  1. MATLAB-Based VHDL Development Environment

    Energy Technology Data Exchange (ETDEWEB)

    2002-01-01

    The Reconfigurable Computing program at Los Alamos National Laboratory (LANL) required synthesizable VHDL Fast Fourier Transform (FFT) designs that could be quickly implemented into FPGA-based high speed Digital Signal Processing architectures. Several different FFTs were needed for the different systems. As a result, the MATLAB-Based VHDL Development Environment was developed so that with a small amount of work and forethought, arbitrarily sized FFTs with different bit-width parameters could be produced quickly from one VHDL generating algorithm. The result is highly readable VHDL that can be modified quickly via the generating function to adapt to new algorithmic requirements. Several additional capabilities are integrated into the development environment. These capabilities include a bit-true parameterized mathematical model, fixed-point design validation, test vector generation, VHDL design verification, and chip resource use estimation. LANL needed the flexibility to build a wide variety of FFTs with a quick turn around time. It was important to have an effective way of trading off size, speed and precision. The FFTs also needed to be efficiently implemented into our existing FPGA-based architecture. Reconfigurable computing systems at LANL have been designed to accept two or four inputs on each clock. This allows the data processing rate to be reduced to a more manageable speed. This approach, however, limits us from using existing FFT cores. A MATLAB-Based VHDL Development Environment (MBVDE) was created in response to our FFT needs. MBVDE provides more flexibility than is available with VHDL. The technique allows new designs to be implemented and verified quickly. In addition, analysis tools are incorporated to evaluate trade-offs. MBVDE incorporates the performance of VHDL, the fast design time of core generation, and the benefit of not having to know VHDL available with C-tools into one environment. The MBVDE approach is not a comprehensive solution, but

  2. WAVES VHDL interface

    1994-06-01

    The Waveform and Vector Exchange Specification (WAVES) is the Industry standard representation for digital stimulus and response for both the design and test communities. The VHSIC Hardware Description Language (VHDL) is the Industry standard language for the design, modeling, and simulation of digital electronics. Together VHDL and WAVES provide powerful support for top-down design and test methodologies and concurrent engineering practices. Although the syntax of WAVES is a subset of VHDL, no special support for using WAVES in a VHDL environment is defined within the language. This report will introduce and describe a VHDL package that was developed at Rome Laboratory to provide a software interface to support the use of WAVES in a VHDL environment. This VHDL package is referred to as the WAVES VHDL interface and has been proposed as a standard practice for a top-down design and test methodology using WAVES and VHDL. This report is not intended to provide a tutorial on VHDL or WAVES. It is assumed that the reader has an adequate understanding of the VHDL language and some modeling techniques. Further, it is assumed that the reader has an understanding of the WAVES language and can follow a simple Level 1 dataset description.

  8. A VHDL-AMS package for microsystems polychromatic optical modeling

    Science.gov (United States)

    Quiquerez, Laurent; Ouaaziz, Siomar; Pittet, Patrick; Lu, Guo-Neng

    2004-08-01

    For biomedical microanalysis systems requiring implementation of optical signal generation and detection, we propose a package of VHDL-AMS functions to allow co-simulations of optical path, opto-electronic elements and associated electronics. This package contains a set of functions, which may be used for functional description of parts of microanalysis systems. An overview of simulation techniques shows that VHDL-AMS allows continuous-time simulation of polychromatic optical signals needed by the wavelength shifting nature of fluorescence. Indeed, directivity of optic path is well managed by VHDL-AMS using directional ports. By design, optical signals are easily simulated together with associated command and processing electronic circuits. Inspired by RF simulation techniques, the proposed description of polychromatic optical signals lies on a discretization of spectra. This format allows each optic band to be processed independently by models. The array data structure available in VHDL-AMS provides a compact form to device descriptions and to optical signal connexions. Fluorescence is modelled with absorbance and emission spectra, and optical couplings are described using results of geometric-optic analysis. A "spectral plug-in" has been developed, to be connected to output-power models of LASER-LED reported in the literature. Furthermore, a physical model of the CMOS Buried Double Junction (BDJ) detector has been described. Models of optic and electronic parts include a modulated LASER source, fibre optic, fluorochrom, BDJ detector and Constant Voltage Threshold (CVT) analogue-to-digital signal conversion. The system-level simulations, with Variable-Time Synchronous Detection (VTSD) are performed using the "Advanced-MS" environment. The validity domain of this approach as well as limitations of the available VHDL-AMS simulators (especially in terms of convergence and simulation time) are discussed.

  12. VHDL simulation of the implementation of a costfunction circuit

    1990-09-01

    Since VHDL is a DoD standard hardware description language, it is widely used in the design of logic circuits at different levels. VHDL can be used to do behavioral modeling which is desirable in top-down system design. A cost function calculation in a graph partition algorithm is used here as an example to test the VHDL design methodology. Subroutines or statements in the software can be implemented into hardware if the subroutines or the statements in that software are suitably grouped. While the design of hardware is considered, high density integration of circuit is also the primary goal. Parts of an old design were condensed using programmable EPLDs which were programmed by commercial software development tools. The methodology of implementation goes from a register transfer language description to data flow design and control flow design. The costfunction calculation was successfully put into 4 EP1800 chips and the design was simulated in VHDL. The primary goal of integration was achieved at the expense of speed. To support the total simulation several behavior models were created. Results of simulation revealed that the adder circuit in the EP1800 can be further improved. Experiences of using VHDL are discussed in this thesis.

  14. C/VHDL Codesign for LHCb VELO zero suppression algorithms

    CERN Document Server

    Muecke, Manfred

    2005-01-01

    We present a workflow to generate cycle-accurate C and VHDL code from one common description to accelerate and unify algorithm implementation and simulation for real-time DSP applications in particle detectors. We use Confluence as description language which compiles into C-code (for simulation) and VHDL code (for implementation on FPGAs). We demonstrate the improved portability and simulation speed while assuring bit- and cycle-accuracy. Our approach solves the problem of having to maintain two source codes (for simulation and implementation) in parallel and therefore minimizes workload and the danger of inconsistent models. This is crucial in an environment where algorithm implementation is expected to cycle through several design iterations.

    Nowadays, chaos generators are an attractive field for research and the challenge is their realization for the development of engineering applications. From more than three decades ago, chaotic oscillators have been designed using discrete electronic devices, very few with integrated circuit technology, and in this work we propose the use of field-programmable gate arrays (FPGAs) for fast prototyping. FPGA-based applications require that one be expert on programming with very-high-speed integrated circuits hardware description language (VHDL). In this manner, we detail the VHDL descriptions of chaos generators for fast prototyping from high-level programming using Python. The cases of study are three kinds of chaos generators based on piecewise-linear (PWL) functions that can be systematically augmented to generate even and odd number of scrolls. We introduce new algorithms for the VHDL description of PWL functions like saturated functions series, negative slopes and sawtooth. The generated VHDL-code is portable, reusable and open source to be synthesized in an FPGA. Finally, we show experimental results for observing 2, 10 and 30-scroll attractors.

    1998-12-01

    This paper discusses how we generate VHDL codes for DSP applications described in data flow graphs. Because the generated VHDL code implements the details of the control structure, we can easily transform it into a running circuit without any modifications, using logic synthesis tools. To improve the quality of the synthesized circuit we apply some graph transformation techniques to the original data flow graph. We mainly consider coarse-grained data flow graphs in which each node corresponds to an IP component of considerable size. The proposed facility is very useful for data flow graph based high level design tools, including our co design framework PeaCE (Ptolemy extension as Codesign Environment).

    2007-01-01

    Recent FPGA chips, with their large capacity memory and reconfigurability potential, have opened new frontiers for rapid prototyping of embedded systems. With the advent of high density FPGAs it is now feasible to implement a high-performance VLIW processor core in an FPGA. We describe research results of enabling the DSP TMS320 C6201 model for real-time image processing applications, by exploiting FPGA technology. The goals are, firstly, to keep the flexibility of DSP in order to shorten the development cycle, and secondly, to use powerful available resources on FPGA to a maximum in order to increase real-time performance. We present a modular DSP C6201 VHDL model which contains only the bare minimum number of instruction sets, or modules, necessary for each target application. This allows an optimal implementation on the FPGA. Some common algorithms of image processing were created and validated on an FPGA VirtexII-2000 multimedia board using the proposed application development cycle. Our results demonstrate that an algorithm can easily be, in an optimal manner, specified and then automatically converted to VHDL language and implemented on an FPGA device with system level software.

    2005-04-01

    Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

    Environmental problems and their impact on health and welfare of the population, mainly the most deprived and excluded, from access to material and symbolic goods, provided only to a privileged minority, must be analyzed within the context of the global economic and financial crisis which swept the whole world since 2008. The collapse of the capitalist system and its negative impacts on production, income and employment provide evidence to the predatory nature of the underlying social and political relations which lead humanity to a catastrophic abyss whose consequences are felt on local, national and global levels. Appointing to the main aspects of environmental deterioration - greenhouse gases; pollution of rivers, lakes and oceans; the erosion and intoxication of soils; the lack of basic sanitation and fresh water supply in metropolitan areas, this essay refers to official health indicators published recently by the Ministry of Health of Brazil which documents destructive trends. Discussing the dysfunction and the paradoxes of capital accumulation the essay points out to the need for building a new development paradigm based on cooperation and solidarity; an equitable distribution of the social product and the reform of the political system leading from the present authoritarian patterns of social relations to a participative and a true democratic model.

Even in the genesis itself, based on the information provided in the divine books and scientific researches and all the facts that surround us, it can be seen that firstly God created nature and then he put the man on the Earth. Hence, the environment is a dominant factor of human development. The world is heading towards a common trade which in the scientific literature is known as economic or commercial globalization, and Kosovo is headed in this direction. Kosovo has started its competitive business activity since 1999. The Kosovo business despite the legal restrictions factors, technical infrastructure and fiscal policy has shown a solid and promising development. Since the Republic of Kosovo is oriented towards market economy, business is a key factor for the economic development, the Interior Gross Product (GDP, job occupation as well as filling the state budget. The Kosovo business despite its development, it faces the unfavorable environment of normal and competitive development.

  2. Intellectual property protection (IPP) using obfuscation in C, VHDL, and Verilog coding

    Meyer-Bäse, Uwe; Castillo, Encarni; Botella, Guillermo; Parrilla, L.; García, Antonio

    2011-06-01

    One of the big challenges in the design of embedded systems today is how to combine design reuse and intellectual property protection (IPP). Strong IP schemes such as hardware dongle or layout watermarking usually have a very limited design reuse for different FPGA/ASIC design platforms. Some techniques also do not fit well with protection of software in embedded microprocessors. Another approach to IPP that allows an easy design reuse and has low costs but a somehow reduced security is code "obfuscation." Obfuscation is a method to hide the design concept, or program algorithm included in the C or HDL source by using one or more transformations of the original code. Obfuscation methods include, for instance, renaming identifiers, removing comments or formatting of the code. More sophisticated obfuscation methods include data splitting or merging, and control flow changes. This paper shows strength and weakness of method obfuscating C, VHDL and Verilog code.

    Sandia National Laboratories has been developing technologies to support person-to-person collaboration and the efforts of teams in the business and research communities. The technologies developed include knowledge-based design advisors, knowledge management systems, and streamlined manufacturing supply chains. These collaborative environments in which people can work together sharing information and knowledge have required a new approach to software development. The approach includes an emphasis on the requisite change in business practice that often inhibits user acceptance of collaborative technology. Leveraging the experience from this work, they have established a multidisciplinary approach for developing collaborative software environments. They call this approach ``A Holistic Software Development Methodology''.

    Full Text Available The introduction of inter-school electronic networks has added a new dimension to education in Canada that has many implications for students who attend schools in rural communities. Collaborative internet-based teaching and learning and the creation of virtual classes within regional intranets now complement traditional on-site instruction in many schools that are located beyond major centres of population. Five stages in the advent of virtual educational environments can be identified starting with the introduction of computers in schools as a foundation for the development of collaborative teaching and learning environments. Inter-school collaboration in rural Canada and the extension of curriculum options for senior students has, in turn, provided a basis for the integration of virtual classes and traditional face to face instruction. Instruction in classes that are electronically-linked to other classes requires different skills from traditional face to face teaching and the development of new strategies and protocols. The implications of open and flexible teaching and learning for the future organization of classes, the preparation of teachers, articulation with higher education and in particular, regional economic development are now significant educational policy issues. The linking of virtual and face to face classes through cybercells is a possible next step in the development of virtual educational environments.

    2014-11-01

    Full Text Available When we were invited by the editors of Sustainability to put together a special edition on “Environment in Sustainable Development” our first reaction was to question whether this was really needed. After all, the environment has long been regarded as a central plank in sustainability and there are countless articles and books published on an annual basis that explore the impact of our economic and social activities on our environment. Just what is it that a special edition can achieve? What new angles could we hope to provide? Our initial thinking was to link the special edition to a particular, almost unique, location in time rather than space. We are in the process of recovering, albeit stuttering, from the deepest economic crash experienced by the European and North American economies. The crash has brought some national economies to their knees and, if economic commentators are to be believed, almost destroyed the Euro. Recovery from that crash has been slow and it is arguable whether at the time of writing this has developed much momentum. There is still the skewed perception that prosperity equals economic growth and that economic growth can take place without real (sustainable development or by simply implementing austerity measures and surely without people’s participation. An analogy from National Parks worldwide is when conservation agencies try to enforce protection without local people’s support. All such attempts have either failed or resurrected only once people’s involvement was secured and guaranteed. The unidirectional austerity measures imposed mainly in the countries of southern Europe have destroyed social cohesion leaving deeply wounded societies, while at the same time have also put up for grabs important assets (including natural capital in each of these countries and therefore in jeopardy even their long term recovery.

    The Software Developer's Assistant (SDA) helps software teams more efficiently and accurately conduct or execute software processes associated with NASA mission-critical software. SDA is a process enactment platform that guides software teams through project-specific standards, processes, and procedures. Software projects are decomposed into all of their required process steps or tasks, and each task is assigned to project personnel. SDA orchestrates the performance of work required to complete all process tasks in the correct sequence. The software then notifies team members when they may begin work on their assigned tasks and provides the tools, instructions, reference materials, and supportive artifacts that allow users to compliantly perform the work. A combination of technology components captures and enacts any software process use to support the software lifecycle. It creates an adaptive workflow environment that can be modified as needed. SDA achieves software process automation through a Business Process Management (BPM) approach to managing the software lifecycle for mission-critical projects. It contains five main parts: TieFlow (workflow engine), Business Rules (rules to alter process flow), Common Repository (storage for project artifacts, versions, history, schedules, etc.), SOA (interface to allow internal, GFE, or COTS tools integration), and the Web Portal Interface (collaborative web environment

  16. Insect Development in Altered Gravitational Environment

    Tischler, Marc E.

    1996-01-01

    When tobacco hornworm (Manduca sexta) larvae burrow underground (25-30 cm) to pupate, they reorient themselves to a relatively horizontal position indicating an ability to sense gravity. To evaluate their sensitivity to gravitational environment during metamorphosis, Manduca (pharate adults) were placed in a vertical (head-up) position. Distinct morphological changes, each one reflecting ensuing phases, were used to follow adult development. Five days after pupation, the vertical group showed accelerated (P less than 0.05) development and were nearly 4 phases ahead (P less than 0.0001) after 10 days. Differences in development in the vertical group were characterized further by increased (7-48%) hemolymph concentrations of 13 amino acids, but a decrease in cys and pro and no change in arg, his, met and val (trp, undetectable). Decreased (36%) turnover of injected H-3 - phenylalanine suggested slower utilization of amino acids contributed, at least partly, to the increased concentrations. Vertically-oriented Manduca also exhibited a greater (20 %, P less than 0.001) protein content in their flight muscles near the end of development. Analysis of hemolymph sugar levels showed a redistribution of sugars from the monosaccharide glucose to the disaccharide trehalose. Since injection of 20-hydroxyecdysone decreased (49%) turnover of H-3- phenylalanine in pharate adults and since ecdysteroids are known to increase flight muscle size and control adult development, these results are consistent with our measuring a greater (+80%, P less than 0.05) ecdysteroid titer in the vertically-oriented insects. These results suggest that gravity environment influences ecdysone output by the pharate adult. When we evaluated hemolymph flow in the head-up and control positions, we found that injected C-14-inulin was distributed somewhat more rapidly in the head-up group irrespective of the sight of injection (head or abdomen) likely because in the head-up position flow of the hemolymph is

    One remaining barrier to the clinical acceptance of electronic imaging and information systems is the difficulty in providing intuitive access to the information needed for a specific clinical task (such as reaching a diagnosis or tracking clinical progress). The purpose of this research was to create a development environment that enables the design and implementation of advanced digital imaging workstations. We used formal data and process modeling to identify the diagnostic and quantitative data that radiologists use and the tasks that they typically perform to make clinical decisions. We studied a diverse range of radiology applications, including diagnostic neuroradiology in an academic medical center, pediatric radiology in a children's hospital, screening mammography in a breast cancer center, and thoracic radiology consultation for an oncology clinic. We used object- oriented analysis to develop software toolkits that enable a programmer to rapidly implement applications that closely match clinical tasks. The toolkits support browsing patient information, integrating patient images and reports, manipulating images, and making quantitative measurements on images. Collectively, we refer to these toolkits as the UCLA Digital ViewBox toolkit (ViewBox/Tk). We used the ViewBox/Tk to rapidly prototype and develop a number of diverse medical imaging applications. Our task-based toolkit approach enabled rapid and iterative prototyping of workstations that matched clinical tasks. The toolkit functionality and performance provided a 'hands-on' feeling for manipulating images, and for accessing textual information and reports. The toolkits directly support a new concept for protocol based-reading of diagnostic studies. The design supports the implementation of network-based application services (e.g., prefetching, workflow management, and post-processing) that will facilitate the development of future clinical applications.

    1998-09-01

    This article is based on "Salud, ambiente y desarrollo humano sostenible: el caso de México," a document prepared in June 1997 by the Comité Técnico Nacional para el Desarrollo Sostenible. It opens with information regarding the epidemiologic and demographic changes that have taken place in Mexico, such as the decrease in communicable diseases, the rise in noncommunicable diseases, and the less conspicuous increase in lesions resulting from accidents or acts of violence. This is followed by a discussion of priority problems and problems of lesser magnitude in environmental health, specifically those relating to water and air quality, as well as disposal of household and dangerous wastes. Finally, it proposes three areas of intervention in light of the structural problems detected: the absence of an integrated information system covering the area of health, environment, and development; the absence of channels of communication within and between institutions and sectors, and the lack of coordination in planning and implementing programs and actions in this field.

  1. Resources, environment and economic development in Nigeria.

    Okpala, A O

    1995-06-01

    It is argued that Nigeria must focus on effective environmentally protective intensive farming, resource management methods, and strong family planning programs. Other contributory factors are recognized as the lack of democracy and the "ill-advised" internal policies of the government. The emphasis is on man-made decisions about migration, natality, and land use practices that have ecological consequences that significantly affect the economy. Land degradation in Nigeria is attributed to improper agricultural and husbandry practices. Land degradation has severe ecological, economic, and human costs. Awareness of environmental problems in Nigeria is growing. Natural disasters such as the droughts of 1984-85, continued soil depletion, accumulations of soil wastes, increased flooding in urban areas, and land erosion in Anambra state are evidence of the growing environmental problems. Agricultural development should involve changing rural land use practices, using technology that is "appropriate" to the climate, crops, and culture of the people, and introducing agroforestry. Population growth in Nigeria puts pressure on the fragile ecosystem. Actual carrying capacity is a rough calculation. Nigeria's population growth patterns follow a pattern that suggests population pressure on carrying capacity. The acceleration of population growth has strained the traditional system of agriculture. Land is overused, and cultivation continues on unsuitable land. Domestic policies during the oil boom encouraged rapid industrialization at the expense of the environment. Migration increased to urban centers, but cities did not provide suitable housing, waste disposal, safe water supplies, and other basic facilities.

    Given the significance of monitoring the critical environmental factors that facilitate athlete performance, this two-phase research aimed to validate and refine the revised talent development environment questionnaire (TDEQ). The TDEQ is a multidimensional self-report scale that assesses talented athletes' environmental experiences. Study 1 (the first phase) involved the examination of the revised TDEQ through an exploratory factor analysis (n = 363). This exploratory investigation identified a 28-item five-factor structure (i.e., TDEQ-5) with adequate internal consistency. Study 2 (the second phase) examined the factorial structure of the TDEQ-5, including convergent validity, discriminant validity, and group invariance (i.e., gender and sports type). The second phase was carried out with 496 talented athletes through the application of confirmatory factor analyses and multigroup invariance tests. The results supported the convergent validity, discriminant validity, and group invariance of the TDEQ-5. In conclusion, the TDEQ-5 with 25 items appears to be a reliable and valid scale for use in talent development environments.

    Bhutan's energy and environmental situation and approaches to development are reviewed and analyzed in this paper. Conservation of natural resources and human happiness have been placed as central strategic policy themes and have been given high priority in the national development plans of Bhutan. Bhutan's unique approach to development via Gross National Happiness (GNH) or the Middle Path of development is being facilitated by the Royal Government of Bhutan as a tool to balance poverty alleviation, environmental conservation and development. However, challenges exist due to the constraints of resources, good governance, legal frameworks, and human capacity. This paper reviews selected sustainable energy projects (e.g. energy from renewables or energy conservation) in Bhutan and finds that in fact, Bhutan's renewable energy resources (e.g. water and forests) which have proved to be indispensable for development are vulnerable due to the adverse impacts of climate change and environmental degradation. Appropriate measures in order to reduce potential environmental degradation and mitigate climate change impacts have been acknowledged globally and these have potential for application in Bhutan. For example, implementation of sustainable energy projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol could offer an opportunity for mitigating climate change impacts and also contributing to sustainable development.

  12. Rapid-X - An FPGA Development Toolset Using a Custom Simulink Library for MTCA.4 Modules

    Prędki, Paweł; Heuer, Michael; Butkowski, Łukasz; Przygoda, Konrad; Schlarb, Holger; Napieralski, Andrzej

    2015-06-01

    The recent introduction of advanced hardware architectures such as the Micro Telecommunications Computing Architecture (MTCA) caused a change in the approach to implementation of control schemes in many fields. The development has been moving away from traditional programming languages ( C/C++), to hardware description languages (VHDL, Verilog), which are used in FPGA development. With MATLAB/Simulink it is possible to describe complex systems with block diagrams and simulate their behavior. Those diagrams are then used by the HDL experts to implement exactly the required functionality in hardware. Both the porting of existing applications and adaptation of new ones require a lot of development time from them. To solve this, Xilinx System Generator, a toolbox for MATLAB/Simulink, allows rapid prototyping of those block diagrams using hardware modelling. It is still up to the firmware developer to merge this structure with the hardware-dependent HDL project. This prevents the application engineer from quickly verifying the proposed schemes in real hardware. The framework described in this article overcomes these challenges, offering a hardware-independent library of components that can be used in Simulink/System Generator models. The components are subsequently translated into VHDL entities and integrated with a pre-prepared VHDL project template. Furthermore, the entire implementation process is run in the background, giving the user an almost one-click path from control scheme modelling and simulation to bit-file generation. This approach allows the application engineers to quickly develop new schemes and test them in real hardware environment. The applications may range from simple data logging or signal generation ones to very advanced controllers. Taking advantage of the Simulink simulation capabilities and user-friendly hardware implementation routines, the framework significantly decreases the development time of FPGA-based applications.

    Full Text Available Rapid economic growth and irrational use of natural resources in the last decades of the XX century have influenced the changes in the environmental sphere and to specific environmental problems. These processes in the global economy and society, caused a disturbance of the environment by increasing pollution of the environment. Emerging problems of the entire human society can be solved by applying the concept of sustainable growth and development and raising awareness about the necessity of implementation of basic environmental standards in business. In order to reduce the harmful effects of production processes on the environment and to help meet the objective of sustainable development outlined at the UN Conference on Environment and Development in Rio De Janeiro in 1992 the ISO 14000 Standards were created. The essence of sustainable development is responsible development that meets the current needs a way to rationally use natural resources to ensure meeting the needs of future generations and environment protection.

    Knowledge Base (KB) is an essential component for capturing, structuring and defining the meanings of domain knowledge. It’s important in enabling the sharing and interoperability of scientific data and services in a smart manner. It’s also the foundation for most the research in semantic field, such as semantic reasoning and ranking. In collaborating with ESIP, GMU is developing an online interface and supporting infrastructure to allow semantic registration of datasets and other web resources. The semantic description of data, services, and scientific content will be collected and transformed to the KB. As a case study, the harvest of web map services from by Nordic mapping agencies to build a virtual Arctic spatial data infrastructure will be used as the domain example. To automate the process, a controlled vocabulary of certain subjects, such as solid water, is created to filter from existing data and service repositories to obtain a collection of closely related document. Then latent semantic indexing is utilized to analyze semantic relationship among concepts that appears in service document. At last, semantic structure in plain text will be mapped and automatically populated to the specific presentation of knowledge in the KB.

    Full Text Available The paper explores the concept of vocational educational environment combining vocational training, professional development and professional world. The research is aimed at the self-determination analysis of an individual in the above environment. The authors observe the two existing trends of self-development analysis, corresponding with the subjective activity and culturally historical approaches. The empirical research results involve the students’ subjective individual characteristics and factors influencing the self-development strategy selection. The research findings prove the earlier hypothesis of the self- development phenomenon being determined by the two mutually conditioned factors: personal self-control ability and interrelation of the above mentioned components of the vocational educational environment. The authors make the conclusion that the self-development prospects are determined by the internal and external motivation, professional mobility and striving for success. The determination specificity of professional self- development, identified by the authors, can provide the psychological basis for future specialists training.

    To assess the association between quality of stimulation in the family environment and child's cognitive development considering the impact of mother's schooling on the quality of stimulation. A cross-sectional study comprising 350 children aged 17-42 months was carried out in central and peripheral areas of Salvador, Northeastern Brazil, in 1999. A socio-economic questionnaire was used, along with the Home Observation for Measurement of the Environment Scale (HOME Inventory), and the Bayley Scale for Infant Development. Bivariate and multivariate analyses were carried out through linear regression at 5% level of significance. There was a positive (beta=0.66) and statistically significant association between quality of stimulation in the family environment and child's cognitive development. Part of the effect was mediated by the mother's working circumstances and educational level. It was verified that a better quality of stimulation is provided for those who come early in the birth order in family, and live with only a few others under five years of age. This pattern of stimulation is better among children who live with their parents and whose mothers have better education, have a job and a partner involved in the family environment. Quality of stimulation in the family environment is crucial for child's cognitive development, besides the significant role of the available resources and family dynamics. The study findings show the pertinence to cognitive development of interventions which improve the quality of the environment and the child-caregiver relationship.

    Full Text Available In the past few years, excessive efforts have been made to increase the city’s attractiveness and its international positioning. Also studies on the so-called city destination branding are on the rise. Theorists, as Ramirez (2001, Marzano and Scott (2009, among many others, are discussing different aspects of this complex process. Many approaches and strategies are dealing with the positioning of urban environments and city destinations, trying to provide at least some partial answers about achieving this objective. With proper marketing and branding, cities can do a lot to attract tourists and visitors. For successful city marketing and branding and for the successful long-term positioning of the destination in general, it is necessary to involve the key stakeholders and collaborate with as many as possible despite the fact that the branding of a city destination (or any destination for that matter is a complex process. It is significant that all the stakeholders, who are always carriers of different interests, are invited to collaborate in the planning of the tourism development and tourism development strategies, from the government, the private sector, schools etc. It is also important to involve the citizens, who can provide a valuable opinion about the environment they live in – what they like about their environment, what suggestion would they give to tourists about gastronomy, attractions, shops, events, etc. It is significant that citizens are proud of their urban environment, that they know their own environment, and that they have the motivation for the involvement in the process of improvement of their home environment (through projects, discussions, etc.. It is impossible to create attractive urban environments or cities if residents do not have a positive opinion about the place they live in.

