Evaluating the Efficiency of Governmental Excellence for Social Progress: Focusing on Low- and Lower-Middle-Income Countries

Social Indicators Research - As the “weak-institutions trap” is increasingly recognized as the major hindrance to growth, the advantages offered by e-government may provide an...     

Minimizing makespan in an ordered flow shop with?machine-dependent processing times

We consider a generalization of the proportionate flow shop problem with the makespan objective. Each job has a processing requirement and each machine has a characteristic value. In our case, we assume that the time a job occupies a machine is equal to the processing requirement of the job plus a setup time that is equal to the characteristic value of that machine. In this paper, we consider permutation schedules and show that the problem is solvable in polynomial time when the number of machines is fixed.     

Container Scheduling: Complexity and Algorithms

We consider the transport of containers through a fleet of ships. Each ship has a capacity constraint limiting the total number of containers it can carry and each ship visits a given set of ports following a predetermined route. Each container has a release date at its origination port, and a due date at its destination port. A container has a size 1 or size 2; size 1 represents a 1 TEU (20‐foot equivalent unit) and size 2 represents 2 TEUs. The delivery time of a container is defined as the time when the ship that carries the container arrives at its destination port. We consider the problem of minimizing the maximum tardiness over all containers. We consider three scenarios with regard to the routes of the ships, namely, the ships having (i) identical, (ii) nested, and (iii) arbitrary routes. For each scenario, we consider different settings for origination ports, release dates, sizes of containers, and number of ports; we determine the computational complexity of various cases. We also provide a simple heuristic for some cases, with its worst case analysis. Finally, we discuss the relationship of our problems with other scheduling problems that are known to be open.     

Bringing Japanese Continuous Improvement Approaches to U.S. Manufacturing: The Roles of Process Orientation and Communications*

Continuous improvement (CI) has played a key role in Japan's quality management. U.S. companies have begun to adopt CI in recent years. This paper studies the implementation of CI in seven U.S. manufacturing companies. We view values as the core concept of culture that impacts CI effectiveness. Using both qualitative and quantitative data with a sample of seven companies, we observe empirically a relationship between process-oriented values and CI effectiveness. We also find that communications involving workers is strongly associated with CI effectiveness. Finally, we find an association between process orientation and communication frequency, and argue that communications act as an intervening variable between process orientation and effectiveness.     

Determinants of engagement in paid work following social security benefit receipt among older women

Work behavior among older men approaching or following retirement has received considerable research attention over the past two decades, but research on older women's work behavior is still in its incipient stage. Based on data from the 1982 New Beneficiary Survey (NBS) and the 1991 New Beneficiary Follow-up (NBF), this study analyzes the extent and determinants of employment among women who received their first Social Security benefits between 1980 and 1981. More than one fourth of the women continued to work or rejoined the labor force following their first Social Security benefit receipt. Financial need was found to be the primary reason for and the most significant determinant of women's continuing work or (re)entry into the labor force. But the level of education, health, spouse's work status, and previous work history were also found to be significant determinants of the likelihood and duration of their employment following Social Security receipt.     

The age old question, which comes first? A simultaneous test of children's savings and children's college-bound identity

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.     

Social skills training and parent education programs for aggressive preschoolers and their parents in South Korea

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.     

Wisdom from life's challenges: qualitative interviews with low- and moderate-income older adults who were nominated as being wise

Previous wisdom research tended to focus on cognitive and intellectual aspects, highly educated professionals and/or prominent subjects, and wisdom as the outcome not process. In this study, based on in-depth interviews of 18 low- and moderate income older adults who were nominated as being wise by their aging-service providers, we explored the ways challenging life experiences and coping may have contributed to the development of their wisdom, their ideas/beliefs about the qualities of wisdom, and the ways they may be practicing wisdom in daily life. Their emphasis on interconnectedness and interdependence, forgiveness and patience, and gratitude appears to represent self-transcendental qualities of wisdom. Social work practice and research implications are discussed.     

The Development and Initial Psychometric Evaluation of the Korean Career Stress Inventory for College Students

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.
