He cannot find identification with himself in the hostile city which does not provide any chance for him to be a better man. What is more, the absence of community in the city makes his strife become hopeless, and drives him into the state of alienation. Opposing against the brutal surroundings, he turns to violent behavior for the spiritual rescue. Yet, since violence derives from a sense of impotence, it cannot protect him from being alienated. Bom in a lower class, however hard he tries, Jules becomes powerless in front of the relentless society and doomed to be a tragedy展开更多

Through a qualitative methodology, the authors interpreted some of the arguments that explain and/or justify certain practices in relation to doubled production, authorship, and coauthorship of academic products. In this paper, the authors present and analyze the results that they obtained after reviewing documents produced by professors and students of six postgraduate programs that are taught in two Mexican public universities. At the same time, the authors examine some of the practices that take place within said programs, given the institutional demands of improving finished studies efficiency. One of the hypotheses of this work is the demands that are imposed by external evaluations of academic processes on professors and their programs in order to reach desirable rates with the purpose of maintaining or increasing the levels of productivity, gives way to certain practices that must be analyzed. This work's theoretic framework is constituted by the contributions of career sociology and professional ethics.展开更多

The serious consequences of this phenomenon become increasingly prominent.it not only damaged the justice of labor market, but also violated the staffs interest. Various factors influence enterprise to participate in social insurance behavior .Human capital is the impact of insurance companies. This paper is mainly focusing on the theory analysis of different human capital participating behavior of enterprises. From the perspective of human capital, using the cost-benefit theory and rational choice theory in economics to explore participating behavior, enterprise employees of different human capital differences in attitude to attend social insurance. No matter enterprises with higher or lower human capital, enterprises and employees choose to participate in social insurance act consistently. But, it can improve participate of low human capital enterprise behavior when payment rate reduced. So, it is suggested that establishing a lower level of social insurance system is helpful to expand coverage, it can through e^tahllgh the sunnlementarv insurance system meet the needs of more people.展开更多

This is the reason of numerous definitions of this term included in the first part of the paper, which varies according to the aspect of the analysis, analyzed marketing unit, tourism product, geographical unit, region, destination, or entities that offer an acceptable integrated product a package by specific indicators for comparison of elements of competitiveness. The first part of the article theoretically emphasizes the distinction in defining the concept of competitiveness from various aspects of the analyzed market subjects (different features and facilities provided), and from those aspects of their specific business relationship in the market. Special contribution to the study of competitiveness is contained in the second part of the paper that analyzes the existing situation of intermediation in the European tourism market. This research is based on using the data of descriptive statistics and the secondary research which gives insights into the business of travel agencies, using the data such as number of employees, annual personnel costs, and the average annual cost per person employed in travel agencies in some European countries. The changes in the environment, and the competition initiate a need for an analysis of the internal environment, travel agencies' tasks, and their organizational structure. Also, the results conducted research on a sample of 500 travel agencies in 20 European countries indicate the dominance of quality service, price, and value for money as key factors of demand for achieving the competitiveness. It indicates new trends focused on needs for more specific--integrated tourist products that ensure the quality of service, value for money, and for the time that tourists invest in their obtaining.展开更多

The force, like a kind of gravitation, is modeled based on the movement state and visual field of the pedestrian, and is added to the classical SFM. The modified model is presented to study the impact of following behavior on the process of lane formation, the conflict, the number of lanes formed, and the traffic efficiency in the simulations. Simulation results show that the following behavior has a significant effect on the phenomenon of lane formation and the traffic efficiency.展开更多

Interactions among pedestrians are considered as the result of forces within a certain neighbourhood. Unlike the social force model,the forces here,as in Newtonian physics,are proportional to the inverse of the square of the distance. Despite the notion of neighbourhood and the underlying grid,this model differs from the existing cellular automaton(CA) models in that the pedestrians are treated as individuals. Bresenham's algorithm for line rastering is applied in the step calculation.展开更多

In our model, actors update their opinions under the interplay of social influence and self- affirmation, which leads to rich dynamical behaviors on online social networks. We find that the opinion leading to the consensus features an advantage of the initially weighted fraction based on actors' strength over the other, instead of the population. For the role of specific actors, the consensus converges towards the opinion that a small fraction of high-strength actors hold, and individual diversity of self-amrmation slows down the ordering process of consensus. These indicate that high-strength actors play an essential role in opinion formation with strong social influence as well as high persistence. Further investigations show that the initial fraction of high-strength actors to dominate the evolution depends on the heterogeneity of the strength distribution, and less high-strength actors are needed in the case of a smaller exponent of power-law distribution of actors' strength. Our study provides deep insights into the role of social influence and self-affirmation on opinion formation on online social networks.展开更多
