We study punctual categoricity on a cone and intrinsically punctual functions and obtain complete structural characterizations in terms of model-theoretic notions. As a corollary, we answer a question of Bazhenov, Downey, Kalimullin, and Melnikov by showing that relational structures are not punctually universal. We will also apply this characterisation to derive an algebraic characterisation of relatively punctually categorical mono-unary structures.

There is a global shortage of nurses that affects healthcare delivery, which will be exacerbated with the increasing demand for healthcare professionals by the aging population. The growing shortage requires an ethical exploration on the issue of nurse migration. In this article, we discuss how migration respects the autonomy of nurses, increases cultural diversity, and leads to improved patient satisfaction and health outcomes. We also discuss the potential for negative impacts on public health infrastructures, lack of respect for cultural diversity, (...) and ethical concerns related to autonomy and justice, including coercion and discrimination. This analysis is written from a rights-based ethics approach by referring to rights held by nurses and patient populations. Nurse migration highlights conflicts between nurses and between nurses and healthcare systems. Increased awareness of ethical challenges surrounding nurse migration must be addressed to enhance the well-being of nurses and patient populations. (shrink)

We prove that the degree structures of the d.c.e. and the 3-c.e. Turing degrees are not elementarily equivalent, thus refuting a conjecture of Downey. More specifically, we show that the following statement fails in the former but holds in the latter structure: There are degrees f > e > d > 0 such that any degree u ≤ f is either comparable with both e and d, or incomparable with both.

Marsilio Ficino’s fame as a translator, not least due to his contributions to theology and the development of hermeticism, has already been established by Frances Yates and debated by Wouter Hanegraaff. For each of his translations of Greek texts, Ficino wrote a preface to guide and to manipulate the reader. This paper presents an analysis of the auctoritas in the paratext of the Corpus Hermeticum, analyzing it as a rhetorical device used by Ficino to express his ideas, particularly the role (...) of Hermes Trismegistus. Ficino used his rhetorical skill not only to translate from Greek to Latin but also to support his theories in commentaries, letters, or, in this case, prefaces. (shrink)

We analyze the degree spectra of structures in which different types of immunity conditions are encoded. In particular, we give an example of a structure whose degree spectrum coincides with the hyperimmune degrees. As a corollary, this shows the existence of an almost computable structure of which the complement of the degree spectrum is uncountable.

Defining the degree of categoricity of a computable structure ${\mathcal{M}}$ to be the least degree d for which ${\mathcal{M}}$ is d-computably categorical, we investigate which Turing degrees can be realized as degrees of categoricity. We show that for all n, degrees d.c.e. in and above 0 (n) can be so realized, as can the degree 0 (ω).

We show that the Δ0 2 enumeration degrees are dense. We also show that for every nonzero n-c. e. e-degree a, with n≥ 3, one can always find a nonzero 3-c. e. e-degree b such that b < a on the other hand there is a nonzero ωc. e. e-degree which bounds no nonzero n-c. e. e-degree.

We extend the limitwise monotonicity notion to the case of arbitrary computable linear ordering to get a set which is limitwise monotonic precisely in the non‐computable degrees. Also we get a series of connected non‐uniformity results to obtain new examples of non‐uniformly equivalent families of computable sets with the same enumeration degree spectrum.

We introduce a hierarchy of sets which can be derived from the integers using countable collections. Such families can be coded into countable algebraic structures preserving their algorithmic properties. We prove that for different finite levels of the hierarchy the corresponding algebraic structures have different classes of possible degree spectra.

