In this paper, the notion of the radical of a filter in BL-algebras is defined and several characterizations of the radical of a filter are given. Also we prove that A/F is an MV-algebra if and only if Ds ⊆ F. After that we define the notion of semi maximal filter in BL-algebras and we state and prove some theorems which determine the relationship between this notion and the other types of filters of a BL-algebra. Moreover, we prove that A/F (...) is a semi simple BL-algebra if and only if F is a semi maximal filter of A. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. (shrink)

We define the set of double complemented elements in BL-algebras and state and prove some theorems which determines properties of these sets. We introduce the notion of an almost top element and study the properties of these elements.

Background: Nurses face challenges regarding professional identify. Being unaware of these challenges and not owning positive professional identify leads to a lack of self-confidence. Thus, nurses face problems in interpersonal communication and lose their attachment to their profession. Few studies have engaged with impediments to forming positive professional identity in relation to intensive care nurses. Objective: The purpose of this study is to investigate the impediments to forming positive professional identity in nurses working in intensive care unit. Research design: In (...) this study, the conventional content analysis method was used in order to obtain the impediments to forming positive professional identities in nurses. Data were collected through 15 semi-structured interviews and 2 focus group interviews from March 2015 to June 2016. Purposive sampling was used and participants were recruited until data saturation was reached; they were then analyzed using the conventional content analysis method. Participants and research context: In total, 24 intensive care unit nurses from one hospital in Northern Iran were selected through purposive sampling. Ethical consideration: This study was approved by the Ethics Committee of Shiraz University of Medical Sciences. Findings: Four main themes of professional identity challenges were extracted from the analysis of the data: neglect of professional status of nursing; distrust of nursing knowledge; unprofessional performance; and low professional attraction. Discussion and conclusion: Nurses stated that the neglect of the professional status of nursing and distrust of nursing knowledge have always been a hindrance in forming a positive professional identity. They also mentioned that unprofessional performance and low professional attraction are the other influencing factors in this regard. Thus, detecting these factors can guide nurses and their managers towards creating positive professional identity, and as a result, will improve their job satisfaction, professional advancement, and durability.

Dynamic topological logic is a multi-modal logic that was introduced for reasoning about dynamic topological systems, i.e. structures of the form $\langle{\mathfrak{X}, f}\rangle $, where $\mathfrak{X}$ is a topological space and $f$ is a continuous function on it. The problem of finding a complete and natural axiomatization for this logic in the original tri-modal language has been open for more than one decade. In this paper, we give a natural axiomatization of $\textsf{DTL}$ and prove its strong completeness with respect to (...) the class of all dynamic topological systems. Our proof system is infinitary in the sense that it contains an infinitary derivation rule with countably many premises and one conclusion. It should be remarked that $\textsf{DTL}$ is semantically non-compact, so no finitary proof system for this logic could be strongly complete. Moreover, we provide an infinitary axiomatic system for the logic ${\textsf{DTL}}_{\mathcal{A}}$, i.e. the $\textsf{DTL}$ of Alexandrov spaces, and show that it is strongly complete with respect to the class of all dynamical systems based on Alexandrov spaces.

A major focus of attention in psychology has been on the consequences and determinants of well-being. Religiosity and personality have both been shown to predict mental health and well-being, but the two predictors have not often been investigated together. In 4 studies involving 7 surveys in various social and religious contexts, the relations among well-being, religious orientation, and personality factors were studied. Results showed that Extraversion was the single strongest correlate of higher levels of subjective and psychological well-being. Religiosity had (...) null or weak positive relationships with well-being, and managed to explain variance in some aspects of positive functioning beyond personality factors. The null or week relationship of religiosity with well-being beyond personality was consistent across the HEXACO and the Big Five models of personality structure. It has been suggested that religion is relatively more important for eudaimonic than for hedonic way of living. (shrink)

Soumises à une politique discriminatoire privilégiant le centre, les minorités ethniques en Iran sont depuis longtemps ciblées par la répression étatique, ce qui provoque des mouvements de rébellion. Le soulèvement de 2019 a révélé une nouvelle facette de la violence de l’État contre les minorités dans des périphéries du pays où le développement économique a été délibérément freiné par le régime. Ces affrontements témoignent d’une crise de citoyenneté dans le pays qui mérite une attention particulière.

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)

As studies continue to accumulate on leader humility, it has become clear that humility in a leader is largely beneficial to his or her followers. While the majority of the empirical research on this topic has demonstrated the positive effects of leader humility, this study challenges that consensus by arguing that a leader’s humble behavior can have contradictory outcomes in followers’ voice behavior. Drawing on attachment theory, we develop a model which takes into account the ways in which leader humility (...) influences the seemingly contradictory voice behavior of followers, i.e., inducing challenging voice, and defensive voice depending on the followers’ sense of security as reflected by feeling trusted and self-efficacy for voice. The results of this empirical study confirm that leader humility influences followers’ voice in a contradictory way through their sense of security. (shrink)

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.

Application of technologies has an important role in agricultural development. Identifying and assessing the impacts of agricultural technologies is necessary. This study aimed at assessing the impacts of laser levelling economically, socially, environmentally, and technically in the viewpoint of the agricultural experts and identifying factors determining their perception of the impacts. The study samples (151 experts) were selected using multi-stage random sampling in Fars Province, Iran. The results revealed that experts considered uniform distribution of water, using conservation tillage, facilitating agricultural (...) activities, decreased water consumption and decrease of water wasting as the most important technical impacts of laser levelling technology. The most environmentally important impacts were the decrease of soil erosion and retention of crop residues. Experts stated the most significant social impacts as improvement in villages living conditions and sense of belonging to rural areas. Besides, an increase of income and reduction of inputs costs were among the economic impacts of laser levelling technology. According to the results, attitude towards water and soil resources conservation and environmental beliefs had the highest direct effect on individual perception toward impacts. Practical recommendations have been presented based on the results of the study. (shrink)

BackgroundCognitive impairments are prevalent in patients with unipolar and bipolar depressive disorder. Considering the fact assessing cognitive functions is increasingly feasible for clinicians and researchers, targeting these problems in treatment and using them at baseline as predictors of response to treatment can be very informative.MethodIn a naturalistic, retrospective study, data from 120 patients with UDD and BDD were analyzed. Patients received 20 sessions of bilateral rTMS and were assessed regarding their depressive symptoms, sustained attention, working memory, and executive functions, using (...) the Beck Depression Inventory and Neuropsychological Test Automated Battery Cambridge, at baseline and after the end of rTMS treatment course. Generalized estimating equations and logistic regression were used as the main statistical methods to test the hypotheses.ResultsFifty-three percentage of all patients responded to treatment. In particular, 53.1% of UDD patients and 46.9% of BDD patients responded to treatment. Bilateral rTMS improved all cognitive functions except for visual memory and resulted in more modulations in the working memory of UDD compared to BDD patients. More improvements in working memory were observed in responded patients and visual memory, age, and sex were determined as treatment response predictors. Working memory, visual memory, and age were identified as treatment response predictors in BDD and UDD patients, respectively.ConclusionBilateral rTMS improved cold cognition and depressive symptoms in UDD and BDD patients, possibly by altering cognitive control mechanisms, and processing negative emotional bias.
