Pre-service Teachers and Self-Efficacy: A Study in Contrast
Authors: Colson Tori , Sparks Kelly , Berridge Gina , Frimming Renee , Willis Clarissa 
Published: January 2018

AbstractWith increased emphasis on student achievement in schools, teacher education programs are challenged to meet the demand for highly effective teachers. Ensuring that pre-service teachers feel confident in their ability to teach, prompted one Midwestern University to implement an extended student teaching placement. The idea behind this endeavor was two fold; first to provide future teachers a more robust and diverse classroom experience; and secondly to provide more opportunities for students to get experience in high-risk school settings. There is very limited research on the impact of year-long student teaching on a teacher’s sense of efficacy. The purpose of this study was to compare the efficacy of teacher candidates placed in a year-long student teaching placement to teacher candidates placed in a traditional one semester (16 week) placement. All teacher candidates completed a 24 questionTeachers’ Sense of Efficacy Scaleas well as nine demographic questions. The survey developed at Ohio State University by Tschannen-Moran and Woolfolk Hoy (2001), measures teacher attitudes towards working with students, student engagement, instructional practices, and classroom management. Specifically, the questions represent essential tasks in teaching such as assessment, differentiating lessons for individual students, dealing with students with learning challenges, repairing student understanding, and encouraging student engagement and interest. The results of the study indicated that pre-service teacher candidates in a year-long student teaching placement were more satisfied with their ability to engage students and manage classroom behavior than their counterparts in a traditional one semester placement.

Authors: Jaser Miriam , Haug Stephan , Min Aleksey 
Published: January 2018

Abstract
In this paper, we propose a simple non-parametric goodness-of-fit test for elliptical copulas of any dimension. It is based on the equality of Kendall’s tau and Blomqvist’s beta for all bivariate margins. Nominal level and power of the proposed test are investigated in a Monte Carlo study. An empirical application illustrates our goodness-of-fit test at work.

The Trade Impacts of a Food Scare: The Fonterra Contamination Incident
Authors: Stojkov Katarina , Noy Ilan , Sağlam Yiğit 
Published: January 2018

Abstract
This paper examines the impact of a food contamination scare in the dairy sector on dairy exports. We investigate this question in the context of the 2013 Whey Protein Concentrate contamination incident in New Zealand. We assess the impact of this incident on dairy exports using synthetic control methods. A synthetic counterfactual scenario where the incident did not occur is developed using weighted information from other countries unaffected by the scare. We find that there was an initial negative shock to the exports of products that were thought to have been contaminated, but that there were no significant sustained impacts on other dairy products. The affected products made up only a small proportion of New Zealand dairy exports, with the vast majority of dairy exports being unaffected. Infant formula exports appear to have recovered more than a year after the scare. However, whey product exports (the contaminated product) remain lower than they otherwise would have been.
Therapeutic Angiogenesis for Severely Ischemic Limbs — from Bench to Bedside in Acute Vascular Care
Authors: Benedek Theodora , Kovács István , Benedek Imre 
Published: January 2018

Abstract
Severe limb ischemia represents a critical condition, being associated with high morbidity and mortality rates. Patients with critical limb ischemia (CLI) require urgent initiation of interventional or surgical treatment, as restoration of the blood flow is the only way to ensure limb salvage in these critical cases. At the same time, in acute limb ischemia, a dramatic form of sudden arterial occlusion of the lower limbs, the integrity of the limb is also seriously threatened in the absence of urgent revascularization. From patients with CLI, 40% are “no option CLI”, meaning patients in whom, due to anatomical considerations or to the severity of the lesions, there is no possibility to perform interventional or surgical treatment or they have failed. Therapeutic angiogenesis has been proposed to serve as an effective and promising alternative therapy for patients with severe limb ischemia who do not have any other option for revascularization. This review aims to present the current status in therapeutic angiogenesis and the role of different approaches (gene or cell therapy, intra-arterial vs. intramuscular injections, different sources of cells) in increasing the rates of limb salvage in patients with severe ischemia of the lower limbs.
Similarity of Changes in Average Prices of Residential Properties in Europe in 2010-2016
Authors: Dittmann Iwona 
Published: January 2018

