On bayesian inference for almost periodic in mean autoregressive models
Authors: Lenart Łukasz , Mazur Błażej
Published: April 2020

The goal of the paper is to discuss Bayesian estimation of a class of univariate time-series models being able to represent complicated patterns of “cyclical” fluctuations in mean function. We highlight problems that arise in Bayesian estimation of parametric time-series model using the Flexible Fourier Form of Gallant (1981). We demonstrate that the resulting posterior is likely to be highly multimodal, therefore standard Markov Chain Monte Carlo (MCMC in short) methods might fail to explore the whole posterior, especially when the modes are separated. We show that the multimodality is actually an issue using the exact solution (i.e. an analytical marginal posterior) in an approximate model. We address that problem using two essential steps. Firstly, we integrate the posterior with respect to amplitude parameters, which can be carried out analytically. Secondly, we propose a non-parametrically motivated proposal for the frequency parameters. This allows for construction of an improved MCMC sampler that effectively explores the space of all the model parameters, with the amplitudes sampled by the direct approach outside the MCMC chain. We illustrate the problem using simulations and demonstrate our solution using two real-data examples.
The Application of an Accelerated Failure Time Model to the Survival Analysis of Enterprises Founded in Lesser Poland Voivodship
Authors: Gurgul Henryk , Zając Paweł
Published: April 2020

The goal of this research was the survival analysis of enterprises founded in Lesser Poland Voivodship between years 2006–2014. The sample comprising 267 thousands firms was used to examine whether certain factors such as the size of the company, area of its activity and registration place had statisti-cally significant impact on their duration time. All of those proved to be substantial in the course of our study. In general companies belonging to the sector of finance and insurance survived the shortest, whereas the longest duration (even four times longer than in finance and insurance) was among com-panies from mining sector, public administration, national defense and social insurance. Moreover, the research has proved that while moving further from Cracow, the survival of companies was likely to shorten. The only exception was Tatra Country, where duration was relatively long despite the distance factor. Additionally companies in urban areas were active approximately 9% longer than firms founded in rural ones. To the best of our knowledge this is the first application of an AFT (accelerated failure time)model to survival analysis of companies based on the data from Central European country. In this case its application proves existence of the heterogeneity of the hazard function.

Aim. Analysis of the distribution of foot force on the ground in children before and after kinaesthetic stimulation. Materials and methods. Research was conducted from April 11 to May 22, 2019, in two groups of children aged 7-12. The experimental group (E) consisted of children attending dance classes, while the control group (C) comprised their peers undergoing mandatory physical educations classes. To obtain answers to the posed research questions, the tests were carried out using a sub-pararographic mat. The results were analysed using the Statistica program. The authors are aware that some of the results obtained are nonparametric data, therefore, the non-parametric Mann-Whitney U test and the Kolmogorov-Smirnov test were used. Considering further results analysed via the Student’s t-test, non-parametric data were analysed for this test. Results. There were statistically significant differences between the average results of the subjects at the level of p<0.05 occurring before the introduction of kinaesthetic stimulation. Distribution of forces on the metatarsal bones of the left foot (pd0.04), the tarsus bones of the left foot (pd0.0078), the toes of the right foot (pd0.0039) and the metatarsal bones of the right foot (pd0.03). However, after stimulation, a statistically significant difference at the level of pd0.0076 occurred in the distribution of forces on the bones of the toes of the right foot. Analysing the average results, statistically significant differences were observed for COP distance (pd0.0001) and the area of t he body’s barycentre ellipse (pd0.01999). Conclusions. Dance practiced in childhood significantly affects the postural stability of the body and the distribution of forces on the ground. It was also noticed that when performing fast movements, there were noticeable differences in the body posture of dancing and non-dancing children.
A filosofia da Medicina de Família e Comunidade segundo Ian McWhinney e Roger Neighbour
Authors: Ramirez Jaco Beatriz , Norman Armando Henrique
Published: April 2020

Introdução: O presente artigo revisita os pressupostos filosóficos da Medicina de Família e Comunidade (MFC) a partir dos escritos de Ian McWhinney e Roger Neighbour. Objetivo: Fortalecer a discussão sobre as bases teóricas da MFC na academia e nos programas de residência em MFC. Métodos: Trata-se de um ensaio reflexivo que compara e analisa dois dos principais livros da MFC: o clássico “Manual de Medicina de Família” de Ian McWhinney e “The inner physician: why and how to practise ‘Big Picture Medicine’” de Roger Neighbour. Resultados e Discussão: Ian McWhinney e Roger Neighbour utilizam a epistemologia de Thomas Kuhn para propor um paradigma diferente à medicina. Nesse processo, os autores desenvolveram propostas distintas, porém complementares, que optamos por categorizar em: (a) paradigma organísmico de McWhinney e quântico de Neighbour; (b) distinção entre a prática generalista e a do especialista focal; e (c) relação médico-paciente e consigo mesmo. Conclusão: Para navegar nas incertezas da prática generalista é necessário fomentar e refletir a respeito da essência do MFC, tanto nos cursos de graduação quanto nos programas de residência, para formar profissionais sensíveis à condição humana.
Innovation Activity: Localization, New Trends and Assessment Methods
Authors: Amrin Aslanbek , Nurlanova Nailya
Published: April 2020

