Quanzhou Bay

Owing to the development of the social economy, the geographical environment and ocean utilization patterns of urban coastal zones have changed. This change, in turn, has influenced the socio-economic development of urban coastal zones. Based on the Geographic Information System technology, the area, coastline length, and shoreland use function of reclamation areas were obtained from the geographic charts (1954–2020) and remote sensing data (1988–2017) of Quanzhou Bay. In this study, we analyzed the geomorphologic change process and the relationship between land use patterns and economic development in Quanzhou Bay from the perspectives of hydrodynamics, sediments, and human activity. Our results indicated that over the past 70 years, the bay area has reduced by 21.5%. The length of the coastline decreased from 208.36 km in 1959 to 149.11 km in 1988, whereas the shape index of the bay (SIB) decreased from 3.09 to 2.41 during the same period. Between 1988 and 2017, the coastline increased to 162.91 km, causing the SIB to increase to 2.72. The artificial index of the bay increased from 0.28 in 1959 to 0.90 in 2017. The intensity of bay the development (IBD) first increased from 0.27 in 1959 to 0.77 in 2006. During the transition to a more modern society (2006 to present), the IBD slightly decreased to 0.73 in 2017. Affected by human activity, the transformation of the reclaimed land in Quanzhou Bay can be divided into four stages that are closely linked to the economic development in the region. In the early industrialization period, reclaimed land in the region was used for agricultural production, whereas in the mid-industrialization period, it was gradually transformed into a combination of industrial (29.8%) and agricultural (56.1%) lands. In the later period of industrialization, the reclaimed land was gradually converted into urban industrial and port lands. Finally, with further refinement and upgrading of economic and industrial structures, the socio-economic and environmental benefits from coastal reclamation projects have been increasing, whereas the proportion of economic benefits (in the total benefits) has been decreasing. The results of this study can provide decision-making references for the optimization of utilization patterns and the economic development of reclamation lands in coastal areas.

Despite numerous studies on residential rainwater tank, studies on commercial rainwater tank are scarce. Corporate authorities pay little heed on this sustainable feature. With the aim of encouraging corporate authorities, this study presents the feasibility and economic benefits of rainwater harvesting (RWH) in commercial buildings in the capital city of Bangladesh, where water authority struggles to maintain town water supply. The analysis was conducted using a daily water balance model under three climate scenarios (wet, dry and normal year) for five commercial buildings having catchment areas varying from 315 to 776 m2 and the storage tank capacity varying from 100 to 600 m3. It was found that for a water demand of 30 L per capita per day (lpcd), about 11% to 19% and 16% to 26.80% of the annual water demand can be supplemented by rainwater harvesting under the normal year and wet year climate conditions, respectively. The payback periods are found to be very short, only 2.25 to 3.75 years and benefit–cost (B/C) ratios are more than 1.0, even for building having the smallest catchment area (i.e., 315 m2) and no significant overflow would occur during monsoon, which leads to both economic and environmental benefits. Though the findings cannot be translated to other cities as those are dependent on factors like water price, interest rate, rainfall amount and pattern, however other cities having significant rainfall amounts should conduct similar studies to expedite implementations of widescale rainwater harvesting.

Molybdenum Concentrate

Technical analysis was used to analyze the roasting of molybdenum concentrate on the basis of thermal balance test of rotary furnaces used for Roasting, and the results indicate that, on the condition of commercial production, the Roasting of MoS2 can occur spontaneously because the heat of reaction is so much that proper cooling measures should be adopted in case overheating happens. According to above analysis, carbon-free roasting technology of molybdenum concentrate was proposed in this paper. The results, which come from thermal balance test and technical analysis of rotary furnaces used for carbon-free roasting of molybdenum concentrate, indicate that outer heat source used in traditional Roasting technology is not needed in carbon-free roasting technology, because enough heat is generated during Roasting to ensure spontaneous reaction. In fact, heating is not needed in operating process except at the beginning, to make molybdenum concentrate catching fire, and when reaction completing, to remove residual sulphur. The technology in this paper is obviously advantageous in aspects of energy saving, output, quality of production, heat loss, the concentration of SO2 in flue gas, etc. and will have remarkable environmental benefits, economic benefits and social benefits.

