Single-Machine Sustainable Production Planning to Minimize Total Energy Consumption and Total Completion Time Using a Multiple Objective Genetic Algorithm

Abstract: Energy is an expensive resource that is becoming more scarce with increasing population and demand. In this paper, a mathematical model to minimize energy consumption and reduce total completion time of a single machine is proposed, and a multiobjective genetic algorithm is utilized to obtain an approximate set of nondominated alternatives. Furthermore, dominance rules and a heuristic are proposed to increase the speed of the proposed genetic algorithm. Finally, the analytical hierarchical process is utilized to select a solution with some additional criteria.

Empirical evidence of the association between the presence of musculoskeletal pain and physical disability in community-dwelling senior citizens

Abstract: The proportion of people 65 years of age and older who report musculoskeletal pain and physical disability is high. The main objective of this study was to determine whether physical disability was associated with the presence of musculoskeletal pain in a sample of senior citizens. Self-administered questionnaires were sent to a sample of 1306 community-dwelling senior citizens in London, Ontario, Canada between August and October 1995. The questionnaire included questions about pain, difficulty performing activities, depressive symptoms, chronic conditions, and demographic information. A total of 887 seniors completed the questionnaire (70.7% response rate, aged 65–94, 41.2% men, 58.8% women). Logistic regression analysis, without controlling for potential confounding variables, revealed that those who reported having musculoskeletal pain were seven times more likely to have some difficulty performing three or more activities listed in the questionnaire (OR=6.91 95% CI 4.92–9.69). When significant confounding variables were controlled in the analysis, seniors who reported musculoskeletal pain were still three times more likely to have some difficulty with three or more activities (OR=2.93, 95% CI 1.96–4.38). Although no causal relationship can be inferred, thorough pain assessment and pain management may be important in the maintenance of independent living for adults 65 years of age or older.

Physical fitness and adults with mental retardation : an overview of current research and future directions

Abstract: The deinstitutionalisation movement of the past 25 years has focused on the placement of people with mental retardation into community-based settings. There is a need for exercise- and health-related professionals to demonstrate a thorough understanding of the term mental retardation and all of the intellectual and behavioural ramifications that coexist with this condition before addressing the ‘how to’ of fitness evaluation. Therefore, the article outlines the range of intellectual and behavioural characteristics of this population, based on the level of retardation.

Firm and industry effects on firm performance: A generalization and extension for new ventures

Abstract: Our study extends a long-running debate into the domain of entrepreneurship by examining firm and industry effects on the performance of new ventures. We examine to what extent firm and industry levels explain sales, sales growth, and survival among 7,256 young Swedish firms over a five-year period, and compare these findings to a sample of 12,692 established firms. We found that the industry level ‘matters’ little for the survival of either sample of firms, and industry membership matters less for the sales and sales growth of new ventures than for established firms. Post hoc analysis revealed that size affects new venture performance, and that new venture funding is related to both sales and survival. At a broad level, our findings shed new light on the roles of the liabilities of newness and smallness for the performance of new ventures. Copyright © 2009 Strategic Management Society.
