Future horizons in the analysis of technical-tactical performance in women's football: a mixed methods approach to the analysis of in-depth interviews with professional coaches and players.

Introduction: Scientific knowledge about the criteria that determine success in women's football is beginning to develop. Methods: This study was carried out with the aim of detecting regularities in the offensive success in elite women's football, as well as carrying out an interrelational analysis of linked behaviors, based on in-depth interviews with professional coaches and players. Eight in-depth interviews were conducted with professional Spanish coaches and players. The interviews were analyzed by indirect observation from a process of "quantitizing," through the construction of an indirect observation ad hoc instrument. The segmentation of the transcription of the interviews was carried out in textual units, and the creation of a matrix of codes. Two types of analysis were performed: first, a lag sequential analysis (LSA) was performed and, then, a polar coordinates analysis (PCA), which allowed to find, respectively, a wide number of established communicative patterns with offensive performance in women's football, as well as an interrelational map between the established codes. Results: The results obtained allowed us to suggest a statistically significant association between success in women's football and criteria such as the physical characteristics of a particular player, the individual action space, the duration of the attack, the type of dynamic start, individual and collective technical and tactical aspects, decision making and the type of attack used. Discussion: Based on these results, the influence of these criteria on performance in women's soccer can be studied in future studies. In addition, with the aim of increasing the validity of these conclusions, new studies on this subject may be carried out following strategies such as the Delphi Method.

Systematic Observation of Emotional Regulation in the School Classroom: A Contribution to the Mental Health of New Generations.

Emotional regulation is a developmental milestone, as it promotes well-being throughout life. Children between 10 and 12 years old are expected to reach capacities that allow them to regulate themselves emotionally, the school context being a natural setting for this challenge. With the objective of analyzing the forms of expression and regulation of emotions that are observed in the school classroom, this research was conducted through a mixed methods study that systematically observed nine classes during five sessions each. The design was Nomothetic, Follow-up and Multidimensional; the observations were recorded on audio and in person and were later transformed into data by coding them according to an ad hoc designed instrument. The concordance of the records was evaluated, a sequential analysis of delays (GSEQ5) was performed to detect regularities and existing sequences, and a polar coordinate analysis (HOISAN) observed the relationships between the categories. Finally, the presence of multiple cases was detected. The results detail the ways in which different actors express emotions and interact, regulating the emotions of other people. The results are discussed based on the need to foster educational intentionality and allow students' emotional self-regulation.

New insights into the behavioral structure of Pikler educators: An application of T-pattern detection and analysis with THEME.

Introduction: The recent generalization of early childhood schooling has given rise to a need for the development of rigorous, specific training programs aimed at early education professionals (0-3 years of age). This work emanates from the unique nature of Pikler-Lóczy education as a reference for early childhood education centers, and its expertise in providing quality care in an everyday classroom situation. The aim of the study is to use T-pattern detection and analysis, within the framework of observational methodology, to identify relevant aspects of the choreography followed by Pikler educators during breakfast, and thus provide substantial material with a view to creating a training plan. Methods: Two expert educators in Pikler-Lóczy education were directly and systematically observed in their own classrooms, following a nomothetic, follow-up and multidimensional design. The observation instrument underwent a molarization process so that the detected elements would be more significant and understandable for novice educators. Results: Using THEME, the invariant aspects of the educators' behavior were analyzed. The significance level for the critical interval was the THEME default (α = 0.005). The results show: on the one hand, changes expected in T-patterns in accordance with the observation instrument molarity; and on the other hand, stability in terms of the comparison between the two educators. Discussion: These results help us to identify the complex structure of the breakfast choreography, and how educators establish interaction with children. In addition to specific issues pertaining to Pikler-Lóczy education, the conclusions highlight the advantages of using T-pattern analysis within the framework of observational methodology, in order to dissect a mealtime routine in its natural context, and explain components of early childhood education intervention that satisfy basic childhood needs. This constitutes a starting point from which to generate instructive material for the training of professionals working in early education.

T-pattern detection in the scientific literature of this century: A systematic review.

