The idea that “simplicity is a sign of truth”, and the related “Occam’s razor” principle, stating that, all other things being equal, simpler models should be preferred to more complex ones, have been long discussed in philosophy and science. We explore these ideas in the context of supervised machine learning, namely the branch of artificial intelligence that studies algorithms which balance simplicity and accuracy in order to effectively learn about the features of the underlying domain. Focusing on statistical learning theory, (...) we show that situations exist for which a preference for simpler models provably slows down, instead of favoring, the supervised learning process. Our results shed new light on the relations between simplicity and truth approximation, which are briefly discussed in the context of both machine learning and the philosophy of science. (shrink)

Combining the liberalism of Locke and the "civic humanism" of Republicanism, Mary Wollstonecraft explored the need of women for coed and equal education with men, economic independence whether married or not, and representation as citizens in the halls of government. In doing so, she foreshadowed and surpassed her much better known successor, John Stuart Mill. Ten feminist scholars prominent in the fields of political philosophy, constitutional and international law, rhetoric, literature, and psychology argue here that Wollstonecraft, by reason of the (...) scope and complexity of her thought, belongs in the "canon" of political philosophers along with Rousseau and Burke, her contemporaries, both of whom she strenuously engaged in political debate. These essays explore the many aspects of her thought that resound so tellingly to the modern woman, including her groundbreaking attempt to be completely self-sufficient. The final bibliographical essay outlines the changing interpretations of Wollstonecraft's work over the past two hundred years and evaluates her standing among political theorists today. Contributors are Maria J. Falco, Penny A. Weiss, Virginia Sapiro, Virginia L. Muller, Wendy Gunther-Canada, Carol H. Poston, Miriam Brody, Moira Ferguson, Louise Byer Miller, and Dorothy McBride Stetson. (shrink)

Diplomat, bureaucrat, and practical politician, Niccolò Machiavelli served as Second Secretary to the Republic of Florence in the early sixteenth century and became the first major political thinker in the western tradition to make a complete break with the Aristotelian model of politics as a branch of ethics. While _The Prince _is his most famous work, grounding his reputation as the progenitor of "Realpolitik," his many other writings have contributed to a more complex and broader image of the man and (...) his political thought. Thus in recent years Machiavelli has come to be seen as a republican and a proto-liberal by some mainstream political theorists, and as an obfuscator of traditional values and ideologies, including gender roles, by feminists and non-feminists alike. The contributors to this volume, grappling with questions about the position of women in political society, investigate whether or not Machiavelli was truly a misogynist and a proto-fascist or instead a proto-feminist and a democratic republican. Among the themes they explore are the implications of such dichotomies as _Fortuna_ and _virtù_, the public and the private, nature and reason, ends and means, functionality and the common good, as well as the importance of the military to the socialization of citizens, particularly women, to civic life, and the social construction of gender. Some of the contributors even consider the possibility that Machiavelli's approach to ethics provides a special insight that feminists, and women generally, might explore to their benefit. Besides the editor, the contributors are Wendy Brown, Jane Jaquette, Donald McIntosh, Melissa Matthes, Vesna Marcina, Martin Morris, Cary Nederman, Andrea Nicki, Mary O'Brien, Hanna Pitkin, Arlene Saxonhouse, John Shin, R. Claire Snyder, and Catherine Zuckert. (shrink)

The four theistic proofs of Monologion are based on the categories of being per se and being per aliud. This article analyses them through a comparative approach. The categories of per se and per aliud are compared with the categories of substance (ti) and function (yong) as touched on the first chapter of the Rectifying Ignorance (正蒙 Zhengmeng) of Zhang Zai (1020–1077), an exponent of neo-Confucianism. In fact, the two pairs of categories explain the relationship between an absolute, the supreme (...) nature (summum) or the Great Void (太虚 taixu) and the sensible world. Through the comparison, this article highlights the fundamental function of being per aliud in the rational knowledge of the supreme nature that exists per se and provides new insights into the process of derivation of being per aliud from the being per se.Contribution: This article, through the comparison with the Chinese philosophical tradition, intends to offer a new perspective on the understanding of the Anselmian categories of being per se and being per aliud.

