Background:Nurses and nursing students appear vulnerable to moral distress when faced with ethical dilemmas or decision-making in clinical practice. As a result, they may experience professional dissatisfaction and their relationships with patients, families, and colleagues may be compromised. The impact of moral distress may manifest as anger, feelings of guilt and frustration, a desire to give up the profession, loss of self-esteem, depression, and anxiety.Objectives:The purpose of this review was to describe how dilemmas and environmental, relational, and organizational factors contribute (...) to moral distress in undergraduate student nurses during their clinical experience and professional education.Research design:The research design was a systematic literature review.Method:The search produced a total of 157 articles published between 2004 and 2014. These were screened with the assessment sheet designed by Hawker and colleagues. Four articles matched the search criteria (one quantitative study and three qualitative), and these were separately read and analyzed by the researchers. The process of review and analysis of the data was supervised by a colleague experienced in moral distress who provided an independent quality check.Ethical consideration:Since this was a systematic review, no ethical approval was required.Findings:From the analysis, it emerged that inequalities and healthcare disparities, the relationship with the mentor, and students’ individual characteristics can all impact negatively on the decisions taken and the nursing care provided, generating moral distress. All these factors condition both the clinical experience and learning process, in addition to the professional development and the possible care choices of future nurses.Conclusion:Few studies dealt with moral distress in the setting of nurse education, and there is a knowledge gap related to this phenomenon. The results of this review underline the need for further research regarding interventions that can minimize moral distress in undergraduate nursing students. (shrink)

The time marked by the clock hands, the so-called “objective time,” is deeply different from the one perceived by the individual. Starting from this hypothesis, directly connected to the subjective modality of “living” the time and defined as time perspective, we will try to understand how much it affects the various domains of people's lives, attitudes, and experiences. Therefore, the research investigates whether all our decisions can be influenced by one or more time perspectives beyond our awareness. Last, but not (...) least, we will try to understand if some time perspectives in specific contexts are more functional and adaptive than others. (shrink)

Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

In recent years, scholars have sought to investigate the impact that ethical leaders can have within organisations. Yet, only a few theoretical perspectives have been adopted to explain how ethical leaders influence subordinate outcomes. This study therefore draws on social rules theory (SRT) to extend our understanding of the mechanisms linking ethical leadership to employee attitudes. We argue that ethical leaders reduce disengagement, which in turn promotes higher levels of job satisfaction and organisational commitment, as well as lower turnover intentions. (...) Co-worker social undermining is examined as a moderator of the relationship between ethical leadership and disengagement, as we suggest that it is difficult for ethical leaders to be effective when co-worker undermining prevails. To test the proposed model, questionnaires were administered to 460 nurses in Romanian hospital settings over three time points separated by two-week intervals and the hypotheses were tested using generalised multilevel structural equation modeling (GSEM) with STATA. The findings revealed that ethical leadership has a beneficial effect on employee attitudes by reducing disengagement. However, the relationship between ethical leadership and disengagement was moderated by co-worker social undermining, such that when undermining was higher, the significance of the mediated relationships disappeared. These results suggest that while ethical leaders can promote positive employee attitudes, their effectiveness is reduced in situations where co-worker undermining exists. (shrink)

Objective: Quality of Life is an important predictor of patient's recovery and survival in lung cancer patients. The aim of the present study is to identify 1-year trends of lung cancer patients' QoL after robot-assisted or traditional lobectomy and investigate whether clinical and sociodemographic variables may predict these trends.Methods: An Italian sample of 176 lung cancer patients undergoing lobectomy completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire—Core 30 at the pre-hospitalization, 30 days, 4 months, (...) 8 months, and 12 months after surgery. Sociodemographic and clinical characteristics were also collected. The individual change over time of the 15 dimensions of the EORTC QLQ-C30 and the effects of pre-surgery scores of QoL dimensions, type of surgery, perioperative complications, and age on patients' QoL after surgery were studied with the individual growth curve models.Results: Patients had a good recovery after lobectomy: functioning subscales improved over time, while most of the symptoms became less severe over the care process. Perioperative complications, type of surgery, pre-surgery status, and age significantly affected these trends, thus becoming predictors of patients' QoL.Conclusion: This study highlights different 1-year trends of lung cancer patients' QoL. The measurement of pre- and post-surgery QoL and its clinical and sociodemographic covariables would be necessary to better investigate patients' care process and implement personalized medicine in lung cancer hospital divisions.

