Neuromuscular fatigue induced by an isotonic heavy-resistance loading protocol in knee extensors

Abstract

The main aim of this study was to assess neuromuscular fatigue during a typical high-load, low-repetition loading protocol. Muscle stimulations were used to assess maximum voluntary contraction, resting single- and double-pulse twitch characteristics, and superimposed double-pulse twitch force (used to calculate voluntary activation) before and after an acute knee extension loading protocol. In our participants, who had previous resistance training experience, the mean voluntary activation level was 96.2% in an unfatigued state. Maximum voluntary contraction (?11.8%), resting double-pulse twitch force (?10.6%), and voluntary activation (?2.1%) were markedly decreased as a consequence of loading (P < 0.05). In addition, although potentiated twitch characteristics were observed during the loading protocol, this was short-lived, as fatigue surpassed the potentiation mechanisms. Our results show that both central and peripheral mechanisms contributed to neuromuscular fatigue during the present loading protocol.     

Fostering Students’ Collaborative Learning Competencies and Professional Conduct in the Context of Two Gross Anatomy Courses in Veterinary Medicine

Collaborative learning has been used in anatomy courses to support students’ learning of challenging topics but the success of group work depends significantly on the students’ ability to communicate in a professional manner. Veterinary students’ experiences with tasks related to collaborative learning and professional conduct were studied by comparing learning collaborative competences and pedagogy, as well as perceived positive and challenging aspects, in two gross anatomy courses. Both qualitative and quantitative data were collected from students’ experiences of course assignments and collaboration, as well as from self-evaluated collaboration competence development. Trying things out oneself, practical application and professional conduct were positively highlighted particularly in the first-year course (myology and arthrology) group work and learning from others more in the second year (topographical anatomy). Various group work challenges, often relating to practical matters or communication, were the key concerns for students. The main difference between the two courses in learning of collaborative knowledge work competencies appeared to relate to the nature of the group work assignment. The topography course included the element of collaboration in preparing a presentation and teaching session for the rest of the class. Interestingly, students on the myology and arthrology course gave more positive comments on professional conduct than the students on the topography course despite the fact that the latter course included more practical elements relating to their future profession.     

The prevalence of publicly stimulated innovations –A comparison of Finland and Sweden, 1970–2013

While the role played by the state in stimulating innovation in the private sector has been a prevalent interest in innovation research, studies analysing the impacts of public interventions have usually focused on individual policies, programs or projects. Public stimulation is hence often studied from a relatively restricted and temporarily confined perspective, leaving a macro-level and longer-term perspective unrecognized. This article provides further evidence on the matter by examining how many innovations in Finland and Sweden have been publicly stimulated through funding or research collaboration, over a period of more than four decades (1970–2013). Our main source is a new innovation database constructed following the Literature Based Innovation Output (LBIO) method, which gathers the most significant innovations of both countries for the study period, totalling approximately 4100 Swedish and 2600 Finnish innovations. Our results indicate that the public sector has played a very prominent role in stimulating private innovation in both countries, and with an increasing trend. This is especially true for Finland, where 35–55% of the innovations of the period have been stimulated by public funding and 25–65% by collaboration with public research. In Sweden, the share of publicly stimulated innovations has been somewhat lower and erratic, but has increased over time.     

Strategy and Quality Maps in Higher Education

The purpose of this study is to investigate the integration of strategic management and quality assurance in higher education. The study presents how the value chain can be described in the strategy and quality maps, which are, respectively graphical representations of the strategic plan and the quality assurance system. The quality map is a new concept that explicitly takes into account the environment, strategic planning and the quality cycle of the institution. The quality map helps the management of the higher education institution present an overview of the quality assurance system to external evaluators, members of the organization, students and other stakeholders.     

Agents of responsibility in software vulnerability processes

Modern software is infested with flaws having information security aspects. Pervasive computing has made us and our society vulnerable. However, software developers do not fully comprehend what is at stake when faulty software is produced and flaws causing security vulnerabilites are discovered. To address this problem, the main actors involved with software vulnerability processes and the relevant roles inside these groups are identified. This categorisation is illustrated through a fictional case study, which is scrutinised in the light of ethical codes of professional software engineers and common principles of responsibility attribution. The focus of our analysis is on the acute handling of discovered vulnerabilities in software, including reporting, correcting and disclosing these vulnerabilities. We recognise a need for guidelines and mechanisms to facilitate further improvement in resolving processes leading to and in handling software vulnerabilities. In the spirit of disclosive ethics we call for further studies of the complex issues involved.     

