Waste Collection in Low-density Areas and Air Pollutants
Formed in the Process
Authors: Vilms Monica , Voronova Viktoria
Published: August 2017

The particular problems waste collection in low-density areas include the long travel distances required together
with the small amount of waste that can be collected during a long journey. The current research investigates the amount of air
pollutants (CO2, CO, HC, NOx and PM) formed in low-density areas when the current waste collection system is applied, and
it proposes options for the minimisation of pollutant emissions. The calculation of air pollutants was carried out according to
the amount of burnt fuel. There are no requirements for waste truck emission levels in low-density areas. Emissions could be
reduced if there were requirements to use at least EURO III trucks or trucks that comply with higher standards. The optimisation
of discharge frequency needs to be dealt with. Emptying containers should be carried out at the same time and in the same
collecting area. If different waste types are collected according to the door-to-door system, trucks that can collect different
waste types simultaneously should be used. The quantity of emissions could be reduced by replacing the door-to-door system
by a waste collection point in a village or a waste station in a municipality centre.
Tensile Strength of Barrier Material
Authors: Zabielska-Adamska Katarzyna , Wasil Mariola
Published: August 2017

The most significant element of the municipal landfill construction is leak-proof assurance which reduces the
negative influence of waste on the environment. Mineral liners and covers are correctly built-in cohesive soil layers,
with a coefficient of permeability less than 10−9 m/s. Recently, researchers have conducted investigations with the possibility
of utilising fly ash as a mineral barrier material. A very important part in the selection of material for the barrier
is determining its ability to deformation. Its destruction is initiated by the process of the formation and propagation of
cracks caused by tensile stress. Tensile strength was determined for the compacted samples of fly ash and ash with the
addition of sodium bentonite which improves plasticity of the ash, as well as for compacted clay, for comparison. Laboratory
tests were performed using indirect method (Brazilian test) on disc-shaped samples, using a universal testing
machine with a frame load range of ± 1 kN. It was found that sodium bentonite significantly affects the tensile strength
of fly ash. The obtained values of deformation and tensile strength of compacted fly ash containing up to 5% bentonite
have been compared to those obtained for the clay used in mineral sealing.

Authors: Dauknys Regimantas , Mažeikienė Aušra
Published: August 2017

The article analyses Lithuanian rivers, 32 of which have been selected as non-complying with the require-ments of good condition. Furthermore, 15 discharge facilities that discharge wastewater to the aforementioned rivers from agglomerations with population equivalent (PE) greater than 2,000 have been selected. The assessment of the quality of treated wastewater according to the allowable impact on the reception facility has been carried out and has been compared with the currently regulated minimum allowable values of concentrations of pollutants. The analysis of the impact of quality of treated wastewater on the ecological status of rivers has been presented. It has been established that the pollution of rivers would be decreased by an average 8% (organic pollutants and total nitrogen) and by 22% (total phosphorus), if the allowable concentrations of pollutants according to the impact on the reception facility were ensured in the analysed treatment plants with PE greater than 10,000.

Published: August 2017

Due to the fact that resources of phosphorous are limited and are expected to get exhausted in the next 30 years the management of this resource has become extremely important. Most of the phosphorus compounds are lost forever, because they are discharged with sewage into surface water, causing eutrophication and in this way generating further issue and challenge. The aim of the study was to investigate the capacity to retain phosphorus compounds on sorption material. During the experiments, both synthetic and real wastewater were used. The synthetic wastewater simulated the composition of the reject water (RW) generated during the mechanical dewatering of the digested sewage sludge, and the real RW comes from WWTP in Gdansk. The investigation in steady conditions was carried out with Phoslock® which is chemically lanthanum clay. The results of the investigation are related to the determination of the sorption capacity with respect to the analyzed content of phosphorus compounds for stable conditions the determination of hydraulic load and way and time of mixing. For the synthetic wastewater the removal efficiency of phosphorous was 99.8% while for reject water (RW) generated during the mechanical dewatering of the digested sewage sludge was lower and equal to 85%.

