Decrease in pulmonary diffusion capacity after maximal exercise

Oppression of the chest, cough and orthopnea are well known to occur in some athletes after competitions, maybe reflecting an increase in lung water. In order to indicate if lung water increases after maximal exercise we measured pulmonary diffusion capacity before and 2.1 h after a short maximal arm exercise bout in 11 canoeists and showed a decrease of 6.7%. The result may be explained by a calculated 17% increase in alveolar interstitial volume.     

Code of practice for the pastoral care of international students: making a globalising industry in New Zealand

Export education in New Zealand has grown rapidly since 1990, earning significant foreign exchange and underwriting the finance of domestic education. As principal owner of education institutions, the national state is the primary investor. Previous governments treated the ‘industry’ as both windfall and cash‐cow as they advanced the neo‐liberal project of disentangling state from economy and making education providers self‐regulating. The current ‘Third Way’ inspired government has adopted a more prominent management interest in the making of this globalising industry. A new Code of Practice enacts multiple technologies of control from quality control to standard setting, benchmarking, certification and audit. Legitimated by a discourse of concern for the pastoral care of school‐aged students, it requires institutions to provide detailed information. The Code makes ‘the industry’ visible, makes a market, controls brand NZ education, regulates through consumer assurance, and imposes direct disciplinary controls on institutions. The Code of Practice makes apparent the ambitions and governmental technologies of the ‘augmented’ neo‐liberal state, and is a pivotal structure in the constitution of the industry and of the globalising processes that define it. The paper uses governmentality analysis to uncover these technologies of control and to consider their part in the constitution of both industry and globalisation.     

Reading Literacy Performance in Norway: current practice and critical factors

This qualitative study explored reading literacy performance of Norwegian students (Grades 1–10). Semistandardised interviews were conducted with 36 academics, school administrators, and teachers to investigate reading literacy development, factors associated with literacy performance, and recommendations for improvement. Reading literacy lessons were also observed in 10 classrooms to determine how reading literacy is developed. Data from the International Association for the Evaluation of Educational Achievement study ( Elley, 1994 ) and the Programme for International Student Achievement study ( OECD, 2001 ) were analysed to enrich understanding of the Norwegian literacy situation. Recommendations include greater reading education for teachers, communication and collaboration between stakeholders, engagement and interest in reading, balanced reading instruction, development of linguistic awareness, use of early intervention programmes, explicit strategy instruction, and use of bilingual education.     

Educating in the Seventh Fire: Debwewin,Mino‐bimaadiziwin,and Ecological Justice

The Anishinaabe Seven Fires Creation Story can be read as a theory on which all human beings share a fundamental love of reflecting reality in what they think and do. In this article, Marc Kruse, Nicolas Tanchuk, and Robert Hamilton argue that this ethical theory is correct but that the colonial ideology taught in our schools can obscure our knowledge of this fact. Specifically, the authors claim that decolonizing education requires teaching students and teachers alike to see the presence of value whenever they encounter other beings animated by a responsiveness to reality. All living things strive to perceive and respond to reality — to live and continue to learn — even if epistemic faculties differ. All living things, then, the authors conclude, are rightly seen as our relatives and kin, as bearers of value to whom we owe moral respect, as Anishinaabe elders have long taught.

Profiles of Childhood Maltreatment: Associations with Sexual Risk Behavior during Adolescence in a Sample of Racial/Ethnic Minority Girls

This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development.     

Aging and tennis playing in a coincidence-timing task with an accelerating object: the role of visuomotor delay

The purpose of the present study was to determine whether playing a specific ball sport, such as tennis, could maintain the coincidence-timing (CT) performance of older adults at a similar level to that of younger ones. To address this question, tennis players and nonplayers of three different age ranges (ages 20-30, 60-70, and 70-80 years) performed a simple CT task consisting of timing their response (pressing a button) to coincide with the arrival of a stimulus at a target. The stimulus moved at either an accelerating, constant, or decelerating velocity. As expected, all participants were affected by the velocity manipulation, which led to late and early responses to accelerating and decelerating stimuli, respectively. Whereas this response bias was increasingly pronounced with advancing age in nonplayers, no difference was found among player groups of different ages. Finally, we showed that the length of the visuomotor delay could explain the effect of nonconstant velocities.     

Explaining parental coviewing: The role of social facilitation and arousal

This study explores the relationship between parental coviewing and children’s psychophysiological responses to television exposure within a framework of social facilitation. A total of 88 children aged 6–13 years and one of each of their parents participated in a 2 (presence or absence of the parent)?×?2 (exciting or non-exciting TV content) between-subjects experiment. Results indicated that the presence of a coviewing parent was associated with an increase in children’s arousal (higher skin conductance levels) and cognitive resource allocation (lower heart rate), especially for younger children who came from homes where parental coviewing was a relatively frequent activity. These findings suggest that the mere presence of a coviewing parent is sufficient to alter children’s processing of television messages.     

The complex route to success: complex problem-solving skills in the prediction of university success

Successful completion of a university degree is a complex matter. Based on considerations regarding the demands of acquiring a university degree, the aim of this paper was to investigate the utility of complex problem-solving (CPS) skills in the prediction of objective and subjective university success (SUS). The key finding of this study was that CPS was not only strongly correlated to objective university success but also explained university grade point averages (GPA) of N?=?78 German business students even after intelligence and high-school GPA were controlled for. In addition, priority setting while working on a complex problem explained self-rated SUS. Given this incremental validity over the most established predictors of objective university success and its versatility, we argue that CPS may be a valuable addition to existing predictors in university applicant selection.
