Extreme territorial aggression by urban Peregrine Falcons toward Common Buzzards in South-West England
Authors: Dixon Nick , Gibbs Andrew
Published: February 2019

Peregrine Falcons (Falco peregrinus) breeding on a city centre church in Exeter, in the south-west of England, have been studied in detail since first occupation in 1997. During this period, changes in both male and female falcons have been recorded. Following the arrival of a new female Peregrine in 2009, a dramatic change in behaviour towards Common Buzzards (Buteo buteo) on passage over the city was noted. Buzzards flying over Exeter are attacked by the falcons, especially so when in proximity to the church. We have attempted to document these attacks through our own observations, with additional information from local residents and wildlife organisations. Further records have come from veterinary surgeries and wildlife rehabilitators regarding injured buzzards found in the city. This paper documents the extreme levels of territorial aggression as demonstrated by the pair of Peregrines during cooperative attacks on Buzzards. We reveal this unique interspecific behaviour by summarising the number, frequency, timing and outcome of attacks undertaken over an eight-year period. We describe and illustrate the strategy employed by the Peregrines during a typical attack, plus consider implications on breeding productivity and the future scenarios should one of the current pair be replaced.
Enhanced Thermal and Mechanical Properties of Polymer Reinforced with Slightly Functionalized Graphene Nanoplatelets

Published: February 2019

Slightly oxidized graphene nanoplatelets (GNPs) were functionalized using 3-hydroxytyramine hydrobromide. The functionalized GNPs, denoted as fGNPs, were examined using Fourier transform infrared and a Raman spectrometer, which revealed a slight reduction in the sp2 network domain compared with unmodified GNPs. Compared with previous reports on functionalized highly oxidized graphene, the degree of the sp2 structural destruction was less, as revealed by Raman analysis. The aim was to address the challenges of high agglomeration of graphene in polymer matrix and high destruction of graphene’s conjugal structure during functionalization, which deteriorates graphene’s excellent properties and makes it less effective in improving the polymer’s properties. This was achieved by slight functionalization of GNPs because they contained little oxygen functional groups. In this study, a thermal conductivity increase of about 295 % was recorded when 6.67 wt. % fGNPs were incorporated into the poly(vinylidene fluoride) (PVDF) matrix. Also, with 3.34 wt. % of the GNPs composite, the tensile strength and Young’s modulus were measured with an increase of about 64 % and 100 %, respectively. The enhanced properties of the polymer nanocomposites were due to better dispersion of fGNPs and interaction with the polymer matrix compared to unfunctionalized GNPs composites as was indicated by a scanning electron microscope. The composites were prepared by solution blending and melt compounding process. Such composites can find application in automobile and aerospace industries in which good mechanical and thermal properties are required.

Published: February 2019

Garlic (Allium sativum L.) is the most important species of the Allium genus and an important vegetable crop throughout the world. Garlic is widely used as an obligatory part in many cooked dishes. It is one of the ancient plants playing one of the most important dietary and medicinal roles in human beings for centuries. Garlic possess many therapeutic properties including antimicrobial, antiviral, antifungal, cardioprotective, neuroprotective, anticarcinogenic, antimutagenic, anti-hypertensive, anti-diabetic and antioxidant. This study has focused on the comparison of the total polyphenols content, the total sulphur content and antioxidant activity of the studied varieties of garlic in the area of Nitra, Slovak Republic. The analyzed samples of garlic were collected at the stage of full maturity. TPC was measured using the spectrophotometric method of Folin-Ciocalteu agents. TPC in studied varieties of garlic were determined in the range 742 mg.kg-1 (Mojmír) to 635 mg.kg-1 (Makoi). The determination of the total sulfur content was based on dry combustion in the presence of oxygen and allows for the quantitative conversion of sulfur to SO2. Statistically significant highest level of TSC recorded in 0.751% (Mojmír) and the lowest level was in 0.523% (Makoi). Antioxidant activity was determined by the spectrophotometric method using a compound DPPH˙ (2.2-diphenyl-1-picryhydrazyl). The highest value of AA was measured in Mojmír (17.7%). The lowest level was observed in Makoi (12.4%). In all studied samples of garlic was confirmed by the strong dependence of the total polyphenols content, total sulfur content and antioxidant activity.

