Relationship of Self-Determination Theory Constructs and Physical Activity and Diet in a Mexican American Population in Nueces County, Texas

Due to disparities in stroke risk among U.S. Hispanics, the need for culturally tailored, theory based effective health behavior change interventions persists. The purpose of this study was to examine self-determination theory (SDT) constructs related to cardiovascular disease (CVD) risk factors in a predominantly Mexican American population. The Stroke Health and Risk Education (SHARE) project was a cluster-randomized, faith-based behavioral intervention trial that enrolled Mexican Americans (MAs) and non-Hispanic whites (NHWs) from Catholic Churches in Nueces County, Texas. Data regarding SDT constructs and dietary and physical activity behaviors were collected via computer-assisted interviews using standardized instruments at the baseline assessment. Of the 801 subjects who consented, 760 completed baseline interviews. After eliminating cases with missing data, 733 participants (617 MA and 116 NHW) were included in the analyses. Participants were predominantly Mexican American (84%) and female (64%), and had a median age of 53 years. There were no significant ethnic differences in any of the baseline SDT scale scores with the exception of higher autonomous motivation scores for exercise among MAs (7.00 vs. 6.67, p = 0.01). Demographic differences in mean SDT scale scores were identified for sex, age, and income. Perceived competence and autonomous motivation were both significant predictors of diet and physical activity behaviors. This study increases our understanding of SDT constructs relative to diet and physical activity in a large, predominantly Mexican American sample. The results indicate that SDT is an appropriate framework to address CVD behavioral risk factors in a predominantly Hispanic population

Beyond ecosystem modeling: a roadmap to community cyberinfrastructure for ecological data‐model integration

In an era of rapid global change, our ability to understand and predict Earth's natural systems is lagging behind our ability to monitor and measure changes in the biosphere. Bottlenecks to informing models with observations have reduced our capacity to fully exploit the growing volume and variety of available data. Here, we take a critical look at the information infrastructure that connects ecosystem modeling and measurement efforts, and propose a roadmap to community cyberinfrastructure development that can reduce the divisions between empirical research and modeling and accelerate the pace of discovery. A new era of data‐model integration requires investment in accessible, scalable, transparent tools that integrate the expertise of the whole community, including both modelers and empiricists. This roadmap focuses on five key opportunities for community tools: the underlying foundationsof community cyberinfrastructure; data ingest; calibration of models to data; model‐data benchmarking; and data assimilation and ecological forecasting. This community‐driven approach is key to meeting the pressing needs of science and society in the 21st century

'Trafficking' or 'personal use': Do people who regularly inject drugs understand Australian drug trafficking laws?

Introduction and Aims: Legal thresholds for drug trafficking, over which possession of an illicit drug is deemed 'trafficking' as opposed to 'personal use', are employed in all Australian states and territories excepting Queensland. In this paper, we explore the extent to which people who regularly inject drugs understand such laws. Design and Methods: Participants from the seven affected states/territories in the 2012 Illicit Drug Reporting System (n=823) were asked about their legal knowledge of trafficking thresholds: whether, if arrested, quantity possessed would affect legal action taken; and the quantities of heroin, methamphetamine, cocaine and cannabis that would constitute an offence of supply. Data were compared against the actual laws to identify the accuracy of knowledge by drug type and state, and sociodemographics, use and purchasing patterns related to knowledge. Results: Most Illicit Drug Reporting System participants (77%) correctly said that quantity possessed would affect charge received. However, only 55.8% nominated any specific quantity that would constitute an offence of supply, and of those 22.6% nominated a wrong quantity, namely a quantity that was larger than the actual quantity for supply (this varied by state and drug). Discussion and Conclusions: People who regularly inject drugs have significant gaps in knowledge about Australian legal thresholds for drug trafficking, particularly regarding the actual threshold quantities. This suggests that there may be a need to improve education for this population. Necessity for accurate knowledge would also be lessened by better design of Australian drug trafficking laws.

Deemed Supply in Australian Drug Trafficking Laws: A Justifiable Legal Provision?

In Australia, eight of the nine legal jurisdictions have enacted ‘deemed supply’ provisions for illicit drug trafficking offences that presume ‘intent to supply’ based on the quantity of a drug an alleged offender is found with and attach criminal liability for the offence of supply. Such laws have been enacted for more than 35 years. In this article we critically examine: the rationale for the widespread adoption of Australian deemed supply laws; and the justifiability and necessity of such laws in current legal practice. A legal and historical analysis was undertaken. Data were sourced from legislation, Parliamentary records (Hansard), case law, published research on international drug law, research on drug user behaviour and our own experience in the prosecution of drug offenders. Analysis shows that Australian deemed supply laws were introduced to overcome perceived difficulties in the prosecution and sanction of drug traffickers. Yet such laws conflict with the dominant international practice that sanctions trafficking without the use of deemed supply provisions. They contribute towards harms to users and miscarriages of justice and increase pressure to use police and prosecutorial discretion in ways that may ultimately adversely affect community confidence in the administration of the criminal law. We conclude that the laws should be subject to legislative review and/or, preferably, abolition from Australian drug trafficking law

Legislating thresholds for drug trafficking: A policy development case study from New South Wales, Australia

Background: Legal thresholds are used in many parts of the world to define the quantity of illicit drugs over which possession is deemed "trafficking" as opposed to "possession for personal use". There is limited knowledge about why or how such laws were developed. In this study we analyse the policy processes underpinning the introduction and expansion of the drug trafficking legal threshold system in New South Wales (NSW), Australia. Methods: A critical legal and historical analysis was undertaken sourcing data from legislation, Parliamentary Hansard debates, government inquiries, police reports and research. A timeline of policy developments was constructed from 1970 until 2013 outlining key steps including threshold introduction (1970), expansion (1985), and wholesale revision (1988). We then critically analysed the drivers of each step and the roles played by formal policy actors, public opinion, research/data and the drug trafficking problem. Results: We find evidence that while justified as a necessary tool for effective law enforcement of drug trafficking, their introduction largely preceded overt police calls for reform or actual increases in drug trafficking. Moreover, while the expansion from one to four thresholds had the intent of differentiating small from large scale traffickers, the quantities employed were based on government assumptions which led to "manifest problems" and the revision in 1988 of over 100 different quantities. Despite the revisions, there has remained no further formal review and new quantities for "legal highs" continue to be added based on assumption and an uncertain evidence-base. Conclusion: The development of legal thresholds for drug trafficking in NSW has been arbitrary and messy. That the arbitrariness persists from 1970 until the present day makes it hard to conclude the thresholds have been well designed. Our narrative provides a platform for future policy reform

DPMP briefing paper: Australian drug trafficking laws: guilty until proven innocent?

DPMP has produced a new briefing paper on Australian deemed supply laws. These laws operate in eight of nine Australian jurisdictions and sanction drug trafficking solely on the weight of drug on an alleged offender.Dr Caitlin Hughes and Professor Alison Ritter from the Drug Policy Modelling Program, NDARC, UNSW Australia, along with Nicholas Cowdery AM QC, former Director of Public Prosecutions in NSW have completed research into the laws. This raised a number of concerns about the laws. The briefing paper outlines the central findings and policy recommendations from this research.
