Evaluating stance-annotated sentences from the Brexit Blog Corpus: A quantitative linguistic analysis
Authors: Simaki Vasiliki , Paradis Carita , Kerren Andreas
Published: April 2018

This paper offers a formally driven quantitative analysis of stance-annotated sentences in the Brexit Blog Corpus (BBC). Our goal is to identify features that determine the formal profiles of six stance categories (contrariety, hypotheticality, necessity, prediction, source of knowledgeanduncertainty) in a subset of the BBC. The study has two parts: firstly, it examines a large number of formal linguistic features, such as punctuation, words and grammatical categories that occur in the sentences in order to describe the specific characteristics of each category, and secondly, it compares characteristics in the entire data set in order to determine stance similarities in the data set. We show that among the six stance categories in the corpus,contrarietyandnecessityare the most discriminative ones, with the former using longer sentences, more conjunctions, more repetitions and shorter forms than the sentences expressing other stances.necessityhas longer lexical forms but shorter sentences, which are syntactically more complex. We show that stance in our data set is expressed in sentences with around 21 words per sentence. The sentences consist mainly of alphabetical characters forming a varied vocabulary without special forms, such as digits or special characters.

Published: April 2018

Increasing degrees of automation in on-road vehicles bear great potential for heightened driver safety and traffic efficiency in both the near and far future. The more the driver delegates control to the vehicle, the more salient the issue of trust in automated technology becomes. Misaligned trust can lead to mishandling of automation controls in individual instances and decreases the general acceptance of on-road automation on a broader scale. In this paper, we apply insights from trust research for dynamic web service interaction to the novel automated driving domain, in order to scope the problem space regarding trust in automated vehicles. We conclude that the appropriate communication of trustworthiness, the necessity to calibrate trust, the importance of intervention capabilities by the driver, and the unambiguous transparency of locus of control are all important aspects when in comes to understanding trust in automated vehicles.
Foot Interaction Concepts to Support Radiological Interventions
Authors: Hatscher Benjamin , Luz Maria , Hansen Christian
Published: April 2018

During neuroradiological interventions, physicians need to interact with medical image data, which cannot be done while the hands are occupied. We propose foot input concepts with one degree of freedom, which matches a common interaction task in the operating room. We conducted a study to compare our concepts in regards to task completion time, subjective workload and user experience. Relative input performed significantly better than absolute or rate-based input. Our findings may enable more effective computer interactions in the operating room and similar domains where the hands are not available.
Generating Structured Data by Nontechnical Experts in Research Settings
Authors: Breitenfeld Andre , Berger Florian , Hong Ming-Tung , Mackeprang Maximilian , Müller-Birn Claudia
Published: April 2018

Semantic technologies provide meaning to information resources in the form of machine-accessible structured data. Research over the past two decades has commonly focused on tools and interfaces for technical experts, leading to various usability problems regarding users unfamiliar with the underlying technologies – so-called nontechnical experts. Existing approaches to semantic technologies consider mostly consumers of structured data and leave out the creation perspective. In this work, we focus on the usability of creating structured data from textual resources, especially the creation of relations between entities. The research was conducted in collaboration with scholars from the humanities. We review existing research on the usability of semantic technologies and the state of the art of annotation tools to identify shortcomings. Subsequently we use the knowledge gained to propose a new interaction design for the creation of relations between entities to create structured data in the subject-predicate-object form. We implemented our interaction design and conducted a user study which showed that the proposal performed well, making it a contribution to enhance the overall usability in this field. However, this research provides an example of how technically sophisticated technology needs to be “translated” to make it usable for nontechnical experts. We need to extend this perspective in the future by providing more insight into the internal functioning of semantic technologies.
Multiscreen Patterns – Interactions Across the Borders of Devices
Authors: Madden Dominick , Schneider Horst , Kohler Kirstin
Published: April 2018

Design patterns are solutions for common design problems used in a number of fields including architecture, software development and user experience design. We compiled a pattern library for the usage of gesture-enabled interactions between different devices with screens, the so called multiscreen context. This library provides simple and intuitive gestures for connecting and disconnecting devices wirelessly as well as gestures for the exchange of data between these devices, like swiping a document from one’s tablet to the tablets of the surrounding colleagues in the same room. The library is the result of a 2.5 years running project in cooperation with three small and medium companies. We compiled the library by conducting an intense literature survey in parallel with several iterations of practical software projects in the multiscreen context. The literature survey inspired the practice-oriented project work. Being involved in software projects enabled us to identify challenges in the design and implementation of the gesture set. Therefore, we generated valuable insight for a comprehensive description of gestural interactions.

