Six Sigma Beyond Quality: A Concept of Management

Six Sigma was developed by Motorola in the mid-1980s. The essence of Six Sigma is to stop variations in quality at the earliest possible point by attacking variation during design of products and processes and to create a culture that demands perfection. The concept of Six Sigma is as a much-needed management program that has the highest impact on the bottom-line financials. The key focus of all Six Sigma programs is to optimize overall results at the business, operations, and process level within a company. The Six Sigma Breakthrough Strategy provides the tools to achieve the goal - 3.4 defects per million opportunities, through a highly focused system of problem solving. Six Sigma has a dis ciplined approach covering five phases: define, measure, analyze, improve, and control. The work of Six Sigma is led by the right people selected and trained in the Six Sigma methodology and establishes infrastructure - Master Black Belts, Black Belts, and Green Belts. The object of these training efforts is to have every employee make improvements in their work processes. What distinguishes Six Sigma from TQM is that each Six Sigma’s work team with solving a specific problem has a clear goal tied a financial incentive. When companies embark on Six Sigma quality programs, the object of technical viewpoint is to reduce the process variance and the objective of managerial or customer viewpoint being cost-effective is to adjust the process to the target value such as employee training in statistical problem-solving methods and techniques. That is why the Six Sigma long-term process is allowed to be off centering with 1.5 sigma shift to minimize the number of setups or tool changeovers

El papel del locus de control del jefe entre el guanxi percibido y la conducta de liderazgo en los negocios familiares

The special and historical relationship network in Chinese societies is based on blood ties or family emotional connection, in which family business appears the best representative. With the specialty of corporate structure, power and leadership between superiors and subordinates are the critical issues for research, where managers’ personality is particularly emphasized. We combine guanxi in Chinese societies, power, influence tactics, and locus of control in the research model, 147 family business in Taiwan are proceeded the questionnaire survey, and 332 valid copies are retrieved. With hierarchical regression analysis, the findings show the close relations between managers’ power, perceived guanxi and leadership behavior, in which managers’ locus of control play a critical role. It is therefore suggested that the assignation of managers in such type of enterprises should be more cautious; in addition to the communication with the subordinates, the fitness with personality and competence should be concerned in order to maintain the favorable work efficiency and the relations between superiors and subordinates.La histórica y especial red de relaciones de la sociedad china se basa en lazos de sangre o en conexiones familiares emocionales de las que los negocios familiares son la mejor representación. Junto con la especialización de las estructuras corporativas, la cuestión clave de esta investigación será el poder y el liderazgo de los jefes sobre los subordinados, poniendo el énfasis en la personalidad del jefe. En el modelo de investigación –administración de un cuestionario a 147 negocios familiares de Taiwán, de los que 332 fueron válidos- combinamos el “guanxi” de las sociedades chinas, el poder, las tácticas para tener influencia y el locus de control. Mediante análisis jerárquicos de regresión los resultados muestran la estrecha relación que se da entre el poder de los jefes, el “guanxi” percibido y la conducta de liderazgo, en la que el locusde control de los jefes desempeña un papel destacado. Por eso se recomienda que la designación de jefes en esas empresas sea más cuidadosa. Además de la comunicación con los subordinados, debe prestarse atención a la adecuación entre personalidad y la competencia para mantener una eficiencia laboral y unas relaciones entre jefes y subordinados favorables

The effect of adding a home program to weekly institutional-based therapy for children with undefined developmental delay: A pilot randomized clinical trial

AbstractBackgroundEarly rehabilitation for children with developmental delay without a defined etiology have included home and clinic programs, but no comparisons have been made and efficacy is uncertain. We compared a weekly visit for institutional-based therapy (IT) to IT plus a structured home activity program (HAP).MethodsSeventy children who were diagnosed with motor or global developmental delay (ages 6-48 months and mean developmental age 12.5 months) without defined etiology were recruited (including 45 males and 23 females). The outcomes included the comprehensive developmental inventory for infants and toddlers test and the pediatric evaluation of disability inventory.ResultsChildren who received only IT improved in developmental level by 2.11 months compared with 3.11 months for those who received a combination of IT and HAP (p = 0.000). On all domains of the comprehensive developmental inventory for infants and toddlers test, except for self-help, children who participated in HAP showed greater improvements, including in cognition (p = 0.015), language (p = 0.010), motor (p = 0.000), and social (p = 0.038) domains. Except on the subdomain of self-care with caregiver assistance, the HAP group showed greater improvement in all the pediatric evaluation of disability inventory subdomains (p < 0.05).ConclusionEarly intervention programs are helpful for these children, and the addition of structured home activity programs may augment the effects on developmental progression

