Metals, Minerals and Rock as minerals, are important aspects in the economic and social development of a country. However, due to the lack of communication between the private sector as a miner and the government as a supervisory party, there has been a lot of illegal mining occurring and no effort to revise the environment so that it has an impact on people's welfare and environmental pollution that is increasingly high. So as to reduce the level of environmental pollution that is currently needed there is the processing of mining waste. The metal will form complex bonds of coordination with ligands and form compounds of a certain color. By knowing the nature of these plants, the selection of plants that have a tendency to bind metal ions can be complexly coordinated to reduce the waste of metal ions generated from mining processing activities or on mining sites.

The purpose of this course is to introduce a new framework linking the humanities to public policy analysis as pursued in the government and the academy. Current efforts to link the particular contributions from the humanities to problems of public policy choice are often narrow either in terms of their perspective on the humanities or in terms of their selection of the possible means of influencing policy choice. Sometimes a single text from one of the humanities disciplines is selected to apply to a particular issue. At other times, arguments about the ethical dimensions of a single policy issue often are pursued with a single — or sometimes, no — point of access to the policy process in mind.

Due to the continuous changes of political environment, consumption habits, technological progress and other factors, the external environment of enterprises is full of uncertainty. The turbulence of external environment is not conducive to the long-term operation and development of enterprises, but also brings great challenges to the selection of suppliers. This makes the competition of enterprises focus on how to choose long-term cooperation suppliers in the uncertain external environment. In addition, due to the deterioration of the global environment, governments pay more and more attention to environmental pollution, and consumers are more and more inclined to green consumption, which makes many companies pay more and more attention to environmental indicators when selecting suppliers. In the case of external environment turbulence and serious environmental pollution, the evaluation and selection of green suppliers in uncertain environment is particularly important for the long-term development of enterprises. What’s more, when the supplier’s capability gap is small, the decision-maker often hesitates among several suppliers. In this paper, the hesitant fuzzy is used to describe the hesitant psychology of decision-makers in selecting suppliers, the variance fluctuation is used to describe the characteristics of hesitant fuzzy numbers, and the probability is used to measure the uncertainty of the environment. A green supplier evaluation model under the uncertainty environment is proposed, which comprehensively evaluates the green suppliers under the uncertain environment. Furthermore, it is compared with other methods that do not consider the uncertainty and the adaptability of evaluation method and right confirmation method, so as to reflect the influence of uncertainty to green supplier evaluation and the importance of adaptability of evaluation method and right confirmation method.

As for the academics and policymakers, more attention has been given to the issue on how to reduce environmental pollution through the cooperation of environmental regulation and local officials’ promotion incentives. With the use of a city-level panel data of 266 Chinese cities from 2005 to 2016, this study preliminary explores the impacts of environmental regulations, local officials’ promotion incentives, and their interaction terms on urban environmental pollution at national and regional levels by using the spatial Durbin model. The results indicate that the impacts of environmental regulations and local officials’ promotion incentives on urban environmental pollution have achieved the desired goal with the other’s cooperation, and their interaction term’s coefficients on urban environmental pollution are significantly negative. Moreover, spatial heterogeneity is established, and the uneven development of urban environmental pollution among different regions deserves more attention. In order to effectively reduce the level of urban environmental pollution in China, the government should focus on such solutions as enhancing the implementation and supervision efficiency of environmental regulation, optimizing the performance appraisal system of local officials, improving the synergistic effects of environmental regulations and local officials’ promotion incentives, and establishing a multi-scale spatial cooperation mechanism based on both geographical and economic correlations.

AbstractBlooming seasonality is an important trait in ornamental plants and was selected by humans. Wild roses flower only in spring whereas most cultivated modern roses can flower continuously. This trait is explained by a mutation of a floral repressor gene, RoKSN, a TFL1 homologue. In this work, we studied the origin, the diversity and the selection of the RoKSN gene. We analyzed 270 accessions, including wild and old cultivated Asian and European roses as well as modern roses. By sequencing the RoKSN gene, we proposed that the allele responsible for continuous-flowering, RoKSNcopia, originated from Chinese wild roses (Indicae section), with a recent insertion of the copia element. Old cultivated Asian roses with the RoKSNcopia allele were introduced in Europe, and the RoKSNcopia allele was progressively selected during the 19th and 20th centuries, leading to continuous-flowering modern roses. Furthermore, we detected a new allele, RoKSNA181, leading to a weak reblooming. This allele encodes a functional floral repressor and is responsible for a moderate accumulation of RoKSN transcripts. A transient selection of this RoKSNA181 allele was observed during the 19th century. Our work highlights the selection of different alleles at the RoKSN locus for recurrent blooming in rose.

Government fiscal positions in all the advanced economies suffered severe deteriorations during the financial crisis. Figure 1 illustrates the cumulative deterioration of the government budget ratio as a per cent of GDP between 2007 and 2009 in a selection of OECD economies. The sharpest declines materialised in Ireland, Spain and Finland, while public finances in Austria, Germany and Italy have held up better. Budget deficits have worsened in part because of the cyclical downturn, in part because of the policy response to the crisis, including both fiscal stimulus packages and certain fiscal costs related to government support of financial institutions, and in part because of a change in the relationship between revenue and production, which may prove longer-term.

The purpose of the article is to review the activities of the civil governor M.M. Oreus in the service in the Vyborg (Finland) province in 1799–1804. The guarantee of an effective mechanism of admin-istration creation as for over than 200-year period of the Russian Empire existence, as for modern conditions, it was and still is the effectiveness of the government policy on the ground. Based on this key task, the most important condition for its implementation at different stages of the development of the country was the effective selection of personnel for the post of a governor. It was the governor responsible for everything happened in his province, and the government expected him to under-stand the tasks assigned to him and take definite steps to solve them. The urgent management problem in these conditions was the strength of administrative resources capable of retaining their effective power in cases of emerging extraordinary situations, including which, will be discussed in this article. Emergency situations in the border areas occurred regularly and required the ob-servance of certain administrative traditions that influenced the success of the governor's initiatives in state tasks implementation. It will be all the more important to consider the history of the life and activities of one of the governors of the Finland (Vyborg) province, Maxim Maksimovich Oreus, who was at the head of this territory from December 14, 1799 to April 9, 1804.
