Inclusion and mastery: variations on the theme of subjection

This article undertakes a discursive analysis of the concepts of ‘inclusion’ and ‘mastery’ using memory stories generated in a collective biography workshop. The five authors analysed their memories from childhood and adolescence on two separate and competing concepts that currently inform educational practice: inclusion and mastery. These stories of mastery/non‐mastery and inclusion/exclusion often exceeded or transgressed dominant normative discourses concerning the competent performance of autonomous selves. Drawing on the work of several theorists, they authors explored these transgressions. In so doing, their analysis extends Butler’s theorising of the human subject as constituted through processes of exclusion and differentiation.     

Oxygen uptake kinetics in children and adults after the onset of moderate-intensity exercise

The literature suggests that the oxygen uptake (VO2) response to the onset of moderate-intensity exercise may be both mature from childhood and independent of sex. Yet the cardiorespiratory response to exercise and the metabolic profile of the muscle appear to change with growth and development and to differ between the sexes. The aim of this study was to investigate further changes in the VO2 kinetic response with age and sex. Participants completed a series of no less than four step change transitions, from unloaded pedalling to a constant work rate corresponding to 80% of their previously determined ventilatory threshold. Each participant's breath-by-breath responses were interpolated to 1 s intervals, time aligned and then averaged. A single exponential model that included a time delay was used to analyse the averaged response following phase 1 (15 s). Participants with parameter confidence intervals more than +/- 5 s were removed from the sample; the results for the remaining 13 men and 12 women (age 19-26 years), 12 boys and 11 girls (age 11-12 years) were used for statistical analysis. Children had a significantly shorter time constant than adults, both for males (19.0+/-2.0 and 27.9+/-8.6 s respectively; P<0.01) and females (21.0+/-5.5 and 26.0+/-4.5 s respectively; P<0.05). There were no significant differences in the time constant between the sexes for either adults or children (P>0.05). A significant relationship between the time constant and peak VO2 was found only in adult males (P<0.05). A shorter time constant in children may reflect an enhanced potential for oxidative metabolism.     

Boomers to Millennials: Generational Stereotypes at Work in Academic Librarianship

Over the past 30?years, as the American workforce has become more generationally diverse, library administrators and academic librarians alike have focused on navigating dynamics that arise in a multigenerational workplace. Much scholarly research has been conducted on generational differences; however, most of this research assumes that the individuals studied adhere to or believe in generational stereotypes. This exploratory study used a hybrid experience-perception survey to examine the role or influence generational stereotypes have on academic librarians and how those stereotypes influence the academic library workforce. While few specific generational stereotypes were found to be held by participants, perceptions of generational stereotypes still have a significant influence in academic librarians' interactions with their colleagues. This finding means that regardless of their validity, the impact of generational stereotypes cannot be disregarded in academic library workplaces.     

Social functioning among college students diagnosed with ADHD and the mediating role of emotion regulation

Despite the many studies that have documented the association between symptoms of ADHD and social difficulties in children and adolescents, few have examined this phenomenon in college students. In addition, the underlying factors contributing to such social difficulties are still poorly understood. We hypothesised that college students with symptoms of ADHD, namely inattention and hyperactivity/impulsivity, would continue to display social behavioural difficulties, and that emotion regulation would play a mediating role in that relationship. Ninety-nine 17–24-year-old college students filled out three questionnaires to assess Inattentive and Hyperactivity/Impulsivity Symptoms, Social Skills, and Emotion Regulation abilities. Analysis revealed that emotion regulation is a significant mediator between Inattentive Symptoms and Social Skills for female students. There was no significant correlation between ADHD symptoms and Social Skills for males. Female college students report social functioning difficulties associated with their inattentive and hyperactive symptoms, and impaired emotion regulation abilities mediate this relationship for inattentive symptoms only.     

Within-session changes in responding during delayed matching-to-sample and discrimination procedures

Two experiments examined within-session changes in responding during discrimination procedures. In Experiment 1, rate of responding changed significantly within sessions during symbolic delayed matching-to-sample tasks when the delay between the stimulus and the choice period was short (1–5 sec), but not when it was long (8–12 sec). The percentage of responses that were correct did not change within sessions. In Experiment 2, response rates increased and then decreased within sessions during both S1 and S2 when successive discrimination procedures provided high, but not low, rates of reinforcement. Discrimination ratios sometimes increased within sessions. These results question two potential definitions of attention as explanations for within-session changes in response rates. They are more compatible with explanations based on concepts such as arousal, satiation, habituation, and interfering responses.
