A review of motivational climate in physical activity.

Here we provide, within a social-cognitive framework, a critical review of research on the motivational impact of different psychological climates in physical activity. Motivational, cognitive, affective and behavioural outcomes are considered in sport, school physical education and exercise. We first review laboratory and field studies that tried to manipulate the perceived structures of motivational environments and to examine the subsequent outcomes on participants' cognitive and affective responses. Then we discuss studies influenced by the work of Ames in classroom settings and involving questionnaires to measure individuals' perceptions of 'motivational climates'. The impact of mastery and performance climates on various indices of motivation is narratively reviewed, and statistically estimated effect sizes from 14 studies (n = 4484) are presented as supporting evidence. We conclude that a mastery motivational climate is associated with more adaptive motivational patterns, while a performance climate is linked with less adaptive or maladaptive motivational and affective responses. Future research should determine the personal and situational variables that can moderate the impact of such relationships. Furthermore, a broader perspective is proposed, to understand the creation of perceived motivational climates, which is based on the integration of political, cultural, coaching and parental influences.

A longitudinal perspective of the relationship between perceived motivational climate, goal orientations, and strategy use.

Achievement goal theory suggests that goal orientations and the perceived motivational climate may influence one another and other motivational variables over time. Therefore, the purpose of this study was threefold: (a) to examine the relationship between perceived motivational climate and goal orientations over time (b) to investigate how goal orientations may fluctuate when the climate was in opposition to the initial goal orientation, (c) to determine how the climate may impact practice strategies. A set of inventories was administered to 162 college students at preselected times throughout several 16-week physical activity classes. Changes occurred in students' goal orientations, particularly when the perceived motivational climate was in opposition to their goal orientation. Aspects of the task-involving climate positively predicted practice strategies.

Human Adaptation to Work in Two Different Climates.

The processes of acclimation to hot-dry and to warm-humid climates were studied using two approaches: a quantitative analysis of literature data and an experimental study in the laboratory concerning the physiological parameters of heart rate, rectal temperature, sweat loss, and subjective assessment. Analysis o f literature data: Data from 62 experiments with a total of 813 participants were pooled and recalculated. The experiments ranged from 6 to 24 days, air temperatures from 30.4 to 50.0°C, water vapor pressures from 1.5 to 6.5 kPa, and wet bulb globe temperatures (WBGT) from 27.4 to 38.6°C. Laboratory studies: In the laboratory, 8 participants were acclimated during 15 consecutive days to a hot-dry climate and to a warm-humid climate, which were equivalent in terms of the WBGT (33.5 and 33.6°C, respectively). The participants walked four times for 25 min on a treadmill at a speed of 4 km/h. The hot-dry climate caused somewhat greater strain than the warm-humid condition. In the course of acclimation to the hot-dry climate, heart rate and rectal temperature started at higher levels, decreased slightly steeper but remained on a higher level throughout. Nevertheless, the differences between both thermal conditions were small, and both physiologic functions reached the point of acclimation almost at the same time under warm-humid and under hot-dry exposure. Sweat loss, which is not regarded as a valid predictor for acclimation, was considerably higher but increased less in the hot-dry than in the warm-humid climate.

A typology of social climates in group residential facilities for older people.

A typology of the social climates of group residential facilities for older people was developed by a cluster analysis of seven social climate attributes obtained on a national sample of 235 nursing homes, residential care facilities, and congregate apartments. The analysis yielded six distinct types of social climate: Supportive, Self-Directed; Supportive, Well-Organized; Open Conflict; Suppressed Conflict; Emergent-Positive; and Unresponsive. Facility and resident characteristics were related to social climate type. In addition, the type of social climate was related to resident adaptation. Supportive, Self-Directed and Supportive, Well-Organized facilities had residents who rated higher in well-being and levels of self-initiated activities and who used fewer health services. A configural approach to describing social climates and their determinants and effects may help to develop more humanistic residential facilities and to better match individual residents to appropriate housing placements.

Effects of elevated CO(2), nutrition and climatic warming on bud phenology in Sitka spruce (Picea sitchensis) and their impact on the risk of frost damage.