    The Joint Space Operations Center (JSpOC) Mission System (JMS) is the program of record tasked with replacing the legacy Space Defense Operations Center (SPADOC) and Astrodynamics Support Workstation (ASW) capabilities by the end of FY2015 as well as providing additional Space Situational Awareness (SSA) and Command and Control (C2) capabilities post-FY2015. To meet the legacy replacement goal, the JMS program is maturing a government Service Oriented Architecture (SOA) infrastructure that supports the integration of mission applications while acquiring mature industry and government mission applications. Future capabilities required by the JSpOC after 2015 will require development of new applications and procedures as well as the exploitation of new SSA data sources. To support the post FY2015 efforts, the JMS program is partnering with the Air Force Research Laboratory (AFRL) to build a JMS application development environment. The purpose of this environment is to: 1) empower the research & development community, through access to relevant tools and data, to accelerate technology development, 2) allow the JMS program to communicate user capability priorities and requirements to the developer community, 3) provide the JMS program with access to state-of-the-art research, development, and computing capabilities, and 4) support market research efforts by identifying outstanding performers that are available to shepherd into the formal transition process. The application development environment will consist of both unclassified and classified environments that can be accessed over common networks (including the Internet) to provide software developers, scientists, and engineers everything they need (e.g., building block JMS services, modeling and simulation tools, relevant test scenarios, documentation, data sources, user priorities/requirements, and SOA integration tools) to develop and test mission applications. The developed applications will be exercised in these

    2015-07-01

    Objective, observational measures of nutrition environments are now well established and widely used. Individuals' perceptions of their nutrition environments may be equally or more important, but are less well conceptualized, and comprehensive measures are not available. This paper describes the development of the Perceived Nutrition Environment Measures Survey (NEMS-P), its test-retest reliability, and its ability to discern differences between lower- and higher-SES neighborhoods. This research involved five steps: (1) development of a conceptual model and inventory of items; (2) expert review; (3) pilot testing and cognitive interviews; (4) revising the survey; and (5) administering the revised survey to participants in neighborhoods of high and low SES on two occasions to evaluate neighborhood differences and test-retest reliability. Data were collected in 2010 and 2011 and analyzed in 2011 and 2012. The final survey has 118 items. Fifty-three core items represent three types of perceived nutrition environments: community nutrition environment, consumer nutrition environment, and home food environment. Test-retest reliability for core constructs of perceived nutrition environments was moderate to good (0.52-0.83) for most measured constructs. Residents of higher-SES neighborhoods reported higher availability scores in stores, stronger agreement that healthy options were available in nearby restaurants, and higher scores for accessibility of healthy foods in their homes. The NEMS-P has moderate to good test-retest reliability and can discriminate perceptions of nutrition environments between residents of higher- and lower-SES neighborhoods. This survey is available and ready to be used. Copyright © 2015 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

    2015-01-01

    The Classroom Sensory Environment Assessment (CSEA) is a tool that provides a means of understanding the impact of a classroom's sensory environment on student behavior. The purpose of the CSEA is to promote collaboration between occupational therapists and elementary education teachers. In particular, students with autism spectrum disorder included in general education classrooms may benefit from a suitable match created through this collaborative process between the sensory environment and their unique sensory preferences. The development of the CSEA has occurred in multiple stages over 2 yr. This article reports on descriptive results for 152 classrooms and initial reliability results. Descriptive information suggests that classrooms are environments with an enormous variety of sensory experiences that can be quantified. Visual experiences are most frequent. The tool has adequate internal consistency but requires further investigation of interrater reliability and validity. Copyright © 2015 by the American Occupational Therapy Association, Inc.

    Given the rapid pace of urbanization and Westernization and the increasing prevalence of obesity, there is a need for research to better understand the influence of the built environment on overweight and obesity in world's developing regions. Culturally-specific food environment survey instruments are important tools for studying changing food availability and pricing. Here, we present findings from an effort to develop and evaluate food environment survey instruments for use in a rapidly developing city in southwest China. We developed two survey instruments (for stores and restaurants), each designed to be completed within 10 minutes. Two pairs of researchers surveyed a pre-selected 1-km stretch of street in each of three socio-demographically different neighborhoods to assess inter-rater reliability. Construct validity was assessed by comparing the food environments of the neighborhoods to cross-sectional height and weight data obtained on 575 adolescents in the corresponding regions of the city. 273 food establishments (163 restaurants and 110 stores) were surveyed. Sit-down, take-out, and fast food restaurants accounted for 40%, 21% and 19% of all restaurants surveyed. Tobacco and alcohol shops, convenience stores and supermarkets accounted for 25%, 12% and 11%, respectively, of all stores surveyed. We found a high percentage of agreement between teams (>75%) for all categorical variables with moderate kappa scores (0.4-0.6), and no statistically significant differences between teams for any of the continuous variables. More developed inner city neighborhoods had a higher number of fast food restaurants and convenience stores than surrounding neighborhoods. Adolescents who lived in the more developed inner neighborhoods also had a higher percentage of overweight, indicating well-founded construct validity. Depending on the cutoff used, 19% to 36% of male and 10% to 22% of female 16-year old adolescents were found to be overweight. The prevalence of

    An arc-heater driven hyperthermal convective environments simulator was recently developed and commissioned for long duration hot hydrogen exposure of nuclear thermal rocket materials. This newly established non-nuclear testing capability uses a high-power, multi-gas, wall-stabilized constricted arc-heater to produce hightemperature pressurized hydrogen flows representative of nuclear reactor core environments, excepting radiation effects, and is intended to serve as a low-cost facility for supporting non-nuclear developmental testing of hightemperature fissile fuels and structural materials. The resulting reactor environments simulator represents a valuable addition to the available inventory of non-nuclear test facilities and is uniquely capable of investigating and characterizing candidate fuel/structural materials, improving associated processing/fabrication techniques, and simulating reactor thermal hydraulics. This paper summarizes facility design and engineering development efforts and reports baseline operational characteristics as determined from a series of performance mapping and long duration capability demonstration tests. Potential follow-on developmental strategies are also suggested in view of the technical and policy challenges ahead. Keywords: Nuclear Rocket Engine, Reactor Environments, Non-Nuclear Testing, Fissile Fuel Development.

    With the booming in the manufacturing sector of shoe, garments and toy, etc. in pearl region, training the usage of various facilities and design the facility layout become crucial for the success of industry companies. There is evidence that the use of virtual training may provide benefits in improving the effect of learning and reducing risk in the physical work environment. This paper proposed an advanced web-based training environment that could demonstrate the usage of a CNC machine in terms of working condition and parameters selection. The developed virtual environment could provide training at junior level and advanced level. Junior level training is to explain machining knowledge including safety factors, machine parameters (ex. material, speed, feed rate). Advanced level training enables interactive programming of NG coding and effect simulation. Operation sequence was used to assist the user to choose the appropriate machining condition. Several case studies were also carried out with animation of milling and turning operations.

    Full Text Available Abstract Background Route environments can be a potentially important factor in influencing people's behaviours in relation to active commuting. To better understand these possible relationships, assessments of route environments are needed. We therefore developed a scale; the Active Commuting Route Environment Scale (ACRES, for the assessment of bicyclists' and pedestrians' perceptions of their commuting route environments. Here we will report on the development and the results of validity and reliability assessments thereof. Methods Active commuters (n = 54 were recruited when they bicycled in Stockholm, Sweden. Traffic planning and environmental experts from the Municipality of Stockholm were assembled to form an expert panel (n = 24. The active commuters responded to the scale on two occasions, and the expert panel responded to it once. To test criterion-related validity, differences in ratings of the inner urban and suburban environments of Greater Stockholm were compared between the experts and the commuters. Furthermore, four items were compared with existing objective measures. Test-retest reproducibility was assessed with three types of analysis: order effect, typical error and intraclass correlation. Results There was a concordance in sizes and directions of differences in ratings of inner urban and suburban environments between the experts and the commuters. Furthermore, both groups' ratings were in line with existing objectively measured differences between the two environmental settings. Order effects between test and retest were observed in 6 of 36 items. The typical errors ranged from 0.93 to 2.54, and the intraclass correlation coefficients ranged from 'moderate' (0.42 to 'almost perfect' (0.87. Conclusions The ACRES was characterized by considerable criterion-related validity and reasonable test-retest reproducibility.

    Full Text Available Experts estimate that physical deterioration of the planet and environment, they stress more serious. The destruction of forests is accelerating and the deserts are extending. Soil erosion undermines not only agricultural production but also winning means needed of existence for millions of people, while gradual disappearance of species of plants and animals diminishes our heritage biological. For the first time in history the structure atmosphere land is modifying by the destruction of the ozone layer which protects us from ultraviolet radiations, it is causing accumulation of greenhouse gases, which leads inevitably to warming climate Earth. Today is widely accepted the concept of sustainable development. It was defined the World Conference on Environment and Development in 1987, as a development that would ensure the present needs without jeopardizing the future generations capacity to satisfy its own requirements. The governments, including the Romanian, have started to react when devastating environmental changes have become ever more obvious. However, the discrepancy between what should be done to protect the capacity of planet to ensure living conditions and that what was achieved in practice is on the rise. In our country the phenomenon of environment degradation with all the concern displayed and the financial effort accomplished, obviously insufficient, tends to magnify, especially in the last period as a result of intensification of polluant industrial activity. In this sense, any cost cannot be considered too big, for the protection of life as a last resort.

    2016-11-01

    Full Text Available The article explores the complex relationships between the natural environment , tourist transport and sustainable tourism development. In order to research the impact of natural resources on tourism activity, on the one hand, and the influences of tourism on the environment, on the other hand, statistical and mathematical methods of analysis and forecast were used, namely, the analysis of the dynamics of significant indicators of the natural environment and of tourist activity, the correlation method, the Markov chains method. The analyses made lead us to the conclusion of the existence of a positive evolution of significant indicators of the natural environment, with an impact on tourist activity, such as natural parks. It has been emphasized; also, that this positive evolution has a direct influence on the attraction of visitors, specifically, foreign ones, but the intensity of this influence is average. The intensification of the actions of promotion of natural parks and, generally, of protected areas in Romania, would be a direction for attracting an increased number of visitors, with all the favourable economic consequences. On the other hand, the research has outlined the fact that, as far as the means of transportation used by tourists to visit Romania are concerned, on the first places we can see road and air transport, means of transportation which, aside from the obvious advantages for tourists, have a strong negative impact on the environment. The forecast made with the help of the Markov chains method has shown a negative trend, from the point of view of the impact on the environment, namely an increase in the share of road and air transport in the preference of foreign visitors to Romania. The current research represents a contribution to the efforts of measuring, through statistical and mathematical models, of the complex influences, in both senses, between the environment and tourist activity. Thus, an objective radiography has

    2003-01-01

    The requirements development process for the Advanced Engineering Environment (AEE) is presented. This environment has been developed to allow NASA to perform independent analysis and design of space transportation architectures and technologies. Given the highly collaborative and distributed nature of AEE, a variety of organizations are involved in the development, operations and management of the system. Furthermore, there are additional organizations involved representing external customers and stakeholders. Thorough coordination and effective communication is essential to translate desired expectations of the system into requirements. Functional, verifiable requirements for this (and indeed any) system are necessary to fulfill several roles. Requirements serve as a contractual tool, configuration management tool, and as an engineering tool, sometimes simultaneously. The role of requirements as an engineering tool is particularly important because a stable set of requirements for a system provides a common framework of system scope and characterization among team members. Furthermore, the requirements provide the basis for checking completion of system elements and form the basis for system verification. Requirements are at the core of systems engineering. The AEE Project has undertaken a thorough process to translate the desires and expectations of external customers and stakeholders into functional system-level requirements that are captured with sufficient rigor to allow development planning, resource allocation and system-level design, development, implementation and verification. These requirements are maintained in an integrated, relational database that provides traceability to governing Program requirements and also to verification methods and subsystem-level requirements.

    2015-08-01

    Kindergarten education in Hong Kong serves children aged 32-68 months. However, there is no extant scale that measures kindergarten teachers' perceived work environment, an important influence on their well-being. To develop a new instrument, the Teachers' Perceived Work Environment (TPWE) scale, and to assess whether kindergarten teachers with higher TPWE ratings had higher scores for job satisfaction, self-esteem and mental health. A 25-item rating scale was developed and used with a sample of in-service kindergarten teachers. Their perceived work environment was represented by five factors (ergonomics, staffing, teaching space, work hours and social space). These teachers also completed three well-being inventories: the Job Satisfaction Survey, the Rosenberg Self-Esteem Inventory and the General Health Questionnaire-12. In a second stage, a new sample of in-service kindergarten teachers was used to cross-validate the findings from the earlier assessment. In the first sample of 141 teachers and the second of 125, social space, staffing and work hours were associated with job satisfaction, while ergonomics was a significant negative predictor of mental health complaints. The TPWE exhibited satisfactory reliability and validity. Some factors were differentially associated with specific types of well-being. The results may inform future studies of the working conditions of kindergarten teachers. © The Author 2015. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

    The environment sustainable development and biota protection, including the environment radiation protection are issues of nowadays interest in the society. An activity is ongoing on the development of a system of radiation protection for non-human biota. Anthropocentric and eco-centric principles are widely discussed. ICRP Publications 103, 108, 114 and many other reports and articles refer to the topic of environmental protection, reference animals and plants set, corresponding transfer parameters, dose models and derived consideration reference levels. There is still an open field for discussion of methods and approaches to get well-established procedure to assess environmental risks of radiation impacts to different organisms, populations and ecosystems. A huge work has been done by the ICRP and other organizations and research groups to develop and systematize approaches for this difficult subject. This activity, however, is not everywhere well-known and perceived, and more efforts are needed to bring ideas of eco-centric strategy in the environment radiation protection not only to public but to specialists in many countries as well. One of the main points of interest is an assessment of critical doses and doses rates for flora and fauna species. Some aspects of a possible procedure to find their estimates are studied in this work, including criteria for datasets of good quality, models of dose dependence, sensitivity of different umbrella endpoints and methods of original massive datasets treatment. Estimates are done based on information gathered in a database on radiation-induced effects in plants. Data on biological effects in plants (umbrella endpoints of reproductive potential, survival, morbidity, morphological, biochemical, and genetic effects) in dependence on dose and dose rates of ionizing radiation have been collected from reviewed publications and maintained in MS Access format. The database now contains about 7000 datasets and 25000 records

    2013-04-01

    Full Text Available Most software development projects rely on Integrated Development Environments (IDEs based on the desktop paradigm, with an interactive, mouse-driven user interface. The standard installation of ACL2, on the other hand, is designed to work closely with Emacs. ACL2 experts, on the whole, like this mode of operation, but students and other new programmers who have learned to program with desktop IDEs often react negatively to the process of adapting to an unfamiliar form of interaction. This paper discusses Proof Pad, a new IDE for ACL2. Proof Pad is not the only attempt to provide ACL2 IDEs catering to students and beginning programmers. The ACL2 Sedan and DrACuLa systems arose from similar motivations. Proof Pad builds on the work of those systems, while also taking into account the unique workflow of the ACL2 theorem proving system. The design of Proof Pad incorporated user feedback from the outset, and that process continued through all stages of development. Feedback took the form of direct observation of users interacting with the IDE as well as questionnaires completed by users of Proof Pad and other ACL2 IDEs. The result is a streamlined interface and fast, responsive system that supports using ACL2 as a programming language and a theorem proving system. Proof Pad also provides a property-based testing environment with random data generation and automated interpretation of properties as ACL2 theorem definitions.

  14. Expert Group Meeting on Population, Environment and Development.

    1993-01-01

    As part of the preparation for the up-coming International Conference on Population and Development, an expert group met at UN headquarters on January 20-24, 1992. The group noted that the momentum of population growth was expected to add 3 billion people to the global population between 1985 and 2025, with more than 90% of the growth occurring in the developing countries which are least able to respond to the attendant resource and environmental demands. The expert group discussed the interaction of population and resources, specifically the impact of population growth on the environment and carrying capacity. The meeting then focused on environmental discontinuities and uncertainties and on environmental degradation, specifically the loss of agricultural land, the destruction of tropical forests, fresh-water resource, the loss of biological diversify, and climate change. Following their deliberations, the expert group drafted 18 recommendations addressed to governments, social institutions, and international organizations. The group urged that governments establish or strengthen the integration of environmental and population concerns into development policy-making and planning and support technologies to achieve sustained economic growth and development while striving to replace the use of fossil fuels with renewable resources. Areas of the environment subject to acute population pressure should be identified and policies devised to reduce that pressure. Ecologically helpful labor-intensive projects should be implemented for their dual benefits. Women should be included in these activities, and their status in society, therefore, should be improved through improved education and participatory opportunities. The uses of water should be optimized to acknowledge its scarcity. The delivery of service to alleviate poverty should proceed in a manner that invites community participation, which, along with education, will be vital to institute these changes. Adequate

    2008-01-01

    The Radiation Hardened Electronics for Space Environments (RHESE) project consists of a series of tasks designed to develop and mature a broad spectrum of radiation hardened and low temperature electronics technologies. Three approaches are being taken to address radiation hardening: improved material hardness, design techniques to improve radiation tolerance, and software methods to improve radiation tolerance. Within these approaches various technology products are being addressed including Field Programmable Gate Arrays (FPGA), Field Programmable Analog Arrays (FPAA), MEMS, Serial Processors, Reconfigurable Processors, and Parallel Processors. In addition to radiation hardening, low temperature extremes are addressed with a focus on material and design approaches. System level applications for the RHESE technology products are discussed.

    2004-03-01

    The work reported in this document involves a development effort to provide combat commanders and systems engineers with a capability to explore and optimize system concepts that include operational concepts as part of the design effort. An infrastructure and analytic framework has been designed and partially developed that meets a gap in systems engineering design for combat related complex systems. The system consists of three major components: The first component consists of a design environment that permits the combat commander to perform 'what-if' types of analyses in which parts of a course of action (COA) can be automated by generic system constructs. The second component consists of suites of optimization tools designed to integrate into the analytical architecture to explore the massive design space of an integrated design and operational space. These optimization tools have been selected for their utility in requirements development and operational concept development. The third component involves the design of a modeling paradigm for the complex system that takes advantage of functional definitions and the coupled state space representations, generic measures of effectiveness and performance, and a number of modeling constructs to maximize the efficiency of computer simulations. The system architecture has been developed to allow for a future extension in which the operational concept development aspects can be performed in a co-evolutionary process to ensure the most robust designs may be gleaned from the design space(s).

    The Heat shield for Extreme Entry Environment Technology (HEEET) Project is a NASA STMD and SMD co-funded effort. The goal is to develop and mission infuse a new ablative Thermal Protection System that can withstand extreme entry. It is targeted to support NASAs high priority missions, as defined in the latest decadal survey, to destinations such as Venus and Saturn in-situ robotic science missions. Entry into these planetary atmospheres results in extreme heating. The entry peak heat-flux and associated pressure are estimated to be between one and two orders of magnitude higher than those experienced by Mars Science Laboratory or Lunar return missions. In the recent New Frontiers community announcement NASA has indicated that it is considering providing an increase to the PI managed mission cost (PIMMC) for investigations utilizing the Heat Shield for Extreme Entry Environment Technology (HEEET) and in addition, NASA is considering limiting the risk assessment to only their accommodation on the spacecraft and the mission environment. The HEEET ablative TPS utilizes 3D weaving technology to manufacture a dual layer material architecture. The 3-D weaving allows for flat panels to be woven. The dual layer consists of a top layer designed to withstand the extreme external environment while the inner or insulating layer by design, is designed to achieve low thermal conductivity, and it keeps the heat from conducting towards the structure underneath. Both arc jet testing combined with material properties have been used to develop thermal response models that allows for comparison of performance with heritage carbon phenolic. A 50 mass efficiency is achieved by the dual layer construct compared to carbon phenolic for a broad range of missions both to Saturn and Venus. The 3-D woven flat preforms are molded to achieve the shape as they are compliant and then resin infusion with curing forms a rigid panels. These panels are then bonded on to the aeroshell structure.

    Full Text Available The entertainment robotics have been on a peak with AIBO, but this robot brand has been discontinued by the Sony in 2006 to help its financial position. Among other reasons, the robot failed to enter into both the mainstream and the robotics research labs besides the RoboCup competitions, however, there were some attempts to use the robot for rehabilitation and emotional medical treatments. A native software development environment (Open-R SDK was provided to program AIBO, nevertheless, the operating system (Aperios induced difficulties for the students and the researchers in the software development. The author of this paper made efforts to update the Open-R and overcome the problems. More enhancements have been implemented in the core components, some software methodologies were applied to solve a number of restrictions and the achievements are summarized here.

  2. Development of a Simulated Environment for Human-Robot Interaction

    2011-12-01

    Full Text Available Human-robot interaction scenarios are extremely complicated and require precise definition of the environment variables for rigorously testing different aspects of robotic behavior. The environmental setup affects the behaviors of both the humans and the robots, as they respond differently under varying accoustic or lightning conditions. Moreover, conducting several experiments repeatedly with the humans as test subjects also causes behavioral changes in them and eventually the responses remain no longer similar to the already conducted experiments. Thus making it is impossible to perform interaction scenarios in a repeatable manner. Developing and using 3D simulations, where different parameters can be adjusted, is the most beneficial solution in such cases. This requires not only the development of different simulated robots but also the simulation of dynamic surroundings including the interaction partner. In this paper, we present a simulation framework that allows the simulation of human-robot interaction including the simulated interaction partner and its dynamics.

    Full Text Available Enterprise and Entrepreneurship are naturally connected and linked to the man, his individuality and dynamism. A man develops his entrepreneurial skills in the company is organized so that it represents a healthy environment for the development ambitions. The only reliable sources of progress and prosperity are the work and entrepreneurship. It has long been in the world economic literature of special importance in the process of restructuring the economy in economic growth and development of countries in transition is given to the establishment of new enterprises and entrepreneurship development. I do not believe that it is a new form of paradigm, however, the fact remains that a large shift in the literature devoted to the economy of transition. Entrepreneurship means a special kind of work which aims to emphasize the great importance of possessing human creative, organizational and management capacity. The term enterprise wants to emphasize the importance of possessing an exceptional human creative ability. It appears as a combination of dynamic development of ideas, talent, capital, knowledge and risk.

    1991-01-01

    The PRIST-2 system has been designed as an interactive and high-productivity tool for the rapid prototyping and development of medical applications. Three major issues were addressed in this research project which derived from the evolution of a previous 4th generation software package, called PRIST (patient record information system tool): a high transportability on different hardware and operating systems, a conversational and interactive user-interface and user-independence Relational Data Base Management System (RDBMS). Although we developed PRIST-2 on the top of the ORACLE RDBMS, it does not depend on SQL commercial products because the ORACLE features have been directly used only for SQL relational data base management. The application design methodology implemented in the system architecture allows an interactive and formal description of the application constraints in terms of the semantic data model rather than in terms of the data structure. The translation of the conceptual constraints into SQL tables is performed by several pre-defined routines. In the PC based release (MS/DOS, OS/2, Xenix operating systems), the Graphic-User Interface (GUI) has been developed using Microsoft Windows Software Development Kit. The UNIX release will use a GUI developed on top of the X-Windows environment.

  6. A Literary Perspective on the Environment: Rethinking Development through Art

    Directory of Open Access Journals (Sweden)

    Davi Silva Gonçalves

    2014-04-01

    Full Text Available Due to the environmental crisis that chokes contemporaneity, it is of paramount importance for society to rethink our physical and abstract behaviours towards nature. Ecocriticism, providing a bridge between literature and nature, allows us to reorganise proven problematic notions, such as progress and development, which tend to gradually separate human beings from the space they occupy. Such separation results in a detachment that hinders our ability to transcend metropolitan, narrow-minded, biased judgments regarding the future of developing countries like Brazil, and perhaps artistic tools like literature are the only ones capable of broadening our reflections for inviting us to go beyond preconditioned perspectives. This article aims at showing how Milton Hatoum’s novel The Brothers (2000 implies that we must look for distinct possibilities of developing our spaces, more specifically the Amazon, and, through the analysis of the book as well as the impact of development on the region, the dialogue between literature and nature is proposed. First the theoretical approach on both nature and literature is delineated, followed by a discussion on how important it is to (reconnect subjects and environment, and then by analysing the novel’s characters which evince the side effects of “progress” and “growth” in the Amazonian region. The result is a problematisation of normative dichotomies such as savage/civilised, past/future, subject/space, underdeveloped/developed, and the conclusion that, for development to stop being detrimental to nature, we shall avoid believing in a “faceless environment” (Campbell, 18, that is, one needs to start observing the impact of such development on the lives of those inevitably and automatically marginalised by it.

    The significant oil discoveries made at the end of the 90's in the deep water environment offshore the coast of Angola, has led to a considerable amount of development activities. The first field in production was the turnkey development of the Kuito field on the Block 14 operated by Chevron. More recently the Girassol field has been put successfully in production on the Block 17, operated by TotalFinaElf. Both developments are making use of sub-sea wells connected to a moored dedicated FPSO. On the western side of the Girassol field, several discoveries have been made. They are known as the Rosa Lirio pole, from the names of two of the main channels. Values for water depth are in the same range than on Girassol (1300- 1400 m). A project group has been established in 1999 to evaluate the development of these discoveries. The purpose of this paper is to present the conceptual work which as been carried out, and in particular to show that even if many different concepts have been evaluated, the final choice has been also to make use of sub-sea trees.

    The objective of this study was to develop a short and reliable Family Dynamic Environment Scale (FDES) that would better serve the needs of mental health professionals in detecting the potential for delinquent behavior in Korean adolescents related to a dysfunctional family dynamic environment. Semi-structured interviews with 30 adolescents were initially conducted to generate a set of items, after which, 44 participants were included in method test-retest reliability test. Finally, 544 participants recruited by proportional stratified random sampling were included in a factor analysis. The original version of the FDES had 60 items in 7 categories; the final version included 42 items grouped into 5 factors. Both test-retest reliability and Cronbach's alpha coefficient were high for the final version of the scale. As a result of factor analysis, five factors were extracted: family psychological climate, parent-child relationship, paternal parenting attitude, family cohesion, and maternal parenting attitude. These contributed 50.3% of the variance in the item scores. All 42 items loaded above .35 on their respective factors. The Cronbach's alpha coefficients for internal consistency were .95 for the total 42 items and .92, .81, .82, .78, and .71, respectively, for each of the 5 factors.

    Full Text Available This article analyzes the phenomenon of judicialization of environmental public policies, from the "lens" judicial activism, making sure that we can include the existence of this phenomenon in the treatment of these policies. In our post-modern era we have seen increasingly the role of the judiciary. Thus, it sought to address this issue of judicial activism against such contemporary issues as the environment, seeking to understand how the judiciary behaves in relation to environmental issues, which no longer has time to waive or give up the protection of natural resources and compliance with the principle of sustainable development. The methodology used was a literature review and secondary data collection. It was noticed a different activism in the face of environmental issues.

    The fluxes of energetic particles in the radiation belts are found to be strongly controlled by the solar wind conditions. In order to understand and predict the radiation particle intensities, we have developed a physics-based Radiation Belt Environment (RBE) model that considers the influences from the solar wind, ring current and plasmasphere. Recently, an improved calculation of wave-particle interactions has been incorporated. In particular, the model now includes cross diffusion in energy and pitch-angle. We find that the exclusion of cross diffusion could cause significant overestimation of electron flux enhancement during storm recovery. The RBE model is also connected to MHD fields so that the response of the radiation belts to fast variations in the global magnetosphere can be studied.Weare able to reproduce the rapid flux increase during a substorm dipolarization on 4 September 2008. The timing is much shorter than the time scale of wave associated acceleration.

    A unit level, Ada software module testing system, called Query Utility Environment for Software Testing of Ada (QUEST/Ada), is described. The project calls for the design and development of a prototype system. QUEST/Ada design began with a definition of the overall system structure and a description of component dependencies. The project team was divided into three groups to resolve the preliminary designs of the parser/scanner: the test data generator, and the test coverage analyzer. The Phase 1 report is a working document from which the system documentation will evolve. It provides history, a guide to report sections, a literature review, the definition of the system structure and high level interfaces, descriptions of the prototype scope, the three major components, and the plan for the remainder of the project. The appendices include specifications, statistics, two papers derived from the current research, a preliminary users' manual, and the proposal and work plan for Phase 2.

