How can experts help governments think?: inaugural lecture

Britain’s exit from the European Exchange Rate Mechanism in 1992 and the Second Iraq War in 2003 are two infamous examples of disastrous policy, but governments blunder all the time – whatever party is in power. Infrastructure projects overrun. The aims and techniques of different departments clash. Scandals erupt among officials and politicians. Controversies stymie attempts at agreement and consensus. But why exactly do these failures happen? Are they more or less widespread than in the private sector? And can studying British governments’ decision-making across the twentieth century improve it in the future? In his May 2018 inaugural lecture, Professor O'Hara recommended a slow, deliberative, transparent, democratic and above all humble and sensitive approach in order to avoid another Black Wednesday or ruinous war – an approach in contrast to the populist tone of much recent debate.     

Behavior problems of children as perceived by teachers,mental health professionals,and children

The objective of this study was to examine current teacher and mental health professional ratings regarding the relative seriousness of 50 specific children's behavior problems and to compare the results to those found by Wickman (1928). Wickman's questionnaire and procedures were replicated to insure comparability. A second objective was to extend Wickman's work so that children's ratings of their own behavior problems may be ascertained. An increase in the similarity between teachers' and mental health professionals' judgements concerning the seriousness of specific children's behavior problems was found. These findings were attributable to a more pragmatic approach taken by mental health professionals. A very high agreement on the seriousness of specific behavior problem ratings was demonstrated by children and teachers. This similarity may be the result of proximity of effects.     

Self-regulation of timeout duration in the modification of disruptive classroom behavior

The effects of self-determination vs. teacher-determination of timeout duration on disruptive behavior were investigated in a group of 15 students in a special classroom who had learning disabilities and/or behavior problems. There were five phases to the study: In a repeated measures design each subject received timeout for 5 minutes, no timeout, 5 minutes timeout, selfdetermined timeout duration, and student = teacher-determined timeout duration. The overall effect of timeout was to reduce significantly the rate of disruptive behavior. The effects of various timeout conditions did not differ, indicating self-management of timeout duration was just as effective as when the teacher set the timeout duration.     

Ending the perpetuation of sex-role stereotypes in our schools: A possible consequence of psychological androgyny

Research has shown that both historically and currently there has been sex-differentiated staffing in American public schools, with a disproportionate number of female teachers at the elementary level. Concern long has been expressed regarding the impact this might have on the sex-role development of American children and the perpetuation of stereotypic staffing patterns. This article supports the hypothesis that psychologically androgynous individuals might be more likely than masculine or feminine individuals to base teaching level choice upon individual preference without regard for its stereotype as more appropriate for one sex than the other. Data collected from preservice teachers at Washington State University support this hypothesis. It was found that while feminine females were more apt to choose the elementary teaching level, masculine males were more apt to choose secondary teaching. In comparison, androgynous preservice teachers of both sexes were as likely to choose the elementary as secondary teaching level.     

Experiences of Danish Business Expatriates in Russia: Power Distance in Organizational Communication

Rapid globalization of business processes stimulates many companies to dispatch their employees – business expatriates – on overseas assignments. Russia differs markedly from many other cultures in terms of specific communication norms and rules. Understanding such differences in organizational life is crucial for the success of business expatriates working there. This study employs in-depth interviews with eight Danish business expatriates who worked in Russia and examines the differences between the Danes and the Russians in terms of communication characteristics related to Hofstede’s cultural dimension power distance. This work enhances scholars’ empirical knowledge of power distance, which has rarely been investigated qualitatively.     

Lack of Relationship Between Functional and Perceived Quality of Life Outcomes Following Pulmonary Rehabilitation

Individuals with chronic obstructive pulmonary disease (COPD) have been shown to benefit from participation in pulmonary rehabilitation (PR) programs that include exercise training and education. Purpose: To examine the relationship between improvements in 6 minute walk distance and perceived quality of life in individuals with COPD following completion of a PR program. Methods: The records of 139 individuals completing a PR program (3 times a week for 8 weeks) were retrospectively examined. Prior to entry and upon completion of the program each individual completed a 6 minute walk test (6MWT), the SF-36 Health survey, and the UCSD Shortness of Breath Questionnaire (SOB). SF-36 results were analyzed according to 8 subscales [Physical Functioning (PF), Role Physical (RF), Bodily Pain (BP), General Health (GH), Vitality (V), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH)]. Results: PR resulted in significant improvements in 6MWTdistance (Pre = 845 ± 37 ft, Post = 1127 ± 32 ft, p < 0.001), PF (p < 0.001), RF (p = 0.001), Vitality (p = 0.002), SF (p < 0.001), RE (p = 0.037), MH (p < 0.001) and SOB (Pre = 53 ± 2, Post = 47 ± 2, p < 0.001). The change in 6MWT distance was not related to changes in PF (r = 0.17), RF (r = 0.03), GH (r = 0.03), Vitality (r = −0.001), SF (r = 0.01), RE (r = 0.06), MH (r = −0.04) or SOB (r = 0.12). The magnitude of improvement in 6MWT distance (68%) was much greater than that observed in PF (15%), RF (16%), GH (6%), VT (18%), SF (20%), RE (14%), MH (14%), or SOB (8%). Conclusions: PR has a positive impact on 6 minute walk distance and perceived quality of life in individuals with COPD; however, changes in 6 minute walk distance appear to have no relationship to changes in perceived quality of life.     

Biomechanics of aggressive inline skating: landing and balancing on a grind rail

Currently, only epidemiological injury data have been reported for the new extreme sport of aggressive inline skating, or trick skating. No studies have examined the biomechanics of this sport, which involves repetitive jumping and landing from railings, ramps, and ledges, often over 1 m in height. We present results of a pilot study that examined the effect of skater experience and lower extremity biomechanics on energy absorption ability, and observed balance strategies used during two basic tricks. In these tricks, the skater jumps onto an elevated rail and maintains balance while standing in a single position (stall) or sliding along the rail (grind). Lower extremity joint kinematics, impact force characteristics, and general movement behaviours were examined during landing and balance phases. Ten male skaters performed ten stalls and ten frontside grinds on an instrumented grind rail, capable of measuring vertical force. Vertical impact force was found to decrease with increasing skater experience in stalls (r = -0.84, P = 0.002) and grinds (r = -0.84, P = 0.009). This might imply that less-experienced skaters are (subconsciously) more concerned about maintaining balance than refining technique to minimize impact force. Similar to drop landing experiments, peak impact force decreased with increasing knee flexion during stalls (r = -0.65, P = 0.04). During stalls, skaters demonstrated classic balance maintenance strategies (ankle, hip, or multi-joint) depending on trick length. During grinds, skater centre of mass never passed over the rail base of support, suggesting the use of momentum produced from obliquely approaching the rail.     

Geographic clustering of economic activity: The case of prominent western visual artists

This article compiles original data relating to artists’ place of birth and work migration patterns using various art history dictionaries. The broad historic pattern, from the 13th to the 20th century, of the birth locations of prominent artists is examined, followed by a detailed study of the work migration patterns of prominent artists in two important situations, namely Renaissance Italy and France in part of the 19th century. The evidence indicates a marked clustering of activity of prominent artists, both arising from birth location and migration patterns. Some possible explanations for the observed patterns are briefly outlined.
