This longitudinal study explores the relationship of postpartum depression (PPD) and marital dysfunction on infant outcomes from birth to 2 1/2 years of age among middle-class, postpartum women. Participants were recruited during the prenatal period. Twelve mothers completed the study throughout a 2 1/2-year period. Questionnaires, semistructured interviews, and observations were used to collect data. Content analysis of the interviews (Morse & Field, 1995) was conducted and thematic patterns were identified. Clinical PPD and marital dysfunction (defined as little or no support or closeness, or verbal, emotional or physical abuse) characterized nearly one in three mothers. Four themes describing the women's postpartum progression were identified: stress, isolation, resentment, and eventual adjustment by creating a new normal. No major developmental delays or behavioral problems were found among the infants. Eight of the 12 mothers who were initially identified as breastfeeding nursed their infants for 6-18 months. Regardless of financial and educational advantages, mothers in the study experienced depression and marital dysfunction. These findings support other studies that confirm the lack of association of PPD with social class or marital status. Childbirth educators and other health care professionals are encouraged to continue providing expectant families with anticipatory education and community resources in order to increase awareness of mental health and marital risks during the postpartum transition.  相似文献

A major objective of current life course research is to specify the processes linking early childhood conditions to subsequent life course statuses that span educational, occupational, familial, and health domains across the life span. This study confronts at least two persistent challenges to the rigorous specification of the relationships among these variables. The first is that the point-in-time measurement of education as “years of schooling” masks considerable heterogeneity in the timing and curricular tracks of schooling and obscures our understanding of how and when education matters for life-course inequality. The second challenge involves interdependencies between aspects of life-course inequality, including educational achievement and health. The intertwining of these variables across the life course, and their usual conceptualization and measurement, limit the interpretation of their relationship and its generalizability across studies. We use data from three waves of the National Survey of Families and Households between 1987–1988 and 2001–2002 to explore trajectories of self-reported health, applying latent class cluster analysis (finite mixture models) to deal directly with these measurement and specification issues. Generally, we find mediating effects of education in mid- to late-life health demonstrating the pivotal role of education in life course processes. Women’s childhood backgrounds are more heterogeneous and temporally complex educational careers affect their self-assessed health more than men’s. Late degrees are linked to poor health trajectories among women, but not men. Also, marital history, number of births and health behaviors are associated in expected ways with women’s and men’s health trajectories at midlife.  相似文献

This study reported how ten Taiwanese Master’s students perceived their experiences of receiving feedback given by their peers and writing consultants to revise a shortened version of their thesis proposals. Collected over the course of one semester, data included students’ writing portfolios and interviews with them. Analysis of the data revealed three major themes: (1) The participants felt quite positive about providing and receiving peer feedback, although they seemed cautious toward language-related peer comments; (2) they generally had positive experience with the writing consultants, although the perceived usefulness of the consultants’ feedback varied with individual consultants and (3) the two types of comments served different functions for students, and questions arose from the peer editing process could serve as prompts for writing consultation sessions. Possible future research directions as well as pedagogical implication are outlined to conclude the paper.  相似文献

National longitudinal databases hold much promise for school counseling researchers. Several of the more frequently used data sets, possible professional implications, and strategies for acquiring training in the use of large‐scale national data sets are described. A 6‐step process for conducting research with the data sets is explicated: determining research questions, accessing the data set, understanding the study's sample design, determining an analytic sample, considering pertinent data analysis issues, and understanding the limitations of using the data sets. Suggestions for preparing school counseling researchers and potential themes for future research are outlined.  相似文献

Practicums, internships and field experiences are essential components in many fields. These varied experiences embed both students and their mentors in immersive experiences. Such immersive experiences are essential for STEM students preparing for future jobs, yet little is known about how these research-intensive and immersive experiences impact the practice of teaching in the natural sciences. In order to evaluate the impact, opportunities and challenges associated with such experiences, our team collected and analysed end-of-semester reflections from five students and their faculty mentor. Thematic analysis related to inferences and implications about the impacts of the experience showed a need to formalize and further develop an understanding of both students’ self-identity and the cultural attitudes of the students and the mentor.  相似文献

Abstract

The purpose of the present study was to determine velocity discrimination characteristics of subjects in a difference threshold paradigm. After recruitment, 180 male and female subjects were randomly assigned to 1 of 6 groups differentiated by the length of the stimulus runway and the subjects' orientation to the stimulus. Stimulus velocities were presented on a modified Bassin Anticipation Timer with presentation rate controlled by a programmed timer. The criterion velocities were 134.11, 268.22 and 402.33, cm/sec with variable velocities ranging 44.7 cm/sec above and below the criterion in 8.94 cm/sec increments. The method of constant stimuli was used with 198 trial pairs presented (constant 7 second stimulus presentation interval). The results indicated that the discrimination of horizontal linear velocity follows a prothetic continuum. That is, the just noticeable difference increased in proportion to the increase in the criterion velocity. In addition, the subjects' orientation to the stimulus and the viewing distance (length of runway) seemed to play little or no role in the discrimination process.  相似文献

Anchored in the narrative inquiry tradition, this paper examines commonly held motives about curriculum making from the perspectives of four experienced physical education teachers in Korea. Field texts were collected throughout by employing narrative research tools such as in-depth interviews, focus groups, class observations and documents analyses, and transformed into research texts using broadening, burrowing, and storying and restorying as suggested by Connelly and Clandinin. For experienced physical educators, this paper illuminates what motivates curriculum making as a narrative phenomenon storied and restoried over time. Different stories produced different motives of curriculum making, and a number of issues related to teacher development for curriculum making emerged.  相似文献

Two Web-based breastfeeding programs were developed to provide new parents with necessary information on proper breastfeeding techniques. One version was plain text and the other version combined text with graphics. The computer was viewed as a valuable learning tool. The breastfeeding program that contained graphics was preferred over the text-only program. Educators are encouraged to use Web-based graphic programs to provide breastfeeding education to new parents.  相似文献
