Published: January 2019

Background: Alpinia officinarum Hance is both an herbal medicine and a condiment, and generally has different cultivars such as Zhutou galangal and Fengwo galangal. The appearance of these A. officinarum cultivars is similar, but their chemical composition and quality are different. It is therefore important to discriminate between different A. officinarum plants to ensure the consistency of the efficacy of the medicine. Therefore, we used an electronic nose (E-nose) to explore the differences in odor information between the two cultivars for fast and robust discrimination. Methods: Odor and volatile components of all A. officinarum samples were detected by the E-nose and gas chromatography-mass spectrometry (GC-MS), respectively. The E-nose sensors and GC-MS data were analyzed respectively by principal component analysis (PCA), the correlation between E-nose sensors and GC-MS data were analyzed by partial least squares (PLS). Results: It was found that Zhutou galangal and Fengwo galangal can be discriminated by combining the E-nose with PCA, and the E-nose sensors S2, S6, S7, S9 were important sensors for distinguishing different cultivars of A. officinarum. A total of 56 volatile components of A. officinarum were identified by the GC-MS analysis, and the composition and content of the volatile components from the two different A. officinarum cultivars were different, in particular the relative contents of 1,8-cineole and α-farnesene. The classification result by PCA analysis based on GC-MS data was consistent with the E-nose results. The PLS analysis demonstrated that the volatile terpene, alcohol and ester components primarily interacted with the sensors S2 and S7, indicating that particular E-nose sensors were highly correlated with some aroma constituents. Conclusions: Combined with advanced chemometrics, the E-nose detection technology can discriminate two cultivars of A. officinarum, with GC-MS providing support to determine the material basis of the E-nose sensors’ response.

Published: January 2019

Soil moisture is an important aspect of heat transfer process and energy exchange between land-atmosphere systems, and it is a key link to the surface and groundwater circulation and land carbon cycles. In this study, according to the characteristics of the study area, an advanced integral equation model was used for numerical simulation analysis to establish a database of surface microwave scattering characteristics under sparse vegetation cover. Thus, a soil moisture retrieval model suitable for arid area was constructed. The results were as follows: (1) The response of the backscattering coefficient to soil moisture and associated surface roughness is significantly and logarithmically correlated under different incidence angles and polarization modes, and, a database of microwave scattering characteristics of arid soil surface under sparse vegetation cover was established. (2) According to the Sentinel-1 radar system parameters, a model for retrieving spatial distribution information of soil moisture was constructed; the soil moisture content information was extracted, and the results were consistent with the spatial distribution characteristics of soil moisture in the same period in the research area. (3) For the 0–10 cm surface soil moisture, the correlation coefficient between the simulated value and the measured value reached 0.8488, which means that the developed retrieval model has applicability to derive surface soil moisture in the oasis region of arid regions. This study can provide method for real-time and large-scale detection of soil moisture content in arid areas.

Published: January 2019

Cultivation of yams by rural households contributes to food supply and income generation. Notwithstanding the importance of this crop, yam production has been stagnating, threatening rural livelihoods and food security. Contrary to traditional yam systems in Ghana, an alternative system that integrates pigeonpea and yam is being proposed to mitigate constraints in existing yam production system through replenishing soil fertility, the provision of stakes for staking, and providing nutritious grains to farmers. The purpose of this study was to explore farmers’ constraints and determine farmers’ knowledge of the pigeonpea–yam cropping system. The investigation was conducted using structured questionnaires on a sample consisting of 150 yam farmers from three major yam-producing districts of Ghana. Results revealed that access to capital, mechanization, and poor road network were among the main constraints that militated yam production. A majority (68%) farmers are also still using shifting cultivation in search of fertile lands for yam production. The study found that farmers had poor knowledge of the pigeonpea–yam cropping system and the benefits and uses of pigeonpea. Given the potential of the pigeonpea–yam intercropping system in addressing soil fertility and providing a readily available source of stakes, it would be a viable option for smallholder farmers to increase and sustain production.
Impact of Sycamore Maple Thermal Treatment on a Granulometric Composition of Chips Obtained due to Processing on a CNC Machining Mentre

