Introduction: Maintaining patient dignity in a caregiving environment is one of the most important moral responsibilities for caregivers. Nonetheless, there are vulnerable groups, specifically teenagers, who in their final stages of life are prone to their dignity being threatened. Moreover, dignity is an abstract concept and there is no studies done on teenagers’ dignity in the final stages of life available in Iran.Purpose: The purpose of this study is to describe the caregivers’ experiences regarding teenagers’ dignity in the final stages (...) of life.Research design: This study is a descriptive phenomenological qualitative research project. The data was collected using deep individual and semi-structured interviews as well as taking notes. The Colaizzi analysis method was used to analyze the data.Participants and research context: 22 caregivers working with teenagers in the final stages of life in a public health centers in Iran who had the criteria to enter the study were selected using a purposeful sampling method and invited to join the study from August 2018 to June 2019. The sampling continued until data saturation.Findings: The findings of the present study were presented in the form of three main themes including “private,” “respecting individual identity,” and “attention to teenagers’ needs” and an additional eight categories.Ethical Considerations: The study’s protocol was approved by the Research Ethics Committee of the Shiraz University of Medical Sciences and all ethical principles were followed throughout the study.Discussion and conclusion: Based on the present study from the caregivers’ point of view, teenagers in their final stages of life required to be cared for and taught in an environment that their privacy was maintained and their individual identity was respected as well as getting attention from the caregivers and companions. In such situations, the teenagers felt calm and their dignity was maintained; therefore, providing a cultural, professional, and organizational setting where all the components of maintaining dignity in teenagers are supported and prioritized is necessary.

Has the theory of rationality as ‘openness to criticism’ solved the problem of ‘rational belief in reason’? This is the main question the present article intends to address. I respond to this question by arguing that the justified true belief account of knowledge has prevented Karl Popper’s critical and William Bartley’s pan-critical rationalism from solving the problem of rational belief in reason. To elaborate this response, the article presents its arguments in three stages: First, it argues that the idea of (...) objective knowledge as justified true belief leads to the equation of objective knowledge with justification. Hence, if we base the theory of critical rationalism, as openness to criticism, upon such a conception of knowledge, our theory of rationality involves in infinite regress of proofs. Second, it argues that Popper describes critical rationalism as an ‘irrational attitude’ of openness to criticism because the rationalist cannot justify his belief in reason by argument or experience. Thus, since Popper assumes that ‘a belief in reason’ must be justified in order to be ‘rational’ he cannot lead to a solution for the problem of rational belief in reason. Third, it argues that, like Popper’s critical rationalism, Bartley’s pan-critical rationalism originates in the justified true belief account of knowledge, however, not because Bartley defines critical rationalism as irrational faith in reason, but because his theory does not tell us how an ‘open’ belief in reason is to be refuted logically. The reason for this failure is that Bartley uses Popper’s epistemology of science to define the conception of criticism. While Popper and Bartley are recognized as the non-justificationist philosophers of science and rationality, this article tries to reveal that the idea of objective knowledge as justified true belief has prevented them from showing how ‘a rational belief in reason’ can be defended by argument. The article also briefly shows the consequence of this study for a notable change in the logical foundations of science. (shrink)

BackgroundMoral distress is one of the most important problems that nurses face in their care of patients. Various studies have reported the frequency and severity of moral distress in nurses. However, to date, a comprehensive study that shows the results of these research across the world was not found, therefore due to the importance of this issue, its role in the health of nurses and patients, and the lack of general statistics about it worldwide, the present study was conducted to (...) determine the frequency and severity of moral distress in nurses through a systematic review and meta-analysis.MethodsIn this review study, searching national and international databases of SID, MagIran, IranMedex, IranDoc, Google Scholar, Embase, ScienceDirect, Scopus, CINHAL, PubMed, and Web of Science between 2005 and February 2020 were extracted. The random-effects model was used for analysis, and the heterogeneity of studies with the I2 index was investigated. Data were analyzed using Comprehensive Meta-Analysis.ResultsThe frequency of moral distress in 9 articles with a sample size of 1576 persons was 1.7 ± 0.5 from, in 13 articles with a sample size of 1870 persons, 3.07 ± 0.1 from, in 6 articles with a sample size of 1316 persons, 3.2 ± 0.29 from, in 18 articles with a sample size of 1959 persons, 4.6 ± 0.518 from and in 35 articles with a sample size of 3718 persons, 81.1 ± 4.6 from, and the severity of moral distress in 4 articles with a sample size of 1116 persons, 1.7 ± 0.37 from, in 5 articles with a sample size of 1282 persons, 2.6 ± 0.28 from, in 5 articles with a sample size of 944 persons, 3.9 ± 0.63 from and in 8 articles with a sample size of 901 persons was 82.3 ± 5.4.ConclusionThe results of this study showed that the frequency and severity of moral distress in nurses are high and are a serious problem in nurses. Therefore, policymakers in this field should consider its role in the health of nurses and patients. (shrink)