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.

Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.

The enthusiasm of immigrant sending countries around migration and development hinges on the fact that the flow of money, knowledge and universal ideas can have a positive effect on development in these countries. The Canadian Seasonal Agriculture Workers Program (CSAWP) was established in 1966, most of the Social Science literature on this program has emphasized its exploitative and problematic aspects. Without dismissing the significance of the focus and results of other research, this paper examines the social and economic development impact of this program on households and communities in Jamaica. Research done by academics and an analysis of Jamaica‟s newsprint media done for this research reveal that the CSAWP has had positive development impacts. Findings suggest that the program is delivering social and economic benefits to migrant workers and their families. It has increased income, consumption, child schooling and improved health care. In addition to improving the standard of living for migrant workers and their families, the CSAWP has additional benefits at the community and national levels.

Labour Standards

Relevance of the work. Nowadays, Russian enterprises and their employees are subjects of the labour, product, services market, and capital market. An analysis of the theory, methodology and practice of labour standards for workers in coalmining enterprises has shown that rate fixing, as one of the important institutions that regulate the quality, quantity and efficiency of labour use, restrains an employee’s subjectivity in the labour market. Lack of subjectivity is disadvantageous either to employees, or to management (to the owners of the enterprise, or the state), since it does not allow increasing labour efficiency, which is a source of workers’ dissatisfaction with the quality of working life and incomes, labour conflicts, insufficient to ensure the competitiveness of enterprises with increased productivity and labour safety, insufficient growth tax revenues to the state budget. These circumstances indicate the need to develop the theory and methodology of labour standards for workers of coal-mining enterprises aimed at increasing the market subjectivity of each employee of the enterprise by means of socio-economic standardization of his labour activity allowing the employee to satisfy his socioeconomic needs, and the enterprise to carry out socio-economic development as one of the conditions for effective functioning in a market environment. Purpose of the work – theoretical and methodological substantiation of the socio-economic standardization of labour activity of coal-mining workers as a real socio-economic phenomenon and a means to increase their market subjectivity, and for an enterprise to successfully realize the goals of socio-economic development in the conditions of high dynamics of the functioning environment. Methodology and methods of research. The methodology of socio-economic regulation of labour activity of workers is based on the theoretical and methodological provisions of the scientific organization of labour, the results of modern research on the development of labour standards in the context of the formation of a socially oriented market economy and an institutional approach that allows us studying the problems of functioning and changing the role of labour standards as one of the social and economic institutions that form the market subjectivity of the employee and the level of social -economic development of the enterprise. Results of the research. The key concepts of the methodology of socio-economic standardization are identified, the main provisions of the concept of socio-economic standardization of labour activity of coal-mining workers are developed. Conclusions. The increase in the market subjectivity of workers is ensured by the formation and adoption by the enterprise management of the socio-economic standardization of the labour activity of workers at all levels of management, which is based on the determination, establishment and maintenance of a measure of conformity of the social and economic benefits received by the employee, the results of his labour activity and the conditions for obtaining these results.

The denominations of origin and geographical indications, as distinctive signs, occupy a prominent place as an element of the impulse to the economic development of a given territory, since through them the development and marketing of high-quality products and differentiation, which in turn, allows reaching significant levels of commercial and tourist positioning for the place or region of its origin, as well as the generation of new sources of direct and indirect employment, increasing foreign exchange income from exports, the increase of State tax collection, among other socio-economic benefits. Thus, designations of origin and geographical indications are considered elements of economic development within the productive policy of a State. Therefore, the purpose of this work is to analyze the denominations of origin and geographical indications as a specialized category within the field of Trademark Law and Intellectual Property Law. It is relevant for a better understanding of how these concepts developed in Ecuadorian legislation. While for determining the options presented by the local legal framework promoting its development and use. Moreover, as those elements that the State should consider for taking advantage to promote national growth. Then the exegetical-critical method has been used, through is introduced a doctrinal and normative approach.
