Assessment of the influence of overweight and obesity on the development of prehypertension and hypertension in children aged 6-15
Authors: Jandrić-Kočić Marijana
Published: January 2022

Introduction/Aim: 41 million children under the age of 5 and 340 million children and adolescents aged 5 to 19 are overweight or obese. Obesity in children and adolescents is the most important predictor of high blood pressure. The aim of the study was to examine the incidence of overweight and obesity in primary school children aged 6 to 15 years, as well as to examine the incidence of prehypertension and hypertension in children who were overweight and obese. Method: The study included 85 of 86 children from the Primary School "Krupa na Uni". Data were collected with the help of a questionnaire, while body weight and blood pressure were measured. The chi-square test and t-test were used for the statistical analysis of data Results: The cross-sectional study included 85 children, 45 (52.9%) boys and 40 (47.1%) girls with an average age of 10.87 ± 2.70 years. Normal weight was found in 54 (63.5%) subjects, underweight in 12 (14.1%), overweight in 5 (5.9%), and obesity in 14 (16.5%). 76 (89.4%) subjects had normal blood pressure values, 5 (5.9%) prehypertensive state, and 4 (4.7%) arterial hypertension. There was no significant difference between younger and older children regarding their nutritional status (p=0.477) and blood pressure levels (p=0.453). Children who were overweight and obese had prehypertension and hypertension significantly more often (p˂0.001). Conclusion: Every fifth child was overweight or obese, while prehypertension or hypertension were found in every tenth child. The timely change of diet and physical activity could contribute to the regulation of body weight and the regulation of blood pressure, as well.
The science behind medical marijuana and research challenges
Authors: Knežević Nebojša , Pirvulescu Iulia
Published: January 2022

Endocannabinoids are lipid-based retrograde neurotransmitters that bind to cannabinoid receptors, two of which are currently described: CB1 and CB2. The two main active components of cannabis are tetrahydrocannabinol (THC) and cannabidiol (CBD), have differing binding affinities to the receptors, allowing them to mediate different systemic effects as well as modulate each other's effects. Due to these varied properties, the therapeutic effect of marijuana is directly correlated with the THC:CBD ratio in a particular formulation. Current FDA-approved synthetic and cannabis-derived products are indicated for the treatment of nausea induced by chemotherapy, seizure disorders, and anorexia in AIDS patients. Regarding the treatment of chronic neuropathic pain and cancer pain, research has shown a low-to moderate quality evidence for use of cannabinoids, but greatly promising in providing alternatives to opioids. Challenges in medical research on cannabis remain, particularly in terms of inconsistent chemical composition and sourcing, small sample sizes, poor controls, and short duration of trials. Major medical institutions call for more thorough research and further investigation of marijuana safety and efficacy.
Segregación social y equidad educativa en Chile y Argentina
Authors: Miguez Daniel Pedro , Beech Jason , Nigro Malena
Published: January 2022

El propósito de este artículo consiste en comparar los niveles de segregación social en los sistemas educativos de Chile y Argentina y su relación con el acceso equitativo al saber escolarizado en ambos países. Complementariamente nos proponemos explorar si las políticas de financiamiento de la educación orientadas por la lógica de libre mercado aplicadas en Chile generaron niveles excepcionales de segregación social en comparación con la Argentina. Donde las políticas de financiación educativa preservaron la centralidad de la educación pública y gratuita. Método: El análisis se realiza mediante el uso de brechas percentílicas en base a los datos PISA 2012. Se estiman los niveles de segregación según el nivel educativo de los padres, el porcentaje de estudiantes en las escuelas con mayores niveles de segregación y la asociación entre los niveles de segregación y el desempeño de los estudiantes en las Pruebas. Resultado: el estudio muestra patrones de segregación complejos. En Chile los grados de segregación son mayores, pero la proporción de población en escuelas con alta segregación es baja y hay mayor equidad en la distribución del conocimiento. En Argentina hay menores grados de segregación, pero la proporción de la población en escuelas con alta segregación es mayor y hay mayor heterogeneidad en el acceso al conocimiento. Discusión: Los patrones de segregación encontrados muestran matices que no confirman plenamente la hipótesis de partida. En vez, sugieren que  la segregación social se daría con o sin mecanismos de mercado, que estos últimos no necesariamente introducen mayores niveles de inequidad y que las formas y niveles de desigualdad varían según los aspectos o dimensiones del sistema educativo que se consideren.

