The Semantic-Pragmatic Analysis of Persian Modal Verbs Based on Papafragou's Model This paper aims at analyzing the semantics and pragmatics of Persian modal verbs based on Papafragou's relevance-theoretic model. Persian modals are defined in terms of logical relations and propositional domains. According to the findings of the research, two of the three modals, namely, šodan and tavân express the logical relation of compatibility with respect to different propositional domains: the three forms mišavad, mišod and mišode are unspecified with respect to (...) their propositional domains and take them directly from the context, whereas betavân and bešavad accept the desirability domain. Mitavân also expresses compatibility in relation to the propositions in the factual domain. However, bˇyad is the only modal that encodes the logical relation of entailment and is unspecified with respect to the type of propositional domain it accepts. (shrink)

Background and ObjectivesFocal cortical dysplasia is a type of malformations of cortical development and one of the leading causes of drug-resistant epilepsy. Postoperative results improve the diagnosis of lesions on structural MRIs. Advances in quantitative algorithms have increased the identification of FCD lesions. However, due to significant differences in size, shape, and location of the lesion in different patients and a big deal of time for the objective diagnosis of lesion as well as the dependence of individual interpretation, sensitive approaches (...) are required to address the challenge of lesion diagnosis. In this research, a FCD computer-aided diagnostic system to improve existing methods is presented.MethodsMagnetic resonance imaging data were collected from 58 participants. Morphological and intensity-based features were calculated for each cortical surface and inserted into an artificial neural network. Statistical examinations evaluated classifier efficiency.ResultsNeural network evaluation metrics—sensitivity, specificity, and accuracy—were 96.7, 100, and 98.6%, respectively. Furthermore, the accuracy of the classifier for the detection of the lobe and hemisphere of the brain, where the FCD lesion is located, was 84.2 and 77.3%, respectively.ConclusionAnalyzing surface-based features by automated machine learning can give a quantitative and objective diagnosis of FCD lesions in presurgical assessment and improve postsurgical outcomes.

This study examined the opening and closing sequences of requestive e–mails written by 66 native English speaking students and 34 Iranian students sent to a faculty member in an American university. Three hundred requestive e–mails from NES students and NNES students sent to a professor were collected over six semesters and were analyzed for the cultural and social variation that exists in e–mail communication. Students’ choices of opening and closing strategies were examined with respect to different interpersonal styles of politeness. (...) Quantitative and qualitative findings revealed that solidarity and deference towards the professor were expressed differently in the e–mails of NES students and NNES students. (shrink)

Conversational implicatures (CIMs) are implied by the speaker in context rather than being linguistically encoded, and learners’ inability to infer the intended meaning, if not remedied through instruction (or mediation), leads to communication breakdowns. Given this premise, the current study aimed to examine effects of classroom praxis-based instruction adjusted to EFL learners’ Zone of Proximal Development (ZPD) on their comprehension of CIMs. Participants were 36 Iranian high school students in 2 classrooms, assigned to experimental and comparison groups. A 20-item CIM (...) test was administered at pretest and posttest times to collect the data. Microgenetic trajectories were also traced through audio-recorded role-plays and social interactions within the ZPD setting. ZPD-adjusted mediational instruction on CIMs was given based on a multi-level regulatory scale and a view of microgenetic development along an other-to self-regulated functioning continuum. In the non-ZPD setting, mainstream teacher-fronted instruction was employed. ANCOVA results revealed differential instructional effects in favor of the praxis-based mediational setting. Microgenetic learning episodes also portrayed how collectively-mediated, ZPD-activated learning led to L2 learners’ progressively improved comprehension of CIMs. The findings suggest that comprehension (and perhaps production) of L2 CIMs can be improved through praxis-oriented co-construction of pragmatic knowledge through collaborative engagement with communicative activity.

