BackgroundThe nursing profession requires ethical and legal regulations to guide nurses’ performance. Ethical climate plays a part in shaping nurses’ ethical practice. Therefore, ethico-legal aspects and ethical climate contribute to improving nurses’ ethical practice and competencies with reducing medical errors in hospital settings.ObjectiveThis study examined the effect of ethico-legal aspects and ethical climate on managing safe patient care and medical errors among nurses.Materials and methodsA cross-sectional correlational study was carried out on 548 nurses. Data were collected through self-administered questionnaires about (...) nurses’ knowledge in both ethical and legal aspects, ethical practice, competencies, ethical climate and experience with medical error.ResultsThe main sources of nurses’ knowledge of ethical and legal aspects were undergraduate lectures, job experience and colleagues. Nurses’ knowledge in both ethical and legal aspects, nurses’ ethical practice and competencies were insufficient. Nurses fairly perceived their ethical climate. Also, nurses experienced medical errors about 22.6% in their units. Nurses’ knowledge of ethical and legal aspects, as well as the ethical climate were positive predictors of inadequate nurses’ ethical practice and competencies. Additionally, nurses’ knowledge in both ethical and legal aspects, ethical climate and practice had a negative influence on the occurrence of medical errors.ConclusionEnhancing nurses’ knowledge in both ethical and legal aspects as well as ethical climate could significantly influence improving nurses’ ethical practice, competencies and reducing medical errors in the study units. Therefore, planning for enhancing the nurses’ ethico-legal learning and ethical climate seems to be mandatory. (shrink)

BackgroundObstetrics and gynaecology always has reputation for being a highly litigious. The field of obstetrics and gynaecology is surrounded by different circumstances that stimulate the doctors to practice defensive medicine.MethodsThis study was directed to assess the extent and the possible effect of defensive medicine phenomenon on medical decision making among different grades of obstetric and gynaecologic Sudanese doctors, and to determine any experience of medical litigations with respect to sources and factors associated with it.ResultsA total of 117 doctors were approached, (...) their distribution according to job description was as follow: consultants registrars and specialists. The majority 89.7 % had the impression that litigation against doctors are increasing and 27.6 % had a direct experience of litigation. In this study less than one half of the surveyed doctors knew the concept of defensive medicine and 71.8 % reported practicing one or another form of defensive medicine. The different sources of the litigations reported by the doctors included: maternal death, perinatal death, other {misdiagnosis, intra-uterine fetal death, uterine perforation, rupture uterus}, fetal distress, injury to viscera and shoulder dystocia. In this study the experience of medical litigation was significantly observed among those who worked in area of blame culture. In logistic regression model, there was no significant difference between those who knew the concept of defence medicine and those who didn’t.ConclusionThere should be strategic plan to reduce the practice of defensive medicine and medical litigation against doctors.

© 2015 Elsevier Inc.Toxoplasma gondii is a protozoan pathogen in the phylum Apicomplexa that resides within an intracellular parasitophorous vacuole that is selectively permeable to small molecules through unidentified mechanisms. We have identified GRA17 as a Toxoplasma-secreted protein that localizes to the parasitophorous vacuole membrane and mediates passive transport of small molecules across the PVM. GRA17 is related to the putative Plasmodium translocon protein EXP2 and conserved across PV-residing Apicomplexa. The PVs of GRA17-deficient parasites have aberrant morphology, reduced permeability to (...) small molecules, and structural instability. GRA17-deficient parasites proliferate slowly and are avirulent in mice. These GRA17-deficient phenotypes are rescued by complementation with Plasmodium EXP2. GRA17 functions synergistically with a related protein, GRA23. Exogenous expression of GRA17 or GRA23 alters the membrane conductance properties of Xenopus oocytes in a manner consistent with a large non-selective pore. Thus, GRA17 and GRA23 provide a molecular basis for PVM permeability and nutrient access. (shrink)

Arab and English cultures are incongruent, where the former is greatly influenced by religion when compared to the latter. This study focuses on court interpreting from Arabic into English and questions the interpreters’ objectivity when rendering religious and cultural expressions, bearing in mind that certain cultures, like the Arab and Muslim ones, have significant religious ties. To this end, fifteen transcripts were randomly collected from Canadian court hearings. The analysis showed that interpreting religious and cultural expressions can be complex, especially (...) when the original speaker attempts to transmit a notion that may have negative implications in the target language. The results also showed that court interpreters either added explanations to religious and cultural expressions or omitted them. Such additions and omissions may be used to avoid negative stereotypes other cultures have about Muslims and Arabs. The study recommends that future researchers interested in legal interpreting consider the non-verbal factors that can be observed during court hearings. The study suggests allocating extensive training sessions to interpreters on how to impartially render culture-bound expressions, mainly in the legal context. (shrink)

