Research on the Polish short version of the Self-Regulation Scale: a study across adolescents and adults with three independent samples
Authors: Rodzeń Wojciech , Gajda Maja 
Published: December 2024

BackgroundSelf-regulation is the ability to make and execute plans, manage emotions, and control behavior in order to achieve goals. Self-regulatory skills are crucial for proper psychosocial functioning. A higher level of self-regulation skills helps build more supportive relationships and is related to higher psychological well-being. Poor self-regulation is associated with a higher probability of falling into addictions and appears to be the main reason behind a wide range of behavioral problems.Participants and procedureThe present study aimed to evaluate the psychometric properties of the Polish short version of the Self-Regulation Scale (sSRS) based on the 26-item Self-Regulation Scale. The following validity indicators were used: the Rosenberg Self-Esteem Scale, the Positive Orientation Scale, the Satisfaction with Life Scale, the State-Trait Anxiety Inventory, the General Self-Efficacy Scale, and the Buss-Perry Aggression Questionnaire. The study was conducted using a 12-item sSRS with a total of 1,525 participants from three independent studies.ResultsThe obtained higher-order factor model confirmed the three-factor structure of self-regulation, containing three main as-pects: emotional (propensity for impulsivity and intense, negative emotional states), cognitive (ability to make and execute plans), and behavioral (fidgetiness and being in movement, as well as difficulties in focusing and directing attention). Two higher-order factors were added to the behavioral dimension: hyperactivity and behavioral attention.ConclusionsThe results of the exploratory and confirmatory factor analysis (EFA, CFA) as well as the obtained values of reliability and validity coefficients indicate satisfactory psychometric properties of the sSRS and its usefulness in further empirical research.

PurposeThe objective of the present manuscript was to analyse the flow of play in high-level women’s volleyball by sequencing game complexes per set.MethodsThe sample analysed 135 matches played in the 2021/2022 Brazilian Women’s Superliga, with the number of matches analysed ranging from 14 and 25 matches for all teams participating in the championship. Eigenvector Centrality and Social Network Analysis conducted the connectivity and specificity of relationships as, and inferential analysis was performed using the chi-square test with a Monte Carlo correction.ResultsThe results showed that the highest eigenvalues were for the continuity effect, except for complex 0. Regarding the continuity effect, the eigenvalues in the first four sets were higher for complexes III, IV, and V. In the fifth set, the highest eigenvalues were close between complexes II, III, IV, and V for the continuity effect. Furthermore, the results indicated that there was no association between the sequencing of game complexes and the set played (χ² = 2470.01 and = 0.34, <i>p</i> = 0.272), nor between the number of complexes and the set played (χ² = 17.63 and = 0.03, <i>p</i> = 0.346).ConclusionsIn conclusion, women’s volleyball presents gameplay strategies to sustain play, promoting game continuity, regardless of the set played. The number of game complexes required to secure a point varies between two and three game complexes. Coaches should consider the dynamics in women’s volleyball matches, preparing teams for less risky and more continuous play.

Enfoque interseccional en un protocolo para el análisis del cubrimiento periodístico de feminicidios
Authors: Da Silva Maria Terezinha , Bertasso Ribeiro Daiane 
Published: December 2024

Introducción y objetivo. El artículo parte del supuesto de que la violencia contra las mujeres -que puede derivar en feminicídios- es un problema público que requiere que las políticas de Estado sean pensadas desde una óptica interseccional (Crenshaw, 2004; Collins y Bilge, 2021). Desde esta perspectiva, nuestro objetivo es comunicar un protocolo de cubrimiento periodístico de feminicidios. Metodología. A partir de lecturas teóricas y empíricas sobre el feminicidio y los estudios de género desde una perspectiva interseccional, proponemos un protocolo de análisis del cubrimiento de los feminicidios, compuesto por siete ejes de lectura. Seis de ellos están relacionados con crímenes específicos reportados por la prensa y pretenden identificar información sobre: (1) el medio, la materialidad y la localización; (2) el crímen; (3) la víctima; (4) el agresor; (5) las fuentes de información; y (6) la estratificación sexual. El séptimo eje se refiere a la lectura de (7) noticias generales, no relacionadas a casos específicos, pero que abordan el tema del feminicidio, cuestionando aspectos que cruzan los otros ejes, principalmente si la violencia contra las mujeres es discutida como un problema público y si hay elementos identificables de marcadores interseccionales. Resultados y conclusiones. El análisis permite percibir la utilidad del protocolo en la búsqueda de marcadores sociales interseccionales. El protocolo permite analizar los límites del cubrimiento periodistico con respecto a la superposición de violencia y opresión en los casos de feminicidio. Al mismo tiempo, permite ver aspectos potencialmente relevantes para un tratamiento más adecuado del tema por parte de la prensa.

В статье приведены результаты исследований физико-механических свойств материала, полученного при металлургической плавке по технологической схеме создания сплавов на базе минерального сырья Якутии. Выявлено, что сплав по физико-механическим свойствам наиболее близок к категории углеродистых инструментальных низколегированных сталей согласно ГОСТ 1435–99. Мелкозернистая однородная структура полученного сплава свидетельствует об улучшенном прочностном комплексе физических и механических свойств данного материала. Значения предела прочности и твердости материала соответствуют показателям, характерным для качественных углеродистых сталей после нормализации. Доказана целесообразность использования железных руд осадочного происхождения из рудопроявления «Мэнэ-Алдан» при разработке инструментальных сталей и сплавов.
