Given recent advances in technology, connectivity, and the popularity of social media platforms, recent literature has devoted great attention to problematic Facebook use. However, exploring the potential predictors of problematic social media use beyond Facebook use has become paramount given the increasing popularity of multiple alternative platforms. In this study, a sample of 584 social media users was recruited to complete an online survey assessing sociodemographic characteristics, patterns, and preferences of social media use, problematic social media use, social media use (...) motives, psychological well-being, self-esteem, and positive and negative affect. Results indicated that 6.68% of all respondents could be potentially classed as problematic users. Moreover, further analysis indicated that intrapersonal motive, negative affect, daily social media use, surveillance motive, and positive affect each predicted PSMU. These variables accounted for about 37% of the total variance in PSMU, with intrapersonal motive driving the greatest predictive contribution, over and above the effects of patterns of social media use and sociodemographic variables. These findings contribute to the increasing literature on PSMU. The results of this study are discussed in light of the existing literature on PSMU. (shrink)

Rare genetic diseases collectively impact millions of individuals in the United States. These patients and their families share many challenges including delayed diagnosis, lack of knowledgeable providers, and limited economic incentives to develop new therapies for small patient groups. As such, rare disease patients and families often must rely on advocacy, including both self-advocacy to access clinical care and public advocacy to advance research. However, these demands raise serious concerns for equity, as both care and research for a given disease (...) can depend on the education, financial resources, and social capital available to the patients in a given community. In this article, we utilize three case examples to illustrate ethical challenges at the intersection of rare diseases, advocacy and justice, including how reliance on advocacy in rare disease may drive unintended consequences for equity. We conclude with a discussion of opportunities for diverse stakeholders to begin to address these challenges. (shrink)

Are restrictive measures and duties to care ethically reasonably acceptable to faith-based organizations? This study describes the perceptions of individually interviewed spiritual leaders of the disease control measures used during the recent SARS outbreak in Toronto. Four central themes were identified: the relationship between religious obligation and civic responsibilities; the role of faith-based organizations in supporting public health restrictive measures; the reciprocal obligations of public health and religious communities during restrictions; and justifiable limits to duties to care. We conclude that, (...) within certain constraints, spiritual leaders find restrictive measures ethically reasonable and that spiritual leaders can play an important role during pandemic and epidemic control planning. Public health officials should therefore include them in the early and ongoing deliberations of the criteria and logistics for implementation during public health emergencies. (shrink)

The standardized precipitation index is one of the most widely used indices for characterizing and monitoring drought in various regions. SPI's applicability has regional and time-scale constraints when it observes in several homogeneous climatic regions with similar characteristics. It also does not provide sufficient knowledge about precipitation deficits and the spatiotemporal evolution of drought. Therefore, a new method, the regional spatially agglomerative continuous drought probability monitoring system, is proposed to obtain spatiotemporal information and monitor drought characteristics more expeditiously. The proposed (...) framework uses spatially agglomerative precipitation and copulas’ functions to continuously monitor the drought probability in the homogenous region. The RSACDPMS is validated in the region of the Northern area of Pakistan. The outcomes of the current study provide a better quantitative way to obtain appropriate information about precipitation deficits and the spatiotemporal evolution of drought. (shrink)

Les livres deutérocanoniques constituent un «intertestament» entre les écrits de la Bible rabbinique et ceux du Nouveau Testament chrétien. Ils sont sur une frontière, un fossé ou un pont entre le christianisme naissant et le judaïsme renaissant après 135. Ils font aussi le lien entre la Gola araméenne et la Diaspora hellénistique. Les écrits intertestamentaires – et spécifiquement les deutérocanoniques qui sont comme un «intertestament» canonique – sont vraiment nécessaires à la compréhension de la Bible.

