Measuring business performance in the high-tech manufacturing industry: A case study of Taiwan's large-sized TFT-LCD panel companies

The nature of competition in the high-technology manufacturing industry has changed dramatically over the last two decades, and any of the traditional indicators of business performance are insufficient today. We have identified a new set of financial and non-financial performance indicators that can be used by high-tech manufacturing companies and have developed a business performance evaluation model. A data envelopment analysis (DEA), an analytic hierarchy process (AHP), and a fuzzy multi-criteria decision-making approach are used in the model. Data from large-sized thin-film transistor liquid-crystal display panel companies in Taiwan were collected via a field survey and from various published databases and were fed into the model to determine the relative business performance of the companies. We hope that our findings will help high-tech manufacturing executives determine their companies’ strengths and weaknesses and lead to future improvements in business operations.     

Properties and performance of one-sided cumulative count of conforming chart with parameter estimation in high-quality processes

The one-sided cumulative count of conforming (CCC) chart is a useful method to monitor nonconforming fraction in high-quality manufacturing processes. The nonconforming fraction parameter is assumed to be known when implementing a one-sided CCC chart. In this study, we investigated the impact of estimated nonconforming fraction, [pcirc] ₀, in a one-sided CCC chart. The run length distribution is derived as well as the conditional probability of a false alarm rate (CFAR), conditional average run length (CARL) and its standard deviation (CSDRL). Simulation results are conducted to evaluate the effect of [pcirc] ₀ in a one-sided CCC chart. The results show that values of CFAR, CARL and CSDRL are close to the nominal values for a large sample. The impact of estimation errors was also studied. We find that CFAR decreases for large [pcirc] ₀. Thus, a large value of [pcirc] ₀ is suggested for fewer false alarms.     

Fast Initial Response Features for Poisson GWMA Control Charts

The Poisson GWMA (PGWMA) control chart is an extension model of Poisson EWMA chart. It is substantially sensitive to small process shifts for monitoring Poisson observations. Recently, some approaches have been proposed to modify EWMA charts with fast initial response (FIR) features. In this article, we employ these approaches in PGWMA charts and introduce a novel chart called Poisson double GWMA (PDGWMA) chart for comparison. Using simulation, various control schemes are designed and their average run lengths (ARLs) are computer and compared. It is shown that the PDGWMA chart is the first choice in detecting small shifts especially when the shifts are downward, and the PGWMA chart with adjusted time-varying control limits performs excellently in detecting great process shifts during the initial stage.     

An alternative estimator for randomized response sampling with continuous distributions from a dichotomous population

In this paper, we introduce an alternative estimator of a population proportion from a dichotomous population when using randomized response sampling with continuous randomizing distributions. We also propose the alternative use of exponential randomizing densities. The estimator is obtained by method of moments and is compared with Franklin's (1989) estimator using normal and exponential distributions. The proposed estimator is more efficient than Franklin's (1989) estimator under suitable conditions for the two distributions.     

A Mathematical Model Relating Cohort And Period Mortality

This paper presents a mathematical model for changing mortality in functional form. This model may be used to obtain cohort forces of mortality and cohort survivorship functions from a period force of mortality and a period life table under conditions of gradually changing mortality if an estimate of the amount of change in mortality is available. An example is given to show how the cohort functions are derived from the period functions.     

Reaching the hard to reach: innovative housing for homeless youth through strategic partnerships

This article features three housing programs designed to target the needs of youth aging out of child welfare. One program combines housing and treatment to move substance-dependent youth off the streets; one combines the resources of Urban Peak, the only licensed homeless and runaway youth shelter in Colorado, with the Denver Department of Human Services to prevent youth in child welfare from discharging to the streets; and one addresses the intense mental health needs of this population. It costs Colorado 53,655 dollars to place a young person in youth corrections for one year and 53,527 dollars for residential treatment. It costs Urban Peak 5378 dollars to move a young person off of the streets. This article describes how data have driven program development and discusses how policy implications and relationships with the public and private sector can leverage additional resources.     

The South Oaks Gambling Screen Revised for Adolescents (SOGS-RA): Further Psychometric Findings from a Community Sample

The broad expansion of gambling across North America during the last two decades has generated concern about the extent of gambling and problem gambling in youth, and the need to more accurately monitor it. The South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA) is a promising instrument for screening problem gambling (Winters, Stinchfield, & Fulkerson, 1993) that requires more evaluation. Accordingly, further psychometric analysis of the instrument was conducted as part of a community survey of gambling in a sample of 1,000 male and female youth, aged 12 to 17 years. The analyses extended previous focus by including females, young adolescents, and an evaluation of youth classified as at-risk. Consistent with preliminary findings obtained during scale development, the distribution of item endorsement revealed trends of over-endorsement for some items (e.g., gambled more than intended, felt bad about the amount bet), and under-endorsement for others (e.g., criticized or told you had a gambling problem). These results suggest consideration of some form of weighting procedure, item deletion or re-wording. A factor analysis of the SOGS-RA items suggested a two-factor solution, with one factor interpreted as Control over Gambling and the other Gambling Consequences. It is proposed that the two factors may represent early versus more severe levels of gambling problems, respectively. The results highlight the need for further psychometric evaluation and refinement of instruments used to identify gambling problems in young people.     

