The purpose of this study was to evaluate a group activity, reciprocal peer tutoring (RPT), in order to investigate advantages and challenges of RPT in promoting cooperative and collaborative learning environment for EFL University reading instruction. The participants in this study were 89 students taking an English reading course at a Korean university. RPT is a learning strategy whereby learners help each other and learn by teaching. This program was supported by a Vygotskyan perspective which assumes that learners gain mastery and develop cognitive skills through social interaction with more proficient others and their environment. This study relied particularly on participant perceptions through questionnaire survey and Anonymous Online class Report of the course. This study showed various advantages for tutors such as learning through teaching and becoming more autonomous and responsible for their own learning. Non-threatening and highly motivating learning atmosphere are parts of benefits for tutees. Other advantages for tutees included improved level of academic self-confidence, and motivation. This study also revealed several drawbacks associated with the problem of inaccuracy in students' production and students' demand for more direct teacher role. (182 words).

The standard theory of production treats human and non-human inputs in the same way. Inert Areas Theory drops this assumption. One distinction is obvious. Human capital, the source of human inputs, can not be purchased outright by firms. Usually what is purchased are units of labor time. What is critical is directed effort, at or beyond some level of skill. Direct effort, however, involves choice and motivation, and these are the critical variables left out of the standard theory. Leibenstein introduces the concept of "inert areas" by which he means "a set of effort positions whose associated levels of utility are not equal but in which the action required to go from a lower to a higher utility level involves a utility cost that is not compensated for by the gain in utility." This idea is used when discussing the behavior of firm's management.f firm's management.

Although renewable energy sources are more environmentally friendly than fossil energy sources, it is far more costly, considering current technological standards. It would not present many competitive advantages in the power market. If the renewable electricity is viable in the market, the government should take 'visible' actions to compensate production costs. Popular policies, such as Feed-In-Tariff and Renewable Portfolio Standards, can help to attract investors into generators of renewable electricity. But presently, they are mainly financed through a undifferentiated increase of electricity bills and occasionally confronted with the opposition of the electricity consumers. And most policies tend to focus on increasing the supply of renewable electricity with little consideration toward elevating the motivation of consumers. This study evaluates the potential of environmentally friendly energy consumption and examines the 'green pricing' program which realize the potential.

The System of Rice Intensification (SRI) has been spread very quickly in southern Cambodia. To understand the motivation of farmers in adapting SRI, and its benefits, we conducted an on-farm study at Popel commune, Tramkak district, Takeo province in southern Cambodia, during the 2012 and 2013 wet season. We noticed a significant difference between SRI and conventional farmers' practices (FP) in rainfed lowland rice ecosystem. Despite of low nitrogen input, without chemical fertilizers, high grain yield was achieved in SRI 1 (6.0 t ha) and SRI2-Bottom ($7.2t\;ha^{-1}$) in 2013. SRI 1 and SRI 2 of panicle and number of panicle were high than SR 3, FP 2, and FP 3 due to early transplant. Relationships between total number of spikelet and plant nitrogen were ($r^2=0.95$) highly positive at harvest. SRI fields were, most of them achieving highly superior yield and number of panicle compared to their FP fields. The results indicated that SRI practices of planting younger seedling, with organic material and topography of paddy, lead to increased grain yield.

MMORPG Quest plays a strong role of motivation through compensation related with Avatar such as items and experience points rather than a role of story transfer. This situation finally made MMORPG become a difficult game that players should study the compensation of Quest for growth of a character, so it causes fixation of the user class. As a solving method of the fixation of the users, the possibility of Quest capable of strengthening play motive of various users through clarification of motivation structure of the Quest play and pluralistic understanding about players was investigated. This is a direct response to the user within the game system or how to use the player log information. The pluralistic understanding method of players will have values as a tool that can guarantee the objectivity and actual production of the data collected utilizing.

