Intellectual Capital Reporting and Disclosure Practices in Sri Lanka
Authors: Gunawardana Kennedy D.
Published: September 2019

This chapter examines disclosure practices of intellectual capital in the Sri Lankan context. The chapter provides an empirical analysis to showcase the relationship between intellectual capital reporting and the management perception. The three capital components identified in the intellectual capital are human capital, organizational capital, and social capital. Those capitals give a considerable contribution on the wealth of the organization and the main problem is the subjectivity and complexity of the disclosure practices of the listed companies in Colombo Stock Exchange from 2013 – 2016. This study is based on the intellectual capital disclosure practices published in annual reports for the period of 3 years. The managerial perception and company characteristics were linked with the intellectual capital disclosure practices. The study found no common procedure for disclosure among the annual reports while the details of intellectual capital disclosures vary considerably from one annual report to another.
Electromagnetic Metamaterials in Microwave Regime
Authors: Sim Man Seng , You Kok Yeow , Esa Fahmiruddin
Published: September 2019

Metamaterials are artificially-engineered materials which possess unique properties not found in natural materials. The properties are derived from the structural designs of metamaterials and they allow the structure to manipulate electromagnetic waves and achieve desired responses in a certain frequency range. This chapter reviews past achievements, recent developments, and future trends on electromagnetic metamaterials in microwave regime. The chapter first briefly introduces electromagnetic metamaterials from a general prospect including the definition, historical overview, and classification of metamaterials. Furthermore, three selected applications of metamaterials which are microwave absorbers, sensors, and energy harvesters are discussed based on their operation principles, designs, and characteristics.
Solar Micro-Inverter

Published: September 2019

A solar micro inverter is a small-size inverter designed for single solar PV module instead of group of solar PV modules. Each module is equipped with a micro inverter to convert the DC electricity into AC electricity and the micro inverter is placed/installed below the module. The advantages of micro inverters are: reduced effect of shading losses, module degradation and soiling losses, enabled module independence, different rating of micro inverter can be connected in parallel to achieve the desired capacity, additional modules can be included at time which allows the good scalability, string design and sizing are avoided, failure of any micro inverter does not affect the overall power generation, individual MPPT controller for each module increases the power generation, any orientation and tilt angle allows higher design flexibility, lower DC voltage increasing the safety, easy to design, handle and install, requires less maintenance, draws attention of design engineers, contractors, etc.
Blogging as Online Reflection During Student Teaching
Authors: Collet Vicki Stewart
Published: September 2019

One of the most vital forms of dialogue for a novice teacher is the inner dialogue of reflective practice. Reflection is an evidence-based practice that improves instruction during preservice teachers' practicum experiences. While student teaching, preservice teachers may be so caught up in implementing lessons that they are unable to reflect in action; therefore, reflection-on-action, which occurs after teaching episodes, is critical. This study explores use of blogs as tools for reflection during the student-teaching experience, finding that blogs serve as a means of both self-expression and reflection. Additionally, the study suggests that self-questioning may lead to deeper reflection, and that preservice teachers should balance the articulation of emotions with specific descriptions of teaching and judgments about student learning in order to support reflection that leads to increased professional knowledge.
Training Novice Literacy Coaches Through a Coaching Rounds Framework
Authors: Massey Susan L. , Ortmann Lisa , Brodeur Katherine
Published: September 2019

Teacher preparation programs are responsible for training literacy specialists/literacy coaches to be effective teacher leaders. To do this, graduate student candidates need scaffolded experiences in working with adult learners as novice coaches. As part of an online capstone coaching course, researchers at two universities implemented a Coaching Rounds Framework to train novice coaches in using coaching language and coaching stances in authentic coaching experiences with class peers and teacher colleagues. Results indicate that by using a Gradual Release of Responsibility model in which candidates view exemplar coaching videos, rehearse coaching conversations with class peers, and analyze their authentic coaching conversations with teacher colleagues, candidates effectively support teachers in literacy instruction and engage in reflective practices.
Community of Digital Learners
Authors: Baker Elizabeth (Betsy) A.
Published: September 2019

This study resides at the intersection of digital literacies (ILA Standard 5) and communities of learners (evidence-based practice). An examination of self-studies and awards packets collected during 14 years of online teaching indicated that the instructor intentionally sought to harness online tools to support the formation and development of communities of learners. Of particular interest were the use of robust introductions, small group discussions, and authentic assessments. Similarities were evident between literature that describes offline communities of learners and the online communities forged in these courses. This study indicated that online teacher education courses that embrace social learning theories may be fertile ground for additional research. As education extends into online venues, such research is needed.
Stiffness and echogenicity: Development of a stiffness-echogenicity matrix for clinical problem solving
Authors: Stecco Antonio , Pirri Carmelo , De Caro Raffaele , Raghavan Preeti
Published: September 2019