Background Record linkage is a useful tool for health research. Potential benefits aside, its use raises discussions on privacy issues, such as whether a written informed consent for access to health records and linkage should be obtained. The authors aim to systematically review studies that assess consent proportions to record linkage. Methods 8 databases were searched up to June 2011 to find articles which presented consent proportions to record linkage. The screening, eligibility and inclusion of articles were conducted by two (...) independent reviewers. The authors carried out meta-regression, subgroup and sensitivity analyses to assess heterogeneity. Results Of the 141 studies identified, only 11 presented empirical consent proportions and were included in the systematic review. The consent proportion varied widely from 39% to 97%. Seven studies presented consent proportions of 88% or higher, one of 72%, and only three presented consented proportion equal to or lower than 53%. None of the studies' characteristics evaluated explained heterogeneity. Conclusion The results of this review show that, in general, individuals tend to consent to the use of their data for record linkage, with exceptions in specific populations or minorities. The authors believe that this, as well as the cited literature, lends support to policies that, while keeping relevant ethical controls in place, do not require individual informed consent for each and every study that relies on secondary data.

Knowledge brokers are among the main channels of communication between scientists and the public and a key element to establishing a relation of trust between the two. But translating knowledge from the scientific community to a wider audience presents several difficulties, which can be accentuated in times of crisis. In this paper we study some of the problems that knowledge brokers face when communicating in times of crisis. During the first wave of the COVID-19 pandemic, we collected interviews with Italian (...) experts that played a major role as knowledge brokers in the local media. We asked them questions about five main topics: the features and role of science communicators; the use of language in communicating science; the importance of the relation of trust with the public; the peculiarity of communicating in a context of emergency; the problem of disagreement among experts, and its public perception and communication. The goal of this paper is to understand, through the words of knowledge brokers themselves, what they consider as best practices (and obstacles) to create trust between scientists and the public. Our empirical work can inform normative accounts of what knowledge brokering should be about. (shrink)

O presente artigo trata da relação entre teoria e prática no pensamento de Theodor W. Adorno com o objetivo de analisar as possibilidades de emancipação do sujeito no âmbito da sociedade capitalista contemporânea, questionando sobre um suposto pessimismo do autor. Para tanto, serão contextualizadas as relações entre sujeito e objeto, natureza e razão, teoria e prática e formação e semiformação, com a finalidade de pensar a importância fundamental da teoria para a transformação do mundo a partir de uma análise crítica (...) da sociedade, bem como a pertinência dessa análise ao atual momento brasileiro. A transformação do mundo será pensada a partir das possibilidades de emancipação do sujeito e o papel da formação humana nesse processo no interior de um modelo educacional cada vez mais determinados pelos interesses do capital que direcionam a educação a aspectos meramente práticos de adaptação ao mercado de trabalho. A conclusão aponta no sentido da necessidade imperativa da manutenção da formação teórica e crítica diante dos constrangimentos de ordem prática de um mundo administrado pelos valores capitalistas. Palavras-chave: Theodor W. Adorno. Relação teoria e prática. Semiformação. Pessimismo teórico. Critical Theory and Educational Practice: On the relationship between theoretical pessimism and the transformation of the world to T.W. Adorno Abstract: This article deals with the relationship between theory and practice in the thought of Theodor W. Adorno with the aim of analyzing the possibilities of the subject's emancipation in the context of contemporary capitalist society, questioning the author's supposed pessimism. Therefore, the relationships between subject and object, nature and reason, theory and practice, and Bildung and Halbbildung will be contextualized, with the purpose of thinking about the fundamental importance of theory for the transformation of the world from a thought marked by a critical analysis of the society, as well as the relevance of this analysis to the current Brazilian moment. The transformation of the world will be thought from the possibilities of emancipation of the subject and the role of human formation in this process within an educational model increasingly determined by the interests of capital that led education to merely practical aspects of adaptation to the labor market. The conclusion points towards the imperative need to maintain theoretical and critical education in the face of practical constraints in a world managed by capitalist values. Key-words: Theodor W. Adorno. Theory and practice relationship. Semi-formation. Theoretical pessimism. Teoría, Crítica y Práctica Educativa: Sobre La Relación Entre Pesimismo Teórico Y Transformación Del Mundo En T.W.