Purpose: Despite various comparative studies in the field of cultural heritage protection in the world, there is still a significant lack of comparative research on policies related to the legal system of countries' governance. The purpose of this study is to address the comparative policies in Iran and Italy, with a particular focus on the results of the executive experiences of two different types of policies in the cities of Oroumieh (North-West of Iran) and Turin (in North-West of Italy). Design/methodology/approach: (...) Utilising the comparative, analytical, bibliographic and descriptive historical research methodology, which is based on the study of the local, national and international comprehensive review of regulations and policy-making of cultural heritage preservation policies in Iran and Italy. In this research, the related documents in three languages (Persian, Italian and English) have been examined to compare profoundly and comprehensively the policies and regulations adopted in these two countries to be able to analyze the national and transnational regulations and local policies in the cultural heritage sector. Findings: In addition to many cultural similarities and numerous commonalities, especially in the multiplicity of urban cultural heritage in historical centers, the results suggest that the legislation structure in Iran is much more centralized than in Italy. Also, the findings suggest that Italy focuses on aligning its previously centralized national legislative system in line with contemporary European heritage and preservation policies. Originality/value: The paper outlines how to use historical and cultural similarities through comparative study to benefit the experiences of two historical countries in urban heritage conservation and policy-making part despite their differences.

Technostress is evolving as an imperative area of academic research amid the “new normal” settings of working remotely. Research has investigated the relationships between technostress and job outcomes and proposed individual- and organizational-level approaches to manage it. However, insights into the influence of dynamic personality differences on this relationship are limited. This study ties the concept of self-efficacy to the transactional model of stress and coping, and investigates to what extent computer and social self-efficacy moderate the relationships between technostress creators (...) and frontline employee’s job performance. Findings shift the focus from the negative aspects of technostress and outcomes to both positive and negative aspects. This study’s contributions and implications for theory and practice are discussed. (shrink)

This article investigates the political role of social theories in contemporary Iran. It focuses, specifically, on how the 1979 Revolution marks a passage in Iranian political and social thought from political radicalism informed by Marxism to reformist liberalism inspired by local readings of Weber, Habermas, and Giddens. By investigating the writings of public intellectuals and political activists involved in Iran’s reform movement, the article traces their transformation from leftist revolutionary radicals to liberal proponents of free market, democracy, and religious pluralism. (...) It will be argued that an inadequate understanding of economic issues underlies the political failings of this movement. (shrink)

This article investigates the construction of urban/rural binary distinctions in 18th - and 19th-century social scientific literature, and in particular in the writings of the statistical societies in England. The 18th-century writers were primarily concerned with the spread of luxury, vice and effeminacy among the upper social strata in large cities. Later on, statisticians began to focus on moral hazards among the urban working poor. These writings are significant in several respects: they contributed to the spatial mapping of moral character, (...) played a role in the development of quantitative social scientific techniques, and foreshadowed later sociological debates over the nature and consequences of social evolution from simpler to more complex societies.

Background Healthy aging is one of the essential aspects of a health promotion program in the elderly. Aim Exploring ethical challenges in healthy elderly care from the perspective of nurses, older adults, and families in the Iranian context. Research Design This qualitative study was conducted using a content analysis approach in 4 health centers in northeastern Iran from 2017 to 2019. Semi-structured interviews, observation, review of elderly files, and focus groups were used to collect data. Ethical considerations The ethics committee (...) of the university approved this study in Iran. This study adhered to the principles of the Helsinki Declaration. Ethical principles autonomy, confidentiality, and anonymity were considered for the participants. Participants were informed about the purpose of the study and submitted written informed consent regarding their participation. Findings The central theme was: An unfair approach to caring for healthy older adults. The three categories were as follows: Forgotten human care, disrespect, and lack of a meaningful and trustworthy relationship. The 14 subcategories highlighted the ethical challenges of healthy aging care in health centers. Discussion The findings showed that due to nurses’ unfamiliarity with the concept of healthy aging, older adults are discriminated against in care centers. Creating a standard care program for healthy older adults ensures that ethical principles are followed for these clients. Conclusion Various individual and organizational factors lead to an unfair approach to caring for healthy elderly in health centers. The following factors can help improve the care of healthy aging and reduce ethical challenges in this area: Introducing nurses to the concept of healthy old age and its dimensions, creating a community-based approach in health centers, prioritizing health issues over health issues, Involvement of families and older adults in needs assessment-goal setting-implementation and evaluation of health services, and design of home visit programs to provide services to healthy elderly.

