    Physical environments influence how individuals perceive a space and behave within it. Previous research has revealed deficiencies in ship engine department work environments, and their impact on crew productivity, health and wellbeing. Connect operational task demands to pragmatic physical design and layout solutions by implementing a user-centric perspective. Three focus groups, each consisting of three marine engineers participated in this study. Focus groups were divided into two sessions: first, to investigate the end-user's operational requirements and their relationship with ship physical design and layout. Second, criteria formulated from group discussions were applied to a ship design case study. All focus group sessions were audio recorded and transcribed verbatim. The data were analyzed using Grounded Theory. Design choices made in a ships general arrangement were described to inherently influence how individuals and teams are able to function within the system. Participants detailed logistical relationships between key areas, stressing that the work environment and physical linkages must allow for flexibility of work organization and task execution. Traditional engine control paradigms do not allow effective mitigation of traditional engine department challenges. The influence of technology and modernization of ship systems can facilitate improvement of physical environments and work organization if effectively utilized.

    Recently the Telecom Industry experienced an economic boom & bust cycle that hampered new service development & deployment. Consequently, there are significant problems in capturing key requirements for new network-based services and in educating CIO-IT leaders so they can promote investment proposals with their enterprise business leadership. This paper outlines a multi-functional initiative that Lucent Technologies established to engage and exchange with key Enterprises & their Telecom Suppliers views of future network technologies. This experiment is unique because it is facilitated by the corporate CIO-IT leadership & is focused on the latest 3G wireless technologies. CIO-IT provides externally facing resources that collaborate directly with Enterprises, and Service Providers while facilitating internal interactions with Bell Labs, Business Units and Sales teams. This program embodies a Zen Marketing approach since it seeks to create flashes of enlightenment with IT & business leaders by exercising all the knowledge, culture & behaviors available to an IT end user. The paper summarizes several organizational challenges & benefits uncovered by a program that is focused on transforming Mobility Provider relationships with their customers and expanding the overall awareness of the latest 3G wireless technologies.

    Full Text Available Computer literacy and competitive pressures among end users is increasing day by day due to which the need for End-User Programming in software packages is also increasing for rapid, flexible, and user driven information processing solutions. End User Development out-sources development effort to the end user by enabling software developers to create information systems that can even be adapted by technically inexperienced end users and hence are in great demand. If end user decides to pay the price and add significant programmability to their system, there are additional costs to consider before end user can start to enjoy the payoff. It is important to calculate accurateand early estimation of software size forcalculating effort and cost estimation of software systems incorporating EUD features. With the evolution of object orientation, use cases emerged as a dominant method for structuring requirements. Use cases were integrated into the Unified Modeling Language (UML and Unified Process and became the standard for Software Engineering requirements modelling. The Use Case Point (UCPmethodestimates project size by assigning points to use cases in the same way that Function Point Analysis (FPA assigns points to functions. This paper discusses the concept of end-user programming and Advancement of UCP by adding end-user development/programming as an additional Effort Estimation Factor (EEF.

To achieve its first goal, the thesis presents the findings of a Systematic Mapping Study showing that human factors topics are scarcely and relatively poorly addressed in model transformation research. Motivated by these findings, the thesis explores the requirements of end-user modelers......End-user modelers are domain experts who create and use models as part of their work. They are typically not Software Engineers, and have little or no programming and meta-modeling experience. However, using model manipulation languages developed in the context of Model-Driven Engineering often...... requires such experience. These languages are therefore only used by a small subset of the modelers that could, in theory, benefit from them.

The tool was an early version and the investigation helped the authors to improve it. The investigation showed that users appreciated the simple formula...... language, the coordinated panels, and the drag-and-drop mechanism. However, the most important thing for them was the immediate response when they changed something, for instance part of a formula. The entire visualization was updated immediately without having to switch from development view to production...... view. With uVis, developers construct a visualization from simple visual components such as boxes, curvePoints, and textboxes.

    The paper discusses the ERP adoption based on the IT assimilation theory. The ERP lifecycle is associated with the IT assimilation steps. We propose a distribution of these steps along the lifecycle. Derived from the findings in the reviewed literature we will focus the cultural factors, in particular those related to the end-users (determined as a major impact factor in our previous study: Negovan et al., 2011. Our empirical study is centred on the end-users perspective and it tries to determine if and how their behaviour affects the achievement of the ERP assimilation steps. The paper reasons that organizations that understand the IT assimilation steps correlated to the ERP implementation critical factors are more likely to implement and use ERP successfully.

    2013-01-01

    errors can cause significant losses, even loss of life. Hence, end users are best served when they have performance information relevant to their needs, this paper’s focus. Relative class size (rCS is commonly recognized as a confounding factor in CPD evaluation. Unfortunately, rCS-invariant measures are not easily mapped to end user conditions. We determine a cause of rCS invariance, joint probability table (JPT normalization. JPT normalization means that more end user efficacious measures can be used without sacrificing invariance. An important revelation is that without data normalization, the Matthews correlation coefficient (MCC and information coefficient (IC are not relative class size invariants; this is a potential source of confusion, as we found not all reports using MCC or IC normalize their data. We derive MCC rCS-invariant expression. JPT normalization can be extended to allow JPT rCS to be set to any desired value (JPT tuning. This makes sensitivity analysis feasible, a benefit to both applied researchers and practitioners (end users. We apply our findings to two published CPD studies to illustrate how end users benefit.

    CERNBox is a cloud synchronisation service for end-users: it allows syncing and sharing files on all major mobile and desktop platforms (Linux, Windows, MacOSX, Android, iOS) aiming to provide offline availability to any data stored in the CERN EOS infrastructure. The successful beta phase of the service confirmed the high demand in the community for an easily accessible cloud storage solution such as CERNBox. Integration of the CERNBox service with the EOS storage back-end is the next step towards providing “sync and share” capabilities for scientific and engineering use-cases. In this report we will present lessons learnt in offering the CERNBox service, key technical aspects of CERNBox/EOS integration and new, emerging usage possibilities. The latter includes the ongoing integration of “sync and share” capabilities with the LHC data analysis tools and transfer services.

  18. BEAP: An End-User Agile Programming Paradigm for Business Applications

    Institute of Scientific and Technical Information of China (English)

    Cheng-Chun Shu; Hai-Yan Yu; Hao-Zhi Liu

    2006-01-01

    Business applications are subject to changes with technology trends or market demands. However, quick response to these changes is still a challenging issue. Most of the existing architectures (e.g., CORBA, Web Services) still expose the developers to excessive low-level details and force a tight coupling between program modules. For end users, developing, customizing, and reengineering applications remain difficult and time-consuming tasks. A high-level programming model is presented, together with a descriptive programming paradigm called BEAP, to facilitate end-user programming. In this approach, applications could be visually composed from well-defined software components called "funnels" in an event-driven fashion. Application examples have shown that, by raising the level of abstraction as well as simplifying the programming model, BEAP could empower end users to build business applications on demand with improved productivity.

    2007-01-01

    End-user informatics applications are Internet data web management automation solutions. These are mass modeling and mass management collaborative communal consensus solutions. They are made and maintained by managerial, professional, technical and specialist end-users. In end-user informatics the end-users are always right. So it becomes necessary for information technology professionals to understand information and informatics from the end-user perspective. End-user informatics starts with the observation that practical prose is a mass consensus communal modeling technology. This high technology is the mechanistic modeling medium we all use every day in all of our practical pursuits. Practical information flows are the lifeblood of modern capitalist communities. But what exactly is practical information? It's ultimately physical information, but the physics is highly emergent rather than elementary. So practical reality is just physical reality in deep disguise. Practical prose is the medium that we all us...

    2014-01-01

    Full Text Available End users will play a crucial role in up-coming smart grids that aim to link end-users and energy providers in a better balanced and more efficient electricity system. Within this context, this paper aims to deliver a coherent view on current good practice in end-user engagement in smart grid projects. It draws from a recent review of theoretical insights from sustainable consumption behaviour, social marketing and innovation systems and empirical insights from recent smart grid projects to create an inventory of common motivators, enablers and barriers of behavioural change, and the end-user engagement principles that can be derived from that. We conclude with identifying current research challenges as input for a research agenda on end-user engagement in smart grids.

    Objectives Despite extensive research into the determinants of electronic nicotine delivery system (ENDS) uptake, few studies have examined the psychosocial benefits ENDS users seek and experience. Using a consumer ritual framework, we explored how ENDS users recreated or replaced smoking practices, and considered implications for smoking cessation. Design In-depth interviews; data analysed using thematic analysis. Setting Dunedin, New Zealand. Participants 16 young adult ENDS users (age M=21.4, SD=1.9; 44% female). Results Participants reported using different ENDS to achieve varying outcomes. Some used ‘cigalikes’ to recreate a physically and visually similar experience to smoking; they privileged device appearance over nicotine delivery. In contrast, others used personally crafted mods to develop new rituals that differentiated them from smokers and showcased their technical expertise. Irrespective of the device they used, several former smokers and dual users of cigarettes and ENDS experienced strong nostalgia for smoking attributes, particularly the elemental appeal of fire and the finiteness of a cigarette. Non-smoking participants used ENDS to maintain social connections with their peers. Conclusions Participants used ENDS to construct rituals that recreated or replaced smoking attributes, and that varied in the emphasis given to device appearance, nicotine delivery, and social performance. Identifying how ENDS users create new rituals and the components they privilege within these could help promote full transition from smoking to ENDS and identify those at greatest risk of dual use or relapse to cigarette smoking.

    Breath research is now well established and is solving some of the applications in the area of identifying volatiles for medical diagnosis. This paper looks at how this research has been taken to an end-user market. It is not intended to be an indepth study of the science but simply to draw attention to the role of the commercial link between the researcher and end-user. This market is not only in research but exists in hospitals, clinics, sports medicine and even homecare. The link between research and the end-user market is a vital one to avoid breath analysis being the tool of researchers only. The ubiquitous use of breath analysis depends upon it. This is a review of some of the success stories in commercializing the important breath analysis research that has been conducted over the last few decades. In order to make breath analysis the new blood test, products that have end-user appeal need to be developed and routes to market established.

  13. A Formalization of the End User Service Development Approach

    Directory of Open Access Journals (Sweden)

    Meriem Benhaddi

    2013-01-01

    Full Text Available The end user service development known as the user-centric SOA emerged as a new approach that allows giving the end user the ability to create on the fly his own applications that meet a situational need. In fact, the classical SOA was designed for developers and is characterized by a heavy technical stack which is out of reach of end users. Lightweight Web 2.0 technologies such as Mashup appeared to bridge this gap and provide a new agile and quick way to compose and integrate different resources in a dynamic and on the fly manner. However, Mashups are emerging applications, and thus consist of immature, non intuitive and non formalized area. In this paper, we formalize the user-centric SOA development by proposing a new cloud-based architecture for user-centric SOA platforms, and by introducing a new rich integration language based on the advanced Enterprise Integration Patterns (EIPS. We also propose a new intuitive and self-explanatory semantic process for end users services integration.

  15. Model for Predicting End User Web Page Response Time

    CERN Document Server

    Nagarajan, Sathya Narayanan

    2012-01-01

    Perceived responsiveness of a web page is one of the most important and least understood metrics of web page design, and is critical for attracting and maintaining a large audience. Web pages can be designed to meet performance SLAs early in the product lifecycle if there is a way to predict the apparent responsiveness of a particular page layout. Response time of a web page is largely influenced by page layout and various network characteristics. Since the network characteristics vary widely from country to country, accurately modeling and predicting the perceived responsiveness of a web page from the end user's perspective has traditionally proven very difficult. We propose a model for predicting end user web page response time based on web page, network, browser download and browser rendering characteristics. We start by understanding the key parameters that affect perceived response time. We then model each of these parameters individually using experimental tests and statistical techniques. Finally, we d...

    This paper presents the Cloud4all Service Synthesizer Tool, a framework that enables efficient orchestration of accessibility services, as well as their combination into complex forms, providing more advanced functionalities towards increasing the accessibility of end-users with various types of functional limitations. The supported services are described formally within an ontology, enabling, thus, semantic service composition. The proposed service composition approach is based on semantic matching between services specifications on the one hand and user needs/preferences and current context of use on the other hand. The use of automatic composition of accessibility services can significantly enhance end-users' accessibility, especially in cases where assistive solutions are not available in their device.

    Full Text Available Official and/or public archives were a byproduct of colonial rule in Africa. (Archives are a byproduct of administrative governance everywhere. Given the density and diversity of colonial archival records, historians have tended to rely on them for the study of the colonial period. Publications on the use of archives have not captured the perspective of end-users, who often face peculiar challenges in the use of colonial and metropolitan archives. This paper provides an end-user perspective on colonial archives in Nigeria and the United Kingdom. It highlights the challenges of data collection and prospects of optimal use of archival source material. The discussion is of general application to users of colonial archives especially in the former British colonies in Africa.

Examples of this enriched content are: virtual edits that allow the order of presentation within the content to be changed or that allow the content to be subsetted; conditional text, graphic or video objects that can be placed to appear within content and triggered by viewer interaction; additional navigation links that can be added to structure how other users view the base content object. The enriched content can be viewed directly within the context of the TV viewing experience. It may also be shared with other users within a distributed peer group. Our architecture is based on a model that allows the original content to remain unaltered, and which respects DRM restrictions on content reuse. The fundamental approach we use is to define an intermediate content enhancement layer that is based on the W3C′s SMIL language. Using a pen-based enhancement interface, end-users can manipulate content that is saved in a home PDR setting. This paper describes our architecture and it provides several examples of how our system handles content enhancement. We also describe a reference implementation for creating and viewing enhancements.

    these guidelines. VMTL draws on our previous work on the usability-oriented Visual Model Query Language. We implement VMTL using the Henshin model transformation engine, and empirically investigate its learnability via two user experiments and a think-aloud protocol analysis. Our experiments, although conducted...... on computer science students exhibiting only some of the characteristics of end-user modelers, show that VMTL compares favorably in terms of learnability with two state-of the-art model transformation languages: Epsilon and Henshin. Our think-aloud protocol analysis confirms many of the design decisions......Model transformation is a key enabling technology of Model-Driven Engineering (MDE). Existing model transformation languages are shaped by and for MDE practitioners—a user group with needs and capabilities which are not necessarily characteristic of modelers in general.

    Full Text Available Online shopping sites have recently gained momentum in India. Since the ecommerce industry is in infancy state, customer (end user satisfaction with the online shopping is the prime concern because decreasing customer satisfaction leads to negative electronic word of mouth (eWOM which is very severe for the business. Through a dataset gathered from 127 online shopping customers in with respect to online shopping sites in India, this study investigates the role of website quality, information integrity and perceived behavioral control on customers’ online experience, which in turn influences usage and satisfaction. One of the key results is that the online customer experience has a larger influence on satisfaction rather than usage.

  4. Analyses Of Two End-User Software Vulnerability Exposure Metrics

    Energy Technology Data Exchange (ETDEWEB)

    Jason L. Wright; Miles McQueen; Lawrence Wellman

    2012-08-01

    The risk due to software vulnerabilities will not be completely resolved in the near future. Instead, putting reliable vulnerability measures into the hands of end-users so that informed decisions can be made regarding the relative security exposure incurred by choosing one software package over another is of importance. To that end, we propose two new security metrics, average active vulnerabilities (AAV) and vulnerability free days (VFD). These metrics capture both the speed with which new vulnerabilities are reported to vendors and the rate at which software vendors fix them. We then examine how the metrics are computed using currently available datasets and demonstrate their estimation in a simulation experiment using four different browsers as a case study. Finally, we discuss how the metrics may be used by the various stakeholders of software and to software usage decisions.

    Stanford University's Knowledge Systems Laboratory (KSL) is working in partnership with Battelle Memorial Institute and IBM Watson Research Center to develop a suite of technologies for information extraction, knowledge representation & reasoning, and human-information interaction, in unison entitled 'Knowledge Associates for Novel Intelligence' (KANI). We have developed an integrated analytic environment composed of a collection of analyst associates, software components that aid the user at different stages of the information analysis process. An important part of our participatory design process has been to ensure our technologies and designs are tightly integrate with the needs and requirements of our end users, To this end, we perform a sequence of evaluations towards the end of the development process that ensure the technologies are both functional and usable. This paper reports on that process.

  6. Ideas on a system design for end-user robots

    Science.gov (United States)

    Bonasso, R. P.; Slack, Marc G.

    1992-11-01

    Robots are being used successfully in factory automation; however, recently there has been some success in building robots which can operate in field environments, where the domain is less predictable. New perception and control techniques have been developed which allow a robot to accomplish its mission while dealing with natural changes in both land and underwater environments. Unfortunately, efforts in this area have resulted in many one-of-a-kind robots, limited to research laboratories or carefully delimited field task arenas. A user who would like to apply robotic technology to a particular field problem must basically start from scratch. The problem is that the robotic technology (i.e., the hardware and software) which might apply to the user's domain exists in a diverse array of formats and configurations. For end-user robots to become a reality, an effort to standardize some aspects of the robotic technology must be made, in much the same way that personal computer technology is becoming standardized. Presently, a person can buy a computer and then acquire hardware and software extensions which simply `plug in' and provide the user with the required utility without the user having to understand the inner workings of the pieces of the system. This technology even employs standardized interface specifications so the user is presented with a familiar interaction paradigm. This paper outlines some system requirements (hardware and software) and a preliminary design for end-user robots for field environments, drawing parallels to the trends in the personal computer market. The general conclusion is that the appropriate components as well as an integrating architecture are already available, making development of out-of-the- box, turnkey robots for a certain range of commonly required tasks a potential reality.

  7. The Effects of Normalisation of the Satisfaction of Novice End-User Querying Databases

    Directory of Open Access Journals (Sweden)

    Conrad Benedict

    1997-05-01

    Full Text Available This paper reports the results of an experiment that investigated the effects different structural characteristics of relational databases have on information satisfaction of end-users querying databases. The results show that unnormalised tables adversely affect end-user satisfaction. The adverse affect on end-user satisfaction is attributable primarily to the use of non atomic data. In this study, the affect on end user satisfaction of repeating fields was not significant. The study contributes to the further development of theories of individual adjustment to information technology in the workplace by alerting organisations and, in particular, database designers to the ways in which the structural characteristics of relational databases may affect end-user satisfaction. More importantly, the results suggest that database designers need to clearly identify the domains for each item appearing in their databases. These issues are of increasing importance because of the growth in the amount of data available to end-users in relational databases.

    Spreadsheets are widely used, and studies have shown that most end-user spreadsheets contain nontrivial errors. To improve end-users productivity, recent research proposes the use of a model-driven engineering approach to spreadsheets. In this paper we conduct the first systematic empirical study to assess the effectiveness and efficiency of this approach. A set of spreadsheet end users worked with two different model-based spreadsheets, and we present and analyze here the results achieved.