The assessment of soft tissue stiffness is important to evaluate many neuromusculoskeletal conditions. Several tools have been proposed for the assessment of stiffness, but ultrasonography appears to be most practical. The reflection of ultrasound waves as it travels through tissue enables assessment of tissue echogenicity, which is influenced by the characteristics of the sound wave as well as the characteristics of the tissue through which it passes, such as the amount of fat and fibrous tissue. However, tissue stiffness is not directly proportional to its echogenicity. Hence evaluation of echogenicity, as a stand-alone technique, is inadequate to describe its mechanical properties. The aim of this manuscript is to present a method of combining echogenicity evaluation by ultrasound and stiffness evaluation by palpation to better describe the mechanical properties of muscle using a stiffness-echogenicity matrix.
Noise attenuation provided by hedges

Published: September 2019

During the past few decades, urban areas have experienced increasing environmental stress. Noise is considered as one of the most important sources of urban pollution with adverse effects on human health. Urban vegetation provides many ecosystem services including the reduction of noise pollution. Hedges are widespread in cities and have the peculiarity of being often grown close to the source of noise. The study investigated the noise reduction due to hedges of Prunus laurocerasus and Laurus nobilis and the effect of the vegetation on sound spectra. Four different trials were carried out, including the use of two different noise sources and the measurement of noise at different distances both from the green barrier and from the noise source. During one trial, the influence of the type of ground surfaces between the noise source and the receiver was also evaluated. In the three trials where a significant attenuation of the noise occurred, the porosity of hedges measured less than 4.6% and an average noise reduction of about 2.7 dB(A) (max 7.0 dB(A)) was observed. This effect was particularly relevant in the range of higher frequencies (between 2 and 20 kHz). This study can contribute to plan and design hedges in the urban context.
Antecedents of psychological well-being among workers within small and medium enterprises
Authors: Maziriri Eugine T. , Chuchu Tinashe , Madinga Nkosivile W.
Published: September 2019

Orientation: In the contemporary business environment, employee mental health is neglected, especially in mental health research and practice in African Small and Medium-sized Enterprises (SMEs). This occurs even though this sector is the largest contributor to developed economies. This study highlights the importance of psychological well-being in SME performance and the individual employee.Research purpose: To investigate the influence of perceived organisational support, career goal development and empowering leadership on the psychological well-being of SME employees in Gauteng province, South Africa.Motivation for the study: Despite increasing research on SMEs, few studies have investigated the impact of perceived organisational support, career goal development, and empowering leadership on psychological well-being in a Southern African context.Research approach/design and method: This study followed a quantitative approach, using the survey methodology where a structured questionnaire was administered to 250 SME employees. To evaluate the psychometric properties of measurement scales, a confirmatory factor analysis was performed. Structural equation modelling was used to test the hypotheses.Main findings: Perceived organisational support, career goal development and empowering leadership have a positive and significant impact on the psychological well-being of SME workers. A robust, positive and significant relationship exists between empowering leadership and psychological well-being.Practical/managerial implications: The results indicate that SME managers in South Africa should pay more attention to, or place greater emphasis on, supporting employees in their organisations, recognising and assisting them in achieving their goals, and empowering them to be happy at work. If the psychological well-being of employees is prioritised, SME business performance will ultimately improve.Contribution/value-add: This study contributes to the current body of Africa’s industrial psychology and mental health literature – a field that has received little research attention in developing countries like South Africa.
The index of generalised Dirac–Schrödinger operators
Authors: van den Dungen Koen
Published: September 2019

We study the relation between spectral flow and index theory within the framework of (unbounded)

K

K-theory. In particular, we consider a generalised notion of ‘Dirac–Schrödinger operators’, consisting of a self-adjoint elliptic first-order differential operator

\mathcal D

with a skew-adjoint ‘potential’ given by a (suitable) family of unbounded operators on an auxiliary Hilbert module. We show that such Dirac–Schrödinger operators are Fredholm, and we prove a relative index theorem for these operators (which allows cutting and pasting of the underlying manifolds). Furthermore, we show that the index of a Dirac–Schrödinger operator represents the pairing (Kasparov product) of the

K

-theory class of the potential with the

K

-homology class of

\mathcal D

. We prove this result without assuming that the potential is differentiable; instead, we assume that the ‘variation’ of the potential is sufficiently small near infinity. In the special case of the real line, we recover the well-known equality of the index with the spectral flow of the potential.