Authors: Mamak Mustafa , Üneş Fatih , Kaya Yunus Ziya , Demirci Mustafa
Published: August 2017

Evapotranspiration (ET) estimation is a primary problem for irrigation engineers and hydraulic designers because it is an important part of hydrologic cycle. Even it is non-negligible in hydraulic design calculations, it is not clear enough to estimate or calculate ET. There are some meteorological parameters which effect ET directly or indirectly such as Relative Humidity (RH), Solar Radiation (SR), Air Temperature (AT) and Wind Speed (U). In this study authors used Adaptive Neuro-Fuzzy Inference System (ANFIS) for prediction of ET and results are compared with Penman FAO 56 empirical formula. 1158 daily AT, SR, RH and U values are used to train ANFIS model and 385 daily values are used to test it. ANFIS model determination coefficient with daily observed ET values found as 0.909. Also test set values are used to calculate Penman FAO 56 formula and the determination coefficient of Penman FAO 56 with daily observed ET values found as 0.857. For the comparison of the ANFIS model and Penman FAO 56 formula results Mean Square Error (MSE) and Mean Absolute Error (MAE) are computed. According to the comparison it is understood that ANFIS model has better performance than Penman FAO 56 empirical formula for the prediction of daily ET.
Reduction of Apparent Water Losses
Authors: Rimeika Mindaugas , Albrektienė Ramunė
Published: August 2017

The water loss levels are very different between European countries as water loss varies from 7% to 50%. According to data from the Lithuanian Water Supply Association, in 2015 about 124 mln. m³ of ground water was supplied to the network, but only 94 mln. m³ of it was sold, while the remaining share represented water losses – 30 mln. m³ per year. An average water loss level in Lithuania is 24%, varying from 52% to 17%. Local water utilities take a little care of apparent water losses. This article deals with an investigation of apparent losses in Alytus and other cities in Lithuania. The reduction of apparent water losses is quite a different field as it does not require large additional investments and can produce quick and efficient results. Article presents the results on the ways for reduction of apparent water losses in Lithuanian water supply systems. The aim of research is to show that apparent water losses consist of considerable share of water losses and to prove that inconsiderable efforts can significantly cut down water losses and improve the utilities’ financial situation. Article present findings of night water consumption, used for DMA allowed minimum water calculation. Analysing water consumption data in blockhouses the minimum night water volume was determined (0.9 l/h/flat).

Published: August 2017

In these latter days it has become topical to reconsider, the technologies and practice of regulated for drainage purposes streams supervision, to find ways how to combine agricultural productivity and restore lost ecological balance at least partially. The article analyzes the influence of natural and regulated stream stretches on water quality and stream self-purification effectiveness. The analysis of nitrate concentration in water samples taken from natural and regulated stream stretches was conducted for the identification of water quality. Nitrate (NO3) concentrations and their alternation during different seasons were studied. The conducted analysis revealed that stream nitrate self-purification is better in natural stream stretches. An average coefficient of self-purification recorded in the course of the research in natural stretches was 0.57, whereas in a regulated stretch – 0.09. On purpose to improve surface-water quality and self-purifi-cation effectiveness it is suggested to naturalize regulated stream stretches, to allow woody vegetation grow on slopes, to encourage meandering, pools and shoals forming processes in floodplains.
Evaluating the Performance of Low-Energy Feed Forward Osmosis System for Desalination using Impaired and Saline Water Sources
Authors: Tota-Maharaj Kiran
Published: August 2017

Forward Osmosis (FO) is a natural process of treating water or wastewater due to the difference in osmotic pres-sures. FO is a membrane separation technology, applicable to food processing, industrial wastewater treatment and seawater or brackish water desalination. The phenomena of FO processes occur whereby water molecules are driven across a semi-permeable membrane by an osmotic pressure gradient that is generated from a higher concentrate draw solution. FO processes can recover potable water resources from wastewater streams through the flow of pure water from a lower concentrated feed solution towards higher concentrated draw solutions leaving behind pollutants, impurities, and salts in the semi-permeable membrane. This paper assesses the design, build and testing of a laboratory scaled Feed Forward Osmosis (FFO) system for treating river water collected from the River Medway, Kent, England. The FO process was a highly effective form of river water treatment and able to treat the River Water with high rejection rates of solutes (>90%). Experimental results showed that the FFO system can achieve a better performance when the molarity of the draw solution is higher. The average solute rejection rate of the FO membrane for both inorganic and organic compounds was 94.83 %. Moreover, the operation of the forward osmosis membrane illustrated that it has a lower fouling propensity and higher solute rejection capabilities. The pilot scaled FFO system has the ability for greater salt rejection and lower electronic conductivity levels which resulted from the successful desalination of river water. A sodium chloride (NaCl) or saltwater draw solution performed positively in inducing higher os-motic pressures with a substantial effect of lower energy requirements for the system. Lower energy consumptions of the FFO system allow similar water treatment possibilities with energy savings potential. The FFO system showed to be an environ-mentally viable and economically feasible river water treatment technology.