Introduction: Scientific literature contains mainly systematic reviews focused on substantial aspects, but there are also approaches that have combined both substantial and methodological aspects, which is our preferred option since it undeniably adds value. The aims of this study were: (1) to carry out a systematic review of the literatura on T-Pattern analysis (TPA), and (2) to explore the possible contribution of mixed methods research to the integration of qualitative and quantitative elements on a synthesis level. Methods: Based on PRISMA guidelines, searches were carried out in the Scopus, PsycINFO, and Web of Science databases. The general search syntax was: "THEME" AND ("T-Patterns" OR "T Patterns") carried out in title, keywords and abstract. In addition, we included empirical articles on THEME and T-Patterns collected in other sources based on citations in several empirical works and consultations with different authors. This selection process resulted in 125 primary documents making up this systematic review. Results: The results showed that the detection of structures in behavior patterns forms a nexus between studies carried out in very diverse fields and contexts. Most studies are observational, whilst the applicability and power of T-Pattern detection are extraordinary. It allows the researcher to go deeper in a robust analysis that responds to the integration of qualitative and quantitative elements which constitutes the leit motive of mixed methods; and also to discover the deep, hidden structure that underlies the respective databases, regardless of the methodology used in each study. The possibilities in assigning parameters notably increase the options for obtaining results and their interpretation. Discussion: It is relevant the extraordinary strength and applicability of T-pattern detection. There is a high presence of T-pattern detection and analysis in studies using observational methodology. It is necessary commit to consolidating the methodological analysis of selected works, as taking individual and collective responsibility for improving methodological quality of TPA studies, taking advantage of the resources provided by the THEME program.

Methodological procedure based on quantitizing/liquefying: a case study to assess work climate in an emergency department.

Introduction: In the assessment of health organizations, results-based indicators are mainly used, with no consideration of internal work dynamics. This type of assessment forfeits much of the rich, useful information needed to make decisions on improving the organization. In order to address this, a rigorous procedure based on mixed methods is laid out here on gathering, analyzing, and interpreting data associated with the implementation process. Methods: A 55-year-old doctor was selected at random from among the staff who volunteered to be interviewed at the emergency department at a public hospital located in southern Spain for an interview. Qualitative data obtained from the in-depth interview (indirect observation) were progressively systematized (liquefied and quantitized) based on a theoretical framework until a code matrix was obtained, without losing or distorting any information. Afterwards, data quality was controlled using Cohen's kappa (κ) coefficient. A quantitative polar coordinate analysis was then carried out using the free software HOISAN (v. 1.6.3.3) to obtain robust results, vectorizing the relationships between codes and specifying whenever such relationships were statistically significant (and if they resulted in behavior activation or inhibition). Finally, a supplementary quantitative and qualitative assessment was carried out. Results and discussion: The proposed method was applied to the needs assessment of teams in order to evaluate that work climate in the hospital's emergency department Health Services of a hospital. Data quality control yielded an adequate result (κ = 0.82). Significant activation and inhibition of behaviors occurred, both prospectively and retrospectively. For instance, We seek to understand the needs of our clients and We readily adapt to new circumstances showed a significant activation (vector length = 3.43, p < 0.01) both prospectively (Zsum = 0.48) and retrospectively (Zsum = 3.4).An adequate method to obtain detailed information about group dynamics in a work environment is presented, based on an in-depth interview. Practical applications for implementations to improve the functioning of organizations are presented.

A systematic review on lecturing in contemporary university teaching.

Introduction: Articles published in scientific journals, concerning the present and future of the lecture format in university education in the twenty-first century are framed within organizational settings that drive teaching methodologies in line with educational policies. The following two research questions have arisen from articles in which debate the continuity of this teaching modality and propose improvements of a different nature: (1) Is there an interest in renovating the lecture format among the international research community whose remit is university teaching methods? and (2) What improvements to the lecture format do the reviewed articles suggest, within the framework of the communicative matrix of interactive learning? Method: We have carried out a systematic review guided by the PRISMA approach, emphasizing the interest in methodological conceptual commitment, paying attention to documents published in journals with an impact factor. The search strategy was applied homogeneously in three databases: ERIC, PsycInfo, and Web of Science, following the systematic process of inclusion/exclusion. Results: Forty-five articles were selected with a range of 0-78 quotations, from different fields of knowledge and five continents; 12 articles are from journals with a JCR impact factor. The journal articles cover communicative (21), cognitive (13) and active-practical perspectives (11); the predominant governing aim of the analyzed improvements is connected with the attendees' academic performance results (24); the reviewed studies belong mainly to the quantitative paradigm (42). The considerations derived from the results (45) cover formative, technical and/or critical aspects. Discussion and conclusions: Whilst positively valuing all these efforts promoted by the European Higher Education Area, we have also verified the lack of contributions in line with our concerns that embrace the need to develop an in-depth conceptualization, supported by a methodology that is sensitive to the complexity of the oral communication format between an expert actor and non-specialized actors who wish to connect and collaborate with the expert in the production of knowledge.

