Strength training: isometric training at a range of joint angles versus dynamic training

Strength training with isometric contractions produces large but highly angle-specific adaptations. To contrast the contractile mode of isometric versus dynamic training, but diminish the strong angle specificity effect, we compared the strength gains produced by isometric training at four joint angles with conventional dynamic training. Thirty-three recreationally active healthy males aged 18 - 30 years completed 9 weeks of strength training of the quadriceps muscle group three times per week. An intra-individual design was adopted: one leg performed purely isometric training at each of four joint angles (isometrically trained leg); the other leg performed conventional dynamic training, lifting and lowering (dynamically trained leg). Both legs trained at similar relative loads for the same duration. The quadriceps strength of each leg was measured isometrically (at four angles) and isokinetically (at three velocities) pre and post training. After 9 weeks of training, the increase in isokinetic strength was similar in both legs (pooled data from three velocities: dynamically trained leg, 10.7%; isometrically trained leg, 10.5%). Isometric strength increases were significantly greater for the isometrically trained leg (pooled data from four angles: dynamically trained leg, 13.1%; isometrically trained leg, 18.0%). This may have been due to the greater absolute torque involved with isometric training or a residual angle specificity effect despite the isometric training being divided over four angles.     

Ensuring the academic library's relevance to stakeholders: The role of the Library Director

This paper presents a substantive grounded theory about how the Library Director can ensure the library's relevance to university and external stakeholders in the face of rapid changes in technology and higher education. A constructivist grounded theory research approach involved 14 semi-structured interviews with 12 Library Directors of publicly funded university libraries in Australia and the United States. The substantive theory and the conceptual model presented in this paper suggest that the Library Director responds to the problem of rapid change by enacting the following strategies: aligning strategic vision with the university; continuously reinventing the library; engaging with stakeholders; building an agile and engaged culture; and demonstrating value to the university. The strategies interact with each other in a cyclical pattern. This is an original theory that emphasizes the important role of the Library Director as the agent and model for library strategy and culture. The theory requires library leaders to be strategic thinkers and to be engaged in strategic planning processes that aim for continuous improvements that make the library agile and engaged with stakeholders. The theory also has a significant impact upon the behaviours required for all library staff members.     

Enhancing student engagement in one institution

Student engagement is important to further and higher education institutions: it is understood to be a proxy for quality teaching and governments attach a proportion of funding to student retention and completion. Many institutions are taking part in student engagement surveys, using the data generated to initiate changes to policies and practice. This article presents an overview of literature on student engagement and quality teaching. It then briefly describes three projects in one institution in New Zealand that were designed to improve teaching and student engagement, and outlines key findings from them. The projects are then related to four of Chalmers’ five levels of quality teaching and Leach and Zepke’s six perspectives on engagement, enabling some conclusions about what Massey University is doing successfully and what more it could do to enhance student engagement. It is suggested that other institutions could use this different approach to review their current pedagogy and student engagement strategies.     

How do parents acquire information to support their child with a disability and navigate individualised funding schemes?

With the international trend towards individualised funding packages that allocate funds to individuals to spend on disability support needs, the challenge of ensuring parents can readily access useful information to make decisions becomes paramount. The present research used a two stage, mixed method sequential approach (with 291 parents surveyed and 56 parents participating in focus groups) to determine how parents acquire information to enhance their understanding of their child's disability and determine how to use an individualised funding scheme to benefit their child and family. Parents attested to the importance of person‐to‐person communication and valued information that originated from other parents of a child with a disability, and from professionals who knew their child. Parents also spoke about the limitations of the internet, noting that reliance on the internet could cause confusion as the validity of information could not be assured. Early childhood intervention services emerged as a key instrument in developing the capacity of families to make informed choices. Understanding families'’ perspectives on the utility of information sources is critical and timely as policy‐makers and service providers within the disability sector shift practice to meet the rise of individualised funding internationally.     

Spaces of inclusion: investigating place,positioning and perspective in educational settings through photo-elicitation

This paper presents findings from a collaborative research study which sought to explore perspectives and understandings of the concept of inclusion, as played out in schools and colleges in northwest England, via the use of images. The research had two parts: in the first part, children and young people took photographs in their school setting that they felt represented inclusion or exclusion, offering an explanation for their choice. Some of these photographs and the accompanying comments were anonymised and formed the second part of the research that sought the viewpoints and perspectives of student-teachers, serving teachers, teaching assistants and academics via seminars and workshops. It is the responses received in the seminars and workshops that form the focus of this paper. Four images and a range of responses to them have been selected for discussion and are framed within three key inter-related themes of place, positioning and perspective. Such an analysis is made to consider how self-positioning might inform diverse interpretations of the cultural construction and visual representation of inclusion and exclusion.     

Digital play: a new classification

Abstract

This paper draws on an ESRC-funded study of play and creativity in preschool-aged children’s use of apps in the UK. The main objectives of the study were to collect information about access to and use of apps in the home, establish the most popular apps and identify the features of those apps that are successful in promoting play and creativity. A mixed-method approach was used to collect data, including video filming of children using the most popular apps. In identifying play types that emerged in the analysis of data, the team utilised an established taxonomy, which outlines sixteen play types. This taxonomy was reviewed and adapted to analyse data from the project relating to digital play. Through this process, an additional type of play, transgressive play, was identified and added to the taxonomy. The paper outlines the implications of the revised taxonomy for future studies of play.     

A General 3-Step Maximum Likelihood Approach to Estimate the Effects of Multiple Latent Categorical Variables on a Distal Outcome

The 3-step approach has been recently advocated over the simultaneous 1-step approach to model a distal outcome predicted by a latent categorical variable. We generalize the 3-step approach to situations where the distal outcome is predicted by multiple and possibly associated latent categorical variables. Although the simultaneous 1-step approach has been criticized, simulation studies have found that the performance of the two approaches is similar in most situations (Bakk & Vermunt, 2016). This is consistent with our findings for a 2-LV extension when all model assumptions are satisfied. Results also indicate that under various degrees of violation of the normality and conditional independence assumption for the distal outcome and indicators, both approaches are subject to bias but the 3-step approach is less sensitive. The differences in estimates using the two approaches are illustrated in an analysis of the effects of various childhood socioeconomic circumstances on body mass index at age 50.     

Choosing letter grade evaluations: The interaction of students’ achievement goals and self-efficacy

We examined how achievement (learning and performance) goals and academic self-efficacy predicted three achievement-related outcomes in a college sample. Self-efficacy tended to moderate the effects of (learning and performance) goals on number of courses taken for a letter grade as well as achievement in letter graded and pass/fail courses. Thus, learning goals better predicted choosing letter grades when self-efficacy was high than when it was low. In contrast, performance goals better predicted choosing letter grades when self-efficacy was low than when it was high. Through their prediction of the choice to receive letter grades these interactions predicted achievement in pass/fail courses. In addition, achievement goals and self-efficacy directly predicted achievement in letter graded courses.