The progenitor systems of the class of “Ca-rich transients” is a key open issue in time domain astrophysics. These intriguing objects exhibit unusually strong calcium line emissions months after explosion, fall within an intermediate luminosity range, are often found at large projected distances from their host galaxies, and may play a vital role in enriching galaxies and the intergalactic medium. Here we present multiwavelength observations of iPTF15eqv in NGC 3430, which exhibits a unique combination of properties that bridge those observed in Ca-rich transients and SNe Ib/c. iPTF15eqv has among the highest [Ca ii]/[O i] emission line ratios observed to date, yet is more luminous and decays more slowly than other Ca-rich transients. Optical and near-infrared photometry and spectroscopy reveal signatures consistent with the supernova explosion of a

star that was stripped of its H-rich envelope via binary interaction. Distinct chemical abundances and ejecta kinematics suggest that the core collapse occurred through electron-capture processes. Deep limits on possible radio emission made with the Jansky Very Large Array imply a clean environment (n ≲ 0.1 cm−3) within a radius of

cm. Chandra X-ray Observatory observations rule out alternative scenarios involving the tidal disruption of a white dwarf (WD) by a black hole, for masses >100 M
⊙. Our results challenge the notion that spectroscopically classified Ca-rich transients only originate from WD progenitor systems, complicate the view that they are all associated with large ejection velocities, and indicate that their chemical abundances may vary widely between events.
Influence of Intermittency on the Quasi-perpendicular Scaling in Three-dimensional Magnetohydrodynamic Turbulence

Published: August 2017

Solar wind fluctuations reveal the ubiquity of intermittency, which is believed to affect the spectral signatures of turbulence. In this work, based on simulation of driven compressible MHD turbulence, we apply the wavelet technique to the magnetic field and velocity to identify intermittency, and we analyze the influence of the intermittency on the quasi-perpendicular scaling in the inertial range. The numerical results show that the original magnetic and velocity fluctuations are anisotropic, and have a power anisotropy with a spectral index approaching the Iroshnikov–Kraichnan

scaling in the direction quasi-perpendicular to the local mean magnetic field. As in observations of the solar wind fluctuations, as the scale decreases in the simulation, the calculated probability distribution functions (pdfs) of the wavelet coefficients become extended on both tails of the non-Gaussian distribution, with a rapid increase in flatness. After intermittency has been removed from the driven turbulence, at each scale, the pdfs approach a Gaussian distribution, with the flatness being ∼3. Meanwhile, the quasi-perpendicular scaling for both fluctuations becomes steeper and close to a Kolmogorov

scaling, which may be a result of the stronger intermittency in the quasi-perpendicular direction and at the smaller scales. These results suggest that there is intermittency superposed on the “background” turbulence that seems to have the Kolmogorov scaling, whereby the overall slope is getting flatter with the involvement of intermittency.
Is There a Temperature Limit in Planet Formation at 1000 K?
Authors: Demirci Tunahan , Teiser Jens , Steinpilz Tobias , Landers Joachim , Salamon Soma , Wende Heiko , Wurm Gerhard
Published: August 2017

Dust drifting inward in protoplanetary disks is subject to increasing temperatures. In laboratory experiments, we tempered basaltic dust between 873 K and 1273 K and find that the dust grains change in size and composition. These modifications influence the outcome of self-consistent low speed aggregation experiments showing a transition temperature of 1000 K. Dust tempered at lower temperatures grows to a maximum aggregate size of 2.02 ± 0.06 mm, which is 1.49 ± 0.08 times the value for dust tempered at higher temperatures. A similar size ratio of 1.75 ± 0.16 results for a different set of collision velocities. This transition temperature is in agreement with orbit temperatures deduced for observed extrasolar planets. Most terrestrial planets are observed at positions equivalent to less than 1000 K. Dust aggregation on the millimeter-scale at elevated temperatures might therefore be a key factor for terrestrial planet formation.
13C Isotopic Fractionation of HC3N in Two Starless Cores: L1521B and L134N (L183)
Authors: Taniguchi Kotomi , Ozeki Hiroyuki , Saito Masao
Published: August 2017