Vocational outcomes of individuals with psychiatric disabilities participating in a supported competitive employment program

The objective of this paper is to report on the vocational outcomes of individuals with psychiatric disabilities participating in a supported competitive employment (SCE) program. A total of 458 subjects enrolled in the present SCE program which was developed on the basis of the Supported Employment Model developed by Wehman [23] and the principles of the Individual Placement and Support (IPS) developed by Becker and Drake [5]. Of the 458 subjects, 308 (67.3%) obtained competitive employment. The mean job tenure was 134 days. The mean salary was $4,740 for full-time jobs and was $2,321 for part-time jobs. The majority of subjects (59.4%) could sustain their job placement for more than 30 days, 74 (24.0%) subjects could work for more than six months, and 38 (12.3%) could maintain the job for more than one year. Subjects who became employed were compared to those who did not gain employment on a variety of demographic variables. Significant differences were found between two groups in terms of sex and source of referral. The rate of employment in the current study was slightly higher, but the job retention rate was lower than in earlier studies. Recommendations for future research on evaluation of the effectiveness of SCE program are suggested.     

The development of supported employment services for people with mental illness: local experience in Hong Kong

Before the 1960s in Hong Kong, specialized vocational services for people with mental illness were very limited, and sheltered workshop seemed to be the only option for their future vocational placement at that time. As discussed in the literature, there are still many shortcomings of the sheltered workshop model, that brings us to the emergence of another community-based vocational service: Supported Employment. Unlike traditional vocational services, the concept of supported employment emphasizes the placing of the clients into integrated work environments and then providing on-going support and work-related skills training in the job post. Though supported employment services help many clients to sustain a job in the competitive market, many service barriers and problems still remain unsolved. These service barriers and problems will be discussed in this article, and suggestions will be made.     

Family Structure and Children's Socioeconomic Attainment: A Canadian Sample

With the proliferation of different family forms in many western countries over the last few decades, research investigating the influence of family structure on children's socioeconomic status attainment has expanded dramatically, especially in the United States. The purpose of this study was to estimate the relative influence of family structure, maternal resources, and family mental health on predicting socioeconomic attainment in young adulthood. Data for this study were derived from a case‐comparison, three‐wave panel study of single‐parent, and two‐parent families living in London, Ontario, with interviews conducted in 1993 (wave 1), 1994 (wave 2), and between 2005 and 2008 (wave 3). There were virtually no differences in status attainment by family structure. Unexpectedly, however, we found that children raised in temporally stable single‐parent families, and those whose mothers transitioned from a single‐parent family to a two‐parent family had higher socioeconomic status occupations for their longest job held than did children raised in temporally stable two‐parent families. Maternal education was positively related to the likelihood that children would graduate from college/university. For those concerned with social policy, this implies that greater attention ought to be paid to addressing disparities in education and family income than to concerns with the kinds of families in which children grow up. Avec la prolifération de différentes formes de familles dans plusieurs pays occidentaux depuis quelques décennies, la recherche sur l'influence de la structure da la famille sur l'acquisition de statu socioéconomique des enfants s'est dramatiquement élargie, surtout aux Etats‐Unis. L'intention de cette étude était d'estimer l'influence relative de la structure de famille, les ressources maternelles et la santé mentale de la famille sur la prédiction d'acquisition socioéconomique d'un jeune adulte. Les données de cette étude résultent d'une comparaison de cas, sur un échantillonnage de 3 séries de familles monoparentales et de familles à 2 parents vivant à London, Ontario, avec des entrevues réalisées en 1993 (série 1), 1994 (série 2) et entre 2005 et 2008 (série 3). Il n'y a avait virtuellement pas de différence d'acquisition de statu par structure de famille. De manière inattendue, cependant, nous avons établis que les enfants élevés de par des familles monoparentales stables dans le temps, ainsi que ceux dont la mère avait opéré une transition d'une structure monoparentale vers une structure à 2 parents, occupaient des fonctions d'un statu socioéconomique plus élevé durant leur période d'emploi la plus longue comparés aux enfants élevés dans des familles à 2 parents stables dans le temps. L’éducation maternelle était positivement liée à la probabilité que les enfants obtiendraient un diplôme d'un niveau post‐secondaire (collège / université). Pour ceux concernés par les politiques sociales, cela induit qu'une plus grande attention devrait être accordée à la disparité entre l’éducation et les revenus de la famille plutôt que de s'attarder sur les types de famille dans lesquelles les enfants grandissent.