Effects of elevated CO(2), clone and plant nutrition on bud dormancy of Sitka spruce (Picea sitchensis (Bong.) Carr.) were examined. Sitka spruce seedlings were fumigated with ambient or elevated (ambient + 350 micro mol mol(-1)) concentrations of CO(2) in open-top chambers for three growing seasons. In 1991 and 1992, elevated CO(2) delayed bud burst in the spring and advanced bud set in the autumn. The effect of the open-top chamber on the thermal requirement for bud burst was greater than the effect of elevated CO(2) (50 and 30 day degrees (D(d)), respectively). In a second study, four clones of Sitka spruce taken from two provenances, at 43 and 54 degrees N, were fumigated with ambient or elevated CO(2). There was a large natural variation in the timing of bud burst and bud set among the clones. Elevated CO(2) had no effect on bud dormancy of the Skidegate a clone, but it reduced the growing season of the North Bend b clone by 20 days. In a third study, Sitka spruce seedlings growing in ambient or elevated CO(2), were supplied with one of three nutrient regimes, low (0.1 x potential), medium (0.5 x potential) or high (2.0 x potential), using a method and solution based on the Ingestad technique. Elevated CO(2) did not affect bud dormancy in the high-nutrient treatment, but it reduced the growing season of plants in the low-nutrient treatment by 22 days. Increasing plant nutrient supply lengthened the growing season, plants flushed earlier in the spring and set bud later in the autumn. The effects of elevated CO(2) plus a 0, 2 or 4 degrees C climatic warming on the timing of bud burst and the subsequent risk of frost damage were assessed using a simulation model and meteorological data from three sites, Edinburgh, Braemar and Masset. The model predicted that (i) doubling the CO(2) concentration in the absence of climatic warming, will delay the onset of bud burst at all three sites, (ii) climatic warming in ambient CO(2) will hasten bud burst and (iii) climatic warming in elevated CO(2) will hasten bud burst at Edinburgh and Braemar but to a lesser extent than climatic warming alone. At Masset, a 4 degrees C warming was required to advance the date of bud burst of seedlings in the elevated CO(2) treatment. At all three sites, elevated CO(2) and climatic warming increased the mean daily temperature on the date of bud burst, thus reducing the risk of subsequent frost damage.

Forest decline: modeling the effect of climate in tree rings.

Tree rings provide an historical record of forest growth that reflects changes with time in site factors including, competition, tree and stand age, fire and other disturbances, and climate. Statistical methods can be used to factor out climatic influences on radial growth to yield a climate response model that can indicate whether declines in forest productivity are related to the modeled climatic variables or to other influences such as atmospheric pollutants. A general method, based on ordinary least squares, is presented for creating climatic response models for forest decline studies. The crux of the method is model verification, whereby the time-stability of the model is tested before it is used to forecast tree-ring variations during a period of decline. Three studies are described that employ monthly mean temperatures to predict tree-ring indices in declining red spruce (Picea rubens Sarg.) stands in the Appalachian Mountains of North America. The results indicate that, since 1960, red spruce trees at most of the sites sampled have undergone a period of growth decline that is unrelated to changes in mean monthly temperature. However, an association between annual ring width and unusual departures from the mean summer and winter temperatures during both present and past periods of decline suggests that climatic effects are implicated to some degree in the current decline.

Social climate within secure inpatient services for people with intellectual disabilities.

BACKGROUND: The social climate of inpatient facilities is thought to be an important contributor to treatment outcome. However, little research has focused on this construct within secure forensic services for people with intellectual disabilities (ID). Therefore, the objective of this study was to investigate the social climate of two different types of secure units ('low' secure vs. 'medium' secure) contained within the same facility for offenders with ID. Two hypotheses were generated: (1) residents would rate the social climate of the whole facility in a more negative direction than staff, and (2) residents and staff would rate the social climate of the 'low' secure unit in a more positive direction than that of the 'medium' secure unit. METHOD: Using a 2 (factor 'Participant' = Staff or Resident) x 2 (factor 'Unit' = 'Low' or 'Medium' Secure Unit) between-subjects design, 18 residents and 37 staff members were recruited and completed the Correctional Institutions Environment Scale (CIES), a measure of social climate. RESULTS: Residents tended to rate the units in a more positive direction than staff on some sub-scales. Participants rated the 'low' secure unit in a more positive direction than the 'medium' secure unit on two sub-scales of the CIES. However, on selected sub-scales there were differences. The findings of this study suggest that the CIES may be a valid instrument for use within forensic services for people with ID, and further suggests that residents and staff have different perceptions of the shared social climate, which may have implications for service development.

