This hierarchical model summarizes the action contents with different spatio-temporal domains according to the properties of human body movement.First,the temporal gradient combined with the constraint of coherent motion pattern is utilized to extract stable and dense motion features that are viewed as point features,then the mean-shift clustering algorithm with the adaptive scale kernel is used to label these features.After pooling the features with the same label to generate part-based representation,the visual word responses within one large scale volume are collected as video object representation.On the benchmark KTH（Kungliga Tekniska H？gskolan）and UCF （University of Central Florida）-sports action datasets,the experimental results show that the proposed method enhances the representative and discriminative power of action features, and improves recognition rates.Compared with other related literature,the proposed method obtains superior performance.展开更多

The present study aims to find the effect of cultural orientatiotr---like individualism or collectivism on a person＇s organizational citizenship behavior （OCB） There are many studies related to collectivism and organization citizenship behavior as well as organization commitment and OCB. But most of these studies were done in a western context and is done years back. The present generation of UAE having undergone studies in management which is highly dominated by western philosophies and due to their interaction with diverse nationalities have evolved in their behavior. At this point it is necessary to investigate whether there is any shift in their behavior pattems based on collectivism. Career commitment has grown among UAE nationals in recent years due to high level of commitment from the government towards education and employment. Since OCB is more of an altruistic tendency within an individual, the study looks into the cultural difference within an individual like individualism or collectivism and its relationship with a person＇s OCB level among the employees in UAE. Career commitment is taken as a another variable. The study has made some interesting findings which show a shift from the previous studies that show a direct relationship using correlation analysis, between collectivism and organization citizenship behavior. The study found that there is no relationship between individualism or collectivism and organization citizenship behavior, but there is some relationship between career commitment and organization citizenship behavior factor loyal boosterism.展开更多

UML is a widely used modeling standard, yet it is very difficult to apply it to system verification and testing directly for its imprecise semantics. After analyzing the expression ability of the two models, several transforma- tion rules are defined and each step of transformation is described in detail, after that, the approach is illustrated with an example. The paper provides a method for acquiring interface automata and lays the foundation for related research.展开更多

In this context, efforts toward making employees＇ knowledge, which is an indispensable value for organizations, accessible and efforts to make it available for work processes and social relations extend new behavioral patterns. Organizational citizenship behavior is an example of such patterns. This paper attempts to explain and discuss interactions between organizational citizenship behavior and knowledge sharing, which is reasoned to have a defining role over it, and to draw attention on the issue. Organizational knowledge sharing, the factors influential on it, and the relationships between the antecedents of organizational citizenship behavior and knowledge sharing are being dwelled upon conceptually展开更多

We characterize the system by studying how to perform the transition, which is now topology-dependent, from the active state to that with no activity. This could be a naive model for the wakening and sleeping of a brain-like system, i.e., a multi-component system with two different dynamical behavior.展开更多

The participants were new nurses, preceptors of new nurses, administrators, patients and members of the patients＇ family cared by new nurses. The research instruments were： （1） five questionnaires toward program suitability, knowledge, attitude, caring expression, and result to organization. The mean, standard deviation and dependent sample t-test were used for data analysis; （2） guidelines for focus group discussion and semi-structural questionnaire analyzed by content analysis. The study revealed that： （1） the mean of suitability was at the very high level （X = 4.49, SD. = .30）; （2） the knowledge and attitude after training were significantly higher than before training at .000 level, [t =-21.65, p = .000 and t = -19.30, p = .000）; {3} caring behavior after training was significantly higher than before training at the .000 level; and {4} the result of the program was at the high level { X = 4.25, SD. = .17}, related to the result of semi-structured interview and focus group discussion. These evaluation research finding suggested that administrators can use for improving the preparation of any project and apply to evaluate other training programs, developing human resource system.展开更多
