This study has three goals: (1) to provide an extensive review of research on the assets/expectation relationship, (2) to provide a conceptual framework for how children's savings effects children's college-bound identity (children's college expectations are a proxy for children's college-bound identity), and (3) to conduct a simultaneous test of whether owning a savings account leads to college-bound identity or college-bound identity lead to owning a savings account using path analytic technique with Structural Equation Modeling (SEM). Our review reveals asset researchers theorize about college-bound identity in two distinct but compatible ways: college-bound identity as a “linking mechanism”, and college-bound identity as a mediator. However, there has been little theoretical development on the attitudinal effects of assets. In this study, we posit a conceptual framework for how children's savings affects children's college-bound identity. Findings from the simultaneous test of the assets/college-bound identity relationship suggest that savings has modest effect on college-bound identity and vice versa. A policy implication is that asset building policies that seek to build children's college-bound identity in addition to their savings may be more effective than policies that only seek to build children's savings. 相似文献

Social skills training and parent education programs for aggressive preschoolers and their parents in South Korea 总被引:1,自引:0,他引:1

The purpose of this study was to develop and evaluate social skills training and parent education programs for aggressive young children and their parents in South Korea. Participants consisted of intervention group I, which included six children and their mothers in the social skills training and parent education programs; intervention group II, which included seven children and their mothers in the social skills training; and control group, which consisted of six children and their mothers. Pre-test-post-test control group design was used. Participants in both intervention groups reported a significant decrease in aggression and on improvement in pro-social behavior, emotional regulation, and social skills, while the control group reported an increase in aggressive behavior. Mothers in the intervention group I also reported an increase in warmth/acceptance. The findings indicate that both programs are highly effective in reducing aggressive behavior among young children and in fostering positive parenting behaviors. 相似文献

The purpose of this study was to develop a Korean College Stress Inventory (KCSI), which is designed to measure Korean college students' experiences and symptoms of career stress. Even though there have been numerous scales related to career issues, few scales measure the career stress construct and its dimensions. Factor structure, internal consistency, and concurrent validity of the KCSI scores are described. Results indicated that the internal consistency reliabilities of 4 KCSI subscale scores were reasonably high. In addition, the exploratory and confirmatory factor analyses indicated that the modified 4‐factor solution seemed to provide a reasonably good fit to the data. Implications, limitations, and recommendations for future research are discussed. 相似文献

We consider a two-stage flexible flow shop problem with a single machine at one stage and m identical machines at the other stage, where the processing times of each job at both stages are identical. The objective is to minimize the makespan. We describe some optimality conditions and show that the problem is NP-hard when m is fixed. Finally, we present an approximation algorithm that has a worst-case performance ratio of $\frac{5}{4}$ for m=2 and $\frac{\sqrt{1+m^{2}}+1+m}{2m}$ for m≥3. 相似文献

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism. 相似文献

Despite great overall improvement in the elderly's economic status over the past two decades, minority elders still comprise the poorest population group of all. Nonetheless, the income security of minority elders has not been given special attention in the scrutiny in recent years of the size and the future of various federal programs affecting older persons. Based on data from the 1971, 1981, and 1991 public-use data tapes of the Current Population Survey, the racial difference in income status of the elderly and the role of Social Security and Supplemental Security income versus that of income from private sources are analyzed in terms of how income inequality among races is ameliorated or escalated. The findings show that racial/ethnic differences in income status increased between 1970 and 1990. The findings also confirm that, for both elderly singles and couples, Social Security is the most important income source. Without it, poverty rates among elderly black couples, for example, would have increased by as much as 48.5 percentage points in 1990. Policies that would help improve the income status of the low-income elderly are discussed. 相似文献

ABSTRACT The proliferation of technology has been changing feedback delivery methods in organizations. However, the effectiveness of feedback delivery methods can vary depending on social dynamics (e.g., authority relations) in the organization. The current study was designed to examine the impact of authority relations and feedback delivery methods on performance. A total of 120 participants were recruited to work on a simulated cell-phone assembly task and were exposed to one of the four feedback conditions: (a) authority figure with face-to-face feedback, (b) authority figure with e-mail feedback, (c) non-authority figure with face-to-face feedback, and (d) non-authority figure with e-mail feedback. Results showed that while both feedback delivery methods resulted in high performance with the presence of an authority figure, only face-to-face feedback resulted in high performance with a non-authority figure. Practical considerations for effective feedback delivery methods in relation to authority figures are also discussed. 相似文献

Using a unique data set of causal usage drawn from research articles published between 2006–2008 in the American Journal of Sociology and American Sociological Review, this article offers an empirical assessment of causality in American sociology. Testing various aspects of what we consider the conventional wisdom on causality in the discipline, we find that (1) “variablistic” or “covering law” models are not the dominant way of making causal claims, (2) research methods affect but do not determine causal usage, and (3) the use of explicit causal language and the concept of “mechanisms” to make causal claims is limited. Instead, we find that metaphors and metaphoric reasoning are fundamental for causal claims‐making in the discipline. On this basis, we define three dominant causal types used in sociology today, which we label the Probabilistic, Initiating and Conditioning types. We theorize this outcome as demonstrating the primary role that cognitive models play in providing inference‐rich metaphors that allow sociologists to map causal relationships on to empirical processes. 相似文献
