Personality of elite male and female chess players and its relation to chess skill

Whereas a lot of studies examine cognitive processes in chess players, personality profiles of elite chess players are still not described well. The aim of this study was to examine personality of strong chess experts and its influence on chess skill. We tested elite male and female chess players with Freiburg Personality Inventory Revised (FPI-R), which also provides population norms for males and females. Elite male players' personality profile did not significantly differ from the population norms. Female players were more satisfied with life, had less physical complaints and higher achievement motivation in comparison with female population norms. Personality was also related with chess skill but showed different patterns in males and females. Stronger male players were more introverted, while we found the opposite pattern in female players. These results indicate that personality plays an important role in the highest level of complex intellectual activities.     

Prediction of self-reported knowledge with over-claiming, fluid and crystallized intelligence and typical intellectual engagement

We investigated the usefulness of the Over-Claiming Questionnaire (OCQ) as a measure of cognitive abilities. In OCQs respondents are asked to rate their familiarity with items of academic or everyday knowledge (Paulhus, Harms, Bruce, & Lysy, 2003). Some items exist in reality (reals), and others do not (foils). We developed four OCQs, each consisting of 40 reals and 8 foils from the domains of Science, Humanities and Civics. The OCQs were administered in a longitudinal rotation design to 112 participants who attended the 9th school grade at the beginning of the study. In latent variable regression analyses 53% of variation in the reals could be explained by fluid and crystallized intelligence and over-claiming as indicated by responses to foils. Further variation in responses to reals and foils was explained by intellectual engagement. Our results show that self-reported knowledge, although positively related to measures of ability, to a large extent reflects over-claiming.     

Influence of casein phosphopeptide-amorphous calcium phosphate application,smear layer removal,and storage time on resin-dentin bonding

The aim of this study is to evaluate the influence of Tooth Mousse (TM) application, smear layer removal, and storage time on resin-dentin microtensile bond strength (μTBS). Dentin specimens were divided into two groups: (1) smear layer covered; (2) smear layer removed using 15% EDTA for 90 s. In each group, half the specimens were treated once with TM for 60 min. After bonding procedures using a two-step self-etching adhesive (Clearfil SE Bond (CSE); Kuraray Medical, Tokyo, Japan), an all-in-one adhesive (G-Bond (GB); GC Corp, Tokyo, Japan), and a total-etch adhesive (Adper Single Bond 2 (SB); 3M ESPE, St. Paul, MN, USA), the specimens were stored for 3 d or 6 months in deionized water at 37 °C, and μTBS was tested and analyzed. With the exception of SB (no TM application) and GB, the μTBS was significantly increased for CSE and SB using EDTA pre-conditioning and 3 d of storage (P≤0.001). Bond strength of GB decreased significantly when using EDTA (3 d storage, P<0.05). TM application only increased the μTBS of GB (no EDTA) and SB (with EDTA) after 3 d (P≤0.02). Comparing the adhesives after 3 d of storage, CSE exhibited the greatest μTBS values followed by GB and SB (P≤0.02). The factors of adhesive, EDTA, and TM did not show any significant impact on μTBS when specimens were stored for 6 months (P>0.05). The additional application of TM and EDTA for cavity preparation seems only to have a short-term effect, and no influence on μTBS of dentin bonds after a period of 6 months.     

‘Active Citizens’: the case of school governors

ABSTRACT

This article reviews current and historical debates about active, participant citizens and related conceptions of citizenship. In particular it focusses on the prospects for the participation of citizens in the administration of public bodies. It discusses critically the notion of participative citizenship and active citizenship as articulated by Douglas Hurd (when Home Secretary) and also the version contained in the report of the Speaker's Commission on Citizenship. The article then draws upon research conducted for the Volunteer Centre, by the National Foundation for Educational Research and that by Brehony and Deem which is funded by an Economic and Social Research Council Grant (R000 23 1799), on voluntary activity and school governors, respectively. The applicability of the concept of active citizenship to the oversight of schools by school governing bodies is then considered alongside recent work in the United States. The article then considers the constraints upon active citizenship which prevent many governors from participating as much as the role demands and it ends with a reference to the tension between those who see governing bodies as an arena for democratic accountability and the active participation of citizens and those who view them principally as a means by which the local state is weakened and its functions increasingly transferred to the voluntary sector.     

Troubling the concept of the ‘academic profession’ in 21st Century higher education

Concern has been expressed about the vulnerability of the ‘academic profession’ as a consequence of threats from productivism, managerialism and the like (Beck and Young, Br J Sociol Educ 26(2):183–197, 2005). I question the apparent self-understanding of academe as a profession. Referring to thinking from higher education (Barnett, High Educ 40:409–422, 2000a; Educ Phil Theor 32(3):319–326, 2000b; Realizing the University in an age of supercomplexity, 2000c; Stud High Educ 25(3):255–265, 2000d; Lond Rev Educ 2(1):61–73, 2004a; Piper, Are professors professional? The organisation of University examinations, 1994; Taylor 1999), and from the sociology of the professions (in particular Evetts, Int J Sociol Soc Policy 23(4/5):22–35, 2003a; Int Sociol 18(2):395–415 2003b; Curr Sociol 54(1):133–143 2006a; Curr Sociol 54(4):515–531, 2006b), I propose that significant shifts in self-understanding and practice are needed for academe to claim a social role as a ‘profession’.     

Change in Fluid and Crystallized Intelligence and Student Achievement: The Role of Intellectual Engagement

Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2‐year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but not changes therein, and was not associated with fluid ability. Furthermore, IE predicted change in school grades in language but not in mathematics grades or in standardized tests. These findings suggest that IE is not a major predictor of knowledge acquisition in adolescence, where degree of self‐determination in intellectual behaviors may be relatively limited. Open questions for future research are addressed, including reciprocal longitudinal associations between IE and academic and cognitive development.
