The present study is a content analysis of crisis news frames found in 2006 crisis news coverage. A total of 247 news stories were analyzed to examine which of five news frames (attribution of responsibility, human interest, conflict, morality, and economic) and level of responsibility (individual and organizational level) were used by the media according to crisis type. While the attribution of responsibility frame was the most predominantly used in crisis news coverage, the use of each of the five frames depended on crisis type. The use of level of responsibility also varied by crisis type and was related to the five frames; individual level of responsibility was used more with morality, human interest, and attribution of responsibility frames. Implications and suggestions based on the results were discussed.  相似文献

Few studies have asked children directly about their experiences in out-of-home care. This study uses data collected from 180 nine- to-11-year-old children currently in out-of-home care who were asked about their perceptions and appraisals of out-of-home care. Analysis of variance and chi-square analyses were used to examine whether children's appraisals of their lives following removal from their families of origin differ as a function of age, gender, race/ethnicity, type and severity of maltreatment, length of time in out-of-home care, placement type, attachment to current caregivers, and rating of current caregiver/home. Youth who were sexually and emotionally abused, youth who were satisfied with their current caregivers and placements, and girls were more likely to state that their lives would have been worse had they remained with their families of origin. Youth who were physically abused were more likely to report that their lives would have remained the same. Children living in group care were more likely than those living in family foster care or with kin to report that their lives would have been better had they remained with their families of origin. Differences were not found between children living in family foster care and those living with kin nor did children's appraisals differ based on age, race, ethnicity, length of time in out-of-home care, neglect, or severity of maltreatment.  相似文献

Using Becker's theory of commitment, national longitudinal data on 1961 college graduates are analyzed to determine the effects of early work orientation and the situational attributes of full-time work experience, husband's attitude and income, and number of children on the probability of 1968 employment among white married women. Work orientation is an insignificant predictor of work status and remains insignificant even when bolstered by any of the above variables. Similarly, the statistical interaction of other pairs of predictors makes no contribution to the probability of wives' employment. In the additive model, neither work orientation nor work experience affects employment probability. Three marriage-family variables are significant predictors: favorable husband, low income husband and absence of children. The findings are consistent with Becker's theory of nonconscious commitment.  相似文献

Air pollution is a current and growing concern for Canadians, and there is evidence that ambient levels that meet current exposure standards may be associated with mortality and morbidity in Toronto, Canada. Evaluating exposure is an important step in understanding the relationship between particulate matter (PM) exposure and health outcomes. This report describes the PEARLS model (Particulate Exposure from Ambient to Regional Lung by Subgroup), which predicts exposure distributions for 11 age-gender population subgroups in Toronto to PM2.5 (PM with a median aerodynamic diameter of 2.5 microm or less) using Monte Carlo simulation techniques. The model uses physiological and activity pattern characteristics of each subgroup to determine region-specific lung exposure to PM2.5, which is defined as the mass of PM2.5 deposited per unit time to each of five lung regions (two extrathoracic, bronchial, bronchiolar, and alveolar). The modeling results predict that children, toddlers, and infants have the broadest distributions of exposure, and the greatest chance of experiencing extreme exposures in the alveolar region of the lung. Importance analysis indicates that the most influential model variables are air exchange rate into indoor environments, time spent outdoors, and time spent at high activity levels. Additionally, a "critical point" was defined and introduced to the PEARLS to investigate the effects of possible threshold-pathogenic phenomena on subgroup exposure patterns. The analysis indicates that the subgroups initially predicted to be most highly exposed were likely to have the highest proportion of their population exposed above the critical point. Substantial exposures above the critical point were predicted in all subgroups for ambient concentrations of PM2.5 commonly observed in Toronto after continuous exposure of 24 hours or more.  相似文献

Abstract

Three categories of work characteristics — employment expectations, job satisfaction, and job experiences — in addition to commonly considered family variables, are examined as influences on sustained employment between 1964 through 1968 for a national sample of college-educated wives, class of 1961. Number of children and husband's income have the strongest, and negative, effects on sustained employment. Additionally, two work characteristics, one work orientation measure (expectation of being employed during the preschool child stage), and one job satisfaction measure (overall job satisfaction) are significant, and positive, influences. No other variable pertaining to wives' work characteristics is significantly related to sustained employment Because the responses in the data set were collected in the 1960s, the data in this article can serve as a comparison point for subsequent studies.  相似文献
