When off-line seeks information online: The effect of modality switching and time on attributional confidence and social attraction

This study’s goal was to learn how adding the extractive information-seeking behavior of Facebook profile viewing following face-to-face information-seeking behavior in initial interactions affected attributional confidence (AC) and social attraction (SA). Additionally, the present study was a quasi-replication of research exploring how changes in time spent on information seeking impacted AC and SA testing two uncertainty reduction theory axioms. Two modalities, face-to-face (FtF) only versus FtF and profile viewing, across three time conditions of 4, 6, and 8 minutes yielded six experimental conditions. AC for the two modalities were similar when time was held constant. Comparing the two modalities for 8 minutes resulted in higher social attraction for the FtF-only condition. Also, the data report a significant interaction with modality and time. Time impacts AC and SA even with relatively small changes.     

Geschlechterrollenorientierungen und ihre Beziehungen zu Maßen der Ich-Stärke bei Jugendlichen aus Ost-und Westberlin

Zusammenfassung In einer Stichprobe von 2630 Jugendlichen achter Klassen aus Gymnasien, Real-, Gesamt-und Hauptschulen in Ost-und Westberlin wurde im Jahr 2001 die Akzeptanz von Geschlechterrollenorientierungen (traditionell vs. partnerschaftlich) erfasst und ihr Zusammenhang mit Ma?en der Ich-St?rke (positives Bild von sich selbst, psychische Stabilit?t, produktiver Umgang mit Erfolg und Misserfolg) untersucht. Dem partnerschaftlichen Konzept wurde in h?herem Ma?e zugestimmt als dem traditionellen. Dabei ergaben sich Geschlechts-, Ost/West-sowie Schulartunterschiede in der partnerschaftlichen sowie traditionellen Orientierung. Weibliche Jugendliche waren weniger traditionell eingestellt als m?nnliche. Ostberliner Schüler/innen waren weniger traditionell orientiert als Westberliner und Gymnasiast/inn/en hatten eine niedrigere traditionelle Orientierung als Gesamt-, Real-und Hauptschüler/innen. Je h?her der Bildungsstand (gemessen an der Schulform und dem Bildungsniveau der Mutter), desto h?her war die Akzeptanz der Gleichberechtigung der Geschlechter. Die Jugendlichen wurden nach dem Grad ihrer traditionellen Orientierung in drei Cluster eingeteilt und hinsichtlich der Auspr?gung von Ma?en der Ich-St?rke miteinander verglichen. Dabei zeigte sich, dass Jugendliche mit hoher traditioneller Orientierung ein niedrigeres Selbstwertgefühl, sowie eine h?here Leistungsangst, mehr Furcht vor Misserfolg und in h?herem Ma?e selbstwertmindernde Attributionen ?u?erten als Jugendliche mittlerer und niedriger traditioneller Orientierung. Jugendliche, die in h?herem Ausma? über die pers?nliche Ressource der Ich-St?rke verfügen, traten h?ufiger für die Gleichberechtigung der Geschlechter ein. Summary Sex-role-orientation and its Relationship to Egostrength in Adolescents from East and West Berlin A sample of 2630 adolescents from grade 8 attending different types of secondary school in East and West Berlin was assessed in 2001. The aim was twofold: to ascertain their acceptance of gender-role orientation (i.e. traditional norms vs. equality in gender relations) and to link it to degrees of ego-strength (high self-concept, psychological stability, ability to deal with success or failure in a constructive manner). The concept of equality in gender relations was found to be more prevalent among females, pupils in East Berlin and those pupils attending grammar schools. The higher the education level of the pupils (measured according to the school attended and the education level of their mothers), the greater the acceptance of gender equality. The adolescents were classified in three clusters according to the degree of traditional orientation and then compared. Results showed that adolescents with a high traditional orientation displayed lower self-concept, a higher level of test anxiety, greater fear of failure and higher attribution of failure to lack of ability than those adolescents with moderate and low traditional orientation. Those displaying a greater range of characteristics related to ego-strength supported gender equality more frequently.      

Lead soaps in paintings: Friends or foes?

