A theoretical framework and research agenda for studying team attributions in sport

The attributions made for group outcomes have attracted a great deal of interest in recent years. In this article we bring together much of the current research on attribution theory in sport and outline a new conceptual framework and research agenda for investigating the attributions of team members. The proposed framework draws on multiple conceptual approaches including models of attribution, group dynamics and stress responses to provide a detailed hypothetical description of athletes' physiological, cognitive and affective responses to group competition. In describing this model we outline important antecedents of team attributions before hypothesising how attributions can impact hormonal and cardiovascular responses of athletes, together with cognitive (goals, choices, expectations), affective (self-esteem, emotions), and behavioural (approach-avoidance actions) responses of groups and group members. We conclude by outlining important methodological considerations and implications for structured context specific attribution-based interventions

Relationship between perceived physical ability and sport participation motives in young competitive swimmers.

ObjectivesTo develop a questionnaire, the Geriatric In-hospital Nursing Care Questionnaire (GerINCQ), to measure, in an integrated way, the care that older adults receive in the hospital and nurses' attitudes toward and perceptions about caring for older adults. DesignQuestionnaire development. SettingTwelve university and teaching hospitals. ParticipantsThirteen experienced geriatric nurses and three geriatricians from 12 hospitals evaluated an initial version of the questionnaire. Two hundred seventy-one nurses, primarily registered nurses from 11 geriatric, medical, and surgical departments in six hospitals, validated the final questionnaire. MeasurementsItems from two published instruments were extracted for use in the questionnaire. Content validity was confirmed using the Delphi technique with an expert panel. Internal consistency was measured by calculating Cronbach alpha; intrarater reliability was measured using test-retest correlations and intraclass correlation coefficients (ICCs); differences between hospital departments were analyzed using analysis of variance. Sensitivity to detect before-and-after changes with implementation of a geriatric care program was determined using the Student t-test. ResultsConsensus was reached after three Delphi rounds. The GerINCQ is a self-administered questionnaire to be filled out by hospital nurses that comprises five subscales with 67 items. It has good content validity (each item content validity index >0.9) and good internal consistency (Cronbach alpha=0.86). Intrarater reliability revealed high test-retest results (ICC=0.87). The questionnaire detected significant differences between nurses in three types of hospital departments (medical, surgical, and geriatric (P ConclusionThe GerINCQ is a reliable and valid tool and is sensitive to change over time. It is clinically relevant because it provides a quantitative measure of hospital nurses' geriatric practices, attitudes, and perceptions. Moreover, the GerINCQ is suitable for monitoring progress after implementation of geriatric improvement programs

Nitrogen fixation in preserved, reforested, naturally regenerated and impaired mangroves as an indicator of functional restoration in mangroves in an arid region of Mexico

Although several damaged mangrove ecosystems have been restored worldwide, so far, it has not been established whether a restored mangrove system regains all the functional properties of preserved mangroves. This study measured nitrogen fixation as an indicator of whether disturbed mangroves that were reforested or naturally regenerated fully recovered from this disturbance at a functional level. Rates of nitrogen fixation were measured for one year in impaired, preserved, reforested, and naturally regenerated mangroves dominated by the black mangrove (Avicennia germinans). There was no significant difference in rates of nitrogen fixation among preserved and adjacent reforested and naturally regenerated mangroves, but a significant reduction occurred in an impaired mangrove. Nitrogen fixation was mainly controlled by pH, salinity, and temperature. The highest rates of nitrogen fixation occurred in summer at pH values less than 6.4, whereas the impaired mangrove had higher pH and salinity and had very low nitrogen fixation activity. These results suggest that nitrogen fixation can be used as an ecological indicator of the success of reforestation and as a sensitive measure of perturbations in mangroves
