Implantació d'una plataforma informàtica en una entitat financera fusionada

Els darrers anys han estat molt convulsos en el món financer. De tots és coneguda la crisi, immobiliària en un primer moment, i financera més tard. Reestructuracions, fusions, absorcions, intervencions i nacionalitzacions han estat a l’ordre del dia en el món de les entitats financeres els últims 3 anys. El mapa financer ha passat de més de 50 entitats a poc menys de 10 en tan sols 3 anys. Els departaments de tecnologia de bancs i caixes no han estat aliens a aquests moviments. Tot i estar relativament al marge del negoci financer de l’entitat, cada fusió ha atorgat un paper protagonista a tota la plantilla informàtica. Ja que cada reestructuració ha suposat un gran esforç per integrar entitats molt diferents entre si en una de sola. Intentant que l’impacte a clients i a usuaris fos el menor possible. Caixa Manlleu és un exemple proper de la reestructuració del món financer, i ha protagonitzat, juntament amb Caixa Sabadell i Caixa Terrassa, la creació d’Unnim. Aquest cas real serà la base del treball. El projecte consisteix en la creació d’una plataforma informàtica per a la nova entitat resultant de la fusió. Una plataforma amb un doble objectiu: d’una banda, que reculli el millor de les tres plataformes d’origen i que compleixi tots els requestis que la nova entitat exigeix per tal que els usuaris puguin continuar fent les tasques diàries. I de l’altra, una plataforma que posi al dia i actualitzi tecnològicament l’entitat amb el mínim cost possible. Així doncs, cal analitzar per separat cadascuna de les 3 plataformes existents, inventariar les aplicacions comunes i les departamentals, així com les llicències de software vigents existents i no caducades. Decidir quines aplicacions es faran servir, si se’n poden aprofitar o si per contra en calen de noves. També cal analitzar quins equips informàtics (terminals) es necessitaran per tal de treure el màxim rendiment de la plataforma. Entre les conclusions obtingudes en el projecte, cal destacar els grans avantatges d’utilitzar aplicacions virtualitzades en lloc de les tradicionals aplicacions instal·lades físicament a cada terminal. Faciliten la feina i el manteniment, estalvien recursos i fan guanyar temps. A més a més s’aconsegueix una plataforma àgil, lleugera i ràpida.

Estressors i ansietat en els cuidatges pal·liatius: Una proposta de canvi en el pla d'estudis d'Infermeria

Néixer, créixer, madurar, envellir i morir, són les etapes que travessa l’ésser humà al llarg de la seva vida, però no necessàriament s’ha d’envellir per arribar a la mort. Hi ha persones que la vida biològica s’acaba abans de la mort. Són els pacients terminals. Per tenir cura dels malalts al final de la seva vida, s’implanten els cuidatges pal·liatius. A partir d’aquests cuidatges, es proporciona una atenció global, activa i continuada als pacients i als seus familiars, amb l’objectiu de millorar la qualitat de vida i cobrir totes les necessitats d’aquests pacients.

Increased anandamide induced relaxation in mesenteric arteries of cirrhotic rats. Role of cannabinoid and vanilloid receptors

Background and aims: Anandamide is an endocannabinoid that evokes hypotension by interaction with peripheral cannabinoid CB1 receptors and with the perivascular transient receptor potential vanilloid type 1 protein (TRPV1). As anandamide has been implicated in the vasodilated state in advanced cirrhosis, the study investigated whether the mesenteric bed from cirrhotic rats has an altered and selective vasodilator response to anandamide. Methods: We assessed vascular sensitivity to anandamide, mRNA and protein expression of cannabinoid CB1 receptor and TRPV1 receptor, and the topographical distribution of cannabinoid CB1 receptors in resistance mesenteric arteries of cirrhotic and control rats. Results: Mesenteric vessels of cirrhotic animals displayed greater sensitivity to anandamide than control vessels. This vasodilator response was reverted by CB1 or TRPV1 receptor blockade, but not after endothelium denudation or nitric oxide inhibition. Anandamide had no effect on distal femoral arteries. CB1 and TRPV1 receptor protein was higher in cirrhotic than in control vessels. Neither CB1 mRNA nor protein was detected in femoral arteries. Immunochemistry showed that CB1 receptors were mainly in the adventitia and in the endothelial monolayer, with higher expression observed in vessels of cirrhotic rats than in controls. Conclusions: These results indicate that anandamide is a selective splanchnic vasodilator in cirrhosis which predominantly acts via interaction with two different types of receptors, CB1 and TRPV1 receptors, which are mainly located in perivascular sensory nerve terminals of the mesenteric resistance arteries of these animals.

