Despite the wealth of accumulated research evaluating subjective wellbeing (SWB) in children and adults, the validity of scores from parallel forms of SWB measures for each age group has yet to be empirically tested. This study examines the psychometric equivalence of the child and adult forms of the personal wellbeing index (PWI) using multiple-group confirmatory factor analysis. The child sample comprised 1,029 Victorian high-school students (aged 11–20) sampled across three independent studies. The adult sample comprised 1,965 Australian adults drawn from the Australian Unity Wellbeing Index. The results demonstrated strict factorial invariance between both versions, suggesting that the PWI measures the same underlying construct in adolescent and adult populations. These findings provide support for quantitative comparisons between adult and adolescent SWB data as valid.  相似文献

Although the term drought is widely used, defining it is conceptually and technically difficult and there is no generally accepted definition. This article uses data from an Australian social survey of people living in agricultural areas to test the validity of using general social surveys to ask respondents whether they are living in an area that is drought affected. Strong evidence is found that the survey based self-report measure of drought is both internally consistent and correlated with the standard Australian meteorological (rainfall deficit) measures of drought and thus provides a valid measure of whether individuals are experiencing the drought. The relationship between self-report drought and the standard meteorological measure of drought and financial hardship and changes in financial position is estimated. While a negative association between drought and financial position is found for both measures, the relationship is stronger for the self-report than the meteorological definition. The self-report measure is more closely linked to the economic, social and community impacts of low rainfall and provides greater flexibility in the geographic area over which drought is measured—thus survey data about drought allows respondents to define the area in way which is meteorologically, topographically or agriculturally meaningful.  相似文献

Educational inequalities in health behaviors change dynamically across the life course. Yet, how parental and personal education interactively shape age-specific behavioral inequalities across the transition to adulthood has yet to be understood. Drawing on national Add Health data (N?=?12,605; 6,675 women and 5,930 men), we analyze age- and gender-specific trajectories of current smoking and binge drinking from adolescence to young adulthood. In line with previous work, we find that parental education associates with smoking and drinking disparities even after respondents’ own education is completed. Reciprocally, we also find that disparities by eventual educational attainment appear early. During the college years, higher parental education predicts higher—not lower—rates of binge drinking. We find that attaining higher education “against the odds” of an educationally disadvantaged family background circumscribes the lowest rates of smoking and drinking for men and women alike, and especially during the college years, while “falling from grace” by not attaining higher education at levels matching one’s parents predicts the highest levels of smoking and drinking for both genders during or after college. These results shed new light on the interactive socioeconomic processes that help to explain behavioral health gradients across adolescence and adulthood.

Peer Pressure     
We present a model where agents care about their neighbors' actions and can pressure them to take certain actions. Exerting pressure is costly for the exerting agent and it can impact the pressured agents by either lowering the cost of taking the action (which we call “positive pressure”) or else by raising the cost of not taking the action (which we call “negative pressure”). We show that when actions are strategic complements, agents with lower costs for taking an action pressure agents with higher costs, and that positive pressure can improve societal welfare. More generally, we detail who gains and who loses from peer pressure, and identify some circumstances under which pressure results in fully (Pareto) optimal outcomes as well as circumstances where it does not. We also point out differences between positive and negative pressure. (JEL: Z13, D62, C72, D85)  相似文献

Swearwords influence social evaluation of a speaker in a variety of ways depending on social context (Jay & Janschewitz (2008), The pragmatics of swearing. Journal of Politeness Research. Language, Behaviour, Culture, 4(2), 267–288). Little attention has been paid to the role of linguistic variation in social perceptions of swearing, however. This paper presents two experiments that test the role of sociolinguistic variation in the social evaluation of swearing. Experiment 1 is a variant categorization task, in which participants categorized acoustically ambiguous swearwords and phonetically matching neutral and nonwords as ending in either “-ing” or “-in.” Results suggest that swearwords led participants to hear “-ing” on ambiguous items. Experiment 2 is a matched-guise task in which listeners heard a passage featuring a mix of swearwords and neutral “-ing” words in one of four conditions: fully velar (All-ing), fully alveolar (All-in), only swearwords as velar (Swear-ing), or only neutral words as velar (Swear-in). Participants rated speakers on Likert scales (Schleef et al. (2017), Regional diversity in social perceptions of (ING). Language Variation and Change, 29(1), 29–56). Participants again displayed a tendency towards hearing “-ing” on swearwords. As a result, responses to the Swear-in guises were similar to those for the All-ing guises. The consequences for our understanding of swearing, sociolinguistic perception and cognition, and style, are discussed.  相似文献

