Abstract“The Book of Secrets in the Results of Ideas”, usually called “The Book of Secrets” is a codex containing drawings and descriptions of thirty-one artifacts attributed to the engineer Alī Ibn Khalaf al-Murādī, who lived in Andalusia in southern Spain at the beginning of the 11th century. This manuscript is one of the first written testimonies that describe medieval mechanisms with complex precision. The aim of this work is to reconstruct and study from a historical and technological point of view (...) two of the ancient artifacts contained in the “Book of Secrets”, the “Fortress Demolisher” and the “Magic Well”. The “Fortress Demolisher” is a war machine designed to demolish the upper part of the walls or towers and consists of a battering ram mounted on a platform that can be raised several meters above the ground using a scissor mechanism. The “Magic Well” is a mechanism with several pulleys whose purpose is to raise water several meters from the bottom of a well by collecting a small portion of rope. To reconstruct the two artifacts, a digital model and a detailed study of the geometry and operation of the mechanisms, were first carried out. 3D printing, using the Fused Deposition Modelling technology, made the physical reproduction. The digitization and physical reproduction by 3D printing of the mechanisms represent an update of the traditional ways of transmitting knowledge. The use of these new technologies makes the knowledge more accessible, understandable and attractive. (shrink)

The first European settlements in the new world faced technical issues with the help of the XVI century scientific advances. Besides briefly exposing the scientific and technological situation, this paper explores, with the help of reverse engineering, two singular mechanical wits representative of the technological advances introduced in America to overcome different problems. Firstly, a pump, based on an alternative movement system through crankshafts and pistons used against the continuous flooding suffered in the Ciudad de México valley. Although flooding remained (...) a problem (it was solved in the XX century), hydraulic pumps were essential for continuous soil drainage. Secondly, a port crane for handling cannons, military devices, and construction materials during the Lima fortification in the XVII century. For both cases, reverse engineering, through engineering methods, Computer-Aided Design CAD programs, and additive manufacturing, provides virtual and/or tangible mockups that help to analyze and improve our knowledge about the dimensions, materials, and functions of used (and currently lost) mechanical systems during the American colonization.

Recent arguments claim that behavioral science has focused – to its detriment – on the individual over the system when construing behavioral interventions. In this commentary, we argue that tackling economic inequality using both framings in tandem is invaluable. By studying individuals who have overcome inequality, “positive deviants,” and the system limitations they navigate, we offer potentially greater policy solutions.

In cognitive science, there is a tacit norm that phenomena such as cultural variation or synaesthesia are worthy examples of cognitive diversity that contribute to a better understanding of cognition, but that other forms of cognitive diversity (e.g., autism, attention deficit hyperactivity disorder/ADHD, and dyslexia) are primarily interesting only as examples of deficit, dysfunction, or impairment. This status quo is dehumanizing and holds back much-needed research. In contrast, the neurodiversity paradigm argues that such experiences are not necessarily deficits but rather (...) are natural reflections of biodiversity. Here, we propose that neurodiversity is an important topic for future research in cognitive science. We discuss why cognitive science has thus far failed to engage with neurodiversity, why this gap presents both ethical and scientific challenges for the field, and, crucially, why cognitive science will produce better theories of human cognition if the field engages with neurodiversity in the same way that it values other forms of cognitive diversity. Doing so will not only empower marginalized researchers but will also present an opportunity for cognitive science to benefit from the unique contributions of neurodivergent researchers and communities.

Burnout is characterized by emotional exhaustion and caused by exposure to excessive and prolonged stress related to job conditions. Moreover, burnout is highly prevalent among health care professionals. The aim of this study is, first, to examine the mediating role of social support over the effect of burnout in health care professionals and, second, to explore potential gender differences. A convenience sample of 1,035 health professionals from Ecuador, including 608 physicians and 427 nurses, was surveyed using the Maslach Burnout Inventory, (...) Social Support Survey, and General Health Questionnaire as measures of burnout, social support, and general health, respectively. Social support was found to mediate the negative effects of burnout on health regardless of gender. Differences across the three dimensions of burnout and health are further discussed, along with their implications for designing effective burnout interventions for health care professionals in Ecuador.

After presenting a brief history of philosophy in Hispanic-America since the XVI century, we discuss whether the idea of province and empire is applicable to contemporary Hispanic-American philosophy, investigate the form these ideas adopt in this region, and inquire into the ways in which provincialism i s present in philosophical work. We conclude that there are three main groups that understand their peripheral position in different ways, with different views on the way in which they should insert into the mainstream (...) of Western philosophy.

