Objective To compare assessments of the decision-making competencies of psychiatric inpatients as provided by physicians, nurses, relatives and an assessment tool.Methods This study was carried out at the psychiatry clinic of Kocaeli University Hospital from June 2007 to February 2008. The decision-making competence of the 83 patients who participated in the study was assessed by physicians, nurses, relatives and MacCAT-T.Results Of the 83 patients, the relatives of 73.8% of them, including the parents of 47.7%, were interviewed during the study. A (...) moderately good consistency between the competency assessments of the nurses versus those of the physicians, but a poor consistency between the assessments of the physicians and nurses versus those of the patients’ relatives, was determined. The differences in the competency assessment obtained with the MacCAT-T versus the evaluations of the physicians, nurses and patients’ relatives were statistically significant.Conclusions Our findings demonstrate those physicians, nurses and the patients’ relatives have difficulty in identifying patients lacking decision-making competence. Therefore, an objective competence assessment tool should be used along with the assessments of physicians and nurses, both of whom can provide clinical data, as well as those of relatives, who can offer insights into the patient's moral values and expectations.

ObjectiveDignified care protects the patient’s rights and provides appropriate ethical care while improving the quality of nursing care. In this context, the opinions of nurses and patients who receive nursing care about dignified care are important. The aim of this study was to explore the opinions and experiences of Turkish patients and nurses about respectful care of human dignity.MethodsThis descriptive cross-sectional study was conducted in Turkey. Participants were inpatients at cardiology, neurology and neurosurgery clinics and nurses working in these clinics. (...) The data for the study were collected from face-to-face interviews using questionnaires. The percentages of characteristics and preferences of the participants were calculated, and the results were analysed using statistical tests.ResultsA total of 150 patients and 78 nurses participated in the study. The patients stated that the protection of their rights was the most important factor for dignified nursing care. The nurses stated that being careful to not expose the patients’ body and being respectful of the patients’ privacy were important in dignified nursing care. The age of the patient, duration of the disease, number of hospitalisations and length of time the nurses had been working at the clinic caused significant changes in the factors considered important in dignified care.ConclusionsOur findings provide a perspective on dignified care in the Turkish healthcare setting. There were some differences between patients and nurses in the factors considered important for dignified care. The discussion with patients and nurses related to care and practices that protect or detract from human dignity can provide insights to ethics. (shrink)

Background: It is stated that the communication and disease experiences of paediatric patients, especially paediatric oncology patients, with healthcare professionals are completely different from those of adults. Objective: The aim of this study was to determine the definitions of a good physician and good nurse provided by elementary school-age oncology patients. Research design: In this qualitative research, data were collected through semi-structured individual interviews. The data were evaluated thorough thematic analysis. Participants and research context: Eighteen children hospitalised due to cancer (...) in paediatric oncology and haematology clinics of a university hospital in Turkey. Ethical considerations: Permission to conduct the study was obtained from the Institution’s Ethics Committee. The objectives of this study were explained to the participants and families, and written consent was obtained from them. Also, participants were assured that necessary measures would be taken to protect their anonymity and confidentiality. Findings: The definitions of children were based on five main themes: interpersonal relationships, virtues, professional responsibility, security and individual characteristics. Conclusion: Children conveyed important messages to health professionals. They emphasised that a good physician and good nurse should communicate well, not only with themselves but also with their family. In addition, children were sensitive about health professionals who played with them and actively participated in the treatment by informing them about the disease. Meeting the expectations of children can be possible by improving the communication skills of physicians and nurses and by adding games and activities to the treatment and care plan. (shrink)

Nurses who attend patients with psychiatric disorders often encounter ethical dilemmas and experience difficulties in making the right decision. The present study aimed to evaluate the decisions of psychiatric nurses regarding their duty to warn third parties about the dangerousness of the patient, the need for compulsory hospitalization, and the competence of patients. In total, 111 nurses working in the field of psychiatry in Turkey completed a questionnaire form consisting of 33 questions. The nurses generally assessed the decision-making competency of (...) the patient correctly. However, their decisions regarding whether the patient should be compulsorily hospitalized and their understanding of their duty to warn/protect were less consistent. A significant relationship was found between the decisions of the psychiatric nurses and their work experience, them having children, and them having postgraduate education in psychiatric nursing. The nurses stated their desire to be part of the team that decided on ethical problems in psychiatry. (shrink)

