A Study on the Status Quo of Chinese College Students’ Intercultural Communication Competence  [PDF]
Lei Chen, Zhihui Wang
Chinese Studies (ChnStd) , 2018, DOI: 10.4236/chnstd.2018.72014
Abstract: Intercultural encounters have become a fact of daily life in so many cities as well as towns in China, yet English learning is far from enough for cultivating talents with international vision and research on ICC has stepped on agenda. This paper is aimed at investigating the ICC stat quo of Chinese college students. The questionnaire is designed based on Byram’s YOGA including four aspects—intercultural knowledge, intercultural skills, intercultural attitude, and critical intercultural awareness. Research is done with data from the teacher-questionnaire for finding one focus of the four aspects for further research of influencing factors of ICC and with data from the student-questionnaire, on the presumed potential related factors of ICC like major, gender, cultural curriculums, and experience abroad for finding out Chinese college students’ ICC stat quo. 10 (half science and half literary arts) are interviewed to find out how the results come into being. Through the analysis of teacher-questionnaire data, the author gets that intercultural attitude is of the most importance to ICC. The results come out possibly because the acquiring of intercultural awareness, intercultural skills and intercultural knowledge are decided by intercultural attitude.
Analysis of an Ecoepidemiological Model with Prey Refuges
Shufan Wang,Zhihui Ma
Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/371685
Abstract: An ecoepidemiological system with prey refuges and disease in prey is proposed. Bilinear incidence and Holling III functional response are used to model the contact process and the predation process, respectively. We will study the stability behavior of the basic system from a local to a global perspective. Permanence of the considered system is also investigated.
A new concept for cancer therapy: out-competing the aggressor
Thomas S Deisboeck, Zhihui Wang
Cancer Cell International , 2008, DOI: 10.1186/1475-2867-8-19
Abstract: Amongst the distinct hallmarks of cancer are uncontrolled growth and extensive cellular heterogeneity [1]. The 'ecology' concept here is based on the analogy that the host organ serves as 'bio-habitat' for a rapidly expanding heterogeneous tumor cell population, and that the organ's distinct microenvironmental conditions on site only support a certain tumor growth rate and overall tumor mass – prior to the onset of metastasis [2]. If so, one wonders if a tumor could be 'out-competed' for habitat dominance by an autologous cell population that has been engineered to outgrow the tumor cell populations, yet – other than the native cancer cells – can be therapeutically controlled. One can imagine a primary, autografted tumor cell line established from the patient's own tumor (biopsied at the time of operation) that has been genetically engineered to carry an on-off switch that can trigger programmed cell death, or apoptosis, 'on demand'. The corner stone of this innovative concept is to therapeutically skip any number of tumor progression steps by deliberately inserting an autologous cell population that securely outperforms even the most aggressive native cancer cell clone (see Figure 1).The performance requirements for this therapeutic cell population include (i) its proliferation rate must exceed that of the most aggressive native tumor cells; (ii) it should exhibit a reduced apoptotic rate, and, (iii) it must exhibit a high metabolic consumption rate – thereby quickly exhausting the limited resources available to the native tumor cells on site. Assuming that tumor growth is bound by the microenvironmental conditions, we have defined already in [2] the quantitative relationship between the tumor growth rate and an organ's carrying capacity, CC as:Understanding that VTum represents the composite volume of multiple native clones, with distinct proliferative phenotype, and arguing that the therapeutic cell population, PT, must outgrow the native tumor, we revise Eq.

Cancer Dissemination: A Consequence of limited Carrying Capacity?
Thomas S. Deisboeck,Zhihui Wang
Quantitative Biology , 2006,
Abstract: Assuming that there is feedback between an expanding cancer system and its organ-typical microenvironment, we argue here that such local tumor growth is guided by co-existence rather than competition with the surrounding tissue. We then present a novel concept that understands cancer dissemination as a biological mechanism to evade the specific carrying capacity limit of its host organ. This conceptual framework allows us to relate the tumor system's volumetric growth rate to the host organ's functionality-conveying composite infrastructure, and, intriguingly, already provides useful insights into several clinical findings.
The Influence of Job Autonomy on Employee’s Thriving at Work: An Innovative Theoretical Framework  [PDF]
Zhihui Li
Journal of Service Science and Management (JSSM) , 2018, DOI: 10.4236/jssm.2018.116042
Abstract: For enterprises facing a rapidly changing external environment, employee’s thriving at work may be the key to sustained success. After sorting out the current research situation of scholars home and abroad, several shortcomings emerge. In this paper a model of job autonomy affecting employees’ thriving at work through psychological capital is constructed, and the internal mechanism of job autonomy affecting employees’ thriving at work is investigated, which is helpful to grasp the impact of job autonomy on employees’ thriving at work more comprehensively.
Personal customizing exercise with a wearable measurement and control unit
Zhihui Wang, Tohru Kiryu, Naoki Tamura
Journal of NeuroEngineering and Rehabilitation , 2005, DOI: 10.1186/1743-0003-2-14
Abstract: The wearable unit can measure the heart rate and electromyogram signals during exercise performance and output workload control commands to the exercise machines. The workload is continuously tracked with exercise programs set according to personally customized workload patterns and estimation results from the measured biosignals by a fuzzy control method. Exercise programs are adapted by relying on a computer workstation, which communicates with the wearable unit via wireless connections. A prototype of the wearable unit was tested together with an Internet-based cycle ergometer system to demonstrate that it is possible to customize exercise on an individual basis.We tested the wearable unit in nine people to assess its suitability to control cycle ergometer exercise. The results confirmed that the unit could successfully control the ergometer workload and continuously support gradual changes in physical activities.The design of wearable units equipped with measurement and control functions is an important step towards establishing a convenient and continuously supported wellness environment.In rehabilitation engineering and health promotion, personally customized control of machine-based exercise should be introduced to reflect gradual changes in individual physical work capacity [1]. Biosignal-based workload control systems show great promise as an effective approach to regulate exercise levels [2-4]. Generally, exercise levels are adjusted manually for specific exercise machines, in specific places, typically only by physicians with expertise in sports medicine [5-7]. We have developed an Internet-based cycle ergometer exercise system, aimed at providing a personally customized workload control any time in convenient locations [8,9]. In this system, exercise resources including exercise programs and workload patterns are distributed over the Internet and dynamically integrated on the cycle ergometer. Workload patterns provided by clinicians are computer files de