GÉNERO Y ANTOLOGÍAS: LA REVISIÓN DEL CANON EN LA ERA DE LA CIBERCULTURA Y EL PROYECTO CIEN DE CIEN (2015-2016)
Authors: FERNÁNDEZ MENÉNDEZ Raquel
Published: January 2022

En este artículo se estudia la importancia que Internet ha tenido en los últimos años en la recepción de las poetas españolas contemporáneas. Para ello, se recurre tanto a la teoría literaria feminista y al ciberfeminismo como a algunas de las contribuciones clave en el estudio de los procesos de canonicidad, específicamente, a la sociología de Pierre Bourdieu y a la teoría de los polisistemas de Itamar Even-Zohar. Desde este marco teórico, se analiza la antología virtual Cien de cien de Elena Medel, una selección que permite repensar las relaciones entre autoridad, cánones y cibercultura en el siglo XXI.
Abstract: This article aims to study the importance that the Internet has had in the reception of Spanish women poets in the last few years. For that purpose, feminist literary criticism and cyberfeminism will be used, as well as some of the key contributors to the study of canon, particularly Pierre Bourdieu’s sociology and Itamar Even-Zohar’s theory of polysystems. With this theoretical framework, attention will be paid to the digital anthology Cien de cien by Elena Medel, which enables us to rethink the relationship between authority, literary canons and cyberculture in the 21st Century.
Validation and measurement invariance of the Compound PsyCap Scale (CPC-12): a short universal measure of psychological capital
Authors: Platania Silvia , Paolillo Anna
Published: January 2022

The Compound PsyCap Scale (CPC-12) was developed by Lorenz et al. (2016) to broaden the application of psychological capital, since usually tied to workplace settings; however, no further verification of its suitability across different samples was performed. The present work investigated the psychometric properties of an Italian adaptation of the CPC-12 with the aim of verifying its applicability in samples where the item wording of the existing measures of PsyCap might not be suitable (e.g., students and unemployed people). Study 1 (n = 450) examined the factor structure of the scale. Study 2 (n = 255) advanced the previous CPC-12 validation by testing its measurement equivalence across gender through MCFA. Results confirmed a one higher-order factor structure with four first-order factors, the scale was found to be invariant across gender. The findings advanced the general claim of CPC-12 to be suitable for application in multiple contexts, including sport, education, vocational guidance, as well as typical and atypical work settings.

Lorenz y sus colegas desarrollaron la Escala Compound PsyCap (CPC-12) para ampliar este enfoque de dominio específico; sin embargo, no se realizó ninguna verificación adicional de su idoneidad en diferentes muestras / entornos. El presente trabajo investigó las propiedades psicométricas de una adaptación italiana del CPC-12 con el objetivo de verificar su aplicabilidad en muestras donde la redacción de los ítems de las medidas existentes de PsyCap podría no ser adecuada (por ejemplo, estudiantes y desempleados). El estudio 1 (n = 450) examinó la estructura factorial de la escala. El estudio 2 (n = 255) avanzó en la validación anterior de la CPC-12 al probar su equivalencia de medición entre sexos a través de MCFA. Los resultados confirmaron una estructura factorial de un orden superior con cuatro factores de primer orden; se encontró que la escala era invariante en todos los sexos. Los hallazgos avanzaron la afirmación general de la CPC-12 de ser adecuada para su aplicación en múltiples contextos, incluidos el deporte, la educación, la orientación profesional, así como los entornos laborales típicos y atípicos.

Published: January 2022

Background: The Childhood Executive Functioning Inventory (CHEXI) was designed to identify EF deficits in daily life contexts. The aim of the present study was to validate the Spanish version of the CHEXI in 4-5-year-old children. Method: Parents’ ratings of the CHEXI and laboratory tests of EF were investigated in two large samples of 445 children aged 4 years (196 girls, 249 boys) and 459 children aged 5 years (208 girls, 251 boys). CHEXI ratings were collected again after one-year. Results: The two-factor structure of the CHEXI (i.e., Working Memory and Inhibition) was replicated, showing high internal consistency and temporal stability. The 4-year-olds were reported to have higher EF deficits than 5-year-olds have. Boys were rated as having higher EF deficits than girls were. However, gender differences were not significant contrasting performance on EF tasks. Finally, associations between CHEXI ratings and EF tests were weak, suggesting that EF tests and EF ratings capture different aspects of EF. Conclusions: The Spanish CHEXI provides a suitable instrument to assess EF in 4-5-year-old children.

