Privacy Advocacy in Libraries in the Age of Mass Surveillance

Alison Macrina is the founder and director of the Library Freedom Project, an initiative that aims to make real the promise of intellectual freedom in libraries. The Library Freedom Project trains librarians on the state of global surveillance, privacy rights, and privacy-protecting technology, so that librarians may in turn teach their communities about safeguarding privacy. In 2015, Alison was named one of Library Journal‘s Movers and Shakers. Read more about the Library Freedom Project at libraryfreedomproject.org.

A controlled clinical trial on the effects of motor intervention on balance and cognition in institutionalized elderly patients with dementia

Purpose: To analyse the effects of two interventions on the cognition and balance of institutionalized elderly people with mixed dementia.Methods: Fifty-four participants were allocated into three groups. Group 1 was assisted by an interdisciplinary programme comprising physiotherapy, occupational therapy and physical education. A physiotherapist alone carried out the intervention in group 2. Group 3 was considered as control. Assessors were blinded to guarantee the absence of bias. Cognitive functions were analysed with the Mini-Mental State Examination and the Brief Cognitive Screening Battery. Balance was assessed with the Berg Balance Scale and the Timed Get-Up-and-Go Test. Multiple analysis of variance (MANOVA) was used to test possible main effects of the interventions.Results: The results showed benefits on the balance of subjects in both groups 1 (F=3.9, P < 0.05) and 2 (F= 3.1, P < 0.05), compared with group 3. MANOVA did not indicate benefits on the cognitive functions between groups 1 and 3 (F= 1.1, P > 0.05) and groups 2 and 3 (F= 1.6, P > 0.05). However, univariate analysis indicated some benefits of the interdisciplinary intervention on two specific domains measured by the Brief Cognitive Screening Battery (F=26.5, P < 0.05; F= 4.4, P < 0.05).Conclusion: Six months of multidisciplinary or physiotherapeutic intervention were able to improve a person's balance. Although global cognition did not improve through treatment, when the intervention was carried out on a multidisciplinary basis we observed an attenuation in the decline of global cognition on two specific cognitive domains. Exercises applied in different contexts may have positive outcomes for people with dementia.

Dynamics of follicle populations and gonadotropin concentrations in fillies age two to ten months

Follicle populations and concentrations of circulating gonadotropins were studied during age 2-10 months in 10 spring-born pony fillies. Blood sampling and ultrasound scanning were done every 4 days and daily for four 30 day periods. During 5-12 weeks, FSH concentrations were lower in 6 fillies with follicles greater than or equal to 6 mm (mean +/- s.e. 1.4 +/- 0.1 ng/ml) than in 4 fillies with follicles <6 mm (2.8 + 0.3 ng/ml). The diameters and numbers of follicles and gonadotropin concentrations increased progressively during age 2-4 months. A plateau in follicle activity and reduced levels of gonadotropins occurred during 5-7 months. During 8-10 months, follicles grew to >10 mm and gonadotropin concentrations increased. Waves of follicular growth were identified during the 30 day periods by significant increases in the diameter of the 10 largest follicles. The waves did not partition into dominant and subordinate follicles. Results indicated an initial postnatal period of negative ovarian feedback, temporally related changes in gonadotropins and follicles for months 3-10, and development of follicles in waves.