    2017-01-01

    Full Text Available An end-user has the main role in the creation of space where spends most of its lifetime (home, workplace. That is why important that a designer (he first recognizes what requests of the end-user are. In the reference literature and researches that deal with the spatial organisations and designing of living area, the role of an end-user is essential. However, what does the end user participation mean, actually? At what level an end-user makes a final decision? Is it a choice among several alternative solutions provided by an architect or end-user himself? This article precisely deals with that subject - where begins and where ends participation of the end-user when the theme is the final spatial solution and under what circumstances. In this case, habitation represents the much more sensitive area than any other area for human needs or activities. In technical terms, an end-user could be someone who either knows nothing or knows a lot but not enough about both the spatial and functional organisations. His role should be reduced to choice of one from the group of high-quality solutions and, in a technical sense, logical solutions made by an expert. No more than that.

    Although many web-based mental health interventions are being released, the actual uptake by end users is limited. The marginal level of engagement of end users when developing these interventions is recognized as an important cause for uptake problems. In this paper, we offer our perceptive on how to improve user engagement. By doing so, we aim to stimulate a discourse on user involvement within the field of online mental health interventions. We shortly describe three different methods (the expert-driven method, intervention mapping, and scrum) that were currently used to develop web-based health interventions. We will focus to what extent the end user was involved in the developmental phase, and what the additional challenges were. In the final paragraph, lessons learned are summarized, and recommendations provided. Every method seems to have its trade-off: if end users are highly involved, availability of end users and means become problematic. If end users are less actively involved, the product may be less appropriate for the end user. Other challenges to consider are the funding of the more active role of technological companies, and the time it takes to process the results of shorter development cycles. Thinking about user-centered design and carefully planning, the involvement of end users should become standard in the field of web-based (mental) health. When deciding on the level of user involvement, one should balance the need for input from users with the availability of resources such as time and funding.

    2012-01-01

    An increasing number of retail energy markets exhibit price fluctuations and provide customers such as data centers and residential users the opportunity to buy energy at lower than average prices. Such cost savings however are hard to obtain in practice because they require users to observe the price fluctuations and shift their consumption to low price periods. We propose to use energy storage to allow users to satisfy demand at times when prices are high with energy previously bought during low-price periods. We investigate how to control the battery to minimize energy costs, subject to fluctuating prices and user demand. We formulate this problem as a Markov Decision Process and show that the optimal policy has a threshold structure. We then numerically compute the thresholds using real-world traces from existing energy markets. We show that energy storage using this policy leads to significant cost savings, and study the impact of the battery size on the optimal policy and the potential savings.

    Full Text Available It is common for end-users to have difficulty in using computer or network security appropriately and thus have often been ridiculed when misinterpreting instructions or procedures. This discussion paper details the outcomes of research undertaken over the past six years on why security is overly complex for end-users. The results indicate that multiple issues may render end-users vulnerable to security threats and that there is no single solution to address these problems. Studies on a small group of senior citizens has shown that educational seminars can be beneficial in ensuring that simple security aspects are understood and used appropriately.

    Full Text Available End-user programming (EUP is a common approach for helping ordinary people create small programs for their professional or daily tasks. Since end-users may not have programming skills or strong motivation for learning them, tools should provide what end-users want with minimal costs of learning –i.e., they must decrease the barriers to entry. However, it is often hard to address these needs, especially for fast-evolving domains such as the Web. To better understand these existing and ongoing challenges, we conducted two formative studies with Web users –a semi-structured interview study, and a Wizard-of-Oz study. The interview study identifies challenges that participants have with their daily experiences on the Web. The Wizard-of-Oz study investigates how participants would naturally explain three computational tasks to an interviewer acting as a hypothetical computer agent. These studies demonstrate a disconnect between what end-users want and what existing EUP systems support, and thus open the door for a path towards better support for end user needs. In particular, our findings include: (1 analysis of challenges that end-users experience on the Web with solutions; (2 seven core functionalities of EUP for addressing these challenges; (3 characteristics of non-programmers describing three common computation tasks; (4 design implications for future EUP systems.

    Full Text Available There is an urgent need of solutions for end user data protection and privacy during the times when migrating from one cloud service provider to another. This paper reviews the challenges in cloud computing services regarding end user data, analyzing the issues and presented solutions to overcome them. The end user data required to be protected in four different ways ranging from usage data which is the information collected from computer systems, the second is the sensitive information on health and bank accounts, third is the personally identifiable information; information to identify an individual and finally is the unique device identity information that is uniquely traceable like IP addresses, unique hardware identities (media access control (MAC address. By using solution paths such as digital keys, multi factor authentication and cloud aware applications. This paper identifies end users data security issues when using cloud computing services. The focus is directed to critical issues related to unauthorized access for integrity during data in transit. It can be addressed using public key cryptography or public key infrastructure (PKI for confidentiality and data integrity of end user data over the cloud. Then for migrating from one cloud service provider to another, data security and privacy are addressed by cloud aware applications. Lastly, using multi factor authentication combined with network and application detection systems, intrusion detection systems and network traffic routing in case of cyber-attacks, can help in denial of service attack mitigation or prevent man in the middle and network snooping attacks in cloud computing.

    2008-01-01

    Very little is known about the process by which end-user developers detect and correct spreadsheet errors. Any research pertaining to the development of spreadsheet testing methodologies or auditing tools would benefit from information on how end-users perform the debugging process in practice. Thirteen industry-based professionals and thirty-four accounting & finance students took part in a current ongoing experiment designed to record and analyse end-user behaviour in spreadsheet error detection and correction. Professionals significantly outperformed students in correcting certain error types. Time-based cell activity analysis showed that a strong correlation exists between the percentage of cells inspected and the number of errors corrected. The cell activity data was gathered through a purpose written VBA Excel plug-in that records the time and detail of all cell selection and cell change actions of individuals.

    The National Integrated Medical Imaging System (NIMIS) is used to store and retrieve medical imaging studies in Ireland. The purpose of this audit was to obtain feedback from its end-users in relation to key NIMIS functionality and to understand their perception of its existing interface while identifying potential improvements. The results showed that, while the majority of respondents are satisfied with NIMIS, they identified a number of areas of concern. These included difficulty in identifying the appropriate code for a study, 88 (34%); dissatisfaction with ordering and viewing scans, 82 (32%); and a need for improved communication between end-users and local Radiology departments, with 104 (40%) unsure when to contact the department and 137 (53%) dissatisfied with the feedback they received in relation to requests. Respondents indicated that addressing these issues would improve the NIMIS end-user experience while allowing it to continue to meet current and future clinical needs.

    Public mandate to control cost, while improving quality of service, leads health care administrators to look to information technology for innovative solutions. This case study of acute care registered nurses in a public hospital focuses on experiences of the end-users of a computerized medication system. Data was obtained by in-depth interviews and observation performed in the clinical setting. Findings fell into five challenging issues to the end-user and health care administration: end-user perceptions of inadequate training, negative experiences of implementation, perceived deficiencies in quality of technology, perceptions of lack of participatory design and a ensuing circumvention of the new system. Emphasis is on the relationship of the findings to the quality of public health care administration.

    2017-01-01

    This paper describes the development of a questionnaire for evaluating usability during EHR system procurement (DPUQ). Established usability questionnaires can be used to gather user feedback after using the systems. However, during procurement, experimenting with real system use is practical only with a limited number of system candidates. There is a need for less resource-demanding usability evaluation in the early stages of procurement in cases with several vendors. DPUQ has been designed for usability evaluation by end-users during special scenario-based vendor demonstrations. The questionnaire includes three sets of questions to be used during and after the vendor demonstration. DPUQ delivers specific usability scores and can be used to compare system candidates in procurement complementing other evaluation methods.

    2012-01-01

    Cross-smart space applications are specific types of software services that enable users to share information, monitor the physical and logical surroundings and control it in a way that is meaningful for the user's situation. For developing cross-smart space applications, this paper makes two main contributions: it introduces (i) a component design and scripting method for end-user programming of cross-smart space applications and (ii) a backend framework of components that interwork to support the brunt of the RDFScript translation, and the use and execution of ontology models. Before end-user programming activities, the software professionals must develop easy-to-apply Driver components for the APIs of existing software systems. Thereafter, end-users are able to create applications from the commands of the Driver components with the help of the provided toolset. The paper also introduces the reference implementation of the framework, tools for the Driver component development and end-user programming of cross-smart space applications and the first evaluation results on their application.

    2017-01-01

    In this study we explore the seasonal predictability of water resources in a Mediterranean environment (the Boadella reservoir, in north-eastern Spain). Its utility for end-users is assessed through the analysis of economic value curve areas (EVA). Firstly, we have built monthly multiple linear regression (MLR) models for the in-flow, out-flow and volume anomalies by identifying the underlying relationships between these predictands and their potential predictors, both meteorological and human influenced: rainfall, maximum and minimum temperatures, reservoir volume and discharge. Subsequently, we have forecast the monthly anomalies with these models for the period 1981-2010 (up to seven months ahead). We have tested the aforementioned models with four strategies in a leave-one-out cross-validation procedure (LOOCV): a) Climatology (Clim.), b) persistence (Pers.), c) antecedent observations+climatology (A+Clim.), d) antecedent observations+European Centre for Medium-range Weather Forecasts (ECMWF) System 4 anomalies (A+S4). Climatology is the operational strategy against which the other approximations are compared. The second and third approaches only use observations as input data. Finally, the last one combines both observations and ECMWF System 4 forecasts. The LOOCV revealed that reservoir volume is the variable best described by the MLR models, followed by in-flow and out-flow anomalies. In the case of volume anomalies, the predictability displayed provides added value with respect to climatology with a minimum of four months in advance. For in-flow and out-flow this is true at one month ahead, and regarding the latter variable we encounter enhanced predictability also at longer horizons for the summer months, when water demands peak (a valuable result for end-users). Hence, there is a window of opportunity to develop future operational frameworks that could outperform the use of climatology for these variables and forecast horizons. Copyright © 2016

  15. A content validity approach to creating an end-user computer skill assessment tool

    Directory of Open Access Journals (Sweden)

    Shirley Gibbs

    Full Text Available Practical assessment instruments are commonly used in the workplace and educational environments to assess a person\\'s level of digital literacy and end-user computer skill. However, it is often difficult to find statistical evidence of the actual validity of instruments being used. To ensure that the correct factors are being assessed for a particular purpose it is necessary to undertake some type of psychometric testing, and the first step is to study the content relevance of the measure. The purpose of this paper is to report on the rigorous judgment-quantification process using panels of experts in order to establish inter-rater reliability and agreement in the development of end-user instruments developed to measure workplace skills using spreadsheet and word-processing applications.

    2000-04-11

    A meeting was held in Santa Fe, New Mexico, October 21--22, 1999, to generate discussion and consensus about interoperability of publicly available scholarly information archives. The invitees represented several well known e-print and report archive initiatives, as well as organizations with interests in digital libraries and the transformation of scholarly communication. The central goal of the meeting was to agree on recommendations that would make the creation of end-user services--such as scientific search engines and linking systems--for data originating from distributed and dissimilar archives easier. The Universal Preprint Service (UPS) Prototype was developed in preparation for this meeting. As a proof-of-concept of a multi-discipline digital library of publicly available scholarly material, the Prototype harvested nearly 200,000 records from several different archives and created an attractive end-user environment. This paper describes the results of the project. This is done in two ways. On the one hand, the experimental end-user service that was created during the project is illustrated. On the other hand, the lessons that the project team drew from the experience of creating the Prototype are presented.

    Mouillet, E

    1999-01-01

    OBJECTIVE: A study was conducted to determine if bibliographic retrieval performed by French-speaking end users is impaired by English language interfaces. The American database MEDLINE on CD-ROM was used as a model. METHODS: A survey of self-administered questionnaires was performed at two libraries of Victor Segalen Bordeaux 2 University, during a two-month period in 1997. Three study groups were constituted: MEDLINE / Ovid end users, MEDLINE / Ovid librarian-mediated users, and Pascal, a French bibliographic database, end users. RESULTS: Among 191 respondents, only 22% thought English was an obstacle to their bibliographic retrieval. However, the research software was generally underused and the quality of the retrieval weak. The differences were statistically significant between users trained by librarians and the self-trained group, the former performing better. CONCLUSION: Special efforts need to be made to develop curriculum training programs for computerized bibliographic retrieval in medical schools, regardless of the native language of the student.

    2013-01-01

    The criteria for which data acquiring software and its supporting infrastructure should be designed should take the following two points into account: the reusability and organization of stored online and remote data and content, and an assessment on whether abandoning a platform optimized design in favor for a multi-platform solution significantly reduces the performance of an end-user application. Furthermore, in-house applications that control or process instrument acquired data for end-users should be designed with a communication and control interface such that the application's modules can be reused as plug-in modular components in greater software systems. The application of the above mentioned is applied using two loosely related projects: a mobile application, and a website containing live and simulated data. For the intelligent devices mobile application AIDM, the end-user interface have a platform and data type optimized design, while the database and back-end applications store this information in an organized manner and manage access to that data to only to authorized user end application(s). Finally, the content for the website was derived from a database such that the content can be included and uniform to all applications accessing the content. With these projects being ongoing, I have concluded from my research that the applicable methods presented are feasible for both projects, and that a multi-platform design for the mobile application only marginally drop the performance of the mobile application.

    1989-01-01

    This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership.

    2016-03-01

    Full Text Available Every day, each active social network user produces and shares texts, images and videos. While developers can access such data through application programming interfaces (APIs for creating games, visualizations and routines, end users have less control on such information. Their access is mediated by the social application features, which limits them in combining sources, filtering results and performing actions on groups of elements. In order to fill this gap, we introduce FaceMashup, an end user development (EUD environment supporting the manipulation of the Facebook graph. We describe the tool interface, documenting the choices we made during the design iterations. Data types are represented through widgets containing user interface (UI elements similar to those used in the social network application. Widgets can be connected with each other with the drag and drop of their inner fields, and the application updates their content. Finally, we report the results of a user-test on the FaceMashup prototype, which shows a good acceptance of the environment by end-users.

  13. The Integrated Nordic End-User Electricity Market - Feasibility and identified obstacles

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2006-02-15

    The report identifies the various obstacles that currently exist which prevent the formation of a truly integrated Nordic electricity end-user market. The obstacles have been divided into three categories: technical, regulatory and commercial. NordREG proposes that to further integrate the Nordic end-user electricity markets, a number of differences of technical, legal and market nature ought to be gradually harmonized in order to facilitate market entry and cross-border trade. Technical obstacles: Especially the following problems related to the data and metering systems should be solved: Transferred messages, information and message timing should be harmonised; Message format should be decided; A common data transmission protocol should be specified. New solutions like web-based solutions should be studied; The identification of the final customers' metering point should be harmonised. Regulatory obstacles: The identified regulatory obstacles relate to three areas, namely the division of tasks between monopoly and competitive activities, the operation and duties of distribution network operators including how these are regulated, and the legal framework to provide protection for small end users. On the basis of the review of regulatory obstacles, the following recommendations are made: The principles of neutrality and the way these principles are being supervised by the regulator is a key issue to improve the functioning of the Nordic end-user market. Regulators should seek to harmonise regulation on neutrality and put it high on the agenda in a forthcoming process of market integration; The procedures for switching supplier should be as smooth, easy and quick as possible. It is also important that suppliers, especially the new market entrants, can participate in reliable, transparent and fluent switching practices, since this lowers the threshold for entering other than domestic electricity market. The switching model should be harmonised for the Nordic end-user

    Kiehle, Christian; Poth, Andreas

    2010-05-01

    The open source software framework deegree is a comprehensive implementa­tion of standards as defined by ISO and Open Geospatial Consortium (OGC). It has been developed with two goals in mind: provide a uniform framework for implementing Spatial Data Infrastructures (SDI) and adhering to standards as strictly as possible. Although being open source software (Lesser GNU Public Li­cense, LGPL), deegree has been developed with a business model in mind: providing the general building blocks of SDIs without license fees and offer cus­tomization, consulting and tailoring by specialized companies. The core of deegree is a comprehensive Java Application Programming Inter­face (API) offering access to spatial features, analysis, metadata and coordinate reference systems. As a library, deegree can and has been integrated as a core module inside spatial information systems. It is reference implementation for several OGC standards and based on an ISO 19107 geometry model. For end users, deegree is shipped as a web application providing easy-to-set-up components for web mapping and spatial analysis. Since 2000, deegree has been the backbone of many productive SDIs, first and foremost for governmental stakeholders (e.g. Federal Agency for Cartography and Geodesy in Germany, the Ministry of Housing, Spatial Planning and the En­vironment in the Netherlands, etc.) as well as for research and development projects as an early adoption of standards, drafts and discussion papers. Be­sides mature standards like Web Map Service, Web Feature Service and Cata­logue Services, deegree also implements rather new standards like the Sensor Observation Service, the Web Processing Service and the Web Coordinate Transformation Service (WCTS). While a robust background in standardization (knowledge and implementation) is a must for consultancy, standard-compliant services and encodings alone do not provide solutions for customers. The added value is comprised by a sophistic­ated set of

    Low-cost sensor technology can potentially revolutionise the area of air pollution monitoring by providing high-density spatiotemporal pollution data. Such data can be utilised for supplementing traditional pollution monitoring, improving exposure estimates, and raising community awareness about air pollution. However, data quality remains a major concern that hinders the widespread adoption of low-cost sensor technology. Unreliable data may mislead unsuspecting users and potentially lead to alarming consequences such as reporting acceptable air pollutant levels when they are above the limits deemed safe for human health. This article provides scientific guidance to the end-users for effectively deploying low-cost sensors for monitoring air pollution and people's exposure, while ensuring reasonable data quality. We review the performance characteristics of several low-cost particle and gas monitoring sensors and provide recommendations to end-users for making proper sensor selection by summarizing the capabilities and limitations of such sensors. The challenges, best practices, and future outlook for effectively deploying low-cost sensors, and maintaining data quality are also discussed. For data quality assurance, a two-stage sensor calibration process is recommended, which includes laboratory calibration under controlled conditions by the manufacturer supplemented with routine calibration checks performed by the end-user under final deployment conditions. For large sensor networks where routine calibration checks are impractical, statistical techniques for data quality assurance should be utilised. Further advancements and adoption of sophisticated mathematical and statistical techniques for sensor calibration, fault detection, and data quality assurance can indeed help to realise the promised benefits of a low-cost air pollution sensor network.

