Scientific research is growingly increasingly reliant on "microwork" or "crowdsourcing" provided by digital platforms to collect new data. Digital platforms connect clients and workers, charging a fee for an algorithmically managed workflow based on Terms of Service agreements. Although these platforms offer a way to make a living or complement other sources of income, microworkers lack fundamental labor rights and basic safe working conditions, especially in the Global South. We ask how researchers and research institutions address the ethical issues involved (...) in considering microworkers as "human participants." We argue that current scientific research fails to treat microworkers in the same way as in-person human participants, producing de facto a double morality: one applied to people with rights acknowledged by states and international bodies (e.g., the Helsinki Declaration), the other to guest workers of digital autocracies who have almost no rights at all. We illustrate our argument by drawing on 57 interviews conducted with microworkers in Spanish-speaking countries. (shrink)

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)

Using a recent result of Busch and Gudder, we reconsider a theorem of Ludwig which allows one to identify a class of effect automorphisms as the symmetry transformations in quantum mechanics.

Como casi todos los conceptos fi losófi cos, el de «validez normativa» tiene altos grados de ambigüedad y de vaguedad. En este trabajo me encargo de analizar la postura de distintos autores que han tratado de dar respuesta a la pregunta ¿qué significa que una norma sea «válida»? Para ello, tomo como hilo conductor la obra de Ernesto Garzón Valdés. Esto se debe a que los trabajos de Ernesto Garzón dedicados a este tema, le ofrecen al lector un análisis crítico (...) y comprensivo de algunas de las posturas teóricas más relevantes sobre el concepto de validez normativa. Asimismo, trabajar a través de su obra tiene un doble benefi cio: por un lado, no sólo nos permite conocer a fondo la postura teórica de autores que pertenecen a distintas corrientes del pensamiento, como Hans Kelsen, H.L.A. Hart, Francisco Suárez o von Wright por ejemplo, sino que, por el otro, nos permite conocer la postura del mismo Garzón y sus críticas a los diferentes modelos conceptuales. (shrink)

In this paper art history and visual studies, the disciplines that study visual culture, are presented as a field whose conjectural paradigm can be used to understand the epistemic problems associated with abduction. In order to do so, significant statements, concepts and arguments from the work of several specialists in this field have been highlighted. Their analysis shows the fruitfulness and potential for understanding the study of visual culture as a field that is interwoven with the assumptions of abductive cognition.

Ethical decision-making in school administration has received considerable attention in educational leadership literature. However, most research has focused on principals working in secondary school settings while studies that explore ethical reasoning processes of academic deans have been significantly few. This qualitative study aims to describe the ethical decision-making processes employed by a select group of Filipino college deans in solving ethical dilemmas using the ethical paradigms proposed in the works of Starratt (Educ Adm Q 27:185–202, 1991) and Shapiro and Stefkovich (...) (Ethical leadership and decision-making in education: applying theoretical perspectives to complex dilemmas, 2005) as frameworks for the analysis. Data was gathered using semi-structured interviews and field text was analyzed using deductive thematic analysis. Findings of this study show that majority of the deans chose to share ethical dilemmas involving students and teachers. The findings also show the ethical frameworks of care, justice, and profession as the dominant paradigms utilized by Filipino deans and their preference for adopting multiple ethical frameworks when making their decisions. Most of the ethical dilemmas which the deans narrated relate to their tasks of academic administration such as monitoring student performance, faculty evaluation and maintaining school discipline. Interestingly, only a few dilemmas involving university administrators were expressed, and dilemmas that refer to broader societal issues usually associated with school administrators’ utilization of the ethic of critique were also significantly left out in the narratives of this study. This paper intends to contribute to current literature by expanding research to administrators working in the context of higher education in the Philippine setting. The findings of this study could serve as knowledge base in designing ethics courses to enhance educational leaders’ ethical decision-making skills. The study also provides useful insights of ethical decisions and reasoning processes employed by academic administrators in resolving real life ethical dilemmas that could be useful at the practical level for aspiring and practicing deans.

This phenomenological study intends to capture and describe Filipino college deans’ lived experiences of ethical dilemmas as they carry out their work as administrators. Using semistructured in-depth interviews and following Collaizzi’s method, data was collected and subjected to cool and warm analyses yielding a set of themes and sub-themes that typify what these deans consider to be ethical dilemmas. The resulting ‘Wheel’ of School Leaders’ Ethical Dilemmas depicts the nature of the dilemmas faced by these deans, the critical incidents which (...) trigger the onset of the dilemmas, and the value conflicts that are embedded in them. This article intends to add to the growing body of research on ethical decision making in educational management, particularly on the ethical dilemmas faced by Filipino college deans. At a practical level, the findings of this study provide valuable resource to assist practicing and aspiring deans to be more adept in identifying the moral and ethical dimensions of their work as academic administrators. Finally the findings of this study could serve as a knowledge base for curriculum planners in designing ethics courses offered in educational leadership programs in the Philippines to develop academic leaders’competencies and skills in ethical decision making.

