I suggest an extension of the semiparametric transformation model that specifies a time-varying regression structure for the
transformation, and thus allows time-varying structure in the data. Special cases include a stratified version of the usual
semiparametric transformation model. The model can be thought of as specifying a first order Taylor expansion of a completely
flexible baseline. Large sample properties are derived and estimators of the asymptotic variances of the regression coefficients
are given. The method is illustrated by a worked example and a small simulation study. A goodness of fit procedure for testing
if the regression effects lead to a satisfactory fit is also suggested. 相似文献

In a recent paper, Pinto and Mabert [5] presented a lot-sizing rule and an improvement procedure for the joint lot-sizing problem with zero setup costs. We show that this procedure often yields infeasible schedules. We also present and discuss two interesting properties of the joint lot-sizing problem with zero setup costs. A numerical example to illustrate the second property is provided. 相似文献

The claim that multiple partner fertility may pose a risk of adverse outcomes for children has not been tested. We test this argument using a sample of 4,027 resident fathers and children from the Fragile Families and Child Well‐being Survey by examining the pathways through which fathers' multipartnered fertility is associated with children's externalizing behaviors and physical health status at 36 months. Path analyses indicate that multiple partner fertility exerted both a significant direct and indirect effect through paternal depression to influence children's externalizing behaviors. Fathers' multiple partner fertility also exerted a significant indirect effect through one mediator—father involvement—to influence children's physical health. This evidence suggests that the disruptions brought about by multipartnered fertility are important for understanding child well‐being. 相似文献

Frailty is a term often used by researchers and clinicians to describe a state in which older persons are at risk for adverse outcomes such as falls, disability, institutionalization and mortality. However, no study so far examined what frailty means to older persons. Therefore the aim of this study was to describe the meaning that older community-dwelling persons attach to frailty. Twenty-five semi-structured interviews were conducted. The interviews were analyzed using the grounded theory method. Frailty was described as being in poor health, having walking difficulties, feeling down, being anxious, having few social contacts and not being able to do the things one likes to do. Men described in more detail the physical dimension whereas women elaborated in more depth on the psychological and social component. Existing definitions of frailty should be adjusted to better reflect the meaning of frailty for older persons. 相似文献

This article discusses how women working as civil engineers within the UK construction industry perceive work–life balance and considers strategies they use to achieve this. The findings are presented of a qualitative research project that explored the experiences of women in this role, focusing on the subcultural context of a profession that is dominated by the values of presenteeism and infinite availability. A feminist post‐structuralist framework is used to analyse how women negotiate their personal and professional time and the extent to which their other roles as carers and nurturers unsettle male work practices in this highly gendered profession. There are gradually increasing numbers of women in professional construction roles and their success appears to depend on being able to fit in to the dominant masculine culture of long working hours and the male pub gathering. Despite an increased presence, women's minority status in construction continues to challenge their professional identity and this is central to the conflict many face between the dual roles of corporate worker and private non‐work person. 相似文献

Treating clients from diverse cultural backgrounds, and supervising clinicians who are treating clients of the same ethnicity
and gender, are now common experiences in our mental health system. As the growth of minorities in the US greatly outpaces
the training of minority clinicians, more attention to these situations is needed. Operating from the premise that interpersonal
sensitivity is a fundamental aspect of cross-cultural and cross-ethnic sensitivity, we describe the treatment of a Latino
male by a Latino male clinician, in this case both of Puerto Rican descent. We outline the contours of the therapy with a
man whose life history included numerous incidents of humiliation and thwarted efforts at efficacy, mastery, agency, and competence,
resulting in an adult character structure based on shame and self-doubt. We also discuss the challenges to the clinician posed
by working with a man whose traditional upbringing mirrored his own, with all the positives and negatives that must be considered
in the countertransference. We describe clinical and cultural reasons for various interventions, and their resulting outcome.
The framework of a dynamic interpersonal therapy and the challenges of transference, countertransference, therapist disclosure,
and working-through are covered. 相似文献

This study examines changes over time in ethnic affirmation/belonging and ethnic identity achievement, Spanish language use, English language use, Mexican/Mexican‐American affiliation/identification and Anglo affiliation/identification in a sample of Mexican‐American adolescents participating in a longitudinal study of juvenile offenders. The Multigroup Ethnic Identity Measure and the Acculturation Rating Scale for Mexican Americans‐II were completed by the Mexican‐American adolescents 7 times over a 3‐year period. The findings from longitudinal growth modeling analyses and growth mixture modeling analyses indicate that there is heterogeneity in the initial scores and changes over time on these variables that are related to markers for the cultural qualities of the home environment (i.e., generational status and mother's most frequent language use). In contrast to expectations, marginalized or assimilated acculturation trajectories/types were not overrepresented in this sample of adolescent offenders. Implications for our understanding of the nature of acculturation and enculturation processes and the way these processes are studied are discussed. 相似文献

This study examined the longitudinal associations among maternal warmth, adolescents' self‐disclosure, and maternal knowledge during the transition to adolescence. Three years of self‐report data were collected from 131 married mothers and their adolescents. Results from longitudinal analysis using adolescent reports indicated that greater maternal warmth in sixth grade predicted higher levels of adolescents' self‐disclosure in seventh grade, which in turn led to higher levels of maternal knowledge in eighth grade. Thus, adolescents' self‐disclosure served as an indirect link between higher maternal warmth and greater knowledge over time. An alternative model with prior self‐disclosure predicting subsequent maternal warmth and knowledge was not supported. Overall, this study demonstrated a time‐ordered process by which maternal warmth and adolescents' self‐disclosure predict maternal knowledge. Understanding such processes that affect parental knowledge may be beneficial for future prevention and intervention efforts during the transition to adolescence. 相似文献

In this article we examine the encounter between global human rights ideas and domestic discourses of civil rights and social justice, focusing on processes of translation and adaptation of women's human rights in two ethnographic sites in New York City. The first site is a citywide coalition working for the adoption of a New York City human rights ordinance. The second site is an advocacy organization working on domestic violence issues. We find that the local adoption of human rights in New York City – the ‘domestication’ of human rights – takes place in two central sites: law and social movement. We further find that the process of translation takes place unevenly in the two sites, and it is driven primarily by the actors, mechanisms and technologies in the social movement arena. Overall, we witness the emergence of a domestic human rights movement as a new counter‐hegemonic space, characterized by multiplicity in meanings, ideological heterogeneity and ambivalence from those engaged in its construction. 相似文献
