Because of the inconsistency in the findings from past decades of research and the lack of consensus regarding the relationship between advertising exposure and cigarette consumption, the large body of extant research on the effectiveness of cigarette advertising has generated equivocal conclusions on this subject. Therefore, we conducted a comprehensive meta-analysis of cigarette advertising research to determine what impact, if any, cigarette advertising has on cigarette consumption. Unlike previous attempts to synthesize the cigarette advertising literature, this study examined three specific levels of the criterion (i.e., initiation, continuation, and brand behavior) rather than examining only aggregate consumption.  相似文献

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.  相似文献

The purpose of this article is to determine market orientation’s relative impact on small-business performance, compared to other influences, in an integrated model using longitudinal data. Contrary to expectations based on the management literature, the results indicate weak causal relationships between market environment, small-firm structure, and small-firm strategy. The results further indicate weak influences of these variables, but strong and consistent influences of market orientation, on various measures of small-firm performance. Contrary to expectations based on business policy literature, relative product quality and new product success were not significant influences on profitability, perhaps due to the significant influence of market orientation on these variables. In addition, although increases in growth/share had a significant short-term influence on increases in profitability, high levels of previous years’ firm growth/share had a negative influence on current profitability. The previous year’s level of firm coordinating systems and market competitive intensity has a significant impact on the level of small-firm market orientation.  相似文献

In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements.  相似文献

This paper discusses how instructors can engage their students in community-based participatory research (CBPR) projects that involve not only research on a topic but also include community stakeholders in the research process and provide opportunities for service learning. CBPR is defined, examples of effective CBPR student projects are presented, the possible benefits and drawbacks of CBPR student projects are offered, and tips for conducting successful CBPR projects with hospitality and tourism students are provided.  相似文献

The purpose of this study was to explore the roles of organizational politics in educational institutions with regard to graduate students’ satisfaction with supervision and loyalty toward advisors, and thereby success of students in the Ph.D. program, within the hospitality and tourism discipline. The findings demonstrate that satisfaction and loyalty play important roles in doctoral students’ experiences in graduate education. Several implications for students and faculty are discussed.  相似文献

Résumé Le retranchement, c'est-à-dire la réduction des ressources humaines, mate*** rielles et financières est devenu un problème familier dans plusieurs pays. L*** taux de chǒmage a augmenté de façon dramtique en Europe comme en Amer*** que du Nord, indiquant des redondances dans les secteurs public et privé ain*** que chez les cols bleus, les cols blancs et les cadres à la suite de conditior*** économiques défavorables, de coupures gouvernementales et de changemen*** technologiques. Les statistiques stériles cachent cependant un problème tri*** humain: celui des employés qui doivent accepter la perte involontaire de lei*** emploi. Plusieurs études parues récemment accentuent l'importance des b*** soins des employés lors des coupures. Les demandes peuvent cependant ět*** ignorées dans un climat de coupures lorsque les besoins de l'entreprise o*** précédence dans un effort de réduction des coǔts.*** Pour sensibiliser les employeurs aux besoins des employés, ils doivent ěti*** informés des avantages commerciaux associés à cette approche, alors que 1*** chercheurs doivent reconnaǐtre l'importance des préoccupations de l'emloyei*** en période de coupures. Cet article explore certaines des raisons économique*** justifiant l'intérět pour les préoccupations individuelles et présente un cadi*** destiné à aider les cadres à concevoir des stratégies de retranchement qui tiei*** nent compte à la fois des besoins de l'entreprise et de l'employé. Une etude c*** huit entreprises qui ont adopté une variété de programmes de coupures impl*** quant des employés de divers niveaux est discutée, démontrant comment *** cadre peut ětre appliqué  相似文献