The aim of this study was to assess attitudes of intensive care nurses to selected ethical issues related to end-of-life decisions in paediatric intensive care units. A self-administered questionnaire was distributed in 2005 to intensive care nurses at two different scientific occasions in Turkey. Of the 155 intensive care nurse participants, 98% were women. Fifty-three percent of these had intensive care experience of more than four years. Most of the nurses failed to agree about withholding (65%) or withdrawing (60%) futile (...) treatment. In addition, 68% agreed that intravenous nutrition must continue at all costs. In futile treatment cases, the nurses tended to leave the decision to parents or act maternalistically. The results showed that intensive care nurses could ignore essential ethical duties in end-of-life care. We suggest that it is necessary to educate Turkish intensive care nurses about ethical issues at the end of life. (shrink)

How is a philosophical tradition created? What role does literary biography play in the formation of intellectual reception history? Through a detailed analysis of the lives and works of post-Avicennan philosophers, this monograph traces the intellectual history and development of the Avicennan tradition from the fifth/eleventh to the eighth/fourteenth century. Section 1 investigates the genres of Arabo-Islamic biobibliographical and prosopographical writings as a source for the history of Arabic philosophy, delineating their literary topoi, the construction of philosophical authority, and the (...) relationship of Sunnī and Twelver-Šīī Islam to Aristotelian logic and philosophy. Section 2 presents fourteen discrete biobibliographical studies with a critical inventory of the works, including those written in the neglected exegetical genres of commentary, supercommentary, gloss, and supergloss, of Avicenna's immediate disciples and the following generations of philosophers who created the Avicennan philosophical heritage in the Islamicate world.--Provided by Publisher.

Even though Corporate Social Responsibility (CSR) has become a widely accepted concept promoted by different stakeholders, business corporations' internal strategies, known as corporate self-regulation in most of the weak economies, respond poorly to this responsibility. Major laws relating to corporate regulation and responsibilities of these economies do not possess adequate ongoing influence to insist on corporate self-regulation to create a socially responsible corporate culture. This book describes how the laws relating to CSR could contribute to the inclusion of CSR principles (...) at the core of the corporate self-regulation of these economies in general, without being intrusive in normal business practice. It formulates a meta-regulation approach to law, particularly by converging patterns of private ordering and state control in contemporary corporate law from the perspective of a weak economy. It proposes that this approach is suitable for alleviating regulators' limited access to information and expertise, inherent limitations of prescriptive rules, ensuring corporate commitment, and enhance the self-regulatory capacity of companies. This book describes various meta-regulation strategies for laws to link social values to economic incentives and disincentives, and to indirectly influence companies to incorporate CSR principles at the core of their self-regulation strategies. It investigates this phenomenon using Bangladesh as a case study. (shrink)

The semantic of the terms “sustainable development” and “corporate social responsibility” have changed over time to a point where these concepts have become two interrelated processes for ensuring the far‐reaching development of society. Their convergence has given dimension to the environmental and corporate regulation mechanisms in strong economies. This article deals with the question of how the ethos of this convergence could be incorporated into the self‐regulation of businesses in weak economies where nonlegal drivers are either inadequate or inefficient. It (...) proposes that the policies for this incorporation should be based on the precepts of meta‐regulation that have the potential to hold force majeure, economic incentives, and assistance‐related strategies to reach an objective from the perspective of weak economies.

The convergence of corporate social responsibility (CSR) and corporate governance (CG) has changed the corporate accountability mechanism. This has developed a socially responsible ‘corporate self-regulation’, a synthesis of governance and responsibility in the companies of strong economies. However, unlike in the strong economies, this convergence has not been visible in the companies of weak economies, where the civil society groups are unorganised, regulatory agencies are either ineffective or corrupt and the media and non-governmental organisations do not mirror the corporate conscience. (...) Using the case of Bangladesh, this article investigates the convergence between CSR and CG in the self-regulation of companies in a less vigilant environment. (shrink)

A gossip protocolGossip protocol is a procedure for sharing secrets in a network. The basic action in a gossip protocolGossip protocol is a telephone call wherein the caller and the callee exchange all the secrets they know. An agent who knows all secrets is an expert. The usual termination condition is that all agents are experts. Instead, we explore some protocols wherein the termination condition is that all agents know that all agents are experts. We call such agents super experts. (...) Additionally, we model that agents who already know that all agents are experts, do not make and do not answer calls. We also model that such protocols are common knowledgeCommon knowledge among the agents. We investigate conditions under which such gossip protocolsGossip protocol terminate, both in the synchronous case, where there is a global clock, and in the asynchronous case, where there is not. We show that a protocol with missed calls can terminate faster than the same protocol without missed calls. (shrink)

Although managers spend over twenty percent of their time in conflict management, organization theorists have provided very few guidelines to help them do their job ethically. This paper attempts to provide some guidelines so that organizational members can use the styles of handling interpersonal conflict, such as integrating, obliging, dominating, avoiding, and compromising, with their superiors, subordinates, and peers ethically and effectively. It has been argued in this paper that, in general, each style of handling interpersonal conflict is appropriate if (...) it is used to attain organization''s proper end. (shrink)

