Learning as a Merged Phenomenon of the Learner and the Content to Be Learned  [PDF]
Mona Holmqvist Olander, Per Selin
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.710143
Abstract: This paper aims to contribute to knowledge of education based on a non-dualistic perspective on learning, by considering how a variation theoretical perspective seeing learning as a merged phenomenon of the learner and the object to be learnt affects instruction. In this project, teachers’ theoretical non-dualistic awareness was developed through the introduction of variation theory as a guiding principle during a school-based research project. Based on a non-dualistic epistemological standpoint, the analysis focuses on the characteristics of instruction and learning from an assumption that the learner and the content learned cannot be separated. The data used for the analysis is from an example of instruction on learning to communicate in a foreign language. The analysis aimed to answer the questions: How do teachers orientate learners, carry out teaching and consolidate learners’ knowledge? And how does this non-dualistic standpoint affect assessment? The results show in what way teachers transform and enact the curriculum objectives in teaching activities based on the learners’ perspectives, which in turn describes how they change their way of assessing the students’ learning in line with the theoretical assumptions by testing context-situated video-recorded group assessment, which are individually analysed.
Changes of Reef Community near Ku Lao Cham Islands (South China Sea) after Sangshen Typhoon  [PDF]
Yuri Ya. Latypov, Nikolai Selin
American Journal of Climate Change (AJCC) , 2012, DOI: 10.4236/ajcc.2012.11004
Abstract: Coral reefs of Ku Lao Cham Islands in the Central Vietnam were studied over a quarter of a century. It was established that the reefs of these Islands were lost after the Sangshen typhoon and a heavy flood, which happened in 2006. As a result of these natural phenomena a significant part of coral populations was physically destroyed, and a powerful export of clay substances from the nearest Vietnamese coast and from the Bung River, flowing into the sea opposite the Islands, causing abundant sedimentation and death of almost all the remaining scleractinian corals. At present, where formerly there were coral reefs, now there is algal-alcyonarian stage of succession of reef communities. This is typical, as a rule, for restoration of reefs after a destructive typhoon effect.
Implementation of substitution treatment in Finland: Beyond rationalisation and medicalisation
Jani Selin
Nordic Studies on Alcohol and Drugs , 2011, DOI: 10.2478/v10199-011-0003-6
Abstract: AIMS - Finnish treatment of drug abuse has during the last two decades shifted from a predominantly psychosocial approach to a more medical mode. This is especially evident in the rapid implementation of substitution treatments (STs). My aim is to show that labelling this development as ‘medicalisation’ or ‘rationalisation’ as a form of medical progress will not increase our understanding of the change. MATERIAL AND DESIGN - I analysed texts from several periodicals with psychosocial, social policy and medical perspectives between 1997 and 2005. Four basic conceptual and argumentative underpinnings emerged which gave credence to the medical and rational approach, and the validity of these four elements was then investigated. I also collected all the texts on drug addiction and its treatment from two medical journals in 1965-1976 to examine the way in which drug addiction was conceptualised during this earlier phase. RESULTS - The material shows that there are at least four reasons why medicalisation and rationalisation cannot explain the implementation of substitution treatments in Finland. First, progress in medical research on addiction did not make STs necessary. Second, the effectiveness of substitution treatments hinges on a particular kind of scientific rationality that cannot be equated with rationality per se. Third, it was not the 1990s and 2000s that drug addiction was coded as a medical problem for the first time. Fourth, it is difficult to include into the medicalisation theory how people actively want to be ‘medicalised’. Medical knowledge and technology open up new domains of knowledge with possible relations to practices of power and offer people new ways of self-understanding. How these different practices work is a question of empirical research. Both ‘rationalisation’ and ‘medicalisation’ are concepts often used in an inflationary way, and this may make them insensitive as analytical instruments.