Contexto: El Childhood Executive Functioning Inventory (CHEXI) se diseñó para detectar déficit de Funciones Ejecutivas (FE) en contextos de la vida diaria. El propósito del presente estudio era validar la versión española del CHEXI para niños de 4 y 5 años. Método: Se obtuvieron las valoraciones de los padres y las puntuaciones en test de laboratorio en una muestra de 445 niños de 4 años (196 niñas, 249niños) y otra de 459 niños de 5 años (208 niñas, 251 niños). Un año más tarde se volvieron a recoger las valoraciones de los padres en CHEXI. Resultados: Se replicó la estructura de dos factores de CHEXI (Memoria de Trabajo e Inhibición), obteniendo una alta consistencia interna y estabilidad temporal. Los niños de 4 años eran valorados con mayor déficit en FE que los niños de 5 años. Los niños alcanzaban puntuaciones más elevadas de déficit de FE. Sin embargo, no aparecieron diferencias significativas de género en las pruebas conductuales. Finalmente, se encontró una baja asociación entre las valoraciones de CHEXI y las puntuaciones de las pruebas conductuales. Este resultado sugiere que los inventarios y las medidas conductuales evalúan diferentes aspectos de las FE. Conclusiones: La versión española de CHEXI ofrece un instrumento válido para evaluar las FE en niños de 4 y 5 años.
Resilience and associated factors in women survivors of Intimate Partner Violence: a systematic review
Authors: Fernández Álvarez Natalia , Fontanil Gómez Yolanda , Alcedo Rodríguez Ángeles
Published: January 2022

Most research on Intimate Partner Violence against women (IPV) has tended to present women as passive victims, but in recent years, there has been an increase in studies adopting a strengths-based approach. The aim of the present study is to review the empirical literature about resilience in women survivors of IPV to (a) analyze the consensus on the definition and assessment of resilience; (b) study the correlates of resilience; and (c) reflect on the applicability of such knowledge in policies and professional practice. Following PRISMA guidelines, a systematic search was carried out in the Scopus, WoS and PsycINFO databases. The search yielded 42 articles published in English or Spanish over an unlimited timeframe. Results showed that process-oriented, trait-oriented, and outcomes-oriented definitions of resilience were all adopted in the research and that assessment methods also differed across studies. Individual, relational, and contextual factors were found as resilience correlates.There is a need for a theoretical consensus and for research on the mechanisms through which vulnerability or protective factors exert their influence on groups with specific risk conditions. Finally, governments and institutions should take actions to support women and children and to prevent future IPV.

Gran parte de los estudios sobre Violencia de Género en la Pareja (VGP) presentan a las mujeres como víctimas pasivas, pero en los últimos años el número de investigaciones centradas en fortalezas está aumentando. El objetivo del presente estudio es revisar la literatura empírica sobre resiliencia en mujeres supervivientes de VGP para: (a) analizar el consenso en la definición y evaluación de resiliencia; (b) estudiar los correlatos del constructo; y (c) reflexionar sobre la aplicabilidad de este conocimiento en las políticas y la práctica profesional. Siguiendo las guías PRISMA, se realizó una revisión sistemática en las bases de datos Scopus, WoS y PsycINFO, encontrando 42 artículos publicados en inglés o español sin restricción temporal. Los resultados muestran que los estudios adoptan definiciones de resiliencia tanto orientadas al proceso como al rasgo y a los resultados, y que el método de evaluación difiere entre investigaciones. Entre los correlatos de resiliencia se encontraron factores individuales, relacionales y contextuales. Se necesita un consenso teórico y profundizar en los mecanismos por los cuales los factores de vulnerabilidad o protección afectan a grupos con riesgos específicos. Por último, los gobiernos e instituciones deberían  emprender acciones de prevención y de apoyo a las mujeres e hijos/as.

