The Impact of Technology Selection on Innovation Success and Organizational Performance  [PDF]
Shengbin Hao, Bo Yu
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.34049
Abstract: This paper is to analyze the impact of a company’s technology selection on its innovation success and organizational performance. Technological capability enables a company to add value to products and processes, and its impact on innovation success has been examined. Apart from technological capability, a company also needs technology management capability to manage technological resources effectively and efficiently. In this paper, we develop a theoretical model for implementation of technology selection, consisting of five elements: technology selection, technological capability, technology management capability, innovation success and organizational performance. The model is empirically tested using the data of 120 Chinese companies acquired by interviews and surveys. The results indicate that a company’s technology selection has no direct impact on innovation success; technology selection has a significant positive impact on technological capability and technology management capability, which, in turn, have a significant positive impact on innovation success; innovation success has a significant positive impact on organizational performance.
TEST OF THE MEDIATING EFFECTS OF SELF-REGULATION BETWEEN TRANSFORMATIONAL LEADERSHIP AND ORGANIZATIONAL COMMITMEN
Bo Yu
Business and Management Review , 2011,
Abstract: Based on the analyses of relevant theories, we first explained the self-regulation process of goal setting, selfefficacy, and goal self-concordance and studied the relationship between transformational leadership and selfregulation. A conceptual model was proposed to explain how transformational leadership influences organizational commitment by the self-regulation course. Using the sample of 309 data, we selected the dean of the college and the teacher in some universities in China as the leader and follower to do pairing research and tested the mediating effect of goal setting, self-efficacy, and goal self-concordance in the path by which transformational leadership exerted action. Our hypotheses were tested by the structural equation modeling analysis and the testing procedure of mediating effects and the criterion of judging mediating effects. The research changes our views on the role of goal setting, self-efficacy, and goal self-concordance in the functional mechanism of transformational leadership.
Recycling of Cobalt by Liquid Leaching from Waste 18650-Type Lithium-Ion Batteries  [PDF]
Liangmou Yu, Bo Shu, Shiwen Yao
Advances in Chemical Engineering and Science (ACES) , 2015, DOI: 10.4236/aces.2015.54043
Abstract: In this work, we recover cobalt from waste 18650-type lithiumion batteries by acid leaching. The cathode material is completely dissolved, after leaching waste batteries by using 10 mol/L industrial sulfuric acid at 70℃ for 1 h. The rate of cobalt leaching is nearly 100%. Removal of sodium carbonate, iron, aluminum and other impurities from the leaching solution was well performed by adjusting the pH to 2-3 with stirring vigorously. Finally, under the conditions of 55℃-60℃ of 240 A/m2 current density, electrodeposition current efficiency was 90.01%, the quality of the electrical output achieved cobalt 1A standard electrolytic cobalt, cobalt until greater than 90% yield. The process is easy and suitable for large-scale lithiumion batteries used in the recovery of valuable metals.

Abstract: se of lorcaserin in the management of obesity: a critical appraisal Review (7558) Total Article Views Authors: Bo Bai, Yu Wang Published Date December 2010 Volume 2011:5 Pages 1 - 7 DOI: http://dx.doi.org/10.2147/DDDT.S11945 Bo Bai, Yu Wang Department of Pharmacology and Pharmacy, Li Ka Shing Faculty of Medicine, University of Hong Kong, Hong Kong, People’s Republic of China Abstract: Obesity is a chronic disease with a high prevalence in both developed and developing countries. Effective management of this worldwide epidemic will have a significant impact on the health care system globally. Lifestyle interventions, such as restricting calorie consumption and increasing physical activity, remain a major component of weight-reduction programs. The development of pharmacotherapy for the management of obesity is still at the infancy stage. Side effects have been the key issue for anti-obesity drugs previously withdrawn from the market. The focus of this review, lorcaserin, is a selective serotonin receptor agonist that is currently undergoing Phase III evaluations. The efficacy of this drug in reducing body weight and improving metabolic parameters of obese patients has been demonstrated in two recent clinical trials. The available evidence indicates that this drug does not show unwanted effects on heart valves or pulmonary artery pressure, and the treatment improves the risk factors for type 2 diabetes and cardiovascular diseases. Despite these promising results, additional experimental and clinical studies are critical for the approval of lorcaserin as a new anti-obesity monodrug therapy by the US Food and Drug Administration.
A triclinic polymorph of (E)-2-(2-nitroethenyl)furan
Lin Li,Bo Yu
Acta Crystallographica Section E , 2010, DOI: 10.1107/s160053681002492x
Abstract: The title compound, C6H5NO3, crystallizes in the triclinic system with six independent molecules in the asymmetric unit. In a previous study, the structure of the title compound was determined in the monoclinic P21/n space group at 100 K [Valerga et al. (2009). Acta Cryst. E65, o1979]. All six independent molecules display an E configuration about the C=C double bond, with the dihedral angles between the planes of the furan rings and the nitroalkenyl groups ranging from 0.61 (7) to 5.03 (7)°. The crystal structure is stabilized by intermolecular C—H...O hydrogen-bonding interactions.

