This science is summarized in the statements of the major scientific societies. These statements, have motivated, governments, the media, and much of the public to commit to abandoning fossil, i.e. going to “net zero” at some time in the not-so-distant future, perhaps by 2050, 26 years from now. The claims of these scientific societies clearly have a profound impact on the government, the media and the public, and therefore the scientific basis for these claims needs to be frequently and rigorously reexamined by the societies, and scrutinized by the public. This paper illustrates some serious concerns regarding the claims of these societies. It is not difficult to question these claims by comparing them with actual data from well-established organizations such as NOAA and NASA. Furthermore, the claims seem to go against such well-established scientific laws as the Stefan Boltzman radiation law, and le Chatelier’s principle. If the statements of the societies overstate the danger, or are even incorrect, they may be motivating the United States, the western world, or even the whole world to make an enormously expensive and unnecessary transition to an energy infrastructure that is more expensive, less reliable, and more environmentally damaging than the one we have today. This article suggests that these scientific societies reexamine their climate statements with the goal of making them more moderate and more scientifically correct.展开更多

It is pointed out that such three statements correspond to three thermodynamic parameters, which are, respectively, the entropy,temperature, and heat capacity, and can be obtained by extrapolating the experimental results of different parameters at ultralow temperatures to absolute zero. It is expounded that because there is no need for additional assumptions in the derivation of the Nernst equation, the Nernst theorem should be renamed as the Nernst statement. Moreover, it is proved that both the Nernst statement and the heat capacity statement are mutually deducible and equivalent, while the unattainability of absolute zero temperature is only a corollary of the Nernst statement or the heat capacity statement so that it is unsuitably referred to as one statement of the third law of thermodynamics. The conclusion is that the Nernst statement and the heat capacity statement are two equivalent statements of the third law of thermodynamics.展开更多

This paper aims to verify the compliance of the comprehensive income （CI） statement format with International Accounting Standard （IAS） 1-presentation of financial statements, which was revised in 2007. The changes introduced by the 2011 revision are also taken into account. For this purpose, this study analyzes the final annual financial statements approved in 2011 by the Italian companies whose shares belonged to the Italia Star segment of Financial Times and Stock Exchange （FTSE）. Given that IAS 1 provides little specific guidance about the presentation of line items and permits many alternative types of format, this paper focuses on information organization in the statement of CI in order to analyze the degree of heterogeneity of financial information. For achieving this goal, this study considers the following issues： （1） presentation of all items of income and expense in an overall statement or in two separate statements; （2） a detailed level of the content in terms of number of items between revenue and net income （NI）; （3） classification of expenses either by nature or by function; （4） number and type of intermediate margins; and （5） presentation of items of other comprehensive income （OCI） either before tax or net of tax. The results show some clear evidences. On the one hand, there is a high diversity in accounting practices, which makes it difficult for users to compare financial information across entities, highlighting the need to complete the joint project of the standards setters （IASB and Financial Accounting Standards Board （FASB）） on financial statement presentation. On the other hand, some alternative types of presentation （e.g., the tendency to split the CI statement into two statements rather than using an integrated solution, the prevalence to disaggregate the expenses by nature, etc.） are used by most of the entities of the sample possibly because of the influence of Italian accounting culture.展开更多

However,controversies concerns exist regarding a variety of factors including the safety,feasibility, efficacy, and cost-effectiveness of robotic surgery. To promote the development of robotic hepatectomy, this study aimed to evaluate the current status of robotic hepatectomy and provide sixty experts' consensus and recommendations to promote its development. Based on the World Health Organization Handbook for Guideline Development, a Consensus Steering Group and a Consensus Development Group were established to determine the topics, prepare evidence-based documents, and generate recommendations. The GRADE Grid method and Delphi vote were used to formulate the recommendations. A total of 22 topics were prepared analyzed and widely discussed during the 4 meetings. Based on the published articles and expert panel opinion, 7 recommendations were generated by the GRADE method using an evidence-based method, which focused on the safety, feasibility, indication,techniques and cost-effectiveness of hepatectomy. Given that the current evidences were low to very low as evaluated by the GRADE method, further randomized-controlled trials are needed in the future to validate these recommendations.展开更多

Design/methodology/approach： The method for data-usage statements extraction starts with seed entities and iteratively learns patterns and data-usage statements from unlabeled text. In each iteration, new patterns are constructed and added to the pattern list based on their calculated score. Three seed-selection strategies are also proposed in this paper. Findings： The performance of the method is verified by means of experiments on real data collected from computer science journals. The results show that the method can achieve satisfactory performance regarding precision of extraction and extensibility of obtained patterns. Research limitations： While the triple representation of sentences is effective and efficient for extracting data-usage statements, it is unable to handle complex sentences. Additional features that can address complex sentences should thus be explored in the future. Practical implications： Data-usage statements extraction is beneficial for data-repository construction and facilitates research on data-usage tracking, dataset-based scholar search, and dataset evaluation. Originality/value： To the best of our knowledge, this paper is among the first to address the important task of automatically extracting data-usage statements from real data.展开更多