Epistemologias: Nesta obra, além dos capítulos de cunho epistemológico e antropológico, estão incluídos textos que problematizam a colonialidade e a decolonialidade. Essas concepções dinamizam a aproximação do pensamento crítico mundial a partir do lugar de reflexão dos(as) autores(as) dos continentes africano e latino-americano. Os temas abordados discutem a função que o racismo epistêmico desempenhou na reprodução de privilégios na estrutura social do pensamento contemporâneo. Assim, pressupostos epistemológicos aqui trabalhados sinalizam uma visão de mundo e de ser humano. Os apreciadores de (...) uma boa leitura identificarão nos quatro eixos (Filosofia, Bioética, Teologia e Direitos humanos) novos horizontes e o rompimento de fronteiras da afrocentricidade e ancestralidade epistemológica do pensamento diaspórico. -- Pucpress.

This addition—hence the title Mantissa—to the rich vein of information about Constantine Samuel Rafinesque is in fact a supplement to Charles Boewe's own revised and enlarged edition of Thomas J. Fitzpatrick's book Rafinesque .The details of the peripatetic life of Rafinesque, one of America's most original yet undisciplined naturalists, are too well known to bear repeating here. Suffice it to say that because of the vicissitudes of his life—his perpetual wandering between and within Europe and frontier America, his impecunious circumstances (...) that forced him to find different ways of making a living—finding and identifying his publications is a bibliographer's nightmare. Even now, more than 160 years after his death and with the benefit of serious studies by Fitzpatrick and Boewe, as well as by Richard E. Call and Elmer D. Merrill, among others, we can only approximate the number of his publications, including both original titles and republications. Probably we will never have a complete list of Rafinesque's publications because he published regularly in newspapers, broadsides, sales catalogues, privately printed journals, and other ephemera that are infrequently archived. Even his own references to “published” works cannot be trusted as, to him, this term included papers that he sent to journals but were never published. On the other hand, Rafinesque complained to one correspondent that he never knew whether some of these manuscripts were ever published or he learned only years later that they had been. The total number has been estimated at about a thousand, but, as Boewe points out, this number is based on Fitzpatrick's faulty numbering system in which each version of a paper or volume of a multivolume work was given a number. Thus Fitzpatrick's system, continued by Boewe, represents serial numbers, not individual titles. Rafinesque's own estimate was 220, a number Boewe now thinks is a reasonable guess.The Mantissa is an important addition to Rafinesquiana. It lists twenty hitherto‐unrecorded publications by Rafinesque, thirty‐three new translations or reprints, and more than two hundred newly listed secondary references. For the first time we have a list of every manuscript letter written by Rafinesque that is known to exist, and Boewe provides a documented discussion of Rafinesque publications still remaining to be discovered. Several titles known to me, however, are missing from Mantissa, but Boewe's book represents a learned guide for the next scholar willing to take up the challenge and carry on the search. The newly listed manuscript letters will doubtless be particularly helpful in providing leads to undiscovered publications and other facets of Rafinesque's still not completely understood life. Among his correspondents were fellow naturalists such as John James Audubon, Joseph Banks, Benjamin Barton, Charles Bonaparte, Alexandre Brongniart, Augustin de Candolle, Georges Cuvier, Amos Eaton, Asa Gray, William Jackson Hooker, Muhlenberg, Ord, Paolo Savi, James Edward Smith, William Swainson, and John Torrey, as well as prominent leaders of the day, including John Adams, De Witt Clinton, Eleuthère Irénée du Pont, George IV, Thomas Jefferson, and Joel Roberts Poinsett. A total of 346 letters are listed.More important, Boewe has given us the benefit of his many years of scholarly searching and thinking about Rafinesque in his discussions entitled “Hints about Unlisted Titles,” “Letters as a Source of Leads,” and “Hints in Publications.” We learn, for example, that Rafinesque signed some of his papers simply as “Constantine” or “Linneus.” The Mantissa makes it abundantly clear why arriving at a complete account of Rafinesque's writings is an elusive goal, but Boewe shows us that the attempt still offers an exciting trail to follow.

