Career Success of Knowledge workers: The Effects of Perceived Organizational Support and Person-Job Fit  [PDF]
Yu Chen
iBusiness (IB) , 2010, DOI: 10.4236/ib.2010.24051
Abstract: The purpose of this paper is to review relevant literatures on career success and develop a theoretical framework and testable propositions concerning how person-job ?t and perceived organizational support relate to career success.
A Study on the Career Commitment Factor Structure of Knowledge Staff  [PDF]
Yu CHEN
iBusiness (IB) , 2009, DOI: 10.4236/ib.2009.11004
Abstract: This paper studied the knowledge staff’s career commitment factor structure. The datas from 123 knowledge employees were examined by factor analysis, descriptive analysis and so on. The results showed: a)The career commitment of knowledge staff consists of four dimensions: affective commitment, continuance commitment, career resilience and career loyalty. b)All the reliability and validity indexes of the modified questionnaire are satisfactory.
Chinese Knowledge Employees’ Career Values, Perceived Organizational Support and Career Success  [PDF]
Chen Yu
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.33036
Abstract: Purpose: the purpose of this study was to investigate the effects of career values and perceived organizational support on career success and to examine what career values are. Design/Methodology: survey data were collected from a sample of 151 Chinese knowledge employees. Career success was measured by subjective, that is career satisfaction. Findings: 1) There were three dimensions of career values, and they are self-achievement, factor hygienic factor and prestige factor. 2) Career values and organizational support can predict career success. Implications: knowledge of the antecedents to career success should provide certain advantages to organizations attempting to select and motivate employees. Originality/value: this paper makes a valuable contribution to career success literatures by being one of the ?rst to examine the effect of career values on career satisfaction.
Large renal carbuncle mimicking intra-abdominal neoplasm on Ga-67 scintigraphy: A case of fever of unknown origin  [PDF]
Yu-Hung Chen
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.23059
Abstract:

Fever of unknown origin is still a medical challenge. 67Ga single photon emission computed tomography/computed tomography images are commonly used to evaluate the final diagnosis of fever of unknown origin. We presented a case of fever of unknown origin undergone 67Ga scintigraphy and an intra-abdominal 67Ga avid tumor was detected which suspected to be a neoplasm. Further contrast enhanced computed tomography revealed that the lesion was a large renal carbuncle. We concluded that the contrast-enhanced CT or single photon emission computed tomography/computed tomography with contrast enhancement can be performed to further improve diagnostic performance.

A New Method for Predicting the UL of Circular CFST Columns  [PDF]
Xinmeng Yu, Baochun Chen
Open Journal of Civil Engineering (OJCE) , 2013, DOI: 10.4236/ojce.2013.33023
Abstract:

Concrete filled steel tube structures have gained booming development in recent decades, especially in China. Simplified methods have been proposed in design codes, such as the Eurocode 4 (EC4) and the China engineering and construction specification (CECS). In EC4, the confinement effect is reasonably related to slenderness and load eccentricity. The CECS method is much straight forward in that the slenderness ratio and load eccentricity are treated as independent reduction factors. To make use of the advantages of both the CECS and the EC4 methods, the CECS method is modified to consider the confinement effect associated with slenderness and load eccentricity. It is shown that the proposed method can predict well the ultimate load capacity of circular section concrete filled steel tube columns.

The Lonelier, the More Conservative? A Research about Loneliness and Risky Decision-Making  [PDF]
Yu Zhu, Chen Wang
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.810104
Abstract: Mountings of studies discussed about a variety of antecedent factors of risky decision making, however, loneliness, as a vital psychological state featured by affection, cognition as well as behavior, was seldom connected to risky decision-making. The current study aims to figure out whether loneliness would influence decision making under risks and the possible underlying mechanism. Two hundred and fifty participants attended our studies and completed gambling games via either pen-paper or E-Prime software. The results indicate that higher level of loneliness predicts less perceived self-control, which in turn leads to a tendency to avoid risks. However, this effect is only significant in gain scenarios rather than loss scenarios, suggesting there might exist an interaction between loneliness and condition factor. Our findings contribute to previous research by verifying that the preventive focused mind-set of loners can go beyond social events and influences decision making behaviors.
Exponential Dichotomies and Homoclinic Orbits from Heteroclinic Cycles  [PDF]
Tiejun Chen, Yu Xiang, Yuxiao Chen
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.22014
Abstract: In this paper, we investigate the homoclinic bifurcations from a heteroclinic cycle by using exponential dichotomies. We give a Melnikov—type condition assuring the existence of homoclinic orbits form heteroclinic cycle. We improve some important results.
Some Properties of Solution to Semidefinite Complementarity Problem  [PDF]
Yu Chen, Cuiling Chen, Caihong Han
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.61012
Abstract: In this paper, we discuss the nonemptyness and boundedness of the solution set for P*-semidefinite complementarity problem by using the concept of exceptional family of elements for complementarity problems over the cone of semidefinite matrices, and obtain a main result that if the corresponding problem has a strict feasible point, then its solution set is nonemptyness and boundedness.
Comparative study of kidney-tonifying recipes and spleen-invigorating recipe on regulating pattern of the expression of T lymphocyte apoptosis signaling-related genes in corticosterone-treated rats

Abstract: Objective: To investigate the regulating pattern of kidney-tonifying recipes and spleen-invigorating recipe on the expression of T lymphocyte apoptosis signaling-related genes in corticosterone-treated rats. Methods: We analyzed the activation-induced T lymphocyte apoptpsis rate through TUNEL-labelled flow-cytometry assay, quantified the mRNA expression level of T cell apoptosis-regulating genes by using the fluoresecence real-time PCR, analyzed the activity of caspase-8 and caspase-3 by colorimetric assay. Results: (1) T lymphocyte apoptosis rate of corticosterone-treated rats was higher than that of the normal control rats; T lymphocyte apoptosis rates of Youguiyin treated rats and Bushen Yishou Capsule treated rats were lower than that of the corticosterone-treated group; T lymphocyte apoptosis rate of Sijunzi Decoction treated rats displayed no significance compared with that of the corticosterone-treated group. (2) Pro-apoptotic genes such as Fas, FasL, TNFR1, and Bax displayed increased expression level in corticosterone-treated group compared with normal control group. Two kidney-tonifying recipes down-regruated the expression level of FasL and TNFR1, at the same time, both recipes up-regulated the expression level of Bcl-2.The spleen-invigorating recipe had up-regulating effect on the expression level of Bcl-2. And all these results had statistical significance. (3) The activities of caspase-8 and caspase-3 were increased in corticosterone-treated rats compared with normal control; both kidney-tonifying recipes had significant effect on decreasing the activities of these two apoptosis executioners. Conclusion: The excessive apoptosis of T cell in corticosterone-treated rats could be effectively modulated with two kidney-tonifying recipes. Down-regulating the expression of FasL and TNFR1 and up-regulating the expression of Bcl-2 as well as decreasing the activities of caspase-8 and caspase-3 may be the unique regulating pattern of tonifying-kidney method with respect to T cell apoptosis related genes in corticosterone-treated rats