  17. Analysis of error introduced during end-user post-processing of airborne laser data (lidar)

    Science.gov (United States)

    Smith, Sarah Louise

    The primary aims and objectives of this thesis are to identify the sources and operation of the errors which are introduced during end-user post-processing of airborne laser scanning data. Previous research has concentrated on the errors incorporated during data capture and preliminary supplier processing. The errors which are introduced by the end-users have been largely neglected. As a result, data users cannot currently estimate the errors within, and therefore the quality of, the models they produce. Laser scanning is a remote sensing technique for the capture of height data of the surface of the Earth. It offers competitive capture costs, high accuracy, and is particularly suited to capturing information in complex urban areas. As a result the commercial value of laser scanning data is high. However, in order to realise the potential of this technique, the quality of the datasets derived from the data must be assessed and the errors introduced during modelling understood. For users to make informed decisions regarding the design of their post-processing workflow it is fundamental that they know how and where errors may be introduced. The characteristics of these errors are investigated in this thesis using a range of approaches. End-user post-processing is divided into three techniques in the thesis: data structuring, filtering and segmentation. Each process is investigated hi terms of accuracy and sensitivity, through the comparison of several methods with reference models. New algorithms for filtering and segmenting laser data are presented. The errors created by each process are identified and analysed. The location of errors across the elevation surface are also investigated. It is shown how this information could be used to aid end-users design their post-processing methodology. The methodology for analyzing the errors is presented as a framework which could be used as a standard for ALS models. This thesis shows that the choice of post

    Josef Faller

    Full Text Available Co-adaptive training paradigms for event-related desynchronization (ERD based brain-computer interfaces (BCI have proven effective for healthy users. As of yet, it is not clear whether co-adaptive training paradigms can also benefit users with severe motor impairment. The primary goal of our paper was to evaluate a novel cue-guided, co-adaptive BCI training paradigm with severely impaired volunteers. The co-adaptive BCI supports a non-control state, which is an important step toward intuitive, self-paced control. A secondary aim was to have the same participants operate a specifically designed self-paced BCI training paradigm based on the auto-calibrated classifier. The co-adaptive BCI analyzed the electroencephalogram from three bipolar derivations (C3, Cz, and C4 online, while the 22 end users alternately performed right hand movement imagery (MI, left hand MI and relax with eyes open (non-control state. After less than five minutes, the BCI auto-calibrated and proceeded to provide visual feedback for the MI task that could be classified better against the non-control state. The BCI continued to regularly recalibrate. In every calibration step, the system performed trial-based outlier rejection and trained a linear discriminant analysis classifier based on one auto-selected logarithmic band-power feature. In 24 minutes of training, the co-adaptive BCI worked significantly (p = 0.01 better than chance for 18 of 22 end users. The self-paced BCI training paradigm worked significantly (p = 0.01 better than chance in 11 of 20 end users. The presented co-adaptive BCI complements existing approaches in that it supports a non-control state, requires very little setup time, requires no BCI expert and works online based on only two electrodes. The preliminary results from the self-paced BCI paradigm compare favorably to previous studies and the collected data will allow to further improve self-paced BCI systems for disabled users.

    The Objective Supply Capability Adaptive Redesign (OSCAR) project is designed to identify and develop programs which automate requirements not included in standard army systems. This includes providing automated interfaces between standard army systems at the National Guard Bureau (NGB) level and at the state/territory level. As part of the OSCAR project, custom software has been installed at NGB to streamline management of major end items. This software allows item managers to provide automated disposition on excess equipment to states operating the Standard Army Retail Supply System Objective (SARSS-O). It also accelerates movement of excess assets to improve the readiness of the Army National Guard (ARNG)--while reducing excess on hand. The purpose of the End-User Manual is to provide direction and guidance to the customer for implementing the ARNG Excess Management Program.

    2014-06-01

    Full Text Available Recent disasters have shown that having clearly defined preventive procedures and decisions is a critical component that minimizes evacuation hazards and ensures a rapid and successful evolution of evacuation plans. In this context, we present our Situation-Aware System for enhancing Evacuation Plans (SASEP system, which allows creating end-user business rules that technically support the specific events, conditions and actions related to evacuation plans. An experimental validation was carried out where 32 people faced a simulated emergency situation, 16 of them using SASEP and the other 16 using a legacy system based on static signs. From the results obtained, we compare both techniques and discuss in which situations SASEP offers a better evacuation route option, confirming that it is highly valuable when there is a threat in the evacuation route. In addition, a study about user satisfaction using both systems is presented showing in which cases the systems are assessed as satisfactory, relevant and not frustrating.

    In this paper, the authors present the results of a qualitative case-study seeking to characterize data discovery needs and barriers of principal investigators and research support staff in clinical translational science. Several implications for designing and implementing translational research systems have emerged through the authors' analysis. The results also illustrate the benefits of forming early partnerships with scientists to better understand their workflow processes and end-user computing practices in accessing data for research. The authors use this user-centered, iterative development approach to guide the implementation and extension of i2b2, a system they have adapted to support cross-institutional aggregate anonymized clinical data querying. With ongoing evaluation, the goal is to maximize the utility and extension of this system and develop an interface that appropriately fits the swiftly evolving needs of clinical translational scientists.

    2016-06-01

    Full Text Available In the UK, the transparency agenda is forcing data stewardship organisations to review their dissemination policies and to consider whether to release data that is currently only available to a restricted community of researchers under licence as open data. Here we describe the results of a study providing evidence about the risks of such an approach via a simulated attack on two social survey datasets. This is also the first systematic attempt to simulate a jigsaw identification attack (one using a mashup of multiple data sources on an anonymised dataset. The information that we draw on is collected from multiple online data sources and purchasable commercial data. The results indicate that such an attack against anonymised end user licence (EUL datasets, if converted into open datasets, is possible and therefore we would recommend that penetration tests should be factored into any decision to make datasets (that are about people open.

    2006-09-18

    The hydrogen and fuel cell (HFC) technologies industry is an emerging market with several barriers to overcome. This paper provided details of a research project undertaken to better understand the needs of hydrogen end-users and suppliers with regard to insurance for their projects. A total of 14 interviews were conducted with end-users and insurance industry representatives. Results indicated that HFC industry respondents did not have enough knowledge or experience of the insurance industry to answer the questions asked of them, in any detail or at all. Insurance industry respondents were aware of the HFC industry's lack of understanding of the insurance industry. It was noted that both groups wish to resolve communication gaps between the 2 industries, and that the development of a mechanism for appropriate communications may resolve misunderstandings. It was suggested that the HFC industry needs to develop a general knowledge of insurance issues as they relate to their industry and a comprehensive understanding of the insurance industry's procedural needs. The HFC industry must also work to educate insurance providers about hydrogen and its safety record. It was suggested that the Canadian Transportation Fuel Cell Alliance (CTFCA) should take a role in educating the insurance industry about hydrogen. It was concluded that despite the lack of understanding and knowledge on the part of the HFC respondents, the study was useful in identifying the nature and depth of the problem, and had validated the input received from the insurance industry respondents. An appendix of study materials was included.

  9. Quality and Performance of LED Flashlights in Kenya: Common End User Preferences and Complaints

    2009-09-14

    Flashlights that use LED technology have quickly emerged as the dominant source of portable lighting in Kenya. While flashlights do not normally provide a substitute for kerosene and other highly inefficient fuels, they are an important early manifestation of LED lighting in the developing world that can serve as a platform - or deterrent - to the diffusion of the technology into the broader off-grid lighting market. The lead acid batteries embedded in flashlights also represent an important source of hazardous waste, and flashlight durability is thus an important determinant of the rate of waste disposal. Low-cost LED flashlights with prices from $1 to $4 are now widely available in shops and markets throughout Kenya. The increased penetration of LED technology in the flashlight market is significant, as over half of all Kenyan households report owning a flashlight (Kamfor, 2002). While this shift from conventional incandescent technology to modern LEDs may appear to be a promising development, end users that our research team interviewed expressed a number of complaints about the quality and performance of these new flashlights. This raises concerns about the interests of low-income flashlight users, and it may also indicate the onset of a broader market spoiling effect for off-grid lighting products based on LED technology (Mills and Jacobson, 2008; Lighting Africa, 2007). The quality of low-cost LED flashlights can contribute to market spoiling because these products appear to represent the first contact that most Kenyans have with LED technology. In this report, our team uses interviews with 46 end users of flashlights to collect information about their experiences, perceptions, and preferences. We focus especially on highlighting common complaints from respondents about the flashlights that they have used, as well as on noting the features that they indicated were important when evaluating the quality of a flashlight. In previous laboratory tests, researchers

    Advanced Rapid Imaging and Analysis (ARIA) Center for Natural Hazards aims to bring state-of-the-art geodetic imaging capabilities to an operational level in support of local, national, and international hazard response communities. ARIA project's first foray into operational generation of InSAR products was with Calimap Project, in collaboration with ASI-CIDOT, using X-band data from the Cosmo-SkyMed constellation. Over the last year, ARIA's processing infrastructure has been significantly upgraded to exploit the free stream of high quality C-band SAR data from ESA's Sentinel-1 mission and related algorithmic improvements to the ISCE software. ARIA's data system can now operationally generate geocoded unwrapped phase and coherence products in GIS-friendly formats from Sentinel-1 TOPS mode data in an automated fashion, and this capability is currently being exercised various study sites across the United States including Hawaii, Central California, Iceland and South America. The ARIA team, building on the experience gained from handling X-band data and C-band data, has also built an automated machine learning-based classifier to label the auto-generated interferograms based on phase unwrapping quality. These high quality "time-series ready" InSAR products generated using state-of-the-art processing algorithms can be accessed by end users using two different mechanisms - 1) a Faceted-search interface that includes browse imagery for quick visualization and 2) an ElasticSearch-based API to enable bulk automated download, post-processing and time-series analysis. In this talk, we will present InSAR results from various global events that ARIA system has responded to. We will also discuss the set of geospatial big data tools including GIS libraries and API tools, that end users will need to familiarize themselves with in order to maximize the utilization of continuous stream of InSAR products from the Sentinel-1 and NISAR missions that the ARIA project will generate.

    Full Text Available Complex information systems like the ERP integrate the data of all business areas within the organization. The implementation of ERP is a difficult process as it involves different types of end users. Based on literature, we proposed a conceptual framework and examined it to find the effect of some of the individual, organizational, and technological factors on the usage of ERP and its impact on the end user. The results of the analysis suggest that computer self-efficacy, organizational support, training, and compatibility have a positive influence on ERP usage which in turn has significant influence on panoptic empowerment and individual performance.

    This paper presents results of modelling cost optimised electricity generation systems for renewable energy shares varying from 0 % to 100 % on an hourly timescale. The model takes into account generation from solar photovoltaics (PV), wind, hydro, biogas and natural gas fuelled power plants. Storage is incorporated as short-term storage in batteries and biogas bladders and long-term storage via renewable power methane (RPM) and biomethane. Gridparity enabled PV-battery systems are taken into account to model electricity end-user behaviour. We use localised hourly solar insolation, wind and hydro power output, and electricity demand data. Results include optimum component sizing as well as levelised cost of electricity (LCOE). Impacts of changing storage technology prices are investigated.

    Full Text Available The global Business Intelligence (BI market grew by 10% in 2013 according to the Gartner Report. Today organizations require better use of data and analytics to support their business decisions. Internet power and business trend changes have provided a broad term for data analytics – Big Data. To be able to handle it and leverage a value of having access to Big Data, organizations have no other choice than to get proper systems implemented and working. However traditional methods are not efficient for changing business needs. The long time between project start and go-live causes a gap between initial solution blueprint and actual user requirements in the end of the project. This article presents the latest market trends in BI systems implementation by comparing Agile with traditional methods. It presents a case study provided in a large telecommunications company (20K employees and the results of a pilot research provided in the three large companies: telecommunications, digital, and insurance. Both studies prove that Agile methods might be more effective in BI projects from an end-user perspective and give first results and added value in a much shorter time compared to a traditional approach.

    The experiences gathered during the past 30 years support the operational use of irrigation scheduling based on frequent multi-spectral image data. Currently, the operational use of dense time series of multispectral imagery at high spatial resolution makes monitoring of crop biophysical parameters feasible, capturing crop water use across the growing season, with suitable temporal and spatial resolutions. These achievements, and the availability of accurate forecasting of meteorological data, allow for precise predictions of crop water requirements with unprecedented spatial resolution. This information is greatly appreciated by the end users, i.e., professional farmers or decision-makers, and can be provided in an easy-to-use manner and in near-real-time by using the improvements achieved in web-GIS methodologies (Geographic Information Systems based on web technologies). This paper reviews the most operational and explored methods based on optical remote sensing for the assessment of crop water requirements, identifying strengths and weaknesses and proposing alternatives to advance towards full operational application of this methodology. In addition, we provide a general overview of the tools, which facilitates co-creation and collaboration with stakeholders, paying special attention to these approaches based on web-GIS tools.

    2013-05-01

    The usability of a rapid point-of-care ABO-Rh blood typing kit was determined by comparing the performance of individuals with extensive medical training/experience to those with a lesser extent. Subjects were asked to use the blood typing kit with their own blood. These outcomes were compared to that listed in the subject's medical record, stamped on their dog tag, and the result interpreted by a laboratorian. For all participants, there was ∼80% consistency between the result interpreted by the subject and that stated in their medical record. The participant's level of formal education (P ≤ 0.05) affected the accuracy of the blood typing kit. When comparing the subject's outcome to that stated in their medical record, the performance of individuals in the Medical Corps was approximately 10% and 25% higher (P < 0.05) than that observed with Hospital Corpsman or Medical Service Corps members, respectively. To remove bias that can occur when interpreting the blood type of oneself, the subjects also interpreted the result from cards prepared by the investigator. Taken together, a discrepancy between the potential diagnostic accuracy of the kit and that observed with potential end users was identified.

  1. Closing the Gap between Methodologists and End-Users: R as a Computational Back-End

    Directory of Open Access Journals (Sweden)

    Byron C. Wallace

    2012-06-01

    Full Text Available The R environment provides a natural platform for developing new statistical methods due to the mathematical expressiveness of the language, the large number of existing libraries, and the active developer community. One drawback to R, however, is the learning curve; programming is a deterrent to non-technical users, who typically prefer graphical user interfaces (GUIs to command line environments. Thus, while statisticians develop new methods in R, practitioners are often behind in terms of the statistical techniques they use as they rely on GUI applications. Meta-analysis is an instructive example; cutting-edge meta-analysis methods are often ignored by the overwhelming majority of practitioners, in part because they have no easy way of applying them. This paper proposes a strategy to close the gap between the statistical state-of-the-science and what is applied in practice. We present open-source meta-analysis software that uses R as the underlying statistical engine, and Python for the GUI. We present a framework that allows methodologists to implement new methods in R that are then automatically integrated into the GUI for use by end-users, so long as the programmer conforms to our interface. Such an approach allows an intuitive interface for non-technical users while leveraging the latest advanced statistical methods implemented by methodologists.

    The purpose of this study was to establish the level of ease of use and effectiveness of the Orchard Sport Injury Classification System (OSICS) 10.1 Plus for recording injuries and interventions. Three hundred and forty-two (males=148, females=192, no response=2; age=30.9±9.5y; experience=9.1±10.5y) athletic trainers (ATs) in the United States completed the survey. Participants were primarily employed in the secondary school (n=135) or collegiate setting (n=171). Participants entered system includes the OSICS 10.1 to catalog injuries and Current Procedural Terminology (CPT) codes to document interventions. Participants completed an 18-item end-user evaluation to assess the ease of use and effectiveness of the OSICS 10.1 Plus (5-point Likert scale). Participants indicated that the OSICS 10.1 Plus is overall easy to use (4.1±0.7pts), easy to enter an injury (4.1±0.8pts), and easy to enter the associated interventions (3.9±0.8pts). Respondents were neutral about whether the OSICS 10.1 Plus matched their current injury (3.5±1.0pts) or intervention (3.5±0.9pts) records. A majority of participants indicated that they could find the injury (281/342, 82.2%) and interventions (225/342, 65.8%) of interest. A majority of respondents (205/342, 60.0%) indicated they would consider using OSICS 10.1 Plus for injury surveillance in clinical practice. The OSICS 10.1 Plus could serve as an effective and useful mechanism for injury surveillance with minor modifications; however, we, as professionals in sports healthcare, need to improve regular medical documentation first so that we are better able to conduct injury surveillance among our patients.

  11. Energy efficiency business options for industrial end users in Latin American competitive energy markets: The case of Colombia

    Botero, Sergio

    2002-01-01

    Energy markets today in Latin America and worldwide are being restructured from monopolies, either state-owned or privately-owned, to be more openly competitive and incorporate more participation from the private sector. Thus, the schemes that were formerly developed to foster end use energy efficiency are no longer applicable because they were based on mandatory regulations made with political decisions, without sufficiently considering economic feasibility. A consensus exists that the only way energy efficiency could survive in this new paradigm is by being market oriented, giving better services, and additional options to users. However; there is very little information on what end users prefer, and which options would most satisfy customers. Using Colombia as a case study, this research determines and categorizes the energy efficiency business options for large energy end users that can freely participate in the competitive energy market. The energy efficiency market is understood as a market of services aiming to increase efficiency in energy use. These services can be grouped into seven business options. A survey, following the descriptive method, was sent to energy end users in order to determine their preferences for specific energy efficiency business options, as well as the decision-making criteria taken into account for such options. This data was categorized in ten industry groups. As a conclusion, energy efficiency providers should adapt not only to the economic activity or processes of each customer, but also to the potential business options. It was also found that not all industries consider performance contracting as their most preferred option, as a matter of fact, some industries show much higher preference for conventional business options. Among end users, the divergence in option preferences contrasted with the convergence in decision-making criteria. The decision-making criteria "cost-benefit ratio" overwhelmed all other criterion.

