Abstract

Recently, e-commerce has enjoyed the appearance of many novel opportunities created as a result of the increasing growth of social networks. Social commerce (s-commerce), an offspring of e-commerce, interconnects users and helps with the commerce process facilitated by social networks as well as other media. Uncertainty and trust are always an issue in any type of commerce and especially in s-commerce where, due to its nature, a higher level of risk and uncertainty exists. Despite the history for trust in virtual commercial transactions, there are a limited number of researches on the topic; and the current shift towards commerce in virtual communities and networks begs further attention. Therefore, in this paper, by scrutinizing the available literature on the topic, the affecting factors on trust in scommerce are identified and introduced. Among the reviewed papers, 7 papers matched the criteria, and overall, 19 factors were extracted. Firm size, trust disposition, information quality, and familiarity with other members were among the most cited factors in the literature.

Abstract

Social network analysis emerged as an important research topic in sociology decades ago, and it has also attracted scientists from various fields of study like psychology, anthropology, geography and economics. In recent years, a significant number of researches has been conducted on using social network analysis to design e-commerce recommender systems. Most of the current recommender systems are designed for B2C e-commerce websites. This paper focuses on building a recommendation algorithm for C2C e-commerce business model by considering special features of C2C e-commerce websites. In this paper, we consider users and their transactions as a network; by this mapping, link prediction technique which is an important task in social network analysis could be used to build the recommender system. The proposed tow-level recommendation algorithm, rather than topology of the network, uses nodes features like: category of items, ratings of users, and reputation of sellers. The results show that the proposed model can be used to predict a portion of future trades between users in a C2C commercial network., Comment: 7 pages, 5 figures

Abstract

The application of compound distributions has recently increased due to the flexibility in fitting actual data in various fields such as economics, insurance, etc. Poisson-half-logistic distribution is one of these distributions with an increasing-constant hazard rate that can be used in parallel systems and complementary risk models. Because of the complexity of the form of this distribution, it is not possible to obtain classical parameter estimates (such as MLE) by the analytical method for the location and scale parameters. We present a simple way of deriving explicit estimators by approximating the likelihood equations appropriately. This paper presents the AMLE (Approximate Maximum Likelihood Estimator) method to estimate the location and scale parameters. Using simulation, we show that this method is as efficient as the maximum likelihood estimators (MLEs). We obtain the variance of estimators from the inverse of the observed Fisher information matrix, and we see that when sample size increases, bias and variance of these estimators, and hence MSEs of parameters, decrease. Some pivotal quantities are proposed for finding confidence intervals for location and scale parameters based on asymptotic normality. From the coverage probability, the MLEs do not work well, especially for the small sample sizes; thus, simulated percentiles based on the Monte Carlo method are used to improve the coverage probability. Finally, we present a numerical example to illustrate the methods of inference developed here. [ABSTRACT FROM AUTHOR]

Abstract

Process mining in the context of information systems, which consists of information flows, has been one of the major research areas in the past decade. One of the most common objectives of process mining is the automated business process discovery. There are many challenges in the business process discovery, such as spaghetti models, same-name activities, and discovering loop structures. The researchers have presented a variety of methods that focus on one or more challenges. Due to the importance of commercial systems and the diversity of flows in them, in this research, the process mining problem in the context of social commerce systems is studied. Moreover, the research objective is to present a new method for commercial process discovery that has not been considered before. The proposed method is based on network analysis methods, multi-layered networks (networks with heterogeneous relations), and attributed networks. The results obtained from the proposed method are more precise and more comfortable to understand than the previous ones.

Abstract

Globalization is a term that has become popular since the mid-1980s, which means the collapse of the borders and its transnational globalization in terms of economic, cultural, political and social dimensions. The process is the transformation of local structures into the world. "Globalization" is a multidimensional phenomenon whose effects can be extended to social, economic, political, legal, cultural, military, and technological activities, as well as social activities, such as the environment. Therefore, globalization can be examined from a variety of dimensions. Economic scholars have defined globalization in different ways, and they have looked at each and every particular point of view. Globalization, its dimensions and scope are so wide-spread that it has affected all aspects of human life, to which some scholars have called it the greatest event of human history. As in the past few decades, in the light of the development of the electronic communications revolution, the concept of distance and space has been unthinkable. Globalization has emerged in its present form since the collapse of communism, the bipolar system, and the end of the Cold War. In fact, globalization refers to a process in which the free flow of thought, man, goods, services, and capital in the world can and can be realized. The present study was to understand the importance and challenges of globalization and the threats against the Islamic Republic of Iran to analyze this phenomenon and Develop and submit to the demands of the 21st century, the country's main strategies in dealing with globalization of culture, society, economy and politics is discussed. The results show that the strategies for dealing with globalization, It can be said that the implementation of strategies and opportunities that it creates For the protection of cultural and social identity important part of our identity is a need to strengthen and enhance the level of cultural, social and economic Gmarym efforts Protec

Abstract

Background: Previous research of patients with multiple sclerosis (MS) focused prevalently on fatigue, depression, and cognitive dysfunction during the clinical course. By contrast, research on the longer-term characteristics of physical activity (PA), psychological functioning, and sleep problems is scarce. The aims of the present study were therefore to examine changes in PA, mental toughness (MT) as a proxy of psychological functioning, and sleep disturbances over a 2-year period of time after disease onset. Methods: A total of 18 patients with diagnosed MS (mean age: M = 34.29 years) took part in this longitudinal study. First, 1-4 weeks after the first symptoms, a neurologist diagnosed the MS. Second, they completed a series of questionnaires covering socio-demographic data, PA, MT, and sleep disturbances. Third, the same questionnaires were completed again 2 years later (follow-up). Last, a neurologist assessed the degree of disability with the Expanded Disability Status Scale (EDSS). Results: Two years after MS onset, patients had lower levels of vigorous PA, but no statistically significant changes in moderate PA were observed. Further, walking time increased and sedentary time decreased. Patients with sleep disturbances at disease onset also reported poor sleep 2 years later. MT scores remained stable over time. EDSS scores worsened, though, change in EDSS was not associated with PA, MT, or sleep. Conclusions: Two years after disease onset, patients withMS reported similarMT levels and sleep disturbances. PA shifted fromvigorous PA toward walking and a less sedentary lifestyle, while moderate PA remained unchanged. The pattern of results of the present pilot study suggests that at the early stage of the MS course, there is no obstacle for being physically active, nor did sleep and MT as a proxy of psychological functioning decrease in a substantial way.