BackgroundThe proper and ethical inclusion of PWLHIV and their young children in research is paramount to ensure valid evidence is generated to optimize treatment and care. Little empirical data exists to inform ethical considerations deemed most critical to these populations. Our study aimed to systematically review the empiric literature regarding ethical considerations for research participation of PWLHIV and their young children.MethodsWe conducted this systematic review in partnership with a medical librarian. A search strategy was designed and performed within the following (...) electronic databases: Ovid MEDLINE, Embase and CINAHL. We screened titles and abstracts using the following inclusion criteria: (1) a study population of PWLHIV or children under 5 years of age; and (2) collection of qualitative or quantitative data regarding ethics of research participation. Excluded were reviews, commentaries, policy statements, clinical care-related ethics concerns, abstracts, case studies, or studies unrelated to HIV research. Studies were appraised for quality, data were extracted, and studies were qualitatively analyzed using a principle-based ethical framework within the Belmont Report.ResultsOf the 7470 titles identified, 538 full-text articles were reviewed for eligibility and only three articles met full criteria for inclusion within this review. While we allowed for inclusion of studies involving young children born to mothers with HIV, only articles focused on PWLHIV were identified. Within the results of these studies, four themes emerged: (1) adequacy of informed consent; (2) consideration of paternal involvement; (3) balancing risks; and (4) access to research and treatment. A strength of this review is that it included perspectives of international research investigators, community leaders, and male partners. However, only two studies collected empiric data from PWLHIV regarding their experiences participating in researchConclusionResearchers and funding agencies should be aware of these considerations and appreciate the value of and critical need for formative research to ensure clinical trials involving PWLHIV promote ethical, well-informed research participation and, ultimately, improve care outcomes. More research is needed to create a comprehensive ethical framework for researchers when conducting studies with PWLHIV. (shrink)

Patients who enter the health care system for acute care may become “permanent” patients of the hospital when a lack of resources precludes discharge to the next level of post-acute care. Legal, professional, and ethical norms prohibit physician and acute care hospital “dumping” of these patients. However, limitless use of hospital resources for indefinite stays is untenable. In the absence of hospital policy addressing this specific issue, the availability of financial support will be determined by health care professionals' willingness to (...) advocate for the patient and negotiate with hospital administrators and the ability and willingness of administrators to authorize the use of hospital resources. We propose five mid-level ethical principles to guide advocacy and administrative decision-making about provision of financial support for post-acute care for those patients who cannot afford it. We use two actual, de-identified cases to illustrate how these principles can be used to make reasoned, consistent decisions about the provision of post-acute financial support. (shrink)

Patients who enter the health care system for acute care may become “permanent” patients of the hospital when a lack of resources precludes discharge to the next level of post-acute care. The care of these patients contributes to the rising costs of health care and will remain largely unaffected by the Affordable Care Act. For example, some resources may be available for treatment of undocumented persons, but Medicaid enrollment is unavailable for this population. Even where patients have access to Medicaid, (...) it takes up to three months between applying for and actually receiving Medicaid benefits. During that time, patients may be ready for hospital discharge. However, post-acute care facilities have no financial incentive or legal obligation to accept patients with no insurance or only pending Medicaid coverage. (shrink)

While valuable work has been done addressing clinical ethics within established healthcare systems, we anticipate that the projected growth in acquisitions of community hospitals and facilities by large tertiary hospitals will impact the field of clinical ethics and the day-to-day responsibilities of clinical ethicists in ways that have yet to be explored. Toward the goal of providing clinical ethicists guidance on a range of issues that they may encounter in the systematization process, we discuss key considerations and potential challenges in (...) implementing system-wide ethics consultation services. Specifically, we identify four models for organizing, developing, and enhancing ethics consultation activities within a system created through acquisitions: train-the-trainer, local capacity-building, circuit-riding, and consolidated accountability. We note each model’s benefits and challenges. To our knowledge, this is the first paper to consider the broader landscape of issues affected by consolidation. We anticipate that clinical ethicists, volunteer consultants, and hospital administrators will benefit from our recommendations. (shrink)

Online education has become an essential component of education. Thus, several factors, such as the student’s learning strategy and motivation, generally contribute to their academic success. This study investigates the relationship between learning strategies, motivation, and online learning environment among 150 first-year college students. Employing correlational design, the statistical findings of the study reveal that the r coefficient of 0.59 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision (...) to reject the null hypothesis. Hence, a significant relationship exists between learning strategies, motivation, and the online learning environment. (shrink)

