Li-Se Yang, Hsieh-Hua Yang, Hsiu-Tzu Chen, Mei-Fang Chang, Yu-Fen Chiu, Ya-Wen Chou, Yen-Chi Cheng
Health (Health) , 2012, DOI: 10.4236/health.2012.411167
Abstract: We suggest that employees’ job satisfaction has relationship to friendship network other than professional commitment, and argue that friendship network in the same ward and across wards will have different effects on employees’ job satisfaction. A cross-sectional survey design utilizing questionnaires was selected to fulfill the research objectives. All of the 405 nurses in the En Chou Kong Hospital were surveyed. Three hundred and three nurses completed the questionnaire representing a response rate of 74.8%. The instruments included friendship network nomination, professional commitment scale, and nurses’ job satisfaction scale (NJSS). The regression model of job satisfaction was constructed, using friendship network variables in the ward and across wards and professional commitment as independent variables. R square for each model is 0.22-0.36 for the four dimensions of job satisfaction. Professional commitment is the robust predictor. The efficiency of friendship network in the ward is a good predictor, while it is negative related to satisfaction of work load. Further, the indegree in the ward is negative related to work load. Implication was discussed.

Molecules , 2012, DOI: 10.3390/molecules17078056
Abstract: Many thermal runaway incidents have been caused by organic peroxides due to the peroxy group, –O–O–, which is essentially unstable and active. Lauroyl peroxide (LPO) is also sensitive to thermal sources and is incompatible with many materials, such as acids, bases, metals, and ions. From the thermal decomposition reaction of various concentrations of nitric acid (HNO3) (from lower to higher concentrations) with LPO, experimental data were obtained as to its exothermic onset temperature (T0), heat of decomposition (ΔHd), isothermal time to maximum rate (TMRiso), and other safety parameters exclusively for loss prevention of runaway reactions and thermal explosions. As a novel finding, LPO mixed with HNO3 can produce the detonation product of 1-nitrododecane. We used differential scanning calorimetry (DSC), thermal activity monitor III (TAM III), and gas chromatography/mass spectrometer (GC/MS) analyses of the reactivity for LPO and itself mixed with HNO3 to corroborate the decomposition reactions and reaction mechanisms in these investigations.
The Development of Trait Inference at Behavioral and Psychological Levels

心理学报 , 2009,
Abstract: Personality traits are stable, internal characteristics that enable people to summarize, explain, and predict behavior. People often make inference about behavior based on personality traits. It is suggested that trait inference may be made at two different levels: behavioral and psychological. During the past three decades, researchers have been interested in children's understanding of traits, and a large amount of research has been conducted to investigate the development of trait inference. Before the 1990s, the majority of studies focused on children's trait inference at the behavioral level by using behavior predictions. After the 1990s, researchers studied the psychological cause of behavioral regularity by examining children's theory of mind and internal state predictions. However, less attention has been paid to direct comparisons of the two levels of children's trait inference and the rules they use to make behavioral and psychological predictions. The aim of the present study was to investigate the development of trait inference at the two levels and the use of different rules that children used in trait inference.The participants in the study included 160 children at 4 to 12 years and 32 undergraduate students. Trait inference was measured through behavioral and emotional predictions, and the information was collected about the rules children used to make trait inference.The major results are as follows. First, children at least from age 4 were capable of making trait inference at the behavioral level, and from age 5 capable of making trait inference at the psychological level. Chidren's trait inferences at both levels matured at 10 years. Second, trait inference at the psychological level fell behind trait inference at the behavioral level at ages 4 and 5, and there were no significant differences between the two types of inferences at age 7. Third, children used a conceptual similarity rule rather than a simple situation-matching rule to predict behavior. Finally, children at 4 years did not employ a simple valence rule to make cross-trait category behavioral predictions, whereas children at 5, 7, 10 and 12-years and adults showed evidences of using this rule in a clearly discriminating way.These findings indicate the developmental trend of trait inference at the behavioral and psychological levels in Chinese children. The study also provides some new information about the strategies that children might use to make behavioral predictions.
Shared Equity Policy in Joint Ventures for Host Countries
Mei-Fang Chung
Economic Analysis and Policy , 2011,
Abstract: This paper provides a game model for examining the host overseas investment policy and MNEs equity strategy in international joint ventures. This paper refines previous Chen & Chung’s (2008) results and considers the host policy about MNEs’ joint-venture. This paper shows foreign firms increase their technology transfer incentive because less competition from the joint-venture partner when a foreign firm holds lower shares. And the holding shares of foreign firms must be not smaller than 50 percent. The host welfare increases with foreign firms’ minority equity. The equity conflict exists in the higher technology spillover and transfer cost cases. Hence, the host governments always impose investment restrictions on MNEs in the Developing countries. Otherwise, it has more loose policy in the Developed countries.

