Communication as a Teaching/Learning Strategy in Bilingual Education
This paper is based on my experience as a member of the coordinating team of the Plurilingual Education Programme (PEP) at the School of Education, Universidad de Cadiz (Spain). We have been working with a group of 23 subject-matter teachers belonging to up to 13 content areas and three target languages: English, French and German. The main purpose of the project was to train lectures on the CLIL (Content and Language Integrated Learning) methodological approach. We have focused our training on content and communication (based on Coyle (1999)’s four C’s framework) with an emphasis on constructing the communicative channels appropriate to convey content with language as a medium of communication, not as an aim itself. As communicative exchanges will be between non-native teachers and non-native students, teachers have been trained on some communicative strategies typical of the CLIL approach in order to improve the teachers’ communicative competence. In this paper, some of these strategies and their benefits will be depicted : using the foreign language as the language of communication in the class, improving clarity of speech, enhancing oral interaction with/among students, visual aids, rephrasing, reformulating, redundancy or content reduction are amongst the most essential strategies to improve communicative exchanges in bilingual settings
Augmented Perception for Agricultural Robots Navigation
[EN] Producing food in a sustainable way is becoming very challenging today due to the lack of skilled labor, the unaffordable costs of labor when available, and the limited returns for growers as a result of low produce prices demanded by big supermarket chains in contrast to ever-increasing costs of inputs such as fuel, chemicals, seeds, or water. Robotics emerges as a technological advance that can counterweight some of these challenges, mainly in industrialized countries. However, the deployment of autonomous machines in open environments exposed to uncertainty and harsh ambient conditions poses an important defiance to reliability and safety. Consequently, a deep parametrization of the working environment in real time is necessary to achieve autonomous navigation. This article proposes a navigation strategy for guiding a robot along vineyard rows for field monitoring. Given that global positioning cannot be granted permanently in any vineyard, the strategy is based on local perception, and results from fusing three complementary technologies: 3D vision, lidar, and ultrasonics. Several perception-based navigation algorithms were developed between 2015 and 2019. After their comparison in real environments and conditions, results showed that the augmented perception derived from combining these three technologies provides a consistent basis for outlining the intelligent behavior of agricultural robots operating within orchards.This work was supported by the European Union Research and Innovation Programs under Grant N. 737669 and Grant N. 610953.

Sensing Architecture for Terrestrial Crop Monitoring: Harvesting Data as an Asset
[EN] Very often, the root of problems found to produce food sustainably, as well as the origin of
many environmental issues, derive from making decisions with unreliable or inexistent data. Datadriven
agriculture has emerged as a way to palliate the lack of meaningful information when taking
critical steps in the field. However, many decisive parameters still require manual measurements
and proximity to the target, which results in the typical undersampling that impedes statistical
significance and the application of AI techniques that rely on massive data. To invert this trend, and
simultaneously combine crop proximity with massive sampling, a sensing architecture for automating
crop scouting from ground vehicles is proposed. At present, there are no clear guidelines of how
monitoring vehicles must be configured for optimally tracking crop parameters at high resolution.
This paper structures the architecture for such vehicles in four subsystems, examines the most
common components for each subsystem, and delves into their interactions for an efficient delivery
of high-density field data from initial acquisition to final recommendation. Its main advantages
rest on the real time generation of crop maps that blend the global positioning of canopy location,
some of their agronomical traits, and the precise monitoring of the ambient conditions surrounding
such canopies. As a use case, the envisioned architecture was embodied in an autonomous robot to
automatically sort two harvesting zones of a commercial vineyard to produce two wines of dissimilar
characteristics. The information contained in the maps delivered by the robot may help growers
systematically apply differential harvesting, evidencing the suitability of the proposed architecture
for massive monitoring and subsequent data-driven actuation. While many crop parameters still
cannot be measured non-invasively, the availability of novel sensors is continually growing; to benefit
from them, an efficient and trustable sensing architecture becomes indispensable.This research was funded by the European Union's Horizon 2020 research and innovation program with grant agreement number 737669 entitled VineScout: Intelligent decisions from vineyard robots.Rovira Más, F.; Saiz Rubio, V.; Cuenca-Cuenca, A.