BackgroundDiscrimination in health care is an international challenge and a serious obstacle to justice and equality in health.Research objectiveThe purpose of this study was to design a grounded theory of discrimination in health care based on the experiences and perceptions of Iranian healthcare providers and patients.Research designThis qualitative study was conducted using by the grounded theory method.Participants and research contextData were collected through semi-structured interviews with 18 healthcare providers including 11 nurses, two physicians, two nurse’s assistants, and three patients in (...) two general hospitals in Tehran, Iran. Participants were selected through purposeful sampling and analyzed simultaneously using the Corbin and Strauss (2015) approach.Ethical considerationsThe study was approved by the Research Ethics Committee of the University of Social Welfare and Rehabilitation Sciences (Ethics code: IR.USWR.REC.1398.023). Also, after explaining the objectives of the study, all the participants completed and signed the written consent form.FindingsThe “culture of discrimination” was the study’s core category, reflecting the nature of discrimination in health care. The theory of “culture of discrimination in health care” is the result of five main categories: “individual social stimuli,” “culture of discrimination,” “unintentional discrimination,” “conflict with discrimination,” and “dissatisfaction with discriminatory behavior.” These categories cover the underlying factors, strategies, and outcomes of the discrimination process in health care.DiscussionThe results of the study showed that nurses and other health care providers experience unintentional discrimination. Unintentional discrimination refers to discriminatory behaviors and practices of health care providers.ConclusionThe theory of culture of discrimination in health care can be used as a practical guide to describe and understand the role of health care providers, especially nurses. Further studies with a quantitative approach to applying this theory in medical settings are recommended. (shrink)

A many-valued modal logic, called linear abelian modal logic \(\rm {\mathbf{LK(A)}}\) is introduced as an extension of the abelian modal logic \(\rm \mathbf{K(A)}\). Abelian modal logic \(\rm \mathbf{K(A)}\) is the minimal modal extension of the logic of lattice-ordered abelian groups. The logic \(\rm \mathbf{LK(A)}\) is axiomatized by extending \(\rm \mathbf{K(A)}\) with the modal axiom schemas \(\Box(\varphi\vee\psi)\rightarrow(\Box\varphi\vee\Box\psi)\) and \((\Box\varphi\wedge\Box\psi)\rightarrow\Box(\varphi\wedge\psi)\). Completeness theorem with respect to algebraic semantics and a hypersequent calculus admitting cut-elimination are established. Finally, the correspondence between hypersequent calculi and axiomatization (...) is investigated. (shrink)

Background and objectivesThe study of brain functional connectivity alterations in children with Attention-Deficit/Hyperactivity Disorder has been the subject of considerable investigation, but the biological mechanisms underlying these changes remain poorly understood. Here, we aim to investigate the brain alterations in patients with ADHD and Typical Development children and accurately classify ADHD children from TD controls using the graph-theoretical measures obtained from resting-state fMRI.Materials and methodsWe investigated the performances of rs-fMRI data for classifying drug-naive children with ADHD from TD controls. Fifty (...) six drug-naive ADHD children and 56 age matched TD controls were included in this study. The graph measures extracted from rs-fMRI functional connectivity were used as features. Extracted network-based features were fed to the RFE feature selection algorithm to select the most discriminating subset of features. We trained and tested Support Vector Machine, Random Forest, and Gradient Boosting using Peking center data from ADHD-200 database to classify ADHD and TD children using discriminative features. In addition to the machine learning approach, the statistical analysis was conducted on graph measures to discover the differences in the brain network of patients with ADHD.ResultsAn accuracy of 78.2% was achieved for classifying drug-naive children with ADHD from TD controls employing the optimal features and the GB classifier. We also performed a hub node analysis and found that the number of hubs in TD controls and ADHD children were 8 and 5, respectively, indicating that children with ADHD have disturbance of critical communication regions in their brain network. The findings of this study provide insight into the neurophysiological mechanisms underlying ADHD.ConclusionPattern recognition and graph measures of the brain networks, based on the rs-fMRI data, can efficiently assist in the classification of ADHD children from TD controls.

