Compact spatio-spectral algorithm for single image super-resolution in hyperspectral imaging
Authors: Marquez Castellanos Miguel Angel , Vargas Cesar Augusto , Arguello Henry 
Published: December 2016

Hyperspectral imaging (HSI) is used in a wide range of applications such as remote sensing, space imagery, mineral detection, and exploration. Unfortunately, it is difficult to acquire hyperspectral images with high spatial and spectral resolution due to instrument limitations. The super-resolution techniques are used to reconstruct low-resolution hyperspectral images. However, traditional superresolution (SR) approaches do not allow direct use of both spatial and spectral information, which is a decisive for an optimal reconstruction. This paper proposes a single image SR algorithm for HSI. The algorithm uses the fact that the spatial and spectral information can be integrated to make an accurate estimate of the high-resolution HSI. To achieve this, two types of spatio- pectral downsampling, and a three-dimensional interpolation are proposed in order to increase coherence between the spatial and spectral information. The resulting reconstructions using the proposed method are up to 2 dB better than traditional SR approaches.
Investigating the influence of infill percentage on the mechanical properties of fused deposition modelled ABS parts
Authors: Álvarez Kenny , Lagos Rodrigo F. , Aizpun Miguel 
Published: December 2016

3D printing is a manufacturing process that is usually used for modeling and prototyping. One of the most popular printing techniques is fused deposition modeling (FDM), which is based on adding melted material layer by layer. Although FDM has several advantages with respect to other manufacturing materials, there are several problems that have to be faced. When setting the printing options, several parameters have to be taken into account, such as temperature, speed, infill percentage, etc. Selecting these parameters is often a great challenge for the user, and is generally solved by experience without considering the influence of variations in the parameters on the mechanical properties of the printed parts.This article analyzes the influence of the infill percentage on the mechanical properties of ABS (Acrylonitrile Butadiene Styrene) printed parts. In order to characterize this influence, test specimens for tensile strength and Charpy tests were printed with a Makerbot Replicator 2X printer, in which the infill percentage was varied but the rest of the printing parameters were kept constant. Three different results were analyzed for these tests: tensile strength, impact resistance, and effective printing time. Results showed that the maximum tensile force (1438N) and tensile stress (34,57MPa) were obtained by using 100% infill. The maximum impact resistance, 1,55J, was also obtained with 100% infill. In terms of effective printing time, results showed that printing with an infill range between 50% and 98% is not recommended, since the effective printing time is higher than with a 100% infill and the tensile strength and impact resistance are smaller. In addition, in comparing the results of our analysis with results from other authors, it can be concluded that the printer type and plastic roll significantly influence the mechanical properties of ABS parts.

THE DISTRIBUTION AND EVOLUTION OF INDICATORS OF HOSPITAL MORBIDITY AND MORTALITY FOR THYROID CANCER IN BRAZIL
Authors: Sales Danielle Freitas , Feitosa Caroline Alves 
Published: December 2016

INTRODUCTION: Thyroid cancer is the most common endocrine neoplasm, representing approximately 1% of all malignant tumors in western countries. It is three times more common in women than in men. AIMS: To analyze the changes in the rates of hospital morbidity and mortality from thyroid cancer in Brazil during the period from 2000 to 2012. MATERIAL AND METHODS: This is an ecological study, with data from the Brazilian Health Information Systems. Data regarding hospital morbidity and mortality from thyroid cancer (CID 10 C73) were collected as well as variables such as schooling, ethnicity and age group. RESULTS: This study identified 39,191 hospitalizations for thyroid cancer and 6,914 deaths from the same cause in the period investigated, with the occurrence and deaths much higher in women. Furthermore, the number of cases is also greater in subjects with incomplete basic schooling, and among individuals aged between 40-49 years. DISCUSSION: The findings are supported by other studies, although some of the characteristics of the patients have never been evaluated previously. CONCLUSION: Over the 13 year period assessed, there was an increase in the rates of hospital morbidity and mortality from thyroid cancer for both men and women in Brazil. More research on this subject is needed as well as health policies to increase awareness of the population about thyroid cancer and improve access to health services.

Legitimering gjennom (selektiv) felles fortid: russisk bruk av historie i Ukraina-konflikten
Authors: Holm Minda 
Published: December 2016

Abstract: Legitimation Through a (Selective) Shared Past: Russia’s Use of History in the Conflict in Ukraine
How has Russia used history to justify its actions in the conflict in Ukraine? Through an analysis of official statements of the Ministry of Foreign Affairs, as well as speeches and remarks by Putin, this article argues that history has played an important but varying role in official rhetoric. With Crimea, the emphasis was on the ‘sanctity’ of the territory for Russian Orthodox identity, drawing on history dating back to the baptism of Prince Vladimir in 10th century AC. The shared past of the two states has not been as central in official Russian policy justification regarding Ukraine outside Crimea: the ‘brotherhood’ of the two nations has been noted repeatedly, but usually secondary to arguments pertaining to economic and political interests. The two world wars have been used as a cautionary tale, with Russia effectively seeking to delegitimize the new Ukrainian government by evoking carefully selected elements of its past. Finally, the author looks at the use of international precedence as a form of justification, turning the history of Western – US in particular – actions back on Russia’s critics. The official usage of history is placed within broader strategies of legitimation, as it is not enough to study propaganda and manipulation strategies as part of information warfare to explain how the Kremlin achieves support for its policies. The ‘thick’ historical narratives of Crimea play on elements linked to issues of national identity, making it difficult to dispute using the type of counter-propaganda and rebuttal of disinformation proposed by some.