The chapter reports on the findings of a grounded theory study on the moral sensitivity practice of Filipino college deans. It centers on the exposition of a conceptual model which expands the construct of moral sensitivity beyond the initial stage of moral problem recognition and depicts three processes of knowing facts, understanding people, and understanding oneself as fundamental processes to moral sensitivity. A set of seven distinct practices were also identified as subcomponents of moral sensitivity. The chapter concludes by highlighting (...) the level of complexity involved in moral problem identification in real-life settings and the consequent need for developing administrators’ moral sensitivity skills through formal courses in ethics as part of school administrator preparation programs.

RESUMO O objetivo deste artigo é analisar a concepção de liberdade encontrada em "Discourses concerning government" de Algernon Sidney. Mantendo a perspectiva republicana, a liberdade é definida pela ausência de dominação, ou seja, pela não submissão, sujeição ou exposição à vontade arbitrária de outra pessoa; e assumindo a perspectiva jusnaturalista, a liberdade é considerada um direito natural, inerente à condição humana, que deve ser preservado e assegurado pela autoridade política. Pretende-se discutir como Sidney articula essas duas perspectivas em sua teoria (...) política, projetando a concepção republicana de liberdade na modernidade.ABSTRACT The objective of this paper is to analyze the concept of freedom found in Algernon Sidney’s "Discourses Concerning government". Keeping the republican thought, freedom is defined by the absence of domination, i.e., the denial of submission, bondage or exposure to the arbitrary will of another person; and taking the jusnaturalist thought, freedom is considered a natural right inherent to the human condition, which must be preserved and guaranteed by the political authority. I intend to discuss how Sidney articulates these two perspectives in his political theory, outlining the republican conception of freedom in modernity. (shrink)

Gentile's philosophy merits the attention of every serious thinker, for it presents the doctrine that reality is spiritual in a more uncompromising form than is to be found elsewhere, and claims to solve on this principle all the great problems that have beset the history of metaphysic. His own name for it is Absolute or Actual Idealism . For Gentile, nothing is real but the Spirit, and by the Spirit he means the pure act of self-conscious thinking. “The subject that (...) conceives itself in conceiving All is the reality itself.” In the act of conscious thinking, the Spirit is present in its entirety as subject ; generating therein by its own creative spontaneity a world of objects, and resolving the products of this act of objectification into the womb that gave them birth. In this immanent dialectic–pure subject , pure object , subject-object –lies the rhythmic life-history of the Spirit. “Our doctrine,” writes Gentile, “is the theory of the Spirit as act which posits its object in a multiplicity of objects, resolving their multiplicity and objectivity in the unity of the subject itself.” For such a doctrine, transcendence is the enemy, the Goliath whom Gentile has gone forth to slay. He confronts us, on almost every page of his writings, with an ineluctable dilemma. Either a philosophy of sheer immanence, or reality is unknowable. (shrink)

The two basic forms of action distinguished in the preceding articles, viz., moral action, where praxis is for praxis sake, and action for a good, where praxis is for the sake of theôria, are found in close relationship to one another in human life. The part they play is rather that of abstract moments in a practical process than that of self-contained and isolable bits of conduct. No philosopher is likely to discount the importance of thus analysing the concrete into (...) its factors before he rectifies the abstraction by showing how they co-operate in actual experience. In any individual biography we can find acts and courses of action in which duty is the dominant motive, and others in which the dominant motive is desire of good. Similarly, when we compare different biographies with one another, some exemplify most strikingly the struggle for righteousness against unruly passion, others the spontaneous aspiration of the soul to attain the goal of its desire. But neither the moral law nor the summum bonum wields an exclusive sovereignty. St. Paul and Luther, in their warfare against carnal desire, drew strength from the ideal vision; nor were St. Bernard or Spinoza, for all their absorption upon union with the divine, strangers to the call of moral obligation. In the lives of ordinary men, the types of conduct are, perhaps, more evenly balanced; yet here also the distinction is discernible. Moreover, it is easy to see how, despite their intrinsic difference, they come to be associated and “by just exchange” to effect a mutual enrichment. (shrink)