In recent years, research on morality in organizational life has begun to examine how organizational conduct comes to be socially constructed as having failed to comply with a community’s accepted morals. Researchers in this stream of research, however, have paid little attention to identifying and theorizing the key actors involved in these social construction processes and the types of accounts they construct. In this paper, we explore a set of key structural and cultural dimensions of apparent noncompliance that enable us (...) to distinguish between four categories of actors who engage in constructing the label of moral failure: dominant insiders, watchdog organizations, professional members, and publics. The analysis further clarifies which category of actor is more likely to succeed in constructing the label of moral failure under which circumstances, and what accounts they are likely to use, namely scapegoating, prototyping, shaming, and protesting.

Utilizing a pre-experimental pre-test post-test design, this study investigated the effect of an authentic audio-visual American sitcom on the intercultural sensitivity and intercultural effectiveness of a sample of male and female upper-intermediate English students. To this aim, 34 Iranian EFL students were selected through convenient non-random sampling. In order to assure the participants' homogeneity in English proficiency, the selected students were given the Oxford Quick Placement Test prior to the intervention. Over a 10-week period, the participants were presented with nearly (...) 30-min-long episodes of Friends in a flipped context, two episodes every week uploaded to the accompanying website. An online 10-item quiz on the day of watching and a next-day meeting were held. During the online discussion meetings, the participants discussed cultural questions tailored to the aims of the study. The required data were collected through the administration of the intercultural sensitivity scale and intercultural effectiveness scale in pre- and post-test assessments. The analyses of the data indicated that both ICS and ICE improved significantly during the intervention. However, ICS indicated more improvement. In addition, a semi-structured interview was administered to the participants to examine their perception of the flipped classroom experience. Having analyzed the data using MAXQDA 2020, some significant themes emerged which are reported. On the whole, the participants portrayed positive attitudes toward using technology in flipped classes. The educational and practical implications are discussed. (shrink)

ABSTRACT:Reports of widespread misconduct in organizations have become sadly commonplace. Sexual abuse in the Catholic Church, accounting fraud in large corporations, and physical and sexual harassment in the military implicate not only the individuals involved, but the organizations and fields in which they happened. In this paper we describe such situations as instances of “moral collapse” and develop a multi-level theory of moral collapse that draws on institutional theory as its central orienting lens. We draw on institutional theory because of (...) its explicit concern with the relationships among individual beliefs and actions, the organizations within which they occur, and the collective social structures in which norms, rules and beliefs are anchored. Our theory of moral collapse has two main elements. First, we argue that morality in organizations is embedded in nested systems of individuals, organizations and moral communities in which ideology and regulation flow “down” from moral communities through organizations to individuals, and moral ideas and influence flow “upward” from individuals through organizations to moral communities. Second, we argue that moral collapse is associated with breakdowns in these flows, and explore conditions under which such breakdowns are likely to occur. (shrink)

Over the last decade, scholars across the wide spectrum of the discipline of sociology have started to reengage with questions on morality and moral phenomena. The continued wave of research in this field, which has come to be known as the new sociology of morality, is a lively research program that has several common grounds with scholarship in the field of business ethics. The aim of this thematic symposium is to open constructive dialogues between these two areas of study. In (...) this introductory essay, we briefly present the project of the new sociology of morality and discuss its relevance for business ethics. We also review the contributions to this thematic symposium and identify four specific domains where future research can contribute to fruitful dialogues between the two fields. (shrink)

In this article, we first provide a modified definition of SuperHyperGraphs (SHG) and we call it Restricted SuperHyperGraphs (R-SHG). We then generalize the R-SHG to the neutrosophic graphs and then define the corresponding trees. In the following, we examine the Helly property for subtrees of SuperHyperGraphs.

