The effect of inspiratory muscle fatigue on acid-base status and performance during race-paced middle-distance swimming

The aim of this study was to investigate the effect of pre-induced inspiratory muscle fatigue (IMF) on race-paced swimming and acid-base status. Twenty-one collegiate swimmers performed two discontinuous 400-m race-paced swims on separate days, with (IMF trial) and without (control trial) pre-induced IMF. Swimming characteristics, inspiratory and expiratory mouth pressures, and blood parameters were recorded. IMF and expiratory muscle fatigue (P < 0.05) were evident after both trials and swimming time was slower (P < 0.05) from 150-m following IMF inducement. Pre-induced IMF increased pH before the swim (P < 0.01) and reduced bicarbonate (P < 0.05) and the pressure of carbon dioxide (PCO₂) (P < 0.05). pH (P < 0.05), bicarbonate (P < 0.01) and PCO₂ (P < 0.05) were lower during swimming in the IMF trial. Blood lactate was similar before both trials (P > 0.05) but was higher (P < 0.01) in the IMF trial after swimming. Pre-induced IMF induced respiratory alkalosis, reduced bicarbonate buffering capacity and slowed swimming speed. Pre-induced and propulsion-induced IMF reflected metabolic acidosis arising from dual role breathing and propulsion muscle fatigue.     

Metacognitive strategies and reading comprehension in elementary-school students

The aim of this study was to explore comprehension monitoring and perceived use of reading strategies as factors of reading comprehension. Participants were elementary school students from the fifth to the eighth grade. Error correction and text sensitivity tasks from the Metacomprehension test (Pazzaglia, De Beni, &; Cristante, 1994). and the cloze-task were used as measures of comprehension monitoring during reading. A Strategic reading questionnaire (Koli?-Vehovec &; Baj?anski, 2001b) was applied as a measure of perceived use of strategies during reading. Girls had better results than boys on text comprehension, all measures of comprehension monitoring, as well as on the Strategic reading questionnaire. Significant developmental improvements in comprehension monitoring occurred after the fifth grade and between the sixth and the eighth grade. A similar change was evident in reading comprehension. All measures of comprehension monitoring were significantly related to text comprehension in all age groups. However, perceived use of reading strategies was significantly related to reading comprehension only in eighth-grade students.     

That’s Not For Our Kids: The strange death of philosophy and ethics in a low socioeconomic secondary school

Abstract

This article reflects on the successes and failures of a new Philosophy and Ethics course in a low socioeconomic context in Perth, Western Australia, with the eventual demise of the subject in the school at the end of 2010. We frame this reflection within Deleuzian notions of geophilosophy to advocate for a Philosophy and Ethics that is informed by nomadic thought, as this offers a critical freedom for students to transform themselves and their society and suggests practical ways both of overcoming the prejudices which led to its demise and of student reluctance to engage in open discussion in class. We consider the demise of the course a ‘missed opportunity’ because it had so much potential to be transformative of student subjectivities in schools.     

Complexity leadership in learning analytics: Drivers,challenges and opportunities

Learning analytics (LA) has demonstrated great potential in improving teaching quality, learning experience and administrative efficiency. However, the adoption of LA in higher education is often beset by challenges in areas such as resources, stakeholder buy-in, ethics and privacy. Addressing these challenges in a complex system requires agile leadership that is responsive to pressures in the environment and capable of managing conflicts. This paper examines LA adoption processes among 21 UK higher education institutions using complexity leadership theory as a framework. The data were collected from 23 interviews with institutional leaders and subsequently analysed using a thematic coding scheme. The results showed a number of prominent challenges associated with LA deployment, which lie in the inherent tensions between innovation and operation. These challenges require a new form of leadership to create and nurture an adaptive space in which innovations are supported and ultimately transformed into the mainstream operation of an institution. This paper argues that a complexity leadership model enables higher education to shift towards more fluid and dynamic approaches for LA adoption, thus ensuring its scalability and sustainability.     

Research Circles: Supporting the Scholarship of Junior Faculty

This article describes and assesses “Research Circles” as a mechanism for enhancing faculty collegiality and research. Recently established on our campus, these circles, composed of three to four faculty members, have had a particularly powerful effect on the new faculty members' adjustment to their tenure track positions, especially since they entered a context that might otherwise have been challenging: a new interdisciplinary upper-division campus with high expectations for teaching excellence. Based on the end-of-year evaluations, journals, and focus groups, the co-authors described themes that emerged from their participation in these circles. Circle participation not only facilitated faculty writing throughout their first year, but it also fostered the development of an interdisciplinary community which nurtured creativity and risk taking in writing.