ZhiHui Lu,Ye Wang,Yang Richard Yang
Journal of Communications , 2012, DOI: 10.4304/jcm.7.3.232-245
Abstract: In order to fully utilize the stable edge transmission capability of CDN and the scalable last-mile transmission capability of P2P, while at the same time avoiding ISP-unfriendly policies and unlimited usage of P2P delivery, some researches have begun focusing on CDN-P2P-hybrid architecture and ISP-friendly P2P content delivery technology in recent years. In this paper, we first survey CDN-P2P-hybrid architecture technology, including current industry efforts and academic efforts in this field. Second, we make comparisons between CDN and P2P. And then we explore and analyze main issues, including overlay route hybrid issues, and playing buffer hybrid issues. After that we focus on CDN-P2P-hybrid model analysis and design, we compare the tightly-coupled hybrid model with the loosely-coupled hybrid model, and we propose that there are some main common models which need further study. At last, we analyze the prospective research direction and propose our future work.
An Examination of the Condition of Young Natural Asian White Birch Trees in Manhanshan National Forest Park (Inner Mongolia, China) and Its Early Thinning Technology
Shuankui Wang,Zhihui Zhang,Songqiu Deng,Nan Wang
Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n1p122
Abstract: The goal of the study was to demonstrate forest thinning techniques that should be used beginning in 2011 for the ultimate purpose of timber production by analyzing the stand structure of unthinned natural Asian White Birch forests aged 10-25 years in Manhanshan National Forest Park. The results of the study led to the following three observations: (1) among dominant trees, those with relatively good characteristics should be selected as reserve trees. Any trees obstructing the growth of the reserve trees must be removed as thinned trees. In addition, dominated trees which do not have an impact on the growth of reserve trees are left unthinned to prevent the occurrence of epicormic shoots in reserve trees. (2) The forest at 8-15 year-old should preferably be thinned for the first time. (3) It is desirable to implement thinning frequently at low intensity.

Open Journal of Epidemiology (OJEpi) , 2016, DOI: 10.4236/ojepi.2016.62014
Abstract: Objective: The purpose of this study was to evaluate the difference in alcohol use between urban and rural students of Inner Mongolia Medical University. Methods: A cross-sectional census was conducted on medical students on campus in 2013. We use multivariate logistic regression models to assess the factors associated with alcohol use. We further use chi-square test assess on differences in alcohol use between urban and rural people among significance factors in logistic regression models. Results: The prevalence of alcohol use among students in rural area was higher than that in urban area (p = 0.016). Alcohol use was associated with Gender, monthly expenses, residence, ethnic and faculty. The odds of alcohol use for Mongolia students were 1.139 times higher than that for Han students. The prevalence of alcohol consumption among students from pharmacy or Traditional Chinese Medicine and Mongolian Medicine faculties in rural area was higher than that among student in urban area (p = 0.03; p = 0.001). The prevalence of alcohol use among female students in rural area was higher than that among female students in urban area (p < 0.043). The proportion of alcohol use among students with <600 in rural area was higher than that among students in urban area (p < 0.001). Conclusion: Considering the differences in the prevalence of alcohol use between rural area and urban area, university administrators aiming at students from various regions develop various approaches.
The Impact of Terms of Trade Changes on Economic Welfare: Evidence from China  [PDF]
Jinghua Han, Zhihui Zhang
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.34055
Abstract: Based on the statistics of 1993-2010, this paper analyzes the changing trend and causes of terms of trade in China and studies the overall movement in China’s national wealth by introducing the GDI index under SNA accounting framework. This paper analyzes the relevance between export and real GDP by using the Pearson correlation and partial correlation method, with the final consumption as the economic welfare evaluation index. This paper also presents the change of national wealth by using the weak axiom of revealed preference theory. The result of the study shows that, China’s economic growth is not strongly dependent on exports. It is the export structure of labor intensive products with low price elasticity that mainly lead to the continuously decline of terms of trade in China. However the loss of welfare from the terms of trade’s decline is not enough to offset the benefits of the economic growth. Therefore there is no probability of “Immiserizing Growth” in China’s foreign trade.
