (4) maps documenting the presence of environmental hazards in every county statewide; (5) iterative charting of a changing political landscape; and (6) persistence. The 2017 award of a 5-year, $10 million contract to establish Centers of Excellence in CEH demonstrates the value of this statewide strategy.
