Work safety and sustainable development in enterprise

The nature of work safety and the way insisting on sustainable development in enterprise were analyzed. It indicates that problem of work safety in enterprise is closely related to the public’s consciousness, to the development of science and tech- nology, and to the weakening of safety management during the economic transition pe- riod. However, it is the people’s questions concerned in the final analysis for the forming and development of the problem of work safety. Therefore, in order to solve the problem of work safety radically, the most basic way of insisting on the sustainable development in safety administration is to do a good job of every aspect about people. We should im- prove all people quality in science and culture and strengthen their safety and legal consciousness to form correct safety value concept. We should fortify safety legislation and bring close attention to approach and apply new safety technology.

Corporate Governance, Sustainable Development and Value Creation Some Evidences From Italian Listed Companies

Modern corporate situations, characterized by the globalisation of the markets and of the information, highlight the need to link the potential of a not transient growth to the adequate reconciliation of all the expectations converging around the entrepreneurial formula and not only of those attributable to shareholders. In such a defined context, corporate governance tends to evolve from a situation of primary care for the expectations of shareholders （shareholder＇s view） and for the correlated financial responsibility, to a wide consideration of all the stakeholders （stakeholder＇s view） and related responsibilities （financial, environmental, social, administrative）. The correct carrying out of governance processes requires, therefore, a clear focus on sustainable development and on the related assumption of a concept of global responsibility. The decisions made by the governing bodies must be driven by the purpose to create value in the long term according to conditions of fairness and sustainable development. To sum up, this research aims to deepen the existing connections between corporate governance, sustainable development and value creation on the basis of the empirical analysis of a limited number of listed Italian companies afferent to the public utilities sector. The paper, based on a deductive approach, is composed of two distinct but strictly connected parts： the first theoretical and the second empirical. The empirical research consists of a content analysis of the most recent documents （sustainability reports and annual reports） worked out by the selected companies. The results obtained about the degree respect of sustainable development conditions by each company are linked to the related value dimension （social, economic, competitive and environmental performance） aimed at verifying if the assumption of a corporate governance approach inspired by sustainability is susceptible of favouring the company development in a medium long term. From the delivered research it emerges how public utilities that promote behaviours in line with the sustainability conditions are marked out by stable growth paths. Conversely, the companies that assume a vision mainly addressed to the economic dimension, neglecting the other areas are generally compromised in the performance realized.

Cold In-Place Recycling as a Sustainable Pavement Practice

Pavement rehabilitation and reconstruction methods with CIR （cold in-place recycling） are alternatives that can effectively reduce the high stresses and waste produced by conventional pavement strategies. An attempt was made to predict the performance, particularly low-temperature cracking resistance characteristics of CIR mixtures. These were prepared with the mix design procedure developed at the URI （University of Rhode Island） for the FHWA （Federal Highway Administration） to reduce wide variations in the application of CIR mixtures production. This standard was applied to RAP （reclaimed asphalt pavement） to produce CIR mixtures with CSS-Ih asphalt emulsion as the additive. By adjusting the number of gyrations of the SGC （Superpave gyratory compactor） for compaction, the field density of 130 pcf was represented accurately. To secure a base line, HMA （hot mix asphalt） samples were produced according to the Superpave volumetric mix design procedure. The specimens were tested using the IDT （indirect tensile） tester according to the procedure of AASHTO T 322 procedure at temperatures of-20, -10 and 0 ℃ （-4, 14, and 32°F, respectively）. The obtained results for the creep compliance and tensile strength were used as input data for the MEPDG （mechanistic empirical pavement design guide）. The analysis results indicated that no thermal or low-temperature cracking is expected over the entire analysis period of 20 years for both HMA and CIR mixtures. Thus, it appears that CIR is a sustainable rehabilitation technique which is also suitable for colder climates, and it is recommended to conduct further investigation of load-related distresses such as rutting and fatigue cracking.

Urbanization with Chinese Characteristics

As a result of substitution of capital for labor in agriculture and rigid demand of urban sectors for migrant workers,the rural-to-urban migration becomes irreversible process,and Todaro dogma,which aims to limit the migration under the assmnption of ＂come-and-go＂ migration pattern,becomes and old-fashioned theory for policy-making.By empirically confirming the advent of the Lewis turning poing-namely,a new stage of labor migration and more generally of economic development,the paper reveals the policy implication of the Lewis turning point and proposes the policy reforms needed for a complete urbanization,including hukou system reform and equalization of public services.