Implementation and evaluation in low intensity intervention programs from the CONNECT perspective of mixed methods: Application in a case of an autistic child.

There has been a comprehensive development over the last few years of low intensity intervention programs that are implemented within a user context and that are made up of everyday life activities, and it has been necessary to adapt the necessary methodological channels in order to guarantee an adequate resolution pathway. The mixed method perspective offers a suitable framework, and observational methodology - in itself considered mixed method - is appropriate for studying the implementation and evaluation of low intensity intervention programs, allowing the development of the QUAL-QUAN-QUAL stages that correspond to the connect integration pathway of mixed methods. In this work it was applied to a single case, in a low intensity intervention, retrieving valuable information obtained, but systematizing it and applying quantitizing to the qualitative data that was treated quantitatively in a rigorous manner. The aim was to analyze the psychotherapist-patient interaction in psychoanalytic psychotherapy, in which we sought to identify which of the therapist's techniques stimulated actions of reciprocal social interaction in the child, and which techniques inhibited non reciprocal social interactions. The observational design was nomothetic, follow-up, and multidimensional. The patient was a 4-year-old boy with a diagnosis of severe autism spectrum disorder. We used an ad hoc observation instrument combining a field format and a category system. Interobserver agreement was analyzed quantitatively by Cohen's kappa using the free QSEQ5 software program. Polar coordinate analysis was carried out using the free program HOISAN 2.0. Polar coordinate analysis allows us to obtain an inter-relational map of the connections detected between focal behavior established in each case and the different categories. The results provide objective evidence - backed up by the application of polar-coordinate-based data analysis - that within a framework of psychoanalytic psychotherapy, the techniques of "verbalization" and "vocalization" significantly activate reciprocal social interaction behaviors and inhibit non-social reciprocal behaviors in a child with severe autism spectrum disorder with no language. On the other hand, direct gaze promotes the child's withdrawal. The results are of key importance as they show the therapist behaviors most useful for promoting social interaction in a child with severe autism.

Emotional Self-Regulation in Everyday Life: A Systematic Review.

Emotional self-regulation in childhood and adolescence constitutes a growing interest in the scientific community, highlighting in recent years the need to observe its development in their daily life. Therefore, the objective of this systematic review is to characterize publications referring to the development of emotional self-regulation of people under 18 years-old, in natural contexts. Based on the PRISMA guidelines, searches are carried out in the Web of Science, Scopus and PsycINFO databases, and in Google Scholar until May 2020. After reviewing the full text of 376 publications, 14 works are selected that are observed in their extrinsic, substantive and methodological characteristics based on the GREOM and MQCOM guidelines, by two independent evaluators. Most of the studies correspond to the last 20 years, increasing the interest in observing older children, in interaction with adults and/or in different cultures. They apply mixed methodologies, not always ascribing to a low intensity design. Strengths are observed regarding the collection and analysis of the quality of the data; and weaknesses related to the failure to record the duration and sequence of behaviors, highlighting the use of guidelines as guides for future research.