The purpose of this article is to identify trends and spatial features of the formation of "growth points" in Kazakhstan, based on characteristics of localization and concentration of innovative activity. The main attention in the article is given to the assessment of the various levels of industrial development and innovative activity of Kazakhstan regions, taking into account territorial features and the main directions of industrial development. The article discusses the basic concepts that explain the patterns of regional growth, the localization of high-tech industries and innovative activity, as well as methods for assessing them. Index and coefficient methods, ranking methods, grouping and rating methods were used for the analysis. To assess the innovative activity of regions, a modified rating scale was used, and a modified Krugman concentration index was proposed and used to assess the concentration of innovative activity. We have used relative indicators calculated on the basis of national statistics on science and innovations in Kazakhstan to build the ratings. The assessment of parameters of localization of scientific potential and innovative activity in Kazakhstan regions is carried out. The regions were ranked and the aggregated rating score for the regions was calculated. A typology of the regions of Kazakhstan was developed according to the level of innovation activity, four types of zones of localization of innovation activity were identified: high level (A), medium level (B), low level (C), unsatisfactory level (D). To characterize the local concentration of production of innovative products in Kazakhstan, modified Krugman concentration indices are calculated. The established zones (centers) of localization of innovative activity were identified, and it was concluded that they do not yet have a large impact on industrial development of the country as a whole. In general, positive trends in the growth of indicators of innovative activity and technological progress are observed throughout the country. Nevertheless, the rate of change remains extremely low, which indicates the uneven development of innovations in regions, as well as their territorial and industrial isolation, which has a negative impact on the speed of development of the technological process in the country.
Perfect Order and Its Components: Application for Deliveries of Fast Moving Consumer Goods to Retail Stores
Authors: Patak Michal , Branska Lenka , Pecinova Zuzana
Published: April 2020

The perfect order concept is traditionally used to measure logistics performance, but the conventional assessment of the perfect order from the perspective of the “in-time, in-full and error-free” trinity is no longer viable today. This paper aims to make a modest contribution to creating a novel understanding of the perfect order concept. Based on the primary survey in 132 Czech retail stores, the authors identify the key components that constitute a perfect order fulfilment of fast moving consumer goods to retail stores, namely reliability, collaboration, extra adaptation, ordering, and promotion. Subsequently, it was discovered that there are the differences in the influence of the identified components depending on the retail store type. Retail stores in the sense of drugstores regard extra adaptation and promotion as being the more important components compared to retail stores specialising in food products. Independent retail stores regard collaboration and promotion as being much less important components compared to retail stores that form part of a retail chain. Ordering is a more important component for small retail stores compared to large retail stores. Retail stores located in a capital city and in towns representing the centres of individual regions regard collaboration and extra adaptation to be the more important components compared to retail stores located in small towns. Research results support perfection in measuring logistics performance and make it possible to improve retail store operation.

Authors: Kędzior Marcin , Cyganska Malgorzata , Syrrakos Dimitrios
Published: April 2020

The paper examines the determinants of voluntary International Financial Reporting Standards (IFRS) adoption in Poland. In doing so, it empirically confirms the impact of diverse CEO and supervisory board characteristics on voluntary IFRS adoption. The paper focuses on  446 publicly traded production companies from Poland. The analysis is based on logistic regression analysis. The empirical investigation  confirms the impact on voluntary IFRS adoption of such factors as company size, international investors, international supervisory board, number of supervisory board members, CEO nationality. The paper  contributes to the assessment of  voluntary IFRS adoption determinants, by presenting for the first time CEO and supervisory board characteristics and their impact on voluntary International Financial Reporting Standards (IFRS) adoption, and the determinants of IFRS adoption from Central and Eastern Europe. The paper enhances  existing knowledge of voluntary IFRS adoption by incorporating  new CEO and supervisory board characteristics, thus closing a gap in the relevant literature. The results of the paper are significant from the supervisor’s perspective, the quality of financial statements and the effectiveness of corporate governance systems.
Directional Movement Distribution in the Bitcoin Markets
Authors: Szetela Beata , Mentel Grzegorz , Mentel Urszula , Bilan Yuriy
Published: April 2020