We observed the

rotational lines of the normal species and three 13C isotopologues of HC3N at the 45 GHz band toward two low-mass starless cores, L1521B and L134N (L183), using the Nobeyama 45 m radio telescope in order to study the main formation pathways of HC3N in each core. The abundance ratios of the three 13C isotopologues in L1521B are derived to be [H13CCCN]:[HC13CCN]:[HCC13CN] = 0.98 (±0.14):1.00:1.52 (±0.16) (

). The fractionation pattern is consistent with that at the cyanopolyyne peak in Taurus Molecular Cloud-1. This fractionation pattern suggests that the main formation pathway of HC3N is the neutral–neutral reaction between C2H2 and CN. On the other hand, their abundance ratios in L134N are found to be [H13CCCN]:[HC13CCN]:[HCC13CN] = 1.5 (±0.2):1.0:2.1 (±0.4) (

), which are different from those in L1521B. From this fractionation pattern, we propose that the reaction between HNC and CCH is a possible main formation pathway of HC3N in L134N. We find out that the main formation pathways of the same molecule are not common even in similar physical conditions. We discuss the possible factors that could make a difference in the fractionation pattern between L134N and L1521B/TMC-1.

We present a demonstration of delensing the observed cosmic microwave background (CMB) B-mode polarization anisotropy. This process of reducing the gravitational-lensing-generated B-mode component will become increasingly important for improving searches for the B modes produced by primordial gravitational waves. In this work, we delens B-mode maps constructed from multi-frequency SPTpol observations of a 90 deg2 patch of sky by subtracting a B-mode template constructed from two inputs: SPTpol E-mode maps and a lensing potential map estimated from the Herschel 500 μm map of the cosmic infrared background. We find that our delensing procedure reduces the measured B-mode power spectrum by

% in the multipole range

this is shown to be consistent with expectations from simulations and to be robust against systematics. The null hypothesis of no delensing is rejected at

. Furthermore, we build and use a suite of realistic simulations to study the general properties of the delensing process and find that the delensing efficiency achieved in this work is limited primarily by the noise in the lensing potential map. We demonstrate the importance of including realistic experimental non-idealities in the delensing forecasts used to inform instrument and survey-strategy planning of upcoming lower-noise experiments, such as CMB-S4.
A Search for FRB 121102-like Persistent Radio-luminous Sources—Candidates and Implications for the FRB Rate and Searches
Authors: Ofek Eran O.
Published: August 2017

The localization of the repeating fast radio burst (FRB), FRB 121102, suggests that it is associated with a persistent radio-luminous compact source in the FRB host galaxy. Using the FIRST radio catalog, I present a search for luminous persistent sources in nearby galaxies, with radio luminosities

of the FRB 121102 persistent source luminosity. The galaxy sample contains about 30% of the total galaxy g-band luminosity within

Mpc, in a footprint of 10,600 deg2. After rejecting sources likely due to active galactic nuclei activity or background sources, I am left with 11 candidates that are presumably associated with galactic disks or star-formation regions. At least some of these candidates are likely to be due to chance alignment. In addition, I find 85 sources within

of galactic nuclei. Assuming that the radio persistent sources are not related to galactic nuclei and that they follow the galaxy g-band light, the 11 sources imply a 95% confidence upper limit on the space density of luminous persistent sources of

Mpc−3, and that at any given time only a small fraction of galaxies host a radio-luminous persistent source (

). Assuming a persistent source lifetime of 100 years, this implies a birth rate of

yr−1 Mpc−3. Given the FRB volumetric rate, and assuming that all FRBs repeat and are associated with persistent radio sources, this sets a lower limit on the rate of FRB events per persistent source of

yr−1. I argue that these 11 candidates are good targets for FRB searches and I estimate the FRB event rate from these candidates.
Advocating the Woman Affirmative Action and Women Empowerment in Rural Cross River State of Nigeria
Authors: Calvain Endong Floribert Patrick
Published: August 2017

