ABSTRACT Is it possible to effect singular reference to mathematical objects in the abstractionist framework? I will argue that even if mathematical expressions pass the relevant syntactic and inferential tests to qualify as singular terms, that does not mean that their semantic function is to refer to a particular object. I will defend two arguments leading to this claim: the permutation argument for the referential indeterminacy of mathematical terms, and the argument from the semantic idleness of the terms introduced by (...) abstraction principles.

This paper presents a comparative analysis of three American and three European corporate failures. The first part of the analysis is based on a theoretical framework including six areas of ethical climate; tone at the top; bubble economy and market pressure; fraudulent financial reporting; accountability, control, auditing, and governance; and management compensation. The second and third parts consider the analysis of these cases from fraud perspective and in terms of firm-specific characteristics and environmental context. The research analyses shed light on (...) the fact that, despite major differences between Europe and U.S. in terms of political institutions, laws and regulations as well as managerial practices, there are significant similarities between six groups. The analysis also demonstrates that, the ethical dilemma has been coupled with ineffective boards, inefficient corporate governance and control mechanisms, distorted incentive schemes, accounting irregularities, failure of auditors, dominant CEOs, dysfunctional management behavior and the lack of a sound ethical tone at the top. Significant similarities were also observed in the analysis from the fraud triangle perspective. However, there are several major differences between the six corporate failure cases particularly with regard to ownership structure, coverage in media, and legal, regulatory and governance frameworks. This research study may have several academic and practical contributions, particularly because of multidisciplinary, international features, and comparative analyses used in the paper. (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)

The extension of the principle of relativity to general coordinate systems is based on the hypothesis that an accelerated observer is locally equivalent to a hypothetical inertial observer with the same velocity as the noninertial observer. This hypothesis of locality is expected to be valid for classical particle phenomena as well as for classical wave phenomena but only in the short-wavelength approximation. The generally covariant theory is therefore expected to be in conflict with the quantum theory which is based on (...) wave-particle duality. This is explicitly demonstrated for the frequency of electromagnetic radiation measured by a uniformly rotating observer. The standard Doppler formula is shown to be valid only in the geometric optics approximation. A new definition for the frequency is proposed, and the resulting formula for the frequency measured by the rotating observer is shown to be consistent with expectations based on the classical theory of electrons. A tentative quantum theory is developed on the basis of the generalization of the Bohr frequency condition to include accelerated observers. The description of the causal sequence of events is assumed to be independent of the motion of the observer. Furthermore, the quantum hypothesis is supposed to be valid for all observers. The implications of this theory are critically examined. The new formula for frequency, which is still based on the hypothesis of locality, leads to the observation of negative energy quanta by the rotating observer and is therefore in conflict with the quantum theory.

A gyroscope in orbit about a central rotating mass undergoes relativistic nutational oscillations in addition to the well-known precessional motions. The amplitude of the oscillation is proportional to the angular momentum of the rotating mass and its period is the Fokker period of geodetic precession. The amplitude is maximum for a polar orbit and vanishes if the orbit is equatorial. This nodding effect is due to a small divisor phenomenon involving the Fokker frequency, and its existence implies that the applicability (...) of the post-Newtonian approximation of general relativity is limited in time. The dynamical significance of the new effect for the relative motion of neighboring test masses in the field of a rotating mass as well as for the restricted three-body problem in general relativity is investigated and the possibility of its detection is briefly discussed.

A version of the permutation argument in the philosophy of mathematics leads to the thesis that mathematical terms, contrary to appearances, are not genuine singular terms referring to individual objects; they are purely schematic or variables. By postulating ‘ante-rem structures’, the ante-rem structuralist aims to defuse the permutation argument and retain the referentiality of mathematical terms. This paper presents two semantic problems for the ante- rem view: (1) ante-rem structures are themselves subject to the permutation argument; (2) the ante-rem structuralist (...) fails to explain reference in a way that makes her account different to, and privileged over, that of her eliminativist rivals. Both problems undercut the motivation behind ante-rem structuralism. (shrink)

The realist versions of mathematical structuralism are often characterized by what I call ‘the insubstantiality thesis’, according to which mathematical objects, being positions in structures, have no non-structural properties: they are purely structural objects. The thesis has been criticized for being inconsistent or descriptively inadequate. In this paper, by implementing the resources of a real-definitional account of essence in the context of Fregean abstraction principles, I offer a version of structuralism – essentialist structuralism – which validates a weaker version of (...) the insubstantiality thesis: mathematical objects have no non-structural essential properties. Next, I show how this rendition of structuralism alleviates a Fregean worry against insubstantiality, which is directed at the explanation of the applicability of mathematics from the structuralist perspective.

