Deficitul de vitamină D reprezintă o problemă globală de sănătate publică, la toate grupele de vârstă, provocată în principal de expunerea insuficientă la lumina soarelui, diete necorespunzătoare, absorbție şi utilizare ineficiente, cerințe crescute sau pierderi mai mari. Cunoscând implicațiile vitaminei D în organism şi perioadele sensibile de creştere şi dezvoltare, este important să se efectueze determinări biologice, pentru o profilaxie adecvată şi pentru a interveni prompt când apar modificări. Grupele de vârstă la care se recomandă administrarea vitaminei D sunt sugarii (indiferent dacă sunt alimentați natural, cu formulă sau alimentație complementară) şi adolescenţii. În afară de rolul binecunoscut al vitaminei D în metabolismul fosfo-calcic, se discută din ce în ce mai mult de implicarea vitaminei D în patogenia bolilor non-musculo-scheletice.

Published: May 2020

In today’s competitive environment, the marketing is an imperative tool for the survival and sustainable growth
of any business or product. The objective of the undertaken research is to investigate the guerrilla marketing techniques for small and
medium enterprises (SMEs), and their impact on consumers’ purchase decision. Researchers have also the aim to examine the impact of brand
awareness and technology as mediating and moderating variables respectively in the guerrilla marketing process. A survey is undertaken
by potential consumers through structured questionnaire via a quantitative method of inquiry. The data is analyzed mainly through;
SEM-based structural modelling such as exploratory and confirmatory factors analysis, and conditional process analysis. The results
unveil that guerrilla marketing techniques consisting of viral marketing, strange occurrences, street graphics, and memorable events
have a positive and significant influence on the purchase decision. Findings of the undertaken research further demonstrated that brand
awareness is a potent mediating variable that significantly enhances the influence of purchase decision, and technology played a vital
role as a moderator that has a cogent impact between guerrilla marketing techniques and purchase decision of consumers. Thus, the empirical
testing confirmed the importance of modified model of guerrilla marketing, which will be benefitted to both marketing practitioners
and future researchers.
A Cross-correlation Study of High-energy Neutrinos and Tracers of Large-scale Structure
Authors: Fang Ke , Banerjee Arka , Charles Eric , Omori Yuuki
Published: May 2020

The origin of the bulk of the astrophysical neutrinos detected by the IceCube Observatory remains a mystery. Previous source-finding analyses compared the directions of IceCube events and individual sources in astrophysical catalogs. The source association method is technically challenging when the number of source candidates is much larger than the number of the observed astrophysical neutrinos. We show that in this large source number regime, a two-point cross-correlation analysis of neutrino data and source catalog can instead be used to constrain potential source populations for the high-energy astrophysical neutrinos, and provide spatial evidence for the existence of astrophysical neutrinos. We present an analysis of the cross-correlation of the IceCube 2010–2012 point-source data and a WISE–2MASS galaxy sample. While we find no significant detection of cross-correlation with the publicly available neutrino data set, we show that, when applied to the full IceCube data, which has a longer observation time and higher astrophysical neutrino purity, our method has sufficient statistical power to detect a cross-correlation signal if the neutrino sources trace the large-scale structure of the universe.

The luminous Type IIn SN 2010jl shows strong signs of interaction between the SN ejecta and dense circumstellar material. Dust may be present in the unshocked ejecta; the cool, dense shell (CDS) between the shocks in the interaction region; or in the circumstellar medium (CSM). We present and model new optical and infrared photometry and spectroscopy of SN 2010jl from 82 to 1367 days since explosion. We evaluate the photometric and spectroscopic evolution using the radiative transfer codes mocassin and damocles, respectively. We propose an interaction scenario and investigate the resulting dust formation scenarios and dust masses. We find that SN 2010jl has been continuously forming dust based on the evolution of its infrared emission and optical spectra. There is evidence for preexisting dust in the CSM as well as new dust formation in the CDS and/or ejecta. We estimate that 0.005–0.01 M
⊙ of predominantly carbon dust grains has formed in SN 2010jl by ∼1400 days post-outburst.