The concept of Smart Healthy Age-Friendly Environments (SHAFE) emphasises the comprehensive person-centred experience as essential to promoting living environments. SHAFE takes an interdisciplinary approach, conceptualising complete and multidisciplinary solutions for an inclusive society. From this approach, we promote participation, health, and well-being experiences by finding the best possible combinations of social, physical, and digital solutions in the community. This initiative emerged bottom-up in Europe from the dream and conviction that innovation can improve health equity, foster caring communities, and sustainable development. (...) Smart, adaptable, and inclusive solutions can promote and support independence and autonomy throughout the lifespan, regardless of age, gender, disabilities, cultural differences, and personal choices, as well as promote happier and fairer living places. The New European Bauhaus initiative gathers “beautiful, sustainable, and inclusive projects and ideas” to inspire a positive transformation around us. The New European Bauhaus 2024 Festival took place between 9-13 April. “Designing the perfect New European Bauhaus neighbourhood: New European Bauhaus meets SHAFE” was a Satellite Event of the Festival, held as an online workshop, organised by the SHAFE Foundation on April 9th, 2024. At the event, a group of 50 participants with a multidisciplinary background discussed how to meet the challenges of the European Garcia family to enable them to live in a perfect neighbourhood. The White Paper presents the findings of the participants with the New European Bauhaus inspiring projects and ideas to house the European Garcia family in their neighbourhood. The White Paper recommends developers, designers, planners, and policymakers to include person-centred design of social and physical environments and technologies. Although awareness of person-centred design is growing, many initiatives still hamper the inclusion of citizens or end-users throughout the development of products and services. (shrink)

Introduction Good quality of care is dependent on nurses’ strong clinical skills and moral competencies, as well. While most nurses work with high moral standards, the moral performance of some nurses in some organizations shows a deterioration in their moral sensitivity and actions. The study reported in this paper aimed to explore the experiences of nurses regarding negative changes in their moral practice. Materials and methods This was a qualitative study utilizing an inductive thematic analysis approach, which was conducted from (...) February 2017 to September 2019. Twenty-five nurses participated in semi-structured interviews. Results The main theme that emerged from our analysis was one of moral neutralization in the context of an unethical moral climate. We found five sub-themes, including: feeling discouraged; normalization; giving up; becoming a justifier; and moral indifference. Conclusions Unethical moral climates in health organizations can result in deterioration of morality in nurses which can harm both patients and health systems. Some unethical behaviors in nurses can be explained by this process. (shrink)

In this chapter, we offer a reconstruction of the evolution of Leibniz’s thought concerning the problem of the infinite divisibility of bodies, the tension between actuality, unassignability, and syncategorematicity, and the closely related question of the possibility of infinitesimal quantities, both in physics and in mathematics.Some scholars have argued that syncategorematicity is a mature acquisition, to which Leibniz resorts to solve the question of his infinitesimals – namely the idea that infinitesimals are just signs for Archimedean exhaustions, and their unassignability (...) is a nominalist maneuver. On the contrary, we show that syncategorematicity, as a traditional idea of classical scholasticism, is a feature of young Leibniz’s thinking, from which he moves away in order to solve the same problem, as he gains mathematical knowledge.We have divided Leibniz’s path toward his mature view of infinitesimals into five phases, which are especially significant for reconstructing the entire evolution. In our reconstruction, an important role is played by Leibniz’s text De Quadratura Arithmetica. Based on this and other texts, we dispute the thesis that fictionality coincides with syncategorematicity, and that unassignability can be bypassed. (In this chapter, we employ “syncategorematic” as a shorthand for “eventually identifiable with a procedure of exhaustion” and, as a consequence, “involving only assignable quantities.” We also identify syncategorematicity with potentiality, as suggested by some part of the scholastics, and in Sect. 2.2, we show that the two characterizations are equivalent, provided that “potentiality” is intended in the correct way: namely as in the unending iterative procedures of Greek mathematics.) On the contrary, we maintain that unassignability, as incompatible with the principle of harmony, is the ultimate reason for the fictionality of infinitesimals. (shrink)