The crypto exchanges operate primarily on the internet, where the speed of information spreading is significant. Therefore, it is expected that there should be no significant differences among the individual exchanges concerning the same asset being traded. Prices should quickly reach comparable values on all stock exchanges, and they should return to equilibrium in a relative time frame. Hence, the investors, while making decisions on the selection of a cryptocurrency market, should be guided primarily by the exchange security considerations, its flexibility, availability of a product offer, and costs of order processing. The work aims to check whether virtual currency exchanges differ from each other in the context of directional movement, both in an upward and downward trend. To achieve the objective of the paper, we used Directional Movement Index, supported by the Directional Indicators, to compare the distribution of the strength of the directional movement across three different cryptocurrency exchanges (Bitstamp, Coinbase, Kraken) within the up and the downward price movement phase. The comparison is made based on the results of the non-parametrical tests such as Wilcoxon test, Hodges Lehmann test, Ansari-Bradley test, and Conover test. The results show that theoretically, the choice of a cryptocurrency exchange in an upward trend will cause no significant difference for an investor and its strategy. However, the choice of a stock exchange in a downward trend may have a substantial impact on the rates of return.

A complete mitogenome fromOrconectes (Procericambarus)cf.ozarkae(Williams)
Authors: Cabe Paul R.
Published: April 2020

Mitochondrial DNA sequences have been used extensively for studies of phylogeny, biogeography, and systematics in a vast array of taxa. In crayfish, the most widely used mitochondrial sequences are from the genes 16S ribosomal RNA, 12S ribosomal RNA, and cytochrome oxidase I. Other regions might perform well for certain questions, and entire mtDNA genome sequences might be very useful for phylogenetic studies, but these uses are curtailed by lack of sequence information. The complete mitochondrial genome from an individual of Orconectes cf. ozarkae (Williams) was sequenced, assembled, and annotated. The circular genome was 15,815 base pairs in length, and included the complement of 37 genes expected for metazoans, two ribosomal RNA genes, thirteen protein coding genes, and 22 tRNA genes. The gene order is equivalent to other species of crayfish from the family Cambaridae.
Fundamentos teóricos y factores explicativos de la Violencia filio-parental. Un estudio de Alcance.
Authors: Arias Rivera Shirley Jeannet , Hidalgo García María Victoria
Published: April 2020

La violencia filio-parental es un fenómeno de marcada prevalencia con consecuencias negativas a nivel individual, familiar y social.  El objetivo de este estudio de alcance fue identificar los factores explicativos y la fundamentación teórica del fenómeno. Se revisaron estudios en inglés y español desde el año 2000, de las bases: Web of Science, Scopus, PsycINFO, Eric y Dialnet Plus, identificando 57 estudios relevantes. Se encontraron como factores explicativos recurrentes: la monoparentalidad, la cohesión, el estrés y disciplina familiar, el historial de violencia, problemas escolares, trastornos clínicos y la relación con iguales violentos. Se destaca la concurrencia con la violencia escolar, entre hermanos y en las relaciones de noviazgo. Los fundamentos teóricos utilizados se pueden clasificar en psicológicos, comunicacionales, criminológicos, sociológicos y modelos integrativos más amplios (Ecosistémicos, Fenomenológicos y Constructivistas). La revisión realizada no arrojó datos sobre patrones de interacción, estrategias de afrontamiento y percepciones sociales alrededor de la VFP que puedan influir en las familias implicadas en estas situaciones.

Child-to-parent violence is a phenomenon with a fairly high prevalence rate and negative consequences at an individual, family and social level.  The aim of this scoping review was to identify the theoretical frameworks and explanatory factors for this phenomenon. The review comprised studies written in English and Spanish since the year 2000, from the following databases: Web of Science, Scopus, PsycINFO, ERIC and Dialnet Plus. A total of 57 relevant studies were identified. The recurrent explanatory factors were: single parenthood, cohesion, stress, family discipline, history of violence, problems at school, clinical disorders and violent peer relationships. The concurrence of school, sibling and dating violence was particularly noteworthy. The theoretical frameworks referred to can be grouped into psychological, communicational, criminological, sociological and broader integrative models (Ecosystemic, Phenomenological and Constructivist). No data was found on interaction patterns, coping strategies or social perceptions of CPV which may influence families immersed in these kinds of situations.

Published: April 2020

Identificar factores instruccionales específicos relacionados con progresos en comprensión lectora es esencial para optimizar el aprendizaje y orientar la intervención, especialmente en contextos de desventaja sociocultural o dificultades de aprendizaje. Este estudio pretende identificar patrones instruccionales de mediación eficaces en la explicación del progreso en comprensión. Se grabaron, transcribieron y analizaron sistemáticamente 82 sesiones-clase, y se registraron pautas de mediación relativas a diferentes procesos lectores. Los patrones de mediación fueron analizados mediante codificación y categorización del contenido con el programa Maxqdea-7. Fueron consideradas 19 categorías, que aglutinaron 178 unidades de información significativas (pautas/conductas de mediación). La muestra estuvo compuesta por 21 docentes y 821 estudiantes de tercero a octavo grado de Educación básica de escuelas públicas de Chile ubicadas en contextos deprivados. El progreso lector se midió con la prueba estandarizada CL-PT, aplicada al principio y al final del curso escolar. Los resultados permitieron identificar pautas específicas de mediación significativas en la explicación del progreso, especialmente el patrón M_17 (Mediación del uso de estrategias para la activación e integración de conocimientos previos) explicaba el 26% de la varianza (r = .55, p < .01; R2ajustado = .26, F(1, 19) = 8.19, p = .01). Se discuten las implicaciones educativas de estos resultados.   

