Spanish validation of the locus of control questionnaire in sport for children

El locus de control ha sido estudiado en el deporte, sin embargo no existía un instrumento válido para evaluarlo en deporte infantil. Este estudio lleva a cabo la validación española del Children´s Sport Locus of Control Scale (CSLCS) que desarrollaron Tsai y Hsieh (2015). La adaptación presenta dos fases: una primera exploratoria con 248 niños entre 7 y 16 años para observar el comportamiento cualitativo de los ítems; y una segunda con 221 deportistas entre 8 y 22 años en la que se modificó el cuestionario para ajustarlo a los resultados obtenidos. Se obtiene una escala final de 10 ítems, con 5 ítems por dimensión (interna y externa), que presenta un ajuste adecuado. Los resultados demuestran que la versión española de la escala posee cualidades psicométricas adecuadas para ser utilizada en la investigación y la práctica aplicada en la evaluación deportiva infantilLocus of control has been studied in the sport context, however there was no valid instrument to evaluate it in children's sport. This study adapts into Spanish and validates the Children's Locus of Control Scale for Sport (CSLCS) in the Spanish language. This CSLCS was developed by Tsai y Hsieh (2015). The adaptation has two phases: an initial screening of 248 children between the ages of 7 and 16 to observe the qualitative behavior of the items; and a second one with 221 athletes with children between the ages of 8 and 22 in which the questionnaire was modified to fit the results. A final 10-item scale was obtained, with 5 items per dimension (internal and external), which presents an adequate fit. Results show that the Spanish version of the scale possesses adequate psychometric qualities for its use in research and applied fields in child´s sport evaluatio

The Charitable Deduction and Looting of Antiquities: A Comparative Approach

The tax incentive structure for charitable giving in the United States, as in many other countries, is imperfect. The structure over-incentivizes donations from wealthy individuals, whether those donations are made up of cash or of property. This structure has negative impacts not only domestically, but abroad as well. By providing an incentive for donations of antiquities to museums— an incentive that was perhaps largely necessitated by the state of American museums in the 19th century— the charitable deduction has not only created a market for antiquities of questionable provenance, but has also created what is potentially a get-out-of-jail free card for those who knowingly purchase antiquities of questionable provenance or fail to conduct their due diligence in determining whether an antiquity’s provenance is genuine. The international community has largely condemned the looting of archaeological sites and the sale of unprovenanced antiquities. Regardless of whether one subscribes to cultural property nationalism or internationalism, incentivizing the looting of these sites through the tax system is a problem that must be remedied

Metacinnabar ({\beta}-HgS): a strong 3D topological insulator with highly anisotropic surface states

We establish the presence of topologically protected edge states on the (001) surface of HgS in the zinc-blende structure using density-functional electronic structure calculations. The Dirac point of the edge state cone is very close to the bulk valence band maximum. The Dirac cone is extremely anisotropic with a very large electron velocity along one diagonal of the surface elementary cell x' and a nearly flat dispersion in the perpendicular direction y'. The strong anisotropy originates from a broken fourfold rotoinversion symmetry at the surface.Comment: Phys. Rev. Lett., in pres

Diagnosis of Inter-Turn Short Circuit for a Polyphase Induction Motor in Closed-Loop Vector-Controlled Drives

The main objective of this paper is to develop and experimentally verify a new technique to detect an inter-turn short circuit in one phase of a stator winding of an induction motor energized from a vector-controlled drive. This is in order to overcome the fault masking difficulties associated with the concept of depending on the actual magnetic field pendulous oscillation between the conventional voltage and current space vectors with respect to a reference that is unaltered by the compensation action of the drive. This technique is based on the flux pendulous oscillation phenomenon. This flux pendulous oscillation is also described in this paper, this in addition to the magnetic field pendulous oscillation previously addressed in prior publications. The new approach has been verified through experimental results which are represented here

Round Complexity in the Local Transformations of Quantum and Classical States

A natural operational paradigm for distributed quantum and classical information processing involves local operations coordinated by multiple rounds of public communication. In this paper we consider the minimum number of communication rounds needed to perform the locality-constrained task of entanglement transformation and the analogous classical task of secrecy manipulation. Specifically we address whether bipartite mixed entanglement can always be converted into pure entanglement or whether unsecure classical correlations can always be transformed into secret shared randomness using local operations and a bounded number of communication exchanges. Our main contribution in this paper is an explicit construction of quantum and classical state transformations which, for any given $r$, can be achieved using $r$ rounds of classical communication exchanges but no fewer. Our results reveal that highly complex communication protocols are indeed necessary to fully harness the information-theoretic resources contained in general quantum and classical states. The major technical contribution of this manuscript lies in proving lower bounds for the required number of communication exchanges using the notion of common information and various lemmas built upon it. We propose a classical analog to the Schmidt rank of a bipartite quantum state which we call the secrecy rank, and we show that it is a monotone under stochastic local classical operations.Comment: Submitted to QIP 2017.

Comments on 'Protecting Consumer Privacy in an Era of Rapid Change: A Proposed Framework for Businesses and Policymakers'

The purpose of this document is to respond to selected questions for comment on the proposed framework in the FTC report 'Protecting Consumer Privacy in an Era of Rapid Change: A Proposed Framework for Businesses and Policymakers' (December 1st, 2010). Our responses are based on our ongoing research about online privacy and data risk at NYU Stern School's Center for Digital Economy Research. Our findings are described further in Dhar, Hsieh and Sundararajan (2011).NYU Stern School of Busines