Análisis del combate en la iniciación al karate: un ejemplo de utilización de árboles de decisión en metodología observacional / Análise do combate na iniciação ao karatê: um exemplo do uso de árvores de decisão na metodologia observacional / Combat analysis in initiation to karate: decision trees in observational methodology

El presente trabajo persigue delimitar el desempeño técnico-táctico en combate en la iniciación al karate y mostrar las posibilidades de aplicación de la técnica de análisis de árbol de decisión en metodología observacional. El muestreo observacional ha ascendido a 887 acciones técnico-tácticas ofensivas realizadas en 40 combates por participantes de la franja de 8-9 años de edad. El instrumento de observación se ha introducido en el seno del softwarede registro y codificación, Lince. La calidad del dato ha quedado garantizada, por un lado, mediante un procedimiento de concordancia inter-observadores a partir del coeficiente Kappa de Cohen y, por otro lado, por un diseño de generalizabilidad. Se han realizado dos árboles de decisiónutilizando dos algoritmos diferentes (CHAID y CART). Los resultados obtenidos con ambos algoritmos coinciden en señalar como mejor predictor de la “zona del cuerpo a la que se dirige la técnica” a la dimensión “segmento”; pero se diferencian en el segundo mejor pronosticador: dimensión“grupo de técnica” mediante el algoritmo CHAID,y dimensión “técnica detallada” con el algoritmo CART.

This work analyze the technical-tactical performance in combat in the initiation to karate and show the possibilities of application of the decision tree analysis technique in observational methodology. The observational sampling is made up of 887 offensive technical-tactical actions executed in 40 combats by participants of the 8-9 age group. Regarding the recording and coding process, the observation instrument has been introduced in the software LINCE. The quality of the data has been guaranteed bymeans of an inter-observer concordance procedure based on Cohen's Kappa coefficient and by a design of generalizability. Two decision trees have been made using two different algorithms (CHAID and CART). The results obtained with both algorithms coincide in pointing out the "segment" dimension as the best predictor of the "body area to which the technique is directed";but they differ in the second best forecaster: dimension "technique group" through the CHAID algorithm,and "concrete technique" dimension with the CART algorithm.

The Pick-and-Roll in Basketball From Deep Interviews of Elite Coaches: A Mixed Method Approach From Polar Coordinate Analysis.

Pick-and-roll is the most widespread cooperative action among high-level basketball teams and the most applied strategy by coaches to gain an advantage over the rival team. During pick-and-roll, opposing teams perform antagonistic actions based on goals that are expressed in offensive and defensive tactics. The aim of this study is to examine the approaches of high-level coaches on the offensive and defensive dynamics emerging in matches of a basketball elite team during an entire season of the Spanish Asociación de Clubes de Baloncesto (ACB) league. To this end, we used a mixed-methods approach based on systematic observation of verbatim transcripts of interviews conducted with six high-level coaches about the pick-and-roll dynamics that emerged in matches of the Unicaja Málaga team during an entire season of the ACB league. The observational design was nomothetic, punctual, and multidimensional. The choice of this methodology is justified since we developed an ad hoc indirect observation tool to evaluate the coaches' perspective on this dynamic. Once the intra-observer reliability of the instrument was confirmed, we performed a polar coordinate analysis to identify the significant relationships between the coaches' evaluations and the offensive and defensive pick-and-roll elements that supported such verbal behaviors. The results highlight the presence of various offensive and defensive aspects of pick-and-roll (n = 2224) emerging in the Unicaja team that were significantly associated with positive and negative evaluations of the coaches. The interview confirms that coach 1 and his staff were less confident in options that pick-and-roll offer, which is also reflected in the record of screens made and simulated, than coach 3. This study shows that the application of mixed methods, by analysis of the polar coordinate of the coding carried out on responses of a systematized interview, has proven to be an effective strategy in obtaining relevant information on the expert knowledge of the elite coaches on the influence of pick-and-roll on tactical actions in basketball.

A Log-Linear Analysis of Efficiency in Wheelchair Basketball According To Player Classification.

Within the framework of observational methodology, we conducted a log-linear analysis to study efficiency in relation to players' functional ability in wheelchair basketball by analyzing associations between the position of the last pass before a shot, a shot position, and a shot result (favorable or unfavorable). The observation sample contained all offensive sequences ending in a shot by the US men's wheelchair basketball team, who won the gold medal at the 2016 Paralympic Games in Rio de Janeiro. Data were annotated and coded in the Lince software program and their reliability confirmed by measuring interobserver agreement using Cohen's kappa statistics. Log-linear modeling showed that the models generated to explain offensive sequences ending in a shot by players with greater functional ability were closest to models observed for professional basketball players and were the only models to show significant effects in terms of efficiency.