With our set of patterns, we aim to support interaction designers to choose the appropriate gesture for their given context. The patterns serve as inspiration by showing the different possibilities but also provide guidance how to design and implement a selected gesture for a given context. They help designing the details of an interaction by breaking it down into its smallest parts. To support the developers of these interactions our pattern descriptions are enriched with an Android library containing lifecycle events and the necessary gesture recognition logic. This paper provides an overview of the pattern library. In addition, the structure and the usage of the library is described in more detail with the means of one sample pattern. The pattern library is openly accessible.
Removal of Bisphenol-A from Aqueous Solutions by Pseudomonas aeruginosa in Batch Reactors: Effect of Carbon Source, Temperature and Concentrations
Authors: Keskinkan Olcayto , Balci Behzat
Published: April 2018

This study was carried out to investigate the potential ofPseudomonas aeruginosafor the removal of bisphenol-A (BPA) from synthetic wastewater. To achieve this, BPA removal capability ofP. aeruginosawith respect to BPA concentration, and temperature were examined in batch reactors. Experiments were conducted in the presence/absence of glucose, as a carbon source. The first set of experiments consisted of evaluating the kinetic of removal of BPA at different concentrations (5, 10, 20, and 30 mg BPA/L) without glucose. In the second set of experiments, three different glucose concentrations (0.5, 1.0, and 2.0 glucose/L) with BPA concentrations were tested. After settlement of theP. aeruginosabiomass in the shakers, supernatants and control groups were filtered and analyzed for BPA using high performance liquid chromatography. In the biotic study, BPA removal rates were between 63 % and 100 %. All concentrations of BPA under 20 mg/L were completely degraded at 25 and 35 ºC at first step. However, 30 mgBPA/L was decreased to 8.56 mg/L byP. aeruginosaat first step at 25 ºC. At the second step, all concentrations of BPA were completely degraded by the cells at the presence of glucose. Hence, it can be summarized that bisphenol A can be used byP. aeruginosaas an external carbon source in the wastewater environments.

Authors: De Greef J. , Verbinnen B. , Van Caneghem J.
Published: April 2018

Municipal Solid Waste Incineration (MSWI) has become the most widespread Best Available Technology (BAT) to treat residual waste streams in a reliable and safe way. As such, MSWI has contributed to achieve the landfill diversion targets in many EU member states. Modern waste incinerators, also referred to as Waste-to-Energy (WtE) plants, have furthermore evolved to producers of electricity, heat and steam for energy-consuming industries, agriculture and residences. However, due to the specific composition and properties of MSW and similar waste, and due to the historical development of MSWI, the exploitation of WtE plants as combined heat and power (CHP) plants is not straightforward. The aims of this paper are to develop a better understanding of these limitations, to point out possibilities for increasing the level of energy recovery and utilization in WtE plants, and to document this approach with data and experiences from selected WtE plants currently integrated in CHP schemes. Finally, some design and operational challenges for waste-fired CHP plants are further elaborated from a WtE plant supplier’s perspective.

Published: April 2018

In this study, the quality of matured coconut water was improved through fermentation with Saccharomyces cerevisiae D254. During fermentation, the kinetic models of yeast growth, alcohol production, and sugar consumption were established based on logistic and Leudeking–Piret equations. Fructose, glucose, sucrose, total phenolic content, and antioxidant capacity (FRAP and ABTS values) were measured consecutively during fermentation. Results showed that R
2 for the three models of yeast growth, alcohol production, and sugar consumption were 0.9772, 0.9983, and 0.9887, respectively. Total phenolic and antioxidant assays showed a similar evolution during fermentation, with a rapid increase in exponential phase and an unchanged trend in stationary phase. Moreover, total phenolic and the two antioxidant capacity methods were highly positively correlated. Pyruvic, lactic, citric, and succinic acids were the main organic acids in coconut water after fermentation.