Farmers’ Perceptions of Necessary Management Skills in Finland

Abstract

The main aim of this pre-study was to provide a preliminary overview of Finnish farmers’ motivation and capacity prerequisites for adopting and improving their management skills. Motivation was studied by asking farmers what farm management tasks and skills they consider important. Capacity was evaluated by asking farmers to rank management tasks and skills according to their perceived difficulty. Data (n=130) were collected by means of a questionnaire that was sent to a selected group of insured of the Finnish Farmers’ Social Insurance Institution. The most challenging management tasks and topics, that is, those to which most farmers gave high ratings in terms of both importance and difficulty, consisted of applying for subsidies and getting information on them, of the investment decision process, and of maintaining safety, health, and the ability and motivation to work. These are the main areas that should receive more attention in full-time education curriculums and extension initiatives.     

Curricular Reform,Constantly Changing Values and Consequences for Teacher Education

In many European countries revised notions of learning and the dynamic nature of knowledge have brought about changes in teaching in primary education. The new views of learning, together with profound social changes, have similarly created pressures for curricular reform. This paper examines the repercussions of extensive curricular reform for teacher education, especially with respect to what can be done to develop teachers’ didactic skills and capabilities for curricular planning. The latter calls for profound skills and a sensitivity in following the changes taking place in society, and also the ability to discuss the values towards which the concrete goals of the teaching should be directed. In order to convey such skills successfully, teacher education itself should clarify its position on its didactics and its philosophy. Didactics should not be simply a matter of communicating facts, but rather the emphasis in this respect should be shifted towards philosophical content, leading to the skills of independent thinking.     

The effect of wind on jumping distance in ski jumping – fairness assessed

The special wind compensation system recently adopted by Fédération Internationale de Ski (FIS; International Ski Federation) to consider the effects of changing wind conditions has caused some controversy. Here, the effect of wind on jumping distance in ski jumping was studied by means of computer simulation and compared with the wind compensation factors used by FIS during the World Cup season 2009/2010. The results showed clearly that the effect of increasing head/tail wind on jumping distance is not linear: +17.4 m/ ? 29.1 m, respectively, for a wind speed of 3 m/s. The linear formula used in the trial period of the wind compensation system was found to be appropriate only for a limited range of jumping distances as the gradient of the landing slope slows down the rate of distance change in long jumps.     

Metafictive Geography

Abstract

The imagining of space has been an important topic in recent geographical studies. Especially in the geographical study of literature, ‘literary geography’, the manner of contesting the frames of ‘fact’ and ‘fiction’ has aroused more and more attention during recent years. Metafiction, consciousness of a text’s own imaginativeness and the discourses behind it, has not yet been explicitly discussed in the field of literary geography, although some tangential approaches have been applied. The main purpose of this paper is to discuss how the metafictive reading of literature functions as an alternative way of approaching the imagining of space, offering an original ‘methodological’ viewpoint for perceiving space, culture and society. The specific focus is on how space becomes metafictive through literary ‘means’ such as divergent narrative and textual strategies, exceptional typographies and ironic writing. At the same time the paper considers how the metafictive continuum between the frames of ‘fact’ and ‘fiction’ may function as a tool for delving more deeply into the discursiveness of the human imagination.     

How do Finnish children express care and justice in comic strips and written narratives?

This case study explored how children’s moral expressions like love and violence differ according to the mode of narrative, comic strips or written narratives. Sixteen third-grade children from a primary school in Finland took part in the study. Children’s moral expressions were divided into justice and care. Reading frequency of fairy tales and linguistic and artistic abilities were also assessed in order to make a more in-depth interpretation of elements that underlie these different moral voices. The data for four of the children are presented in detail as the basis for the discussion. Children expressed their morality more strongly in comic strips—potentially offering a more sophisticated method for examining how children express their morality.
