Reproducibility of upper leg EMG frequency content during cycling

Reproducibility of frequency content from surface electromyography (sEMG) signals has not been assessed and it is unknown if incremental load testing design could affect sEMG in cycling. The goals of this study were to assess the reproducibility of measures from sEMG frequency content between sessions and to compare these frequency components between a ramp and a step incremental cycling test. Eighteen cyclists performed four incremental load cycling tests to exhaustion. Two tests were performed using a step increment (load started at 100 W for 3 min followed by increments of 30 W every 3 min) and two were performed using a ramp increment (load started at 100 W for 1 min followed by increments of 30 W·min^?1). sEMG was monitored bilaterally for the rectus femoris and vastus lateralis throughout the tests and converted into overall activation (whole signal bandwidth), high- and low-frequency contents. The reproducibility of the frequency content ranged from none to strong (ICC = 0.07–0.90). Vastus lateralis activation was larger at the step compared to the ramp test (P < 0.01), without differences for rectus femoris (P = 0.22–0.91) and for the high-frequency (P = 0.28–0.95) and low-frequency contents (P = 0.13–0.94). sEMG from vastus lateralis and rectus femoris presented none to strong reproducibility. Vastus lateralis is more activated in step test design.     

Facilitating adult learning and a researcher identity through a higher education pedagogical process

This empirical study uses auto-ethnography to describe a higher education pedagogical process that facilitated largely doctoral students in preparing their candidacy proposals through the use of specific adult learning principles. Students＇ experiences and points of view of such a learning environment were explored, including： （1） how they contributed to their peers＇ learning; （2） how their peers contributed to their own individual learning; and （3） how the learning environment impacted the process. Key factors identified as pivotal to learning to learn, include creating a learning sanctuary and trusting relationships, engaging in mutual inquiry and the co-construction of meaning, and bridging research theory and practice. These factors enabled students to expand their identities to include a researcher identity and to negotiate deep knowledge at the personal level. Throughout this article, the students＇ points of view are used to elucidate shared and diverse experiences, in addition to supporting conclusions and recommendations for practice and further study.     

Outdoor play as a mean to achieve educational goals - a case study in a Portuguese day-care group

This study aims to explore the pedagogical potential of outdoor play situations, considering the educational goals established in the Portuguese Pedagogical Guidelines for 0–3-year-old children (ongoing work), namely development of a sense of security and positive self-esteem; development of curiosity and exploratory impetus; and development of social and communication skills. Following a qualitative methodology, during a period of 9 months, the outdoor play experiences of 14 children from a day-care centre were observed and monitored and the professionals were interviewed. The data shows that outdoor experiences can contribute to the achievement of the educational goals, enlarging opportunities for creative play, problem solving, experimentation, inquiry, dialogues and collaboration. The achievement of the educational goals is facilitated through supportive and positive relationships with adults and peers, provision for proper equipment, and contact with nature. This study offers a deep insight into how educational policies can be put into practice in the outdoor area.     

Impact of interdisciplinary learning on the development of engineering students’ skills

ABSTRACT

This paper intends to present an interdisciplinary project carried out in a School of Engineering, and to refer to its effects in the development of students’ skills. This project’s main goal was to present students with an intellectually demanding challenge which implied overcoming the disciplinary barriers thus integrating knowledge to solve the problems they were challenged with. After the project had been concluded, a study was carried out using a qualitative methodology by conducting two focus groups (n?=?16). The main goal of this procedure was to get a better perception of (1) how students understood the project; (2) what kind of skills students considered to have developed throughout the project, and (3) the importance they have attributed to this kind of project. The results demonstrate that students are aware of the relevance of the project not only for their education process but also for the development of their skills. The results of the study also reveal that the students involved in the project have been capable of identifying the specific skills that the project work had intended to address and develop.     

Team Effort – Training Therapists to Work with Interpreters as a Collaborative Team

This paper considers components of a framework for relational training for counsellors who work with interpreters. Where counsellors and clients cannot be linguistically matched, they will need to incorporate an interpreter into their therapeutic relationship. Counsellors are often unprepared to work in this way. ‘Mothertongue multi-ethnic counselling service’, a UK counselling agency has developed and piloted an in-house training for counsellors and interpreters. Components of this training in how to work collaboratively with interpreters are considered in this paper. These components address the need for a collaborative relationship between counsellor and interpreter, consideration of dynamics in a triangular relationship and a clear delineation of responsibilities. Recommendations are made for the development of a training curriculum and models of clinical supervision for counsellors and interpreters who want to work together collaboratively.     