RESUMOO presente artigo tem como objetivo analisar os meandros da composição e suas intertextualidades na polêmica do samba entre Noel Rosa e Wilson Batista, observando o dialogismo na interação verbal e musical entre os autores e os diversos textos da década de 1930. Ao apurar os ouvidos sobre a "polêmica do samba" observa-se que as composições revelam tensões inexoráveis entre um mundo festivo do "malandro" e os limites da realidade da época. Desse modo, com suporte em estudos que tratam deste (...) tema, busca-se trazer à tona um insight sobre este "duelo" musical que está, certamente, muito mais disseminado na sociedade que restrito a questões puramente estéticas.ABSTRACTThe purpose of this paper is to analyze the meanders of composition and their intertextuality in the samba controversy between Noel Rosa and Wilson Batista. We observe dialogism in the verbal and musical interaction between the samba writers and several texts of the 1930s. When ears are in tune with the "samba controversy," one observes that the compositions reveal inexorable tensions between the festive world of the "malandro" and the limits of the reality of the time. Accordingly, based on studies that address this theme, we aim to present an insight into this musical "duel," which is not restricted to purely aesthetics issues, but certainly disseminated in society.

Trafficking in persons is a multi-sided phenomenon accompanying the current migration flows, therefore, the actions that must be undertaken in order to prevent, combat the phenomenon as well as to assist the victims of trafficking require a large partnership between all the actors involved: international organisations, governmental institutions and representatives of civil society. The special psychological, ethical issues raised especially by trafficking prevention and assistance to victims make the church and various religious organisations play a very important role in the (...) corresponding networks at both international and national level. Even if the integration of the church in the networks fighting against trafficking in persons has been quite largely addressed worldwide, there are but few studies undertaken in Romania in this area. Our paper opens the room for dialogue among the researchers interested in this topic from an interdisciplinary perspective to discuss the possibilities to establish sustainable partnerships between the state and the church against rafficking in persons. With this aim in view, we have first carried out a quantitative analysis of the scope and dynamics of trafficking in persons in Romania focusing on the victims’ profile by exploitation type. The main socio-demographic characteristics (gender, age, schooling, area of origin) have been considered in order to identify the vulnerability factors related to the risk involved by trafficking, both at national and regional level. We have also examined the responses in legislative and institutional terms, with a special emphasis on the collaboration between the state and the church in preventing and combating trafficking in persons. Of special relevance are the conclusions resulted from the field research undertaken in the area covered by the Diocese of Maramures and Satu Mare. (shrink)

The results in this paper are in a context of abstract elementary classes identified by Shelah and Villaveces in which the amalgamation property is not assumed. The long-term goal is to solve Shelah’s Categoricity Conjecture in this context. Here we tackle a problem of Shelah and Villaveces by proving that in their context, the uniqueness of limit models follows from categoricity under the assumption that the subclass of amalgamation bases is closed under unions of bounded, -increasing chains.

In the paper “Categoricity in abstract elementary classes with no maximal models”, we address gaps in Saharon Shelah and Andrés Villavecesʼ proof in [4] of the uniqueness of limit models of cardinality μ in λ-categorical abstract elementary classes with no maximal models, where λ is some cardinal larger than μ. Both [4] and [5] employ set theoretic assumptions, namely GCH and Φμ+μ+).Recently, Tapani Hyttinen pointed out a problem in an early draft of [3] to Villaveces. This problem stems from the (...) proof in Shelah and Villavecesʼ [4] that reduced towers are continuous. Residues of this problem also infect the proof of Proposition II.7.2 in VanDieren [5]. We respond to the issues in Shelah and Villaveces [4] and VanDieren [5] with alternative proofs under the strengthened assumption that the abstract elementary class is categorical in μ+. (shrink)

Blockchain is an open digital ledger technology that has the capability of significantly altering the way that people operations operate in organizations. This research takes a first step in proposing several ways in which the blockchain technology can be used to improve current organizational practices, while also considering the ethical implications. Specifically, the paper examines the role that blockchain technology plays in three primary areas of people operations: entry to the organization, intraorganizational processes, and exit. In each section, the paper (...) reviews the ethical implications from the lenses of virtue ethics, utilitarianism, deontology and contractarianism. The paper concludes that in whole the implementation of blockchain technology in people operations processes can create a more ethical work environment. However, careful implementation is necessary and requires extensive examination of ethical implications in advance. (shrink)