Abstract: The article is based on two data corpora. The first corpus is the so called "Porubezhnye (Borderline) Acts" which is a part of the 17th century Novgorod Ambassador Court Archives held in the Archives of St. Petersburg Branch of the Institute of Russian History. The second corpus is a part of Kammararkivet, named Baltiska Fogder kenskaper, and consists of the economic acts and deeds made in Ivangorod, Iam, Koporie, Oreshek (Noteburg), Nevsky Ostrozhek (Nyen), Gdov and on the territories ascribed to the fortresses in 1580-1589 and 1612-1618. During the Novgorod-Swedish administration 1611-1617 these relations were pliable (there were even parleys about a possible contact between the two Churches), but after the Stolbovo Treaty 1617 interrelations between the churches had become deteriorating. The Swedish government tried to control the Orthodox clergy in the annexed districts, while the Moscow state attempted to leave it under the control of the archbishop of Novgorod. In the mid-17th century new factors in the everyday life in the Russian-Swedish border region revealed. A new wave of Orthodox migrants from Ingermanland and the Kexholm district in Sweden arrived at the Moscow State and at the same time patriarch Nikon's church reform was held. This circumstance has partly shaped the general attitudes towards the migrants: traditionally they were perceived as schismatics. The most important factor was the language barrier between the migrants, Izhorians and Karelians, and the autochthonous Russian population in the borderline area and the inside territories where the migrants had settled (the so called Tver' Karelia). To sum up, the transition of some Novgorod Orthodox districts to the Lutheran State had created a principally new precedent. As known, the concepts of confession and citizenship were practically identical in the 16th -17th century popular thought, when Orthodoxy automatically meant Moscow citizenship. The transition of a number of Orthodox parishioners to foreign citizenship had significantly troubled both the Moscow Governors and the clergy, and had created an atmosphere of uncertainty, where nobody knew who factually had the right to appoint priests, etc. The possible way out was to appoint a local bishop for the Orthodox parishes in Ingermanland but that, of course, was impossible for the Moscow governors. The result was a paradoxical situation where the church ruling, justice, and administration of the Orthodox parishes were handed over to probsts - special officials appointed by the Swedish Lutheran government.
Computationally Efficient Scale Covariant Time-Frequency Distributions
Selin Aviyente
EURASIP Journal on Advances in Signal Processing , 2009, DOI: 10.1155/2009/204351
Abstract: Scale is a physical attribute of a signal which occurs in many natural settings. Time-frequency distributions (TFDs) belonging to Cohen's class are invariant to time and frequency shifts, but are not necessarily covariant to the time scalings of the signal. Conditions on the time-frequency kernel for yielding a scale covariant distribution have been previously derived (Cohen, 1995). In this paper, a new class of computationally efficient scale covariant distributions is introduced. These distributions are constructed using the eigendecomposition of time-frequency kernels (Burrus et al., 1997). The performance of this new class of distributions is illustrated with examples and is compared to conventional scale covariant distributions.
Quantification of Effective Connectivity in the Brain Using a Measure of Directed Information
Ying Liu,Selin Aviyente
Computational and Mathematical Methods in Medicine , 2012, DOI: 10.1155/2012/635103
Abstract: Effective connectivity refers to the influence one neural system exerts on another and corresponds to the parameter of a model that tries to explain the observed dependencies. In this sense, effective connectivity corresponds to the intuitive notion of coupling or directed causal influence. Traditional measures to quantify the effective connectivity include model-based methods, such as dynamic causal modeling (DCM), Granger causality (GC), and information-theoretic methods. Directed information (DI) has been a recently proposed information-theoretic measure that captures the causality between two time series. Compared to traditional causality detection methods based on linear models, directed information is a model-free measure and can detect both linear and nonlinear causality relationships. However, the effectiveness of using DI for capturing the causality in different models and neurophysiological data has not been thoroughly illustrated to date. In addition, the advantage of DI compared to model-based measures, especially those used to implement Granger causality, has not been fully investigated. In this paper, we address these issues by evaluating the performance of directed information on both simulated data sets and electroencephalogram (EEG) data to illustrate its effectiveness for quantifying the effective connectivity in the brain.