Local initiatives and adaptation to climate change.

Climate change is expected to lead to an increase in the number and strength of natural hazards produced by climatic events. This paper presents some examples of the experiences of community-based organisations (CBOs) and non-governmental organisations (NGOs) of variations in climate, and looks at how they have incorporated their findings into the design and implementation of local adaptation strategies. Local organisations integrate climate change and climatic hazards into the design and development of their projects as a means of adapting to their new climatic situation. Projects designed to boost the resilience of local livelihoods are good examples of local adaptation strategies. To upscale these adaptation initiatives, there is a need to improve information exchange between CBOs, NGOs and academia. Moreover, there is a need to bridge the gap between scientific and local knowledge in order to create projects capable of withstanding stronger natural hazards.

Cultural circuits of climate change in U.K. broadsheet newspapers, 1985-2003.

This article argues for a cultural perspective to be brought to bear on studies of climate change risk perception. Developing the "circuit of culture" model, the article maintains that the producers and consumers of media texts are jointly engaged in dynamic, meaning-making activities that are context-specific and that change over time. A critical discourse analysis of climate change based on a database of newspaper reports from three U.K. broadsheet papers over the period 1985-2003 is presented. This empirical study identifies three distinct circuits of climate change-1985-1990, 1991-1996, 1997-2003-which are characterized by different framings of risks associated with climate change. The article concludes that there is evidence of social learning as actors build on their experiences in relation to climate change science and policy making. Two important factors in shaping the U.K.'s broadsheet newspapers' discourse on "dangerous" climate change emerge as the agency of top political figures and the dominant ideological standpoints in different newspapers.

Modern global climate change.

Modern climate change is dominated by human influences, which are now large enough to exceed the bounds of natural variability. The main source of global climate change is human-induced changes in atmospheric composition. These perturbations primarily result from emissions associated with energy use, but on local and regional scales, urbanization and land use changes are also important. Although there has been progress in monitoring and understanding climate change, there remain many scientific, technical, and institutional impediments to precisely planning for, adapting to, and mitigating the effects of climate change. There is still considerable uncertainty about the rates of change that can be expected, but it is clear that these changes will be increasingly manifested in important and tangible ways, such as changes in extremes of temperature and precipitation, decreases in seasonal and perennial snow and ice extent, and sea level rise. Anthropogenic climate change is now likely to continue for many centuries. We are venturing into the unknown with climate, and its associated impacts could be quite disruptive.

Safety climate and its association with injuries and safety practices in public hospitals in Costa Rica.

In response to growing concern for occupational health and safety in the public hospital system in Costa Rica, a cross-sectional survey of 1,000 hospital-based health care workers was conducted in 1997 to collect baseline data that are being used to develop worker training programs in occupational health in Costa Rica. The objectives of this survey were to: 1) describe the safety climate within the national hospital system, 2) identify factors associated with safety, and 3) evaluate the relationship between safety climate and workplace injuries and safety practices of employees. The safety climate was found to be very poor. The two most significant predictors of safety climate were training and administrative support for safety. Safety climate was a statistically significant predictor of workplace injuries and safety practices, respectively, and there was an underreporting rate of 71% of workplace injuries. These findings underscore the need for improvement of the safety climate in the public hospital system in Costa Rica.

Motivational climate and attitudes to change: a hospital study.

