关于20世纪50—70年代文学史教学的思考——米尔格兰姆的启示

米尔格兰姆的试验结果之于20世纪50-70年代文学史教学的启示在于：它提醒我们在面对那些负面的文学史事件时应更多地对“组织环境”，也应对作家同样具有的“服从权威”这一人性特点作出反思。从这个角度来看．20世纪50-70年代文学史的讲授对帮助学生认知“组织环境”与文学生存之间的关系、促进对中国知识分子独立精神品格的深刻反思应该说是有相当独特的价值的。

Residual stress distribution in different depths of TiNi/Ti_2Ni-based laser clad coating prepared at different environmental temperatures

This study aimed to effectively reduce the cracking susceptibility of the laser clad coating by enhancing the environmental temperature during laser cladding,and reveal the residual stress distribution in different depths of the coating.The TiNi/Ti2Ni-based coatings were prepared on Ti6Al4V by laser cladding at different environmental temperatures of25,400,600and800°C.The changes in residual stress along the depth of the coatings were investigated in detail by the nanoindentation method.Results showed that the average residual stress of2.90GPa in the coating prepared at25°C was largest.With the increase in environmental temperature,the average residual stress was reduced to1.34GPa(400°C),0.70GPa(600°C)and0GPa(800°C).For all the coatings,the residual stress was increased with increasing the distance from the coating surface.Enhancing the environmental temperature can effectively reduce the cracking susceptibility of the coatings.

Soil Organic Carbon Storage in China

Soil organic carbon (SOC) storage under different types of vegetations in China were estimated using measured data of 2 440 soil profiles to compare SOC density distribution between different estimates, to map the soil organic carbon stocks under different types of vegetation in China, and to analyze the relationships between soil organic carbon stocks and environmental variables using stepwise regression analyses. Soil organic carbon storage in China was estimated at 69.38 Gt (10 15 g). There was a big difference in SOC densities for various vegetation types, with SOC distribution closely related to climatic patterns in general. Stepwise regression analyses of SOC against environmental variables showed that SOC generally increased with increasing precipitation and elevation, while it decreased with increasing temperature.Furthermore, the important factor controlling SOC accumulation for forests was elevation, while for temperate steppes mean annual temperature dominated. The more specific the vegetation type used in the regression analysis, the greater was the effect of environmental variables on SOC. However, compared to native vegetation, cultivation activities in the croplands reduced the influence of environmental variables on SOC.

Stress corrosion cracking behaviour of 7xxx aluminum alloys: A literature review

Stress corrosion cracking （SCC） is degradation of mechanical properties under the combined action of stress and corrosive environment of the susceptible material. Out of eight series of aluminium alloys, 2xxx, 5xxx and 7xxx aluminium alloys are susceptible to SCC. Among them, 7xxx series aluminium alloys have specific application in aerospace, military and structural industries due to superior mechanical properties. In these high strength 7xxx aluminium alloys, SCC plays a vital factor of consideration, as these failures are catastrophic during the service. The understanding of SCC behaviour possesses critical challenge for this alloy. The main aim of this review paper is to understand the effect of constituent alloying elements on the response of microstructural variation in various heat-treated conditions on SCC behavior. Further, review was made for improving the SCC resistance using thermomechanical treatments and by surface modifications of 7xxx alloys. Apart from a brief review on SCC of 7xxx alloys, this paper presents the effect of stress and pre-strain, effect of constituent alloying elements in the alloy, and the effect of environments on SCC behaviour. In addition, the SCC behaviours of weldments, 7xxx metal matrix composites and also laser surface modifications were also reviewed.

Mesenchymal stromal cells' role in tumor microenvironment:involvement of signaling pathways

Mesenchymal stromal cells(MSCs) are adult multipotent stem cells residing as pericytes in various tissues and organs where they can differentiate into specialized cells to replace dying cells and damaged tissues. These cells are commonly found at injury sites and in tumors that are known to behave like "wounds that do not heal." In this article, we discuss the mechanisms of MSCs in migrating, homing, and repairing injured tissues. We also review a number of reports showing that tumor microenvironment triggers plasticity mechanisms in MSCs to induce malignant neoplastic tissue formation, maintenance, and chemoresistance, as well as tumor growth. The antitumor properties and therapeutic potential of MSCs are also discussed.

Study on the Biology and Epidemiology of Uncinula necator---The Causal Agent of Grape Powdery Mildew Disease

This study was carried out during 2007-2009 in the vineyards of Ardebil province of lran to study the biology and the epidemiology of Uncinula necator--the causal agent of grape powdery mildew disease. The study concentrated on the survival and the initiation of primary inoculum of the fungal causal agent. Results of histopathological experiments indicated that U. necator survived as mycelium in the dormant buds of the grapes during winter season. Results of study on the effect of environmental factors on fungus biology showed that the pathogenic activity of the fungus began when the temperature was between 16-19 ℃ with a relative humidity more than 50%. It was also found that optimum temperature and relative humidity for the sporulation of U.necator was 20-25 ~C and 50%-100% respectively. According to the results, fungal conidia were trapped during formation of 5-6 true leaves and first disease symptoms were observed on the clusters on late June after fruit formation. Fungal cleistothecia were observed abundantly at the end of season on the leaves, petioles and twigs but they were not able to survive during winter. Formation of ascospores on young leaves was proved but their role as the primary inoculum was not supported by the results of this study. Results of this study and the new findings on the biology and epidemiology of U.necator may be of national and international interests for the management of powdery mildew disease which is one of the most destructive diseases around the world including Iran.