Most media initiatives (particularly radio and television programs) bordering on women empowerment and the woman affirmative action tend to give less attention to the rural woman to the advantage of her urban counterpart who, to a high extent is already abreast of the feminist concept. This more or less “accidental” discrimination is causing the grassroots women to stay somewhat in ignorance and to further be victimized by the viscous patriarchal system which prevails in traditional circles. Based on a documentary analysis and semi structured interviews with experts, this chapter explores the role of the local media and the civil society in the sensitization of the rural woman towards emancipation and socio-economic empowerment in Cross River State of Nigeria. The chapter equally assesses the effectiveness of the advocacy strategies employed by local media houses and NGOs for such purposes. It assesses civil society's use of the media for the women affirmative action in rural Cross River State of Nigeria as well as the local media potential to push this affirmative action in the grassroots.
How to Use Parody and Humour to Teach Digital Literacy
Authors: Pereira Luis
Published: August 2017

Based on the assumption digital literacy needs a practical approach and actions, this chapter presents an initiative that intends to develop digital skills in a very creative way. Considering the challenge educators (for instance, teachers or librarians) face to promote digital literacy skills especially to young people in a very engaging way, some training was developed to create a possible answer to that problem. This chapter discusses the impact of that initiative that highlights the potential of humour and parody that we can find on digital media to teach digital literacy. According to some attendants, this approach was creative, engaging and built in their minds alternative paths to explore digital literacy and critical thinking.
Integrating Digital Literacies Into an Undergraduate Course
Authors: Kapepo Meke I. , Mayisela Tabisa
Published: August 2017

The purpose of this chapter is to share a successful case of how ICT was used for educational inclusiveness by students from previously disadvantaged backgrounds. This chapter further illuminates how students could be supported in acquiring digital and academic literacy skills, within a discipline context. Lecturers often find it difficult to define digital literacy beyond the use of ICT in a classroom, or understand how students' acquisition of digital literacy skills could be supported or further expanded into students' academic literacy skills. This piece of work therefore, provides insight to academics, researchers and students, on how: (1) ICT could be integrated into the curriculum; (2) digital literacy could be embedded into the curriculum; and (3) students could be supported in acquiring graduate attributes and skills that make them fit for the workplace.
Facilitating Multimodal Literacy Instruction Through Digital Curation
Authors: Mills Michael S.
Published: August 2017

It is becoming clearer that multimodal literacies (specifically textual, visual, and digital) will frame classroom instruction for the near future. The mission of this chapter is to highlight the potential of digital curation as a means for facilitating multimodal literacy instruction and the subsequent creation of dynamic digital learning resources by both students and teachers. Over the past several decades, there has been a tremendous shift in how educators and students communicate, learn, and share ideas. As society moves more toward creating and sharing information through the aggregation, filtering, and customization of digital content, it is imperative that educators create opportunities for students to do likewise. Drawing on recent research on the cognitive benefits of multimodal literacy instruction and its potential for increasing opportunities for student engagement, this chapter will provide a rationale for, and subsequently sketch, a practical approach for teaching collaborative digital curation using Web 2.0 resources.
Conceptualising mLearning Literacy
Authors: Ng Wan
Published: August 2017

Research into the educational application of mobile technologies has increased dramatically in recent years. Much has been written about mobile learning and its various pedagogical practices and issues as well as the theoretical frameworks that have been developed to underpin the studies in the reports. However, little has been written about the literacy associated with learning with mobile devices and whether there is a place for its development in education. This conceptual paper seeks to explore mLearning literacy, the digital literacy associated with learning with mobile devices, and asks the question: What is mLearning literacy and what are its implications for educators? In the paper, the author will argue that fundamental to learning with mobile devices is the need to develop the associated digital literacy in students. The author proposes that being mLearning literate would empower students to learn more independently and more safely when using mobile devices and their applications.

