    Full Text Available In this information and knowledge era; ICT development and industry are growing very fast and associated with huge procurement force. Today, the global society is facing serious challenges in improving environmental performance, particularly with climate change, global warming, and resource management. ICT industry is widely contributing to the global economy associating with innovation, invention and rapid development of almost all the aspect of human life. On other hand; ICT industry is responsible for global CO2 emissions. Global environmental problems are affecting directly many countries' energy and industrial policies. The rapid increasing of ICT usage means more energy consumption and more environmental problems and the estimated ICT consumption of energy will be about 15% of the total consumption worldwide in 2020. Therefore, many countries are establishing Green ICT policies which increase energy efficiency due to correspondence climate change. Therefore, governments especially in developing and Islamic countries need to adopt new strategic policies for efficient energy use in ICT. This study presents the current environmental problems related to green ICT and the efforts to solve it. Several studies have warning from the current energy consumption paradigm, based on newly changed ICT practices. This study provides guidelines for decision makers and ICT professionals to enhance their work toward green ICT and eliminating environmental problems. Islamic viewpoint on environment and its protection is considered since it offers comprehensive, stable, and fair viewpoint that is based on main Islamic sources; Quran and Sunnah. Hundreds of Quranic verses and prophet Hadiths clarify (directly or indirectly the right manner in dealing and protection of environment resources. This paper proposes a framework for strategy and policy statements of green ICT based on Islamic perspective to serve the world especially developing and Islamic countries

    2014-06-01

    Full Text Available Business strategy involves adopting the equilibrium between competitiveness and performance, on one hand, and the responsibility towards environmental goals, on the other hand. The transition to green economy becomes synonym with two structural transformations: firstly, the IT industry restructuration through the development of green information and communication technologies (green ICT, and secondly, the using of IT solutions, according to environment protection and sustainable development. The purpose of this paper is to assess the organizational behavior on adopting green information tools into the policies and processes of an enterprise. To conduct this research, a methodology based on an empirical study was used. Proceeding from an investigation that shows the concerns of some Romanian companies in green ICT concept and practices, the findings suggest a low awareness level about these subjects. Practical implications of the study refer to the fact that the results of research may be useful for managers who are looking to implement green ICT practices in their business strategy and the organizational processes.

  20. Green Urban Space Utilization for Mild ICT-Based Touristic Activities: The Case of Pafsilipo Park in Greece

    Directory of Open Access Journals (Sweden)

    Stefanos KARAGIANNIS

    2014-11-01

    Full Text Available This paper discusses the issue of mild touristic activities in green urban landscapes. More specifically, it uses the case of Pasfilipo Park in the city of Karditsa, Greece, where a green urban landscape has been utilized for local life improvement and illustrates existing touristic activities in this area. For the purposes of strengthening landscape’s role, various touristic activities are proposed accompanied by Information and Communications Technologies (ICT. Moreover, this paper queries scientific issues with regard to the capitalization of green urban spaces for small scale touristic and ecological activities, which support local life and local economic growth. This study addresses the above modern requirements for urban development with respect to existing natural and human resources. It attempts to answer the following question: can green open spaces in cities be capitalized for touristic activities that support sustainable growth? In this order, green spaces in cities are recognized as areas for smart growth, where mild touristic activities can be undertaken without ecologic damages and can result in simultaneous economic activities that can lead to local development.

  3. The Appeal and Applicability of ICT Study Materials – The Viewpoint of Generation-Z Pre-Service Teachers

    Directory of Open Access Journals (Sweden)

    Tomaž Bratina

    2017-03-01

    Full Text Available Effective contemporary teaching is closely connected to the inclusion of ICT, which comprises technological tools and the preparation and distribution of multimedia learning content. Therefore, one of the objectives of pre-service teacher education is to produce a technologically competent teacher. For this reason, the study programe includes a range of learning content where pre-service teachers engage in practical work in order to learn about the uses of ICT, tools and procedures for the production and distribution of multimedia learning content. Current generations of pre-service teachers are considered as belonging to Generation Z, or digital natives, and we can consequently expect experience, greater interest in studying the material and motivation to use ICT in their work. After the conclusion of the ICT in Education course, a study was prepared focusing on the learning materials that pre-service teachers find interesting, how they assess the applicability and transferability of this material and on the assessment of their own qualification for preparing multimedia learning materials. The results have shown that contemporary generations are familiar with working with ICT; however, they lack the experience and knowledge for using programs and tools. They want more knowledge and practical work in preparing multimedia learning material and in its distribution. The possibility of distributing multimedia learning content has resulted in a notable interest in working with Moodle, which is evident from the comparison of results from this year’s generation and those from two years ago. Students believe that the syllabus provided is interesting and useful. The acquired knowledge will be useful in the production of future learning materials and for work in other courses. The findings of the study will be used in the updating and preparation of future syllabi.

  6. ICTS AND ENTERPRISE: CONCEPTUAL PROPOSALS TO GENERATE INDICATORS FOR THE INFORMATION SOCIETY

    Directory of Open Access Journals (Sweden)

    Fernando Peirano

    2006-11-01

    Full Text Available This paper is an attempt to deepen the reflection on how Information and Communication Technologies (ICTs diffusion among firms takes place. It adds to author’s previous works on the different strategies adopted by small and medium enterprises (SMEs in Argentina in order to adopt ICTs. The paper is focused in the stylization of the different stages along the evolutive path while incorporating these tools and identifying the factors that influence its dynamics, with special attention to costs. The paper is also an attempt to make progress in the description of the paths or ways through which ICTs can improve firms’ performance. Four alternatives are pointed out, named “Economies through Information”: automation, access to information, learning and innovation processes facilitation and reduction of transaction costs. Authors try to make operable some notions frequently used by other authors interested in these issues and to formulate some hypothesis which still need further elaboration, but which will probably stimulate and inspire the debate around these matters.

  7. Do UOC Students Fit in the Net Generation Profile? An Approach to their Habits in ICT Use

    Directory of Open Access Journals (Sweden)

    Marc Romero,

    2013-07-01

    Full Text Available Some authors have stated that university students born after 1982 have been profoundly influenced by digital technologies, showing different characteristics when compared to previous generations. However, it is worth asking if that is a current observable phenomenon. Are those students born after the 80s really more familiar with ICT tools than those born in previous generations? Do they show different study habits and learning paths? Different research lines (Kennedy, et al., 2010; Bennett, Maton, & Kervin, 2008; Gros, García, & Escofet, 2012 highlight that scientific data is rarely used when discussing this generation’s characteristics; however, none of them have proved in statistical terms that college students do not fit in the Net Generation characteristics and that their habits of ICT use in social and professional activities do not differ from older generations. The international research project, Digital Learners in Higher Education, seeks to develop a sophisticated and evidence-based understanding of university learners in different institutional contexts and the perception of cultures in their use of technology in a social and educational context. Data has been collected from four institutions in Canada and Spain: the British Columbia Institute of Technology, the University of Regina, the Open University of Catalonia (UOC, and the University Rovira i Virgili. In order to develop this project, we used a multi-case study embedded design (Yin, 2009. The UOC’s case is deeply analysed in this paper to affirm that the Net Generation is more speculative than real and that includes students’ perception about this phenomenon, and guidelines are proposed in an eLearning context.

    2011-06-01

    We report the creation of a transgenic dog that conditionally expresses eGFP (enhanced green fluorescent protein) under the regulation of doxycycline. Briefly, fetal fibroblasts infected with a Tet-on eGFP vector were used for somatic cell nuclear transfer. Subsequently reconstructed oocytes were transferred to recipients. Three clones having transgenes were born and one dog was alive. The dog showed all features of inducible expression of eGFP upon doxycycline administration, and successful breeding resulted in eGFP-positive puppies, confirming stable insertion of the transgene into the genome. This inducible dog model will be useful for a variety of medical research studies.

    2012-01-01

    Full Text Available Modern (electric power distribution utilities are faced with high penetration of distributed (electric generation. Renewable generation is of prime interest. Within this generation, the green one incorporating solar (photovoltaic and wind generation is the most important. Consequently, the following two imperatives are established in modern distribution utilities: 1 absorption of as much of available (connected to network green generation as possible and 2 increasing of the limit of green distributed generation penetration. This generation is a significant basis of Smart Distribution Grid Concept. Distributed generation transfers passive distribution network into active one. The active distribution network analysis, control, operation management and planning become significantly complex. This complexity radically hinders the achievement of two above stated imperatives referring to the distributed generation penetration. This paper proves that Distribution Management System is a unique powerful system that integrates all tools necessary for surpassing main difficulties in the achievement of the both imperatives. The proof is obtained by the elaboration of a set of power applications (mathematical calculations integrated in the Distribution Management System. The most important power applications, which deal with voltage / reactive power control, are specially stressed.

    Commercial aviation relies almost entirely on subsonic fixed wing aircraft to constantly move people and goods from one place to another across the globe. While air travel is an effective means of transportation providing an unmatched combination of speed and range, future subsonic aircraft must improve substantially to meet efficiency and environmental targets.The NASA Fundamental Aeronautics Fixed Wing (FW) Project addresses the comprehensive challenge of enabling revolutionary energy efficiency improvements in subsonic transport aircraft combined with dramatic reductions in harmful emissions and perceived noise to facilitate sustained growth of the air transportation system. Advanced technologies and the development of unconventional aircraft systems offer the potential to achieve these improvements. Multidisciplinary advances are required in aerodynamic efficiency to reduce drag, structural efficiency to reduce aircraft empty weight, and propulsive and thermal efficiency to reduce thrust-specific energy consumption (TSEC) for overall system benefit. Additionally, advances are required to reduce perceived noise without adversely affecting drag, weight, or TSEC, and to reduce harmful emissions without adversely affecting energy efficiency or noise.The paper will highlight the Fixed Wing project vision of revolutionary systems and technologies needed to achieve these challenging goals. Specifically, the primary focus of the FW Project is on the N+3 generation; that is, vehicles that are three generations beyond the current state of the art, requiring mature technology solutions in the 2025-30 timeframe

    2015-06-01

    Full Text Available Much has been said and written over the years regarding green chemistry concept and use of green solvents. The green solvents can potentially replace the traditional or classical solvents in order to reduce the environment footprint or their harmful impact on human being and/or environment. Vapour-liquid equilibrium data is indispensable for the design of distillation columns for separation processes which account for a large percentage of total costs in a typical chemical plant. Though extensive approach has been made for the replacement of traditional solvents, but not enough consideration been given for vapour-liquid equilibrium data, required for designing separation processes in case of replacement with green solvents. So this paper aims at encouraging vapour-liquid equilibrium data generation for design of efficient separation for binary systems involving ethereal green solvents such as cyclopentyl methyl ether (CPME and 2-methyl tetrahydrofuran (2-MeTHF. A brief review and outline of procedure for generating vapour-liquid equilibrium data is presented here.

    Full Text Available Open Universities across the world are embracing ICT based teaching and learning process to disseminate quality education to their learners spread across the globe. In India availability and access of ICT and learner characteristics are uneven and vary from state to state. Hence it is important to establish the facts about ICT access among learners, their ICT usage patterns and their readiness to use ICT for educational purpose. In view of this, a study was conducted with the objective to find out the access level of ICT among distance learners. The analysis indicates that maximum learners have desktop/laptops and most of them are accessing internet very frequently from their home. The analysis also indicates that maximum respondents are browsing social networking sites followed by educational and e-mail service providing websites. Findings suggest that there is a need to generate ICT based tutorials complemented with social networking tools and mobile applications. Study also shows that learners are equipped with mobile phones and they are browsing internet through it and also availing support services offered by the university. Hence possibility of integrating mobile phone services may be used for providing learner support services and content delivery.

    2016-01-01

    We report on efficient nonlinear generation of ultrafast, higher order "perfect" vortices at the green wavelength. Based on Fourier transformation of the higher order Bessel-Gauss beam generated through the combination of spiral phase plate and axicon we have transformed the Gaussian beam of the ultrafast Yb-fiber laser at 1060 nm into perfect vortices of power 4.4 W and order up to 6. Using single-pass second harmonic generation (SHG) of such vortices in 5-mm long chirped MgO-doped, periodically poled congruent LiNbO$_3$ crystal we have generated perfect vortices at green wavelength with output power of 1.2 W and vortex order up to 12 at single-pass conversion efficiency of 27% independent of its order. This is the highest single-pass SHG efficiency of any optical beams other than Gaussian beams. Unlike the disintegration of higher order vortices in birefringent crystals, here, the use of quasi-phase matching process enables generation of high quality vortices even at higher orders. The green perfect vortice...

    2014-12-01

    Spectrally broad frequency comb generation over 510–555 nm range was reported on chirped quasi-phase-matching (QPM) χ{sup (2)} nonlinear photonic crystals of 12 mm length with periodicity stepwise increased from 5.9 μm to 7.1 μm. When pumped with nanosecond infrared (IR) frequency comb derived from a QPM optical parametric oscillator (OPO) and spanned over 1040 nm to 1090 nm wavelength range, the 520 nm to 545 nm up-converted green spectra were shown to consist of contributions from (a) second-harmonic generation among the signal or the idler modes, and (b) sum-frequency generation (SFG) from the neighboring pairs of the signal or the idler modes. These mechanisms led the up-converted green frequency comb to have the same mode spacing of 450 GHz as that in the IR-OPO pump comb. As the pump was further detuned from the aforementioned near-degeneracy point and moved toward the signal (1020–1040 nm) and the idler (1090–1110 nm) spectral range, the above QPM parametric processes were preserved in the chirped QPM devices to support up-converted green generation in the 510–520 nm and the 545–555 nm spectral regime. Additional 530–535 nm green spectral generation was also observed due to concurrence of multi-wavelength SFG processes between the (signal, idler) mode pairs. These mechanisms facilitate the chirped QPM device to support a single-pass up-conversion efficiency ∼10% when subject to an IR-OPO pump comb with 200 mW average power operated near- or off- the degeneracy point.