Recent integral field spectroscopy observations have found that about 11% of galaxies show star–gas misalignment. The misalignment possibly results from external effects such as gas accretion, interaction with other objects, and other environmental effects, hence providing clues to these effects. We explore the properties of misaligned galaxies using Horizon-AGN, a large-volume cosmological simulation, and compare the results with those of the Sydney-AAO Multi-object integral field spectrograph (SAMI) Galaxy Survey. Horizon-AGN can match the overall misalignment fraction and reproduces the distribution of misalignment angles found by observations surprisingly closely. The misalignment fraction is found to be highly correlated with galaxy morphology both in observations and in the simulation: early-type galaxies are substantially more frequently misaligned than late-type galaxies. The gas fraction is another important factor associated with misalignment in the sense that misalignment increases with decreasing gas fraction. However, there is a significant discrepancy between the SAMI and Horizon-AGN data in the misalignment fraction for the galaxies in dense (cluster) environments. We discuss possible origins of misalignment and disagreement.
Emission Signatures from Subparsec Binary Supermassive Black Holes. III. Comparison of Models with Observations

Published: May 2020

We present a method for comparing the Hβ emission-line profiles of observed supermassive black hole (SBHB) candidates and models of subparsec SBHBs in circumbinary disks. Using the approach based on principal component analysis, we infer the values of the binary parameters for the spectroscopic SBHB candidates and evaluate the parameter degeneracies, representative of the uncertainties intrinsic to such measurements. We find that as a population, the SBHB candidates favor the average value of the semimajor axis corresponding to log(a/M) ≈ 4.20 ± 0.42 and comparable mass ratios, q > 0.5. If the SBHB candidates considered are true binaries, this result would suggest that there is a physical process that allows initially unequal-mass systems to evolve toward comparable mass ratios (e.g., accretion that occurs preferentially onto the smaller of the black holes) or point to some, yet unspecified, selection bias. Our method also indicates that the SBHB candidates equally favor configurations in which the mini-disks are coplanar or misaligned with the binary orbital plane. If confirmed for true SBHBs, this finding would indicate the presence of a physical mechanism that maintains misalignment of the mini-disks down to subparsec binary separations (e.g., precession driven by gravitational torques). The probability distributions of the SBHB parameters inferred for the observed SBHB candidates and our control group of AGNs are statistically indistinguishable, implying that this method can in principle be used to interpret the observed emission-line profiles once a sample of confirmed SBHBs is available but cannot be used as a conclusive test of binarity.
Star Formation Occurs in Dense Gas, but What Does “Dense” Mean?
Authors: Evans Neal J. , Kim Kee-Tae , Wu Jingwen , Chao Zhang , Heyer Mark , Liu Tie , Nguyen-Lu’o’ng Quang , Kauffmann Jens
Published: May 2020

We report results of a project to map HCN and

 emission toward a sample of molecular clouds in the inner Galaxy, all containing dense clumps that are actively engaged in star formation. We compare these two molecular line tracers with millimeter continuum emission and extinction, as inferred from 13CO, as tracers of dense gas in molecular clouds. The fraction of the line luminosity from each tracer that comes from the dense gas, as measured by

mag, varies substantially from cloud to cloud. In all cases, a substantial fraction (in most cases, the majority) of the total luminosity arises in gas below the

mag threshold and outside the region of strong millimeter continuum emission. Measurements of

toward other galaxies will likely be dominated by such gas at lower surface densities. Substantial, even dominant, contributions to the total line luminosity can arise in gas with densities typical of the cloud as a whole (n ∼ 100 cm−3). Defining the dense clump from the HCN or

emission itself, similarly to previous studies, leads to a wide range of clump properties, with some being considerably larger and less dense than in previous studies. HCN and

have a similar ability to trace dense gas for the clouds in this sample. For the two clouds with low virial parameters, 13CO is definitely a worse tracer of the dense gas, but for the other four, it is equally good (or bad) at tracing dense gas.
Energetic Neutral Atom Flux from the Inner Heliosheath and Its Connection to Termination Shock Properties
Authors: Shrestha Bishwas L. , Zirnstein Eric J. , Heerikhuisen Jacob
Published: May 2020

