Social play as joint action: A framework to study the evolution of shared intentionality as an interactional achievement

Social play has a complex, cooperative nature that requires substantial coordination. This has led researchers to use social games to study cognitive abilities like shared intentionality, the skill and motivation to share goals and intentions with others during joint action. We expand this proposal by considering play as a joint action and examining how shared intentionality is achieved during human joint action. We describe how humans get into, conduct, and get out of joint actions together in an orderly way, thereby constructing the state of “togetherness” characteristic of shared intentionality. These processes play out as three main phases, the opening (where participants are ratified and joint commitments are established), the main body (where progress, ongoing commitments, and possible role reversals are coordinated), and the closing (where the intention to terminate the action is coordinated and where participants take leave of each other). We use this process in humans as a framework for examining how various animal species get into, maintain, and get out of play bouts. This comparative approach constitutes an alternative measure of those species’ possession of shared intentionality. Using this framework, we review the play literature on human children and different social species of mammals and birds in search of behavioral markers of shared intentionality in the coordination of play bouts. We discuss how our approach could shed light on the evolution of the special human motivation to cooperate and share psychological states with others.     

Job tasks and the participation of low-skilled employees in employer-provided continuing training in Germany

This study analyses the participation of low-skilled employees in employer-provided training and examines the mechanisms that encourage the training participation of low-skilled employees. Building on theoretical considerations of human capital theory and the task-based approach, we seek to show that job tasks play an important role in explaining different participation levels of low-skilled employees in employer-provided continuing training. The empirical analyses are based on data from the new survey on establishments in Germany. To test the influence of job tasks on participation of low-skilled employees in employer-provided training, we run multivariate regression models that control for other explanatory variables. The results of our analysis confirm that job tasks are relevant to changes in the participation rates of low-skilled employees, which leads to the conclusion that differences between job tasks affect employers’ willingness to invest in training for their low-skilled staff.     

Der Einfluss der kommunalen Steuerung auf die Weiterbildungsbeteiligung – Ein Mehrebenen Modell mit Daten des Mikrozensus in Deutschland

Few analyses of participation in continuing education take into account management at the local or regional level. This is surprising, since continuing education is expected to react not only to global changes in employment structures, but also to local changes in demographic structures, qualification levels or migration flows. Responding to this problematic situation with individualized and diverse choices is especially challenging considering that, in recent years, local community administrations have also been given the responsibility of managing continuing education programs. Questions arise regarding the extent to which local communities actually address the needs of specific (non-)participant groups and the role community management of continuing education plays. These questions are investigated using a multi-level model which looks at the impact of local community administrative practices on participation in continuing education by members of certain social groups. We find differences between districts in the continuing education participation of older persons as well as less qualified males.     

Sportunterricht

Physical education is linked with hopes of health improvement. Especially for children and adolescents who are inactive in leisure, physical education (P.E.) is of great importance. The purpose of this paper is to answer the question whether the health status of inactive children and adolescents differs depending on the number of P.E. lessons attended. This question was analyzed with a sub-sample of the KiGGS (children and adolescents health survey) and MoMo (motoric module) studies of inactive subjects (n=310; age 7–17 years) who were classified into two groups depending on the number of P.E. lessons attended (up to 2 lessons/week; more than 2 lessons/week). Health status was assessed using questionnaires, motor performance tests and laboratory findings. Analyses of variance showed no significant differences between the two groups concerning health parameters.     

Entwurf und Implementierung eines SQL-normkonformen Datenbankkatalogs für ein relationales Datenbankmanagementsystem