Background The global COVID-19 pandemic has challenged nurse leaders in ways that one could not imagine. Along with ongoing priorities of providing high quality, cost-effective and safe care, nurse leaders are also committed to promote an ethical climate that support nurses’ moral courage for sustaining excellence in patient and family care. Aim This study is directed to develop a structure equation model of crisis, ethical leadership and nurses’ moral courage: mediating effect of ethical climate during COVID-19. Ethical consideration Approval was (...) obtained from Ethics Committee at Faculty of Nursing, Alexandria University, Egypt. Methods A cross-sectional design was used to conduct this study using validated scales to measure the study variables. It was conducted in all units of two isolated hospitals in Damanhur, Egypt. A convenient sample of 235 nurses was recruited to be involved in this study. Results This study revealed that nurses perceived a moderate mean percent (55.49 ± 3.46) of overall crisis leadership, high mean percent (74.69 ± 6.15) of overall ethical leadership, high mean percent (72.09 ± 7.73) of their moral courage, and moderate mean percent of overall ethical climate (65.67 ± 12.04). Additionally, this study declared a strong positive statistical significant correlation between all study variables and indicated that the independent variable (crisis and ethical leadership) can predict a 0.96, 0.6, respectively, increasing in the dependent variable (nurses’ moral courage) through the mediating impact of ethical climate. Conclusion Nursing administrators should be conscious of the importance of crisis, ethical leadership competencies and the role of ethical climate to enhance nurses’ moral courage especially during pandemic. Therefore, these findings have significant contributions that support healthcare organizations to develop strategies that provide a supportive ethical climate. Develop ethical and crisis leadership competencies in order to improve nurses' moral courage by holding meetings, workshops, and allowing open dialogue with nurses to assess their moral courage.

For a computable structure $\mathcal {M}$, the categoricity spectrum is the set of all Turing degrees capable of computing isomorphisms among arbitrary computable copies of $\mathcal {M}$. If the spectrum has a least degree, this degree is called the degree of categoricity of $\mathcal {M}$. In this paper we investigate spectra of categoricity for computable rigid structures. In particular, we give examples of rigid structures without degrees of categoricity.

The survey contains a detailed discussion of methods and results in the new emerging area of online “punctual” structure theory. We also state several open problems.

Recall that B is PA relative to A if B computes a member of every nonempty $\Pi ^0_1(A)$ class. This two-place relation is invariant under Turing equivalence and so can be thought of as a binary relation on Turing degrees. Miller and Soskova [23] introduced the notion of a $\Pi ^0_1$ class relative to an enumeration oracle A, which they called a $\Pi ^0_1{\left \langle {A}\right \rangle }$ class. We study the induced extension of the relation B is PA relative (...) to A to enumeration oracles and hence enumeration degrees. We isolate several classes of enumeration degrees based on their behavior with respect to this relation: the PA bounded degrees, the degrees that have a universal class, the low for PA degrees, and the ${\left \langle {\text {self}\kern1pt}\right \rangle }$ -PA degrees. We study the relationship between these classes and other known classes of enumeration degrees. We also investigate a group of classes of enumeration degrees that were introduced by Kalimullin and Puzarenko [14] based on properties that are commonly studied in descriptive set theory. As part of this investigation, we give characterizations of three of their classes in terms of a special sub-collection of relativized $\Pi ^0_1$ classes—the separating classes. These three can then be seen to be direct analogues of three of our classes. We completely determine the relative position of all classes in question. (shrink)

Background The wide proliferation of Covid-19 has impacted billions of people all over the world. This catastrophic pandemic outbreak and ostracism at work have posed challenges for all healthcare professionals, especially for nurses, and have led to a significant increase in the workload, several physical and mental problems, and a change in behavior that is more negative and counterproductive. Therefore, leadership behaviors that are moral in nature serve as a trigger and lessen the adverse workplace effects on nurses’ conduct. Aim (...) this research is directed to explore the impact of post-COVID-19 workplace ostracism on nurses’ counterproductive behavior and examine the role of moral leadership as a mediating factor in post-COVID-19 workplace ostracism and nurses’ counterproductive behavior. Ethical consideration Ethical review and approval Was received from Ethical Committee at the Faculty of Nursing, Alexandria University, Egypt. Methods A cross-sectional and correlation study was implemented in all units of medical, surgical, critical and intensive care units by using three tools; moral leadership questionnaire, Workplace Ostracism Instrument (WOS), and Counterproductive Work Behaviors Questionnaire (CWBs). A convenient sample of 340 from 699 bedside nurses was granted. Results This study revealed that nurses’ perceived moderate mean percent (55.49 ± 3.46) of overall workplace ostracism and counterproductive behavior (74.69 ± 6.15). However, they perceived a low mean percentage of moral leadership. There was a significant positive correlation between workplace ostracism and counterproductive behavior. Otherwise, a significant negative correlation was found between moral leadership, workplace ostracism and counterproductive behavior. Also, this study proved the mediating effect of moral leadership in decreasing workplace ostracism by 79.3% and counterproductive behavior by 36.7%. Conclusion Hospital administrators need to be aware of the significance of moral leadership and apply integrity in the clinical setting to reduce the drawback of isolation on nurses' conduct and increase value for the organization as a whole and nurses in particular.