Published: February 2019

Pleurotus spp. is in the top three of the most widely grown mushroom in the world's production. In connection with its intensive production in a conventional way, the risk of contamination with the most pathogens is avoided. The work deals with identification of the pathogen on the production crop of oyster mushroom, and with determining the optimal dilution of the commercially available disinfectant with 47 g/kg (4.7%) sodium hypochlorite to eliminate it. We found that the lethal dose of sodium hypochlorite for pathogen Pseudomonas tolaasii and for Pleurotus ostreatus is different, so we recommend using the disinfectant in specified dilutions even during the cultivation of oyster mushroom.

Authors: Tkáčová Jana , Pavelková Adriana , Sajdová Alena , Angelovičová MÃ¡ria
Published: February 2019

The aim of this work was to compare the quality of selected fish product samples (cod in mayonnaise) of Slovak and Czech producers at the beginning and end of durability by sensory analysis. The products were approximately the same expiration date and were stored in a refrigerator. The samples were evaluated by a 5 point evaluation system with trained evaluators. The following descriptors have been assessed: general appearance, color, smell, harmonicity taste, palatability of the product, balance of fish-mayonnaise taste, salted, acidity, bitterness and possible foreign flavor. The results of evaluation were that product exhibits characteristic sensory properties during its use. The approaching ending of the durability date is the gradual overlapping of fish taste, such as an acetic taste, as reflected assessors' evaluation. Assessors put emphasis on balance of taste.
Protestantismo, história e cultura escrita: um balanço da produção discente na Pós-Graduação brasileira
Authors: Sepulcro Júnior Jaime Magalhães , Galvão Ana Maria De Oliveira
Published: February 2019

O artigo objetiva mapear e analisar a produção discente realizada na pós-graduação brasileira que se debruça sobre a interface entre Protestantismo e Cultura Escrita no Brasil, a partir de uma abordagem histórica. Baseia-se teoricamente nos estudos realizados no âmbito da História Cultural. Analisamos inicialmente 66 trabalhos, entre teses e dissertações, produzidos no período de 2004 a 2016. Em um segundo momento, realizamos a análise, de modo mais aprofundado, de sete estudos que tiveram como objeto, especificamente, a relação entre protestantismo, leitura e escrita. A pesquisa nos permitiu verificar que essa relação aparece principalmente nas referências que os autores fazem: à atividade educativa dos protestantes no Brasil; aos impressos protestantes; à atividade editorial protestante; e às atividades dos vendedores/distribuidores de bíblias e de outros impressos. A relação com a cultura escrita é vista na maior parte dos trabalhos como algo “já dado”, não se constituindo propriamente como problematização do objeto de pesquisa. A maioria deles aponta para uma relação prévia entre protestantismo e cultura escrita - antes de sua chegada no Brasil - na medida em que as diferentes denominações protestantes atuaram, significativamente, em outros contextos históricos e geográficos, na circulação social do escrito e na aproximação de indivíduos com a leitura e a escrita.
Interações de alunos com Transtorno do Espectro Autista na escola
Authors: Formagio Martins Alessandra Dilair , Bacelar Monteiro Maria Inês
Published: February 2019

O O artigo tem por objetivo analisar as interações sociais entre uma criança com Transtorno do Espectro Autista (TEA) e seus pares, professor, monitor e pesquisador, ocorridas numa sala de aula do Ensino Fundamental de uma escola especial frequentada por 4 crianças de 6 a 10 anos, todas com TEA, enfatizando os processos de significação que surgem nesse contexto. Olhar para a educação de pessoas identificadas como TEA, com fundamentos na perspectiva histórico-cultural do desenvolvimento humano, implica caminhar no sentido oposto à maioria das produções sobre essa temática, que considera que uma das principais características das pessoas com TEA é a dificuldade de interação social e essa característica é tomada como “um fato dado” a partir do qual se parte para refletir sobre o desenvolvimento, sem problematiza-lo. As situações foram registradas em diário de campo e em filmagens, o que permitiu uma análise minuciosa das interações estabelecidas, bem como a identificação de indícios dos processos de significação e subjetivação construídos a partir dessas relações. Os achados apontam para possibilidades de uma atuação educacional centrada nas relações, que privilegie a elaboraçãocompartilhada de sentido na comunicação e aprendizado entre o aluno com transtorno do espectro autista e os outros.