    Bioelectricity production from blue-green algae was examined in a single chamber tubular microbial fuel cell (MFC). The blue-green algae powered MFC produced a maximum power density of 11 4 mW/m(2) at a current density of 0.55 mA/m(2). Coupled with the bioenergy generation, high removal efficiencies of chemical oxygen demand (COD) and nitrogen were also achieved in MFCs. Over 78.9% of total chemical oxygen demand (TCOD), 80.0% of soluble chemical oxygen demand (SCOD), 91.0% of total nitrogen (total-N) and 96.8% ammonium-nitrogen (NH(3)-N) were removed under closed circuit conditions in 12 days, which were much more effective than those under open circuit and anaerobic reactor conditions. Most importantly, the MFC showed great ability to remove microcystins released from blue-green algae. Over 90.7% of MC-RR and 91.1% of MC-LR were removed under closed circuit conditions (500Ω). This study showed that the MFC could provide a potential means for electricity production from blue-green algae coupling algae toxins removal.

    Significant amounts of energy are consumed by the building sector and sustainable solutions need to be implemented. A new approach, the solar tri-generation system, with photovoltaic system and thermo-electric modules, has been developed to provide buildings with electricity, solar heating and cooling, and hot water. This paper presents the application of this system to increase the utilization rate of solar energy with simple solar daylight tubes. The example of the ESER green office building, which uses the solar tri-generation system and is a net zero exergy building, is presented herein. It was shown that solar tri-generation is an advantageous solution but that its performance depends on local meteorological conditions. This paper demonstrated that the utilization of solar tri-generation, if optimized in line with local conditions and design constraints, is a good solution for developing sustainable buildings.

    We report on the design, fabrication and performance of high-power and high-modulation-speed 1060-nm DBR lasers for green-light emission by second harmonic generation. Single-spatial-mode and single-wavelength power more than 450 mW of 1060-nm wavelength was achieved with a 3-section DBR laser with non-absorbing DBR and phase sections created by an impurity-free quantum-well intermixing technique. A thermally-induced wavelength tuning of 2.4 nm and a carrier-induced wavelength tuning of -0.85 nm were obtained by injecting current into the DBR section. The green power as high as 104.6 mW was demonstrated by coupling the DBR laser output to a second-harmonic-generation waveguide. Measured rise/fall times of 0.2 ns for direct intensity modulation and 0.6 ns for wavelength modulation make the DBR lasers suitable for >=50-MHz green-light-modulation applications. The detrimental thermally-induced patterning effect and a differential-phase modulation scheme as a solution are discussed.

    Thermoelectric materials embedded through or inside exterior glass windows can act as a viable source of supplemental power in geographic locations where hot weather dominates. This thermoelectricity is generated because of the thermal difference between the high temperature outside and the relatively cold temperature inside. Using physical vapor deposition process, we experimentally verify this concept by embedding bismuth telluride and antimony telluride through the 5 mm Plexiglas to demonstrate 10 nW of thermopower generation with a temperature gradient of 21 °C. Albeit tiny at this point with non-optimized design and development, this concept can be extended for relatively large-scale power generation as an additional power supply for green building technology.

    2016-04-18

    A major limitation in using membrane-based separation processes is the loss of performance due to membrane fouling. This drawback can be addressed thanks to surface modification treatments. A new and promising surface modification using green chemistry has been recently investigated. This modification is carried out at room temperature and in aqueous medium using green catalyst (enzyme) and nontoxic modifier, which can be safely labelled "green surface modification". This modification can be considered as a nucleus of new generation of antifouling membranes and surfaces. In the current research, ferulic acid modifier and laccase bio-catalyst were used to make poly(ethersulfone) (PES) membrane less vulnerable to protein adsorption. The blank and modified PES membranes are evaluated based on e.g., their flux and protein repellence. Both the blank and the modified PES membranes (or laminated PES on silicon dioxide surface) are characterized using many techniques e.g., SEM, EDX, XPS and SPM, etc. The pure water flux of the most modified membranes was reduced by 10% on average relative to the blank membrane, and around a 94% reduction in protein adsorption was determined. In the conclusions section, a comparison between three modifiers-ferulic acid, and two other previously used modifiers (4-hydroxybenzoic acid and gallic acid)-is presented.

  17. Revised Estimates of Hikurangi Slow Slip Using FEM-Generated Green's Functions

    Science.gov (United States)

    Williams, C. A.; Wallace, L. M.

    2013-12-01

    Slow slip events (SSEs) occur along nearly the entire Hikurangi subduction margin adjacent to the North Island, New Zealand. The occurrence of both shallow and deep SSEs and the change in locking behavior observed along the Hikurangi Margin provide a unique opportunity to examine the factors controlling both seismic and aseismic behavior. It is therefore critical that our slip estimates are as accurate as possible. Existing SSE slip estimates use geodetic data in conjunction with an elastic half-space dislocation model to infer the slip distributions for these events. Two recent developments provide the potential to obtain more accurate estimates for these events, however. First, a New Zealand-wide seismic velocity model (Eberhart-Phillips et al., 2010) allows us to accurately represent the effects of complex variations in elastic properties. Second, a revised interface geometry has just been developed (Williams et al., 2013), allowing us to represent more accurately the interface on which the events are assumed to occur. We use the finite element code PyLith to generate Green's functions for the entire Hikurangi interface, and we then use these in place of the elastic half-space Green's functions used previously. We do our work in two stages. In the first stage, we replace the existing geometry for the Hikurangi interface with the new geometry, thus allowing us to isolate the changes due purely to the revised geometry. In the second phase, we use the FEM-generated Green's functions in the DEFNODE inversion program, which allows us to isolate the changes that are due to changes in the assumed elastic properties. In this initial work, we apply the method to two Hikurangi SSEs: one deep event and one shallow one. The differences observed for these two events will allow us to evaluate the relative importance of interface geometry and assumed elastic structure for future SSE slip inversions.

  18. Next-Generation Environment-Aware Cellular Networks: Modern Green Techniques and Implementation Challenges

    KAUST Repository

    Ghazzai, Hakim

    2016-09-16

    Over the last decade, mobile communications have been witnessing a noteworthy increase of data traffic demand that is causing an enormous energy consumption in cellular networks. The reduction of their fossil fuel consumption in addition to the huge energy bills paid by mobile operators is considered as the most important challenges for the next-generation cellular networks. Although most of the proposed studies were focusing on individual physical layer power optimizations, there is a growing necessity to meet the green objective of fifth-generation cellular networks while respecting the user\\'s quality of service. This paper investigates four important techniques that could be exploited separately or together in order to enable wireless operators achieve significant economic benefits and environmental savings: 1) the base station sleeping strategy; 2) the optimized energy procurement from the smart grid; 3) the base station energy sharing; and 4) the green networking collaboration between competitive mobile operators. The presented simulation results measure the gain that could be obtained using these techniques compared with that of traditional scenarios. Finally, this paper discusses the issues and challenges related to the implementations of these techniques in real environments. © 2016 IEEE.

    Recent studies in quantum biology suggest that quantum mechanics help us to explore quantum processes in biological system. Here, we demonstrate generation of photon pairs through spontaneous four-wave mixing process in naturally occurring fluorescent proteins. We develop a general empirical method for analyzing the relative strength of nonlinear optical interaction processes in five different organic fluorophores. Our results indicate that the generation of photon pairs in green fluorescent proteins is subject to less background noises than in other fluorophores, leading to a coincidence-to-accidental ratio ~145. As such proteins can be genetically engineered and fused to many biological cells, our experiment enables a new platform for quantum information processing in a biological environment such as biomimetic quantum networks and quantum sensors.

    2005-01-01

    Full Text Available The change towards the information society implies that many countries have to change their curricula, because students need to develop competencies that are not addressed in the traditional curricula. A case study approach was applied to examine curriculum changes in ICT-supported pedagogical practices from 28 countries. The analysis focused on curriculum content and goals of the ICT-supported pedagogical practices, how these aims were implemented in practice and which outcomes for students and teachers could be observed. The results showed that the curriculum content often was not new but rather was delivered in a different way. Many ICT-supported pedagogical practices strove to realize new goals important for lifelong learning in an information society. Content and goals were offered in curricular settings, often crossing the traditional boundaries of academic subjects. In many of the cases students worked on topics that were meaningful to them.

  8. Polymorphism of Mhc-DRB alleles in Cercopithecus aethiops (green monkey): generation and functionality.

    1998-05-01

    DRB genes have been studied for the first time in green monkeys (Cercopithecus aethiops). Eleven new DRB alleles (exon 2, exon 3) have been obtained and sequenced from cDNA. A limited number of lineages have been identified: DRB1*03 (4 alleles), DRB1*07 (3 alleles), DRB5 (1 allele), DRB*w6 (1 allele), and DRB*w7 (2 alleles). The existence of Ceae-DRB1 duplications is supported by the finding of 3 DRB1 alleles in 3 different individuals. Ceae-DRB1*0701 may be non-functional because it bears serine at position 82, which hinders molecule surface expression in mice; the allele is only found in Ceae-DRB duplicated haplotypes. Base changes in cDNA Ceae-DRB alleles are consistent with the generation of polymorphism by point mutations or short segment exchanges between alleles. The eleven green monkey DRB alleles meet the requirements for functionality as antigen-presenting molecules (perhaps, excluding DRB1*0701), since: 1) they have been isolated from cDNA and do not present deletions, insertions or stop codons: 2) structural motifs necessary for a correct folding of the molecule, for the formation of DR/DR dimers and for CD4 interactions are conserved, and 3) the number of non-synonymous substitutions is higher than the number of synonymous substitutions in the peptide binding region (PBR), while the contrary holds true for the non-PBR region.

    2014-07-01

    NREL conducted eight model projects for Millennium Challenge Corporation's (MCC) Compact with Indonesia. Green Prosperity, the largest project of the Compact, seeks to address critical constraints to economic growth while supporting the Government of Indonesia's commitment to a more sustainable, less carbon-intensive future. This study evaluates electricity generation from the organic content of wastewater at a palm oil mill in Muaro Jambi, Sumatra. Palm mills use vast amounts of water in the production process resulting in problematic waste water called palm oil mill effluent (POME). The POME releases methane to the atmosphere in open ponds which could be covered to capture the methane to produce renewable electricity for rural villages. The study uses average Indonesia data to determine the economic viability of methane capture at a palm oil mill and also evaluates technology as well as social and environmental impacts of the project.

    2012-03-01

    Full Text Available Near-infrared (NIR fluorophores are the focus of extensive research for combined molecular imaging and hyperthermia. In this study, we showed that the cyanine dye IR820 has optical and thermal generation properties similar to those of indocyanine green (ICG but with improved in vitro and in vivo stability. The fluorescent emission of IR820 has a lower quantum yield than ICG but less dependence of the emission peak location on concentration. IR820 demonstrated degradation half-times approximately double those of ICG under all temperature and light conditions in aqueous solution. In hyperthermia applications, IR820 generated lower peak temperatures than ICG (4–9% after 3-minute laser exposure. However, there was no significant difference in hyperthermia cytotoxicity, with both dyes causing significant cell growth inhibition at concentrations ≥ 5 μM. Fluorescent images of cells with 10 μM IR820 were similar to ICG images. In rats, IR820 resulted in a significantly more intense fluorescence signal and significantly higher organ dye content than for ICG 24 hours after intravenous dye administration (p < .05. Our study shows that IR820 is a feasible agent in experimental models of imaging and hyperthermia and could be an alternative to ICG when greater stability, longer image collection times, or more predictable peak locations are desirable.

    Full Text Available Intervention programs aimed at promoting study and work opportunities in the Information and Communications Technology (ICT field to schoolgirls have been encouraged to combat a decline in the interest among girls to study ICT at school. The goal of our study is to investigate the influence of such interventions on schoolgirls’ intentions to choose a career in the ICT field by analysing comprehensive survey data (n = 3577, collected during four interventions in Australia, using the Partial Least Squares method. Our study is also aimed at identifying other factors influencing ICT career intentions. We found that the attitude towards interventions has an indirect influence on ICT career intentions by affecting interest in ICT. Our results also challenge several existing theoretical studies by showing that factors that had previously been suggested as influencers were found to have little or no impact in this study, these being same-sex education and computer usage.

    2012-11-01

    The pervasive use of information and communication technology (ICT) in modern societies enables countless opportunities for individuals, institutions, businesses and scientists, but also raises difficult ethical and social problems. In particular, ICT helped to make societies more complex and thus harder to understand, which impedes social and political interventions to avoid harm and to increase the common good. To overcome this obstacle, the large-scale EU flagship proposal FuturICT intends to create a platform for accessing global human knowledge as a public good and instruments to increase our understanding of the information society by making use of ICT-based research. In this contribution, we outline the ethical justification for such an endeavor. We argue that the ethical issues raised by FuturICT research projects overlap substantially with many of the known ethical problems emerging from ICT use in general. By referring to the notion of Value Sensitive Design, we show for the example of privacy how this core value of responsible ICT can be protected in pursuing research in the framework of FuturICT. In addition, we discuss further ethical issues and outline the institutional design of FuturICT allowing to address them.

    Jeffery, Keith; Harrison, Matt; Bailo, Daniele

    2016-04-01

    The EPOS-PP Project 2010-2014 proposed an architecture and demonstrated feasibility with a prototype. Requirements based on use cases were collected and an inventory of assets (e.g. datasets, software, users, computing resources, equipment/detectors, laboratory services) (RIDE) was developed. The architecture evolved through three stages of refinement with much consultation both with the EPOS community representing EPOS users and participants in geoscience and with the overall ICT community especially those working on research such as the RDA (Research Data Alliance) community. The architecture consists of a central ICS (Integrated Core Services) consisting of a portal and catalog, the latter providing to end-users a 'map' of all EPOS resources (datasets, software, users, computing, equipment/detectors etc.). ICS is extended to ICS-d (distributed ICS) for certain services (such as visualisation software services or Cloud computing resources) and CES (Computational Earth Science) for specific simulation or analytical processing. ICS also communicates with TCS (Thematic Core Services) which represent European-wide portals to national and local assets, resources and services in the various specific domains (e.g. seismology, volcanology, geodesy) of EPOS. The EPOS-IP project 2015-2019 started October 2015. Two work-packages cover the ICT aspects; WP6 involves interaction with the TCS while WP7 concentrates on ICS including interoperation with ICS-d and CES offerings: in short the ICT architecture. Based on the experience and results of EPOS-PP the ICT team held a pre-meeting in July 2015 and set out a project plan. The first major activity involved requirements (re-)collection with use cases and also updating the inventory of assets held by the various TCS in EPOS. The RIDE database of assets is currently being converted to CERIF (Common European Research Information Format - an EU Recommendation to Member States) to provide the basis for the EPOS-IP ICS Catalog.

