Talents that selectively facilitate the acquisition of high levels of skill are said to be present in some children but not others. The evidence for this includes biological correlates of specific abilities, certain rare abilities in autistic savants, and the seemingly spontaneous emergence of exceptional abilities in young children, but there is also contrary evidence indicating an absence of early precursors of high skill levels. An analysis of positive and negative evidence and arguments suggests that differences in early experiences, preferences, (...) opportunities, habits, training, and practice are the real determinants of excellence. Key Words: exceptional ability; expertise; gift; innate capacity; music; potential; prodigy; specific ability; talent. (shrink)

Current critical pedagogical scholarship has theorized the epistemological and social intersection between globalization and educational technology according to two distinct positions. For some, this intersection offers new liberatory knowledges and opportunities that can subvert social homogenization and economic disparity. For others, this relationship is just another phase of neoimperialism that should be politically and ideologically resisted. In contrast, we argue that the intersection between globalization and educational technologies is rather a manifestation of larger economic and logical forces, and that resistance (...) to such circumstances can neither be purely ideological or social. Instead, we contend that such a theoretical and pedagogical foreclosure dialectically actualizes conditions for real change—particularly when it complicates educational research technologies and their impact on epistemological multiplicity.

This article proposes an eclectic and holistic model of ethics and ethical thinking. It uses this tripart model to show how partialities can be integrated into impartial moral reasoning. Ethical reasoning is divided into three problem areas or "levels" - cases, frameworks, and ultimate ethical goals. Each level employs its own form of reasoning. For evaluating cases, the author advocates an eclectic application of principles; for evaluating frameworks of principles, the author advocates contractualism; for evaluating ethical theory as a whole, (...) the author advocates a notion of the human good inspired by Aristotelian perfectionism. This article argues that utilitarianism, which is one part of eclectic deliberation, is hampered by the idea that ethical reasoning must be based on a single moral criterion or "master" principle. The article concludes by showing how this eclectic model, supplemented by "mitigated impartialism," provides a systematic method for assessing partialities, with reference to the problem of patriotism in journalism.

Microtubules are protein cylinders with functions in cell motility, signal sensing, cell organization, intracellular transport, and chromosome segregation. One of the key properties of microtubules is their dynamic architecture, allowing them to grow and shrink in length by adding or removing copies of their basic subunit, the heterodimer αβ‐tubulin. In higher eukaryotes, de novo assembly of microtubules from αβ‐tubulin is initiated by a 2 MDa multi‐subunit complex, the gamma‐tubulin ring complex (γ‐TuRC). For many years, the structure of the γ‐TuRC and (...) the function of its subunits remained enigmatic, although structural data from the much simpler yeast counterpart, the γ‐tubulin small complex (γ‐TuSC), were available. Two recent breakthroughs in the field, high‐resolution structural analysis and recombinant reconstitution of the complex, have revolutionized our knowledge about the architecture and function of the γ‐TuRC and will form the basis for addressing outstanding questions about biogenesis and regulation of this essential microtubule organizer.

An article on the aspect of the League which most concerns the present study is Larsen, "Representative Government in the Panhellenic Leagues," CP 20..

Basado enteramente en pruebas internas, este estudio se propone mostrar que el manuscrito único del Dīwān de Ibn Quzmān, publicado en edición facsímil por David de Gunzburg en 1896, es una copia dictada. Se indica también que el copista, a quien con frecuencia se ha culpado de introducir en el texto popular andaluz correcciones o clasicismos, no estaba bien equipado para desempeñar tal papel. Si bien era un calígrafo de primera categoría, se aducen pruebas de que su conocimiento del árabe (...) no estaba a la altura de la calidad de su caligrafía. El estudio muestra que él fue el responsable de una amplia gama de problemas textuales que ha dejado perplejos a sucesivos editores del Dīwān. En marcado contraste, se muestra que Ibn Quzmān poseía un dominio magistral de la lengua árabe y de las tradiciones-árabes clásicas. Al parecer también había adquirido un alto grado de 'aculturación' en la lengua romance. Además de ofrecer las pruebas en que se basan estos asertos, el estudio constituye un ejemplo ilustrativo de cómo estas pruebas pueden ayudar a una mejor lectura e interpretación del Dīwān de Ibn Quzmān.

In our target article, we presented the idea that involuntary autobiographical memories (IAMs) and déjà vu may both be based on the same retrieval processes. Our core claim was thus straightforward: Both can be described as “involuntary” or spontaneous cognitions, where IAMs deliver content and déjà vu delivers only the feeling of retrieval. Our proposal resulted in 27 commentaries covering a broad range of perspectives and approaches. The majority of them have not only amplified our key arguments but also pushed (...) our ideas further by offering extensions, refinements, discussing possible implications and providing additional empirical, neuroscientific and clinical support. The discussion launched by the commentaries proves to us the importance of bringing IAMs and déjà vu into mainstream discussions of memory retrieval processes. (shrink)