Critique phénoménologique d’une approche neuronale de la conscience
Authors: Petit Jean-Luc
Published: February 2019

Résumé: La conscience est toujours conscience de quelque chose, généralement une chose autre qu’elle-même - mais quelle sorte de chose est donc la conscience, considérée en et pour elle-même? Naguère redoutable paradoxe qu’une science sérieuse abandonnait volontiers aux philosophes, la conscience a-t-elle été ramenée finalement à la condition d’un objet de science parmi les autres? Le développement d’une nouvelle «neuroscience de la conscience» depuis une vingtaine d’années est souvent présenté comme une avancée naturelle pour une science forte de son succès dans l’explication des fonctions cognitives sur la base des mécanismes neuronaux du cerveau humain. Conçue, elle aussi, originairement, comme «science de la conscience», mais sur la base de l’immanence du sujet conscient à sa propre expérience vécue, la phénoménologie doit-elle réfréner son sens du paradoxe devant le projet de cette neuroscience de la conscience, pour ne pas être accusée d’irrationalisme? Faisant retour sur le dialogue Changeux-Ricœur, je relève les objections du phénoménologue à l’objectivation de notre expérience de la conscience sur la base de mécanismes corrélatifs dans le cerveau et j’examine sur l’exemple représentatif de la théorie neuronale de Changeux, Dehaene et al. dans quelle mesure cette critique phénoménologique garde une pertinence.
A constituição do Eu em Merleau-Ponty e o estatuto da projeção na psicanálise freudiana
Authors: Santos Renato dos
Published: February 2019

Resumo: As reflexões desenvolvidas ao longo do presente artigo se apresentam como desdobramento do texto3 de Alfredo Pereira Jr., mais especificamente sobre a noção de Eu sentiente e do conceito de “projeção”, desde a psicanálise freudiana. Num primeiro momento, analisa-se de que forma Merleau-Ponty, em contraste com as filosofias empirista e racionalista, reformula a noção da subjetividade, num plano fenomenológico e ontológico. O Eu se define não mais por uma sorte de pensamento, ou por uma causalidade de leis físicas e químicas, mas pelo entrelaçamento na carnalidade do mundo. Em seguida, investiga-se a noção de projeção em Freud, a fim de evidenciar como tal conceito ocupa a função de “proteção” para o Eu. A projeção (de)limita o “lugar” necessário para que o Eu possa se desenvolver, conforme mecanismo de defesa. Por fim, sustenta-se que a noção de Eu merleau-pontyano e a projeção freudiana convergem, na medida em que ambas só podem ser pensadas como experiências dentro de um mundo de relações que ocorrem por uma dimensão inconsciente, aproximando-se, assim, com a proposta de Pereira Jr..

Rapid surface roughness testing method and instrument
Authors: Li Xiaojie , Zhao Kai
Published: February 2019

Surface roughness presents microsurface topographic variances and irregularities; it is an important characteristic in many experiments and model construction. A quick testing method and an instrument for surface roughness measurement were developed in this study. A laser was emitted onto the test subject, the reflected light was directed to the camera and the images were then captured through a linear scanning process. The three-dimensional (3D) coordinates of the measurement area were then obtained after image processing and coordinate transformation, and multiple surface roughness levels were calculated by employing the 3D coordinates. The precision experiment and field experiment showed that the instrument has a maximum average comparative error of 2·93%, and the instrument was able to replicate the 3D structure of the test subjects precisely. A series of surface roughness parameters was calculated as the final measurements. The instrument and the controlling/postprocessing software are available by contacting the authors.
Technical aspects of mercury intrusion porosimetry for clays
Authors: Yuan Shengyang , Liu Xianfeng , Buzzi Olivier
Published: February 2019

This paper presents a comprehensive and consistent investigation on three technical aspects associated with mercury intrusion porosimetry (MIP) applied to clayey soils: the effect of intrusion rate, the effect of the freeze-drying method and the influence of sample size. Although a limited number of publications provide recommendations about the MIP technique, the aforementioned effects were largely left unaddressed. This study was performed on four different soils, having different microstructures. In order to obtain a quasi-static condition at the applied pressure, the smallest intrusion rate was suggested to be used in the MIP tests. It was found that the freezing technique does modify the pore size distribution, due to expansion of water on freezing. The more water in the soil specimen, the more pronounced the effect. The specimen size also matters for similar reasons. The outcome of this study provides a technical basis for MIP on clayey soils.

