Purpose: As sharing economy is becoming increasingly relevant to people's lives, we want to understand why people participate in the sharing economy. We propose and validate three factors that are likely to influence consumers' choice of participating in the sharing economy at distribution market. Also, we found antecedents that affect these variables. These antecedents include appointment and return convenient, extended operating time, variety-seeking need, usage irregularity, other's clean usage, and feeling of membership between users. Research design, data, and methodology: This research collected 341 questionnaire data from participants in China. These participants were asked about the usage of DiDi, the most popular shareware in China. The data analysis and hypothesis testing were conducted using SPSS and Amos. Results: Usage convenience, usefulness of short-term usage, and trust in other users were found to have a positive impact on consumers' intention to participate in the sharing economy. In addition, we found that all the antecedents affect these variables positively. Conclusions: This research provides new driving factors for consumer participation in the sharing economy. Moreover, these findings will help managers develop marketing strategies for inducing the consumers to participate in the sharing economy.

Demand of spectrum resource is tremendously increasing recently and this trend will continues in the future due to the wide spread of IT services based on cloud computing and Internet of Things technology and as well as smart devices. Recently, spectrum sharing technology has drawn attention to the spectrum policy makers as a promising way to overcome the shortage problem of scarce spectrum resource. To succeed in commercialization of spectrum sharing technology, it is necessary to prospect the future business ecosystem of spectrum sharing and develop appropriate policies and laws at the same time along with the advance of spectrum sharing technology. The purpose of this paper is to analyze casual relationships between enablers in future business ecosystem of spectrum sharing and propose policies to vitalize spectrum sharing ecosystem based on a system dynamics causal map proposed in the previous research. With the causal map and system dynamics method, it is possible to analyze feedback loops exist in the business ecosystem of spectrum sharing and build policies which optimize positive dynamics in business ecosystem of spectrum sharing. As a result, policy leverages were found in four areas; spectrum supply, spectrum demand, spectrum quality and technology, and spectrum transaction cost. For those policy leverages, 13 policies were identified and intervention timing for each policy was discussed. Finally, the promotion policies of government and market participants to vitalize spectrum sharing ecosystem were discussed.

This study examined food sharing characteristics revealed in the modern Korean society by both interpreting phenomena and analyzing literature. Diet was said to be the least influenced by western modernization in Korea. Concerning this matter, one of the important explanations to be considered would be a strong influence of 'the first settlement effect' in culture, as reviewed elsewhere. Sharing food means not only sharing food itself but also sharing communal solidarity. The latter was strongly emphasized in Korean food culture due to his own historical grounding. Some examples revealed in current Korea included sometimes too much generous treat when eating out, even saliva allowed food sharing, too much food provision, and too many restaurants. 'Dutch treat' observed in many occasions of food sharing in Korea was also viewed as a product of historical experience, which was related to the degree of traits of feudalism in modern societies as feudalism was based on a sort of a give and take contract. The association of the degree of traits of feudalism and communal solidarity was explored by comparing so called different meal treat manners between Koreans and Japanese, that is, more generous attitude among the former. The concept of communal solidarity was also examined with respect to Koreans' side dish sharing behaviors which sometimes accompanied seemingly insanitary saliva sharing. In addition, provision of too much food was analyzed by relating this manner to a traditional 'hand over dining table' custom. Traditionally, food on a dining table was not supposed to be only for those sitting on the table. Even though the 'hand over dining table' was no longer well preserved at present time, its cultural traits appeared to be well prevailed in the modern Korean society. Finally, an increase of restaurants as well as an increase of eating out occasions were postulated with respect to the notion that restaurants were the places for ascertaining communal solidarity while sharing foods. The above analyses suggest the importance of the influence of sharing originated from his/her own historical grounding for better understanding of modern Korean food culture.