We present statistical comparisons between energetic neutral atom (ENA) fluxes obtained using a global simulation of the heliosphere and data collected by the Interstellar Boundary Explorer (IBEX) spacecraft. The simulation of the inner heliosheath (IHS) ENA flux is based on a 3D steady-state heliosphere, while the data are from the IBEX-Hi instrument over the time period 2009–2015. The statistical comparison is performed by calculating the chi-square value between the simulated ENA fluxes and the data for each line of sight in the sky. A comparison with exposure-averaged data for solar minimum and solar maximum conditions is also performed to see the effect of solar wind (SW) properties on the IHS ENA fluxes. The model matches well with the data in the flanks and parts of the nose of the heliosphere, whereas the match is poor in the downwind tail, ribbon, and polar regions. We interpret these results to mean that (i) heliosheath plasma in the polar region consists of advected fast (or slow) SW during the solar minimum (or maximum) condition, and (ii) heliospheric termination shock parameters are likely different over the poles. A poor match at around 30° north and south of the downwind direction is likely due to the existence of a mixture of plasma that comes from fast and slow SW. While our results are consistent with a single heliotail, the shape of the heliosphere continues to be an area of active research, and more data and further modeling are needed to determine its true structure.

Accurate atmospheric parameters and chemical composition of stars play a vital role in characterizing physical parameters of exoplanetary systems and understanding of their formation. A full asteroseismic characterization of a star is also possible if its main atmospheric parameters are known. The NASA Transiting Exoplanet Survey Satellite (TESS) space telescope will play a very important role in searching of exoplanets around bright stars and stellar asteroseismic variability research. We have observed all 302 bright (V < 8 mag) and cooler than F5 spectral class stars in the northern TESS continuous viewing zone with a 1.65 m telescope at the Molėtai Astronomical Observatory of Vilnius University and the high-resolution Vilnius University Echelle Spectrograph. We uniformly determined the main atmospheric parameters, ages, orbital parameters, velocity components, and precise abundances of 24 chemical species (C(C2), N(CN), [O i], Na i, Mg i, Al i, Si i, Si ii, Ca i, Ca ii, Sc i, Sc ii, Ti i, Ti ii, V i, Cr i, Cr ii, Mn i, Fe i, Fe ii, Co i, Ni i, Cu i, and Zn i) for 277 slowly rotating single stars in the field. About 83% of the sample stars exhibit the Mg/Si ratios greater than 1.0 and may potentially harbor rocky planets in their systems.

Published: May 2020

The current descriptive cross-sectional study was conducted to determine the correlation between perceived social support and hopelessness of 609 Syrian refugees age ≥16 residing in Gaziantep City, Turkey. A sociodemographic questionnaire, the Multidimensional Scale of Perceived Social Support, and Beck Hopelessness Scale were used for data collection. Descriptive statistics, analysis of variance, and regression and correlation analyses were used to analyze the data. Syrian refugees had high levels of hopelessness, particularly motivation loss, and moderate levels of perceived social support. As perceived social support increased, hopelessness, feelings, expectations about the future, and motivation loss decreased. In accordance with these results, hopes of Syrian refugees for the future can be increased by improving their social support system. [

A hybridized weak Galerkin finite element scheme for general second-order elliptic problems
Authors: Li Guanrong , Chen Yanping , Huang Yunqing
Published: May 2020

In this paper, a hybridized weak Galerkin (HWG) finite element scheme is presented for solving the general second-order elliptic problems. The HWG finite element scheme is based on the use of a Lagrange multiplier defined on the element boundaries. The Lagrange multiplier provides a numerical approximation for certain derivatives of the exact solution. It is worth pointing out that a skew symmetric form has been used for handling the convection term to get the stability in the HWG formulation. Optimal order error estimates are derived for the corresponding HWG finite element approximations. A Schur complement formulation of the HWG method is introduced for implementation purpose.
Data Controller, Processor, or Joint Controller
Authors: Ivanova Yordanka
Published: May 2020

