PUBLIC HEALTH NURSING, Issue 3 2005
Article first published online: 24 JUN 200
EDITOR's NOTE, The following reprint of the unsigned editorial for the April 1952 issue of Public Health Nursing describes the historical needs and the continuing development of school health nursing from the early to mid-20th century. Twenty-first century schools continue to deal with some of the same issues such as hunger, poor nutrition, and the adverse effects of overly burdensome work schedules on adolescent health and mental well-being. The goal, so optimistically anticipated by the editors of Public Health Nursing in 1952, of continuous, well-coordinated health supervision from birth to maturity continues to elude us. Of course, school nurses and other health personnel address problems not openly discussed in the 1950s,substance abuse, violence, sexually transmitted diseases, and teen pregnancy. The theme of this historical editorial is the power of advocacy,and the responsibility public health nurses have to use our talents to improve child health. [source]

Effects of climate on population fluctuations of ibex

GLOBAL CHANGE BIOLOGY, Issue 2 2008
VIDAR GRØTAN
Abstract Predicting the effects of the expected changes in climate on the dynamics of populations require that critical periods for climate-induced changes in population size are identified. Based on time series analyses of 26 Swiss ibex (Capra ibex) populations, we show that variation in winter climate affected the annual changes in population size of most of the populations after accounting for the effects of density dependence and demographic stochasticity. In addition, precipitation during early summer also influenced the population fluctuations. This suggests that the major influences of climate on ibex population dynamics operated either through loss of individuals during winter or early summer, or through an effect on fecundity. However, spatial covariation in these climate variables was not able to synchronize the population fluctuations of ibex over larger distances, probably due to large spatial heterogeneity in the effects of single climate variables on different populations. Such spatial variation in the influence of the same climate variable on the local population dynamics suggests that predictions of influences of climate change need to account for local differences in population dynamical responses to climatic conditions.

Creating supportive clinical learning environments: an intervention study

JOURNAL OF CLINICAL NURSING, Issue 1-2 2010
Amanda Henderson
Aim., To assess the impact of an intervention aimed to build capacity of registered nurses to enhance the clinical learning environment for undergraduate nursing students. Workplace learning is vital for the development of skills, attributes and knowledge of student nurses. Registered nurses need to be appropriately prepared to maximise student learning during clinical placement. Background., The quality of student learning during clinical practicum is largely dependent on interactions with ward staff. Design., A quasi-experimental design. Method., Measurement of students' perceptions of the psycho social learning environment during and outside of the intervention period was used to evaluate the capacity building intervention. The capacity building intervention consisted of interactive education in clinical areas over a six-week period for registered nurses in two acute surgical wards. Results., First, second and third year students (n = 62) who undertook their clinical practicum in the two surgical wards, before, during and six months after the capacity building intervention assessed the psycho-social learning environment at the time of their clinical practicum. Findings showed that students who undertook their clinical practicum during the intervention period rated the psycho-social clinical learning environment significantly higher than students who undertook their practicum at times outside of the intervention period. Conclusions., An experienced researcher/educator conducting capacity building sessions can effectively assist and support registered nurses to engage with students. Relevance to clinical practice., Capacity building sessions can improve practice, however, structures and processes that ensure continuation of practice change need to be embedded for improvements to be sustained.

Regional Climate Change: Trend Analysis of Temperature and Precipitation Series at Selected Canadian Sites

CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2000
J. Stephen Clark
Global climate change does not necessarily imply that temperature or precipitation is increasing at specific locations. The hypothesis of increasing temperature and precipitation trends associated with global climate change is tested using actual annual temperature and precipitation data for nine selected weather stations, spatially distributed across Canada. Vogelsang's (1998) partial sum and Woodward et al's (1997) bootstrap methods are used for testing for trend. Both methods suggest no warming in the Canadian temperature series except for Toronto, Ontario, which had significant increase over time, along with Moncton, New Brunswick, and Indian Head, Saskatchewan, which had marginal increases. There is no evidence of increasing trend in precipitation except for Moncton, New Brunswick, which had a significantly increasing trend. Thus, public policies designed to address the regional effects of climate change need to be adapted for a particular ecological zone, based on knowledge of the climate trends for that region, rather than on general global climate change patterns. Les changements climatiques à l'échelle planétaire ne signifient pas nécessairement que la température et les précipitations sont en augmentation dans des emplacements donnés. Nous avons testé I'hypothèse d'une assoviation de la tendance à la hausse de la température et des précipitations avec les changements climatiques planétaires à partir des données réelles de température et de précipitations obtenues à 9 stations d'observation climatique réparties dans les diverses régions du Canada. Nous utilisons, pour cefaire, la méthode des sommes partielles de Vogelsang (1998) et celle de rééchantillonnage bootstrap de Woodward et al (1997). Les deux méthodes ne révèlent aucun réchauffement de la température dans les séries chronologiques, sauf pour Toronto, en Ontario, où l'on constate une hausse significative en fonction du temps, ainsi que pour Moncton au Nouveau-Brunswick et Indian Head en Saskatchewan qui marquent de très légères augmentations. Rien n'indique une tendance à la hausse des précipitations, sauf à Moncton où se dessine une tendance significative dans ce sens. Les programmes publics destinés à faire face aux effets régionaux du changement climatique doivent donc être adaptés à chaque zone écologique particulière, à partir d"observations faites dans la région même, plutôt que de la configuration du changement climatique à l'échelle planétaire.