Media Resource Center Management in Higher Education
Authors: Lawrason Robin E. , Parkhurst Bruce
Published: February 2019

Changes in the organization of learning resources including language/learninglabs have occurred over the years. Surveys within higher education over the last tenyears indicate less local autonomy and more centralized control, either withinindividual colleges or within central media or library facilities. It is not clear whetherlibrary involvement is advantageous in all institutions. Factors affecting successfulintegration include the age, size, and traditions of the university, training and skills ofstaff and director, support of the central administration, and a clear mission for theuse of learning resources.An earlier version of this paper was presented for IALL at the Annual Conventionof the Association for Educational Communications and Technology in 1984 in Dallas,Texas.
Using Technology in Language Teaching and Listening Comprehension

Published: February 2019

Previous arguments concerning the influence of technology onlearning have proposed that it is either the medium that influenceslearning or it is the instructional design applied to a particularmedium that enhances knowledge acquisition (Oark 1983; Kozma1991). Absent from both perspectives is the role of the teacher andhowheorshemustunderstandandmanagenotonlythetechnologyand the instructional materials used, but must also be cognizant ofother instructional components necessary for the effective use oftechnology. This paperreemphasizes the status of the teacher as thecentral decision-maker of technology use in language teaching, orin this instance, media-basedlisteningcomprehension. Previousresearch and recent results of a qualitative study on the" mismanagement"of listening comprehension technology support andreflect how a teacher's combined knowledge of students' preferencesand needs, sound pedagogical and theoretical strategies, andthe media and materials used can influence language learningthrough media-based activities.
Applying Tools and Techniques of Natural Language Processing to the Creation of Resources for Less Commonly Taught Languages
Authors: McShane Marjorie
Published: February 2019

This paper proposes that research results from the area of naturallanguage processing could effectively be applied to creating softwareto facilitate the development oflanguage learning materials foranynaturallanguage. We will suggest that a knowledge-elicitationsystem called Boas, which was originally created to support amachine-translation application, could be modified to supportlanguage-learning ends. Boas leads a speaker of any natural Ianguage,who is not necessarily trained in linguistics, through a seriesof pedagogically-supported questionnaires, the responses to whichconstitute a" profile" of the language. This profile includes morphological,lexical and syntactic information. Once this structuredprofile is created, it can feed into virtually any type of system,including one to support language learning. Creating languagelearningsoftware using a system like this would be efficient in twoways: first, it would exploit extant cutting-edge research and technologiesin naturallanguage processin~ and second, it would permita single tool to be used for all languages, including less commonlytaught ones, for which limited funding for resource development isa bottleneck.

Bridging the Gap
Authors: Thompson Amy S. , Schneider Sandra L.
Published: February 2019

As language requirements burgeon at the post-secondary level inattempts to create global citizens out of college graduates,universities nationwide have seen a sharp increase in languagecourse enrollments, especially in the Less Commonly TaughtLanguage (LCTL) courses (Furman, Goldberg, & Lusin, 2007).While this is a positive trend from an intellectual and culturalpoint-of-view, the sudden growth presents a unique set of problemsfor course implementation. There has been a current trend ofoffering language courses online to meet increasing demands forcommonly taught languages (CTLs) (e.g., Chenoweth, Ushida, &Murday, 2006; Sanders, 2005), but little has been written aboutonline offerings for LCTLs (c.f., Winke, Goertler, & Amuzie, 2010).To respond to the need for high-quality pedagogical materials forLCTLs and to compensate for the lack of face-to-face classroomsettings, the Center for the Study of International Languages andCultures (CSILC) at the University of South Florida (USF) hascreated lessons in Dari, Pashto, and Urdu for the Global LanguageOnline Support System website (GLOSS; gloss.dliflc.gov)supported by the Defense Language Institute Foreign LanguageCenter. This paper is an analysis of considerations that informedthe process and products of these modules. A discussion ofimplications and directions for further study concludes the paper.
Collaboration through Wiki and Paper Compositions in Foreign Language Classes
Authors: Martinsen Rob A. , Miller Andrew
Published: February 2019

