One of the mathematical programming techniques is data envelopment analysis, which is used for evaluating the efficiency of a set of similar decision-making units. Fixed resource allocation and target setting with the help of DEA is a subject that has gained much attention from researchers. A new model was proposed by determining a common set of weights. All DMUs were involved with the aim of achieving higher efficiency in every DMU after the procedure. The minimum resources and targets allocated to (...) each DMU were commensurate to the efficiency of that DMU and the share of DMU in the input resources and the output productions. To examine the proposed method, other methods in the DEA literature were examined as well, and then, the efficiency of the method was demonstrated through a numerical example. (shrink)

AimsThis study aimed to investigate barriers in the observation of professional ethics during clinical care from a nursing viewpoint. Also, it examined the association between these barriers and nurse demographic variables.MethodsA descriptive-analytic design was carried out on 207 nurses working in selected hospitals within an urban area of Iran in 2019. Data were collected using a standard questionnaire containing 33 questions that measured barriers to observation of professional ethics. The questionnaire measures three domains of management, environment and individual care.ResultsIn the (...) management dimension, the most important barrier preventing observation of professional ethics was the shortage of personnel. For the environmental dimension, biological changes due to working on the nightshift, and for the individual care dimension, a lack of time were the most important barriers preventing observation of clinical ethics. Findings additionally highlighted a significantly inverse association between barriers to observing professional ethics and the male gender, participating in the ethics workshop and high work-level experiences.ConclusionsIt is suggested that nursing managers in hospitals correct and remove obstacles with careful planning and emphasis on principles and standards of care including environmental and managerial factors and training professional ethics to nurses.

This paper investigates the structure of networked publics and their sharing practices in Persian Twitter during a period surrounding Iran’s 2017 presidential election. Building on networked gatekeeping and framing theories, we used a mixed methodological approach to analyze a dataset of 2,596,284 Persian tweets. Results revealed that Twitter provided a space for Iranians to discuss public topics. However, this space is not necessarily used by voiceless and marginalized groups; and the uses are not limited to discussing controversial issues. The growing (...) body of conservative crowdsourced elites emerged to defend the regime’s ideology. Moreover, the dominant networked frames were shaped around normal and routine subjects in an election time. Thus, Twitter was not a platform for only seeking liberal demands. It was to some extent used to serve the regime’s political interests. Furthermore, while many ordinary users rose to prominence, mainstream media continued to act as powerful players. This study contributes to the existing literature into networked practices, digital democracy, and citizen journalism; particularly in restrictive contexts. (shrink)

Previous research with speech and non-speech stimuli suggested that in audiovisual perception, visual information starting prior to the onset of corresponding sound can provide visual cues, and form a prediction about the upcoming auditory sound. This prediction leads to audiovisual interaction. Auditory and visual perception interact and induce suppression and speeding up of the early auditory event-related potentials such as N1 and P2. To investigate AV interaction, previous research examined N1 and P2 amplitudes and latencies in response to audio only, (...) video only, audiovisual, and control stimuli, and compared AV with auditory perception based on four AV interaction models. The current study addresses how different models of AV interaction express N1 and P2 suppression in music perception. Furthermore, the current study took one step further and examined whether previous musical experience, which can potentially lead to higher N1 and P2 amplitudes in auditory perception, influenced AV interaction in different models. Musicians and non-musicians were presented the recordings of a keyboard /C4/ key being played, as well as CO stimuli. Results showed that AV interaction models differ in their expression of N1 and P2 amplitude and latency suppression. The calculation of model and has consequences for the resulting N1 and P2 difference waves. Furthermore, while musicians, compared to non-musicians, showed higher N1 amplitude in auditory perception, suppression of amplitudes and latencies for N1 and P2 was similar for the two groups across the AV models. Collectively, these results suggest that when visual cues from finger and hand movements predict the upcoming sound in AV music perception, suppression of early ERPs is similar for musicians and non-musicians. Notably, the calculation differences across models do not lead to the same pattern of results for N1 and P2, demonstrating that the four models are not interchangeable and are not directly comparable.