    Full Text Available Brain-computer interfaces (BCIs translate oscillatory electroencephalogram (EEG patterns into action. Different mental activities modulate spontaneous EEG rhythms in various ways. Non-stationarity and inherent variability of EEG signals, however, make reliable recognition of modulated EEG patterns challenging. Able-bodied individuals who use a BCI for the first time achieve - on average - binary classification performance of about 75%. Performance in users with central nervous system (CNS tissue damage is typically lower. User training generally enhances reliability of EEG pattern generation and thus also robustness of pattern recognition. In this study, we investigated the impact of mental tasks on binary classification performance in BCI users with central nervous system (CNS tissue damage such as persons with stroke or spinal cord injury (SCI. Motor imagery (MI, that is the kinesthetic imagination of movement (e.g. squeezing a rubber ball with the right hand, is the "gold standard" and mainly used to modulate EEG patterns. Based on our recent results in able-bodied users, we hypothesized that pair-wise combination of "brain-teaser" (e.g. mental subtraction and mental word association and "dynamic imagery" (e.g. hand and feet MI tasks significantly increases classification performance of induced EEG patterns in the selected end-user group. Within-day (How stable is the classification within a day? and between-day (How well does a model trained on day one perform on unseen data of day two? analysis of variability of mental task pair classification in nine individuals confirmed the hypothesis. We found that the use of the classical MI task pair hand vs. feed leads to significantly lower classification accuracy - in average up to 15% less - in most users with stroke or SCI. User-specific selection of task pairs was again essential to enhance performance. We expect that the gained evidence will significantly contribute to make imagery-based BCI

    In EU project CLIMRUN, there has been a continuous interaction with stakeholders and end-users to develop new and improved tools to extract useful and useable information tailored to the needs of specific sectors. In this work, we review the provision of climate information services required in the Mediterranean country of Greece where forest fires represent a major hazard. Intense terrain, sparsely vegetated with typical Mediterranean flora makes Greece a fire prone environment. That, in addition to the abandonment of rural lands and extreme weather conditions due to climate change the last few decades, constitutes an issue of an annual cycle of catastrophe from forest fires. An iterative and bottom-up (i.e. stakeholder led) approach for optimizing the two-way information transfer between climate experts and stakeholders has been adopted from the start of the project with a workshop in Athens helping to define the framework for the forest fires case study. The main objectives of this workshop were to better understand who the wildfires stakeholders are and what they need from climate services. After the first workshop three main categories of stakeholders were identified: short term fire planners, long term policy makers and education stakeholders. To address the needs of these stakeholders' categories the following actions were taken: 1. In collaboration with the forecasting team at the National Observatory of Athens, an application providing fire risk forecasts for the following 3 days (http://cirrus.meteo.noa.gr/forecast/bolam/index.htm) was developed, to address the needs of short term fire planners. 2. A web-based application providing long term fire risk and other fire related indices changes due to climate change (time horizon up to 2050 and up to 2100) was developed in collaboration with the Greek WWF office, to address the needs of long term fire policy makers (http://www.oikoskopio.gr/map/). 3. Finally, an educational tool was built in order to

    Full Text Available The purpose of this study is to present, introduce and explain the principles, concepts and techniques of mashups through an analysis of mashup tools from End-user Development (EuD software engineering perspectives, since it is a new programming paradigm. Problem statement: Although mashup tools supporting the creation of mashups rely heavily on data integration, they still require users to have reasonable programming skills, rather than simply enabling the integration of content in a template approach. Mashup tools also have their lifespan in a fast moving technology-driven world which requires meta-application handling. Some developers have discontinued their mashup tools but others are still available in the mashup space. It has been noted that there is a steady increase of new mashups on a daily basis with a concomitant increase of new Application Programming Interface (APIs to support meta-mashup application EuD. Approach: Both qualitative and quantitative research methods have been utilized. After introducing the basic principles, concepts and techniques of mashups, we develop and present a categorization of mashups and mashup tools and summarize the ten most popular currently used mashup tools against seven indictors from end-user software engineering perspectives ranging from programming skill requirement, prompt suggestion of features use, operability, ‘share-ability’ and reuse, service, type and target user, in order to evaluate how these mashup tools support end-user development. To perform the evaluation and produce the final results, the selected indicators’ features have been horizontally compared and comprehensively analyzed. Results: The philosophy of mashup is aimed at providing simple rapid program development by end-users with minimum programming skills. However, we observe that mashup tools typically follow four data processing styles: Webpage customization, wire paradigm, spreadsheet and programming by

    Full Text Available Both judgment and receptivity are important to optimal politics, and both are important to each other. In making this argument, I use an Arendtian conception of judgment and take mindfulness as an example of receptivity. I argue that receptivity offers a needed dimension to addressing the puzzles of what makes Arendtian judgment possible, and that judgment provides a necessary complement to receptivity for action in the world. Exploring this complementary relation between judgment and receptivity also reveals a surprising similarity between what each offers to the practice of politics, in particular to freedom and the possibility of transformation. At the same time, I argue, these important contributions to politics are best understood and realized if judgment and receptivity are thought of as distinct forms of relating to the world.

    Wholesale and retail competition in the deregulated electricity market in Ontario are reviewed. It is predicted that while wholesale prices are not likely to fall significantly in the short term, over time they will be driven down by competitive forces. With regard to retail consumers, the Ontario Market Design Committee model provides access to the wholesale spot price to all end users, thus retail consumers should get the full benefits of wholesale competition. In addition, retailers can also compete with the spot price, and with each other with fixed price offerings, with metering, and with energy management services. Green power marketing and environmental labeling should provide yet another avenue of competition. At the same time, end users should get reasonable protection from the excesses of over-aggressive marketers through consumer protection measures such as consumer information, limits on small customer contracts during the first year and prudential requirements designed to limit failure of retailers.

    I/O-intensive applications are becoming increasingly common on today's high-performance computing systems. While performance of compute-bound applications can be effectively guaranteed with techniques such as space sharing or QoS-aware process scheduling, it remains a challenge to meet QoS requirements for end users of I/O-intensive applications using shared storage systems because it is difficult to differentiate I/O services for different applications with individual quality requirements. Furthermore, it is difficult for end users to accurately specify performance goals to the storage system using I/O-related metrics such as request latency or throughput. As access patterns, request rates, and the system workload change in time, a fixed I/O performance goal, such as bounds on throughput or latency, can be expensive to achieve and may not lead to a meaningful performance guarantees such as bounded program execution time. We propose a scheme supporting end-users QoS goals, specified in terms of program execution time, in shared storage environments. We automatically translate the users performance goals into instantaneous I/O throughput bounds using a machine learning technique, and use dynamically determined service time windows to efficiently meet the throughput bounds. We have implemented this scheme in the PVFS2 parallel file system and have conducted an extensive evaluation. Our results show that this scheme can satisfy realistic end-user QoS requirements by making highly efficient use of the I/O resources. The scheme seeks to balance programs attainment of QoS requirements, and saves as much of the remaining I/O capacity as possible for best-effort programs.

    Full Text Available To attend Brazil‘s energy demands, considering the typical seasonality of Brazilian climates conditions, part of the energy available in the national electrical system has been generated from natural gas power plant (in the most recent years. This paper analyses a case of technology transfer with focus on end-users, observing theirs perception in relation to attributes of technological tool installed, a control and monitoring system. The case, developed in a thermoelectric power plant, has four organizations participants: the thermoelectric power plant that bought the technology, the company that will operate with the new technology, a research institution that helped out on the selection process and adjustments of technological tool to local necessities and the international supplier of the technology. This work used qualitative and quantitative methodology to arrive its purpose. Between the findings, there are some differences on perception of attributes for some users groups. Given the relevance of technological tool acquired, it‘s possible that communications actions and technical trainings would be necessaries to ensure that users know all the functionalities of new system, its advantages in relation to previous system and its compatibility with power plant‘s technical process. The technological dependency of foreign companies and necessities of adjustments to schedule of technological tool installation contributed for a partial transference of the technology observed, demanding future researches to check the overcoming of these limitations.

    Over the past two decades, urban lifestyles have changed phenomenally. One aspect of this change is the increasing use of household appliances, which, in turn, influences water and electricity consumption in urban households. It is therefore necessary to revisit water supply norms in view of these behavioural changes. Increasing use of water-related appliances by the surveyed households in Delhi, India has lowered their water consumption but increased their electricity consumption (10-16 kW h a month). Also, longer working hours away from homes have shifted water demand from homes to commercial establishments and institutions. The per-capita water requirement to meet the basic needs for health and hygiene is approximately 76-78 L a day, of which bathing claims the largest share (32%). Nearly 70% of electricity consumption of a household is spent in coping with deficiencies in water supply. Strategies adopted by end users to save water were negatively correlated with those to save electricity. Household incomes have no influence on water consumption except in the case of those living in slums, who are forced to curtail their use of water even at the cost of health and hygiene; for the rest, coping with poor water supply amounts to spending nearly 50% more on electricity, defeating the purpose of subsidised water supply.

    Household point-of-use (POU) water treatment technologies targeted at vulnerable populations are microbiologically effective and, in small trials, improve health. We do not understand the factors that influence preference for and adoption of these technologies by target end-users. We cycled 400 rural subsistence farm households in western Kenya through three randomly ordered two-month trials of three POU products: dilute hypochlorite solution, porous ceramic filtration, and a combined flocculant-disinfectant powdered mixture to compare relative end-user preferences and usage. Households reported higher usage of both dilute hypochlorite and filters than the flocculant-disinfectant. Averaged among all participating households, Escherichia coli reductions in treated water were generally higher among those that received dilute hypochlorite solution than among those receiving either of the other two products. Among those households that self-reported product usage, the E. coli reductions achieved by dilute hypochlorite and the flocculant-disinfectant are statistically equivalent to one another and higher than the reductions achieved by filters. At the same time, households ranked filters most frequently as their most preferred product.

    End-user development is a new trend to provide tailored services to dynamic environments such as hospitals. These services not only facilitate daily work for pharmacy personnel but also improve self-care in elder people that are still related to hospital, such as discharged patients. This paper presents an ambient intelligence (AmI) environment for End-user service provisioning in the pharmacy department of Gregorio Marañón Hospital in Madrid, composed of a drug traceability infrastructure (DP-TraIN) and a ubiquitous application for enabling the pharmacy staff to create and execute their own services for facilitating drug management and dispensing. The authors carried out a case study with various experiments where different roles from the pharmacy department of Gregorio Marañón Hospital were involved in activities such as drug identification, dispensing and medication administering. The authors analyzed the effort required to create services by pharmacy staff, the discharged patients' perception of the AmI environment and the quantifiable benefits in reducing patient waiting time for drug dispensing.

    Motor disability and/or ageing can prevent individuals from fully enjoying home facilities, thus worsening their quality of life. Advances in the field of accessible user interfaces for domotic appliances can represent a valuable way to improve the independence of these persons. An asynchronous P300-based Brain-Computer Interface (BCI) system was recently validated with the participation of healthy young volunteers for environmental control. In this study, the asynchronous P300-based BCI for the interaction with a virtual home environment was tested with the participation of potential end-users (clients of a Frisian home care organization) with limited autonomy due to ageing and/or motor disabilities. System testing revealed that the minimum number of stimulation sequences needed to achieve correct classification had a higher intra-subject variability in potential end-users with respect to what was previously observed in young controls. Here we show that the asynchronous modality performed significantly better as compared to the synchronous mode in continuously adapting its speed to the users' state. Furthermore, the asynchronous system modality confirmed its reliability in avoiding misclassifications and false positives, as previously shown in young healthy subjects. The asynchronous modality may contribute to filling the usability gap between BCI systems and traditional input devices, representing an important step towards their use in the activities of daily living.

    Background Increasingly, Web-based health applications are developed for the prevention and management of chronic diseases. However, their reach and utilization is often disappointing. Qualitative evaluations post-implementation can be used to inform the optimization process and ultimately enhance their adoption. In current practice, such evaluations are mainly performed with end-user surveys. However, a review approach by experts in a focus group may be easier to administer and might provide similar results. Objective The aim of this study was to assess whether industrial design engineers in a focus group would address the same issues as end users in a Web-based survey when evaluating a commercial Web-based health risk assessment (HRA) with tailored feedback. Methods Seven Dutch companies used the HRA as part of their corporate health management strategy. Employees using the HRA (N=2289) and 10 independent industrial designers were invited to participate in the study. The HRA consisted of four components: (1) an electronic health questionnaire, (2) biometric measurements, (3) laboratory evaluation, and (4) individually tailored feedback generated by decision support software. After participating in the HRA as end users, both end users and designers evaluated the program. End users completed an evaluation questionnaire that included a free-text field. Designers participated in a focus group discussion. Constructs from user satisfaction and technology acceptance theories were used to categorize and compare the remarks from both evaluations. Results We assessed and qualitatively analyzed 294 remarks of 189 end users and 337 remarks of 6 industrial designers, pertaining to 295 issues in total. Of those, 137 issues were addressed in the end-user survey and 148 issues in the designer focus group. Only 7.3% (10/137) of the issues addressed in the survey were also addressed in the focus group. End users made more remarks about the usefulness of the HRA and prior

    As new technologies emerge, and Web sites become increasingly sophisticated, ensuring they remain accessible to disabled and small-screen users is a major challenge. While guidelines and automated evaluation tools are useful for informing some aspects of Web site design, numerous studies have demonstrated that they provide no guarantee that the site is genuinely accessible. The only reliable way to evaluate the accessibility of a site is to study the intended users interacting with it. This chapter outlines the processes that can be used throughout the design life cycle to ensure Web accessibility, describing their strengths and weaknesses, and discussing the practical and ethical considerations that they entail. The chapter also considers an important emerging trend in user evaluations: combining data from studies of “standard” Web use with data describing existing accessibility issues, to drive accessibility solutions forward.

    Geologists are tiny creatures living on the 2-and-a-bit-D surface of a sphere who observe essentially 1D vanishingly small portions (boreholes, roadcuts, stream and beach sections) of complex, 4D tectonic-scale structures. Field observations of fault zones are essential to understand the processes of fault growth and to make predictions of fault zone mechanical and hydraulic properties at depth. Here, we argue that a failure of geologists to communicate their knowledge effectively to other scientists/engineers can lead to unrealistic assumptions being made about fault properties, and may result in poor economic performance and a lack of robustness in industrial safety cases. Fault zones are composed of many heterogeneously distributed deformation-related elements. Low permeability features include regions of intense grain-size reduction, pressure solution, cementation and shale smears. Other elements are likely to have enhanced permeability through fractures and breccias. Slip surfaces can have either enhanced or reduced permeability depending on whether they are open or closed, and the local stress state. The highly variable nature of 1) the architecture of faults and 2) the properties of deformation-related elements demonstrates that there are many factors controlling the evolution of fault zone internal structures (fault architecture). The aim of many field studies of faults is to provide data to constrain predictions at depth. For these data to be useful, pooling of data from multiple sites is usually necessary. This effort is frequently hampered by variability in the usage of fault terminologies. In addition, these terms are often used in ways as to make it easy for 'end-users' such as petroleum reservoir engineers, mining geologists, and seismologists to mis-interpret or over-simplify the implications of field studies. Field geologists are comfortable knowing that if you walk along strike or up dip of a fault zone you will find variations in fault rock type

    Introduction In planning for the introduction of vaginal microbicides and other new antiretroviral (ARV)-based prevention products for women, an in-depth understanding of potential end-users will be critically important to inform strategies to optimize uptake and long-term adherence. User-centred private sector companies have contributed to the successful launch of many different types of products, employing methods drawn from behavioural and social sciences to shape product designs, marketing messages and communication channels. Examples of how the private sector has adapted and applied these techniques to make decisions around product messaging and targeting may be instructive for adaptation to microbicide introduction. Discussion In preparing to introduce a product, user-centred private sector companies employ diverse methods to understand the target population and their lifestyles, values and motivations. ReD Associates’ observational research on user behaviours in the packaged food and diabetes fields illustrates how ‘tag along’ or ‘shadowing’ techniques can identify sources of non-adherence. Another open-ended method is self-documentation, and IDEO's mammography research utilized this to uncover user motivations that extended beyond health. Mapping the user journey is a quantitative approach for outlining critical decision-making stages, and Monitor Inclusive Markets applied this framework to identify toilet design opportunities for the rural poor. Through an iterative process, these various techniques can generate hypotheses on user drop-off points, quantify where drop-off is highest and prioritize areas of further research to uncover usage barriers. Although research constraints exist, these types of user-centred techniques have helped create effective messaging, product positioning and packaging of health products as well as family planning information. These methods can be applied to microbicide acceptability testing outside of clinical trials

    Community health workers are reemerging as an essential component of health systems in low-income countries. However, there are concerns that unless they are adequately supported, their motivation and performance will be suboptimal. mHealth presents an opportunity to improve support for community health workers; however, most interventions to date have been designed through a top-down approach, rarely involve the end user, and have not focused on motivation. To use formative research to explore the views of community health workers in Uganda and Mozambique on the potential role of mHealth in their work delivering integrated community case management of children. We conducted 24 in-depth interviews and 5 focus group discussions with community health workers in Uganda and Mozambique. Data were collected on: current phone use, preferred phone and charger characteristics, and perceptions of a range of potential mHealth interventions. Interviews were conducted in the local language, were audio recorded and converted into expanded notes. Interviews were coded for key thematic areas using both deductive and inductive codes. Deductive codes included mHealth's potential impact on motivation and performance. The most salient roles of mHealth in improving performance and motivation were reducing the need for travel, improving efficiency and planning, receiving feedback and information, and improving communication with supervisors and other community health workers. This was mostly through improved voice and short message service (SMS) text communication. Specific components of mHealth interventions that participants felt could improve motivation included increasing their visibility and credibility through branding of phones; providing an SMS response to data submission; and sending SMS messages about the importance of their work and achievements, rather than just reminders or technical messages. Participants identified feasibility issues related to the language of SMS

    Full Text Available Introduction: In planning for the introduction of vaginal microbicides and other new antiretroviral (ARV-based prevention products for women, an in-depth understanding of potential end-users will be critically important to inform strategies to optimize uptake and long-term adherence. User-centred private sector companies have contributed to the successful launch of many different types of products, employing methods drawn from behavioural and social sciences to shape product designs, marketing messages and communication channels. Examples of how the private sector has adapted and applied these techniques to make decisions around product messaging and targeting may be instructive for adaptation to microbicide introduction. Discussion: In preparing to introduce a product, user-centred private sector companies employ diverse methods to understand the target population and their lifestyles, values and motivations. ReD Associates’ observational research on user behaviours in the packaged food and diabetes fields illustrates how ‘tag along’ or ‘shadowing’ techniques can identify sources of non-adherence. Another open-ended method is self-documentation, and IDEO's mammography research utilized this to uncover user motivations that extended beyond health. Mapping the user journey is a quantitative approach for outlining critical decision-making stages, and Monitor Inclusive Markets applied this framework to identify toilet design opportunities for the rural poor. Through an iterative process, these various techniques can generate hypotheses on user drop-off points, quantify where drop-off is highest and prioritize areas of further research to uncover usage barriers. Although research constraints exist, these types of user-centred techniques have helped create effective messaging, product positioning and packaging of health products as well as family planning information. These methods can be applied to microbicide acceptability testing outside

    The fact that patient satisfaction with primary care clinical practices and physician-patient communications has decreased gradually has brought a new opportunity to the online channel as a supplementary service to provide additional information. In this study, our objectives were to examine the process of cognitive knowledge expectation-confirmation from eHealth users and to recommend the attributes of a "knowledge-intensive website.". Knowledge expectation can be defined as users' existing attitudes or beliefs regarding expected levels of knowledge they may gain by accessing the website. Knowledge confirmation is the extent to which user's knowledge expectation of information systems use is realized during actual use. In our hypothesized research model, perceived information quality, presentation and attractiveness as well as knowledge expectation influence knowledge confirmation, which in turn influences perceived usefulness and end user satisfaction, which feeds back to knowledge expectation. An empirical study was conducted at the National Cancer Center (NCC), Republic of Korea (South Korea), by evaluating its official website. A user survey was administered containing items to measure subjectively perceived website quality and expectation-confirmation attributes. A study sample of 198 usable responses was used for further analysis. We used the structural equation model to test the proposed research model. Knowledge expectation exhibited a positive effect on knowledge confirmation (beta = .27, P knowledge confirmation were also positive and significant (beta = .24, P knowledge confirmation on perceived usefulness was also positively significant (beta = .64, P Knowledge expectation together with knowledge confirmation and perceived usefulness also significantly affected end user satisfaction (beta = .22 P knowledge-intensive website attributes, (2) enhanced the theoretical foundation of eHealth from the information systems (IS) perspective by adopting the

    Full Text Available INTRODUCTION: Network meta-analyses (NMAs are complex methodological approaches that may be challenging for non-technical end-users, such as policymakers and clinicians, to understand. Consideration should be given to identifying optimal approaches to presenting NMAs that help clarify analyses. It is unclear what guidance researchers currently have on how to present and tailor NMAs to different end-users. METHODS: A systematic review of NMA guidelines was conducted to identify guidance on how to present NMAs. Electronic databases and supplementary sources were searched for NMA guidelines. Presentation format details related to sample formats, target audiences, data sources, analysis methods and results were extracted and frequencies tabulated. Guideline quality was assessed following criteria developed for clinical practice guidelines. RESULTS: Seven guidelines were included. Current guidelines focus on how to conduct NMAs but provide limited guidance to researchers on how to best present analyses to different end-users. None of the guidelines provided reporting templates. Few guidelines provided advice on tailoring presentations to different end-users, such as policymakers. Available guidance on presentation formats focused on evidence networks, characteristics of individual trials, comparisons between direct and indirect estimates and assumptions of heterogeneity and/or inconsistency. Some guidelines also provided examples of figures and tables that could be used to present information. CONCLUSIONS: Limited guidance exists for researchers on how best to present NMAs in an accessible format, especially for non-technical end-users such as policymakers and clinicians. NMA guidelines may require further integration with end-users' needs, when NMAs are used to support healthcare policy and practice decisions. Developing presentation formats that enhance understanding and accessibility of NMAs could also enhance the transparency and legitimacy of

    Automated high-content screening and analysis (HCS/HCA) technology solutions have become indispensable in expediting the pace of drug discovery. Because of the complexity involved in designing, building, and validating HCS/HCA platforms, it is important to design, build, and validate a HCS/HCA platform before it is actually needed. Managed properly, collaboration between technology providers and end users in research is essential in accelerating development of the hardware and software of new HCS/HCA platforms before they become commercially available. Such a collaboration results in the cost effective creation of new technologies that meet specific and customized industrial requirements. This review outlines the history of, and considerations relevant to, the development of the Cytometrix Profiling System by Cytokinetics, Inc. and the "Complete Imaging Solution" for high-content screening, developed by Molecular Devices Corporation (MDC) (now MDS Analytical Technologies), from original conception and testing of various components, to multiple development cycles from 1998 to the present, and finally to market consolidation.