Dignity is the most fundamental right of every human being, patients in particular.

In this paper, we consider a collection of filters of a BL-algebra A. We use the concept of congruence relation with respect to filters to construct a uniformity which induces a topology on A. We study the properties of this topology regarding different filters. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim).

In this paper, we consider a collection of filters of a BL-algebra A. We use the concept of congruence relation with respect to filters to construct a uniformity which induces a topology on A. We study the properties of this topology regarding different filters.

In this paper we introduce n -fold implicative basis logic and the related algebras called n -fold implicative BL-algebras. Also we define n -fold implicative filters and we prove some relations between these filters and construct quotient algebras via these filters.

This paper scrutinizes the dialogical character of knowledge from the perspectives of Hegel’s and Davidson’s philosophies. First, it outlines their analogous trains of thought, particularly their “anti-representational” and “intersubjective” accounts of knowledge. Second, it draws a parallel between the two by discussing their contrasting views of the structure and goal of knowledge, showing that while Davidson advocates an open-ended, scheme-less empirical knowledge, Hegel maintains the notion of a (universal-rational) scheme and a goal-oriented dialectical process in which “the true is the (...) whole.” This section then critically traces their underlying disagreement to their divergent views on the nature of meaning, language, and thought. Finally, it argues that their views can be seen as complementary to two versions of dialectic, showing that while Hegel’s approach, akin to Platonic dialectic, focuses on the self-contained and “Truth”-oriented “negotiational” movement of ideas, Davidson’s, reminiscent of Socratic elenchus, emphasizes the truth-oriented ‘conversational’ interaction of subjects exchanging concepts.

This qualitative research study with a content analysis approach aimed to explore families’ experiences of an organ donation request after brain death. Data were collected through 38 unstructured and in-depth interviews with 14 consenting families and 12 who declined to donate organs. A purposeful sampling process began in October 2009 and ended in October 2010. Data analysis reached 10 categories and two major themes were listed as: 1) serenity in eternal freedom; and 2) resentful grief. The central themes were peace (...) and honor versus doubt and regret. The findings indicated that the families faced with an organ donation request of a brain-dead loved one experienced a lasting effect long after the patient's demise regardless of their decision to donate or refusal to donate. In conclusion, this study highlights the importance of family support and follow-up in an efficient healthcare system aimed at developing trust with the families and providing comfort during and after the final decision.

Contrary to common misconceptions, today's logic is not devoid of existential import: the universalized conditional ∀ x [S→ P] implies its corresponding existentialized conjunction ∃ x [S & P], not in all cases, but in some. We characterize the proexamples by proving the Existential-Import Equivalence: The antecedent S of the universalized conditional alone determines whether the universalized conditional has existential import, i.e. whether it implies its corresponding existentialized conjunction.A predicate is an open formula having only x free. An existential-import predicate (...) Q is one whose existentialization, ∃ x Q, is logically true; otherwise, Q is existential-import-free or simply import-free.How abundant or widespread is existential import? How abundant or widespread are existential-import predicates in themselves or in comparison to import-free predicates? We show that existential-import predicates are quite abundant, and no less so than import-free predicates. Existential.. (shrink)

Next SectionPurpose The importance of recognising patient dignity has been realised in recent years. Despite being a central phenomenon in medicine, dignity is a controversial concept, the definition of which in healthcare centres is influenced by a multitude of factors. The aim of this study was to explore the perspective of Iranian patients on respect for their dignity in healthcare centres. Methods With the use of purposeful sampling, 20 patients were interviewed over an 11-month period in three educational hospitals affiliated (...) with the government. They were questioned about experiences related to respect for their dignity during their hospital encounter. Data were processed by qualitative content analysis. Results Data analysis identified nine categories and four themes. Respondents expressed their expectations and attitudes about dignity by the following themes: seeking a haven; disrespecting privacy; communicating in a vacuum; and disregard for secondary caregivers. They described how respect for their privacy, effective communication, access to facilities, and a regard for the requirements of their companions made them feel that their dignity had been conserved. Conclusions The findings indicate that almost no patient is satisfied with the quality of services with respect to maintenance of their dignity. Regardless of their hospital location and state of health, most participants had common complaints. These findings agree with the literature and confirm that grounds should be provided for conserving dignity in the healthcare system. To reach this goal, healthcare professionals should be aware of the factors that violate or preserve dignity from the patient's perspective. (shrink)