Business boundaries of firms in the construction industry are strictly regulated in Korea. Under the current law, firms involved in construction processes are classified into five categories; general contractors, specialty contractors, architects' offices, engineering firms, and specialized in inspection. Among these types of firms, general contractors are prohibited to enter into specialty contractor's market and vice versa by the basic law in the construction industry. Also general contractors are not allowed to provide architectural services. The purpose of the law is to prohibit unlicensed companies from entering the construction market and to protect customers. However, the law causes critical problems e.g. low efficiency of production and rent creation. Therefore, we identify problems concerning business boundaries of firms in the construction industry and predict structural changes in the them when they are liberalized. So we surveyed general contractors and specialty contractors in Korea to estimate the effects of the liberalization on the construction industry. Most of contractors point to the enhancement of production efficiency as the motivation to integrate other construction process. If current regulations, which limit firms' decisions on business boundaries, are eliminated, firms will choose optimal business scopes taking into account types of contracts adopted by the Government for public works. Based on the cost/benifit analyses, they will decide whether to intergrate other production processes or not.

Since Lean Construction has been introduced in 1992, much research is in progress to popularize lean concepts and principles. Most research focuses on developing lean concepts and tools and strengthening the limited domain of instrumental rationality and technical efficiency. However, the basic concepts of human resource management seem to be ignored by those who advocate lean production. Thus, the lean construction research related to human resource management must be once considered for popularization and activation of lean construction at the beginning stage in the domestic construction industry. Because human resources have a major influence on lean implementation and its success, especially at the beginning stage of lean construction. This paper considers the human resource requirements for the implementation of lean construction in the USA construction industry. The results from the study will provide the foundations to adapt lean construction into the domestic construction industry. Consequently, the study found that lean construction could improve the capability of human resource and human motivation if effectively implemented in the construction sites. Since lean construction emphasizes and focuses on improvement of relationships among project participants, constant application to human resource management is crucial for successful lean implementation.

Nowadays, online reviews have become a common word of mouth that many users produce and consume. Posting online reviews is a kind of job that consumers do themselves. Since posting online reviews is not mandatory, it entirely relies on the consumer's voluntary willingness. In this respect, this study aims to describe the motivation for posting online reviews and their behavior processes, such as why online reviewers generate reviews and what types of reviews they create. In this study, we have conducted an in-depth study with 18 participants who have experience in posting reviews. By analyzing interview manuscripts from the grounded theory method approach, we have ultimately presented motivating factors for review posting (mutual reciprocity, material rewards), determinants of review browsing (trust toward review contents, preference for review format), and shadow work (a job that must be done, voluntary data production, consumer's share). We have also proposed the dynamics between core dimensions for theorizing a cycle process of review production and consumption. Our findings could bridge the gap in the existing online review research and offer practical implications for platform companies that need review management.

This study aims to investigate the factors which impact the possibility of Environmental Management Accounting (EMA) implementation in automobile companies in Vietnam. A survey was carried out with automobile enterprises' managers, getting 198 usable respondents, with data and theoretical model analyzed by using SPSS with EFA method. Results indicated that in Vietnamese automobile enterprises, the possibility of EMA implementation was driven by elements including motivation to reduce production costs, reactions to environmental issues, compliance to legislation, procedures and processes in the working environment which they are in business. The government and professional institutions should play a vital role in promoting EMA practices by issuing specific guidelines and continuous training. Besides, tax authorities should apply the favor policies such as tax incentives to stimulate interest enterprises to implement EMA. However, this study's results only reflect about 63.7% of the impact to the implementation of EMA in Vietnamese automotive enterprises, so there are still some other factors that should be found out in the future researches. This is the first attempt to systematically analyze enterprises' perception and willingness to apply EMA in Vietnamese automobile industry. This study contributes to not only the existing empirical literature of EMA but also enterprises' managers in Vietnam and other transitional economies.

The increasing demand for energy in the near future has created strong motivation for environmentally clean alternative energy resources. Microbial fuel cells (MFCs) have opened up new ways of utilizing renewable energy sources. MFCs are devices that convert the chemical energy in the organic compounds to electrical energy through microbial catalysis at the anode under anaerobic conditions, and the reduction of a terminal electron acceptor, most preferentially oxygen, at the cathode. Due to the rapid advances in MFC-based technology over the last decade, the currently achievable MFC power production has increased by several orders of magnitude, and niche applications have been extended into a variety of areas. Newly emerging concepts with alternative materials for electrodes and catalysts as well as innovative designs have made MFCs promising technologies. Aerobic bacteria can also be used as cathode catalysts. This is an encouraging finding because not only biofouling on the cathode is unavoidable in the prolonged-run MFCs but also noble catalysts can be substituted with aerobic bacteria. This article discusses some of the recent advances in MFCs with an emphasis on the performance, materials, microbial community structures and applications beyond electricity generation.
