Alguns aspectes formals de la traducció llatina de l'Alcorà de Robert de Ketton (ca. 1141-1143) i la seva relació amb el text original àrab

En el marc de la història de la transmissió escrita de l'Alcorà (al-Qur'an), l'article fa referència a l'evolució de la forma i l'estructura del text en relació amb l'oralitat del missatge original, a l'existència de diferents tradicions textuals en el si de la comunitat islàmica i al seu reflex en les traduccions. L'atenció se centra, sobretot, en la primera traducció sencera coneguda de l'Alcorà al llatí, realitzada per Robert de Ketton (ca. 1141-1143) a la Vall de l'Ebre, i se'n destaca el valor documental com a testimoni contemporani d'una tradició magribina i andalusina de tractament del text.

Sobre l'aplicació de les transformacions en una gramàtica generativa i transformacional

Gramática aplicada a ELE: la perífrasis “ir a + infinitivo” y el futuro sintético

La presencia en español de dos construcciones —la perífrasis «IR A+Infinitivo» y lasformas verbales sintéticas terminadas en –rá— que pueden alternarse en determinadoscontextos como mecanismos para expresar la futuridad en español ha llevado a unageneralización en el uso de tales construcciones descuidando la vertiente pragmática delas mismas, y, en consecuencia, se ha tendido a ofrecer al estudiante de ELE unaconsideración básicamente gramatical de los usos de la perífrasis y del futuro sintético. Eneste sentido, el objetivo de nuestra propuesta busca establecer las principales divergencias de carácter pragmático que —creemos— deberían incorporarse a la explicación de estos contenidos gramaticales.

Intracellular membrane trafficking in Osteoclasts The role of direct Rab protein – Rac 1 interactions in the targeting of intracellular vesicles

Osteoclasts are cells responsible for bone resorption. These cells undergo extensive membrane re-organization during their polarization for bone resorption and form four distinct membrane domains, namely the ruffled border, the basolateral membrane, the sealing zone and the functional secretory domain. The endocytic/biosynthetic pathway and transcytotic route(s) are important for the resorption process, since the endocytic/biosynthetic pathway brings the specific vesicles to the ruffled border whereas the transcytotic flow is believed to transport the degraded bone matrix away from the resorption lacuna to the functional secretory domain. In the present study, we found a new transcytotic route from the functional secretory domain to the ruffled border, which may compensate membrane loss from the ruffled border during the resorption process. We also found that lipid rafts are essential for the ruffled border-targeted late endosomal pathways. A small GTP-binding protein, Rab7, has earlier been shown to regulate the late steps of the endocytic pathway. In bone-resorbing osteoclasts it is involved in the formation of the ruffled border, which displays several features of late endosomal membranes. Here we discovered a new Rab7-interacting protein, Rac1, which is another small GTP-binding protein and binds to the GTP-form of Rab7 in vitro. We demonstrated further that Rab7 colocalizes with Rac1 at the fusion zone of the ruffled border in bone-resorbing osteoclasts. In other cell types, such as fibroblast-like cells, this colocalization is mainly perinuclear. Because Rac1 is known to control the actin cytoskeleton through its effectors, we suggest that the Rab7-Rac1 interaction may mediate late endosomal transport between microtubules and microfilaments, thus enabling endosomal vesicles to switch tracks from microtubules to microfilaments before their fusion to the ruffled border. We then studied the role of Rab-Rac1 interaction in the slow recycling pathway. We revealed that Rac1 also binds directly to Rab11 and to some other but not all Rab-proteins, suggesting that Rab-Rac1 interaction could be a general regulatory mechanism to direct the intracellular vesicles from microtubule mediated transport to actin filament mediated transport and vice versa. On the basis of our results we thus propose a new hypothesis for these GTPases in the regulation of intracellular membrane flow.

Aprendizaje léxico y desarrollo de la gramática: vocabulario verbal, aceleración morfológica y complejidad sintáctica

This paper studies the initial development of certain language components. More precisely, we analyse the relation between three aspects that are closely involved in the grammar of the verb: morphological productivity, syntactic complexity, and verb vocabulary learning. The study is based on data about the relationship between lexical development and grammatical development, and also on proposals that a critical mass of vocabulary is needed in order to develop a grammatical component. The sample comprised six subjects who are monolingual or bilingual in Catalan andlor Spanish. Results show a morphological spurt some time afer the learning of a certain quantity of verbs. Moreover, syntactic complexity is only evident some months after this morphological spurt

The Progress and Challenges of the e-Government Initiatives and Implementation in the Kurdistan Region of Iraq

The Electronic Government (e-Government) means delivering the services and information to the citizens and businesses through the use of Information and Communication Technology (ICT) in order to enable them to interact more effectively with the government, and to increase the quality of the services. As many other governments in the developed and developing countries, the Kurdistan Regional Government (KRG) has embarked on the e-Government initiatives. This study revealed that there are various challenges which affect the e-Government in the Kurdistan Region of Iraq (KRI), but also a lot of e-Government progress has happened. In addition, based on the United Nations’ e-Government maturity level benchmarking, the e-Government in the KRI is at the interactive stage. In this study the services that the citizens want from the government in order to implement an appropriate e-Government were also identified.

O Compêndio de Gramática Hebraica de Espinosa é uma obra more geometrico demonstrata?

No prefácio das Obras póstumas de Espinosa, o inacabado Compêndio de gramática da língua hebraica é apresentado como um trabalho que, segundo a intenção do autor, quando concluída, assumiria a forma de uma exposição more geometrico da gramática hebraica. Nos estudos espinosanos, muitas vezes se buscou determinar o aspecto geométrico do trabalho, sobretudo em comparação com a Ética, ou então renegá-lo, afirmando a incongruência de aplicar-se tal método a um objeto, um idioma, inapreensível à geometria. A partir da reconsideração desses argumentos e do estudo de algumas passagens do Compêndio, acreditamos ser possível concluir que a obra era realmente redigida como uma exposição geométrica da gramática hebraica, o que se revela especialmente pela presença de um movimento ordenado e dedutivo a comandar sua composição.