In this paper, considering \(L\)-algebras, which include a significant number of other algebraic structures, we present a definition of modules on \(L\)-algebras (\(L\)-modules). Then we provide some examples and obtain some results on \(L\)-modules. Also, we present definitions of prime ideals of \(L\)-algebras and \(L\)-submodules (prime \(L\)-submodules) of \(L\)-modules, and investigate the relationship between them. Finally, by proving a number of theorems, we provide some conditions for having prime \(L\)-submodules.

The present study investigates variability among raters from different linguistic backgrounds, who evaluated the pragmatic performance of English language learners with varying native languages (L1s) by using both self- and peer-assessments. To this end, written discourse completion task (WDCT) samples of requesting speech acts from 10 participants were collected. Thereafter, the participants were asked to assess their peers’ WDCTs before assessing their own samples using the same rating scale. The raters were further asked to provide an explanation for their rating (...) decisions. Findings indicate that there may indeed be a link between a rater’s language background and their scoring patterns, although the results regarding peer- and self-assessment are mixed. There are both similarities and differences in the participants’ use of pragmatic norms and social rules in evaluating appropriateness. (shrink)

Accumulation of neurotransmitters in the lumen of synaptic vesicles (SVs) relies on the activity of the vacuolar‐type H+‐ATPase. This pump drives protons into the lumen, generating a proton electrochemical gradient (ΔμH+) across the membrane. Recent work has demonstrated that the balance between the chemical (ΔpH) and electrical (ΔΨ) components of ΔμH+ is regulated differently by some distinct vesicle types. As different neurotransmitter transporters use ΔpH and ΔΨ with different relative efficiencies, regulation of this gradient balance has the potential to influence (...) neurotransmitter uptake. Nevertheless, the underlying mechanisms responsible for this regulation remain poorly understood. In this review, we provide an overview of current neurotransmitter uptake models, with a particular emphasis on the distinct roles of the electrical and chemical gradients and current hypotheses for regulatory mechanisms. -/- .

Background To practice nursing ethics, students must first understand the ethical concepts and principles of their profession, but despite this knowledge, students face challenges in implementing ethical principles in clinical settings. The educational performance of nurse educators is critical in resolving these challenges. This study focused on the lived experiences of nurse educators. Objective To address the main concern of educators when teaching ethics to undergraduate nursing students and how they deal with it. Research Design We conducted this qualitative content (...) analysis in Iran in 2020. We used individual semi-structured interviews to collect, record, and transcribe data, as well as Graneheim and Lundman method to analyze them. Participants and research context: We used purposive sampling to select 11 nurse educators who either were currently in the position of ethics educators or had taught ethics from Iranian universities of medical sciences. Ethical considerations The present study received the code of ethics No. IR.MODARES.REC.1399.036. Participants were aware of the study’s purpose and signed a consent form to participate in the study. We considered data confidentiality and the voluntary principle in data collection. Findings Nurse educators’ main concern was how to sensitize students to ethical principles in clinical settings, so they tried to involve students in the teaching process, to repeat and practice ethical principles and concepts, simplify and simulate ethical principles and concepts, and provide opportunities for students to gain clinical experiences. Discussion To sensitize students to ethical nursing care, nurse educators try to institutionalize ethical principles using different teaching methods, including students' involvement in teaching, experiential learning through simulated situations, practice, repetition, and provision of opportunities for practice and experience. Conclusion Improving students’ cognitive ability and objectifying moral concepts and principles for students will institutionalize moral values in them that are fundamental for their moral sensitization.