Published: January 2019

This article deals with a granulometric composition of chips from the milling process of native and thermal treatment maple cuttings on a 5-axial Computer numerical control (CNC) machining center SCM Tech Z5. The aim of this article was to determine the changes in the granulometric composition of chips due to the thermal treatment of wood and to assess the potential risk of the creation of harmful dust fractions. Cuttings were milled with a shank cutter with exchangeable razor blades at feed speed vf = 1 ÷ 5 m·min−1 and material removal e = 3 mm. The thermal treatment in order to modify the color of the maple wood was done with water vapour at temperatures of tI = 112.5 ± 2.5 °C for a period of τ = 5.5 h (Mode I), tII = 127.5 ± 2.5 °C for a period of τ = 6.5 h (Mode II), and tIII = 137.5 ± 2.5 °C for a period of τ = 7.5 h (Mode III). The granulometric composition of the chips was detected by sifting. A granulometric analysis of the chips provided that more than 2/3 of the produced chips are a coarse fraction consisting of flat chips with dimensions over 1 mm. Dust fractions smaller than 500 μm form isometric grains, i.e., chips having approximately the same size in all three dimensions. Inhalable dust particles, smaller than 125 μm, do not exceed a 2.5% share. The granulometric analysis of chips shows that the thermal treatment of maple wood does not create respirable fractions, and therefore, the thermal treatment of the wood does not have a negative impact on the living and working environments.
Regional Economic Resilience of the Old Industrial Bases in China—A Case Study of Liaoning Province
Authors: Li Liangang , Zhang Pingyu , Li Xin
Published: January 2019

Regional economic resilience provides a new perspective for explaining regional differences in response to recession shocks. This paper analyzed the regional economic resilience of Liaoning Province in China in terms of its resistance and recoverability dimensions from 1990 to 2015 and explored the determinants of regional economic resilience by constructing a spatial econometric model using panel data. There are three main findings. First, the level of regional economic resilience in Liaoning was low and its urban economy was more vulnerable to external shocks than that of the whole nation. Second, we found that factors such as the local governance arrangement, the regional innovation ability, and the level of economic diversification have significant positive effects on regional economic resilience. Factors such as the proportion of secondary industry and the GDP negatively affect regional economic resilience. Third, regional economic resilience demonstrates a spatial autocorrelation, and the improvement of economic resilience in the surrounding areas will lead to the decline of regional economic resilience.

Published: January 2019

The objective of the present study is to achieve a better understanding of the possible rotation of embayed beaches using shoreline position data from two beaches on the central Tyrrhenian Sea (Italy) during a 64-year period. With this aim, this study tests the utility of Differential Global Positioning System (DGPS) and GPS RTK (Real Time Kinematic) dual-frequency navigation system for the in situ surveys, low-altitude aerial imagery collected by Unmanned Aerial Vehicle (UAV), and satellite polarimetric Synthetic Aperture Radar (SAR) measurements. The dataset consists of aerial photographs and orthophotos, DGPS, and remote surveys performed by UAV and SAR platform in 2018 along with wave data coming from the Ponza buoy. The results of the field data analysis explained a part of the beach variations in terms of coastline rotation around a virtual pivotal point. This rotation has been correlated with the wave directional shift in the recent period. The results of the comparison between the different techniques gave the possibility to investigate the limitations of remote survey methods for the identification of shoreline rotation.
Winner-Takes-All or Co-Evolution among Platform Ecosystems: A Look at the Competitive and Symbiotic Actions of Complementors
Authors: Inoue Yuki
Published: January 2019