Authors: Zielinska Magdalena , Michalska Anna
Published: April 2018

The effect of hot air convective drying (HACD), microwave-vacuum drying (MWVD) and combined drying (HACD + MWVD) on the drying kinetics, bioactive compounds and color of blueberry pomace was evaluated. Drying time of blueberry pomace ranged from 0.6 to 6.7 h and moisture diffusion coefficients ranged from 7.94 × 10–8 to 1.83 × 10–7 m2/s. Drying caused degradation of total polyphenolics (TP) (39–76%), monomeric anthocyanins (21–77%) and antioxidant capacity values (24–76%). Drying time was shortened even by 91%, when MWVD was used instead of HACD. MWVD of blueberry pomace resulted in the smallest, while HACD at 60°C in the greatest loss of bioactive compounds and antioxidant capacity. HACD at 60°C + MWVD allowed to obtain a product with a higher content of TP, monomeric anthocyanins and a stronger antioxidant capacity than HACD at 90°C + MWVD. Combination of HACD at 60°C with MWVD allowed for the shortening of HACD time by 75% as well as for hapering the chemical changes as compared to HACD at 60°C. Even when the combination of HACD at 90°C with MWVD shortened the drying time by 68%, it did not improve the retention of TP, monomeric anthocyanins and antioxidant capacity when compared to HACD at 90°C.
Multilingual information for foreign residents in Japan: a survey of government initiatives
Authors: Gottlieb Nanette
Published: April 2018

In Japan, translation of important information for foreign residents into community languages has occurred for many years mainly at the local government level rather than the national, largely because the national government has been slow to acknowledge Japan’s increasing diversity given the enduring national belief in ethnolinguistic homogeneity. In recent years, however, this has begun to change: although the bulk of the translation activity for foreign residents still occurs at grassroots level through the agency of local government and private organizations, the national government has begun to view such residents as seikatsusha ‘people making their lives in Japan’ rather than as visitors passing through. This article examines the provision of translated multilingual information to newcomer foreign residents in Japanese communities by both local and national government in order to examine this change.

Published: April 2018

Background

There is paucity of information on the adverse effects of alcohol – chloroquine interaction on hematological parameters. To investigate the effects of concurrent administration of chloroquine and ethanol on hematologic parameters of adult Wistar rats and the ameliorative role of vitamin B12 and folic acid supplementation on any adverse effects.

Methods

Some 30 adult Wistar rats weighing 120–200 g were assigned to six major groups of five rats each according to their weights. The control group A was fed with normal rat chow and water. The experimental groups B–F were administered with drugs for a period of 7 days as follows: B (chloroquine only); C (ethanol only); D (chloroquine+ethanol); E (chloroquine+ethanol+vitamin B12); and F (chloroquine+ethanol+vitamin B12+folic acid). Blood samples were collected from each animal by cardiac puncture to determine red blood cell (RBC) count, white blood cell (WBC) count, packed cell volume (PCV), hemoglobin (Hb), mean corpuscular hemoglobin concentration, mean cell volume (MCV), and mean cell hemoglobin (MCH). Liver enzymes, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were analyzed to test for liver function.

Results

Group D indicated lower PCV, Hb, MCV, MCH, and greater WBC compared with control. Group E indicated greater (p<0.05) PCV, Hb, and RBC compared with Group D. Greater (p<0.05) MCV and MCH, and lower WBC and RBC were observed in Group F compared with Group D. Furthermore, Group D rats indicated greater (p<0.05) mean AST and ALT compared with Groups A, E, and F.

Conclusions

Concurrent administration of chloroquine and alcohol indicated adverse effects on hematologic parameters of Wistar rats. The administration of vitamin B12 and folic acid appeared to ameliorate these adverse effects.

Published: April 2018

Background

The increasing prevalence of overweight and obesity is a critical public health problem for women. The negative effect of stress on memory and cognitive functions has been widely explored for decades in numerous research projects using a wide range of methodology. Deterioration of memory and other brain functions is a hallmark of Alzheimer’s disease. Estrogen fluctuations and withdrawal have myriad direct effects on the central nervous system that have the potential to influence cognitive functions. The present study aims to compare the effect of stress on the cognitive functions in overweight/obese women before and after menopause.