An Overview of Regional Experiments on Biomass Burning Aerosols and Related Pollutants in Southeast Asia: From BASE-ASIA and the Dongsha Experiment to 7-SEAS

By modulating the Earth-atmosphere energy, hydrological and biogeochemical cycles, and affecting regional-to-global weather and climate, biomass burning is recognized as one of the major factors affecting the global carbon cycle. However, few comprehensive and wide-ranging experiments have been conducted to characterize biomass-burning pollutants in Southeast Asia (SEA) or assess their regional impact on meteorology, the hydrological cycle, the radiative budget, or climate change. Recently, BASEASIA (Biomass-burning Aerosols in South-East Asia: Smoke Impact Assessment) and the 7-SEAS (7- South-East Asian Studies) Dongsha Experiment were conducted during the spring seasons of 2006 and 2010 in northern SEA, respectively, to characterize the chemical, physical, and radiative properties of biomass-burning emissions near the source regions, and assess their effects. This paper provides an overview of results from these two campaigns and related studies collected in this special issue, entitled Observation, modeling and impact studies of biomass burning and pollution in the SE Asian Environment. This volume includes 28 papers, which provide a synopsis of the experiments, regional weatherclimate, chemical characterization of biomass-burning aerosols and related pollutants in source and sink regions, the spatial distribution of air toxics (atmospheric mercury and dioxins) in source and remote areas, a characterization of aerosol physical, optical, and radiative properties, as well as modeling and impact studies. These studies, taken together, provide the first relatively complete dataset of aerosol chemistry and physical observations conducted in the sourcesink region in the northern SEA, with particular emphasis on the marine boundary layer and lower free troposphere (LFT). The data, analysis and modeling included in these papers advance our present knowledge of source characterization of biomass-burning pollutants near the source regions as well as the physical and chemical processes along transport pathways. In addition, we raise key questions to be addressed by a coming deployment during springtime 2013 in northern SEA, named 7-SEASBASELInE (Biomass-burning Aerosols Stratocumulus Environment: Lifecycles and Interactions Experiment). This campaign will include a synergistic approach for further exploring many key atmospheric processes (e.g., complex aerosol-cloud interactions) and impacts of biomass burning on the surface-atmosphere energy budgets during the lifecycles of biomass burning emissions

Business analytics in industry 4.0: a systematic review

Recently, the term “Industry 4.0” has emerged to characterize several Information Technology and Communication (ICT) adoptions in production processes (e.g., Internet-of-Things, implementation of digital production support information technologies). Business Analytics is often used within the Industry 4.0, thus incorporating its data intelligence (e.g., statistical analysis, predictive modelling, optimization) expert system component. In this paper, we perform a Systematic Literature Review (SLR) on the usage of Business Analytics within the Industry 4.0 concept, covering a selection of 169 papers obtained from six major scientific publication sources from 2010 to March 2020. The selected papers were first classified in three major types, namely, Practical Application, Reviews and Framework Proposal. Then, we analysed with more detail the practical application studies which were further divided into three main categories of the Gartner analytical maturity model, Descriptive Analytics, Predictive Analytics and Prescriptive Analytics. In particular, we characterized the distinct analytics studies in terms of the industry application and data context used, impact (in terms of their Technology Readiness Level) and selected data modelling method. Our SLR analysis provides a mapping of how data-based Industry 4.0 expert systems are currently used, disclosing also research gaps and future research opportunities.The work of P.

Genome-wide association study of lung adenocarcinoma in East Asia and comparison with a European population.

Lung adenocarcinoma is the most common type of lung cancer. Known risk variants explain only a small fraction of lung adenocarcinoma heritability. Here, we conducted a two-stage genome-wide association study of lung adenocarcinoma of East Asian ancestry (21,658 cases and 150,676 controls; 54.5% never-smokers) and identified 12 novel susceptibility variants, bringing the total number to 28 at 25 independent loci. Transcriptome-wide association analyses together with colocalization studies using a Taiwanese lung expression quantitative trait loci dataset (n = 115) identified novel candidate genes, including FADS1 at 11q12 and ELF5 at 11p13. In a multi-ancestry meta-analysis of East Asian and European studies, four loci were identified at 2p11, 4q32, 16q23, and 18q12. At the same time, most of our findings in East Asian populations showed no evidence of association in European populations. In our studies drawn from East Asian populations, a polygenic risk score based on the 25 loci had a stronger association in never-smokers vs. individuals with a history of smoking (Pinteraction = 0.0058). These findings provide new insights into the etiology of lung adenocarcinoma in individuals from East Asian populations, which could be important in developing translational applications
