The aim of this study was to investigate the influence of the opponent’s quality on teams’ offensive efficacy of a Brazilian youth football team. The sample comprised 1.304 offensive sequences, from a U-17 team of the Paraná championship. The offensive sequences were divided according to the opponent’s quality (“high quality”, “intermediate quality” and “low quality”). Team’s offensive patterns were analysed through Lag Sequential Analysis. Thus, SoccerEye and SDIS-GSEQ software’s were used (p≤.05; z≥1.96). Offensive patterns with efficacy occurred mainly from directly ball recoveries (lag -5: z=3.13; lag -3: z=2.93), with progression through ball conduction (lag -4: z=2.85; lag -3: z=2.40; lag -2: z=2.64) and dribble (lag -5: 2.62; lag -2: z=2.51; lag -1: z=2.13; 1.97), playing between the lines against the opponent's last defenders’ line (lag -1: z=3.42; 2.72; 2.05; lag 0: z=4.65; 5.06; 3.15; 3.02) or performing rupture unmarks for the empty space between the goalkeeper and the last defensive line (lag -4: z=3.11; lag -1: z=3.48; lag 0: z=4.13; 7.80). Pressed numerical equality in game centre at defensive zones stimulated the possession loss (lag -2: z= 2.06; lag -1: z=3.01; lag 0: z=3.41; 1.96), demonstrating the importance of the numerical and spatial relationship for the effectiveness of actions. The opponent’s quality generated some oscillations in the patterns, nonetheless, in most patterns this team maintained similar behaviours. Considering this youth team, it is suggested that players be encouraged, regardless of the opponent's quality, to advance quickly from the defensive field; dominates the spaces between the lines; perform dribble, ball conduction and rupture unmarks towards the space between the goalkeeper and the opponent's last defensive line; in addition to pressing the opponent into their own field.  Resumen: El objetivo de este estudio fue investigar la influencia de la calidad del oponente en la eficacia ofensiva de un equipo de fútbol Juvenil de Brasil. Se analizaron 1.304 secuencias ofensivas, extraído de 17 partidos de este equipo en el Campeonato Sub-17 de Paraná, 2019. Las secuencias ofensivas se dividieron según la calidad del oponente ("alta calidad", "calidad intermedia" y "baja calidad"). Los patrones ofensivos del equipo se analizaron a través del análisis secuencial de retardos. Por lo tanto, se utilizaron los softwares SoccerEye y SDIS-GSEQ (p≤.05; z≥1.96). Los patrones ofensivos con eficacia ocurrieron principalmente a partir de recuperaciones directas de balón (lag -5: z=3.13; lag -3: z=2.93), con progresión a través de conducción (lag -4: z=2.85; lag -3: z=2.40; lag -2: z=2.64) y gambeta (lag -5: 2.62; lag -2: z=2.51; lag -1: z=2.13; 1.97), jugando entre líneas contra la última línea de defensores del oponente (lag -1: z=3.42; 2.72; 2.05; lag 0: z=4.65; 5.06; 3.15; 3.02) o realizando desmarques de ruptura para el espacio vacío entre el portero y la última línea de defensa (lag -4: z=3.11; lag -1: z=3.48; lag 0: z=4.13; 7.80). La igualdad numérica presionada en el centro de juego en las zonas defensivas estimuló la pérdida de posesión (lag -2: z= 2.06; lag -1: z=3.01; lag 0: z=3.41; 1.96), demostrando la importancia de la relación numérica y espacial para la efectividad de las acciones. La calidad del oponente generó algunas oscilaciones en los patrones, sin embargo, en la mayoría de los patrones este equipo mantuvo comportamientos similares. Teniendo en cuenta este equipo juvenil, se sugiere que se aliente a los jugadores, independientemente de la calidad del oponente, a avanzar rápidamente desde el campo defensivo; dominar los espacios entre líneas; realizar gambeta, conducción y desmarques de ruptura hacia el espacio entre el portero y la última línea defensiva del adversario; además de presionar al oponente en su propio campo.

The challenge of transforming an empty space into a gallery setting takes on the concept of place making. A place can be seen as space that has meaning when the setting considers space, surroundings, contents, the people and its activities. This research concentrates on investigating how visitors perceive the space by gauging their sense of place (sense of belonging towards a place). Galleries are currently facing changes in this technological era whereby multiple content and context, space and form, display modes, tools and devices are introduced in one single space. An observational study was done during the Foundation Studies Annual Exhibition held at Faculty of Creative Multimedia, Multimedia University. The exhibition was curated and managed by staff and students of Foundation Year showcasing an array of design works. Analogue and digital presentations of paintings, drawings, sculptures, photography and video works were displayed.. The outcome of this research will contribute towards a better design criteria of place making which affects individual behaviour, social values and attitudes. Characterizing types of visitor experience will improve the understanding of a better design criteria of place making, acceptance, understanding and satisfaction.

Level Performance

The process by which young talents develop to become top-class players once they reach the age of maximum performance is influenced by numerous factors. Among the exogenous factors, the family plays a central role. In the context of a research project carried out in cooperation with the Swiss Football Association SFV, 159 former members of the national youth football team were interviewed retrospectively, among other things concerning their family circumstances. The study is interested in understanding two issues: 1) It examines which family conditions – compared with average Swiss families – lead to success in adolescence (nomination for a national youth team). 2) Since success in adolescence by no means guarantees top-level performance at the age of maximum performance, the heterogeneity of the sample’s adult level of performance is used to compare players who later achieve greater success to the less successful players. It is found that these players come from families with many chil-dren and a strong affinity to sports. Those players who are particularly successful at the age of maximum performance also felt they received more support from their parents and siblings during childhood and adolescence than the players who went on to be less successful.

Cooperative Decision Making

This study investigates differences among four decision-making groups and describes the patterns of communication unique to two groups. In the first part of the investigation, four decision-making groups are given either competitive or cooperative inducements and are compared on two measures: competition and satisfaction. The two groups given the competitive inducement (Groups I and III) were found to have significantly higher competition and lower satisfaction than the groups given cooperative inducements (Groups II and IV). In the second part of the study a lag sequential analysis is conducted on the coded communicative sequences in the highest and lowest competition groups (I and II, respectively). This analysis yields patterns to decision-making unique to each sample group. Group I's communication is characterized by highly probable (above-chance) sequences of disagreement messages and few probable agreement messages. Group II's communication patterns consist of highly probable sequences of decision development and probable agreement/support messages throughout the group interaction.

Programming Process

The pair programming approach is used to overcome the difficulties of the programming process in education environments. In this study, the interaction sequences during the paired programming of preservice teachers was investigated. Lag sequential analysis were used to explore students’ behavioral patterns in pair programming. The participants of the study consist of 14 students, seven pairs enrolled in a Programming Languages course. The findings indicate that there are significant behavioral learning sequences. During the program development process, students hesitated to create an algorithm and to improve an existing one while proposing the next step. In addition, they constantly waited for approval. Collaborative behaviors such as giving and receiving feedback and helping other partners were less observed in females. In addition, significant sequential driver and navigator behaviors were presented. The findings of the study have important implications for instructors and designers when using a pair programming approach in teaching programming. In the future, programming instruction environments can be designed by considering the learner behaviors that are presented in this study.