Un ideólogo olvidado: el joven José Antonio Maravall y la defensa del Estado Nacionalsindicalista. Su colaboración en Arriba, órgano oficial de FET y de las JONS. 1939-1941
Remembered as a liberal man, brilliant pioneer in investigation of the social history of mentalities, José Antonio Maravall was, nevertheless, one of the main teachers and moving forces of the post war falangism. This is to say, of the Falangist project supported by the power of Ramón Serrano Súñer as the brother in law of Francisco Franco and as the Minister of Government and Overseas Affairs. A project which Maravall himself identifed with the European totalitarian movement represented, essentially, by Nazi Germany and which he defended as the best option for social and political reconstruction of the Spain resulting from the civil war
Actitudes de los docentes hacia el papel de la lengua en la educación bilingüe en la universidad
The main goal of this article is to explore the attitudes (opinions, beliefs, etc.)
regarding ‘language’ of university teachers engaged in bilingual education. The context for
this research is an on-going teacher development programme at the School of Engineering
(Escuela Superior de Ingeniería) at the University of Cadiz. At this stage in our research,
we are looking at teacher attitudes to language from three perspectives: to better understand
what they think about language in their ‘normal’ i.e. Spanish/monolingual teaching; how they
conceive of language per se in learning and how they feel about bilingual classrooms. Prior
to their involvement in bilingual education, these teachers were likely encouraged to think
of themselves as specialists in Áreas No Lingüísticas, but it would appear that they are in
the process of reconceptualising both the roles of language in learning and the contributions
that teachers can make. In the bilingual classrooms, most of their students are locals with
limited language skills and the teachers favour an approach geared to developing both
content and languages (L1 and L2) concurrently and perceive of themselves as both models
and facilitators in the process. We interpret this as a good example of Internationalization at
Home (IaH).El objetivo principal de este artículo es esbozar las actitudes (opiniones,
creencias, etc.) respecto a la lengua del profesorado universitario participante en planes
de enseñanza bilingüe. El contexto de esta investigación es un programa de formación
permanente de docentes en la Escuela Superior de Ingeniería de la Universidad de
Cádiz. En esta etapa de nuestra investigación, hemos analizado las actitudes de los
docentes hacia el lenguaje desde tres perspectivas diferentes. Por un lado, comprender
mejor lo que piensan sobre la lengua en su enseñanza “normal”, es decir, español /
monolingüe. Por otro lado, cómo conciben el papel de la lengua en sí en el proceso de
aprendizaje. Por último, cuál es su opinión acerca de la enseñanza bilingüe. Antes de
su participación en el programa de enseñanza bilingüe, estos docentes se consideraban a sí mismos especialistas en áreas no lingüísticas, pero tras un período extenso de
formación, parecen inmersos en el proceso de re-conceptualización tanto del papel de
la lengua en el aprendizaje como de las aportaciones que ellos mismos pueden hacer
desde esta nueva perspectiva didáctica. En la clase bilingüe, la mayoría son estudiantes
locales con capacidades lingüísticas limitadas, de ahí que la labor de los docentes se
base en un enfoque orientado al desarrollo integrado de contenidos y lenguas (L1 y L2),
y se perciban a sí mismos como modelos y facilitadores en el proceso de aprendizaje.
Este es un buen ejemplo de internacionalización en casa
Study of the establishment of epithelial polarity: search for new proteins that interact with apkc
Póster presentado al IX Meeting of the Spanish Society for Developmental Biology celebrado en Granada del 12 al 14 de noviembre de 2012.A key issue in developmental
biology is the relationship
between cell polarity and
signal transduction pathways.
Most eukaryotic cells
are polarized with an
asymmetric distribution
of molecules and organelles
resulting in different
functional regions required
for cell physiology. The control
of this polarity in space and
time is essential to coordinate
changes in cell morphology
with proliferation and
morphogenetic movements
required for the development
of the organism. This control
is carried out by signalling pathways, which in many
cases are regulated by the
subcellular localization of
their components. In fact,
there is a close relationship
between polarity and the
control of cell proliferation,
since many receptors of
intercellular communication
pathways that regulate proliferation are located and
activated in specific domains
of the plasma membrane.
Therefore, the understanding
of the signalling pathways‐cell
polarity relationship is crucial
for the knowledge of how
signals are integrated to
induce morphogenesis but
also how are modified in
aberrant processes as
those occurring in cancer.
The atypical protein kinase
C (aPKC) is a crucial protein
in the cell polarity
establishment or maintenance
and also can participate in
many other processes in
the cell. aPKC has an
enzymatic activity and
can regulate different
signaling pathways in the cell. In
all these processes aPKC
interact, depending on the
process, with different regulators
and modifies different substrates.
In addition, aPKC is an
oncogene. To understand
how cell polarity is established,
maintained and modified and
also how this polarity can regulate
signalling processes we have
focused on to find out new
proteins that interact with
aPKC.Peer Reviewe

Las funciones del personal eventual en la jurisprudencia
Aquest estudi analitza de manera exhaustiva la jurisprudència dels tribunals contenciosos administratius sobre les funcions de confiança i assessorament del personal eventual que la llei els encomana, sense concretar en què consisteixen. Aquesta indefinició ha generat nombrosos conflictes i litigis, aguditzats per la crisi econòmica. La Llei 27/2013, de racionalització i sostenibilitat de l'Administració local, estableix límits al nombre de llocs de personal eventual, segons la població del municipi, però no n’aborda la definició de les funcions. Per la qual cosa, la jurisprudència, que aquest treball sistematitza amb sentit crític, continua sent l'única orientació sobre aquest tema.This study is a comprehensive analysis of the case law of the administrative litigation courts relating to the responsibilities of trust and specialist advice that the law gives temporary staff, albeit without offering a clear definition of the nature of their functions. This legal and regulatory grey area has caused many conflicts and legal disputes made worse by the economic crisis. Act 27/2013 on Rationalization and Sustainability of Local Administration establishes a limit to the number of temporary staff according to the number of inhabitants in each municipality, but does not tackle the question of the definition of their functions. Consequently, the case law which this work systematises from a critical perspective, offers the only guidance on the subject to date.Este estudio analiza de manera exhaustiva la jurisprudencia de los tribunales de lo contencioso-administrativo sobre las funciones de confianza y asesoramiento del personal eventual, que la ley les encomienda sin concretar en qué consisten.