Identification of discipline violations and its role in planning corrective and preventive discipline in school

Many surveys confirm a substantial number of discipline problems in schools, but not many surveys are aimed at their identification. Identification of discipline violations is indispensable for prudent planning of their interventions in and prevention of their occurrence. Earlier studies focused mostly on the teachers’ perceptions of discipline problems and they were not interested in how discipline problems are perceived by students. In this study, teachers and students identified the most frequent and disturbing discipline violations. Given the results of the survey, it would be necessary to pay more attention to preventing disruption of lessons and improper attitude, which are, in the views of teachers and students alike, the most frequent and disturbing violations.     

Development of Math Attitudes and Math Self-Concepts: Gender Differences,Implicit–Explicit Dissociations,and Relations to Math Achievement

Three hundred and ninety-one children (195 girls; M_age = 9.56 years) attending Grades 1 and 5 completed implicit and explicit measures of math attitudes and math self-concepts. Math grades were obtained. Multilevel analyses showed that first-grade girls held a strong negative implicit attitude about math, despite no gender differences in math grades or self-reported (explicit) positivity about math. The explicit measures significantly predicted math grades, and implicit attitudes accounted for additional variance in boys. The contrast between the implicit (negativity for girls) and explicit (positivity for girls and boys) effects suggest implicit–explicit dissociations in children, which have also been observed in adults. Early-emerging implicit attitudes may be a foundation for the later development of explicit attitudes and beliefs about math.     

Social inequalities in access to higher education in Croatia: five decades of resilient findings

This article provides a panoramic view of research findings on social inequalities in access to higher education in Croatia since the 1960s, guided by the question of what has changed in the findings. Our review shows that there is stark continuity over the last five decades: students from better educated family backgrounds tend to be overrepresented in higher education; students from better educated and white-collar family backgrounds are more likely to enrol in academic as opposed to professional study courses; students at one Croatian university in particular stand out in terms of their more privileged social background; and medicine seems to be the prime academic field for observing social reproduction. We note that these persistent findings run parallel to a dramatically changing political, economic and social context in Croatia, including transformations in the 1990s resulting from social ownership of the means of production to widespread private ownership, as well as transformations from a one-party political system to the establishment of a multi-party political system. The article maps possible theoretical explanations for the resilience of social inequalities in access to higher education in the context of dynamic times. It also questions the role of educational policies in this process.     

Shedding the content: semantics of teaching burdened by didactic formalisms

The paper argues that what is left behind in the current era of accountability is the educational content. The authors present shedding the content as the great challenge of teaching and learning in today’s schools. They turn to the tradition of Bildung and outline the theoretical background for the content-focused approach to (research on) teaching and learning. Their approach is based on analyses of authentic (real-life) teaching and learning situations. The paper highlights how didactic case studies can be used to generalize the findings across individual cases. Within the multiple case studies, 44 didactic case studies were reanalysed to identify didactic formalisms, i.e. problems in the semantic and logical structure of educational content, which corrupt the quality of instruction. Two specific types of didactic formalism are described in detail; stolen cognition and concealed cognition. Stolen cognition prevents cognitive activation of students when the teacher over-reduces the space allowed for the students’ cognitive work with the content, concealed cognition are instances of purposeless cognitive activation of students due to their being disconnected from the content.     

Recommendations for effective university study based on students’ point of view

This research examined what university students recommend for effective university study and whether their recommendations differ by gender, faculty or study programme degree. The research was based on 985 questionnaires. The following words were most commonly used in advice for freshmen: Go, Lectures, Learn, Continuously, Be, Prepare, Information, Have, Do, Materials. The fundamental advice seems to be: to go to lectures, to have needed materials and information and to learn and prepare continuously. Some stated recommendations react to the development of information and communication technologies and the massive usage of the Internet (such as obtaining a laptop and a cell phone or setting up a Facebook profile). Quite a lot of advice was connected with health, such as to sleep enough, to eat regularly, to not smoke, to relax and to restrict alcohol consumption. The recommendations gained in this survey were categorised by thematic similarities to characteristics, knowledge, skills, behaviour and background. The findings highlight the fact that given recommendations for effective study differ by the respondent’s gender and faculty. Women concentrated more on recommendations on how to behave and men mentioned more often what personality characteristics are important for effective university study. Students of the Faculty of Multimedia Communications highlighted the necessity of creativity and practical experience more often than others.
