Published: October 2016

Objective: The aim of this study was to evaluate the frequency of tooth abnormalities in pediatric patients treated for central nervous system neoplasms. Material and methods: This cross-sectional study assessed thirty-one patients, median age 14.2 years (range 5 - 25), who were off therapy for at least one year, comparatively with a control group of thirty-one healthy patients matched for age with the study group. Tooth abnormalities were evaluated by panoramic radiographs. Results: There was no statistical significant evidence that patients of the study group (age range 5 - 25 years) have more frequency of tooth abnormalities comparatively with controls. However, in children who were diagnosed before 5 years of age, microdontia was the most common abnormality with statistically significant difference (P=0.037). Root shortening grade III was observed in patients over 10 years of age at the time of radiographic examination, also with statistical significance (P=0.046). Conclusions: Tooth abnormalities frequency in patients treated for central nervous system neoplasms is directly related to the age of diagnosis and stage of odontogenesis. Microdontia and reduced root surface areas, the most common abnormalities observed, can lead to future oral health impairment due to malocclusion and less periodontal support. It is important to give parents and patients early orientation about maintenance of good oral hygiene and proper treatment by orthodontics or dentofacial orthopedics.

Published: October 2016

Objective: The aim of this pilot study was to perform in vitro analysis of the stress related to instrumentation of artificial root canals with Reciproc System by using the photoelasticity method. Material and Methods: Photoelastic models consisted of two epoxy resin blocks simulating root canals, which were attached with cyanoacrylate adhesive to a base and placed at the centre of a circular polariscope in a dark-field configuration. The Reciproc R25 instrument was mounted to a VDW motor and used in block 1 up to 12 mm (working length) and then the same instrument was used in block 2. The images were captured by video camera and analysed at the time of the fourth penetration. Isochromatic fringes were observed in the cervical, middle and apical thirds at mesial and distal regions of each block. Therefore, they were divided into cervical-mesial (CM), cervical-distal (CD), middle-mesial (MM), middle-distal (MD), apical-mesial (AM) and apical-distal (AD). Results: In the first instrumentation, it was found that the greatest stress occurred at the middle-distal region (1.38), followed by middle-mesial (1.20), apical-distal (1.20) and apical-mesial regions (1.20). In the second instrumentation, the greatest stress occurred at the middle-mesial (1.20), apical-distal (1.20), apical-mesial (1.20) and middle-distal regions (0.90). Conclusion: The greatest stress occurred in the middle and apical thirds during the first instrumentation. Re-utilization caused less stress.

Soil enzymatic activity in artificially and naturally regenerated forests after wind damage in north-eastern Poland
Authors: Olszowska Grażyna 
Published: October 2016

Abstract.
The aim of the study was to describe biochemical reactions in the soil based on the activity of urease and dehydrogenases in Scots pine stands damaged during and differentially managed after hurricanes. Soil enzymatic activity was investigated in 2005 and again in 2013 for selected stands in the Pisz Forest District where wind damage occurred in 2002. Most of the damaged stands were cut down and replanted, but 445 ha were left untouched for study purposes. The investigated areas differed with respect to stand damage and management. The enzymatic activity correlated well with the content of organic matter which was higher in organic than in mineral soils. In the area left to regenerate naturally, dehydrogenase and urease activity was higher in 2013 compared to 2005, which suggests the improvement of site conditions. The values of the examined biochemical parameters were correlated with the type of forest regeneration, with the forest soil regeneration being higher in artificially than in naturally regenerated stands. Changes of soil enzymatic activity were correlated with the level of stand damage and the type of management after wind damage.
Evolving training modules for hearing impaired individuals for gainful
employment in garment manufacturing processes
Authors: Chaudhry Jyoti Bhasin 
Published: October 2016

Abstract
The present study was undertaken to create job opportunities for
hearing-impaired individuals in garment-manufacturing and sequin-finishing
units. Employment is not only a statistical and practical issue but also a
human rights and entitlement issue. The differently abled are no exception
to this basic right. Disability is no longer a welfare or charity issue.
However, unlike non-disabled people, people with disabilities, more often
than not, face difficulties in getting educated and in accessing vocational
training and higher education. Working with people with disabilities can be
challenging, but by providing them with work and recognition, it can be the
beginning of another way of life rather than the end of life for them. It is
important to identify their capabilities and accordingly find suitable jobs,
wherein with proper training along with encouragement, compassion, and
constant motivation, they can effectively adapt to and settle in specific
job operations. This study identifies various operations in different
sections of these units and explores the training possibilities there, in an
attempt to make the hearing impaired employable. Because of their limited
abilities, it requires additional efforts for them to compete in the open
labor market. Thus, this is an attempt to prove that hearing-impaired
individuals can be gainfully employed in open employment
situations.
Modeling social factors in language shift
Authors: Ravindranath Abtahian Maya , Cohn Abigail C. , Pepinsky Thomas 
Published: October 2016