Abstract
The aim of the article was to assess the similarities of average price changes in the residential market in 34 European countries in 2010-2016. The first part of the study concerned tendencies of changes in average prices in residential markets in the studied countries, while the second part analyzed co-occurrence of changes in these countries in time. The study covered the period after the first wave of the financial crisis in Europe and took into account the second wave of crisis in several euro area countries. Price indices, trend functions, price ranges, linear correlation coefficients and shape similarity measure were utilized for conducting this study.
European countries, in general, differed with respect to changes in prices in the residential market. 12 countries were characterized by a trend of increasing price indices. 18 countries were classified as correcting countries, as during the studied period they were distinguished by a clear change in trend. Four countries with a downward trend during the study period were also identified. Furthermore, a differentiation between the countries was found due to the values of price ranges during the studied period. Studies of co-occurrence in time were conducted with the use of linear correlation coefficients mainly for groups of rising countries and falling countries. The study was conducted using measures of shape similarity, which allowed for an identification of converging, leading and following markets for some countries.
Assembling a Cellular User Manual for the Brain
Authors: Sloan Steven A. , Barres Ben A. 
Published: January 2018

For many years, efforts to decipher the various cellular components that comprise the CNS were stymied by a lack of technical strategies for isolating and profiling the brain's resident cell types. The advent of transcriptional profiling, combined with powerful new purification schemes, changed this reality and transformed our understanding of the macroglial populations within the brain. Here, we chronicle the historical context and scientific setting for our efforts to transcriptionally profile neurons, astrocytes, and oligodendrocytes, and highlight some of the profound discoveries that were cultivated by these data.Following a lengthy battle with pancreatic cancer, Ben Barres passed away during the writing of this Progression piece. Among Ben's innumerable contributions to the greater scientific community, his addition of publicly available transcriptome databases of CNS cell types will forever remain a relic of his generous spirit and boundless scientific curiosity. Although he had impressively committed a majority of these enormous gene lists to memory, Ben could oftentimes be spotted at meetings buried in his cell phone on the Barres RNAseq database. Perhaps the only thing he enjoyed more than exploring these data himself, was knowing how useful these contributions had been (and will hopefully continue to be) to his scientific peers.
Nutrient Removal during Stormwater Aquifer Storage and Recovery in an Anoxic Carbonate Aquifer

Published: January 2018

Stormwater harvesting coupled to managed aquifer recharge (MAR) provides a means to use the often wasted stormwater resource while also providing protection of the natural and built environment. Aquifers can act as a treatment barrier within a multiple‐barrier approach to harvest and use urban stormwater. However, it remains challenging to assess the treatment performance of a MAR scheme due to the heterogeneity of aquifers and MAR operations, which in turn influences water treatment processes. This study uses a probabilistic method to evaluate aquifer treatment performance based on the removal of total organic C (TOC), N, and P during MAR with urban stormwater in an anoxic carbonate aquifer. Total organic C, N, and P are represented as stochastic variables and described by probability density functions (PDFs) for the “injectant” and “recovery”; these injectant and recovery PDFs are used to derive a theoretical MAR removal efficiency PDF. Four long‐term MAR sites targeting one of two tertiary carbonate aquifers (T1 and T2) were used to describe the nutrient removal efficiencies. Removal of TOC and total N (TN) was dominated by redox processes, with median removal of TOC between 50 and 60% at all sites and TN from 40 to 50% at three sites with no change at the fourth. Total P removal due to filtration and sorption accounted for median removal of 29 to 53%. Thus, the statistical method was able to characterize the capacity of the anoxic carbonate aquifer treatment barrier for nutrient removal, which highlights that aquifers can be an effective long‐term natural treatment option for management of water quality, as well as storage of urban stormwater.Core Ideas
Aquifer treatment capacity for C, N, and P was quantified in four long‐term ASR sites.
Robust median TOC removal was 50 to 60% in an anoxic carbonate aquifer.
Median TN removal was at least 40% at three sites and inhibited by pH >8 at a fourth.
TP removal was 29 to 53%; however, sorption capacity may be limited.

AbstractThermal springs are natural environments present all over the world and their use represents a social-economical resource with an impact on sanus per aquam (SPA) medical and wellness applications. Physical-chemical and microbiological balances characterize these ecological niches and their knowledge is essential to define water properties and support appropriate management. This study is a pilot application of a larger research project, involving metagenomics and aimed to fingerprint springs and map SPA biodiversity. Waters and their deposits were collected in six thermal springs from the Lazio region in Italy. The phylogenic microbial profiles performed by Next Generation Sequencing (NGS) analysis showed a clear separation between different springs. Statistical analyses revealed correlations between the abundance of specific bacteria and environmental variables. Temperature, Sodium and H2S levels appear to play a key role in influencing the microbiota. The extension of this model to other springs will contribute to characterize and map the microbial community in thermal springs, allowing associations with chemical-physical factors. Biodiversity is a still underestimated property of thermal springs and a key element in several SPA applications. The Atlas progress is shedding light on biotic and abiotic components in these ecological niches, opening further perspectives for supporting appropriate use and management of thermal waters.