Authors: Martínez-Borba Verónica , Osma Jorge , Crespo-Delgado Elena , Andreu-Pejo Laura , Monferrer-Serrano Alba
Published: January 2022

Emotional Disorders (EDs) are common in women who undergo fertility treatments. The Unified Protocol (UP) is a transdiagnostic intervention that has demonstrated efficacy in preventing EDs under different health conditions. The aim of this pilot study is to: 1) improve emotional dysregulation for the prevention of anxiety and depressive symptoms in women undergoing intrauterine inseminations (IUI); 2) assess their acceptability (e.g., satisfaction and adherence rates). Method: Five women undergoing IUI, with no clinical diagnoses, responded to measures of mood (anxiety and depression), affect, quality of life and emotional dysregulation in the pre- and post-assessments, and at the 1-, 3- and 6-month follow-ups. The UP was adapted to be applied during six face-to-face group sessions lasting 2 h. The COVID-19 pandemic situation implied changing to an online format to end the program. Results: The results showed that women did not develop EDs, and no statistically significant pre-post and pre-follow-up differences were found for anxiety, depression, quality of life and emotional dysregulation (all p > .050). A tendency towards improvement in the post-assessment evaluation was noted. Satisfaction with the format and UP program was high. Conclusions: It would seem that programs focusing on therapeutic common factors like the UP could have an emotional preventive effect during IUI.

Los trastornos emocionales (TE) son frecuentes durante los tratamientos de fertilidad. El Protocolo Unificado (PU) es una intervención transdiagnóstica que ha demostrado su eficacia en la prevención de TE en condiciones médicas. El objetivo de este estudio piloto es: 1) mejorar la disregulación emocional para prevenir síntomas ansiosos y depresivos en mujeres en tratamiento de inseminación artificial (IA); 2) evaluar la aceptabilidad (satisfacción y adherencia). Método: 5 mujeres en tratamiento de IA, sin diagnóstico clínico, respondieron a medidas de estado de ánimo (ansiedad y depresión), afecto, calidad de vida y regulación emocional en el pre- y post-evaluación, y en los seguimientos a los 1, 3 y 6 meses. La adaptación preventiva del PU se basó en la aplicación de 6 sesiones presenciales grupales de 2 horas de duración. La situación generada por la COVID-19 provocó el cambio al formato online para finalizar el programa. Resultados: las mujeres no desarrollaron TE, no se encontraron diferencias pre-post y pre-seguimientos estadísticamente significativas en ansiedad, depresión, calidad de vida y disregulación emocional (p > .050). Se observa una tendencia a la mejoría en la evaluación post-programa. Conclusiones: Parece que programas como el PU, centrado en factores terapéuticos compartidos, ha tenido un efecto emocional preventivo durante IA.

Published: January 2022

The aim of the present study is exploring the mediation role of anxiety sensitivity on the relationships between intolerance of uncertainty and fear of COVID-19. The study was conducted with the relational screening method. The research data were collected online from 302 individuals (Male n = 76, Female n = 226) with Fear of COVID-19 Scale, Anxiety Sensitivity Index-3, Intolerance of Uncertainty Scale. The result of both mediation analysis and bootstrapping analysis (with 5000 bootstrap resamples) showed that the relationship between intolerance of uncertainty and fear of COVID-19 was mediated by anxiety sensitivity. Anxiety sensitivity decreased the effect of intolerance of uncertainty on fear of COVID-19. Moreover, comparing intolerance of uncertainty and anxiety sensitivity in terms of their predictive levels of the fear of COVID-19, it was concluded that anxiety sensitivity predicted the fear of COVID-19 more, and that anxiety sensitivity included the variance of intolerance to uncertainty associated with the fear of COVID-19.

El objetivo del presente estudio es explorar el papel mediador de la sensibilidad a la ansiedad en las relaciones entre la intolerancia a la incertidumbre y el miedo al COVID-19. El estudio se realizó con el método de cribado relacional. Los datos de la investigación se recopilaron en línea de 302 personas (hombres n = 76, mujeres n = 226) con la escala de miedo a COVID-19, índice de sensibilidad a la ansiedad-3, escala de intolerancia a la incertidumbre. El resultado tanto del análisis de mediación como del análisis bootstrapping (con un remuestreo de 5000 bootstrap) mostró que la relación entre la intolerancia a la incertidumbre y el miedo al COVID-19 estaba mediada por la sensibilidad a la ansiedad. La sensibilidad a la ansiedad disminuyó el efecto de la intolerancia a la incertidumbre sobre el miedo al COVID-19. Además, al comparar la intolerancia a la incertidumbre y la sensibilidad a la ansiedad en términos de sus niveles predictivos del miedo al COVID-19, se concluyó que la sensibilidad a la ansiedad predijo más el miedo al COVID-19 y que la sensibilidad a la ansiedad incluyó la varianza de la intolerancia a la incertidumbre asociada. con el miedo al COVID-19.
Aoristic Drift and Narrative Perfect in Early Modern English
Authors: Bondar Vladimir
Published: January 2022