Technological platforms such as hardware or systems form platform ecosystems, which are communities orchestrated by platform providers, outside complementors such as software providers, and consumers. Previous studies have suggested that a winner-takes-all situation among platform ecosystems could be induced by interactions between complementors and consumers. However, our observation of the Japanese video game market over the last 30 years indicated that complementors (i.e., software providers) usually seek to avoid winner-takes-all situations and, instead, promote symbiotic situations. Using the Lotka–Volterra equations from biology as a reference, we developed a model to understand the competitive behavior of complementors among platform ecosystems. We used a 19-year (1996–2015) dataset on the Japanese video game market and confirmed that complementors took as many actions to create symbiotic situations as they took to create winner-takes-all situations, if not more. Our results show that such actions by complementors are influenced by several factors of platform ecosystems. This study also suggests that certain complementors that contribute to symbiotic co-existence within a platform ecosystem could emerge as keystone firms/companies. These complementors could contribute to the sustainability of platform-based markets and facilitate the co-existence of multiple platform ecosystems.
Bicycle Sharing: Sustainable Value Creation and Institutionalisation Strategies in Barcelona
Authors: Winslow Julia , Mont Oksana
Published: January 2019

A highly debatable issue is whether or not a paradigm shift toward the sharing economy could help to address the economic, social and environmental challenges of our time. This article contributes to the academic discussion by exploring the types of value created by sharing organisations and the strategies they use to institutionalise themselves in relation to powerful institutions. The study applies two analytical frameworks, based on value creation and institutional strategies, to three empirical case studies of bicycle sharing systems (BSS) in Barcelona. Rich data was collected from a variety of primary and secondary sources, including a field visit to Barcelona, interviews with representatives of the three bicycle sharing systems, observations and literature analysis. We found that the environmental value these organisations create is closely interlinked with the social value they produce and that these values outweigh negative impacts of their operations. All case organisations employ regulative, normative and cultural-cognitive strategies for their institutionalisation but are also subject to powerful institutions beyond their individual control. We recommend that entrepreneurs, city officials, the public and other stakeholders engage in collaborative and open development processes to shape the emerging sharing economy alongside the institutional work of sharing organisations.
A Comparison of Neighborhood-Scale Interventions to Alleviate Urban Heat in Doha, Qatar

Published: January 2019

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the research indicates that at the neighborhood scale, the most effective scenario was that of adding mature trees along the sides of roads. In the coastal study area, the model results estimated a maximum hourly air temperature reduction of 1.35 °C, and in the highly urbanized inland site, surface temperature reductions were up to 15 °C at 12:00. While other scenarios were effective at reducing air and surface temperatures, the mean radiant temperature was also increased or nearly neutral for most of the other scenarios. This result highlights the need to develop improved shading measures for pedestrian pathways and outdoor recreational areas, especially for highly urbanized inland areas in Doha and cities with similar climatic conditions.
EXPLORING THE COMPLEMENTARITY BETWEEN FOREIGN TECHNOLOGY, EMBEDDED TECHNOLOGY AND INCREASE OF PRODUCTIVE CAPACITY
Authors: González-Blanco Jennifer , Vila-Alonso Mercedes , Guisado-González Manuel
Published: January 2019

This study analyzes the complementarity of foreign technology acquired under license agreements, technology embedded in machinery and equipment and increase in a company’s productive capacity. We use panel data on Brazilian manufacturing companies from the World Bank Surveys. We used the random effects models, estimated by maximum likelihood. The results indicate that foreign technology, embedded technology and increase of productive capacity have a positive and significant impact on labor productivity. The complementarity test reveals that the relationship between the two technologies analyzed is conditionally substitutive and that the relationship between each of these technologies and increase of productive capacity is conditionally complementary.
High Confidence Optical Confirmations among the High Signal-to-noise Planck Cluster Candidates

Published: January 2019

We report on newly identified galaxy clusters from the high signal-to-noise (>5σ) end of the second all-sky Planck Sunyaev–Zel’dovich (SZ) catalog (PSZ2). The clusters are identified in deep, optical imaging from the Kitt Peak National Observatory 4 m Mayall telescope taken between 2014 and 2017. Here we focus on the highest richness systems, and identify galaxy clusters through a combination of the maxBCG algorithm and visual image inspection. Galaxy clusters are considered to be confirmed if they are both rich and spatially coincident (≲6′) with the reported PSZ2 position. Of the 85 fields containing unconfirmed PSZ2 candidates observed, we find 15 (17.6% of the observed sample) corresponding galaxy clusters (0.13 < z < 0.78), 12 of which are previously unrecognized as counterparts. To explain this low identification fraction, we consider three possible scenarios: that clusters are (1) mostly at low-z, (2) mostly at high-z, or (3) located in fields with high object density. None of these scenarios alone can account for the low purity of rich galaxy clusters among the high signal-to-noise PSZ2 unconfirmed candidates.