    2017-03-01

    We present novel methods implemented within the non-equilibrium Green function code (NEGF) TRANSIESTA based on density functional theory (DFT). Our flexible, next-generation DFT-NEGF code handles devices with one or multiple electrodes (Ne ≥ 1) with individual chemical potentials and electronic temperatures. We describe its novel methods for electrostatic gating, contour optimizations, and assertion of charge conservation, as well as the newly implemented algorithms for optimized and scalable matrix inversion, performance-critical pivoting, and hybrid parallelization. Additionally, a generic NEGF ;post-processing; code (TBTRANS/PHTRANS) for electron and phonon transport is presented with several novelties such as Hamiltonian interpolations, Ne ≥ 1 electrode capability, bond-currents, generalized interface for user-defined tight-binding transport, transmission projection using eigenstates of a projected Hamiltonian, and fast inversion algorithms for large-scale simulations easily exceeding 106 atoms on workstation computers. The new features of both codes are demonstrated and bench-marked for relevant test systems.

    2016-05-26

    Green fluorescent protein (GFP)-like pigments have been proposed to have beneficial effects on coral photobiology. Here, we investigated the relationships between green fluorescence, coral heating and tissue optics for the massive coral Dipsastraea sp. (previously Favia sp.). We used microsensors to measure tissue scalar irradiance and temperature along with hyperspectral imaging and combined imaging of variable chlorophyll fluorescence and green fluorescence. Green fluorescence correlated positively with coral heating and scalar irradiance enhancement at the tissue surface. Coral tissue heating saturated for maximal levels of green fluorescence. The action spectrum of coral surface heating revealed that heating was highest under red (peaking at 680 nm) irradiance. Scalar irradiance enhancement in coral tissue was highest when illuminated with blue light, but up to 62% (for the case of highest green fluorescence) of this photon enhancement was due to green fluorescence emission. We suggest that GFP-like pigments scatter the incident radiation, which enhances light absorption and heating of the coral. However, heating saturates, because intense light scattering reduces the vertical penetration depth through the tissue eventually leading to reduced light absorption at high fluorescent pigment density. We conclude that fluorescent pigments can have a central role in modulating coral light absorption and heating.

    ICT can go from being a part of the climate challenge to be an important part of the solution by simplify, rationalize and replace a variety of features and services. ICT's contribute through production and operation for approx. 2.5 % of global greenhouse gas emissions. At the same time estimates show that ICT could help to reduce total greenhouse gas emissions by up to 15 % by 2020 through a series of measures. ICT can, for example. contribute to reduce travel activity through remote collaboration, the transition from material to virtual products and by greater energy efficiency in buildings and vehicles. Through remote collaboration, green tender rounds and change of focus from products to services, can authorities reduce their own emissions. In addition, the authorities go ahead as good examples by illustrating how environment benefits from governmental ICT investments. If we assume that video conferencing can replace 1 of 5 flights among the 140 000 state employees, this can lead to a reducted emission of 14 600 tonnes of CO{sub 2} per year. (AG)

    Highlights: • We analyse ICT equipment reuse operations of socio-economic enterprises. • Most common ICT products dealt with are computers and related equipment. • In the UK in 2010, ∼143,750 appliances were reused. • Marketing and legislative difficulties are the common hurdles to reuse activities. • Socio-economic enterprises can significantly contribute to resource efficiency. - Abstract: In Europe, socio-economic enterprises such as charities, voluntary organisations and not-for-profit companies are involved in the repair, refurbishment and reuse of various products. This paper characterises and analyses the operations of socio-economic enterprises that are involved in the reuse of Information and Communication Technology (ICT) equipment. Using findings from a survey, the paper specifically analyses the reuse activities of socio-economic enterprises in the UK from which Europe-wide conclusions are drawn. The amount of ICT products handled by the reuse organisations is quantified and potential barriers and opportunities to their operations are analysed. By-products from reuse activities are discussed and recommendations to improve reuse activities are provided. The most common ICT products dealt with by socio-economic enterprises are computers and related equipment. In the UK in 2010, an estimated 143,750 appliances were reused. However, due to limitations in data, it is difficult to compare this number to the amount of new appliances that entered the UK market or the amount of waste electrical and electronic equipment generated in the same period. Difficulties in marketing products and numerous legislative requirements are the most common barriers to reuse operations. Despite various constraints, it is clear that organisations involved in reuse of ICT could contribute significantly to resource efficiency and a circular economy. It is suggested that clustering of their operations into “reuse parks” would enhance both their profile and their

    The Singapore Ministry of Education conducted a smallscale pilot study in Y2003 to find out how engaged learning was interpreted and translated into practice by teachers and the role of ICT in facilitating engaged learning. For this study, 6 teachers were involved, of which 2 were English language teachers. A case study methodology incorporating an intervention element was adopted. The analysis of the collected data, in the form of pre-lesson interview, lesson observations/videotaping and post-lesson interviews, surfaced teachers'understanding and implementation of engaged learning in the classroom context. This paper focuses on the 2 case studies in which one primary and secondary English language teachers were observed for the way they designed and implemented ICT-based English lessons to promote engaged learning. Although the insights generated by the 2 case studies are legitimate in their own instances, they may be used to sensitize those involved in professional development to five interdependent factors that influence the way ICT may be used to promote engaged learning in the EL classroom.

    2008-04-09

    We present the synthesis, properties, and biological applications of Peroxy Lucifer 1 (PL1), a new fluorescent probe for imaging hydrogen peroxide produced in living cells by a ratiometric response. PL1 utilizes a chemoselective boronate-based switch to detect hydrogen peroxide by modulation of internal charge transfer (ICT) within a 1,8-naphthalimide dye. PL1 features high selectivity for hydrogen peroxide over similar reactive oxygen species, including superoxide, and nitric oxide, and a 65 nm shift in emission from blue-colored fluorescence to green-colored fluorescence upon reaction with peroxide. Two-photon confocal microscopy experiments in live macrophages show that PL1 can ratiometrically visualize localized hydrogen peroxide bursts generated in living cells at immune response levels.

    Colombo, Fausto; Aroldi, Piermarco; Carlo, Simone

    2014-01-01

    Ageing in western society has become a key issue in political and academic debate: politicians, sociologists, doctors, demographers, psychologists, economists are trying to understand how ageing will impact our future society. In this frame, media and communication technologies seem to be more and more relevant for the elderly, thanks to those services and devices helping people to grow old actively. Technologies, the Internet and ICTs could help the elderly to improve their quality of life, to be healthy and independent and to get better assistance. Our ongoing research investigates the relationship between the elderly and use of technologies, and explores the role played by media and ICTs in building a friendly and positive environment for the elderly, and in constructing and maintaining social relations and promoting healthy ageing. Specifically, the research will investigate the use of ICTs by the elderly by taking into account two different perspectives: a) Exchanges between generations: lengthening of life corresponds to a longer period of cohabitation between at least three generations (grandparents, children, grandchildren), and also of co-use of digital media. The research wants to investigate relations between two age groups (grandparents and grandchildren; young people and older people) to understand the dynamics of intergenerational mutuality in the use of technologies and ICTs. b) Media, ICTs, Health: the Western world is increasingly populated by elderly population. Technologies and ICTs can help elderly people to improve their quality of life, to be healthy and independent and to get better assistance. ICTs should encourage active ageing and, in the case of health technologies, new models of care. The project, lasting 1 year, is based on (1) a survey on young elderly (65-74 yrs) population in Italy, and (2) a field-work which consists of family interviews and ethnographical sections in natural contexts.

    The operating voltage of the tandem green phosphorescent organic light-emitting device with a 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile layer was improved by 3% over that of the organic light-emitting device with a molybdenum trioxide layer. The maximum brightness of the tandem green phosphorescent organic light-emitting device at 21.9 V was 26,540 cd/m{sup 2}. The dominant peak of the electroluminescence spectra for the devices was related to the fac-tris(2-phenylpyridine) iridium emission. - Highlights: • Tandem OLEDs with CGL were fabricated to enhance their efficiency. • The operating voltage of the tandem OLED with a HAT-CN layer was improved by 3%. • The efficiency and brightness of the tandem OLED were 13.9 cd/A and 26,540 cd/m{sup 2}. • Efficiency of the OLED with a HAT-CN layer was lower than that with a MoO{sub 3} layer. - Abstract: Tandem green phosphorescent organic light-emitting devices with a 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile or a molybdenum trioxide charge generation layer were fabricated to enhance their efficiency. Current density–voltage curves showed that the operating voltage of the tandem green phosphorescent organic light-emitting device with a 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile layer was improved by 3% over that of the corresponding organic light-emitting device with a molybdenum trioxide layer. The efficiency and the brightness of the tandem green phosphorescent organic light-emitting device were 13.9 cd/A and 26,540 cd/m{sup 2}, respectively. The current efficiency of the tandem green phosphorescent organic light-emitting device with a 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile layer was lower by 1.1 times compared to that of the corresponding organic light-emitting device with molybdenum trioxide layer due to the decreased charge generation and transport in the 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile layer resulting from triplet–triplet exciton annihilation.

This article completes this perspective indicating that the incorporation of technology transforms the instrument in mediator for the transformations of the mental operations performed by the mind, thus acting on the plastic structure of the brain. This occurs in the use of the instrument of language, in that of literacy and it takes place again with the incorporation of ICT, given that it is a technology of work in culture. ICT are, at the same time, model and instrument for observation and investigation of brain activity.

  20. Cumulative Effect of Pressing and Drying on Stress Generation within a Green Ceramic Compact

    Directory of Open Access Journals (Sweden)

    E. Vidal-Sallé

    2014-01-01

    Full Text Available The internal stress field induced by uniaxial pressing and subsequent convective drying of a green ceramic powder was simulated by the finite element method. A density dependent elastoplastic constitutive law was used for the mechanical modeling of the compaction. A diffusive water transfer equation and a purely elastic behavior with imposed hydrostrain involving shrinkage were applied for the modeling of the drying process. The key material properties (hydrodiffusivity, hydrocontraction coefficient, Young’s modulus, Poisson’s ratio, and yield surface parameters had been experimentally measured and introduced as functions of material density and water content. If residual stresses due to the compaction operation were taken into account, the maximum value of the tensile stress at the top external edge of the wheel and at the beginning of the drying process was two times higher than for a stress free green ceramic compact. Beyond the residual stress onset, the compaction operation induced density heterogeneities which had important consequences on the mechanical behavior of the compact.

    2003-03-26

    In Japan, tea is generally sold blended, though 90% of the total production is clonal. Due to the increasingly strict consumer need and taste, however, more and more Japanese green teas are being sold under their particular cultivar name. Moreover, tea made from Yabukita, a much appreciated cultivar originally developed in Japan, has recently been produced and imported from a neighboring country. This paper describes a simple and inexpensive methodology capable of identifying fresh and processed Japanese green teas to discourage its fraudulent commercialization. The study was based on 46 main tea cultivars, and polymorphism detected through STS-RFLP analysis of the coding and noncoding DNA regions of three genes, namely phenylalanine ammonia-lyase, chalcone synthase, and dihydroflavonol 4-reductase, for which nucleotide information was available. All 46 tea cultivars analyzed could be easily distinguished using a combination of codominant DNA markers. Yabukita displayed a unique profile when PAL intron was digested with DdeI, thus allowing its rapid authentication at low cost.

  8. Analysis of Carbon Policies for Electricity Networks with High Penetration of Green Generation

    Science.gov (United States)

    Feijoo, Felipe A.

    In recent decades, climate change has become one of the most crucial challenges for humanity. Climate change has a direct correlation with global warming, caused mainly by the green house gas emissions (GHG). The Environmental Protection Agency in the U.S. (EPA) attributes carbon dioxide to account for approximately 82% of the GHG emissions. Unfortunately, the energy sector is the main producer of carbon dioxide, with China and the U.S. as the highest emitters. Therefore, there is a strong (positive) correlation between energy production, global warming, and climate change. Stringent carbon emissions reduction targets have been established in order to reduce the impacts of GHG. Achieving these emissions reduction goals will require implementation of policies like as cap-and-trade and carbon taxes, together with transformation of the electricity grid into a smarter system with high green energy penetration. However, the consideration of policies solely in view of carbon emissions reduction may adversely impact other market outcomes such as electricity prices and consumption. In this dissertation, a two-layer mathematical-statistical framework is presented, that serves to develop carbon policies to reduce emissions level while minimizing the negative impacts on other market outcomes. The bottom layer of the two layer model comprises a bi-level optimization problem. The top layer comprises a statistical model and a Pareto analysis. Two related but different problems are studied under this methodology. The first problem looks into the design of cap-and-trade policies for deregulated electricity markets that satisfy the interest of different market constituents. Via the second problem, it is demonstrated how the framework can be used to obtain levels of carbon emissions reduction while minimizing the negative impact on electricity demand and maximizing green penetration from microgrids. In the aforementioned studies, forecasts for electricity prices and production cost

    2008-09-01

    Color characteristics of an RGBW (red, green, blue, white) electrophoretic display (EPD) prototype developed by Samsung Electronics are analyzed. EPD shows strong crosstalk between subpixels because of both the fringe field between subpixels and the scattering phenomena at the display surface. An RGB-to-RGBW color-decomposition algorithm optimized to EPD characteristics is developed that compensates for color deterioration due to the fringe field and scattering phenomena. For the four-color-decomposition algorithm, white is added to the primary colors to enhance the reflectance of the vivid colors while minimizing chroma loss. The psychophysical experimental result shows that images rendered with the algorithms developed in this study are preferred more than 90% of the time over those rendered with algorithms from previous studies. This research proves that, in spite of the limited physical property of EPD, the color quality can be improved dramatically through the use of well-designed color-rendering algorithms.

    The issue of testing and labelling building materials and products and the criteria that should be used to describe their performance characteristics were discussed. The Green Building Challenge Project was established to develop a method for assessing building performance with an emphasis on energy and environmental performance. International and collaborative processes will be used to develop the method of assessment. The performance of more than 30 comparable buildings from the participating countries will be assessed in 1998 and results of the process will be reported at an international conference scheduled for Vancouver during October 1998. Equal focus will be placed on the performance of the buildings and the adequacy of the assessment framework. The assessment will focus on the following design features: land use, water use, materials, air borne emissions during building production and building operation, solid waste from building operations, liquid waste flows to municipal system, indoor air quality, thermal comfort, noise and acoustics, and longevity. 5 refs., 2 tabs.