In recent philosophical analysis of religious experience and discussion on the relation of beliefs and experiences, Ninian Smart is said to be, amongst such other philosophers as Katz and Hick, a maximal constructivist. Distinguishing theistic and non-theistic contexts of experiences, Smart suggests a two poles theory of religious experience, and draws attention to different levels of interpretation. He holds that cultural-religious contexts, including religious beliefs, influence religious experience, but it is not led to fully determine experience. Accordingly, he takes a (...) position between essentialism and maximal constructivism. This position could call minimal constructivism. (shrink)

Background:Despite the growing importance of spiritual care, the delivery of spiritual care is still an area of disagreement among healthcare providers.Objective:To develop a grounded theory about spiritual care delivery based on Iranian nurses’ perceptions and experiences.A grounded theory approach:A qualitative study using the grounded theory approach.Participants and research context:Data were collected through holding 27 interviews with 25 participants. The study setting was the Imam Khomeini Hospital Complex. Sampling was started purposively and continued theoretically. Data analysis was performed by the method (...) proposed by Strauss and Corbin.Ethical consideration:The study was approved by the Ethics Committee of Tarbiat Modares University and the agreement of the administrators of the study setting was got before starting the study.Results:The core category of the study was “Trust building” which reflected the nature of spiritual care delivery by nurses. Trust building was the result of eight main categories or strategies including creating a positive mentality at hospital admission, understanding patients in care circumstances, having a caring presence, adhering to care ethics, developing meaningful relationships, promoting positive thinking and energy, establishing effective communication with patients, and attempting to create a safe therapeutic environment. Poor interprofessional coordination negatively affected this process while living toward developing greater cognizance of divinity and adhering to the principles of professional ethics facilitated it. The outcome of the process was to gain a sense of partial psychological security.Conclusion:The “Trust building” theory can be used as a guide for describing and expanding nurses’ roles in spiritual care delivery, developing care documentation systems and clinical guidelines, and planning educational programs for nursing students and staff nurses.

Nursing, a scientific and practical discipline, faces continuing challenges of finding new direction in order to decipher its core values and develop current ethical codes for nursing practice. In 2009–10, 28 nurses were purposely selected and interviewed using a semi-structured format in focus groups and individually. Thematic Content Analysis helped explore the perception of Iranian nurses on ethical values in patient care. Seven major themes emerged: respect for dignity, professional integrity, professional commitment, developing human relationships, justice, honesty, and promoting individuals (...) and the nursing profession. Iranian nurses revealed a unique and culture-based set of ethical values. This study found that Iranian nurses place a greater emphasis on preserving the dignity of those accompanying the patient and in showing regard for patients' religious beliefs in a gender appropriate environment.

Dignity is a human right and a base for human health. This right must be observed in work environments as a moral obligation. This qualitative study aimed to understand nurses’ experiences of violation of their dignity at work and to explore its dimensions. The participants were 15 nurses working in two hospitals in Tehran. The data were collected through 26 unstructured interviews and analyzed using content analysis. The dimensions of violation were ‘irreverence’, including experiences of abuse and violence, humiliation, and (...) being ignored; ‘coercion and violation of autonomy’, consisting of the control of relationships, lack of privacy, rigidness, and imposition; ‘ignoring professional and scientific ability’, indicating impossibilities in applying nurses’ knowledge; and ‘denying the value of nurse/care’, being the theme that verified the dominance of treatment/cure and lack of recognition of care value. Health systems should take the promotion of the nurses’ dignity into account through providing a dignified work environment. (shrink)