Recent studies from Western countries indicate significant levels of questionable research practices, but similar data from low and middle-income countries are limited. Our aims were to assess the prevalence of and attitudes regarding research misconduct among researchers in several universities in the Middle East and to identify factors that might account for our findings. We distributed an anonymous questionnaire to a convenience sample of investigators at several universities in Egypt, Lebanon, and Bahrain. Participants were asked to a) self-report their extent (...) of research misconducts, as well as their knowledge of colleagues engaging in similar research misconducts and b) provide their extent of agreement with certain attitudes about research misconduct. We used descriptive, bivariate, and multivariate logistic regression statistics to analyze the data. Data from 278 participants showed a high prevalence of misconduct, as 59.4% of our respondents self-reported to committing at least one misbehaviors and 74.5% reported having knowledge of any misbehaviors among any of their colleagues. The most common type of self-report misconduct was “circumventing research ethics regulations” followed by “fabrication and falsification”. A significant predictor of misconduct included a lack of “prior ethics training”. Scientific misconduct represents a significant issue in several universities in the Middle East. The demonstration that a lack of “prior ethics training” was a significant predictor of misconduct should lead to educational initiatives in research integrity. Further studies are needed to confirm whether our results can be generalized to other universities in the Middle East. (shrink)

The rapid growth of covert activities via communications network brought about an increasing need to provide an efficient method for data hiding to protect secret information from malicious attacks. One of the options is to combine two approaches, namely steganography and compression. However, its performance heavily relies on three major factors, payload, imperceptibility, and robustness, which are always in trade-offs. Thus, this study aims to hide a large amount of secret message inside a grayscale host image without sacrificing its quality (...) and robustness. To realize the goal, a new two-tier data hiding technique is proposed that integrates an improved exploiting modification direction method and Huffman coding. First, a secret message of an arbitrary plain text of characters is compressed and transformed into streams of bits; each character is compressed into a maximum of 5 bits per stream. The stream is then divided into two parts of different sizes of 3 and 2 bits. Subsequently, each part is transformed into its decimal value, which serves as a secret code. Second, a cover image is partitioned into groups of 5 pixels based on the original EMD method. Then, an enhancement is introduced by dividing the group into two parts, namely k1 and k2, which consist of 3 and 2 pixels, respectively. Furthermore, several groups are randomly selected for embedding purposes to increase the security. Then, for each selected group, each part is embedded with its corresponding secret code by modifying one grayscale value at most to hide the code in a -ary notational system. The process is repeated until a stego-image is eventually produced. Finally, the χ2 test, which is considered one of the most severe attacks, is applied against the stego-image to evaluate the performance of the proposed method in terms of its robustness. The test revealed that the proposed method is more robust than both least significant bit embedding and the original EMD. Additionally, in terms of imperceptibility and capacity, the experimental results have also shown that the proposed method outperformed both the well-known methods, namely original EMD and optimized EMD, with a peak signal-to-noise ratio of 55.92 dB and payload of 52,428 bytes.

BackgroundIn clinical research, obtaining informed consent from participants is an ethical and legal requirement. Conveying the information concerning the study can be done using multiple methods yet this step commonly relies exclusively on the informed consent form alone. While this is legal, it does not ensure the participant’s true comprehension. New effective methods of conveying consent information should be tested. In this study we compared the effect of different methods on the knowledge of caregivers of participants of a clinical trial (...) on Pemba Island, Tanzania.MethodsA total of 254 caregivers were assigned to receive a pamphlet, an oral information session or a pamphlet and an oral information session about the clinical trial procedures, their rights, benefits and potential risks. Their post-intervention knowledge was assessed using a questionnaire. One group of caregivers had not received any information when they were interviewed.ResultsIn contrast to the pamphlet, attending an information session significantly increased caregivers’ knowledge for some of the questions. Most of these questions were either related to the parasite or to the trial design.ConclusionsIn conclusion, within our trial on Pemba Island, a pamphlet was found to not be a good form of conveying clinical trial information while an oral information session improved knowledge. Not all caregivers attending an information session responded correctly to all questions; therefore, better forms of communicating information need to be found to achieve a truly informed consent.