Background: Dignified care is one of the main objectives of holistic care. Furthermore, paying attention to dignity as one of the fundamental rights of patients is extremely important. However, in many cases, the dignity of hospitalized patients is not considered. Dignity is an abstract concept, and comprehensive studies of the dignity of Iranian patients hospitalized in general hospital settings are limited. Objective: The aim of this study was to explore the concept of dignity from the perspective of patients hospitalized in (...) general hospital settings in Iran. Research design: This study takes a qualitative approach. Data were gathered using individual, semi-structured interviews. Qualitative content analysis was the method used to analyse and interpret the data. The criteria suggested by Guba and Lincoln were used ensure the trustworthiness of the study. Participants and research context: A total of 14 hospitalized patients in general hospital settings in Shiraz participated in this study. Ethical considerations: The Research Ethics Committee of the Shiraz University of Medical Sciences approved the protocol of the study and the ethical principles were followed throughout. Findings: The findings of this study revealed four main themes – ‘respectful atmosphere’, ‘patient privacy’, ‘preservation of authority’ and ‘receiving attention’ – and 10 categories. Discussion: Patients need to be hospitalized in a respectable environment in which their privacy is preserved and paid attention, providing them with sufficient authority in terms of medical decisions and their life-related issues. The dignity of hospitalized patients will be preserved under these conditions. Conclusion: Patients hospitalized in general hospital settings need to retain their dignity. This can contribute to the optimal therapeutic outcomes for them. Therefore, it is suggested that a cultural, professional and institutional background, in which all components of the patient’s dignity are protected and emphasized, should be provided. (shrink)

Some researchers, even professors in universities, sometimes do unethical actions unintentionally due to lack of a mentor in their academic life. In this opinion piece, we aim to show that journals and publishers can play the role of a mentor for authors of scientific articles, especially young M.Sc. and Ph.D. students, to teach them the ethics in research and publishing. In this way, both journals and researchers will benefit from such a plan.

This survey was conducted in 2017 to investigate factors influencing social risk perception of biotechnologists and plant breeders in training toward GM food based on a conceptual model. A random sample of 210 biotechnologists and plant breeders in training was studied. Confirmatory factor analysis and the reliability tests have been used to verify the uni-dimensionality of the measurement scale, SEM also was carried out to determine the most parsimonious models with the best fit for social risk perception of GM foods (...) and path analysis was conducted to understand the exogenous variables introduced in the research model. The findings revealed that the engineers in training had moderate social risk perception regarding GM foods. Moreover, the results of structural equation modeling showed the capability of the model in predicting the social risk perceptions of engineers in training. The psychological attributes of risks, social benefit perception, attitude toward using technology, level of religiosity, and moral and ethical beliefs emerged as the most powerful predictors of the social risk perception. The social benefit perception and attitude toward using technology also mediated the effects of psychological attributes of risks, level of religiosity, and moral and ethical beliefs. The social benefit perception also had an indirect influence on the engineers in training’s social risk perception of GM foods. Finally, we recommend the application of the model developed by this study for better understanding of social risk perception of stakeholders to have a more informed view of the development and promotion of GM foods.

A person who arrives at correct solutions via false premises is right and wrong simultaneously. Similarly, a person who generates “logical intuitions” through superficial heuristics can likewise be right and wrong at the same time. However, heuristics aren't guaranteed to deliver the logical solution, so the claim that system 1 can routinely produce the alleged system 2 response is unfounded.

Collaborative learning with cases characteristically involves discussing and developing shared explanations. We investigated the argumentation scheme which learners use in constructing shared explanations over evidence. We observed medical students attempting to explain how a judge had arrived at his verdict in a case of medical negligence. The students were learning within a virtual learning environment and their communication was computer mediated. We identify the dialogue type that these learners construct and show that their argumentation conforms with an abductive form of (...) argumentation scheme (‘inference to the best explanation’). We also assessed the students’ learning and propose that it is related to particular features of this argumentation scheme. (shrink)

The outbreak of the COVID-19 pandemic has resulted in many emotional consequences for teachers, including feelings of isolation, loneliness, and hopelessness. However, evidence on the prevalence of hopelessness and the associated factors in teachers during the pandemic is limited. The purpose of this research was to examine the prevalence of hopelessness in public school teachers and identify risk factors associated with it. A sample of 168 teachers aged 25–49 years participated in the study by completing the Socio-Demographic Questionnaire, the Beck (...) Hopelessness Scale, and the Multi-Dimensional Scale of Perceived Social Support. The results revealed a moderate level of experienced hopelessness in teachers. Hopelessness prevalence was also significantly different across teacher gender, age groups, socioeconomic status, educational level, professional experience, and perceived social support. The results of a logistic regression analysis confirmed the effects of these demographic and occupational attributes on hopelessness by explaining ~71% of the variance in hopelessness feelings. Higher odds ratios were associated with age, socioeconomic status, and perceived social support, signifying the prominence of these factors in predicting hopelessness. The study contributes to identifying and screening teachers at risk of hopelessness in public schools and recommends promoting collegial/superior support as well as a positive school climate as the protective factors against hopelessness.