Norma Padrão, Norma Culta e Hibridismo Linguístico em Traduções de Artigos do New York Times
Authors: Amorim Lauro Maia , Di Santi Bianca Trindade
Published: September 2019

Este artigo traz resultados de uma pesquisa envolvendo um estudo sobre normas linguísticas híbridas em artigos jornalísticos do New York Times, traduzidos, para o português, e veiculados no site UOL. Segundo Faraco (2008) e Bagno (2012), há uma diferença entre a norma padrão e a norma culta, sendo a primeira aquela que reúne regras que prescrevem formas linguísticas a serem seguidas de acordo com um modelo idealizado de língua, mas difícil de ser seguido pela maioria dos usuários; e a segunda, aquela que reúne o conjunto de formas linguísticas que são, de fato, empregadas por muitos escreventes, sendo, portanto, mais acessíveis intuitivamente, embora não aceitas pela tradição gramatical conservadora representada pela norma padrão, comumente divulgada em compêndios gramaticais e manuais de estilo.  Pretende-se avaliar se seria possível afirmar que textos jornalísticos traduzidos do inglês, semelhante ao que já comprovadamente ocorre com textos jornalísticos originalmente escritos em português, são igualmente permeáveis a formas linguísticas não abonadas pela norma padrão.
A Valoração nas Sentenças com Adjuntos Modais do Conto “Grace”, de Joyce, e de duas de suas Reinstanciações para o Português do Brasil
Authors: Rodrigues Roberta Rego
Published: September 2019

A Valoração é um sistema semântico-discursivo interpessoal que prevê significados de Atitude, Comprometimento e Gradação (MARTIN; WHITE, 2005). Este artigo tem por objetivo investigar de forma geral os três sistemas valorativos nas sentenças com Adjuntos Modais do conto “Grace”, de James Joyce (2001), e em duas Reinstanciações para o português do Brasil, uma feita por José Roberto O’Shea (JOYCE, 2012) e a outra produzida por Guilherme da Silva Braga (JOYCE, 2013). Foi utilizada uma planilha eletrônica com três abas para a classificação e a quantificação de dados. Os resultados mostram que os Adjuntos Modais são importantes para a identificação de significados valorativos. Pode-se concluir que as categorias mais frequentes nos contos são Julgamento, Heteroglossia e Força.
Homeward Bound Translingualism: (Re)Translating Dai Sijie’s Autonarration
Authors: Codeluppi Martina
Published: September 2019

Os autores migrantes que escrevem em idiomas estrangeiros são um dos efeitos mais tangíveis da globalização da literatura chinesa contemporânea em curso hoje em dia. Dai Sijie, escritor e realizador migrante chinês, escolheu o Francês para expressar sua narração da China. Em breve elese tornou um exemplo de como a presença de várias culturas dentro de um indivíduo pode se tornar uma auto-hibridação. Seu primeiro romance Balzac et la Petite Tailleuse chinoise (2000) baseia-se na experiência de Dai Sijie de banimento e conta a história de dois jovens cuja reeducação foifortemente influenciada por Romances ocidentais proibidos na China. Mas o que acontece quando um texto literário nascido como um trabalho translingual e transcultural é traduzido de volta no seu idioma (e cultura) de origem? A mediação se realiza duas vezes ou é anulada? Como esse processo influencia a representação do autor? O presente artigo responderá a essas perguntas através de uma análise comparativa entre a história e suas versões em chinês (publicado no P.R.C. e Taiwan), concentrando-se nas (re) traduções linguísticas e culturais. A “febre da literatura mundial” enfatiza a força centrífuga que empurra a literatura da China para o Ocidente, mas a globalização é um movimento circular que às vezes implica a volta para casa de uma literaridade chinesa “à prova deoeste”.

Tessa Dwyer Speaking in subtitles. A reavaliação da tradução de tela trata principalmente da idéia de "errância" na tradução audiovisual, especialmente na legendagem. O livro é dividido em duas partes, e cada uma dessas partes subdividida em três capítulos. Antes de ler este livro, parecia que eu estava fazer uma viagem de inúmeras terminologias relacionadas ao campo da tradução, mas o autor consegue mostrar alguns fatos interessantes sobre a evolução do que era apenas uma prática de tradutores em uma área acadêmica cheia de sutilezas. Estudos como as noções de fidelidade e respeito ao texto original. Através desse debate, a autora questiona a noção do que deve ser considerado certo ou errado na tradução. Ela tenta desconstruir o chamado caminho certo para traduzir um produto audiovisual, introduzindo a idéia de “errância” e quão inevitável pode ser em algumas formas de tradução audiovisual, como “fan subtbing”, uma maneira clandestina e ilegal criar legendas, e algumas vezes consideradas inferiores às legendas oficiais produzidas pelos tradutores, mas uma ferramenta poderosa para tornar os produtos audiovisuais acessíveis ao público que não conhece uma língua estrangeira.
Incongruent Court Advice: Examining Fair Value and Fair Market Value Standards in Commercial Damage Cases Pursuant to Minority Claims
Authors: Young Christopher , Janos James
Published: September 2019