Identifying specific instructional factors related to progress in reading comprehension is essential to optimize learning and guide intervention, especially in contexts of sociocultural disadvantage or learning difficulties. This study aims to identify effective mediational instructional patterns in the explanation of progress in reading comprehension. Teaching guidelines were systematically recorded in relation to different reading processes. Eighty-two sessions were recorded, transcribed and analyzed by coding and categorizing the content of the sessions through the Maxqdea-7 program. Nineteen categories were considered, which comprised 178 significant units of information (mediation guidelines). The sample consisted of 21 teachers and 821 students from third to the eighth grade of public schools of Chile located in deprived contexts. Reading progress was measured with the standardized CL-PT test, which was applied at the beginning and end of the school year. The results have allowed identifying mediation patterns with a significant relevance in the explanation of reading progress, especially the pattern M_P17 (Mediation of the use of strategies for the activation and integration of previous knowledge) managed to explain 26% of the variance in the progress (r = .55, p < .01; R2adjusted = .26, F(1, 19) = 8.19, p = .01). The educational implications of these results are discussed.
Las dificultades neuroevolutivas como categoría comprensiva de las dificultades de aprendizaje en niños con retraso del desarrollo: una revisión sistemática
Authors: Taboada Ares Eva María , Iglesias Souto Patricia María , López Gómez Santiago , Rivas Torres Rosa María
Published: April 2020

Un número considerable de estudiantes presenta dificultades de aprendizaje y bajo rendimiento académico, sin embargo su evaluación no siempre deriva en un diagnóstico concreto. Son categorizados como inmaduros, pero no se determinan ni la naturaleza ni las características de sus dificultades. El objetivo de este estudio fue identificar los dominios evolutivos afectados en niños con retraso del desarrollo (RD) con la finalidad de valorar el concepto de dificultades neuroevolutivas como categoría comprensiva y perfil de las dificultades generalizadas de aprendizaje. Para ello, se realizó una revisión sistemática en las bases electrónicas Medline, PsycINFO, WOS, Eric, Dialnet y CSIC y, tras aplicar los criterios de inclusión, se seleccionaron 18 artículos. Los resultados confirman que RD se utiliza como etiqueta diagnóstica para caracterizar a niños con retrasos significativos en uno o varios ámbitos del desarrollo, pero no existe una definición de consenso ni criterios específicos para su diagnóstico, y solo sería de aplicación a niños de corta edad. Los dominios afectados coinciden con funciones neuroevolutivas y, en su etiología, destacan factores de riesgo biológico y ambiental. Las dificultades neuroevolutivas abarcarían un amplio espectro de déficits con distintos niveles de gravedad que, al interactuar entre sí, dan lugar a una variedad de perfiles.

A considerable number of students have learning difficulties and low academic performance, yet their evaluation does not always lead to a concrete diagnosis. They are categorized as immature, but neither the nature nor the characteristics of their difficulties are determined. The aim of this study was to identify the developmental domains which are affected in children with developmental delay (DD) in order to assess the concept of neurodevelopmental difficulties as a comprehensive category and profile of generalized learning difficulties. To this end, a systematic review was carried out on the electronic databases Medline, PsycINFO, WOS, Eric, Dialnet and CSIC and, after applying the inclusion criteria, 18 articles were selected. The results confirm that DD is used as a diagnostic label to characterize children with significant delays in one or more developmental domains, but there is no definition of consensus nor specific criteria for its diagnosis, and it would only be applicable to young children. The affected domains coincide with neurodevelopmental functions, and biological and environmental risk factors stand out in their aetiology. Neurodevelopmental difficulties would encompass a wide spectrum of deficits with different levels of severity that, on interacting with each other, give rise to a variety of profiles.

