Defining typologies of universities through a DEA-MDS analysis: An institutional characterization for formative evaluation purposes
Universities are organizational structures with individual activity mixes or strategies that lead to different performance levels by mission. Evaluation techniques based on performance indicators or rankings risk rewarding just a specific type of university and undermining university diversification: They usually introduce homogenizing pressures and risk displacing university objectives- neglecting their socio-economic contribution and focusing on succeeding on the evaluation system. In this study, we propose an alternative evaluation method that overcomes these limitations. We produce a multidimensional descriptive classification of universities into typologies, while analysing the relation between their institutional factors (characteristics) and their (technical) efficiency performance from a descriptive perspective. To do so we apply bootstrap data envelopment analysis (DEA) and multidimensional scaling analysis (MDS), performing a so-called DEAMDS analysis on data on the Spanish university system, and unlike previous studies, we include data on an important dimension of the third mission of universities (specifically knowledge transfer, KT) in their characterization. We identify six types of (homogeneous) universities. Results indicate that to be fairly efficient, universities may focus on teaching, KT, or overall efficiency but always have to fairly perform in research. Additionally, results confirm the relevance of the third mission as a source of institutional diversity in higher education. This approach could be used to address an alternative evaluation methodology for higher education institutions with formative purposes, evaluating universities according to their unique characteristics for the improvement of HE system
La utilidad de lo inutilizado. El patrimonio socio-cultural en la formación del profesorado de educación infantil: un aula para el naufragio pedagógico
Este trabajo presenta el sustento teórico, y una propuesta formativa para el alumnado de Grado de la Facultad de Ciencias de la Educación. Por ello, la creación de un Aula Experimental de Patrimonio Socio-Cultural integrada en la Facultad, asume una mirada interdisciplinar, donde la vinculación entre historia, patrimonio y disciplinacientíficaabren un nuevo camino de reflexión en el campo pedagógico y curricular. La disciplina en la que se enmarca este proyecto, referenciado por la Didáctica de las Ciencias Sociales, parte de una organización epistemológica, para que, este nuevo tratamiento del patrimonio contenga el peso académico que se merece, y siga siendo una fuente de conocimiento social.En el presente trabajo de Fin de Máster se lleva a cabo una revisión teórica y fundamentada sobre la inclusión del patrimonio en la Educación Infantil, una detallada exposición de su evolución, la protección legal que contiene actualmente y cuál es su origen como valor social. No obstante, se realiza un examen crítico del currículo educativo, y del patrimonio como fuente de trabajo en Educación Infantil.This work presents the theoretical background, and a training proposal for the undergraduate students of the Faculty of Education Sciences. For this reason, the creation of an Experimental Classroom of Socio-Cultural Heritage integrated in the Faculty, take on an interdisciplinary perspective, where the link between history, heritage and scientific disciplineopens a new path of reflection in the pedagogical and curricular field. The discipline in which this project is framed, referenced by the Didactics of Social Sciences, is part of an epistemological organization, so that this new treatment of heritage contains the academic weight it deserves, and continues to be a source of social knowledge.In this Final Master's thesis, a theoretical and substantive review is carried out on the inclusion of heritage in Early Childhood Education, a detailed exposition of its evolution, the legal protection it currently contains and what its origin is as a social value. However, there is a critical examination of the educational curriculum and heritage as a source of work in Early Childhood Education
A Review of Sensor Technologies for Perception in Automated Driving
After more than 20 years of research, ADAS are
common in modern vehicles available in the market. Automated
Driving systems, still in research phase and limited in their
capabilities, are starting early commercial tests in public roads.
These systems rely on the information provided by on-board
sensors, which allow to describe the state of the vehicle, its
environment and other actors. Selection and arrangement of
sensors represent a key factor in the design of the system. This
survey reviews existing, novel and upcoming sensor technologies,
applied to common perception tasks for ADAS and Automated
Driving. They are put in context making a historical review of
the most relevant demonstrations on Automated Driving, focused
on their sensing setup. Finally, the article presents a snapshot of
the future challenges for sensing technologies and perception,
finishing with an overview of the commercial initiatives and
manufacturers alliances that will show future market trends in
sensors technologies for Automated Vehicles.This work has been partly supported by ECSEL Project ENABLE-

Structural Insights into the HWE Histidine Kinase Family: The Brucella Blue Light-Activated Histidine Kinase Domain
In response to light, as part of a two-component system, the Brucella blue light-activated histidine kinase (LOV-HK) increases its autophosphorylation, modulating the virulence of this microorganism. The Brucella histidine kinase (HK) domain belongs to the HWE family, for which there is no structural information. The HWE family is exclusively present in proteobacteria and usually coupled to a wide diversity of light sensor domains. This work reports the crystal structure of the Brucella HK domain, which presents two different dimeric assemblies in the asymmetric unit: one similar to the already described canonical parallel homodimers (C) and the other, an antiparallel non-canonical (NC) dimer, each with distinct relative subdomain orientations and dimerization interfaces. Contrary to these crystallographic structures and unlike other HKs, in solution, the Brucella HK domain is monomeric and still active, showing an astonishing instability of the dimeric interface. Despite this instability, using cross-linking experiments, we show that the C dimer is the functionally relevant species. Mutational analysis demonstrates that the autophosphorylation activity occurs in cis. The different relative subdomain orientations observed for the NC and C states highlight the large conformational flexibility of the HK domain. Through the analysis of these alternative conformations by means of molecular dynamics simulations, we also propose a catalytic mechanism for Brucella LOV-HK.Fil: Rinaldi, Jimena Julieta.

