Systems which use parallel processing to speed up response times are normally required to be determinate. Parallel program schemata are formal models of parallel systems which serve to exactly define determinacy. Three variants of determinacy have frequently been used in the literature: Two “semantic” ones, which refer to the final contents of variables and to the sequences of contents, and a “syntactic” one, which is based upon the notion of conflict. Variants of determinacy can be derived with a universal definition of determinacy (as presented in [K73]) which uses a parameter, namely an equivalence relation on computations. Each of the above variants corresponds to a certain equivalence relation. The main aim of this paper is to investigate the role of “read-only”-operations, e.g. pure tests. Results of tests do not matter for both semantic forms of determinacy, whereas they are relevant for the syntactic form. We will snow that different variants of semantic and syntactic determinacy can be obtained by judging read-only operations as relevant or not.

The purpose of the study was to gain understanding of how character is understood in the New Zealand Rugby (NZR) ecology and how the Player Development Manager (PDM) in one Provincial Union (PU) negotiates, constructs and operationalizes interpretations of character within talent identification and development practices. The study design was informed by Bronfenbrenner’s ecological systems model of development and the methodology was case study. The participant in the study was the PDM who worked for one provincial rugby union and NZR. Data was gained using; interviews, document analysis and observations. An iterative strategy was employed when adopting the deductive and inductive analysis. The study found that across the NZR ecology there was no universal definition of character, or set of criteria used to assess players’ character. Within the NZR macrosystem there were formal policies that explicitly identified character as a value to be assessed. Yet, implicit understandings and assessment of character also existed. The PDM working in a microsystem constructed his understanding and assessment of character based on his experiences working with, and for, NZR (macrosystem) and the PU (exosystem) respectively, as well as drawing on his personal value set. The findings of this study are significant not only for rugby, in New Zealand and elsewhere, but they are relevant and topical for any selector, recruitment agent or coach who implicitly and explicitly (de)selects participants based on character.

The field of data governance is emerging globally. Although there is yet no universal definition of the field, the issue of data governance is important to governments, industries, institutions, and professionals across disciplines. This paper summarizes findings from a review of 50 data governance definitions from a cross-section of industries, institutions, and professional associations. Text analysis reveals varying definitions and levels of specificity, focus, and attitudes towards basic principles of control or prescription. Organizational culture is an additional factor likely reflected in semantics shaping the definitions. The paper makes recommendations for developing and designing definitions that are meaningfully aligned to the organization's mission and diverse stakeholders. The main contributions of the paper are 1) comprehensive summary of data governance definitions across industries; 2) role of specificity, focus, and attitudes underlying control; 3) framework to customize data governance definition to align with current data maturity and organizational mission and culture.

The search for a universal definition of death is a relatively new objective in human history, framed by complex biological, technological, and socio-political factors. While it is widely understood that “life” and “death” describe inverse states of being, what separates these two states has been vigorously debated by scientists, ethicists, and theologians. Far from merely an academic distinction, the definition of death has implications that extend to end-of-life healthcare, organ transplantation, and inheritance law. This review explores the historical and current definitions of death in the United States, the role of technological advances, and the resultant social and legal applications.

Abstract Background The primary role of the International Federation of Clinical Chemistry (IFCC) Committee on Clinical Application of Cardiac Bio-Markers (C-CB) is to provide educational materials about cardiac biomarker use, emphasizing high-sensitivity cardiac troponin assays. Content This mini-review, regarding high-sensitivity cardiac and point-of-care troponin assays, addresses 1) new IFCC C-CB/AACC Academy laboratory practice recommendations; 2) new and updated concepts from the Fourth Universal Definition of Myocardial Infarction; 3) the role of point-of-care assays in practice and research; 4) regulatory challenges concerning point-of-care assays; e) testing in the COVID-19 world. Summary Implementation of high-sensitivity cardiac troponin assays makes a difference now and into the future in clinical practice and research. Providing point-of-care high-sensitivity cardiac troponin assays and optimizing studies to allow clearance of these assays by regulatory agencies, in a timely fashion, may provide improved patient management and outcomes.

Abstract. As the criticism of the definition of the phenotype (i.e., clinical diagnosis) represents the major focus of the Research Domain Criteria (RDoC) initiative, it is somewhat surprising that discussions have not yet focused more on specific conceptual and procedural considerations of the suggested RDoC constructs, sub-constructs, and associated paradigms. We argue that we need more precise thinking as well as a conceptual and methodological discussion of RDoC domains and constructs, their interrelationships as well as their experimental operationalization and nomenclature. The present work is intended to start such a debate using fear conditioning as an example. Thereby, we aim to provide thought-provoking impulses on the role of fear conditioning in the age of RDoC as well as conceptual and methodological considerations and suggestions to guide RDoC-based fear conditioning research in the future.

Definition Of

The term ?business model' has recently attracted increased attention in the context of financial reporting and was formally introduced into the IFRS literature when IFRS 9 Financial Instruments was published in November 2009. However, IFRS 9 did not fully define the term ‘business model'. Furthermore, the literature on business models is quite diverse. It has been conducted in largely isolated fashion; therefore, no generally accepted definition of ?business model' has emerged. Therefore, a better understanding of the notion itself should be developed before further investigating its potential role within financial reporting. The aim of this paper is to highlight some of the perceived key themes and to identify other bases for grouping/organizing the literature based on business models. The contributions this paper makes to the literature are twofold: first, it complements previous review papers on business models; second, it contains a clear position on the distinction between the notions of the business model and strategy, which many authors identify as a key element in better explaining and communicating the notion of the business model. In this author's opinion, the term ‘strategy' is a dynamic and forward-looking notion, a sort of directional roadmap for future courses of action, whereas, ‘business model' is a more static notion, reflecting the conceptualisation of the company's underlying core business logic. The conclusion contains the author's thoughts on the role of the business model in financial reporting.

The advancement of European dress to the rest of the world was linked to the definition of civilization as “a stage of social development considered to be more advanced” and “polite and good-mannered”. The widespread of their fashion style in the 19th and 20th centuries influenced the way the rest of the world attire. The fashion trend and dressing style thus change the purpose of dressing through time. The dressing style in campuses especially in private institutions of higher learning is under particular scrutiny, as it is often said to be inappropriate for a learning environment. This study looked at the importance of moral education, and its role in implementing the dress code for students among university students especially between two types of university i.e. public university and private university. It looked on the dressing style of students, both male and female, and the factors that lead to their dressing pattern which is common among students. This study also advocated the students’ understanding of the content of dress codes in their learning institution and the role played by moral education in regard to dress code. The overall study highlighted students’ perception towards the implementation of the dress code and punishment in their learning institution. The methodologies used to carry out this study are questionnaires and interviews. This study will therefore ascertain the important of dress code among students at higher learning institution and the role of moral education in cultivating values in order to dress properly or decently. Key Words: moral education, dress code, higher learning institution, civilization.