We report on the first stage of a project on the representations of gender in the coverage of the Arab Spring by Western media. We focus on designing comparable corpora to examine Arab women’s depiction in English and German news during the uprisings. The English corpus is composed of reports published by _The Guardian and The New York Times_. The German corpus consists of articles collected from _Der Spiegel, Die Welt_, _Die Zeit, Frankfurter Allgemeine Zeitung,_ and _Süddeutsche Zeitung_. The datasets (...) were processed through Sketch Engine to identify the terms collocating with _women_ in the English corpus and _Frau_ in the German one. Then, the themes reflected by these expressions in the two corpora were compared. The results show that both news media feature two types of topical frames linked to Arab women; one is associated with the uprisings while the other is related to their recurrent stereotypes in Western news discourse. Yet, there are discrepancies between their focus on related issues to each type. Other differences between the two sets of news outlets include intensity of reporting on Arab women and stressing their nationalities. These findings suggest that although Arab women’s negative stereotypes continued to feature in western news discourse during the Arab Spring, new positive images emerged and contributed to changing their depictions in global media.

Local places, such as communities, cities, and towns, host many cross-cross sector partnerships, many geared primarily toward alleviating local social and environmental issues. Yet, existing literatures focus predominantly on largescale systemic impact and global challenges such as climate change, paying scant attention to the role of local, geographically bounded dynamics in shaping these partnerships. In this article, I conceptualize places as geographic locations imbued with specific meaning systems and material resources to unpack how local embeddedness shape the structure of cross-sector (...) partnerships. Specifically, I investigate how place-based conflict, arising from tensions between the moral and material aspects of a partnership, can shape formalized aspects of organizational structure. These include the scope of operations, partners’ roles, and shared resources. I unpack these relationships using a case study of Occupy Medical, a local partnership between the civic society and the local government in Eugene, Oregon, tackling the problem of providing healthcare to the homeless and other marginalized and disenfranchised communities. The analysis covers the nine-year period of 2011–2020 and spans three major restructurings of the organization, the latest prompted by the onset of the COVID-19 pandemic in March 2020. I theorize two forms of structural arrangements for cross-sector partnerships, confined and leveraged, and further elaborate on the role of cross-sector partnerships in crises response on the local level.

This essay examines Wolfhart Pannenberg’s defense of metaphysics’ foundational importance for philosophy and theology. Among all the modern philosophers whose claims Pannenberg challenges, Martin Heidegger’s discourse against Western metaphysics receives the major portion of criticism. The first thing one concludes from this criticism is an affirmation of a wide intellectual gap that separates Pannenberg’s thought from Heidegger’s, as if each stands at the very opposite corner of the other’s school of thought. The questions this essay tackles are: is this seemingly (...) irreconcilable difference between Pannenberg and Heidegger fully justifiable? What if there is a reading of Panneberg’s and Heidegger’s view of metaphysics that can reveal deeper similarities between the two thinkers than the first reading of Pannenberg’s criticism of Heidegger allows us to see? It then answers these questions by showing that both thinkers actually share a common emphasis on the concepts of ‘time/history’, ‘self-disclosure’ and ‘anticipation’, and their reliance on these notions reveals that Heidegger’s and Pannenberg’s approaches to the phenomenon of understanding and to metaphysical ontology are not fully contradictory but rather hold noticeable hermeneutical similarities.

