Sexual-Moral Attitudes of Chinese College Students: Two Moral Criteria Systems?  [PDF]
Yongkang Zhou, Weixi Zeng, Yalin Hu
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.52018
Abstract:

The aim of this study is to develop a valid scale to measure the construct of the sexual-moral attitudes of Chinese college students. Based on open questionnaire investigation, in-depth interviews, exploratory factor analysis and confirmatory factor analysis, the 20-item Sexual-Moral Attitudes Scale (SMAS) was developed and emerged with good psychometric properties. The multi-hierarchy and multi-dimension construct was confirmed. It can be concluded that contemporary Chinese college students has two moral criteria systems to regulate their sexual behaviors. The first one is the Basic Sexual-Moral Principles, which includes two first-hierarchy dimensions as Sense of Responsibility and Sense of Ethics; the second one is Strict Sexual-Moral Principles, which includes three first-hierarchy dimensions as Being in Love, Chastity and Fidelity.

The Relationship among Role Conflict, Role Ambiguity, Role Overload and Job Stress of Chinese Middle-Level Cadres  [PDF]

Chinese Studies (ChnStd) , 2014, DOI: 10.4236/chnstd.2014.31003
Abstract: This research aims to explore the relationship among role conflict, role ambiguity, role overload and job stress of middle-level cadres in Chinese local government. Through a questionnaire survey of 220 cadres, the results showed that time pressure was significantly correlated with role conflict and role overload; job anxiety and job stress were significantly and positively correlated with role ambiguity, role conflict and role overload; role ambiguity had a significant and positive effect on job anxiety and job stress; role conflict and role overload had a significant and positive effect on time stress, job anxiety and job stress.

Noise Simulation Analysis of a Variable Displacement External Gear Pump and Unloading Groove Optimization  [PDF]
Yongkang Zhou, Wenwu Li, Dongpo Yang
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1105030
Abstract:
The oil pump is an important part of vehicle engine, whose noise and vibration characteristics affect the engine performance significantly. The noises generat-ed by both the pressure and flow fluctuations are the main contributors to the oil pump noise. In this paper, noise analysis of an external gear pump is carried out by using the computational fluid dynamics (CFD) method and The Lighthill’s acoustic analogy (LAA) algorithm. The fluid pressure and velocity distributions of the flowfield are firstly calculated by using a CFD model. The noises generated by flowfield are simulated and their sound pressure spectra are obtained by using an LAA-based finite element model. By analyzing the phenomenon of oil trapping, the optimum design of unloading groove is put forward, and then the simulation analysis is carried out. According to the finite element model, the noise level of gear pump is reduced and the effect of noise reduction is achieved. The technique presented in this paper can be regarded as a useful tool for optimization design of gear pumps in vehicle engineering.
SHRIMP zircon U-Pb dating for subduction-related granitic rocks in the northern part of east Jungaar, Xinjiang
Zhaochong Zhang,Shenghao Yan,Bailin Chen,Gang Zhou,Yongkang He,Fengmei Chai,Lixin He,Yusheng Wan
Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-008-0952-7
Abstract: SHRIMP U-Pb zircon dating on the Xileketehalasu granodiorite porphyry and Kalasayi monodiorite porphyry that intrude middle Devonian Beitashan Formation at the north part of east Junggar region shows that they were formed at 381 ±6 Ma and 376±10 Ma respectively. They are interpreted as subduction-related granitic rocks, which is the first report that the isotopic ages for the granitic rocks range from 350 to 390 Ma. Another determined age for the Kalasayi monodiorite porphyry is 408±9 Ma, representing the age of underlain Lower Devonian volcanic rocks. Thus, the U-Pb dates suggest that the northeastward subduction of Junggar ocean from southwest occurred at 408 to 376 Ma (the real interval may be larger). Because the ore-bearing porphyry intruded following the formation of the volcanic rocks of middle Devonian Beitashan Formation, their tectonic setting is similar to the Andes Mountains that hosts world-class porphyry copper deposits, and the researched area could be regarded as a potential area for prospecting large porphyry copper deposits.

Validité, fiabilité et difficulté : une analyse du TFS8 en Chine
WANG Yongkang
Synergies Chine , 2012,
Abstract: Le test est étroitement lié à l’évaluation dans de nombreux domaines dont l’éducation en particulier. à partir de la théorie de test de langues, une analyse sur le TFS8 en Chine sera effectuée dans cet article. Sa validité, sa fiabilité et sa difficulté seront notre principale préoccupation au cours de l’analyse. Nous voulons ainsi en étudier les avantages et les inconvénients tout en donnant quelques conseils dans l’optique de son amélioration
Collision Detection and the Design of Fair and Stable MAC Scheme for Wireless Ad Hoc Networks  [PDF]
Yongkang Xiao, Rong Xiao, Bo Sun
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2065
Abstract: Fairness and stability guarantee among TCP flows is very stubborn in wireless ad hoc networks. There is not a MAC protocol that can fulfill this acquirement until now. In this paper, we firstly reveal the in-depth causes of the severe TCP unfairness and instability problems in IEEE 802.11-based multihop networks. Then we utilize the collision detection mechanism of the IEEE 802.11 protocol which is often ignored by most of the people to design a novel collision detection mechanism-based MAC (CDMB-MAC) scheme to solve the short-term and long-term fairness and stability issues while providing a good aggregate throughput in many topologies.
Methods for Statistical Inference of Triangle Taste Tests Data and Their Applications  [PDF]
Yongkang Xu, Xingxu Li, Jiachun Xie
Open Journal of Business and Management (OJBM) , 2014, DOI: 10.4236/ojbm.2014.22011
Abstract:

This paper designs methods of product differences testing and preference testing by using triangle taste tests data. Binomial distribution theory and hypothesis test method are employed since that the existing statistical inference methods of triangle taste tests methods for sensory and quality analysis of cigarette products have some shortcomings. Finally, two case studies are provided, which have very important managerial implication to cigarette enterprises.