This chapter aims to examine critically the existing legal provisions on the concepts of controller, processor, and joint controller, as interpreted by the relevant non-binding guidelines and case law, and to propose a new “value chain” method for allocating responsibilities among joint controllers that is more effective and appropriate for the technology- and data-driven world. It also examines the corresponding data protection responsibilities of different data processing actors, in particular through the prism of the new accountability principle, which arguably includes not only obligations for means but also result-oriented obligations for compliance in terms of data subjects' effective and complete protection.
Is “Privacy” a Means to Protect the Competition or Advance Objectives of Innovation and Consumer Welfare?
Authors: Gorecka Arletta
Published: May 2020

The relationship between competition law and privacy is still seen as problematic with academics and professionals trying to adequately assess the impact of privacy on the competition law sphere. The chapter looks at the legal development of the EU merger proceedings to conclude that EU competition law is based on the prevailing approach and assesses decisions involving data through the spectrum of keeping a competitive equilibrium in hypothetical markets. Secondly, it considers the legal developments in the EU Member States' practice, which acknowledges the apparent intersection between the phenomena of competition law and privacy. This chapter attempts to propose that privacy concerns appear to hold a multidimensional approach on competition legal regime; nevertheless, it does not result in the need of legal changes within the remits of competition law, as the privacy concerns are already protected by the data protection and consumer protection law.
Erosion by Standardisation
Authors: Christofi Athena , Dewitte Pierre , Ducuing Charlotte , Valcke Peggy
Published: May 2020

This chapter examines the interplay between the GDPR and parallel private regulation in the form of privacy-related standards adopted by the International Organisation for Standardisation (ISO). Focusing on the understanding of ‘risks' in the GDPR and ISO respective ecosystems, it compares the GDPR requirement for Data Protection Impact Assessments (DPIAs) with ISO/IEC 29134:2017, a private standard on Privacy Impact Assessment explicitly referred to by EU Data Protection Authorities as relevant in the context of DPIA methods. The resulting gap analysis identifies and maps misalignments, critically reflecting on whether the parallel form of ISO regulation, in the context of DPIAs, could support or rather blurs GDPR's objective to protect fundamental rights by embracing a risks-based approach.
GDPR
Authors: Pikulík Tomáš , Štarchoň Peter
Published: May 2020

Implementation of the GDPR changed the way how personal data of EU customers are processed. The purpose of this chapter is to explore the links between the rights of customers as a data subject and related aspects of customer satisfaction. Entities in modern economy (encompassing not only goods and services but also intellectual property) generate and process huge quantities of customer data. Information and communication technology (ICT) infrastructure became a basis for the digital economy and society in the EU (settled by Eurostat as ISOC) that definitely replaced the previous era of the information economy that was based on the effective acquisition, dissemination, and use of information. Data-driven marketing puts data at the center of additional value creation and brings new insights and perspectives, included in the results of this research. The impact of GDPR on customer-centric ICT, stronger consumer awareness of data protection rights, creates new pathways to customer centricity and the legal and technical aspects of data processing within the digital economy ecosystem.
An Interdisciplinary Approach to Develop Linguistic Abilities in Bilingual Education
Authors: González Fernández Adela
Published: May 2020

The traditional methods of language teaching have always had their roots in the grammar-translation method, used in our educational system for more than 500 years. However, the constant search for updating and the desire to improve the language skills of students has led to a succession of different methods and proposals in a few years with the intention of improving the existing ones. The literature on this subject confirms that there is no perfect approach, but it also shows that the communicative one and the interdisciplinarity in the teaching-learning process of second languages brings good results. The author proposes a holistic interdisciplinary activity for the bilingual early childhood classroom, based on the communicative method. Thus, this chapter presents the elaboration of a musical tale, accompanied by a subsequent audiovisual recording, which will help students to learn a second language in real natural contexts.