ABSTRACT As a culture-specific phenomenon, academic dishonesty remains an under-researched domain. The purpose of this study was to voice teachers’ perceptions of: the influential factors contributing to AD, the consequences of AD for the quality of teacher–student relationships, and the specific strategies for regulating TSR. Using a qualitative phenomenological design, we attempted to present a detailed description of teachers’ lived experiences regarding the above aims. The participants were English language and Mathematics teachers with different personal and professional characteristics working in (...) public high schools of Iran. Data was collected through intensive semi-structured interviewing and analyzed by a five-step approach applied to phenomenology in psychological research. Data analysis revealed three general themes regarding teachers’ perceptions with several components. We found that the lack of attention and intrinsic motivation were the prominent perceived factors with consequences for TSR. Also, personal talk and active supervision were the common techniques that teachers utilized with students who commit AD to manage and control the TSR quality. The results were discussed with reference to teachers’ academic discipline, gender, and teaching experience. (shrink)

Background: Professional commitment is an important factor in employee performance. COVID-19 outbreak has seriously affected the nurses working conditions. Numerous factors can affect nurses' professional commitment in this situation. Aim: To explore the nurses' lived experiences, attitudes, views and perceptions toward professional commitment and factors affecting it in the Covid-19 crisis. Method, Setting and Participants: This qualitative study was conducted using phenomenological approach and content analysis method. Twenty-five nurses were interviewed using semi structured in-depth interviews. Conventional content analysis was used (...) to analyze collected data. Ethical considerations: Ethical approval was obtained from the Ethics Committee of Qazvin University of Medical Sciences. Results: Five themes were extracted as follows: “Collaborative empathetic commitment”, “Loyal commitment”, “Sacrificial commitment”, “Commitment with doubt and concern” and “humanistic commitment”. Discussion and Conclusion: The Covid-19 crisis has caused major changes in nurses' working conditions, which have also affected the concept of professional commitment to the nursing profession and revealed new concepts. Identifying internal and external factors that can enhance nurses' commitment to the profession in critical situations such as the Covid-19 outback is of particular importance. (shrink)

The productivity of researchers and the impact of the work they do are a preoccupation of universities, research funding agencies, and sometimes even researchers themselves. The h-index is the most popular of different metrics to measure these activities. This research deals with presenting a practical approach to model the h-index based on the total number of citations and the duration from the publishing of the first article. To determine the effect of every factor on h, we applied a set of (...) simple nonlinear regression. The results indicated that both NC and D1 had a significant effect on h. The determination of coefficient for these equations to estimate the h-index was 93.4% and 39.8%, respectively, which verified that the model based on NC had a better fit. Then, to record the simultaneous effects of NC and D1 on h, multiple nonlinear regression was applied. The results indicated that NC and D1 had a significant effect on h. Also, the determination of coefficient for this equation to estimate h was 93.6%. Finally, to model and estimate the h-index, as a function of NC and D1, multiple nonlinear quartile regression was used. The goodness of the fitted model was also assessed. (shrink)

While there has been a number of consumers’ studies looking at factors that influence individuals’ attitudes and behavior toward GM foods, few studies have considered agricultural professionals’ intentions in this regard. This study illuminates agricultural professionals’ insights toward GM foods in Southwest Iran. A random sample of 262 respondents was studied. The results indicated that the majority of the respondents had little knowledge about GM foods. They perceived few benefits or risks of GM foods. Their perceived benefits and trust in (...) individuals and institutions had positive impacts on the behavioral intentions of the agricultural professionals. The results also revealed that the low knowledge level of the respondents had a negative impact on the behavioral intentions toward GM foods. This state of affairs is problematic, either GM foods have serious problems or the knowledge conveyed to the Iranian agricultural experts is inappropriate. We recommend a well defined communication strategy to provide information in such a way that allows individuals to feel adequately informed about GM foods. Furthermore, the development of trust and knowledge regarding GM foods can be greater when risk analysis frameworks are transparent, risk assessment methodologies are objective, all stakeholders are engaged in the risk management process, and risk communication focuses on consumers.

The negative emotions generated following stressful life events can increase one’s risk of depressive symptoms and promote higher levels of perceived stress. The process model of emotion regulation can help distinguish between adaptive and maladaptive emotion regulation strategies to determine who may be at the greatest risk of worse psychological health across the lifespan. Heart rate variability may affect these relationships as it indexes aspects of self-regulation, including emotion and behavioral regulation, that enable an individual to dynamically adapt to the (...) changing demands of both internal and external environments. In this study, we expected individual differences in resting vagally mediated HRV to moderate the influence of emotion regulatory strategies among our sample of 267 adults. We found support for the hypothesis that higher vagally mediated HRV buffers against the typical adverse effects of expressive suppression when evaluating depressive symptoms and found weak support when considering perceived stress. There was no evidence for an interaction between cognitive reappraisal and vagally mediated HRV but there was a significant, negative association between cognitive reappraisal and depressive symptoms and perceived stress. Future work may determine if intervening on either emotion regulation strategies or HRV may change these within-persons over time. (shrink)