    2015-04-01

    Here we present an adaptation of global interacting hazard matrices for the purpose of improving disaster risk reduction in multi-hazard environments of Guatemala. Guatemala is associated with multiple natural hazards, including volcanic eruptions, earthquakes, mass movements and floods. These processes are often not independent and it is therefore important to consider and understand the ways by which they interact to generate cascades or networks of natural hazard events. We first present a review of such hazard interactions and hazard chains in Guatemala, focusing on the volcanic environments around Pacaya, Fuego and Santiaguito. Interactions discussed are those where a primary hazard triggers or increases the probability of secondary hazards. Consideration is also given to interactions where two hazards combine to trigger a third hazard, or two concurring hazards result in impacts greater than the sum of components. Second, we utilise and adapt global interacting hazard matrices designed to understand and communicate information about interactions. We explore the use of this hazard visualisation framework within the more regional Guatemalan context. Twenty-one semi-structured interviews, and a workshop with 16 participants, were held with hazard and civil protection professionals in Guatemala to solicit feedback on: (i) how visualisations with a global focus can be modified for use in Guatemala, (ii) possible end users for such visualisations, and (iii) participants' understanding of hazard interactions and their opinion of community understanding of these themes. Core ideas that emerged from these interviews were (i) the importance of such tools in rapid response, preparedness and community education, (ii) the appropriate scales for visualisation development, in order to have maximum impact, and (iii) the need to integrate anthropic factors to fully understand hazard cascades. It is hoped that the development of improved tools to understand natural hazard

    Visual Physics Analysis (VISPA) is a web-based development environment addressing high energy and astroparticle physics. It covers the entire analysis spectrum from the design and validation phase to the execution of analyses and the visualization of results. VISPA provides a graphical steering of the analysis flow, which consists of self-written, re-usable Python and C++ modules for more demanding tasks. All common operating systems are supported since a standard internet browser is the only software requirement for users. Even access via mobile and touch-compatible devices is possible. In this contribution, we present the most recent developments of our web application concerning technical, state-of-the-art approaches as well as practical experiences. One of the key features is the use of workspaces, i.e. user-configurable connections to remote machines supplying resources and local file access. Thereby, workspaces enable the management of data, computing resources (e.g. remote clusters or computing grids), and additional software either centralized or individually. We further report on the results of an application with more than 100 third-year students using VISPA for their regular particle physics exercises during the winter term 2012/13. Besides the ambition to support and simplify the development cycle of physics analyses, new use cases such as fast, location-independent status queries, the validation of results, and the ability to share analyses within worldwide collaborations with a single click become conceivable.

    2004-01-01

    Research and development (R&D) organizations are being required to be relevant, to be more application-oriented, and to be partners in the strategic management of the business while meeting the same challenges as the rest of the organization, namely: (1) reduced time to market; (2) reduced cost; (3) improved quality; (4) increased reliability; and (5) increased focus on customer needs. Recent advances in computer technology and the Internet have created a new paradigm of collaborative engineering or collaborative product development (CPD), from which new types of relationships among researchers and their partners have emerged. Research into the applicability and benefits of CPD in a low/no production, R&D, and/or government environment is limited. In addition, the supply chain management (SCM) aspects of these relationships have not been studied. This paper presents research conducted at the NASA Glenn Research Center (GRC) investigating the applicability of CPD and SCM in an R&D organization. The study concentrates on the management and implementation of space research activities at GRC. Results indicate that although the organization is engaged in collaborative relationships that incorporate aspects of SCM, a number of areas, such as development of trust and information sharing merit special attention.

    Full Text Available This article examines psychological predictors of inhibition in educational environments as well as various aspects of pedagogical communication, including facilitation, which is aimed at enhancing educational effectiveness and developing students by means of using a particular communication style and the teacher’s personality. The need to study inhibition (the deterioration of teacher-children interactions; the negation of a student’s individuality; the inability to understand and accept students’ viewpoints; teacher-provoked conflicts; and emotional callousness is substantiated. The essence of psychological predictors as independent variables, changes in which lead to changes in other dependent variables, allowing the prediction of inhibition development, is explained. The research objective was to identify psychological predictors of the development of inhibition in pedagogical communication. An empirical study was conducted using standardized techniques for diagnosing communicative attitudes (V. Boyko, developing general communicative tolerance (V. Boyko, identifying aggressiveness (A. Asinger, identifying the level of empathy (V. Boyko, and identifying the degree of pedagogical inhibition (L. Polosova. The sample contained 375 teachers from Yekaterinburg educational institutions, with participant selection made using stratified sampling. The teacher’s personality features (a negative communicative attitude, low communicative tolerance and empathy, and higher levels of aggression were shown to be key predictors of inhibition, which itself was found to depend on the length of teaching experience. At the beginning of one’s professional teaching career, the level of inhibition is minimal. However, the level of inhibition reaches its maximum level after 5-10 years of teaching, and after 20 years, there is a sharp decrease in the level of inhibition. The conclusion of this study stresses the importance of developing strategies to

    Full Text Available Integrated Project Delivery is a rapidly developing approach to Design and Construction.This approach uses business structures, new technologies, and newly developing practices to collaboratively utilise the talents and contributions of all participants in the Design and Construction process.This project replicated this approach by creating a collaborative project between the School of Construction and the School of Real Estate and Construction Economics. The term “collaborative learning” refers to a method of delivery in which students at various performance levels work together in small groups towards a common goal. The students were responsible for one another’s learning as well as their own. There were a number of objectives of this collaborative project. Promoting interaction between students from different but related courses, was at the centre of the study. Allied to this was the need to enhance student’s ability to think creatively, solve problems, and make decisions as a team. Additionally, it was important to evaluate the benefits of using a Virtual Learning Environment for teaching, learning and assessment and examine the benefits of Building Information Modelling (BIM as a tool for feedback. This study used a qualitative methodology, using focus group interviews, reflective journals, and individual interviews to gather data. The study included sixty students from the two schools in question, who were divided into groups of four. The students worked together on a common project, collaborating to achieve a common goal. There were a number of benefits to this project with an emphasis given to the interaction of the students. The collaborative learning approach provided a format for the students to interact, including: giving and receiving help; exchanging information and resources; giving and receiving feedback; challenging and encouraging each other; and jointly reflecting on progress. The other main benefit was in the use of a

    The harmonious development in society, economy and environment are crucial to regional sustained boom. However, the society, economy and environment are not respectively independent, but both mutually promotes one which, or restrict mutually complex to have the long-enduring overall process. The present study is an attempt to investigate the relationship and interaction of society, economy and environment in China based on the data from 2004 to 2013. The principal component analysis (PCA) model was employed to identify the main factors effecting the society, economy and environment subsystems, and SD (system dynamics) method used to carry out dynamic assessment for future state of sustainability from society, economy and environment perspective with future indicator values. Sustainable development in China was divided in the study into three phase from 2004 to 2013 based competitive values of these three subsystems. According to the results of PCA model, China is in third phase, and the economy growth is faster than the environment development, while the social development still maintained a steady and rapid growth, implying that the next step for sustainable development in China should focus on society development, especially the environment development.

  2. Essays on energy, equity, and the environment in developing countries

    Science.gov (United States)

    Israel, Debra Kim

    1999-11-01

    The essays in this dissertation explore different environmental and public policy issues relevant to developing countries. Essay I examines household-level survey responses to the question "How willing would you be to pay somewhat higher taxes to the government if you knew the money would be spent to protect the environment and prevent land, water and air pollution?" Specifically, for twelve developing and three developed countries included in the survey, the empirical relationships among willingness to pay for environmental quality, relative household income and national income are investigated. The results indicate that when the effects of household and national income are combined, households with below-average income in low-income countries are less willing to pay for environmental protection than those with above-average income in high-income countries. Furthermore, willingness to pay for environmental protection increases more significantly with relative household income than with national income. Essay II uses data from urban Bolivia to study the determinants of household fuel choice, an important link between deforestation and indoor air pollution in developing countries. In particular, the effects of fixed fuel costs, income growth, and female earned income on household fuel choice are examined. The results imply that reduction in firewood use in developing countries is not likely to occur simply as the result of income growth. The essay discusses possible policy implications based on the results that fixed fuel costs appear to be a deterrent to switching to a cleaner fuel and households with female earned income seem less likely to use firewood than other households. Essay III analyzes the equity implications of the elimination of fuel subsidies in the 1985 Bolivian economic reforms. An analysis of the direct static burden shows that while the elimination of gasoline subsidies was progressively distributed, the elimination of LPG and kerosene subsidies

    In the 1990s ecological early warning research began with the aim of elucidating the effect of drought in dry regions of the world. Drought has been a prevalent natural disaster, ravaging the Yun'nan province of China for over 5 years since 2009. Due to the extensive range, depth and devastating losses, the drought has reached a once-in-a-century severity. Yun'nan province suffered particularly badly from the drought, which took its toll on both the ecological environment and the sustainable economic development of the province. We chose to study Pu'er city in Yun'nun province for this research, and analysed the drought traits of Pu'er city utilizing geographic information technology. We applied the Mann-Kendall test for trend, linear tendency estimation and percentage of precipitation anomalies, as well as using combinations of monthly data searches of meteorological reports from 1980-2010. The results showed that except for a small rise in spring precipitation, the overall rainfall of Pu'er city showed a decreasing trend. The results of this study can provide an adequate and reliable theoretical basis and technological methods for use in government decision making, and promote research into early warning ecology.

    Background Investigation of the environmental influences on human behavioral phenotypes is important for our understanding of the causation of psychiatric disorders. However, there are complexities associated with the assessment of environmental influences on behavior. Methods/Principal Findings We conducted a series of analyses using a prospective, longitudinal study of a nationally representative birth cohort from Finland (the Northern Finland 1966 Birth Cohort). Participants included a total of 3,761 male and female cohort members who were living in Finland at the age of 16 years and who had complete temperament scores. Our initial analyses (Wessman et al., in press) provide evidence in support of four stable and robust temperament clusters. Using these temperament clusters, as well as independent temperament dimensions for comparison, we conducted a data-driven analysis to assess the influence of a broad set of life course measures, assessed pre-natally, in infancy, and during adolescence, on adult temperament. Results Measures of early environment, neurobehavioral development, and adolescent behavior significantly predict adult temperament, classified by both cluster membership and temperament dimensions. Specifically, our results suggest that a relatively consistent set of life course measures are associated with adult temperament profiles, including maternal education, characteristics of the family’s location and residence, adolescent academic performance, and adolescent smoking. Conclusions Our finding that a consistent set of life course measures predict temperament clusters indicate that these clusters represent distinct developmental temperament trajectories and that information about a subset of life course measures has implications for adult health outcomes.

    The following research is operated as a Laboratory Directed Research and Development (LDRD) initiative at Sandia National Laboratories. The long-term goals of the program include sophisticated diagnostics of advanced fuels testing for nuclear reactors for the Department of Energy (DOE) Gen IV program, with the future capability to provide real-time measurement of strain in fuel rod cladding during operation in situ at any research or power reactor in the United States. By quantifying the stress and strain in fuel rods, it is possible to significantly improve fuel rod design, and consequently, to improve the performance and lifetime of the cladding. During the past year of this program, two sets of experiments were performed: small-scale tests to ensure reliability of the gages, and reactor pulse experiments involving the most viable samples in the Annulated Core Research Reactor (ACRR), located onsite at Sandia. Strain measurement techniques that can provide useful data in the extreme environment of a nuclear reactor core are needed to characterize nuclear fuel rods. This report documents the progression of solutions to this issue that were explored for feasibility in FY12 at Sandia National Laboratories, Albuquerque, NM.

  6. Immune development and environment: lessons from Amish and Hutterite children.

    Children who grow up in traditional farm environments are protected from developing asthma and allergy. This 'farm effect' can be largely explained by the child's early life contact with farm animals, in particular cows, and their microbes. Our studies in Amish and Hutterite school children living on farms in the U.S. have further demonstrated that this protection is mediated through innate immune pathways. Although very similar with respect to ancestry and many lifestyle factors that are associated with asthma risk, Amish and Hutterites follow farming practices that are associated with profound differences in the levels of house dust endotoxin, in the prevalence of asthma and atopy among school children, and in the proportions, phenotypes, and functions of immune cells from these children. In this review, we will consider our studies in Amish and Hutterites children in the context of the many previous studies in European farm children and discuss how these studies have advanced our understanding of the asthma-protective 'farm effect'.

  7. Consumption in relation to population, environment and development.

    Science.gov (United States)

    Myers, N

    1997-01-01

    Consumption is defined as the total spending on goods, investments, and services that changes materials and energy and reduces availability of natural resources for the future. The rich consume on a grand scale, but marginal consumption by large numbers of poor people can also deplete nonrenewable resources. This article discusses the complex relationships between consumption and population and between these two factors and environment and development. Consumption of natural resources since the mid-1900s has surpassed consumption prior to that time. The richest 20% of the global population have doubled their per capita consumption of energy, meat, timber, steel, and copper and have quadrupled the number of cars owned since 1950. The poorest 20% barely increased their per capita consumption. 40% of the total world population accounts for 6.5% of the world's income. The US, with under 5% of world population, consumes about 30% of the resources. The US standard of consumption is the desired ideal in many countries, but this standard is not justified. A low projected global population of 6 billion population would increase consumption by 8.4 times. Food and energy examples are used to illustrate the resource impact. Policy must move toward sustainable consumption and meet needs differently, develop environmentally friendly goods and services, and change the nature and extent of consumption. Policy must internalize externalities, eliminate perverse subsidies, calculate the ecological impact, promote efficiency and sufficiency, mobilize the media, and set "best practices" examples. Science also has responsibilities. The future rests with decisions about how to design a better system or a default option until failures in ecological and social systems appear. Life styles should emphasize nonmaterial satisfactions. The ratio of poor to rich is 60:1, which is unacceptable. Rich citizens will eventually need to pay the price of a change in their philosophies.

    It is generally agreed that the governmental authorities should actively encourage the development of an efficient framework of information and communication technology initiatives so as to advance and promote sustainable development and planning strategies. This paper presents a prototype Information System for public administration which was designed to facilitate public management and decision making for sustainable development and planning. The system was developed by using several programming languages and programming tools and also a Database Management System (DBMS) for storing and managing urban data of many kinds. Furthermore, geographic information systems were incorporated into the system in order to make possible to the authorities to deal with issues of spatial nature such as spatial planning. The developed system provides a technology based management of geospatial information, environmental and crime data of urban environment aiming at improving public decision making and also at contributing to a more efficient sustainable development and planning.

    2010-08-01

    Full Text Available Novice programmers generally have difficulty learning to program and one of the problems contributing towards this is the program development environment used at tertiary institutions. A number of pedagogical program development environments have been developed specifically for novice programmers, but these have not been compared experimentally with professional program development environments. A study was conducted that compared the perceptions of novice programmers using a representative professional program development environment to a pedagogical program development environment during an Introductory Programming module at a tertiary institution. It was found that the use of a pedagogical program development environment had a positive effect on the feelings of achievement and learning while learning to program, while the perceived ease of using the program development environment and the perceived difficulty of practical assignments were not affected.

    Directory of Open Access Journals (Sweden)

    Kevin Fuchs

    2016-06-01

    Full Text Available In this paper we introduce an approach for the creation of adaptive learning environments that give human-like recommendations to a learner in the form of a virtual tutor. We use ontologies defining pedagogical, didactic and learner-specific data describing a learner's progress, learning history, capabilities and the learner's current state within the learning environment. Learning recommendations are based on a reasoning process on these ontologies and can be provided in real-time. The ontologies may describe learning content from any domain of knowledge. Furthermore, we describe an approach to store learning histories as spatio-temporal trajectories and to correlate them with influencing didactic factors. We show how such analysis of spatiotemporal data can be used for learning analytics to improve future adaptive learning environments.

    2009-09-01

    This study examines the effect of family environment on language performance in children with myelomeningocele compared with age- and education-matched controls selected from the same geographic region. Seventy-five monolingual (English) speaking children with myelomeningocele [males: 30; ages: 7-16 years; mean age: 10 years 1 month, standard deviation (SD) 2 years 7 months] and 35 typically developing children (males: 16; ages 7-16 years; mean age: 10 years 9 months, SD 2 years 6 months) participated in the study. The Comprehensive Assessment of Spoken Language (CASL) and the Wechsler tests of intelligence were administered individually to all participants. The CASL measures four subsystems: lexical, syntactic, supralinguistic and pragmatic. Parents completed the Family Environment Scale (FES) questionnaire and provided background demographic information. Standard independent sample t-tests, chi-squared and Fisher's exact tests were used to make simple comparisons between groups for age, socio-economic status, gender and ethnicity. Spearman correlation coefficients were used to detect associations between language and FES data. Group differences for the language and FES scores were analysed with a multivariate analysis of variance at a P-value of 0.05. For the myelomeningocele group, both Spearman correlation and partial correlation analyses revealed statistically significant positive relationships for the FES 'intellectual-cultural orientation' (ICO) variable and language performance in all subsystems (P family environment appears statistically and intuitively sound. As in our previous study, the positive link between family focus on intellectually and culturally enhancing activities and language performance among children with myelomeningocele and shunted hydrocephalus remains robust. Knowledge of this relationship should assist parents and professionals in supporting language development through activities within the natural learning environment.

    Full Text Available The paper presents an approach to evaluation the impact of the level of development of institutional environment on the success of the reforms of public administration. The indicators that characterize the degree of development of the institutional environment, in particular, the level of protection of property rights, the development of political competition, civil society, corruption, and trust in society are shown. Depending on the elements of the political-administrative system, socio-economic features, that determine the trajectories of reforms, showing alternative purposes and characterized some indicators, that characterizing the results of reforms for the OECD-counties. Showing institutional problems is implementing reforms in the transition countries, depending on the elements of the political and administrative systems, and socio-cultural factors that determine the path of reform, showing alternative purposes and characterized by individual indicators characterizing the results of the OECD reform. From the point of view of the classification results, the emphasis is made on quantitative results of the operational type, in particular, the dynamics of the general government expenditure and the level of employment of civil servants in relation to employment in the economy as a whole. Showing institutional problems in the implementation of reforms in the transition countries, in particular the gap of development of the bureaucratic ethos, the weakness of the market environment and the insufficient level of external pressure on the quality of public services. The significance for the success of reform and systemic cultural change within the state apparatus, which affects the quality of citizens' satisfaction with public services is observed. It is noted that the preliminary formalization of the public sector, the formation of Weberian bureaucracy type is essential for successful implementation of the New Public Management.

    2010-01-01

    Full Text Available Abstract This paper presents a word length selection method for the implementation of digital controllers in both fixed-point and floating-point hardware on FPGAs. This method uses the new types defined in the VHDL-2008 fixed-point and floating-point packages. These packages allow customizing the word length of fixed and floating point representations and shorten the design cycle simplifying the design of arithmetic operations. The method performs bit-true simulations in order to determine the word length to represent the constant coefficients and the internal signals of the digital controller while maintaining the control system specifications. A mixed-signal simulation tool is used to simulate the closed loop system as a whole in order to analyze the impact of the quantization effects and loop delays on the control system performance. The method is applied to implement a digital controller for a switching power converter. The digital circuit is implemented on an FPGA, and the simulations are experimentally verified.

    Sensor data fusion is the combination of two or more information streams. We describe a sensor that fuses sonar and visual data to create a three dimensional(3D) model of the environment. A laser slit beam from laser source is slitted by a set of cylindrical lenses and the line image of the slit beam on the object is used to estimate the object parameters. Surface modeling routine and transferring the resulting surfaces to a IGRIP via a standard graphic software. The results suggest that the information of the multisensor system is significant compared to each sensor acting alone and this performance of this environmental modeling scheme would be suitable for reconstruction of data.

    Full Text Available The emergence, formation, and development of the city are largely connected with its landscape position. The first stage of Samarkand’s existence may be referred to as “river civilization.” Over the course of development of the city, the nature and intensity of interaction of the population and economy with its landscape have undergone changes; there is a distinct general pattern: dependence on the landscape. This was largely the reason for its sustainable development for many centuries. This fact should be considered in future activities in landscape and spatial planning.

    Pradbre, J-P

    2014-12-01

    This study examines the prospects for strong growth in the supply and demand for animal products worldwide, especially in developing countries, where 80% of the world's population lives. Based on scientific publications, statistics and field observations, it reviews greenhouse gas emission levels from livestock, the ability of ruminant livestock systems to sequester carbon and the capacity of the livestock industry to meet the challenge of sustainable development and to share its benefits while minimising impacts to climate change. Special attention is paid to the situation of the 800 million livestock farmers in the world living at the extreme end of poverty. The study underlines the importance of improving livestock productivity and the interdependence of the economic, environmental and social components of sustainable development. It highlights how, in the least developed countries and most lower-middle-income countries, the pressure exerted by animal diseases hampers efforts to improve livestock productivity. Poor livestock farmers have not sufficiently benefited from development policies and need support to adopt technological advances to meet the challenges of sustainable development and poverty reduction.

    Kumar, V.; German, Marjorie D.; Lee, S.-J.

    1989-01-01

    An overview is given of a design optimization project that is in progress at the GE Research and Development Center for the past few years. The objective of this project is to develop a methodology and a software system for design automation and optimization of structural/mechanical components and systems. The effort focuses on research and development issues and also on optimization applications that can be related to real-life industrial design problems. The overall technical approach is based on integration of numerical optimization techniques, finite element methods, CAE and software engineering, and artificial intelligence/expert systems (AI/ES) concepts. The role of each of these engineering technologies in the development of a unified design methodology is illustrated. A software system DESIGN-OPT has been developed for both size and shape optimization of structural components subjected to static as well as dynamic loadings. By integrating this software with an automatic mesh generator, a geometric modeler and an attribute specification computer code, a software module SHAPE-OPT has been developed for shape optimization. Details of these software packages together with their applications to some 2- and 3-dimensional design problems are described.

  3. Development of Novel Corrosion Techniques for a Green Environment

    Directory of Open Access Journals (Sweden)

    Zaki Ahmad

    2012-01-01

    Full Text Available The synergistic effect of air pollution, brown clouds and greenhouse gasses is deleterious to human health and industrial products. The use of toxic inhibitors, chemicals in water treatment plants, and anti-fouling agents in desalination plants has contributed to the greenhouse effect. Conventional anti-corrosion techniques such as paints, coatings, inhibitor treatments, and cathodic protection paid no regard to greenhouse effect. Work on eco-friendly anti-corrosion techniques is scanty and largely proprietary. The use of nano-TiO2 particles introduced in alkyds and polyurethane-based coatings showed a higher corrosion resistance compared to conventional TiO2 coatings with significant photocatalytic activity to kill bacteria. The use of UV radiations for photo-inhibition of stainless steel in chloride solution can replace toxic inhibitors. Corrosion inhibition has also been achieved by using natural materials such as polymers instead of toxic chemical inhibitors, without adverse environmental impact. TiO2 films exposed to UV radiation have shown the capability to protect the steel without sacrificing the film. Self-healing materials with encapsulated nanoparticles in paints and coatings have shown to heal the defects caused by corrosion. These innovative techniques provide a direction to the corrosion scientists, engineers, and environmentalists who are concerned about the increasing contamination of the planet and maintaining a green environment.

  4. Development of advanced silicon radiation detectors for harsh radiation environment

    Groenlund, Tanja

    2012-01-01

    This thesis describes the development of advanced silicon radiation detectors and their characterization by simulations, used in the work for searching elementary particles in the European Organization for Nuclear Research, CERN. Silicon particle detectors will face extremely harsh radiation in the proposed upgrade of the Large Hadron Collider, the future high-energy physics experiment Super-LHC. The increase in the maximal fluence and the beam luminosity up to 1016 neq / cm2 and 1035 cm-2s-1 will require detectors with a dramatic improvement in radiation hardness, when such a fluence will be far beyond the operational limits of the present silicon detectors. The main goals of detector development concentrate on minimizing the radiation degradation. This study contributes mainly to the device engineering technology for developing more radiation hard particle detectors with better characteristics. Also the defect engineering technology is discussed. In the nearest region of the beam in Super-LHC, the only dete...

  4. Development of wide area environment accelerator operation and diagnostics method

    Science.gov (United States)

    Uchiyama, Akito; Furukawa, Kazuro

    2015-08-01

    Remote operation and diagnostic systems for particle accelerators have been developed for beam operation and maintenance in various situations. Even though fully remote experiments are not necessary, the remote diagnosis and maintenance of the accelerator is required. Considering remote-operation operator interfaces (OPIs), the use of standard protocols such as the hypertext transfer protocol (HTTP) is advantageous, because system-dependent protocols are unnecessary between the remote client and the on-site server. Here, we have developed a client system based on WebSocket, which is a new protocol provided by the Internet Engineering Task Force for Web-based systems, as a next-generation Web-based OPI using the Experimental Physics and Industrial Control System Channel Access protocol. As a result of this implementation, WebSocket-based client systems have become available for remote operation. Also, as regards practical application, the remote operation of an accelerator via a wide area network (WAN) faces a number of challenges, e.g., the accelerator has both experimental device and radiation generator characteristics. Any error in remote control system operation could result in an immediate breakdown. Therefore, we propose the implementation of an operator intervention system for remote accelerator diagnostics and support that can obviate any differences between the local control room and remote locations. Here, remote-operation Web-based OPIs, which resolve security issues, are developed.

    Reducing Emissions from Deforestation (REDD) aims to curb carbon emissions from deforestation by financially compensating forest owners. However, compensation based on the opportunity costs of REDD might underestimate true costs by failing to account for downstream economic values of current land uses, including employment and wealth generated by processing and service industries. A comprehensive analysis of REDD impacts should also include sociopolitical impacts. REDD might exclude people from forest land, causing demographic shifts, and the declining tax revenues from commodity production and associated industries might be a disincentive to government investment in forested regions to the detriment of forest communities and regional development. We argue for the need to recognize and appropriately compensate the full range of economic, social and political net costs of REDD. Copyright 2010 Elsevier Ltd. All rights reserved.

    The ever-changing demands of recruitment and retention, both nationally and at a local level, have resulted in many staff with little or no experience in managing a unit in a secure setting. This study aimed to elicit the views of a cross-section of unit-based staff and middle management, on their experiences of leadership and taking charge of a shift/unit. A qualitative descriptive design was adapted for this study. The data were collected using focus group interviews guided by semistructured interview schedules. Twenty-one subjects participated in three focus groups. The data were analyzed using Colaizzi's (1978) framework. Five themes emerged from the data analysis. These are: Perceived practical skills deficit, perceived difference in experience, training program, leadership skills, and teaching learning methods. The themes generated will provide a framework to develop a training program, which will prepare staff to take on a leadership role within a unit, if required.

    ASDEX Upgrade today delivers approximately 25 GBytes of data per week. To manage this demand, which in fact is a growth by a factor of two in the last 2 years, several improvements to the data acquisition (DAQ) system have been made to avoid bottlenecks and to enhance the usability. Modifications were done to the diagnostic clients to speed up the storage of big diagnostic files to the central analysis server. The diagnostic synchronization server has been modified to handle wait requests not only for raw but for any level of evaluated data files. The central analysis server has been upgraded to deliver the power to do synoptic data analysis on up to 500 MBytes/shot on a single multiprocessor machine in shared memory. Additionally a cluster of ten workstations for parallel applications has been built up for MHD equilibrium calculations and other CPU-intensive tasks. The Andrew File System (AFS) archive servers have been upgraded to more disk capacity, a redundant storage architecture and faster network connections. However, as a basis for these improvements the network backbone and the server connections have been moved from FDDI to Gigabit-Ethernet and single workstation connections from Ethernet to Fast-Ethernet. Performance analysis results give an impression of the achieved improvements. Other projects in conjunction with the DAQ system at ASDEX Upgrade are the 'hotlink' interface system development for the Soft-X-Ray and Mirnov-Probes diagnostics and the 'S-link' development for an enhanced electron cyclotron emission (ECE) diagnostic. Both will serve as prototypes for future real-time diagnostics, which shall be able to deliver processed data in real-time to other systems -- especially experiment control -- to achieve a possibly better experiment performance.

