Diagenesis is one of the most important factors impacting the performance of many reservoirs and is perhaps the most important factor impacting the performance of tight sandstone reservoirs, such as those of the Sulige gas field in the Ordos Basin of China. However, the relationship between diagenesis and related parameters determining reservoir physical properties remains unclear. Therefore, we have analyzed experimental data from high-pressure mercury intrusion porosimetry, scanning electron microscopy, and thin sections in addition to using a porosity recovery calculation (...) model to investigate microscopic characteristics, diagenesis, and pore-evolution processes of the low-permeability tight gas reservoir of the He-8 unit of the Sulige gas field in the Ordos Basin. In addition, we have identified the impacts of diagenesis on reservoir characteristics and established the relationship between diagenesis and reservoir quality evolution. We also used the Beard primary porosity model to recover the primary porosity, and to built the reducing and enhancing calculation models for intergranular pore, dissolution pore, and intercrystalline pore during diagenesis. Based on the quantitative relationship between diagenesis processes and porosity evolution, we found that the results of simulation calculation and experimental works were in close agreement with minimal error.

The study of anarchism as a philosophical, political, and social movement has burgeoned both in the academy and in the global activist community in recent years. Taking advantage of this boom in anarchist scholarship, Nathan J. Jun and Shane Wahl have compiled twenty-six cutting-edge essays on this timely topic in New Perspectives on Anarchism.
In Defense of Utilitarianism, C.L. Sheng provides a more intensive study of the Unified Utilitarian Theory , which he proposed in his previous work A New Approach to Utilitarianism . Sheng defends utilitarianism, particularly UUT, against the objections and attacks raised by nonutilitarians, showing it to be a viable ethical theory.
A growing literature looks at how the design of the electoral system shapes the voting behavior of politicians in parliaments. Existing research tends to confirm that in mixed-member systems the politicians elected in the single-member districts are more likely to vote against their parties than the politicians elected on the party lists. However, we find that in South Korea, the members of the Korean National Assembly who were elected on PR lists are more likely to vote against their party leadership (...) than the members elected in single-member districts (SMDs). This counterintuitive behavior stems from the particular structure of candidate selection and politicians' career paths. This suggests that any theory of how electoral systems shape individual parliamentary behavior needs to look beyond the opportunities provided by the electoral rules for voters to reward or punish individual politicians (as opposed to parties), to the structure of candidate selection inside parties and the related career paths of politicians.

In recent years, sequencing technologies have enabled the identification of a wide range of non-coding RNAs (ncRNAs). Unfortunately, annotation and integration of ncRNA data has lagged behind their identification. Given the large quantity of information being obtained in this area, there emerges an urgent need to integrate what is being discovered by a broad range of relevant communities. To this end, the Non-Coding RNA Ontology (NCRO) is being developed to provide a systematically structured and precisely defined controlled vocabulary for the (...) domain of ncRNAs, thereby facilitating the discovery, curation, analysis, exchange, and reasoning of data about structures of ncRNAs, their molecular and cellular functions, and their impacts upon phenotypes. The goal of NCRO is to serve as a common resource for annotations of diverse research in a way that will significantly enhance integrative and comparative analysis of the myriad resources currently housed in disparate sources. It is our belief that the NCRO ontology can perform an important role in the comprehensive unification of ncRNA biology and, indeed, fill a critical gap in both the Open Biological and Biomedical Ontologies (OBO) Library and the National Center for Biomedical Ontology (NCBO) BioPortal. Our initial focus is on the ontological representation of small regulatory ncRNAs, which we see as the first step in providing a resource for the annotation of data about all forms of ncRNAs. The NCRO ontology is free and open to all users, accessible at: http://purl.obolibrary.org/obo/ncro.owl. (shrink)
Is reducing large-scale intergroup conflict the business of corporations? Although large corporations can use their power and prominence to reduce intergroup conflict in society, it is unclear to what extent stakeholders support corporate Intergroup Responsibility. Study 1 showed that support for CIR correlates in theoretically meaningful ways with relevant economic, social, and moral attitudes, including fair market ideology, consumer support for corporate social responsibility, social dominance orientation, symbolic racism, and moral foundations. Studies 2 and 3 employed experimental designs to test (...) the hypothesis that business leaders who advocate for intergroup tolerance boost perceptions of corporations and their leaders as moral, just, and fair, which in turn, increases stakeholders’ support for CIR. We found support for this hypothesis across two highly publicized and contentious events related to racial conflict in the U.S.: The White supremacy rally in Charlottesville and the federal government’s announcement about the planned rescinding of the Deferred Action for Childhood Arrivals immigration policy. Specifically, exposing participants to real-world tweets by CEOs who advocated intergroup tolerance following these events increased participants’ support for CIR. This effect was mediated by heightened perceptions of corporations and their leaders as moral, just, and fair. Taken together, these findings enhance our understanding of the factors that shape stakeholders’ reactions to CIR; highlight intergroup conflict as an emerging arena for CSR; and illustrate the power of ethical intergroup leadership.