BackgroundIn order to achieve the goals of the healthcare system, nursing managers are required to comply with ethical principles in decision-making. In complex and challenging healthcare settings, it is shown that the managers’ mere awareness of ethics does not suffice and managers need to be sensitive toward making ethical decisions.AimTo explore nursing managers and their sensitivity toward ethical decision-making by analyzing their related experiences.MethodThe current study has been conducted in Iran in 2017 through a qualitative content analysis approach. Nineteen nurse (...) managers were selected purposefully from different hospitals in Tehran. Data were collected using semi-structured, in-depth, face-to-face interviews, and after transcription, they were analyzed according to the Graneheim and Lundman method.Ethical considerationsThe research was approved by the ethics committee of Tarbiat Modares University, Tehran, Iran. Participants were informed about the purpose of the study and submitted written informed consents regarding their participation. The principle of autonomy, confidentiality, and anonymity was taken into account in data collection.ResultsFifteen subcategories, three categories (assertiveness, commitment, and insight), and one theme of excellent decision-making were the results of data analysis.DiscussionFindings showed that nursing managers’ sensitivity to ethical decision-making allows them to make the best decision by insight, commitment, and assertiveness. Making a morally excellent decision ensures that ethical principles are followed in the healthcare system.ConclusionConsidering that most managers are committed to making ethical decisions, it is required to develop the scope of their insights even further using a professional management and ethical principles training program. Also, by addressing some of the ethical barriers at personal and organizational levels, the assertiveness in managers can be improved, which in turn can facilitate their ethical decision-making.

This article reports the results of a qualitative study that used a deep interview method. The aim was to gather lived experiences of clinical nurses employed at government-funded medical centres regarding the non-materialistic and spiritual aspects of the profession that have had an important impact on their job satisfaction. On analysing the participants' concepts of spiritual satisfaction, the following themes were extracted: spiritually pleasant feelings, patients as celestial gifts, spiritual commitment, spiritual penchant, spiritual rewards, and spiritual dilemmas. Content analysis of (...) the data indicated that nurses who viewed these dimensions of job satisfaction as a significant factor considered nursing as an opportunity to worship God while providing care for patients, and regarded their aim as achieving patients' contentment by providing nursing care compatible with scientific care methods.

The problem of finding optimal sampling schemes has been resolved in two models. The novelty of this study lies in its cost efficiency, specifically, for the applied problems with expensive sampling process. In discussed models, we show that some observations counteract other ones in prediction mechanism. The autocovariance function of underlying process causes mentioned result. Our interesting result is that, although removing neutralizing observations convert sampling scheme to nonredundant case, it causes to worse prediction. A simulation study confirms this matter, (...) too. (shrink)

The aim of this phenomenological research study carried out in Iran was to capture the meaning of patients' rights from the lived experiences of patients and their companions. To achieve this, 12 semistructured interviews were conducted during 2005 in a teaching hospital in Tehran with patients and/or their companions. In addition, extensive field notes were compiled during the interviews. The data were analyzed using Benner's thematic analysis. The themes captured were classified into three main categories, with certain themes identified within (...) each category. The categories were: (1) the concept of patients' rights; (2) barriers to patients' rights; and (3) facilitators of patients' rights. The distinctive themes within each of the categories were identified as: (1a) receiving real care, (1b) focus on the patient, and (1c) equality and accessibility; (2a) dissatisfaction with caregivers, and (2b) specific work environment limitations; (3a) the patient's companion, (3b) a responsible system, and (3c) the public's awareness of rights. Although certain themes identified closely resemble those identified in international patients' bills of rights, the current study focused on themes that are particularly relevant to the Iranian sociocultural context.

Compare with other professions, teachers are reported to have a higher risk of poor mental health. This study examined the relationships between emotional intelligence, perceived organizational justice, and mental health among Chinese high school teachers. Three hundred and eighty-one high school teachers, with their age range between 21 and 50 years, were administered the Emotional Intelligence Scale, Perceived Organizational Justice Scale, and Mental Health Scale. The result found that emotional intelligence and perceived organizational justice directly influence the mental health of (...) high school teachers. In addition, perceived organizational justice mediated the association between emotional intelligence and mental health. Moreover, the present study analyzes the different role of subtypes of perceived organizational justice on the relationships between emotional intelligence and mental health, and the results showed that the mediating effects of perceived distributive justice and interactive justice on emotional intelligence and mental health are not significant, only the perceived procedural justice mediated the relationships between emotional intelligence and teachers’ mental health. The results are discussed in a conceptual context. (shrink)

