Micropropagation and cryopreservation by vitrification of the Spanish endemic medicinal plant Sideritis leucantha Cav. subsp. leucantha (Lamiaceae)
No full textSideritis leucantha Cav. subsp. leucantha is a Spanish endemic medicinal plant that faces conservation problems. Therefore, this
work is aimed to develop a protocol for the in vitro propagation and cryopreservation of shoot tip explants of this species. The
morphogenic responses were recorded using Murashige and Skoog medium containing 6-benzyladenine, 2-isopentenyladenine,
kinetin, or thidiazuron for multiplication and 1-naphthaleneacetic acid or indole-3-butyric acid for rooting. Maximal shoot
proliferation was observed with medium containing 0.088 M sucrose plus 0.22 or 0.44 μM 6-benzyladenine. The longest shoots
and greatest number of nodes per shoot were obtained from cultures incubated on medium with 0.44 μM 2-isopentenyladenine.
Optimal rooting was achieved with 1-naphthaleneacetic acid at concentrations of 0.05 μM (highest percentage of rooted shoots)
and 0.26 μM (highest number of roots). The morphological traits of the regenerated plantlets did not differ from those of wildtype plants, and these plantlets were successfully adapted to ex vitro conditions. After cryopreservation by vitrification, the
highest percentage of regenerated shoot tips (70 ± 6%) was obtained with the treatment consisting of 60 min of loading solution
(0.4 M sucrose plus 2 M glycerol in liquid medium) followed by exposure to plant vitrification solution 2 for 30 min at room
temperature and then immersion in liquid nitrogen for 60 min. This study constitutes the first work on the micropropagation of
S. leucantha subsp. leucantha and the first work on the cryopreservation of Sideritis species. The results obtained could be
applied commercially and also in the conservation for other species of Lamiaceae.This work has been supported by Generalitat Valenciana, Project GV04B-459. J.E.R.L. was awarded a grant from University of Alicante.Ciencias Experimentale
Virtual simulation in teacher education across borders
No full textThere is already an abundant literature on the virtues of simulation in education. However, there is also a lack of assessment instruments to determine the impact of virtual simulation and virtual exchange on participants’ self-realisation of learning in teacher education. The aim of this study is to identify the variables that best describe students’ learning of current educational issues. A questionnaire consisting of Likert-type items was used as a metacognitive assessment tool to provide data for the study. An exploratory longitudinal study was conducted over three years. Data were collected using students’ answers to the questionnaire. A convenience sampling procedure was used, with participating students enrolled in the Didactic Resources module of English as a Second Language (ESL) in an Official Master’s Degree in Teacher Training in Compulsory Secondary Education and Baccalaureate, Vocational Training, and Language Teaching. The most strongly correlated variables that best explain the dependent variable (“I have gained deeper insights into current educational issues”) addressed inclusion, special learning needs, service learning, and simulation through intercultural dialogue. Each of the variables significantly contributes to the estimation of perceived acquisition of insight into current educational issues through virtual simulation.Educació
Salbutamol transport and deposition in healthy cat airways under different breathing conditions and particle sizes
Get PDFSalbutamol is a bronchodilatator commonly used for the treatment of feline
inflammatory lower airway disease, including asthma or acute bronchospasm. As
in humans, a pressurized metered dose inhaler (pMDI) is used in conjunction with
a spacer and a spherical mask to facilitate salbutamol administration. However,
efficacy of inhalation therapy is influenced by different factors including the noncooperative character of cats. In this study, the goal was to use computational
fluid dynamics (CFD) to analyze the impact of breathing patterns and salbutamol
particle size on overall drug transport and deposition using a specific spherical
mask and spacer designed for cats. A model incorporating three-dimensional cat
airway geometry, a commercially available spherical mask, and a 10 cm spacer,
was used for CFD analysis. Two peak inspiratory flows were tested: 30 mL/s and
126 mL/s. Simulations were performed with 30s breathing different inspiratory
and expiratory times, respiratory frequencies and peaks. Droplet spray transport
and deposition were simulated with different particle sizes typical of the drug
delivery therapies (1, 5, 10, and 15 μm). The percentage of particle deposition
into the device and upper airways decreased with increasing particle diameter
during both flows imposed in this cat model. During increased mean ventilatory
rate (MVR) conditions, most of the salbutamol was lost in the upper airways. And
during decreased MVR conditions, most of the particles remained in suspension
(still in hold-up) between the mask and the carina, indicating the need for more
than 30 s to be transported. In both flows the percentage of particles traveling
to the lung was low at 1.5%–2.3%. In conclusion, in contrast to what has been
described in the human literature, the results from this feline model suggest
that the percentage of particles deposited on the upper airway decreases with
increasing particle diameter.This study is supported by grants PID2021-125731OB-C31 and PID2021-125731OB-C33 from the Spanish Ministry of Science and Innovation MCIN/AEI/10.13039/501100011033/ and FEDER (“A way to build Europe”).Veterinari
An approach to totalitarianism and its foundations, from the perspective of Hannah Arendt as part of the SHOA teaching in the context of secondary education
Get PDFEn la Shoah podemos ver cómo los eventos superan a las causas. Un origen que
se le ha denominado Totalitarismo, donde se traspasa todo límite conocido hasta el momento.