Before examining de Moivre's contributions to the science of mathematics, this article reviews the source materials, consisting of the printed works and the correspondence of de Moivre, and constructs his biography from them. The analytical part examines de Moivre's contributions and achievements in the study of equations, series, and the calculus of probability. De Moivre contributed to the continuing development from Viète to Abel and Galois of the theory of solving equations by means of constructing particular equations, the roots of (...) which can be written in the form $$\sqrt[n]{{a + \sqrt b }} + \sqrt[n]{{a - \sqrt b }}$$. He also discovered the reciprocal equations. In the course of this work de Moivre discovered an expression equivalent to (cos α+i sin α) n =cos n α+i sin n α and, following Cotes, he succeeded in expressing the nth roots of unity in trigonometric form. In the theory of series, de Moivre developed a polynomial theorem encom-passing Newton's binomial theorem and, in particular, a theorem of recurrent series useful in the calculus of probability. The demands of the calculus of probability led de Moivre to an approximation for the binomial coefficients $$\left( {_m^n } \right)$$ for large values of n. The interaction between de Moivre and James Stirling, particularly in regard to the asymptotic series for log (n!), is treated at length. This work supplied the foundation for de Moivre's limit theorem for the binomial distribution. The calculus of probability, which occupied him from 1708 onward, became in time ever more the center of de Moivre's inquiries. Proceeding from contemporary collections of gambling exercises, de Moivre, by introducing an explicit measure of probability for the so-called Laplace experiments, found the beginnings of a theory of probability. De Moivre expanded the classic application of probability calculus to games of chance by addressing himself to the problem of annuities and by adopting Halley's work with its conception of “Probability of life”. De Moivre was the first to publish a mathematically formulated law for the decrements of life derived from mortality tables. (shrink)

Das Volksmärchen L’Arbre du Bœuf vom Typ ATU 511 [Ein-, Zwei-, Dreiäuglein] ist nach P. Delarue und M.-L. Tenèze das einzige französische Märchen, welches dem Subtyp AT 511 A [Kleiner Roter Ochse] angehört. L’Arbre du Bœuf ist darüber hinaus aufgrund einiger Motive besonders interessant, weil sie vermutlich aus archaischen Glaubensvorstellungen stammen: So ist die mystische „Reise zur Sonne“ ein bestimmendes Thema, welches seinen Ursprung im indoeuropäischen Mythos findet. Der Weltbaum als Axis Mundi und die Seelenbrücke sind Verbindungen zwischen dem Dies- (...) und Jenseits, die der Märchenheld ebenso wie der Schamane bei seiner ekstatischen Reise in die lichte Himmelswelt benutzt. Magische Tier- und Helferwesen treten im Zaubermärchen auf und sind integrale Bestandteile schamanistischer Glaubenswelten. Wenn im Märchen auf oder aus dem geopferten Ochsen als heiliges Tier der Weltbaum sprießt, so findet dieses Sujet Entsprechungen in urtümlichen Kosmogonien. Damit ideell verwandt ist vielleicht das Motiv vom „Tierhorn als Weltbaum“, welches sich in archaischen kosmologischen Vorstellungen findet und sich von da her womöglich ebenso in die Märchenwelten eingemischt hat. Le conte populaire L’Arbre du Bœuf du type ATU 511 [Un Œil, Deux Yeux, Trois Yeux] d’après P. Delarue et M.-L. Tenèze est le seul conte de fées français appartenant au sous-type AT 511 A [Petit Bœuf Rouge]. En outre, L’Arbre du Bœuf est particulièrement intéressant en raison de certains motifs probablement issus de croyances archaïques : Le « voyage mystique au soleil » est un thème déterminant qui tire son origine du mythe indo-européen. L’Arbre du Monde en tant qu’Axis Mundi et le pont d’autre monde sont des liens entre l’ici et l’au-delà, que le héros de conte et le chaman utilisent dans leur voyage extatique dans le ciel lumineux. Les animaux magiques et les êtres auxiliaires apparaissent dans le conte de fées et font partie intégrante du monde de croyances chamaniques. Tout comme dans le conte de fées, l’Arbre du Monde pousse sur ou bien du bœuf sacrifié et sacré, ce motif trouve des correspondances dans les anciennes cosmogonies. Le motif de la « corne animale en tant qu’Arbre du Monde » est peut-être associé à ce concept mythique. Il se trouve dans les conceptions cosmologiques archaïques et s’est mêlé de là au monde des contes de fées. The folk tale L’Arbre du Bœuf of the type ATU 511 [One Eye, Two Eyes, Three Eyes] is according to P. Delarue and M.-L. Tenèze the only French fairy tale that belongs to the subtype AT 511 A [Little Red Ox]. In addition, L’Arbre du Bœuf is particularly interesting due to some of the motifs that probably stem from archaic beliefs: The mystical “journey to the sun” is a determining theme, which finds its origin in the Indo-European myth. The World Tree as Axis Mundi and the Soul Bridge are connections between this world and the hereafter which are harnessed by the fairy tale hero as well as the shaman in his ecstatic journey into the bright world of heaven. Magical animals and helping entities appear in the fairy tale and are fundamental parts of shamanistic beliefs. The World Tree as it sprouts on or out of the sacrificed and sacred ox finds its equivalent in ancient cosmogonies. Perhaps ideally related to this is the motif of the “animal horn as the World Tree”, which is present in archaic cosmological conceptions and has possibly interfered with the fairytale worlds as well.

