The purpose of the current study was to investigate the awareness and knowledge status of physical education candidate students about physical education lessons designed for disabled individuals. A qualitative data collection technique was used in order to present the knowledge and awareness status of candidate students. Research conducted during the 2017–2018 fall semester with 30 4th grade students. By using the interview technique students questioned if physical education for disabled course composed awareness and increased their knowledge about disabled with three questions. The Data obtained accordingly were summed up and annotated according the pre-determined themes. Moreover, qualitative data were prepared by using the frequency and breakdown tables to form the numerical findings. The results revealed that the physical education candidates did not have knowledge about the physical education lessons designed for disabled individuals before taking the course and awareness status also found low (53.34%). However they stated that the physical education for disabled course changed their knowledge and awareness status (60%).

Recent research has emphasised that an increasing number of enterprises need computation environments for executing HPC (High Performance Computing) applications. Rather than paying the cost of ownership and possess physical, fixed capacity clusters, enterprises can reserve or rent resources for undertaking the required tasks. With the emergence of new computation paradigms such as cloud computing it has become possible to solve a wider range of problems due to their capability to handle and process massive amounts of data. On the other hand, given the pressing regulatory requirement to reduce the carbon footprint of our built environment, significant researching efforts have been recently directed towards simulation-based building energy optimisation with the overall objective of reducing energy consumption. Energy optimisation in buildings represents a class of problems that requires significant computation resources and generally is a time consuming process especially when undertaken with building simulation software, such as EnergyPlus. In this paper we present how a HPC based cloud model can be efficiently used for running and deploying EnergyPlus simulation-based optimisation in order to fulfil a number of objectives related to energy consumption. We describe and evaluate the establishment of such an application-based environment, and consider a cost perspective to determine the efficiency over several cases we explore. This study identifies the following contributions: (i) a comprehensive examination of issues relevant to the HPC community, including performance, cost, user perspectives and range of user activities, (ii) a comparison of two different execution environments such as HTCondor and CometCloud and determine their effectiveness in supporting simulation-based optimisation and (iii) a detailed performance analysis to locate the limiting factors of these execution environments.  相似文献

Despite a lot of restructuring and many innovations in recent years, the securities transaction industry in the European Union is still a highly inefficient and inconsistently configured system for cross-border transactions. This paper analyzes the functions performed, the institutions involved and the parameters concerned that shape market and ownership structure in the industry. Of particular interest are microeconomic incentives of the main players that can be in contradiction to social welfare. We develop a framework and analyze three consistent systems for the securities transaction industry in the EU that offer superior efficiency than the current, inefficient arrangement. Some policy advice is given to select the ‘best’ system for the Single European Financial Market.  相似文献

Smell is considered to be the sense that is most closely attached to emotional reactions. This makes scent in the hotel environment an important atmospheric variable to study, because fragrances are expected to increase the likelihood of producing an emotional reaction from consumers. Capitalizing on smell’s ability to cue memories and conjure up emotions, the purpose of this research is to examine the emotional states evoked by various hotel scents in a hotel business in Hong Kong that uses scent throughout its premises. More specifically, this study intends to make a connection between the emotional states evoked by the hotel scents and how hotel businesses can make use of their guests’ emotional responses. Scent marketing is an overlooked subject in hospitality and tourism research.  相似文献

In this paper, we study consumers with limited memory and examine the effects of their price categorization on the pricing strategies of competing firms. The valuations of consumers are assumed to be heterogeneous. We find that it is possible to observe price dispersion even when each firm charges a single price if the consumers categorize prices non‐optimally. Moreover, we demonstrate that the likelihood of a price dispersion outcome is reduced when consumers with limited memory set up the price categories optimally. These findings suggest that the consumers' limited memory and their sub‐optimal behavior, that is, their inability to choose price categories optimally can be a reason for observed price dispersion.  相似文献

Corporate governance research has extensively studied the relationship between outside board characteristics and outside board involvement. We add to this literature by investigating the extent to which interactions between outside board members and the top management team (TMT) affect the functioning of the outside board. Building on conflict theory, our study shows that conflict between TMT and outside board is an important antecedent for outside board service involvement. Specifically, drawing from a hand‐collected data set of 70 high‐tech start‐ups in Belgium, we find that TMT–outside board task conflict is both directly and indirectly, that is, through TMT–outside board relationship conflict, related to outside board service involvement.  相似文献

Profiles of exporting and superior-performing private small and medium-sized enterprises (SMEs) are presented. Multivariate regression evidence suggests that SMEs focusing upon an offensive and market differentiation strategy of product/service protection is associated with the propensity and the intensity of exporting. Exporting SMEs are also associated with younger and manufacturing firms as well as firms with product or service quality and/or technology resources. The perceptions by SMEs of external environmental turbulence were not significantly associated with the exporting-dependent variables. Most notably, variables associated with exporting SMEs are not the same as those associated with superior firm performance. Moreover, exporting firms did not report superior levels of performance. Implications for policy-makers, practitioners and researchers are discussed.  相似文献

Insights from contemporary psychology can illuminate the common psychological processes that facilitate unethical decision making. I will illustrate several of these processes and describe steps that may be taken to reduce or eliminate the undesirable consequences of these processes. A generic problem with these processes is that they are totally invisible to decision makers – i.e., decision makers are convinced that their decisions are ethically and managerially sound.  相似文献

This paper provides an alternative credit risk model based on information reduction where the market only observes the firm’s asset value when it crosses certain levels, interpreted as changes significant enough for the firm’s management to make a public announcement. For a class of diffusion processes we are able to provide explicit expressions for the firm’s default intensity process and its zero-coupon bond prices.   相似文献

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa.  相似文献
