Carbon emissions permits has its own particularity,and with the development of carbon finance,carbon emissions permits possess the commodity attributes and financial attributes.So its price isn’t determined only by the relationship of commodity supply and demand,but also affected by a variety of factors.But because the transaction data is not available,so the pricing of the carbon emissions permits can not really consider from the angle of the influencing factors of price.Therefore, this paper is on the basis of previous studies using mathematical tools and introducing the option pricing mechanism to study th pricing of China's carbon emissions permits basing on carbon emissions,which is designed for providing reference on the pricing of China's carbon emissions,being of both theoretical and practical significance.

<abstract> <p>The contribution aims to highlight the relationship between the business economy applied to viticulture and the ecosystem. The concepts of ecosystem services and viticultural biodiversity are seen in order to provide a new perspective for the development of a more sustainable business management. The work contributes to enriching the economic literature by introducing the relationship between ecosystem and business. The new perspective helps to place the company within the wider ecological-social system, favoring a more consistent interpretation of the relationship of exchange (impact and dependence) of resources with nature. The work proposes a methodology for calculating the ecosystem service rendered by the vineyards cultivated in the Sicilian hills. The conceptual scheme and the methodology adopted highlight the value of the ecosystem service. Certainly, for the future, it is necessary to create business models where ecosystem services find a remuneration as the entrepreneur is led to adopt cultivation practices in this sense only if he finds a remuneration from the public or private sector. Ecosystem services are important to protect the landscape and the environment. The paper proposes a land management method that respects the environmental balance. This approach leads to long-term value creation at both the micro and macroeconomic levels.</p> </abstract>

In recent years, the Algerian labor market has undergone drastic changes as a result of supply and demand shocks caused by a drop in unemployment rates from 17.7% in 2003 to 11.7% in 2018 according to (ONS) data. However, this decline was more quantitative than qualitative, Under the age of 30, with a ratio of 60% among the new job seekers.In this paper, we will attempt to analyze the trends of the labor market and its ability to absorb youth unemployment through the field study carried out at the Tlemcen State level in 2017 to study the causal relationship between social and economic variables related to the development of labor resources, Linear approach based on the Statistic program.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