Methods

A total of 142 female subjects constituting women before menopause between the ages of 18 and 44 years and women after menopause between the ages of 45 and 60 years were included in the sample. Participants were categorized into overweight/obese groups based on the body mass index. The major tool perceived stress scale was used for measuring the perception of stress. On the basis of the stress scale measurement, each group was classified into with stress and without stress. Addenbrooke’s Cognitive Examination-III was used for measuring the cognitive functions.

Results

Premenopausal women with stress showed a significant (p<0.05) decrease in the cognitive parameters such as attention and orientation, fluency, language and visuospatial ability. Memory did not show any significant changes in this group. Whereas, in the postmenopausal stressed women, all the cognitive functions except fluency showed a significant (p<0.05) decrease.

Conclusions

Stress is a significant factor on the cognitive functions of obese and overweight women before and after menopause. Practice of yoga and encouragement in activities like gardening, embroidery, games and relaxation techniques should be recommended to prevent stress. Insights into the neurobiology before and after menopause can be gained from future studies examining the effect on the hypothalamic-pituitary-adrenal axis in relation to cognition and stress.
Neuroprotective effect of curcumin nanoparticles against rat model of status epilepticus induced by pilocarpine
Authors: Khadrawy Yasser A. , Sawie Hussein G. , Hosny Eman N.
Published: April 2018

Background

The present study aims to investigate the neuroprotective effect of curcumin nanoparticles (Cur-NP) on the rat model of status epilepticus (SE) induced by pilocarpine.

Methods

In the present study, animals were divided into three groups: control animals, rat model of SE induced by a single dose of pilocarpine (380 mg/kg) injected intraperitoneally, and rat model of SE that received a daily intraperitoneal injection of Cur-NP (50 mg/kg) for four consecutive days prior to pilocarpine administration.

Results

The present results revealed a state of oxidative stress in the cortex and hippocampus of rat model of SE as compared to control. This was evident from the significant increase in lipid peroxidation and the significant decrease in reduced glutathione and nitric oxide. In addition, a significant increase in the levels of tumor necrosis factor-alpha (TNF-α) and caspase-3 was detected in the two studied brain regions of rat model of SE. The activities of acetylcholinesterase (AchE) and Na+/K+-ATPase decreased significantly in the cortex and hippocampus of rat model of SE. Protection with Cur-NP prevented oxidative stress and improved the elevated level of caspase-3 in the hippocampus and cortex and the hippocampal TNF-α to nonsignificant changes. Although Cur-NP prevented the decrease in AchE activity in the two studied brain regions, it failed to return Na+/K+-ATPase activity to its normal value.

Conclusions

It is clear from the present findings that Cur-NP could prevent the oxidative stress and neuroinflammation and cell death that were induced during SE. This in turn may help in ameliorating the subsequent cascades of events that follow SE and its development into epileptogenesis.
Evaluating of β-carotene role in ameliorating of favism-induced disturbances in blood and testis
Authors: Koriem Khaled M. M. , Arbid Mahmoud S.
Published: April 2018

Background

Favism is an acute hemolytic anemia occurs in glucose 6-phosphate dehydrogenase (G6-PD) deficient individuals. β-Carotene occurs in vegetables such as carrots. This study aimed to establish the therapeutic effect of β-carotene to rebalance the testicular and blood proteins disturbances in favism.

Methods

Forty-eight male rats were divided into six equal groups; Groups 1, 2 and 3: normal rats were daily oral administrated with 1 ml saline, 1 ml corn oil and β-carotene (60 mg/kg dissolved in 1 ml corn oil), respectively, once a day over 15 days period. Group 4 (favism-induced group): normal rats injected intraperitoneal (ip) with diethyl maleate (5 μl/rat) and after 1 h injected ip with 1/3 LD50 of faba beans ethanolic extract for 15 day to induce favism. Groups 5 and 6: favism-induced rats were daily oral administered with 30 and 60 mg/kg β-carotene dissolved in 1 ml corn oil, respectively, once a day over 15 days.

Results

The results revealed that oral administration of corn oil or β-carotene into normal rats over 15 days period did not induce any change. In favism-induced groups, hematological parameters, liver function, serum glucose, G6-PD, luteinizing and follicle-stimulating hormones and sex-hormone binding globulin showed significant increase. Moreover, serum testosterone and dehydroepiandrosterone sulfate, testicular G6-PD, 3β-hydroxy steroid dehydrogenase, cholesterol and total protein were decreased. Treatment with both doses of β-carotene into favism groups restored all the abovementioned parameters to approach normal values. Favism inhibited blood proteins while β-carotene treatment into favism group stopped blood cells damage and blood proteins inhibition. These results were supported by histological studies.

