This study examines the subtle and complex importance of food and eating in contemporary female fiction. It reveals how the chief concern with food, its consumption and the body are central to the work of writer like Margaret Atwood. Two novels in particular, Cat’s Eye (1988) and Alias Grace (1996) will be considered as they feature female protagonists who experience intense conflicts concerning their bodies, conflicts that result in or are a response to violence. This violence takes the form of (...) eating disorders. They highlight this form of bodily violence which supports their on going critique of dualistic thinking. In their fictions, Atwood shows the artificial bifurcation of human existence into body and self which tends to result in self-alienation or the splitting of the subject. This writer draws on feminist and sociological theory to engage with a diverse range of issues, including eating disorders as a form of self-violence or mutilation, to demonstrate the direct relationship of food and eating or not-eating with gender and cultural politics to manifest the role of using food in assumed association of the womanly body which leads to splitting of the subject.

This study examines local communities’ lived experiences and organizations’ care-giving processes regarding four oil and gas projects deployed in three countries. Analyzing the empirical data through the lens of ethics of care reveals that, together with mature justice, the inclination to care conceived at the focal organization creates an ethical culture encouraging caring activities by individuals at the local level. Through close communications with communities, project decision makers at the local level recognize the demanded care of local communities and develop (...) organizations’ caring capacity. The empirical analysis revealed that the care-giving process can also be influenced by the power dynamics of the network of stakeholders. This research emphasizes on the success of a bottom-up approach in caring for local communities, and sheds light on the capability of large organizations in giving care to their distal stakeholders by adopting this approach. Furthermore, it indicates that justice and care both have some useful characteristics and are complementary but, most importantly, are socially constructed and not mutually exclusive. (shrink)

Background Since the beginning of the COVID-19 pandemic, different countries sought to manufacture and supply effective vaccines to control the disease and prevent and protect public health in society. The implementation of vaccination has created many ethical dilemmas for humans, which must be recognized and resolved. Therefore, the present study was conducted to analyze the ethical considerations in vaccination against COVID-19 from the perspective of service providers. Methods The present qualitative research was conducted in 2022 in the north of Iran. (...) The participants included 23 health workers with at least five years of work experience and members of the COVID-19 vaccination team. The data were initially collected through systematic semi-structured interviews, then snowball sampling and finally continued until data saturation. The next steps were transcription of interviews, identification of meaning units, coding, categorization based on similarity and symmetry, extraction of themes and the analysis of themes through content analysis. Results The analysis of participants’ experiences led to the extraction of five main categories of themes and fifteen sub-categories of the ethical considerations of COVID-19 vaccination. Safe and standard vaccine production, vaccine supply, fairness, respect for autonomy, and accountability were the main categories. The subcategories included compliance with scientific and ethical procedures, effectiveness and profitability of vaccine, absence of severe adverse effects, allocation of resources for vaccine supply, vaccine availability, diversity and comprehensiveness of alternative vaccines, vaccination prioritization, prioritization of the vulnerable populations of society, autonomy of patient (equal rights), autonomy of community, autonomy of service providers, reporting correct information, reporting vaccine side effects, public trust and acceptance. Conclusion The health system managers should be adequately prepared to solve the ethical problems posed by COVID-19 vaccination. Therefore, it is recommended to avoid haste in vaccination and pay more attention to vaccination safety standards, provide sufficient resources for a comprehensive vaccine supply, pay close attention to collective interests versus individual interests, and meet community needs.

Contract cheating is a challenging problem facing higher and further education providers (HE and FE) worldwide. In the UK, contract cheating has been identified as a growing problem by the HEA and, more recently, the Quality Assurance Agency for Higher Education and the Department for Education. The high rate of contact cheating among students suggests that 8–9% of degrees awarded in the UK are unsafe. To address this issue, the current study with a new approach seeks to investigate student’s motivations, (...) experiences, and rationale for using contract cheating from their point of view. Collected data has been subjected to content analysis and the findings show different phases and drivers in this process. This study will help increase awareness among UK academics and education providers about the processes involved in contract cheating and propose a set of recommendations for the future. (shrink)