The standard of value in shareholder oppression and dissolution cases for a valuation of a minority shareholder's interest in a business in most U.S. states is fair value. The fair value standard in most U.S. states excludes discounts for control and lack of marketability. However, the three valuation approaches commonly used (income, market, and asset) all yield different levels of value. Consequently, this can unfairly negatively or positively impact minority and oppressed shareholders. In this paper we examine these inconsistencies and offer a solution to arriving at a level of value the trier of fact is seeking to obtain.
Rapid transition in winter aerosol composition in Beijing from 2014 to 2017: response to clean air actions
Authors: Li Haiyan , Cheng Jing , Zhang Qiang , Zheng Bo , Zhang Yuxuan , Zheng Guangjie , He Kebin
Published: September 2019

Abstract. The clean air actions implemented by the Chinese
government in 2013 have led to significantly improved air quality in
Beijing. In this work, we combined the in situ measurements of the chemical
components of submicron particles (PM1) in Beijing during the winters
of 2014 and 2017 and a regional chemical transport model to investigate the
impact of clean air actions on aerosol chemistry and quantify the relative
contributions of anthropogenic emissions, meteorological conditions, and
regional transport to the changes in aerosol chemical composition from 2014
to 2017. We found that the average PM1 concentration in winter in
Beijing decreased by 49.5 % from 2014 to 2017 (from 66.2
to 33.4 µg m−3). Sulfate exhibited a much larger decline than
nitrate and ammonium, which led to a rapid transition from sulfate-driven to
nitrate-driven aerosol pollution during the wintertime. Organic aerosol
(OA), especially coal combustion OA, and black carbon also showed large
decreasing rates, indicating the effective emission control of coal
combustion and biomass burning. The decreased sulfate contribution and
increased nitrate fraction were highly consistent with the much faster
emission reductions in sulfur dioxide (SO2) due to phasing out coal in
Beijing compared to reduction in nitrogen oxides emissions estimated by
bottom-up inventory. The chemical transport model simulations with these
emission estimates reproduced the relative changes in aerosol composition
and suggested that the reduced emissions in Beijing and its surrounding
regions played a dominant role. The variations in meteorological conditions
and regional transport contributed much less to the changes in aerosol
concentration and its chemical composition during 2014–2017 compared to the
decreasing emissions. Finally, we speculated that changes in precursor
emissions possibly altered the aerosol formation mechanisms based on ambient
observations. The observed explosive growth of sulfate at a relative
humidity (RH) greater than 50 % in 2014 was delayed to a higher RH of
70 % in 2017, which was likely caused by the suppressed sulfate formation
through heterogeneous reactions due to the decrease in SO2 emissions.
Thermodynamic simulations showed that the decreased sulfate and nitrate
concentrations have lowered the aerosol water content, particle acidity, and
ammonium particle fraction. The results in this study demonstrate the
response of aerosol chemistry to the stringent clean air actions and
identify that the anthropogenic emission reductions are a major driver,
which could help to further guide air pollution control strategies in China.
Vertical profile observations of water vapor deuterium excess in the lower troposphere
Authors: Salmon Olivia E. , Welp Lisa R. , Baldwin Michael E. , Hajny Kristian D. , Stirm Brian H. , Shepson Paul B.
Published: September 2019