This study examines the way that consent is reported for participation in school-based research involving children or young people aged from 5 to 16 years. Databases containing descriptions of research identified during systematic reviews were surveyed to determine to what extent consent is sought, and from whom, and to see whether reporting varied by study characteristics such as the age of participants, the country in which the research was carried out, research design and substantive area of study. Of a total (...) of 489 studies in school settings involving children or young people, less than a third reported seeking consent. Only one in seven sought consent from children or young people themselves. Consent was reported significantly more frequently in studies sourced from health promotion reviews, when compared to those sourced from education reviews. Codes of practice indicate that researchers should seek consent from research participants. This study demonstrates that these principles are often not reflected in practice. (shrink)

Gender and social inclusion efforts in agricultural development are focused on making uptake of agricultural technologies more equitable. Yet research looking at how gender relations influence technology uptake often assumes that men and women within a household make farm management decisions as individuals. Relatively little is understood about the dynamics of agricultural decision-making within dual-adult households where individuals’ management choices are likely influenced by others in the household. This study used vignettes to examine decision-making related to maize plot management in (...) 698 dual-adult households in rural Kenya. The results indicated a high degree of joint management of maize plots (55%), although some management decisions—notably those related to purchased inputs—were slightly more likely to be controlled by men, while other decisions—including those related to hiring of labor and maize end uses—were more likely to be made by women. The prevalence of joint decision-making underscores the importance of ensuring that both men’s and women’s priorities and needs are reflected in design and marketing of interventions to support maize production, including those related to seed systems, farmer capacity building, and input delivery.

The clinical ethicist met with Ms. H to clarify what information she wants and does not want to know. First, she wants to receive any treatment that could prolong her life, regardless of how the treatment affects her ability to engage in activities of daily living. Second, she wants to be included in the decision‐making process as much as possible, as long as clinicians use only “positive” language. Ms. H considers the words “dying,” “chemotherapy,” “radiation,” and “cancer” to be “bad (...) words.” For conversations in which these words cannot be avoided, she wants her clinicians to talk to her son. Her desired engagement includes hearing about risks, benefits, and alternatives to treatments if clinicians use only “positive” language. Finally, she says that she rarely sees doctors and that she is “very scared” of hospitals, despite exhibiting a comfortable demeanor.Should clinicians honor Ms. H's waiver of specified information and, if so, to what degree?

Hospital administrators may lack familiarity with what clinical ethicists do (and do not do), and many clinical ethicists report receiving inadequate financial support for their clinical ethics consultation services (CECSs). Ethics consultation is distinct in that it is not reimbursable by third parties, and its financial benefit to the hospital may not be quantifiable. These peculiarities make it difficult for clinical ethicists to resort to tried-and-true outcome-centered evaluative strategies, like cost reduction or shortened length of stay for patients, to show (...) a “need” for ethics consultation. Likewise, it can be difficult for clinical ethicists to “speak the same language” as healthcare administrators and managers, which, in turn, means that CECSs run the risk of being unable to demonstrate value to those who pay for the service. The purpose of this descriptive article is to provide practical guidance to clinical ethicists and program directors on how to cultivate administrative support for a CECS. Specifically, we discuss two elements that clinical ethics leaders must critically appraise and successfully argue to meet the expectations of administrators— the value of a CECS and its fit in clinical workflow.

This book addresses “containment” as it relates to interlocking discourses around the “War on Terror” as a global effort and its link to race and sexuality within the United States. The project emerged from the recognition that the events of 11 September 2001, prompted new efforts at containment with both domestic and international implications.

Histamine is a multifunctional biogenic amine with relevant roles in intercellular communication, inflammatory processes and highly prevalent pathologies. Histamine biosynthesis depends on a single decarboxylation step, carried out by a PLP-dependent histidine decarboxylase activity (EC 4.1.1.22), an enzyme that still remains to be fully characterized. Nevertheless, during the last few years, important advances have been made in this field, including the generation and validation of the first three-dimensional model of the enzyme, which allows us to revisit previous results and conclusions. (...) This essay provides a comprehensive review of the current knowledge of the structural and functional characteristics of mammalian histidine decarboxylase.