BackgroundGinger has been used throughout the world as a therapeutic agent for centuries. The herb is increasingly used in Western society also, with one of the most common indications being pregnancy-induced nausea and vomiting (PNV).ObjectivesTo examine the evidence for the safety and effectiveness of ginger for PNV.MethodsRandomised controlled trials (RCTs) of ginger and PNV were sourced from CINAHL, the Cochrane library, MEDLINE and TRIP. The methodological quality of RCTs was assessed using the Critical Appraisal Skills Programme (CASP) tool.ResultsFour RCTs met the inclusion criteria. All trials found orally administered ginger to be significantly more effective than placebo in reducing the frequency of vomiting and intensity of nausea. Adverse events were generally mild and infrequent.ConclusionThe best available evidence suggests that ginger is a safe and effective treatment for PNV. However, there remains uncertainty regarding the maximum safe dosage of ginger, appropriate duration of treatment, consequences of over-dosage, and potential drug–herb interactions; all of which are important areas for future research.  相似文献

Level of education is a predictor of a range of important outcomes, such as political interest and cynicism, social trust, health, well-being, and intergroup attitudes. We address a gap in the literature by analyzing the strength and stability of the education effect associated with this diverse range of outcomes across three surveys covering the period 1986–2011, including novel latent growth analyses of the stability of the education effect within the same individuals over time. Our analyses of the British Social Attitudes Survey, British Household Panel Survey, and International Social Survey Programme indicated that the education effect was robust across these outcomes and relatively stable over time, with higher education levels being associated with higher trust and political interest, better health and well-being, and with less political cynicism and less negative intergroup attitudes. The education effect was strongest when associated with political outcomes and attitudes towards immigrants, whereas it was weakest when associated with health and well-being. Most of the education effect appears to be due to the beneficial consequences of having a university education. Our results demonstrate that this beneficial education effect is also manifested in within-individual changes, with the education effect tending to become stronger as individuals age.  相似文献

Contextualized educational programs nested within career pathways provide instruction aimed at improving academic and vocational skills in the context of learning about a specific career or occupation. When the emphasis is on vocational training, contextualized education is commonly referred to as integrated instruction. This review provides an overview of the conceptual motivation and major elements of the career pathways and contextualized education approaches, with an emphasis on integrated instruction. This conceptual framework is used as the basis for conducting a detailed review of the important elements, operation, and empirical evidence of various local implementations of the Integrated Basic Education and Skills Training (I-BEST) model. We focus on variants of the I-BEST model, initially conceived and implemented in Washington, because it is the most widely known application of these approaches. Although several evaluations of Washington’s program found it to be more effective than traditional alternatives, we find little empirical evidence in support of the short-term local variants implemented elsewhere. This review provides important considerations for program administrators and policymakers as well as observations regarding gaps in knowledge regarding program operation and outcomes that deserve additional research.  相似文献

Local food systems (LFSs) are complex and diverse social structures. The processes that influence the formation and evolution of LFSs are obscure, relatively uncoordinated, and somewhat mysterious. This study develops a stronger understanding of such processes through a qualitative exploration of the influence of routine practice work at the organization level on the entrepreneurial development of two distinct LFSs in the Southwest region of the United States: southeastern Arizona and Albuquerque?Santa Fe. We gathered data between August 2014 and September 2017 through semistructured interviews with and direct observations of 53 local food practitioners operating in one of the two LFSs. Theoretical principles of institutional entrepreneurship, embedded agency, and practice work guided the study. The findings reveal three forms of ingenuity (technological, organizational, policy) that regularly emerge through the day‐to‐day organization‐level work of local food practitioners. We argue that the system‐level influence of these forms, whether intentional or not, are indicators of the embedded agency of the practitioners and their capacities to serve as institutional entrepreneurs. We discuss implications for both practice and future research.  相似文献