AbstractThis article introduces a quantitative approach to modeling language shift in communities with millions of speakers. Using Indonesia as a case study, and employing a large body of data from the Indonesian population census, we document how factors such as urbanization, ethnicity, economic development, gender, and religion correlate with the shift from local languages (Javanese, Sundanese, etc.) to the national language, Bahasa Indonesia. Our findings inform ongoing research on the sociological foundations of language shift across both small and large communities. Methodologically, we introduce a statistical approach that borrows from other social sciences, and show how to exploit massive amounts of untapped linguistic, demographic, and sociological data.

Visual ‘Bildung’ between Iconoclasm and Idolatry
Authors: Fritze Yvonne , Haugsbakk Geir , Nordkvelle Yngve 
Published: October 2016

AbstractThe point of departure for this article is ‘the visual turn’, the proclaimed need for specific competencies, and furthermore the lack of clarity in the concepts and the lack of research that accompany the use of images. Terms like ‘visual literacy’ and “visual competence’ are compared with a concept of visual ‘Bildung’. ‘Bildung’ is presented as a concept that clearly goes beyond qualifications and a dominant market-oriented comprehension of competence. In its origin, ‘Bildung’ has obvious references to ‘image’, and it may also offer interesting new perspectives in the battle between words and images that has taken place throughout history and is a background to today’s situation. ‘Bildung’ opens up an interesting path between iconoclasm and idolatry. The article proclaims an urgent need for a visual and reflective ‘Bildung’, because images are closely related to the world in which we live today.
Surely, We’ll Need Backups
Authors: Silverman Randy 
Published: October 2016

Abstract
For 20 years the U. S. Newspaper and Brittle Books Programs focused national resources on a singular approach to preserving acidic paper in research libraries—converting printed “information” to microfilm. In many cases, the original historical material was discarded in the process. This method failed to address the root problem that could have been solved more effectively and more economically through preventive conservation. Such conservation was ignored because an ulterior motive to the brittle books “crisis” was to establish a national digital library. A serious consequence arising from this subterfuge is that today mid-sized research libraries are not committed to—and perhaps fail to comprehend the importance of—preserving their general collections. Collectively these diverse, paper-based collections represent a huge swath of the nation’s historical record. Falsely believing digital media will make paper obsolete, and motivated by a need to create space in libraries, today’s vigorous weeding for non-rare, paper-based general collections threatens to destroy evidence that will be required for research and future digitization projects. These materials will be needed as backups to accurately regenerate screen copies; as master copies to augment, enhance, or correct faulty screen copies; and, as authentication to verify original production techniques and determine provenance. Without careful coordination and item-level verification, today’s isolated weeding practices could eviscerate American general collections with devastating results for future scholarship, repeating the mistakes of the U. S. Newspaper and Brittle Books Programs.
Sport and Tourism Between Modernity and Postmodernity
Authors: Lenartowicz Michał , Isidori Emanuele , Maussier Barbara 
Published: October 2016

Abstract
The text presents and analyses manifestations of modernity and postmodernity in the field of competitive and recreational sport, physical education, leisure, and tourism. The paper builds upon an extensive literature survey and presents the concept and key features of postmodern societies and the modernity-postmodernity debate in sports with reference to postmodern tendencies in tourism. We have attempted to determine the proportions of tradition, modernity, and postmodernity in contemporary sport and tourism, keeping in mind that, similarly to contemporary societies as a whole, sport is undoubtedly a mixture of traditional, modern, and Fordist elements with postmodern and post-Fordist features. We present and discuss the prevailing belief that the key elements of leisure sport are mostly postmodern and focused on the notion of individualisation and freedom expressed especially in alternative sports, while commercialised mainstream sport follows the regular mass-media show-business development path, maintaining a significant amount of modern concepts, such as the importance of national identities. Special attention is also paid to the Olympic Games as a specific and very efficient mixture of modernity and postmodernity. More so than at any point in the past, and despite the actual proportions of modernity and postmodernity that it contains, contemporary sport has become an integral part of postmodern societies and their lifestyle, with technology-determined individualisation of sport consumption and leisure sport participation.
Impact of Regulation Change on Half-Court Offence in the Polish Basketball League
Authors: Gryko Karol , Słupczyński Bogusław , Kopiczko Anna 
Published: October 2016