This article responds to logical and social theses proposed by Professor José Medina in discussing the relativity of identity. In exploring the metaphor of family resemblance, the author argues that its causal mechanism is biological, not social; particular features of being a woman, or of belonging to a racial or ethnic group, cannot be reduced to social constructions. The article skeptically discusses the supposed importance of sex, race, and ethnicity to a person’s individual identity, and suggests that moral significance (...) finds its origin and grounding elsewhere. It concludes that no liberation can be ‘complete, or even adequate’ until it liberates the mind from ‘“scripts” rooted in the delusion of “collective identities”’. (shrink)

In 1966, island biogeographer Sherwin Carlquist published a list of 24 principles governing long-distance dispersal and evolution on islands. The 24 principles describe many aspects of island biology, from long-distance dispersal and establishment to community change and assemblage. Although this was an active period for island biogeography, other models and research garnered much more attention than did Carlquist’s. In this review, over 40 years of support for or against Carlquist’s principles is presented. Recent work has supported most of the 24 (...) principles, and improved methodologies have generally substantiated his initial claims. However, Carlquist’s original work and ideas remain relatively under-represented in the biogeographic literature. Use of philosophical model domains provides one explanation as to why Carlquist’s work has received little attention. Carlquist’s principles are largely natural history tests, and don’t translate well into the theoretical, design of preserves, or the experimental domains—whereas other competing models do well in such domains.

This study examined the relationship between moral distress intensity, moral distress frequency and the ethical work environment, and explored the relationship of demographic characteristics to moral distress intensity and frequency. A group of 106 nurses from two large medical centers reported moderate levels of moral distress intensity, low levels of moral distress frequency, and a moderately positive ethical work environment. Moral distress intensity and ethical work environment were correlated with moral distress frequency. Age was negatively correlated with moral distress intensity, (...) whereas being African American was related to higher levels of moral distress intensity. The ethical work environment predicted moral distress intensity. These results reveal a difference between moral distress intensity and frequency and the importance of the environment to moral distress intensity. (shrink)

IPCC SPECIAL REPORT ON CLIMATE CHANGE AND LAND (SRCCL) -/- Chapter 3: Climate Change and Land: An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems.

Background:Clinical investigation is a growing field employing increasing numbers of nurses. This has created a new specialty practice defined by aspects unique to nursing in a clinical research context: the objectives, setting, and nature of the nurse–participant relationship. The clinical research nurse role may give rise to feelings of ethical conflict between aspects of protocol implementation and the duty of patient advocacy, a primary nursing responsibility. Little is known about whether research nurses experience unique ethical challenges distinct from those experienced (...) by nurses in traditional patient-care settings.Research objectives:The purpose of the study was to describe the nature of ethical challenges experienced by clinical research nurses within the context of their practice.Research design:The study utilized a qualitative descriptive design with individual interviews.Participants and research context:Participating nurses self-identified as having experienced ethical challenges during screening. The majority were Caucasian, female, and worked in outpatient settings. Approximately 50% had > 10 years of research experience.Ethical considerations:The human subjects review board approved the study. Written informed consent was obtained.Findings:Predominant themes were revealed: the inability to provide a probable good, or/do no harm, and dual obligations. The following patterns and subthemes emerged: conflicted allegiances between protocol implementation, needs of the participant, desire to advance science, and tension between the nurse–patient therapeutic relationship versus the research relationship.Discussion:Participants described ethical challenges specific to the research role. The issues are central to the nurse–participant relationship, patient advocacy, the nurse’s role in implementing protocols, and/or advancing science.Conclusion:Ethical challenges related to the specialized role of clinical research nurses were identified. More research is warranted to fully understand their nature and frequency and to identify support systems for resolution. (shrink)

Previous research addressing the association between leisure and happiness has given rise to the hypothesis that informal social activities might contribute more to happiness than solitary activities. In the current study, we tested how the two types of leisure—social and solitary—contribute to a person’s subjective sense of well-being. For the empirical estimate, we used four consecutive quarters of data collected from 533 people over the age of 16, from 13 Tsimane’ hunter-farmer villages in the Bolivian Amazon. Results suggest that only (...) social, not solitary, leisure has a positive and statistically significant association with subjective well-being. The association between solitary leisure and subjective well-being was negligible or negative. Future research should focus on emic definitions of social and solitary time, for solitary time might not always be equivalent to leisure and productive group activities might substitute for social leisure.