Muchos estudios anteriores han discutido la influencia de factores extrínsecos (por ejemplo, hábitat) en el éxito académico de los niños de China occidental. El presente estudio se centró en cuatro factores no cognitivos, aspiración autopedagógicas, autoeficacia, motivación instrumentaly ansiedad, que puede afectar el logro de las matemáticas. El propósito de este estudio era investigar los mecanismos de cómo estos cuatro factores no cognitivos afectaron logro matemáticas. 5774 primaria los estudiantes del grado 4 º y 5 º en el oeste de China participaron en este estudio. Se construyó un modelo de mediación encadenado moderado. Los resultados mostraron que autopedagógicas aspiración positiva podía predecir logro matemáticas. Sin embargo, la ansiedad y motivación instrumental forman encadenado mediación entre autopedagógicas logro de aspiración y de las matemáticas y el logro de matemáticas negativamente prevista. Además, la autoeficacia desempeñó un papel moderado en la relación entre la aspiración de la autopedagógicas y la ansiedad.

Many previous studies have discussed the influence of extrinsic factors (e.g. living environment) on academic achievement of children from western China. The present study focused on four non-cognitive factors, self-educational aspiration, self-efficacy, instrumental motivation, and anxiety, which could affect mathematics achievement. The purpose of this study was to investigate the mechanisms how these four non-cognitive factors affected mathematics achievement. 5774 primary school students from 4th and 5th grade in western China participated in this study. A moderated chained mediation model was constructed. The results showed that self-educational aspiration could positively predict mathematics achievement. However, instrumental motivation and anxiety formed chained mediation between self-educational aspiration and mathematics achievement, and negatively predicted mathematics achievement. Besides, self-efficacy played a moderated role in the relationship between self-educational aspiration and anxiety.
Development and Validation of the Spanish Version of the Political Skill Inventory: A Measurement Invariance Test
Authors: Cepas González Rebeca , Ruiz-Zorrilla Blanco Paula , Gil Francisco , Antino Mirko
Published: April 2020

Introducción: El inventario de habilidades políticas (PSI, siglas en inglés) es una medida para calibrar cuatro dimensiones relacionadas con este constructo: la astucia social, la capacidad de influencia interpersonal, la habilidad para establecer contactos y la sinceridad aparente (Ferris, 2005).

Método: En el presente estudio, multi-muestra y multi-método, sendos análisis factorial exploratorio y confirmatorio se han llevado a cabo para desarrollar y testar las propiedades psicométricas de la versión española del PSI. Adicionalmente, se llevó a cabo un test de fiabilidad longitudinal y un análisis de invarianza relativo al género.

Resultados: Los índices alpha de Cronbach y omega revelaron un grado de fiabilidad satisfactoria. El análisis factorial exploratorio extrajo los cuatro factores de la versión original, tal y como ya ha sido reportado en otros estudios (N = 309). El análisis factorial confirmatorio confirmó que el ajuste de dicha estructura fue el mejor frente a los datos (N = 248).

Conclusiones: Con este estudio se añade evidencia al estudio de la invarianza de género y la estabilidad temporal de esta medida, mostrando que la versión española del PSI puede ser considerada una medida estable y válida a través del tiempo y relativa al género.

Background: The Political Skills Inventory (PSI) is a measurement tool for assessing four dimensions associated with political skills: social astuteness, interpersonal influence, networking ability and apparent sincerity (Ferris, 2005).

Method: In the present study, multi-sample and multi-method, we developed and analyzed the psychometric properties of the Spanish version of the (PSI), by performing both exploratory and confirmatory factor analyses. Additionally, a longitudinal reliability test and a sex factorial invariance test were performed.

Results: Cronbach's alpha and omega indices revealed satisfactory reliability and exploratory factor analyses extracted the four original factors as reported in other studies (N = 309). Confirmatory factorial analyses confirmed that the four-factor solution presented the best fit to our data (N = 248).

Conclusions: We add new evidence for time and sex invariance of the measure, showing that the PSI can be considered a stable and valid measure over time and across sex.
Ciberviolencia en las relaciones de pareja: una revisión sobre su metodología de investigación
Authors: Rodríguez Domínguez Carmen , Pérez-Moreno Pedro J. , Durán Mercedes
Published: April 2020

En los últimos años ha aumentado el interés por el estudio de la ciberviolencia en la pareja, sin embargo es necesario examinar la metodología de investigación que sustenta las evidencias obtenidas hasta el momento. Este artículo presenta una revisión sistemática de la literatura científica que analiza 30 instrumentos de medida de ciberviolencia en la pareja de adolescentes y jóvenes adultos utilizados a lo largo de estos años. Los principales resultados muestran una elevada pluralidad metodológica, conceptual y terminológica, observándose un reducido número de instrumentos con suficientes garantías psicométricas. Predominan los trabajos de procedencia estadounidense y, entre los instrumentos aplicados en muestras españolas, destaca una infrarrepresentación de indicadores de ciberviolencia de tipo sexual, lo que limita la comprensión de esta problemática. Esta investigación aporta información sobre el estado actual en el estudio de la ciberviolencia en la pareja y pone de relieve deficiencias metodológicas en la construcción del conocimiento en este campo de estudio. Este trabajo permite una mejor comprensión de la disparidad de resultados señalada por investigaciones previas, especialmente referidas a prevalencia, frecuencia y diferencias de género en este tipo de comportamientos violentos, además de sentar las bases para abordar el fenómeno desde el rigor científico.

