Pre-service teachers’ perceptions of data protection in primary education
The protection of personal data and privacy are important issues closely related to use of social
media, information and communication technologies, and the Internet in the area of education.
The treatment of academic information and use of tools and programs for instruction,
communication, and learning have revealed the handling of a significant volume of personal
data from different sources. It is essential to protect this information from possible privacy
violations. This descriptive study, which is of transversal nonexperimental design, focuses on
how 384 pre-service teachers’ enrolled in educational technology courses in their education
programs view the protection of personal data. The goals are to describe and analyze how these
teachers perceive the risks associated with protection of data on the Internet and what they
know about protection of data in primary education. We administered a questionnaire within
the framework of an educational activity that focused on digital competence in data protection
in education. The results show a high perception of risk in topics such as accepting cookies when
surfing the Internet or transferring banking information. The knowledge the students claim to
have shown a lack of information on the protection of minors’ data in issues related to the
development and schooling of primary school students, as well as their health, background, and
family environment. Curricular treatment of these areas that includes content, practices on
regulations, and adopts a situated, critical, and responsible approach in pre-service teacher
education is recommended.Spanish Ministry of Education & Vocational Training (Reference: FPU17/05164
Indicators to assess preservice teachers’ digital competence in security: A systematic review
Funding for open access charge: Universidad de Granada/CBUA. Spanish Ministry of Education, Culture and Sport.The goal of this review is to analyse the state of inquiry in the field of digital competence
in security in initial teacher education, via indicators to assess preservice
teachers’ digital competence in security, in order to help find opportunities to
improve their competence level. Following the parameters defined in the PRISMA
declaration, the review uses a bibliographic research methodology to explore the
WoS, Scopus and ERIC databases. After a search identifying a sample of 31 scholarly
articles published between 2010 and 2021, we analyse the information obtained
using descriptive statistics and content analysis. The results show a predominance of
empirical research in the European context. These studies are quantitative and tend
to use questionnaires. Our conclusion proposes the need to train preservice teachers
in data protection and privacy, searching for and using Internet images with authorship
screening, use of open software programs, and respect for online communication
norms, as well as ethical and responsible technology use. All of these issues are
implicitly and transversally linked to the area of digital competence in security.Spanish Governmen
Internet Risk Perception: Development and Validation of a Scale for Adults
Despite the importance of Internet risk perception, no instrument currently exists that
measures this awareness in the Spanish population. The goal of this study was to provide information
on studies of the validity and reliability of the Internet Risk Perception (IRP) Scale for adult Spanish
citizens. We began with a literature review and validation using a mixed panel with 20 participants.
We analyzed the degree to which the subjects agreed or disagreed with the criteria evaluated,
including contributions for improving the instrument, and performed a pilot test with 517 adults
aged 18 to 77. Construct reliability and validity were analyzed using various statistical analyses. The
results from the confirmatory factor analysis showed a sufficient accuracy of the data with parameters
that indicated an excellent fit for all items. The Spanish version of the scale for adults is a reliable and
valid instrument for use in studies that investigate Internet risk perception in people over 18 years
of age.Operational Program FEDER 2014-2020/Andalusian Regional Government/Regional Ministry of Economic Transformation, Knowledge, and Universities of Andalusia/Project B-SEJ-102-UGR18Spanish Government FPU17/0516
An Educational Framework in Digital Rights and Responsibilities for Young Entrepreneurs
A strong link currently exists between entrepreneurship and use of technology and the Internet, primarily because young
people increasingly use digital and online strategies to start and develop entrepreneurial initiatives. The goal of this document
analysis is to propose a reference framework for digital rights in youth entrepreneurship based on selection and analysis of
20 documents with legislation, regulations, and reports that focus on guaranteeing safe, responsible digital environments. The
study resulted in a framework for connecting digital rights and responsibilities with young entrepreneurs, based on three
main points: rights to equality and participation; rights to freedom; and rights to development, creation, and sustainability. In
addition to including concepts, practices, and applications in young people’s initiatives, the framework is useful for educating
young entrepreneurs, guiding future research, and helping public administrations to promote the guarantee of digital rights
and responsibilities for all.Funding for Open Access Charge:

