Comparative Analysis Of Learning Outcomes In Face-To-Face Foreign Language Classes Vs. Language Lab And Online
Action research was conducted for two consecutive semesters comparing beginning level Spanish courses taught in the traditional classroom and the same class taught exclusively in the language lab. A subsequent semester compared an intermediate class taught in the traditional classroom compared to the same class conducted online. Assessment scores were compared for quizzes, tests, oral interview and final exam. Overall course GPA and student opinions were also compared. Identical treatments showed the classroom performed significantly better than the lab class yet the following semester showed the lab performing better but not at a significant level. A second study compared a higher level of students for classroom vs. online. This study showed the classroom performance was better in three out of four assessments, however this difference was not significant
The Effects Of Songs In The Foreign Language Classroom On Text Recall, Delayed Text Recall And Involuntary Mental Rehearsal
Music represents an integral part of the human culture, and particularly language and communication. Music can be a powerful tool in the learning experience. The purpose of the present study is to investigate whether English native-speaker students learning a foreign language can benefit from integrating music into the curriculum. Students’ text recall was measured after listening to songs and text passages. Delayed recall and involuntary mental rehearsal (din) were also measured. Results showed text recall was better in the song condition that text passage. Also, treatment condition did not affect delayed recall; however it impacted involuntary mental rehearsal. Implications and suggestions about future applications of music in the curriculum are also explored
Jerusalén. La ciudad y la palabra en la obra de Jacques Derrida
In this article we may try to track down the use
and the presence of Jerusalem in Jacques Derrida works.
Between the real city and the word that designates it, the
jerusalemite topic rises in Derrida’s writing as a bazillionth
symptom of a self-confessed obsession. The Jewishness
of the father of Deconstruction is one of the
most decisive signs in his relationship with texts and
words and, in the case of the thrice holy city it serves to
explain one of the speech acts that perhaps he more committed
with. Promise, as well as forgiveness and confession,
is a paradoxical speech act where its conditions of
possibility turn into impossible. Far from any calling related
to truth or falseness, the city and the word, the town
and the concept, will serve us to follow some of the most
decisive trail in the biography and the work of one of the
most outstanding thinkers of our philosophical traditio
The animal that does not speak: disability and the limits of the human
En el presente artículo tratamos de exponer el modo en que algunas premisas éticoontológicas
implícitas en la Declaración Universal de los Derechos Humanos han
imposibilitado la construcción de discursos morales verdaderamente inclusivos con
respecto a la discapacidad. Así, defenderemos que gran parte del reto filosófico de pensar la
discapacidad debe pasar necesariamente por la revisión de algunas premisas generales que a
través de su paulatina asimilación histórica han terminado por desdibujarse en el debate
ético y político. Por ello, en este artículo trataremos de evidenciar las insuficiencias
conceptuales tradicionales para enfrentar moralmente la realidad de la discapacidad
psíquica y plantearemos a modo de hipótesis algunos presupuestos desde los cuales
esperamos reconstruir una moralidad eficazmente inclusiva con aquellas personas que
padecen algún tipo de discapacidadIn this paper we aim to expose how some tacitly-assumed ontological and ethical
premises in The Universal Declaration of Human Rights have historically hindered the
construction of moral paradigms inclusive with disability. We therefore argue that a central
part of this philosophical challenge must be the exposure and revision of these general
premises, which have been blurred by historical assimilation yet are nevertheless important
in ordinary ethical and political debates. This paper will try to highlight the deficiency of
our traditional concepts when we try to face this problem from an ethical point of view. We
will then try to propound some other conceptual categories so as to set up an inclusive,
efficient and satisfactory moral theory for intellectual disabilit
Hermenéutica y existencia en el Cuarto Evangelio
En el presente artículo tratamos de justificar la presencia de una hermenéutica existencial
en uno de los textos fundacionales de nuestra tradición: el Prólogo del Evangelio de Juan. Para ello,
planteamos una interpretación crítica de las traducciones clásicas de dicho texto e intentamos defender
que la escatología joánica no atiende a un emplazamiento cronológico sino a otro preferentemente
espacial. A lo largo de nuestro estudio examinaremos el uso y la traducción de las preposiciones en
el Prólogo y la Carta Primera para subrayar la función sígnico-existencial de la Encarnación del Hijo. A
partir de esta hipótesis, reconstruiremos una interpretación a través de la cual el Prólogo del Evangelio