The interest for the study of the cyber dating abuse has increased in the last years; however, it is necessary to examine the research methodology that supports the evidence obtained so far. This paper presents a systematic review of the scientific literature that analyzes 30 measuring instruments of cyber dating abuse in adolescent and young adults used along these years. The main results show a methodological, conceptual and terminological plurality, observing a small number of instruments with sufficient psychometric guarantees. The instruments come mostly from the United States, and of the instruments applied to Spanish samples, few include indicators of sexual cyber dating abuse, which limits the understanding of this problem. This research provides information on the current status of the study of cyber dating abuse and highlights methodological shortcomings in the construction of knowledge in this field of study. This study allows a better understanding of the disparity of results indicated by previous research, especially referring to prevalence, frequency and gender differences in this type of violent behavior, as well as laying the foundations for addressing the phenomenon from scientific rigor.
Regulation of cognition: Validation of a short scale for Portuguese first-year university students
Authors: Bártolo-Ribeiro Rui , Peixoto Francisco , Casanova Joana , Almeida Leandro
Published: April 2020

La calidad del aprendizaje en la Educación Superior depende, especialmente, de las habilidades de los estudiantes para regular su cognición. Esta regulación requiere habilidades cognitivas y metacognitivas, así como dimensiones motivacionales. Dada su relevancia en el rendimiento académico y el desarrollo de habilidades para el aprendizaje a lo largo de la vida, es importante aumentar la investigación en el campo. Este estudio pretende adaptar y validar una versión abreviada da dimensión Regulación de la Cognición del Metacognitive Awareness Inventory para estudiantes universitarios portugueses de primer año. Se empleó una muestra de 360 estudiantes y se identificó una estructura tridimensional (Planificación, 4 ítems; Estrategias, 7 ítems; y Monitoreo y evaluación, 7 ítems) con un factor de segundo orden (Regulación de la cognición). Los valores de consistencia interna de la escala reducida son aceptables para una escala de autoinforme y las correlaciones con el logro académico al final del primer año de la universidad garantizan su validez predictiva. Esta versión abreviada para medir la regulación de la cognición puede usarse en investigación junto con otros instrumentos en estudios más amplios y puede funcionar como una herramienta de diagnóstico para ayudar a los estudiantes en los desafíos de aprendizaje de la enseñanza superior.

The quality of learning in Higher Education is particularly dependent on students' skills in regulating their cognition. This regulation requires cognitive and metacognitive skills as well as motivational dimensions. Due to its relevance in explaining students' academic achievement and developing lifelong learning skills, it´s important to increase research in the area. This study aims to adapt and validate a short version of the Regulation of Cognition of Metacognitive Awareness Inventory to first-year Portuguese university students. A sample of 360 students was considered and was identified a three-dimensional structure (Planning, 4 items; Strategies, 7 items; and Monitoring and evaluation, 7 items) with a second-order factor (Regulation of Cognition). The internal consistency values of the reduced scale are within the acceptable parameters for a self-report scale and the correlations with academic achievement at the end of the first year of the university guarantee the predictive validity of the scale. This short version of regulation of cognition measure allows its use in research with other instruments in larger studies and can function as a diagnostic / screening tool to help students in higher education learning challenges.
El fenómeno del sexting entre los adolescentes españoles: prevalencia, actitudes, motivaciones y variables explicativas
Authors: Gil-Llario María Dolores , Morell-Mengual Vicente , Giménez García Cristina , Ballester-Arnal Rafael
Published: April 2020

El sexting es un fenómeno que consiste en el envío y la recepción de fotos, videos y/o mensajes de texto de naturaleza sexual a través de smartphones. Como en todos los demás países desarrollados, se está convirtiendo en una práctica cada vez más popular entre los adolescentes de España. Al tratarse de un fenómeno muy reciente todavía no existen muchos trabajos que hayan estudiado con profundidad su entidad y sus factores implicados. Por tanto, los dos objetivos de este estudio fueron determinar la prevalencia y analizar las variables explicativas del inicio y del mantenimiento de las conductas de sexting. La muestra estuvo formada por 784 adolescentes españoles (52% chicos y 48% chicas) con edades comprendidas entre los 12 y los 18 años (M = 14.44; DT = 1.61). Los resultados indican que el 24.4% ha practicado sexting en alguna ocasión, realizando esta conducta con una media de 2.32 personas (DT = 2.70). El análisis de regresión reveló que las actitudes positivas hacia el sexting, el nivel de impulsividad, la edad, ser hombre y el mantener una relación de pareja son variables que predicen la práctica del sexting. Estos resultados son muy importantes en la elaboración e implementación de estrategias preventivas que enfaticen el uso responsable de las TICS y las redes sociales.

