A set of hypotheses related to the importance of four types of perceived risks in nine product classes were examined. Simultaneously the relieving ability of nine risk-reducing strategies was investigated. Brand loyalty for the non-durable experience goods, money-back guarantee and store image for the durable experience goods and shopping for the search goods ranked among the best risk relievers. It was also showed that it is sometimes possible to predict from knowledge of the type of risk that is ranked as highest which risk reliever will be ranked as highest.  相似文献

Using data from the National Educational Longitudinal Study (NELS), this article investigates a number of hypotheses used to explain the relationship between family structure and adolescent drug use. In particular, using linked community‐level data, an explicit examination of hypotheses drawn from a community‐context model is conducted. These hypotheses posit that the impact of family structure on adolescent behavior is, in part, explained by the different types of communities within which families reside and that community characteristics moderate the impact of family structure on drug use. The results of multilevel regression models fail to support these hypotheses; adolescents who reside in single‐parent or stepparent families are at heightened risk of drug use irrespective of community context. Moreover, adolescents who reside in single father families are at risk of both higher levels of use and increasing use over time. A significant community‐level effect involves jobless men: Adolescents are at increased risk of drug use if they reside in communities with a higher proportion of unemployed and out‐of‐workforce men.  相似文献

Child sexual abuse and adult sexual assault have been linked to increased self-blame, posttraumatic stress symptoms, and alcohol use. The current study aims to examine (a) whether these constructs explain women’s risk for later adult sexual assault and revictimization, (b) whether such factors differentially confer risk for specific types of adult sexual assault (i.e., substance-facilitated and forcible), and (c) if self-blame confers risk indirectly through other risk factors. Multiple types of self-blame, posttraumatic stress, and alcohol use were examined among 929 female college students as serial mediators of the relationship between child sexual abuse and adult sexual assault and as risk factors for sexual revictimization among child sexual abuse survivors. In the model predicting risk for substance-facilitated adult sexual assault, child sexual abuse indirectly predicted greater risk for substance-facilitated adult sexual assault mediated through two separate paths: global blame-to-posttraumatic-stress and global blame-to-alcohol use. In the model predicting risk for forcible adult sexual assault, child sexual abuse directly predicted greater risk for forcible adult sexual assault, and this relation was mediated by the global blame-to-posttraumatic-stress path. Among child sexual abuse survivors, child sexual abuse specific characterological and behavioral self-blame directly predicted greater risk for forcible and substance-facilitated revictimization, but the pathways were not mediated by posttraumatic stress or alcohol use. Results emphasize the importance of assessing different types of self-blame in predicting posttraumatic stress symptoms as well as examining risk for sexual victimization and revictimization. Findings did not support hypotheses that increased posttraumatic stress would predict increased alcohol use but did indicate that heightened self-blame is consistently associated with heightened posttraumatic stress and that heightened global self-blame predicts increased alcohol use. Implications for future research and intervention are discussed.  相似文献

The authors assessed the use of nonvitamin, nonmineral (NVNM) dietary supplements in a college population. They found that the use of NVNM dietary supplements among college students might be higher than that of other population groups and that the types of NVNM products they use differ from those used by an older population. Of the 272 students who completed the questionnaire, 48.5% reported they took an NVNM supplement during the past 12 months. The most frequently used NVNM products were echinacea, ginseng, and St John's wort. Of the 27 students who took NVNM products to promote weight loss, 81.5% had body mass index (BMI) values in the acceptable range. Eleven of the 19 participants who reported an adverse reaction to an NVNM supplement continued to take the products despite negative effects. Users and nonusers of NVNM supplements did not differ significantly by age, ethnicity, gender, perceived dietary adequacy, or by exercise patterns.  相似文献

The theory of organizations as “open systems” is used to develop hypotheses on the relationship between academic institutions and faculty teaching goals. The effects of three measures of academic organizations–type of control, institutional functions, and institutional affluence–on faculty support for four types of teaching goals are tested with data from a nationally representative sample of 301 academic institutions. Through the use of a path analytic model, it was found that these organizational characteristics directly affect the types of teaching goals faculty members endorse and the level of support for teaching goals in general.  相似文献