Intersecting authority-language-and-symbolic power, this article tells the story of a group of continental Francophone African youth who find themselves in an urban French-language high school in southwestern Ontario, Canada. Through their narrative, one is confronted by the trauma of one's own language being declared an illegitimate child, hence becoming a ‘deceptive fluency’ in the ‘eyes of power’ thanks to race and post-coloniality. They are fully consciousness of this situation and their ‘linguistic return’, thus gazing back at the eyes of power (...) and declaring themselves ‘subjects’ capable of love and desire. I briefly address questions of hospitality and language ownership and conclude by addressing the need to re-think the connection between race, power and language. (shrink)

A structure is automatic if its domain, functions, and relations are all regular languages. Using the fact that every automatic structure is decidable, in the literature many decision problems have been solved by giving an automatic presentation of a particular structure. Khoussainov and Nerode asked whether there is some way to tell whether a structure has, or does not have, an automatic presentation. We answer this question by showing that the set of Turing machines that represent automata-presentable structures is ${\rm{\Sigma (...) }}_1^1 $-complete. We also use similar methods to show that there is no reasonable characterisation of the structures with a polynomial-time presentation in the sense of Nerode and Remmel. (shrink)

It is proved that for every countable structure and a computable successor ordinal α there is a countable structure which is ‐least among all countable structures such that is Σ‐definable in the αth jump. We also show that this result does not hold for the limit ordinal. Moreover, we prove that there is no countable structure with the degree spectrum for.

A decade has passed since the breaking out of the ‘Arabic Spring’ revolutionary phenomena all over the Arab World’s societies. Many challenging and radically intriguing developments and ramifications have eventuated out of that era and led the Arab World’s context into unchartered territories of existence and self-understanding. This essay pauses at one of the particular challenges that faces this Sitz im Leben, namely the question of identity-formation and self-perception processes. It argues that the Arab states do manifest in their political (...) and statehood situations a political situation of democracy that is run by ‘non-democrats’. The essay then suggests that this democracy of non-democrats is the outcome of the prevalence of an identity-formation and self-perception rationales that are rooted in crudely religious Weltanschauung that, far from maintaining distinction and particularity individually and communally, turns alterity into a self-otherizing dogma expressive of contrariety and stark divisive and discriminative relatedness to the other. The essay, finally, suggests that liberating the identity-formation process from the dogmatic attempt at turning religion into ‘identity’ per se is the first required step towards a more cross-pollinating and symbiotic relationality between the different persons and groups who live in that context.

ABSTRACTThere is a growing body of literature describing conceptual frameworks for working with participatory visual methods. Through a global health lens, this paper examines some key themes within these frameworks. We reflect on our experiences of working with with an array of PVM to engage community members in Vietnam, Kenya, the Philippines and South Africa in biomedical research and public health. The participants that we have engaged in these processes live in under-resourced areas with high prevalence of communicable and non-communicable (...) diseases. Our paper describes some of the challenges that we have encountered while using PVM to foster knowledge exchange, build relationships and facilitate change among individuals and families, community members, health workers, biomedical scientists and researchers. We consider multiple ethical situations that have arisen through our work and discuss the ways in which we have navigated and negotiated them. We offer our reflections and learning from facil...

Background: Ascertaining the relationship between ethical ideology, moral judgment, and ethical decision among academic nurse educators at work appears to be a challenge particularly in situations when they are faced with a need to solve an ethical problem and make a moral decision. Purpose: This study aims to investigate the relationship between ethical ideology, moral judgment, and ethical decision as perceived by academic nurse educators. Methods: A descriptive correlational research design was conducted at Faculty of Nursing, Alexandria University. All academic (...) nurse educators were included in the study (N = 220). Ethical Position Questionnaire and Questionnaire of Moral Judgment and Ethical Decisions were proved reliable to measure study variables. Ethical considerations: Approval was obtained from Ethics Committee at Faculty of Nursing, Alexandria University. Privacy and confidentiality of data were maintained and assured by obtaining subjects’ informed consent. Findings: This study reveals a significant positive moderate correlation between idealism construct of ethical ideology and moral judgment in terms of recognition of the behavior as an ethical issue and the magnitude of emotional consequences of the ethical situation (p < 0.001; p = 0.031) respectively. Also, there is a positive significant moderate correlation between relativism construct of ethical ideology and overall moral judgment (p = 0.010). Approximately 3.5% of the explained variance of overall moral judgment is predicted by idealism together with relativism. Discussion: The findings suggest that variations in ethical position and ideology are associated with moral judgment and ethical decision. Conclusion: Organizations of academic nursing education should provide a supportive work environment to help their academic staff to develop their self-awareness and knowledge of their ethical position and promoting their ethical ideologies and, in turn, enhance their moral judgment as well as develop ethical reasoning and decision-making capability of nursing students. More emphasis in nursing curricula is needed on ethical concepts for developing nursing competencies. (shrink)