Introduction: Maintaining dignity is one of patients is one of the main ethical responsibilities of caregivers. However, in many cases, the dignity of patients, especially autistic teenagers is not maintained. The extent to which dignity needs are met for this group within the Iranian care system is difficult to determine as dignity is an abstract concept, and there are few related research studies reported. Objectives: The objective of this study is to find out caregivers perspectives on dignity in teenagers with (...) autistic spectrum disorder. Research design: This study uses a qualitative research design. The data were collected through individual, semi-structured interviews and field notes developed during the interviews. In order to analyze the data, qualitative conventional content analysis was used. Participants and research context: In all, 16 professional caregivers for autistic teenagers working in public hospitals were recruited based on a targeted sampling method to reach data saturation from February 2016 to July 2017. Findings: The findings of this study were presented in three main themes, “privacy,” “respecting individual identity,” and “comprehensive support,” and 11 categories. Ethical consideration: This study’s protocol was approved by the Research Ethics Committee of medical universities located in Southeast of Iran and the required ethical principles were followed throughout. Discussion and conclusion: Based on the findings of this study from the perspective of caregivers, autistic teenagers need to be cared for and educated in a respectful environment where their privacy is maintained, their individual identities are respected, and they receive comprehensive familial, social, and financial support. These conditions would maintain the dignity of such teenagers and would result in appropriate behavioral outcomes. Therefore, it is suggested that a cultural, professional and institutional background in which all components of the autistic teenager’s dignity are protected and emphasized be provided. (shrink)

The formalist linguists are of the opinion that the literary language is formed by polishing and foregrounding the practiced slang. Many of this literary tricks used in foregrounding are categorized; but there exist some literary tricks that have not been dealt with and are not named or addressed in the available categories.

Background: Euthanasia is a controversial issue in many countries. However, there is little evidence about attitudes of nurses and nursing students toward euthanasia. Research aims: The present study aimed to compare nurses and nursing students' attitudes toward euthanasia. Research design: This is a descriptive cross-sectional study. Participants and research context: Using census sampling, 390 nurses and 125 nursing students were enrolled in this study. Methods: Data were collected using a socio-demographic questionnaire and Euthanasia Attitude Scale that included 20 items that (...) sought to record participants’ level of agreement with euthanasia based on a Likert-type scale. Ethical considerations: Objectives of the study were stated for all samples, and emphasized the confidentiality of their specifics and responses, and informed written consent was obtained from all participants. Findings: The mean score of nurses and nursing students’ attitudes about euthanasia was 3.14 ± 0.26 and 3.22 ± 0.24 out of 5, respectively. The majority of nurses and nursing students had a positive attitude toward euthanasia. There was a significant statistical difference between the attitudes of nurses and nursing students to euthanasia. Discussion: The results indicated that the majority of students and nurses had a positive attitude regarding euthanasia. Conclusion: It was recommended to conduct more studies on euthanasia in Iran.

First-order logic has limited existential import: the universalized conditional ∀x [S → P] implies its corresponding existentialized conjunction ∃x [S & P] in some but not all cases. We prove the Existential-Import Equivalence:∀x [S → P] implies ∃x [S & P] iff ∃x S is logically true.The antecedent S of the universalized conditional alone determines whether the universalized conditional has existential import: implies its corresponding existentialized conjunction.A predicate is a formula having only x free. An existential-import predicate Q is one (...) whose existentialization, ∃x Q, is logically true; otherwise, Q is existential-import-free or simply import-free. Existential-import predicates are also said to be import-carrying.How widespread is existential import? How widespread are import-carrying predicates in themselves or in comparison to import-free predicates? To answer, let L be any first-order language with any interpretation INT in any [sc. nonempty] universe U. A subset S of U is definable in L under INT iff for some predicate Q in L, S is the truth-set of Q under INT. S is import-carrying definable iff S is the truth-set of an import-carrying predicate. S is import-free definable iff S is the truth-set of an import-free predicate.Existential-Importance Theorem: Let L, INT, and U be arbitrary. Every nonempty definable subset of U is both import-carrying definable and import-free definable.Import-carrying predicates are quite abundant, and no less so than import-free predicates. Existential-import implications hold as widely as they fail.A particular conclusion cannot be validly drawn from a universal premise, or from any number of universal premises.—Lewis-Langford, 1932, p. 62.