Conclusions

In conclusion, taken β-carotene into favism group abolished testicular and blood proteins disturbances and this effect was dose dependent.

Published: April 2018

The use of programable logic controllers (PLC) technology in electrical networks 230 V causes electromagnetic radiation that interferes with other electrical equipment connected to the network [1–4]. Therefore, this article describes the issues of electromagnetic compatibility (EMC) of new PLC adapters used in IP broadband services in a multi-user environment. The measurements of disturbing electromagnetic field originated in PLC adapters were made in a certified laboratory EMC (laboratory of electromagnetic compatibility) in the Institute of Electrical Engineering at Faculty of Electrical Engineering and Information Technology of the Slovak University of Technology in Bratislava. The measured spectra of the radiated electromagnetic field will be compared with the results obtained when testing older PLC modems [5].

An adaptive multigrid conjugate gradient method for the inversion of a nonlinear convection-diffusion equation
Authors: Liu Tao
Published: April 2018

This paper considers the problem of estimating the permeability in a nonlinear convection-diffusion equation. To overcome the large calculation burden of conventional methods, we apply an adaptive multigrid conjugate gradient method to solve this inverse problem. This new method combines the multigrid multiscale idea with the conjugate gradient method, and adopts the necessary condition that the optimum solution should be the fixed point of the multigrid inversion method. Some numerical results verify that the proposed method both dramatically reduces the required computations and improves the inversion quality.

Published: April 2018

We consider the inverse scattering problem in a layer-homogeneous elastic structure filling a half-plane. Scattering data is the seismic wave field registered on the boundary with a surface point source. We prove that velocities of longitudinal and transverse waves, and a density of the medium are recovered by a unique way. The algorithm of the inverse problem solution is based on the τ-p Radon transform. Also, we present some results of numerical modeling for waves propagation and solving of the inverse problem.
Sentiment Polarity Detection in Bengali Tweets Using Deep Convolutional Neural Networks
Authors: Sarkar Kamal
Published: April 2018

Sentiment polarity detection is one of the most popular sentiment analysis tasks. Sentiment polarity detection in tweets is a more difficult task than sentiment polarity detection in review documents, because tweets are relatively short and they contain limited contextual information. Although the amount of blog posts, tweets and comments in Indian languages is rapidly increasing on the web, research on sentiment analysis in Indian languages is at the early stage. In this paper, we present an approach that classifies the sentiment polarity of Bengali tweets using deep neural networks which consist of one convolutional layer, one hidden layer and one output layer, which is a soft-max layer. Our proposed approach has been tested on the Bengali tweet dataset released for Sentiment Analysis in Indian Languages contest 2015. We have compared the performance of our proposed convolutional neural networks (CNN)-based model with a sentiment polarity detection model that uses deep belief networks (DBN). Our experiments reveal that the performance of our proposed CNN-based system is better than our implemented DBN-based system and some existing Bengali sentiment polarity detection systems.
Deep Learning-Based Language Identification in English-Hindi-Bengali Code-Mixed Social Media Corpora
Authors: Jamatia Anupam , Das Amitava , Gambäck Björn
Published: April 2018

This article addresses language identification at the word level in Indian social media corpora taken from Facebook, Twitter and WhatsApp posts that exhibit code-mixing between English-Hindi, English-Bengali, as well as a blend of both language pairs. Code-mixing is a fusion of multiple languages previously mainly associated with spoken language, but which social media users also deploy when communicating in ways that tend to be rather casual. The coarse nature of code-mixed social media text makes language identification challenging. Here, the performance of deep learning on this task is compared to feature-based learning, with two Recursive Neural Network techniques, Long Short Term Memory (LSTM) and bidirectional LSTM, being contrasted to a Conditional Random Fields (CRF) classifier. The results show the deep learners outscoring the CRF, with the bidirectional LSTM demonstrating the best language identification performance.