de Juan puede y debe interpretarse como un precedente remoto y fundacional de una de los marcos
filosóficos más relevantes del siglo xx: la hermenéutica de la existenciaIn this paper we aim to justify the presence of an existencial hermeneutics in one of the
foundational texts of Christian, or Judeo-Christian tradition: the Prologue to the Gospel of John. To
this end, we raise a critic interpretation of the classical translations of the text and try to verify that the
Saint John’s eschatology does not meet a chronological emplacement but a spatial one. Throughout
this work we examine the use of prepositions in the Prologue and the First Letter in order to remark
the signifying and existential function of the Incarnation Starting from this hypothesis we aim to defend
that the Prologue to the Gospel of John states a foundational, albeit chronologically distant, precedent
of one of the most relevant philosophical frameworks in the 20th century continental philosophy: the
hermeneutics of existenc
The cosmological tree theorem
A number of diagrammatic “cutting rules” have recently been developed for the wavefunction of the Universe which determines cosmological correlation functions. These leverage perturbative unitarity to relate particular “discontinuities” in Feynman-Witten diagrams (with cosmological boundary conditions) to simpler diagrams, in much the same way that the Cutkosky rules relate different scattering amplitudes. In this work, we make use of a further causality condition to derive new cutting rules for Feynman-Witten diagrams on any time-dependent spacetime background. These lead to the cosmological analogue of Feynman’s tree theorem for amplitudes, which can be used to systematically expand any loop diagram in terms of (momentum integrals of) tree-level diagrams. As an application of these new rules, we show that certain singularities in the wavefunction cannot appear in equal-time correlators due to a cancellation between “real” and “virtual” contributions that closely parallels the KLN theorem. Finally, when combined with the Bunch-Davies condition that certain unphysical singularities are absent, these cutting rules completely determine any tree-level exchange diagram in terms of simpler contact diagrams. Altogether, these results remove the need to ever perform nested time integrals when computing cosmological correlators

On Passion and Desire: Confronting an Ambiguity in Aristotle’s Ethics
One of the most relevant topics in the Aristotelian moral philosophy for contemporary ethics is the reflection about emotional motivation and the link established between emotions and moral virtue. The Aristotelian vocabulary, that said, is unfortunately quite unclear as to that respect. In this paper, we will try to outline a taxonomy of the emotional lexicon in order to set up the semantic borders between desire and passions. Having established these limits, we may advance some of the most relevant features without which we would not be able to interpret correctly the Aristotelian theory of action and his conception of virtue. In order to attain this goal we will examine the motivational role of passions, the epistemological implications of desire and the occasional relation of synonymy between these notions.Uno de los asuntos de la filosofía moral de Aristóteles que tiene más relevancia para la ética contemporánea es la reflexión sobre la motivación emocional, así como sobre el vínculo que se establece entre las emociones y la excelencia moral. El vocabulario aristotélico, por decirlo de alguna manera, es desgraciadamente algo ambiguo en este punto. En este trabajo, trataremos de desarrollar una taxonomía del léxico emocional aristotélico para así poder establecer las fronteras semánticas entre deseo y pasiones. Una vez establecidos dichos límites, podremos proponer algunos de los rasgos más sobresalientes sin los cuales no sería posible interpretar correctamente la teoría aristotélica de la acción ni su concepción de la excelencia. Para conseguir dicho objetivo, examinaremos el rol motivacional de las pasiones, las implicaciones epistemológicas del deseo y la relación ocasional de sinonimia entre estas dos nociones
Exploring cloudy gas accretion as a source of interstellar turbulence in the outskirts of disks
High--resolution 2D--MHD numerical simulations have been carried out to
investigate the effects of continuing infall of clumpy gas in extended HI
galactic disks. Given a certain accretion rate, the response of the disk
depends on its surface gas density and temperature. For Galactic conditions at
a galactocentric distance of ~20 kpc, and for mass accretion rates consistent
with current empirical and theoretical determinations in the Milky Way, the
rain of compact high velocity clouds onto the disk can maintain transonic
turbulent motions in the warm phase (~2500 K) of HI. Hence, the HI line width
is expected to be ~6.5 km/s for a gas layer at 2500 K, if infall were the only
mechanism of driving turbulence. Some statistical properties of the resulting
forcing flow are shown in this Letter. The radial dependence of the gas
velocity dispersion is also discussed.Comment: 13 pages, 3 figures, accepted for publication in ApJ Letter
