Arsenic Exposure, Arsenic Metabolism, and Glycemia
Little information is available regarding the glycemic effects of inorganic arsenic (iAs) exposure in urban populations. We evaluated the association of total arsenic and the relative proportions of arsenic metabolites in urine with glycemia as measured by glycated blood hemoglobin (HbA1c) among 45 participants with prediabetes (HbA1c ≥ 5.7-6.4%), 65 with diabetes (HbA1c ≥ 6.5%), and 36 controls (HbA1c < 5.7%) recruited from an academic medical c…
Using electronic dental records to establish a surveillance system for dental decay in rural Western Alaska
An oral health surveillance system has been established in western Alaska using the Electronic Dental Record. High rates of ECC and FMDR were observed. This surveillance system will allow assessments of ECC prevalence and impact of dental interventions
Contraceptive use among HIV-infected women and men receiving antiretroviral therapy in Lusaka, Zambia
While FP-ART integration may be a promising strategy for increasing FP service uptake, such services must focus on assessing sexual activity and advocating for dual method use to increase effective contraceptive use and prevent unintended pregnancies
Safeguarding Political Guarantees in the Colombian Peace Process
This article discusses the lessons of previous peace processes between the government of Colombia and the Revolutionary Armed Forces of Colombia (farc). It has two policy implications. In regard to Colombia it suggests that safeguarding the lives of demobilised farc members is necessary for the current peace process to succeed, hence it proposes a hybrid Specialised Protection Force (spf). In terms of peace building the article discusses the chal…
Reflections in the Classroom
Reflective practice has become a key trope within debates around teaching and learning in higher education. Yet, beneath this anodyne rhetoric, teachers and students are being disciplined in a manner that aligns so-called standards and professional development with the corporate strategies of educational institutions. Educational developers who seek to promote standards and accountability in the learning environment enforce the practice of reflec…
Effects of separation and novelty on distress vocalizations and cortisol in the common marmoset (Callithrix jacchus)
In socially-bonding species, separation from familiar attachment figures is widely known to stimulate a physiological and behavioral stress response. This study investigated the hormonal and vocal responses of adult common marmosets to separation from familiar group members and to 24 hr of cohabitation with an unfamiliar opposite-sex conspecific. All subjects were removed from their home cages and placed into a novel environment for 20 min. In on…
Context and sex differences exist in the acoustic structure of phee calls by newly-paired common marmosets (Callithrix jacchus)
Captive common marmosets of all ages robustly produce a "separation" phee call during brief separations from their group. In contrast, a second structural variant, which may function as an intergroup call, is produced in the home cage primarily by the reproductive adults. A previous study found that postpubertal but nonreproductive offspring rarely produce phee calls when in the home cage with the natal group, yet these marmosets call frequently …
Longitudinal Association of Cardiovascular Reactivity and Blood Pressure in Samoan Adolescents
OBJECTIVE: The longitudinal association between blood pressure (BP) reactivity to a video game and resting BP 3 to 4 years later was investigated in 83 Samoan adolescents from American and (Western) Samoa as part of a multidisciplinary study of cardiovascular disease (CVD) risk in modern Samoans. METHODS: Participants ranged in age from 11 to 14 years at baseline, in 1992 to 1993, and 14 to 18 years at follow-up in 1996. Video game BP reactivity …
Social context affects phee call production by nonreproductive common marmosets (Callithrix jacchus)
Common marmosets produce two variants of their long call (phee call) in different situations. Intergroup calls are produced in territorial situations, and intragroup separation calls are produced by marmosets isolated from group members. Marmoset groups frequently include postpubertal, nonreproductive members; their roles in the spontaneous production of territorial vocalizations is unclear. This study analyzed the production of home cage phee ca…
Responses to natural and synthetic phee calls by common marmosets ( Callithrix jacchus )
Captive adult common marmosets ( Callithrix jacchus ) produce whistlelike “phee” calls in two contexts: in the home cage, where phee calls may function as part of territorial marking behavior, and when separated from social companions, where phee calls may function to reunite conspecifics. Natural and synthesized calls representing the acoustic structure of male and female calls in each context were presented to adult marmosets in a playback para…
Context and gender‐specific differences in the acoustic structure of common marmoset ( Callithrix jacchus ) phee calls
Captive adult common marmosets ( Callithrix jacchus ) produce whistle‐like “phee” calls in two contexts; in the home cage environment, phee calls may function as part of territorial marking behavior, and when animals are separated from social companions, phee calls may serve to reunite the group. Isolation phee calls tend to have more syllables than calls produced in the home cage by the same animals, and as a result, are longer in duration. The …
Preliminary observations on squirrel monkey ( Saimiri oerstedi ) vocalizations in Costa Rica
This study was an initial attempt to analyze quantitatively vocalizations from the Central American squirrel monkey, Saimiri oerstedi . Vocalizations were recorded in the wild at P. N. Corcovado ( S. o. oerstedi ). and at P. N. Manuel Antonio ( S. o. citrinellus ). Additional recordings were made from captive individuals of both subspecies. The acoustic structure of analyzed vocalizations resembled most closely the vocal repertoire of South Ameri…