In the current study, data from A Corpus of English Dialogues (1560-1760) are used to consider contexts with the have-perfect and temporal adverbs of the definite past time such as yesterday, last night, ago. Data analysis is conducted within the framework of a usage-based approach, which gives evidence to the hypothesis that in Early Modern English the have-perfect in spoken register was gradually developing perfective semantics and that it followed the stages of generalization of meaning depending on the degree of event remoteness. Investigation of the instances where the have-perfect is used in narrative passages shows that the have-perfect in such contexts does not lose its pragmatic component of current relevance but is employed to highlight a crucial event out of a chain of past events. The paper proposes the hypothesis that the main mechanism preventing the have-perfect from further aoristicization is the operation of syntactic analogy within the syntactic paradigm of the present perfect, which had already fully developed by the time of Early Modern English.
Myth, Form and Intertextuality in Edwin Muir
Authors: Insausti Gabriel
Published: January 2022

Edwin Muir has often embarrassed critics as a rara avis. He was overlooked by anthologists before 1950 and, although subsequent anthologies never failed to include him, he was still hard to place for many readers. Labelled as a “traditionalist” or a “craftsman”, his later work proves however that Muir was much more. Understanding his use of myth, form and intertextuality enables us to rethink the significance of his work in the twentieth-century context.

Purpose: The paper is devoted to the actual problem of the existing differences in women’s and men’s entrepreneurship. The aim of the research is to assess the prevailing levels of women’s and men’s participation in entrepreneurial activity in modern national economies. Methodology: The study dealt with the problem of determining indicator values characterizing the early stage of entrepreneurship; mature (sustainable) entrepreneurship, as well as quitting business activities. The results of the surveys conducted in 59 countries throughout the Global Entrepreneurship Monitor Project were used as initial information. Findings: In the course of the research, nine indicators characterizing such stages as start-up and sustainable entrepreneurship along with the cessation of this activity were examined. The study developed the functions that show the distribution of the indicators in 59 countries describing women’s and men’s proportions at three main stages of entrepreneurship. Research limitations: The study had limitations on empirical data due to the fact that only 59 countries were considered. Originality: The attained results have indicated that there is a gender gap among the indicators of entrepreneurship in most countries, which means that women participate in it to a smaller extent than men. The methodological approach to assessing gender differences in entrepreneurship presented in the article can be applied in further research.
Leader or Leaderess? Consequences of Using Feminatives for the Perception of Leadership
Authors:   Wydział Zarządzania, Uniwersytet Warszawski, Kuźmińska Anna O.
Published: January 2022

According to the Implicit Leadership Theory, leadership roles are assigned in the process of social construction and depend upon the level of congruence with the cognitive representation of a leader. Previous studies show that this cognitive representation is much more likely to involve a leader being a male rather than a female. The article presents the results of an experiment aimed at tentatively verifying whether the use of the feminine forms could increase the cognitive availability of the representation of a woman as a leader. In the experiment, 135 teams (N = 307 respondents) were randomly assigned to one of two experimental conditions: 1) generic instruction (without the use of feminatives, “Please, draw a leader”), 2) inclusive instruction (using feminatives, “Please, draw a leader/leaderess”). The results showed a significant interaction between the experimental manipulation and the proportion of women in the team. The use of feminine forms increased the percentage of females drawn as leaders only in teams with a high female-to-male ratio.
Higher Education Efficiency and Quality