Abstract. We use airborne measurements of water vapor
(H2Ov) stable isotopologues and complementary meteorological
observations to examine how boundary layer (BL) dynamics, cloud processing, and
atmospheric mixing influence the vertical structure of δD, δ18O, and deuterium excess (d excess =δD–8×δ18O) in the BL, inversion layer (INV), and lower free
troposphere (FT). Flights were conducted around two continental US cities in
February–March 2016 and included vertical profiles extending from near
the surface to ≤2 km. We examine observations from three unique case
study flights in detail. One case study shows observations that are
consistent with Rayleigh isotopic distillation theory coinciding with clear
skies, dry adiabatic lapse rates within the boundary layer, and relatively
constant vertical profiles of wind speed and wind direction. This suggests
that the air mass retained the isotopic fingerprint of dehydration during
moist adiabatic processes upwind of the study area. Also, observed d-excess
values in the free troposphere were sometimes larger than Rayleigh theory
predicts, which may indicate mixing of extremely dehydrated air from higher
altitudes. The two remaining case studies show isotopic anomalies in the
d-excess signature relative to Rayleigh theory and indicate cloud processes
and complex boundary layer development. The most notable case study with
stratocumulus clouds present had extremely low (negative) d-excess values at
the interface of the inversion layer and the free troposphere, which is
possibly indicative of cloud or rain droplet evaporation. We discuss how in situ
H2Ov stable isotope measurements, and d excess in particular,
could be useful for improving our understanding of water phase changes,
transport, and mixing that occurs between the BL, INV, and FT.
Cushion bogs are stronger carbon dioxide net sinks than moss-dominated bogs as revealed by eddy covariance measurements on Tierra del Fuego, Argentina
Authors: Holl David , Pancotto Verónica , Heger Adrian , Camargo Sergio Jose , Kutzbach Lars
Published: September 2019

Abstract. The near-pristine bog ecosystems of Tierra del Fuego in southernmost Patagonia have so far not been studied in terms of their current carbon dioxide (CO2) sink strength. CO2 flux data from Southern Hemisphere peatlands are scarce in general. In this study, we present CO2 net ecosystem exchange (NEE) fluxes from two Fuegian bog ecosystems with contrasting vegetation communities. One site is located in a glaciogenic valley and developed as a peat moss-dominated raised bog, and the other site is a vascular plant-dominated cushion bog located at the coast of the Beagle Channel. We measured NEE fluxes with two identical eddy covariance (EC) setups at both sites for more than 2 years. With the EC method, we were able to observe NEE fluxes on an ecosystem level and at high temporal resolution. Using a mechanistic modeling approach, we estimated daily NEE models to gap fill and partition the half-hourly net CO2 fluxes into components related to photosynthetic uptake (gross primary production, GPP) and to total ecosystem respiration (TER). We found a larger relative variability of annual NEE sums between both years at the moss-dominated site. A warm and dry first year led to comparably high TER sums. Photosynthesis was also promoted by warmer conditions but less strongly than TER with respect to absolute and relative GPP changes. The annual NEE carbon (C) uptake was more than 3 times smaller in the warm year. Close to the sea at the cushion bog site, the mean temperature difference between both observed years was less pronounced, and TER stayed on similar levels. A higher amount of available radiation in the second observed year led to an increase in GPP (5 %) and NEE (35 %) C uptake. The average annual NEE-C uptake of the cushion bog (-122±76 gm-2a-1, n=2) was more than 4 times larger than the average uptake of the moss-dominated bog (-27±28 gm-2a-1, n=2).

Abstract. Forest soils represent a major stock of organic carbon (C) in the terrestrial biosphere, but the dynamics of soil organic carbon (SOC) stock are poorly quantified, especially based on direct field measurements. In this study, we investigated the 20-year changes in the SOC stocks at eight sites from southern to northern China. The averaged SOC stocks increased from 125.2 ± 85.2 Mg C ha−1 in the 1990s to 133.6 ± 83.1 Mg C ha−1 in the 2010s across the forest sites, with a mean increase of 127–908 kg C ha−1 yr−1. This SOC accumulation was resulted primarily from both leaf litter and fallen logs and equivalent to 3.6–16.3 % of aboveground net primary production. Our findings provide strong evidence that China's forest soils have been acting as significant carbon sinks although their strength varies with forests in different climates.
Reconstructions of Droughts in Germany since 1500
Authors: Glaser Rüdiger , Kahle Michael
Published: September 2019

Abstract. The present article deals with the reconstruction of drought time series in Germany since 1500. The reconstructions are based on written records from the historical climate and environmental database tambora.org, early and official instrument data as well as precipitation and temperature indices. From the historical descriptions of the weather climatic processes and their effects and consequences for the environment and society, action paths and drought categories are derived. Furthermore, a historical precipitation index (HPI) is calculated and correlated with the SPI index. These are correlated and quantified in a rating scheme with modern rainfall indices and recent drought categories. Finally, a Historical Drought Index (HDI) and a Historical Wet Index (HWI) derived from the hygric indices are presented. On this basis, the long-term development of dryness and drought and significant accumulations and extremes in Germany since 1500 are discussed.
Precipitation transition regions over the southern Canadian Cordillera during January–April 2010 and under a pseudo-global-warming assumption
Authors: Almonte Juris D. , Stewart Ronald E.
Published: September 2019