Authors: Srinivasa Rao T.C. , Tulasi Ram S.S. , Subrahmanyam J.B.V.
Published: April 2018

Nowadays, electrical power system is considered as one of the most complicated artificial systems all over the globe, as social and economic development depends on intact, consistent, stable and economic functions. Owing to diverse random causes, accidental failures occur in electrical power systems. Considering this issue, this article aimed to propose the use of deep belief network (DBN) in detecting and classifying fault signals such as transient, sag and swell in the transmission line. Here, wavelet-decomposed fault signals are extracted and the fault is diagnosed based on the decomposed signal by the DBN model. Further, this article provides the performance analysis by determining the types I and II measures and root-mean-square-error (RMSE) measure. In the performance analysis, it compares the performance of the DBN model to various conventional models like linear support vector machine (SVM), quadratic SVM, radial basis function SVM, polynomial SVM, multilayer perceptron SVM, Levenberg-Marquardt neural network and gradient descent neural network models. The simulation results validate that the proposed DBN model effectively detects and classifies the fault signal in power distribution system when compared to the traditional model.

Published: April 2018

In this article, first the model of 2×2 reversible logic gate is proposed after then the performance of the proposed designed is evaluated. With the increasing flow of information, data rate is increasing very rapidly. This has resulted in increased amount of heat dissipation from the processing nodes. Generally, electronic processors dissipate heat if the data rate is very high. Hence, this model will be very helpful for solving this problem. Evaluated performance of this model is based on the value of quality factor and extinction ratio. The quality factor and extinction ratio are evaluated under different conditions. The average extinction ratio of the design is 19.58 dB and the average quality factor is 53.03 dB. The optical cost of the proposed circuit is 1.
Review on Wavelength Division Multiplexing Free Space Optics
Authors: Magidi S. , Jabeena A.
Published: April 2018

Wavelength division multiplexing-based free space optics (WDM FSO) has emerged as a potential communication network candidate for last-mile access among other applications. FSO has received much attention in the last few years as a complement as well as an alternative to radio frequency-based communication due to spectrum crisis among other reasons. On the other hand, WDM has been considered as one of the next-generation optical access network candidates for bandwidth efficiency and increased data rates. A hybrid network of these two technologies thus has emerged as another research direction. In this article, we present the background, progress and the current state of WDM FSO.
Utility of serum resistin in the diagnosis of neonatal sepsis and prediction of disease severity in term and late preterm infants
Authors: Khattab Ahmed Anwar , El-Mekkawy Muhammad Said , Helwa Mohamed Ahmed , Omar Ehab Seif
Published: April 2018

Introduction

Resistin is a proinflammatory hormone recently proposed as a sepsis biomarker. Our aim was to evaluate the diagnostic and prognostic values of this marker in neonatal sepsis.

Methods

This is a prospective observational study that includes 60 term and late preterm neonates with proven and possible sepsis besides 30 healthy controls. Resistin and other biomarkers, like C-reactive protein (CRP), were measured within 2 h of neonatal intensive care unit (NICU) admission. Infants were monitored and the primary outcome was 30-day mortality.

Results

Resistin was higher among septic neonates compared with controls (P<0.001). Resistin had an area under the receiver operating characteristic (ROC) curve of 0.994 for differentiating septic infants from controls. The area under the curve (AUC) for differentiating infants with culture-proven sepsis from controls was 0.999 compared with an AUC of 1 for CRP. The other markers, like platelet count, were inferior to resistin and CRP. Resistin was positively correlated with CRP [Spearman’s correlation coefficient (rs)=0.55, P<0.001]. No significant differences in resistin levels were noted between survivors and non-survivors but resistin was higher among infants with severe sepsis (P=0.015) and among those who needed mechanical ventilation (P<0.001).