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

There are two ways of thinking about the natural numbers: as ordinal numbers or as cardinal numbers. It is, moreover, well-known that the cardinal numbers can be defined in terms of the ordinal numbers. Some philosophies of mathematics have taken this as a reason to hold the ordinal numbers as (metaphysically) fundamental. By discussing structuralism and neo-logicism we argue that one can empirically distinguish between accounts that endorse this fundamentality claim and those that do not. In particular, we argue that (...) if the ordinal numbers are metaphysically fundamental then it follows that one cannot acquire cardinal number concepts without appeal to ordinal notions. On the other hand, without this fundamentality thesis that would be possible. This allows for an empirical test to see which account best describes our actual mathematical practices. We then, finally, discuss some empirical data that suggests that we can acquire cardinal number concepts without using ordinal notions. However, there are some important gaps left open by this data that we point to as areas for future empirical research. (shrink)

Cases of grounding failure present a puzzle for fundamental metaphysics. Typically, solutions are thought to lie either in adding ontology such as haecceities or in re‐describing the cases by means of the ideology of metaphysical indeterminacy. The controversial status of haecceities has led some to favour metaphysical indeterminacy as the way to solve the puzzle. We consider two further treatments of grounding failure each of which, we argue, is a more plausible alternative. As such, the initial dichotomy is a false (...) one, and these alternative options deserve consideration before resorting to the heavyweight machinery of metaphysical indeterminacy. -/- . (shrink)

Are there entities which are just distinct, with no discerning property or relation? Although the existence of such utterly indiscernible entities is ensured by mathematical and scientific practice, their legitimacy faces important philosophical challenges. I will discuss the most fundamental objections that have been levelled against utter indiscernibles, argue for the inadequacy of the extant arguments to allay perplexity about them, and put forward a novel defence of these entities against those objections.

According to the realist rendering of mathematical structuralism, mathematical structures are ontologically prior to individual mathematical objects such as numbers and sets. Mathematical objects are merely positions in structures: their nature entirely consists in having the properties arising from the structure to which they belong. In this paper, I offer a bundle-theoretic account of this structuralist conception of mathematical objects: what we normally describe as an individual mathematical object is the mereological bundle of its structural properties. An emerging picture is (...) a version of mereological essentialism: the structural properties of a mathematical object, as a bundle, are the mereological parts of the bundle, which are possessed by it essentially.

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.

According to the neo-Fregean abstractionism, numerical expressions of the form ‘the number of Fs’, introduced by Hume’s Principle, should be read as purportedly referential singular terms. I will explore the prospects of a version of abstractionism in which such expressions have presuppositional content, as in Strawson’s account. I will argue that the thesis that ‘the number of Fs’ semantically presupposes the existence of a number is inconsistent with the required ‘modest’ stipulative character of the truth of Hume’s Principle: since Hume’s (...) Principle is true and provably presupposes that numbers exist, what it presupposes is also true; and so numbers exist. This, however, means that numbers are conjured into existence by a direct stipulation. (shrink)

Reference may be fixed by stipulation through a speech act, just like bets and marriages. An utterance of _Let n refer to an/the F_ is a speech act by means of which, if successful, a speaker institutes a practice of referring, and a hearer coordinates by choosing a referent from the domain of discourse. We articulate a metasemantics for this view. On our view, the interlocutors can select a referent randomly, if necessary, motivated by the incentive to coordinate on the (...) use of a name. Moreover, we argue that reference fixed by a performative speech act is ‘thin’, or ‘undemanding’. Finally, we defend the thesis that co-reference might not determinately obtain despite reference being fixed. Performative reference makes sense of ordinary speakers’ practices, who appear to be very liberal and unimpressed by skepticism toward causally inert or epistemically indiscernible objects. (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)

Millions of children who were born during the first decade after the Islamic revolution in Iran are now reaching the age of marriage and childbearing. Short spacing between marriage and the birth of the first child has the potential to cause an excessive and costly increase in the growth of population in Iran. Research into the motivations for the birth of first child among newly married couples can create a knowledge base that will enable health centres to help these couples (...) make better decisions about the timing of their first pregnancy. Using a consecutive sampling technique and administering Miller’s Childbearing Questionnaire, data were gathered regarding the childbearing motivations and desires of 300 couples who had been referred to the Shiraz Health Center for premarital counselling. The Childbearing Questionnaire, with some minor modifications, was found to be a valid and reliable instrument for measuring the childbearing motivations of newly married couples of Shiraz County, Fars Province, Iran. The utility of these findings for counselling in health centres is discussed. Based on the results, a longitudinal study is being designed that will allow the development of models for predicting the time of first pregnancy after marriage. (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.