​Authors, Factions, and Courts in Angevin England: A Literature of Personal Ambition (12th-13th Century) advances a model for historical study of courtly literature by foregrounding the personal aims, networks, and careers as the impetus for much of the period’s literature. The book takes two authors as case studies – Gerald of Wales and Walter Map – to show how authors not only built their own stories but also used popular narratives and the tools of propaganda to achieve their own, personal (...) goals. The purpose of this study is to overturn the top-down model of political patronage, in which patrons – and particularly royal patrons – set the cultural agenda and dictate literary tastes. Rather, Fabrizio De Falco argues that authors were often representative of many different interests expressed by local groups. To pursue those interests, they targeted specific political factions in the changeable political scenario of Angevin England. Their texts reveal a polycentric view of cultural production and its reception. The study aims to model a heuristic process which is applicable to other courtly texts besides the chosen case-studies.

Ethical conflicts are arising as a result of the growing complexity of clinical care, coupled with technological advances. Most studies that have developed instruments for measuring ethical conflict base their measures on the variables ‘frequency’ and ‘degree of conflict’. In our view, however, these variables are insufficient for explaining the root of ethical conflicts. Consequently, the present study formulates a conceptual model that also includes the variable ‘exposure to conflict’, as well as considering six ‘types of ethical conflict’. An instrument (...) was then designed to measure the ethical conflicts experienced by nurses who work with critical care patients. The paper describes the development process and validation of this instrument, the Ethical Conflict in Nursing Questionnaire Critical Care Version (ECNQ-CCV). (shrink)

Critical thinking is a complex, dynamic process formed by attitudes and strategic skills, with the aim of achieving a specific goal or objective. The attitudes, including the critical thinking attitudes, constitute an important part of the idea of good care, of the good professional. It could be said that they become a virtue of the nursing profession. In this context, the ethics of virtue is a theoretical framework that becomes essential for analyse the critical thinking concept in nursing care and (...) nursing science. Because the ethics of virtue consider how cultivating virtues are necessary to understand and justify the decisions and guide the actions. Based on selective analysis of the descriptive and empirical literature that addresses conceptual review of critical thinking, we conducted an analysis of this topic in the settings of clinical practice, training and research from the virtue ethical framework. Following JBI critical appraisal checklist for text and opinion papers, we argue the need for critical thinking as an essential element for true excellence in care and that it should be encouraged among professionals. The importance of developing critical thinking skills in education is well substantiated; however, greater efforts are required to implement educational strategies directed at developing critical thinking in students and professionals undergoing training, along with measures that demonstrate their success. Lastly, we show that critical thinking constitutes a fundamental component in the research process, and can improve research competencies in nursing. We conclude that future research and actions must go further in the search for new evidence and open new horizons, to ensure a positive effect on clinical practice, patient health, student education and the growth of nursing science.

Objectives: Investigate and identify the relationship between physical exercise and cognitive performance measured by using different cognitive tests taken from Cambridge Brain Science.Methods: Thirty subjects, divided into two groups, undergo twelve cognitive tests from CBS. A comparison between the pre- and post-exercise results in terms of cognitive performance differences is carried out. Regression analysis between Heart Rate Variability features and CBS tests results is performed.Results: In most CBS tests, there is an improvement, or at least a confirmation, of the subject's (...) cognitive ability, for both groups. Reasoning, concentration, and planning tests seem to undergo critical positive changes. The regression analysis, performed by using a set of different algorithms, has demonstrated that it is possible, by monitoring the HRV during the exercise, to predict to some extent the cognitive performance, i.e., the CBS tests results. The best performing regression algorithms are Simple Linear and REPTree. The statistical analysis has proved that physical activity is statistically useful for the subjects in improving their cognitive performance.Conclusions: This study has numerically appraised the improvement, the conservation, or the worsening on different aspects of cognition. The found mathematical relationship between physical exercise and cognitive performance suggests that it is possible to predict the beneficial effect of various exercises on executive and attentive control.