  20. The Law of the Tendency of the Rate of Profit to Fall and the End User Communication Technology

    Peter Sekloča

    2015-03-01

    Full Text Available The author critically analyses the contemporary debate about the law of the tendential fall in the rate of profit in which Marx summed up the central contradiction of the capitalist mode of production. The results of the analysis are then applied on the business strategies of the informational capitalism in the segment of end users of the informational and communicational technology. Unpaid labor of users for digital media platform owners as well as hardware and software purchase both resemble peculiar counteracting tendencies for the “law”. The analysis indicates that the immaterial labor and outsourcing of equipment may truly increase the profit rate in a way that was rather inconceivable in Marx's day, but this still does not undermine the “law’s” validity. Counteracting tendencies have their own limits and that is also why the capital does not allow them to reach their end and restore conditions for a “new” central contradiction conceptualized by Italian autonomists.

    Full Text Available Nowadays, location-enabled mobile phones are becoming more and more widespread. Various players in the mobile business forecast that, in the future, a significant part of total wireless revenue will come from Location-Based Services (LBS. An LBS system extracts information about the user’s geographical location and provides services based on the positioning information. A successful LBS service should create value for the end-user, by satisfying some of the users’ needs or wants, and at the same time preserving the key factors of the mobile wireless device, such as low costs, low battery consumption, and small size. From many users’ perspectives, location services and mobile location capabilities are still rather poorly known and poorly understood. The aim of this research is to investigate users’ views on the LBS, their requirements in terms of mobile device characteristics, their concerns in terms of privacy and usability, and their opinion on LBS applications that might increase the social wellbeing in the future wireless world. Our research is based on two surveys performed among 105 students (average student age: 24 years from two European technical universities. The survey questions were intended to solicit the youngsters’ views on present and future technological trends and on their perceived needs and wishes regarding Location-Based Services, with the aim of obtaining a better understanding of designer constraints when building a location receiver and generating new ideas related to potential future killer LBS applications.

    Water availability pressures, competing end-uses and sewers at capacity are all drivers for change in urban water management. Rainwater harvesting (RWH) and greywater reuse (GWR) systems constitute alternatives to reduce drinking water usage and in the case of RWH, reduce roof runoff entering sewers. Despite the increasing popularity of installations in commercial buildings, RWH and GWR technologies at a household scale have proved less popular, across a range of global contexts. For systems designed from the top-down, this is often due to the lack of a favourable cost-benefit (where subsidies are unavailable), though few studies have focused on performing full capital and operational financial assessments, particularly in high water consumption households. Using a bottom-up design approach, based on a questionnaire survey with 35 households in a residential complex in Bucaramanga, Colombia, this article considers the initial financial feasibility of three RWH and GWR system configurations proposed for high water using households (equivalent to >203 L per capita per day). A full capital and operational financial assessment was performed at a more detailed level for the most viable design using historic rainfall data. For the selected configuration ('Alt 2'), the estimated potable water saving was 44% (equivalent to 131 m(3)/year) with a rate of return on investment of 6.5% and an estimated payback period of 23 years. As an initial end-user-driven design exercise, these results are promising and constitute a starting point for facilitating such approaches to urban water management at the household scale.

    : The perceived benefits of rapid response teams (RRTs) influence whether RRTs are used and sustained. Perceived benefits are particularly important to sustaining RRTs when limited RRT data are shared with organizational members. Nurse leaders' perceptions of the benefits of RRTs likely influence their support, which is crucial for sustained RRT use. The perceptions of RRT members and end users similarly will affect use. But little is known regarding the perceptions of nurse leaders, RRT members, and RRT users in this regard.This study sought to explore and compare the perceptions of nurse leaders, RRT members, and RRT users regarding the benefits of RRTs.A qualitative, multiple-case study design was used. Semistructured interviews were conducted with nurse leaders, RRT members, and RRT users at four community hospitals, as part of a larger mixed-methods study examining RRT sustainability. Purposive and snowball sampling were used. Recruitment strategies included e-mail and listserv announcements, on-site presentations, direct personal contact, and a study flyer.All participants reported perceiving various ways that RRTs benefit the organization, staff members, and patients. Variations in the benefits perceived were observed between the three participant groups. Nurse leaders' perceptions tended to focus on macro-level benefits. RRT members emphasized the teaching and learning opportunities that RRTs offer. RRT users focused on the psychological support that RRTs can provide.Both similarities and differences were found between nurse leaders, RRT members, and RRT users regarding their perceptions of RRT benefits. Differences may be indicative of organizations' information-sharing processes; of variation in the priorities of nurse leaders, RRT members, and RRT users; and of the challenges nurses face daily in their work environments. Future research should investigate whether the perceived benefits of RRTs are borne out in actuality, as well as the relationships

    The aim of the present work was to examine adult smokers' awareness of and receptivity to an electronic nicotine delivery system (ENDS) television advert, and whether viewing the advert influenced urge to smoke and intention to try ENDS. A television advert for ENDS brand blu eCigs was shown to an online convenience sample of 519 Florida adult smokers. We measured current smokers' awareness of and receptivity to the advert, and whether seeing the advert influenced their thoughts about smoking or quitting, urge to smoke and intention to try ENDS. Results were stratified by prior ENDS use. Approximately 62.3% of current smokers were aware of the advert. Smokers found the advert informative (73.8%), attention grabbing (67.5%) and innovative (64.5%), with prior ENDS users rating the advert more favourably than non-users. Seeing the advert elicited an urge to smoke (mean 42.1, SD=1.9) and thoughts about smoking cigarettes (75.8%) as well as quitting (74.6%). Prior END users were significantly more likely than non-users to report thinking about smoking cigarettes after seeing the advert (Padvertising and examine how exposure to ENDS adverts influences smokers' use of ENDS, dual use with cigarettes and cessation behaviour.

    Full Text Available BACKGROUND: Decision-support tools (DST are typically developed by computer engineers for use by clinicians. Prototype testing DSTs may be performed relatively easily by one or two clinical experts. The costly alternative is to test each prototype on a larger number of diverse clinicians, based on the untested assumption that these evaluations would more accurately reflect those of actual end users.HYPOTHESIS: We hypothesized substantial or better agreement (as defined by a kappa statistic greater than 0.6 between the evaluations of a case based reasoning (CBR DST predicting ED admission for bronchiolitis performed by the clinically diverse end users, to those of two clinical experts who evaluated the same DST output.METHODS: Three outputs from a previously described DST were evaluated by the emergency physicians (EP who originally saw the patients and by two pediatric EPs with an interest in bronchiolitis. The DST outputs were as follows: predicted disposition, an example of another previously seen patient to explain the prediction, and explanatory dialog. Each was rated using the scale Definitely Not, No, Maybe, Yes, and Absolutely. This was converted to a Likert scale for analysis. Agreement was measured using the kappa statistic.RESULTS: Agreement with the DST predicted disposition was moderate between end users and the expert reviewers, but was only fair or poor for value of the explanatory case and dialog.CONCLUSION: Agreement between expert evaluators and end users on the value of a CBR DST predicted dispositions was moderate. For the more subjective explicative components, agreement was fair, poor, or worse.

    Tick bites and tick-borne infections are an increasingly large problem. There is a wide range of precautions that citizens can take, but compliance is low. Mobile technology can offer a solution here, as they allow citizens to access health information in context. In this article, we discuss the development of requirements for a mobile app to support citizens in dealing with ticks and tick bites. First, we identified organizational stakeholders based on relevant protocols, and primary end-users via a systematic risk determination procedure. Then, we profiled end-users based on 25 in-depth interviews. We consulted organizational stakeholders via a focus group. The mobile app should primarily motivate citizens to check themselves for tick bites after visiting a risk area. The app should also include a tick radar, alerts to remind people to check for tick bites, and the possibility to document tick bites. Our experiences underline the necessity of thoroughly investigating the designated end-users and their context of use in order to tailor preventive health advice, and we demonstrate how this can be done. Finally, this case shows the need to create persuasive health technology in order to maximize citizen compliance.

    Serve and serve-reception performance have predicted success in volleyball. Given the impact of serve-reception on the game, we aimed at understanding what it is in the serve and receiver's actions that determines the selection of the type of pass used in serve-reception and its efficacy. Four high-level volleyball players received jump-float serves from four servers in two reception zones—zone 1 and 5. The ball and the receiver's head were tracked with two video cameras, allowing 3D world-coordinates reconstruction. Logistic-regression models were used to predict the type of pass used (overhand or underhand) and serve-reception efficacy (error, out, or effective) from variables related with the serve kinematics and related with the receiver's on-court positioning and movement. Receivers' initial position was different when in zone 1 and 5. This influenced the serve-related variables as well as the type of pass used. Strong predictors of using an underhand rather than overhand pass were higher ball contact of the server, reception in zone 1, receiver's initial position more to the back of the court and backward receiver movement. Receiver's larger longitudinal displacements and an initial position more to the back of the court had a strong relationship with the decreasing of the serve-reception efficacy. Receivers' positioning and movement were the factors with the largest impact on the type of pass used and the efficacy of the reception. Reception zone affected the variance in the ball's kinematics (with the exception of the ball's lateral displacement), as well as in the receivers' positioning (distances from the net and from the target). Also the reception zone was associated with the type of pass used by the receiver but not with reception efficacy. Given volleyball's rotation rule, the receiver needs to master receiving in the different reception zones; he/she needs to adapt to the diverse constraints of each zone to maintain performance efficacy. Thus

    Full Text Available In this study, we collected and analyzed information on the importance of drug packaging quality to end users and pharmaceutical industry, as an indicator of the process of traceability and originality of drugs. Two surveys were conducted: one among the end users of drugs (252 patients and the other among professionals working in seven pharmaceutical companies in Serbia. For most end users (82.5% quality on the packaging of drugs was important, but only 41.8% of them thought that the appearance of the packaging could be an indicator of genuinity of drugs. The existence of the control marks (KM on drug packaging was not of great importance, since most of them (86.9% know, its function, but majority (60.2% would nevertheless decide to buy the drug without KM. Regarding the experts from the pharmaceutical industry, more then two-thirds of them (68.4% believed that the existence of KM did not contribute to efficient operations. Although a great number of pharmaceutical industry professionals (84.2% answered that the introduction of GS1 DataMatrix system would allow for complete traceability of the drug from the manufacturer to the end user, only 22.2% of them introduced this system to their products. This study also showed that domestic producers did not have a great interest for additional protection (special inks, holograms, special graphics, smart multicolor design, watermark, chemically labeled paper and cardboard etc.. on their products, given that only 15.8 % of them had some kind of additional protection against counterfeiting. Monitoring drug traceability from a manufacturer to end user is achieved by many complex activities regulated by law. A high percentage of responders said they were satisfied with the functionality of traceability systems used in their companies. As a way to increase the quality of drug packaging and business performance most responders saw in the continuous improvement of the system of traceability within the company

End-users were involved in all stages of the project, both as authors and as members of an advisory group. In addition, several events were held with groups of relevant end-users during the project. End-user input (i) guided the direction of the research, (ii) contributed to a typology of interventions and outcomes, (iii) contributed to the direction of data analysis and (iv) contributed to the robustness of the syntheses by demonstrating the alignment of interim findings with lived experiences. Challenges included (i) managing expectations, (ii) managing the intensity of emotion, (iii) ensuring that involvement was fruitful for all not just the researcher, (iv) our capacity to communicate and manage the process and (v) engendering a sense of involvement amongst end-users. End-user involvement was an important aspect of this project. To minimize challenges in future projects, a recognition by the project management team and the funding provider that end-user involvement even in evidence synthesis projects is resource intensive is essential to allow appropriate allocation of time and resources for meaningful engagement. © 2015 The Authors.

    Accelerated market penetration of plug-in electric vehicles and deployment of grid-connected energy storage are restricted by the high cost of lithium-ion batteries. Research, development, and manufacturing are underway to lower material costs, enhance process efficiencies, and increase production volumes. A fraction of the battery cost may be recovered after vehicular service by reusing the battery where it may have sufficient performance for other energy-storage applications. By extracting post-vehicle additional services and revenue from the battery, the total lifetime value of the battery is increased. The overall cost of energy-storage solutions for both primary (automotive) and secondary (grid) customer could be decreased. This techno-economic analysis of battery second use considers effects of battery degradation in both automotive and grid service, repurposing costs, balance-of-system costs, the value of aggregated energy-storage to commercial and industrial end users, and competitive technology. Batteries from plug-in electric vehicles can economically be used to serve the power quality and reliability needs of commercial and industrial end users. However, the value to the automotive battery owner is small (e.g., $20-$100/kWh) as declining future battery costs and other factors strongly affect salvage value. Repurposed automotive battery prices may range from $38/kWh to $132/kWh.

    Today, technological implants are being developed to increase innate human capacities, such as memory or calculation speed, and to endow us with new ones, such as the remote control of machines. This study's aim was two-fold: first, to introduce a Cognitive-Affective-Normative (CAN) model of technology acceptance to explain the intention to use this technology in the field of consumer behavior; and second, to analyze the differences in the intention to use it based on whether the intended implant recipient is oneself or one's child (i.e., the moderating effect of the end user). A multi-group analysis was performed to compare the results between the two groups: implant "for me" (Group 1) and implant "for my child" (Group 2). The model largely explains the intention to use the insideable technology for the specified groups [variance explained (R (2)) of over 0.70 in both cases]. The most important variables were found to be "positive emotions" and (positive) "subjective norm." This underscores the need to broaden the range of factors considered to be decisive in technology acceptance to include variables related to consumers' emotions. Moreover, statistically significant differences were found between the "for me" and "for my child" models for "perceived ease of use (PEU)" and "subjective norm." These findings confirm the moderating effect of the end user on new insideable technology acceptance.

    Full Text Available Today, technological implants are being developed to increase innate human capacities, such as memory or calculation speed, and to endow us with new ones, such as the remote control of machines. This study’s aim was twofold: first, to introduce a Cognitive-Affective-Normative model of technology acceptance to explain the intention to use this technology in the field of consumer behavior; and second, to analyze the differences in the intention to use it based on whether the intended implant recipient is oneself or one’s child (i.e., the moderating effect of the end user. A multi-group analysis was performed to compare the results between the two groups: implant for me (Group 1 and implant for my child (Group 2. The model largely explains the intention to use the insideable technology for the specified groups (variance explained (R2 of over 0.70 in both cases. The most important variables were found to be positive emotions and (positive subjective norm. This underscores the need to broaden the range of factors considered to be decisive in technology acceptance to include variables related to consumers’ emotions. Moreover, statistically significant differences were found between the for me and for my child models for perceived ease of use and subjective norm. These findings confirm the moderating effect of the end user on new insideable technology acceptance.

  18. Price-elastic demand in deregulated electricity markets

    The degree to which any deregulated market functions efficiently often depends on the ability of market agents to respond quickly to fluctuating conditions. Many restructured electricity markets, however, experience high prices caused by supply shortages and little demand-side response. We examine the implications for market operations when a risk-averse retailer's end-use consumers are allowed to perceive real-time variations in the electricity spot price. Using a market-equilibrium model, we find that price elasticity both increases the retailers revenue risk exposure and decreases the spot price. Since the latter induces the retailer to reduce forward electricity purchases, while the former has the opposite effect, the overall impact of price responsive demand on the relative magnitudes of its risk exposure and end-user price elasticity. Nevertheless, price elasticity decreases cumulative electricity consumption. By extending the analysis to allow for early settlement of demand, we find that forward stage end-user price responsiveness decreases the electricity forward price relative to the case with price-elastic demand only in real time. Moreover, we find that only if forward stage end-user demand is price elastic will the equilibrium electricity forward price be reduced.

    Full Text Available This recent addition to the excellent Blackwell Companions series looks at the various forms of classical reception currently being researched as well as those deemed to have future importance. The diversity and volume of the themes and approaches contained in this book are truly impressive. As Hardwick and Stray state in their introduction, this collection “has been constructed on the basis that the activators of reception are many and varied and that we all gain from encountering examples from outside our own immediate areas of knowledge” (p. 4. Throughout the book they stay true to this motto and traditional approaches to classical reception are not given prominence over more recent (sometimes contentious approaches such as film studies, cultural politics and photography. The same goes for the various cultures involved and there is even a chapter on Greek drama in South Africa.

    Identifying the socioeconomic and cultural profile of users/readers of educational pamphlets, characterizing the context of the reading material and people involved; describing the user/reader evaluation on language and style used, as well as content range or limitations, and its characterization as an educational material in assisting users for meeting homecare demands. A reception, cross-sectional, qualitative study. 27 respondents who had received five educational pamphlets were interviewed on Oncology signs and symptoms during primary care consultations. Study participants were adults, with average schooling of more than 10 years and low income. Pamphlets were assessed as appropriate for consistent language, quantity and quality of content, and especially in relation to the capacity of helping in the homecare decision making process. The importance of receiving pamphlets at the initial stage of the disease was verified. Users acceptance was positive and the study revealed aspects that should be reinforced in the creation of educational pamphlets.

  4. WOD - Weather On Demand forecasting system

    2017-04-01

    The backbone of the Belgingur forecasting system (called WOD - Weather On Demand) is the WRF-Chem atmospheric model, with a number of in-house customisations. Initial and boundary data are taken from the Global Forecasting System, operated by the National Oceanic and Atmospheric Administration (NOAA). Operational forecasts use cycling of a number of parameters, mainly deep soil and surface fields. This is done to minimise spin-up effects and to ensure proper book-keeping of hydrological fields such as snow accumulation and runoff, as well as the constituents of various chemical parameters. The WOD system can be used to create conventional short- to medium-range weather forecasts for any location on the globe. The WOD system can also be used for air quality purposes (e.g. dispersion forecasts from volcanic eruptions) and as a tool to provide input to other modelling systems, such as hydrological models. A wide variety of post-processing options are also available, making WOD an ideal tool for creating highly customised output that can be tailored to the specific needs of individual end-users. The most recent addition to the WOD system is an integrated verification system where forecasts can be compared to surface observations from chosen locations. Forecast visualisation, such as weather charts, meteograms, weather icons and tables, is done via number of web components that can be configured to serve the varying needs of different end-users. The WOD system itself can be installed in an automatic way on hardware running a range of Linux based OS. System upgrades can also be done in semi-automatic fashion, i.e. upgrades and/or bug-fixes can be pushed to the end-user hardware without system downtime. Importantly, the WOD system requires only rudimentary knowledge of the WRF modelling, and the Linux operating systems on behalf of the end-user, making it an ideal NWP tool in locations with limited IT infrastructure.