Attachment is an important predictor of relationship satisfaction and attachment insecurities are a risk factor for couples under stress. Drawing from the Vulnerability–Stress–Adaptation model, we investigated whether dyadic coping strategies (DCS) would explain the links between attachment insecurities and relationship satisfaction in 97 couples involved in medically assisted reproduction (MAR). Path analyses revealed that for women and men, attachment insecurities (anxiety, avoidance) were associated with their own lower relationship satisfaction through their lower use of positive DCS. Attachment avoidance was also associated with participants' own lower relationship satisfaction through their own lower use of negative DCS. Men's attachment avoidance was also related to their partner's lower relationship satisfaction via their own and their partner's lower use of positive DCS. The findings suggest that promoting the use of positive DCS may be important to preserve relationship satisfaction in couples involved in MAR.  相似文献

In a sample of 163 low‐income African American women, we used logistic regression analyses to test for associations between (a) 5 operationalized constructs theorized in the Sexual Health Model to impact one's overall sexual health (barriers to healthy sexuality, sexual anatomy and functioning, positive sexuality, sexual health care, and cultural identity) and (b) several measures of risky sexual behavior (consistent condom use, multiple concurrent partnerships, and overall sexual risk). No significant relationship was found between acculturation and risky sexual behaviors. Having sexual difficulties was positively associated with overall sexual risk and multiple concurrent partnerships. Favorable attitudes toward condoms were positively associated with consistent condom use. Desiring or intending pregnancy was positively associated with inconsistent condom use and overall sexual risk behavior. This is only the second study linking sexual difficulties and risky sexual behavior. The exact nature of this correlational relationship needs to be studied and replicated in different and more heterogeneous populations.  相似文献

This study explores the sexual risk trajectories of female youths and sheds light on the long-term effects of running away. It evaluates whether running away increases the risk of sexual assault in the following year, which is after runaways return home. The sample consists of 5,387 heterosexual females between the ages of 11 and 18 years from the Longitudinal Study of Adolescent Health. Nearly one quarter (23%) of runaways report a previous sexual assault in contrast to 5% of nonrunaways. In a logistic regression model, childhood neglect increases the risk of sexual assault between Waves 1 and 2 by nearly two times. Poor mental health is statistically significant. Alcohol use doubles the odds of sexual assault. The risk of sexual assault is approximately three-fold for girls with a history of sexual onset and sexual touching in a romantic relationship. Running away increases the risk by nearly two and a half times. There is evidence that alcohol use and sexual onset partially mediates the relationship between running away and sexual assault.  相似文献

Introduction.?This study was conducted to examine the relationship between dietary intake and the risk of chronic kidney disease (CKD), treated hyperuricemia (or gout) without CKD, and untreated hyperuricemia without CKD in elderly men.

Methods.?The study population comprised 752 men aged 65 or older who had been included in the Elderly Nutrition and Health Survey (1999–2000) (Elderly NAHSIT).

Results.?Statistical analysis using a polychotomous logistic regression model revealed that compared with the individuals in the normouricemic group, the individuals in the other groups exhibited a significant association between a higher prevalence of CKD and the following factors: advanced age, drug use for hypertension, egg and shellfish consumption and consumption of poultry with the skin and meat with fat. The significant risk factors for the patients who did not have CKD and were undergoing treatment for hyperuricemia were as follows: BMI?≥?25 kg/m2; drug use for hypertension; intake of poultry with skin; increased daily consumption of shellfish, fried food, sugar and juice.

Conclusions.?Men who use anti-hypertensive drugs and who consume fewer soy products and more shellfish may be at a higher risk of developing hyperuricemia or CKD.  相似文献

The benefits and negative consequences of government–nonprofit contracting are well documented. From the literature, we know that government and nonprofits can demonstrate contradictory organization-level characteristics. Some argue that these contradictions make government and nonprofits complementary partners, but empirical evidence reveals the potential loss of nonprofit voluntariness. How does one harvest the alleged benefits of the government–nonprofit relationship while minimizing the potential loss of nonprofit voluntariness? Through the qualitative investigation of one nonprofit, this study identifies seven types of organizational-level differences between the government and the nonprofit. These conflicts are manifested by three forms of power struggle. This illuminates that power struggles are the root cause of the potential loss of nonprofits’ voluntariness. The author argues that as long as nonprofits depend on the government for resources, power struggles will persist and voluntariness will be at risk; hence, addressing resource dependence is the key to answering our research question.  相似文献