BackgroundImplementing the routine consultation of patient advance directives in hospital emergency departments and emergency medical services has become essential, given that advance directives constitute the frame of reference for care personalisation and respect for patients’ values and preferences related to healthcare. The aim of this study was to assess the levels and relationship of knowledge and attitudes of nursing and medical professionals towards advance directives in hospital emergency departments and emergency medical services, and to determine the correlated and predictor variables (...) of favourable attitudes towards advance directives.MethodsObservational, descriptive, and cross-sectional study. The study was conducted in the emergency department of a second-level hospital and in the emergency medical service. Data collection was performed from January 2019 to February 2020. The STROBE guidelines were followed for the preparation of the study.ResultsA total of 173 healthcare professionals responded to the questionnaire. Among them, 91.3% considered that they were not sufficiently informed about advance directives, and 74% acknowledged not having incorporated them into their usual practice. Multinomial analysis indicated a statistically significant relationship between the variable emergency medical service and having more favourable attitudes towards consulting the advance directives in their practical application (OR 2.49 [95% CI 1.06–5.88]; p = 0.037) and compliance in complex scenarios (OR 3.65 [95% CI 1.58 − 8.41]; p = 0.002). Working the afternoon and night shift was a predictor variable for obtaining a higher score with respect to attitudes in complex scenarios.ConclusionThere is an association between the level of knowledge that nursing and medical professionals have about advance directives and the scores obtained on the attitude scales at the time of practical implementation and in complex scenarios. This shows that the more knowledge professionals have, the more likely they are to consult patients' advance directives and to respect their wishes and preferences for care and/or treatment.

This essay introduces the term arbitrary cause as a precise description of the contingent structural relationship of figurative language to social reality. At the present time our critical vocabulary lacks a term that characterizes that relationship. The aim of the present essay is to establish the importance of the notion of arbitrary cause in understanding the process of figurative representation. The essay examines Saussurean linguistics, structuralist and poststructuralist revisions of Saussure, and provides a detailed set of examples demonstrating the instability (...) of the concept of the arbitrary in common usage. The essay concludes with a discussion of literary expression. (shrink)

Drawing on the work of Max Weber, Edward Shils, Charles Camic and Thomas Spence Smith, among others, this article analyzes the effect of the breakdown of charismatic groups on tragic protagonists. Because criticism has usually focused on the isolation of tragic figures, little attention has been paid to group formation and group dissolution as significant components of tragedy. Yet group function makes a manifest contribution to tragic denouement: the vicissitudes of charismatic authority not only reflect but often bring about the (...) catastrophes in tragic drama. The article demonstrates this thesis in a concluding discussion of Shakespeare's Othello. (shrink)

Recent studies indicate that mammalian chromosomes contain discretecis‐acting loci that control replication timing, mitotic condensation, and stability of entire chromosomes. Disruption of the large non‐coding RNA gene ASAR6 results in late replication, an under‐condensed appearance during mitosis, and structural instability of human chromosome 6. Similarly, disruption of the mouse Xist gene in adult somatic cells results in a late replication and instability phenotype on the X chromosome. ASAR6 shares many characteristics with Xist, including random mono‐allelic expression and asynchronous replication timing. (...) Additional “chromosome engineering” studies indicate that certain chromosome rearrangements affecting many different chromosomes display this abnormal replication and instability phenotype. These observations suggest that all mammalian chromosomes contain “inactivation/stability centers” that control proper replication, condensation, and stability of individual chromosomes. Therefore, mammalian chromosomes contain four types ofcis‐acting elements, origins, telomeres, centromeres, and “inactivation/stability centers”, all functioning to ensure proper replication, condensation, segregation, and stability of individual chromosomes.

We introduce the new notion of additive “multibox” for linear logic proof-nets. Thanks to this notion, we define a cut-elimination procedure which associates with every proof-net of multiplicative and additive linear logic a unique cut-free one.

Vaesen infers unique properties of mind from the appearance of specific cultural innovation – a correlation without causal direction. Shifts in habitat, population density, and group dynamics are the only independently verifiable incentives for changes in cultural practices. The transition from Acheulean to Late Stone Age technologies requires that we consider how population and social dynamics affect cultural innovation and mental function.

