Rates of missing responses in personal digital assistant (PDA) versus paper assessments 总被引:1,自引:0,他引:1
This article describes rates of missing item responses in personal digital assistant (PDA) assessments as compared to paper assessments. Data come from the evaluation of a classroom-based leisure, life skills, and sexuality education program delivered to high school students in Cape Town, South Africa. Analyses show that the paper assessments had much higher rates of missing-ness than PDA assessments. This association is moderated by item order. Certain analyses also suggest that paper assessments have higher rates of missingness for items pertaining to participants' sexual behavior. Implications of these results for evaluation research will be discussed. 相似文献

This research attempts a more contextualized approach to examining organizational citizenship behavior (OCB). Borrowing from theory in international and cross cultural management as well as organizational behavior, context is conceptualized as multi-level and as a shaper of meaning and variability in employee citizenship behaviors. By centralizing the unique socio-cultural, political and historical national context (i.e., omnibus context) of Lebanon at the core of our theorizing, we hypothesize, contrary to previous research, a positive relationship between idiocentrism and employee engagement in organizational citizenship behaviors. Furthermore, we explore the influence that unit level OCB (i.e., discrete context) has on the idiocentrism–OCB relationship. Our analysis confirms the positive relationship between idiocentrism and OCB in this unique context. In addition, our cross-level analysis suggests that in workgroups with higher levels of unit level OCB, idiocentrism is more strongly related to employee engagement in OCB. The findings highlight the value added in contextualizing research on OCB and employee behavior in general. 相似文献

The recent and prolific attention to public sociology has involved a great deal of theoretical debate about its merits, flaws,
and potential future within the discipline. Despite the loud call for becoming more public, existing research on the discipline
lacks both an empirical understanding of where we are as well as a methodological rubric to guide future inquiry. This project explores one outlet for public sociology—the press—as
a starting point for this line of research. Through an investigation of Associated Press stories featuring sociology and sociologists,
we seek to provide a baseline for consideration of public sociology efforts by describing the current state of how our discipline
and its members are portrayed in the press. Further, based on our findings we provide some insights for future research. 相似文献

The attainment of self‐regulatory skills during the toddler years is an understudied issue, especially among low‐income children. The present study used growth modeling to examine the change over time and the final status in children's abilities to self‐regulate, in a sample of 2,441 low‐income children aged 14 to 36 months. Positive growth in their self‐regulation occurred between 14 and 36 months, but individual variation was observed in both the growth rates and final status. Children who showed high degrees of negativity at 14, 24 and 36 months grew at slower rates than other children. Boys and children high in negativity had lower scores in self‐regulation at 36 months than girls and children with low negativity, whereas higher quality mother–child interactions at 14 and 24 months were associated with better self‐regulation at 36 months. The results suggest that some children may be at risk for developing problems in regulation because of mother–child interaction patterns and child characteristics such as high negativity. 相似文献

Consider semi-competing risks data (two times to concurrent events are studied but only one of them is right-censored by the other one) where the link between the times Y and C to non-terminal and terminal events, respectively, is modeled by a family of Archimedean copulas. Moreover, both Y and C are submitted to an independent right censoring variable D. We propose to estimate the parameter of the copula and some resulting survival functions using a pseudo maximum likelihood approach. The main advantage of this procedure is that it extends to multidimensional parameters copulas. We perform simulations to study the behavior of our estimation procedure and its impact on other related estimators and we apply our method to real data coming from a study on the Hodgkin disease. 相似文献

Many follow-up studies involve categorical data measured on the same individual at different times. Frequently, some of the individuals are missing one or more of the measurements. This results in a contingency table with both fully and partially cross-classified data. Two models can be used to analyze data of this type: (i) The multiple-sample model, in which all the study subjects with the same configuration of missing observations are considered a separate sample. (ii) The single-sample model, which assumes that the missing observations are the result of a mechanism causing subjects to lose the informtion from one or some of the measurements. In this work we compare the two approaches and show that under certain conditions, the two models yield the same maximum likelihood estimates of the cell probabilities in the underlying contingency table. 相似文献

This study looks at how households cope financially with a budget under a certain financial strain (after the birth of a new baby), and particularly examines their financial management practices and debting behaviour. Other factors associated with debt status caused by financial strain — particularly psychological variables — are also examined. A number of indexes were calculated from questionnaire data and used to measure these variables. The results showed that being in debt was significantly associated with feelings of coping less well and with better financial management. Better coping was also significantly associated with being more ‘forwardlooking’ and having a more negative attitude towards debt. Better financial strategies were significantly associated with being less materialistic and having a more stable budget. The results confirm previous findings that psychological and behavioural variables have a considerable impact on being in or keeping out of debt, but also suggest that perceived poor coping and being in debt during a period of particular financial strain may actually lead to an improvement in financial management. 相似文献

E-mail: cdavis3eutk.edu Summary The purpose of this study was to explore the relationship offamily, peer and school factors on the mental health of Chinesemale and female at risk adolescents and secondary school studentsin Hong Kong. Questionnaire surveys based on various standardizedassessment scales were conducted with 398 (183 female and 215male) Chinese at risk adolescents and 320 (160 female and 160male) Chinese secondary school students between 12 and 18 yearsof age in Hong Kong. Compared to secondary school students,at risk adolescents had poorer relations with parents, morenegative family and peer influence, a more negative school environment,and poorer social functioning. Findings also revealed that femaleparticipants had more somatic symptoms, anxiety, and depressioncompared to males. The importance of environmental factors onthe mental health of Chinese adolescents supports previous researchin Western countries. Implications for intervention and preventionwere discussed from a cross-cultural perspective. 相似文献