    Precise diagnostics of picocoulomb level particle bunches produced by laser plasma accelerators (LPAs) can be a significant challenge. Without proper care, the small signals associated with such bunches can be dominated by a background generated by laser, target, laser-plasma interaction and particle induced radiation. In this paper, we report on first charge measurements using the newly developed Turbo-ICT for LPAs. We outline the Turbo-ICT working principle, which allows precise sub-picocoulomb measurements even in the presence of significant background signals. A comparison of the Turbo-ICT, a conventional integrating current transformer (ICT) and a scintillating screen (Lanex) was carried out at the Berkeley Lab Laser Accelerator. Results show that the Turbo-ICT can measure sub-picocoulomb charge accurately and has significantly improved noise immunity compared to the ICT.

    The difficulty of EUV lithography system development has prolonged the industry's dependence on ArF excimer lasers to realize further advancements in lithography process technologies. Smaller CD with reduced cost requires tighter specifications, and the potential extension to 450mm wafers introduces extremely difficult performance challenges on lasers. One of the most important features of the next generation lasers will be the ability to support green operations while further improving cost of ownership and performance. For example, electricity consumption costs and the dependence on rare gases, such as neon and helium, will become critical considerations for HVM process going forward. As a laser vendor, Gigaphoton continues to innovate and develop solutions that address these important issues. The latest model GT64A with its field-proven, twin-chamber platform has reduced environmental impact while upgrading performance and power. A variety of green technologies are employed on the GT64A. The first is the reduction of gas usage. Parameters, such as input power and gas pressure are closely monitored during operations and fed back to the injection/exhaust gas controller system. By applying a special algorithm, the laser gas consumption can be reduced by up to 50%. More than 96% of the gas used by the lasers is neon. Another rare gas that requires attention is Helium. Recently the unstable supply of helium became a serious worldwide issue. To cope with this situation, Gigaphoton is developing lasers that support completely helium-free operations.

    Green cut material is a potential source of renewable energy which is not fully exploited through conventional energy recovery systems. A new energy conversion process, the integrated generation of solid fuel and biogas from biomass (IFBB), which includes mechanical separation after hydro-thermal conditioning, was investigated. Ash softening temperature and lower heating value of the solid fuel were increased through the IFFB process in comparison to the untreated raw material. The net energy yield of IFBB at 40 °C conditioning temperature ranged between 1.96 and 2.85 kWh kg(-1) dry matter (DM) and for the direct combustion between 1.75 and 2.65 kWh kg(-1) DM. Conversion efficiencies for the IFBB system were 0.42-0.68 and for direct combustion 0.42-0.63. The IFBB system produces storable energy from material which is nowadays not used for energy conversion.

  9. ICT reuse in socio-economic enterprises.

    2013-12-01

    In Europe, socio-economic enterprises such as charities, voluntary organisations and not-for-profit companies are involved in the repair, refurbishment and reuse of various products. This paper characterises and analyses the operations of socio-economic enterprises that are involved in the reuse of Information and Communication Technology (ICT) equipment. Using findings from a survey, the paper specifically analyses the reuse activities of socio-economic enterprises in the U.K. from which Europe-wide conclusions are drawn. The amount of ICT products handled by the reuse organisations is quantified and potential barriers and opportunities to their operations are analysed. By-products from reuse activities are discussed and recommendations to improve reuse activities are provided. The most common ICT products dealt with by socio-economic enterprises are computers and related equipment. In the U.K. in 2010, an estimated 143,750 appliances were reused. However, due to limitations in data, it is difficult to compare this number to the amount of new appliances that entered the U.K. market or the amount of waste electrical and electronic equipment generated in the same period. Difficulties in marketing products and numerous legislative requirements are the most common barriers to reuse operations. Despite various constraints, it is clear that organisations involved in reuse of ICT could contribute significantly to resource efficiency and a circular economy. It is suggested that clustering of their operations into "reuse parks" would enhance both their profile and their products. Reuse parks would also improve consumer confidence in and subsequently sales of the products. Further, it is advocated that industrial networking opportunities for the exchange of by-products resulting from the organisations' activities should be investigated. The findings make two significant contributions to the current literature. One, they provide a detailed insight into the reuse operations

    2011-12-01

    Full Text Available Abstract Background Reporter genes are often used as a selectable marker for generation of recombinant viruses in order to investigate the mechanism of pathogenesis and to obtain candidate vaccine viruses. Routine selection of the recombinant parapoxvirus is time-consuming and labor intensive. Therefore, developing a novel method for selection is critical. Results In this study, we developed a rapid method to generate recombinant Orf viruses (ORFV based on the enhanced green fluorescent protein (EGFP reporter gene as a selectable marker. The coding sequence of EGFP gene was amplified from pEGFP-N1 vector and subcloned into the pZIPPY-neo/gus plasmid under the control of the early-late vaccinia virus (VACV VV7.5 promoter and flanked by two multiple cloning sites (MCS to generate a novel transfer vector pSPV-EGFP. Using the pSPV-EGFP, two recombination cassettes pSPV-113LF-EGFP-113RF and pSPV-116LF-EGFP-116RF were constructed by cloning the flanking regions of the ORFV113 and ORFV116 and inserted into two MCS flanking the EGFP gene. Using this novel system, two single gene deletion mutants OV-IA82Δ113 and OV-IA82Δ116 were successfully generated. Conclusions This approach shortens the time needed to generate recombinant ORFVs (rORFVs. Thus, the pSPV-EGFP vector provides a direct, fast, and convenient way to manipulate the recombinant viruses, indicating that it is highly suited for its designed purpose.

    Education is a major force for economic and social wellbeing. Despite high aspirations, education at all levels can be expensive and ineffective. Three Grand Challenges are identified: (1) enable people to learn orders of magnitude more effectively, (2) enable people to learn at orders of magnitude less cost, and (3) demonstrate success by exemplary interdisciplinary education in complex systems science. A ten year `man-on-the-moon' project is proposed in which FuturICT's unique combination of Complexity, Social and Computing Sciences could provide an urgently needed transdisciplinary language for making sense of educational systems. In close dialogue with educational theory and practice, and grounded in the emerging data science and learning analytics paradigms, this will translate into practical tools (both analytical and computational) for researchers, practitioners and leaders; generative principles for resilient educational ecosystems; and innovation for radically scalable, yet personalised, learner engagement and assessment. The proposed Education Accelerator will serve as a `wind tunnel' for testing these ideas in the context of real educational programmes, with an international virtual campus delivering complex systems education exploiting the new understanding of complex, social, computationally enhanced organisational structure developed within FuturICT.

  19. Improving ICT Governance by Reorganizing Operation of ICT and Software Applications: The First Step to Outsource

    Science.gov (United States)

    Johansson, Björn

    During recent years great attention has been paid to outsourcing as well as to the reverse, insourcing (Dibbern et al., 2004). There has been a strong focus on how the management of software applications and information and communication technology (ICT), expressed as ICT management versus ICT governance, should be carried out (Grembergen, 2004). The maintenance and operation of software applications and ICT use a lot of the resources spent on ICT in organizations today (Bearingpoint, 2004), and managers are asked to increase the business benefits of these investments (Weill & Ross, 2004). That is, they are asked to improve the usage of ICT and to develop new business critical solutions supported by ICT. It also means that investments in ICT and software applications need to be shown to be worthwhile. Basically there are two considerations to take into account with ICT usage: cost reduction and improving business value. How the governance and management of ICT and software applications are organized is important. This means that the improvement of the control of maintenance and operation may be of interest to executives of organizations. It can be stated that usage is dependent on how it is organized. So, if an increase of ICT governance is the same as having well-organized ICT resources, could this be seen as the first step in organizations striving for external provision of ICT? This question is dealt with to some degree in this paper.

    2009-01-01

    Full Text Available Abstract Current radio frequency power amplifiers in 3G base stations have very high power consumption leading to a hefty cost and negative environmental impact. In this paper, we propose a potential architecture design for future wireless base station. Issues associated with components of the architecture are investigated. The all-digital transmitter architecture uses a combination of envelope elimination and restoration (EER and pulse width modulation (PWM/pulse position modulation (PPM modulation. The performance of this architecture is predicted from the measured output power and efficiency curves of a GaN amplifier. 57% efficiency is obtained for an OFDM signal limited to 8 dB peak to average power ratio. The PWM/PPM drive signal is generated using the improved Cartesian sigma delta techniques. It is shown that an RF oversampling by a factor of four meets the WLAN spectral mask, and WCDMA specification is met by an RF oversampling of sixteen.

  13. ICT Definition Implication on ICT Career Choice and Exclusion among Women

    Directory of Open Access Journals (Sweden)

    Muchiri Michael Njoki

    2016-05-01

    Full Text Available ICT is driving all areas of the economy and is likely to dictate the future for all genders. The narrow definition of ICT has greatly impacted on the female gender choosing ICT as a career of choice. There are few women in the ICT careers. The study sought to determine the nature of ICT career gender exclusion, status and trend of ICT job opportunities, source of ICT gender career exclusion and the contribution of the narrow definition to the exclusion. A mixed method of survey and desktop method was employed in this study. A structured questionnaire was used in this study in order to identify the factors that influence ICT career choice amongst Kenyan lady students. A purposive sample of Information Technology and Computer Science undergraduate university students (77 females, 56 males; age range 17 to 35 years and 10 postgraduate students in Information Technology from two public universities participated in the study. The paper discusses the emerging unfilled ICT jobs. The study established that the narrow definition negatively influences ICT as a career of Choice among girls. Broadening ICT definition to include ICT related careers that have more social rather than technical aspect accordingly is likely to influence more women to join the field.

    Albariño, César G., E-mail: calbarino@cdc.gov; Wiggleton Guerrero, Lisa; Lo, Michael K.; Nichol, Stuart T.; Towner, Jonathan S.

    2015-10-15

    Previous studies have demonstrated the potential application of reverse genetics technology in studying a broad range of aspects of viral biology, including gene regulation, protein function, cell entry, and pathogenesis. Here, we describe a highly efficient reverse genetics system used to generate recombinant Ebola virus (EBOV) based on a recent isolate from a human patient infected during the 2014–2015 outbreak in Western Africa. We also rescued a recombinant EBOV expressing a fluorescent reporter protein from a cleaved VP40 protein fusion. Using this virus and an inexpensive method to quantitate the expression of the foreign gene, we demonstrate its potential usefulness as a tool for screening antiviral compounds and measuring neutralizing antibodies. - Highlights: • Recombinant Ebola virus (EBOV) derived from Makona variant was rescued. • New protocol for viral rescue allows 100% efficiency. • Modified EBOV expresses a green fluorescent protein from a VP40-fused protein. • Modified EBOV was tested as tool to screen antiviral compounds and measure neutralizing antibodies.

  9. Gold nanoparticles generated through "green route" bind Hg2+ with a concomitant blue shift in plasmon absorption peak.

    Science.gov (United States)

    Radhakumary, C; Sreenivasan, K

    2011-07-21

    We discuss here a quick, simple, economic and ecofriendly method through a completely green route for the selective detection of Hg(2+) in aqueous samples. Here we exploited the ability of chitosan to generate gold nanoparticles and subsequently to act as a stabilizer for the formed nanoparticles. When chitosan stabilized gold nanoparticles (CH-Au NPs) are interacted with Hg(2+) a blue shift for its localized surface plasmon resonance absorbance (LSPR) band is observed. The blue shift is reasoned to be due to the formation of a thin layer of mercury over gold. A concentration as low as 0.01 ppm to a maximum of 100 ppm Hg(2+) can be detected based on this blue shift of the CH-Au NPs. While all other reported methods demand complex reaction steps and costly chemicals, the method we reported here is a simple, rapid and selective approach for the detection of Hg(2+). Our results also show that the CH-Au NPs have excellent selectivity to Hg(2+) over common cations namely, Pb(2+), Cd(2+), Mn(2+), Fe(2+), Ag(1+), Ce(4+), Ni(2+), and Cu(2+).

  10. An Uncontrolled Item of Enterprise ICT Innovation: the High Level Digital Divide

    Directory of Open Access Journals (Sweden)

    Maurizio Pighin

    2008-06-01

    Full Text Available The globalization phenomena strongly stresses western countries’ economies. Especially in industrial districts, companies are reacting with continuous innovations in product and process, based mainly on the introduction of ICT. This continuous organizational change process forces employees to keep in touch with the working environment in an endless learning process. Therefore, the introduction of new ICT seems to bring a cultural development for individuals. Is this always true? Our conviction is that the strong ICT impact generates a new form of digital-divide, a “High-Level Digital Divide” (HLDD: an increasing cultural distance between people able to follow the enterprise ICT evolution and complexity, and people with a lower cultural growth ability. An uncontrolled growth of HLDD may limit the evolution capacity of the enterprise and drop out people from labor market.

  11. How the Use of ICT can Contribute to a Misleading Picture of Conditions – A Five-Step Process

    Directory of Open Access Journals (Sweden)

    Stefan Holgersson

    2015-11-01

    Full Text Available This paper contributes to the limited research on roles ICT can play in impression-management strategies and is based on case studies done in the Swedish Police. It also gives a theoretical contribution by adopting a holistic approach to explain how ICT can contribute to giving a misleading picture of conditions. Output generated by ICT has nowadays a central role in follow-up activities and decision-making. Even if this type of output, often in colourful, presentable, graphical arrangements, gives the impression of being accurate and reliable there is a risk of defective data quality. The phenomena can be described as a process divided into five steps. The first step is about how the data is generated and/or collected. The second step is linked to how the data is registered. The third step is about the output generated from the ICT-systems. The fourth step is how the output of ICT is selected for presentation. The fifth step concerns how output generated by ICT is interpreted. This paper shows that ICT can easily be used in impression-management strategies. For example, that personnel take shortcuts to affect the statistics rather than applying methods that may give the desired effects.