Zusammenfassung.   Bei relationalen Datenbanksystemen haben sich de-jure-Normen für SQL stetig weiterentwickelt; mit diesen Normen wird es einfacher, portable Datenbankanwendungen zu entwickeln. Die SQL-Norm ruht auf zwei S?ulen, zum einen auf der Datenbanksprache SQL, zum anderen auf einer Vorgabe eines Datenbankkatalogs, welcher die gespeicherten Daten beschreiben soll. Im vorliegenden Beitrag wird derjenige Teilbereich des Datenbankkatalogs der aktuellen SQL99-Norm dargestellt, der bereits in der SQL92-Norm (ISO/IEC 9075:1992 bzw. DIN 66315) definiert ist und die klassischen (nicht objektrelationalen) Elemente einer relationalen Datenbank beschreibt. In dieser Darstellung nimmt der zweischichtige Spezifikationsansatz (Informationsschema, Definitionsschema) einigen Raum ein; mit seiner Hilfe weist SQL einen eleganten Weg, auf dem existierende Datenbanksysteme normkonforme Datenbankkataloge bereitstellen k?nnen. Anhand des Datenbankmanagementsystems DB2 wird anschlie?end untersucht, wie ein normkonformer Datenbankkatalog (das sogenannte Informationsschema) „oberhalb” des verfügbaren DB2-Katalogs realisiert werden kann, d. h. wie die vom Informationsschema geforderten Sichten auf DB2-Katalogtabellen abgebildet werden k?nnen. Auf generelle Schwierigkeiten und M?glichkeiten einer solchen Abbildung (ein- oder zweistufig) wird ebenso eingegangen wie auf Probleme, die sich speziell bei DB2 ergeben. In einer prototypischen Realisierung konnte das Informationsschema bis auf wenige Einschr?nkungen komplett umgesetzt werden. Damit wurde die Machbarkeit normkonformer Kataloge nachgewiesen. In heute verfügbaren DBMS-Produkten sind Datenbankkataloge in dieser konsequent normkonformen Gestalt leider immer noch nicht anzutreffen. Eingegangen am 5. M?rz 1999 / Angenommen am 1.

Youth multi-sport events in Austria: tourism strategy or just a coincidence?

Impact and legacy research of touristic issues has become more popular with the appearance of manifold approaches to examining tourism. In recent years, the region of Western Austria has successfully staged multi-sport youth events, with two being staged in Innsbruck, Tyrol (YOG 2012; ICG 2016) and one in the region of Montafon, Vorarlberg (EYOF, 2015). This leads to the assumption that the high frequency of youth sports events in these regions necessitates and therefore also follows a set hosting policy or at least a strategic approach to event bidding and staging. To examine these assumptions, a mix of desk research and qualitative interviews was chosen, encompassing bidding files, final reports, official tourism statistics, press releases from tourism boards, political working papers, internal documents and interviews with organising committee members, event experts and political representatives. Staging youth sports events is found to have left legacies in Western Austria such as generating immediate overnight stays in the low season and creating a positive image for the host regions, depending on the frequency with which events are staged and affirming the purpose of using events to boost tourism. The host areas lacked a written (youth sport) strategy and unexpectedly, the existing strategies do not include the youth sports events. However, it can be assumed in the case of Innsbruck that a hidden event strategy exists. In conclusion, the study reveals the importance of sharing events and their benefits among the various local stakeholders, thus branding the region as a host city.     

Politicians’ perspective on the community-related impacts of major sports events – a case study for Innsbruck-Tyrol

While scholarly attention with respect to the social impacts of sports events has increased in recent years, there is still little research discussing the wide-ranging community-related impacts stemming particularly from major sports events. Local political leaders, as (elected) representatives of the community, are important stakeholders within this context and face the challenge of balancing diverse interests in the implementation of major sports events. The purpose of this study is to assess the importance politicians attribute to event impacts that create sustainable outcomes for residents living in a host city. Based on a content analysis, a list of general event impacts (outputs and legacies) produced by major sports events was created and subsequently discussed with scholars and experts in the field to classify the criteria as community relevant or not. A final number of 56 criteria (34 of which are considered community relevant) was then used in the assessment of the politicians’ (representing either the State of Tyrol or the City of Innsbruck) attitude towards these impacts. The findings of the study indicate that, though aware of community interests, politicians nevertheless prioritize economic and touristic benefits for the host city/region such as place marketing. Moreover, politicians seem to have a better understanding of tangible impacts (e.g. infrastructure), underestimating the important intangible impacts (e.g. voluntariness) closely related to community issues. Thus, the research in hand outlines the need to sensitize governments to community interests when planning and implementing major sports events.

Structuring and sequencing of complex text-picture combinations

This study investigates the structuring and sequencing of a special type of verbal-pictorial learning material, namely “explanative illustrations” (Mayer, 1993). In such illustrations verbal and pictorial parts form an integrated whole with text embedded in the pictures and vice versa. Due to their complexity such instructing illustrations impose high demands on information processing. From the viewpoint of instruction one may ask how the reception of such explanative illustrations may be supported by an appropriate structure and sequence of the content. In two empirical investigations three types of content structures and sequences were compared to each other: (1) a top-down sequence (based on assumptions of the “Elaboration Theory”, Reigeluth, 1987b) from the whole to details which shows how details are embedded within the larger context), (2) a bottom-up sequence from details to the whole, (3) the presentation as a whole (as in print).