Research has shown that protective actions are often used by rape victims, and some actions, namely, forceful physical resistance, are more effective in preventing a completed rape than other types of actions, such as nonforceful verbal resistance. The research is less clear, however, on the extent to which women who are victims of nonrape sexual victimization use protective measures and on the effectiveness of these actions. There is also uncertainty on the nature of the relationship between different types of protective actions, contextual characteristics, and the likelihood of completion of nonrape sexual victimization incidents. To investigate these issues, we used data from a national-level study of 4,446 female college students. Our results indicate that the use of protective action varied across type of sexual victimization and that the effectiveness of these actions on reducing the risk of a completed act is differentially related to type of sexual victimization. The findings suggest the need for sexual victimization prevention and education programs to include information regarding the efficacy of protective actions in both rape and nonrape incidents.  相似文献

ABSTRACT

Objectives: This study tests the following 3 hypotheses: (1) there is a direct association between consumption of sexually explicit media (SEM) depicting non-condom use and sexually transmitted infection (STI)-related sexual risk behavior among men who have sex with men (MSM); (2) the association between SEM consumption and STI-related sexual risk behavior is mediated by men's sexual self-esteem; and (3) the relationship between SEM consumption and sexual risk behavior is mediated by condom use self-efficacy. Methods: A cross-sectional, Internet-based survey on exposure to SEM and sexual behavior of 1,391 MSM in the United States was conducted in 2011. Results: The results confirmed Hypotheses 1 and 3, while Hypothesis 2 was rejected. Accordingly, a significant association between the use of SEM picturing condom use and STI-related sexual risk behavior among MSM was found. Likewise, we found that the association between the use of SEM and sexual risk behavior was mediated by condom use self-efficacy in an indirect path. However, SEM did not influence sexual risk behavior via sexual self-esteem. Conclusions: To promote STI prevention, the actors in SEM may be used as role models in managing condom use in sexual contexts.  相似文献

College students are a group at high risk of sexually transmitted infections due to inconsistent condom use and engaging in other risky sexual behaviors. This study examined whether condom use self-efficacy predicted the use of condom negotiation strategies (i.e., condom influence strategies) and whether condom influence strategies mediated the relationship between condom use self-efficacy and condom use within this population, as well as whether gender moderated the mediation model. Results showed a strong relationship between condom use self-efficacy and condom influence strategies. Additionally, condom influence strategies completely mediated the relationship between condom use self-efficacy and condom use. Although condom use self-efficacy was related to condom use, the ability to use condom negotiation strategies was the most important factor predicting condom use. The mediation model held across genders, except for the condom influence strategy withholding sex, where it was not significant for men. For women, condom use self-efficacy promoted the use of a very assertive negotiation strategy, withholding sex, and was consequently related to increased condom use. Overall, using assertive condom negotiation strategies (e.g., withholding sex and direct request) were found to be the most important aspects of increasing condom use for both women and men. Implications and suggestions for prevention programming are discussed.  相似文献

This study examined the impact of ethnic identity and neighborhood risk on drug and sex attitudes and refusal efficacy among early adolescent urban African American females (n = 175). The model also predicted a moderating relationship of ethnic identity on neighborhood risk for drug and sex attitudes and refusal efficacy. Data were collected as part of a larger drug education program and analyzed via hierarchical multiple regression. The analyses controlled for household structure and menarche. Results indicated a direct relationship of higher ethnic identity and higher sexual refusal efficacy, higher disapproval of drug use, and lowered intentions to use drugs. Neighborhood risk was directly related to lower disapproval of drug use. There was a small moderating effect of ethnic identity on neighborhood risk for intention to use drugs. Findings provide support for prevention programs for African American youth that seek to reduce risk behaviors by increasing ethnic identity, particularly in low resource communities.  相似文献