Conceptual metaphors have received much attention in research on discourse about infectious diseases in recent years. Most studies found that conceptual metaphors of war dominate media discourse about disease. Similarly, a great deal of research has been undertaken on the new coronavirus, i.e., COVID-19, especially in the English news discourse as opposed to other languages. The present study, in contrast, analyses the conceptual metaphors used in COVID-19 discourse in French-language newspapers. The study explored the linguistic metaphors used in COVID-19 discourse (...) in these newspapers and conceptual metaphors that underlie and motivate them, using a conceptual metaphor theory framework (CMT). Therefore, two North African French-language newspapers, namely Libération, published in Morocco, and La Presse de Tunisie, published in Tunisia, formed the corpus of the current study. The results showed that the most frequent framing of COVID-19 was in terms of WAR, followed by DISASTER and KILLER, respectively. (shrink)

Sport is viewed as a multidimensional phenomenon. Most countries,including Muslim nations, invest heavily in sports to ensure the participationof their citizens both for recreational and competitive purposes. Indeed, theinvolvement of Muslim countries in significant multi-sport events such as theCommonwealth, the Asian, and the Olympic Games are inevitable. Therefore,a proper projection should be given to Muslim athletes as their participationreflects the identity and culture of Muslim civilizations. To date, the issue ofMuslim athlete’s involvement in sports from the notion of Islamization hasyet (...) to be elucidated by any scholar. This paper aims to scrutinize the sportssociology as an academic discipline in the Muslim majority society context.It also views the philosophy of sports participation and the dilemma facedby Muslims in sports under the light of al- Qur’ān, and Hadith. In obtainingrelevant information for this paper, we employed qualitative content analysisfrom various literature. In conclusion, this discourse of sport, Islam, and society has potentially triggered the new social movement that accommodated the needs of the Muslim community towards sports participation and physical activity.

This article aims to draw a theoretical framework to discuss the role of religion in utopia's appeal to transcendence in Turkish literature. This aim entails interrogating the intricate relation between utopia and religion in order to demonstrate how religious discourse functions as a transcendent organizing principle in Turkish utopian vision. The employment of religious discourse in utopia often generates problematic moments in which utopia attains a transcendent position and comes closest to its sibling term, dystopia. This article seeks to identify (...) and describe this position of transcendence in Turkish utopia by resorting to Deleuzian distinction between the two types of utopia: “utopia of transcendence,” oriented toward authoritarianism, and “utopia of immanence,” oriented toward revolution. In so doing, it will engage with three early works from the Second Constitutional Period, Ruşeni Barkın's Müslümanların Gaye-i Hayâliyesi, İsmail Gaspıralı's Darürrahat Müslümanları, and Molla Davudzade's Rüyada Terakki ve Medeniyet-i İslamiyeyi Rü‘yet.

Singapore's long-serving People's Action Party government suffered from a major electoral setback in the 2011 general election and subsequent by-elections. The high-growth population policy, underpinned by the influx of migrants and foreign workers, has strongly fuelled the groundswell of public discontent and is commonly perceived to have contributed to widening income disparities, wage stagnation, and cost of living pressures. This article attempts to make sense of the PAP leadership's dogged commitment to the high-growth population policy despite the electoral backlashes and (...) policy criticisms by prominent public intellectuals and others closely connected to the PAP establishment. It considers Singapore's high-growth population policy and widening income disparity within the context of the authoritarian developmental state's shift away from the social compact. The article also examines the impact of widening income inequality and other policy lapses on the legitimacy of the PAP government as the clamor for a renewed social compact based on gathers momentum in the repoliticized polity.

(...) It is the first book to explore the issues and challenges related to the development of effective social audit regulation. (shrink)

Using intelligent software agents in the world of e-commerce may give rise to many difficulties especially with regard to the validity of agent-based contracts and the attribution of liability for the actions of such agents. This paper thus critically examines the main approaches that have been advanced to deal with software agents, and proposes the gradual approach as a way of overcoming the difficulties of such agents by adopting different standards of responsibility depending whether the action is done autonomously by (...) an unattended software, or whether it is done automatically by an attended software. Throughout this paper, it is argued that the introduction of “one size” regulation without sufficient consideration of the nature of software agents or the environments in which they communicate might lead to a divorce between the legal theory and technological practice. It is also concluded that it is incorrect to deal with software agents as if they were either legal persons or nothing without in any way accounting for the fact that there are various kinds of such agents endowed with different levels of autonomy, mobility, intelligence, and sophistication. However, this paper is not intended to provide the final answer to all problematic questions posed by the emergence of intelligent software agents, but is designed to provide some kind of temporary relief until such agents reach a more reliable and autonomous level whereby law begins to regard them, rather than their users, as the source of the relevant action.