The aviation industry is one of the most widely used applications in transportation. Due to the limited capacity of aircraft, revenue management in this industry is of high significance. On the other hand, the hub location problem has been considered to facilitate the demands assignment to hubs. This paper presents an integrated p-hub location and revenue management problem under uncertain demand to maximize net revenue and minimize total cost, including hub establishment and transportation costs. A fuzzy programming model and a (...) genetic algorithm are developed to solve the proposed model with different sizes. The mining and petroleum industry is used for case studies. Results show that the proposed algorithm can obtain a suitable solution in a reasonable amount of time. (shrink)

Background: Moral reasoning is a vital skill in the nursing profession. Teaching moral reasoning to students is necessary toward promoting nursing ethics. Objectives: The aim of this study was to compare the effectiveness of problem-based learning and lecture-based methods in ethics education in improving moral decision-making, moral reasoning, moral development, and practical reasoning among nursing students. Research design: This is a repeated measurement quasi-experimental study. Participants and research context: The participants were nursing students in a University of Medical Sciences in (...) west of Iran who were randomly assigned to the lecture-based or the problem-based learning groups. The subjects were provided nursing ethics education in four 2-h sessions. The educational content was similar, but the training methods were different. The subjects completed the Nursing Dilemma Test before, immediately after, and 1 month after the training. The data were analyzed and compared using the SPSS-16 software. Ethical considerations: The program was explained to the students, all of whom signed an informed consent form at the baseline. Findings: The two groups were similar in personal characteristics. A significant improvement was observed in the mean scores on moral development in the problem-based learning compared with the lecture-based group. Although the mean scores on moral reasoning improved in both the problem-based learning and the lecture-based groups immediately after the training and 1 month later, the change was significant only in the problem-based learning group. The mean scores on moral decision-making, practical considerations, and familiarity with dilemmas were relatively similar for the two groups. Conclusion: The use of the problem-based learning method in ethics education enhances moral development among nursing students. However, further studies are needed to determine whether such method improves moral decision-making, moral reasoning, practical considerations, and familiarity with the ethical issues among nursing students.

Ras proteins function as critical relay switches that regulate diverse signaling pathways between cell surface receptors and the nucleus. Over the past 2‐3 years researchers have identified many components of these pathways that mediate Ras activation and effector function. Among these proteins are several guanine nucleotide exchange factors (GEFs), which are responsible for directly interacting with and activating Ras in response to extracellular stimuli. Analogous GEFs regulate Ras‐related proteins that serve other diverse cellular functions. In particular, a growing family of (...) proteins (Dbl homology proteins) has recently been identified, which may function as GEFs for the Rho family of Ras‐related proteins. This review summarizes our current knowledge of the structure, biochemistry and biology of Ras and Rho family GEFs. Additionally, we describe mechanisms of GEF activation of Ras in signal transduction and address the potential that deregulated GEFs might contribute to malignant transformation through chronic Ras protein activation.

Background Providing quality care is of the fundamental elements of holistic nursing practice, and burnout and moral intelligence of nurses be mentioned as the important factors influencing the quality of nursing care. The present study was conducted to investigate the relationship between moral intelligence, burnout, and the quality of nursing care. Methods This descriptive-correlative study was conducted on 125 nurses working in Sari-based Educational hospitals affiliated to Mazandaran University of Medical Sciences, Iran, between June and August 2020. The sample was (...) selected via random sampling. The data were collected by the Maslach Burnout Inventory, Lennick and Kiel Moral Intelligence Scale, and Quality of Patient Care Scale. The data were analyzed by SPSS-21 and Amos-24. Results A direct and significant relationship was found between the quality of nursing care and moral intelligence ( r = 0.285, p = 0.001). Quality of care had an inverse relationship with subscales of frequency of burnout including emotional exhaustion ( r = −0.369, p < 0.001) and depersonalization ( r = −0.471, p < 0.001) and also, a direct relationship with personal accomplishment ( r = 0.226, p = 0.011). The findings also showed an inverse relationship between quality of care and subscales of the intensity of burnout. Amos software yielded results that demonstrated moral intelligence as a robust mediator between burnout and the quality of care. Conclusion The findings implied the necessity for more attention to moral intelligence as a mediator in order to come up with properly managing the personality traits influencing the nurses’ burnout reduction, which can ultimately lead to improved quality of nursing care.