    Multiple patterning ArF immersion lithography has been expected as the promising technology to satisfy tighter leading edge device requirements. One of the most important features of the next generation lasers will be the ability to support green operations while further improving cost of ownership and performance. Especially, the dependence on rare gases, such as Neon and Helium, is becoming a critical issue for high volume manufacturing process. The new ArF excimer laser, GT64A has been developed to cope with the reduction of operational costs, the prevention against rare resource shortage and the improvement of device yield in multiple-patterning lithography. GT64A has advantages in efficiency and stability based on the field-proven injection-lock twin-chamber platform (GigaTwin platform). By the combination of GigaTwin platform and the advanced gas control algorithm, the consumption of rare gases such as Neon is reduced to a half. And newly designed Line Narrowing Module can realize completely Helium free operation. For the device yield improvement, spectral bandwidth stability is important to increase image contrast and contribute to the further reduction of CD variation. The new spectral bandwidth control algorithm and high response actuator has been developed to compensate the offset due to thermal change during the interval such as the period of wafer exchange operation. And REDeeM Cloud™, new monitoring system for managing light source performance and operations, is on-board and provides detailed light source information such as wavelength, energy, E95, etc.

    This study examines the reorganisation of the administration of admission to higher education in Norway, which has also included the development of a nationwide, ICT-based case handling system. This reform process was initiated out of the need to provide politicians with information for control and regulatory purposes, and the reform resulted in a centralised management information system. This system, however, has evolved into a coordinated but also partly locally delegated decision-making instrument which processes most of the applications for admission to higher education in Norway.

    We report on the generation of the second (515 nm) and fourth (257.5 nm) harmonics from a 100 kHz diode-pumped solid-state laser operating at a wavelength of 1030 nm which uses one Yb:YAG thin disk in the regenerative amplifier and delivers 60 W of the average output power in pulses of 4 ps duration. Thirty-five W in green light and 6 W in deep ultraviolet (DUV) were achieved. The sensitivity of the second harmonic generation efficiency toward the lithium triborate crystal temperature is demonstrated in experiment. The overall conversion efficiency from NIR to DUV of 10% was achieved. The β-barium borate and cesium lithium borate crystals were used as green to DUV convertors and compared regarding the efficiency and spectral bandwidths. The achieved output power is unique for DUV picosecond pulses.

    Full Text Available This paper presents studies of wooden installations which use the power of water flows for electric power generation and for other industrial activities. This paper focuses on the historical context as well by identifying the places where wooden installations have worked since the 15th century, in the Fagaras Mountains foothills, on the Berivoi River valley, by using the power of water flows for timber production activities, fulling mills and mills. The paper also aims through the archaeological sites which contain important material and highlight the traditions of the Romanian nation around these places and the development of these old craft techniques from ancient times. Apart the identification of these sites (which are not found on any map, other places with hydropower potential are rediscovered, and by using some low investments, they may become centres to produce electricity needed for holiday dwellings, guesthouses, agricultural and livestock facilities located far away from the power station. The implementation of 'green energy' which generates systems by using wood installations as mechanical subsystems of water flow energy conversion, in combination with modern subsystems of conversion, storage and transport, as well as the development of some integrated modules (hydroelectric, photovoltaic and eoalian represent the optimal solution that contribute to the development of foothill areas, in the context of promotion of the Romanian traditional spirituality and the development of sustainable programs. This paper proposes solutions to promote the small hydroelectric power stations on the watercourses of mountains and foothills regions by using fractions of minimum water flows thereof, of maintaining a water flow on the main valley as well, so as the aquatic fauna permanently regenerate, and to protect the specificity of the environment and of the surrounding areas.

    Full Text Available With increasing life expectancy and growth of knowledge and information, ICT enable elderly people to increase and improve their individual and social development and optimize their quality of life from a technical, economic, political and cultural viewpoint.The present study aims to analyze the use that elderly people make of ICT. The method used for the study is descriptive using the questionnaire technique to verify the knowledge that elderly people have on ICT, interest, tools and difficulties of access.Results show that elderly people consider poor their ICT skills, using them primarily to communicate with friends and family. Most of them can use the e-mail, can open, print and attach a file and use Internet search engines to find information, the lowest values are associated with spreadsheets, databases and statistical packages. They consider ICT as being useful to help building communication, developing integration, generating information among people and improving intergenerational relationship, gathering information not readily accessible by other means and learning new skills. They have no fear when using them, consider attainable their learning and see many possibilities in its use and therefore worth spending time and effort but feel that society is too dependent on computers. In conclusion, we consider essential to improve access for elderly people to ICT as an important tool for improving their quality of life and there are no major difficulties for effective management.

    2010-02-01

    Full Text Available This article aims to define a theoretical explanatory framework for the integration of information technologies and communication technologies (ICT in education from the perspective of teacher education. The initial and continuing training of teachers is characterized by a tendency towards "essentialisation" of technology and generation of users who do not usually think about educational uses of technology in their own contexts. Our research on the integration of ICT in the classroom has allowed us to observe the lack of connection between the personal and professional use of teachers of these technological tools, as well as the need for training is geared towards developing skills and knowledge to examine, in a critical manner, the educational implications of these new teaching aids. This article is based on the proposed Koehler & Mishra (2005, 2006, 2007 and 2008 called TPCK (Technological Pedagogical Content Knowledge which is based on the construct of PCK Shulman (1987 to which is added the concept of "Technology" (T to those of "Pedagogy" (P and "Curriculum Content" (C.

    Full Text Available Information and Communication Technologies (ICTs have contributed in one way or the other to many transformations in contemporary society. The contexts and the impacts of such transformations are particularly significant for developing societies like India. The relevance of new computing technologies and their effective implementation in developing countries is widely debated, both at policy and community level. Needless to say, FOSS (Free Open Source Software has encouraged the participation of civil society, creating potential for developing specific information technology tools. In this context, the OSCAR-project (Open Source Simple Computer for Agriculture in Rural Areas is an initiative from European and South Asian Institutions to assist decision making in agriculture. OSCAR developed a weed identification system for the major weed species in rice-wheat cropping systems of the Indo-Gangetic Plains (IGPs covering Pakistan, India, Nepal and Bangladesh. An integral part of the OSCAR-project is its applicability to three categories of potential users: farmers, extension officers, and, scientists and students in agricultural sciences. OSCAR was evaluated through extensive interactions with farmer groups, extension personnel, IT specialists, NGO and UN staff, government officials, scientific researchers and PhD students in various disciplines and MSc students from various programs in all the four IGP countries. The experience from OSCAR is helpful in understanding the larger contexts and the impact of ICT interventions in an interdisciplinary framework.

    Wang, Chengan; Tan, Jianyu; Lai, Qingzhi

    2016-12-01

    The “blue-green window” in the ocean plays an important role in functions such as communication between vessels, underwater target identification, and remote sensing. In this study, the transmission process of blue-green light in the upper ocean is analyzed numerically using the Monte Carlo method. First, the effect of total number of photons on the numerical results is evaluated, and the most favorable number is chosen to ensure accuracy without excessive costs for calculation. Then, the physical and mathematical models are constructed. The rough sea surface is generated under windy conditions and the transmission signals are measured in the far field. Therefore, it can be conceptualized as a 1D slab with a rough boundary surface. Under windy conditions, these bubbles form layers that are horizontally homogeneous and decay exponentially with depth under the influence of gravity. The effects of bubble populations on the process of blue-green light transmission at different wind speeds, wavelengths, angle of incidence and chlorophyll-a concentrations are studied for both air-incident and water-incident cases. The results of this study indicate that the transmission process of blue-green light is significantly influenced by bubbles under high wind-speed conditions.

    Sun, Jian; Xu, Chanqing

    2012-06-01

    We report high-power efficient green light generation by frequency doubling from a periodically poled MgO doped LiNbO(3) ridge waveguide. The ridge waveguide is fabricated by the annealed proton-exchanging and precise diamond blade dicing techniques. The ridge structure exhibits a surface roughness of only 3.7 nm, and near-90° vertical sidewall. The total insertion loss of an 8.5 µm wide and 1.4 cm long uncoated waveguide is 3.0 dB under direct fiber coupling. 466 mW of continuous-wave green light with an optical-to-optical conversion efficiency of 69.7% is obtained. To the best of our knowledge, this is the highest green light output power reached to date using a ridge-type LiNbO(3) waveguide device. Phase-matching temperature shift, tuning curve distortion, and waveguide loss increase are observed under high power operation. Our analysis shows that the photorefractive effect and the green induced infrared absorption are responsible for the observed phenomena, which becomes prominent under several megawatt per square centimeter power density.

    Full Text Available Understanding about the objectives of ICT literacy and the ways in which it should be enhanced vary. A comprehensive theoretical framework for the analysis of notions of ICT literacy is presented. Current notions of ICT literacy in different segments of policymaking and implementation in Australia are analysed and compared. Two dimensions (intended and implemented and three theoretical perspectives (ICT policy, literacy policy and teaching and learning are covered in this analysis. Similarities and differences in the understanding of ICT literacy at the national and regional levels and in various segments of decision-making and implementation are revealed. The complexity of the ICT literacy phenomenon is described. It is shown that, at the intended level, the formation of the notion of ICT literacy is strongly influenced by thinking about ICT literacy in ICT and educational policies. At the implemented level, the notion of ICT literacy is strongly influenced by various local factors and even implementation routines.

  18. ACHIEVING VALUE FROM ICT IN SMES: KEY MANAGEMENT STRATEGIES

    Directory of Open Access Journals (Sweden)

    K. Johnston

    2009-01-01

    Full Text Available ICT covers a broad range of fields in business and therefore makes ICT value difficult to simply define. The main factors that influence the use of ICT are therefore important to look at, as they give a good understanding of the how much influence the organisation has, on achieving value in its given context. The transformational model of ICT use was analysed to establish how SMEs in South Africa achieve business value from ICT and what management practices are most effective. Implications of the research are that management practices are an important factor that influences the value from ICT, and that the more management practices organisations implement, the greater the business value from ICT. Further findings of this study deduced that organisations that are more ICT aware, gain greater business value from ICT, with value achievement from ICT largely within the organisation’s control. This paper concludes with recommendations for future research.

    2012-03-01

    Laser displays require red, green and blue (RGB) laser sources each with a low-cost, a high wall-plug efficiency, and a small size. However, semiconductor chips that directly emit green light with sufficient power and efficiency are not currently available on the market. A practical solution to the "green" bottleneck is to employ diode pumped solid state laser (DPSSL) technology, in which a frequency doubling crystal is used. In this paper, recent progress of MgO doped periodically poled lithium niobate (MgO:PPLN) frequency doubling optical chips will be presented. It is shown that MgO:PPLN can satisfy all of the requirements for laser displays and is ready for mass production.

    Full Text Available Nowadays, most of the IT (Information Technology and ICT (Information and Communication Technology industries are practicing sustainability under green computing hoods. Users/Customers are also moving towards a new sustainable society. Therefore, while getting or providing different services from different ICT vendors, Service Level Agreement (SLA becomes very important for both the service providers/vendors and users/customers. There are many ways to inform users/customers about various services with its inherent execution functionalities and even non-functional/Quality of Service (QoS aspects through SLAs. However, these basic SLAs actually do not cover eco-efficient green issues or ethical issues for actual sustainable development. That is why green SLA (GSLA should come into play. GSLA is a formal agreement incorporating all the traditional/basic commitments as well as respecting the ecological, economical and ethical aspects of sustainability. This research would survey on different basic SLA parameters for various services in ICT industries. At the same time, this survey would focus on finding the gaps and incorporating basic SLA parameters with existing green computing issues and ethical issues for different services in various computing domains. This research defines future GSLA in relationship with ICT product life and three pillars of sustainability. The proposed definition and overall survey could help different service providers/vendors to define their future GSLA as well as business strategies for this new transitional sustainable society.

    Investigations were conducted into the above in some leading OECD (Organization for Economic Cooperation and Development) member states. Green chemistry is a new concept in which clean technology, environment-friendly chemistry, and the like are combined, and is a chemical solution for reducing or stopping the use or generation of materials, products, by-products, solvents, reagents, etc., which are dangerous to health and environments, throughout the whole life cycle of chemicals covering the processes of their designing, manufacturing, dumping, and recycling. In this fiscal year, the actual state of the generation of biomass, regarded as representative of reproducible materials, and its feasibility as chemical resources were investigated. In an effort at finding out chemical reactions safer to health and causing less environmental impact, investigations were also conducted into the recent trends of catalysts, novel reactions for organic syntheses, use of supercritical fluids, photocatalysts, biomimetic processes, etc. The development of substitutes for plastic additives was also studied. Since acceptance by the citizenry is quite important for green chemistry to take effect, educating and enlightening activities in the U.S., Britain, France, and Germany were inquired into. (NEDO)

    We present a micro-integrated laser module based on an amplified diode laser and second harmonic generation which is a promising candidate for a green light source in next-generation 3D holographic displays. The light emitted by the amplified laser has a wavelength of 1064 nm, reaches a power up to 8.2 W and has a long coherence length of >400 m. For second harmonic generation, we tested two geometries of periodically poled lithium niobate crystals in single pass: a bulk crystal and a planar waveguide crystal. With the planar waveguide crystal, we achieve an output power >900 mW and a coherence length >20 m at a wavelength of 532 nm.

  13. Survival of the project: a case study of ICT innovation in health care.

    Science.gov (United States)

    2015-05-01

    From twenty years of information and communication technology (ICT) projects in the health sector, we have learned one thing: most projects remain projects. The problem of pilotism in e-health and telemedicine is a growing concern, both in medical literature and among policy makers, who now ask for large-scale implementation of ICT in routine health service delivery. In this article, we turn the question of failing projects upside down. Instead of investigating the obstacles to implementing ICT and realising permanent changes in health care routines, we ask what makes the temporary ICT project survive, despite an apparent lack of success. Our empirical material is based on Norwegian telemedicine. Through a case study, we take an in-depth look into the history of one particular telemedical initiative and highlight how ICT projects matter on a managerial level. Our analysis reveals how management tasks were delegated to the ICT project, which thus contributed to four processes of organisational control: allocating resources, generating and managing enthusiasm, system correction and aligning local practice and national policies. We argue that the innovation project in itself can be considered an innovation that has become normalised in health care, not in clinical, but in management work. In everyday management, the ICT project appears to be a convenient tool suited to ease the tensions between state regulatory practices and claims of professional autonomy that arise in the wake of new public management reforms. Separating project management and funding from routine practice handles the conceptualised heterogeneity between innovation and routine within contemporary health care delivery. Whilst this separation eases the execution of both normal routines and innovative projects, it also delays expected diffusion of technology.