Modern moral and political philosophy is in debt with natural law theory, both in its ancient and mediaeval elaborations. While the very notion of a natural law has proved highly controversial among 20th Century scholars, the last decades have witnessed a renewed interest in it. Indeed, the threats and challenges as result of multiculturalism, plural societies and global changes have generated a renewed attention to natural law theory. Clearly, it offers solid basis as possible framework to a better understanding of (...) human goods without contradictions and partial bias. The purpose of the present volume is to provide an overview of the history of this concept (Cicero, St. Paul, Aquinas, Melanchthon, Montaigne, Descartes, Leibniz, Hume, Burke, Kant, MacIntyre, etc.) as well as a deep understanding of ongoing research, both in Europe and in America. Furthermore, the specificity of these studies will be of particular value to philosophers, law-philosophers, historians, anthropologists, sociologists and theologians, and those concerned on such issues as the relation between law and moral norm, law and practical reason, and the presence of the idea of natural law in several prominent thinkers. It includes a selected bibliography on natural law. The book also provides an excellent introduction to several of the major topics in natural law theory making it useful both as a reference text and as a sourcebook for academics alike. Natural law is a rich, complex, and highly disputed term. Since its first appearances in the history of Western civilization, it has been used both to point to God as the source of the moral order and to assert that there is an objective order of justice in nature that men and their laws ought to respect. In modern times, natural law theory gave birth to what we usually call "human rights." Unlike the meaning of the term, the importance of an ongoing debate on natural law and on the theories related to it is undisputable. This is why I welcome today this new collection of essays edited by Alejandro Nèstor Garcìa Martìnez, Mario Å ilar and Josè M. Torralba. Natural Law: Historical, Systematic and Juridical Approaches includes a wide variety of studies, covering key authors and issues in natural law theory. Younger students will appreciate the clarity of the chapters, and more trained readers the detailed and accurate bibliographical references that each of them offers. The editors's choice to go from a historical approach to contemporary theories, and then to theoretical and more practical issues is also commendable. Students in philosophy and in legal theory will greatly benefit from this book. Fulvio Di Blasi, author of God and the Natural Law: A Rereading of Thomas Aquinas. (shrink)

En este artículo se parte de la crítica de Feuerbach a la religión para recuperar el sentido humanista de dicha crítica, que más que una afirmación del ateísmo o una negación de la existencia de Dios es una defensa de la dignidad y de la libertad humana.

Die in diesem Band versammelten Essays erörtern die Frage nach der Möglichkeit des Verstehens menschlichen Handelns ohne den Rückbezug auf moralische Werte und Normen. Obwohl die Autoren sich dieser Frage auf ganz unterschiedliche, manchmal divergierende, Weisen nähern, verbindet sie alle die Annahme, es sei nicht wünschenswert oder sogar inkohärent, das menschliche Handeln grundsätzlich unabhängig von moralischen Werten zu betrachten. Die Herausgeber haben sich um eine für Philosophen und Gesellschaftswissenschaftler gleichermaßen attraktive Beitragssammlung bemüht. Die Verknüpfung philosophischer und soziologischer Perspektiven könnte zur (...) Klärung gegenseitiger Missverständnisse beitragen, die aufgrund eines mangelhaften Dialogs zwischen der philosophischen und soziologischen Handlungstheorie erwachsen sind. In diesem Band enthalten sind Essays von Terry Pinkard, Sebastian Rödl, Dieter Schönecker, Ana Marta González, John Levi Martin, Alejandro N. García Martínez, Sophie Djigo, Teresa Enríquez und Evgenia Mylonaki. The essays in this volume address the question of whether we can understand human action without reference to moral norms or values. Although the authors approach this question in different and sometimes even incompatible ways, they are united in thinking that it is undesirable or even incoherent to treat human agency as if it were conceptually independent of value questions. The editors have attempted to invite contributions that would be interesting to both philosophers and social theorists. The conjunction of philosophic and sociological perspectives might help to overcome some of the mutual misunderstandings that have been fostered by a lack of dialogue between the philosophic and sociological action theory. The volume includes essays by Terry Pinkard, Sebastian Rödl, Dieter Schönecker, Ana Marta González, John Levi Martin, Alejandro N.

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

School psychologists often break confidentiality if confronted with risky adolescent behavior. Members of the National Association of School Psychologists ( N = 78) responded to a survey containing a vignette describing an adolescent engaging in risky behaviors and rated the degree to which it is ethical to break confidentiality for behaviors of varying frequency, intensity, and duration. Respondents generally found it ethical to break confidentiality when risky adolescent behaviors became more dangerous or potentially harmful, although there was considerable variability between (...) respondents. Significant gender effects were found between male and female respondents for alcohol use, and a significant Form Type (i.e., male or female vignette) Frequency/Duration interaction was observed for antisocial behaviors. School psychologists could benefit from further training in ethical decision making because these ethical dilemmas are not always clear-cut. (shrink)