Published: January 2022

The efficiency and the quality of higher education institution was assessed with the use of process approach. The efficiency of the higher education institution was determined on the basis of a combination of typical financial measures, taking into account costs incurred in the process of didactics and research, and expenditures (measured by current liquidity, stock turnover, receivables and liabilities ratios) necessary for schools to maintain financial liquidity. As measures of quality, related to statutory tasks of the university, the factors determining graduates’ situation on the labour market as well as patents obtained as a result of research conducted by university were adopted. Applying measures of quality enabled the researcher to obtain a more comprehensive dimension of the universities’ efficiency, while proving the fact that financial measures alone may distort the actual picture of efficiency or even lead to erroneous conclusions. It can be hypothesized that in the case of a higher education institution that pursues its statutory goals of providing knowledge to the public by conducting didactics and research, the concept of efficiency should combine financial and qualitative dimensions. The results obtained in the study using the DEA method allow the researcher to determine the situation of the university for the period covered by the study.

International Experts’ Influence on Company Internationalization
Authors: Kravchenko Grygorii
Published: January 2022

Purpose: The article evaluates the associative relationship between international supervisory board experts and foreign ownership, along with the experts’ influence on the financial and operating performance of firms. The study was based on data collected for 257 companies listed on the Warsaw Stock Exchange in 2010–2015. Methodology: The dataset was built as a panel, and then generalized least squares regression models with a fixed or random effect were employed to test hypotheses. Findings: The findings of the study clearly show that the presence of investigated firms in foreign markets positively affects company performance. Moreover, models with dependent variables ROA and ROS show that supervisory board members with foreign experience positively affect profitability indicators of firms that do not operate on foreign markets. The data analyses reveal that international experts are more effective advisors for companies that conduct no business activities on foreign markets. Furthermore, the results show a positive moderate association between the share of international experts in supervisory boards and the share of foreign ownership in the company. Originality: The article contributes to the understanding of determinants and consequences of the presence of international experts in supervisory boards and company internationalization.
Value Co-Creation in Engineering Service Innovation: Resources and Capabilities Perspectives
Authors: Gegužytė Gintarė , Bagdonienė Liudmila
Published: January 2022

Purpose: This research focuses on firm resources and capabilities used for value co-creation in service innovation. Specifically, I investigated how service innovation is created in an in-ternational engineering company. The aim of this article is to reveal what resources and capa-bilities are employed by a service provider for value co-creation in the innovation project of engineering service and how they vary in particular stages of this project. Methodology: The research is based on qualitative methodology by a multi-case study strate-gy. Focus group discussion with senior managers and semi-structured interviews with project managers of the studied international engineering company were used as concrete data gather-ing methods. Data analysis was conducted using the content analysis method. Findings: The research revealed eight value co-creation activities accomplished by the engi-neering company and client during the engineering service innovation project. The activities are as follows: co-identification of the client’s problem, co-evaluation of ideas, co-defining of client’s requirements, co-analysis of environment, co-design, co-testing, and co-adoption, co-production, and co-activities after the launch. These activities are diffused in different project stages and demand a range of resources: expert knowledge, diagnostic, communication skills, trust, experience, technological equipment, human resources. Moreover, they require diverse capabilities: relational, innovative, analytical, negotiation, knowledge absorptive, planning, organizational flexibility, and cross-cultural. The intensity and variety of using the mentioned resources and capabilities differ relying on the value co-creation activity. Expert knowledge, communication skills as resources, and relational and innovative capabilities were empha-sized by the researchers most often. We hope these findings will represent a step toward a more coherent resource-based view (RBV) and service innovation theories. Implications: The study involved only one Lithuanian engineering company, so the research context may influence the findings. Another limitation is related to the small number of cases and research participants. Originality: Unlike previous studies that revealed the importance of single resources and ca-pabilities for service innovation, this study determined the range of resources and capabilities employed in different activities of engineering service innovation project stages, especially in the value co-creation activities performed by the engineering company and clients. Moreover, research also identified how resources and capabilities vary at different stages of these pro-jects.
Carlos Giménez, España, Una, Grande y Libre (1976-1977), and Comics of the Transition
Authors: Cate-Arries Francie
Published: January 2022

I reexamine the Spanish Transition in terms of the interventions that cartoonists in the 1970s used to lay bare the machinations of the old regime still in power. Specifically, I analyze Carlos Giménez’s España, Una, Grande y Libre series, an exemplary counter-narrative against the dominant discourse produced by post-Franco government officials and economic power brokers. This collection—which denounces state-sanctioned violence and champions popular mobilizations in the name of a more just society—is also a pioneering work that makes visible the victims of the long-silenced crimes of Francoism.