Specific focuses of the chapter will delve into family dynamics, including various parenting styles and meta-emotion approaches, as they relate to affecting children's development. The chapter will also uncover the role of children's play interactions as they relate to how the activity itself fosters children's development as well as how play may be viewed as a vehicle in which to promote children's appreciation and understanding of diversity and multiculturalism. Specific program models typically seen within early learning classrooms and standards created by the National Association for the Education of Young Children (NAEYC) will be discussed in this chapter.
Teachers' Perceptions Towards Technology Integration Into Inclusive Early Childhood Education
Authors: Utami Athifah , Hidalgo Francisco Javier Palacios
Published: May 2020

The use of technology in formal and informal education is anything but new. It is easy to find it being integrated into primary, secondary, and higher education, yet few studies discuss how it can enhance the teaching/learning process in early childhood education, especially in the case of students with special needs. This chapter aims to explore teachers' attitudes on technology integration into inclusive early childhood education. To do so, a case study is described using data collected through classroom observation of five English-language lessons, as well as surveys and interviews administered to teachers of a private kindergarten school in Spain. Results show that most of the surveyed teachers have positive attitudes towards the use of technology in their classrooms and have already tried to implement it. Additionally, two main challenges are revealed: choosing suitable applications for children and maintaining their attention when using technological devices in the classroom.
To Develop the Sense of Activity Through Play in Children With Autism Spectrum Disorders
Authors: del Toro Alonso Víctor , Jiménez-Astudillo Mónica , Gutiez-Cuevas Pilar
Published: May 2020

Play is an ideal tool for enhancing the development of children with autism spectrum disorders (ASD). It is important to know their possibilities and to develop play activities that permit the special educational needs of these children to be addressed in an adequate way. Therefore, a case study is presented with two children and a two-year follow-up period during which the authors observe which aspects the development has evolved and if it is possible to increase the sense of the activity in these children using play as an educational response. The results are accompanied by an in-depth interview with the teachers of the students over the two-year period. An improvement in areas of development is evidenced in the social, communicative, symbolic, and anticipation and flexibilization dimensions during the two years immersed in a play methodology, supported by the structuring of routines and task spaces. Also, an evolution of the sense of the activity and the development of functional play is observed.
Delivering Integrated Early Childhood Education and Development Through Family in Focus
Authors: Tshishonga Ndwakhulu Stephen
Published: May 2020

This chapter explores the potential of home-based early childhood education in democratizing the sector especially for poor and disadvantaged children. Considering the huge number of children not accessing early learning centers, alternative ECD is optional. Family in Focus is one of the alternative ECDs formed in 1987 to cater for the needs of the poor and vulnerable children in the Western Cape Province. The focus of this programme is on the family as the primary source of care of young children. Through the FIF programme, home visitors are trained and supported to reach out to these children and their caregivers in order to develop the skills and capacity of caregivers to stimulate and develop their children effectively in their own homes. The chapter argues that the introduction of Family in Focus (FIF) as an alternative ECD programme could serve as a strategy to make ECD accessible to poor and disadvantaged communities.

An Expanded Framework for Facilitating Learner Autonomy and Enhancing Intrinsic Motivation Through Specifically-Designed Online Tasks
Authors: Koruyan Kasim
Published: May 2020

This chapter addresses the research gap in providing an extended framework for facilitating learner autonomy and enhancing intrinsic motivation through specifically-designed online tasks to enhance the development of reading skills in higher education. The approach to designing the reading tasks was informed by the comprehensive expansion of Chapelle's model explicitly to provide a theoretical framework for task design to assess the impact of the iPad-enhanced task design on the development of learner autonomy and motivation. Data collection and processing followed an exploratory case study approach applying mixed-method design. The differences in median scores for pre- and post-data were statistically tested using a Mann-Whitney U test. Thematic analysis was used to identify, analyze, and report themes in qualitative data collected for this study. Analysis of the results suggests that changing the culture of instruction and preparing university students for the realities of the digital age seem to be both positive and necessary.