Density-Dependent Habitat Selection in a Growing Threespine Stickleback Population
Ulrika Candolin,Marita Selin
International Journal of Zoology , 2012, DOI: 10.1155/2012/378913
Abstract: Human-induced eutrophication has increased offspring production in a population of threespine stickleback Gasterosteus aculeatus in the Baltic Sea. Here, we experimentally investigated the effects of an increased density of juveniles on behaviours that influence survival and dispersal, and, hence, population growth—habitat choice, risk taking, and foraging rate. Juveniles were allowed to choose between two habitats that differed in structural complexity, in the absence and presence of predators and conspecific juveniles. In the absence of predators or conspecifics, juveniles preferred the more complex habitat. The preference was further enhanced in the presence of a natural predator, a perch Perca fluviatilis (behind a transparent Plexiglas wall). However, an increased density of conspecifics relaxed the predator-enhanced preference for the complex habitat and increased the use of the open, more predator-exposed habitat. Foraging rate was reduced under increased perceived predation risk. These results suggest that density-dependent behaviours can cause individuals to choose suboptimal habitats where predation risk is high and foraging rate low. This could contribute to the regulation of population growth in eutrophicated areas where offspring production is high. 1. Introduction Individuals are usually forced to balance costs against benefits when choosing a habitat [1, 2]. Structurally complex habitats are often more favourable than open habitats, as they provide more resources and better refuges against predators [3–5]. However, complex habitats can also be costly if they harbour more predators and competitors than open habitats [6, 7]. In addition, the costs and benefits of choosing a habitat depend on what other individuals in the population are doing [8–10]. The profitability of a habitat decreases the more individuals that occupy it, because of a reduction in the amount of resources available per individual. As high quality habitats become saturated, more and more individuals are forced to occupy poor-quality habitats [11, 12]. Interactions among individuals will then influence habitat selection, and, thus, density-dependent processes will affect individual fitness and the temporal and spatial distribution of the population. Human activities are currently altering habitats at an unprecedented rate and scale around the world. The consequences that this will have for the populations that were well adapted to the past conditions are poorly known. An environment that is changing rapidly because of human activities is the Baltic Sea. Increased input of
Ekonomska upravi enost uporabe metod digitalne forenzike (Economic Justification of Use of Digital Forensic Methods)
Liljana Selin?ek
LeXonomica : Journal of Law and Economics , 2009,
Abstract: The author is trying to connect the field of law and economics with the usage of digital forensic methods that are increasingly important evidence means in modern information society for proving of different criminal offences’ elements as well as other important facts in legal proceedings. The basis of the article is the (hypo)thesis that digital forensic methods are proper evidence means only in cases where expected benefit from evidences collected with this methods is higher than the costs of digital forensic investigation. The author is pointing out also the fact that economic views of digital forensics are of complex nature because they interfere with the battle between commercial and open source tools for digital forensic investigations where many interests collide: those of technological companies that develop forensic software, of police, jurisdiction and consumers.

Extended Class of Pruned Crossbar Switches for Optical Networks
Hitoshi Obara,Pavel Selin
International Journal of Electronics Communication and Computer Technology , 2013,
Abstract: Reducing crosspoints of conventional pruned crossbar switches (PXBSs) with N2 3 crosspoints, where N is the switch size, was investigated from an architectural point of view. PXBSs have been created by removing parts of 2x2 switching elements (or simply cells) from crossbar switches (XBSs), while preserving both the switches’ planar structure and wide-sense nonblocking property. In this paper, we consider an extended class of PXBSs that has either a 3D structure or rearrangeably nonblocking capability. Two new families of extended PXBSs are described. The first is wide-sense nonblocking; it has a 3D structure of N(N 1) cells. Its form is similar to those of ILLIAC(N, N 1) torus networks and is isomorphic to a degree-four chordal ring. Its switch control complexity becomes O(1) like conventional XBSs. The second has nearly 3N2/4 cells in a planar structure; it is rearrangeably nonblocking and its switch control complexity is O(N). Its maximum number of rearrangements remains three, regardless of N for N 5. It decreases to two, if a pair of input and output ports is left unused. We point out that the second switch provides a missing link between crossbar switches of N2 cells and triangular switches of N(N 1)/2 cells and yields different rearrangeably nonblocking switches, with the number of rearrangements ranging from three to N 2.