Pigs naturally exposed to porcine circovirus type 2 (PCV2) generate antibody responses capable to neutralise PCV2 isolates of different genotypes and geographic origins
Porcine circovirus type 2 (PCV2) is the essential infectious agent for PCV2-systemic disease (PCV2-SD, formerly known as postweaning multisystemic wasting syndrome) and other pathological conditions. Recent studies indicated antigenic variability amongst different PCV2 isolates and suggested that single amino acid changes within the capsid protein determine differences in the level of neutralization by specific monoclonal antibodies. The objective of the present study was to examine the cross-reactivity of PCV2 antibodies induced in the context of a natural infection against different PCV2 isolates belonging to genotypes PCV2a and PCV2b. Sera taken from several farms from animals of varying health status (PCV2-SD and age-matched healthy pigs and a set of slaughter-aged animals) were assayed for neutralizing activity against four PCV2 isolates from both predominant genotypes (PCV2a and PCV2b) and of differing geographic origins (Europe and North-America). Results showed that most of studied pigs (79 out of 82) contained neutralizing antibodies (NA) able to neutralize all four studied viral strains. Overall, pigs had significantly higher NA titres against PCV2a than against PCV2b (P< 0.001). Accordingly, studied serums were able to better neutralize Burgos390L4 and Stoon-1010 strains (PCV2a) than L-33-Sp-10-54 and MO/S-06 strains (PCV2b) (P< 0.001). No differences between capabilities of seroneutralization of viruses from different geographic origin were observed. Present data suggests that sequence differences between PCV2 isolates translate to functional antigenic differences in viral neutralization in vivo
Totally Laparoscopic Roux-en-Y Duct-to-Mucosa Pancreaticojejunostomy After Middle Pancreatectomy A Consecutive Nine-case Series at a Single Institution
To present the results of a series of laparoscopic middle
pancreatectomies with roux-en-Y duct-to-mucosa pancreaticojejunostomy. SUMMARY OF
BACKGROUND DATA: Middle pancreatectomy makes it possible to preserve pancreatic
parenchyma in the resection of lesions that traditionally have been treated by
distal splenopancreatectomy or cephalic duodenopancreatectomy. The laparoscopic
approach could minimize the invasiveness of the procedure and enhance the
benefits of middle pancreatectomy. METHODS: From March 2005 to October 2007, 9
consecutive patients with benign or low malignant potential lesions in the
pancreatic neck or body underwent surgery. Laparoscopic middle pancreatectomy
with a roux-en-Y duct-to-mucosa pancreaticojejunostomy was planned on all of
them. In the first 2 patients, the pancreas was transected by endostapler; in the
last 7, the staple line was reinforced with absorbable polymer membrane. RESULTS:
The intervention was concluded laparoscopically in every case except 1
(laparoscopic-assisted) in which pancreaticojejunostomy was performed by means of
minilaparotomy. Mortality was 0% and perioperative morbidity was 33%, (fistula of
the cephalic stump in the first 2 patients (22%)). The pancreaticojejunostomy
fistula rate was 0%. The median postoperative hospital stay was 5 days (range,
3-41). In the last 7 patients, in which pancreas was transected with staple line
reinforcement material there were no stump fistulas; morbidity decreased to 14%
and the median hospital stay was 4 days (range, 3-30). CONCLUSIONS: Laparoscopic
middle pancreatectomy is feasible and safe. Duct-to-mucosa pancreaticojejunostomy
can be performed safely using this approach. The method of pancreatic transection
seems to be decisive in the incidence of cephalic stump fistulas
Cirugía laparoscópica hepática y pancreática
The development of laparoscopic surgery also
includes the more complex procedures of abdominal
surgery such as those that affect the liver and the
pancreas. From diagnostic laparoscopy, accompanied
by laparoscopic echography, to major hepatic or
pancreatic resections, the laparoscopic approach has
spread and today encompasses practically all of the
surgical procedures in hepatopancreatic pathology.
Without forgetting that the aim of minimally invasive
surgery is not a better aesthetic result but the
reduction of postoperative complications, it is
undeniable that the laparoscopic approach has
brought great benefits for the patient in every type of
surgery except, for the time being, in the case of big
resections such as left or right hepatectomy or
resections of segments VII and VIII.
Pancreatic surgery has undergone a great
development with laparoscopy, especially in the field
of distal pancreatectomy due to cystic and
neuroendocrine tumours where the approach of choice
is laparoscopic. Laparoscopy similarly plays an
important role, together with echolaparoscopy, in
staging pancreatic tumours, prior to open surgery or
for indicating suitable treatment.
In coming years, it is to be hoped that it will
continue to undergo an exponential development and,
together with the advances in robotics, it will be
possible to witness a greater impact of the
laparoscopic approach on the field of hepatic and
pancreatic surgery