  5. Sexual conflict over floral receptivity.

    2006-12-01

    In flowering plants, the onset and duration of female receptivity vary among species. In several species the receptive structures wilt upon pollination. Here we explore the hypothesis that postpollination wilting may be influenced by pollen and serve as a general means to secure paternity of the pollen donor at the expense of female fitness. Taking a game-theoretical approach, we examine the potential for the evolution of a pollen-borne wilting substance, and for the coevolution of a defense strategy by the recipient plant. The model without defense predicts an evolutionarily stable strategy (ESS) for the production of wilting substance. The ESS value is highest when pollinator visiting rates are intermediate and when the probability that pollen from several donors arrives at the same time is low. This finding has general implications in that it shows that male traits to secure paternity also can evolve in species, such as plants, where mating is not strictly sequential. We further model coevolution of the wilting substance with the timing of stigma receptivity. We assume that pollen-receiving plants can reduce the costs induced by toxic pollen by delaying the onset of stigmatic receptivity. The model predicts a joint ESS, but no female counter-adaptation when the wilting substance is highly toxic. This indicates that toxicity affects the probability that a male manipulative trait stays beneficial (i.e., not countered by female defense) over evolutionary time. We discuss parallels to male induced changes in female receptivity known to occur in animals and the role of harm for the evolution of male manipulative adaptations.

    A plethora of 3D and microfluidics-based culture models have been demonstrated in the recent years with the ultimate aim to facilitate predictive in vitro models for pharmaceutical development. This article summarizes to date the progress in the microfluidics-based tissue culture models, including organ-on-a-chip and vasculature-on-a-chip. Specific focus is placed on addressing the question of what kinds of 3D culture and system complexities are deemed desirable by the biological and biomedical community. This question is addressed through analysis of a research survey to evaluate the potential use of microfluidic cell culture models among the end users. Our results showed a willingness to adopt 3D culture technology among biomedical researchers, although a significant gap still exists between the desired systems and existing 3D culture options. With these results, key challenges and future directions are highlighted.

    Full Text Available Background In primary care settings, users often rely on vendors to provide support for health information technology (HIT. Yet, little is known about the vendors’ perspectives on the support they provide, how support personnel perceive their roles, the challenges they face and the ways they deal with them.Objective To provide in-depth insight into an electronic-medical record (EMR vendor’s perspective on end-user support.Methods As part of a larger case study research, we conducted nine semi-structured interviews with help desk staff, trainers and service managers of an EMR vendor, and observed two training sessions of a new client.Results With a growing client base, the vendor faced challenges of support staff shortage and high variance in users’ technical knowledge. Additionally, users sometimes needed assistance with infrastructure, and not just software problems. These challenges sometimes hindered the provision of timely support and required supporters to possess good interpersonal skills and adapt to diverse client population.Conclusion This study highlights the complexity of providing end-user support for HIT. With increased adoption, other vendors are likely to face similar challenges. To deal with these issues, supporters need not only strong technical knowledge of the systems, but also good interpersonal communication skills. Some responsibilities may be delegated to super-users. Users may find it useful to hire local IT staff, at least on an on-call basis, to provide assistance with infrastructure problems, which are not supported by the software vendor. Vendors may consider expanding their service packages to cover these elements.

  8. About the Bakhtinian Thought: A Reception of Receptions

    Full Text Available There are several receptions of the Bakhtinian work: those which situate it in a cultural and historical perspective, making it possible to understand the context inherent to it, the interchanges with which it was instituted and its development paths; those which separately take one or other of its ideas, and those which search to infer a less or more systemized framework from it in order to consider a specific object. When we concentrate on those last ones and on the field of studies about language, we examine the receptions of the Bakhtinian thought as a pragmatics, a sociolinguistics, a semiotics, a social theory, a theory of the discourse. The perspective of this branch of instruction is the one on which we lastly focus in order to reflect upon some of its fundamental basis.

    Efficient representation of images for human use requires an understanding of how the brain processes and represents visual information. Spatial imagery is represented in the brain in the receptive fields of visual neurons. Models of these neurons lead to models of image fidelity, and to digital implementations of these neural codes. This approach will be illustrated by two example codes. The advantages and difficulties of this approach will be discussed.

    A lack of evidence to guide the design of age-appropriate and acceptable dosage forms has been a longstanding knowledge gap in paediatric formulation development. The Children's Acceptability of Oral Formulations (CALF) study captured end-user perceptions and practices with a focus on solid oral dosage forms, namely tablets, capsules, chewables, orodispersibles, multiparticulates (administered with food) and mini-tablets (administered directly into the mouth). A rigorous development and testing phase produced age-adapted questionnaires as measurement tools with strong evidence of validity and reliability. Overall, 590 school children and adolescents, and 428 adult caregivers were surveyed across hospitals and various community settings. Attitudes towards dosage forms primarily differed based on age and prior use. Positive attitudes to tablets and capsules increased with age until around 14 years. Preference was seen for chewable and orodispersible preparations across ages, while multiparticulates were seemingly less favourable. Overall, 59.6% of school children reported willingness to take 10mm diameter tablets, although only 32.1% of caregivers perceived this size to be suitable. While not to be taken as prescriptive guidance, the results of this study provide some evidence towards rational dosage form design, as well as methodological approaches to help design tools for further evaluation of acceptability within paediatric studies.

    Background Implementation of Computerized Provider Order Entry (CPOE) has many potential advantages. Despite the potential benefits of CPOE, several attempts to implement CPOE systems have failed or met with high levels of user resistance. Implementation of CPOE can fail or meet high levels of user resistance for a variety of reasons, including lack of attention to users’ needs and the significant workflow changes required by CPOE. User satisfaction is a critical factor in information technology implementation. Little is known about how end-user satisfaction with CPOE changes over time. Objective To examine ordering provider and nurse satisfaction with CPOE implementation over time. Methods We conducted a repeated cross-sectional questionnaire survey in four intensive care units of a large hospital. We analyzed the questionnaire data as well as the responses to two open-ended questions about advantages and disadvantages of CPOE. Results Users were moderately satisfied with CPOE and there were interesting differences between user groups: ordering providers and nurses. User satisfaction with CPOE did not change over time for providers, but it did improve significantly for nurses. Results also show that nurses and providers are satisfied with different aspects of CPOE. PMID:23100129

    3D print is a recently developed technique, for single-unit production, and for structures that have been impossible to build previously. The current work presents a method to 3D print polymer bonded isotropic hard magnets with a low-cost, end-user 3D printer. Commercially available isotropic NdFeB powder inside a PA11 matrix is characterized, and prepared for the printing process. An example of a printed magnet with a complex shape that was designed to generate a specific stray field is presented, and compared with finite element simulation solving the macroscopic Maxwell equations. For magnetic characterization, and comparing 3D printed structures with injection molded parts, hysteresis measurements are performed. To measure the stray field outside the magnet, the printer is upgraded to a 3D magnetic flux density measurement system. To skip an elaborate adjusting of the sensor, a simulation is used to calibrate the angles, sensitivity, and the offset of the sensor. With this setup, a measurement resolution of 0.05 mm along the z-axes is achievable. The effectiveness of our calibration method is shown. With our setup, we are able to print polymer bonded magnetic systems with the freedom of having a specific complex shape with locally tailored magnetic properties. The 3D scanning setup is easy to mount, and with our calibration method we are able to get accurate measuring results of the stray field.

    Full Text Available Brain-computer interfaces (BCIs can serve as muscle independent communication aids. Persons, who are unable to control their eye muscles (e.g. in the completely locked-in state or have severe visual impairments for other reasons, need BCI systems that do not rely on the visual modality. For this reason, BCIs that employ auditory stimuli were suggested. In this study, a multiclass BCI spelling system was implemented that uses animal voices with directional cues to code rows and columns of a letter matrix. To reveal possible training effects with the system, 11 healthy participants performed spelling tasks on two consecutive days. In a second step, the system was tested by a participant with amyotrophic lateral sclerosis (ALS in two sessions. In the first session, healthy participants spelled with an average accuracy of 76% (3.29 bits/min that increased to 90% (4.23 bits/min on the second day. Spelling accuracy by the participant with ALS was 20% in the first and 47% in the second session. The results indicate a strong training effect for both the healthy participants and the participant with ALS. While healthy participants reached high accuracies in the first session and second session, accuracies for the participant with ALS were not sufficient for satisfactory communication in both sessions. More training sessions might be needed to improve spelling accuracies. The study demonstrated the feasibility of the auditory BCI with healthy users and stresses the importance of training with auditory multiclass BCIs, especially for potential end-users of BCI with disease.

    2016-11-23

    In primary visual cortex, a subset of neurons responds when a particular stimulus is encountered in a certain location in visual space. This activity can be modeled using a visual receptive field. In addition to visually driven activity, there are neurons in visual cortex that integrate visual and motor-related input to signal a mismatch between actual and predicted visual flow. Here we show that these mismatch neurons have receptive fields and signal a local mismatch between actual and predicted visual flow in restricted regions of visual space. These mismatch receptive fields are aligned to the retinotopic map of visual cortex and are similar in size to visual receptive fields. Thus, neurons with mismatch receptive fields signal local deviations of actual visual flow from visual flow predicted based on self-motion and could therefore underlie the detection of objects moving relative to the visual flow caused by self-motion.

  3. Social obstacles in curbing residential energy demand

    Energy Technology Data Exchange (ETDEWEB)

    2003-07-01

    The continuing growth in residential energy-use does not comply with policy targets for curbing end-user demand. Households are steadily increasing their energy-use, offsetting energy efficiency improvements, to gain time, convenience, comfort and mobility. If sustainable development presupposes lowering demand, it conflicts with present energy-driven changes in life-styles. Environmental degradation due to energy-use gives incentives to raise taxes and duties. The Norwegian experience is that rising income increase households' energy consumption while decreasing its share of total expense. Consequently, higher prices hit low-income households that account for a minor share of total household demand. Since energy represents a purchased input factor to accomplish tasks, the burden is twofold. Energy consumption losses also represent the loss of time and thus money. Additionally, these households have less financial reserves to invest in energy saving. Hence, impact of price hikes (e.g. cold weather) has a regressive social effect. This paper argues that heavy taxation of end-user energy within current practices including tax recycling or deduction, is neither advisable nor politically viable to obtain set targets. Panel data of individual households' electricity use in Oslo suggests that low-income households can not counteract sudden price-hikes but adjust long-term, while the opposite applies to high-income households. In the discussion on environmental policy towards energy-use, the socio-economic effect of measures must be emphasised. New conceptualisations of the world-wide problems in energy and mobility that transforms into agreements on e.g. emission control, can result in added burdens on the poor in industrialised countries rather than the developing countries at large.

    This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of uncertainty resolution found in productivity heterogeneity models...... in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit. This prediction reconciles...

  5. A computational theory of visual receptive fields.

    Science.gov (United States)

    Lindeberg, Tony

    2013-12-01

    A receptive field constitutes a region in the visual field where a visual cell or a visual operator responds to visual stimuli. This paper presents a theory for what types of receptive field profiles can be regarded as natural for an idealized vision system, given a set of structural requirements on the first stages of visual processing that reflect symmetry properties of the surrounding world. These symmetry properties include (i) covariance properties under scale changes, affine image deformations, and Galilean transformations of space-time as occur for real-world image data as well as specific requirements of (ii) temporal causality implying that the future cannot be accessed and (iii) a time-recursive updating mechanism of a limited temporal buffer of the past as is necessary for a genuine real-time system. Fundamental structural requirements are also imposed to ensure (iv) mutual consistency and a proper handling of internal representations at different spatial and temporal scales. It is shown how a set of families of idealized receptive field profiles can be derived by necessity regarding spatial, spatio-chromatic, and spatio-temporal receptive fields in terms of Gaussian kernels, Gaussian derivatives, or closely related operators. Such image filters have been successfully used as a basis for expressing a large number of visual operations in computer vision, regarding feature detection, feature classification, motion estimation, object recognition, spatio-temporal recognition, and shape estimation. Hence, the associated so-called scale-space theory constitutes a both theoretically well-founded and general framework for expressing visual operations. There are very close similarities between receptive field profiles predicted from this scale-space theory and receptive field profiles found by cell recordings in biological vision. Among the family of receptive field profiles derived by necessity from the assumptions, idealized models with very good qualitative

    Multi-model ensembles (MMEs) are powerful tools in dynamical climate prediction as they account for the overconfidence and the uncertainties related to single-model ensembles. Previous works suggested that the potential benefit that can be expected by using a MME amplifies with the increase of the independence of the contributing Seasonal Prediction Systems. In this work we combine the two MME Seasonal Prediction Systems (SPSs) independently developed by the European (ENSEMBLES) and by the Asian-Pacific (APCC/CliPAS) communities. To this aim, all the possible multi-model combinations obtained by putting together the 5 models from ENSEMBLES and the 11 models from APCC/CliPAS have been evaluated. The grand ENSEMBLES-APCC/CliPAS MME enhances significantly the skill in predicting 2m temperature and precipitation compared to previous estimates from the contributing MMEs. Our results show that, in general, the better combinations of SPSs are obtained by mixing ENSEMBLES and APCC/CliPAS models and that only a limited number of SPSs is required to obtain the maximum performance. The number and selection of models that perform better is usually different depending on the region/phenomenon under consideration so that all models are useful in some cases. It is shown that the incremental performance contribution tends to be higher when adding one model from ENSEMBLES to APCC/CliPAS MMEs and vice versa, confirming that the benefit of using MMEs amplifies with the increase of the independence the contributing models. To verify the above results for a real world application, the Grand ENSEMBLES-APCC/CliPAS MME is used to predict retrospective energy demand over Italy as provided by TERNA (Italian Transmission System Operator) for the period 1990-2007. The results demonstrate the useful application of MME seasonal predictions for energy demand forecasting over Italy. It is shown a significant enhancement of the potential economic value of forecasting energy demand when using the

  12. The politics, science, and art of receptivity

    Directory of Open Access Journals (Sweden)

    Emily Beausoleil

    2014-03-01

    Full Text Available With so much attention on the issue of voice in democratic theory, the inverse question of how people come to listen remains a marginal one. Recent scholarship in affect and neuroscience reveals that cognitive and verbal strategies, while privileged in democratic politics, are often insufficient to cultivate the receptivity that constitutes the most basic premise of democratic encounters. This article draws on this scholarship and a recent case of forum theatre to examine the conditions of receptivity and responsiveness, and identify specific strategies that foster such conditions. It argues that the forms of encounter most effective in cultivating receptivity are those that move us via affective intensity within pointedly mediated contexts. It is this constellation of strategies—this strange marriage of immersion and mediation—that enabled this performance to surface latent memory, affect and bias, unsettle entrenched patterns of thought and behaviour, and provide the conditions for revisability. This case makes clear that to lie beyond the domain of cognitive and verbal processes is not to lie beyond potential intervention, and offers insight to how such receptivity might be achieved in political processes more broadly.

    Full Text Available The present study investigates, (i English as Foreign Language (EFL learners’ receptive collocational knowledge growth in relation to their linguistic proficiency level; (ii how much receptive collocational knowledge is acquired as proficiency develops; and (iii the extent to which receptive knowledge of collocations of EFL learners varies across word frequency bands. A proficiency measure and a collocation test were administered to English majors at the University of Burundi. Results of the study suggest that receptive collocational competence develops alongside EFL learners’ linguistic proficiency; which lends empirical support to Gyllstad (2007, 2009 and Author (2011 among others, who reported similar findings. Furthermore, EFL learners’ collocations growth seems to be quantifiable wherein both linguistic proficiency level and word frequency occupy a crucial role. While more gains in terms of collocations that EFL learners could potentially add as a result of change in proficiency are found at lower levels of proficiency; collocations of words from more frequent word bands seem to be mastered first, and more gains are found at more frequent word bands. These results confirm earlier findings on the non-linearity nature of vocabulary growth (cf. Meara 1996 and the fundamental role played by frequency in word knowledge for vocabulary in general (Nation 1983, 1990, Nation and Beglar 2007, which are extended here to collocations knowledge.

  18. Language, gay pornography, and audience reception.

    Science.gov (United States)

    Leap, William L

    2011-01-01

    Erotic imagery is an important component of gay pornographic cinema, particularly, where work of audience reception is concerned. However, to assume the audience engagement with the films is limited solely to the erotic realm is to underestimate the workings of ideological power in the context and aftermath of reception. For example, the director of the film under discussion here (Men of Israel; Lucas, 2009b) intended to present an erotic celebration of the nation-state. Yet, most viewers ignore the particulars of context in their comments about audience reception, placing the "Israeli" narrative within a broader framework, using transnational rather than film-specific criteria to guide their "reading" of the Israeli-centered narrative. This article uses as its entry point the language that viewers employ when describing their reactions to Men of Israel on a gay video club's Web site; this article shows how the work of audience reception may draw attention to a film's erotic details while invoking social and political messages that completely reframe the film's erotic narrative.

    Satellite data of atmospheric pollutants are becoming more widely used in the decision-making and environmental management activities of public, private sector and non-profit organizations. They are employed for estimating emissions, tracking pollutant plumes, supporting air quality forecasting activities, providing evidence for "exceptional event" declarations, monitoring regional long-term trends, and evaluating air quality model output. However, many air quality managers are not taking full advantage of the data for these applications nor has the full potential of satellite data for air quality applications been realized. A key barrier is the inherent difficulties associated with accessing, processing, and properly interpreting observational data. A degree of technical skill is required on the part of the data end-user, which is often problematic for air quality agencies with limited resources. Therefore, we 1) review the primary uses of satellite data for air quality applications, 2) provide some background information on satellite capabilities for measuring pollutants, 3) discuss the many resources available to the end-user for accessing, processing, and visualizing the data, and 4) provide answers to common questions in plain language.

    Nguyen, Daniel Xuyen

    This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of uncertainty resolution found in productivity heterogeneity models...... the high rate of exit seen in the first years of exporting. Finally, when faced with multiple countries in which to export, some firms will choose to sequentially export in order to slowly learn more about its chances for success in untested markets....