Active solar-type stars show large quasi-periodic brightness variations caused by stellar rotation with star spots, and the amplitude changes as the spots emerge and decay. The Kepler data are suitable for investigations of the emergence and decay processes of star spots, which are important to understand the underlying stellar dynamo and stellar flares. In this study, we measured the temporal evolution of the star-spot area with Kepler data by tracing the local minima of the light curves. In this analysis, we extracted the temporal evolution of star spots showing clear emergence and decay without being disturbed by stellar differential rotation. We applied this method to 5356 active solar-type stars observed by Kepler and obtained temporal evolution of 56 individual star spots. We calculated the lifetimes and emergence/decay rates of the star spots from the obtained temporal evolution of the spot area. As a result, we found that the lifetimes (T) of star spots range from 10 to 350 days when the spot areas (A) are 0.1%–2.3% of the solar hemisphere. We also compared them with sunspot lifetimes and found that the lifetimes of star spots are much shorter than those extrapolated from an empirical relation of sunspots (T ∝ A), while being consistent with other research on star-spot lifetimes. The emergence and decay rates of star spots are typically 5 × 1020 Mx hr−1 (8 MSH hr−1) with an area of 0.1%–2.3% of the solar hemisphere and mostly consistent with those expected from sunspots, which may indicate the same underlying processes.

We present the results from a pilot study with the Karl G. Jansky Very Large Array to determine the radio morphologies of extended radio sources and the properties of their host-galaxies in 10 massive galaxy clusters at z ∼ 1, an epoch in which clusters are assembling rapidly. These clusters are drawn from a parent sample of WISE-selected galaxy clusters that were cross-correlated with the VLA Faint Images of the Radio Sky at Twenty-Centimeters survey to identify extended radio sources within 1′ of the cluster centers. Out of the 10 targeted sources, 6 are FR II sources, 1 is an FR I source, and 3 have undetermined morphologies. Eight radio sources have associated Spitzer data, 75% presenting infrared counterparts. A majority of these counterparts are consistent with being massive galaxies. The angular extent of the FR sources exhibits a strong correlation with the cluster-centric radius, which warrants further investigation with a larger sample.
Rotating Halo Traced by the K-giant Stars from LAMOST and Gaia
Authors: Tian Hao , Liu Chao , Xu Yan , Xue Xiangxiang
Published: January 2019

With the help of Gaia DR2, we are able to obtain the full 6D phase space information for stars from the Large Sky Area Multi-Object Fibre Spectroscopic Telescope DR5. With high precision of the position, velocity, and metallicity, the rotation of the local stellar halo is presented using the K-giant stars with [Fe/H] < −1 dex within 4 kpc from the Sun. By fitting the rotational velocity distribution with the three-Gaussian components, stellar halo, disk, and counterrotating hot population, we find that the local halo progradely rotates with

km s−1, providing the local standard of the rest velocity of V
LSR = 232 km s−1. Meanwhile, we obtain the dispersion of rotational velocity is

km s−1. Although the rotational velocity strongly depends on the choice of V
LSR, the trend of prograde rotation is substantial even when V
LSR is set at as low as 220 km s−1. Moreover, we derive the rotation for subsamples with different metallicities and find that the rotational velocity is essentially not correlated with [Fe/H]. This may hint at a secular evolution origin of the prograde rotation. It shows that the metallicity of the progradely rotating halo is peaked within −1.9 < [Fe/H] < −1.6 without considering the selection effect. We also find a small fraction of counterrotating stars with larger dispersion and a lower metallicity. Finally, the disk component rotates with

km s−1 and

km s−1, which is quite consistent with the metal-weak thick disk population.

UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM Cephei is such a UXor in the young (∼4 Myr) open cluster Trumpler 37, showing prominent infrared excess, emission-line spectra, and flare activity. Our photometric monitoring (2008–2018) detects (1) an ∼3.43 day period, likely arising from rotational modulation by surface starspots, (2) sporadic brightening on timescales of days due to accretion, (3) irregular minor flux drops due to circumstellar dust extinction, and (4) major flux drops, each lasting for a couple of months with a recurrence time, though not exactly periodic, of about two years. The star experiences normal reddening by large grains, i.e., redder when dimmer, but exhibits an unusual “blueing” phenomenon in that the star turns blue near brightness minima. The maximum extinction during relatively short (lasting ≤50 days) events, is proportional to the duration, a consequence of varying clump sizes. For longer events, the extinction is independent of duration, suggestive of a transverse string distribution of clumps. Polarization monitoring indicates an optical polarization varying ∼3%–8%, with the level anticorrelated with the slow brightness change. Temporal variation of the unpolarized and polarized light sets constraints on the size and orbital distance of the circumstellar clumps in the interplay with the young star and scattering envelope. These transiting clumps are edge-on manifestations of the ring- or spiral-like structures found recently in young stars with imaging in infrared of scattered light, or in submillimeter of thermalized dust emission.
Blue Straggler Stars beyond the Milky Way. IV. Radial Distributions and Dynamical Implications

Published: January 2019

Blue straggler stars (BSSs) have been proposed as powerful indicators to measure the dynamical state of Galactic globular clusters (GCs). Here we examine for the first time whether this framework of BSSs as dynamical clocks, which was specifically developed for Galactic GCs, may also hold for younger GCs in the Large Magellanic Cloud (LMC). Using Hubble Space Telescope observations, we study seven LMC star clusters with ages between ∼700 Myr and 7 Gyr. We confirm that our sample clusters are consistent with the empirical correlation previously derived for Galactic GCs, within a modest tolerance. We suggest that to further examine whether BSSs can measure the dynamical state of their host clusters over an extended range of dynamical ages, more studies of dynamically older Magellanic Cloud clusters are required. We discuss the physical implications of our results in terms of their central, dimensionless King potential, as well as the initial retention fraction of black holes.

Fluctuating antenna model: Applications and prospects
Authors: Trinkūnas Gediminas , Chmeliov Jevgenij
Published: January 2019

Recently, we proposed a simple conceptual fluctuating antenna model (FAM), describing excitation diffusion and trapping in a continuous medium, where variations of the excitation transfer pathways are taken into account by the introduced fractional space dimension. Since then, this model has been successfully applied to simulate multi-exponential excitation quenching kinetics in a series of plant photosynthetic systems, purified from the thylakoid membranes, without invoking a radical pair state in the reaction centre. Here, we overview this model and its parameters obtained for various systems, and extend the area of its applications to several pigment–protein supercomplexes containing the photosystem I (PSI). We show that while the diffusion in the PSI core is virtually three-dimensional, the PSI core aggregates interconnected with other light-harvesting complexes (LHCI and/or LHCII) are characterized by a substantially reduced dimension, which indicates a smaller number of energy transfer links from LHCI to the PSI core. We also suggest that in vivo both PSI and PSII antennae are substantially larger than those observed in the isolated systems: PSII antenna contains in total about 6 LHCII trimers while PSI is aggregated with at least one LHCII trimer. The obtained results show that FAM can be a very useful tool to follow photosynthetic apparatus transformations during short- and long-term adaptation to varying light, monitored by kinetic fluorescence spectroscopy.
Learning Effect of Implicit Learning in Joining-in-type Robot-assisted Language Learning System
Authors: Khalifa AlBara , Kato Tsuneo , Yamamoto Seiichi
Published: January 2019