Background: Moral distress and workplace bullying are important issues in the nursing workplace that appear to affect nurse’s burnout. Aim: To investigate the relationship between moral distress and burnout in Iranian nurses, as mediated by their perceptions of workplace bullying. Ethical considerations: The research was approved by the committee of ethics in research of the Urmia University of Medical Sciences. Method: This is a correlation study using a cross-sectional design with anonymous questionnaires as study instruments. Data were collected from 278 (...) nurses from five teaching hospitals in Urmia, the capital of Western Azerbaijan, northwest of Iran. Structural equation modeling and bootstrapping procedures were employed to recognize the mediating role of their perceptions of workplace bullying. Results: The mean score of moral distress, burnout, and the Negative Acts Questionnaire-Revised Scale among the participants were 91.02 ± 35.26, 79.9 ± 18.27, and 45.4 ± 15.39, respectively. The results confirmed our hypothesized model. All the latent variables of study were significantly correlated in the predicted directions. The moral distress and bullying were significant predictors of burnout. Perception of bullying partially mediated the relationship between moral distress and burnout. The mediating role of the bullying suggests that moral distress increases burnout, directly and indirectly. Conclusion: Nursing administrators should be conscious of the role of moral distress and bullying in the nursing workplace in increasing burnout. (shrink)

An amalgamation base p in a simple theory is stably definable if its canonical base is interdefinable with the set of canonical parameters for the ϕ-definitions of p as ϕ ranges through all stable formulae. A necessary condition for stably definability is given and used to produce an example of a supersimple theory with stable forking having types that are not stably definable. This answers negatively a question posed in [8]. A criterion for and example of a stably definable amalgamation (...) base whose restriction to the canonical base is not axiomatised by stable formulae are also given. The examples involve generic relations over non CM-trivial stable theories. (shrink)

The question of liability in the case of using intelligent agents is far from simple, and cannot sufficiently be answered by deeming the human user as being automatically responsible for all actions and mistakes of his agent. Therefore, this paper is specifically concerned with the significant difficulties which might arise in this regard especially if the technology behind software agents evolves, or is commonly used on a larger scale. Furthermore, this paper contemplates whether or not it is possible to share (...) the responsibility with these agents and what are the main objections surrounding the assumption of considering such agents as responsible entities. This paper, however, is not intended to provide the final answer to all questions and challenges in this regard, but to identify the main components, and provide some perspectives on how to deal with such issue.

The effort to align MathML 3 and OpenMath has led to a realisation that (pragmatic) MathML’s condition and domainofapplication elements, when used with quantifiers, do not have a neat expression in OpenMath. This paper analyzes the situation focusing on quantifiers and proposes a solution, via six new symbols. Two of them fit completely within the existing OpenMath structure, and we place them in the associated quant3 CD. The others require a generalization of OMBIND. We also propose, logically separately but in (...) the same area, a quant2 CD with existsuniquely, commonly written ∃!, and the ‘fusion’ symbol existsuniquelyin. In a second step we generalize the solution to the phenomenon of big operators that MathML 2 implicitly provides but which do not have a direct counterpart in the OpenMath CDs. (shrink)

Studies on difficulties in understanding scientific terms have shown that the problem is more serious among non-Western learners. The main reasons for this are the learners' pre-existing knowledge of scientific terms, their native language incommensurability with Western languages, and the polysemy of the words used to denote scientific concepts. The current study is an analysis of the conceptualisation of scientific concepts in two culturally different languages, i.e. Arabic and French, which represent a non-Western language and a Western language respectively. Physics (...) concepts which are considered as some of the most challenging concepts for non-Western languages (Loo 2005; Aranador 2005) were selected for analysis. To this end, the terms that refer to two physics concepts, "weight" and "mass" in Arabic وَزْن (wazn) and كُتْلَة (kutla) and in French poids and masse were semantically analysed. The analysis of the concepts in both languages is informed by the prototype theory by Rosch (1973; 1975), idealised cognitive models (ICMs) by Lakoff (1987), and conceptual metaphor and conceptual metonymy by Lakoff and Johnson (2003). The data for analysis were retrieved from two comparable Arabic and French corpora, namely the ArabiCorpus and the Concordancier-Corpus Français. The results suggest that there are both similarities and differences between the Arabic and French concepts in terms of meanings, prototypes, and metaphorical as well as metonymic semantic extensions. These findings support the argument that the human conceptual system is related to our environmental and cultural experiences and also importantly, validate previous claims on the need for educators to be cognizant of the culturally relevant meanings of scientific words found in everyday language that may impede learners' understanding of scientific concepts.