无机材料学报 , 2011, DOI: 10.3724/sp.j.1077.2011.00387
Abstract: CuO―doped SrFe0.9Sn0.1O3― δ (CSFS) thick―film negative temperature coefficient (NTC) thermistors ( 20mol%, 30mol%, 40mol%, 50mol% ) were prepared by the screen printing method. The microstructures and electrical prop erties of CSFS thick films were determined. With the increase of CuO content, the surface morphology of thick films becomes denser. The room―temperature resistance values gradually decreases to about 0.46 M Ω and the thermistor― constant values are basically constant at around 3300 K. After the addition of CuO, SrFe0.9Sn0.1O3― δ is decomposed into various SrFe1― xSn xO3― δ ( 0.1< x<1 ) phases. By two― RQ series equivalent circuit model, impedance characteristics of the thick film containing 40mol% CuO content are investigated over the measured temperature range of 25–250 It is found that the total thick―film resistance is mainly attributed to the contribution of grain and grain boundary resistances, both of which show the typical NTC thermistor characteristics. Furthermore, the complete match of peak frequencies between the imaginary parts of impedance and electric modulus suggests that delocalized conduction is the main conduction mechanism in the thick―film NTC thermistors.

Abstract: Objective: To study the mechanism of Huoxue Qianyang Granule (HXQYG), a traditional Chinese compound medicine, in revising the left ventricular hypertrophy of hypertension. Methods: Spontaneous hypertension rats (SHR) were randomly divided into seven groups: untreated group, Songling Xuemaikang (SLXMK)-treated group, captopril-treated group, high-, medium- and low-dose HXQYG-treated groups, and normal control group. The systolic blood pressure (SBP) and left ventricular mass index (LVMI) were measured. The content of angiotensin Ⅱ (AngⅡ) in left ventricular tissue was determined by radioimmunoassay. The expressions of angiotensin converting enzyme (ACE) protein and mRNA in left ventricular tissue were analyzed separately by immunohistochemical method and RT-PCR. Results: (1) SBP and LVMI were higher in the untreated group than those in the normal control group, and they were lower in the high- and medium-dose HXQYG-treated groups than those in the untreated group, but higher than those in the captopril-treated group, and without significant difference as compared to those in the SLXMK-treated group. (2) The content of AngⅡ and expressions of ACE protein and mRNA in the left ventricular tissue in the untreated group were higher than those in the normal control group, and they were lower in the HXQYG-treated groups than those in the untreated group, but higher than those in the captopril-treated group, and without significant difference as compared to those in the SLXMK-treated group. Conclusion: HXQYG can reverse the left ventricular hypertrophy of SHR, which may be due to decreasing the amount of AngⅡ and expressions of ACE protein and mRNA in the left ventricular tissue.

Abstract: Using photoluminescence (PL) and Raman scattering (RS), the MBE grown Hg 1- x Cd x Te ( x =0.325) epilayers were studied. The PL measurement shows a strong near band emission peak with a FWHM of 5meV, which indicates high crystal quality obtained. Three peaks, the relatively strong HgTe like TO mode at 119cm -1 and HgTe like LO at 139cm -1 and a weak LA mode at 93cm -1 , were observed on RS spectra. The weak peak at 93cm -1 has not been reported previously. The assignment of the peak is based on the comparison with the result of far infrared transmittance spectra(FIT).

The Successful Development Strategy for E-Shops from the Perspectives of Value
Te-King Chien,Mei-Fang Wang
International Journal of Electronic Business Management , 2006,
Abstract: Under fast development of the Internet, e-Shops have become an important marketing channel. Despite the growth of Internet surfers, the population with experiences of shopping online has not grown to a significant level. In addition to the incomplete online shopping environment and security issues, the insufficient understanding of most enterprises about how to manage an e-Shop is also the main reason. To provide a seasonable solution to this issue, this study would (1) derive 4 constructs, 16 categories, and 68 key success factors via literature reviews, expert interviews, Focus Group, and Delphi method; (2) establish an operation value system of e-Shops as the basis of assessing the difference in key success factors; (3) integrate the value system and the concept of Kano model to develop Kano-value model, so as to get hold of the properties and category of each key factor; (4) apply FAHP (Fuzzy Analytic Hierarchy Process) to present the importance ranking of the 4 constructs and 16 categories as the basis for the staged development of enterprises; and finally (5) according to the ranking, establish the successful development strategy for e-Shops. It was expected that the research results would serve as a reference for more accurate systemization of e-Shops in the process of development and reduce the exploration time and possibility of failure in the process of test and trial.