As a neonatal neurologist, I serve families facing tragic decisions in which they must balance trade-offs between death and life with profound disability. I often find myself in complex discussions about future outcome, in which families sort through in real-time what information they value most in making such a choice. Will he laugh? Will he be in pain? Will he know how much he’s loved? In this month’s feature article, Brick et al share the results of an online survey aimed (...) at assessing public views on when a life is not worth living, in an effort to inform ongoing legal and clinical debates about withdrawal of life-sustaining treatment for children. These findings raise important questions about how we define and measure outcomes that matter to parents as they make these tragic decisions. It is challenging to interpret these findings in the absence of context of how decision-making for infants occurs in real-time. The nature of this study and its objective required that cases be substantially simplified. As the authors acknowledge, the prognoses and function of the children involved in these cases were often deeply contested. Prognostic uncertainty is common for children with significant …. (shrink)

Traditionally, what we are conscious of in self-consciousness is something non-corporeal. But anti-Cartesian philosophers argue that the self is as much corporeal as it is mental. Because we have the sense of proprioception, a kind of body awareness, we are immediately aware of ourselves as bodies in physical space. In this debate the case histories of patients who have lost their sense of proprioception are clearly relevant. These patients do retain an awareness of themselves as corporeal beings, although they hardly (...) feel their bodies. They can initiate movements, and with the help of visual feedback learn to control them. It is shown that the traditional view of the self as immaterial is not supported by these cases. But the argument against this view has to be amended. It relies too much on bodily sensations, and misses the importance of active self-movement. (shrink)

Significant scientific and technological advances in intensive care have been made. However, patients in the intensive care unit may experience discomfort, loss of control, and surreal experiences. This has generated relevant debates about how to humanize the intensive care units and whether humanization is necessary at all. This paper aimed to explore how humanizing intensive care is described in the literature. A scoping review was performed. Studies published between 01.01.1999 and 02.03.2020 were identified in the CINAHL, Embase, PubMed, and Scopus (...) databases. After removing 185 duplicates, 363 papers were screened by title and abstract. Full-text screening of 116 papers led to the inclusion of 68 papers in the review based on the inclusion criteria; these papers mentioned humanizing or dehumanizing intensive care in the title or abstract. Humanizing care was defined as holistic care, as a general attitude of professionals toward patients and relatives and an organizational ideal encompassing all subjects of the healthcare system. Technology was considered an integral component of intensive care that must be balanced with caring for the patient as a whole and autonomous person. This holistic view of patients and relatives could ameliorate the negative effects of technology. There were geographical differences and the large number of studies from Spain and Brazil reflect the growing interest in humanizing intensive care in these particular countries. In conclusion, a more holistic approach with a greater emphasis on the individual patient, relatives, and social context is the foundation for humanizing intensive care, as reflected in the attitudes of nurses and other healthcare professionals. Demands for mastering technology may dominate nurses’ attention toward patients and relatives; therefore, humanized intensive care requires a holistic attitude from health professionals and organizations toward patients and relatives. Healthcare organizations, society, and regulatory frameworks demanding humanized intensive care may enforce humanized intensive care. (shrink)

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible . Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning and reproducing . This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable (...) innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation. (shrink)

Given that mitigating climate change is a large-scale global issue, what obligations do individuals have to lower their personal carbon emissions? I survey recent suggestions by Walter Sinnott-Armstrong and Dale Jamieson and offer models for thinking about their respective approaches. I then present a third model based on the notion of structural violence. While the three models are not mutually incompatible, each one suggests a different focus for mitigating climate change. In the end, I agree with Sinnott-Armstrong that people have (...) limited moral obligations to directly lower personal emissions, but I offer different reasons for this conclusion, namely that the structural arrangements of our lives place a limit on how much individuals can restrict their own emissions. Thus, individuals should focus their efforts on changing the systems instead (e.g., the design of cities, laws and regulation, etc.), which will lead to lower emissions on a larger scale. (shrink)

Mass-marketing frauds are on the increase. Given the amount of monies lost and the psychological impact of MMFs there is an urgent need to develop new and effective methods to prevent more of these crimes. This paper reports the early planning of automated methods our interdisciplinary team are developing to prevent and detect MMF. Importantly, the paper presents the ethical and social constraints involved in such a model and suggests concerns others might also consider when developing automated systems.