LINCE PLUS software for systematic observational studies in sports and health.

This paper aims to offer a free software program, LINCE PLUS, suitable for systematic observational studies in sports and health, conducted in natural contexts such as training, education or psychology. Using one or several videos simultaneously, different parameters such as behaviors, decision-making or strategies can be analyzed. The software includes several functionalities for studies that researchers need to utilize throughout the observational study process. Collaborative work can be accomplished by using simultaneous videos and multiple observers. The results of all research conducted by LINCE PLUS are offered inside the application in real time, enabling common calculations or including specific analysis with R language without the need for any other external tool. Moreover, LINCE PLUS shows the results of each study with interactive charts or, if needed, it exports the data to specific data analysis software programs (e.g., SAS, Excel, Theme, GSEQ 5, Hoisan). We include examples of sports and health studies that have been conducted with LINCE PLUS to show the suitability of this software program.

Coping strategies patterns to buffer the psychological impact of the State of Emergency in Spain during the COVID-19 pandemic's early months.

Coping style represents the cognitive and behavioral patterns to manage particular demands appraised as taxing the resources of individuals. Studies report associations between certain coping styles and levels of adjustment of anxious symptomatology and emotional distress. The main objective of this study was to analyze behavioral co-occurrent patterns and relationships in the coping strategies used to deal with psychological distress displayed by the Spanish adult population during the first State of Emergency and lockdown of the COVID-19 pandemic. This is a cross-sectional study that uses selective methodology complemented with an indirect observational methodology, with a nomothetic/punctual/unidimensional design. We collected 996 surveys from 19 out of the 22 autonomous regions in Spain. We focused the analysis on sociodemographic variables, cumulative incidence of the COVID-19 disease and psychological distress variables. We performed two different inferential analyses: Lag sequential analysis to define the participant coping patterns, and polar coordinate analysis to study the interrelationship of the focal behavior with conditioned behaviors. We found behavioral co-occurrent patterns of coping strategies with problem avoidance being found as the coping strategy most frequently engaged by participants. Interestingly, the problem avoidance strategy was not associated with lower anxious symptomatology. By contrast, emotion-focused strategies such as express emotions and social support were associated with higher anxious symptomatology. Our findings underscore the importance of furthering our understanding of coping as a way to aid psychological distress during global public health emergencies.

From randomized control trial to mixed methods: a practical framework for program evaluation based on methodological quality / Del ensayo controlado aleatorizado a los métodos mixtos: un marco práctico para la evaluación de programas basado en la calidad metodológica

The evidence used when making decisions about the design, implementation and evaluation in intervention programs should be methodologically sound. Depending on the context of the intervention, different methodologies may apply. Nonetheless, the intervention context is often unstable and, to adapt to changing circumstances, it sometimes becomes necessary to modify the original plan. The framework proposed herein draws on approaches that can be considered two extremes of a continuum (experimental/quasi-experimental designs and studies based on observational methodology). In unstable intervention context conditions, this enables decisions from a methodological quality approach regarding design, measurement, and analysis. Structural dimensions, i.e., units (participants, users), treatment (program activities), outcomes (results, including decisions about the instruments to use and data gathering), setting (implementation context) and time will be detailed as part of the practical framework. The present study aims to specify the degree of correspondence/complementarity between components in these structural dimensions of a program evaluation from a practical complementarity perspective based on methodological quality.(AU)

