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).     

Stichwort: Internationalisierungsprozesse und Elitebildung

Processes of internationalisation are not a novel phenomenon: they have been present since the beginning of human history and have been the subject of theories and analyses since the early days of social-science research. This article highlights (1.) the social pre-conditions of historical and current processes of trans-regional communication and exchange, and argues that (2.) these conditions were not superseded but reinforced by the rise of nation states and their international relations. They are based on processes of cultural standardisation, differentiation and competition, which also fuel and transform elite formation and elite competition. (3.) With the emergence of international organisations in the wake of World War II, historical processes of international standardisation and competition were extended to national education systems. (4.) National education systems are currently witnessing a transformation which originates partly from the competition between national and international elites, and partly from new dynamics in international migration.     

Cultural Differences in Maternal Beliefs and Behaviors: A Study of Middle-Class Anglo and Puerto Rican Mother-Infant Pairs in Four Everyday Situations

This study examines cultural patterning in situational variability in mother-infant interactions among middle-class Anglo and Puerto Rican mothers and their 12 to 15-month-old firstborn children. Forty mothers were interviewed regarding their long-term socialization goals and childrearing strategies, and videotaped interacting with their infants in four everyday settings: feeding, social play, teaching, and free play. Results suggest that: (1) Anglo mothers place greater emphasis on socialization goals and childrearing strategies consonant with a more individualistic orientation, whereas Puerto Rican mothers place greater focus on goals and strategies consistent with a more sociocentric orientation; (2) coherence was found between mothers' childrearing beliefs and practices, with Puerto Rican mothers more likely to directly structure their infants' behaviors; and (3) situational variability arose in mother-infant interactions, but this variability showed a cultural patterning consistent with mothers' long-term socialization goals and childrearing beliefs.     

International Trade in Art

This paper investigates the extent to which trade theory is applicable for explaining trade in art. Reproducible art is distinguished from unique art and it is argued that the trade in reproducible art is, at least in principle, governed by the same economic laws as trade in other differentiated products. However, trade theory needs to be amended in order to account for the addictive character of art consumption: culture specific consumption capital is built up with art consumption. Moreover, trade in unique art is mainly trade between consumers, a phenomenon largely ignored by standard trade theory. Empirical evidence on trade in art is presented and a gravity model of international trade in works of art is estimated. Finally, the paper discusses open questions for future research.     

Providing Consultation About Boundary Dilemmas to Paraprofessional Staff Working With People With Severe Psychiatric Disabilities

ABSTRACT

Social justice has been suggested as a possible global moral framework for school psychology. It is, however, culturally understood and research suggests that the engagement with “social justice” in school psychology has been largely limited to a U.S. context. This project sought to extend international understandings and practices of social justice in school psychology. A thematic analysis of nine interviews with educational psychologists based in England was conducted. Social justice was defined as complex, and participants suggested it is important to educational psychology practice in part because of current cuts to public services and educational reforms. Findings also indicated a role for social justice consultation, building relationships, and engaging with broader macrolevel work to enact a social justice agenda. We discuss these findings in relation to previous literature, concluding that our research begins to document the seeds of a broader social justice agenda in school psychology.     

Systematic lossy error protection based on H.264/AVC redundant slices and flexible macroblock ordering

INTRODUCTION In typical video transmission systems, a video signal is compressed, and the resulting bit stream is transmitted over an error-prone channel. The errors may consist of symbol errors caused by fading, as observed for wireless channels, or packet erasures caused by congestion, as observed in the Internet. If a received video packet contains errors, then the portion of the video signal contained in the packet is lost and must be concealed. Error concealment schemes alone cannot …

Interactional conditions of syntax acquisition: A review

This paper reviews how and why children's acquistion of syntactic structures is influenced by verbal communication with adults. It argues that those interactions involve cooperative problem-solving and can be interpreted within interactionist theory. It surveys several ways in which adults model a child's syntactic structure to convey the child's intended meaning. These are: expansion; extension; modelling without prior child utterance; and modelling after metalinguistic interruption of the conversation.University of BielefeldState Institute for Early Education
