Power exchange needs to design a mechanism, which can achieve the internalization of environmental costs of power generation enterprises, thus maximizing the social environmental benefits. Two-stage optimization models of energy-saving and emission-reducing for coal-fired power plant are established. In the first stage model, maximums of the social environmental benefits and energy-saving effect are taken as the objective functions with consideration of the unit output constraints, load constraints and emissions constraints, etc. In the second stage model, maximums of power generation enterprises profits are taken as the objective functions with the constraints of KKT conditions of the first stage model. The proposed marginal incentive pricing mechanism not only controlls CO2 emissions from the total amount, but also improves emissions treatment initiative of coal-fired power generation enterprises. A numerical example shows that the proposed model and algorithm can achieve the effect of saving energy, reducing emission and encouraging competition during the process of generation.

With the social development of China, new energy power generation industry keeps developing with the strong support of the government. Compared with traditional coal power, new energy power generation has more advantages in environment, energy saving and so on. China's increasingly serious pressure on energy and increasing attention to energy saving and environmental pollution reduction make the economic study of new energy power generation necessary. Under the background of global financial crisis and climate change, new energy industry development has aroused general concern, which promotes the development of new energy industry and makes it a new growth point of global economy. China's new energy industry has stepped in fast developing stage, meanwhile, new energy technology keeps developing, industry scale is rapidly increasing, new energy equipment manufacturing level and industrial technology research and development level are promoting.

First Time

At present, the problem of establishing disability is a point at issue in Russia. Despite the fact that medical criteria for disability are being developed very actively, high-quality methods for assessing social hallmarks are still lacking. Since disability is a phenomenon inherent in any society, each state forms a social and economic policy for people with disabilities in accordance with its level of development, priorities and opportunities. We have proposed a three-stage model, which includes a system for the consistent solution of the main tasks aimed at studying the causes and consequences of the problems encountered today in the social protection of citizens with health problems. The article shows why the existing approaches to the determination of disability and rehabilitation programs do not correspond to the current state of Russian society and why a decrease in the rate of persons recognized as disabled for the first time does not indicate an improvement in the health of the population. The authors proposed a number of measures with a view to correcting the situation according to the results of the study.

Two prominently discussed sustainable food alternatives—lab-meat and edible insects—elicit disgust among consumers, thereby preventing acceptance. While providing prospective consumers with more information on, for instance, the environmental benefits of lab-meat has shown some success in increasing consumer acceptance, we argue that the disgust response—the main barrier to the societal acceptance of these foods—is not addressed. This is, we argue, because disgust is not the result of misperceptions (e.g., edible insects carry diseases) and thus unlikely to be overcome by information alone. Building on the latest insights into the social origins of disgust, this manuscript reviews an alternative strategy to foster the broader acceptance of sustainable food alternatives that currently elicit disgust. Specifically, we explain why and how public exposure could be a promising avenue for marketers to reduce consumers’ disgust response and thus increase the acceptance of sustainable food alternatives.

This article is the second in a two-part series that analyzes current research on harassment in archaeology. Both qualitative and quantitative studies, along with activist narratives and survivor testimonials, have established that harassment is occurring in archaeology at epidemic rates. These studies have also identified key patterns in harassment in archaeology that point to potential interventions that may prevent harassment, support survivors, and hold perpetrators accountable. This article reviews five key obstacles to change in the disciplinary culture of archaeology: normalization, exclusionary practices, fraternization, gatekeeping, and obstacles to reporting. Two public health paradigms—the social-environmental model and trauma-informed approaches—are used to identify interventions that can be taken at all levels of archaeological practice: individual, relational, organizational, community, and societal.

This paper compares the potential for building energy saving of various passive and active strategies and on-site power generation through a grid-connected solar photovoltaic system (SPVS). The case study is a student welfare unit from a university campus located in the tropical climate (Aw) of Guayaquil, Ecuador. The proposed approach aims to identify the most effective energy saving strategy for building retrofit in this climate. For this purpose, we modeled the base line of the building and proposed energy saving scenarios that were evaluated independently. All building simulations were done in OpenStudio-EnergyPlus, while the on-site power generation was carried out using the Homer PRO software. Results indicated that the incorporation of daylighting controls accounted for the highest energy savings of around 20% and 14% in total building energy consumption, and cooling loads, respectively. Also, this strategy provided a reduction of about 35% and 43% in total building energy consumption, and cooling loads, respectively, when combined with triple low-e coating glazing and active measures. On the other hand, the total annual electric energy delivered by the SPVS (output power converter) was 66,590 kWh, from where 48,497 kWh was supplied to the building while the remaining electricity was injected into the grid.

This study examined temporal trends in body mass index (BMI) among United States adults with intellectual disability (ID) participating in Special Olympics from 2005 to 2010. In addition, the prevalence of obesity was compared with published National Health and Nutrition Examination Survey (NHANES) statistics. After data cleaning, 6,004 height and weight records (male = 57%) were available from the Special Olympics International Healthy Athletes Health Promotion database for the calculation of BMI. Rates of overweight and obesity were very high but generally stable over time. Compared with NHANES statistics, the prevalence of obesity was significantly higher for Special Olympics female participants in each data collection cycle. Integrated efforts to understand the social, environmental, behavioral, and biological determinants of obesity and among Special Olympics participants are needed.

History Of

Britain possesses a forest area which is one of the smallest in Europe in relation to its population and land area. In the past, forests have been felled to make way for farming and to supply timber for ships, houses, fuel and metal smelting. Timber was a key to sea power, and repeatedly the availability of home timber supplies has proved crucial in time of war. The nation’s dwindling reserves of timber have been a source of anxiety since Tudor times and periodic surges of planting for timber production by private landowners took place until about 1850. Thereafter, interest faded with the advent of the iron ship, the Industrial Revolution and the availability of cheap timber imports. Govern­ ment activity was minimal until a national forest authority was formed in 1919 to create a strategic timber reserve. Since 1958 there have been frequent policy reviews to assess the changing needs of the nation for timber and the new values associated with the social and environmental benefits of forests.

Sport tourism is one of the fastest growing market segments in the tourism industry and is receiving increased attention for its social, environmental, and economic impacts upon destinations. Prior research in tourism impacts has tended to focus exclusively on tourism as a whole and does not differentiate among the different types of tourism that may be present in a destination. The purpose of this study was to examine how residents of Indianapolis, Indiana perceived the impacts sport tourism has upon their city. A total of 347 surveys were returned in a mailed questionnaire. Exploratory factor analysis revealed a four factor structure of social benefits, environmental benefits, economic benefits, and general negative impacts. Social and economic benefits were strong predictors for support for further sport tourism development revealing a strong identification with the advantages of sport tourism in their city such as an increased cultural identity and social interaction opportunities.