This study examines the topical frames reflected in articles published about Syrian refugees by German, British and American news websites in 2016. We analyze these for terms associated with Syrian refugees and the themes they address then relate them to those we identified for 2015 and to those indicated by German students in expressing their attitudes towards them. The results show that, despite discrepancies in the occurrence of Syrian refugees’ collocates in our 2016 news corpora, they still reflect, at a (...) lower rate, the themes identified for 2015: humanitarianism, conflict, dehumanization, security, economic burden, political responsibility, and integration. The survey results confirm humanitarianism and integration as particularly prominent themes for our participants, too. While our findings provide further discursive evidence for the variation in refugees’ representations in news discourse and for the influence of media on public opinion, they suggest that this impact may be balanced out by other factors including an audience’s critical reading and thinking skills.

This article reports on the first stage of a research project on German university students’ conceptualization of Arab women and to what extent it is affected by the latters’ representation in the Western press during the Arab Spring. We combined discourse analysis and corpus-linguistic approaches to investigate the relationship between lexical items used by the students to express their attitudes toward Arab women and those featuring in news headlines about them published in British, American, and German news media. Results show (...) that the portrayal of Arab women in Western news headlines has a clear impact on German students’ opinions of them. The findings also show that our participants tend to be aware of this effect, which could be partly due to their familiarity with discourse analysis as students of linguistics. These results have implications for incorporating media education systematically in general university courses. (shrink)

Do people hold robots responsible for their actions? While Clark and Fischer present a useful framework for interpreting social robots, we argue that they fail to account for people's willingness to assign responsibility to robots in certain contexts, such as when a robot performs actions not predictable by its user or programmer.

ObjectiveThe scarcity of research on associations between inflammatory markers and symptoms of depression and anxiety during adolescence has yielded inconsistent results. Further, not all studies have controlled for potential confounders. We explored the associations between baseline inflammatory markers and psychological distress including moderators at follow-up in a Norwegian adolescent population sample.MethodsData was derived from 373 girls and 294 boys aged 15–18 years at baseline, in the Fit Futures Study, a large-scale 2-year follow-up study on adolescent health. Baseline data was gathered (...) from 2010 to 2011 and follow-up data from 2012 to 2013. Psychological distress was measured with Hopkins Symptom Checklist. Serum levels of the following inflammatory markers were measured: C-reactive protein, Interleukin 6, Transforming growth factor alpha, Tumor necrosis factor alpha variant 1, and variant 2. Independent associations between baseline inflammatory markers and HSCL-10 at follow-up were explored by linear regressions, in sex-stratified analyses.ResultsIn girls, analyses showed positive associations between all inflammatory markers and HSCL-10, except for TRANCE. However, all associations were non-significant in crude as well as in adjusted analyses. In boys, CRP and TGF-α showed significant associations with HSCL-10, that remained significant after adjustment. Additionally, moderators were found. In boys, CRP was associated with HSCL-10 in those with high body fat and those being physical inactive, and the association between TWEAK and HSCL-10 was dependent upon sleep duration.ConclusionThere were significant prospective associations between CRP, TFG-α, and HSCL-10 in boys aged 15–18 years at baseline.

