A comparative study on oxidative stress and antioxidant status in ischemic stroke patients with and without diabetes

The study was conducted to find out the extent of lipid peroxidation and antioxidant status in ischemic stroke patients (ISPs) with and without diabetes. Malondialdehyde (MDA) was studied as a marker of lipid peroxidation. Glutathione (GSH), uric acid and ceruloplasmin were estimated to study the antioxidant potential of ISPs. Significantly higher levels of MDA were found in both the groups of ISPs and the increase in MDA was more in ISPs without diabetes. GSH levels were decreased significantly in both the groups of ISPs and maximum decline was found in ISPs with diabetes. Uric acid levels were significantly increased in both the groups of ISPs. Ceruloplasmin levels were increased significantly in ISPs without diabetes, whereas its levels were slightly decreased in ISPs with diabetes. A negative correlation was found between MDA and the antioxidants GSH, uric acid and ceruloplasmin in ISPs with diabetes. This study suggests that there is an association between ischemic stroke and increased oxidative stress and the antioxidant potential is impaired in both the groups of ISPs with and without diabetes.     

Scenarios of quality assurance of stakeholder relationships in Finnish higher education institutions

Although the role and significance of the external stakeholders of higher education institutions has grown in recent years, quality assurance of stakeholder relationships remains a new phenomenon in the management practices of higher education institutions and in higher education research. Based on interviews and expert panel data, this article analyses the internal and external stakeholders’ perceptions of scenarios of the quality assurance of stakeholder relationships in Finnish higher education institutions. It especially focuses on exploring how institutions can balance internal and external stakeholders’ perspectives with regard to quality assurance. The results show that an essential challenge for Finnish higher education institutions is to develop flexible quality assurance practices capable of balancing the academic goals of the institutions and the needs of the external stakeholders. This also requires seeking balance between the centralised coordination and the differentiated practices of disciplines and academic units inside institutions.     

Blending in: reconciling feminist pedagogy and distance education across cultures

Distance education’s mandate to expand outreach to those with limited access to higher education makes it a particularly welcome mode for non-traditional women learners. Feminist pedagogy, which has tended to privilege the classroom space in the learning experience, has stopped short of a wholehearted acceptance of distance education which relies heavily on self-study and has become increasingly defined by technology aided learning in recent years. Despite this conflicted relationship, their shared democratising mandate and learner-centric approaches have made it possible to envision a rapprochement between the two. This has been aided by a revised understanding of ‘distance’, a dislodging of real/virtual dichotomies and an exploration of ‘hybrid’ spaces in the interest of feminist goals. After mapping these developments on an international canvas, I explore a similar reconciliation in the context of developing countries, specifically India. Here, I argue that despite the significance of democratisation, challenges posed by consumerist trends in mass-based open education call for suitable strategies, including a re-adaptation of the ‘hybrid’. Using the example of a ‘blended approach’ programme, I attempt to show how contextualised innovations may help to sustain the partnership between feminist pedagogy and Open & Distance Learning. It is hoped that such an illustration, despite its limitations and specificity, may provoke other experimentations in diverse socio-cultural contexts.     

Finnish pre-service teachers’ and upper secondary students’ understanding of division and reasoning strategies used

In this paper, we focus on Finnish pre-service elementary teachers’ (N?=?269) and upper secondary students’ (N?=?1,434) understanding of division. In the questionnaire, we used the following non-standard division problem: “We know that 498:6?=?83. How could you conclude from this relationship (without using long-division algorithm) what 491:6?=?? is?” This problem especially measures conceptual understanding, adaptive reasoning, and procedural fluency. Based on the results, we can conclude that division seems not to be fully understood: 45% of the pre-service teachers and 37% of upper secondary students were able to produce complete or mainly correct solutions. The reasoning strategies used by these two groups did not differ very much. We identified four main reasons for problems in understanding this task: (1) staying on the integer level, (2) an inability to handle the remainder, (3) difficulties in understanding the relationships between different operations, and (4) insufficient reasoning strategies. It seems that learners’ reasoning strategies in particular play a central role when teachers try to improve learners’ proficiency.     