The origin(s) and role(s) of metal soaps in paints are a worldwide concern today. These hybrid compounds, containing both fatty acid chains and metals associated with a carboxylate function, are increasingly identified in paints. As reviewed in the first part of this work, the presence of metal soaps in paints is differently interpreted in scientific publications: metal soaps are sometimes considered to play a positive role as anchor points, during paint drying processes; they can also be considered as responsible for many degradation processes (protrusions, efflorescences, darkening, etc.). Their origins are also interpreted in various ways. In some paintings (in particular from the twentieth century), they have sometimes introduced on purpose, as additives, to modify the physical properties of the painting materials. In older paintings, metal soaps are usually thought to result from an uncontrolled reaction of oil with lead-based pigments, in particular lead white, red lead, and lead tin yellow. In the second part of this work, the review of historical recipes of lead-based paint shows an important number of recipes based on controlled mixing of oil with lead driers. In the third part, the experimental reproduction of such traditional recipes using walnut oil and litharge (PbO) shows that lead soaps can be formed, both in about one hour at ～100°C, or in about one month at room temperature. It shows as well that after a few years, litharge is no longer detected in the paint medium, while different lead carbonates are. Finally, the micro-infrared spectroscopy and micro-X-ray diffraction re-analysis of protrusions from a nine-year model painting shows together with lead soaps, the presence of Pb₅(CO₃)₃(OH)₂O (‘synthetic plumbonacrite’), an unusual phase recently observed in a protrusion from a painting by Vincent Van Gogh. This work highlights (i) the multiple origins and roles of metal soaps in paints and (ii) the importance of combining the analysis of fragments from historical paintings with the analysis and reproduction of historical recipes. In particular, we show that the components detected today in historical paintings may severely differ from those originally used or prepared by the painter, complicating the assessment of the painter's intentions. More than the presence of metal soaps, the key questions to be tackled should be about their origins and (re)mobilization.     

FACILITATING THE DEVELOPMENT OF TALENTS

World class pioneering achievements are a nation's most valuable asset. They arise from the efforts of talents‐people of extraordinary ability. The vital task of fostering the emergence of such talents requires a concentrated effort covering the entire lifespan. Significant factors are parents, contemporaries and teachers as well as media, the societal atmosphere and contact with great social and scientific issues. These must act together to produce talents with not only the ability but also the dedication to achieve.

     

International collaboration in science and the formation of a core group

International collaboration as measured by co-authorship relations on refereed papers grew linearly from 1990 to 2005 in terms of the number of papers, but exponentially in terms of the number of international addresses. This confirms Persson et al.'s [Persson, O., Glänzel, W., & Danell, R. (2004). Inflationary bibliometrics values: The role of scientific collaboration and the need for relative indicators in evaluative studies. Scientometrics, 60(3), 421–432] hypothesis of an inflation in international collaboration. Patterns in international collaboration in science can be considered as network effects, since there is no political institution mediating relationships at that level except for the initiatives of the European Commission. Science at the international level shares features with other complex adaptive systems whose order arises from the interactions of hundreds of agents pursuing self-interested strategies. During the period 2000–2005, the network of global collaborations appears to have reinforced the formation of a core group of fourteen most cooperative countries. This core group can be expected to use knowledge from the global network with great efficiency, since these countries have strong national systems. Countries at the periphery may be disadvantaged by the increased strength of the core.     

Kinderbetreuungspolitik in Deutschland

Childcare Policy in Germany: Scope for Demand side Subsidies German day care policy is a perfect example of the provision of social services in a neocorporatist fashion. Day care centers are primarily financed from the local community budget. From this budget, the community runs public day care centers or subsidies Non-Profit Organizations which provide day care for children. In established negotiations on the community level, representatives of the NPOs and the public providers decide on the supply of slots in day care centers. In this paper, we argue that this particular mode of financing and monitoring children’s day care has contributed to a rather conservative childcare policy in Germany. Being dependent on the very restricted local budget, communities are confined to conduct a daycare policy, which solely offers a minimum provision of public day care. We suggest a radical reform of German day care policy. Instead of the subsiding public institutions and NPOs, we suggest to support the use of day care by demand side subsides. In this context, we describe some features of a child care voucher model in Germany.     

Genome-Wide Polygenic Scores Predict Reading Performance Throughout the School Years

It is now possible to create individual-specific genetic scores, called genome-wide polygenic scores (GPS). We used a GPS for years of education (EduYears) to predict reading performance assessed at UK National Curriculum Key Stages 1 (age 7), 2 (age 12) and 3 (age 14) and on reading tests administered at ages 7 and 12 in a UK sample of 5,825 unrelated individuals. EduYears GPS accounts for up to 5% of the variance in reading performance at age 14. GPS predictions remained significant after accounting for general cognitive ability and family socioeconomic status. Reading performance of children in the lowest and highest 12.5% of the EduYears GPS distribution differed by a mean growth in reading ability of approximately two school years. It seems certain that polygenic scores will be used to predict strengths and weaknesses in education.