In this paper, we study the effects of using an algorithm-based risk assessment instrument (RAI) to support the prediction of risk of violent recidivism upon release. The instrument we used is a machine learning version of RiskCanvi used by the Justice Department of Catalonia, Spain. It was hypothesized that people can improve their performance on defining the risk of recidivism when assisted with a RAI. Also, that professionals can perform better than non-experts on the domain. Participants had to predict whether (...) a person who has been released from prison will commit a new crime leading to re-incarceration, within the next two years. This user study is done with (1) general participants from diverse backgrounds recruited through a crowdsourcing platform, (2) targeted participants who are students and practitioners of data science, criminology, or social work and professionals who work with RisCanvi. We also run focus groups with participants of the targeted study, including people who use RisCanvi in a professional capacity, to interpret the quantitative results. Among other findings, we observe that algorithmic support systematically leads to more accurate predictions from all participants, but that statistically significant gains are only seen in the performance of targeted participants with respect to that of crowdsourced participants. Among other comments, professional participants indicate that they would not foresee using a fully-automated system in criminal risk assessment, but do consider it valuable for training, standardization, and to fine-tune or double-check their predictions on particularly difficult cases. We found that the revised prediction by using a RAI increases the performance of all groups, while professionals show a better performance in general. And, a RAI can be considered for extending professional capacities and skills along their careers. (shrink)

The Gamer’s Dilemma challenges us to justify the moral difference between enacting virtual murder and virtual child molestation in video games. The Dilemma relies for its argumentative force on the claim that there is an intuitive moral difference between these acts, with the former intuited as morally acceptable and the latter as morally unacceptable. However, there has been no empirical investigation of these claims. To explore these issues, we developed an experimental survey study in which participants were asked to reflect (...) on imaginary video game scenarios as part of a 2 (undertake virtual murder or molestation) X 2 (against an adult or child) X 2 (in a high or low realism virtual environment) factorial design. We found that there was a significant difference between people’s views about virtual murder and virtual molestation. Whether the virtual act was performed against an adult or child was non-significant in most conditions, whereas whether it was performed in a high or low realism virtual environment was significant in most conditions. Gender did not impact these results, whereas perceived gaming experience, hours of video game play per week, and integrity did. These results provide an empirical grounding for future discussions of the Gamer's Dilemma. (shrink)

Background: Lower limb spasticity after stroke is common that can affect the balance, increase the risk of falling, and reduces the quality of life.Objective: First, evaluate the effects of spasticity severity of ankle plantar flexors on balance of patients after stroke. Second, to determine the relationship between the spasticity severity with ankle proprioception, passive ankle dorsiflexion range of motion, and balance confidence.Methods: Twenty-eight patients with stroke based on the Modified Modified Ashworth Scale were divided into two groups: High Spasticity Group (...) or a Low Spasticity Group. The MMAS scores, Activities-Specific Balance Confidence Questionnaire, postural sway of both affected and non-affected limbs under the eyes open and eyes closed conditions, timed up and go test, passive ankle dorsiflexion ROM, and ankle joint proprioception were measured.Results: The ankle joint proprioception was significantly better in the LSG compared to the HSG. No significant differences were found between the LSG and HSG on all other outcome measures. There were no significant relationships between the spasticity severity and passive ankle dorsiflexion ROM, and balance confidence.Conclusion: The severity of ankle plantar flexor spasticity had no effects on balance of patients with stroke. However, the ankle joint proprioception was better in patients with low spasticity. Our findings suggest that the balance is affected regardless of the severity of the ankle plantar flexor spasticity in this group of participants with stroke. (shrink)

La présente recherche s’intéresse à l’impact du contexte phonétique sur les formants 1, 2 et 3 des voyelles nasales françaises. La chaine parlée en français est constituée de la succession des voyelles orales et nasales influencées par le contexte consonantique. En nous appuyant, dans cette étude, sur le modèle de Stevens et House, dit « production undershoot model »,nous avons abordé plus particulièrement l’effet du contexte phonétique sur les trois voyelles nasales françaises afin de vérifier l’hypothèse suivante : dans le (...) contexte phonétique, la consonne influerait, non seulement, sur le formant 1 et 2 mais aussi sur le formant nasal de la voyelle nasale et elle l’écarte de son propre « hyperespace », bien qu’elle ne bannisse pas l’anti-formant. Pour vérifier notre hypothèse, nous avons analysé les productions phonétiques de 4 étudiants de français de première année de l’université d’Ispahan à l’aide d’un logiciel d’analyse de sons tout en tenant compte des variables acousti...

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.