Timetabling problems are specific types of scheduling problems that deal with assigning certain events to the timeslots. This assigning is subject to certain hard constraints that should be achieved to get a feasible timetable and soft constraints that must meet as many as possible during forming a feasible schedule. This paper introduces an adaptive tabu search. Eleven benchmark datasets of the year 2002 are applied to show the effectiveness of the introduced algorithm. These datasets consist of 5-small, 5-medium, and 1-large (...) dataset. As compared to other methods from previous works, the proposed algorithm produces excellent timetables, in comparison with the algorithms as well as the current results, the mathematical results showed the high effectiveness of the suggested algorithm. It has a minor deficit on the medium or the small problem adaptive Tabu, and the tabu search relies on the tabu list and penalty cost when the change in the penalty cost is checked; if it is still unchanged for the period of iterations (1,000 iterations), the tabu list reduces automatically by (−2); furthermore, the tabu list remains constant.

The investigation of users' satisfactions and intentions in using the services provided by commercial banks needs to be focused on internet banking, since this is the widely used banking service. This paper analyzed the satisfactions and behavioral intentions of Malaysian customers in using Internet Banking, applying the Information System Success Model by the integration of adoption and application technology theory. Some criteria, which were taken into consideration, are as follows: perceived Risk, facilitating Conditions, Price, Performance expectancy, Information Quality, Service Quality, (...) and System Quality. These aspects are important to measure customers' satisfaction and behavior toward Internet and Online Banking. A sample of 362 valid responses, consisting of Malaysian customers who used E-Banking, was used for the purpose of data collection. The relationship between customers' satisfaction and factors influencing their contentment in using Online Banking was investigated. In order to evaluate this, a model called “Structural Equation Model ” was developed and used. Findings showed that most of the Online Banking users were satisfied with the system. Hence, it proves that Online Banking System was generally accepted in the Malaysian community. However, this current research is solely focused on the Malaysian community. Therefore, it may provide the necessary grounds for the study of internet banking accreditation, some useful information for the practitioners, policy makers, and the researchers to improve the system of online banking in Malaysia only. For a future study, a more well-structured research, which can accommodate the global need, would be required. (shrink)

Early adversity and trauma can have profound effects on children’s affective development and mental health outcomes. Interventions that improve mental health and socioemotional development are essential to mitigate these effects. We conducted a pilot study examining whether a reading-based program improves emotion recognition and mental health through socialization in Syrian refugee and Jordanian non-refugee children aged 7–12 years old living in Jordan. To measure emotion recognition, children classified the expression in faces morphed between two emotions, while mental health was assessed (...) using survey measures of optimism, depression, anxiety, distress, and insecurity. Prior to the intervention, both groups of children were significantly biased to interpret ambiguous facial expressions as sad, while there was no clear bias on the fear–anger spectrum. Following the intervention, we found changes in Syrian refugee children’s bias in emotion recognition away from sad facial expressions, although this returned to pre-intervention levels 2 months after the end of the program. This shift in the bias away from sad facial expressions was not associated with changes in self-reported mental health symptoms. These results suggest a potential positive role of the reading intervention on affective development, but further research is required to determine the longer-term impacts of the program. (shrink)

This paper provides a critical review of economic outcome metrics used in healthcare value assessment, emphasizing the evolving landscape of resource allocation, patient-centered approaches, and standardization efforts. With healthcare costs rising globally, the efficient allocation of limited resources is essential. Metrics like Quality-Adjusted Life Years (QALYs), Disability-Adjusted Life Years (DALYs), Incremental Cost-Effectiveness Ratios (ICERs), and Cost-Benefit Analysis (CBA) are central to guiding funding decisions, influencing insurance coverage, and shaping treatment prioritization. Emerging trends, such as the integration of artificial intelligence (AI) (...) and big data, are enhancing the precision of these assessments, while patient-centered metrics underscore the importance of patient satisfaction and quality of life. Additionally, there is a growing push for the standardization of these metrics to create consistent frameworks across diverse health systems. This paper explores case studies, practical applications, and future directions to provide insights into how healthcare systems can adopt more effective, globally aligned economic assessments.