Digital Rights and Responsibility in Education: A Scoping Review
Studies on digital rights in education have both gained attention and provided a framework for research, policy and practice in educational research within the field of educational technology. The potential benefits we appreciate in Internet use are inseparable from the maximum risks involved. Faced with this responsibility, individuals demand that their rights and freedoms be guaranteed in the digital environment according to their various roles as students, teachers, families or staff. This scoping review selects and analyses 54 theoretical and empirical studies from the last decade (2013-2023), identifying the main topics investigated as privacy protection in online environments, right to digital security or cybersecurity, and right to digital education. The review underscores the need to guide efforts towards digital education for citizens because the legal regulation of rights and responsibilities is necessary but insufficient. The paper also makes arguments about acceptance, limitations and implications for teacher training.European Regional Development Fund’s 2014-2020 Operational Program, the Andalusian Government, and Spain’s Department of Economic Transformation, Industry, Knowledge and Universities (Project A.SEJ.46.UGR 2020)
La evaluación en informes de prácticas del grado de Maestro en Educación Primaria
Los períodos de Prácticum son una oportunidad de aprendizaje y de adquisición de conocimientos estratégicos sobre la profesión de maestro. Son momento y espacio para comprender realidades, reflexionar, (re)construir conocimientos y asumir crítica y constructivamente las limitaciones y necesidades personales y profesionales. Los seminarios y la inmersión en las aulas dan forma a las prácticas externas académica y organizativamente. Los informes de prácticas (diarios y memorias) se utilizan para describir, reflexionar y sistematizar las conexiones entre la teoría y realidad del aula. Este artículo describe la práctica de la evaluación en la educación primaria a partir de un análisis de contenido de informes elaborados durante diferentes períodos de prácticas en un centro educativo español. Es un estudio de caso que proyecta realidades, problemas y cambios sobre este tema a partir de una experiencia que puede aportar elementos para la reflexión y el aprendizaje

Melatonin activates endoplasmic reticulum stress and apoptosis in rats with diethylnitrosamine-induced hepatocarcinogenesis
Abstract Hepatocellular carcinoma (HCC) is one of the most lethal human cancers worldwide because of its high incidence, its metastatic potential and the low efficacy of conventional treatment. Inactivation of apoptosis is implicated in tumour progression and chemotherapy resistance, and has been linked to the presence of endoplasmic reticulum stress. Melatonin, the main product of the pineal gland, exerts anti-proliferative, pro-apoptotic and antiangiogenic effects in HCC cells, but these effects still need to be confirmed in animal models. Male Wistar rats in treatment groups received diethylnitrosamine (DEN) 50 mg/kg intraperitoneally twice/once a week for 18 weeks. Melatonin was given in drinking water at 1 mg/ kg/d, beginning 5 or 12 weeks after the start of DEN administration. Melatonin improved survival rates and successfully attenuated liver injury, as shown by histopathology, decreased levels of serum transaminases and reduced expression of placental glutathione S-transferase. Furthermore, melatonin treatment resulted in a significant increase of caspase 3, 8 and 9 activities, polyadenosine diphosphate (ADP) ribose polymerase (PARP) cleavage, and Bcl-associated X protein (Bax)/Bcl-2 ratio. Cytochrome c, p53 and Fas-L protein concentration were also significantly enhanced by melatonin. Melatonin induced an increased expression of activating transcription factor 6 (ATF6), C/EBP-homologous protein (CHOP) and immunoglobulin heavy chain-binding protein (BiP), while cyclooxygenase (COX)-2 expression decreased. Data obtained suggest that induction of apoptosis and ER stress contribute to the beneficial effects of melatonin in rats with DEN-induced HCC

Evaluación del conocimiento sobre efecto del cigarrillo en internas fumadoras. Pereira 2004
El objetivo general de este estudio fue evaluar el nivel deConocimiento sobre los daños causados por el cigarrillo, en las internas que fuman en un Establecimiento Penitenciario y Carcelario de Mujeres de Pereira, durante el segundo semestre de 2004. Inicialmente se identificaron y cuantificaron las condenadas fumadoras, obteniendo como población estudio un total de 34 internas entre las 149 presentes en la institución. Luego se aplicó una encuesta semiestructurada, la cual permitió recolectar las variables: continuas (nombre, edad etc.) y discontinuas, divididas en variables dicotómicas (procedencia, ¿tiene hijos?) y discretas (escolaridad, cambios en el organismo desde que comenzó a fumar). La información recolectada se condensó en una base de datos en epiinfo, la cual se analizó en forma univariada; posteriormente se realizó análisis bivariado, entre las variables más representativas. Las principales limitaciones en el desarrollo del trabajo fueron la falta de cooperación de las internas, algunas de las cuales presentaron una actitud apática y desconfiada alterando los datos de la encuesta y ocasionando de esta manera sesgos de información, además del horario para la recolección de información, ya que se cruzaba con otras actividades realizadas por ellas o por los estudiantes. El 91% de las internas conoce que el hábito del cigarrillo trae efectos adversos para la salud; de ese 91%, 52% cree que causa cáncer de pulmón; el 15% que causa ‘enfermedad en los pulmones’. El análisis bivariado mostró que a mayor edad, mayor es el conocimiento acerca de los efectos que el cigarrillo ejerce sobre la salud y la relación con el número de cigarrillos consumidos diariamente. Las internas tienen algún conocimiento de los efectos adversos del cigarrillo, porque la mayoría aceptó la relación de éste con enfermedades; pero la concordancia es básicamente para problemas respiratorios, más no para alteraciones sistémicas; además creen que todas las enfermedades respiratorias son causadas por el cigarrillo. El principal problema es que aún con el conocimiento de las posibles consecuencias que se derivan del hábito del cigarrillo, no muestran interés por dejarlo. Se recomienda establecer programas permanentes para proporcionar métodos o alternativas que les faciliten superar este hábito, sin que esto les afecte su estado emocional.