Prognostic value of cortically induced motor evoked activity by TMS in chronic stroke: caveats from a very revealing single clinical case

Background: We report the case of a chronic stroke patient (62 months after injury) showing total absence of motor activity evoked by transcranial magnetic stimulation (TMS) of spared regions of the left motor cortex, but near-to-complete recovery of motor abilities in the affected hand. Case presentation: Multimodal investigations included detailed TMS based motor mapping, motor evoked potentials (MEP), and Cortical Silent period (CSP) as well as functional magnetic resonance imaging (fMRI) of motor activity, MRI based lesion analysis and Diffusion Tensor Imaging (DTI) Tractography of corticospinal tract (CST). Anatomical analysis revealed a left hemisphere subinsular lesion interrupting the descending left CST at the level of the internal capsule. The absence of MEPs after intense TMS pulses to the ipsilesional M1, and the reversible suppression of ongoing electromyographic (EMG) activity (indexed by CSP) demonstrate a weak modulation of subcortical systems by the ipsilesional left frontal cortex, but an inability to induce efficient descending volleys from those cortical locations to right hand and forearm muscles. Functional MRI recordings under grasping and finger tapping patterns involving the affected hand showed slight signs of subcortical recruitment, as compared to the unaffected hand and hemisphere, as well as the expected cortical activations. Conclusions: The potential sources of motor voluntary activity for the affected hand in absence of MEPs are discussed. We conclude that multimodal analysis may contribute to a more accurate prognosis of stroke patients.

Técnicas de Anonimato para Securizar Redes Móviles Ad Hoc

Las redes móviles ad hoc son redes formadas por lainterconexión de terminales inalámbricos que de manera autónoma,sin ninguna administración central, establecen enlaces decomunicación entre ellos. La infraestructura de red la componenlos propios terminales de usuarios que actúan de gestores yencaminadores de paquetes. Así, un usuario cualquiera puedeconectarse con un terminal remoto a través de una conexiónmultisalto entre diferentes usuarios. En este tipo de redes tanabiertas, uno de los retos prioritarios es proteger el anonimatode los sujetos y sus localizaciones. En este artículo hacemos unrepaso de las técnicas existentes a través de los protocolos que sehan propuesto en la literatura, y exponemos los problemas queaun quedan abiertos.

The IST METRA Project

This article summarizes the main achievementsof the Multi-Element Transmit andReceive Antennas (METRA) Project, an ISTresearch and technological development project carried out between January 2000 and June 2001 by Universitat Politècnica de Catalunya, the Center for Personkommunikation of Aalborg University, Nokia Networks, Nokia Mobile Phones, and Vodafone Group Research and Development.The main objective of METRA was the performanceevaluation of multi-antenna terminals incombination with adaptive antennas at the basestation in UMTS communication systems. 1 AMIMO channel sounder was developed that providedrealistic multi-antenna channel measurements.Using these measured data, stochasticchannel models were developed and properly validated.These models were also evaluated inorder to estimate their corresponding channelcapacity. Different MIMO configurations andprocessing schemes were developed for both theFDD and TDD modes of UTRA, and their linkperformance was assessed. Performance evaluationwas completed by system simulations thatillustrated the benefits of MIMO configurationsto the network operator. Implementation cost vs.performance improvement was also covered bythe project, including the base station and terminalmanufacturer and network operator viewpoints.Finally, significant standards contributionswere generated by the project and presented to the pertinent 3GPP working groups.

Hybrid turbo FEC/ARQ systems and distributed space-time coding for cooperative transmission

Cooperative transmission can be seen as a "virtual" MIMO system, where themultiple transmit antennas are in fact implemented distributed by the antennas both at the source and the relay terminal. Depending on the system design, diversity/multiplexing gainsare achievable. This design involves the definition of the type of retransmission (incrementalredundancy, repetition coding), the design of the distributed space-time codes, the errorcorrecting scheme, the operation of the relay (decode&forward or amplify&forward) and thenumber of antennas at each terminal. Proposed schemes are evaluated in different conditionsin combination with forward error correcting codes (FEC), both for linear and near-optimum(sphere decoder) receivers, for its possible implementation in downlink high speed packetservices of cellular networks. Results show the benefits of coded cooperation over directtransmission in terms of increased throughput. It is shown that multiplexing gains areobserved even if the mobile station features a single antenna, provided that cell wide reuse of the relay radio resource is possible.

Signaling across the synapse: a role for Wnt and Dishevelled in presynaptic assembly and neurotransmitter release

Proper dialogue between presynaptic neurons and their targets is essential for correct synaptic assembly and function. At central synapses, Wnt proteins function as retrograde signals to regulate axon remodeling and the accumulation of presynaptic proteins. Loss of Wnt7a function leads to defects in the localization of presynaptic markers and in the morphology of the presynaptic axons. We show that loss of function of Dishevelled-1 (Dvl1) mimics and enhances the Wnt7a phenotype in the cerebellum. Although active zones appear normal, electrophysiological recordings in cerebellar slices from Wnt7a/Dvl1 double mutant mice reveal a defect in neurotransmitter release at mossy fi ber–granule cell synapses. Deficiency in Dvl1 decreases, whereas exposure to Wnt increases, synaptic vesicle recycling in mossy fi bers. Dvl increases the number of Bassoon clusters, and like other components of the Wnt pathway, it localizes to synaptic sites. These fi ndings demonstrate that Wnts signal across the synapse on Dvl-expressing presynaptic terminals to regulate synaptic assembly and suggest a potential novel function for Wnts in neurotransmitter release.