La evidencia utilizada al tomar decisiones sobre el diseño, implementación y evaluación en los programas de intervención debe ser metodológicamente sólida. Dependiendo del contexto de la intervención, se pueden aplicar diferentes metodologías. Sin embargo, el contexto de la intervención es a menudo inestable y, para adaptarse a las circunstancias cambiantes, en algunas ocasiones se hace necesario modificar el plan original. El marco propuesto en este documento se basa en enfoques que pueden considerarse dos extremos de un continuo (diseños experimentales / cuasiexperimentales y estudios basados ​​en metodología observacional). En condiciones de contexto de intervención inestable, esto permite tomar decisiones desde un enfoque de calidad metodológica en cuanto a diseño, medición y análisis. Las dimensiones estructurales, i.e., las unidades (participantes, usuarios), el tratamiento (actividades del programa), los resultados (incluidas las decisiones sobre los instrumentos a utilizar y la recopilación de datos), el entorno (contexto de implementación) y el tiempo se detallarán como parte del marco práctico. El presente estudio tiene como objetivo especificar el grado de correspondencia / complementariedad entre componentes en estas dimensiones estructurales de la evaluación de un programa desde una perspectiva de complementariedad práctica basada en la calidad metodológica.(AU)

Observational Analysis of Lateral Preference in Kumite Initiation: A Starting Point in the Longitudinal Programming of Formative Karate.

We used observational methodology to analyze lateral conditioning in the technical-tactical performance of high level 8-9-year-old karatekas, specifically in relation to the guard action that supports the technical action and the body segment with which it is performed. We designed an ad hoc observation instrument to analyze lateral preference in the technical-tactical actions that take place during the kumite. We relied on LINCE software for data registration, and we found good inter-observer reliability, calculated with Cohen's Kappa coefficient. Generalizability Theory supported the homogeneity of the behavior deployed by these combatants. Our results represent a starting point in the longitudinal programming of karate. By relating our results and those of other studies that have addressed lateral performance in formative karate in the kumite modality, we are able to draw a roadmap of a karateka's path towards the equilaterality that is inherent in an elite competitor: (a) the 8-9 year old karateka must overcome a conditioned lateral prevalence by adopting a forward non-dominant leg guard so as to then attack with the dominant body segment; (b) the eqilateral use of the right or left fist must occur later, between the 12-13 year age group and the senior category; and (c) there will then be less decisive lateral conditioning in the execution of offensive leg techniques.

Decision Making and Defensive Effectiveness of Ball Screen in Top-Level Basketball / Toma de decisiones y eficacia defensiva del bloqueo con balón en el baloncesto de alto nivel

The objective of this study is to analyze the effectiveness of the defensive actions of the pick and roll in basketball by ACB League teams throughout a full season (2010-11), contrasting the results obtained with the opinion of basketball experts on the decision-making process regarding this game action. The research uses direct observation (observational methodology) and indirect observation (in-depth interviews). An observational instrument is used to analyze the actions of pick and roll and this is recorded using the software Dartfish TeamPro v.4.5. For the in-depth interviews, an indirect observation instrument is built and validated. The significant association between different elements of the game and defensive efficiency is determined using Chi-square and a polar coordinate analysis. 8267 actions have been analyzed, of which 26.9% correspond to ball screens. Significant differences (p <.05) are detected in the distribution of the different types of defensive aid from the defender of the ball handler and the defender of the screener in relation to defensive effectiveness, the most widely used option being the chase and the show. The coaches express in their in-depth interviews why “pick and roll is such a widely used and effective action” (Scariolo).(AU)

Unraveling the Role of Shared Vision and Trust in Constructive Conflict Management of Family Firms. An Empirical Study From a Mixed Methods Approach.

Family firms are a unique setting to study constructive conflict management due to the influence of family ties of the owning family imprinting a sense of common purpose and shared destiny, and high levels of trust. We study the relationship between shared vision and trust that intervene in the adoption of constructive conflict management. To achieve our purpose, we carried out a systematic indirect observation using a mixed methods approach. We used the narratives of 17 semi-structured interviews, audio-recorded and transcribed, of family and non-family managers or directors from five Spanish family firms in the siblings' partnership stage, combined with documentary data obtained from different sources. Intra- and inter-observer reliability were confirmed. Results show a dynamic relationship between shared vision and specific components of trust (benevolence and ability) at different levels of conflict management. We also provide evidence of specific processes of concurrence-seeking and open-mindedness in family and ownership forums accounting for the relevance of family governance in these type of organizations. Family firms are a sum of several subsystems which exhibit a particular resources configuration. This study sheds light on constructive conflict management in family firms opening interesting avenues for further research and offering practical implications to managers, owners, and advisors.