Abstract. The occurrence of various types of winter precipitation
is an important issue over the southern Canadian Cordillera. This issue is
examined from January to April of 2010 by exploiting the high-resolution
Weather Research and Forecasting (WRF) model Version 3.4.1 dataset that was
used to simulate both a historical reanalysis-driven (control – CTRL) and a
pseudo-global-warming (PGW) experiment (Liu et al., 2016). Transition
regions, consisting of both liquid and solid precipitation or liquid
precipitation below 0 ∘C, occurred on 93 % and 94 % of the
days in the present and PGW future, respectively. This led to accumulated
precipitation within the transition region increasing by 27 % and was
associated with a rise in its average elevation by 374 m over the Coast Mountains and
Insular Mountains and by 240 m over the Rocky Mountains and consequently to
an eastward shift towards the higher terrain of the Rocky Mountains.
Transition regions comprised of only rain and snow were most common under
both the CTRL and PGW simulations, although all seven transition region
categories occurred. Transition region changes would enhance some of the
factors leading to avalanches and would also impact ski resort operations.
QUANTITATIVE COMPARISON BETWEEN NEURAL NETWORK- AND SGM-BASED STEREO MATCHING
Authors: Frenzel A. , Deckers N. , Reulke R.
Published: September 2019

Abstract. Over the last decades, various methods for three-dimensional detection of the environment have been developed and successfully used. This work considers classical stereo methods, which can determine depth information by the means of correspondence analysis on the basis of two pictures of a scene. Recently, neural networks have been used to solve correspondence analysis. These procedures came first places on corresponding benchmarks and are ahead of many already established solutions. In this work, images captured by the ZED camera are evaluated for accuracy of the depth maps generated by several approaches. This includes modern methods based on neural networks.

Authors: Kuc G. , Chormański J.
Published: September 2019

Abstract. Nowadays there is need to take the action to find out the innovative solutions to reduce the negative effects of climate change in urban areas. Cities face multiple challenges in water management and flood protection at local scale, especially given an uncertain future climate and a rapidly growing population. The density of impervious surfaces (roofs and pavement) is a key element in evaluating hydrologic processes and occurring the surface runoff – the major component of water cycle in urban catchment. Satellite imagery are powerful and up-to-date data for estimation human impact on urban space. It is also highlighted the possibility of using those results in urban development studies according to adaptation cities to climate change. The Copernicus SENTINEL constellation brings out the potential to provide high quality and free of charge satellites images that enable to estimate parameters related to urban structure and imperviousness. Multitemporal Sentinel-2 data are widely used to calculate the indices for urban sprawl. The normalized difference built-up index (NDBI) and normalized difference vegetation index (NDVI), indicators providing information on urban heat Island effect, are useful for change detection of imperviousness percentage in urban areas. The main objective of this research is fusion of multi-temporal and multi-resolution SENTINEL-2 MSI data for developing a new, innovative approach for improving water management in urban catchments at local scale provide valuable input data for hydrological model. The results obtained were compared by quantitative comparison with Imperviousness HRL of Copernicus Program, visual comparison with OpenStreetMap data as well as qualitative comparison with the high resolution Planet’s.

Abstract. LiDAR technology has revolutionized the area of 3D data acquisition. It is possible to obtain in a very fast and accurate way geometric and other information for a large area . Along with the development of design technology, LiDAR point clouds are often used to create inventory models of building objects and installations. This paper presents the possibilities of assessing LiDAR data for BIM modeling. The areas in which the assessment and description of obtained TLS data is important are presented. In addition to the attributes for assessing the quality of spatial data contained in the ISO 19157 standard, a density parameter was proposed. Examples of point clouds with different density for the architectural detail are presented in the final part of the work. For the attributes describing LiDAR data sets the levels of importance have been proposed for.
THE TEST FIELD FOR UAV ACCURACY ASSESSMENTS
Authors: Wiącek P. , Pyka K.
Published: September 2019