Published: January 2018

Abstract
The Sustainable Development Goals concept advocates affordable, safe and clean water supply. The water shortage in Dar es Salaam city affects communities in different wards of Kinondoni municipality. As a strategy to improve water access, this study assessed opportunities for application of rainwater harvesting (RWH) technologies, communities’ knowledge of this and their willingness to adopt RWH technologies, and challenges for installation and maintenance of RWH technologies in areas of Makongo, Mbezi, Msasani and Kimara wards of Kinondoni municipality. Data collection involved interviews, questionnaires and observation while the SPSS tool was used for data analysis. Also, laboratory tests for water quality parameters were conducted. Results showed that rooftop RWH systems with proper components and proper maintenance were found to provide better quality water for domestic use than other sources. Laboratory tests revealed that rainwater was better than other water sources. Lack of knowledge was the main factor that hindered adoption of RWH technology. Also, initial investment cost was among the reasons deterring its adoption. Therefore, to improve the adoption rate of RWH technologies there should be an integrated participation of different stakeholders to educate and support communities to address RWH technologies’ challenges. This can be supported by a proposed institutional framework.

Published: January 2018

Este trabalho tem por objetivo favorecer a aprendizagem significativa de alunos do 6º ano do ensino fundamental quanto ao conceito do ensino de perímetro. Nosso aporte teórico está pautado na teoria da aprendizagem significativa proposta por David Ausubel, na qual tem o intuito de auxiliar o professor a tornar suas aulas mais atrativas, ou seja, menos mecânicas. Além disto, serve como aporte para que professor possa organizar suas aulas e identificar os conhecimentos prévios dos alunos percebendo as lacunas existentes de conhecimentos que os alunos possuem, mediante um conteúdo. Abordamos uma metodologia qualitativa com caráter exploratório. Participaram deste trabalho 32 alunos do 6º ano do Ensino Fundamental de uma escola pública situada no Município de São Vicente Férrer/PE. Neste trabalho, utilizamos uma oficina denominada:, o tangram: aprendendo perímetro por meio de um jogo matemático. Esta vivência foi mediada por meio de dois momentos. A primeira a partir de maneira teórica respaldando-se na explicação do conceito de perímetro. Já no segundo momento nos detemos na explicação das regras do jogo tangram (Modelo Tradicional Chinês), realizando nesta etapa um exercício contemplando seis questões. De acordo com as discussões em sala de aula com os alunos referente ao conceito de perímetro notamos que aconteceu indícios de uma aprendizagem significativa. A princípio apenas 4 alunos de uma turma composta por 32 alunos concebiam conhecimentos prévios quanto ao conceito de perímetro. Desta forma, trabalhamos a oficina para oportunizar uma aprendizagem significativa no conceito de perímetro que por sua vez significa a soma dos contornos das figuras. Diante de nossas análises, podemos verificar que houve avanços de conhecimentos nos 4 alunos que detinham conhecimentos prévios quanto o conceito de perímetro. E, aqueles que não apresentaram definições do conteúdo também evoluíram no que se refere ao estudo do conceito do perímetro. Enfatizamos que o jogo tangram foi utilizado como um material potencialmente significativo no processo de ensino e aprendizagem como meio de facilitar a compreensão e percepção dos alunos frente ao novo conhecimento matemático. Portanto, ressaltamos que a aprendizagem significativa ocorreu o que se refere ao estudo do conceito de perímetro.
Impact Response of Base Isolated Building with Adjacent Structures
Authors: Shinde Niraj , Soni Devesh 
Published: January 2018

The seismic behavior of multi-storied building supported on Friction pendulum system (FPS) during impact with adjacent structure is examined. One lateral degree of freedom is considered at each floor, base mass and slider. Adjacent structure (i.e. retaining walls or entry bridges) is modeled as an impact element in form of spring and dashpot. The impact response of FPS bearing is studied under 60 records consisting of service level, design basis and maximum credible earthquakes. Newmark’s step by step iteration method is used to solve the differential equations of motion for the isolated system. The impact response of isolated building is studied under the variation of important system parameters such as size of gap and stiffness of impact element. To reduce the influence of impact a viscous damper is employed between the isolated building and adjacent structure. It is concluded that during impact with adjacent structure the superstructure acceleration and base shear increases while bearing displacement decreases. The employment of viscous damper shows considerable reduction in bearing displacements, base shear and impact force during DBE and MCE events. Further, the effects of impact are found critical if the superstructure is flexible and greater stiffness of impact element. The top floor acceleration increases with the isolation gap up to certain limit and again reduces with the increase in isolation gap.Keywords - Adjacent Structure; isolation; Sliding bearing; Viscous Damper; Gap effect; Floor acceleration; Impact
Consideraciones morfológicas en torno a la terminología del sector turístico aplicado a la lengua alemana con fines específicos
Authors: Burgos Cuadrillero Beatriz 
Published: January 2018

