Depression experienced by older adults is proving an increasing global health burden, with rates generally 7% and as high as 27% in the USA. This is likely to significantly increase in coming years as the number and proportion of older adults in the population rises all around the world. Therefore, it is imperative that the effectiveness of approaches to the prevention and treatment of depression are understood. Creative arts interventions, including art, dance movement, drama and music modalities, are utilised internationally (...) to target depression and depressive symptoms in older adults. This includes interventions led by trained arts therapists as well as other health and arts professionals. However, to date there has not been a systematic review that reports effects and examines the processes (why) and mechanisms (how) of creative arts interventions are used to address depression in this older age group. This systematic review of studies on creative arts interventions for older adults experiencing depression examined: outcomes of four creative arts modalities (art, dance movement, drama, and music); with particular attention paid to processes documented as contributing to change in each modality; and mechanisms considered to result from these processes. Our analysis of 75 articles (17 art, 13 dance, 4 drama and 41 music) indicates mostly significant quantitative or positive qualitative findings, particularly for interventions led by creative arts therapists. Mechanisms of change gleaned from the studies that were common across modalities include physical (e.g. increased muscle strength; neurochemical effects, such as endorphin release), intra-personal (e.g. enhanced self-concept, strengthened agency and mastery; processing and communication of emotions), cultural (e.g. creative expression, aesthetic pleasure), cognitive (e.g. stimulation of memory) and social (e.g. increased social skills and connection), that were all considered to contribute to reduced depression and symptoms. Recommendations for future research include a stronger focus on testing of processes and mechanisms. (shrink)

En este artículo se fundamenta y promueve la necesidad de comprensión de lo local como escala de lo social, y como una producción social resultante de la acción e interacción de agentes que actúan desde diferentes escalas, intereses y objetivos. Se sostiene, además que ello ha sido un campo analítico de bajo desarrollo en Chile y América Latina, aunque se puede inventariar un conjunto de aproximaciones que directa o indirectamente se han referido a ello en el pasado. Por otro lado, (...) se incentiva y se problematiza una orientación política que, dentro de un plano de “estilos de desarrollo”, valorice las dinámicas endógenas locales, es decir con protagonismo de los agentes locales. Ello se fundamenta en la necesidad de hacer visible y proyectar poderes periféricos velados por un cierto “centralismo intelectual”, por la importancia que la calidad de los territorios locales tienen en nuestras vidas, por la necesidad de saldar cuentas con una construcción de “lo nacional” que oprimió diversidades y, finalmente, para evitar la imposición de racionalidades y agentes globales que, bajo un discurso de universalidad, impongan intereses particulares.

El término '"Dialéctica" hace referencia tanto al movimiento de autodesenvolvimento del concepto - en este caso el de derecho y, em sentido amplio - como a la estrutura de ese movimiento, al cual Hegel trata de encuadrar en esquemas provenientes de la Lógica dei concepto, especialmente en la triada 'tesis - antítesis - síntesis', lo cual potencia la complejidad dei texto y dificulta su comprensión. Uma hermenéÚtica esclarecedora de la lógica dialéctica en juego, donde a la contradicción!e cabe el papel (...) protagónico, exige tener en cuenta estos aspectos como también e: hecho de que Hegel, en su concepción de la Dialéctica asume la herencia de la filosofia aristotélica, tanto como del Idealismo Trascendental moderno, los que se entremezclan permanentemente en intrincada red de múltiples significaciones. La distinción de todos estas aspectos y de su rol en la exposición de la Filosofia del Derecho es imprescindible, tanto para una interpretación adecuada de su letra y espíritu, como de su significación actual. El presente trabajo se concibe como un intento de contribuir ai esclarecimiento de esta cuestión. (shrink)

Es wird der Nachweis versucht, dass es — ebenso wie in der Physik — auch in der Biologie komplementäre Erkenntnissysteme gibt. Wie Welle und Korpuskel in der Physik, so sind innerhalb der Biologie u.a. Form und Funktion, Innenwelt und Umwelt sowie auch vor allem Vererbung und Anpassung komplementäre Begriffsgefüge. Das wird im einzelnen diskutiert und nachgewiesen.Für die Erkenntnis der Wirklichkeit im Ganzen folgt daraus, dass systematisch aufgebaute Erkenntnisgefüge nur in Teilbereichen des Wirklichen möglich sind — nur in der klassischen Mechanik, (...) der Elektrodynamik, der vergleichenden Anatomie, der Genetik usw. — Das Wirkliche in seiner Gesamthet hingegen besitzt keine systematische sondern nur eine historisch-dialektische Struktur. Metaphysisch bedeutet das, dass das Wesen der Wirklichkeit in schöpferischer Freiheit im Sinne etwaGoethes, aber nicht in sturer Notwendigkeit besteht.Se demuestra que — como en laFisica — tambien en la Biologia existen complementarios sistemas de conocimiento. Como onda y corpúsculo dentro de la Fisica, asi son dentro de la Biologia entre otros forma y función, mundo internoy ambientey en primer lugar también herencia y adaptación principios complementarios. Esto será discutido y demonstrado en sus particularidades.Para el conocimiento de la realidad como totalidad sigue de tales consideraciones la conclusión que conocimientos sistematicamente construidos son posibles solo en esferas particulares de la realidad — como p.e. en la mecánica racional, en la electrodinámica, en la anatomia comparada, en la genética etc. —. Lo real en su totalidad posee al contrario ninguna estructura sistemática sino solo un históricadialectica. Metafisicamente hablado significa esto que la esencia de la realidad consiste en una libertad creativa en el sentido deGoethe, pero de ninguna manera en una necesidad absoluta en el sentido deSpinoza.

