Developing a framework for responsible innovation

The governance of emerging science and innovation is a major challenge for contemporary democracies. In this paper we present a framework for understanding and supporting efforts aimed at ‘responsible innovation’. The framework was developed in part through work with one of the first major research projects in the controversial area of geoengineering, funded by the UK Research Councils. We describe this case study, and how this became a location to articulate and explore four integrated dimensions of responsible innovation: anticipation, reflexivity, inclusion and responsiveness. Although the framework for responsible innovation was designed for use by the UK Research Councils and the scientific communities they support, we argue that it has more general application and relevance.     

Effects of Aerobic Exercise on Overweight Children's Cognitive Functioning

The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index ? 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control condition. Exercise sessions met 5 days/week for 15 weeks. The Cognitive Assessment System (CAS), a standardized test of cognitive processes, was administered individually before and following intervention. Analysis of covariance on posttest scores revealed effects on executive function. Group differences emerged for the CAS Planning scale (p = .03). Planning scores for the high-dose group were significantly greater than those of the control group. Exercise may prove to be a simple, yet important, method of enhancing aspects of children's mental functioning that are central to cognitive and social development.     

The 1983 C.H. McCloy Research Lecture Appetite and Body Composition Consequent to Physical Activity

Abstract

Body composition has become a major field of interest for many exercise and sport scientists as well as clinicians who specialize in the prevention of and rehabilitation from hypokinetic diseases. This review article discusses the state of the art within selected areas of body composition, including the following: exercise in appetite regulation, the use of body density to estimate relative body fat in selected populations, the use of anthropometric equations to estimate body composition, and alterations in body composition with exercise training. It was concluded that acute bouts of exercise may have short term anorexigenic effects, but that alterations in appetite with extended periods of training are less clearly defined. Exercise training does result in modest decreases in total and fat weight and in relative body fat, and small increases in lean body weight. However, these alterations are not substantial. Finally, major research efforts are needed to improve methodology in body composition assessment.     

Assessment of decision-making performance and in-game physical exertion of Australian football umpires

Abstract

The aim of this study is to investigate the effects of in-game physical exertion on decision-making performance of Australian football umpires. Fifteen Australian football umpires (M_age = 36, s = 13.5 years; M_{games umpired} = 235.2, s = 151.3) volunteered to participate in the study. During five competitive Australian football pre-season games, measures of in-game physical exertion (blood lactate levels, global positioning system [GPS]) and decision-making performance (video-based test) were obtained. There were no significant correlations between physical exertion in a particular quarter and decision-making performance in either the same quarter or any other quarter. Video-based decision-making performance was effected by time in game χ²(3) = 24.24, P = 0.001, with Quarter 4 performance significantly better than both Quarter 2 and Quarter 3. In-game physical exertion (blood lactate) significantly decreased over the course of the game χ²(3) = 11.58, P = 0.009. Results indicate no definable link between in-game physical exertion and decision-making performance. It is, however, presumed that decision-making performance may be affected by the time or context of the game. Future research is warranted to explore the relationship between physical exertion and decision-making performance to potentially inform Australian football umpire training programmes that replicate in-game physical and decision-making demands.     

Effects of Altered Stride Lengths on Ratings of Perceived Exertion during Running

Abstract

The purpose of this study was to determine the effects of stride length variations on ratings of perceived exertion (RPEs) in experienced recreational runners. Twenty-eight male college students were randomly divided into equal-sized treatment and control groups. The treatment group performed five 15 min altered stride length runs, each separated by a minimum of 48 hr. The five trials involved running with a freely chosen stride length (FCSL) and a FCSL altered by +14%, +7%, ?14%, and ?7%. The control group was utilized to monitor changes in subjects' RPEs as a result of practice effects developed through repeated bouts of treadmill running. Results revealed that the treatment group's local and general RPEs for the over striding runs (+14%, +7%) were significantly greater (p < .01) than RPEs recorded during the FCSL run. Additionally, there was a marginally significant difference (p < .05) in local RPEs between the FCSL run and the extreme understriding run (?14%). Analysis of variance on the control group's RPE data suggests that neither local nor general RPEs changed significantly in repeated FCSL runs across the six-week testing period. The results of this study suggest that experienced recreational runners perceive differences in exertion accompanying changes in stride length.     