Currently, studies have show that the network related energy consumption are increasing. and part of overall energy consumption of our society are too. So, that is important to look for energy-efficient network applications and protocols. A most of network energy consumption are due to network edge devices. in this paper, in order to cut down the emissions of carbon dioxide from ICT business, which contributes 2% of the global energy consumption, it is necessary to understand energy consumption in peer-to-peer system. In this paper, in this paper we propose a architecture based on the introduction of a p2p proxy. The model is analyzed analytically and numerically to reveal how these factors influence the overall power consumption in both steady state and flash crowd information exchange scenarios. Specifically, our results show that the proxy-based solution can provide up to 50% reduction in the energy consumption and, at the same time, a significant reduction in the average file download time.

The development of IT has contributed a lot to enhancing administrative efficiency. In particular, it enabled administrative agencies to be able to upgrade the effects and efficiency of public services by saving unnecessary time, labor, and equipment that might surely occur in delivering routine services in repetition. As the concept of governance and knowledge-based administration assumes a pivotal value in the 21 century administrative innovation, sharing information among agencies is a key to building effective governance system. However, current extent of sharing information in public agencies is below the level of expectation and thus the need exists for the steps to making information shared more widely and effectively among public agencies. This paper gives a snap shot on the extant status of information sharing among public agencies and seeks ways to facilitate it from the perspective of electrical government.

In the marginal upland areas of East Java, Indonesia, ruminants provide farming households with tradable assets in addition to manure and draught power. Households are interested in acquiring ruminants at an early stage of household development. This paper discusses farmers' access to cattle via sharing arrangements. In these arrangements owners lend animals to other farmers in retum for a share of the offspring or the profits. Livestock owners only entrust cattle to households with prior experience in livestock keeping and sufficient labour. Details of the sharing contracts differ between villages. Changes in cattle numbers and ownership over time are attributed to patterns of the development of village agriculture and the economic development of farming households. Feed shortages in the dry season bring about short-term changes; cattle numbers decline and the proportion of households rearing shared cattle increases. The institution of sharing plays a major role in replenishing herds after periods of severe drought.

In this paper, effects of information sharing in multi-level supply chain management have been studied through simulation. The simulation model consists of a manufacturing company as a center, three suppliers, two logistic centers, and three different retail supply lines of each logistics centers. The mathematical model and the simulation were developed when real-time information sharing occurs and does not occur in supply chain under the assumption that each company applies (s, S) inventory policies. In addition, this paper analyzed the effects of the change of variables related to total costs, which compose of total ordering cost, total transportation cost, total carrying cost and shortage cost that are caused by the change of demand of three different patterns with the way of information sharing.

Recently, consumers are increasingly interested in the sharing economy, which utilizes various resources by sharing unused or under-used products/services with others. This study focuses on Airbnb, a representative sharing economy platform, to identify the success factors of the sharing accommodation services. The key properties of sharing accommodation services are extensively surveyed from extant literature and are classified them into the three important factors (economic, convenience, and trust) that influence the success of room-sharing services. The research data include 1,673 Airbnb hosts who offered accommodations in New York City, USA, in June 2018. The research variables of economic-, convenience-, and trust-related factors are utilized in the empirical analyses. The results of this study show that the number of available facilities, flexibility of refunds, the response rate and time to customer requests, and the status of Super host are positively associated with guest satisfaction from sharing accommodation services. This study bears significant managerial implications by suggesting a set of practical guidelines to participants in sharing accommodation services.

IT service is increasing becoming a critical resource firms have to utilize effectively and efficiently. As the importance of IT service increases, the knowledge sharing between IT service people and users becomes more and more important. In this study, the IT service quality is posited as a critical independent construct that influences knowledge sharing attitude of users which in turn change the knowledge sharing intention. Service satisfaction is placed as a mediator between the quality and attitude to compare direct and indirect effect in the model. Results show that (1) IT service quality influences the knowledge sharing attitude of users directly, and indirectly through service satisfaction, (2) at the same time, however, the direct path from quality to attitude is found to be stronger than the indirect path through satisfaction, and (3) interestingly, satisfaction seems to have no direct effect on intention, but only through the attitude change as can be inferred from the theory of reasoned action. Outcome of this study implies the importance of IT service quality in improving the knowledge sharing activities between users and developers, and interestingly the aim of quality would not be targeted on satisfaction but on attitudinal changes.