New Changes in the International Situation and China＇ s Strategic Choices

The international situation is evolving more impressively than it has at any time since the end of the Cold War. Globalization has been in decline. Nations are scrambling to gain greater influence. The intemational strategic pattern is being adjusted. Many countries have problems with public management, and are faced with a new array of social trends and increasingly popular movements. The world is entering a new era full of chaos and anxiety. Mankind once again faces significant trade-offs and choices in peace and conflict, development and recession, openness and isolation, liberalism and conservatism. China strives to advocate win-win cooperation and lead the trend of reform and opening to maintain a favorable external environment despite world chaos, and enhance status and institutional fights in the international system. China＇s 30 years of development was successful in the process of integrating into the existing international system; China is a participant as well as a builder of the international system, rather than a challenger or a subversive. In the future, with a constructive attitude, China will promote the international system in a more reasonable direction together with international partners, in order to better safeguard world peace and security, and promote sustainable development throughout the world.

The Prospect of Ethical Consulting

Ethical consulting is a critical professional activity that is very critical to the very survival of the corporate world and is thus likely to boom within the shortest possible time in the future. This predictive statement is based on the consequential effect of the bankruptcy of Ertron and WorldCom and its aftermath legislature, Sarbanes-Oxley Act （Lander, 2004）. The main issues boarder on how ethics influence organizations＇ operations and to what extend these influences can be coded and managed to enhance objectivity and minimize fraud. The methodology applied in this paper was an exploratory approach under the qualitative design. It encapsulates a thorough review of literature on the subject matter and draws inferences to address the research objectives. It was found that ethical consulting was possible and consultants venturing into the area need to be strategically diversified to enable them to design and develop customized ethical codes for the heterogeneous clientele with appropriate supporting monitoring and compliance procedures.

Urban Big Data and the Development of City Intelligence

This study provides a definition for urban big data while exploring its features and applications of Chi- na＇s city intelligence. The differences between city intelligence in China and the ＂smart city＂ concept in other countries are compared to highlight and contrast the unique definition and model for China＇s city intelligence in this paper. Furthermore, this paper examines the role of urban big data in city intel- ligence by showing that it not only serves as the cornerstone of this trend as it also plays a core role in the diffusion of city intelligence technology and serves as an inexhaustible resource for the sustained development of city intelligence. This study also points out the challenges of shaping and developing of China＇s urban big data. Considering the supporting and core role that urban big data plays in city intel- ligence, the study then expounds on the key points of urban big data, including infrastructure support, urban governance, public services, and economic and industrial development. Finally, this study points out that the utility of city intelligence as an ideal policy tool for advancing the goals of China＇s urban de- velopment. In conclusion, it is imperative that China make full use of its unique advantages-including using the nation＇s current state of development and resources, geographical advantages, and good hu- man relations-in subjective and objective conditions to promote the development of city intelligence through the proper application of urban big data.

Possibilities and Contradictions of Nanotechnology Applications in Preventive Activities Insurer

One effective and proven tool for managing risk is insurance. At the same time, insurers, reinsurers, insurance, and reinsurance brokers in search of the relevant value of their services in the eyes of insured and long-term benefits are increasingly paying attention to the possibilities of nanotechnology. On one hand, insurers see unlimited possibilities of nanotechnology in preventive and repressive activity in relation to losses. The obstacle in this case, for high-tech companies, is stiff competition from companies which are not innovation leaders, but with the necessary influence and power at the international and national market. On the other hand, understanding the reasons for the application of nanotechnology in the conflict prevention activities of the insurer allows him to develop and implement a more flexible strategy for sustainable development of the business.

Sustainability Impact on Construction Management in Developing Countries： Iraq as a Case Study

Sustainable development contributes to the economic and social advancement of construction projects. Ignoring sustainability during the cost estimating process associated with evaluation phase develops many problems of conventional decision methodology used in construction industry in the most of developing countries. This research focuses on sustainability which is the key factor in all decision making in design and construction processes. Therefore, Iraqi construction industry should respond to sustainability as a leading indicator of its infrastructure rebuilding. The construction management and sustainability could help to manage the rebuilding of the destroyed public infrastructure during the disaster wars periods passed thru thirty years ago and also to modernize of private buildings and plants. Field study has been carried out by adopting personal interviews and questionnaires conducted with experts, experienced consultants and designers working in many design organizations. The data collected has been analyzed and the results obtained show a clear weakness in the field of sustainability understanding, practicing and implementation. Moreover, the design work in Iraq is suffering from a lack of scientific techniques and a lack in experience in the domain of sustainability field. This will take an integrated approach to study the impact of sustainability on construction management which encompasses both public and private sector perspectives for building and engineering construction, and the roles played by all the participants in the construction team （owners, contractors, design professionals, and other supporting professionals）.
