A large-scale mixed-mode experiment linked to the Dutch Crime Victimization Survey was conducted in 2011. The experiment consisted of two waves; one wave with random assignment to one of the modes web, paper, telephone and face-to-face, and one follow-up wave to the full sample with interviewer modes only.The objective of the experiment is to estimate total mode effects and more specifically the corresponding mode effect components arising from undercoverage, nonresponse and measurement.In this paper, mode-specific selection and measurement bias are defined, and estimators for the bias terms based on the experimental design are introduced and discussed. The proposed estimators are applied to a number of key survey variables from the Labour Force Survey and the Crime Victimization Survey.  相似文献

In a rank-order choice-based conjoint experiment, the respondent is asked to rank a number of alternatives of a number of choice sets. In this paper, we study the efficiency of those experiments and propose a D-optimality criterion for rank-order experiments to find designs yielding the most precise parameter estimators. For that purpose, an expression of the Fisher information matrix for the rank-ordered conditional logit model is derived which clearly shows how much additional information is provided by each extra ranking step. A simulation study shows that, besides the Bayesian D-optimal ranking design, the Bayesian D-optimal choice design is also an appropriate design for this type of experiments. Finally, it is shown that considerable improvements in estimation and prediction accuracy are obtained by including extra ranking steps in an experiment.  相似文献

This study examined the intervening role of empathy in the relations between identity styles (i.e., information‐oriented, normative, and diffuse‐avoidant styles), and inter‐personal behaviors (i.e., prosocial behavior, self‐ and other‐oriented helping, and physical and relational aggression). In a sample of 341 emerging adults, it was found that an information‐oriented style relates to a more adaptive pattern of interpersonal behaviors whereas a normative or a diffuse‐avoidant identity style relate to a more maladaptive pattern of interpersonal behaviors. Empathy played an intervening role between the information‐oriented style and interpersonal behavior, and between the diffuse‐avoidant style and interpersonal behavior. However, empathy did not intervene between the normative style and interpersonal behavior. Implications for future research are discussed.  相似文献

Based on a case study of three asymmetric new venture development (ANVD) alliances, we examine the governance of transitions from exploration to exploitation. We propose that role deficiencies, technological asymmetry, and the presence of a separate venture unit at established firms constitute important initial conditions influencing value realization in ANVD alliances. We further show that role-specific investments act as more appropriate mechanisms than contractual incentives to govern transitions from exploration to exploitation. Jointly, these findings provide new insights into the impact of structural and relational governance mechanisms on value creation in interfirm relationships.  相似文献

The sleep system (i.e. the combination of mattress and bed base) is an important factor of the sleep environment since it allows physical recuperation during sleep by providing proper body support. However, various factors influence the interaction between the human body and the sleep system. Contributing factors include body dimensions, distribution of body weight and stiffness of the sleep system across the mattress surface. During the past decade, the rise of several new bedding technologies has made it increasingly difficult for the consumer to select a proper sleep system. Therefore, this study presents a method to model human-bed interaction in order to objectively predict the ideal sleep system for a particular individual. The proposed method combines a personalized anthropometric model with standardized load-deflection characteristics of mattress and bed base. Results for lateral sleep positions show a root mean square deviation of 11.9 ± 6.1 mm between modeled spine shapes and validation shapes, derived from 3D surface scans of the back surface. The method showed to be a reliable tool to individually identify the sleep system providing superior support from a variety of possible mattress-bed base combinations.  相似文献

This study explores the relationship between tonal synchrony and maternal‐infant social engagement based on free‐play recordings of 15 mothers and their 3‐month‐old infants in a laboratory setting. Moment‐by‐moment analyses on a microlevel were used to study social engagement and vocal interaction. We analysed and categorized 854 vocalization periods (mother‐only vocalizations, tonal interaction periods, nontonal interaction periods, and mutual silence). Tonal synchrony was analysed in terms of harmonic and pentatonic series based on pitch frequency analyses. Social engagement was microanalyzed in terms of matched and mismatched engagement states. ANOVA‐repeated measures revealed, most importantly, a significant relationship between TIPs and social interaction repair, which indicates the importance of tonal synchrony in the flow of social engagement in mother–infant dyads. Other significant relationships were found between (a) nTIPs/mismatch–mismatch, and, (b) MOV/affect loss. As mentioned in the discussion, the findings are suggestive for clinical applications (e.g., music therapy) and warrant further research.  相似文献

Since 1994, policies have been instituted throughout the United States that require sex offenders to register their personal information with law enforcement officials (Jacob Wetterling Crimes against Children and Sexually Violent Offender Registration Program, 1994 Jacob Wetterling Crimes against Children and Sexually Violent Offender Registration Program. (1994). Cornell University Law School, Legal Information Institute: U.S. code collection. http://www.law. cornell.edu/uscode/42/usc_sec_42_00014071----000-.html (Accessed: 4 April 2008).  [Google Scholar]). With the passage of additional laws, this information is now available to the public via the Internet or a request to a police department. These laws have brought about consequences for both the registrants and for members of their families. A focus group was held with four mothers who have sons listed on the Michigan Sex Offender Registry. Psychological and social consequences of registration were found and policy implications are discussed.  相似文献
