Exploring the Impact of Cultural Value Orientations on Market Mavenism and Opinion Leadership

Market mavens and opinion leaders are two key types of consumer influentials. The focus of this research is to extend their predictor characteristics by drawing on the four-way horizontal and vertical individualism-collectivism typology. The theoretical and practical contributions of this study are established by the findings based on the survey data collected from 313 online consumer panelists in the United States. Market mavenism and opinion leadership were independent yet moderately related concepts. Vertical individualism and horizontal collectivism were significant predictors of both market mavenism and opinion leadership while horizontal individualism affected only market mavenism. Vertical collectivism did not predict either type of consumer influentials. Interaction with service employees moderated the relationships between horizontal collectivism and market mavenism and between vertical individualism and opinion leadership.     

Keeping our children safe in motor vehicles: knowledge,attitudes and practice among parents in Kuwait regarding child car safety

Child safety restraints can reduce risk of death and decrease injury severity from road traffic crashes; however, knowledge about restraints and their use in Kuwait is limited. A cross-sectional, self-administered survey about child car safety was used among a convenience sample of parents of children aged 18 years or younger at five Kuwaiti university campuses. Of 552 respondents, over 44% have seated a child in the front seat and 41.5% have seated a child in their lap while driving. Few parents are aware of and fewer report using the appropriate child restraint; e.g., 36% of parents of infants recognised an infant seat and 26% reported using one. Over 70% reported wearing seat belts either “all of the time” (33%) or “most of the time” (41%). This new information about parents' knowledge and practice regarding child car seat use in Kuwait can inform interventions to prevent child occupant injury and death.

A Framework for Reconsidering the Lake Wobegon Effect

The Lake Wobegon Effect (LWE) describes the potential measurement-error bias introduced into survey-based analyses of education issues. Although this effect potentially applies to any student-report variable, the systematic overreporting of academic achievements such as grade point average is often of preeminent concern. This concern can be easily circumvented if official records data are available; however, many researchers can only access student-reported data. In this article, the authors examine whether using student-survey data in place of official records data meaningfully biases regression estimates. They motivate their contribution by noting a useful statistical feature of overreporting on bounded variables such as grade point average. Specifically, the misreports will be negatively correlated with the true grade point average, yielding a form of nonclassical measurement error that actually counteracts the bias. The authors connect this observation to reliability ratios used in labor economics, which are simple ways to adjust for attenuation bias, when needed. In two applications, we find that it is unnecessary to correct for the LWE bias because it is so small.     

Time Series Analysis of Repeated Surveys: The State–space Approach

Cross sectional estimates from repeated surveys form a time series { y_t }. These estimates can be viewed as the sum y _t = Y _t + e _t of two processes, { Y _t }, the population process and { e _t }, the survey error process. Serial correlations in the latter series are usually present, mainly due to sample overlap. Other sources of data such as censuses, administrative records and demographic population counts are also available. The state–space modelling approach to the analysis of repeated surveys allows combining information from different sources, incorporating benchmarking constraints in a natural way. Results from these methods seem to compare favourably with those from X-11-ARIMA in filtering out survey errors.