    Science.gov (United States)

    Yao, Yuhong; Knox, Wayne H.

    2015-03-01

    We report the optical system design of a novel speckle-free ultrafast Red-Green-Blue (RGB) source based on angularly multiplexed simultaneous second harmonic generation from the efficiently generated Stokes and anti-Stokes pulses from a commercially available photonic crystal fiber (PCF) with two zero dispersion wavelengths (TZDW). We describe the optimized configuration of the TZDW fiber source which supports excitations of dual narrow-band pulses with peak wavelengths at 850 nm, 1260 nm and spectral bandwidths of 23 nm, 26 nm, respectively within 12 cm of commercially available TZDW PCF. The conversion efficiencies are as high as 44% and 33% from the pump source (a custom-built Yb:fiber master-oscillator-power-amplifier). As a result of the nonlinear dynamics of propagation, the dual pulses preserve their ultrashort pulse width (with measured autocorrelation traces of 200 fs and 227 fs,) which eliminates the need for dispersion compensation before harmonic generation. With proper optical design of the free-space harmonic generation system, we achieve milli-Watt power level red, green and blue pulses at 630 nm, 517 nm and 425 nm. Having much broader spectral bandwidths compared to picosecond RGB laser sources, the source is inherently speckle-free due to the ultra-short coherence length (99.4% excitation purities of the three primaries, leading to the coverage of 192% NTSC color gamut (CIE 1976). The reported RGB source features a very simple system geometry, its potential for power scaling is discussed with currently available technologies.

    2012-11-01

    Modern ICT (Information and Communication Technology) has developed a vision where the "computer" is no longer associated with the concept of a single device or a network of devices, but rather the entirety of situated services originating in a digital world, which are perceived through the physical world. It is observed that services with explicit user input and output are becoming to be replaced by a computing landscape sensing the physical world via a huge variety of sensors, and controlling it via a plethora of actuators. The nature and appearance of computing devices is changing to be hidden in the fabric of everyday life, invisibly networked, and omnipresent, with applications greatly being based on the notions of context and knowledge. Interaction with such globe spanning, modern ICT systems will presumably be more implicit, at the periphery of human attention, rather than explicit, i.e. at the focus of human attention.Socio-inspired ICT assumes that future, globe scale ICT systems should be viewed as social systems. Such a view challenges research to identify and formalize the principles of interaction and adaptation in social systems, so as to be able to ground future ICT systems on those principles. This position paper therefore is concerned with the intersection of social behaviour and modern ICT, creating or recreating social conventions and social contexts through the use of pervasive, globe-spanning, omnipresent and participative ICT.

  2. ICT in Chilean Schools: Students' and Teachers' Access and Use of ICT

    Directory of Open Access Journals (Sweden)

    J. Enrique Hinostroza

    2005-01-01

    Full Text Available This paper presents the results of the analysis of the data from a national survey of the Chilean educational ICT infrastructure and its use in schools implemented by the Centre for Technology and Education of the Chilean Ministry of Education in 2004. Results show that the context of ICT use in Chilean schools can be characterized as relatively good, insofar as there are no first-order barriers for implementing ICT pedagogy. In this context, students’ ICT use can be categorized based on four factors: communication, productivity, recreation, and communication with teachers. On the other hand, teachers’ ICT use can be categorized using three factors: communication, teaching, and technical. Based on these factors and considering the availability and use of ICT in schools, the question remains how to make this time most effective for improving students’ learning. Additionally, results show that students, on their own, spend a considerable amount of time developing activities described as communication. The question that arises from this finding is how to take advantage of these activities in order to meet teaching and learning aims. Regarding teachers, results open possibilities for redesigning professional development courses by taking advantage of what they already do with ICT.

    Depression is expected to be the disorder with the highest disease burden in high-income countries by the year 2030. ICT4Depression (ICT4D) is a European FP7 project, which aims to contribute to the alleviation of this burden by making use of depression treatment and ICT innovations. In this project we developed an ICT-based system for use in primary care that aims to improve access as well as actual care delivery for depressed adults. Innovative technologies within the ICT4D system include 1) flexible self-help treatments for depression, 2) automatic assessment of the patient using mobile phone and web-based communication 3) wearable biomedical sensor devices for monitoring activities and electrophysiological indicators, 4) computational methods for reasoning about the state of a patient and the risk of relapse (reasoning engine) and 5) a flexible system architecture for monitoring and supporting people using continuous observations and feedback via mobile phone and the web. The general objective of the ICT4D project is to test the feasibility and acceptability of the ICT4D system within a pilot study in the Netherlands and in Sweden during 2012 and 2013.

To promote innovation in Saudi Arabia, for instance, it is necessary to support inventors’ ideas to turn inventions into start-up companies, which are companies in their early stage. At the same time, it seems that there is a need for more academic research to study the success factors of Saudi information and communication technology (ICT start-up companies. ICT start-ups are important to the economy because they are needed for the progress of all industries. Therefore, this study will identify the factors that lead to successful ICT start-up projects. Then, it will develop a model for the best practices in the interplay among the defined factors that will increase the opportunity to initiate successful start-ups. This research involves a factor analysis study based on a quantitative method to measure the interdependences among the success factors for ICT start-ups. The identified factors are verified using a sample of Saudi start-up companies. The study will contribute to enhancing the technological content to diversify the Saudi economy in order to prepare for the post-oil era. The study result is a survivability model for Saudi-incubated ICT startups. The resulting model has two phases, as follows: (1 the incubation period, which includes the relationships among three factors leading to constant and successful updates and upgrades of the ICT startup business model; and (2 the postincubation period, which include relationships among the three factors that help to deal with the changing nature of the market and the emergence of competing products. This solution can be applied within startups with similar conditions.

  18. TEACHERS IN THE ERA OF ACCELERATION : How the acceleration of ICT developments influences the ICT use by teachers at school

    OpenAIRE

    Charalambous, Georgios

    2015-01-01

    In the effort to examine the factors that impact the use of ICT by teachers, research has up until now neglected the acceleration of ICT developments as a factor that affects the successful integration of ICT in education. The technological acceleration in general has triggered significant changes at the social level, such as the acceleration of social change and the acceleration of the pace of life. This is why the study of the acceleration of ICT provides for a good theoretical framework to...

    Day, Arla; Paquet, Stephanie; Scott, Natasha; Hambley, Laura

    2012-10-01

    Although many employees are using more information communication technology (ICT) as part of their jobs, few studies have examined the impact of ICT on their well-being, and there is a lack of validated measures designed to assess the ICT factors that may impact employee well-being. Therefore, we developed and validated a measure of ICT demands and supports. Using Exploratory Structural Equation Modeling, we found support for 8 ICT demands (i.e., availability, communication, ICT control, ICT hassles, employee monitoring, learning, response expectations, and workload) and two facets of ICT support (personal assistance and resources/upgrades support). Jointly, the ICT demands were associated with increased strain, stress, and burnout and were still associated with stress and strain after controlling for demographics, job variables, and job demands. The two types of ICT support were associated with lower stress, strain, and burnout. Resources/upgrades support moderated the relationship between learning expectations and most strain outcomes and between ICT hassles and strain. Personal assistance support moderated the relationship between ICT hassles and strain.

    2015-08-01

    Nanofibrillated cellulose, a polymer that can be obtained from one of the most abundant biopolymers in nature, is being increasingly explored due to its outstanding properties for packaging and device applications. Still, open challenges in engineering its intrinsic properties remain to address. To elucidate the optical and mechanical stability of nanofibrillated cellulose as a standalone platform, herein we report on three main findings: (i) for the first time an experimental determination of the optical bandgap of nanofibrillated cellulose, important for future modeling purposes, based on the onset of the optical bandgap of the nanofibrillated cellulose film at Eg≈275 nm (4.5 eV), obtained using absorption and cathodoluminescence measurements. In addition, comparing this result with ab-initio calculations of the electronic structure the exciton binding energy is estimated to be Eex≈800 meV; (ii) hydrostatic pressure experiments revealed that nanofibrillated cellulose is structurally stable at least up to 1.2 GPa; and (iii) surface elastic properties with repeatability better than 5% were observed under moisture cycles with changes of the Young modulus as large as 65%. The results obtained show the precise determination of significant properties as elastic properties and interactions that are compared with similar works and, moreover, demonstrate that nanofibrillated cellulose properties can be reversibly controlled, supporting the extended potential of nanofibrillated cellulose as a robust platform for green-technology applications.

    2016-07-01

    This study reports on an on-the-fly green synthesis/dispersion of silver iodide (AgI) nanoparticles from the combustion of AgIO3/carbon black (CB)/nitrocellulose (NC) composites, which could be used as a candidate for a cloud-seeding pyrotechnic. Films were formed by direct electrospray deposition of a mixture of synthesized silver iodate with CB and NC. The decomposition pathways of AgIO3/CB and AgIO3/CB/NC were evaluated by temperature jump time of flight mass spectrometry (T-jump TOFMS) and XRD, showing that AgI particles and CO2 are released from the reaction between AgIO3 and CB without other toxic residuals. The flame propagation velocity of AgIO3/CB/NC films increases with the increasing of particle mass loading of AgIO3 and CB and peaks at 40 wt%, which is much higher than that of an AgI/AP/NC film. The mean diameter of the resultant AgI nanoparticles is from 51 to 97 nm. The mass loading of AgIO3 and CB was found to play a major role in size control of the AgI nanoparticles.

    2011-01-01

    Full Text Available Green Computing is one of the emerging computing technology in the field of computer science engineering and technology to provide Green Information Technology (Green IT. It is mainly used to protect environment, optimize energy consumption and keeps green environment. Green computing also refers to environmentally sustainable computing. In recent years, companies in the computer industry have come to realize that going green is in their best interest, both in terms of public relations and reduced costs. Information and communication technology (ICT has now become an important department for the success of any organization. Making IT “Green” can not only save money but help save our world by making it a better place through reducing and/or eliminating wasteful practices. In this paper we focus on green computing by optimizing operating systems and scheduling of hardware resources. The objectives of the green computing are human power, electrical energy, time and cost reduction with out polluting the environment while developing the software. Operating System (OS Optimization is very important for Green computing, because it is bridge for both hardware components and Application Soft wares. The important Steps for green computing user and energy efficient usage are also discussed in this paper.

    Full Text Available The paper includes analysis and assessment of trade in the ICT services performance of Poland. This study is looked at the trade position, essentially on the basis of the share in the world ICT services exports, revealed comparative advantage (RCA, and trade coverage ratio. It also identifies trends of the world trade in the ICT services. The statistics are derived from the basis of UNCTAD and Eurostat. International trade in the ICT ser-vices sector has specific characteristics and the interpretation of results of this trade is to take account of the particular nature of the ICT services. Poland is currently not revealed comparative advantage in the ICT services exports, but has had positive balance. Practically all trade indicators for Poland show very strong growth, which indicate a significant improvement in its ICT services trade position.

  13. ICT Practice in Morocco’s innovative teachers

    Directory of Open Access Journals (Sweden)

    Ahmed Lablidi

    2013-01-01

    Full Text Available The integration of Information and communication technology (ICT in Moroccan schools forms one of the strategic levers of Ministry of National Education (MNE to improve the quality of teaching and learning. Thus, the training teacher actions to the use of ICT in the classroom, the creation of institutional structures and the introduction of incentives for innovation in ICT accounted for the actions taken by the MNE to support teachers and help them to appropriate ICT tools and using them in their courses. Some teachers have more or less successful betting. This observation led us to question ourselves about the integration process of ICT which enabled them to distinguish themselves from the masses. The laid hypothesis is that the ICTs appropriation and their use in teaching practices is the result of a process that is located on a continuum ranging from non-use of ICT in their regular use.

    2009-07-01

    Full Text Available In step with introduction of ICT in Educational system and equipping schools with computers and training teachers to use it, there is a question of why ICT application in schools is just inching ahead? It seems that the role of high school principles, their attitude as well as regulations pertinent to ICT implementation could be very effective in using computers at schools. The present investigation intends to study this. A Survey was carried using a 37 member sample randomly drawn from principles of high schools situated in the city of Isfahan that had an ICT lab. Findings indicate that principles use computer more as an office tool than a learning facilitator. Moreover, due to paucity of clear and explicit regulations governing ICT use, computer usage in schools has stumbled. This is especially so in schools where in the absence of a full time computer administrator, the existing facilities are under used. Meanwhile, principles’ attitude towards ICT was gauged as being positive

    While development of science and technology has built up the sophisticated civilized society, it has also resulted in quite a few disadvantages in global environment and human society. The common recognition has been increasingly shared worldwide on sustainable development society attaching greater importance to the symbiotic relationship with nature and social ethics. After the East Japan Great Earthquake, it is indispensable for sustainable social development to enhance capacity of resistance and restoration of society against natural disaster, so called "resilient society". Our society consists of various Cyber Physical Systems (CPSs) that make up the physical systems by fusing with an Information Communication Technology (ICT). We describe the proposed structure of CPS in order to realize resilient society. The configuration of resilient CPS consisting of ICT and physical system is discussed to introduce "autonomous, distributed, and cooperative" structure, where subsystems of ICT and physical system are simultaneously coordinated and cooperated with Business Continuity Planning (BCP) engine, respectively. We show the disaster response information system and energy network as examples of BCP engine and resilient CPS, respectively. We also propose the structure and key technology of resilient ICT.

    The Franciscan Complex accretionary prism was assembled during an ∼165-m.y.-long period of subduction of Pacific Ocean plates beneath the western margin of the North American plate. In such fossil subduction complexes, it is generally difficult to reconstruct details of the accretion of continent-derived sediments and to evaluate the factors that controlled accretion. New detrital zircon U-Pb ages indicate that much of the major Coastal belt subunit of the Franciscan Complex represents a massive, relatively brief, surge of near-trench deposition and accretion during Eocene time (ca. 53–49 Ma). Sediments were sourced mainly from the distant Idaho Batholith region rather than the nearby Sierra Nevada. Idaho detritus also fed the Great Valley forearc basin of California (ca. 53–37 Ma), the Tyee forearc basin of coastal Oregon (49 to ca. 36 Ma), and the greater Green River lake basin of Wyoming (50–47 Ma). Plutonism in the Idaho Batholith spanned 98–53 Ma in a contractional setting; it was abruptly superseded by major extension in the Bitterroot, Anaconda, Clearwater, and Priest River metamorphic core complexes (53–40 Ma) and by major volcanism in the Challis volcanic field (51–43 Ma). This extensional tectonism apparently deformed and uplifted a broad region, shedding voluminous sediments toward depocenters to the west and southeast. In the Franciscan Coastal belt, the major increase in sediment input apparently triggered a pulse of massive accretion, a pulse ultimately controlled by continental tectonism far within the interior of the North American plate, rather than by some tectonic event along the plate boundary itself.