The introduction of robots into language learning systems has been highly useful, especially in motivating learners to engage in the learning process and in letting human learners converse in more realistic conversational situations. This paper describes a novel robot-assisted language learning system that induces the human learner into a triad conversation with two robots through which he or she improves practical communication skills in various conversational situations. The system applies implicit learning as the main learning style for conveying linguistic knowledge, in an indirect way, through conversations on several topics. A series of experiments was conducted using 80 recruited participants to evaluate the effect of implicit learning and the retention effect in a joining-in-type robot-assisted language learning system. The experimental results show positive effects of implicit learning and repetitive learning in general. Based on these experimental results, we propose an improved method, integrating implicit learning and tutoring with corrective feedback in an adaptive way, to increase performance in practical communication skills even for a wide variety of proficiency of L2 learners.

With the rapid development of information technology, 3D game technology also has developed gradually. Virtual reality technology is developing at a fast speed, too. At present, virtual teaching method of game design in software engineering major may be caught in the unfavorable situation where “teachers do not respect it and students’ learning motivations differ a lot”. Meanwhile, students may be easily influenced by nonintellectual factors such as emotion, hobby and will, and develop many harmful learning habits such as indifference to standards of game development procedure, which to certain degree influences teaching effect. On this basis, the teaching method of applying educational game development theory in game design course was proposed in this study. First of all, research status of domestic and overseas game design courses was analyzed. Starting from education and 3D software features, the content of Game Design in software engineering major was chosen for educational game design and development. Meanwhile, questionnaire survey and experiment were carried out to evaluate the application effect of the case. It was found that, educational game designed in this study was affirmed by students and teachers, and the case gained a favorable effect in the implementation process. Besides, game-based teaching method motivated students’ learning interest. In conclusion, the teaching effect of educational game is better than traditional teaching effect.

Las “tapisseries chiliennes” de Violeta Parra entre lo vernáculo y lo internacional.
Authors: Plante Isabel
Published: January 2019

A cien años del nacimiento de Violeta Parra, lo popular continúa teniendo un lugar central en los estudios sobre su obra. ¿Cómo pensar de manera específica los vínculos con las culturas vernáculas para el caso de su producción visual? Este artículo se propone, por un lado, analizar algunas de sus obras a partir de su materialidad, características estilísticas, temas y motivos. Y por otro lado, reconstruir la circulación pública de sus pinturas y arpilleras, cuyo momento consagratorio fue la exhibición parisina de 1964 en el Musée des Arts Décoratifs. Y así articular la trayectoria de Violeta –esto es los lugares donde produjo, mostró y vendió su obra visual– con el rastreo de tradiciones locales técnicas y materiales utilizadas en su propia producción. En este sentido, se pretende considerar lo vernáculo y lo internacional, lo popular y lo moderno como nociones interconectadas a partir de las cuales pensar situadamente la obra visual de Violeta Parra.

Published: January 2019

Standards are applicable to any kind of activity and could be defined, in a general way, as an activity aiming to apply an ordered system to repetitive functions that take place in the context of industry, technology, science, and economy. Auditing is deeply connected to the implementation of any standard, and this chapter aims to do its connection. Standardization can stimulate international comparability eliminating obstacles arising from some different national practices in accounting and in auditing using IFRS and ISA, in risk analysis using ERM or ISO 31000, in people's safety, in the product or in the environment. A case study about ISO 31000 in a municipality where IFRS and ISA are followed and ISO 9001, 14001, 18000 are a reality will frame this issue. ISO 26000 about corporate social responsibility will be the new future challenge.
An Overview on Mobile Cloud Computing
Authors: Santos Carlos , Inácio Helena , Marques Rui Pedro
Published: January 2019

Mobile cloud computing is a concept that has been gaining popularity, resulting from the synergistic integration of cloud computing and mobile computing with the goal of minimizing some of the limitations inherent in mobile computing (bandwidth, storage, autonomy, etc.) and giving greater plasticity to the services of the cloud computing providers. This new paradigm of computation has similar limitations to those associated with the paradigms that are at its origin. Therefore, it is essential that the research carried out in this area is concerned about understanding its impact on audit processes, which aim to verify and evaluate the mechanisms of the internal control system implemented to minimize threats to integrity, confidentiality, and availability of the information assets (data and/or information) stored on these platforms. Based on a literature review, this chapter aims to list a set of challenges associated with the adoption of mobile cloud computing within the scope of organizational auditing.

