Recurrent neural network has been widely applied to many sequential tagging tasks such as natural language process and time series analysis, and it has been proved that RNN works well in those areas. In this paper, we propose using RNN with long short-term memory units for server load and performance prediction. Classical methods for performance prediction focus on building relation between performance and time domain, which makes a lot of unrealistic hypotheses. Our model is built based on events, which is (...) the root cause of server performance. We predict the performance of the servers using RNN-LSTM by analyzing the log of servers in data center which contains user’s access sequence. Previous work for workload prediction could not generate detailed simulated workload, which is useful in testing the working condition of servers. Our method provides a new way to reproduce user request sequence to solve this problem by using RNN-LSTM. Experiment result shows that our models get a good performance in generating load and predicting performance on the data set which has been logged in online service. We did experiments with nginx web server and mysql database server, and our methods can been easily applied to other servers in data center. (shrink)

A qualitative study was conducted with 48 Chinese counselors and psychotherapists who were interviewed in 2006 and an independent sample of 50 participants who responded to a survey in 2014. This study aims to explore how the new emerging expansion of mental health practice is related to issues and challenges of dual role relationship and how the well-engrained values and social characteristics of Chinese culture influences perceptions and resolution of ethical dilemmas. The participants identified similar dual relationships in 2006 and (...) 2014: Incidental boundary crossings, a sexual or romantic relationship, a dual social relationship, and a professional dual relationship were the most frequently reported types of dual relationships encountered by Chinese practitioners, and the socioeconomic and cultural context and the development trajectory of counseling and psychotherapy in China play a significant role in shaping practitioners’ behaviors. The comparison of the data in 2006 and 2014 indicated that practitioners in psychotherapy and counseling have an improved awareness and understanding of ethical issues, evidenced by the decreasing cases of romantic and sexual relationships and increasing cases of social dual relationships influenced by the interrelatedness of traditional Chinese culture.

With the popularity of computer-based testing, it is easier to collect item response times in psychological and educational assessments. RTs can provide an important source of information for respondents and tests. To make full use of RTs, the researchers have invested substantial effort in developing statistical models of RTs. Most of the proposed models posit a unidimensional latent speed to account for RTs in tests. In psychological and educational tests, many tests are multidimensional, either deliberately or inadvertently. There may be (...) general effects in between-item multidimensional tests. However, currently there exists no RT model that considers the general effects to analyze between-item multidimensional test RT data. Also, there is no joint hierarchical model that integrates RT and response accuracy for evaluating the general effects of between-item multidimensional tests. Therefore, a bi-factor joint hierarchical model using between-item multidimensional test is proposed in this study. The simulation indicated that the Hamiltonian Monte Carlo algorithm works well in parameter recovery. Meanwhile, the information criteria showed that the bi-factor hierarchical model is the best fit model. This means that it is necessary to take into consideration the general effects and the multidimensionality of the RT in between-item multidimensional tests. (shrink)

Chief executive officer tenacity plays an important role in corporate entrepreneurial activity. However, much less is known about its impact on employee intrapreneurship. Drawing from social information processing theory and upper echelons theory, this article examines the hitherto unexplored nexus between CEO tenacity and employee intrapreneurship, as well as the mediating role of corporate social responsibility. Quantitative data were collected through a survey administered to 294 employees working in different sectors that engage in CSR activities in China. Data analysis was (...) performed using hierarchical regression method through Stata 16.0. It was found that CEO tenacity was significantly positively correlated with employee strategic renewal behavior and employee venture behavior. The positive correlation between CEO tenacity and CSR was also significant. Besides, CSR partially mediated the relationship between CEO tenacity and employee strategic renewal behavior or employee venture behavior. This study extends research on CEO tenacity, CSR, or employee intrapreneurial behavior by providing a better understanding of the direct effects of CEO tenacity on employee intrapreneurial behavior and CSR. From the perspective of cross-fertilization between psychology and management, this study establishes the interface role of CSR by elucidating the intrinsic mechanism of CEOs with high levels of tenacity to stimulate employee intrapreneurial behavior through CSR.

本書希望為人文社會科學方法提供一種較為系統的討論。在本書看來，盡管人文社會科學與自然科學在研究對象上存在差異，但都是人類的認識活動，它們所包含的認識過程存在相似性，可從中重建一個共同的基本認識過程。這 一基本認識過程包含諸多前后相繼的環節，而不同認識環節有不同的方法。 本書探討不同認識環節中各種方法的特點、價值與局限，以期較為全面地理解人文社會科學方法。 黃正華,男,1970年3月生,湖南益陽人,武漢大學理學碩士,南京大學科學哲學博士,復旦大學政治哲學博士后,副教授。.

As competition over peer status becomes intense during adolescence, some adolescents develop insecure feelings regarding their social standing among their peers. These adolescents sometimes use aggression to defend or promote their status. The aim of this study was to examine the relationships among social status insecurity, callous-unemotional traits, and popularity-motivated aggression and prosocial behaviors among adolescents, while controlling for gender. Another purpose was to examine the potential moderating role of CU traits in these relationships. Participants were 1,047 in the 7th (...) or 8th grades from a large Midwestern city. They completed questionnaires on social status insecurity, CU traits, and popularity-motivated relational aggression, physical aggression, cyberaggression, and prosocial behaviors. A structural regression model was conducted, with gender as a covariate. The model had adequate fit. Social status insecurity was associated positively with callousness, unemotional, and popularity-motivated aggression and related negatively to popularity-motivated prosocial behaviors. High social status insecurity was related to greater popularity-motivated aggression when adolescents had high callousness traits. The findings have implications for understanding the individual characteristics associated with social status insecurity. (shrink)

Earthquake is a kind of natural disaster, which will have a great impact on the building structure. In the vibration control field of building structures, the timeliness of system stability is extremely important. In traditional control methods, the timeliness is not paid enough attention for systems with uncertain seismic waves. For setting this problem, fuzzy adaptive compensation control for uncertain building structural systems by sliding-mode technology is proposed. It is combined with fuzzy adaptive control and sliding-mode control to ensure that (...) the system can be stable with satisfied timeliness. Also, saturation function is used to ensure the feasible physical implementation of the control system. Compared with the traditional LQR control, the simulation results showed that the proposed method can make the system reach a stable state with rapid convergence performance and has a feasible physical implementation.