    2011-06-01

    The aim of the study was to develop a short Swedish standardized, factor analyzed and cross-validated, family and school psychosocial environment questionnaire (FSPE). The study was based on 244 Swedish girls and boys, 10-19 years old, who filled in the FSPE. Maximum likelihood factor analysis, promax rotation, yielded six primary factors, based on absolute ratings. Since the factors were somewhat correlated, two broader secondary factors, with satisfactory reliabilities, were also included in the form, named Warmth, support and openness from parents, siblings and peers, and Family conflicts and school discipline, respectively. Means and standard deviations for girls and boys showed sex differences in most of the factors. Because the children participated anonymously they could report about spanking without negative consequences. Indeed, 8.1% of the children had been spanked by their parents. Based on relative ratings, two factors were identified, covering environmental questions about "more than, the same as or less than" a sibling. Only 6.6% of the children rated their environment exactly the same on the Family Psychosocial Environment (FPE) factors, compared to a sibling within the family. Thus the majority reported environmental differences. Further research is proposed to evaluate such differences and relations to personality, genotype-environment correlation and genetic mediation. © 2011 The Author.

    Through the analysis of the development activities and the ecological environment in coastal of Hebei Province, China, an index system for evaluating the ecological environment effect, composed of 28 indices, was set up by the pressure, state and response subsystems. Using the comprehensive index evaluation method, the integrated effects of ecological environment index (EI) was calculated and its grading criterion was founded. The results showed that the ecological environment effect of Hebei Province coastal development varied from being relatively small, normal and then relatively large from 1984 to 2010, and its acceptance degree evolved from being acceptable to being unacceptable. Because the resource and environment pressures caused by coastal development were serious and a delay existed in the state relative to the response, the improvement of various measures in the response subsystem did not show a positive effect on the state, and the environmental quality of ocean showed a degrading trend. Due to the differences in coastal development pattern and strength, the ecological environment effect of development activities showed some spatial differences. The ecological environment effect of Qinhuangdao coastal development was the minimum, followed by Cangzhou and Tangshan. Cangzhou and Tangshan had reached unacceptable levels and needed to further strengthen the restoration and protection of ecological environment.

  18. Developing a constructivist learning environment in online postsecondary science courses

    Hackworth, Sylvester N.

    This Delphi study addressed the concerns of postsecondary educators regarding the quality of education received by postsecondary science students who receive their instruction online. This study was framed with the constructivist learning theory and Piaget's and Dewey's cognitive development theories. The overarching question addressed a gap in research literature surrounding the pedagogical practices that could be successfully applied to future postsecondary online science education. The panel consisted of 30 experts in the area of online postsecondary education. Qualitative data from the initial seed questions were used to create a Likert-type survey to seek consensus of the themes derived from participant responses. Participants reached agreement on six items: apply constructivism to science curricula, identify strengths and challenges of online collegiate students, explicate students' consequences due to lack of participation in discussion forums, ensure that online course content is relevant to students' lives, reinforce academic integrity, and identify qualities face-to-face collegiate science instructors need when transitioning to online science instructors. The majority of participants agreed that gender is not an important factor in determining the success of an online collegiate science student. There was no consensus on the efficacy of virtual labs in an online science classroom. This study contributes to positive social change by providing information to new and struggling postsecondary science teachers to help them successfully align their instruction with students' needs and, as a result, increase students' success.

  19. Assessment, development, and testing of glass for blast environments.

    Glass can have lethal effects including fatalities and injuries when it breaks and then flies through the air under blast loading (''the glass problem''). One goal of this program was to assess the glass problem and solutions being pursued to mitigate it. One solution to the problem is the development of new glass technology that allows the strength and fragmentation to be controlled or selected depending on the blast performance specifications. For example the glass could be weak and fail, or it could be strong and survive, but it must perform reliably. Also, once it fails it should produce fragments of a controlled size. Under certain circumstances it may be beneficial to have very small fragments, in others it may be beneficial to have large fragments that stay together. The second goal of this program was to evaluate the performance (strength, reliability, and fragmentation) of Engineered Stress Profile (ESP) glass under different loading conditions. These included pseudo-static strength and pressure tests and free-field blast tests. The ultimate goal was to provide engineers and architects with a glass whose behavior under blast loading is less lethal. A near-term benefit is a new approach for improving the reliability of glass and modifying its fracture behavior.

    Full Text Available The insistence on the definition of environmental protection is an aspiration which has served as prerequisites to the implementation of human rights in a global economic crises. European Regional System has traditionally been focused on the protection of civil and political rights. In the wake of environmental risks that imply the violation of human rights, the emphasis has been placed more on the social, economic and cultural. Collective mechanisms to appeal to the United Nations and the European Court of Human Rights, gave a number of decisions on matters implicating environmental laws and policies. What is to be noted, is the evolution of the guarantees provided under the European Convention on Human Rights, which refers to a substantial understanding of environmental protection, and also including procedural aspects related to the protection of the right to life, privacy, property, information and effective means of appeal. This evolution has been launched by the growing need for states to take preventive measures and policies to the requirements for a balanced sustainable economic development, avoiding environmental risks that imply the violation of human rights. Proportionality in the protection of the interests in this respect creates a context for a fair trial, but also promotes an open and constructive dialogue between judges and lawmakers to protect the public interest.

  1. Development of an interdisciplinary model cluster for tidal water environments

    Global climate change has a high potential to influence both the persistence and the transport pathways of water masses and its constituents in tidal waters and estuaries. These processes are linked through dispersion processes, thus directly influencing the sediment and solid suspend matter budgets, and thus the river morphology. Furthermore, the hydrologic regime has an impact on the transport of nutrients, phytoplankton, suspended matter, and temperature that determine the oxygen content within water masses, which is a major parameter describing the water quality. This project aims at the implementation of a so-called (numerical) model cluster in tidal waters, which includes the model compartments hydrodynamics, morphology and ecology. For the implementation of this cluster it is required to continue with the integration of different models that work in a wide range of spatial and temporal scales. The model cluster is thus suggested to lead to a more precise knowledge of the feedback processes between the single interdisciplinary model compartments. In addition to field measurements this model cluster will provide a complementary scientific basis required to address a spectrum of research questions concerning the integral management of estuaries within the Federal Institute of Hydrology (BfG, Germany). This will in particular include aspects like sediment and water quality management as well as adaptation strategies to climate change. The core of the model cluster will consist of the 3D-hydrodynamic model Delft3D (Roelvink and van Banning, 1994), long-term hydrodynamics in the estuaries are simulated with the Hamburg Shelf Ocean Model HAMSOM (Backhaus, 1983; Hein et al., 2012). The simulation results will be compared with the unstructured grid based SELFE model (Zhang and Bapista, 2008). The additional coupling of the BfG-developed 1D-water quality model QSim (Kirchesch and Schöl, 1999; Hein et al., 2011) with the morphological/hydrodynamic models is an

  12. Multiple Gate Delay Tracking Structures for GNSS Signals and Their Evaluation with Simulink, SystemC, and VHDL

    Directory of Open Access Journals (Sweden)

    Heikki Hurskainen

    2008-01-01

    Full Text Available Accurate delay tracking in multipath environments is one of the prerequisites of modern GNSS receivers. Several solutions have been proposed in the literature, both feedback and feedforward. However, this topic is still under active research focus, especially for mass-market receivers, where selection of lowcomplexity, nonpatented methods is preferred. Among the most encountered delay tracking structures implemented in today's receivers, we have the narrow correlator and the double-delta correlators. Both are heavily covered by various patents. The purpose of this paper is to introduce a new, generic structure, called multiple gate delay (MGD structure, which covers also the patented correlators but offers much more flexibility in the design process. We show how the design parameters of such a structure can be optimized, we argue the performance of this structure via detailed simulation results based on various simulators, such as Matlab/Simulink-based tool, GRANADA, and we test the implementation feasibility of MGD structures on actual devices, via SystemC and FPGA prototyping. One of the main advantages of the proposed structure is its high degree of flexibility, which allows the designer to choose among, to the authors' knowledge, nonpatented solutions with delay tracking accuracy comparable with that of the current state-of-art trackers.

A recommended methodology for translation and cultural adaptation of questionnaires was applied. Once this had been completed, three hundred and thirty-two young athletes completed the Talent Development Environment Questionnaire. The results revealed that the five factor solution Talent Development Environment Questionnaire was confirmed. With the exclusion of one item due to low factor loading, the Talent Development Environment Questionnaire-5 had robust statistical support for its factor structure (χ2 (df = 305 = 499.64, p<0.01, CFI = 0.90, RMSEA = 0.045, SRMR = 0.055. It also demonstrated adequate convergent and discriminant validity. While the internal reliability was lower than in previous studies, it revealed acceptable levels. Specifically the overall 27 item Talent Development Environment Questionnaire-5 had a Cronbach α score of .877, and the reliability scores for individual factors 1-5 were .622; .761; .658; .605; .602 respectively. As such, it is recommended that the Spanish Talent Development Environment Questionnaire-5 can be used with confidence in Spain in both applied and research settings.

    This paper analyzes the relationship among the inhabited environment, infrastructure development and environmental impacts in China’s heavily urbanized Yangtze River Delta region. Using primary human environment data for the period 2006-2014, we examine factors affecting the inhabited environment and infrastructure development: urban population, GDP, built-up area, energy consumption, waste emission, transportation, real estate and urban greenery. Then we empirically investigate the impact of advanced urbanization with consideration of cities’ differences. Results from this study show that the growth rate of the inhabited environment and infrastructure development is strongly influenced by regional development structure, functional orientations, traffic network and urban size and form. The effect of advanced urbanization is more significant in large and mid-size cities than huge and mega cities. Energy consumption, waste emission and real estate in large and mid-size cities developed at an unprecedented rate with the rapid increase of economy. However, urban development of huge and mega cities gradually tended to be saturated. The transition development in these cities improved the inhabited environment and ecological protection instead of the urban construction simply. To maintain a sustainable advanced urbanization process, policy implications included urban sprawl control polices, ecological development mechanisms and reforming the economic structure for huge and mega cities, and construct major cross-regional infrastructure, enhance the carrying capacity and improvement of energy efficiency and structure for large and mid-size cities.

  18. Bridging Theory and Practice: Developing Guidelines to Facilitate the Design of Computer-based Learning Environments

    Directory of Open Access Journals (Sweden)

    Lisa D. Young

    2003-10-01

    Full Text Available Abstract. The design of computer-based learning environments has undergone a paradigm shift; moving students away from instruction that was considered to promote technical rationality grounded in objectivism, to the application of computers to create cognitive tools utilized in constructivist environments. The goal of the resulting computer-based learning environment design principles is to have students learn with technology, rather than from technology. This paper reviews the general constructivist theory that has guided the development of these environments, and offers suggestions for the adaptation of modest, generic guidelines, not mandated principles, that can be flexibly applied and allow for the expression of true constructivist ideals in online learning environments.

    Harms, P D; Roberts, Brent W; Winter, David

    2006-07-01

    The continuity and change of the needs and evaluations of the college environment and person-environment fit (PE fit) with the college environment were studied in a 4-year longitudinal study of students (N = 191). Perceptions of the environment changed more dramatically than corresponding self-perceived needs. PE fit demonstrated moderate levels of consistency over the 4-year span, but no significant increases in mean levels were found over time. Antecedents to PE fit in the college environment included both intelligence and openness to experience. Outcomes associated with PE fit included changes in personality traits linked to openness to experience and higher academic achievement. The implications of the findings for personality development and the relationship of PE fit to successful outcomes are discussed.

    As policy strategies are rapidly being developed to address childhood overweight, a system was developed to systematically and reliably classify state policies related to the school nutrition environment. This study describes the development process, the inter-rater reliability to code state policies enacted as of December 2003, and the variability in state policies related to the school nutrition environment. The development of the School Nutrition Environment State Policy Classification System (SNESPCS) included a comprehensive review of published literature, reports from government and nongovernmental sources, input from an expert panel, and select experts. Baseline statutes and regulations for each of the 50 states and the District of Columbia were retrieved from Westlaw (data retrieved in 2005-2006 and analyzed in 2006) and pilot testing of the system was conducted. SNESPCS included 11 policy areas that relate to a range of environmental and surveillance domains. At baseline, states had no (advertising/promotion and preferential pricing) or modest (school meal environment, reimbursable school meals, coordinating or advisory councils, body mass index screening) activities in many of the policy areas. As of 2003, 60% of the states had policies related to the sale of foods in school that compete with the school meal program. Evaluation of policies that affect the school-nutrition environment is in its earliest stage. SNESPCS provides a mechanism for assessing variation in state policies that can be incorporated in an evaluation framework aimed at elucidating the impact of state policies on the school environment, social norms, and children's dietary behaviors in schools.

    Full Text Available Because of the effects of globalization and because of the changes in social-political situation in world, the multicultural environment in Latvia is also changing. Latvia is becoming more and more attractive for foreign citizens from Europeand the same for citizens from elsewhere, that choose to settle here permanently or only for a period of time. That is a considerable challenge for education and healthcare. Workers in field of medicine, and also podology must guide their professional carreer development to the changing multicultural environment. That is why needs of young specialists are also changing , with knowledge, skills and competencies necessary in their profession, specialists must develop creativity and critical thinking, insight of values and culture, humanism and citizenship, decision-making and problem- solving skills as well as entrepreneurial abilities and communication skills. In the process of prepearing new podologists for work in a multicultural environment development of those personal attributes that are made of tact and diplomacy, as well as development of basic skill sets that include learning skill and skill to make compromises, career management skill set development as characterized by ability to collaborate , ability to notice changes in working environment and ability to give support become more important. The goal of this article is to describe, theoretically and empirically, the development of necessary carreer management skills for work in multicultural environment to new podologists

    Full Text Available Previous research indicates that the home environment is a significant factor in early child development. The present study examined influence of the multidimensional home environment on young Japanese children’s motor development. A Japanese translation of the Affordances in the Home Environment for Motor Development-Self Report (AHEMD-SR was used to assess home motor affordances in 262 families. Motor ability was assessed by parental report using the Enjoji Infant Analytic Developmental Test. We also asked parents to rate their own physical activity in terms of level and years of experience. As results, we found that the home environment in Japan was generally sufficient for children’s motor development and that children’s access to Fine Motor Toys (FMT and Gross Motor Toys (GMT had the strongest influence on their development. Analysis also indicated that AHEMD-SR scores were higher for children of parents who had some level of physical activity experience compared to children whose parents indicated no physical activity experience. Parents’ self-reported activity level was correlated with higher scores for the subscales FMT and GMT and for total AHEMD-SR score. These results indicate that both the physical and social-psychological environments (parental experience and views of the home influenced children’s motor development.

This document is organized into fourteen specific natural environment disciplines of which some are winds, atmospheric models, thermal radiation, precipitation-for-icing, cloud cover, atmospheric electricity, geologic hazards, toxic chemical release by propulsion systems, and sea state. Atmospheric phenomena play a significant role in the design and flight of aerospace vehicles and in the integrity of the associated aerospace systems and structures. Environmental design criteria guidelines in this document are based on measurements and observations of atmospheric and climatic phenomena relative to various aerospace development, operational, and vehicle launch locations. The natural environment criteria guidelines data presented in this Handbook were formulated based on discussions with and requests from engineers involved in aerospace vehicle development and operations. Therefore, they represent responses to actual engineering problems and are not just a general compilation of environmental data. The Handbook addresses the basis for the information presented, the interpretations of the terrestrial environment guideline given in the Handbook, and its application to the development of aerospace vehicle design requirements. Specific examples of the Handbook content and associated "lessons lenmed" are given in this paper.

    Early childhood development plays a key role in a child's future health, educational success, and economic status. However, suboptimal early development remains a global challenge. This study examines the influences of quality of the home learning environment (HOME) and child stunting in the first year of life on child development. We used data collected from a randomized controlled trial of preconceptional micronutrient supplementation in Vietnam (n = 1,458). The Bayley Scales of Infant Development-III were used to assess cognition, language, and motor development domains at 2 years. At 1 year, 14% of children were stunted, and 15%, 58%, and 28% of children lived in poor, medium, and high HOME environments, respectively. In multivariate generalized linear regression models, living in a high HOME environment was significantly associated with higher scores (0.10 to 0.13 SD) in each of the developmental domains. Stunted children scored significantly lower for cognitive, language, and motor development (-0.11 to -0.18), compared to nonstunted children. The negative associations between stunting on development were modified by HOME; the associations were strong among children living in homes with a poor learning environment whereas they were nonsignificant for those living in high-quality learning environments. In conclusion, child stunting the first year of life was negatively associated with child development at 2 years among children in Vietnam, but a high-quality HOME appeared to attenuate these associations. Early interventions aimed at improving early child growth as well as providing a stimulating home environment are critical to ensure optimal child development. © 2017 John Wiley & Sons Ltd.

    Full Text Available In recent years, many studies was developed to find out different solutions for the induction motor control having the features of precise and quick torque response and reduction of the complexity of field oriented algorithms. The Direct Torque Control (DTC method is the most recent control technique used to achieve these requirements. Designing power electronic systems is based on accurate knowledge of the designers. The procedure allowing adjustment performances in order to respect requirements follows a “try and test” scheme. The design is done step by step, sizing each part but without computer assistance. In this paper, we show how a high level language can be used to model a system including many domains like digital and analogue electronics, power electronics, electrical motor, control, etc. Each domain must be described at the good level of abstraction taking into account the wanted level of results. When the system and its simulation are available, it is possible to drive many studies in a virtual way: comparison of control algorithms, technological choices, etc. At this level, it is possible to talk about Virtual Prototyping of a complex system. We show in this paper how this approach can be applied to the DTC Control of an asynchronous motor in order to optimize the control algorithm and the embedded hardware.

    This review addresses the central role played by multimodal interactions in neurocognitive development. We first analyzed our studies of multimodal verbal and nonverbal cognition and emotional interactions within neuronal, that is, natural environments in typically developing children. We then tried to relate them to the topic of creating artificial environments using mobile toy robots to neurorehabilitate severely autistic children. By doing so, both neural/natural and artificial environments are considered as the basis of neuronal organization and reorganization. The common thread underlying the thinking behind this approach revolves around the brain's intrinsic properties: neuroplasticity and the fact that the brain is neurodynamic. In our approach, neural organization and reorganization using natural or artificial environments aspires to bring computational perspectives into cognitive developmental neuroscience.

    Measurement technology for various key parameters in harsh environments (e.g., high-temperature and biomedical applications) continues to be limited. Wireless passive LC resonant sensors offer long service life and can be suitable for harsh environments because they can transmit signals without battery power or wired connections. Consequently, these devices have become the focus of many current research studies. This paper addresses recent research, key technologies, and practical applications relative to passive LC sensors used to monitor temperature, pressure, humidity, and harmful gases in harsh environments. The advantages and disadvantages of various sensor types are discussed, and prospects and challenges for future development of these sensors are presented.

  18. THE HIGHLY DEVELOPED INFORMATION AND EDUCATION ENVIRONMENT AS A PRECONDITION OF EDUCATIONAL SYSTEM REORGANIZATION

    Directory of Open Access Journals (Sweden)

    Y. K. Khenner

    2014-01-01

    Full Text Available The paper regards the development of the information and education environment of Russian universities as an important condition for successful reorganization of higher education. Taking as an example one of theUSuniversities, the author demonstrates the capacity of information education environment and its impact on the multilevel educational process. The comparative analysis of the existing information education environments of Russian an American universities reveals that such effective improvements as increasing number of students working on the individual curricula,__ implementation of the learning outcome monitoring, inclusive education, etc require immediate and substantial development of the information education environment of Russian universities. Both the development level and informational content of the environment in question remain unsatisfactory due to the financial, economic and staff related reasons. Consequently, the higher school reorganization is lagging behind retarded by the lack of synchronization between the attempts to improve the education quality and competitiveness on the one hand, and insufficient level of the information education environment characteristic of Russian universities on the other hand.

  19. Environmental planning, ecosystem science, and ecosystem approaches for integrating environment and development

    Science.gov (United States)

    Slocombe, D. Scott

    1993-05-01

    Currently popular concepts such as sustainable development and sustainability seek the integration of environment and development planning. However, there is little evidence that this integration is occurring in either mainstream development planning or environmental planning. This is a function of the history, philosophies, and evolved roles of both. A brief review of the experience and results of mainstream planning, environmental planning, and ecosystem science suggests there is much in past scientific and professional practice that is relevant to the goal of integrated planning for environment and development, but still such commonly recommended reforms as systems and multidisciplinary approaches, institutional integration, and participatory, goal-oriented processes are rarely achieved. “Ecosystem approaches,” as developed and applied in ecology, human ecology, environmental planning, anthropology, psychology, and other disciplines, may provide a more transdisciplinary route to successful integration of environment and development. Experience with ecosystem approaches is reviewed, their advantages and disadvantages are discussed, and they are compared to traditional urban and regional planning, environmental planning, and ecosystem science approaches. Ultimately a synthesis of desirable characteristics for a framework to integrate environment and development planning is presented as a guide for future work and a criterion for evaluating existing programs.

    Full Text Available In the present study we aim to analyze and deepen an important category of expenditure funded from local budgets namely expenses on services and public development, dwellings, environment and water. Our approach begins with determining scientifically the place of such expenses in local spending by clarifying their content and role. A special part of the article treats the particularities and financing of public utilities and finance and making investments related to public utility systems. The research is based on quantitative analysis of expenses for services and public development, dwellings, environment and water in local budgets from existing data in the Statistical Yearbook of Romania and highlights the structure of these types of expenditures and their place within public expenses in local budgets. The study includes an analysis of the dynamics of the share hold by expenses for services and public development, housing, environment and water in total expenditures from local budgets. The research carries out that the evolution and structure of expenses for services and public development, housing, environment and water from local budgets is determined by several variables that differ from one administrative territorial unit to another: the village area, length of roads, sewage system, number and social structure of the population. The research shows that within expenditures for public services and development, dwellings, environment and water the biggest share of expenditure is hold by expenditure on housing, public services and development (about 64%. During the period 2000-2013, the dynamics of expenditures for services and public development, dwellings, environment and water in the total expenditure of local budgets is sinusoidal, reaching a minimum threshold of 11.1% in 2011.

    2011-01-01

    Full Text Available Each classroom has its own assessment environment perceived by the students and springs from the teacher's assessment practices. Although students' perceptions of the assessment environment may influence their achievement-related outcomes, little attention has been given to the measurement of perceived classroom assessment environment. This study reports on the development and datametric properties of a scale measuring students' perceptions of the classroom assessment environment. A total of 450 students enrolled in the tenth grade English language classes at Muscat public schools in Oman completed the scale. Results yielded two subscales of the perceived classroom assessment environment: learning-, and performance-oriented environments. The correlations between them suggested that they represented unique aspects of the classroom assessment environment as perceived by the students. Additional validity evidence was obtained through gender differences and correlations of the subscales scores with the total scores received in the subject at end of the semester. Reliability analyses showed that the subscales' scores had relatively moderate levels of internal consistency. Implications and recommendations for classroom instruction and assessment as well as for future research are discussed.

    Plant growth and development is profoundly influenced by environmental conditions that laboratory experimentation typically attempts to control. However, growth conditions are not uniform between or even within laboratories and the extent to which these differences influence plant growth and development is unknown. Experiments with wild-type Arabidopsis thaliana were designed to quantify the influences of parental environment and seed size on growth and development in the next generation. A single lot of seed was planted in six environmental chambers and grown to maturity. The seed produced was mechanically sieved into small and large size classes then grown in a common environment and subjected to a set of assays spanning the life cycle. Analysis of variance demonstrated that seed size effects were particularly significant early in development, affecting primary root growth and gravitropism, but also flowering time. Parental environment affected progeny germination time, flowering and weight of seed the progeny produced. In some cases, the parental environment affected the magnitude of (interacted with) the observed seed size effects. These data indicate that life history circumstances of the parental generation can affect growth and development throughout the life cycle of the next generation to an extent that should be considered when performing genetic studies. © 2010 Blackwell Publishing Ltd.

    2009-05-01

    Intelligent opto-electric instruments are synthetically products that are involved with optics, mechanics and electronics. An effective development platform is necessary for efficient development. According to the conception of integrated development and manufacture, an architecture of integrated development environment based on resource library and resource management is presented to resolve the shortcoming of weak reusability and portability of resource, long periods of development and weak openness of existing platform. The development environment provides a suite of standard resource integration and management interface to integrate and regulate existing models, algorithms, tools and components. Then reusable typical resource library is established by adding third party resource that accords with the interface defined. Resources in library are expressed as reusable components. System modeling, rapid prototype developing and online simulating and testing can be implemented rapidly and reliably by utilizing corresponding resources in library, so technique difficulty and development periods can be reduced, and development efficiency is improved. Because of describing resource by metadata and XML, the architecture is flexible and open, and can be improved continuously to adapt to development and upgrade of various intelligent opto-electric instrument to meet the requirement of efficient integrated development and manufacture perfectly.

    2016-12-01

    Full Text Available Restrictive environments can be defined as an area within a territorial system where development is constrained either by natural factors or anthropogenic factors. This paper aims to identify restrictive environments through multi-criteria analysis of Romania’s South West Oltenia development region, known for its issues regarding open-pit mining, desertification or flood risk. In order to achieve this, I proposed a typology of restrictive environments, based on an extensive literature review of natural and anthropogenic factors that can limit development. For each of the ten environmental restrictiveness types identified, several criteria were proposed, which were then weighted as a result of a questionnaire addressed to experts in the field of territorial planning. Based on the questionnaire results, an index of environmental restrictiveness is computed at LAU 2 level for the entire South-West Oltenia development region. The territorialized index highlights the environmental restrictiveness of areas susceptible to flood risk (e.g. along the Jiu valley, but also the problems faced by mining areas (Motru-Rovinari or isolated mountain areas. The computed index represents a first step towards the definition of potential inter-communal cooperation structures, that could become the object of territorial planning instruments aimed at mitigating restrictive environments.

    Bradley, Robert H; Putnick, Diane L

    2012-01-01

    This study examined home environment conditions (housing quality, material resources, formal and informal learning materials) and their relations with the Human Development Index (HDI) in 28 developing countries. Home environment conditions in these countries varied widely. The quality of housing and availability of material resources at home were consistently tied to HDI; the availability of formal and informal learning materials a little less so. Gross domestic product (GDP) tended to show a stronger independent relation with housing quality and material resources than life expectancy and education. Formal learning resources were independently related to the GDP and education indices, and informal learning resources were not independently related to any constituent indices of the overall HDI. © 2012 The Authors.

    2003-01-01

    Reducing size and weight of spacecraft, along with demanding increased performance capabilities, introduces many uncertainties in the engineering design community on how spacecraft and spacecraft systems will perform in space. The engineering design community is forever behind on obtaining and developing new tools and guidelines to mitigate the harmful effects of the space environment. Adding to this complexity is the push to use Commercial-off-the-shelf (COTS) and shrinking microelectronics behind less shielding utilizing new materials. The potential usage of unproven technologies such as large solar sail structures and nuclear electric propulsion introduces new requirements to develop new engineering tools. In order to drive down these uncertainties, NASA s SEE Program provides resources for technology development to accommodate or mitigate these harmful environments on spacecraft. This paper will describe the current SEE Program's, currently funded activities and possible future developments.

  19. The effects of economic development and built environment on diabetes in CHINA.

    2017-09-29

    With rapid economy growth, the prevalence of obesity, and related chronic diseases, has increased greatly. Although this has been widely recognized, little attention has been paid to the influence of built environment and economic growth, particularly for developing countries. The main purpose of this study is to investigate the potential relationship between the prevalence of diabetes and the built environment while considering the effects of socioeconomic change in China. Three nationally representative samples are constructed and employed mainly based on various sources of data, such as the China National Nutrition and Health Survey, World Health Organization, and China Health and Retirement Longitudinal Survey in 2013. The explanatory variables representing the built environment and influential factors include the health outcomes, economic indicators, local health facilities, regional dummies, and demographic features. OLS, robust regressions, and a set of binary choice models are used to estimate the possible relationship. It is suggested that the prevalence of diabetes is associated with both the broader built environment and individual economic factors in China. China's sharp economic growth in the recent decades has greatly increased the prevalence of obesity and diabetes, when also considering other influential factors. Although the results can not specify causal mechanism, some useful results can be clearly discovered and subsequently a few important policy implications can be provided for the sustainable and healthy development of China's urban planning or built environment.