Published: January 2019

Organizations face a challenge on the emerging technology-enabled businesses to prevent fraud and mitigate risks. Information technology (IT) advancements also provided the possibility of ongoing risk assessment and ongoing control assessment on the growing data volume in the digital age. Although organizations perceive the benefits of continuous auditing (CA) and continuous monitoring (CM), its adoption is low. Some barriers limit CA and CM adoption along with common challenges that organizations must face during implementation.

Authors: Ortiz-Rodríguez David , Alcaide-Muñoz Laura , Flórez-Parra Jesús Mauricio , López-Hernández Antonio Manuel
Published: January 2019

One of the objectives of supreme audit institutions (SAIs) is to promote transparency and accountability of the public sector entities. But, at the same time, SAIs must improve their own transparency and accountability. The use of information and communication technologies plays an essential role in making this disclosure. The International Organization of the Supreme Audit Institution (INTOSAI) recognizes that communication is a strategic factor of SAIs. Studies have analyzed information dissemination practices carried out in developed countries. However, SAIs elsewhere, such as the Latin American and Caribbean, have not been the object of research. This chapter analyzes whether these SAIs are using the internet as a means to enhance transparency and interaction with stakeholders. The results indicate that, although in general the institutions analyzed publish the information required by INTOSAI, there is still ample room for improvement, especially regarding interaction with their stakeholders.

This chapter conducts an in-depth study regarding European football clubs' marketing strategies and brand management approaches in order to evaluate customers' perceived ethicality and how consumers value corporate social responsibility activities. Specifically, the case of European football clubs is evaluated during the 2013-2018 period. The evolution of the value of the top 20 football teams in 2013 were considered as they are the most valuable ones, and most renowned in terms of worldwide supporters and revenues. Furthermore, the success of the top three teams, Manchester United, FC Barcelona, and Real Madrid FC, were studied. The findings highlight how European football clubs should incorporate corporate social responsibility into their marketing strategy, combining it with their own players' approaches, in order to increase their value and reputation.
Thinking Outside the Box

At its core, inclusive education takes a great deal more than educators who follow a checklist of best teaching practices and procedures. It requires professionals philosophically committed to inclusion who effectively and efficiently co-plan and co-teach instruction to a diverse group of learners. Co-planning is one of the most important elements of co-teaching and inclusion, yet one of the hardest things to make time for amongst a busy school week. Within this chapter, the authors will discuss and analyze their co-planning and co-teaching models across two semesters of teaching a differentiation methods course to pre-service undergraduate teachers, specifically sharing about their successful utilization of a virtual platform for co-planning. The chapter will conclude with the positives and challenges of using a virtual planning platform, as well as specific recommendations for how to use one.
An Exploratory Study on Teacher Training
Authors: Fedeli Laura , Pennazio Valentina
Published: January 2019

Since 2012, the concept of “special training needs” in Italian ministerial legislation has been connected to the concept of inclusion. In the Italian school system, students with disabilities are fully integrated in standard school activities. They can take advantage of the presence of a teacher who is a supportive figure for the whole class, who has received training in inclusion and the management of teaching strategies for dealing with disabilities. In order to train teachers who will fit that profile, a specialization course is organized by Italian universities to train teachers at every level of instruction. The chapter is contextualized to the last course of academic year 2016-2017, which took place at the University of Macerata, addressed to preschool and primary teachers. Exploratory research using a qualitative approach was run to highlight, on one hand, student teachers' preconceptions and expectations about the effectiveness of technologies for inclusion; and, on the other hand, their opinions about the activities proposed during the technology course.
Evidence-Based Transition Practices
Authors: Soldner James L. , Peter Dimity , Sajadi Shahrzad , Paiewonsky Maria
Published: January 2019