Dans un texte désormais célèbre, Ferdinand de Saussure insiste sur l’arbitraire du signe dont il vante les qualités.

Résumé Nous entendons démontrer dans cet article l’importance souvent méconnue que revêt dans la morale kantienne l’analogie entre la nature sensible et la nature morale. Nous y soutiendrons en effet que sans la présence d’une telle analogie, il serait impossible pour le jugement pratique de déterminer pour des cas particuliers quelles sont les actions qu’autorise l’impératif catégorique. A cet égard, la typique du jugement pur pratique s’avérera déterminante en ceci qu’elle fournira à la loi morale le prolongement intuitif nécessaire pour (...) que soient subsumées sous elle des actions particulières. Bien qu’elle esquisse un pont entre la nature et la liberté, la typique ne saurait se réduire, comme le suggère néanmoins Yovel, à n’être qu’une forme inférieure de la synthèse achevée de la moralité et du bonheur, telle qu’on la retrouve dans le concept du souverain bien. Son caractère incontournable pour le jugement moral s’illustre en outre dans le recours systématique à ce principe par Kant lui-même lors de la discussion et de la solution des quatre dilemmes moraux présentés dans les Fondements de la métaphysique des mœurs.

La percezione musicale ha avuto un ruolo significativo nella storia della psicologia della Gestalt. Muovendo dalle critiche di Mach ed Ehrenfels alla dottrina elaborata da Helmholtz e dall’elaborazione teorica di Stumpf, destinata a fungere da ponte concettuale, il lavoro analizza la riflessione svoltasi in seno alla psicologia della Gestalt. Sorprendentemente, Köhler non si concentra sulle Gestalten musicali complesse, ma sulle qualità tonali più elementari, mostrandone la totale irriducibilità a fattori fisico-fisiologici. Sulla stessa linea è anche Hornbostel, il quale amplia tuttavia (...) il discorso mediante il richiamo al complesso antropologico dei vissuti umani, musicali ed extramusicali, che rimandano a un determinato contesto culturale, saldando così il nesso tra psicologia della Gestalt e ricerca nel campo etnomusicologico.

Les parcours migratoires placent les familles migrantes, qui traversent la Méditerranée, face à des enjeux nouveaux de transmission de gestes et de discours en fonction de stratégies identitaires aussi diverses que mouvantes. Ces familles, qui refont le voyage sans cesse entre les deux rives, s’attachent à faire le pont entre deux espaces, à faire voyager des idées, des gestes, des mots, des objets, des danses. C’est à ces dernières, accompagnées de chants et de musiques, gestes et sonorités de mémoire, qui (...) marquent le lien ou la séparation, que je m’intéresse. À partir d’un questionnement sur l’élaboration, la rencontre, mais aussi la remise en cause des identités genrées à travers l’apprentissage et la mise en œuvre des danses migrantes berbères ahidous, je me demande dans quelle mesure on peut proposer une approche diachronique et dialogique des mouvements de danses partagées au féminin et au masculin, qui font le voyage avec les migrants et qui sont les supports de l’expression d’une loyauté vis-à-vis du pays d’origine, d’une légitimité passant au travers des liens revendiqués, ou bien encore d’une position en marge des usages convenus au moment du départ en lien avec un contexte de vie différent, saisi de nouveaux modèles esthétiques.