    2008-01-01

    Full Text Available Abstract Currently available toolsets for the development of embedded systems adopt traditional architectural styles and do not cover the whole requirements of the development process, with extensibility being the major drawback. In this paper, a service-oriented architectural framework that exploits semantic web is defined. Features required in the development process are defined as web services and published into the public domain, so as to be used on demand by developers to construct their projects' specific integrated development environments (IDEs. The infrastructure required to build a web service-based IDE is presented. Specific web services are defined and the way these services affect the development process is discussed. Special focus is given on the device model and the means that such a modelling can significantly improve the development process. A prototype implementation demonstrates the applicability and usefulness of the proposed demand-led development process in the industrial automation domain.

    Full Text Available Information and Communication Technology (ICT plays an important role in all sectors of activity, hence in tourism sector too. Starting from this fact, authors consider as important identifying and implementing best practices in electronic environment for sustainable development of tourism in Romania. Traditional tourism - implying at all stages specialized human support – knows profound modifications. Today, current statistics show that more and more people dive into virtual environment for visualizing new places and finding out new information, for cross border business meetings, for entertainment as well as for communication. Hence, the current paper – presenting the results of a complex quantitative research, aims to discuss about the influence of virtual environment upon tourism in what concerns informing, planning and organizing a trip. The obtained results led towards recommendations for developing ICT facilities, especially for business tourism, for an extensive use of web-GIS applications during the three phases of travel, for improving infrastructure and mobile applications, especially for young people, as well as for implementing digital systems that investigate tourists’ behaviour and personalize tourism offers. The final purpose of the paper is to contribute to the development of best practices that lead to economic growth in tourism, by quantifying the impact of electronic environment upon visiting experiences.

  10. PLUMED-GUI: An environment for the interactive development of molecular dynamics analysis and biasing scripts

    Science.gov (United States)

    Giorgino, Toni

    2014-03-01

    PLUMED-GUI is an interactive environment to develop and test complex PLUMED scripts within the Visual Molecular Dynamics (VMD) environment. Computational biophysicists can take advantage of both PLUMED’s rich syntax to define collective variables (CVs) and VMD’s chemically-aware atom selection language, while working within a natural point-and-click interface. Pre-defined templates and syntax mnemonics facilitate the definition of well-known reaction coordinates. Complex CVs, e.g. involving reference snapshots used for RMSD or native contacts calculations, can be built through dialogs that provide a synoptic view of the available options. Scripts can be either exported for use in simulation programs, or evaluated on the currently loaded molecular trajectories. Script development takes place without leaving VMD, thus enabling an incremental try-see-modify development model for molecular metrics.

  11. Early childhood cognitive development and parental cognitive stimulation: evidence for reciprocal gene-environment transactions.

    Science.gov (United States)

    Tucker-Drob, Elliot M; Harden, K Paige

    2012-03-01

    Parenting is traditionally conceptualized as an exogenous environment that affects child development. However, children can also influence the quality of parenting that they receive. Using longitudinal data from 650 identical and fraternal twin pairs, we found that, controlling for cognitive ability at age 2 years, cognitive stimulation by parents (coded from video recorded behaviors during a dyadic task) at 2 years predicted subsequent reading ability at age 4 years. Moreover, controlling for cognitive stimulation at 2 years, children's cognitive ability at 2 years predicted the quality of stimulation received from their parents at 4 years. Genetic and environmental factors differentially contributed to these effects. Parenting influenced subsequent cognitive development through a family-level environmental pathway, whereas children's cognitive ability influenced subsequent parenting through a genetic pathway. These results suggest that genetic influences on cognitive development occur through a transactional process, in which genetic predispositions lead children to evoke cognitively stimulating experiences from their environments. © 2011 Blackwell Publishing Ltd.

    SummaryThe Okavango basin comprises the Cuito and Cubango active catchment areas in Angola, in addition to the Kavango-Okavango non-active catchment in northern Namibia and Botswana. The Okavango River water and its ecosystem resources are critically important sources of livelihoods for people in the basin. Pressures from livelihoods and development are already impacting on the environment. These pressures may increase in the future due to the rapid increase in population, the peace process and associated resettlement activities in Angola, and major development initiatives in Botswana and Namibia. For instance, possible future increase in water abstraction from the Okavango River may affect the long-term environmental sustainability of the Okavango Delta by minimizing channel shifting and thereby reducing spatial biodiversity. The paper argues that while conservation of the natural environment is critical, the pressing development needs must be recognized. The reduction of poverty within the basin should be addressed in order to alleviate adverse effects on the environment. The paper recommends that the development of sustainable tourism and community-based natural resource management initiatives may be appropriate strategies for reaching the Millennium Development Goals of poverty alleviation and achievement of environmental sustainability in the Okavango Basin. These initiatives have a comparative advantage in this area as demonstrated by the performance of the existing projects.

    2014-06-01

    Full Text Available If we consider the role of education and its implications in the formation of a critical and conscious user of architecture, it is obvious that the development of educational strategies related to our common space and environment become fundamental. The comprehension of the concept of sustainable development is essential. Therefore, it is worth reflecting on how to develop proper programs at all educational levels to promote critical and responsible attitudes towards the common environment covering all the aspects that should shape the concepts of sustainable spatial and environmental development, enhancing at the same time great freedom regarding the formal aspects of architecture. The ideas presented in the article are supported by an empirical research on the image of architecture and the environment, held among secondary school students. The research based on the idea that one of the most efficient critical attitudes towards the world would be to develop an unconditional tie of the art work with everyday life conditions. That is why part of the activities within the research was devoted to recycling relevant architectural spaces. The results show a very heterogeneous image of architecture in the eyes of the students which sometimes overvalues contrasts and originality, disregarding tradition

    2001-01-01

    Full Text Available This paper describes the development and implementation of a distributed job execution environment for highly iterative jobs. An iterative job is defined here as a binary code that is run multiple times with incremental changes in the input values for each run. An execution environment is a set of resources on a computing platform that can be made available to run the job and hold the output until it is collected. The goal is to design a complete, object-oriented execution system that runs a variety of jobs with minimal changes. Areas of code that are unique to a specific type of job are decoupled from the rest. The system allows for fine-grained job control, timely status notification and dynamic registration and deregistration of execution platforms depending on resources available. Several objected-oriented technologies are employed: Java, CORBA, UML, and software design patterns. The environment has been tested using a simulation code, INS2D.

    Full Text Available Understanding the effects of environmental stimulation in autism can improve therapeutic interventions against debilitating sensory overload, social withdrawal, fear and anxiety. Here, we evaluate the role of environmental predictability on behavior and protein expression, and inter-individual differences, in the valproic acid (VPA model of autism. Male rats embryonically exposed (E11.5 either to VPA, a known autism risk factor in humans, or to saline, were housed from weaning into adulthood in a standard laboratory environment, an unpredictably enriched environment, or a predictably enriched environment. Animals were tested for sociability, nociception, stereotypy, fear conditioning and anxiety, and for tissue content of glutamate signaling proteins in the primary somatosensory cortex, hippocampus and amygdala, and of corticosterone in plasma, amygdala and hippocampus. Standard group analyses on separate measures were complemented with a composite emotionality score, using Cronbach’s Alpha analysis, and with multivariate profiling of individual animals, using Hierarchical Cluster Analysis. We found that predictable environmental enrichment prevented the development of hyper-emotionality in the VPA-exposed group, while unpredictable enrichment did not. Individual variation in the severity of the autistic-like symptoms (fear, anxiety, social withdrawal and sensory abnormalities correlated with neurochemical profiles, and predicted their responsiveness to predictability in the environment. In saline-exposed animals, the association between socio-affective behaviors, neurochemical profiles and environmental predictability was negligible. This study suggests that rearing in a predictable environment prevents the development of hyper-emotional features in animals exposed to an autism risk factor, and demonstrates that unpredictable environments can lead to negative outcomes, even in the presence of environmental enrichment.

    Eating, or nutrition, environments are believed to contribute to obesity and chronic diseases. There is a need for valid, reliable measures of nutrition environments. This article reports on the development and evaluation of measures of nutrition environments in retail food stores. The Nutrition Environment Measures Study developed observational measures of the nutrition environment within retail food stores (NEMS-S) to assess availability of healthy options, price, and quality. After pretesting, measures were completed by independent raters to evaluate inter-rater reliability and across two occasions to assess test-retest reliability in grocery and convenience stores in four neighborhoods differing on income and community design in the Atlanta metropolitan area. Data were collected and analyzed in 2004 and 2005. Ten food categories (e.g., fruits) or indicator food items (e.g., ground beef) were evaluated in 85 stores. Inter-rater reliability and test-retest reliability of availability were high: inter-rater reliability kappas were 0.84 to 1.00, and test-retest reliabilities were .73 to 1.00. Inter-rater reliability for quality across fresh produce was moderate (kappas, 0.44 to 1.00). Healthier options were higher priced for hot dogs, lean ground beef, and baked chips. More healthful options were available in grocery than convenience stores and in stores in higher income neighborhoods. The NEMS-S tool was found to have a high degree of inter-rater and test-retest reliability, and to reveal significant differences across store types and neighborhoods of high and low socioeconomic status. These observational measures of nutrition environments can be applied in multilevel studies of community nutrition, and can inform new approaches to conducting and evaluating nutrition interventions.

    The home environment is an important setting for the development of weight status in adolescence. At present a limited number of valid and reliable tools are available to evaluate the weight-related comprehensive home environment of this population. The goal of this research was to develop the Multidimensional Home Environment Scale which measures multiple components of the home. It includes psychological, social, and environmental domains from the perspective of an adolescent and the mother. Items were generated based on a literature review and then assessed for content validity by an expert panel and focus group in the target population. Internal consistency reliability was determined using Cronbach's α. Principal components analysis with varimax rotation was employed for assessment of construct validity. Temporal stability was evaluated using paired sample t-tests and bivariate correlations between responses at two different times, 1-2weeks apart. Associations between adolescent and mother responses were utilized for convergent validity. The final versions contained 32-items for adolescents and 36-items for mothers; these were administered to 218 adolescents and mothers. The subscales on the questionnaires exhibited high construct validity, internal consistency reliability (adolescent: α=0.82, mother: α=0.83) and test-retest reliability (adolescent: r=0.90, p<0.01; mother: r=0.91, p<0.01). Total home environment scores were computed, with greater scores reflecting a better health environment. These results verify the utility of the MHES as a valid and reliable instrument. This promising tool can be utilized to capture the comprehensive home environment of young adolescents (11-14years old). Copyright © 2016 Elsevier Ltd. All rights reserved.

All of us that are concerned about the environment should ask ourselves if the increase in capital mobility associated with the world-wide process of  liberalization, deregulation and privatization, known as the Neo-liberal global regime, has contributed to the problems of higher emissions, ozone layer destruction, and pollution of water sources, as well as to create false economic bubbles that lead to increased consumption in these regions whilst forcing the destruction of the environment by the poor in order to survive and cope with the roles their society demands. Neo-liberal practices such as those enforced in developing countries like Colombia, while seeking to attract foreign investment to push their economies, tend to generate a false aggregated demand growth that in most cases is not sustainable in the long term, increases global unemployment, unleash destructive competitive processes and weaken government’s ability to regulate business in the citizens` best interests.Este artículo trata sobre el impacto de inversión extranjera directa en economíasen vías de desarrollo y el medio ambiente. Todos los que nos preocupamos por elmedio ambiente debemos preguntarnos, si el aumento en la movilidad de capitales asociada con el proceso mundial de liberalización, desregulación y privatización,conocido como “neoliberalismo”, ha contribuido a problemas de emisiones másaltas, destrucción de la capa de ozono, y polución de fuentes de agua, así como a lacreación de falsas burbujas económicas que llevan a aumentar el consumo en estasregiones, obligando a los más pobres a destruir el medio ambiente para sobrevivir ypoder cumplir con los roles impuestos por la sociedad.

    Full Text Available We are developing a unified distributed communication environment for processing of spatial data which integrates web-, desktop- and mobile platforms and combines volunteer computing model and public cloud possibilities. The main idea is to create a flexible working environment for research groups, which may be scaled according to required data volume and computing power, while keeping infrastructure costs at minimum. It is based upon the "single window" principle, which combines data access via geoportal functionality, processing possibilities and communication between researchers. Using an innovative software environment the recently developed planetary information system (http://cartsrv.mexlab.ru/geoportal will be updated. The new system will provide spatial data processing, analysis and 3D-visualization and will be tested based on freely available Earth remote sensing data as well as Solar system planetary images from various missions. Based on this approach it will be possible to organize the research and representation of results on a new technology level, which provides more possibilities for immediate and direct reuse of research materials, including data, algorithms, methodology, and components. The new software environment is targeted at remote scientific teams, and will provide access to existing spatial distributed information for which we suggest implementation of a user interface as an advanced front-end, e.g., for virtual globe system.

    Heritage towns and buildings are invaluable cultural assets of a nation, and are extremely useful in manifesting place identity, and crucial in promoting tourism. These places of cultural significance should be made accessible to everyone including people with mobility or sensory impairments, the elderly, parents with small children and those who are temporarily disabled due to injury or illness. By creating a accessible heritage environment not only can you cater towards the increasing population of disabled people, but you could increase the number of cultural properties as resources of a nation through 'accessible tourism'. However the differences in implementation of barrier-free tourism for historic buildings and places are rather large between developed and developing countries such as Malaysia. This paper serves as preliminary study on accessibility of heritage environment in Malaysia. First, review of some related definitions, perception toward disability, and background studies in disability movement will be discussed to achieve better understanding of the increasing population of disabled people and how it would affect the development of infrastructure in the built environment. Second, it will look into existing legislation concerning heritage conservation and legislation on provision of access for the disabled in Malaysia and other developing countries. Finally, this paper seeks to find gaps between these legislations and conclude with some recommendations.

    "Telepresence" is an interesting field that includes virtual reality implementations with human-system interfaces, communication technologies, and robotics. This paper describes the development of a telepresence robot called Telepresence Robot for Interpersonal Communication (TRIC) for the purpose of interpersonal communication with the elderly in a home environment. The main aim behind TRIC's development is to allow elderly populations to remain in their home environments, while loved ones and caregivers are able to maintain a higher level of communication and monitoring than via traditional methods. TRIC aims to be a low-cost, lightweight robot, which can be easily implemented in the home environment. Under this goal, decisions on the design elements included are discussed. In particular, the implementation of key autonomous behaviors in TRIC to increase the user's capability of projection of self and operation of the telepresence robot, in addition to increasing the interactive capability of the participant as a dialogist are emphasized. The technical development and integration of the modules in TRIC, as well as human factors considerations are then described. Preliminary functional tests show that new users were able to effectively navigate TRIC and easily locate visual targets. Finally the future developments of TRIC, especially the possibility of using TRIC for home tele-health monitoring and tele-homecare visits are discussed.

    Preparation has yet to be completed for the 1992 Earth Summit, UN Conference on Environment and Development (UNCED), in Rio de Janeiro, Brazil. Nonetheless, it has been planned as a forum in which recommendations will be made to governments and international organizations on how to alleviate environmental damage caused by human activities and how to prevent future damage without retarding development in the Third World. It will declare basic principles for national and individual conduct regarding environmental preservation and sustainable development; adopt international conventions to protect biodiversity and manage climatic change; lay out Agenda 21 activities as specified by UNCED; provide an agenda to help Third World governments manage environmental matters; and provide an agenda for improving the transfer of technology to developing countries. Where biotechnology is concerned, scientists and policy makers in developing countries have shown their interest. Limited resources and capabilities, however, constrain their abilities to engage in serious research and development. International organizations such as the UN Industrial Development Organization (UNIDO) may help UNCED and developing countries with biotechnology. Since 1986, UNIDO has held the International Centre for Genetic Engineering and Biotechnology (ICGEB) as a special project. The ICGEB conducts research and development (R&D) on high priority topics in developing countries; trains scientific and technical personnel from member countries in advanced biotechnology techniques; helps member countries implement and operate ICGEB-affiliated R&D and training centers; and manages an information exchange for internationally affiliated centers. To maximize the potential of biotechnology to help Third World nations clear their environments of pollutants while safely exploiting natural resources, organizations should promote full use of available training resources; promote biosafety and the dissemination of

    2014-12-01

    Current reforms in mathematics education advocate the development of mathematical learning communities in which students have opportunities to engage in mathematical discourse and classroom practices which underlie algebraic reasoning. This article specifically addresses the pedagogical actions teachers take which structure student engagement in dialogical discourse and activity which facilitates early algebraic reasoning. Using videotaped recordings of classroom observations, the teacher and researcher collaboratively examined the classroom practices and modified the participatory practices to develop a learning environment which supported early algebraic reasoning. Facilitating change in the classroom environment was a lengthy process which required consistent and ongoing attention initially to the social norms and then to the socio-mathematical norms. Specific pedagogical actions such as the use of specifically designed tasks, materials and representations and a constant press for justification and generalisation were required to support students to link their numerical understandings to algebraic reasoning.

    Full Text Available For a city to be inclusive, its physical environment needs to be identified, characterized and assessed prior to transformations and improvements. Such identification is the first step to impact on politics for citizens with impairments and functional limitations since environmental obstacles limits their social participation. The objective of this research was to develop a comprehensive and applicable information set for the description of the physical environment in support of the implementation of the United Nations Convention on the rights of persons with disabilities in Quebec City’s context. We developed a taxonomy based on the Human Development Model – Disability Creation Process (HDM-DCP. We reviewed documents containing nomenclatures with respect to the specific case of Quebec City’s physical environment. We organized the information under the original taxa of the HDM-DCP, this was carried out via an iterative process where elements of similar type were organized into a common level of one hierarchical branch under general categories. When categories linking objects to broader subcategories were not already identified, we expanded the structure by creating new sub-categories or hybrids. Applicability of the developed taxonomy was tested through field analyses and testing (photos of street sections to determine whether it included all objects and infrastructures observed in the city. The resulting taxonomy was found to be useful in identifying/mapping elements of the physical environment. Both at the individual and collective level, it allows the identification of the elements that play a role in mobility, resulting in enhanced social participation or disabling situations for people with disabilities.

    The International Atomic Energy Agency (IAEA) is interested in increasing capabilities of IAEA safeguards inspectors to access information that would improve their situational awareness on the job. A mobile information platform could potentially provide access to information, analytics, and technical and logistical support to inspectors in the field, as well as providing regular updates to analysts at IAEA Headquarters in Vienna or at satellite offices. To demonstrate the potential capability of such a system, Pacific Northwest National Laboratory (PNNL) implemented a number of example capabilities within a PNNL-developed precision information environment (PIE), and using a tablet as a mobile information platform. PNNL’s safeguards proof-of-concept PIE intends to; demonstrate novel applications of mobile information platforms to international safeguards use cases; demonstrate proof-of-principle capability implementation; and provide “vision” for capabilities that could be implemented. This report documents the lessons learned from this two-year development activity for the Precision Information Environment for International Safeguards (PIE-IS), describing the developed capabilities, technical challenges, and considerations for future development, so that developers working to develop a similar system for the IAEA or other safeguards agencies might benefit from our work.

    Canine and human atopic dermatitis are multifaceted diseases whose clinical development may be influenced by several factors, such as genetic background, environment, secondary infections, food and psychological effects. The role of the environment has been extensively examined in humans but remains unclear in dogs. The aim of this study was to examine environmental factors in two genetically close breeds, Labrador and golden retrievers. Using standard criteria, atopic dogs in Switzerland and Germany were selected and compared with healthy individuals. Information on environmental factors was collected using a 46-question survey encompassing date and place of birth, way of life at the breeder's and owner's home, food and treatments. Univariate and multivariate logistic regression were used to assess the association between potential risk factors and disease status. The following parameters were associated with an increased risk of disease development: living in a shed during puppyhood, adoption at the age of 8-12 weeks and washing the dog regularly. In contrast, the following factors were associated with a lower risk: living in a rural environment, living in a household with other animals and walking in a forest. These associations do not prove causality but support the primary hypothesis that certain environmental factors may influence the development of canine atopic dermatitis. Further studies are warranted to confirm these results and conclusions. © 2011 The Authors. Veterinary Dermatology. © 2011 ESVD and ACVD.

The purpose of this study is to propose an instructional strategy that develop constructivist-constructionist learning environment that simultaneously develop chemistry knowledge and 21st century skills. Based on constructivist and constructionist learning theories, we identified three central guiding principles for this study: (1 engage students in discovery and problem solving task through teamwork, (2 provide opportunities for communicating ideas, and (3 involve students in the process of design. An intervention module, Malaysian Kimia (chemistry Digital Game known as MyKimDG, was developed as a mechanism for creating the learning environment. In this study, students were required to work collaboratively to design educational media that help their peers who face difficulty in learning particular concept. They were guided to go through the IDPCR (Inquiry, Discover, Produce, Communicate and Review phases. It is hypothesized that MyKimDG can create learning environment that allows students to deepen subject content knowledge and practice various 21st century skills in real situation. This study employed quasi-experimental study with non-equivalent control group pretest-posttest control group design. Results suggest that this approach is able to improve the acquisition of chemistry knowledge and high productivity skill.

    Full Text Available The article analyzes the development of small businesses at the national level through a comparative analysis between the former Soviet countries – Ukraine, Russia, Belarus, Kazakhstan, Uzbekistan, and Kyrgyzstan. These countries are comparable by the previous path dependence (the period of the USSR, communism, by the position of the geographical location, as well as by similarity of cultural development. As can be seen from the analysis, which was conducted in article, the quantitative characteristics of small business development in the above countries are similar, based on the dependence on foreign markets and conditions in national economies. However, qualitative indicators of small business development in these countries are different. These differences can be attributed to the activities of the institutional environment (formal and informal institutions and its impact on the national economy. Conclusions about the effectiveness of quality of development of small business sector through the analysis of its contribution to the national economy are done.

    Current instruments to evaluate the postgraduate medical educational environment lack theoretical frameworks and are relatively long, which may reduce response rates. We aimed to develop and validate a brief instrument that, based on a solid theoretical framework for educational environments, solicits resident feedback to screen the postgraduate medical educational environment quality. Stepwise, we developed a screening instrument, using existing instruments to assess educational environment quality and adopting a theoretical framework that defines three educational environment domains: content, atmosphere and organization. First, items from relevant existing instruments were collected and, after deleting duplicates and items not specifically addressing educational environment, grouped into the three domains. In a Delphi procedure, the item list was reduced to a set of items considered most important and comprehensively covering the three domains. These items were triangulated against the results of semi-structured interviews with 26 residents from three teaching hospitals to achieve face validity. This draft version of the Scan of Postgraduate Educational Environment Domains (SPEED) was administered to residents in a general and university hospital and further reduced and validated based on the data collected. Two hundred twenty-three residents completed the 43-item draft SPEED. We used half of the dataset for item reduction, and the other half for validating the resulting SPEED (15 items, 5 per domain). Internal consistencies were high. Correlations between domain scores in the draft and brief versions of SPEED were high (>0.85) and highly significant (ppostgraduate medical education.

    This paper describes the mechanical development of patch antenna arrays for the Juno mission. The patch arrays are part of a six-frequency microwave radiometer instrument that will be used to measure thermal emissions from Jupiter. The very harsh environmental conditions in Jupiter orbit, as well as a demanding launch environment, resulted in a design that departs radically from conventional printed circuit patch antennas. The paper discusses the development and qualification of the Juno patch array antennas, with emphasis on the materials approach that was devised to mitigate the effects of electron charging in Jupiter orbit.

    The development and testing of a measure evaluating the quality and variability in the home environment as it relates to the motor development of infants during the first year of life. A sample of 112 boys and 95 girls with a mean age of 7.1 months (SD 1.8) and GA of 39.6 weeks (SD 1.5) participated in the study. The measurement development process was divided into three phases: measurement development (item generation or selection of items from existing measurement tools), pilot testing to determine acceptability and feasibility to parents, and exploratory factor analysis to organize items into meaningful concepts. Test-retest reliability and internal consistency were also determined. The environmental opportunities questionnaire (EOQ) is a feasible 21-item measure comprised of three factors including opportunities in the play space, sensory variety and parental encouragement. Overall, test-retest reliability was 0.92 (CI 0.84-0.96) and the internal consistency is 0.79. The EOQ emphasizes quality of the environment and access to equipment and toys that have the potential to facilitate early motor development. The preliminary analyses reported here suggest more work could be done on the EOQ to strengthen its use for research or clinical purposes; however, it is adequate for use in its current form. Implications for Rehabilitation New and feasible 21-item questionnaire that enables identification of malleable environmental factors that serve as potential points of intervention for children that are not developing typically.

    As a result of the paradigm shift to a competency-based framework, both self-directed lifelong learning and learner-centeredness have become essential tenets of medical education. In the competency-based framework, learners drive their own educational process, and both learners and teachers share the responsibility for the path and content of learning. This learner-centered emphasis requires each physician to develop and maintain lifelong learning skills, which the authors propose culminate in becoming a "master leaner." To better understand the development of these skills and the attainment of that goal, the authors explore how learning theories inform the development of master learners and how to translate these theories into practical strategies for the learner, the teacher, and the learning environment so as to optimize this development.The authors begin by exploring self-determination theory, which lays the groundwork for understanding the motivation to learn. They next consider the theories of cognitive load and situated cognition, which inform the optimal context and environment for learning. Building from this foundation, the authors consider key educational theories that affect learners' abilities to serve as primary drivers of their learning, including self-directed learning (SDL); the self-assessment skills necessary for SDL; factors affecting self-assessment (self-concept, self-efficacy, illusory superiority, gap filling); and ways to mitigate the inaccuracies of self-assessment (reflection, self-monitoring, external information seeking, and self-directed assessment seeking).For each theory, they suggest practical action steps for the learner, the teacher, and the learning environment in an effort to provide a road map for developing master learners.

    2000-01-01

    Urban living is the keystone of modern human ecology. Cities have multiplied and expanded rapidly worldwide over the past two centuries. Cities are sources of creativity and technology, and they are the engines for economic growth. However, they are also sources of poverty, inequality, and health hazards from the environment. Urban populations have long been incubators and gateways for infectious diseases. The early industrializing period of unplanned growth and laissez-faire economic activity in cities in industrialized countries has been superseded by the rise of collective management of the urban environment. This occurred in response to environmental blight, increasing literacy, the development of democratic government, and the collective accrual of wealth. In many low-income countries, this process is being slowed by the pressures and priorities of economic globalization. Beyond the traditional risks of diarrhoeal disease and respiratory infections in the urban poor and the adaptation of various vector-borne infections to urbanization, the urban environment poses various physicochemical hazards. These include exposure to lead, air pollution, traffic hazards, and the "urban heat island" amplification of heatwaves. As the number of urban consumers and their material expectations rise and as the use of fossil fuels increases, cities contribute to the large-scale pressures on the biosphere including climate change. We must develop policies that ameliorate the existing, and usually unequally distributed, urban environmental health hazards and larger-scale environmental problems.

    1992-01-01

    Kolb's experiential learning theory (ELT) was used as a framework to study 179 generic baccalaureate students' perceptions of the contributions of different types of nursing learning environments to development of adaptive competencies described in the theory. In addition, students in each of the 4 years of the program were asked to describe their perceptions of the importance of Kolb's adaptive competencies for successful functioning in nursing settings as well as to rate their personal levels of skill on each competency. Nursing learning environments were thought to contribute most to divergent and convergent competencies, reflecting the importance of both people-oriented and scientific skills in nursing. Clinical experiences and the senior preceptorship experience contributed significantly more to the development of these competencies than typical nursing classes and nonnursing classes. Students considered assimilative competencies--such as testing theories--and ideas and accommodative competencies--such as leading and influencing others--relatively unimportant to successful functioning in nursing learning environments. Implications for nursing education are discussed.

    Enriched environment (EE) is characterized by improved conditions for enhanced exploration, cognitive activity, social interaction and physical exercise. It has been shown that EE positively regulates the remodeling of neural circuits, memory consolidation, long-term changes in synaptic strength and neurogenesis. However, the fine mechanisms by which environment shapes the brain at different postnatal developmental stages and the duration required to induce such changes are still a matter of debate. In EE, large groups of mice were housed in bigger cages and were given toys, nesting materials and other equipment that promote physical activity to provide a stimulating environment. Weaned mice were housed in EE for 4, 6 or 8 weeks and compared with matched control mice that were raised in a standard environment. To investigate the differential effects of EE on immature and mature brains, we also housed young adult mice (8 weeks old) for 4 weeks in EE. We studied the influence of onset and duration of EE housing on the structure and function of hippocampal neurons. We found that: (1) EE enhances neurogenesis in juvenile, but not young adult mice; (2) EE increases the number of synaptic contacts at every stage; (3) long-term potentiation (LTP) and spontaneous and miniature activity at the glutamatergic synapses are affected differently by EE depending on its onset and duration. Our study provides an integrative view of the role of EE during postnatal development in various mechanisms of plasticity in the hippocampus including neurogenesis, synaptic morphology and electrophysiological parameters of synaptic connectivity. This work provides an explanation for discrepancies found in the literature about the effects of EE on LTP and emphasizes the importance of environment on hippocampal plasticity.