Laura Martínez Martín, la autora de esta brillante investigación, nos adentra en el apasionante mundo de la correspondencia privada y la emigración, dos realidades que mantuvieron un estrecho vínculo, hasta el punto de que no podemos entender la una sin la otra. Porque, en el pasado, la carta fue la principal y casi única vía de comunicación entre los emigrados y sus familias, la voz que en forma escrita minimizó el dolor por la ausencia de aquellos hombres y mujeres que tuvieron el arrojo o la inconsciencia de dejarlo todo para buscar oportunidades que en su entorno se les negaban.

Motor planning plays a critical role in producing fast and accurate movement. Yet, the neural processes that occur in human primary motor and somatosensory cortex during planning, and how they relate to those during movement execution, remain poorly understood. Here, we used 7T functional magnetic resonance imaging and a delayed movement paradigm to study single finger movement planning and execution. The inclusion of no-go trials and variable delays allowed us to separate what are typically overlapping planning and execution brain responses. Although our univariate results show widespread deactivation during finger planning, multivariate pattern analysis revealed finger-specific activity patterns in contralateral primary somatosensory cortex (S1), which predicted the planned finger action. Surprisingly, these activity patterns were as informative as those found in contralateral primary motor cortex (M1). Control analyses ruled out the possibility that the detected information was an artifact of subthreshold movements during the preparatory delay. Furthermore, we observed that finger-specific activity patterns during planning were highly correlated to those during execution. These findings reveal that motor planning activates the specific S1 and M1 circuits that are engaged during the execution of a finger press, while activity in both regions is overall suppressed. We propose that preparatory states in S1 may improve movement control through changes in sensory processing or via direct influence of spinal motor neurons.

Agouti-related peptide (AgRP) neurons increase motivation for food, however, whether metabolic sensing of homeostatic state in AgRP neurons potentiates motivation by interacting with dopamine reward systems is unexplored. As a model of impaired metabolic-sensing, we used the AgRP-specific deletion of carnitine acetyltransferase (Crat) in mice. We hypothesised that metabolic sensing in AgRP neurons is required to increase motivation for food reward by modulating accumbal or striatal dopamine release. Studies confirmed that Crat deletion in AgRP neurons (KO) impaired ex vivo glucose-sensing, as well as in vivo responses to peripheral glucose injection or repeated palatable food presentation and consumption. Impaired metabolic-sensing in AgRP neurons reduced acute dopamine release (seconds) to palatable food consumption and during operant responding, as assessed by GRAB-DA photometry in the nucleus accumbens, but not the dorsal striatum. Impaired metabolic-sensing in AgRP neurons suppressed radiolabelled 18F-fDOPA accumulation after ~30 min in the dorsal striatum but not the nucleus accumbens. Impaired metabolic sensing in AgRP neurons suppressed motivated operant responding for sucrose rewards during fasting. Thus, metabolic-sensing in AgRP neurons is required for the appropriate temporal integration and transmission of homeostatic hunger-sensing to dopamine signalling in the striatum.

In the past decade, several studies have estimated the human per-generation germline mutation rate using large pedigrees. More recently, estimates for various nonhuman species have been published. However, methodological differences among studies in detecting germline mutations and estimating mutation rates make direct comparisons difficult. Here, we describe the many different steps involved in estimating pedigree-based mutation rates, including sampling, sequencing, mapping, variant calling, filtering, and appropriately accounting for false-positive and false-negative rates. For each step, we review the different methods and parameter choices that have been used in the recent literature. Additionally, we present the results from a ‘Mutationathon,’ a competition organized among five research labs to compare germline mutation rate estimates for a single pedigree of rhesus macaques. We report almost a twofold variation in the final estimated rate among groups using different post-alignment processing, calling, and filtering criteria, and provide details into the sources of variation across studies. Though the difference among estimates is not statistically significant, this discrepancy emphasizes the need for standardized methods in mutation rate estimations and the difficulty in comparing rates from different studies. Finally, this work aims to provide guidelines for computational and statistical benchmarks for future studies interested in identifying germline mutations from pedigrees.