The application of recycled aggregate as a sustainable material in construction projects is considered a promising approach to decrease the carbon footprint of concrete structures. Prediction of compressive strength of environmentally friendly concrete containing recycled aggregate is important for understanding sustainable structures’ concrete behaviour. In this research, the capability of the deep learning neural network approach is examined on the simulation of CS of EF concrete. The developed approach is compared to the well-known artificial intelligence approaches named multivariate adaptive regression (...) spline, extreme learning machines, and random forests. The dataset was divided into three scenarios 70%-30%, 80%-20%, and 90%-10% for training/testing to explore the impact of data division percentage on the capacity of the developed AI model. Extreme gradient boosting was integrated with the developed AI models to select the influencing variables on the CS prediction. Several statistical measures and graphical methods were generated to evaluate the efficiency of the presented models. In this regard, the results confirmed that the DLNN model attained the highest value of prediction performance with minimal root mean squared error. The study revealed that the highest prediction performance could be attained by increasing the number of variables in the prediction problem and using 90%-10% data division. The results demonstrated the robustness of the DLNN model over the other AI models in handling the complex behaviour of concrete. Due to the high accuracy of the DLNN model, the developed method can be used as a practical approach for future use of CS prediction of EF concrete. (shrink)

In recent years, network security has become a major concern. Using the Internet to store and analyze data has become an integral aspect of the production and operation of many new and traditional enterprises. However, many enterprises lack the necessary resources to secure information security, and selecting the best network security service provider has become a real issue for many enterprises. This research introduces a novel decision-making method utilizing the 2-tuple linguistic complex q-rung orthopair fuzzy numbers to tackle this issue. (...) We propose the 2TLCq-ROF concept by combining the complex q-rung orthopair fuzzy set with 2-tuple linguistic terms, including the fundamental definition, operational rules, scoring, and accuracy functions. Aggregation operators are the fundamental mathematical approach used to combine various inputs into a single output. Taking into account the interaction between the attributes, we develop the 2TLCq-ROF Hamacher operators by using the innovative operational rules. These operators include the 2TLCq-ROFH weighted average, 2TLCq-ROFH ordered weighted average, 2TLCq-ROFH hybrid average, 2TLCq-ROFH weighted geometric, 2TLCq-ROFH ordered weighted geometric, and 2TLCq-ROFH hybrid geometric operators. In addition, we talk about the properties of 2TLCq-ROFH operators such as idempotency, commutativity, monotonicity, and boundedness and also examine their spatial cases. To tackle the problems of the 2TLCq-ROF multiattribute group decision-making environment, we develop a novel approach according to the COPRAS model. Finally, to validate the feasibility of the given strategy, we employ a quantitative example related to select the best network security service provider. In comparison with existing approaches, the developed decision-making algorithm is most extensively used and reduces the loss of information. (shrink)

Background The consistency of codes governing disclosure of terminal illness to patients and families in Islamic countries has not been studied until now. Objectives To review available codes on disclosure of terminal illness in Islamic countries. Data source and extraction Data were extracted through searches on Google and PubMed. Codes related to disclosure of terminal illness to patients or families were abstracted, and then classified independently by the three authors. Data synthesis Codes for 14 Islamic countries were located. Five codes (...) were silent regarding informing the patient, seven allowed concealment, one mandated disclosure and one prohibited disclosure. Five codes were silent regarding informing the family, four allowed disclosure and five mandated/recommended disclosure. The Islamic Organization for Medical Sciences code was silent on both issues. Conclusion Codes regarding disclosure of terminal illness to patients and families differed markedly among Islamic countries. They were silent in one-third of the codes, and tended to favour a paternalistic/utilitarian, family-centred approach over an autonomous, patient-centred approach. (shrink)

Research Ethics, Volume 18, Issue 4, Page 265-280, October 2022. Concerns around comprehension and recall of consent information by research participants have typically been associated with low health and research literacy levels. In genomics research, this concern is heightened as the scientific and ethical complexities of genetics research, such as biobanking, genetic susceptibility, data sharing, and incidental findings may be more difficult for potential research participants to understand. However, challenges to research participants’ comprehension of consent information may be compounded by (...) factors beyond health and research literacy levels. To identify factors that may impact research participants’ understanding and recall of consent information, we designed a qualitative study to explore whether participants enrolled in a tuberculosis genetics study in Cameroon understood the objectives of the study, the risks and benefits and certain key aspects of the study such as biobanking and data sharing. The results showed that research participants had limited understanding and/or recall of the TBGEN-Africa study goals and methods. Some participants were of the opinion that TBGEN-Africa was not a genetics study because tuberculosis is not an inheritable condition. Factors that may have hindered understanding and/or recall of study information are diagnostic misconception, and information overload and situational vulnerability. There is a need for improved practices to support research participants’ understanding of consent information in genetics studies including designing the consent process in ways that minimize psychological distress and diagnostic/therapeutic misconception.