Un antisemitismo que produce unas herramientas de Mal no conocidas hasta el momento. Es
por esto que el docente encontrará en el artículo los datos para poder ver la génesis del término
y más que eso las consecuencias que se desatan en la producción de un nuevo sistema político
donde dará legalidad mediante la “solución final” al exterminio del pueblo judío. En el artículo
se puede ver cómo hay un cambio de sociedad para llegar a un nuevo hombre genéticamente
superior, el ario. El judío, el gitano, el comunista, el homosexual, es su contratipo, su enemigo,
hay que eliminarlos. Para ello se emplean una serie de herramientas como: El partido único
donde sólo tiene cabida aquellos que entran en la idea de sociedad, los demás no forman parte
de la nación. Se empleará la propaganda como cauce de verdad única que emana del partido
único. La policía secreta será la encargada de hacer cumplir estos principios, una policía que
sospecha de todos los individuos como enemigos del partido. El campo de concentración
será el laboratorio social para poder cambiar al ser humano y convertirlo en animal carente
de espontaneidad.In the Shoah we can see how events surpass causes. An origin that has been called
Totalitarianism, which exceeds all known limits so far. An anti-Semitism that produces some
tools of Evil not known up to now. This is why the teacher will find in the article the data to
be able to see the genesis of the term and more than that the consequences that are unleashed
in the production of a new political system where it will give legality with the Final Solution
to the extermination of the Jewish People. In the articles you can see how there is a change of
society to reach a new genetically superior man, the Aryan. The Jew, the gypsy, the communist,
the homosexual, is his counterpart, his enemy, they must be eliminated. For this, a series
of tools are used, such as: The single party where there is only room for those who enter into
the idea of society, the others are not part of the nation. Propaganda will be used as a channel
of the only truth that emanates from the single party. The secret police will be in charge of
enforcing these principles, a police that suspects all individuals as enemies of the party. The
concentration camp will be the social laboratory to be able to change the human being and
turn it into an animal devoid of spontaneity.Educació
The holocaust, an ethical and educative
Get PDFEl Holocausto es uno de los hechos históricos más importante del siglo XX. La puesta en marcha a partir de 1933 de las políticas raciales del Partido Nazi llevó a la marginación y exclusión de diversos colectivos, cuyas vidas eran consideradas sin valor. El inicio de la II Guerra Mundial en 1939 marcó el comienzo del asesinato planificado y médicamente supervisado de personas con discapacidad física o psíquica. Entre 1933 y 1945 seis millones de judíos fueron asesinados. Hubo otras víctimas como gitanos, homosexuales, testigos de Jehová, prisioneros políticos y, en general, todos los considerados “asociales”, que no encajaban en el ideal racial nazi. Para llevar a cabo este programa de limpieza racial, el Partido Nazi contó con la participación activa de médicos y personal sanitario. Durante la guerra se llevan a cabo experimentos con prisioneros de los campos principalmente con fines militares. Lo aprendido acerca de las acciones de los médicos y otros sanitarios durante el nazismo permite la reflexión sobre aspectos éticos relacionados no sólo con la forma de llevar a cabo la investigación, sino también con el deber de atender a todas las personas con independencia de su estado de salud, situación social, económica, religiosa, cultural, etc. La formación de todos los futuros profesionales en una sociedad plural ha de incorporar materias transversales en las que se aborde el respeto a la diversidad. El análisis del periodo nazi sirve como ejemplo de conductas que deben ser evitadasThe Holocaust is one of the most important historical events of the twentieth
century. The implementation from 1933 of the racial policies of the Nazi Party led to the
marginalization and exclusion of various groups, whose lives were considered worthless.