The results of this study indicated that the online training course on mobile technologies had a positive impact on the use of ICT skills and EFL teachers' views in general. Further, attending the mobile technologies course delivered online was very beneficial and effective for the instructors in that it helped them to develop their skills on the use of mobile technologies in English language teaching.
Evaluation of Moodle, Canvas, Blackboard, and Open EdX
Authors: Öztürk Yunus Emre , Gürler İsmail
Published: May 2020

The digital world abolishing all the limitations to reach knowledge and removing the borders of the countries and even continents serves as a facilitator for everyone who wants to learn and reach knowledge. The growing demand for knowledge throughout the world also increases the need for a variety of courses from highly appreciated institutions and instructors in the most effective educational methods and techniques. Therefore, deciding which substructure or platform to be chosen by both enterprises to make a profit and learners to acquire knowledge in the most suitable way is becoming a more challenging issue for both counterparts of teaching and learning. In order to make this selection process easy, based on the document analysis method, this chapter presents an evaluative report on globally popular e-learning platforms including Canvas, Blackboard, Moodle, and Open edX in terms of their market share, user interface, feature strengths and weaknesses, and it reaches a conclusion by comparing and contrasting their differences and similarities.
Robots
Authors: Laukyte Migle
Published: May 2020

More and more often legal scholars notice that developments in robotics are becoming increasingly relevant from a legal point of view. This chapter critically assesses the current debate in the regulation of artificial intelligence (AI)-based robotics, whose scope should be seen as part of a wider debate that concerns AI. Indeed, what interests legal scholars are those robots that are able to act autonomously and intelligently, that is, robots embedded with AI. The chapter looks at such robots from the twofold perspective: on the one hand, robot as a product (and therefore the chapter refers to consumer protection) and, on the other hand, robot as entity (and therefore it addresses robot rights). The chapter also includes a brief overview of some of the initiatives to regulate AI and robotics interpreting the nuances so as to extract some ideas on national priorities in this regard.
A Matter of Perspective
Authors: Miller Katie
Published: May 2020

The challenge presented is an age when some decisions are made by humans, some are made by AI, and some are made by a combination of AI and humans. For the person refused housing, a phone service, or employment, the experience is the same, but the ability to understand what has happened and obtain a remedy may be very different if the discrimination is attributable to or contributed by an AI system. If we are to preserve the policy intentions of our discrimination, equal opportunity, and human rights laws, we need to understand how discrimination arises in AI systems; how design in AI systems can mitigate such discrimination; and whether our existing laws are adequate to address discrimination in AI. This chapter endeavours to provide this understanding. In doing so, it focuses on narrow but advanced forms of artificial intelligence, such as natural language processing, facial recognition, and cognitive neural networks.

Published: May 2020

The data-sponsored scheme allows the content provider to cover parts of the network subscription fees for end-users. As sponsored data gains traction in the industry, it is important to understand its implications. This work considers content providers (CP) choice of how much content to sponsor and the implications for end-users and CPs. In particular, the authors model the interactions of CPs as a non-cooperative game in terms of pricing, the credibility of content, and the amount of sponsored content. Additionally, they have proved through a detailed analysis of the existence and uniqueness of the Nash equilibrium. Based on the game properties, they implement a learning scheme using best-response dynamics that allows CPs to learn their strategies in a fast, accurate, yet completely distributed fashion. Extensive simulations provide attractive insights on how the sponsoring content may increase the CPs payoff.
Emerging Technology and Today's Libraries