Mansour Fahmy, one of the dramatic figures in modern Arab philosophical and social thought. He was the reformist and enlightenment figure in modern Arab history. He is also the owner of a notable current that was subjected to a violent attack that silenced him for a long time and forced him to "hide" physically. However, this did not eliminate the new opinions and positions that came at the beginning of the twentieth century towards the issue of women. He is the (...) first to write with a scientific methodology - from the point of view of sociology - on Islamic discourse and its dealings with women. he sought to differentiate between religion and the religious establishment, between the personality of the Prophet Muhammad and what later prevailed in the books of jurisprudence and others. When he discussed the headscarf issue, he concluded that it was the product of traditions and customs that the Hijab is not from the Islamic religion. Islamic law has nothing to do with the Hijab. Mansour Fahmy's creativity was at one of the sensitive stages in Egypt's modern history in which the political, social, national, cultural, and revolution clashed in each one. All this, in turn, identified the problem of Mansour Fahmy's intellectual personality in the battles of thought and politics. This research's main task is to redraw the features of his actual personality and the reality of his intellectual, social, and political positions. Besides, this study seeks to uncover the effect of philosophy on crystallizing Mansour Fahmy's critical personality and its role in laying the foundations of the critical vision with its practical, reformist, and enlightening dimensions.

Joseph Medill's Chicago Tribune was an influential voice for civil rights and equality in the age of slavery. By 1883, however, when the Supreme Court struck down the Civil Rights Act of 1875, the Tribune 's commitment to its moral principles had been compromised. The paper abandoned its editorial support for equality in favor of shoring up the declining fortunes of the Republican Party in the post-Reconstruction era. A content analysis of Tribune news and editorial items on the civil rights (...) law shows strong support for the statute in 1875 when it was passed, and an equally strong support for the Supreme Court decision that annulled it in 1883.

This article proposes a new problem which is called the Stochastic Travelling Advisor Problem in network optimization, and it is defined for an advisory group who wants to choose a subset of candidate workplaces comprising the most profitable route within the time limit of day working hours. A nonlinear binary mathematical model is formulated and a real application case study in the occupational health and safety field is presented. The problem has a stochastic nature in travelling and advising times since (...) the deterministic models are not appropriate for such real-life problems. The STAP is handled by proposing suitable probability distributions for the time parameters and simulating the problem under such conditions. Many application problems like this one are formulated as nonlinear binary programming models which are hard to be solved using exact algorithms especially in large dimensions. A novel binary version of the recently developed gaining-sharing knowledge-based optimization algorithm to solve binary optimization problems is given. GSK algorithm is based on the concept of how humans acquire and share knowledge during their life span. The binary version of GSK depends mainly on two stages that enable BGSK for exploring and exploitation of the search space efficiently and effectively to solve problems in binary space. The generated simulation runs of the example are solved using the BGSK, and the output histograms and the best-fitted distributions for the total profit and for the route length are obtained.

Whooping cough is a highly transmitted disease around the world. According to the World Health Organization, 0.15 million cases had reported globally in 2018. Most of the Asian and African states are infected regions. Through the study, we investigated the whole population into the four classes susceptible, exposed, infected, and vaccinated or recovered. The transmission dynamics of whooping cough disease are studied analytically and numerically. Analytical analyses are positivity, boundedness, reproduction number, equilibria, and local and global stabilities. In numerical analysis, (...) we developed an implicit numerical integration scheme consistent with the biological problem’s properties. The analysis of the implicit method for the said model is dynamically consistent, positive, and bounded. Furthermore, an implicit numerical integration scheme is suitable for studying a particular epidemic model such as the whooping cough disease. (shrink)