    2009-07-15

    In this comprehensive final report, made by TEP Energy GmbH - Technology Economics Policy - Research and Advice - a spin-off company of ETH Zuerich for the Swiss gas and oil industries, the effective CO{sub 2} intensities involved in Swiss electricity consumption are calculated and discussed. The authors present details on how CO{sub 2} emissions should be calculated on the basis of figures both on Swiss power generation and, also, on electricity imports and exports in a European context. Daily and seasonal export-import balances are discussed. In particular the authors note that the actual production-mix for electricity in Switzerland should not be used as a basis for judging actual consumption. Three methods for viewing Swiss electricity consumption involving net and gross power export and import are introduced and discussed. The determination of the CO{sub 2} intensity of Swiss power is discussed, as are power demand profiles and international agreements. The results obtained using the three methods used are presented and discussed. Future developments are also examined. The report is completed with an appendix.

    2015-01-01

    Full Text Available Smart homes (SHs are crucial parts for demand response management (DRM of smart grid (SG. The aim of SHs based demand response (DR is to provide a flexible two-way energy feedback whilst (or shortly after the consumption occurs. It can potentially persuade end-users to achieve energy saving and cooperate with the electricity producer or supplier to maintain balance between the electricity supply and demand through the method of peak shaving and valley filling. However, existing solutions are challenged by the lack of consideration between the wide application of fiber power cable to the home (FPCTTH and related users’ behaviors. Based on the new network infrastructure, the design and development of smart DR systems based on SHs are related with not only functionalities as security, convenience, and comfort, but also energy savings. A new multirouting protocol based on Kruskal’s algorithm is designed for the reliability and safety of the SHs distribution network. The benefits of FPCTTH-based SHs are summarized at the end of the paper.

    Emmanuel Chifuel Manasseh

    2014-12-01

    Full Text Available This study considers load control in a multi-residential setup where energy scheduler (ES devices installed in smart meters are employed for demand-side management (DSM. Several residential end-users share the same energy source and each residential user has non-adjustable loads and adjustable loads. In addition, residential users may have storage devices and renewable energy sources such as wind turbines or solar as well as dispatchable generators. The ES devices exchange information automatically by executing an iterative distributed algorithm to locate the optimal energy schedule for each end-user. This will reduce the total energy cost and the peak-to-average ratio (PAR in energy demand in the electric power distribution. Users possessing storage devices and dispatchable generators strategically utilise their resources to minimise the total energy cost together with the PAR. Simulation results are provided to evaluate the performance of the proposed game theoretic-based distributed DSM technique.

    On the 150th anniversary of Eugen Bleuler's birth, this article examines his reception of Sigmund Freud and his use of Freudian theory to understand the symptoms of schizophrenia. In addition, in contrast to earlier interpretations of Bleuler's relationship with Freud in terms of an eventual personal and theoretical incompatibility, the article demonstrates that, although Bleuler did distance himself from the psychoanalytic movement, he remained consistent in his views on Freud's theories.

  10. Enhanced AIS receiver design for satellite reception

    Clazzer, Federico; Lázaro, Francisco; Plass, Simon

    2016-12-01

    The possibility to detect Automatic Identification System (AIS) messages from low earth orbit (LEO) satellites paves the road for a plurality of new and unexplored services. Besides worldwide tracking of vessels, maritime traffic monitoring, analysis of vessel routes employing big data, and oceans monitoring are just few of the fields, where satellite-aided AIS is beneficial. Designed for ship-to-ship communication and collision avoidance, AIS satellite reception performs poorly in regions with a high density of vessels. This calls for the development of advanced satellite AIS receivers able to improve the decoding capabilities. In this context, our contribution focuses on the introduction of a new enhanced AIS receiver design and its performance evaluation. The enhanced receiver makes use of a coherent receiver for the low signal-to-noise ratio (SNR) region, while for medium to high SNRs, a differential Viterbi receiver is used. Additional novelty of our work is in the exploitation of previously decoded packets from one vessel that is still under the LEO reception range, to improve the vessel detection probability. The assessment of the performance against a common receiver is done making the use of a simple and tight model of the medium access (MAC) layer and the multi-packet reception (MPR) matrix for physical layer (PHY) representation. Performance results show the benefits of such enhanced receiver, especially when it is bundled with successive interference cancellation (SIC).

    Full Text Available Reception staff loyalty is much influenced by several factors, one of them is job satisfaction. Employee job satisfaction plays important role in creating employee loyalty. For hoteliers who serve as provider of accommodation services, the demand for the creation of quality human resources is maximum achievement. One of the important section in the front office is receptionist. Today, hoteliers pay very close attention because the employee turnover will certainly affect the consistency of services offered by the hotel. Therefore, the hotel is getting active in increasing the satisfaction of its staff in order to minimize employee turnover especially in a very important role such the receptionist. Although the validity of the relationship between job satisfaction and reception staff loyalty is still an exciting debate, the result of the research conducted in the Hotel X is expected to help increase employee satisfaction in order to create quality of life that will improve labor productivity.

    2015-03-01

    Full Text Available This article intends to focus on the difficulty encountered by Werner Sombart’s works in gaining a hearing in various Italian intellectual circuits. As is well known, Sombart belonged to the German Historical School of economics, sharing with other scholars of that school the same problems in getting his work known in Italy. Our aim is to explain the reason for this hostile reception. First of all, we will analyze the factors which generally hindered the spread of the German Historical School in Italy, recognizing in economists like Francesco Ferrara, Idealists like Benedetto Croce and Marxists like Antonio Labriola some of its strongest opponents. We will dwell on the cases of Gustav Schmoller and Max Weber, in order to give two representative examples of the slow and complicated Italian reception of methodological approaches and analytical perspectives which characterized the scientific experience of the German Historical School. Secondly, we will try to show why Sombart was even less appreciated than other German social scientists, giving the reasons that attracted severe criticism from economists, economic historians and sociologists towards his interdisciplinary approach in the analysis of modern capitalism. Finally, we will show the reasons of the contemporary rediscovery of Sombart and of his works.

  4. Modeling and Analysis of Commercial Building Electrical Loads for Demand Side Management

    Science.gov (United States)

    Berardino, Jonathan

    In recent years there has been a push in the electric power industry for more customer involvement in the electricity markets. Traditionally the end user has played a passive role in the planning and operation of the power grid. However, many energy markets have begun opening up opportunities to consumers who wish to commit a certain amount of their electrical load under various demand side management programs. The potential benefits of more demand participation include reduced operating costs and new revenue opportunities for the consumer, as well as more reliable and secure operations for the utilities. The management of these load resources creates challenges and opportunities to the end user that were not present in previous market structures. This work examines the behavior of commercial-type building electrical loads and their capacity for supporting demand side management actions. This work is motivated by the need for accurate and dynamic tools to aid in the advancement of demand side operations. A dynamic load model is proposed for capturing the response of controllable building loads. Building-specific load forecasting techniques are developed, with particular focus paid to the integration of building management system (BMS) information. These approaches are tested using Drexel University building data. The application of building-specific load forecasts and dynamic load modeling to the optimal scheduling of multi-building systems in the energy market is proposed. Sources of potential load uncertainty are introduced in the proposed energy management problem formulation in order to investigate the impact on the resulting load schedule.

As expected we find clear evidence of an exploitation of locked-in customers through expensive standard variable rate agreements. One also find evidence that the extent of this utilization have increased after power providers began to use price discrimination of customers more actively. Vendors say the exploitation of locked-in customers have held out for and utilization is often seen as the biggest problem for the market. In time to come, it is not however given that exploitation of locked-customers, through expensive standard variable rate agreements, will continue to be the biggest problem with the market. Today, 60% of households are connected to the spot price contract, and such a percentage would indicate less use of customers. Electricity suppliers uses hand spot agreements without notification to exploit uncertainty customers have about competitive premiums. Agreements without notification will not be registered in this summary power to the Competition Authority and the agreements are therefore difficult to compare for customers. Today, over half of the spot price agreements without notification, and power providers achieve much greater profit on these agreements than the spot price agreements with notification.(eb)

  11. The reception of relativity in China.

    Hu, Danian

    2007-09-01

    Having introduced the theory of relativity from Japan, the Chinese quickly and enthusiastically embraced it during the May Fourth Movement, virtually without controversy. This unique passion for and openness to relativity, which helped advance the study of theoretical physics in China in the 1930s, was gradually replaced by imported Soviet criticism after 1949. During the Cultural Revolution, radical Chinese ideologues sponsored organized campaigns against Einstein and relativity, inflicting serious damage on Chinese science and scientific education. China's economic reforms in the late 1970s empowered scientists and presented them with the opportunity to rehabilitate Einstein and call for social democracy. Einstein has since become the symbol in China of the unity of science and democracy, the two eminent objectives of the May Fourth Movement that remain to be achieved in full. Using the reception of relativity as a case study, the essay also discusses issues involving the historical study of modern Chinese science.

  12. Uterine receptivity and the plasma membrane transformation

    2004-01-01

    This review begins with a brief commentary on the diversity of placentation mechanisms, and then goes on to examine the extensive alterations which occur in the plasma membrane of uterine epithelial cells during early pregnancy across species. Ultrastructural, biochemical and more general morphological data reveal that strikingly common phenomena occur in this plasma membrane during early pregnancy despite the diversity of placental types-from epitheliochorial to hemochorial, which ultimately form in different species. To encapsulate the concept that common morphological and molecular alterations occur across species, that they are found basolaterally as well as apically, and that moreover they are an ongoing process during much of early pregnancy, not just an event at the time attachment,brane during early pregnancy are key to uterine receptivity.

  13. The neuropolitical habitus of resonant receptive democracy

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available In this paper, I argue that the recent work on mirror neurons illuminates the character of our capacities for a politics of resonant receptivity in ways that both help us to comprehend the damages of our contemporary order and suggest indispensable alternative ethical–strategic registers and possible directions for organising a powerful movement towards radical democracy. In doing so, neuroscience simultaneously contributes to our understanding of the possibility and importance of a more durable (less fugitive radically democratic habitus. While the trope, ‘radically democratic habitus’, may seem oxymoronic in light of Bourdieu's extensive rendering of ‘habitus’, I suggest that research on mirror neurons discloses ways in which iterated practices and dispositional structures are crucial for democratic freedom.

  14. The reception of relativity in the Netherlands

    2013-01-01

    This article reviews the early academic and public reception of Albert Einstein's theory of relativity in the Netherlands, particularly after Arthur Eddington's eclipse experiments of 1919. Initially, not much attention was given to relativity, as it did not seem an improvement over Hendrik A. Lorentz' work. This changed after the arrival in Leiden of Paul Ehrenfest. Soon relativity was much studied and lead to controversy among a number of conservative intellectuals, as elsewhere in Europe. The tone of Dutch critics was much more mild, however. This can be understood when one considers Dutch neutrality during World War I. Einstein's political positions were generally positively perceived in Holland, which Dutch academics put to use in their efforts at international reconciliation abroad, and the presentation of theoretical physics at home.

    2006-12-15

    Using a unique database of end-user local energy data and the recently developed Autoregressive Distributed Lag (ARDL) bounds testing approach to cointegration, we estimate the long-run elasticities of the Namibian energy demand function at both aggregated level and by type of energy (electricity, petrol and diesel) for the period 1980-2002. Our main results show that energy consumption responds positively to changes in GDP and negatively to changes in energy price and air temperature. The differences in price elasticities across fuels uncovered by this study have significant implications for energy taxation by Namibian policy makers. We do not find any significant cross-price elasticities between different fuel types. (author)

  16. Invariance of visual operations at the level of receptive fields.

    Science.gov (United States)

    Lindeberg, Tony

    2013-01-01

    The brain is able to maintain a stable perception although the visual stimuli vary substantially on the retina due to geometric transformations and lighting variations in the environment. This paper presents a theory for achieving basic invariance properties already at the level of receptive fields. Specifically, the presented framework comprises (i) local scaling transformations caused by objects of different size and at different distances to the observer, (ii) locally linearized image deformations caused by variations in the viewing direction in relation to the object, (iii) locally linearized relative motions between the object and the observer and (iv) local multiplicative intensity transformations caused by illumination variations. The receptive field model can be derived by necessity from symmetry properties of the environment and leads to predictions about receptive field profiles in good agreement with receptive field profiles measured by cell recordings in mammalian vision. Indeed, the receptive field profiles in the retina, LGN and V1 are close to ideal to what is motivated by the idealized requirements. By complementing receptive field measurements with selection mechanisms over the parameters in the receptive field families, it is shown how true invariance of receptive field responses can be obtained under scaling transformations, affine transformations and Galilean transformations. Thereby, the framework provides a mathematically well-founded and biologically plausible model for how basic invariance properties can be achieved already at the level of receptive fields and support invariant recognition of objects and events under variations in viewpoint, retinal size, object motion and illumination. The theory can explain the different shapes of receptive field profiles found in biological vision, which are tuned to different sizes and orientations in the image domain as well as to different image velocities in space-time, from a requirement that the

    Full Text Available After the description of the main migration routes toward Italian territory, the article provides an overview of the laws and administrative policy instruments that characterize the system of reception and detention of migrants in Italy. This type of information can help psychosocial workers supporting migrants to better cope with various psychosocial issues, such as the landing in a foreign country. Following a report on the first reception intervention carried out in Palermo, Sicily, by Psicologi per i Popoli – Sicilia, some reflections about the strengths and weaknesses identified as well as the potential for a greater involvement of psychosocial teams in immigrants reception and detention processes are presented. In fact, psychological science may improve the quality and effectiveness of the emergency services provided to migrants and be useful both in the training of workers and in crisis and emergency risk communication, with particular reference to risk perception about infectious diseases. However, the “added value” of psychological intervention might remain concealed and its usefulness may appear unimpressive. For this reason the papers suggests some principles through which psychology can contribute to processes of inclusiveness within a multicultural society and promote the acknowledgement of its own role in the field of humanitarian intervention.

    2015-04-01

    Matching the availability of water to its demand in Europe is a major challenge for the future due to expected economic and demographic developments and climate change. This means there is a growing need to estimate future water demand and to optimize the water allocation to all end users to counteract welfare loss. At the European scale it is currently not possible to assess the impact of social and economic changes on future water demand or to prioritize water allocation amongst different sectors based on economic damage without extensive use of assumptions and generalizations. Indeed, our review of existing regional optimization models for Europe reveals that the social-economic component of the water use system needs to be improved by complementing them with detailed water use estimates and cost/benefit functions in order to determine the optimal situation. Our study contributes to closing this knowledge gap for the European household sector by quantifying future water demand and the effect of water pricing, as well as providing a method for the calculation of monetary damage due to unmet demand at the highest spatial resolution possible. We used a water demand function approach in which household water consumption depends upon some exogenous drivers including water price, household income, population and household characteristics and climate conditions. For each European country, the annual water consumption per capita was calculated at regional level (NUTS3) and subsequently disaggregated to five kilometer grid level based on a population density map. In order to produce estimates of water demand, the evolution of the explanatory variables of the water demand functions and population density map were simulated until 2050 based on related variables such as GDP and demographic projections. The results of this study will be integrated into the JRC hydro-economic modelling framework for an assessment of the Water-Agriculture-Energy-Ecosystems Nexus.

  1. External quality assessment of reading and interpretation of malaria rapid diagnostic tests among 1849 end-users in the Democratic Republic of the Congo through Short Message Service (SMS.

    Directory of Open Access Journals (Sweden)

    Pierre Mukadi

    Full Text Available BACKGROUND: Although malaria rapid diagnostic tests (RDT are simple to perform, they remain subject to errors, mainly related to the post-analytical phase. We organized the first large scale SMS based external quality assessment (EQA on correct reading and interpretation of photographs of a three-band malaria RDT among laboratory health workers in the Democratic Republic of the Congo (DR Congo. METHODS AND FINDINGS: High resolution EQA photographs of 10 RDT results together with a questionnaire were distributed to health facilities in 9 out of 11 provinces in DR Congo. Each laboratory health worker answered the EQA by Short Message Service (SMS. Filled-in questionnaires from each health facility were sent back to Kinshasa. A total of 1849 laboratory health workers in 1014 health facilities participated. Most frequent errors in RDT reading were i failure to recognize invalid (13.2-32.5% or negative test results (9.8-12.8%, (ii overlooking faint test lines (4.1-31.2% and (iii incorrect identification of the malaria species (12.1-17.4%. No uniform strategy for diagnosis of malaria at the health facility was present. Stock outs of RDTs occurred frequently. Half of the health facilities had not received an RDT training. Only two thirds used the RDT recommended by the National Malaria Control Program. Performance of RDT reading was positively associated with training and the technical level of health facility. Facilities with RDT positivity rates >50% and located in Eastern DR Congo performed worse. CONCLUSIONS: Our study confirmed that errors in reading and interpretation of malaria RDTs are widespread and highlighted the problem of stock outs of RDTs. Adequate training of end-users in the application of malaria RDTs associated with regular EQAs is recommended.

    Non-cigarette tobacco marketing is less regulated and may promote cigarette smoking among adolescents. We quantified receptivity to advertising for multiple tobacco products and hypothesized associations with susceptibility to cigarette smoking. Wave 1 of the nationally representative PATH (Population Assessment of Tobacco and Health) study interviewed 10 751 adolescents who had never used tobacco. A stratified random selection of 5 advertisements for each of cigarettes, e-cigarettes, smokeless products, and cigars were shown from 959 recent tobacco advertisements. Aided recall was classified as low receptivity, and image-liking or favorite ad as higher receptivity. The main dependent variable was susceptibility to cigarette smoking. Among US youth, 41% of 12 to 13 year olds and half of older adolescents were receptive to at least 1 tobacco advertisement. Across each age group, receptivity to advertising was highest for e-cigarettes (28%-33%) followed by cigarettes (22%-25%), smokeless tobacco (15%-21%), and cigars (8%-13%). E-cigarette ads shown on television had the highest recall. Among cigarette-susceptible adolescents, receptivity to e-cigarette advertising (39.7%; 95% confidence interval [CI]: 37.9%-41.6%) was higher than for cigarette advertising (31.7%; 95% CI: 29.9%-33.6%). Receptivity to advertising for each tobacco product was associated with increased susceptibility to cigarette smoking, with no significant difference across products (similar odds for both cigarette and e-cigarette advertising; adjusted odds ratio = 1.22; 95% CI: 1.09-1.37). A large proportion of US adolescent never tobacco users are receptive to tobacco advertising, with television advertising for e-cigarettes having the highest recall. Receptivity to advertising for each non-cigarette tobacco product was associated with susceptibility to smoke cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

After reviewing the historical origins of reception theory in reader response and its later appropriation by communication and cultural studies, I argue that a mixed discursive perspective offers a potential refinement of contemporary reception theory as applicable to new media production, in which technological abstractions and complexities may be rich for purposes of production, but fall short in appreciation and communicative value for an audience

    Full Text Available The creation of a Europe-wide electricity market combined with the increased intermittency of supply from renewable sources calls for an investigation into the risk of aggregate peak demand. This paper makes use of a risk model to assess differences in time-use data from residential end-users in five different European electricity markets. Drawing on the Multinational Time-Use Survey database, it assesses risk in relation to the probability of electrical appliance use within households for five European countries. Findings highlight in which countries and for which activities the risk of aggregate peak demand is higher and link smart home solutions (automated load control, dynamic pricing and smart appliances to different levels of peak demand risk.