Bajo el techo de la lexicología es indiscutible la interrelación que se establece entre la morfología con la sintaxis y la semántica. En este sentido, el fenómeno de la formación de palabras ocupa siempre un importante lugar en la investigación lexicológica ya que genera modelos estables, es decir, nuevas formaciones de palabras tomando como punto de partida morfemas libres. Este hecho cobra especial importancia en una lengua como el alemán donde existen en torno a medio millón de palabras de las cuales unas pocas miles son palabras originales (cfr. Götze/Hess–Lüttich) y el resto se han obtenido mediante el proceso de composición o a través de otros recursos morfológicos, de los cuales el más frecuente es la derivación. De tal manera que su estudio cobra plenamente sentido en el caso de las creaciones ad hoc.La presente comunicación tiene por objeto realizar un análisis, desde el punto de vista morfológico, de la terminología en el sector turístico con la finalidad de descubrir el rol que desempeña la morfología léxica, estudio lingüístico que aplicaremos a la lengua alemana ya que los diferentes procesos de formación de palabras juegan el papel más importante en la ampliación del vocabulario de una lengua y, en lo que al alemán se refiere, este fenómeno es el ejemplo más claro de creatividad lingüística.

In the production of Self Compacting concrete (SCC), the use of quaternary blend of supplementary cementitious materials (SCM’s) has not found enough applications. For this purpose, an effort has been done to present a mix design for M60 grade and M80 grade SCC with quaternary blending of fly ash(FA), ground granulated blast furnace slag (GGBS), silica fume (SF) in accordance with EFNARC guidelines. Findings: In this study, cement has been replaced with SCM’s from 30% to 50%. Fresh properties of concrete were tested for slump flow, T50 test and U box. The hardened properties of concrete were tested for compressive strength and durability. The tests were performed for 7, 28, 56 and 91 days. The results indicate that the use of quaternary blend has improved the workability, compressive strength and durability properties of specimens than the control specimen. Application: The primary contribution is to fill the congestedreinforcement and increase the durability and life span of the structure.
Academic Discourse in English Medium Instruction Contexts: A Look at Teacher Explanations
Authors: Martín-Del-Pozo María Ángeles 
Published: January 2018

Teaching and learning content subjects through English requires a competence in academic language which Cummins (1984) labeled CALP (Cognitive Academic Language Proficiency). Revisiting this concept could shed light on the academic language skills necessary for communication in bilingual classrooms. A first step in this long journey could be a deeper comprehension of the academic linguistic or cognitive discourse functions (Dalton-Puffer, 2013). This paper approaches the function of explaining.To accomplish this aim, six lecturers teaching through English at Escuela de Ingeniería de Informática (Segovia, Spain) were videotaped. Lessons were transcribed to create a corpus. The main research questions followed Dalton-Puffer´s (2007) model for a secondary education context:1.	How many occurrences of the academic function of explanation are there in the corpus?2.	What is the linguistic form of these explanations?3.	Is there any signaling language or metalanguage around them?The seventy explanation fragments found were classified in three categories following Brown´s taxonomy (2006).•	Interpretative explanations respond to the question ‘What?’ and are very close to definitions.•	Descriptive explanations respond to the question ‘How?’ and centre on processes, structures and procedure.•	Reason giving explanations respond to the question ‘Why?’ and provide reasons and causes.The findings show a rich frequency of this academic function in contrast to the very limited comparable previous studies in bilingual classrooms (Dalton-Puffer, 2007). Bar graphs of frequencies and distribution of types per lecturer are presented. Regarding qualitative aspects, the samples found offer insights about how explaining is performed in bilingual content lectures. The form of these explanations and the metalanguage signaling them are analyzed and illustrated with numerous examples from the corpus.Taking as starting point the description of the explanations present in lecturer discourse some reflections about their potential for the learning of content and language are provided. The conclusions section suggests some pedagogical implications for the linguistic education of both students and lecturers in English medium instruction environments.