Change can be highly motivating when it is perceived as results-oriented, well planned and well communicated. However, there appears to be a lack of evidence on the actual existence of such relationships between motivational climate and attitudes to change in management literature, especially under the specific conditions of health care organisations in Slovakia. Using a sample of 243 employees of the University Hospital Bratislava, the present study has investigated the validity of the assumption that: (i) low motivational climate will represent an inhibitor to change, and vice versa, (ii) the more attention is being paid by the organisation's management to implementation of change, resulting in the staff having positive attitudes to change, the higher the motivational climate within the organisation will be. The findings indicate that motivational climate of the hospital can be heavily influenced by the manner in which the change is being managed. Moreover, not only how change is being managed, but also how it is understood and accepted by the employees, as well as which outcomes the change results in, have significant effects on the perceived motivational climate. The results also show that to maintain the high motivational climate, thus stimulating desired behaviours in the staff, the hospital managers should keep, among other things, (i) encouraging the workers to make a creative contribution, (ii) informing them about the reasons why changes are being made, (iii) showing them how their work objectives relate to where the hospital is heading and that the cost of the current changes will not outweight the benefits, and (v) ensuring that adequate training is available to equip people for changes and giving them the support they need to cope with change. Last, but not least, the present study helps to demonstrate the importance of attitudes as a force that is powerful in determining work output. (Tab. 3, Ref. 37.)

[The effect of a high-altitude climate on the function of the respiratory system in children with asthma].

In 108 asthmatic children (age 6-15 years) an effect of the 6-8 weeks stay in the High Tatra mountains (Children's Lung Institute, Dolný Smokovec) on lung function was studied in the years of 1985-1988. The patients consisted of groups followed-up in different periods of the latter years. Indications for the stay was airway obstruction (a.o.) in symptom-free period or bronchial hyperreactivity (b.h.) before starting the stay. The effect of climate on a.o. and b.h. was assessed from the parameters, measured from maximum expiratory flow-volume (MEFV) curves. Mean MEFV curves and their areas were considered as indices of the climate effect on a.o. and b.h. in the studied groups of asthmatics during the stay in the Institute. B.h. was assessed according to the induced a.o. after 5 min. free running outdoors. Mean MEFV curves and their areas did not differ significantly at the start and end of the stay in this high mountains climate. However, the MEFV curves significantly differed after the induced a.o. by 5 min. free running at the start and end of this climate therapy. The descendent parts and areas under the curves were reduced much less after the induced a.o. during and the end of stay than at the start of stay. They proved a decrease of bronchial hyperreactivity in all studied groups of asthmatics in the climate of High Tatra. The degree of bronchial hyperreactivity, tested as a magnitude of a.o. following 5 min. free running outdoors, on the basis of parameters from MEFV curves, appeared as an objective measure of climate therapy effect on lung function in our asthmatic children.

[Influence of climatic factor on formation and development of TCM].

Climatic factors influence health, physiological and pathological condition of human being, and then influence medicine. Through discussing the relationship between climatic type and traditional Chinese medical theory, relationship between climatic changes and formation and development of Cold-Warm School, and regional characteristic of Ling Nan medicine, conclusion can be made: firstly, traditional Chinese medical theory has some regional limit because its formation was influenced by climatic factor; secondly, climatic changes in history is the important cause leading to formation and vicissitude of Cold-Warm School in TCM history; thirdly, as an important branch of TCM, Ling Nan medicine reflects its own climatic characteristic and shows good adaptability and promising prospects of TCM.

Targeting attention on local vulnerabilities using an integrated index approach: the example of the climate vulnerability index.

It is known that climate impacts can have significant effects on the environment, societies and economies. For human populations, climate change impacts can be devastating, giving rise to economic disruption and mass migration as agricultural systems fail, either through drought or floods. Such events impact significantly, not only where they happen, but also in the neighbouring areas. Vulnerability to the impacts of climate change needs to be assessed, so that adaptation strategies can be developed and populations can be protected. In this paper, we address the issue of vulnerability assessment through the use of an indicator approach, the climate vulnerability index (CVI). We show how this can overcome some of the difficulties of incommensurability associated with the combination of different types of data, and how the approach can be applied at a variety of scales. Through the development of nested index values, more reliable and robust coverage of large areas can be achieved, and we provide an indication of how this could be done. While further work is required to improve the methodology through wider application and component refinement, it seems likely that this approach will have useful application in the assessment of climate vulnerability. Through its application at sub-national and community scales, the CVI can help to identify those human populations most at risk from climate change impacts, and as a result, resources can be targeted towards those most in need.

