Value Estimation of Greenhouse Gases Exchange in Wetland Ecosystem of Sanjiang Plain,China

The objective of this study is to quantify the values of greenhouse gases(GHGs) exchange in carbon equivalents of marshes and paddy fields in the Sanjiang Plain,Heilongjiang Province,China. We obtained the GHGs exchange values based on comparable price by calculating the carbon sequestration values and the GHGs emission values of marshes and paddy fields respectively in four periods of 1982,1995,2000 and 2005. It is noted that the GHGs emission values are always negative. In this study,the marshes areas decreased from 1438977.0 to 775,132.2ha and the paddy fields areas increased from 417195.8 to 934205.0ha. The values of GHGs exchange of marshes varied from 135877.156×106 to 136882.534×106 yuan(RMB) and those of paddy fields varied from 1006.256×106 to 2767.645×106 yuan. The GHGs exchange values of marshes decreased from 1982 to 2005 on the whole,reversely,those of paddy fields increased,but those in 2005 were lower than those in 2000. In different periods,the GHGs exchange values were always higher in marshes than in paddy fields. The contribution rate of GHGs exchange values per unit area of marshes was also very high in different periods,and the maximum was up to 98.35% in 2005. As far as the whole wetland ecosystem(including marshes and paddy fields) ,assuming a linear change in GHGs exchange values,it represented a cumulative increase of 20926.757×106 yuan from 1982 to 2005. By adding GHGs exchange values increased during those four periods,we obtained a cumulative net increase values of GHGs exchange of wetland ecosystem of 18200.860×106 yuan. The results will be useful for understanding the indirect services provided by marshes and paddy fields.

Financial Statement Valuations in Italian Accounting Thought Between the 19th and the 20th Century： From ＂Exchange Value＂ to ＂Historical Cost＂

The main subject of this paper is the theory of financial statement valuations observed in its historical development. More notably, regarding the subject, the research is concerned with some theoretical concepts developed by the Italian doctrine in a very specific age, namely, between the 19th and the 20th century, which in fact, devoid of any accounting regulation. This paper analyzes in particular the shift from the exchange value rule to the historical cost method and tries to explain the reasons of such a development. In the second half of the 19th century, some of the best Italian scholars, who were faced with the need to properly develop the problem of accounting valuations, thought that it was appropriate to rely on concepts that belonged to similar sciences, such as economics and real estate appraisal, by blindly borrowing the theory of value from the former and the theory of valuations from the latter. During that age, everything hinged around the concept of exchange value. At the dawn of the 20th century, the Italian accounting doctrine began to wonder about a subject that was crucial to the financial statement theory： the informative purposes underlying the financial statements. At the same time, the first principle took shape, which might be called as the ＂finalistic principle of value＂. It is still the basis of the theory of financial accounting measurements, for which different evaluative criteria must be applied to different informative purposes. Thus, an alternative criterion to that of the exchange value makes its appearance on the scene of the accounting valuations, notably the historical cost. The introduction of the historical cost criteria and above all the relinquishment of the combination of the ＂economic cost＂ in favor of that of the ＂manufacturing cost＂ allow the Italian accounting to get rid of the theories of economics and real estate appraisal, thus, becoming independent regarding the financial statement valuations.

Political Economy Factors Shaping News Culture of Hyperlocal News Website www.ippodhu.com

In contemporary media ecosystem, media content is not only produced by employees rather it is also produced by its users in the form of curating stories, writing feedback, engaging in online discussions and at the same time disseminating the content through their personal online profiles. Keeping these views in mind, this paper critically examines the political economy of Ippodhu (Tamil Nadu based news website), a hyperlocal news application, in terms of digital labour, audience as participatory commodities and audience as producers, which Alvin Toffler terms as prosumer. Further, this paper explores how social media, analytics, or other analytical tools create value or anti-value for Ippodhu. The qualitative data obtained through in-depth interview reveals that readers/audiences of Ippodhu are commodified in two ways, first they consume the content of the website by spending their time, which will be sold to the advertisers and secondly by creating free content either in the writing stories, uploading photographs or even in the form of comment which will be consumed by other readers/audiences which result in the chain of production of values.

Natural capital accounting perspectives:a pragmatic way forward

Introduction:Recent debates surrounding the application of natural capital accounting(NCA)have produced several approaches to further develop this system,as well as highlighted a number of conceptual and methodological issues that need to be resolved before mainstreaming NCA into policy and decision making.We argue that prolonged debate over the value concepts(i.e.,exchange versus other values)underpinning different modifications to NCA has slowed progress in experimentation and uptake by policymakers.Outcomes:Consequently we propose three broad approaches which can be progressed in parallel to reinvigorate experimentation with the NCA principles and practice,while at the same time generating policy relevant tools and evidence bases for decision support.The three approaches are;extended SNA accounting anchored to the use of exchange values;a complementary accounts network(CAN)that utilizes plural values as supplementary accounts to the SNA system;and wealth accounting that focuses on measures of welfare and wellbeing.The three approaches are complementary and data developed in any one can inform the other two.Conclusions:We contend that CAN offers the most flexibility and opportunities to progress short term support for decision making on environmental issues which are now becoming urgent.