Les arts plàstiques com a cura pal·liativa a l'etapa final de la vida

Aquest projecte pretén fer una proposta d’intervenció d’arts plàstiques a unitats de cures pal·liatives amb malalts terminals. Per tal d’acompanyar la dimensió espiritual de la persona que està passant per un procés de final de la seva pròpia vida. Sobretot s’ha creat un discurs a través de molta recerca i investigació, el qual es pot adequar a la importància de la incorporació de l’educador social a l’equip multidisciplinari d’aquestes unitats hospitalàries. L’objectiu principal és afavorir una millor qualitat de vida, retrobar-se amb el sentit de la vida, poder reconciliar-se i acomiadar-se a través de les obres plàstiques. Tal i com diu la pel·lícula “El intocable” (2013): “¿Porque la gente se interesa por el arte? – Porque es la única huella de nuestro paso por LaTierra.”

Application of the N-alkane molecular alloys to thermally protected containers for catering

A thermally controlled transport device was designed and tested. As hot food needs to be transported at temperatures between 60 and 70ºC in order to avoid contamination by microorganisms, the use of Molecular Alloy Phase Change Materials (MAPCM) can lead to improvements in this field of application. A heat transfer numerical simulation of the box used for transporting the food was conducted. Despite obvious simplifications, a good agreement between numerical simulation and experimental results was obtained. Furthermore, we compared our experimental results with those from other experiments related to the transport of hot food. Here, pizza is taken as the example, and it is shown that delivering time can be increased three-fold.

La seva vocació va sorgir quan una nena li cridava 'mare' mentre l'abraçava, en aquell moment va decidir iniciar el seu generós projecte d'ajuda als altres sense límits

Transmedia Storytelling: Implicit Consumers, Narrative Worlds, and Branding in Contemporary Media Production

Many concepts have been developed to describe the convergence of media, languages, and formats in contemporary media systems. This article is a theoretical reflection on “transmedia storytelling” from a perspective that integrates semiotics and narratology in the context of media studies. After dealing with the conceptual chaos around transmedia storytelling, the article analyzes how these new multimodal narrative structures create different implicit consumers and construct a narrative world. The analysis includes a description of the multimedia textual structure created around the Fox television series 24. Finally, the article analyzes transmedia storytelling from the perspective of a semiotics of branding.

Aprendizagem baseada em Jogos Digitais Entrevistas com professores que utilizam jogos digitais em suas práticas educativas

In contrast to other media like TV or cinema, digital games are unique and different because they offer a persuasive rhetoric. This investigation introduces the cases of two primary school teachers who use digital games as one of their teaching methods. Both cases are multimodal and show the teacher’s position in education. This work also explores the challenges faced by teachers as instructors, and the application of digital games in modern classes.From an ethnographic view, gathering information techniques are used, such as documentary analysis and interviews in order to collect data about each case with two teachers from the province of Barcelona. The obtained results raise important questions: what is the main role of a teacher using digital games in class, how teachers participate in learning based on digital games and how digital games are developed and combined with other teaching methodologies. The conclusions obtained by this research let us understand the reason why using digital games in class allows the students to learn and keep their motivation: digital games stimulate them so they can establish a personal connection.

Botulinum neurotoxin type A blocks the morphological changes induced by chemical stimulation on the presynaptic membrane of Torpedo synaptosomes.

The action of botulinum neurotoxin on acetylcholine release, and on the structural changes at the presynaptic membrane associated with the transmitter release,was studied by using a subcellular fraction of cholinergic nerve terminals (synaptosomes) isolated from the Torpedo electric organ. Acetylcholine and ATP release were continuously monitored by chemiluminescent methods.To catch the membrane morphological changes, the quick-freezing method was applied. Our results show that botulinum neurotoxin inhibits the release of acetylcholine from these isolated nerve terminals in a dose-dependent manner, whereas ATP release is not affected. The maximal inhibition (70%) is achieved at neurotoxin concentrations as low as 125 pM with an incubation time of 6 min. This effect is not linked to an alteration of the integrity of the synaptosomes since, after poisoning by botulinum neurotoxin type A, they show a nonmodified occluded lactate dehydrogenase activity. Moreover, membrane potential is not altered by the toxin with respect to the control, either in resting condition or after potassium depolarization. In addition to acetylcholine release inhibition, botulinum neurotoxin blocks the rearrangement of the presynaptic intramembrane particles induced by potassium stimulation. The action of botulinum neurotoxin suggests that the intramembrane particle rearrangement is related to the acetylcholine secretion induced by potassium stimulation in synaptosomes isolated from the electric organ of Torpedo marmorata.
