Objectives: The purpose of this study was to determine whether cardiorespiratory fitness and leisure time physical activity in men screening positive for ADHD were low compared to age- and sex-matched reference values. Methods: 30 college men screening for ADHD were recruited. Data were collected between October 2014 and April 2015. Maximal cycle exercise tests were performed to assess cardiorespiratory fitness and typical 7-day leisure time physical activity was self- reported. Results: Mean cardiorespiratory fitness was 0.94 SD lower than age- and sex-matched reference values. Cardiorespiratory fitness and ADHD symptoms were significantly negatively associated (r= -.39). Leisure time physical activity was 0.3 SD lower than a prior study of 411 college students. A linear regression showed a significant prediction of cardiorespiratory fitness from the combination of ADHD symptoms and leisure time physical activity. Conclusions: Men screening positive for ADHD was characterized by low cardiorespiratory fitness and leisure time physical activity.

Marketing Standardization and Firm Performance in International E.Commerce

Fritz, Wolfgang,Dees, Heiko Korean Academy of Marketing Science 2009 마케팅과학연구 Vol.19 No.3

The standardization of marketing has been one of the most focused research topics in international marketing. The term "global marketing" was often used to mean an internationally standardized marketing strategy based on similarities between foreign markets. Marketing standardization was discussed only within the context of traditional physical marketplaces. Since then, the digital "marketspace" of the Internet had emerged in the 90's, and it became one of the most important drivers of the globalization process opening new opportunities for the standardization of global marketing activities. On the other hand, the opinion that a greater adoption of the Internet by customers may lead to a higher degree of customization and differentiation of products rather than standardization is also quite popular. Considering this disagreement, it is notable that comprehensive studies which focus upon the marketing standardization especially in the context of global e-commerce are missing to a high degree. On this background, the two basic research questions being addressed in this study are: (1) To what extent do companies standardize their marketing in international e-commerce? (2) Is there an impact of marketing standardization on the performance (or success) of these companies? Following research hypotheses were generated based upon literature review: H 1: Internationally engaged e-commerce firms show a growing readiness for marketing standardization. H 2: Marketing standardization exerts positive effects on the success of companies in international e-commerce. H 3: In international e-commerce, marketing mix standardization exerts a stronger positive effect on the economic as well as the non-economic success of companies than marketing process standardization. H 4: The higher the non-economic success in international e-commerce firms, the higher the economic success. The data for this research were obtained from a questionnaire survey conducted from February to April 2005. The international e-commerce companies of various industries in Germany and all subsidiaries or headquarters of foreign e-commerce companies based in Germany were included in the survey. 118 out of 801 companies responded to the questionnaire. For structural equation modelling (SEM), the Partial-Least. Squares (PLS) approach in the version PLS-Graph 3.0 was applied (Chin 1998a; 2001). All of four research hypotheses were supported by result of data analysis. The results show that companies engaged in international e-commerce standardize in particular brand name, web page design, product positioning, and the product program to a high degree. The companies intend to intensify their efforts for marketing mix standardization in the future. In addition they want to standardize their marketing processes also to a higher degree, especially within the range of information systems, corporate language and online marketing control procedures. In this study, marketing standardization exerts a positive overall impact on company performance in international e-commerce. Standardization of marketing mix exerts a stronger positive impact on the non-economic success than standardization of marketing processes, which in turn contributes slightly stronger to the economic success. Furthermore, our findings give clear support to the assumption that the non-economic success is highly relevant to the economic success of the firm in international e-commerce. The empirical findings indicate that marketing standardization is relevant to the companies' success in international e-commerce. But marketing mix and marketing process standardization contribute to the firms' economic and non-economic success in different ways. The findings indicate that companies do standardize numerous elements of their marketing mix on the Internet. This practice is in part contrary to the popular concept of a "differentiated standardization" which argues that some elements of the marketing mix should be adapted local

The study determined the efficiency and performance of the distribution chain of marine capture fisheries in Lucena Fish Port Complex, Lucena City, Philippines. A survey using a pre-tested questionnaire was conducted among 125 respondents consisting of fishermen, traders, truckers, wholesalers and retailers. Simple random sampling was used to identify the fishermen, traders and retailers while complete enumeration was done in the case of truckers and wholesalers. Descriptive, product flow, value chain and cost and return analyses were employed in the study. Based on the performance measures used in the study, including the gross margins computed, the performance of the distribution and transportation system of marine capture fisheries products in Lucena Fish Port Complex can be considered inefficient due to high transportation rates, high spoilage rate, and longer traveling hours than what is expected. The study recommended technology development for improved operations, introduction of the open bidding system to prevent information asymmetry, practice of responsible fishing, key players to assume other roles in the chain, planning ahead the use of alternative roads, ensuring proper management practices, construction of paved roads. securing fishing permits and full utilization of the cold storage facility.

Evaluation of Energy Efficiency in Cutting Aerospace Materials with High-Pressure Cooling Lubricant Supply

Fritz Klocke,Tolga Cayli,Dieter Lung,Benjamin Döbbeler,Hubertus Sangermann 한국정밀공학회 2014 International Journal of Precision Engineering and Vol. No.

In the field of machining difficult-to-cut materials like titanium or nickel-based alloys, the use of high-pressure cooling lubricantsupply (HPCLS) offers huge potential to significantly increase productivity and process stability. Due to enhanced cooling andlubrication of the cutting zone, tool wear can be decreased which allows higher applicable cutting speeds. Furthermore, processstability can be increased through effective chip breaking and evacuation. Increasing energy prices and legislative frameworkconditions, require energy efficient machine tools and processes. Since additional energy is required to run the high-pressure pump,it has to be determined if the overall process is still energy-efficient due to the increase in productivity resulting in shorter cycle times. In this paper the overall aim is to evaluate the conventional-flood-cooling and HPCLS in terms of economics and energy efficiency. Therefore a case study has been performed in which the energy consumption and production times for machining a rotationallysymmetric jet engine part made of Inconel 718 were compared for both conventional and HPCLS. Furthermore, an ecologicalevaluation has been conducted to determine the advantageousness of the HPCLS. Due to the rising necessity of suppliers to providea product carbon footprint, a methodology for assessing the footprint has been applied.

Purpose – The study assessed the influence of some variables relevant to vegetable farmers’ decisions in farm machinery usage. The decision of farmers in using farm machineries is determined by a number of social, technical, environmental and economic factors. Design/Methodology/Approach – The binary logit model was employed to determine the relationship of the predetermined factors on farmers’ use of a single-specific farm machine. Furthermore, the study utilized negative binomial regression to assess the factors influencing the decisions of farmers in using various farm machineries in their farming operations. Findings – Results showed that majority of the farmers still follow traditional farming methods using very limited farm technologies. Farmers face the challenge of optimizing their land use, and this includes their decision whether or not to use farm machineries in their farming operations in order to boost production. Various factors are considered, more than just the cost of technology. Thus, a combination of household-specific, economic, technology, institutional and moderating factors influences the technology adoption decisions of vegetable farmers. Moreover, it was revealed that formal education, household size, household income, cash availability, farm size, access to extension workers, attendance in seminars, trainings and workshops, and on-farm demo participation are all positively related to the probability of farmers’ usage of identified farming machines. Conversely, farming experience, cost of technology, technology triability, credit access, and farm distance to market are all found to be negatively related to the probability of farmers’ usage of farm machineries. Research Implications – Various recommendations were offered to address challenges encountered by farmers in terms of farm machinery usage including changing the farmers’ mindset from a traditional perspective to a market-oriented one via the R.E.S.E.T. model.
