Interpretation of the organization and performance of the university procurement under the SCP paradigm and analysis of its development trend

The organizational structures and the performances of the university procurement are rarely studied. Through the SCP perspective in the modem industrial economics, we can not only reveal the roles of the public organizational structures in the organizational performances, but also help to reflect the problems existing in the organizational structures from the performances, and improve the market performances by optimizing the organization structures. This paper tries to put forward the relationship between them, and makes an analysis of the future development trend.

Effect of Social Capital on Performance of Smallholder Farmer Organizations in Western Kenya

Development literature has recently promoted the use of producer organizations in linking farmers to better-paying commodity markets. However, empirical studies find mixed performance of such organizations. This study examines the producer organizations＇ internal factors that may explain the differences in the performance of producer organizations. The study specifically analyzes the role of social capital, within a producer organization, on the performance of such organization using quantitative techniques. The level of commercialization is used as proxy of organization＇s performance. The study finds that social capital positively affects the performance of producer organizations. These findings imply that development strategies that target the promotion commercialization of smallholder agriculture through producer organizations should pay attention to the internal factors within such organizations.

Improvement of Performance of Organic Light-Emitting Diodes with Both a MoO3 Hole Injection Layer and a MoO3 Doped Hole Transport Layer

We improve the performance of organic light-emitting diodes （OLEDs） with both a MoO3 hole injection layer （HIL） and a MoO3 doped hole transport layer （HTL）, and present a systematical and comparative investigation on these devices. Compared with OLEDs with only MoO3 HIL or MoO3 doped HTL, OLEDs with both MoO3 HIL and MoO3 doped HTL show superior performance in driving voltage, power efficiency, and stability. Based on the typical NPB/Alq3 heterojunction structure, OLEDs with both MoO3 HIL and MoO3 doped HTL show a driving voltage of 5.4 V and a power efficiency of 1.41 lm/W for 1000 cd/m2, and a lifetime of around 0. 88 h with an initial luminance of 5268 cd/m2 under a constant current of 190 mA/cm2 operation in air without encapsulation. While OLEDs with only MoO3 HIL or MoO3 doped HTL show higher driving voltages of 6.4 V or 5.8 V and lower power efficiencies of 1.201m/W or 1.341m/W for 1000cd/m2, and a shorter lifetime of 0.33 or 0.60h with an initial luminance of around 5122 or 5300cd/m2 under a constant current of 200 or 216mA/cm2 operation. Our results demonstrate clearly that using both MoO3 HIL and MoO3 doped HTL is a simple and effective approach to simultaneoasly improve both the hole injection and transport efficiency, resulting from the lowered energy barrier at the anode interface and the increased hole carrier density in MoO3 doped HTL.

Employee Satisfaction： A Case Study at Bank Muamalat Malaysia Berhad

Employee satisfactions emerge as the central subject in this study because employee satisfaction is one of the most important factors in determining the success of an organization. Leading from such probe, this study formulates a model to test factors that drive towards employee satisfaction. The study considers the most positive and unique factors that most organization has, thus suggests that core factors for employee satisfaction notably are leadership style, working environment, employee rewards and welfare, and organization culture. The analysis involved two phases of qualitative and quantitative techniques. First, the study is based on the management of Bank Muamalat Malaysia Berhad （BMMB） to explore how far the relevant factors opined the literature review synchronized with the issue being examined. In the second phase, the study developed a questionnaire, based on the findings to reach out 1,216 employees of BMMB in 1999. This study found few differences in the factors that affected employee satisfaction. Various independent variables hypothesized were significant. In view of more than one independent variable, the multiple regression analysis is adopted in this study. It is assumed that these independent variables： leadership style, working environment, employee rewards and welfare, and organization culture, explained the employee satisfaction variation. The results show that there is significant relationship between employee satisfaction and these independent variables. The statistical package for the social sciences was used to analyze the data. It is anyhow the result shows that the independent variable： organizational culture-the most important variable that determines employee satisfaction.

Dynamic test on waste heat recovery system with organic Rankine cycle

Dynamic performance is important to the controlling and monitoring of the organic Rankine cycle(ORC) system so to avoid the occurrence of unwanted conditions. A small scale waste heat recovery system with organic Rankine cycle was constructed and the dynamic behavior was presented. In the dynamic test, the pump was stopped and then started. In addition, there was a step change of the flue gas volume flow rate and the converter frequency of multistage pump, respectively. The results indicate that the working fluid flow rate has the shortest response time, followed by the expander inlet pressure and the expander inlet temperature.The operation frequency of pump is a key parameter for the ORC system. Due to a step change of pump frequency(39.49-35.24 Hz),the expander efficiency and thermal efficiency drop by 16% and 21% within 2 min, respectively. Besides, the saturated mixture can lead to an increase of the expander rotation speed.

Synthesis and Photovoltaic Properties of Novel Porphyrin Derivatives

The porphyrin derivatives, 5,10,15,20-tetra（4-（N-pentane-carboxamide） phenyl） porphyrin（4 NC5-TPP）, 5,10,15,20-tetra（4-（N-dodecane-carboxamide） phenyl） porphyrin（4 NC12-TPP） and their zinc-complexes（4 NC5-TPPZn and 4 NC12-TPPZn）, have been synthesized. Their thermal properties and morphologies were investigated via thermal gravity analysis（TGA）, differential scanning calorimetry（DSC） and polarized optical microscopy（POM）. It was found that the 4 NC5-TPP was amorphous and the 4 NC5-TPPZn was crystalline at room temperature, while the 4 NC12-TPP formed the columnar liquid crystal and the 4 NC12-TPPZn showed the spherulite texture. The electron state density distributions and the optimum configuration of the porphyrin derivatives were calculated by chemical simulation. The electrochemical oxidation and reduction abilities of the porphyrin derivatives were studied by cyclic voltammetry（CV）. It was indicated that the porphyrin derivatives had the potential to develop organic photovoltaic（OPV） devices. Using the porphyrin derivatives as donor materials and the 3,4,9,10-perylenetetracarboxylic dianhydride（PTCDA） as the acceptor material, the OPV devices were fabricated. The device structure is ITO/porphyrin derivatives：PTCDA/Al. The relationship between the morphology and performance of OPV was studied. It was found that the crystalline morphology of the film was beneficial to improve the efficiency of the devices.

Organic sensitizers with different thiophene units as conjugated bridges:molecular engineering and photovoltaics

Three structural modifications with incorporation of alkyl,alkoxy and vinyl bond into the skeleton of thiophene bridge in D-π-A featured organic sensitizers are specifically developed for insight into their influences on photophysical,electrochemical as well as photovoltaic properties in nanocrystalline TiO_2-based dye sensitized solar cells(DSSCs).The insertion of vinyl bond into the conjugation bridge leads to the molecular planar configuration,and the conjugation bridge of 3,4-ethylenedioxythiophene(EDOT)is prone to positively shift its highest occupied molecular orbital(HOMO).The electrochemical impedance spectroscopy(EIS)results indicate that the grafted long alkyl chain onto thiophene is favorable to suppress dye aggregation when adsorbed onto TiO_2film and modification on interface of TiO_2/dye/electrolyte,resulting in a relatively high open-circuit voltage(V_(oc)).Under optimized conditions,dye LS-4 bearing hexylthiophene as the conjugation bridge shows a relatively high overall conversion efficiency of5.45%,with a photocurrent of 11.61 mA cm^(-2),V_(oc)of 744 mV.