Measurement of the nurse organizational climate of neonatal intensive care units.

The concept of organizational climate is important for the study and understanding of work organizations. Researchers have not yet studied the organizational climate of hospital intensive care units, so it is not clear that the dimensions useful in description of other work settings will be appropriate for conceptualizing neonatal intensive care units (NICU's). This study investigated nurse perceptions of the organizational climate of NICU's in a sample of 18 hospitals. The Organizational Climate Description Questionnaire was modified for use in the NICU setting. A set of homogeneous climate scales was developed from the revised instrument. The six scales of the resulting instrument, the Nursing Organizational Climate Description Questionnaire, Form B (NOCDQ-B), demonstrated median internal-consistency reliability of .69 on cross-validation. Analysis of variance indicated that each of the six NOCDQ-B dimensions served to differentiate the NICU's in the study. Further, significant relationships were found at the unit mean level between three of the six NOCDQ-B scales and nurse satisfaction, as measured by the Minnesota Satisfaction Questionnaire.

Impacts of Climate Change and Related Weather Events on the Health and Wellbeing of Culturally and Linguistically Diverse Communities: A Systematic Review.

BACKGROUND: Vulnerable populations such as culturally and linguistically diverse communities (CALD), ethnic minorities and racial groups face a disproportionate burden of climate change-related health impacts due to a combination of socio-cultural and economic factors, geographic vulnerabilities and health disparities. This review synthesised the existing evidence on the health and wellbeing impacts of climate change and related weather events among CALD communities. METHODS: A narrative synthesis approach was utilised to conduct a systematic review. Three electronic databases (PubMed, Scopus and Web of Science) were searched, identifying 25 studies for appraisal and synthesis. Studies published in the English language from January 2010 to March 2024 were included in the review. RESULTS: The reviewed studies, mostly carried out in the USA, employed varied study designs, and focused on diverse CALD groups such as migrants, farmworkers and racial and ethnic minorities. The included studies addressed broader and specific climate change-related events, ranging from heat-related impacts and hurricanes to occupational heat exposure. CALD communities were found to be more vulnerable to climate change-related negative physical and mental health issues, further exacerbated by poor living conditions, limited access to healthcare, and cultural and language barriers. CONCLUSION: Future efforts by governments, healthcare agencies, employers and research institutions should prioritise multilingual risk communication strategies, providing culturally appropriate health education and healthcare access, housing improvements and the investigation of long-term health impacts of climate change and coping mechanisms adopted among CALD populations.

PREDICTOL: a computer program to determine the thermophysiological duration limited exposures in various climatic conditions.

PREDICTOL is a PC program used to determine the thermophysiological duration limited exposures (DLE) in humans, nude or clothed, submitted to various climatic conditions (hot and cold climates) at rest or during a physical exercise. DLE are determined following different standards of the International Standardization Organization (ISO), especially ISO 7933 for hot environment and ISO-TR 11079 for cold environment. The original aspect of this program is that it can be used whatever the climatic conditions. The program presents two modes: an educational interactive mode and a scenario mode. The educational interactive mode demonstrates the thermophysiological effects, expressed as DLE, of different parameter changes (temperature, humidity, wind speed, metabolic heat production by physical exercise, clothing insulation and water vapor permeability). The scenario mode determines DLE for given various linked sequences as encountered in occupational, military or even recreational activities, each sequence being characterized by its climatic conditions, physical activities performed and by physical clothing properties. DLE given by PREDICTOL are correlated to those obtained in various controlled climatic laboratory conditions (r = 0.86; P < 0.001). PREDICTOL is written in Visual Basic 6.0. A "help menu" is provided to explain the use of the program and give information concerning the equations used to calculate both the thermal balance and DLE.