Abstract. Nowadays UAV photogrammetry becomes a common method for mapping and surveying. At the same time due to the increasing range of work carried out with UAV, the importance of final product accuracy increases. However to obtain survey-grade accuracy it is necessary to perform bundle adjustment processes that could be affected by multiple factors like unstable camera calibration, correlation between interior and exterior orientation and insufficient georeference information. One of the aims of the project was to prepare the terrestrial test field, which helps to obtain optimal decorrelation and allows to objectively assess the accuracy of the bundle adjustment in UAV application. During the project, two multi-variant flights over the test field were conducted. The flights were performed with a fixed-wing airframe equipped with PPK receiver on-board. Based on the conducted flights, many data sets have been prepared, which differ as follows: types of cameras, GSD, flight direction and georeferenced method.
DUACS DT2018: 25 years of reprocessed sea level altimetry products
Authors: Taburet Guillaume , Sanchez-Roman Antonio , Ballarotta Maxime , Pujol Marie-Isabelle , Legeais Jean-François , Fournier Florent , Faugere Yannice , Dibarboure Gerald
Published: September 2019

Abstract. For more than 20 years, the multi-satellite Data Unification and Altimeter Combination System (DUACS) has been providing near-real-time (NRT) and delayed-time (DT) altimetry products. DUACS datasets range from along-track measurements to multi-mission sea level anomaly (SLA) and absolute dynamic topography (ADT) maps. The DUACS DT2018 ensemble of products is the most recent and major release. For this, 25 years of altimeter data have been reprocessed and are available through the Copernicus Marine Environment Monitoring Service (CMEMS) and the Copernicus Climate Change Service (C3S). Several changes were implemented in DT2018 processing in order to improve
the product quality. New altimetry standards and geophysical corrections
were used, data selection was refined and optimal interpolation (OI)
parameters were reviewed for global and regional map generation. This paper describes the extensive assessment of DT2018 reprocessing. The
error budget associated with DT2018 products at global and regional scales
was defined and improvements on the previous version were quantified
(DT2014; Pujol et al., 2016). DT2018 mesoscale errors were estimated using
independent and in situ measurements. They have been reduced by nearly 3 % to 4 % for global and regional products compared to DT2014. This reduction is even greater in coastal areas (up to 10 %) where it is directly linked to the geophysical corrections applied to DT2018 processing. The conclusions are very similar concerning geostrophic currents, for which error was globally reduced by around 5 % and as much as 10 % in coastal areas.
Collaborative, Multi-perspective Historical Writing: The Explanatory Power of a Dialogical Framework
Authors: Ben-David Kolikant Yifat , Pollack Sarah
Published: September 2019

There is an increased interest within the history education community in introducing students to the multi-perspective and interpretative nature of history. When these educational goals are pursued within collaborative contexts, what are the relationships of individuals from conflicting groups with historical accounts that they produced as a group? How does the joint writing influence their historical understanding?  We analyzed the joint accounts produced by high-school Israeli students, Jews and Arab/Palestinians, who collaboratively investigated historical events related to the Israeli-Palestinian conflict. Employing a thematic analysis and a Bakhtinian-inspired discourse analysis, we found that the joint texts were constructed of themes from both in-groups’ perspectives. The students constructed a dialogic relationship between these themes, which enabled them to legitimize the other’s voice, yet keep the voices unmerged. Additionally, although they never abandoned their in-group narratives, the joint account reflected a new, multi-perspective historical meaning of the historical event.
Removing Barriers to Treatment: Evaluation of a Youth Suicide Prevention Program
Authors: Crepeau-Hobson Franci , Estes James
Published: September 2019

This study examined the effectiveness of a suicide prevention program that provides free and accessible counseling services to suicidal youth. Children and adolescents who underwent a suicide risk assessment at a Colorado school (n = 99) were referred for counseling through the Second Wind Fund (SWF), a non-profit organization dedicated to the prevention of youth suicide. Each of these clients presented with at least 1 barrier to treatment such as no or inadequate insurance or lack of transportation. Through SWF, clients received up to 12 counseling sessions at no charge. Clients ranged from 8 to 18 years of age. Of the 99 clients, 93 completed the Suicide Ideation Questionnaire-Junior (SIQ-Jr) at the beginning and end of treatment. Results indicated that SIQ-Jr scores were significantly lower at the end of treatment. Follow-up surveys were sent to referral sources at the end of the subsequent school year to examine longer-term effectiveness of SWF services. The majority of clients did not require any additional intervention and none went on to die by suicide. Study results indicate that the removal of financial and social barriers can increase access to and participation in treatment and reduce suicidal thoughts and behaviors. Implications for practice, including suicide risk assessment and outside referrals are discussed.
Bridging Families and Schools to Prevent Youth from Running Away From Home
Authors: Radu Monica Bixby
Published: September 2019