The coming of a classical world

Quantum theory’s unusual predictions stem from its basic formalism which involves concepts like the wavefunction or probabilityamplitudes instead of probabilities. Many serious doubts have been raised about quantum theory’s connection with perceived classical dynamics. How does quantum mechanics, with all its strange ideas, unfold to give us the ‘reality’ of the familiar physical world? What is the connection between theclassical and thequantum! If quantum mechanics is, indeed, the fundamental theory of nature, as is widely accepted, then how does it explainclassicality! In the following, some of the fascinating conceptual problems of quantum mechanics are highlighted. The ‘environment-induceddecoherence’ approach is then discussed as one practical attempt at explaining the emergence of a classical world from an underlying quantum substrate     

Perceptions of Science and Technology: A Comparison of Criminal Justice and Traditional Science and Technology Majors

Due to the increased demands for science and technology (S&T) in criminal justice (CJ) occupational preparation and in response to the growing interest of students in forensics, this study explores the attitudes of CJ majors towards S&T. Despite the acknowledgment that S&T skills are helpful in gaining employment, CJ majors reported less favorable attitudes than S&T majors, reporting: less interest in gaining S&T knowledge, fewer social benefits of S&T, and greater concerns that S&T are dangerous to society than traditional forensic science majors. While these findings raise some fundamental questions about the suitability of increased representation of S&T courses within CJ curriculum, authors argue that CJ curricular goals must continue to evolve to foster innovative students who are academically prepared to meet the twenty-first century challenges of their future careers.     

The Rate and Delay in Overload: An Investigation of Communication Overload and Channel Synchronicity on Identification and Job Satisfaction

This study investigates the relationship between communication overload and uses of diverse communication channels in terms of their level of synchronicity. Emphasis on the synchronicity of any given channel reveals how temporal elements (i.e., rate and processing time) play an important role in perceptions of communication load. Additionally, this study examines the association between communication overload, organizational identification and job satisfaction. Findings reveal: (a) both high and low synchronous channels are associated with increased reports of communication overload; (b) a mediating effect of organizational identification on the relationship between communication overload and job satisfaction; and (c) a moderating effect of communication overload on the relationship between low synchronous channels and organizational identification.     

Secondary school students’ perceptions of working life skills in science-related careers

ABSTRACT

School students demonstrate a lack of interest in choosing science studies and science-related careers. To better understand the underlying reasons, this study aims to examine secondary school students’ perceptions of working life skills and how these perceptions relate to the skills of the twenty-first century. The participants in this study were 144 Finnish 7th graders (aged 13–14 years). Using a questionnaire and qualitative content analysis, we examined their perceptions of working life skills in ‘careers in science’ and ‘careers with science’. Results reveal that although students have a great deal of knowledge about working life skills, it is often just stereotyped. Sector-specific knowledge and skills were highlighted in particular but skills related to society, organisation, time and higher order thinking, were often omitted. Results also indicate that students do not associate ‘careers in science’ with creativity, innovation, collaboration or technology and ICT skills. Conversely, according to the students, these careers demand more sector-specific knowledge and responsibility than ‘careers with science’. We conclude that students need more wide-ranging information about scientific careers and the competencies demanded; such information can be acquired by e.g. interacting with professionals and their real working life problems.     

Social and communicational skills in upper secondary vocational education and training

This article presents the methodology used by the Finnish Education Evaluation Council in the national evaluation of social and communication skills in vocational education and training. The evaluation concentrates on key competences such as learning-to-learn skills, communication skills, social skills and entrepreneurship （Implementation of Education and Stringfellow, 2005; Recommendation of the European Training 2010, 2004; Winterton, Delemare-Le Deist ＆ Parliament and of the Council of December 18, 2006 on key competencies for lifelong leaming, 2006）. The evaluation focuses particularly on skills required in the labour market. These competences are included in all vocational study programmes as a part of accompanying with other key competences. The authors＇ approach follows the principles of developmental and participative evaluation, applying the Common Quality Assurance Framework （CQAF） model, which has been accepted by the European Commission for the quality management and quality assurance framework for vocational education and training in Europe. Additional methods such as interview and statistical data gathering were used to acquire comprehensive data and ensure extensive participation of each partner involved has key competences. The evaluation material was collected from vocational education and training providers by sector （n=8） and by qualification （n=53）. Every sector and type of examination was included in the evaluation. The evaluation was based on a sample （n=130）. The evaluation data were collected from multiple sources by using multiple methods. The material included written self-evaluation reports by vocational education and training providers （n=130 which equals 95% of VET providers）, quantitative information, interviews organized by the National Board of Education and an evaluation seminar for providers as focus groups. Educational administrators, teachers, students, employers and workplace instructors participated in the self-evaluation of the vocational education and training establishments （multi-professional evaluation）.