Emerging technologies enhance student learning through the explicit intentional educational design such as Active Learning Classrooms, Flipped Classrooms, Problem Based Learning, and Project Based Learning to empower students. Throughout this article, we will describe several emerging technologies that support learning for the 21st century using student-centered learning models. By means of vignettes, we model how a Metacognitive Technological Pedagogical Content Knowledge Framework (M-TPACK) supports the use of emerging technologies for active learning (Wilson, Zygouris-Coe, Cardullo, & Fong, 2013). Throughout all of the vignettes, we draw connections to the various emerging technologies and the level of integration using both Blooms Taxonomy (Bloom et al., 1956) and the SAMR Model: Substitution, Augmentation, Modification, and Redefinition (Puentedura, 2006).
Impediments to Digital Fabrication in Education
Authors: Smith Rachel Charlotte , Iversen Ole Sejer , Veerasawmy Rune
Published: August 2017

Digital fabrication technologies are increasingly integrated across subjects in primary and secondary education. Focus on the potentials of these technologies has mainly been on the support to STEM oriented learning goals, while emphasis on teachers' roles with the new learning processes of technology and design is largely absent. The paper addresses the experiences and challenges that digital fabrication technology present for teachers in educational environments, and the impediments that are linked to the teachers' roles in design processes of digital fabrication. Based on a research study with eight primary and lower secondary teachers, the findings point to four central impediments for integrating digital fabrication and design into school environments. The findings extend current perceptions of digital technology in education towards exploratory processes of investigation in which the teachers' roles are fundamental.

Published: August 2017

Several government programs oriented to contribute in reducing digital divide gaps have emerge in Mexico, particularly in States like Jalisco, Nayarit, Nuevo Leon, Veracruz, and Aguascalientes. However, current alternatives have certain weaknesses and issues that should be solved in order to provide appropriate literacy. To contribute in achievement of this goal, here is proposed an alternative to conform a strategy based on Massive Open Online Courses (MOOCs). First, a study was performed to establish the actual level of digital competences of current program users, and then obtained feedback was considered to structure the contents to offer through the MOOCs. This study was performed in the Aguascalientes state government program Vagones de Ciencia.

Published: August 2017

This chapter examines the use of disciplinary literacy in elementary and middle grade science classrooms that participated in a one-to-one iPad initiative. Results of teacher instruction in science disciplinary literacy practices in a one-to-one iPad technology integration, examples of collaborations, and observational data are shared. The teachers in this study demonstrated an overreliance on basic and intermediate literacy practices, with a few using emergent disciplinary practices in their science instruction. We look to extend the STEM and technology integration conversation to include disciplinary literacy practices. We conclude with a call for stronger science disciplinary literacy instruction in teacher education programs, as well as greater collaboration among literacy teachers, science teachers, and researchers. We also recommend developing coaching programs that work with teachers to increase the rigor of their science content, implement intermediate and disciplinary literacy practices, and utilize technology in a transformational manner.

Technology Aspects of Information Literacy in the Workplace
Authors: Farmer Lesley S. J.
Published: August 2017

Workplaces need information literate employees in order to manage the increasing quantity and complexity of information that impacts their organizations, yet they provide uneven information literacy education. Information and technology literacy are also imperative for the organization as a whole. Decision makers should systematically identify key information and technology literacy processes within the organization, and assess the learning gaps of their employees. Employers should allocate human and material resources to facilitate a variety of formal and informal learning venues, incorporating technology. Such education should also reflect andragogical principles and authentic collaborative learning activities, which can be facilitated by technology-based collaborative tools.
The Relationship Between Online Information Seeking Anxiety and English Reading Proficiency Across Gender
Authors: Rahimi Mehrak , Bayat Zahra
Published: August 2017

In this chapter the relationship between Iranian EFL learners' online information seeking anxiety and reading ability is investigated. The sample included 177 high-school students of an urban area in Iran. In order to measure their reading ability, the reading section of Primary English Test (PET) was used. To assess their online information searching anxiety, Information Seeking Anxiety scale (ISAS) was used. The results of the correlational analysis showed that there is a negative relationship between ISAS (and all its components) and PET. When male and female participants were considered separately, English reading was not found to be related to anxiety among boys; while it was moderately associated with anxiety among girls. The result of regression showed that EFL reading ability is a significant predictor of online information seeking anxiety and can predict more than 7% of the variance of online information searching anxiety; however the power of reading to reduce searching anxiety was found to be much stronger (more than 18%) among females.
Inquiry-Based Science Education and the Digital Research Triad
Authors: Tsybulsky Dina , Levin Ilya
Published: August 2017