Sexting is a recent phenomenon in which people send and receive photos, videos and/or text messages of sexual nature via smartphones or similar devices. Similar to other developed countries, it is becoming an increasingly popular practice among teenagers in Spain. Provided it has appeared very recently, scarce research has focused on examining in-depth factors involved in its initiation and maintenance. Therefore, the two main aims of this study were to determine its prevalence and to analyse the explanatory variables of the sexting behaviours. The sample consisted of 784 Spanish adolescents (52% boys and 48% girls) between 12 and 18 years of age (M = 14.44; SD = 1.61). The results showed that 24.4% have practised sexting at some time, with an average of 2.32 people (SD = 2.70). The regression analysis revealed that positive attitudes towards sexting, level of impulsivity, age, being male and having a partner are variables that predict engagement in sexting. These results are very important for designing and implementing preventive strategies that emphasise the responsible use of ICTs and social networks.

Published: April 2020

El objetivo de este trabajo es evaluar empíricamente la eficacia de un programa de intervención con mujeres víctimas de violencia de género. El programa en conjunto se enmarca dentro de las Terapias Contextuales, específicamente se ha utilizado la Psicoterapia Analítica Funcional, combinada con la Terapia de Aceptación y Compromiso y la Activación Conductual. Se ha llevado a cabo en formato grupal, durante 11 sesiones de 2 horas cada una. Participaron un total de 21 mujeres (de una media de edad de 45 años), que habían sufrido violencia física y/o abuso emocional por parte de sus parejas, en diferente grado e intensidad, y en diferentes momentos en sus vidas. Se ha utilizado un diseño intragrupo con medidas pre-post. Se realizaron tres grupos de tratamiento en diferentes ciudades con 6 a 8 mujeres cada uno. Para medir la intervención se ha aplicado el cuestionario Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). Los resultados han mostrado una disminución estadísticamente significativa en la severidad del malestar, han disminuido los indicadores de riesgo de suicidio, y han mejorado las conductas problemáticas dentro y fuera de las sesiones, además de incrementarse la apertura hacia los demás. Se discute la utilidad de las terapias contextuales para mejorar la calidad de vida de mujeres maltratadas, y su utilidad de aplicación en grupos en las instituciones públicas.

The goal of this study is to empirically evaluate the efficacy of an intervention program with women victims of gender violence. Specifically, Functional Analytical Psychotherapy has been used, combined with Acceptance and Commitment Therapy, and Behavioral Activation. It has been carried out in group format, during 11 sessions of 2 hours each. A total of 21 women participated (an average of 45 years-old), who had suffered physical violence and/or emotional abuse by their partners, with different degrees and intensity, and at different moments of their lives. An intra-group design with pre-post measures was used. Three treatment groups were carried out in different cities with 6 to 8 women each one. To measure the intervention, the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) questionnaire was applied. The results has shown a statistically significant decrease in the severity of discomfort, decreased suicide risk indicators, improved problem behavior inside and outside sessions, and increased openness to others. The usefulness of contextual therapies to improve the quality of life of battered women and their usefulness for application in groups in public institutions are discussed.

Considering their potential to reduce Greenhouse Gas (GHG) emissions, the Energy Performance of Buildings Directive (EPBD) recast set the objective that by December 2020 all new buildings shall be nearly Zero-Energy Buildings (NZEB). This study gives an overview of those buildings that follow the Passive House (PH) certification standard in Spain, focusing on the analysis of some fundamental driving forces (population, Gross Domestic Product (GDP), climatic zones, Energy Performance Certificates (EPCs) and building construction/refurbishment specialists) that may explain the regional distribution of these type of buildings. Main conclusions illustrate that the “climate zone effect” may have a relevant effect on their geographical location. In contrast, the evolution of the real estate market is not related with their location, and that despite the GDP and the population having a certain effect, the number of PH Constructors is found to be a fundamental variable in explaining the number of buildings in Spanish regions. Therefore, a policy destined to raise awareness and to improve the technical training of these specialists and to extend this standard (or similar ones) to new and refurbished multifamily houses in big cities, may be fundamental to increase the number of NZEBs in this country.

Keywords: nearly Zero-Energy Buildings (NZEB); Passive House (PH); Energy Certification; Spanish Building Code ; Energy performance; Climate Change.
WHAT DRIVES PROMOTIONS IN INFRASTRUCTURE COMPANIES?
Authors: ANTA CALLERSTEN CARLOS , ARROYO BARRIGÜETE JOSE LUIS
Published: April 2020

This technical note summarizes the main results of Anta Callersten and Arroyo-Barrigüete (2019) on factors affecting the promotion of employees in an infrastructure company. Based on a sample of 5,150 employees, the conclusion is that salary revisions of less than 10% are almost exclusively linked to performance, while the highest salary increases are usually assigned to employees with higher potential. This result seems compatible with the general theory of remuneration, in which the annual variable remuneration rewards the results of each year and fixed salary revisions (promotions) respond to the development of the employee's professional career.
Keywords: Human resources, performance, potential, wages.

