Dueling Nationalities: Dual Citizenship, Dominant and Effective Nationality, and the Case of Anwar al-Aulaqi

This Comment argues that when hearing a case involving a suspected terrorist who holds dual citizenship, a domestic court should first determine, as a threshold matter, the dominant and effective nationality of the accused. This determination is significant because a dominant foreign national can essentially be treated as a non-citizen, for the purposes of adjudication, and may not be entitled to the full rights and protections of domestic citizenship

Relación del temperamento y estilos de aprendizaje en los estudiantes de derecho de la Universidad Nacional de Tumbes

Evidentemente el abordar el tema de la personalidad y los estilos de aprendizaje en las últimas décadas, es un nuevo rumbo para el proceso de aprendizaje, con el propósito de mejorar la calidad educativa. La personalidad, es un sistema único, que involucra nuestra peculiar forma de pensar, sentir y actuar; comprendiendo, en consecuencia, los procesos psicológicos cognitivos, afectivos y volitivo motivacionales, es de tipo genético con una base biológica, donde la herencia es el factor determinante para actuar para el proceso de aprendizaje. Por otro lado los estilos de aprendizaje se refieren a los estudiantes que perciben y adquieren conocimiento de manera distinta, tienen ideas, piensan, y actúan de forma diferente. Podemos afirmar que es la manera de un estudiante que comienza a concentrarse sobre una información nueva, la trata y la retiene con sus propios estilos de aprendizaje. En la práctica pedagógica se observa que los estudiantes poseen diferentes tipos de temperamentos, con diferentes estilos de aprendizaje que se evidencia en su forma de procesar la información, por que encontramos estudiantes que poseen habilidades para analizar, resumir, e interpretar

Zeolite-dye micro lasers

We present a new class of micro lasers based on nanoporous molecular sieve host-guest systems. Organic dye guest molecules of 1-Ethyl-4-(4-(p-Dimethylaminophenyl)-1,3-butadienyl)-pyridinium Perchlorat were inserted into the 0.73-nm-wide channel pores of a zeolite AlPO$_4$-5 host. The zeolitic micro crystal compounds where hydrothermally synthesized according to a particular host-guest chemical process. The dye molecules are found not only to be aligned along the host channel axis, but to be oriented as well. Single mode laser emission at 687 nm was obtained from a whispering gallery mode oscillating in a 8-$\mu$m-diameter monolithic micro resonator, in which the field is confined by total internal reflection at the natural hexagonal boundaries inside the zeolitic microcrystals.Comment: Accepted for publication in Phys.

Autler-Townes splitting in two-color photoassociation of 6Li

We report on high-resolution two-color photoassociation spectroscopy in the triplet system of magneto-optically trapped 6Li. The absolute transition frequencies have been measured. Strong optical coupling of the bound molecular states has been observed as Autler-Townes splitting in the photoassociation signal. The spontaneous bound-bound transition rate is determined and the molecule formation rate is estimated. The observed lineshapes are in good agreement with the theoretical model.Comment: 5 pages, 4 figures, accepted for publication in Phys. Rev. A (Rapid Communication

Untersuchungen zum Gehalt an ME und praecaecal verdaulichen Aminosäuren aus einem Gemisch thermisch behandelter Körnerleguminosen (LEGUMI-therm®) beim Broiler

The objective of this study was to assess the effect of heating a mixture of grain legumes based on sweet lupins, faba beans, and peas (1:1:1, toasted “LEGUMItherm ®”; untreated: “LEGUMI-mix”) on the content of metabolisable energy (ME) and precaecal digestible (pc) amino acids for broilers. The mean of amino acid digestibility of LEGUMI-mix and LEGUMI-therm was 88 and 87 %. The ME content of the mixture ranged between 11.9 (LEGUMI-therm) and 12.1 MJ/kg DM (LEGUMI-mix). Both parameters were unaffected by heating

Issues and Concerns in Implementing Quality Circles in Public School Management in Nigeria

Quality improvement in educational institutions in Nigeria and the world at large is a major concern. Countries all over the world are therefore making concerted efforts towards the improvement of educational standards. One of the management techniques applied in most of these countries especially Japan, Britain and America is the Quality Control circles. Its application in Nigeria raises a lot of concerns. These concerns and issues bother on the structure, techniques; methods; and reactions of management of the institutions in implementing the recommendations of quality circles. These and many other issues and concerns form the major crux of this paper. The paper concludes that inspite of these issues and concerns; Quality circle is a technique that will assist in the achievement of educational goals Keywords: Issues and concerns, Implementing, Public Schools and Management

The ultrafilter number for singular cardinals

We prove the consistency of a singular cardinal $\lambda$ with small value of the ultrafilter number $u_\lambda$, and arbitrarily large value of $2^\lambda$.Comment: 8 page

Detecting the Earliest Galaxies Through Two New Sources of 21cm Fluctuations

The first galaxies that formed at a redshift ~20-30 emitted continuum photons with energies between the Lyman-alpha and Lyman limit wavelengths of hydrogen, to which the neutral universe was transparent except at the Lyman-series resonances. As these photons redshifted or scattered into the Lyman-alpha resonance they coupled the spin temperature of the 21cm transition of hydrogen to the gas temperature, allowing it to deviate from the microwave background temperature. We show that the fluctuations in the radiation emitted by the first galaxies produced strong fluctuations in the 21cm flux before the Lyman-alpha coupling became saturated. The fluctuations were caused by biased inhomogeneities in the density of galaxies, along with Poisson fluctuations in the number of galaxies. Observing the power-spectra of these two sources would probe the number density of the earliest galaxies and the typical mass of their host dark matter halos. The enhanced amplitude of the 21cm fluctuations from the era of Lyman-alpha coupling improves considerably the practical prospects for their detection.Comment: 11 pages, 7 figures, ApJ, published.

Deep far infrared ISOPHOT survey in "Selected Area 57", I. Observations and source counts

We present here the results of a deep survey in a 0.4 sq.deg. blank field in Selected Area 57 conducted with the ISOPHOT instrument aboard ESAs Infrared Space Observatory (ISO) at both 60 um and 90 um. The resulting sky maps have a spatial resolution of 15 x 23 sq.arcsec. per pixel which is much higher than the 90 x 90 sq.arcsec. pixels of the IRAS All Sky Survey. We describe the main instrumental effects encountered in our data, outline our data reduction and analysis scheme and present astrometry and photometry of the detected point sources. With a formal signal to noise ratio of 6.75 we have source detection limits of 90 mJy at 60 um and 50 mJy at 90 um. To these limits we find cumulated number densities of 5+-3.5 per sq.deg. at 60 um and 14.8+-5.0 per sq.deg.at 90 um. These number densities of sources are found to be lower than previously reported results from ISO but the data do not allow us to discriminate between no-evolution scenarios and various evolutionary models.Comment: 15 pages, 11 figures, accepted by Astronomy & Astrophysic