This study investigates the nature of collaboration on wikis as opposed tothe nature of collaboration resulting in a paper composition. In order tounderstand this phenomenon students were placed in groups of four andasked to write two essays during the semester. On one essay students wereasked to produce a composition in the target language on a wiki. Onanother they were asked to produce a composition that would be given tothe teacher in hard copy. Specific research questions includeddetermining to what extent students prefer collaborating to produce a wikior paper composition. Additionally, we attempted to determine, accordingto students, what the advantages and disadvantages of collaborating on awiki composition versus a paper composition are and what effect theseadvantages and disadvantages might have on collaboration. Data wascollected from over one hundred university students through likert-scaletype questions, open-ended written questions as well as face to faceinterviews. Findings indicate that the collaborative process on the wikireflected true collaboration where students had a hand in each part of thecomposition. On the other hand, while completing the paper composition,students generally handed their assigned portion to a single student in thegroup who was designated the compiler and would rarely see or commenton the other group members’ work. The authors also provide a discussionof specific advantages and disadvantages of wiki and paper-basedcompositions and important implications for practitioners.
The Electronic Portfolio as Assessment Tool and More
Authors: Cadd Marc
Published: February 2019

The utilization of portfolios has become more common in academia in thelast two decades. However, their usage in the language classroom is stillrelatively rare. Electronic portfolios (ePortfolios) offer students andinstructors numerous advantages over traditional means of assessment,including a means by which progress can be tracked longitudinally. Thesecollections of artifacts can be used to demonstrate proficiency toprospective employers and graduate schools. The author provides onemodel that incorporates and utilizes current technologies as a basis forstudent-compiled electronic portfolios. In this model, students provideevidence of having met the linguistic and cultural objectives for eachlanguage course they take. Much of this evidence comes from in-depth,self-reflective writing, in addition to a number of artifacts selected by thestudents with direction from instructors. Detailed assessment rubrics areprovided for evaluating both the electronic portfolio and the assignmentsthat usually serve as the bases for the ePortfolio’s artifacts. Thiscomprehensive model represents one alternative to assessment through“seat-time” or number of credit hours earned in a given language.

Cultures and Communities in the Virtual World
Authors: White Kelsey D.
Published: February 2019

Most of today's college students grew up as part of the Net Generation(Cooke-Plagwitz, 2009), and pedagogues may assume that motivatedstudents use technologies outside of class to improve their target languageskills. However, little research has been conducted to see how studentsactually use technology to engage with foreign cultures and communitiesbeyond the classroom setting. This exploratory study draws from bothquantitative and qualitative data sets to reveal the ways first-semesterstudents use technology to learn about German-speaking cultures andcommunities, and using Dörnyei's L2 Motivational Self System (2005 &2009), also shows how students' out-of-class learning via technologyrelates to their diverse motivations as language learners. Discussionincludes suggestions for exploring cultures and communities throughdigital tools both within and beyond the classroom setting.
Awareness and Corrective Feedback in Social CALL, Tandems, and E-Tandems
Authors: Guillén Gabriel
Published: February 2019

Previous studies have identified advantages for second languagelearning in computer mediated settings (Kern, 1995, Warschauer,1997, Blake, 2008), particularly through online interculturalcollaboration (Furstenberg et al, 2001, Vinagre, 2005, O’Dowd, 2007,Bower & Kawaguchi, 2011). However, face-to-face (tandems) andonline (e-tandems) language exchanges remain peripheral to foreignlanguage education (O’Dowd, 2010, 2013) and rely heavily oninstructor guidance (Beltz, 2003, Bower & Kawaguchi, 2011), in spiteof the proliferation of Language Learning Social Networking Sites(LLSNs) such as Livemocha, Busuu, Shared Talk, and The Mixxer(Dickinson College). In response, this paper analyzes tandem andsocial Computer Assisted Language Learning (sCALL) awareness andexperiences among students and instructors of Spanish at the collegelevel by means of a survey and two pilot studies on tandem learning.The results of this research should encourage administrators andinstructors to support tandem learning and implement tandem andsCALL activities as co-curricular, semi-guided projects. The need ofpreparation for the tandem experience is also emphasized, particularlyin regards to corrective feedback.
The first five days
Authors: Romjue Amanda
Published: February 2019