Abstract
Introduction. Each change in the rules of a sport affects the way it is performed. Therefore, changes in regulations require that new training models be developed. The aim of the study was to determine whether FIBA’s introduction of new regulations in the 2010/2011 season pertaining to the dimensions of certain parts of the playing area, which changed the conditions under which the game was played, impacted the offensive actions of the top three teams in the Polish Basketball League. Material and methods. The study analysed qualitative data describing the offences (n = 16,694) performed during 200 matches of the Polish Basketball League, that is the highest-level men’s professional basketball league in Poland, during two periods: the 2009/2010 season (110 matches; n = 9,343 offences), before the regulations were modified, and the 2010/2011 season (90 matches; n = 7,351 offences), after they were changed. The research involved the players of three teams who received the gold, silver, and bronze medals in the final standings of the Polish National Championship in the 2009/2010 season. Results. The study found a statistically significant (p < 0.001) decrease in the overall number of tactical offensive actions of 3.84% and a significant (p < 0.05) 5% decrease in the mean number of points scored. A significant (p < 0.05) decrease in half-court offences, amounting to almost 2% was also observed. This offensive system was characterised by a minor shift toward individual offences with the back to the basket and pick-and-roll offences; these changes, however, did not cause an increase in the level of effectiveness. Conclusions. The direction of the changes observed have been determined, which consisted in a reduction in the overall number of offensive actions and a shift in the place where they were completed, from the three-point area in particular, to the two-point area.
A Transient EPR Study of Electron Transfer in Tetrathiafulvalene-Aluminum(III) Porphyrin-Anthraquinone Supramolecular Triads

Published: October 2016

Abstract
The stabilization of light-induced charge separation in two axially bound triads based on aluminum(III) porphyrin (AlPor) are investigated using the electron spin polarization patterns of the final radical pair state. In the triads, TTF-(Ph)n-py-AlPor-AQ, (n=0, 1) anthraquinone (AQ) is attached covalently to the Al(III) center, while the donor tetrathiafulvalene (TTF) coordinates to Al(III) on the opposite face of the porphyrin ring via the appended pyridine (py). The dyad AlPor-AQ has been studied previously (M. Kanematsu, P. Naumov, T. Kojima, S. Fukuzumi, Chem. Eur. J. 17 (2011) 12372.) and shown to undergo fast light-induced charge separation and triplet recombination. Here, it is shown that by coordinating pyridine-appended TTF to the porphyrin, the charge separation can be stabilized. The spin polarized transient EPR spectra of the state TTF·+AQ·− can be observed in both the glass phase and in liquid solution and show that the state is formed from a singlet precursor on a timescale of less than ~0.5 ns. Using structural models to fix the geometry of the radical pair and the strength of the dipolar coupling, it is possible to determine the sign and approximate magnitude of the exchange coupling between TTF·+ and AQ·−. In contrast, other similar triads, which display relatively large ferromagnetic coupling, the exchange coupling is found to be small and antiferromagnetic. This difference can be rationalized as a result of differences in the structure of the bridge between the porphyrin and the acceptor.

Published: October 2016

<p>O Imposto Territorial Rural (ITR) é um tributo de competência da União, e 50% de sua arrecadação deve ser transferido ao município de origem. Entretanto, existe a possibilidade de esse município apropriar-se de 100% da receita desde que assine um convênio com a Receita Federal e passe a ser o agente fiscalizador do tributo. Nesse sentido, na presente pesquisa teve-se por objetivo analisar a arrecadação do ITR nos municípios de Minas Gerais nos anos 2011 e 2012, fazendo uma comparação entre os municípios conveniados e os que não são. Além disso, buscou-se identificar os impactos na arrecadação após o município aderir ao convênio. Metodologicamente foram utilizados os testes de Mann Whitney e o teste T de Student para amostras emparelhadas. Os resultados indicaram que, de maneira geral, os municípios conveniados possuem arrecadação superior aos municípios não conveniados. Entretanto, ao se analisar a arrecadação dos municípios antes e depois de aderirem ao convênio, ficou constatado que mesmo aumentando a média de arrecadação essa diferença não foi estatisticamente significativa, uma vez que se verificam alguns municípios que diminuíram a arrecadação do ITR após aderirem ao convênio.</p><p>Palavras-chave:<strong> </strong>Imposto Territorial Rural.
