    One-time treatment for incidental vocabulary learning: Call for discontinuation

    Get PDF
    Incidental vocabulary learning has attracted a great deal of attention in ELT research. However, it is important that teacher and researcher exploitation of vocabulary developments be guided by more than replication of previous research designs. For conclusions based on empirical research to be valid, it is important to be clear about exactly what any data being gathered pertains to. While Karakas & Saricoban (2012) claim to have presented a solid piece of research on the effects of subtitled cartoons on incidental vocabulary learning, in practice it is not so. It is argued that the research design validity resulted in questionable results having little relevance to genuine incidental vocabulary learning

    Bible Localization and the Politics of Memory and Oblivion

    Get PDF
    For centuries the Bible and its teaching have been used to construct identities in the Western world. Today the range of ‘legitimate’ identities is much larger than several decades ago. Facing issues of ethnicity, religion, gender-role identity and sexual orientation, people are confronted with restated contemporary questions of ‘Who am I? and ‘What is the meaning of my life?’ These questions are often hard to answer and many people struggle with them throughout their whole lives. What we are witnessing today is an extreme case of what the author calls ‘groupcentric Bible translation’ or ‘Bible localization’, also referred to as ‘niche Bibles’. Groupcentric translation is a logical continuation of ethnocentric translation that distorts the other culture to suit the views of a new audience. Another way to describe this phenomenon is to use the term ‘localization’ taken from the software industry that describes any changes required to adapt a product to the needs of a particular ‘locale’, i.e. a group of people united by their common language and cultural conventions

    A System for Assessing the Knowledge and Skills of Students in Computer Programming

    Get PDF
    This article presents the author’s experience in teaching programming to university students in first and second year. The system for assessing the knowledge and skills of students is an essential part of teaching. It aims not only to assess students, but also to help improving their knowledge. The importance and difficulty of Computer Programming requires specific and unconventional approach to this activity. The article discusses all three elements of ongoing assessment (tests for knowledge, homeworks, and practical programming skills), as well as the rules for final exams and final assessment

    Phenol Biodegradation by Two Xenobiotics-Tolerant Bacteria Immobilized in Polyethylene Oxide Cryogels

    Biofilms were formed on poly(ethylene oxide) (PEO) cryogels by using bacteria cultured from xenobiotics polluted environments and their phenol biodegrading capability was studied. PEO cryogels were synthesized via UV irradiation cross linking of moderately frozen aqueous system. Two xenobiotics tolerant bacterial isolates KCM R5 and KCM RG5 were used to construct the biofilms on the cryogels. Obtained PEO-biofilms were assessed for their ability to remove phenol at concentrations 300, 400, 600 and 1000 mg L-1 for 28 days. The biofilm PEO-KCM RG5 removed phenol up to 600mg L-1/24 h, whereas the biofilm PEO-KCM R5 was able to degrade up to 1000 mg L-1/24 h. The high content of free-water in the cryogels allowed reproduction of the used bacteria. The high content of free-water in the cryogels allowed reproduction of the used bacteria. Short initial adaptation of the PEO-bio�lms with 100 mg L-1/24 h phenol was crucial for protecting the bacterial cells from dead. The obtained results showed that the liquid debit through the bio�lms on the 28th day of the experiments was lower than at the beginning. The cryogels demonstrated non-toxicity, high biocompatibility with bacteria and excellent mechanical characteristics. After aggressive phenol treatment the PEO-biofilms remained compact, porous and elastic. The investigated new biological materials demonstrate potential for application in the industrial wastewater treatment technologies

    Sustainable Efficiency and Usability for E-Learning Systems: Practical guide

    Get PDF
    This Guide has been written as a continuation of the efforts made during the SF-HEAT project to apply usability best practices in the design and development of the e-learning system of the project. The main idea that underlies the methodology behind the Guide is that educational effectiveness and efficiency crucially depends on the usability of the e-learning system. The Guide focuses on a simple practical approach related to a modified ADDIE model for sustainable usability improvement of the e-learning system

    Xenobiotic biotransformation potential of Pseudomonas rhodesiae KCM-R5 and Bacillus subtilis KCM-RG5, tolerant to heavy metals and phenol derivatives

    Get PDF
    Two environmental bacterial isolates KCM-R5 and KCM-RG5 were selected from xenobiotic-polluted environment. KCM-R5 was identified as Pseudomonas rhodesiae and KCM-RG5 as Bacillus subtilis. KCM-R5 demonstrated tolerance to heavy metals and KCM-RG5 to heavy metals and phenol derivatives. Both strains were studied for xenobiotic biotransformation in order to contribute towards bioremediation of polluted environments. Pseudomonas rhodesiae KCM-R5 and Bacillus subtilis. KCM-RG5 possess unusual ability to utilize ortho-nitrophenol (o-NP) and 2,4- dichlorophenoxyacetic acid (2,4-D). o-NP and 2,4-D were added at concentration 30 mg/l. The possible indictive/inhibiting effect of Pb cations (40mg/l) was also studied. Pseudomonas rhodesiae KCM-R5 removed 86 % of o-NP and below 1% of 2,4-D. Bacillus subtilis KCM-RG5 eliminated 83% of o-NP andunder 1% of 2,4-D. Biotransformation effectiveness of o-NP reached 95-100% in contrast to 2,4-D where the effectiveness was just 15-20%. Cell morphological changes were registered during the biotransformation processes. The obtained results could contribute to manage bioremediation processes in polluted with heavy metals and phenol derivatives environments. . 1, . 2, . 2, .

    Reinforcing Students’ Research Abilities via Digital Repositories

    Computer science graduates are requested to possess complex professional abilities including research skills. In this paper we justify the development of a departmental repository to assist all non-auditorium activities and summarize its benefits. We are convinced that this is the way students and teachers to form interim learning societies