  15. Green, red and IR frequency comb line generation from single IR pump in AlN microring resonator

    CERN Document Server

    Jung, Hojoong; Guo, Xiang; Fischer, Debra; Tang, Hong X

    2014-01-01

    On-chip frequency comb generations enable compact broadband sources for spectroscopic sensing and precision spectroscopy. Recent microcomb studies focus on infrared spectral regime and have difficulty in accessing visible regime. Here, we demonstrate comb-like visible frequency line generation through second, third harmonic, and sum frequency conversion of a Kerr comb within a high Q aluminum nitride microring resonator pumped by a single telecom laser. The strong power enhancement, in conjunction with the unique combination of Pockels and Kerr optical nonlinearity of aluminum nitride, leads to cascaded frequency conversions in the visible spectrum. High-resolution spectroscopic study of the visible frequency lines indicates matched free spectrum range over all the bands. This frequency doubling and tripling effect in a single microcomb structure offers great potential for comb spectroscopy and self-referencing comb.

  16. Ultrafast, green third-harmonic generation and strong-field phenomena in silicon-on-insulator nanoplasmonic waveguides

    CERN Document Server

    Sederberg, Shawn

    2013-01-01

    The emergence of strong-field nanoplasmonics brings extreme laser field-matter interaction into the realm of nanoscale science, unveiling exciting new physics. Highly nonlinear interaction is enabled by tightly confined electric fields in nanoplasmonic structures, permitting use of optical fields from low-power laser oscillators. Here, we report the first demonstration of visible 517nm third harmonic generation in ultracompact nanoplasmonic waveguides on a silicon-on-insulator platform at an unprecedented conversion efficiency of ~10^{-5}. Exponential growth of broadband white light generation confirms a new strong-field phenomenon of ponderomotive force-driven electron avalanche multiplication. Using time-resolved experiments, we show that the strong nanoplasmonic field confinement allows nonlinear interaction to occur on an ultrafast timescale of 1.98 +/- 0.40 ps, despite the long free-carrier lifetime in silicon. These findings uncover a new strong-field interaction that can be used in sensitive nanoplasmo...

    2010-10-01

    We use a compact chirped-pulse amplified system to harmonically generate ultrashort pulses for aerosol fluorescence measurements. The seed laser is a compact, all-normal dispersion, mode-locked Yb-doped fiber laser with a 1050 nm center wavelength operating at 41 MHz. Average powers of more than 1.2 W at 525 nm and 350 mW at 262 nm are generated with biofluorescence measurements as it allows faster sampling rates as well as the higher peak powers as compared to previously demonstrated Q-switched systems while maintaining a pulse period that is longer than the typical fluorescence lifetimes. Thus, the fluorescence excitation can be considered to be quasicontinuous and requires no external synchronization and triggering.

    Full Text Available The intensity of ICT usage continues to increase. This should be accompanied  by the increase of the government's performance, and one of the important components is governance of the ICT system planning. The ICT system planning with a good management will provide significant benefits to the organization. One cause of insignificant benefits ICT to the organizational goals is there is no ICT governance applied.  It can be caused by many things, one of them is the lack of knowledge and awareness about the ICT governance, so there are still many government agencies which have not yet implemented properly the ICT governance. By using quantitative approaches, questionnaire instrument was adapted from the General Guide of the National ICT Governance. Framework COBIT and data analysis techniques adopted from the COBIT Maturity level. This study aims to explore the guidelines as an evaluation tool for the governance of the ICT system planning in Department of Communications and Information Technology in Bitung City. The results of this study found that the institution is still at low level, level 1 with 0,63 maturity level in governance planning of ICT system.

    2011-09-01

    Full Text Available Information and Communications Technology (ICT can play a key role in self-access learning and the organization of self-access centres (SACs (Reinders & Lázaro, 2007. The generation of young people currently at university has been labeled “digital natives” (Prensky, 2001, yet it would seem that many of these “natives” in Japan seem to lack the necessary ICT skills to use in the university context (Castellano, Mynard & Rubesch, 2011; Williams, 2011. This paper assesses the current situation of Japanese young people’s pre-university ICT experience and its implications for self-access learning. Do they actually lack the necessary skills to engage with self-access in an ICT context? Or does the reality in fact show that this perception is wrong and if so why? This paper will answer the questions through original research (N=105 and reference to the literature, globally and in Japan. It finds that students have more competence than previously believed and ventures some reasons for this previous misperception.

    Full Text Available This study makes an effort to investigate the effects of Information and Communication Technology (ICT on daily urban travel patterns. The main research question is based on the capability of ICT in reducing trip production (generation and attraction. The results obtained from the analysis of the data extracted from a questionnaire given to a sample population of 300 people from Golestan Town, Shiraz-South of Iran - in 2011 revealed that there is a tendency towards decreasing the amount of urban travels through encouraging virtual travels and telecommuting. Most of the people who answered the questionnaire tend to have an economical approach towards the daily travel patterns through the use of at least one ICT method for special trips. On the other hand, the majority of the people questioned believed that ICT has not been full successful in replacing physical trips to supply various needs and can only be of use as a powerful supplement for the purpose of decreasing the amount of physical trips if the existing services are improved and enjoy a higher level of public satisfaction.

  3. For a Green Stadium: Economic Feasibility of Sustainable Renewable Electricity Generation at the Jeju World Cup Venue

    2016-09-01

    Full Text Available After the 2002 FIFA World Cup in South Korea and Japan, the local governments of South Korea were left in charge of several large-scale soccer stadiums. Although these governments have made significant efforts toward creating profits from the stadiums, it is proving to be too difficult for several administrations to cover their full operational, maintenance, and conservation costs. In order to overcome this problem, one of the governments, Seogwipo City, which owns Jeju World Cup Stadium (JWCS, is attempting to provide an independent renewable electricity generation system for the operation of the stadium. The current study therefore examines potential configurations of an independent renewable electricity generation system for JWCS, using HOMER software. The simulation results yield three optimal system configurations with a renewable fraction of 1.00 and relatively low values for the cost of energy ($0.405, $0.546, and $0.692 per kWh. Through the examination of these three possible optimal configurations, the implications and limitations of the current study are presented.

  4. ICT, Teaching and Leadership: How do Teachers Experience the Importance of ICT-Supportive School Leaders?

    Directory of Open Access Journals (Sweden)

    Ove Edvard Hatlevik

    2012-03-01

    Full Text Available The purpose of this study was to explore the relations between teachers’ experiences with ICT-supportive school leaders, perceived usefulness of computers, perceived learning outcomes for students and teachers' use of computers in their teaching. A total of 386 teachers from a nationwide sample of primary and lower secondary schools participated in the study. The correlation analysis revealed that teachers with higher levels of ICT-supportive leaders reported higher levels of perceived usefulness of computers, perceived learning outcomes for students and more frequent use of computers compared with teachers reporting lower levels of ICT-supportive leaders. Regression analysis indicated that two factors, ICT-supportive school leaders and perceived learning outcomes for students using computers, explained 25 percent of the variation in perceived usefulness of computers. Finally, these two factors, ICT-supportive school leaders and perceived learning outcomes for students using computers, explained 5 percent of the variation in how frequently teachers were using computers for reading and writing. The results indicated a need for further studies in order to examine factors that predict teachers’ use of computers in their teaching.

    2016-01-01

    An increasing number of human activities are studied using data produced by individuals' ICT devices. In particular, when ICT data contain spatial information, they represent an invaluable source for analyzing urban dynamics. However, there have been relatively few contributions investigating the robustness of this type of results against fluctuations of data characteristics. Here, we present a stability analysis of higher-level information extracted from mobile phone data passively produced during an entire year by 9 million individuals in Senegal. We focus on two information-retrieval tasks: (a) the identification of land use in the region of Dakar from the temporal rhythms of the communication activity; (b) the identification of home and work locations of anonymized individuals, which enable to construct Origin-Destination (OD) matrices of commuting flows. Our analysis reveal that the uncertainty of results highly depends on the sample size, the scale and the period of the year at which the data were gathe...

    2017-09-01

    Two perovskite-structure K3B6O10Br1-x Cl x (x  =  0 and 0.5) series nonlinear optical crystals were thoroughly investigated for their picosecond 532 nm laser pulses abilities and high power outputs were achieved via second harmonic generation (SHG) technique for the first time. SHG conversion efficiency of 57.3% with a 13.2 mm length K3B6O10Br (KBB) crystal was achieved using a laser source of pulse repetition rate of 10 Hz and pulse width of 25 ps, which is the highest conversion efficiency of ps visible laser based on KBB crystal. And by employing an 80 MHz, 10 ps fundamental laser beam, maximum power outputs of 12 W with K3B6O10Br0.5Cl0.5 (KBBC) and 11.86 W with KBB crystals were successfully demonstrated. Furthermore, the standard deviation jitters of the average power outputs are less than 0.6% and 1.17% by KBB and KBBC, respectively, showing ultrastable power stabilities favorable for practical applications. In addition, the other optical parameters including acceptance angle and temperature bandwidth were also investigated.

  5. Sediment generation by Halimeda on atoll interior coral reefs of the southern Maldives: A census-based approach for estimating carbonate production by calcareous green algae

    Perry, Chris T.; Morgan, Kyle M.; Salter, Michael A.

    2016-12-01

    Methods for quantifying rates and size fractions of carbonate sand production on reefs remain limited, despite the urgent need for such data to support assessments of reef island and tropical beach-dominated shoreline resilience. Here we present a census-based approach that supports estimates of sediment generation by the calcareous green alga Halimeda spp., which is an often conspicuous reef and lagoon substrate coloniser. Based on data from Kandahalagala (South Huvadhoo atoll, southern Maldives), we present carbonate sediment production data for the two dominant Halimeda spp. (Halimeda macrophysa and Halimeda micronesica) that occur on the reef flat and reef slope habitats. Whilst total mean production rates by Halimeda spp. are similar in both habitats (reef flat average, 67.49 g CaCO3 m- 2 yr- 1; reef slope, 70.89 g), individual species contributions differ markedly. H. micronesica dominates on the reef flat (annual mean 41.91 g CaCO3 m- 2 yr- 1, compared to 25.08 g by H. macrophysa), whilst production is dominated by H. macrophysa on the reef slope (H. macrophysa 40.49 g, H. micronesica 29.01 g CaCO3 m- 2 yr- 1,). In terms of sediment generation we show that these species also contribute very differently to the sediment reservoir. Whilst the sedimentary breakdown products from H. micronesica are somewhat bimodal ( 17% is in the medium to very coarse sand fraction, and 76% in the silt and clay fraction), almost all (> 90%) of the segments produced by H. macrophysa rapidly degrade to silt and clay sized sediment. Based on our census data this suggests that Halimeda spp. will contribute only between 7 and 9 g m- 2 yr- 1 of sand grade sediment on the reef flat and shallow slope habitats, but 55-60 g m- 2 yr- 1 of mud grade sediment. Scaled to the total area of combined reef habitat around Kandahalagala ( 130,583 m2) this equates to Halimeda spp. producing 2192 kg of sand-grade sediment, but 15,181 kg of mud-grade sediment per year. However, sediment compositional

    Full Text Available Theoretical approaches and frameworks which are helpful to understand the use of information and communication technology (ICT in the formal education sector are reviewed and examined. The structured literature review and documentary research techniques are applied. Relationships between ICT, curriculum development, pedagogy, and practice in classroom setting are considered. The term 'ICT', in curriculum is discussed. A framework for the investigation of contemporary understandings of ICT in pedagogical practice is presented. Three dimensions of ICT curriculum: 1 intended; 2 implemented; and 3 achieved are employed in this framework. The structural approaches that can be applied for the examination of ICT in each of these three dimensions are discussed. The proposed is a link between 1 the theoretical approaches and aims that policies integrated ICT, proposed at the top-level of policy making; 2 teaching and learning practices, implemented at the middle-level of educational system; and 3 student's learning outcome, expected at the base-level of educational system. It is argued that this framework can be applied in ICT curriculum. This study will provide a conceptual structure for discovering inconsistencies in the understanding and use of ICT at various levels of educational systems.

    Full Text Available Information and Communication Technology (ICT is increasingly becoming indispensable part of the education system. ICT has changed the style of functioning of the educational system and its governance. This paper considers the rapid spread of ICT applications which has brought drastic technological, social and economic transformations. These changes have caused educational institutions, administrators, teachers to rethink their roles, teaching and vision for the future. The sustainability of a nation in the era of knowledge and its economy depends on the effective educational system. It is considered as the comparative analysis of the inputs and outputs. In educational system, the inputs are teachers, students, classroom materials, equipments of teaching, methods of teaching and the outputs are quantity as well as quality of student learning. The proper integration of ICT with teaching/ learning environment increases the chance of gaining education along with increased productivity. ICT provides various opportunities to learners and make teachers aware of their new roles & responsibilities in educational set up. The growing use of ICT will change many of the strategies employed by both teachers and students in the learning process. The role of ICT in the educational administration is recurring and unavoidable. The paper discusses various functions discharged by ICT in the field of Education and its most new usages. In general, ICT is going to play a vital role in bringing about qualitative change in every aspects of our life.

    Cardiac progenitor cells (CPCs) are committed to the cardiac lineage but retain their proliferative capacity before becoming quiescent mature cardiomyocytes (CMs). In medical therapy and research, the use of human pluripotent stem cell-derived CPCs would have several advantages compared with mature CMs, as the progenitors show better engraftment into existing heart tissues, and provide unique potential for cardiovascular developmental as well as for pharmacological studies. Here, we demonstrate that the CAG promoter-driven enhanced green fluorescence protein (EGFP) reporter system enables the identification and isolation of embryonic stem cell-derived CPCs. Tracing of CPCs during differentiation confirmed up-regulation of surface markers, previously described to identify cardiac precursors and early CMs. Isolated CPCs express cardiac lineage-specific transcripts, still have proliferating capacity, and can be re-aggregated into embryoid body-like structures (CAG-EGFP(high) rEBs). Expression of troponin T and NKX2.5 mRNA is up-regulated in long-term cultured CAG-EGFP(high) rEBs, in which more than 90% of the cells become Troponin I positive mature CMs. Moreover, about one third of the CAG-EGFP(high) rEBs show spontaneous contractions. The method described here provides a powerful tool to generate expandable cultures of pure human CPCs that can be used for exploring early markers of the cardiac lineage, as well as for drug screening or tissue engineering applications.