Technical replicas of Portuguese ceramic tile bodies produced in the Oporto region in the late nineteenth to early twentieth centuries

Portugal is well known for its facades decorated entirely with ornamented glazed ceramic wall tiles called azulejos. On ageing, the tiles may detach and fall off, or deteriorate to such an extent that it becomes necessary to replicate them. Hence tile replication is a common practice in Portugal for façade restoration, but very often these new tiles do not have the same physical and/or chemical properties as the original ones. Such differences might be a factor in differential deterioration of the façades after restoration. One step toward an improvement in compatibility is to make new ceramic bodies with the same characteristics as the original ones. This study focuses on two types of glazed ceramic wall tiles from the Oporto region in Portugal: ‘calcic faience’ and pó de pedra. A total of 25 samples from the late nineteenth to early twentieth centuries were studied systematically as an attempt to improve knowledge of these materials and to create a basis for their replication. All samples were collected from facades that were under conservation/restoration at the time when sampling was performed. The original traditional ceramic bodies were analyzed by X-ray diffraction and X-ray fluorescence. Total open porosity, capillary absorption coefficient, and mercury intrusion porosimetry were also measured in order to gain knowledge on their physical characteristics in addition to their chemical and mineralogical compositions. High-temperature crystalline phases such as diopside, gehlenite, and mullite were found in the calcic faience, suggesting that the firing temperature of calcic faience bodies was within the range of 1100–1150?°C. Calcination trials were also performed in order to determine the most probable firing temperatures of the ceramic bodies. Collected data led to the assumption that the raw materials used for the ceramic bodies were kaolinitic clay, quartz sand, limestone, and talc. The raw materials for pó de pedra tiles were found to include kaolinite clay and quartz with firing temperatures estimated within the temperature range of 1150–1360?°C. Technical replicas made on the basis of these investigations were found to have the same mineralogical and capillary properties as the original tiles.     

Emotional intelligence throughout Portuguese secondary school: a longitudinal study comparing performance and self-report measures

This study examines the developmental trajectories of ability and trait emotional intelligence (EI) in the Portuguese secondary school. Within a three-wave longitudinal design, 395 students (M _age ?=?15.4; SD?=?.74) completed both the Emotional Skills and Competence Questionnaire (ESCQ) and the Vocabulary of Emotions Test (VET). Results revealed that EI exhibited different developmental trajectories during late adolescence according to the type of measure used, while students’ VET levels evidenced an increase during secondary school, their ESCQ levels remained stable during this period. Moreover, students’ gender, verbal indicator, and type of school (public vs. private) have no significant effect on their rate of EI change, whereas students from lower sociocultural and lower professional status backgrounds demonstrated significantly greater increases on the ESCQ and VET compared to higher status adolescents. The results are examined in the context of adolescent emotional development.     

Reconsidering the technologies of intellectual inquiry in curriculum design

This paper reports on the design and delivery of classroom pedagogies and students’ engagement with it in two different UK universities. Under the banner of curriculum design and Bourdieu's curriculum principles, the study set out to create modules that provided students with an interdisciplinary perspective on how the web is changing the way citizens live, interact and learn. Focusing on the idea that the web is becoming a tool of intellectual inquiry and an instrument of reproduction of knowledge inequality, the goal of this research was to transform knowledge practices by encouraging a learning habitus that relies on knowing how to learn rather than becoming ‘knowledgeable.’

The paper concludes that the Bourdieuian perspective on curriculum design still holds currency in the digital age, given that it shares an epistemology of practice similar to that advocated by a digital participatory culture. We also offer a critique to our approach, using Bourdieu's logic of practice to examine how education as a field displays (hidden) rules that students embody as their learning habitus. As students’ learning practices become doxified through their educational trajectories, learners find it difficult to engage with a curriculum that aims to diversify pedagogical structures and reflect a changing society.     

Student estrangement in higher education: identity formation and the struggle against stigma

Abstract

While investigation on family estrangement is growing within academic circles, research regarding the interconnection between experiences of estrangement and higher education (HE) is still limited. Sociological understandings of these issues are even scarcer, with policy interventions and practical guidance forming early interventions in HE. Set within the context of Scotland, this paper explores the experiences of HE students who are estranged from their family, and interrogates the ways students develop a sense of identity in the context of their academic lives. The paper applies Goffman’s work on stigma and identity management in relation to Bourdieu’s concept of capitals to cast a critical eye on the identity formation of estranged students. In doing so, we challenge normative assumptions of what it means to be a university student in contemporary society and urge institutions and policy makers to rethink the complexity of students’ academic lives in more inclusive ways.