Running away from home is a serious problem among American youth. It has been linked to numerous negative social, psychological, and behavioral outcomes. It is well-established that family dysfunction is one reason that youth run away from home. However, less research focuses on how both families and schools influence youths’ likelihood of running away from home. Drawing from a sample of 4,546 youth from the 1997 National Longitudinal Survey of Youth, I examine how youths’ perceptions of their schools’ safety, experiences with bully victimization, and bonds with their families and their schools predict the likelihood of running away from home. I find that youths’ negative perceptions of their schools’ safety increase the likelihood that they will run away from home. Additionally, I discover that youth who have been the victims of bullying are more likely to run away from home compared to their peers who have not been bullied. My findings also suggest a cumulative effect between youths’ perceptions of unsafe schools and experiences with bullying, suggesting that youth are most likely to run away from home when they feel unsafe at school and have been the victim of childhood bullying. These findings are important because they have implications for policy development. My findings suggest that (a) promoting a positive and inclusive school environment and (b) helping youth foster stronger relationships may help deter youth from running away from home.

Authors: Riley Allison
Published: September 2019

Youth programs are an important context for social and emotional learning (SEL). To maximize opportunities for the development of skills such as self-management, empathy, and goal setting, youth workers need resources to increase practices that support SEL. Social and Emotional Learning in Practice: A Toolkit of Practical Strategies and Resources, Second Edition is a compilation of tools, templates, and activities that youth development programs can use to (a) enhance staff knowledge of SEL, how their program supports SEL, and their own emotional intelligence; (b) establish expectations, give feedback, and integrate reflection; (c) integrate SEL into program activities; and (d) collect SEL data for improvement. The 149-page toolkit is grounded in the Ways of Being model and is also informed by youth workers and youth from a variety of organizations. This is a turnkey resource that will be useful to youth development workers with a range of goals from overhauling their approach to SEL to identifying one activity for a single day of programming. The 2nd edition includes new icebreaker activities, an SEL Superpowers Board Game, creative data collection strategies, a reading list, and more.

A Script for the Witch: Witches' Voices in Two British Dramas
Authors: Handley Janet
Published: September 2019

This article examines two dramas that use historical representations of witchcraft and work from original sources as a starting point: The Witch of Edmonton by Rowley, Dekker, and Ford (1621) and Witchcraft by Joanna Baillie (1836). Whilst the majority of those convicted of witchcraft in the early modern period were women, finding a female voice in historical sources is difficult. What is striking about these plays therefore, is the prominent voice allocated to the witch figures on stage. This not only presents a challenge to the control of the official narratives but draws attention to the social mechanisms at work in the conviction of a witch. The main argument is that the plays address an absence in the source materials; by presenting what can be termed as “missing evidence” through the voice of the witch, the plays contribute to the debate on witchcraft and force the audience to judge anew.

Published: September 2019

The purpose of the study was to determine the effect of ASEAN-China Free Trade Area (ACFTA) on Indonesia's leading export commodities to China, Hong Kong and ASEAN countries. The methodology used is the model used below is based on New Trade Theory, which involves Comparative Advantage determinants including the total size of the country's economy, similarities in economic size, and differences in relative endowment factors. From the intended purpose, the results of this study are that commodities experiencing the largest growth in exports to all countries in 2010 were commodities with codes: 15, 87, 29 and 40. Meanwhile, commodities with code: 87: Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof, and 27: Mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes, were export commodities whose growth was relatively stable, while commodities with code 26: ores, slag and ash, actually declined, and the potential for Indonesian trade cooperation with ASEAN-4 is still wide open. This was marked by an increase in Indonesia's exports to ASEAN-4 in 2010.
Evaluation of the readiness of nurse anesthetists in Ghana for a master’s degree completion program: An exploratory, observational study
Authors: Kwetey Philip Kwame , Nyght Donna , Bennetts Paul
Published: September 2019

Ghana is a developing country in West Africa with limited anesthesia providers impacting surgical access and anesthesia safety. There are only two anesthesia providers per 100,000 population, with the majority of providers being nurse anesthetists, most of whom hold only diplomas, and more recently, bachelor’s in anesthesia education. This paper reports an observational study exploring the prospects of an advanced degree at the master’s degree level for practicing nurse anesthetists in Ghana. Three focus groups and one semi-structured individual interview were conducted with a total of 69 participants. Four major themes emerged following data analysis: desire for improved clinical expertise; focus on research methods to improve patient outcomes; perceived inadequate physician support for graduate nurse anesthetists (NA) education and infrastructure; and desires for an advanced degree for career progression. Findings highlight the readiness of nurse anesthetists in Ghana for an advanced degree and the necessary infrastructure and needed areas of clinical anesthesia education and research that must be included in the curriculum development for a master’s level education.