Conclusion

Resistin is useful for the diagnosis of neonatal sepsis. Resistin failed to predict mortality but was associated with indicators of disease severity.
Natural Beauty, Fine Art and the Relation between Them
Authors: Reiter Aviv , Geiger Ido
Published: April 2018

We defend three principal claims concerning natural beauty, artistic beauty and the relation between them. 1) Aesthetic pleasure in nature is typically and paradigmatically occasioned by the spatial form of natural kinds. 2) Breaking with a long-standing tradition, Kant claims that the presentation of such beautiful natural forms is not the end of the representational visual arts. Most art presents aesthetically the idea of humanity in our person. This is Kant’s Copernican revolution in the philosophy of fine art. 3) Although the representation of nature is not a sufficient condition of beauty in the representational visual arts, it is nonetheless a necessary condition of it.
Gottlob Ernst Schulzes skeptizistische Kant-Kritik in ihrer Relevanz für Arthur Schopenhauers Systemkonstitution
Authors: Elon Daniel
Published: April 2018

In 1792, Gottlob E. Schulze published one of the most important treatises in the era of the early critical reception of Kant’s transcendental philosophy: the skeptical treatise Aenesidemus. One of Schulze’s later students was the young Arthur Schopenhauer, whose examination of Kant’s philosophy was significantly influenced by Schulze. In this paper, it shall be established that this influence isn’t limited solely to the details of Schopenhauer’s critique of Kantian thinking, but rather extends to the systematic unfolding of Schopenhauer’s philosophy as a whole. In this respect, Schopenhauer’s The World as Will and Representation can be understood as a direct, positive answer to the questions left open by Schulze’s debate on the internal problems of Kant’s Critique of Pure Reason.
Arabic Localization of Video Games “Tomb Raider™ (2013)”: A Start or A Failure

Published: April 2018

Video games have been a new and attractive type of entertainment in the Arab world ever since the emergence of computers, and they are still of interest to young Arabs today. Video game localization movements have set out to translate, and sometimes adopt, video games into several languages and settings. Nevertheless, localization into Arabic is still very recent. In this paper, an analysis of translation activities of video game Tomb Raider™ (2013) is made in order to investigate the extent to which the translation of some selected linguistic assets in the aforementioned video game can be considered to incorporate what the notion of localization truly suggests. Moreover, this study attempts to define and evaluate the use of some deferent-perspective translation strategies as tools for assessing the scope of the translation and its target.
Information Behavior of Electrical Engineering and Computing Doctoral Students and Their Perception of the Academic Library’s Role: A Case Study in Croatia
Authors: Petr Balog Kornelija , Badurina Boris , Lisek Jadranka
Published: April 2018

Th aim of the paper is to present findings of a study on information sources and information behavior of doctoral students at the Faculty of Electrical Engineering and Computing at the University of Zagreb, Croatia. The study also looked into student perceptions of the role of the academic library and their attitudes toward it as a legitimate partner in the research process, as doctoral students are required to publish the results of their doctoral research in high-ranking peer-reviewed journals during their course of study. However, they rarely use the library and its services; the study was undertaken with the intent to obtain insight into the students’ information behavior as well as needs and reasons for overlooking the library as a relevant partner in their research process. The online survey was conducted on a sample of 138 postgraduate students, with semi-structured interviews with five postgraduate students also conducted. The findings show a dominant student orientation towards online sources such as online databases and Google Scholar. Students tend to overlook the library as a relevant information source but have positive attitudes toward librarians (their knowledge, skills and courtesy). The library needs to become more active in promoting its services and, especially in the domain of postgraduate education, needs to be regarded as a necessary location for any serious research work, where librarians are regarded as cooperating partners in the research process. There were a few limitations of the study: respondents were unwilling to dedicate their time to this research and therefore the interviews were too short to examine the topics discussed in-depth, while the sample was extremely homogeneous, making the results only in part transferable to other contexts.
Document Exchange Balance in LIS Professional Virtual Communities: A Study of Two Iranian Email Groups
Authors: Asadi Saeid , Atash Deligani Fatemeh
Published: April 2018

The purpose of this paper is to show the features of document sharing in library and information professionals’ virtual communities. A novel method is offered to investigate document request and provision through group emails and compare personal and professional contacts. Using different search operators on two major Iranian email groups, IranKIS and LIS, 173 message pairs were identified as document request/ provision transactions during 2015–2016. Directed graphs were built for completed interlibrary document exchange transactions with results showing that 23 % of requests had LIS topics while three universities were distinguished as the hub organizations for document providing. Iranian librarians use email-based communities as a quick and reliable tool to provide documents for library users and themselves. The mixed combination of email exploration and social network analysis offered in this work can be used to visualize document exchange transactions among organizations and cities in virtual communities.
Robust Harms
Authors: Taylor Isaac
Published: April 2018

