A study of the correlation bias of unrecorded events by two independent enumeration systems

Summary In this paper the allegation that, when using the Chandrasekar-Deming technique with two independent enumeration systems to record the incidence of vital events and migrations, each individual system misses the same type of event is investigated. If this correlation bias were to occur frequently enough, it could result in a serious underestimation of a given type of event. Using vital events and migrations data derived from a longitudinal survey conducted in Liberia between 1969 and 1973, the estimated number of recorded events is tabulated into homogeneous groups that are demonstrated to affect omission rates. The proportion of missed eyents is computed separately for each enumeration system, and the presence or absence of a significant correlation mathematically determined. The results of this study suggest that no significant correlation could be demonstrated in the type of birth, death or infant death that was commonly missed by each individual enumeration system. This indicates that the omission of a birth, death or infant death was apparently a random occurrence as far as the individual casefinding systems were concerned. The authors conclude that any underestimation of vital events from this type of correlation bias may not be as serious as originally imagined. In contrast to this observation, the omission of particular types of migrations by each enumeration system was apparently not a random occurrence, but was associated with the direction of migration. This implies that selected migration rates in the liberian survey were probably understated and this could happen in other longitudinal surveys, unless specific precautions are taken to avoid it.     

论文明的发展趋势——生态文明

从属于地球共同体的人类文明走过了原始文明、农业文明,又演绎出今天的现代全球文明。现代文明的缺陷引起地球共同体终结的危机。因此人类文明需要进入新的发展过程,而走向生态文明就是人类和地球共同体的未来,这需要克服实证科学语言所具有的单一性,以东方占优势的类比思维来弥补西方实证科学逻辑思维的不足。无论是东方文明还是西方文明,都有着相互的关联。西方的逻辑、东方的关联和类比,都是走向生态文明的必须。     

Self‐Esteem Trajectories among Ethnic Minority Adolescents: A Growth Curve Analysis of the Patterns and Predictors of Change

The current study presents a growth curve analysis of self‐esteem among Black, Latino, and Asian American high school students. A series of hierarchical linear models were used to examine patterns and predictors of change in self‐esteem over time. Results revealed an average increase in self‐esteem with age. Although boys and girls experienced similar trajectories of self‐esteem, ethnicity was a significant moderator of developmental change. Black adolescents reported higher self‐esteem, while Asian American adolescents reported lower self‐esteem, compared with their Latino peers. Latino adolescents experienced a sharper increase in self‐esteem over time compared with Black adolescents. The unique and conjoint effects of adolescents' experiences with peers, family, and school were examined in relation to self‐esteem trajectories. Results revealed that each perceived context was significantly associated with self‐esteem trajectories when examined independently, but family experiences emerged as most strongly related to changes in self‐esteem. Results underscore the need to examine change at the individual level, as well as the importance of studying the unique and conjoint effects of individual and contextual‐level variables on developmental processes among ethnic minority adolescents.     

Eighteen Months Old in Dublin

SUMMARY: The data reported and discussed in this article are taken from the Dublin Child Development Study, a longitudinal study which started in 1985 with interviews of 200 women expecting their first child. Using information gathered in the first 18 months of the children's lives, an attempt is made to describe the sample of children as they arrive at the age of 18 months. The findings on the children's development are placed in the context of the study's information on their parents and in the wider social context in which the families lived, in Dublin in the late 1980s.     

‘Situative cognition’: barrier to teaching across cultures

In an unsettled world, the migration of significant numbers of individuals across national and even continental boundaries has changed the demographics of many nations with profound effects on their schools. Frequently, teachers are confronted with classes characterized by ethnic and cultural diversity for which they are either underprepared or totally unprepared. Despite their dedication, teachers have been shaped by their own cultural upbringing, and there may be a disconnect between their cultural values and identities and those of the children in their transformed classrooms. This disconnect has been called ‘situative cognition’. The challenge for teacher educators, particularly in western nations, is to enable prospective teachers to understand the complexity of educational dynamics in diverse classrooms, to examine their own experiences with diverse groups especially regarding culture, race, ethnicity and social class, and to develop strategies for working proactively with students in their own increasingly diverse communities.     

A competency approach to curriculum building: a social work mission

This article discusses The John A. Hartford Foundation CSWE SAGE-SW Project through an historical reflection of curriculum development within the profession. The project's relationship to several curriculum building models is also explored. A curriculum development tool for combining the Hartford Competencies with theCSWEEPAS requirements is provided.     

Teaching Note—BSW Students’ Experiences With an MBSR Assignment and the Five Facets of Mindfulness

BSW students appear to be under increasing levels of stress. In response to concerns about students’ well-being, we developed a three-credit-hour self-care elective. This article explores students’ participation in the primary assignment of the course, a modified version of mindfulness-based stress reduction. We also present empirical findings of an exploratory study examining students’ mindfulness and their subjective experiences with the assignment. Results support the usefulness of mindfulness-based stress reduction assignments in supporting BSW students’ well-being. This kind of assignment may also contribute to the development of the first social work competency, “demonstrate ethical and professional behavior,” (Council on Social Work Education, 2015, p. 7) through an increase in self-reflective and self-regulation skills.     

Social Policy and the Politics of Hispanic Aging

Abstract

This study examines the contributing factors to job satisfaction and commitment among lower-income, older (age 55 and over), part-time employees (N = 164). Job satisfaction index (JSI) scores were relatively high for all subjects and did not differ significantly for age, gender, or Senior Community Service Employment Program (SCSEP) status. While not particularly low, white employees were significantly less satisfied with their employment experiences than Hispanic or African American workers. The scarcity of fringe benefits was the least satisfying aspect of employment. Older Hispanics, whites, and men reported less interference between job, family, and home life than African Americans and women. Multiple regression analysis revealed that race/ethnicity, skill utilization opportunities, perceived views of elders held by younger workers and supervisors, availability of fringe benefits, and suitable work days explained the majority of variance in JSI scores. Opportunities to interact with others and stay active were more important than financial supplementation in these elders' assessment of the benefits of part-time employment. Findings provide further understanding of those elders likely to be placed successfully in part-time employment.