by the question in its being an answer, if only in a circumstantial (i. e. inessential) manner. One indeed must question oneself in order to remember, says Plato, but the dialectic, which would be scientific, must be something else even if it remains a play of question and answer. This contradiction did not escape Aristotle: he split the scientific from the dialectic and logic from argumentation whose respective theories he was led to conceive in order to clearly define their boundaries (...) and specificities. As for Plato, he found in the famous theory of Ideas what he sought in order to justify knowledge as that which is supposed to hold its truth only from itself. What do Ideas mean within the framework of our approach? In what consists the passage from rhetoric to ontology which leads to the denaturation of argumentation? When Socrates asked, for example, "What is virtue?", he thought one could not answer such a question because the answer refers to a single proposition, a single truth, whereas the formulation of the question itself does not indicate this unicity. For any answer, another can be given and thus continuously, if necessary, until eventually one will come across an incompatibility. Now, to a question as to what X, Y, or Z is, one can answer in many ways and nothing in the question itself prohibits multiplicity. Virtue is courage, is justice, and so on. (shrink)

A so called “weak value” of an observable in quantum mechanics (QM) may be obtained in a weak measurement + post-selection procedure on the QM system under study. Applied to number operators, it has been invoked in revisiting some QM paradoxes (e.g., the so called Three-Box Paradox and Hardy’s Paradox). This requires the weak value to be interpreted as a bona fide property of the system considered, a par with entities like operator mean values and eigenvalues. I question such an (...) interpretation; it has no support in the basic axioms of quantum mechanics and it leads to unreasonable results in concrete situations. (shrink)

Let S be the set of all entities that exist (or have existed). Define the relation <= on S by saying that x<=y if and only y is a cause of x. By verbal fiat we will define x to be a cause of x for all x in S (if we do not accept this definition, our assumptions will be slightly different; however, it is clear that the existence of x is necessary and sufficient for the existence of x, (...) and that the existence of x is never strictly temporally posterior to that of x, so calling x a cause of itself is not such a bad idea.) Then, <= is transitive, and moreover if x<=y and y<=x, then x=y (i.e., there are no circles of causation). Hence, <= defines a partial ordering on S. (shrink)

Ben-Israel and Vaidman have raised objections to my arguments that there are cases where a quantum mechanical weak value can be said not to represent the system to which it pertains. They are correct in pointing out that some of my conclusions were too general. However, for weak values of projection operators my conclusions still stand.

The operational definition of a weak value for a quantum mechanical system involves the limit of the weak measurement strength tending to zero. I study how this limit compares to the situation for the undisturbed system. Under certain conditions, which I investigate, this limit is discontinuous in the sense that it does not merge smoothly to the Hilbert space description of the undisturbed system. Hence, in these discontinuous cases, the weak value does not represent the undisturbed system. As a result, (...) conclusions drawn from such weak values regarding the properties of the studied system cannot be upheld. Examples are given. (shrink)

Shoemaker (1996) presenteda prioriarguments against the possibility of ‘self‐blindness’, or the inability of someone, otherwise intelligent and possessed of mental concepts, to introspect any of her concurrent attitude states. Ironically enough, this seems to be a position that Gopnik (1993) and Carruthers (2006, 2008, 2009a,b) have proposed as not only possible, but as the actual human condition generally! According to this ‘Objectivist’ view, supposed introspection of one's attitudes is not ‘direct’, but an ‘inference’ of precisely the sort we make about (...) the attitudes of others, an inference that has the advantage in our own case ofonlyour own sensory data and memories, our behavior, and of the context we are in; i.e. we are all substantially self‐ blind. After sorting out a number of methodological and verbal issues, I argue, first, that thea prioriarguments against Objectivism don't succeed, and that Gopnik and Carruthers are right to regard the issue as an empirical one. On the other hand, I think they seriously underestimate the difficulty of establishing Objectivism. It is unlikely there is an inferential procedure from the data of pure sensation, behavior and context to the relevant self‐attributions that would be as spectacularly reliable as people manifestly seem to be. Moreover, there is a simpler model: the mind very likely consists of a panoply of sub‐routines some of whose outputs are ‘tagged’ for their having been so processed, rather in the way that software ‘documents’ are on standard computers. Introspection plausibly consists in a person's simply attending to distinctive constellations of these tags, even though they may lack phenomenal feels. This draws attention to an important independent fact: that much of phenomenology (or ‘what it's like’ to be in a certain state) may be constituted by facts that are not phenomenal. (shrink)

Quantum mechanical weak values of projection operators have been used to answer which-way questions, e.g. to trace which arms in a multiple Mach–Zehnder setup a particle may have traversed from a given initial to a prescribed final state. I show that this procedure might lead to logical inconsistencies in the sense that different methods used to answer composite questions, like “Has the particle traversed the way X or the way Y?”, may result in different answers depending on which methods are (...) used to find the answer. I illustrate the problem by considering some examples: the “quantum pigeonhole” framework of Aharonov et al., the three-box problem, and Hardy’s paradox. To prepare the ground for my main conclusion on the incompatibility in certain cases of weak values and logic, I study the corresponding situation for strong/projective measurements. In this case, no logical inconsistencies occur provided one is always careful in specifying exactly to which ensemble or sample space one refers. My results cast doubts on the utility of quantum weak values in treating cases like the examples mentioned. (shrink)

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor (...) evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.