En este estudio se investigan las fuentes periodísticas utilizadas por la prensa mexicana en noticias sobre el feminicidio. El objetivo es analizar las dinámicas de la selección de esas fuentes con relación al género y su oficialidad. La investigación de corte cuantitativo estudia el contenido sobre el feminicidio y la violencia de género en cuatro periódicos mexicanos de tirada nacional: La Jornada, Reforma, El Universal y Milenio durante 2017. De 1324 textos, se analizaron 2091 fuentes. Estas se clasificaron con un modelo preestablecido: fuentes oficiales que aceptan la versión oficial respecto de la información sobre hechos de feminicidio, oficiales que rechazan la versión oficial, protagonistas de los hechos, víctimas de las situaciones y especialistas, expertas o con voluntad de expresarse. El resultado mostró que las fuentes femeninas cuestionan la versión oficial, mientras que las masculinas la apoyan y la sostienen. Asimismo, las fuentes femeninas tuvieron mayor presencia como expertas. Las fuentes femeninas construyen el discurso crítico sobre el feminicidio, mientras que las masculinas lo sostienen con versiones oficiales. La investigación constata un elevado nivel de discriminación hacia las mujeres como fuentes de información oficial en el tema del feminicidio en México. De hecho, se puede afirmar que el género es una categoría que los medios de comunicación usan para discriminar las fuentes válidas en la construcción del hecho noticioso.

El marketing de influencia es un fenómeno en auge. Cada vez más organizaciones recurren a influencers para comunicar su mensaje a través de las redes sociales, sobre todo en Instagram y YouTube. En este trabajo analizamos el uso que hacen de los influencers las diez empresas turísticas españolas con mayor inversión publicitaria durante 2019 en esas dos redes sociales. Se emplea una metodología de modelo mixto para analizar la utilización de este tipo de figuras en la comunicación de las entidades, detectar los tipos de perfiles profesionales a los que se recurre y determinar si su empleo aumenta el valor de las cuentas organizacionales. Los resultados evidencian preferencia por Instagram frente a YouTube, un aumento del Earned Media Value, y que 60% de las empresas analizadas recurren a influencers en su comunicación habitual, aunque apuestan por especialistas y no necesariamente a perfiles con un número mayor de seguidores.

Esta investigación explora la evolución de la rutina periodística de la pauta en los medios digitales en Chile en los últimos años. Se examina específicamente cómo se elabora la pauta, el rol del editor y la influencia de la audiencia para seleccionar y jerarquizar los contenidos. Se contempló una muestra de los diez medios digitales más leídos en Chile en 2020 y se aplicaron entrevistas en profundidad a sus editores o directores. Los principales resultados apuntan a una diferenciación entre medios matriciales y medios nativos digitales. Mientras que los medios matriciales tienen una injerencia menos directa del editor sobre los periodistas y las respuestas del público afectan fuertemente la selección de contenidos, los medios nativos digitales mantienen un estilo más tradicional de elaboración de sus pautas y noticias. En estos últimos, los editores tienen mayor injerencia sobre los periodistas, las reuniones de pauta suelen hacerse una vez al día y los contenidos están poco condicionados por las métricas y las redes sociales. Aunque el estudio es una fotografía de algunos medios digitales chilenos, permite concluir que la evolución del periodismo en línea en Chile ha sido rápida, se le da mayor importancia a la pauta, se ha perfilado más la figura del editor, y la influencia de la audiencia en los contenidos es cada vez más importante respecto de unos años atrás.
Probability Density Functions for Prediction Using Normal and Exponential Distribution
Authors: Takezawa Kunio
Published: January 2022

When data are found to be realizations of a specific distribution, constructing the probability density function based on this distribution may not lead to the best prediction result. In this study, numerical simulations are conducted using data that follow a normal distribution, and we examine whether probability density functions that have shapes different from that of the normal distribution can yield larger log-likelihoods than the normal distribution in the light of future data. The results indicate that fitting realizations of the normal distribution to a different probability density function produces better results from the perspective of predictive ability. Similarly, a set of simulations using the exponential distribution shows that better predictions are obtained when the corresponding realizations are fitted to a probability density function that is slightly different from the exponential distribution. These observations demonstrate that when the form of the probability density function that generates the data is known, the use of another form of the probability density function may achieve more desirable results from the standpoint of prediction.