The outbreak of World War II in 1939 marked the beginning of the planned and medically
supervised murder of people with physical or mental disabilities. Between 1933 and 1945 six
million Jews were murdered. There were other victims such as Gypsies, homosexuals, Jehovah's
Witnesses, political prisoners and, in general, all those considered "asocial", who did
not fit into the Nazi racial ideal. To carry out this program of racial cleansing, the Nazi Party
had the active participation of doctors and health personnel. During the war experiments are
carried out on prisoners of the camps mainly for military purposes. What has been learned
about the actions of doctors and other health workers during Nazism allows reflection on
ethical aspects related not only to the way of carrying out research, but also to the duty to care
for all people regardless of their state of health, social, economic, religious, cultural situation,
etc. The training of all future professionals in a plural society must incorporate transversal
subjects in which respect for diversity is addressed. The analysis of the Nazi period serves as
an example of behaviors that should be avoided.Educació
Propuesta para la prevención de la frustración a través de la expresión emocional
Get PDFLa educación actual necesita un enfoque diferente, el cual se centre por igual en la enseñanza de las áreas académicas, así como en la educación emocional, ya que las escuelas actuales no ofrecen la atención necesaria a factores tan importantes como la frustración, los problemas en la expresión emocional o la dificultad en la regulación de las emociones por parte del alumnado.
Por ello, en el presente Trabajo de final de Grado se ofrecerá un análisis de los conceptos de frustración, educación emocional e inteligencia emocional, teniendo en cuenta las principales teorías en torno a la inteligencia emocional con el objetivo de conocer el valor del autoconcepto y la motivación dentro del aprendizaje. Además, se realizará un análisis del desarrollo emocional del alumnado, de los factores que producen frustración en el aprendizaje, de los principales perfiles familiares y su influencia, del clima del aula y de las características de los docentes.
Por otro lado, se elaborará una propuesta de intervención anual que promueve un seguimiento pautado del alumnado mediante objetivos y técnicas de organización para la prevención de la frustración, tanto académica como personal mediante una agenda emocional. Al mismo tiempo y con el objetivo de distinguir conductas emocionales de riesgo, la siguiente propuesta contiene un apartado de regulación emocional y de organización de aula, así como una metodología semanal basada en asambleas para tratar las emociones y las técnicas de regulación y expresión. Por último, la propuesta de intervención ha sido adaptada en torno a la legislación actual.L'educació actual necessita un enfocament diferent, el qual se centre per igual en l'ensenyament de les àrees acadèmiques, així com en l'educació emocional, ja que les escoles actuals no ofereixen l'atenció necessària a factors tan importants com la frustració, els problemes en l'expressió emocional o la dificultat en la regulació de les emocions per part de l'alumnat.
Per això, en el present Treball de final de Grau s'oferirà una anàlisi dels conceptes de frustració, educació emocional i intel·ligència emocional, tenint en compte les principals teories entorn de la intel·ligència emocional amb l'objectiu de conéixer el valor de l'autoconcepte i la motivació dins de l'aprenentatge. A més, es realitzarà una anàlisi del desenvolupament emocional de l'alumnat, dels factors que produeixen frustració en l'aprenentatge, dels principals perfils familiars i la seua influència, del clima de l'aula i de les característiques dels docents.