The DAMA project is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.N. In particular, the DAMA/LIBRA (Large sodium Iodide Bulk for RAre processes) set-up consists of highly radiopure NaI(Tl) detectors for a total sensitive exposed mass of ≃250 kg. Recent results, obtained by this set-up by exploiting the model independent annual modulation signature of Dark Matter (DM) particles, have confirmed and improved those obtained by the former DAMA/NaI experiment. (...) A model independent evidence for the presence of Dark Matter particles in the galactic halo is cumulatively obtained at 8.2 σ C.L. No systematics or side reactions able to account for the measured modulation amplitude and to contemporaneously satisfy all the many specific requirements of the signature have been found or suggested by anyone over more than a decade. An example of one of the many possible model dependent corollary quests for the candidate particles and for the related astrophysical, nuclear and particle physics scenarios is presented considering the whole cumulative exposure. Future perspectives are shortly addressed. (shrink)
This study explores both the negotiating styles and moral reasoning processes of business people and governmental officials in Taiwan, so as to provide a footing for outsiders when negotiating with Taiwanese over environmental concerns. Findings imply that Taiwanese business people and governmental officials can and will reason both at the conventional level and at the postconventional level of moral judgment. But, results of this study also indicate that Taiwanese negotiating styles do not necessarily match their levels of moral reasoning. With (...) respect to pollution concerns, Taiwanese seem unwillingly to accept responsibility as autonomous individuals. Instead, responsibility is accepted when mandated by the law. (shrink)
At Moore’s time, the main-stream ethical theory is the doctrine that pleasure alone is good as an end as held by the hedonistic utilitarianism. Moore, however, asserts that good, not composed of any parts, is a simple notion and indefinable, and naturalistic ethical theories, in particular hedonistic utilitarianism, interpret intrinsic good as a property of a single natural object---pleasure, which is also the sole end of life, thus violates naturalistic fallacy. Moore seems to believe that there exist things other than (...) pleasure that are also intrinsically good and has searched for them. But Moore has not clearly stated what these things are, nor has he given any justification for why they are intrinsically good. This paper discusses Moore’s arguments and difficulties of utilitarianism. With the subjectivistic utilitarian theory of value, Unified Utilitarian Theory (UTT) discards the classification of value into intrinsic and instrumental and proves to be exempt of all theexisting difficulties with utilitarianism related to pleasure, including naturalistic fallacy, vagueness of pleasure and sole end of life, double counting, etc. (shrink)
Molodtsov introduced 1999 the concept of soft set as a new mathematical tool for dealing with uncertainties that is free from the difficulties that have troubled the usual theoretical approaches. In this paper we apply the notion of soft sets by Molodtsov to ordered semigroups. The notions of soft ordered semigroup, soft ordered subsemigroup, soft left ideal, and left idealistic soft ordered semigroup are introduced, and various related properties are investigated.