    The potential use of fluorescent molecular probes to measure ions and biomolecules has contributed incessantly to the understanding of chemical and biological systems. The approach has many advantages such as high sensitivity, simplicity and non-destructive cellular imaging that offer visible information about the targeted species. In this article, our objective is to discuss fluorescent probes that have sensing applications within the mitochondrial environment. Mitochondria are cellular organelles which are well known for their unique physiological functions and have been found to be associated with various diseases and disorders. It is therefore, important to develop new tools and tactics that can provide useful information concerning the mitochondrial environment which in turn is essential to understand its biophysical functioning and related diseases.

    Vehicular Ad-hoc Networks (VANETs) is an area of wireless technologies that is attracting a great deal of interest. There are still several areas of VANETS, such as security and routing protocols, medium access control, that lack large amounts of research. There is also a lack of freely available simulators that can quickly and accurately simulate VANETs. The main goal of this paper is to develop a freely available VANETS simulator and to evaluate popular mobile ad-hoc network routing protocols in several VANETS scenarios. The VANETS simulator consisted of a network simulator, traffic (mobility simulator) and used a client-server application to keep the two simulators in sync. The VANETS simulator also models buildings to create a more realistic wireless network environment. Ad-Hoc Distance Vector routing (AODV), Dynamic Source Routing (DSR) and Dynamic MANET On-demand (DYMO) were initially simulated in a city, country, and highway environment to provide an overall evaluation.

    2000-01-01

    Full Text Available Interaction among actors involved in a Web-based learning environment is widely thought of as a valuable process, in that it stimulates collaborative work and augments the effectiveness of learning itself. This may be extensively achieved by the integration of groupware tools and techniques, originally coming from the Computer-Supported Cooperative Work discipline. This paper reports on MEDIT, a Web-based environment that addresses various pedagogical issues and has been developed in line with the above. Offering complementary support, and not substituting traditional practices, our approach distinguishes three virtual workspaces and provides appropriate services for each of them. The paper focuses on the presentation of the innovative tools MEDIT is composed of. These concern the multiple view representation of a course, the creation and maintenance of student customised courses, several exercise methods, argumentative discourse between teachers and students, and group decision making. MEDIT has already been used in five undergraduate courses demonstrating promising evaluation results.

    2016-04-01

    Full Text Available This paper deals with fuzzy goal programming approach to solve fuzzy linear bilevel integer programming problems with fuzzy probabilistic constraints following Pareto distribution and Frechet distribution. In the proposed approach a new chance constrained programming methodology is developed from the view point of managing those probabilistic constraints in a hybrid fuzzy environment. A method of defuzzification of fuzzy numbers using ?-cut has been adopted to reduce the problem into a linear bilevel integer programming problem. The individual optimal value of the objective of each DM is found in isolation to construct the fuzzy membership goals. Finally, fuzzy goal programming approach is used to achieve maximum degree of each of the membership goals by minimizing under deviational variables in the decision making environment. To demonstrate the efficiency of the proposed approach, a numerical example is provided.

    2014-01-01

    A High Temperature Fiber Optic Sensor (HTFOS) has been developed at NASA Glenn Research Center for aircraft engine applications. After fabrication and preliminary in-house performance evaluation, the HTFOS was tested in an engine environment at NASA Armstrong Flight Research Center. The engine tests enabled the performance of the HTFOS in real engine environments to be evaluated along with the ability of the sensor to respond to changes in the engine's operating condition. Data were collected prior, during, and after each test in order to observe the change in temperature from ambient to each of the various test point levels. An adequate amount of data was collected and analyzed to satisfy the research team that HTFOS operates properly while the engine was running. Temperature measurements made by HTFOS while the engine was running agreed with those anticipated.

    Full Text Available Objective: To assess the effect of aquatic environment while an occupational therapeutic scenario in the development of body scheme of a child with Down Syndrome, considering the therapeutic properties of water. Description of the case: An interventionist research, with a qualitative and descriptive approach, conducted in an adapted pool of the Núcleo de Atenção Médica Integrada (NAMI of Fortaleza University (UNIFOR, Ceara, during the period of March to May, 2005. The subject of the study was a female child, aged 10 years old, diagnosed with Down Syndrome. Data collection had as instruments an interview guide for anamnesis, an evaluation form of psychomotor development, besides a field diary to record clinical observations during the sessions. This information was organized and analyzed based on clinical reasoning of occupational therapists and then described as a case study. We observed an evolution in the development of skills related to body scheme, such as the perception of fine parts of her own body, as well as large parts in someone else’s body, the imitation of positions, finishing with more active participation in activities of daily living. Final Considerations: We verified the effectiveness of occupational therapeutic activities conducted in aquatic environment for the development of the body scheme of the child in the study. This may be useful for conducting further research on the subject – whose literature is scarce – and contributing to the crescent update of occupational therapy practices.

    2013-04-01

    Computational multiscale models help cancer biologists to study the spatiotemporal dynamics of complex biological systems and to reveal the underlying mechanism of emergent properties. To facilitate the construction of such models, we have developed a next generation modelling platform for cancer systems biology, termed 'ELECANS' (electronic cancer system). It is equipped with a graphical user interface-based development environment for multiscale modelling along with a software development kit such that hierarchically complex biological systems can be conveniently modelled and simulated by using the graphical user interface/software development kit combination. Associated software accessories can also help users to perform post-processing of the simulation data for visualization and further analysis. In summary, ELECANS is a new modelling platform for cancer systems biology and provides a convenient and flexible modelling and simulation environment that is particularly useful for those without an intensive programming background. ELECANS, its associated software accessories, demo examples, documentation and issues database are freely available at http://sbie.kaist.ac.kr/sub_0204.php. Supplementary data are available at Bioinformatics online.

    2012-12-01

    Full Text Available The purpose of this paper is to contribute to learning, knowledge creation and knowledge transfer for building organization innovability by integrating the management systems in the SIMPRO-IMS web based environment. The paper content consists of the interpretation of role-play simulation, role-play simulation process description, methodology, and the employment of role-play simulation outcomes, as well as the discussion of the knowledge thus obtained. Primary the model of the SIMPRO-Q education environment has been developed and tested during a period of 15 years in several industrial organizations as well as service organizations such as Higher Education Institution (HEI and Healthcare Organization (HCO. The newest version SIMPRO-IMS has recently been developed to support a need of integration of management systems and information archiving. With the last development, SIMPRO-IMS web based environment, processes of five ISO systems are integrated for parallel development, implementation, auditing, maintaining and leading. SIMPRO-IMS provides management with the apparatus necessary to realize a systematic and verifiable approach to the creation and control of IMS documentation. At the same time contributes to the preservation of organization memory in response to the growing challenges of globalization and digitalization. The research is limited by the complexity of a real system and possible empiric results verification. The results achieved are verified when people really overcome the resistance to change. This can be assessed thoughtfully only after some period of time. Another limitation is presented by measurability of real enhancement achieved in quality, safety and environmentality of production, and business continuity and social responsibility of an organization. Development and progress in the methodology of SIMPRO-IMS web based environment is encoded in upgrading the SIMPRO database by processes of the environmental management

  20. An EXTrauterine environment for neonatal development: EXTENDING fetal physiology beyond the womb.

    2017-12-01

    Extreme prematurity is a major cause of neonatal mortality and morbidity, and remains an unsolved clinical challenge. The development of an artificial womb, an extrauterine system recreating the intrauterine environment, would support ongoing growth and organ maturation of the extreme preterm fetus and would have the potential to substantially improve survival and reduce morbidity. Previous efforts toward the development of such a system have demonstrated the ability to maintain the isolated fetus for short periods of support, but have failed to achieve the long-term stability required for clinical application. Here we describe our initial experiments demonstrating the stable support of fetal lambs developmentally equivalent to the extreme premature infant for up to four weeks with stable hemodynamics, growth, and development. The achievement of long-term physiologic support of the fetus in an extrauterine system has the potential to fundamentally change the management and clinical outcome of the extreme premature infant.

    2017-08-01

    The present study aimed to develop and validate a questionnaire assessing perceived food environment in a French-Canadian population. A questionnaire, the Perceived Food Environment Questionnaire, was developed assessing perceived accessibility to healthy (nine items) and unhealthy foods (three items). A pre-test sample was recruited for a pilot testing of the questionnaire. For the validation study, another sample was recruited and completed the questionnaire twice. Exploratory factor analysis was performed on the items to assess the number of factors (subscales). Cronbach's α was used to measure internal consistency reliability. Test-retest reliability was assessed with Pearson correlations. Online survey. Men and women from the Québec City area (n 31 in the pre-test sample; n 150 in the validation study sample). The pilot testing did not lead to any change in the questionnaire. The exploratory factor analysis revealed a two-subscale structure. The first subscale is composed of six items assessing accessibility to healthy foods and the second includes three items related to accessibility to unhealthy foods. Three items were removed from the questionnaire due to low loading on the two subscales. The subscales demonstrated adequate internal consistency (Cronbach's α=0·77 for healthy foods and 0·62 for unhealthy foods) and test-retest reliability (r=0·59 and 0·60, respectively; both P<0·0001). The Perceived Food Environment Questionnaire was developed for a French-Canadian population and demonstrated good psychometric properties. Further validation is recommended if the questionnaire is to be used in other populations.

    Social anxiety disorder (SAD) is a very common condition, although its prevalence is believed to be underestimated. The affected subjects often have trouble to search for support. The onset occurs mainly in early adolescence. The aim of this paper was to evaluate the impact of school and family background on the development of SAD. Our survey, available on a popular social network site, was divided into 4 parts: 1) demographic data (gender, age, site of residence), 2) genetic and organic background (comorbid mental disorders, addictions), 3) situation at school and in the family environment during adolescence, 4) the part designed to define the group that may suffer from SAD with the use of the Mini-Social Phobia Inventory (Mini-SPIN). 226 people were recruited. The age range was 16-61, with the average of 25,8. 71% of the respondents lived in cities with a population of more than 100 000. Male to female ratio was 3:1. According to Mini-SPIN 26,5% of the interviewees might suffer from SAD (28.2% of women and 21.4% of men). Our study showed, that both family and school environment factors have an influence on the development of SAD. It was shown that the especially important risk factors are bad relations with peers and being an object of derision at school. The percentage of network community users that are likely to suffer from SAD, significantly exceeds the clinical data. Both family and school environment factors were shown to be risk factors for the development of this disorder.

    The postnatal environment, including factors such as weaning and acquisition of the gut microbiota, has been causally linked to the development of later immunological diseases such as allergy and autoimmunity, and has also been associated with a predisposition to metabolic disorders. We show that the very early-life environment influences the development of both the gut microbiota and host metabolic phenotype in a porcine model of human infants. Farm piglets were nursed by their mothers for 1 day, before removal to highly controlled, individual isolators where they received formula milk until weaning at 21 days. The experiment was repeated, to create two batches, which differed only in minor environmental fluctuations during the first day. At day 1 after birth, metabolic profiling of serum by (1)H nuclear magnetic resonance spectroscopy demonstrated significant, systemic, inter-batch variation which persisted until weaning. However, the urinary metabolic profiles demonstrated that significant inter-batch effects on 3-hydroxyisovalerate, trimethylamine-N-oxide and mannitol persisted beyond weaning to at least 35 days. Batch effects were linked to significant differences in the composition of colonic microbiota at 35 days, determined by 16 S pyrosequencing. Different weaning diets modulated both the microbiota and metabolic phenotype independently of the persistent batch effects. We demonstrate that the environment during the first day of life influences development of the microbiota and metabolic phenotype and thus should be taken into account when interrogating experimental outcomes. In addition, we suggest that intervention at this early time could provide 'metabolic rescue' for at-risk infants who have undergone aberrant patterns of initial intestinal colonisation.

  4. The Investment Environment for Renewable Energy Development in Lithuania: The Electricity Sector

    Directory of Open Access Journals (Sweden)

    Milčiuvienė Saulė

    2014-06-01

    Full Text Available The article analyzes the investment environment in renewable electricity generation capacities, evaluating the credibility of long term renewable energy targets, the stability of promotion schemes and the impartiality of national administrative procedure. The article explores two main questions: (i are the EU and Lithuanian energy policy targets and promotion schemes credible enough to convince private investors to put their money in renewable energy development; (ii does national administrative procedure put a disproportional burden on renewable energy investors or on certain group of investors? The assessment of the investment environment includes a large number of criteria, but we analyze three of them: the stability of long term strategy; the attractiveness of promotionmeasures; and the simplicity and transparency of administrative procedure. Two further criteria are investigated: the stability of targets in renewable energy and the stability of promotional measures. The greatest uncertainty for investors occurs because of constantly changing support schemes of renewable energy sources-schemes that are not harmonized among the member States. At the national level the main driver in the development of small generators is the feed-in tariff. However, the high feed-in tariff does not always guarantee the smooth development of small scale generators of renewable energy.

  5. Connecting cities and their environments: Harnessing the water-energy-food nexus for sustainable urban development

    Directory of Open Access Journals (Sweden)

    Chan Arthur

    2015-01-01

    Full Text Available Thousands of years of development have made the production and consumption of water, energy, and food for urban environments more complex. While the rise of cities has fostered social and economic progress, the accompanying environmental pressures threaten to undermine these benefits. The compounding effects of climate change, habitat loss, pollution, overexploitation (in addition to financial constraints make the individual management of these three vital resources incompatible with rapidly growing populations and resource-intensive lifestyles. Nexus thinking is a critical tool to capture opportunities for urban sustainability in both industrialised and developing cities. A nexus approach to water, energy, and food security recognises that conventional decisionmaking, strictly confined within distinct sectors, limits the sustainability of urban development. Important nexus considerations include the need to collaborate with a wide spectrum of stakeholders, and to “re-integrate” urban systems. This means recognising the opportunities coming from the interconnected nature of cities and metropolitan regions, including links with rural environments and wider biophysical dynamics.

    Exotic dancers have received little research attention despite evidence of high-risk behaviours within exotic dance clubs (EDCs). We developed and assessed the reliability and validity of a risk environment score, examining differences between dancers (n = 107) and other staff (n = 172). In the summer of 2013, anonymous surveys were administered via A-CASI in EDCs (N = 26) in Baltimore among exotic dancers and staff. Surveys consisted of a brief demographic section followed by 65 statements. The overall domain had an alpha = 0.77 and subdomains had the following: social (alpha = 0.87), economic (alpha = 0.92), drug (alpha = 0.89), and policy (alpha = 0.66). In a factor analysis, each domain contributed significantly to the overall latent construct. The results indicate a high level of HIV/STI risk for dancers in EDCs and underscore the need for targeted interventions in these environments. As we continue to unpack the function of the broader environment in STI/HIV risk transmission, the scale could be instructive for other settings.

    2010-10-01

    Track and field includes a number of high-intensity disciplines with many demanding practices and represents a motivational challenge for talented athletes aiming to make a successful transition to the senior elite level. Based on a holistic ecological approach, this study presents an analysis of a particular athletic talent development environment, the IFK Växjö track and field club, and examines key factors behind its successful history of creating top-level athletes. The research takes the form of a case study. Data were collected from multiple perspectives (in-depth interviews with administrators, coaches and athletes), from multiple situations (observation of training, competitions and meetings) and from the analysis of documents. The environment was characterized by a high degree of cohesion, by the organization of athletes and coaches into groups and teams, and by the important role given to elite athletes. A strong organizational culture, characterized by values of open co-operation, by a focus on performance process and by a whole-person approach, provided an important basis for the environment's success. The holistic ecological approach encourages practitioners to broaden their focus beyond the individual in their efforts to help talented junior athletes make a successful transition to the elite senior level. © 2010 John Wiley & Sons A/S.

    Full Text Available Pedestrians, comprising approximately 60% of the population, are among the most vulnerable road users in South Africa. The roadside environment may be an important factor influencing the nature and frequency of pedestrian fatalities. While there are audit tools for assessing the pedestrian environment in other countries, no such tool exists for South Africa. This study evaluated existing audit tools in relation to South African issues and conditions and developed a South African Pedestrian Environment Assessment Tool (PEAT. PEAT was tested at five sites in the Tshwane Metropolitan Area in Gauteng to assess its applicability. PEAT was simple to use and provided valuable information, however, appropriate measures need to be taken to address fieldworker security, especially for night-time assessments when several roadside factors, such as lighting, should be evaluated. Although it was not the focus of our study, based on our results, we suggest that the lack of pavements, pedestrian crossings and pedestrian lighting are factors that, potentially, could increase pedestrian vulnerability.

  9. A Development of Game-Based Learning Environment to Activate Interaction among Learners

    Takaoka, Ryo; Shimokawa, Masayuki; Okamoto, Toshio

    Many studies and systems that incorporate elements such as “pleasure” and “fun” in the game to improve a learner's motivation have been developed in the field of learning environments. However, few are the studies of situations where many learners gather at a single computer and participate in a game-based learning environment (GBLE), and where the GBLE designs the learning process by controlling the interactions between learners such as competition, collaboration, and learning by teaching. Therefore, the purpose of this study is to propose a framework of educational control that induces and activates interaction between learners intentionally to create a learning opportunity that is based on the knowledge understanding model of each learner. In this paper, we explain the design philosophy and the framework of our GBLE called “Who becomes the king in the country of mathematics?” from a game viewpoint and describe the method of learning support control in the learning environment. In addition, we report the results of the learning experiment with our GBLE, which we carried out in a junior high school, and include some comments by a principal and a teacher. From the results of the experiment and some comments, we noticed that a game may play a significant role in weakening the learning relationship among students and creating new relationships in the world of the game. Furthermore, we discovered that learning support control of the GBLE has led to activation of the interaction between learners to some extent.

  10. Development of a Survivable Cloud Multi-Robot Framework for Heterogeneous Environments

    2014-10-01

    Full Text Available Cloud robotics is a paradigm that allows for robots to offload computationally intensive and data storage requirements into the cloud by providing a secure and customizable environment. The challenge for cloud robotics is the inherent problem of cloud disconnection. A major assumption made in the development of the current cloud robotics frameworks is that the connection between the cloud and the robot is always available. However, for multi-robots working in heterogeneous environments, the connection between the cloud and the robots cannot always be guaranteed. This work serves to assist with the challenge of disconnection in cloud robotics by proposing a survivable cloud multi-robotics (SCMR framework for heterogeneous environments. The SCMR framework leverages the combination of a virtual ad hoc network formed by robot-to-robot communication and a physical cloud infrastructure formed by robot-to-cloud communications. The quality of service (QoS on the SCMR framework was tested and validated by determining the optimal energy utilization and time of response (ToR on drivability analysis with and without cloud connection. The design trade-off, including the result, is between the computation energy for the robot execution and the offloading energy for the cloud execution.

    To explore and develop three-dimension (3D) virtual reality (VR) liver model and convert computed tomography data into a fully 3D VR environment for display, measure and manipulation. 3D-reconstruction of liver was restored from spiral computed tomography (CT) data by using LiVirtue software. Dextrobeam was used to view the 3D model in the VR environment. The liver and its anatomic structure were reconstructed to illuminate the location of the tumor and its related vessels. 3D models of liver, tumor and their relative vessels were reconstructed successfully. These models could be viewed and manipulated in the VR environment on personal computer.38 patients underwent liver resection, including 21 right hemihepatectomy, 14 left hemihepatectomy and 3 extended right hemihepatectomy. The intraoperative contrast with preoperative simulation confirmed the reliability of our 3D operative planning system. The preoperative simulation in 3D VR facilitated liver resection by the ability to view tumor and its relative vessels. This preoperative estimation from 3D model of liver benefits a lot to complicated liver resection.

    Full Text Available The corrosion resistance of any metallic material depends on the environment to which it is exposed. DMR-1700 steel is a material for structural applications that has been recently developed at Defence Metallurgical Research Laboratory by changing the chemistry of alloying elements. Therefore, a detailed understanding of its corrosion characteristics under different environmental conditions is essential. In the present paper, we report the results of a systematic corrosion study that was carried out on the new steel to determine the effect of the environment on the protective nature of the oxide scale that forms on its surface under different environmental conditions. Furthermore, the oxide scale as well as the resistance to pitting and crevice corrosion were studied in various environments. The surface morphologies of the corroded steels were observed under a scanning electron microscope (SEM to determine the nature of the corrosion. On the basis of studies by different techniques, DMR-1700 steel is recommended for the manufacture of components used in various systems in conjunction with the application of an appropriate protective coating to improve its resistivity to corrosion.

    Full Text Available In this study, we show the effectiveness of a virtual environment comprising 18 computer games that cover mathematics topics in a playful setting and that can be executed on the Internet with the possibility of player interaction through chat. An arithmetic pre-test contained in the Scholastic Performance Test was administered to 300 children between 7 and 10 years old, including 162 males and 138 females, in the second grade of primary school. Twenty-six children whose scores showed a low level of mathematical knowledge were chosen and randomly divided into the control (CG and experimental (EG groups. The EG participated to the virtual environment and the CG participated in reinforcement using traditional teaching methods. Both groups took a post-test in which the Scholastic Performance Test (SPT was given again. A statistical analysis of the results using the Student's t-test showed a significant learning improvement for the EG and no improvement for the CG (p≤0.05. The virtual environment allows the students to integrate thought, feeling and action, thus motivating the children to learn and contributing to their intellectual development.

    Hikosaka, Tomoyuki; Yamazaki, Akina; Hatta, Yasunori; Koide, Hidenobu; Kanoh, Takaaki; Suzuki, Takashi; Yamada, Junichi; Uemura, Shingo

    We have developed a new environment-conscious transformer impregnated with vegetable based insulating oil which called PFAE (Palm Fatty Acid Ester). PFAE has 0.6 times less viscosity and 1.3 times higher dielectric constant compared to mineral oil. This means that a PFAE immersed transformer has better cooling efficiency and better insulating performance in paper-and-oil composite insulation systems, resulting in size reduction in comparison to conventional mineral oil immersed transformers. In this paper, insulating performance of lead to plane electrode models, cooling performance of a PFAE immersed transformer, and the result of analytical study of dissolved gas for abnormal diagnosis are described.

    Assessment environment, synonymous with climate or atmosphere, is multifaceted. Although there are valid and reliable instruments for measuring the educational environment, there is no validated instrument for measuring the assessment environment in medical programs. This study aimed to develop an instrument for measuring students' perceptions of the assessment environment in an undergraduate medical program and to examine the psychometric properties of the new instrument. The Assessment Environment Questionnaire (AEQ), a 40-item, four-point (1=Strongly Disagree to 4=Strongly Agree) Likert scale instrument designed by the authors, was administered to medical undergraduates from the authors' institution. The response rate was 626/794 (78.84%). To establish construct validity, exploratory factor analysis (EFA) with principal component analysis and varimax rotation was conducted. To examine the internal consistency reliability of the instrument, Cronbach's α was computed. Mean scores for the entire AEQ and for each factor/subscale were calculated. Mean AEQ scores of students from different academic years and sex were examined. Six hundred and eleven completed questionnaires were analysed. EFA extracted four factors: feedback mechanism (seven items), learning and performance (five items), information on assessment (five items), and assessment system/procedure (three items), which together explained 56.72% of the variance. Based on the four extracted factors/subscales, the AEQ was reduced to 20 items. Cronbach's α for the 20-item AEQ was 0.89, whereas Cronbach's α for the four factors/subscales ranged from 0.71 to 0.87. Mean score for the AEQ was 2.68/4.00. The factor/subscale of 'feedback mechanism' recorded the lowest mean (2.39/4.00), whereas the factor/subscale of 'assessment system/procedure' scored the highest mean (2.92/4.00). Significant differences were found among the AEQ scores of students from different academic years. The AEQ is a valid and reliable

    The word "ESD (Education for Sustainable Development)" has spread over the world in UN decade (2005 - 2014), and the momentum of the educational innovation aimed at ESD also has grown in the world. Especially, environmental educations recognized as one of the most important ESD have developed in many countries including Japan, but most of those are still mainly experiences in nature. Those could develop "Respect for Environment" of the educational targets of ESD, however we would have to take a further step in order to enhance "Ability of analysis and thinking logically about the environment" which are also targets of ESD.Thus, we developed experienced-learning program about atmospheric particulate matter (PM2.5), for understanding the state of the environment objectively based on quantitative data. PM2.5 is known for harmful, and various human activities are considered a source of it, therefore environmental standards for PM2.5 have been established in many countries. This program was tested on junior high school students of 13 - 15 years old, and the questionnaire survey also was conducted to them before and after the program for evaluating educational effects. Students experienced to measure the concentration of PM2.5 at 5 places around their school in a practical manner. The measured concentration of PM2.5 ranged from 19 to 41 μg/m3/day, that value at the most crowded roadside exceeded Japan's environmental standard (35 μg/m3/day). Many of them expressed "Value of PM2.5 is high" in their individual discussion notes. As a consistent with that, the answer "Don't know" to the question "What do you think about the state of the air?" markedly decreased after the program, on the other hand the answer "Pollution" to the same question increased instead. From above-mentioned, it was considered that they could judge the state of the air objectively. Consequently, the questionnaire result "Concern about Air Pollution" increased significantly after the program compared

  5. Development of a GUI based RETRAN running environment for Kori NPP units 1 and 2

    2000-09-01

    RETRAN was developed by EPRI and introduced for domestic use. RETRAN, which is a best-estimate system code approved by USNRC and used by most utilities in US, can be used in various plant support activities such as licensing calculations for plant design changes, EOP validation, and training. RETRAN, however, has been limited to only a few groups of specialists because of the difficulty involved in its usage. The aim of this project is to develop a graphic user interface (GUI) based code running environment for RETRAN named PRE (RETRAN Running Environment) in order to assist ordinary users in their input preparation, code execution, and output interpretation. TRIP and CONTROL BLOCK and VOLUME/JUNCTION input cards from base input are designed to be able to modify the existing input cards and add a new input cards through dialog boxes for users who have not much expertise in use of RETRAN. The RRE is designed to provide the calculated results though on-line X-Y graphs, plant mimics, indicators, nodalization window for easy interpretation of its output. It also provides the replay function using pre-calculated results saved in files. The RRE was developed for Kori NPP units 1 and 2 using Delphi 4.0 and Visual Fortran 6.0 and it runs on personal computers to increase the accessibility. The RRE developed in this study for Kori units 1 and 2 can be used in various plant support activities which require thermal-hydraulic analysis of the NSSS (Nuclear Steam Supply System) such as licensing calculations for plant design change, validation of EOP improvement, and operator training. The RRE developed can be expanded its application to other nuclear plants with low expense.

  6. Decoupling reconsidered: Does world society integration influence the relationship between the environment and economic development?

    2017-07-01

    This study advances scholarship on environment and development by examining whether nations more embedded in the pro-environmental world society are more or less likely to experience a relative decoupling between economic development and carbon emissions over time. The authors calculate a network centrality measure using national-level membership data on environmental international nongovernmental organizations (INGOs), and then employ the measure to create four subsamples of nations that are relatively more or less integrated in the environmental world society. The authors use interactions between measures of economic development and time in two-way fixed effects models to estimate the potentially changing effects of development on carbon emissions for the four subsamples of nations from 1970 to 2009. Results indicate that nations that are the most embedded in the environmental world society experienced a moderate decrease through time in the effect of development on carbon emissions, while the effect of development on emissions increased through time in the most peripheral nations.

