The effect of personalization on response rates and data quality in web surveys

Personalizing correspondence has often shown to significantly increase survey response rates in mail surveys. This study experimentally tests whether personalization of email invitations acts correspondingly to web survey response rates. Also, it is investigated whether personalization influences data quality. The results of the study, using a large student sample, show that personalization significantly increases the web survey response rate by 8.6 percentage points. The data quality does not appear to be affected in any major way by personalizing the email invitations. However, the analyses do show that respondents of the personalization condition tend to respond with more social desirability bias to sensitive questions. Therefore, it is concluded that personalization has positive effects on the survey response rate, but one should carefully consider whether or not to personalize when a survey on sensitive topics is conducted.     

The planning of cycle trips in the province of East Flanders

Traditional route planners assist in finding the shortest or fastest route from one place to another. This paper presents a novel approach to path finding in a directed graph, namely a target distance, motivated by the problem that a recreational cyclist deals with when searching a nice route of a certain length. The problem is defined as a variant of the arc orienteering problem (AOP), a new combinatorial optimisation problem in which the score of a route in a directed graph has to be maximised by visiting arcs, while each arc can be visited at most once and the total cost of the route should not exceed a predefined cost. The contribution of this paper is threefold: (1) a mathematical model of the AOP is provided, (2) a metaheuristic method that solves AOP instances to near optimality in 1 s of execution time, is proposed and evaluated, and (3) two real-life applications of the method are presented. An on-line cycle route planning application offers personalised cycle routes based on user preferences, and an SMS service provides cyclists “in the field” with routes on demand.     

Ignoring Leaders who Break Promises or Following God: How Depersonalization and Religious Faith Inform Employees’ Timely Work Efforts

This study investigates the relationship between employees’ perceptions of psychological contract breaches and their failure to meet work-related deadlines, with a particular focus on the mediating role of the depersonalization they assign to organizational authorities and the moderating role of their religious faith. Results based on multisource data, collected among employees and their supervisors in Pakistani organizations, show that an important factor that underpins the connection between beliefs about broken organizational promises and a diminished propensity to finish work on time is that employees depersonalize organizational leaders. This mediating effect is mitigated by employees’ religious faith. For organizations, this study thus identifies a key mechanism – exhibiting indifference to the people in charge – by which employees’ frustrations about resource-depleting contract breaches may inadvertently escalate into ineffective time management, and it identifies some workers among whom this counterproductive dynamic is less likely, namely, employees who can draw from their religious faith.