Published: May 2020

The purpose of this chapter is to examine emerging technology and today's libraries. New technology stands out first and foremost given that they will end up revolutionizing every industry in an age where digital transformation plays a major role. Major trends will define technological disruption. The next-gen of communication, core computing, and integration technologies will adopt new architectures. Major technological, economic, and environmental changes have generated interest in smart cities. Sensing technologies have made IoT possible, but also provide the data required for AI algorithms and models, often in real-time, to make intelligent business and operational decisions. Smart cities consume different types of electronic internet of things (IoT) sensors to collect data and then use these data to manage assets and resources efficiently. This includes data collected from citizens, devices, and assets that are processed and analyzed to monitor and manage, schools, libraries, hospitals, and other community services.
Outline of Border Relations Between Mexico and the United States
Authors: Sandoval Alejandro Monjaraz
Published: May 2020

This chapter bases its premise on the fact that US foreign policy becomes a reality with certain areas of opportunity, dictated from the presidency, as it promotes unilateral policies focusing on migration from Mexico, securitization and militarization of the border, and the development of an economic strategy. Unfortunately, this defense of interests unilaterally has caused border states and municipalities to set their own objectives, development plans, and border and binational diplomacy and policy decisions and strategies.

Authors: Lee Soon Li , Tam Cai Lian
Published: May 2020

The present research was conducted to systematically review existing research that examined the relationships of the aspects of self-construal and social network sites (SNS) usages. A total of 12 research articles met the inclusion criteria for the present review. The reviewed research articles mainly supported the significant relationship of the interdependent self-construal and SNS-related outcomes. The present review highlighted that the reviewed relationships differed. Some findings supported the direct effect of self-construal on SNS-related outcomes, whereas some supported the indirect effects of intervening variables on these relationships. The reviewed findings supported the influence of self-construal on cognition, emotion, and motivation. Implications of the present systematic review were discussed in the manuscript.
Understanding How Chinese Consumers Engage in Electronic Word-of-Mouth Communication (eWOM) on Social Media
Authors: Wang Yuan
Published: May 2020

Examining a sample of 510 Chinese movie consumers, this study found that social benefits, utilitarian, venting negative feelings, and entertainment are the main reasons that motivate consumers to engage in eWOM activities. In addition, though social media offers consumers an equal access to participate in eWOM communication, people with higher opinion leadership can make better use of ICTs. They showed stronger trust on eWOM information, more willing to seek for and contribute eWOM content, and gratifying more from participating in eWOM activities on social media.
The Australian National Disability Insurance Scheme and People With Disabilities From CALD Backgrounds
Authors: Adibi Hossein
Published: May 2020

The National Disability Insurance Scheme (NDIS) is considered to be the second greatest reform in healthcare in Australia after the introduction of Medicare in Australia in 1983. This reform was introduced in 2012 in two phases. The first phase as a trial took place for three years. The expectation was that the reform will be rolled out by 2019 or 2020. This article argues that the trial implementation process has achieved very positive outcomes in the lives of a great number of people with disability in Australia. At the same time, NDIS is facing many serious challenges in some areas. One of the obvious challenges is that this reform is a market approached reform. The second challenge relates to meeting the needs of minorities. People with disabilities from Culturally and Linguistically Divers (CALD) backgrounds are one of the five most venerable, underutilised users of NDIS services in Australia. They have no strong voice and negotiable abilities. The main question here is how NDIS is to meet its commitment to satisfy the needs of these vulnerable people in Australia.

In this work, a new microwave dielectric material for LTCC applications,xAl2O3+ (1-x) BaO-Al2O3-B2O3-SiO2-ZnO (x=0.3, 0.4, 0.5 and 0.6) glass-ceramics, was synthesized. The effect of Al2O3on the microstructure, mechanical properties and electrical properties of BaO-Al2O3-ZnO-B2O3-SiO2glass-ceramics was studied in this paper. The crystallinity was studied by jade6.5 software using the whole pattern fitting method. The XRD analysis showed that the content of BaAl2Si2O8increased first and then decreased with the increase of Al2O3content. It is found that the formation of phase BaAl2Si2O8contributes to strong bending strength. ThexAl2O3+ (1-x) BaO-Al2O3-SiO2-ZnO-B2O3glass-ceramics sintered 2h at 920°C has the excellent microwave dielectric properties atx=0.4,εr=7.4,tanσ=1.49×10-3at 13.5GHz,τf=-42.67ppm/°C, flexural strength= 184MPa.