D'altra banda, s'elaborarà una proposta d'intervenció anual per promoure un seguiment pautat de l'alumnat mitjançant objectius i tècniques d'organització per a la prevenció de la frustració, tant acadèmica com personal amb l´ajuda d´una agenda emocional. Al mateix temps i amb la finalitat de distingir conductes emocionals de risc, la següent proposta conté un apartat de regulació emocional i d'organització d'aula, així com una metodologia setmanal basada en assemblees per a tractar les emocions i les tècniques de regulació i expressió. Finalment, la proposta d'intervenció ha sigut adaptada entorn de la legislació actual.The current education needs a different approach, which focuses equally on the teaching of academic areas, as well as on emotional education, since current schools don´t offer the necessary attention to factors as important as frustration, problems in the emotional expression or the difficulty in regulating emotions by the students.
Therefore, this Final Degree Project is going to analyze of the concepts of frustration, emotional education and the main theories about emotional intelligence with the aim of knowing the value of self-concept and the motivation in learning. In addition, an analysis of the emotional development of the students will be carried out, as well as of the factors that cause frustration in learning, the main family profiles and their influence, the classroom climate and the characteristics of the teachers.
On the other hand, an annual intervention will be prepare that promotes a scheduled follow-up of the students through objectives and organizational techniques for the prevention of frustration, both academic and personal through an emotional agenda. At the same time and with the aim of distinguishing emotional risk behaviors, the following proposal contains a section on emotional regulation and classroom organization, as well as a weekly methodology based on assemblies to deal with emotions and regulation and expression techniques. Finally, the intervention proposal has been adapted around the current legislation.Educació

However, due to the increase in the use of screens by children, several negative
repercussions can be observed and must be addressed. The purpose of this paper is to
expose one of the most current problems in children at the Early Childhood Education
stage: the irresponsible and inappropriate use of screens. In order to do so, a theoretical
framework has been drawn up, based on the search of specialised bibliographical
references, in which an overview is made of how technology has been infiltrating society
and, consequently, our educational system. At the same time, key ideas on this topic are
developed, such as recommendations for its use by various institutions, negative
repercussions, the process of digital disaffection and the benefits and appropriate use of
devices in educational contexts. Later on, a practical project has been developed based on
the analysis of the responses of certain families to a survey related to the subject and a
school for families that has as its central element an informative guide on the correct and
responsible use of new technologies in children under six years of age. In conclusion, the
aim of this work is to address one of the needs that can be observed most commonly in a
classroom at this stage of education.Educació
Dynamic mathematical model as a tool for detecting and preventing school violence: a case report
Get PDFCurrently, coexistence is an essential factor that influences educational quality.
Issues relating to school violence affect a large number of students, affecting their
personal, academic, and professional futures. For this reason, this study aimed to
present a different study tool that would allow the optimization of the factors that
influence classroom climate, establish mechanisms to detect and predict how the
modification of these factors can positively or negatively affect it, and determine
the most appropriate intervention before it occurs. Dynamic mathematical models
are complex tools that allow us to study a given problem or reality in real-time and
develop predictive instruments through the analysis of mathematical relationships,
allowing us to adapt the answers in a customized manner. In this study, an example
is provided in measuring classroom climate throughout an academic course in a
simulated situation. It consists of a dynamic mathematical model developed with
Stella 10.0 software using only some of the variables that affect classroom climate,
which are distributed in two sections—a psychological one that includes Rabies
Level and Isolation Level due to loss of self-esteem and a physical one that includes
the number of aggressive students and the total number of physically assaulted
students. Since the classroom climate is very complex, other variables or a greater
number of them could have been used in this hypothetical case; however, the
example explains how this kind of model works and shows the great utility that
it can have in this type of study. Regarding the most significant benefits that this
tool can offer, some stand out. On the one hand, we can adapt the instrument
to the specific characteristics of a class group, introducing or eliminating the
variables depending on their relevance to the problem at hand. On the other hand,
this versatile tool not only adapts to the reality of the classroom but also to the
specific moment in which the students are. The greatest limitation of a Dynamic
Mathematical Model as a tool is the large quantity of information required to adjust
the model to reality; the more information we have, the more adjusted the model
can be. Furthermore, gathering the type of information needed to develop the
model is complicated.Educació