Limberg flap for pilonidal sinus: an institutional study
Authors: Mulla Sameer Ahmed , Pai Srinivas , Mahalingashetty Prakash 
Published: December 2016

Background: Pilonidal sinus disease is a common disorder affecting the gluteal cleft and it is notoriously recurrent. Limberg flap is a well-known surgical modality for the treatment of pilonidal sinus. This study aims at studying the surgery in a single institution.Methods: This is a prospective study of 17 limberg flaps done from 2013 to 2016. The various demographic, clinical and surgical data are studied and compared to other studies.Results: In this study, 17 patients of sacrococcygeal pilonidal disease underwent rhomboid excision and limberg flap reconstruction. The mean duration of symptoms was 6.52 months (2-13 months), and the mean operative time was 67.05 min with a range from 60 to 90 min. The mean post-operative stay was 6.05 days (3 to 10 days).Conclusions: Recurrence is known and hence surgery with flap coverage not only decreases the recurrence rates, but it also makes the stay short by eliminating daily dressing. Limberg flap is an easy and efficient way with less and manageable complication.
The Development of Multicultural Discourse in the Historical Learning: A Case Study on Samudra University Langsa Aceh
Authors: Akob Bachtiar 
Published: December 2016

The research analyzed the efforts conducted in the domain of historical learning in a university, especially related to how the past memory influences the recent multicultural discourses. The method used in this research is qualitative descriptive analysis with case study approach. The research was divided into three parts: (1) collecting data, (2) analyzing data, and (3) reporting the results of the research. Subjects of the research were selected by using purposive sampling technique; they were the 4th semester students up to the 6th semester students of the History Education Department in Samudra University Langsa Aceh. The research resulted findings that conceptually the students had understood about the concept of multicultural. Nevertheless, multicultural discourse had not touched the context of locality. Historical learning was designed to develop and expand the students’ multicultural discourse. The design of historical learning contains the learning strategy of ENACT, consisting of six stages: apperception, exploration, narrowing, analyzing, creating and teaching. Historical learning forms the students’ multiculturalism discourse, built from a historical understanding and the dynamics of Acehnese society. The students viewed that multicultural is a social condition, formed from historical process. Conflict understood by students as the dynamics which is inseparable from a multicultural society. However, the students considered that conflict caused many endless problems, therefore, the students’ multicultural discourse tended to lead to peace condition. Keywords: Historical Learning, ENACT, Multicultural.
Towards Careful Practices for Automated Linguistic Analysis of Group Learning
Authors: Howley Iris K , Rose Carolyn Penstein 
Published: December 2016

This paper reviews work in progress towards bridging the field of linguistics and its operationalizations of discourse, and that of frameworks for studying collaborative learning that are rooted directly in the learning sciences. We begin with the vision of a multi-dimensional coding and counting analysis approach that might serve as a boundary object between the variety of methodological approaches to analysis of collaborative learning that exist within the Learning Sciences. We outline what we have discovered from a combination of hand coding, comparison with alternative analytic approaches including network analytic and qualitative approaches, correlational analyses in connection with learning-relevant extralinguistic variables, and computational modeling. We explore both the contribution of work to date as well as the many remaining challenges.
Constraint-Referenced Analytics of Algebra Learning
Authors: Sutherland Scot McRobert , White Tobin F 
Published: December 2016

The development of the constraint-referenced analytics tool for monitoring algebra learning activities presented here came from the desire to firstly, take a more quantitative look at student responses in collaborative algebra activities, and secondly, to situate those activities in a more traditional introductory algebra setting focusing on procedural understanding. Procedural skill was analyzed by modeling the complexity of attempts to make equivalent transformations of algebraic expressions. The constraint-referenced analytics system uses log files of student inputs on a classroom network of handheld devices to measure success rate as students make attempts to replace one algebraic expression with another equivalent expression. The analytics engine produced psychometrically verifiable results. Moving averages of student performance revealed that when students experienced a period of struggle and persisted in attempting similar transformations, an apparent conceptual shift led to subsequent success. Students also responded to periods of struggle by switching to familiar tasks or choosing non-participation.

Irrelevant, Irrelevant, Irrelevant! Time to change our approach to research?

<p><span>To be able to practice evidence-based veterinary medicine, clinicians need high quality </span><em>relevant</em><span> evidence to integrate with their clinical decision making. Relevance is possibly more important than quality as even the best evidence cannot be used if it can't be applied to veterinary practice.</span><br /><br /><span>Research waste that refers to research that is undertaken where the results do not influence practice. It has been suggested that over 80% of research is wasted but is currently unknown how widespread this phenomenon is in veterinary medicine. Research waste occurs when research addresses the wrong question, it is poorly designed, executed or reported or not reported at all. </span><br /><br /><span>If the research question doesn't include the correct population of interest e.g. First opinion rather than referral caseload, animals with or without co-morbidities, then applying the results to practice will be impossible. The same is true if the interventions, tests and outcomes. One way of ensuring the research question is relevant to the end user is to involve stakeholders in prioritising and planning research. It has been shown by a number of researchers that poor study design and execution occurs frequently in veterinary research. The inadequacies in our evidence base can vary from the selection of inappropriate study design for the question posed through to the selection of inappropriate outcome measures. Poor reporting is also a feature of a large proportion of veterinary research which can hinder the use of the research findings. Even if research is reported well, unless it is open access the key people who could use the results may not be able to read it.