    Toxic metal ions have been implicated in the generation of reactive oxygen species (ROS) and nitric oxide (NO). Metallothionines (MT) and plant flavonoids have been reported in the intervention against oxidative damage. We investigated the effect of zinc induced MT and green tea polyphenol (GTP) in reducing the oxidative responses induced by nickel and platinum. Methods Zinc (10 mg/kg b. wt, sc) was administered to rats twice at a gap of 24hrs and GTP (10 mg/100 mL in drinking water) was fed ad libitum for 8 days. Nickel chloride (150 umol/kgb.wt, ip) and cisplatin (50 (mol/kg b.wt, sc) was administered to rats 24 h after Zn or GTP pre-treatment. Animals of all the groups were sacrificed 16 hrs after treatment and biochemical markers for toxicity were monitored. Results Zinc or GTP pre-treatment caused significant protection against nickel or cisplatin enhanced mortality in rats, and reduction in lipid peroxidation and NO. Conclusion It is proposed that inhibition of ROS and NO by GTP and zinc may prove useful as a selective pharmacological agent in the amelioration of metal toxicity.

    Groups naturally promote their strengths and prefer values and rules that give them an identity and an advantage. This shows up as generational tensions across cohorts who share common experiences, including common elders. Dramatic cultural events in America since 1925 can help create an understanding of the differing value structures of the Silents, the Boomers, Gen Xers, and the Millennials. Differences in how these generations see motivation and values, fundamental reality, relations with others, and work are presented, as are some applications of these differences to the dental profession.

    Information communication Technology (ICT) has been a major influence in the Malaysian Education System, especially in the teaching of mathematics. Since 2003, the Malaysian Ministry of Education has provided incentives to mathematics teacher to motivate them to use ICT using English as the medium of instruction, during the teaching and learning process. However, there are barriers that prevented mathematics teachers from using ICT in the classrooms. This study is to determine factors that influenced the attitudes of Malaysian Mathematic Teachers in integrating ICT in their teaching and learning. One hundred ninety one mathematics teachers were randomly selected for the purpose of this study. The three factors investigated were school support, school facilities and school culture which had been selected to be correlated with teachers' attitudes towards integrating ICT in the teaching and learning of mathematics. Findings showed that significant positive relationships existed between teachers' attitudes toward integrating ICT in the teaching and learning and school support, school facilities and ICT culture and This finding indicated that, in order to develop teachers' attitudes in using ICT during their teaching and learning process, they needed support from the school principals and also their colleagues. Apart from that, school facilities and also ICT culture were also found to be essential.

    Modern ICT (Information and Communication Technology) has developed a vision where the "computer" is no longer associated with the concept of a single device or a network of devices, but rather the entirety of situated services originating in a digital world, which are perceived through the physical world. It is observed that services with explicit user input and output are becoming to be replaced by a computing landscape sensing the physical world via a huge variety of sensors, and controlling it via a plethora of actuators. The nature and appearance of computing devices is changing to be hidden in the fabric of everyday life, invisibly networked, and omnipresent, with applications greatly being based on the notions of context and knowledge. Interaction with such globe spanning, modern ICT systems will presumably be more implicit, at the periphery of human attention, rather than explicit, i.e. at the focus of human attention. Socio-inspired ICT assumes that future, globe scale ICT systems should be viewed as...

    Full Text Available Blockchain technology, while still challenged with key limitations, is a transformative Information and Communications Technology (ICT that has changed our notion of trust. Improved efficiencies for agricultural sustainable development has been demonstrated when ICT-enabled farms have access to knowledge banks and other digital resources. UN FAO-recommended ICT e-agricultural infrastructure components are a confluence of ICT and blockchain technology requirements. When ICT e-agricultural systems with blockchain infrastructure are immutable and distributed ledger systems for record management, baseline agricultural environmental data integrity is safeguarded for those who participate in transparent data management. This paper reviewed blockchain-based concepts associated with ICT-based technology. Moreover, a model ICT e-agriculture system with a blockchain infrastructure is proposed for use at the local and regional scale. To determine context specific technical and social requirements of blockchain technology for ICT e-agriculture systems, an evaluation tool is presented. The proposed system and tool can be evaluated and applied to further developments of e-agriculture systems.

    Full Text Available The National Israeli Information and Communication Technology (ICT Program that called for the “adaption of the educational system to the 21st century”, has been implemented in Israel since 2010. The program’s purpose intended to introduce an ‘ICT culture’ in the educational system – pre-schools and lower-level schools, as well as in higher education institutions, including teachers colleges. Following this call, the current study is aimed at examining the integration of ICT in a teaching training college in the north of Israel, in the context of a technological-pedagogic setting, the ICT culture in the college, and how educators’ metaphorical sensations contribute to their use of ICT tools and to student training in an ICT environment. The second aim of the research was to identify the operating factors in the course of educators’ professional development that impact on the integration of advanced technologies in teaching. This mixed-methods study involved 120 educators. Through structural equation modelling, the findings show that educators’ familiarity and mastery of ICT tools influence use for teaching purposes, more so than personal feelings, the ICT culture, and the availability of the tools. Findings emphasize the need for promoting the integration of technology in teachers colleges as a learning organization, from a systemic view, which emphasizes the teacher educator’s personal-professional development.

    The information and communication technology (ICT) is a key enabling technology for Smart Grids. With respect to very short innovation cycles for ICT compared to longer innovation cycles for the transition of the energy system there is a huge challenge to develop and exploit the potential of future ICT and their application in a future intelligent energy system. Different ICT technologies, such as Internet of Things or Cloud Computing are intensively being discussed. They can be summarized under the term ''Future Internet''. The EU project FINSENY is investigating the potential of Future Internet concepts and technologies in particular for Smart Energy systems. A series of design principles and the necessary ICT are developed, which are described in this paper. These design principles such as open interfaces, security-by-design, simplicity, maintenance, auto-configuration and modularity are of general nature. They will remain despite technology developments. Furthermore, several design principles are not only applicable to ICT but they are also related to design principles of intelligent energy systems like decentralized energy generation systems.

    Full Text Available Intuitive expertise in the application of advanced interdisciplinary facilitation is the subject of this personal reflection on the graduate supervisory style of Professor David Squires in computers in education. This single-case reflective study examines the characteristics of effective supervision observed during masters and doctoral supervision at King's College in the years 1990-9. Interdisciplinarity in ICT graduate studies particularly requires a fluency of supervisory expertise in enabling supervisees to combine multiple complex perspectives from a number of fields of knowledge. Intuitive combinatory aspects of supervision are highlighted in this reflection on the role carried out by an academic expert in facilitating student success. This is examined from a perspective incorporating affective as well as intellectual elements, informed by characteristics identified in professional sports and performing arts coaching/mentoring. Key characteristics comprising a model of intuitive expertise in ICT graduate supervision were outlined. The resultant portrait aims to complement existing literature on graduate supervision, with reference to the field of ICTI computers in education relating to student hypermedia composition.

    Ever-increasing needs and demands by dentists and all other members of the dental team for education and training at all levels - undergraduate, postgraduate and continuing - are straining the resources of existing providers of such education. At the same time, there are ever-increasing opportunities to develop online delivery and the use of a range of information and communication technology (ICT) systems and services further, in all aspects of dental education. This paper reviews recent developments that have led to an increased demand for dental postgraduate programmes and continuing professional development (CPD) courses in the United Kingdom and then discusses how ICT has and will impact on teaching practice. Examples include the use of teaching and learning resources in a virtual learning environment (VLE) and the increasing use of blended learning. The paper then explores the need for both teachers and students to adapt to the new environment to ensure they can benefit to the maximum and that teaching and learning practices are changed accordingly.

    2016-11-01

    Full Text Available Indonesian ELT is complex for numerous reasons, and the level of students‟ outcome has been regarded unsatisfactory by a number of researchers and academics. This paper considers ICT as one of possible alternatives to deal with the complexity of Indonesian ELT and to improve its outcomes. It widely explores ICT integration in English LTL, especially on how ICT has been used in this field. It further investigates the benefits and challenges of integrating ICT in LTL. The paper argues that the integration of ICT is promising for changing and improving the effectiveness of the current Indonesian ELT condition when it is carried out in line with the effective LTL principles. The integration of ICT will enable teachers to vary teaching and learning activities, to gradually change the teaching style to be more student-centred, to train students to have more active role in learning, and to access a huge range of authentic learning materials. The paper also acknowledges the contraints that will emerge in an effort of integrating ICT in Indonesian English LTL. Hence, some recommedations for action are proposed at the end.

    Full Text Available International literature and Norwegian policy documents both identify school leadership as essential in order to implement ICT (Information and Communication Technologies in teaching and learning practices in the classrooms. Data from an online survey in 2009 of 247 school leaders and 386 teachers from Norwegian primary and lower secondary schools are used to examine if conditions promoted by school leaders are associated with the use of ICT in classrooms by teachers. The research question posed in this paper is if the attitudes and behaviours of school leaders with regard to ICT in their schools correlate with the attitudes and behaviours of teachers? To answer the question, four construct variables are utilised as indicators of school leadership for ICT. These indicators are informative on school leaders’ decisions and beliefs regarding their schools as ICT-using organizations. Results showed that the indicators were correlated with the time teachers spend on ICT in the classrooms and for administrative use, their use of common digital tools and with a construct measuring the teachers’ attitudes towards innovative and student-centred pedagogy (life-long learning attitudes. The indicators of school leadership for ICT carry traits of perspectives from distributed, transformational and pedagogical leadership, but more research is needed in order to align the practice-based indicators with more overarching theoretical concepts.

    As the use of information and communication technology (ICT) becomes more widespread in dentistry the risk of breaching electronic commerce laws and patient confidentiality increases. It is necessary to be aware of the responsibilities internet usage entails, especially within a dental practice where the protection of patient information is of the utmost importance. More should be done to outline the various precautions that should be taken to ensure ICT security within the professional domain, as it would appear dentistry has been neglected with regard to receiving the proper ICT education, training and support systems.

    Full Text Available This essay describes some benefits of implementing ICT in classroom, especially within the area of collaborative and self-managed learning. However, implementing ICT in classroom is not an easy and simple matter. There are many issues which should be addressed. Those issues range from the school culture, teachers barriers, finance, leadership, curriculum, and ethical issues. Those problems are experienced by both developed and developing countries. This also refutes a widespread assumption that developing countries experience more barriers for implementing ICT than developed countries.

    Full Text Available We analyze the perception of the integration of ICT in higher education from beginning scholars. It uses a protocol and participant observation with collection of evidences in the form of educational products. Among the major findings we meet that teaching practice is traditional, teaching is perceived as a sum of techniques, processes of change that are experienced in European universities do not push them, have not reflect enough about teaching, and that ict is one element of their practice that has not the main role. It shows how traditional education negatively affects the possibilities of integration of ict and the methodology each teacher uses. It offers some recommendations for change.

    Full Text Available Over the past 25 years, social movements have actively sought out and used new information and communication technologies (ICT, such as the Internet and mobile phones, to give voice to their concerns. The growth of access and use of ICT in the Middle East and North Africa provided resources for protesters and governments to influence political and social events. The widespread availability of the Internet and mobile phones to facilitate organization and action raises the research question of how ICT affects protest movements.

    Full Text Available Ethics and Information Communication Technology (ICT Governance both have their place in today’s business organisations, but can their practical applications present an ethical ambiguity for the IT professional employed within the business organisation? The guidelines contained within various codes of ethics recommend principles regarding the ethical behaviour of individual IT professionals. In contrast, IT Governance as outlined in the new Australian Standard for Corporate Governance of Information and Communication Technology (ICT provides ICT governance advice for business. This paper explores the difference between these viewpoints.

    Full Text Available The purpose of this paper is to examine how ICT development is progressing and what kind of political and social effects have been occurring (or could occur in the near future in Middle Eastern Arabic countries. To examine this theme, this paper will adopt the Syrian Arab Republic as a case. To understand the Syrian government's policy toward the ICT development, it is necessary to examine the domestic political situation, since they are closely related. Under the Bashar Al- Asad's regime, we can confirm several reasons why they have to move forward on their ICT development policy and why it has become a crucial issue, which they cannot evade, as they had done under the previous regime, Hafez Al- Asad's regime. The situation that the Syrian government is facing right now is known by the term, "Dictator's Dilemma". This paper tries to provide bases in order to examine and explore this dilemma in Syria. Also, when we examine ICT development in Syria, it is important to consider the ICT support policies, which are mainly conducted by OECD countries and international organizations and stem from the issue of "Digital Divide". This is why international assistances could have great effect on ICT development in Syria. As a provisional conclusion of this paper, I will summarize how we can understand the current situation of ICT development in Syria, and I will also comment on the future prospect of the dilemma that the Syrian government is facing at the present time.

    The election platform of Ontario's new provincial Liberal government included a Renewable Portfolio Standard (RPS) which would provide approximately 2,700 MW of new renewable energy capacity in the province. Green power refers to power production that has a low impact on the environment, that is renewable, or both. Two drivers for green power would be government policy through RPSs or voluntary consumer purchase of somewhat more expensive green power. The long term goal is for green power to cost no more than power from conventional sources. There were 23 active green power programs in Ontario in 2002 in the following four categories: government policy, utility development, green power marketing, and green certificate marketing. In 2002 there was a total of 539 MW of green power generating capacity in Canada, representing 0.5 per cent of all power generated. Alberta had the largest contribution, producing 1.6 per cent of power from renewable resources. Ontario has at least 3,000 MW of wind power potential, and close to 500 MW of untapped small-hydro potential at decommissioned or undeveloped sites. Two hundred and sixty MW of electrical capacity could be generated from bio-digesters that would convert manure into methane gas and high-grade fertilizer. Hot water heating accounts for about 20 per cent of home energy usage. A solar hot water system could supply about 50 per cent of this energy. 3 tabs., 1 fig.