The relationship between family structure and marijuana use throughout adolescence was assessed among 1,069 African Americans from the NLSY. A model was also tested suggesting that the effects of family structure on marijuana use would be mediated by poverty, neighborhood quality, and adolescents' self‐control. As most prior studies have found, family structure was not related to female adolescents' marijuana use. For young men, being raised with both biological parents was associated with less marijuana use throughout adolescence compared to those whose mothers never married, divorced early and never remarried, or divorced and remarried. Some support for the model was also found. We concluded that being raised without the presence of a biological father is a risk factor for marijuana use among young men, but African American young women from single‐parent households have unique resources that protect them from marijuana use. Understanding those resources may offer insight into prevention programs for other youth.  相似文献

International standards highlight the steps required by risk assessment and involving first hazard identification, then risk evaluation and finally, if necessary, risk assessment. To check approach appropriateness to "risk evaluation" from manual patient handling through MAPO, a cross study was carried out in view of checking relationship between this new risk assessment model and occurrence of acute low back pain. After proper training the MAPO screening method was assessed in 31 wards, 411 exposed subjects of geriatric hospitals. At the same time health data were collected on occurrence of low back pain episodes during the last year both in the exposed subjects' group and the external reference group (n?237). Risk and clinical assessment data were tutored and checked by EPM research unit. The logistic analysis was used as a method to evaluate the relationship between risk index and acute low back pain. Investigating relationship between acute low back pain episodes and levels of MAPO screening index, carried out only with the people exposed who claimed to work for at least 30 hours per week (n = 178), showed definitely positive trends. The study results indicate that MAPO screening may represent a useful tool to estimate the risk from manual handling patients.  相似文献

Women's acceptance of the diaphragm: the role of relationship factors   总被引:1,自引:0,他引:1  
The vaginal diaphragm is a candidate for a female-controlled method of reducing risk of HIV/STI acquisition. We examined the association between relationship and partner factors and three measures of diaphragm acceptability: current use, consistency of use, and satisfaction with use. We conducted a telephone survey with 448 female members of a managed care organization, aged 18-49, who currently used contraception (including 140 diaphragm users, 187 pill users, and 121 male condom users). Use of a specific contraceptive was significantly associated with relationship length, condom-use negotiation self-efficacy, importance of covert use, perceived motivation of partner to prevent HIV/STIs, and perceived satisfaction of partner with current method. In addition, among diaphragm users, communication about HIV/STIs and perceived partner motivation to use a diaphragm were related to consistent use. These results suggest that acceptability of contraceptive methods among women is influenced by their perceptions of their male partner and relationship factors.  相似文献

ABSTRACT

The purpose of this study is to examine the use of various types of employee assistance promotional tools, including the types of promotion used and their relationship to program type (internal or external), program utilization, and promotional budget.

Our study suggests that a variety of tools are used by both internal and external EAPs. Employee and supervisor training is the most popular form of program promotion. Statistically significant relationships were found between program utilization rates and several types of promotional activities. Our research suggests that promotional materials affect EAP utilization rates, and consequently, the interaction between promotional activities and/or promotional materials and EAP utilization deserves additional research.  相似文献

Social network sites (SNS) have become increasingly pervasive in the daily lives of adolescents. This study explores the relationship between SNS use and perceived online social capital among adolescents using survey data from Australia and Korea. We conducted a face-to-face survey of adolescents (12–15-year-olds) in major cities in Australia (N?=?401) and Korea (N?=?644) in 2013. There was no significant difference in time spent on SNS between adolescents in the two countries; however, significant differences in the way adolescents use SNS were found. Australian adolescents tended to use SNS for group activities, whereas Koreans used it for social monitoring. There was a positive relationship between SNS use and online social capital in both countries. However, the types of social capital that were found to have a strong relationship to SNS use were different. Among Australian adolescents, SNS activities had a higher correlation with bonding social capital compared to bridging capital, whereas the result was contrasting among Korean adolescents. The impact of SNS use on online social capital differed between the two countries, showing that Australian adolescents reporting low SNS use gained online social capital if they used SNS more intensely. Finally, the impact of SNS use and culture on perceived online social capital was examined by conducting hierarchical multiple regressions. Interpersonal communication and group activities emerged as significant predictors of online social capital.  相似文献
