The linear transformation model is a semiparametric model which contains the Cox proportional hazards model and the proportional odds model as special cases. Cai et al. (Biometrika 87:867-878, 2000) have proposed an inference procedure for the linear transformation model with correlated censored observations. In this article, we develop formal and graphical model checking techniques for the linear transformation models based on cumulative sums of martingale-type residuals. The proposed method is illustrated with a clinical trial data. 相似文献

当今日本大学的各种设施、设备之完备令人惊叹,但大学生学习能力低下、求知欲减退、读书量减少等问题越来越引起人们的关注。大学如果没有各种设施设备的话,其教育机能是无法实现的;但如果这些手段不与学习、教育机能相结合,未被用于提高教师的教学努力和学生的学习欲望,也就无法达成大学作为教育机关的目的。设施、设备等硬件只有有了软件的支持才能产生效果。 相似文献

Happiness and Satisfaction with Work Commute 总被引:1,自引:0,他引:1

Research suggests that for many people happiness is being able to make the routines of everyday life work, such that positive feelings dominate over negative feelings resulting from daily hassles. In line with this, a survey of work commuters in the three largest urban areas of Sweden show that satisfaction with the work commute contributes to overall happiness. It is also found that feelings during the commutes are predominantly positive or neutral. Possible explanatory factors include desirable physical exercise from walking and biking, as well as that short commutes provide a buffer between the work and private spheres. For longer work commutes, social and entertainment activities either increase positive affects or counteract stress and boredom. Satisfaction with being employed in a recession may also spill over to positive experiences of work commutes. 相似文献

This paper uses a non-standard value assumption—uncertainty reduction—to explain parenthood. We begin by reviewing the inadequacies of normative and standard rational choice explanations of shifts in fertility behavior. Then we propose a theory of the value of children based on the uncertainty-reduction assumption. Next we generate a range of hypotheses that follow both from this assumption and from a subsidiary assumption of marital solidarity enhancement. Finally, we explore the extent to which implications based on these new ideas are supported by the relevant empirical literature. 相似文献

This study examined the developmental course of infants' attentional preferences for 3 types of infant‐directed affective intent, which have been shown to be commonly used at particular ages in the first year of life. Specifically, Kitamura and Burnham (2003) found mothers' tone of voice in infant‐directed speech is most comforting between birth and 3 months, most approving at 6 months, and most directive at 9 months. Thus, the aim of this study was to assess whether there is a relation between the type of affective intent used by mothers at each age point, and infants' affective intent preferences. Each infant group, 3‐, 6‐, and 9‐month‐olds, was played the 3 types of affective intent alternating across a single test session. When analyzed across age, the interactions revealed the predicted developmental trajectory; that is, infant preferences transformed between 3 and 6 months from comforting to approving, and between 6 and 9 months, from approving to directive. However, when analyzed separately by age, it was shown that 3‐month‐olds preferred comforting to other types; 6‐month‐olds preferred approving to directive, but listened equally to approving and comforting; and 9‐month‐olds showed no preference for any type of affective intent. Because it was possible that 9‐month‐olds were more focused on phonetic and phonotactic information, a new group of 9‐month‐olds was tested with intonation‐only versions of the 3 affective intent types. Under these conditions, they were found to prefer directive to comforting, but not directive to approving types. The results of this study have implications for what infants pay attention to in their social and linguistic environment over the course of the first year. 相似文献

Using survey data collected by the Japan Institute of Life Insurance in 2002, this study finds that a significant gender gap existed in defined contribution (DC) pension knowledge among workers employed at small- to medium-sized private firms in Japan. Even with similar DC knowledge, however, men and women reveal different preferences for DC pensions, indicating that their perceptional responses may widely differ from actual behaviors. Apart from the knowledge gap, the result shows evidence of the Prince Charming Syndrome among female employees as a significant source of the gender gap in DC participation rates. Among corporate pension-covered employees, the gender difference in the efficacy of DC portability is a more significant gap-generating factor. DC tax advantage is particularly favored by pension-covered female employees over male counterparts, reducing the DC preference gap. No similar evidence is found for employees with no corporate pension coverage. 相似文献

Disparities in children's early language skills associated with socioeconomic factors have led to many studies examining children's early language environments, but few as yet in the first year of life. This longitudinal study assessed the home language environments of 50 Australian infants, who varied in maternal education (university education, or not). Full‐day audio recordings were collected and analyzed using the LENA system when infants were aged 6–9 months and 12–15 months. Using the device‐specific analysis software, we assessed 12‐h projected counts of (1) adult speech input, (2) conversational interactions, and (3) child vocalizations. At both ages, higher maternal education was associated with higher counts of adult words and conversational turns, but not child vocalizations. The study adds to the literature by demonstrating disparities in the infants’ language experience within the first year of life, related to mothers’ education, with implications for early intervention and parenting supports. 相似文献

The purpose of this study was to clarify the relationship between collective efficacy and contextual performance among university athletes in Japan. We carried out 305 university athletes (201 males, 104 females) from 14 teams in various geographic areas in Japan. The average age of the participants was 19.91 years (SD = 1.01). The kinds of sports were soccer, basketball, baseball, volleyball, and so on. Then, using Collective Efficacy Questionnaire for Sports (CEQS; Sandra E. Short et al., 2005) and Contextual Performance Scale (Ikeda, and Furukawa, 2008), we examined the relationship between collective efficacy and Contextual performance. In conclusion, this study provided the following three remarks. 1) There are relationship between collective efficacy and contextual performance. 2) Contextual performance execution level improve collective efficacy. 3) It is important to always recommend contextual performance in own team to strengthen the collective efficacy more. 相似文献

Because tuition payment comprises a large proportion of expenses in households with children in universities, it causes large and clearly predictable changes in discretionary income in predetermined months. This study examines consumption smoothing for those households as an alternative test of the life-cycle/permanent income hypothesis, using the Japanese Family Income and Expenditure Survey. We show that a one yen decrease in discretionary income due to tuition payment is associated with 0.1–0.2 yen decrease in non-tuition spending in the month of tuition payment, showing that those households are not engaged in consumption smoothing. 相似文献