Philip Pettit has argued that more robust harms are worse than less robust ones, other things equal, and thinks that appealing to this presumption can help us rationalise the appeal of a number of widely-held moral principles. In this paper, I challenge this view. I argue against the presumption and suggest that, even if it were correct, it could not give much support to the moral principles that Pettit discusses. I also claim, however, that Pettit has the resources at his disposal to explain the attraction of the principles in another way, and lay out how such an explanation would proceed. As moral heuristics, at least, these principles can be grounded on the need to maintain social norms necessary to guarantee individuals’ security.
Pettit on Love and Its Value: A Critical Assessment
Authors: Nyholm Sven
Published: April 2018

Philip Pettit has identified some interesting apparent commonalities among core human values like love, friendship, virtue, and respect. These are all, Pettit argues, ‘robustly demanding’: they require us to provide certain benefits across ranges of alternative scenarios. Pettit also suggests a general ‘rationale’ for valuing such goods, which draws on his work on freedom. In this paper, I zoom in on love in particular. I critically assess whether Pettit’s schematic account of love’s value adequately captures what we typically value in valuing love. And I scrutinize the analogy Pettit suggests between the rationale for valuing freedom and his rationale for valuing love. My conclusion is that whereas Pettit’s account of love and its value does not strictly speaking contain false propositions, it ends up being a somewhat skewed account of love’s value. Finally, I bring up some widely discussed aspects of love’s value not captured by Pettit’s account.

I-cored Coil Probe Located Above a Conductive Plate with a Surface Hole
Authors: Tytko Grzegorz , Dziczkowski Leszek
Published: April 2018

This work presents an axially symmetric mathematical model of an I-cored coil placed over a two-layered conductive material with a cylindrical surface hole. The problem was divided into regions for which the magnetic vector potential of a filamentary coil was established applying the truncated region eigenfunction expansion method. Then the final formula was developed to calculate impedance changes for a cylindrical coil with reference to both the air and to a material with no hole. The influence of a surface flaw in the conductive material on the components of coil impedance was examined. Calculations were made in Matlab for a hole with various radii and the results thereof were verified with the finite element method in COMSOL Multiphysics package. Very good consistency was achieved in all cases.
Measurement System Analyses – Gauge Repeatability and Reproducibility Methods
Authors: Cepova Lenka , Kovacikova Andrea , Cep Robert , Klaput Pavel , Mizera Ondrej
Published: April 2018

The submitted article focuses on a detailed explanation of the average and range method (Automotive Industry Action Group, Measurement System Analysis approach) and of the honest Gauge Repeatability and Reproducibility method (Evaluating the Measurement Process approach). The measured data (thickness of plastic parts) were evaluated by both methods and their results were compared on the basis of numerical evaluation. Both methods were additionally compared and their advantages and disadvantages were discussed. One difference between both methods is the calculation of variation components. The AIAG method calculates the variation components based on standard deviation (then a sum of variation components does not give 100 %) and the honest GRR study calculates the variation components based on variance, where the sum of all variation components (part to part variation, EV & AV) gives the total variation of 100 %. Acceptance of both methods among the professional society, future use, and acceptance by manufacturing industry were also discussed. Nowadays, the AIAG is the leading method in the industry.
Testing an Impedance Non-destructive Method to Evaluate Steel-Fiber Concrete Samples
Authors: Komarkova Tereza , Fiala Pavel , Steinbauer Miloslav , Roubal Zdenek
Published: April 2018

Steel-fiber reinforced concrete is a composite material characterized by outstanding tensile properties and resistance to the development of cracks. The concrete, however, exhibits such characteristics only on the condition that the steel fibers in the final, hardened composite have been distributed evenly. The current methods to evaluate the distribution and concentration of a fiber composite are either destructive or exhibit a limited capability of evaluating the concentration and orientation of the fibers. In this context, the paper discusses tests related to the evaluation of the density and orientation of fibers in a composite material. Compared to the approaches used to date, the proposed technique is based on the evaluation of the electrical impedance Z in the band close to the resonance of the sensor–sample configuration. Using analytically expressed equations, we can evaluate the monitored part of the composite and its density at various depths of the tested sample. The method employs test blocks of composites, utilizing the resonance of the measuring device and the measured sample set; the desired state occurs within the interval of between f=3 kHz and 400 kHz.