It is imperative to understand the factors that influence clinical competency. Consequently, it is essential to study those that have an impact on the process of attaining clinical competency. A grounded theory approach was adopted for this study. Professional competency empowers nurses and enables them to fulfill their duties effectively. Internal and external factors were identified as affecting clinical competency. A total of 36 clinical nurses, nurse educators, hospital managers and members of the Nursing Council in Tehran participated in this (...) research. Data were obtained by semistructured interviews. Personal factors and useful work experience were considered to be significant, based on knowledge and skills, ethical conduct, professional commitment, self-respect and respect for others, as well as from effective relationships, interest, responsibility and accountability. Effective management, education systems and technology were named as influential environmental factors. Personal and environmental factors affect clinical competency. Ethical persons are responsible and committed to their work, acquiring relevant work experience. A suitable work environment that is structured and ordered also encourages an ethical approach by nurses. (shrink)

Recently, megastable systems have grabbed many researchers’ interests in the area of nonlinear dynamics and chaotic systems. In this paper, the oscillatory terms’ coefficients of the simplest megastable oscillator are forced to blink in time. The forced system can generate an infinitive number of hidden attractors without changing parameters. The behavior of these hidden attractors can be chaotic, tori, and limit cycle. The attractors’ topology of the system seems unique and looks like picture frames. Besides, the existence of different coexisting (...) attractors with different kinds of behaviors reflects the system's high sensitivity. Using the sample entropy algorithm, the system’s complexity for different initial values is assessed. In addition, the circuit of the introduced forced system is designed, and the possibility of implicating the system with analog elements is investigated. (shrink)

In this paper, by considering the notion of MV-module, which is the structure that naturally correspond to lu-modules over lu-rings, we study injective MV-modules and we investigate some conditions for constructing injective MV-modules. Then we define the notions of essential A-homomorphisms and essential extension of A-homomorphisms, where A is a product MV-algebra, and we get some of there properties. Finally, we prove that a maximal essential extension of any A-ideal of an injective MV-module is an injective A-module, too.

This paper explores the epistemological affordances of Islamic ethics as alternative knowledge within intercultural education. Despite the calls for epistemological plurality in intercultural education that centre epistemologies of the South, educators may find it hard to reaffirm their situated knowledges and practices because they may have been overwhelmed by the wide endorsements of the mainstream literature. Drawing on in-depth interviews with 25 EFL teachers, this study aims to (a) unpack educators’ perspectives around the adoption of alternative knowledges anchored in local (...) epistemologies and sensibilities, (b) foreground educators’ epistemic positioning around alternative knowledges and how they are perceived as sites for cognitive and pedagogical renewal to account for local particularities and conditions and (c) examine inter-epistemic tensions within educators’ reasoning in terms of how they navigate (in)congruencies between the mainstream and Islamic philosophy at the conceptual, pedagogical and practical levels. Findings reveal that educators acknowledge the legitimacy of Islamic ethics and their epistemological/pedagogical significance in intercultural education. However, some factors may problematize educators’ attempts at making use of Islamic ethics including the additional burden of reflecting alternative knowledges while attending to contextual factors (class size, the course’s orientation, exams, time constraints, etc.) and the lack of sufficient training in intercultural education.

The main goal of this study was to identify factors motivating pragmatic transfer in advanced learners of English. Based on a cross-cultural comparison of requesting behavior between Koreans and Americans, this study determined the impact of individual subjective motives on pragmatic language choice. Two different groups of subjects participated in this study: 30 Korean participants and 30 American college students. Data were collected by using a Discourse Completion Task. Korean participants provided the data for Korean and English versions of DCT. (...) Semi-structured interviews were also conducted with 13 Korean ESL learners who showed the most and least amount of pragmatic transfer. Findings showed evidence of pragmatic transfer in the request responses given by Korean ESL learners in their requestive strategies, level of directness, and perspectives of head acts. The interview data revealed that Korean students were conscious of differing rules for making requests. Learners’ judgment of L2 pragmatic norms, perception of their own language, and their attitudes of the target language influence language use. Furthermore, findings showed that purpose of learning English, different types of motivation, and the length of intended residence contribute to the extent of pragmatic transfer. (shrink)