    The Heat shield for Extreme Entry Environment Technology (HEEET) Project is a NASA STMD and SMD co-funded effort. The goal is to develop and mission infuse a new ablative Thermal Protection System that can withstand extreme entry. It is targeted to support NASA's high priority missions, as defined in the latest decadal survey, to destinations such as Venus and Saturn in-situ robotic science missions. Entry into these planetary atmospheres results in extreme heating. The entry peak heat-flux and associated pressure are estimated to be between one and two orders of magnitude higher than those experienced by Mars Science Laboratory or Lunar return missions. In the recent New Frontiers community announcement NASA has indicated that it is considering providing an increase to the PI managed mission cost (PIMMC) for investigations utilizing the Heat Shield for Extreme Entry Environment Technology (HEEET) and in addition, NASA is considering limiting the risk assessment to only their accommodation on the spacecraft and the mission environment. The HEEET ablative TPS utilizes 3D weaving technology to manufacture a dual layer material architecture. The 3-D weaving allows for flat panels to be woven. The dual layer consists of a top layer designed to withstand the extreme external environment while the inner or insulating layer by design, is designed to achieve low thermal conductivity, and it keeps the heat from conducting towards the structure underneath. Both arc jet testing combined with material properties have been used to develop thermal response models that allows for comparison of performance with heritage carbon phenolic. A 50% mass efficiency is achieved by the dual layer construct compared to carbon phenolic for a broad range of missions both to Saturn and Venus. The 3-D woven flat preforms are molded to achieve the shape as they are compliant and then resin infusion with curing forms a rigid panels. These panels are then bonded on to the aeroshell structure.

  8. Effect of Altered Gravity Environment on Tobacco Hornworm (Manduca Sexta) Development

    Tischler, Marc E.

    1996-01-01

    Metamorphosis provides a unique condition for studying the role of gravity in development. Formation of new organs in a previously existing organism requires a highly active period of turnover of amino acids and proteins, and of changes in the endocrine profile. Furthermore, metamorphosis offers the advantage of studying a self-contained biological system. The tobacco hornworm provides a suitable species to study the effect of altered gravitational environment on invertebrate development. This species has been one of the most thoroughly investigated organisms in a variety of aspects of insect biology. M. sexta pharate adults can provide significant amounts of material with which to work, thus facilitating the study of metabolic aspects of adult development. During wandering, the period immediately following cessation of larval feeding, the larva burrows into the soil to form a pupation chamber. Despite burrowing down 25 to 30 cm, the insects reorient themselves to a slightly head-up (10 +/- 1 degree) position. Since light and temperature are not factors in this process, the larvae must sense the gravity vector. In our ground-based studies we had assessed whether developing adults might be sensitive to their gravitational environment by orienting pupae in a vertical head-up position within 24 to 48 h after pupal ecdysis. Our ground-based findings formed the foundation for determining which parameters would be evaluated in developing Manduca following spaceflight. Measurements were to include: (1) extent of development by all of the insects, (2) analysis of hemolymph obtained from half of the insects postflight for ecdysteroid, amino acid, urea, ammonia and trehalose concentrations, (3) further development of the other half of the insects to adult (moths), (4) analysis of the flight muscle protein content of the adults. Based on the first flight attempt in July, 1995, we modified the BRIC hardware to accommodate the insects. Our studies after BRIC-04 showed that

    The author has recently been awarded the NSF Career award to develop a radar with cognitive sensing capabilities to study Equatorial plasma instabilities in the Peruvian Andes. Educational research has shown that a rich learning environment contributes tremendously toward improvement in learning achievements and also attitudes toward studies. One of the benefits of this project is that it provides such an environment and a global platform to involve several students at both graduate and undergraduate levels from the US, Puerto Rico, and Peru, and who will benefit from designing, installing, and deploying a radar in multi-instrument science campaigns. In addition to working in the laboratories, students will gain invaluable real world experience building this complex instrument and making it work under challenging conditions at remote sites. The PI will describe how these components are being developed in a Freshman Seminar course and Graduate courses in the Department of Electrical Engineering at Penn State University, and how they are aligned well with the department's and university's strategy for greater global engagement through a network of Global Engagement Nodes in South America (GENSA). The issues of mentoring, recruitment, and retention become particularly important in consideration of the educational objective of this career project to involve underrepresented students with diverse backgrounds and interest them in research projects. The author is working very closely with the Office of Engineering Diversity to leverage existing programs at Penn State designed to increase the participation of women and minority students in science and engineering research: (a) WISER (Women In Science and Engineering Research), and (b) MURE (Minority Undergraduate Research Experience). The Electrical Engineering Department at Penn State is also currently an NSF REU (Research Experience for Undergraduates) site. The PI will also present his efforts in connecting his career

  10. From Millennium Development Goals to post-2015 sustainable development: sexual and reproductive health and rights in an evolving aid environment.

    2013-11-01

    Using research from country case studies, this paper offers insights into the range of institutional and structural changes in development assistance between 2005 and 2011, and their impact on the inclusion of a sexual and reproductive health and rights agenda in national planning environments. At a global level during this period, donors supported more integrative modalities of aid - sector wide approaches, poverty reduction strategy papers, direct budgetary support - with greater use of economic frameworks in decision-making. The Millennium Development Goals brought heightened attention to maternal mortality, but at the expense of a broader sexual and reproductive health and rights agenda. Advocacy at the national planning level was not well linked to programme implementation; health officials were disadvantaged in economic arguments, and lacked financial and budgetary controls to ensure a connection between advocacy and action. With increasing competency in higher level planning processes, health officials are now refocusing the post-2015 development goals. If sexual and reproductive health and rights is to claim engagement across all its multiple elements, advocates need to link them to the key themes of sustainable development: inequalities in gender, education, growth and population, but also to urbanisation, migration, women in employment and climate change.

    2012-02-01

    Assessment of land resources carrying capacity is the key point of planning environment impact assessment and the main foundation to determine whether the planning could be implemented or not. With the help of the space analysis function of Geographic Information System, and selecting altitude, slope, land use type, distance from resident land, distance from main traffic roads, and distance from environmentally sensitive area as the sensitive factors, a comprehensive assessment on the ecological sensitivity and its spatial distribution in Zhangzhou Merchants Economic and Technological Development Zone, Fujian Province of East China was conducted, and the assessment results were combined with the planning land layout diagram for the ecological suitability analysis. In the Development Zone, 84.0% of resident land, 93.1% of industrial land, 86.0% of traffic land, and 76. 0% of other constructive lands in planning were located in insensitive and gently sensitive areas, and thus, the implement of the land use planning generally had little impact on the ecological environment, and the land resources in the planning area was able to meet the land use demand. The assessment of the population carrying capacity with ecological land as the limiting factor indicated that in considering the highly sensitive area and 60% of the moderately sensitive area as ecological land, the population within the Zone in the planning could reach 240000, and the available land area per capita could be 134.0 m2. Such a planned population scale is appropriate, according to the related standards of constructive land.

  14. International trade in biofuels: Good for development? And good for Environment?

    Energy Technology Data Exchange (ETDEWEB)

    Dufey, Annie

    2007-01-15

    Biofuels are heating up debates and energising activities on many policy fronts. On the surface, they offer significant opportunities to pursue environment and development goals both globally and domestically. There are both synergies and trade-offs between these goals and levels. Trade will drive biofuels growth, yet current trade regimes are not fit for maximising benefits nor minimising risks from the sector. The novelty of biofuels, the vast array of issues involved and the lack of knowledge to tackle many of them, together with diverging political and business interests, mean that consensus is elusive. It is therefore increasingly urgent to map a path for the global biofuels industry that supports sustainable development. Based on a new analysis of the sector, this briefing lays out some of the options for achieving this.

    The built environment stocks such as buildings and infrastructures are key to human development: they provide the fundamental physical settings that the provision of basic human needs such as food, shelter, and transport rely on, but also contribute to anthropogenic greenhouse gas (GHG) emissions...... throughout their construction, operation, and end-of-life management phases. These stocks usually exist in societies for relatively long time, from years to over a century, therefore their dynamics have long term impacts on human development and emission growth. Several recent studies, including the Fifth......

However, there is still a lack of quantitative analysis and evidence to support this claim. Here, based on an empirical regression model and a new...

  16. The Challenge of Grounding Planning in Simulation with an Interactive Model Development Environment

    A principal obstacle to fielding automated planning systems is the difficulty of modeling. Physical systems are modeled conventionally based on specification documents and the modeler's understanding of the system. Thus, the model is developed in a way that is disconnected from the system's actual behavior and is vulnerable to manual error. Another obstacle to fielding planners is testing and validation. For a space mission, generated plans must be validated often by translating them into command sequences that are run in a simulation testbed. Testing in this way is complex and onerous because of the large number of possible plans and states of the spacecraft. Though, if used as a source of domain knowledge, the simulator can ease validation. This paper poses a challenge: to ground planning models in the system physics represented by simulation. A proposed, interactive model development environment illustrates the integration of planning and simulation to meet the challenge. This integration reveals research paths for automated model construction and validation.

    Fracture behavior and fracture toughness are of great interest regarding reliability of hydrogen pipelines and storage tanks, however, many conventional fracture testing techniques are difficult to be realized under the presence of hydrogen, in addition to the inherited specimen size effect. Thus it is desired to develop novel in situ fracture toughness evaluation techniques to study the fracture behavior of structural materials in hydrogen environments. In this study, a torsional fixture was developed to utilize an emerging fracture testing technique, Spiral Notch Torsion Test (SNTT). The in situ testing results indicated that the exposure to H2 significantly reduces the fracture toughness of 4340 high strength steels by up to 50 percent. Furthermore, SNTT tests conducted in air demonstrated a significant fracture toughness reduction in samples subject to simulated welding heat treatment using Gleeble, which illustrated the effect of welding on the fracture toughness of this material.

    Full Text Available The manner that young people and adults are communicating with each other is rapidly changing in society that is, in part, driven by the latest technology. As a youth-driven program, we must engage in new strategies and methods by which we communicate with youth members, volunteers, families, and the community at large. Social and mobile media are a growing and popular venue for much of our target audience and youth development practitioners must learn how to leverage these networks to create positive youth development in online environments. If we ignore and don’t engage in the opportunity to be connected to youth online, then youth are left to make their own paths online and set the online norms. As youth organizations, we also must seize the opportunity to be online mentors and use the resources that are available and being used by our target populations.

    Reducing size and weight of spacecraft, along with demanding increased performance capabilities, introduces many uncertainties in the engineering design community on how materials and spacecraft systems will perform in space. The engineering design community is forever behind on obtaining and developing new tools and guidelines to mitigate the harmful effects of the space environment. Adding to this complexity is the continued push to use Commercial-off-the-Shelf (COTS) microelectronics, potential usage of unproven technologies such as large solar sail structures and nuclear electric propulsion. In order to drive down these uncertainties, various programs are working together to avoid duplication, save what resources are available in this technical area and possess a focused agenda to insert these new developments into future mission designs. This paper will introduce the SEE Program, briefly discuss past and currently sponsored spacecraft charging activities and possible future endeavors.

    1990-01-01

    The results of research and development efforts are described for Task one, Phase two of a general project entitled The Development of a Program Analysis Environment for Ada. The scope of this task includes the design and development of a prototype system for testing Ada software modules at the unit level. The system is called Query Utility Environment for Software Testing of Ada (QUEST/Ada). The prototype for condition coverage provides a platform that implements expert system interaction with program testing. The expert system can modify data in the instrument source code in order to achieve coverage goals. Given this initial prototype, it is possible to evaluate the rule base in order to develop improved rules for test case generation. The goals of Phase two are the following: (1) to continue to develop and improve the current user interface to support the other goals of this research effort (i.e., those related to improved testing efficiency and increased code reliable); (2) to develop and empirically evaluate a succession of alternative rule bases for the test case generator such that the expert system achieves coverage in a more efficient manner; and (3) to extend the concepts of the current test environment to address the issues of Ada concurrency.

    Although diet affects growth and behaviour, the adaptive mechanisms that coordinate these processes in non-optimal food sources are unclear. Here we show that the C. elegans tmc-1 channel, which is homologous to the mammalian tmc deafness genes, attenuates development and inhibits sexual behaviour in non-optimal food, the synthetic CeMM medium. In CeMM medium, signalling from the pharyngeal MC neurons and body wall muscles slows larval development. However, in the non-standard diet, mutation in tmc-1 accelerates development, by impairing the excitability of these cells. The tmc-1 larva can immediately generate ATP when fed CeMM, and their fast development requires insulin signalling. Our findings suggest that the tmc-1 channel indirectly affects metabolism in wild-type animals. In addition to regulating the development, we show that mutating tmc-1 can relax diet-induced inhibition of male sexual behaviour, thus indicating that a single regulator can be genetically modified to promote growth rate and reproductive success in new environments.

    Temple, Meredith D.; Kosik, Kenneth S.; Steward, Oswald

    2002-01-01

    This study evaluated the cognitive mapping abilities of rats that spent part of their early development in a microgravity environment. Litters of male and female Sprague-Dawley rat pups were launched into space aboard the National Aeronautics and Space Administration space shuttle Columbia on postnatal day 8 or 14 and remained in space for 16 days. These animals were designated as FLT groups. Two age-matched control groups remained on Earth: those in standard vivarium housing (VIV) and those in housing identical to that aboard the shuttle (AGC). On return to Earth, animals were tested in three different tasks that measure spatial learning ability, the Morris water maze (MWM), and a modified version of the radial arm maze (RAM). Animals were also tested in an open field apparatus to measure general activity and exploratory activity. Performance and search strategies were evaluated in each of these tasks using an automated tracking system. Despite the dramatic differences in early experience, there were remarkably few differences between the FLT groups and their Earth-bound controls in these tasks. FLT animals learned the MWM and RAM as quickly as did controls. Evaluation of search patterns suggested subtle differences in patterns of exploration and in the strategies used to solve the tasks during the first few days of testing, but these differences normalized rapidly. Together, these data suggest that development in an environment without gravity has minimal long-term impact on spatial learning and memory abilities. Any differences due to development in microgravity are quickly reversed after return to earth normal gravity.

  11. Gene-Environment Interactions in the Development of Complex Disease Phenotypes

    Directory of Open Access Journals (Sweden)

    Kenneth Olden

    2008-03-01

    Full Text Available The lack of knowledge about the earliest events in disease development is due to the multi-factorial nature of disease risk. This information gap is the consequence of the lack of appreciation for the fact that most diseases arise from the complex interactions between genes and the environment as a function of the age or stage of development of the individual. Whether an environmental exposure causes illness or not is dependent on the efficiency of the so-called “environmental response machinery” (i.e., the complex of metabolic pathways that can modulate response to environmental perturbations that one has inherited. Thus, elucidating the causes of most chronic diseases will require an understanding of both the genetic and environmental contribution to their etiology. Unfortunately, the exploration of the relationship between genes and the environment has been hampered in the past by the limited knowledge of the human genome, and by the inclination of scientists to study disease development using experimental models that consider exposure to a single environmental agent. Rarely in the past were interactions between multiple genes or between genes and environmental agents considered in studies of human disease etiology. The most critical issue is how to relate exposure-disease association studies to pathways and mechanisms. To understand how genes and environmental factors interact to perturb biological pathways to cause injury or disease, scientists will need tools with the capacity to monitor the global expression of thousands of genes, proteins and metabolites simultaneously. The generation of such data in multiple species can be used to identify conserved and functionally significant genes and pathways involved in geneenvironment interactions. Ultimately, it is this knowledge that will be used to guide agencies such as the U.S. Department of Health and Human Services in decisions regarding biomedical research funding

    2012-12-31

    The University of Wisconsin Department of Engineering Professional Development (EPD) has completed the sponsored project entitled, Development of a Total Energy, Environment and Asset Management (TE2AM) Curriculum. The project involved the development of a structured professional development program to improve the knowledge, skills, capabilities, and competencies of engineers and operators of commercial buildings. TE2AM advances a radically different approach to commercial building design, operation, maintenance, and end of life disposition. By employing asset management principles to the lifecycle of a commercial building, owners and occupants will realize improved building performance, reduced energy consumption and positive environmental impacts. Through our commercialization plan, we intend to offer TE2AM courses and certificates to the professional community and continuously improve TE2AM course materials. The TE2AM project supports the DOE Strategic Theme 1 Energy Security; and will further advance the DOE Strategic Goal 1.4 Energy Productivity. Through participation in the TE2AM curriculum, engineers and operators of commercial buildings will be eligible for a professional certificate; denoting the completion of a prescribed series of learning activities. The project involved a comprehensive, rigorous approach to curriculum development, and accomplished the following goals: 1. Identify, analyze and prioritize key learning needs of engineers, architects and technical professionals as operators of commercial buildings. 2. Design and develop TE2AM curricula and instructional strategies to meet learning needs of the target learning community. 3. Establish partnerships with the sponsor and key stakeholders to enhance the development and delivery of learning programs. 4.

    The Looking for Life in Extreme Environments workshop held at Indiana University Bloomington in July of 2009 was the first in a series of workshops for high-school teachers that are currently in development. The workshops' modules are based on the research of faculty members in the Departments of Geological Sciences, Biology, and Astronomy, the School of Education, and the School of Public and Environmental Affairs at Indiana University Bloomington; the modules use lessons from Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities, curricular materials that were produced and edited by Lisa Pratt and Ruth Droppo and published by NASA in 2008. Exploring Deep-Subsurface Life is a workbook, a DVD (with closed-captioning), and a CD with the lessons in digital text format for adaptation to classroom needs and printing. Each lesson includes the National Education Standards that apply to the materials. The workbook's lessons are written with three considerations: Life Domains, Cellular Metabolism, and Extreme Environments and Microbes. Students are challenged to build, draw, measure, discuss, and participate in laboratory processes and experiments that help them understand and describe microbes and their environments. In the Capstone, the students write a grant proposal based on the three lessons' analogues. The DVD is collection of videotaped interviews with scientists in laboratories at Michigan State, Princeton, and Indiana University, who are working on water and gas samples they collected from deep gold mines in South Africa and the Canadian Arctic. The interview materials and some animated graphics are compiled into four video pieces that support and compliment the accompanying workbook lessons and activities, and offer students insight into the excitement of scientific discovery.

    Ice covered regions comprise >10% of Earth's continental area; and include regions with poorly understood ice dynamics, ice shelf stability, hydrology, tectonic histories and basic geologic structure both deep and shallow. Scientific investigations of these regions are challenged by extreme weather, limited and expensive logistics, and the physical conditions of the ice environment. We report on the next development of a new NSF MRI-supported community seismic capability for studying ice-covered regions- the Geophysical Earth Observatory for Ice Covered Environments (GEOICE). This project is fundamentally motivated by the need to densify and optimize the collection of high-quality data relevant to key solid Earth and cryosphere science questions. The instrument capability will include a hybrid seismograph pool of broadband and intermediate elements, for observation of both long-period (e.g., long-period surface waves and slow sources) and intermediate-to-short-period (e.g., teleseismic body waves local seismicity, impulsive or extended glaciogenic signals). The GEOICE instrument, and its power and other ancillary systems, will be specifically designed to both withstand conditions associated with icy environments, including cold/wet conditions and high-latitude solar limitations, and to require minimal installation time and logistical load (i.e., size and weight), while maximizing ease-of-use in the field, in data handling, and in telemetry compatibility. Key features will include a design that integrates the seismometer and data logger into a single environmentally and mechanically robust housing, very low power requirements (inventory of stations and will be maintained and supported at the IRIS PASSCAL Instrument Center to ensure full and flexible peer-reviewed community use.

    Full Text Available Of concern in this paper is an investigation of the entrance length behind singularities in cardiovascular hemodynamics under magnetic environment. In order to get better interpretation of scan MRI images, the characteristics of blood flow and electromagnetic field within the circulatory system have to be furthermore investigated. A 3D numerical model has been developed as an example of blood flowing through a straight circular tube. The governing coupled nonlinear differential equations of magnetohydrodynamic (MHD fluid flow are reduced to a nondimensional form, which are then characterized by four dimensionless parameters. With an aim to validate our numerical approach, the computational results are compared with those of the analytical solution available in the developed region far from the singularity. The hydraulic impedance by unit length within the developed flow region increases with the magnetic field. The time average entrance length with a greater precision on the unsteady case decreases with increasing magnetic field strength. The overall voltage characteristics do not depend on the developed flow field within the entry region.

  16. A new practice-driven approach to develop software in a cyber-physical system environment

    Cyber-physical system (CPS) is an emerging area, which cannot work efficiently without proper software handling of the data and business logic. Software and middleware is the soul of the CPS. The software development of CPS is a critical issue because of its complicity in a large scale realistic system. Furthermore, object-oriented approach (OOA) is often used to develop CPS software, which needs some improvements according to the characteristics of CPS. To develop software in a CPS environment, a new systematic approach is proposed in this paper. It comes from practice, and has been evolved from software companies. It consists of (A) Requirement analysis in event-oriented way, (B) architecture design in data-oriented way, (C) detailed design and coding in object-oriented way and (D) testing in event-oriented way. It is a new approach based on OOA; the difference when compared with OOA is that the proposed approach has different emphases and measures in every stage. It is more accord with the characteristics of event-driven CPS. In CPS software development, one should focus on the events more than the functions or objects. A case study of a smart home system is designed to reveal the effectiveness of the approach. It shows that the approach is also easy to be operated in the practice owing to some simplifications. The running result illustrates the validity of this approach.

    The objectives of this research were to further characterize exotic by adapted corn inbreds by studying the impact of environment on their starch thermal properties, and investigating the development of starch thermal properties during kernel maturation by using differential scanning calorimetry (DSC). A method to expedite identification of unusual starch thermal traits was investigated by examining five corn kernels at a time, instead of one kernel, which the previous screening methods used. Corn lines with known thermal functions were blended with background starch (control) in ratios of unique starch to control starch, and analyzed by using DSC. Control starch was representative of typical corn starch. The values for each ratio within a mutant type were unique (α < 0.01) for most DSC measurements. These results supported the five-kernel method for rapidly screening large amounts of corn germplasm to identify unusual starch traits. The effects of 5 growing locations on starch thermal properties from exotic by adapted corn and Corn Belt lines were studied using DSC. The warmest location, Missouri, generally produced starch with greater gelatinization onset temperature (ToG), narrower range of gelatinization (RG), and greater enthalpy of gelatinization (ΔHG). The coolest location, Illinois, generally resulted in starch with lower ToG, wider RG, and lower ΔHG. Starch from the Ames 1 farm had thermal properties similar to those of Illinois, whereas starch from the Ames 2 farm had thermal properties similar to those of Missouri. The temperature at Ames 2 may have been warmer since it was located near a river; however, soil type and quality also were different. Final corn starch structure and function change during development and maturity. Thus, the changes in starch thermal properties during 5 stages of endosperm development from exotic by adapted corn and Corn Belt lines at two locations were

    The development of the preimplantation embryo seems morphologically very simple, and embryologists previously assumed that an embryo that developed to the blastocyst stage was fully capable of normal development after transfer to the uterus of a recipient female. This complacency was disturbed by reports that exposure of early embryos to mutagens such as methylnitrosourea led to fetal abnormalities, decreased birth rates, and decreased life-span. Even more disturbing are recent reports that culture of early embryos in supposedly benign conditions can adversely affect their subsequent development. Techniques have been developed for the production of cattle and sheep embryos by in-vitro fertilization and by cloning. Such embryos must be cultured for several days before they can be transferred, and, in some cases, this has been related to abortion, very high birthweight, physical abnormalities and peri-natal mortality of the calves and lambs. This syndrome may result from an unbalanced development of the trophoblast relative to the inner-cell mass, possibly related to the presence of serum, glucose, or ammonium in the culture medium. An analogous phenomenon has been observed in human in-vitro fertilization where babies from single pregnancies have below-normal birth-weight. There is also evidence to suggest that the in-vitro environment of the gametes before fertilization can affect subsequent embryonal and fetal development. Exposure of mouse oocytes to vitrification solutions has been shown to lead to fetal malformations, and treatment of bull sperm with glutathione improves early embryo development. The common thread in these diverse observations is that development can be affected by events that occur long before any defect is apparent. Consequently, the production of a morphologically normal embryo is no guarantee that fetal development and post-natal life will be normal. This is of immediate concern in human reproductive medicine due to the increasing use of

    The Formation Flying Testbed (FFTB) at the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) provides a hardware-in-the-loop test environment for formation navigation and control. The facility is evolving as a modular, hybrid, dynamic simulation facility for end-to-end guidance, navigation and. control (GN&C) design and analysis of formation flying spacecraft. The core capabilities of the FFTB, as a platform for testing critical hardware and software algorithms in-the-loop, have expanded to include S-band Radio Frequency (RF) modems for inter-spacecraft communication and ranging. To enable realistic simulations that require RF ranging sensors for relative navigation, a mechanism is needed to buffer the RF signals exchanged between spacecraft that accurately emulates the dynamic environment through which the RF signals travel, including the effects of medium, moving platforms, and radiated power. The Path Emulator for RF Signals (PERFS), currently under development at NASA GSFC, provides this capability. The function and performance of a prototype device are presented.

    Full Text Available This study aims to introduce Virtual Reality (VR techniques as a tool to develop an interactive environment for cultural heritage sites in Palestine; these sites have their own specific problems and challenges, which have significantly affected most of the existing sites and cause their continuous deterioration. The virtual replicas of these sites and landscapes can act as a medium for their preservation, documentation, interpretation and intervention, assisting in education, tourism and an increase in public awareness regarding their significant value. For this purpose, Hisham Palace in Jericho was chosen as a case study. The historical layers of Hisham Palace were studied and visualized using advanced 3D visualization techniques by applying a five-step approach to analyze and model different elements of the palace to assemble them at a later stage. This approach was implemented due to the critical condition of the physical remains and the insufficient literature on the history of the palace. As a result, a initial 3D virtual reality model was obtained, presented and discussed in a 3D immersive  environment at the Virtual Reality Lab (VR Lab at Birzeit University.

    2014-01-01

    The purpose of NASA Extreme Environment Mission Operations (NEEMO) mission 16 in 2012 was to evaluate and compare the performance of a defined series of representative near-Earth asteroid (NEA) extravehicular activity (EVA) tasks under different conditions and combinations of work systems, constraints, and assumptions considered for future human NEA exploration missions. NEEMO 16 followed NASA's 2011 Desert Research and Technology Studies (D-RATS), the primary focus of which was understanding the implications of communication latency, crew size, and work system combinations with respect to scientific data quality, data management, crew workload, and crew/mission control interactions. The 1-g environment precluded meaningful evaluation of NEA EVA translation, worksite stabilization, sampling, or instrument deployment techniques. Thus, NEEMO missions were designed to provide an opportunity to perform a preliminary evaluation of these important factors for each of the conditions being considered. NEEMO 15 also took place in 2011 and provided a first look at many of the factors, but the mission was cut short due to a hurricane threat before all objectives were completed. ARES Directorate (KX) personnel consulted with JSC engineers to ensure that high-fidelity planetary science protocols were incorporated into NEEMO mission architectures. ARES has been collaborating with NEEMO mission planners since NEEMO 9 in 2006, successively building upon previous developments to refine science operations concepts within engineering constraints; it is expected to continue the collaboration as NASA's human exploration mission plans evolve.

    In this study, we report the development of a microenvironment probe station capable of detecting the effect of small changes to the local environment around a carbon nanotube conduction channel. The microenvironment probe station is highly versatile and is used to characterize alterations in carbon nanotube field effect transistor electrical behavior in response to changes in temperature, gas species, infrared and ultraviolet light. All devices were electrically characterized in atmospheric, ultrahigh vacuum and oxygen-rich environments. The results suggest that devices could be changed from n-type at 1 x 10(-8) torr through an intermediate ambipolar state at 1 x 10(-4) torr to p-type at atmosphere solely by increasing the oxygen concentration. The average resistance of these carbon nanotube field effect transistors after annealing was observed to decrease by approximately 54% from their initial value under ultrahigh vacuum to their final value in the presence of pure oxygen while corresponding threshold voltages shifts were also observed. Illumination with infrared light resulted in a approximately 10% increase in drain current with an estimated response time <1 fs due to photon-induced electron-hole pair generation. Illumination with ultraviolet light resulted in approximately 5-15% reduction in drain current due to photon-induced desorption of oxygen adsorbate.