A Field Test for Upper Body Strength and Endurance

Abstract

Historically, a measure of upper body strength and endurance has been included in fitness test batteries that are typically administered in the school setting. Pull-ups, or some modified form of pull-ups, have been the most popular test item used for the measurement of upper body strength and endurance. Despite the widespread usage of pull-ups, the test has often been criticized because of the large number of zero scores and the subsequent loss of discrimination among ability levels (Jackson & Griffin, 1983). The inability to achieve a score is perceived as failure on the part of the student.     

Levels of Aspiration of High- and Low-Skilled Boys

Abstract

The stated levels of aspirations (L/A's) of high-skilled and low-skilled boys were examined to determine if they differed under prearranged conditions of failure in a simple motor task. Subjects were selected on the basis of their performances on a modified form of the Iowa Brace test. The motor task consisted of moving small blocks from one board to another. Preceding each of three trials, the subjct stated how many blocks he reasonably thought he could move in the succeeding 30-second trial. After a universal performance level was established, failure was induced by systematically stopping the subject before he attained his L/A. A 2×3 factorial design with repeated measures on the second-factor was employed. Analysis of variance indicated that the main effects of skill level and trials were significant at the .05 level. Analysis of simple effects indicated that the L/A's of the high- and low-skilled groups differed significantly only on the third trial (p = .05) and that failure had a significant effect on both groups (p = .10). High-skilled subjects expressed higher L/A's than did low-skilled subjects. All subjects' L/A's lowered significantly over trials. The L/A's of the high-skilled group as compared to the low-skilled group over the three trials did not indicate differential responses.     

Spanking and Child Development During the First 5 Years of Life

Using data from the Fragile Families and Child Wellbeing Study (N = 3,870) and cross‐lagged path analysis, the authors examined whether spanking at ages 1 and 3 is adversely associated with cognitive skills and behavior problems at ages 3 and 5. The authors found spanking at age 1 was associated with a higher level of spanking and externalizing behavior at age 3, and spanking at age 3 was associated with a higher level of internalizing and externalizing behavior at age 5. The associations between spanking at age 1 and behavioral problems at age 5 operated predominantly through ongoing spanking at age 3. The authors did not find an association between spanking at age 1 and cognitive skills at age 3 or 5.     

A Case Study of ROI in Organizational Performance of Working at Home

With the growing suburban population, many employees in metro areas are facing long commutes to and from the workplace. According to the 2011 Texas Transportation Institute's Urban Mobility Report, the average commuter experiences 34 hours of delay per year and spends an extra $713 on fuel (see http://tti.tamu.edu/documents/mobility‐report‐2011.pdf ). This not only causes stress for the employee but also has a serious impact on the organization and the environment.     

Reading skill components and impairments in middle school struggling readers

This study investigated how measures of decoding, fluency, and comprehension in middle school students overlap with one another, whether the pattern of overlap differs between struggling and typical readers, and the relative frequency of different types of reading difficulties. The 1,748 sixth, seventh, and eighth grade students were oversampled for struggling readers (n = 1,025) on the basis of the state reading comprehension proficiency measure. Multigroup confirmatory factor analyses showed partial invariance among struggling and typical readers (with differential loadings for fluency and for comprehension), and strict invariance for decoding and a combined fluency/comprehension factor. Among these struggling readers, most (85 %) also had weaknesses on nationally standardized measures, particularly in comprehension; however, most of these also had difficulties in decoding or fluency. These results show that the number of students with a specific comprehension problem is lower than recent consensus reports estimate and that the relation of different reading components varies according to struggling versus proficient readers.