Published: April 2020

Gypsum is a material that has been widely used since ancient times in building and industrial construction. Due to the great development of prefabricated construction in the last years, diverse authors have tried to improve the properties of plaster panels and boards through its composition variations. The aim of this study is to determine what type of fibre, among the most used in plaster mixing ones, presents better properties to be used in prefabricated elements. For this, five types of fibres were used: two natural (wood and straw) and thee synthetic (glass, basalt and polypropylene), performing all the tests according to the standard UNE-EN 132792:2006. The conclusions show after statistical analysis that fiberglass presents better results for its application in the production of gypsum prefabricated panels and boards.

Key words: gypsum-based composite, natural fibre, synthetic fibre, prefabricated.

Identité professionnelle et agressions dans les métiers spécialisés de la construction et du secteur manufacturier au Québec
Authors: Cloutier Geneviève , Marchand Alain
Published: April 2020

Cette étude vise à mieux comprendre le lien entre identité professionnelle et agressions fondées sur le sexe et le genre dans les métiers spécialisés de la construction et du secteur manufacturier au Québec. Une limite importante dans la littérature s’avère être l’absence d’étude portant sur l’identité professionnelle et sa fragilisation. L’identité professionnelle englobe l’ensemble des pratiques et des coutumes qui procure une reconnaissance aux travailleurs dans l’exécution de leurs tâches, en plus d’une affirmation d’eux-mêmes au travail (Ashforth et Mael, 1989).

Des questionnaires ont été distribués dans sept chantiers de construction et dans quatre établissements manufacturiers, pour un total de 282 répondants. Les résultats des analyses multiniveaux, en considérant les variations entre les 54 équipes de travail, ont suggéré un effet direct de la déviance interpersonnelle sur les agressions psychologiques. Les résultats ont aussi révélé que l’identité professionnelle et sa fragilisation prédisposent aux agressions, notamment une faible intégration des différences dans l’équipe, ainsi qu’un soutien social insuffisant. Tandis qu’une utilisation des compétences plus forte et une faible préoccupation pour le groupe s’associent aux agressions sexuelles dans les métiers spécialisés. De plus, une faible estime publique du métier s’associe à des agressions physiques, alors que des demandes élevées au travail et l’insécurité d’emploi s’associent à des agressions psychologiques. Enfin, les modèles multiniveaux ont associé le fait d’être une femme aux agressions physiques et sexuelles.

Les conclusions de cette recherche corroborent l’importance d’agir sur les dimensions identitaires afin de réduire les agressions, particulièrement en misant sur l’inclusion des travailleurs dans les processus innovants et sur une plus grande ouverture de leur part aux nouvelles idées. Au niveau de la culture des métiers spécialisés, il serait également judicieux de privilégier les valeurs dites plus féminines basées sur la collaboration, l’empathie et le soutien.
Occupational Safety and the City: Licensing Regulation and Deregulation in the Taxi Sector

Many large cities in North America have jurisdiction over licensing rules that shape the employment and health conditions of ride-hail and taxi drivers. Yet there is a lack of research on the role of licensing agencies relating to the occupational health and safety (OHS) of taxi drivers. Most taxi and ride-hail drivers in Canada are self-employed workers and are, by default, exempt from OHS and worker compensation laws. Additionally, municipal licensing regimes in Canada and the US have undergone various changes as a result of pressures from new platform-based ride-hail services, like Uber and Lyft.

The analysis is part of a larger study on the health and safety conditions faced by ride-hail drivers. The research approach adopted a multi-level sampling and analysis strategy with the aim of connecting taxi drivers’ everyday work experiences to company and sector practices, and with various regulatory arenas, including municipal licensing, taxation and car insurance. In this paper, the analysis draws from in-depth interviews at these different levels: with taxi and ride-hail drivers, with taxi and ride-hail managers, and with key informants in government, law, insurance, tax and elsewhere.

The paper identifies features and impacts of municipal deregulation in the era of on-demand taxi services, focusing on a large Canadian city in a province where municipal authorities regulate the vehicle-for-hire sector. The research identified regulatory changes that included removing centralized taxi vehicle inspections, cancelling mandatory driver training, and instigating rapid changes to competition in the taxi workforce by issuing unlimited numbers of ride-hail licenses. Our analysis indicates that regulatory changes adopted by the city administration have compounded work vulnerabilities and hazards for taxi drivers, while extending hazardous conditions to ride-hail drivers. These hazards suggest the need for interventions at a range of levels, actors and agencies, rather than solely by city licensing officials.
