This study used the Information Motivation Behavioral (IMB) skills model to examine condom use among rural youth in Edo State, Nigeria. Data were collected from 4,801 youth aged 11 to 17 years attending Junior Secondary Schools. Analysis focused on 1,749 (Male = 1,134, Female = 615) sexually active youth. Random-effects ordinal logit models were used to examine the effects of the various components of the IMB framework on frequency of condom use. Gender-specific models were estimated. Results provided qualified support for the IMB. Specifically, youth who communicated with teachers and peers about condoms and HIV had higher odds of saying they used condoms always than sometimes or never. Compared to males who did not think they could get HIV, those who thought they probably could get infected were less likely to use condoms frequently. Similarly, compared to those who didn’t, females who knew others infected with HIV were less likely to use condoms frequently.

Purpose The purpose of this paper is to analyze how family ownership influences the strength of the board’s monitoring function in companies’ decisions regarding the assurance of sustainability reports. Design/methodology/approach The international sample consists of 536 companies operating in more stakeholder-oriented countries during the period 2007-2014. The paper proposes alternative logit models of analysis using the random-effects estimator. Findings The results provide evidence that a firm’s sustainability assurance and its choice of accounting professionals as higher quality assurers are positively associated with board size and independence. The main result is the positive impact of family businesses on these assurance issues. The paper evidences the greater orientation toward sustainability issues of family businesses. Furthermore, it verifies the greater impact of board size on family firms’ assurance demand. Originality/value This study sheds some light on the unexplored topic of sustainability assurance in family firms. One of the differentiating aspects with respect to previous studies is the consideration of the moderating factor of family property. This study also contributes to the understanding of family firms’ demand for assurance and its practitioners, and the literature’s focus on its determinants.

Brand Preferences

In analyzing panel data, the issue of heterogeneity across households is an important consideration. If heterogeneity is present but is ignored in the analysis, it will result in biased and inconsistent estimates of the effects of marketing mix variables on brand choice. The authors propose the use of a random effects specification to account for heterogeneity in brand preferences across households in a logit framework. The model parameters are estimated by both parametric and semiparametric approaches. The authors also compare their results with those obtained from logit models in which observed past choice behavioir is used to capture such heterogeneity. The different models are estimated with the IRI saltine crackers dataset. A formal statistical test of the model specifications shows that the semiparametric specification is the most preferred in terms of the overall fit of the model to the data. In addition, that specification predicts best when the models are validated in a holdout sample of households.

AbstractThis paper examines the effect of corporate governance mechanisms on companies’ decision to assure their sustainability reports and their choice of assurance provider in countries with a greater stakeholder orientation. The corporate governance factors analyzed are related to the strength of the board’s monitoring function, which is determined by the size, independence and activity of the sustainability committee. The international sample consists of 610 companies operating in countries that are more stakeholder oriented from the period 2007–2014. We propose alternative logit models of analysis using the random effects estimator. Consistently with our propositions, our results provide evidence that a firm’s sustainability assurance and its choice of the accounting profession are positively associated with board independence and the activity of the sustainability committee. In addition, the empirical evidence obtained shows a U-shaped relationship between the board size and assurance issues.