On the Relationship between China and the International Energy Agency

As China needs to play a more active role in global energy governance, it must create a diversified, multi-level system to enhance energy security and to alleviate environmental pressures. A China-IEA bilateral relationship exists under an Association Initiative, but a stronger bond is needed. Though it is not an IEA member, China's massive energy needs makes it sensible that the two sides overcome existing obstacles that include OECD membership, statistical information issues and energy autonomy. In this regard an "IEA+China" might be a feasible model.

Evaluation of Hong Kong Convention in the Maritime Industry

The HKC （Hong Kong Convention） adopted by the IMO in 2009 is aimed at ensuring that ships, when being recycled after reaching the end of their operational lives, do not pose any unnecessary risk to human health and safety of the marine environment. The text of the ship recycling Convention was developed with input from the IMO （International Maritime Organization） Member States and relevant NGOs （Non-Governmental Organizations）, and in co-operation with the ILO （International Labor Organization） and the Parties to the Basel Convention. The Convention intends to address all the issues around ship recycling, taking into account that ships sold for scrapping may contain environmentally hazardous substances. It addresses concerns raised about the working and environmental conditions at many of the world ship recycling locations. Regulations in the new Convention cover： the design, construction, operation and preparation of ships so as to facilitate safe and environmentally sound recycling, without compromising the safety and operational efficiency of ships; the operation of ship recycling facilities in a safe and environmentally sound manner; and the establishment of an appropriate enforcement mechanism for ship recycling, incorporating certification and reporting requirements. This paper will present and discuss the evaluation of the Hong Kong Convention. Also it will discuss implementing the Hong Kong convention to improve the recycling business, highlighting the effect of the convention on the maritime industry.

UTR-CTOE： A New Paradigm Explaining CAATs Adoption

Computer assisted audit techniques （CAATs） are audit technologies that allow auditors to perform their audit work efficiently and effectively. However, little is known about CAATs adoption process by audit firms. Therefore, this paper adapts the technology readiness theory （TRI）, the unified theory of acceptance and use of technology （UTAUT） and the technology-organization environment （TOE） framework and Denison organizational culture theory, and presents a new theory of unified technology readiness and cultural-technological-organizational-environmental model （UTR-CTOE）, to explain CAATs adoption at both individual level and firm level. The methodology used in the study consists of a random sampling among the auditors through the administration of questionnaire. A total of 581 auditors registered with Mauritius Institute of Professional Accountants （MIPA） respond to the survey. Our main findings of this paper confirm that the relation between beliefs, such as perceived usefulness, perceived ease of use, facilitating condition and social influence, and motivation is positively correlated, while beliefs have a negative correlation with inhibition towards CAATs adoption. Results also indicate that firm＇s decision for CAATs adoption is positively influenced by cultural, technological, organizational, and environmental factors. Furthermore, there is an indirect impact of firm＇s internal and external influences on auditors＇ adoption of CAATs.

Use of Facility Management as a Competitive Advantage in the Organizational Environment

Facility management has been widely used in corporations during the last decade and has undergone major changes. Some companies have decided to no longer outsource such services, managing more closely and assertively with a focus on cost reduction and delivery quality. At this point, there are many difficulties in the implementation of a structured maintenance, which results in generating effort, costs and delay in servicing internal customers. Currently, there are very few specialized courses in facility management in Brazil. The search for skills has become increasingly important taking into account increasingly competitive markets. The main objective of this article is to show the importance and the challenges of a good facility management, the impact on the Core business of the company and the risks of an implementation without well-defined processes.

Facilitating knowledge management strategies through IT and HRM

In an increasingly competitive environment, where new business practices are regularly introduced, organizations have to be innovative to survive. In the present competitive climate, knowledge is considered as the main distinguishing factor of business success, and it is seen as the foundation of organization＇s innovation. The emergence of knowledge-intensive society has changed the nature of business competition. Hence knowledge needs to be appropriately managed. Knowledge Management （KM） focuses on managing different knowledge processes such as acquiring, creating, storing, sharing, transferring and applying implicit and explicit knowledge with objective of product and process innovation, performance development and sustainable competitive advantage. This paper tries to demonstrate KM lead to promotion of innovation and performance when it is correctly supported by human resource management （HRM） and information technology （IT）. The questions we will try to investigate in this paper are： How knowledge in organizations can be managed？ What is the connection between HRM, IT and effective implementation knowledge management strategies and how these relationships affect on organizational goals？ For this means, this study ftrst states the importance of knowledge, KM process and introduces two strategies for managing knowledge （exploitative and explorative strategy）. Next, it demonstrates each strategy requires to desired facilitator to support them in action. Finally, with presenting of model, this study concludes that each one of strategy can cover some KM process. Hence for the effective implementation of knowledge management process, organizations have to utilize both strategies.