Acetone is a main respiratory marker for diabetic patients. In this paper, P-type NiO nanofibers were prepared by electrospinning and used for the detection of acetone gas. NiO nanofibers were characterized by SEM and XRD. The uniform NiO nanofibers with face-centered cubic structure was obtained. The working temperature of NiO nanofibers was optimized, and the optimal operating temperature is 220°C. The response-recovery curve was tested, and the response and recovery time is 24.6 s and 610 s respectively. The response to different concentrations of acetone was also analyzed, and the detection limit was 100 ppb. These results show that NiO nanofibers based on electrospinning have potential applications in the respiratory testing of diabetes.

Published: May 2020

Three-dimensional (3D) network structure has been recognized as an efficient approach to enhance the mechanical and thermal conductive properties of polymeric composites. However, it has not been applied in energetic materials. In this work, a fluoropolymer based composite with vertically oriented and interconnected 3D graphite network was fabricated for polymer bonded explosives (PBXs). Here, the graphite and graphene oxide platelets were mixed, and self-assembled via rapid freezing and using crystallized ice as the template. The 3D structure was finally obtained by freezing-dry, and infiltrating with polymer. With the increasing of filler fraction and cooling rate, the thermal conductivity of the polymer composite was significantly improved to 2.15 W m-1 K-1 by 919% than that of pure polymer. Moreover, the mechanical properties, such as tensile strength and elastic modulus, were enhanced by 117% and 563%, respectively, when the highly ordered structure was embedded in the polymer. We attribute the increased thermal and mechanical properties to this 3D network, which is beneficial to the effective heat conduction and force transfer. This study supports a desirable way to fabricate the strong and thermal conductive fluoropolymer composites used for the high-performance polymer bonded explosives (PBXs).

Published: May 2020

The CeO2/rGO composites were prepared by hydrothermal method. The microscopic phase structure and microstructure of the samples were characterized by SEM, XRD and FTIR. The cyclic voltammetry (CV) and constant current charge and discharge tests were used to study the electrochemical stability and cycle ability of the CeO2/rGO composite electrode. The results show that the incorporation of graphene effectively increases the reversibility of CeO2 as an electrode material. The special structure of graphene provides a continuous network and more active sites for redox reactions. In the 6mol/L KOH electrolyte, the specific capacitance of CeO2/rGO composite reached 114F·g-1 when the current density was 0.5A/g. After 1000 cycles, the specific capacitance only decreased by 12.66%, which proves that this material has good cycle performance.

Published: May 2020

Thermal degradation of the composite constituted by high density polyethylene (HDPE) and microencapsulated red phosphorus (MRP) were studied using thermogravimetric (TG) data obtained at different heating rates. The kinetic models and parameters of the thermal degradation of MRP/HDPE composite were evaluated by FWO, KAS and IKP method. It indicates that the activation energy E of 4 % MRP/HDPE composite is higher than HDPE for three methods. MRP could improve the thermal stability and slow down the thermal degradation of HDPE. With adding MRP, the degradation mechanism of HDPE is changed and the degradation rate decreases.
AN ATTACK ON A CICADA BY POLISTES RUBIGINOSUS
Authors: O'Byrne Harold
Published: May 2020

According to Ashmead (1896) and others, the wasps belonging to the genus
Polistes usually feed their young chewed-up
fragments of lepidopterous larvae. However, Riley (1873) mentions
P. rubiginosus Lept. as one of the natural
enemies of the Colorado potato beetle, Leptinotarsa
decemlineata Say, whose larvae it carries to its nest. A
varied diet is therefore to be expected in these wasps. Nevertheless, I was
very much surprised when I came across a
rubiginosus engaged in a violent struggle
with a large cicada (identified as Tibicen
auletes Germ. by Mr. William T. Davis), at Ranken,
Missouri, on July 19, 1932.