Facilitating lifelong language learning amongst students is a frequently mentioned goal of many language teachers. Teachers want their students to fall in love with the cultures and languages they have dedicated their lives to studying. However, igniting the spark for learning beyond the classroom can be a real challenge. In the current educational culture where motivation for learning is too often focused on extrinsic motivations like passing tests and making good grades, how do teachers redirect students toward intrinsic motivations like a love for learning? Research into various fields of study have provided evidence that it typically takes at least ten years of concerted effort to master most skills. From this premise it stands to reason that in order for language learners to reach higher levels of language proficiency, there is a need to promote learner autonomy that extends learning beyond the language classes students take in schools. Facilitating learner autonomy requires a reconceptualization of the way language classes are structured. Building upon goal theories, task-based language learning, and deep reflection within a transparent learning framework can help to provide students with the skills to continue learning beyond the classroom. This framework can set students on a more self-directed path toward language learning that is both intrinsically motivating and engaging. Throughout my own research and practice I have begun to develop a process to facilitate this type of learning environment for my students. In this paper, I share my own successes and challenges as I spent the first five days of a semester establishing expectations for facilitating learner autonomy.
Notes on the taxonomical, morphological and mucilage features of Capsella bursa-pastoris Medik. and Capsella rubella Reuter taxa (Brassicaceae)
Authors: KARAİSMAİLOĞLU Cengiz
Published: February 2019

In
this study, examinations on the taxonomical, morphological and mucilage
characters of the Capsella bursa-pastoris and Capsella rubella taxa growing in Turkey were performed. The
properties were acquired at the flowering and fruiting periods of inhabitants.
The samplings were made of 13 locations. In morphological revisions,
descriptions reported in Flora of Turkey of the studied taxa were reviewed in
view of the comprehensive assessments over 200 samples. In addition, surfaces
of the seeds were studied micromorphologically with scanning electron
microscope. Also, seed mucilage structures were examined in detail. The
mucilage in the studied taxa was in the pectin or cellulose structure. The
columellae figures were prominent or flattened. Furthermore, soil adhesion
capacities of the examined taxa varied between 248 mg and 344 mg. The
occurrence of the mucilage in seeds may provide an important adaptive feature
in dispersal and colonization of Capsella
taxa.
From Velázquez to Picasso: Proposal of Artistic Mediation Activities for People with Dementia
Authors: Hernández Belver Manuel , Hernández Clara
Published: February 2019

This paper describes the design of a program of activities of arts education for people with dementia based on visits to the Prado Museum and the Reina Sofia National Art Center Museum (Spanish anagram, MNCARS) of Madrid, and carried out by a team of researchers and artist-teachers. The program, called “Tenemos cita con el arte” (We have a date with art), in addition to the visits, included workshops of artistic activities. The basic aspects taken into account by the team of artist-teachers for the design of the itineraries in the two above-mentioned museums and the design of the artistic activities are specified. The museum itineraries, which included works of Velázquez and Goya (Prado Museum), and of Dalí, Juan Gris, Miró, Lipchitz, and Picasso (MNCARS) are described, as well as the artistic activities carried out by the participants, based on these itineraries. The considerations set out in this work can be extended to other are centers, so that they can be used as contexts for the promotion of the well-being and social inclusion of people with dementia by artist-teachers working in multidisciplinary teams.

A cobertura do solo e sua temperatura superficial estão associadas; portanto, alterações provocam mudança microclimática devido emissão de radiação eletromagnética na faixa termal. Neste estudo objetivou-se analisar a relação da cobertura do solo com a Temperatura Superficial Aparente (TSA) em área periurbana do cerrado através de imagens de satélite. Por meio de procedimentos de Processamento Digital de Imagens como a classificação supervisionada que determinou as tipologias de cobertura do solo, bem como operações aritméticas que produziram imagens de temperatura da superfície em graus Celsius, avaliou-se sua relação em duas épocas distintas: 1985 e 2011. Os resultados demonstram que para o ano de 1985, dos cinco grupos de amostras de cobertura do solo, Pastagem apresentou-se de forma expressiva em 50% da área. De 1985 para 2011 verificou-se aumento de área para as classes de Pastagem, Vegetação Nativa e Área Urbana; e, de redução de área para as classes Solo Exposto e Cultura Agrícola. Em relação à TSA, as médias de temperatura das classes sofreram aumentos significativos. As diferenças das médias para cada classe, foram: Pastagem (+4,65 °C), Vegetação Nativa (+4,25 °C), Área Urbana (+4,87 °C), Solo Exposto (+5,33 °C) e Cultura Agrícola (+1,48 °C). As maiores TSA destacam-se nas classes Solo Exposto e Área Urbana, enquanto as menores nas classes com cobertura vegetal, como cultura agrícola e vegetação nativa.