BackgroundMedical education is currently more considerate about the human dimension. The present qualitative study aimed to explain the experiences of clinical professors with regard to humanism in clinical education in Iran.MethodsThis mixed methods study had two phases, a quanitative phase of scientometrics and a qualitative phase of a content analysis. In the scientometrics phase, Ravar PreMap and VOSviewer software programs were utilized for plotting the conceptual networks. The networks were analyzed at the micro-level based on centrality indices. The conceptual network (...) was plotted and the prominent topics in clinical education were identified using co-word analysis. In the second qualitative phase on the topic, based on the scientometrics phase, semi-structured interviews were conducted with clinical professors. The interviews were transcribed verbatim and analyzed.ResultsOn the basis of the analysis of titles, abstracts, and keywords of the retrieved articles on clinical education from ISI Web of Science, Scopus, and PubMed, 1412 keywords were extracted. After the refining process, 356 keywords with 6741 relations remained. Upon plotting the conceptual network, 19 conceptual clusters related to clinical education were obtained. Then, micro-level network analysis indicated that the keyword humanism with the frequency of 137 had the highest rate, closeness, and betweenness. Moreover, from the interview data analysis, two themes of “intertwined nature of the human spirit in clinical education” and “humanistic behavior of professors in clinical education” were extracted.ConclusionAs a part of the educational culture, humanistic values must be intertwined with the medical education curriculum. In this regard, humanism and clinical reasoning are the two major clusters of clinical teaching; moreover, altruism and adherence to humanistic values, and scientific qualification are other main pillars that should be considered as the criteria for the selection of clinical professors and medical students.

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)

Background Moral distress is a common challenge among professional nurses when caring for their patients, especially when they need to make rapid decisions. Therefore, leaving moral distress unconsidered may jeopardize patient quality of care, safety, and satisfaction. Aim To estimate moral distress among nurses. Methods This systematic review and meta-analysis conducted systematic search in Scopus, PubMed, ProQuest, ISI Web of Knowledge, and PsycInfo up to end of February 2022. Methodological quality of included studies was assessed using the Newcastle Ottawa checklist. (...) Data from included studies were pooled by meta-analysis with random effect model in STATA software version 14. The selected key measure was mean score of moral distress total score with its’ 95% Confidence Interval was reported. Subgroup analyses and meta-regressions were conducted to identify possible sources of heterogeneity and potentially influencing variables on moral distress. Funnel plots and Begg’s Tests were used to assess publication bias. The Jackknife method was used for sensitivity analysis. Ethical consideration The protocol of this project was registered in the PROSPERO database under decree code of CRD42021267773. Results Eighty-six manuscripts with 19,537 participants from 21 countries were included. The pooled estimated mean score of moral distress was 2.55 on a 0–10 scale [95% Confidence Interval: 2.27–2.84, I2: 98.4%, Tau2:0.94]. Publication bias and small study effect was ruled out. Moral distress significantly decreased in the COVID-19 pandemic versus before. Nurses working in developing countries experienced higher level of moral distress compared to their counterparts in developed countries. Nurses' workplace (e.g., hospital ward) was not linked to severity of moral disturbance. Conclusion The results of the study showed a low level of pooled estimated score for moral distress. Although the score of moral distress was not high, nurses working in developing countries reported higher levels of moral distress than those working in developed countries. Therefore, it is necessary that future studies focus on creating a supportive environment in hospitals and medical centers for nurses to reduce moral distress and improve healthcare. (shrink)

Benchmarking is the major reason for the widespread use of DEA models for efficiency analysis. Determining the closest targets for DMUs, DEA models play a key role in benchmarking their best performance. In fact, these models help develop certain performance enhancement plans that need fewer attempts made by DMUs. Therefore, this study proposes a novel method based on the network DEA to determine the most appropriate target for every stage in addition to benchmarking the DMUs. The proposed model differs from (...) those proposed by other studies in the fact that all DEA models of benchmarking consider input and output values to be linear. However, in real-world problems, many DMU inputs and outputs have nonlinear values, something which was taken into account in the modeling process in this study. The proposed model was employed to benchmark cement factories listed on the Tehran Stock Exchange. (shrink)
