Activating Worksites to Implement Policy, Systems, and Environmental Changes: Outcomes and Overcoming Challenges.

PURPOSE: Although workplaces are prime settings for health promotion, little is known about the implementation of policy, systems, and environmental (PSE) changes focused on chronic disease. PSEs have broader reach and are more sustainable than individual level strategies. DESIGN: non-experimental, one group design with no control.Setting: West Virginia, a state with significant chronic disease-related health disparities. SUBJECTS: Convenience sample of 27 workplaces, representing 6 industry types. INTERVENTION: $1000 in micro funding awarded to workplaces to participate in Centers for Disease Control and Prevention (CDC) Work@Health®/ScoreCard, and implement PSEs. MEASURES: ScoreCard baseline results; post project survey results. ANALYSIS: Descriptive analysis of ScoreCard; survey responses coded into PSE and I (individual level strategies) categories; frequencies were calculated. RESULTS: 63% of the workplaces were very small (1-100 employees). Chronic disease-related organizational practices (ScoreCard) were minimal: nutrition (5/24), physical activity (7/22), diabetes (5/15), cholesterol (4/13), and high blood pressure (6/16). Workplaces reported a total of 95 PSEs: P-8, S-55, and E-32. CONCLUSION: Policy change was the least frequently attempted and reported PSE strategy. More research with a stronger study design is needed to determine if (1) baseline organizational practices (Scorecard scores) improve, (2) PSEs (especially P) can be implemented without micro funding/TA, (3) workplace-type is related to use of the funds/TA, and (4) enacting PSE changes leads to healthier employees.

Spacing and Mate Attraction: Sex-Specific Function of Advertisement Calls in the Northern Giant Mouse Lemur (Mirza zaza).

It has been proposed that primates use advertisement calls exclusively to negotiate spacing, but the function of female calls has rarely been studied. Here, we investigated the function of male and female advertisement calls in the northern giant mouse lemur (Mirza zaza),a non-gregarious nocturnal primate from north-western Madagascar. We recorded advertisement calls and associated behaviours of 35 M. zaza individuals at the Duke University Lemur Center. We found that females of M. zazaexclusively use their advertisement calls to advertise oestrus. In contrast, male advertisement calls appeared to be used in a spacing context. These findings show that primates can use their advertisement calls for both spacing and mate attraction, and that the sexes may differ in how they use these calls. The novel find of females of M. zazaattracting mates with loud advertisement calls contrasts with many non-primate taxa, where acoustic mate attraction is usually a function of male advertisement calls, and with other primates, where females use visual and olfactory cues to attract males. The loud female advertisement calls of M. zaza likely ensure mating success during the short receptive phase in this non-gregariously foraging, nocturnal primate.

Effect of Stress Level on Different Forms of Self-Touch in Pre- and Postadolescent Girls.

Self-touch serves for regulation of both hyper- and hypoarousal. It remains unclear if different forms of self-touch occur in different contexts, and if the regulatory mechanisms are learned or innate. The authors describe forms and context of self-touch, and explore age differences in stress processing. They analyzed hand movements of 10 pre- and 10 postadolescent girls in low-stress and high-stress settings and found 3 forms of self-touch. In postadolescent participants, self-touch 2 (irregular structure, rhythmical, medium intensity) and 3 (phasic structure, single accent, medium intensity) were used for self-regulation, whereas self-touch 1 (irregular structure, single accent, low intensity) had conversational reasons. Increasing immobility might represent the inward focus of stressed participants that tried to focus on the task. No differences were found for preadolescent participants. Differences between pre- and postadolescent participants might be due to brain development during adolescence.

Interspecific semantic alarm call recognition in the solitary Sahamalaza sportive lemur, Lepilemur sahamalazensis.

As alarm calls indicate the presence of predators, the correct interpretation of alarm calls, including those of other species, is essential for predator avoidance. Conversely, communication calls of other species might indicate the perceived absence of a predator and hence allow a reduction in vigilance. This "eavesdropping" was demonstrated in birds and mammals, including lemur species. Interspecific communication between taxonomic groups has so far been reported in some reptiles and mammals, including three primate species. So far, neither semantic nor interspecific communication has been tested in a solitary and nocturnal lemur species. The aim of this study was to investigate if the nocturnal and solitary Sahamalaza sportive lemur, Lepilemur sahamalazensis, is able to access semantic information of sympatric species. During the day, this species faces the risk of falling prey to aerial and terrestrial predators and therefore shows high levels of vigilance. We presented alarm calls of the crested coua, the Madagascar magpie-robin and aerial, terrestrial and agitation alarm calls of the blue-eyed black lemur to 19 individual Sahamalaza sportive lemurs resting in tree holes. Songs of both bird species' and contact calls of the blue-eyed black lemur were used as a control. After alarm calls of crested coua, Madagascar magpie-robin and aerial alarm of the blue-eyed black lemur, the lemurs scanned up and their vigilance increased significantly. After presentation of terrestrial alarm and agitation calls of the blue-eyed black lemur, the animals did not show significant changes in scanning direction or in the duration of vigilance. Sportive lemur vigilance decreased after playbacks of songs of the bird species and contact calls of blue-eyed black lemurs. Our results indicate that the Sahamalaza sportive lemur is capable of using information on predator presence as well as predator type of different sympatric species, using their referential signals to detect predators early, and that the lemurs' reactions are based on experience and learning.