    Americans are increasingly eating out, but nutrition environments in restaurants are poorly understood. An observational measure was developed to assess factors believed to contribute to food choices in restaurants, including availability of more healthy foods, facilitators and barriers to healthful eating, pricing, and signage/promotion of healthy and unhealthy foods. Inter-rater and test-retest reliability were assessed in 217 sit-down and fast-food restaurants in four neighborhoods in 2004 and 2005. Inter-rater reliability was generally high, with most kappa values greater than 0.80 (range 0.27-0.97) and all percent-agreement values greater than 75% (77.6-99.5). Test-retest reliability was high, with most kappa values greater than 0.80 (0.46-1.0) and all percent-agreement values greater than 80% (80.4-100). There were several differences (pNEMS-R) has evidence of reliability, and can discriminate restaurant types. The NEMS-R can be used in research and practice to characterize restaurant environments.

  5. Behavioral susceptibility to obesity: Gene-environment interplay in the development of weight.

    There is considerable evidence for both environmental and genetic causes of obesity. Increased availability of cheap, palatable food plays a role, but despite the ubiquity of the 'obesogenic' environment there is still substantial variation in weight - in fact, weight variability has gone up over recent decades. Twin and adoption studies show that adiposity is highly heritable (50-90%), and genome-wide association studies have started to identify single nucleotide polymorphisms (SNPs) associated with weight. We have proposed that genetic susceptibility to obesity is partly attributable to appetitive phenotypes, called the behavioral susceptibility theory (BST). BST proposes that individuals who inherit a more avid appetite or lower sensitivity to satiety are more likely to overeat in response to the food environment. Our laboratory has provided considerable evidence for BST using a variety of research approaches. We have used prospective epidemiological studies to demonstrate that appetite plays a causal role in the development of weight, twin designs to show that appetitive phenotypes are highly heritable and have genetic overlap with adiposity, and genomic analyses to show that obesity-related SNPs are associated with appetite and that appetite mediates some of the SNP-adiposity association. BST has helped to resolve the seeming paradox of both genetic determination and environmental determination of weight, and points to appetite as a useful target for pharmacological and behavioral interventions in the prevention and management of obesity.

    Full Text Available The main objectives of this paper is to emphasize the important role played by Structural andCohesion Funds for business environment development, especially in times of economic downturn when thefinancial resources are difficult to access. Prior work regarding the promotion of good administration ofstructural funds in new member states was carried out by NGOs. The main methods employed for capturingthe research evidence consists in comparative analysis of the related work, and also in studying the capacityof absorption of European funds in the case Romania, especially from the SMEs perspective. The mainresults show that European Funds absorption is delayed and negatively influenced by a series of factors. Theimportance of European financial assistance through Structural and Cohesion Funds is undeniable, especiallyin times of financial crisis, so implications of this study are important to entrepreneurs, especially for SMEsbut also to policy-makers, because they can design the procedures of accessing this funds in order to easy thisprocess. The value of this paper ensues from the original approach of contradictory role played by Europeanfunds for Romanian business environment, because it represents the mirage of overcoming economic crisis.

    Full Text Available The use of assertions for monitoring the designer’s intention in hardware description language (HDL model is gaining popularity as it helps the designer to observe internal errors at the output ports of the device under verification. During verification assertions are synthesised and the generated data are represented in a tabular forms. The amount of data generated can be enormous depending on the size of the code and the number of modules that constitute the code. Furthermore, to manually inspect these data and diagnose the module with functional violation is a time consuming process which negatively affects the overall product development time. To locate the module with functional violation within acceptable diagnostic time, the data processing and analysis procedure must be accelerated. In this paper a multi-array processor (hardware accelerator was designed and implemented in Virtex6 field programmable gate array (FPGA and it can be integrated into verification environment. The design was captured in very high speed integrated circuit HDL (VHDL. The design was synthesised with Xilinx design suite ISE 13.1 and simulated with Xilinx ISIM. The multi-array processor (MAP executes three logical operations (AND, OR, XOR and a one’s compaction operation on array of data in parallel. An improvement in processing and analysis time was recorded as compared to the manual procedure after the multi-array processor was integrated into the verification environment. It was also found that the multi-array processor which was developed as an Intellectual Property (IP core can also be used in applications where output responses and golden model that are represented in the form of matrices can be compared for searching, recognition and decision-making.

    Although there are a number of studies examining the effect of migration on obesity, these studies tend to focus on the role of acculturation in this relationship. However, there are indications that the change in environment may also be an important factor. Indeed, there is a considerable lack of psychometric tools designed to assess the association between environment and migrant health behaviour. The current study aimed to assess the literature on the link between environment and health for migrants, and on the basis of this information, design and develop the Migrant Obesogenic Perception of the Environment questionnaire (MOPE-Q). The MOPE-Q is the first comprehensive measure of the impact of environmental factors on migrant health behaviour related to physical activity, food habits and body image concern, as well as weight change. Using a systematic approach, an initial pool of items for the questionnaire was developed and refined on the basis of rigorous content and face validity assessments and factor analysis. Further, reliability tests and test re-test studies were undertaken. Differences between Iranian and Australian environmental factors as they relate to obesogenic behaviour were explored using the developed measure. A total of 36 items were developed for the MOPE-Q. Principal factor analysis identified three similar factor structures of environmental factors related to obesity (categorized in terms of facilitators, barriers and pressures) for each country. The final questionnaire consisted of four distinct subscales pertaining specifically to the Australian environment and five subscales pertaining to the Iranian environment, accounting for 59% and 63%, respectively, of the total variance in obesity rates. Data suggests that the MOPE-Q is a reliable and valid self-report measure for assessing the relationship between environmental factors linked to obesity and obesogenic behaviour for this particular migrant group. The variations in environmental

    Full Text Available Based on regional coordination theory and system theory, the authors constructed an evaluation index system for the coordinated development of a regional environment-tourism-economy system with a pressure-state-response (PSR model. With a coordinated development model, it further empirically analyzed the coordinated development state of an environment-tourism-economy system in western Hunan from 2001 to 2012. The results showed that, although this environment-tourism-economy system failed to achieve a high benefit index, inter-subsystem coupling extent, and coordinated development index, the three indices presented an increasing overall trend. This outcome suggested that the sub-systems in this system were developing towards their optimal proportions: the development of these sub-systems (environmental, tourism, and economic was unbalanced in western Hunan. The environment therein sees only slow development although provided with a favorable ecological foundation. Economic development, which has long been lagging, acted as the main factor restricting the coordinated development of a regional environment-tourism-economy system. To promote its coordinated development in western Hunan, the following recommendations were proposed: strengthen the prediction and warnings on the evolution of the whole system; optimize the industry’s structure; reinforce environmental management.

    The present paper outlines the present situation of environment of developing countries, factors causing environmental devastation, and the influence in the international linkage as described in 1992 White Paper on Environment. The present environmental devastation is originated from national poverty. In general, as the results of imposing excessive pressure on the natural environment accompanying the increase of population or causing urban pollution due to the movement or densification of population, poverty brings about the reduction and devastation of forest, deterioration of soil, desertification, contamination of air and rivers, causing miserable situation. Prawn culture as primary export industry damages mangrove woods, and causes water pollution. Industrial development is rapidly spreading pollution of water and air. As for international relations, the net transfer amount of money in the flow of funds between advanced countries and developing countries is in the direction from the latter to the former due to payment of debts. In enforcing direct investment or overseas development aid projects, advanced countries must be aware of their responsibility, make efforts in grasping the situations of aided countries and perform sufficient environmental assessment. 5 refs., 8 figs., 11 tabs.

    The Environment Power System Analysis Tool (EPSAT) is being developed to provide engineers with the ability to assess the effects of a broad range of environmental interactions on space power systems. A unique user-interface-data-dictionary code architecture oversees a collection of existing and future environmental modeling codes (e.g., neutral density) and physical interaction models (e.g., sheath ionization). The user-interface presents the engineer with tables, graphs, and plots which, under supervision of the data dictionary, are automatically updated in response to parameter change. EPSAT thus provides the engineer with a comprehensive and responsive environmental assessment tool and the scientist with a framework into which new environmental or physical models can be easily incorporated.

    The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information between vehicles and the roadside infrastructures for making an intelligent use of them. There are several possible applications for this technology like: emergency warning system for vehicles, cooperative adaptive cruise control or collision avoidance, among others. The objective of this work is to develop a VANET prototype system for urban environments using IEEE 802.15.4 compliant devices. Simulation-based values of the estimated signal strength and radio link quality values are obtained and compared with measurements in outdoor conditions to validate an implemented VANET system. The results confirm the possibility of implementing low cost vehicular communication networks operating at moderate vehicular speeds.

    2003-01-01

    One of the most challenging issues faced in HEP in recent years is the question of how to capitalise on software development and maintenance experience in a continuous manner. To capitalise means in our context to evaluate and apply new process technologies as they arise, and to further evolve technologies already widely in use. It also implies the definition and adoption of standards. The CMS off- line software improvement effort aims at continual software quality improvement, and continual improvement in the efficiency of the working environment with the goal to facilitate doing great new physics. To achieve this, we followed a process improvement program based on ISO-15504, and Rational Unified Process. This experiment in software process improvement in HEP has been progressing now for a period of 3 years. Taking previous experience from ATLAS and SPIDER into account, we used a soft approach of continuous change within the limits of current culture to create of de facto software process standards within th...

    One of the frontiers in intelligent machine research is the understanding of how constructive cooperation among multiple autonomous agents can be effected. The effort at the Center for Engineering Systems Advanced Research (CESAR)at the Oak Ridge National Laboratory (ORNL) focuses on two problem areas: (1) cooperation by multiple mobile robots in dynamic, incompletely known environments; and (2) cooperating robotic manipulators. Particular emphasis is placed on experimental evaluation of research and developments using the CESAR robot system testbeds, including three mobile robots, and a seven-axis, kinematically redundant mobile manipulator. This paper summarizes initial results of research addressing the decoupling of position and force control for two manipulators holding a common object, and the path planning for multiple robots in a common workspace. 15 refs., 3 figs.

    Reduction in safety margin can be expected as passive structures and components undergo degradation with time. Limitations in the traditional probabilistic risk assessment (PRA) methodology constrain its value as an effective tool to address the impact of aging effects on risk and for quantifying the impact of aging management strategies in maintaining safety margins. A methodology has been developed to address multiple aging mechanisms involving large numbers of components (with possibly statistically dependent failures) within the PRA framework in a computationally feasible manner when the sequencing of events is conditioned on the physical conditions predicted in a simulation environment, such as the New Generation System Code (NGSC) concept. Both epistemic and aleatory uncertainties can be accounted for within the same phenomenological framework and maintenance can be accounted for in a coherent fashion. The framework accommodates the prospective impacts of various intervention strategies such as testing, maintenance, and refurbishment. The methodology is illustrated with several examples.

    Fibromyalgia (FM) is a disorder characterized by chronic physical pain. The perception of this pain has psychological effects on mood, anxiety, and the degree of perceived control. In turn, these factors may increase the experience of pain. This study aims to develop a new virtual environment for the treatment of FM in order to enhance the therapeutic effects of traditional interventions. The first phase included a sample of 19 patients in order to identify common characteristics of the representation of pain and absence of pain, through drawing. The results showed that patients used different colors and different physical states to depict pain (red, motionless) and the absence of pain (blue, in motion). These features were then included in a 3D representation of the human body. ANOVA analysis showed that the degree of anxiety and depression influenced the perceived characteristic of movement.

    The design and analysis of plasma spectroscopy experiments can be significantly complicated by relatively routine computational tasks arising from the massive amount of data encountered in the experimental design and analysis stages of the work. Difficulties in obtaining, computing, manipulating and visualizing the information represent not simply an issue of convenience -- they have a very real limiting effect on the final quality of the data and on the potential for arriving at meaningful conclusions regarding an experiment. We describe ongoing work in developing a portable UNIX environment shell with the goal of simplifying and enabling these activities for the plasma-modeling community. Applications to the construction of atomic kinetics models and to the analysis of x-ray transmission spectroscopy will be shown.

    Land carrying capacity is an important index of evaluation on land resources. And the land carrying capacity is also very important for guiding regional plans and promoting sustainable development of regional economy. So it is significant to clarify the land carrying capacity in the sequence of events which helps the decision makers understand and grasp the knowledge of land carrying capacity more clearly and make the right judgment and decision. Based on the theory of population, resources, environment and economy, the method of reviewing literatures is used in this paper to summarize the theory of the land carrying capacity and the researching methods of the land carrying capacity, as well as the problems existing in the study of land carrying capacity.

    Full Text Available The primary objective of this research was the development of a problem-based learning model using a virtual learning environment (VLE for undergraduate students in the Photography for Communication Arts course. The model supports and enhances students' learning, achievements and problem-solving skills. An efficiency test for the model revealed an above average set of criteria at 80/83.93, which conformed to the research hypothesis. The principles of instructional systems design (ISD and systems approach were integrated into the design and assessment phases of model development, which resulted in more effective management of relevant instructional courses and materials. Based on its efficiency and potential application to real-life situations, the model has been deemed suitable by experts. The selected student group in the problem-based learning model via VLE achieved higher test scores compared to a group of students in a normal classroom with a statistical significance of .05. Because students learn using models that promote self-awareness and make it possible to choose their own topic of study employing resources provided by VLE, an assessment of their work quality found that they gained more knowledge of information technology as well as access to up-to-date information. Students are able to choose the most comfortable time to study. The model encourages students to learn through participation, practice problem-solving skills on an individual basis, and exchange ideas with other members of a group. The virtual environment involves many forms of media and materials that stimulate students' interest in learning and results in higher satisfaction. The gap in the communication channel between students and teachers is reduced due to easier and more informal communication.

    A return to the Moon to extend human presence, pursue scientific activities, use the Moon to prepare for future human missions to Mars, and expand Earth?s economic sphere, will require investment in developing new technologies and capabilities to achieve affordable and sustainable human exploration. From the operational experience gained and lessons learned during the Apollo missions, conducting long-term operations in the lunar environment will be a particular challenge, given the difficulties presented by the unique physical properties and other characteristics of lunar regolith, including dust. The Apollo missions and other lunar explorations have identified significant lunar dust-related problems that will challenge future mission success. Comprised of regolith particles ranging in size from tens of nanometers to microns, lunar dust is a manifestation of the complex interaction of the lunar soil with multiple mechanical, electrical, and gravitational effects. The environmental and anthropogenic factors effecting the perturbation, transport, and deposition of lunar dust must be studied in order to mitigate it?s potentially harmful effects on exploration systems and human explorers. The Dust Management Project (DMP) is tasked with the evaluation of lunar dust effects, assessment of the resulting risks, and development of mitigation and management strategies and technologies related to Exploration Systems architectures. To this end, the DMP supports the overall goal of the Exploration Technology Development Program (ETDP) of addressing the relevant high priority technology needs of multiple elements within the Constellation Program (CxP) and sister ETDP projects. Project scope, plans, and accomplishments will be presented.

  7. Adaptation of a Control Center Development Environment for Industrial Process Control

    1994-01-01

    In the control center, raw telemetry data is received for storage, display, and analysis. This raw data must be combined and manipulated in various ways by mathematical computations to facilitate analysis, provide diversified fault detection mechanisms, and enhance display readability. A development tool called the Graphical Computation Builder (GCB) has been implemented which provides flight controllers with the capability to implement computations for use in the control center. The GCB provides a language that contains both general programming constructs and language elements specifically tailored for the control center environment. The GCB concept allows staff who are not skilled in computer programming to author and maintain computer programs. The GCB user is isolated from the details of external subsystem interfaces and has access to high-level functions such as matrix operators, trigonometric functions, and unit conversion macros. The GCB provides a high level of feedback during computation development that improves upon the often cryptic errors produced by computer language compilers. An equivalent need can be identified in the industrial data acquisition and process control domain: that of an integrated graphical development tool tailored to the application to hide the operating system, computer language, and data acquisition interface details. The GCB features a modular design which makes it suitable for technology transfer without significant rework. Control center-specific language elements can be replaced by elements specific to industrial process control.

    Full Text Available Postinfectious IBS is defined in the industrialized world as IBS onset following a sentinel gastrointestinal infection. In developing nations, where repeated bacterial and parasitic gastrointestinal infections are common, the IBS pathophysiology may be altered. Our aim was to investigate the relationship between intestinal parasite infection and IBS in the “nonsterile” developing world environment. IBS subjects were identified from a population-based sample of 1624 participants using the Rome II Modular Questionnaire. Stool samples from cases and randomly selected controls were examined for ova and parasites. Logistic regression models explored the relationship between IBS and parasite infection. The overall IBS prevalence among participants was 13.2% (9.3% males, 15.9% females. There was no difference in parasite carriage between IBS cases and controls, 16.6% versus 15.4% (P=0.78, nor among IBS subtypes. The pathophysiology of post-infectious IBS may be altered in the developing world as compared to industrialized nations and warrants investigation.

    The STA basic system has been enhanced to accelerate support for parallel programming on heterogeneous parallel computers, through a series of R and D on the technology of parallel processing. The enhancement has been made through extending the function of the PPDF, Parallel Program Development Environment in the STA basic system. The extended PPDE has the function to make: 1) the automatic creation of a 'makefile' and a shell script file for its execution, 2) the multi-tools execution which makes the tools on heterogeneous computers to execute with one operation a task on a computer, and 3) the mirror composition to reflect editing results of a file on a computer into all related files on other computers. These additional functions will enhance the work efficiency for program development on some computers. More functions have been added to the PPDE to provide help for parallel program development. New functions were also designed to complement a HPF translator and a paralleilizing support tool when working together so that a sequential program is efficiently converted to a parallel program. This report describes the use of extended PPDE. (author)

    The home environment has a significant influence on children's physical activity, sedentary behavior, dietary intake, and risk for obesity and chronic disease. Our understanding of the most influential factors and how they interact and impact child behavior is limited by current measurement tools, specifically the lack of a comprehensive instrument. HomeSTEAD (the Home Self-administered Tool for Environmental assessment of Activity and Diet) was designed to address this gap. This new tool contains four sections: home physical activity and media equipment inventory, family physical activity and screen time practices, home food inventory, and family food practices. This paper will describe HomeSTEAD's development and present reliability and validity evidence for the first section. The ANGELO framework guided instrument development, and systematic literature reviews helped identify existing items or scales for possible inclusion. Refinement of items was based on expert review and cognitive interviews. Parents of children ages 3-12 years (n = 125) completed the HomeSTEAD survey on three separate occasions over 12-18 days (Time 1, 2, and 3). The Time 1 survey also collected demographic information and parent report of child behaviors. Between Time 1 and 2, staff conducted an in-home observation and measured parent and child BMI. Kappa and intra-class correlations were used to examine reliability (test-retest) and validity (criterion and construct). Reliability and validity was strong for most items (97% having ICC > 0.60 and 72% having r > 0.50, respectively). Items with lower reliability generally had low variation between people. Lower validity estimates (r environment factors and BMI, outside time, and screen time were observed (e.g., amount of child portable play equipment in good condition and easy to access was significantly associated with child BMI: r = -0.23), providing evidence of construct validity. The HomeSTEAD instrument represents a clear advancement in

    This document is the final scientific report of the project DE-SC000120 (A scalable Development Environment for Peta-Scale Computing). The objective of this project is the extension of the Parallel Tools Platform (PTP) for applying it to peta-scale systems. PTP is an integrated development environment for parallel applications. It comprises code analysis, performance tuning, parallel debugging and system monitoring. The contribution of the Juelich Supercomputing Centre (JSC) aims to provide a scalable solution for system monitoring of supercomputers. This includes the development of a new communication protocol for exchanging status data between the target remote system and the client running PTP. The communication has to work for high latency. PTP needs to be implemented robustly and should hide the complexity of the supercomputer's architecture in order to provide a transparent access to various remote systems via a uniform user interface. This simplifies the porting of applications to different systems, because PTP functions as abstraction layer between parallel application developer and compute resources. The common requirement for all PTP components is that they have to interact with the remote supercomputer. E.g. applications are built remotely and performance tools are attached to job submissions and their output data resides on the remote system. Status data has to be collected by evaluating outputs of the remote job scheduler and the parallel debugger needs to control an application executed on the supercomputer. The challenge is to provide this functionality for peta-scale systems in real-time. The client server architecture of the established monitoring application LLview, developed by the JSC, can be applied to PTP's system monitoring. LLview provides a well-arranged overview of the supercomputer's current status. A set of statistics, a list of running and queued jobs as well as a node display mapping running jobs to their compute

    Full Text Available The building project development approval process is increasingly complex and fraught with conflict due to the rise of the sustainable urban development movement and inclusive decision making. Coupled with this, government decision-making decentralization has resulted in a fragmented and over-regulated compliance system. Problems arising from the process include wasted resources, excessive time delays, increased holding and litigation costs, inadequate planning coordination, high levels of advocacy costs and a divisive politicized approval process. In Australia, despite attempts by government and industry associations, numerous problems are still unresolved. Design managers increasingly assume a liaison role during the approval phase. There is a long tradition of planning theory literature which provides context for understanding the knowledge-power-participation relationship for this paper. This study investigated the policy, process and practice conflicts during the approval stage in achieving sustainable urban developments. Three regional local government areas within one state jurisdiction and observations from detailed structured focus group interviews involving 23 stakeholders, proposers and assessors were analysed to explore this conflictual environment. As a result of regulatory fragmentation and excessive consultation, various persuasion tactics have been developed by all stakeholders of which `reciprocity' and `authority' were identified as the most common. Two challenges for design managers were thus identified: first, the emergence of the role of a by default central informal arbitrator across conflicting planning instruments; and, second, as a navigator through a set of persuasion tactics. An inclusive knowledge-based design management framework for sustainable urban development is proposed considering Habermas' communicative planning theory, Foucaltian governance and discursive powers thesis and Cialdini's persuasion theory, as

    Full Text Available Background: Premature failures of wheelchairs in less-resourced environments (LREs may be because of shortcomings in product regulation and quality standards. The standards published by the International Organization for Standardization (ISO specify wheelchair tests for durability, safety and performance, but their applicability to products used in the rugged conditions of LREs is unclear. Because of this, wheelchair-related guidelines published by the World Health Organization recommended developing more rigorous durability tests for wheelchairs.Objectives: This study was performed to identify the additional tests needed for LREs.Methods: First, a literature review of the development of ISO test standards, wheelchair standards testing studies and wheelchair evaluations in LREs was performed. Second, expert advice from members of the Standards Working Group of the International Society of Wheelchair Professionals (ISWP was compiled and reviewed.Results: A total of 35 articles were included in the literature review. Participation from LREs was not observed in the ISO standards development. As per wheelchair testing study evidence, wheelchair models delivered in LREs did not meet the minimum standards requirement. Multiple part failures and repairs were observed with reviewed field evaluation studies. ISWP experts noted that several testing factors responsible for premature failures with wheelchair parts are not included in the standards and accordingly provided advice for additional test development.Conclusion: The study findings indicate the need to develop a wide range of tests, with specific tests for measuring corrosion resistance of the entire wheelchair, rolling resistance of castors and rear wheels, and durability of whole wheelchair and castor assemblies.

    Full Text Available The aim of this study is to develop a community feeling scale in order to analyze the community feeling of learners, enrolled in a distance education program which is designed with blended learning model, in online environments. Providing interaction with information communication technologies come into prominence as a result of increasing importance of these technologies in distance education. Although this situation has positive contributions, it may have negative effects on decrement of the motivation, achievement, satisfaction or learning of student such as social isolation, aprosexia, and feeling of alienation. The role of community feeling is major on drop out rates, which is one of the quality indicators of distance education. Rovai (2001b defined classroom community components, including McMillan and Chavis‟s four components of community dimensions. These components are spirit, trust, influence and learning. Spirit shows the acceptance of the membership in the community and develops the feelings of friendship, commitment and satisfaction between the students. Trust is the second one of the class community components. It will be friendly and constructive if the community can be trusted and be given feedback by individuals. When individuals have been accepted by a growing and developing community, they feel more in safe and start to trust to community. The third component, influence is the feeling of closeness and mutual benefit between the individuals. The last component learning is the feeling that community enhances the acquisition of knowledge and understanding, and also the feeling of active information and meaning conformation which supplies the educational needs of the individuals that it consists of. According to the research results, the community feeling of students has so many positive effects. Strong community feeling have positive outcomes as increasing the flow of information, access to support, collaboration between the

Author’s methods of the organisation of students’ work with the text on electronic data storage devices are used during modelling experiment. Methods of questioning, interrogation are applied; the content-analysis and the correlation analysis of the received data.Results. Stages of the person’s creative self-development composing a dialectic cycle of formation and development of research skills of the pupil in educational process are noted. The interrelation between scientifically-methodical readiness of the teacher for development of research potential of students and features of the organisation of their work with the text is established. Ways of activization of pupils’ creative self-development are offered and shown while working with the electronic text and the Internet resources. The given ways allow to realize the idea of subjectiveness and the subjectivity, pointed within the limits of culturological and anthropological approaches to education; to stimulate the process of formation and personality growth of the student; to provide sensibleness of a student’s choice of own trajectory of education; to open its intellectual and creative abilities.Scientific novelty. The variant of transition of school education from positions of transmission of the educational information, completed knowledge and abilities to formation and subjectness development of students and satisfaction of their requirements for creative self-realisation is shown. For this purpose, according to the author, it is necessary to use manifold opportunities of digital technologies actively introduced recently in student teaching not as

    Liberal arts colleges constitute an important source of and training ground for future scientists. At Lawrence University, we take advantage of our small college environment to prepare physics students for research careers by complementing content acquisition with skill development and project experience distributed throughout the curriculum and with co-curricular elements that are tied to our close-knit supportive physics community. Small classes and frequent contact between physics majors and faculty members offer opportunities for regular and detailed feedback on the development of research relevant skills such as laboratory record-keeping, data analysis, electronic circuit design, computational programming, experimental design and modification, and scientific communication. Part of our approach is to balance collaborative group work on small projects (such as Arduino-based electronics projects and optical design challenges) with independent work (on, for example, advanced laboratory experimental extensions and senior capstone projects). Communal spaces and specialized facilities (experimental and computational) and active on-campus research programs attract eager students to the program, establish a community-based atmosphere, provide unique opportunities for the development of research aptitude, and offer opportunities for genuine contribution to a research program. Recently, we have also been encouraging innovativetendencies in physics majors through intentional efforts to develop personal characteristics, encouraging students to become more tolerant of ambiguity, risk-taking, initiative-seeking, and articulate. Indicators of the success of our approach include the roughly ten physics majors who graduate each year and our program's high ranking among institutions whose graduates go on to receive the Ph.D. in physics.

    Computer simulation is indispensable as a tool for developing control systems to enhance active safety in motor vehicles. In case of complex control concepts, e.g. antiblock systems (ABS), wheel slip control (ASR), or power dynamics control (FDR), simple vehicle models tend to be insufficient. For this reason, the Mechatronics Department of the Gerhard Mercator University - GH Duisburg, in cooperation with Robert Bosch GmbH, developed the development environment FASIM-C++. FASIM-C++ enables three-dimensional power dynamics simulations for complex multibody models of a wide range of vehicle types. As real-time simulation is one of the goals in control system development, consequent application of the methods described here will make the derivation of the equations of motion of complex systems like vehicles more efficient by dispensing with operations which, owing to the vehicle structure, do not affect the results. (orig./AKF) [Deutsch] Zur Entwicklung von Regelsystemen fuer die Erhoehung der aktiven Sicherheit bei Kraftfahrzeugen ist der Einsatz der Rechnersimulation als Entwicklungswerkzeug nicht mehr wegzudenken. Bei komplexen Regelkonzepten, wie dem Antiblockiersystem (ABS), der Antriebsschlupfregelung (ASR) oder der Fahrdynamikregelung (FDR) reichen Ansaetze mit einfachen Fahrzeugmodellen oftmals nicht mehr aus. Aus diesem Grund wird im Fachgebiet Mechatronik der Gerhard-Mercator-Universitaet - GH Duisburg die in Zusammenarbeit mit der Robert Bosch GmbH entstandene Entwicklungsumgebung FASIM-C++ eingesetzt. FASIM-C++ ermoeglicht dreidimensionale Fahrdynamiksimulationen komplexer Mehrkoerpermodelle verschiedenster Fahrzeugtypen. Da im Bereich der Reglerentwicklung Simulationen im Echtzeitbereich angestrebt werden, ermoeglicht die konsequente Anwendung der beschriebenen Vefahren ein effizientes Aufstellen der Bewegungsgleichungen fuer komplexe Mechanismen, wie sie Fahrzeuge darstellen. Auf diese Weise koennen die Operationen entfallen, die aufgrund der