In the past few decades, a lot of optimization methods have been applied in estimating the parameter of photovoltaic models and obtained better results, but these methods still have some deficiencies, such as higher time complexity and poor stability. To tackle these problems, an enhanced success history adaptive DE with greedy mutation strategy is employed to optimize parameters of PV models to propose a parameter optimization method in this paper. In the EBLSHADE, the linear population size reduction strategy is used (...) to gradually reduce population to improve the search capabilities and balance the exploitation and exploration capabilities. The less and more greedy mutation strategy is used to enhance the exploitation capability and the exploration capability. Finally, a parameter optimization method based on EBLSHADE is proposed to optimize parameters of PV models. The different PV models are selected to prove the effectiveness of the proposed method. Comparison results demonstrate that the EBLSHADE is an effective and efficient method and the parameter optimization method is beneficial to design, control, and optimize the PV systems. (shrink)

Juridical councils that render rulings on bioethical issues for Muslims living in non-Muslim lands may have limited familiarity with the foundational concept of wilāyah (authority and governance) and its implications for their authority and functioning. This paper delineates a Sunni Māturīdi perspective on the concept of wilāyah, describes how levels of wilāyah correlate to levels of responsibility and enforceability, and describes the implications of wilāyah when applied to Islamic bioethical decision making. Muslim health practitioners and patients living in the absence (...) of political wilāyah may be tempted to apply pragmatic and context-focused approaches to address bioethical dilemmas without a full appreciation of significant implications in the afterlife. Academic wilāyah requires believers to seek authentication of uncertain actions through scholarly opinions. Fulfilling this academic obligation naturally leads to additional mutually beneficial discussions between Islamic scholars, healthcare professionals, and patients. Furthermore, an understanding derived from a Māturīdi perspective provides a framework for Islamic scholars and Muslim health care professionals to generate original contributions to mainstream bioethics and public policy discussions.

BackgroundBurnout is a syndrome that results from stressors in the work environment that have not been successfully managed. The prevalence of burnout among schoolteachers was always controversial. COVID-19 pandemic added more stressors to teachers since they had to change their working styles in response to the pandemic lockdowns or curfews. In Saudi Arabia, the prevalence and determinants of burnout among school teachers were not measured by any other group during the COVID-19 pandemic stressors.MethodsA cross-sectional survey was conducted among 879 teachers (...) in the Jazan region, Saudi Arabia, using the Maslach Burnout Inventory, during April 2021. Multistage cluster random sampling was used.ResultsThe mean age of the participants was 41.4 years. Male teachers represented 52.6% of the participants while females represented 47.4%. Most teachers showed burnout symptoms. Consequences of burnout were observed, such as using psychotropic medications, absenteeism, lack of job satisfaction, and changing schools. Using the MBI scale, most teachers showed medium or high emotional exhaustion, low depersonalization, and low personal accomplishment.ConclusionMost teachers showed symptoms of burnout during the COVID-19 pandemic. Being an expert and ability to adapt to technology during the COVID-19 pandemic proved to effectively reduce burnout symptoms. Increasing incentives, early detection, and improving the work environment is recommended to diminish burnout consequences. (shrink)

Social entrepreneurship orientation is a behavioral construct of social entrepreneurship ; therefore, we examined the influence of SEO of the organization on social and financial performance. A random sample of 810 employees was drawn from social enterprises of Pakistan during the COVID-19 pandemic. Although increasing research focuses on SE, the discipline continues to disintegrate, and this has led to appeals for a careful investigation of the associations of firms’ SE. In the recent decade, “social entrepreneurship” has earned its importance as (...) a segment of entrepreneurship. Instead of mixed activity, firms are more likely to engage in either for-profit or non-profit activities. The causes for and consequences of this conduct has been mainly studied using objective measures of SEO, social performance, and financial performance, with little attention paid to the subjective experiences of social enterprises. We rely on the theory of stakeholder and mixed structuring to postulate that social performance intermediates the SEO-financial performance relation. By assessing a sample of 810 employees from active enterprises, we discover that social performance mediates positively and partially between SEO and financial performance, and both direct and indirect paths are in the same direction and significant. Our findings exhibit that social performance variance explained 74% of the mediating role, and the remaining 26% of the effect is because of SEO. We consider the functions by which an SEO influences enterprise performance and delivers more prominent understanding into multiple spectrums of performance. We discuss the prospective suggestions of our research and foster an encouraging pathway for more enquiry on the SEO paradigm. The study adds contribution to the literature, which has not been testified before on hybrid firms. SEO is a newly defined construct and requires more prospective research. This research gives the researchers/scholars new directions to address related disciplines and further explore this domain. (shrink)