The chapter deals with a new research field that has arisen at the intersection of scientific experiment and emerging digital technologies. The classical triad of experimental research ‘subject-instrument-object' and its implementation in science education are in the focus of the chapter. The triad is studied in its evolution to a so-called digital triad corresponding to the experimental science of digital society. In the digital triad, each of the three components are transformed. The knowing subject - researcher is transformed to the digital scholar; the experimental instrument is transformed on the base of emerging cloud and mobile technologies; the research object comprising hybrid natural-artificial components emerges. The digital transformations of the experimental research triad and educational practices based on the digital triad are manifested in a number of pioneer inquiry-based projects analyzed in the chapter.
Digital Literacy Instruction in Afghanistan
Authors: Edwards Mike
Published: August 2017

This chapter uses the American military's purchase of a $5.6 million contract to supply the National Military Academy of Afghanistan with laptop computers as the occasion to investigate the complex and overdetermined intersections of digital, administrative, and literacy technologies. These intersections and the challenges they produced for the author as a Western mentor working with Afghan postsecondary instructors in ESL and digital literacies reveal the problematic homogenizing Western economic and cultural assumptions and the intense naturalization of administrative technologies that accompany the denaturalized use of digital and textual technologies in global contexts. The connections of those challenges to recent scholarship in rhetoric and composition highlight the limitations of that scholarship's conception of political economy in a global digital context and also offers new possibilities for imagining hybrid multilingual digital literacies on a global scale.

Technology has brought about considerable changes in our private, social and professional lives, as well as in our culture and values. Therefore, educational frameworks should make an effort to become more relevant for young students and prepare them for the future in all aspects of career and life, with a focus on Science, Technology, Engineering and Math (STEM). This chapter will discuss the opportunities and challenges of integrating technology into preschool classrooms (3-6 years of age). It attempts to determine the essence of judicious, proportionate, and beneficial integration of technology in preschool, with a particular focus on science and inquiry. Consideration is given to maintaining the children's creativity, their joy of play, their concrete and sensory exploration, their unmediated observation of their environment, their social interactions, and their safety. Examples of actual practices from preschool classrooms are presented followed by recommendations for successful technology integration in preschool curriculum.

In this chapter we look at how BYOD in educational “classroom” environments is touching each individual where they communicate, get their information, and connect socially and globally. We aim to provide perspectives which include the learner, faculty, and staff in higher education. Additionally, teaching methods, use and needs of faculty and staff are considered, as well as privacy, security and policy. This is an investigative look at the trends and possibilities of BYOD and its future, and a consideration of the impact on faculty, students, and staff in university settings.
A Triangulation Approach to Understand Multi-Cultural College Students' Technology Literacy in a Composition Classroom
Authors: Kang Yowei
Published: August 2017

Despite intense debates over the use of computer and networked technologies in composition classrooms, research has been limited by one dimensional support or criticism of integrating technologies into classrooms. The inability to consider students as a central role in the literacy acquisition process has led to many problems in the rhetoric of technology as well as in the implementation of computer and networked technologies in a composition classroom. This study employed a triangulation method to gather empirical data to better assess and critique the rhetoric of technology in composition pedagogy literature. The author collected both quantitative and qualitative data to uncover issues critical to students' technology literacy in a technologized composition classroom. A questionnaire survey was distributed to 62 bi-cultural undergraduate students conveniently recruited from a large southwestern university near the U.S.-Mexico border. Findings from the quantitative method discovered that English instructors' technology literacy had significant impacts on students' own technology literacy. Furthermore, narratives from the qualitative method identify the following themes about technology: effectiveness, practicality, instrumentality, and institutional enforcement. In conclusion, the author discusses the importance of technology literacy in composition classrooms to demonstrate its implications on global literacy theory and practices.
Orientation-Based Interaction on Mobile Devices and Desktops - An Evaluation

Nowadays, mobile devices, such as smartphones, tablets or smartwatches, are essential items in our daily life. Further, more and more people use smart mobile devices in their everyday work for remote controlling, observing diagrams, performing web analytics, etc. However, the full potential of mobile devices is not tapped yet; built-in sensors such as accelerometers or gyroscopes offer a wide range of interaction capabilities, which are still often not fully used in nowadays mobile applications. On the other hand, desktops are still the dominating working device, but with significantly differing interaction means. With additional hand tracking devices capturing the user's gestures additional input possibilities are available but still often unused. In this paper, we investigate on a concept for orientation-based touch-less interaction. Depending on the type of device - traditional desktop or a mobile device - we use an interaction metaphor called "Waggle"; utilizing of tilting and turning of either the user's hand or the mobile device itself for additional input possibilities. Based on the results of two pilot studies for both environments, basic parameters for future design decisions are derived: on the one hand, the maximum angle for basic rotation axes are evaluated. On the other hand, different discretizations of tilt and turn angles are investigated. Based on the outcome of both studies the optimal configuration for the use of the Waggle interaction metaphor in future applications on both mobile and desktop environments are defined.
A Method to Predict and Visualize the Wheel and Work Surface Topography in Surface Grinding

