This paper explored how imaginary audience and personal fable ideations contribute to adolescent indoor tanning intentions directly and indirectly through the way they shape pro-tanning attitude and association with peers who use tanning beds. Five hundred and ninety-five male (n = 207) and female (n = 387) adolescents, ranging in age from 11 to 19 (M = 16.87; SD = 1.34) years completed a cross-sectional survey. Measures included imaginary audience, personal fable (three dimensions: invulnerability, uniqueness, and omnipotence), pro-tanning attitude, association with peers who use tanning beds, and tanning bed use intentions. Bootstrapping analyses documented that imaginary audience ideations are indirectly associated with indoor tanning intentions through the mediation of pro-tanning attitude and association with peers who use tanning beds. Of the personal fable ideations, only invulnerability ideation is indirectly associated with indoor tanning intentions through the mediation of association with peers who use tanning beds. Design and evaluation of interventions and campaigns to reduce indoor tanning must be targeted to adolescents varying in imaginary audience ideations differently.  相似文献

It is well documented that newly arrived immigrants face a significant earnings gap relative to native‐born workers. One way for new immigrants to improve their relative labour market position upon arrival in a host country is to improve their educational credentials. According to signalling theory, a host‐country credential should provide employers with a proxy for true productivity on the job, leading to higher earnings. Using data from a Canadian longitudinal survey, we employ longitudinal growth‐curve techniques to estimate the effect of receiving a Canadian educational credential on the income growth of racial‐minority recent immigrants compared to native‐born Canadians. The results indicate that the earnings gap between recent immigrants and native‐born Canadians is significantly reduced with the attainment of a Canadian educational credential.  相似文献

The condition of independence between two generalized second degree polynomial statistics is worked out in this paper under the assumption that the covariance matrix of the underlying normal distribution may be singular. The covariance between two such forms is also worked out without the assumption of normality. The results are indicated in compact matrix form.  相似文献

PRE- AND POSTRETIREMENT EXPENSES: Before retirement, people pay FICA taxes, incur work-related expenses, and set aside money for retirement. But after retirement, most people have different financial obligations, and, as a result, retirees may still be able to maintain their level of preretirement well-being with very different income levels. Studying income, expenditures, and wealth-holding patterns together provides a more complete idea of how people are doing in terms of being able to afford retirement than arbitrary estimates such as income replacement ratios. UNIQUE DATA: This Issue Brief examines the expenditure patterns of the older section of the population. It uses data from the Consumption and Activities Mail Survey (CAMS), a supplement to the Health and Retirement Study (HRS), conducted by the Institute for Social Research at the University of Michigan, contains detailed expenditure data on 32 categories, and follows the same group of individuals over eight years In addition, the income and wealth data available in the HRS are used to establish the financial standing of older households. DECLINING EXPENSES: Household expenses steadily decline with age. With the age 65 expenditure as a benchmark, household expenditure falls by 19 percent by age 75, 34 percent by age 85, and 52 percent by age 95. HOME EXPENSES: Home and home-related expenses remain the single largest spending category for older Americans. On average, those over age 50 spend around 40-45 percent of their budget on home and home-related items. RISING HEALTH CARE EXPENSES: Health-related expenses are the second-largest component in the budget of older Americans. It is the only component which steadily increases with age. Health care expenses capture around 10 percent of the budget for those between 50-64, but increase to about 20 percent for those age 85 and over. DEMOGRAPHIC GROUPS: Singles, blacks, and high school dropouts do not have a sound financial standing in retirement. Their expenditures exceed their income and they hold very little financial wealth. The bottom income quartile, which includes mostly these demographic groups, has the weakest financial standing in retirement. LONG-TERM CARE and PRIVATE HEALTH INSURANCE: Long-term care and some form of private health insurance coverage have a significant effect on increased spending by older households.  相似文献

Governments in developing countries have encouraged private sector investment to meet the growing demand for infrastructure. According to institutional theory, the role of institutions is paramount in private sector development. A longitudinal dataset of 40 developing economies between 1990 and 2000 is used to test empirically how different institutional structures affect private investment in infrastructure, in particular its volume and frequency. The results indicate that property rights and bureaucratic quality play a significant role in promoting private infrastructure investment. Interestingly, they also suggest that countries with higher levels of corruption attract greater private participation in infrastructure.  相似文献

This paper tries to trace the background of the modern business paradigm. A business mind dominating the social mind has been the root cause of unethicality in an order, according to this paper. The solution could come from the liberation of the social mind through a process of mind engineering at the individual level. The paper suggests an active mechanism to inculcate values through a systematic process of mind engineering.  相似文献

The paper makes a few comments on the characterizations of the log-change index numbers, and then builds up a link between the log-change indexes and the factorial indexes (Stuvel's indexes). It is also suggestedinter alia that log-change index numbers tend to ignore the effect of interaction between price and quantity (consumption) on the expenditure, in contrast to what is admitted by the factorial model.  相似文献

In this paper we study the extent to which ethical social welfare orders on infinite utility streams can be continuous. For a class of metrics, we show that ethical preferences can be continuous if and only if the continuity requirement is in terms of a metric which satisfies a simplex condition. This condition requires that the distance from the origin to the unit simplex in the space of utility streams be positive. We use this characterization result to establish that the metric used by Svensson (Econometrica 48:1251–1256, 1980) induces the smallest topology for which there exist continuous ethical preferences. We thank an associate editor and two referees of this journal for their comments and suggestions.  相似文献