An Empirical Study of Customers’ Awareness towards Value Added Services at Banks
Authors: Kumar Vishal
Published: February 2019

The growth of value-added services in the economy cannot undermine the relevance of information and communication technology at any point in time, because it plays a critical role in satisfying the needs of customers. Nevertheless, the question arises whether the customers are aware of the use of IT-enabled services. The current study focuses its attention on the Value-added Services i.e., the services that deliver value to the customers and its impact on customers’ satisfaction by taking into consideration their awareness level. For the purpose of a study, two public sector banks and two private sector banks have been selected from Chandigarh Tricity, India i.e., (Chandigarh, Panchkula, and Mohali) and customers are approached to study the impact of their awareness level on the value-added services of these banks. A sample of 400 customers of different age, qualification, occupation, annual income and locality was included in Data Analysis. Descriptive analysis was made with the help of SPSS. It is quite interesting to note that both public and private sector banks are focusing on the need of value-added services for customers so that they can easily meet their banking requirements, whereas people from rural and semi-urban areas are not much aware of the value-added services.
Comparison of Selected Multiple Imputation Methods for Continuous Variables – Preliminary Simulation Study Results
Authors: Misztal Małgorzata Aleksandra
Published: February 2019

The problem of incomplete data and its implications for drawing valid conclusions from statistical analyses is not related to any particular scientific domain, it arises in economics, sociology, education, behavioural sciences or medicine. Almost all standard statistical methods presume that every object has information on every variable to be included in the analysis and the typical approach to missing data is simply to delete them. However, this leads to ineffective and biased analysis results and is not recommended in the literature. The state of the art technique for handling missing data is multiple imputation. In the paper, some selected multiple imputation methods were taken into account. Special attention was paid to using principal components analysis (PCA) as an imputation method. The goal of the study was to assess the quality of PCA‑based imputations as compared to two other multiple imputation techniques: multivariate imputation by chained equations (MICE) and missForest. The comparison was made by artificially simulating different proportions (10–50%) and mechanisms of missing data using 10 complete data sets from the UCI repository of machine learning databases. Then, missing values were imputed with the use of MICE, missForest and the PCA‑based method (MIPCA). The normalised root mean square error (NRMSE) was calculated as a measure of imputation accuracy. On the basis of the conducted analyses, missForest can be recommended as a multiple imputation method providing the lowest rates of imputation errors for all types of missingness. PCA‑based imputation does not perform well in terms of accuracy.
Modelowanie i prognozowanie procesów transmisji sygnałów między rynkami akcji. Analiza wpływu zmienności kursowej na giełdach w USA na rynek akcji w Polsce
Authors: Brzeszczyński Janusz
Published: February 2019

Efekty transmisji sygnałów między rynkami finansowymi na świecie, zarówno na poziomie zmienności kursowej, jak i kierunku (znaku) stóp zwrotu, są złożonymi zjawiskami, szczególnie w przypadku wykorzystania danych o wysokiej częstotliwości obserwacji. Artykuł prezentuje modele opisujące te procesy, wybrane kwestie metodologiczne, aplikację empiryczną dla polskiego rynku oraz wskazuje na możliwości wykorzystania omawianych narzędzi do budowy giełdowych strategii inwestycyjnych. Przeprowadzone badanie dla indeksu WIG20 na próbie z lat 2005–2016 dowodzi występowania związku między zmiennością stóp zwrotu indeksu WIG20 a stopami zwrotu indeksów giełdowych z rynku w USA, przy czym najsilniejsza zależność zidentyfikowana została w przypadku indeksu DJIA. Ponadto zaobserwowany został efekt ewolucji zmian wartości estymowanych parametrów w badanych modelach wraz z upływem czasu. Oszacowania parametrów z okresu próby z lat 2005–2016 wykorzystane zostały także w eksperymencie prognostycznym przy użyciu danych z roku 2017 z zastosowaniem dodatkowo kontraktów futures na indeks WIG20.

Different personality types are different in managing their emotions. Likewise, the type of introvert and extrovert personality, if extroverts tend to be ﬂexible and easy to socialize, introverts are not. Personal introverts that are identical with closed attitudes and lack of socialization. But some introverts develop emotions so they are able to adapt to the new environment, even though for that they need more time to reach that stage. This research is a type of library research or library research, using a reference analysis approach. Based on this research, introverted emotional intelligence is understanding the environment, planning approaches, doing what has been planned well, then evaluating the steps that have been taken. So that introverts have good emotional intelligence with a detailed process called relational understanding.