Abstract: Objective: To observe the effects of resveratrol on proliferation of human hepatocellular carcinoma cell line SMMC-7721 cells and expression of matrix metalloproteinase-9 (MMP-9) in vitro.Methods: SMMC-7721 cells were treated with different concentrations of resveratrol for 24, 48 and 72 h, respectively. The effect of resveratrol on proliferation of SMMC-7721 cells was assessed with methyl thiazolyl tetrazolium (MTT). The expression of MMP-9 mRNA was determined by reverse transcription polymerase chain reaction (RT-PCR). MMP-9 protein was identified by Western blot analysis.Results: Resveratrol could inhibit the proliferation of SMMC-7721 cells with dose- and time-dependent effects. Moreover, both MMP-9 mRNA expression and MMP-9 protein production were markedly reduced after resveratrol treatment. Conclusion: Resveratrol can inhibit the proliferation of SMMC-7721 cells and down-regulate MMP-9 expression. It is presumed that resveratrol may suppress the invasion and metastasis of hepatocellular carcinoma.
Effects of genistein on interleukin-1β and tumor necrosis factor-α secreted by fibroblast-like synoviocytes isolated from type Ⅱ collagen-induced arthritis rats

Abstract: Objective: To investigate the effects of genistein (Gen) on interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) secreted by fibroblast-like synoviocytes (FLSs) of rats with type Ⅱ collagen-induced arthritis (CIA).Methods: Type Ⅱ collagen was injected to induce arthritis in rats, and arthritis index was applied to evaluate whether the arthritis was induced successfully. The primary FLSs were separated from synovial membranes by using type Ⅱ collagenase digestion. Then the expression of vascular cell adhesion molecule-1 (VCAM-1) was estimated by flow cytometry (FCM). After addition of different concentrations of Gen into the FLSs, IL-1β and TNF-α contents in the supernatants were measured by enzyme-linked immunosorbent assay.Results: Three days after collagen injection, the rats started to develop arthrocele and the arthritis index increased gradually. The arthritis index of CIA group was significantly higher than that of the control group. The expression of VCAM-1 was up to 85.5% in the 4th generation FLSs, indicating that most part of the cultured cells were type-B synoviocytes. After administration of different concentrations of Gen (100, 200, 400 μmol/L), the contents of IL-1β and TNF-α in supernatants of FLSs were decreased dose-dependently.Conclusion: Genistein can suppress the secretion of TNF-α and IL-1β in FLSs dose-dependently, which may be one of the mechanisms for genistein in inhibiting the arthromeningitis of CIA rats.

Journal of Chongqing Normal University , 2009,
Abstract: Through discussing the singuiar perturbed problem of parabolic type and first-order hyperbolic type in partial differential equations, this paper puts forward a boundary layer format without losing its characteristics. Furthermore, initial and boundary values problems of parabolic-type singular perturbation on Ω1 and Ω2 are researched. In the use of asymptotic method, difference method and two-point boundary value problem methods in ordinary differential equation, we have gained a numerical solution to boundary layer in partial differential equation. Moreover, on the premise of step size middling and h, t and εeach approaching to zero, when free functions and initial, boundary values condition functions are smooth functions given, we obtain a uniformly numerical approach solution to the singular perturbed problem of one partial different equation with a small parameter ε(O<ε《1). Finally, we apply the conclusions to practice.