Published: August 2017

Visualization of work surface topography through simulations is very challenging task in grinding process due to the complexity of wheel-work interactions with a very high number of cutting points (grits). Kinematic mapping of abrasive grits on a three-dimensional wheel topography enables the evaluation of ground surface topography through simulations. In this paper, a method for generating the ground surface topography based on wheel specifications is presented. Abrasive grits size, abrasives volume percentage and their nature of distribution on the wheel surface are considered in the modeling and visualization of wheel topography. The simulation results of ground surface topographies prove the feasibility of the developed method.

We present a methodology to analyze and visualize an ensemble of finite pointset method (FPM) simulations that model the viscous fingering process of salt solutions inside water. In course of the simulations the solutions form structures with increased salt concentration value, called viscous fingers. These structures are of primary interest to domain scientists since it is not deterministic when and where viscous fingers appear and how they evolve. To explore the aleatoric uncertainty embedded in the simulations we analyze an ensemble of simulation runs which differ due to stochastic effects. To detect and track the viscous fingers we derive a voxel volume for each simulation where fingers are identified as subvolumes that satisfy geometrical and topological constraints. Properties and the evolution of fingers are illustrated through tracking graphs that visualize when fingers form, dissolve, merge, and split. We provide multiple linked views to compare, browse, and analyze the ensemble in real-time.
Bioclimatic approach to assessing the potential impact of climate change on two flea beetle (Coleoptera: Chrysomelidae) species in Canada

Both the striped flea beetle,Phyllotreta striolata(Fabricius), and crucifer flea beetle,Phyllotreta cruciferae(Goeze) (Coleoptera: Chrysomelidae), are invasive alien species to North America. In western Canada, they are the most significant insect pests of cruciferous (Brassicaceae) crops. Climate is the one of the most dominant factors regulating the geographic distribution and population density of most insect species. Recent bioclimatic simulation models of the two flea beetle species fostered a better understanding of how the two species responded to selected climate variables. They demonstrated that selected climate variables increased population densities and geographic range of the two species. General circulation model inputs were applied in this study to assess the impact of a changing climate on the response ofP. cruciferae and P. striolatapopulations. Model output, using the climate change scenarios, predicted that bothP. cruciferaeandP. striolatapopulations will shift north in future climates and the degree of geographic overlap between these two species will be greater than for current climate. This suggests that the two species could potentially cause economic losses over an expanded area in the future.

Enterprise architecture (EA) is a tool that aligns organization’s business-process with application and information technology (IT) through EAmodels. This EA model allows the organization to cut off unnecessary IT expenses and determines the future and current IT requirements and boosts organizational performance. Enterprise architecture may be employed in every firm where the firm or organization requires configurations between information technology and business functions. This research investigates the role of enterprise architecture in healthcare organizations and suggests the suitable EA framework for knowledge-based medical diagnostic system for EA modeling by comparing the two most widely used EA frameworks. The results of the comparison identified that the proposed EA has a better framework for knowledge-based medical diagnostic system.

Esta pesquisa procurou identificar os fatores que impactam a adoção e implementação do SPED segundo avaliação de gestores de empresas brasileiras, contemplando fatores estabelecidos pelo Modelo TOE, passando pelas dimensões tecnológica, organizacional e ambiental do referido modelo. Através do tratamento estatístico dos dados oriundos da aplicação de uma survey, buscou-se resposta aos objetivos de pesquisa. Detectou-se que, embora existam outros fatores influenciando decisões sobre adoção e implementação do SPED, a obrigatoriedade governamental, enquanto componente do contexto ambiental, demonstrou ser o principal vetor de impacto, isto é, de influência, sobre tais decisões. Isto pareceu decorrer do fato de que o governo ser um dos principais, se não o principal ator do ambiente regulatório.