Los principales patógenos víricos que podemos ad­quirir ingiriendo alimentos contaminados son los norovirus, el virus de la hepatitis A y el virus de la hepatitis E que se propagan principalmente a través de la vía fecal oral. En los últimos años, la incidencia de brotes de transmisión alimentaria causados por estos patógenos ha experimentado un aumento considerable, en parte debido al comercio globalizado y a los cambios en los hábitos de consumo. Las matrices alimentarias que mayor riesgo representan para el (...) consumidor son los moluscos bivalvos, ve­getales de IV gama, frutas tipo baya y platos listos para comer. Actualmente las técnicas moleculares son las más habituales para la detección de estos patógenos en alimentos, aunque toda­vía existen dudas acerca del significado de la presencia de estos genomas víricos en términos de seguridad alimentaria. La infec­tividad de estos patógenos en alimentos viene también determi­nada por su elevada persistencia ambiental y por su resistencia a los tratamientos aplicados para la conservación de los alimentos.

Hilde Lindemann argues that personhood is the shared practice of recognizing and responding to one another. She calls this practice holding. Holding, however, can fail. Holding failure, by stereotyping for example, can inhibit others’ epistemic confidence and ability to recall true beliefs as well as create an environment of racism or sexism. How might we avoid holding failure? Holding failure, I argue, has many epistemic dimensions, so I argue that moral encroachment has the theoretical tools available to avoid holding failures. (...) The goal of this paper, therefore, is to articulate and understand the epistemology of holding in an attempt to remedy holding failure. I show that the virtue of wokeness emerges from an epistemic environment tainted with moral encroachment. I argue that as long as an individual is woke, she will have a tendency to avoid holding failures. Wokeness and moral encroachment, consequently, are fundamental to the epistemology of holding and consistent proper holding. (shrink)

The aim of this paper is to investigate among a group of non-profit organizations: a) the effect of ethical leadership on volunteers’ satisfaction, affective organizational commitment and intention to stay in the same organization; b) the role played by job satisfaction as a mediator in the relationship between ethical leadership and volunteers’ intentions to stay in the same organization, as well as between ethical leadership and affective commitment. An anonymous questionnaire was individually administered to 198 Italian volunteers of different non-profit (...) organizations. The questionnaire contained the Ethical Leadership Scale, the Volunteers Satisfaction Index, the Affective organization Scale, as well as questions regarding the participants’ age, sex, type of work, level of education, length of their volunteer works, intention to volunteer in the following months in the same organization. The construct as well the effects of EL on volunteers is approached in light of the Social Exchange Theory and the Social Learning Theory. Structural equation models were used to test hypothesized relationships. The results confirm the role of mediation of volunteer satisfaction in the relationships between the variables studied. In particular, ethical leadership was found to be positively associated both with volunteers’ intention of staying and with their affective commitment. In the first case this relationship is fully explained by the mediation of the volunteers’ satisfaction, while the latter is explained by both direct and indirect factors. To the authors’ knowledge, this the first attempt to understand the role played by ethical leadership on volunteers’ behavior and, more in general, in the management of non-profit organizations. Findings are relevant both for practitioners and managers of non-profit organization, since they suggest the relevance of the perception of ethical leadership by volunteers, as well as for scholars, since they further deepen the knowledge on EL and its effects on the followers. Limits of the study: the questionnaire was administered only among a group of non-statistical sample of volunteers. Furthermore, the study reached only volunteers from Italian non-profit organization. (shrink)

Much of the climate ethics discussion centers on considerations of compensatory justice and historical accountability. However, little attention is given to supporting and defending the Beneficiary Pays Principle as a guide for policymaking. This principle states that those who have benefitted from an instance of harm have an obligation to compensate those who have been harmed. Thus, this principle implies that those benefitted by industrialization and carbon emission owe compensation to those who have been harmed by climate change. Beneficiary Pays (...) is commonly juxtaposed with Polluter Pays Principle and the Ability to Pay Principle in the relevant literature. Beneficiary Pays withstands objections that raise suspicion for the latter two. (shrink)