According to Øystein Linnebo's account of abstractionism, abstraction principles, received as Fregean criteria of identity, can be used to reduce facts about singular reference to objects such as directions and numbers to facts that do not involve such objects. In this article, first I show how the resources of Linnebo's metasemantics successfully handle Dummett's challenge against the referentiality of the singular terms formed by abstraction principles. Then, I argue that Linnebo's metasemantic commitments do not provide us with tools for dispelling (...) the threat of a version of referential indeterminacy, according to which nothing in our use of a singular term, even when it is guided by an associated criterion of identity, could determine which particular object it refers to. I end by examining the bearing of the indeterminacy challenge to Linnebo's treatment of Frege's Caesar Problem: in the absence of an argument against the indeterminacy of reference, it is unclear how numerical expressions could qualify as genuine singular terms.

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. The attempt is made in this study to find an answer to the questions that why has Mandanipour in his masterpiece, “Shargh-e Banafshe” achieved a superior language that is (...) outstanding among his colleagues of the same era and has become a model in advanced language for the writers to come based on adopting defamiliarization theory in the Leech foregrounding format? Assessing the language of this unique work indicates that in addition to introducing an innovation in the usual styles in contemporary writing and the themes he has allowed assimilation and metaphor and other obsolete styles in his language; and yet has used special literary tricks that have never been tried or tested before. This approach has pat language in story writing to a high position. (shrink)

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.

BackgroundBurn patients are among the most vulnerable groups of patients requiring principled ethical care. Caring for these patients often brings various ethical challenges for the members of the health care teams, especially nurses, which affect the clinical decisions made for these patients. A limited number of studies have addressed the ethical challenges of caring for burn patients for the responsible caregivers, so the present study attempted to identify these challenges. The present study aimed to explore the health professionals' experiences of (...) the ethical challenges during caring for burn patients.MethodsThis was a qualitative study with a descriptive, phenomenological design. 22 health professional practiced in public burn centers in Iran who met the inclusion criteria of the study were selected via purposeful sampling to participate in the study from June to August 2019. Data were collected using semi-structured, in-depth interviews with the individuals as well as field notes. Sampling was continued up to the data saturation. Thereafter, the collected data were analyzed using Colaizzi's method.ResultsThe findings of the study yielded 3 themes, including respect for the patient's privacy, respect for the patient's personal identity, and care challenges, as well as 9 categories.ConclusionThe findings of this study showed that the burn patients’ caregivers face some challenges in the domains of maintaining the patient's privacy, respecting the patient’s personal identity, and making the best clinical decision. Thus, providing the cultural, professional, and organizational requirements of meeting the challenges of caring for burn patients can consequently result in the caregivers’ inner peace and the improved performance.

Games are among cultural manifestations of human communities which have continued to exist since the ancient times and developed during peaceful times; in the Qajar era, during the reign of Nasser-al-Din Shah, because relative peace and prosperity was brought about, the people, especially courtiers, showed great interest in games and spent some of their daily life on it. In this article we have attempted to present some of the angles and dimensions of a number of these games using the itineraries (...) of orientalists and histories and works of that period. In this regard, we have borne in mind time, venue, extensiveness, customs and the reflection of these games in literature and based on evidences demonstrated that Qajar era is one of the most prominent periods in Iranian history and culture regarding the diversity and colorfulness of these games. Skillfulness of game players, large bets, struggles and arguments between opponents, special formalities, etc., are all the criteria for the acceptability and popularity of games in this age, which have been put into consideration.

Background Providing care to children with cancer is one of the most challenging areas of ethical care for nurses. Few studies have addressed nurses’ perception of the barriers to giving ethical care in oncology departments. Thus, it is essential that the ethical challenges in caregiving as perceived by oncology nurses be investigated. Objective The present study was conducted to investigate the ethical challenges as perceived by nurses in pediatric oncology units in the south of Iran. Research design The present study (...) is a qualitative work of research with a conventional content analysis design. Data were collected via individual semi-structured interviews. The collected data were analyzed using the qualitative content analysis method. Participants and research context The participants were 21 nurses from pediatric oncology units in state hospitals who were selected by purposeful sampling. Sampling continued until the data were saturated. The study lasted from April to October 2022. Findings Three main themes, promoting psychological safety in the children, respect for the dignity of the children, and expansion of support for families, and nine subthemes were extracted from the data. Ethical considerations The study’s protocol was approved by the Research Ethics Committee of the University of Medical Sciences and ethical principles were followed throughout the study. Discussion and conclusion From the nurses’ perspective, the major ethical challenges in providing ethical care in pediatric oncology units were reducing tension toward promoting the patients’ psychological safety, showing respect for the identity and dignity of the children with cancer, and expanding support of the patients’ families. By creating the right cultural and professional context and establishing proper protocols, healthcare policymakers and administrators can take effective steps toward eliminating the barriers to providing ethical care.