Preparing youth to become active and independent citizens is a critical goal for all societies. However, youth with disabilities are less likely to achieve the same adult outcomes as their non-disabled peers. Although there is a growing body of research that has identified best practices regarding the facilitation of youth with disabilities from school to an inclusive adult life, many teachers do not have the requisite skills or knowledge to facilitate this process. This chapter explores best practices in transition education for teachers beyond the academic content, identifying eight key strategies that should inform teacher preparation programs. Using a case study from Iran, this chapter critically reflects on the relevance of these strategies in an international context, where inclusion and education of students with disabilities is an emerging field.
Inclusion and Exclusion
Authors: Scott Jessica Armytage , Dostal Hannah M. , Ewen-Smith Tisha N.
Published: January 2019

In this chapter, the authors explore the practice of inclusion as it relates to the education of deaf and hard of hearing (d/hh) students. Using the current situation in Jamaica as a microcosm, it is argued that for this specific population of students it may be necessary to reframe and redefine the notion of inclusion more broadly. For example, the authors argue that as a result of the specific cultural, linguistic, and academic needs of d/hh students, a more traditional approach to inclusion may in fact result in isolation and less access to content and skills. Inclusion that considers how deaf education classrooms may include accessible language, the Deaf community, families of d/hh children, and Deaf role models may be more appropriate for this population.
The Post-Material Values of Young People and Interactive Technologies in the Formation of a Culture of Scientific Dialogue in the Student Environment
Authors: Romanenko Inna Borisovna , Romanenko Yuriy Mikhailovich , Voskresenskiy Alexey Alexandrovich
Published: January 2019

The task of reforming and improving the social and humanitarian component of modern education is related to the understanding of time as an existential experience associated with the phenomenon of age. According to the theory of generations of N. Howe and W. Strauss, age is defined as a measure of awareness of one's own living life. It is a methodological approach of this study. The generations of Y and Z are the subject of special attention in the study being the group that actually forms the requests for the educational policy of the state. Considerable attention is paid to the formation of skills and culture of conducting scientific dialogue in the student environment (the development of certain norms of behavior, the adoption of the normative requirements for scientific dialogue, the assimilation of various formats for discussions, projective activities, etc.).
Visual Storytelling as Generative Strategy for Social Educators
Authors: Fedeli Laura
Published: January 2019

The chapter deals with the discussion of the results of an experimentation run in two consecutive academic years within the classes of the graduate course “Instructional Technology” in the graduate course “Science of Education” at the University of Macerata, Italy. The IT course is programmed in the third year of the curriculum for “Social Educators” and the contribution reports the results of a case study related to a workshop activity in which students could find a further opportunity to identify different dimensions of relation among theoretical aspects and the potential practical/applied connotations in professional contexts. The workshop was structured as an experiential learning process in which the value of the digital storytelling as educational approach was a strategy adopted to foster the students' understanding toward the intercultural issues in terms of improvement of relationship by taking a prospective position oriented to the other.
Technology of Conducting Group Training to Increase Communicative Competence for Teachers of Socio-Humanitarian Disciplines
Authors: Moskvicheva Natalia , Kostromina Svetlana
Published: January 2019

The authors present the training of increasing communicative competence for teachers of social and humanitarian disciplines. An overview of the current research in this area is given: the development of projects for training teachers with a communicative skill and the search for means to assess their effectiveness, the use of feedback and reflection, the use of active teaching methods. The necessity of an individualized approach aimed at self-knowledge of the teacher, the awareness of his individual style, personal characteristics, and motivation is substantiated. The theoretical basis of the training is based on the psychological understanding of the structure of the teacher's activity. The chapter details the goals, methods, the form of training, the necessary conditions, and the order of the training, which allow achieving the set goals and reproducibility of the results of training by other trainers. An approximate training plan, which includes six sessions, is described in detail. The results of the introduction of training and evaluation of its effectiveness are presented.
