Unpacking Police Endorsement of Myths Surrounding Intimate Partner Violence Against Women: Formation and Implications.

Drawing on a qualitative case study consisting of interviews with Danish police trainees, patrol officers, and police detectives, this article explores police endorsement of myths surrounding male-perpetrated intimate partner violence against women (IPVAW) and its influence on police response to IPVAW incidents. The findings show that police officers begin to believe in the myths to cope with negative emotions arising from repeated exposure to IPVAW victims, who do not behave according to expected norms of being cooperative, responsible, and innocent. This makes police officers meet victims with skepticism, low spirit, and hopelessness, making them refrain from initiating further criminal investigations, opening criminal cases, and pursuing arrests.

Hydrothermal liquefaction of Spirulina and Nannochloropsis salina under subcritical and supercritical water conditions.

Six hydrothermal liquefaction experiments on Nannochloropsis salina and Spirulina platensis at subcritical and supercritical water conditions (220­375 °C, 20­255 bar) were carried out to explore the feasibility of extracting lipids from wet algae, preserving nutrients in lipid-extracted algae solid residue, and recycling process water for algae cultivation. GC­MS, elemental analyzer, FT-IR, calorimeter and nutrient analysis were used to analyze bio-crude, lipid-extracted algae and water samples produced in the hydrothermal liquefaction process. The highest bio-crude yield of 46% was obtained on N. salina at 350 °C and 175 bar. For S. platensis algae sample, the optimal hydrothermal liquefaction condition appears to be at 310 °C and 115 bar, while the optimal condition for N. salina is at 350 °C and 175 bar. Preliminary data also indicate that a lipid-extracted algae solid residue sample obtained in the hydrothermal liquefaction process contains a high level of proteins.

Community exercise program use and changes in healthcare costs for older adults.

BACKGROUND: Regular exercise is associated with many health benefits. Community-based exercise programs may increase exercise participation, but little is known about cost implications. METHOD: A retrospective, matched cohort study was conducted to determine if changes in healthcare costs for Medicare-eligible adults who choose to participate in a community-based exercise program were different from similar individuals who did not participate. Exercise program participants included 1114 adults aged > or = 65 years, who were continuously enrolled in Group Health Cooperative of Puget Sound (GHC) between October 1, 1997 and December 31, 2000 and who participated in the Lifetime Fitness (exercise) Program Copyright (LFP) at least once; three GHC enrollees who never attended LFP were randomly selected as controls for each participant by matching on age and gender. Cost and utilization estimates from GHC administrative data for the time from LFP enrollment to December 31, 2000 were compared using multivariable regression models. RESULTS: The average increase in annual total healthcare costs was less in participants compared to controls (+642 dollars vs +1175 dollars; p=0.05). After adjusting for differences in age, gender, enrollment date, comorbidity index, and pre-exposure cost and utilization levels, total healthcare costs for participants were 94.1% (95% confidence interval [CI], 85.6%-103.5%) of control costs. However, for participants who attended the exercise program at an average rate of > or = 1 visit weekly, total adjusted follow-up costs were 79.3% (95% CI, 71.3%-88.2%) of controls. CONCLUSIONS: Including a community exercise program as a health insurance benefit shows promise as a strategy for helping some Medicare-eligible adults to improve their health through exercise.

Effectiveness of telephone support in increasing physical activity levels in primary care patients.

BACKGROUND: Physician counseling of patients to increase physical activity has had limited success in changing behavior. Providing organizational support to primary care providers and their patients may increase effectiveness. OBJECTIVE: This study evaluates the effectiveness of a telephone-based intervention to increase physical activity among patients who exercised <15 minutes daily and wanted to increase their physical activity over a 6-month period. DESIGN: This was a randomized controlled trial, conducted from 1997 to 1998, of 316 patients aged 18 to 65 who were recruited from a mailed health risk assessment. Baseline and 6-month post-intervention telephone assessments were conducted by telephone. SETTING: One family physician's patients in a suburban community. INTERVENTION: Three sessions of telephone-delivered motivational counseling. MAIN OUTCOME MEASURES: Physical activity score (11-item Physician-Based Assessment and Counseling for Exercise [PACE]) 6 months after the intervention. RESULTS: After adjusting for baseline exercise, there was a significantly higher level of self-reported exercise among individuals randomized to the intervention at the 6-month follow-up. The mean level of activity at follow-up for the intervention group was a PACE score of 5.37, compared to 4.98 in the control group (p<0.05). In the secondary analysis, which was limited to individuals who received the intervention, the effect was stronger (PACE score of 5.58 compared to 4.94, p<0.013). CONCLUSIONS: Patients can be recruited using a health-screening questionnaire to receive a telephone-delivered behavioral intervention to successfully increase their physical activity levels.