    The total demand for communications services, and satellite transmission services at the 4/6 GHz, 12/14 GHz, and 18/30 GHz frequencies is assessed. The services are voice, video, and data services. Traffic demand, by service, is distributed by geographical regions, population density, and distance between serving points. Further distribution of traffic is made among four major end user groups: business, government, institutions and private individuals. A traffic demand analysis is performed on a typical metropolitan city to examine service distribution trends. The projected cost of C and Ku band satellite systems are compared on an individual service basis to projected terrestrial rates. Separation of traffic between transmission systems, including 18/30 GHz systems, is based on cost, user, and technical considerations.

  8. Everyday Citizenship: Identity Claims and Their Reception

    Directory of Open Access Journals (Sweden)

    Nick Hopkins

    2015-10-01

    Full Text Available Citizenship involves being able to speak and be heard as a member of the community. This can be a formal right (e.g., a right to vote. It can also be something experienced in everyday life. However, the criteria for being judged a fellow member of the community are multiple and accorded different weights by different people. Thus, although one may self-define alongside one’s fellows, the degree to which these others reciprocate depends on the weight they give to various membership criteria. This suggests we approach everyday community membership in terms of an identity claims-making process in which first, an individual claims membership through invoking certain criteria of belonging, and second, others evaluate that claim. Pursuing this logic we report three experiments investigating the reception of such identity-claims. Study 1 showed that in Scotland a claim to membership of the national ingroup was accepted more if couched in terms of place of birth and ancestry rather than just in terms of one’s subjective identification. Studies 2 and 3 showed that this differential acceptance mattered for the claimant’s ability to be heard as a community member. We discuss the implications of these studies for the conceptualization of community membership and the realization of everyday citizenship rights.

  9. Middle Byzantine Historiography: Tradition, Innovation, and Reception

    2015-10-01

    Full Text Available This paper provides an overview of Greek historical writing of the Middle Byzantine period (approx. 800 until 1000 A.D., with a particular focus on the major chronicles, such as Theophanesthe Confessor (early 9th c., George the Monk (probably late 9th c., and Symeon the Logothete (second half of the 10th c.. On the one hand, it is discussed how the chroniclers engage with tradition and either accept it or reject it. Acceptance of tradition is illustrated by many cases where chroniclers keep very close to the narrative modes of their predecessors and in particular where they copy them extensively. Rejection of, or at least deviation from tradition is illustrated by many cases where new narrative techniques and modes of expression are apparent. Particular attention is paid to some aspects of narrative technique which seem to be innovative. In short, there seems to be an increased tendency towards greater logical (and hence, narrative coherence in the chronicles and an increased tendency towards concentration on a small number of settings, issues and persons (in particular, there is an increased concentration on the Capital of Constantinople and the Emperor’s person. Further, reception is discussed, and especially how Middle Byzantine historical texts were read and used in later writings, including the Slavic literatures. The need for further research in order to understand the transmission processes, especially in the form of the philological study of manuscripts, is stressed.

  10. Fostering Residential Demand Response through Dynamic Pricing Schemes: A Behavioural Review of Smart Grid Pilots in Europe

    Directory of Open Access Journals (Sweden)

    Kris Kessels

    2016-09-01

    Full Text Available Many smart grid projects make use of dynamic pricing schemes aimed to motivate consumers to shift and/or decrease energy use. Based upon existing literature and analyses of current smart grid projects, this survey paper presents key lessons on how to encourage households to adjust energy end use by means of dynamic tariffs. The paper identifies four key hypotheses related to fostering demand response through dynamic tariff schemes and examines whether these hypotheses can be accepted or rejected based on a review of published findings from a range of European pilot projects. We conclude that dynamic pricing schemes have the power to adjust energy consumption behavior within households. In order to work effectively, the dynamic tariff should be simple to understand for the end users, with timely notifications of price changes, a considerable effect on their energy bill and, if the tariff is more complex, the burden for the consumer could be eased by introducing automated control. Although sometimes the mere introduction of a dynamic tariff has proven to be effective, often the success of the pricing scheme depends also on other factors influencing the behavior of end users. An important condition to make dynamic tariffs work is that the end users should be engaged with them.

    Basic cognitive functions such as: alertness, working memory, long term memory and perception, as well as higher levels of cognitive functions like: speech and language, decision-making and executive functions are affected by aging processes. Relations between the receptive vocabulary and cognitive functioning, and the manifestation of differences between populations of elderly people based on the primary disease is in the focus of this study. To examine receptive vocabulary and cognition of elderly people with: verified stroke, dementia, verified stroke and dementia, and without the manifested brain disease. The sample consisted of 120 participants older than 65 years, living in an institution. A total of 26 variables was analyzed and classified into three groups: case history/anamnestic, receptive vocabulary assessment, and cognitive assessments. The interview with social workers, nurses and caregivers, as well as medical files were used to determine the anamnestic data. A Montreal Cognitive Assessment Scale (MoCA) was used for the assessment of cognition. In order to estimate the receptive vocabulary, Peabody Picture Vocabulary Test was used. Mean raw score of receptive vocabulary is 161.58 (+-21:58 points). The best results for cognitive assessment subjects achieved on subscales of orientation, naming, serial subtraction, and delayed recall. Discriminative analysis showed the significant difference in the development of receptive vocabulary and cognitive functioning in relation to the primary disease of elderly people. The biggest difference was between subjects without manifested brain disease (centroid = 1.900) and subjects with dementia (centroid = -1754). There is a significant difference between elderly with stroke; dementia; stroke and dementia, and elderly people without manifested disease of the brain in the domain of receptive vocabulary and cognitive functioning.

    2008-01-01

    This longitudinal study examined the influence of alcohol advertising and promotions on the initiation of alcohol use. A measure of receptivity to alcohol marketing was developed from research about tobacco marketing. Recall and recognition of alcohol brand names were also examined. Data were obtained from in-class surveys of sixth, seventh, and eighth graders at baseline and 12-month follow-up. Participants who were classified as never drinkers at baseline (n = 1,080) comprised the analysis sample. Logistic regression models examined the association of advertising receptivity at baseline with any alcohol use and current drinking at follow-up, adjusting for multiple risk factors, including peer alcohol use, school performance, risk taking, and demographics. At baseline, 29% of never drinkers either owned or wanted to use an alcohol branded promotional item (high receptivity), 12% students named the brand of their favorite alcohol ad (moderate receptivity), and 59% were not receptive to alcohol marketing. Approximately 29% of adolescents reported any alcohol use at follow-up; 13% reported drinking at least 1 or 2 days in the past month. Never drinkers who reported high receptivity to alcohol marketing at baseline were 77% more likely to initiate drinking by follow-up than those were not receptive. Smaller increases in the odds of alcohol use at follow-up were associated with better recall and recognition of alcohol brand names at baseline. Alcohol advertising and promotions are associated with the uptake of drinking. Prevention programs may reduce adolescents' receptivity to alcohol marketing by limiting their exposure to alcohol ads and promotions and by increasing their skepticism about the sponsors' marketing tactics.

  16. Numerical Simulation of Receptivity for a Transition Experiment

    2000-01-01

    The cost of fuel to overcome turbulence induced viscous drag on a commercial airplane constitutes a significant fraction of the operating cost of an airline. Achieving laminar flow and maintaining it over a large portion of the wing can significantly reduce the viscous drag, and hence the cost. Design of such laminar-flow-control wings and their practical operation requires the ability to accurately and reliably predict the transition from laminar to turbulent flow. The transition process begins with the conversion of environmental and surface disturbances into the instability waves of the flow by a process called receptivity. The goal of the current research project has been to improve the prediction of transition through a better understanding of the physics of receptivity. The initial objective of this work was to investigate the specific stability and receptivity characteristics of a particular experimental investigation of boundary layer receptivity at NASA Langley. Some simulation results using direct solutions of the linearized Navier-Stokes equations which modeled this experiment where presented in the 1999 APS DFD meeting. However, based on these initial investigations, it became clear that to cover the vast receptivity parameter space required for a practical transition prediction tool, more efficient methods would be required. Thus, the focus of this research was shifted from modeling this particular experiment to formulating and developing new techniques that could efficiently yet accurately predict receptivity for a wide range of disturbance conditions.

    Full Text Available Stigma  receptivity based on seed set and pollen  tubes growth  following controlled pollination of flowers  of different  ages was examined  in Melaleuca alternifolia. The stigma secretion during 10 days after anthesis and pollen viability under three different temperatures and five storage times were also observed. These series of research were undertaken because successful controlled pollination of M. alternifolia depends on the application of viable pollen to the receptive compatible  stigma. The objective of this research was therefore to determine the stigma receptivity and pollen viability of M. alternifolia. Results showed that the stigma receptivity began to develop  on day  one and finished  on day  seven after anthesis,  peak receptivity occurred from day three to day six. The stigma receptivity also coincides with the appearance of secretion in the stigma, occurring  from day three to day seven after anthesis. Therefore,  the time for pollination of M. alternifolia appeared to extend for  approximately 7 days after anthesis. Data for M. alternifolia showed that regardless of storage temperature, pollen  was still  viable  after 26 weeks  of storage;  results also demonstrated  that the lowest temperature  (-18oC was the best regime for long term storage.

    The electric fish Apteronotus leptorhynchus emits a high-frequency electric organ discharge (EOD) sensed by specialized electroreceptors (P-units). Amplitude modulations (AMs) of the EOD are caused by objects such as prey as well as by social interactions with conspecifics. The firing rate of P-units is modulated by the AMs due to both objects and communication signals. P-units trifurcate as they enter the medulla; they terminate topographically with three maps of the electrosensory lateral line lobe (ELL): the centromedial (CMS), centrolateral (CLS), and lateral (LS) segments. Within each map P-units terminate onto the basal dendrites of pyramidal cells. Anterograde filling of P-units and retrograde filling of the basal bushes of pyramidal cells were used to estimate their respective spreads and spacing in the three maps. These estimates were used to compute the receptive field structure of the pyramidal cells: receptive fields were small in CMS and very large in LS with intermediate values in CLS. There are several classes of pyramidal cells defined by morphological and functional criteria; these cells are organized into columns such that each column contains one member of each class and all cells within a column receive the same P-unit input.

    A method and apparatus for distributed parallel messaging in a parallel computing system. A plurality of DMA engine units are configured in a multiprocessor system to operate in parallel, one DMA engine unit for transferring a current packet received at a network reception queue to a memory location in a memory FIFO (rmFIFO) region of a memory. A control unit implements logic to determine whether any prior received packet destined for that rmFIFO is still in a process of being stored in the associated memory by another DMA engine unit of the plurality, and prevent the one DMA engine unit from indicating completion of storing the current received packet in the reception memory FIFO (rmFIFO) until all prior received packets destined for that rmFIFO are completely stored by the other DMA engine units. Thus, there is provided non-locking support so that multiple packets destined for a single rmFIFO are transferred and stored in parallel to predetermined locations in a memory.

    Service Oriented Architecture(SOA)and Service Oriented Computing(SOC)are prevailing technologies for sharing and reusing resources.Service composition is an envisioned methodology used in SOA and SOC to build value-added services.The existed service composition models are mostly information technology expert-oriented and there is few considering the requirement from the point of view of end-users.Different with the IT experts.who can express their requirements using precise and well-formed formal language and understand the formal description of web service,the end-users are unnecessarily to be sophisticated on the complicated knowledge of computer science and are prone to consider the service composition in fuzzy and rough fashions.There's seldom work carried on considering the contradiction between the vague and uncertain requirements of end-user and the precise and deterministic process of service composition.Granular computing is a kind of promising methodology for solving the fuzzy and rough problems in artificial intelligence,interval theory,rough set theory and cluster analysis,etc.The basic idea of granular computing is problem solving with different granularities,which can be used in service composition to solve the aforementioned contradiction intuitively,that is,it can be used to create a multi-grain model for service composition and make users and service composition agent work in different information granule level separately.A multi-grain formal model for service composition is proposed in this paper.This model considers the requirement of customers in service composition in the end-user view and we give a formal specification on mapping the web service description to the generalized decision logic language(GDL)for construction of multi-grain service composition view.GDL is a formal logic language proposed in granular computing research community as an expecting specification for definition of granular models.The proposed model is expected to provide

    This article presents the concept of "moments of high receptiveness" (MoHR or "Momentos de Alta Receptividad"), which is derived from the concept of "experiential coupling" ("Acoplamiento de Experiencias") proposed by Bleichmar (2001). Experiential coupling recently received empirical support by the work of Schiller and colleagues (2010). We will also show the conceptual placing of moments of high receptiveness with respect to the developments of Stern and colleagues (Stern and et al., 1998; Stern, 2004). In order to achieve both objectives, we focus on various clinical vignettes stressing the differences in repercussions of the technique. We describe use of stimuli for active evocation, explain how to identify moments of high receptiveness, and review ways to take advantage of these moments. Lastly, to minimize the risk of iatrogenic symptoms, we examine the role of therapists and some features of the therapeutic process when using this technique.

    Full Text Available Purpose. The article is aimed to figure out the features of Husserl's reception of anthropological Descartes rationalism. Its implementation requires a consistent solution of the following tasks: 1 schematically express a modern vision of the basic intentions of philosophizing as an anthropological rationalism; 2 highlight the main points of the Husserl's reception of Descartes’ rationalism as the deanthropologizing and analyze radicalization of its basic design as the reanthropologizing. Conclusions. When clarifying the question of the method of reception and completion of the philosophical Descartes’ project in the doctrine of Edmund Husserl, the author finds that the originality of his reception of anthropological Descartes’ rationalism appears as the paradoxical union of denying the existence of anthropology in the base project and the rediscovery of its key role in the radicalization of Descartes. Thinking of its way, he comes to the rediscovery some of the key ideas of the French philosopher, rooted in his anthropological rationalism. Among them is the basic intention of the ambivalence, the rejection of Descartes’ ideas of panrationalism, recognition irreducibility of philosophical method to the mathematical, constitutive of human presence in the new rationalism. Prospects for further research in understanding the author sees a meaningful relationship and continuity of the two great thinkers - namely, the personal nature of philosophizing and the ethical focus of their searching. Originality. Appeal to the reception of Husserl's Cartesian project confirms the thesis of an essential importance for the basic anthropological project of Descartes. The presented version of Husserl reception base project Descartes is a reproduction of the surface age stereotypes, which link the quest of the philosopher with the natural sciences and neglected anthropological measurements. The proposed version of the radicalization of Descartes’ project

    the demand-side of markets in the simplest possible way. This strategy has allowed a gradual increase in the sophistication of supply-side aspects of economic evolution, but the one-sided focus on supply is facing diminishing returns. Therefore, demand-side aspects of economic evolution have in recent years...... received increased attention. The present paper argues that the new emphasis on demand-side factors is quite crucial for a deepened understanding of economic evolution. The major reasons are the following: First, demand represents the core force of selection that gives direction to the evolutionary process....... Second, firms' innovative activities relate, directly or indirectly, to the structure of expected and actual demand. Third, the demand side represents the most obvious way of turning to the much-needed analysis of macro-evolutionary change of the economic system....

  4. [Early reception of Darwin's selection theory and its sequelae for comparative morphology today].

    Science.gov (United States)

    Rehkämper, G

    1997-01-01

    It is argued that Darwin's concept of evolutionary change is primarily based on the idea of functional adaptation. Genealogical aspects are seen as a secondary consequence of this hypothesis. Unfortunately, the reception of Darwin's work was concentrated on the genealogical aspects from the very beginning (Huxley, Haeckel) and thus channeled future development of evolutionary morphology in a very one-sided way. This direction of development led to the adoption of cladism as a very sophisticated concept of comparative morphology. Though cladism claims to contribute to our understanding of evolution, it is demonstrated that it suffers in this regard because of the incompatibility of "pure morphology" with the demands of functional thinking as an integrative part of Darwin's proposition.

    This article focuses on causality in demand. A methodology where causality is imposed and tested within an empirical co-integrated demand model, not prespecified, is suggested. The methodology allows different causality of different products within the same demand system. The methodology is applied...... to fish demand. On the German market for farmed trout and substitutes, it is found that supply sources, i.e. aquaculture and fishery, are not the only determinant of causality. Storing, tightness of management and aggregation level of integrated markets might also be important.

  14. Active vision and receptive field development in evolutionary robots.

    Floreano, Dario; Suzuki, Mototaka; Mattiussi, Dario

    2005-01-01

    In this paper, we describe the artificial evolution of adaptive neural controllers for an outdoor mobile robot equipped with a mobile camera. The robot can dynamically select the gazing direction by moving the body and/or the camera. The neural control system, which maps visual information to motor commands, is evolved online by means of a genetic algorithm, but the synaptic connections (receptive fields) from visual photoreceptors to internal neurons can also be modified by Hebbian plasticity while the robot moves in the environment. We show that robots evolved in physics-based simulations with Hebbian visual plasticity display more robust adaptive behavior when transferred to real outdoor environments as compared to robots evolved without visual plasticity. We also show that the formation of visual receptive fields is significantly and consistently affected by active vision as compared to the formation of receptive fields with grid sample images in the environment of the robot. Finally, we show that the interplay between active vision and receptive field formation amounts to the selection and exploitation of a small and constant subset of visual features available to the robot.

  15. Real gas effects on receptivity to kinetic fluctuations

    Tumin, Anatoli; Edwards, Luke

    2016-11-01

    Receptivity of high-speed boundary layers is considered within the framework of fluctuating hydrodynamics where stochastic forcing is introduced through fluctuating shear stress and heat flux stemming from kinetic fluctuations (thermal noise). The forcing generates unstable modes whose amplification downstream and may lead to transition. An example of high-enthalpy (16 . 53 MJ / kg) boundary layer at relatively low wall temperatures (Tw = 1000 K - 3000 K), free stream temperature (Te = 834 K), and low pressure (0 . 0433 atm) is considered. Dissociation at the chosen flow parameters is still insignificant. The stability and receptivity analyses are carried out using a solver for calorically perfect gas with effective Prandtl number and specific heats ratio. The receptivity phenomenon is unchanged by the inclusion of real gas effects in the mean flow profiles. This is attributed to the fact that the mechanism for receptivity to kinetic fluctuations is localized near the upper edge of the boundary layer. Amplitudes of the generated wave packets are larger downstream in the case including real gas effects. It was found that spectra in both cases include supersonic second Mack unstable modes despite the temperature ratio Tw /Te > 1 . Supported by AFOSR.

    Full Text Available This paper responds to the need of research on vocabulary knowledge in foreign language in secondary education in Spain. Thus, this research aims at investigating (i the receptive vocabulary knowledge of 49 girls and 43 boys, Spanish students learning English as a foreign language in a secondary school located in the north of Spain, and (ii its pedagogical implications for students’ understanding of written and spoken discourse in English (Adolphs & Schmitt 2004; Laufer 1992, 1997; Nation 2001. We used the 2,000 frequency band of the Vocabulary Level Test (VLT (Schmitt, Schmitt & Clapham, 2001, version 2 as the instrument to measure students’ receptive vocabulary knowledge. Our results reveal that the means of girls’ receptive vocabulary size is below 1,000 words, which agrees with the estimates proposed by López-Mezquita (2005 for Spanish students of the same age and educational level. On the contrary, the means for boys is slightly above 1,000 words, being the differences between boys’ and girls’ performance in the VLT statistically relevant. Our data also indicate that most of the students analysed in the present study could have problems to understand written and spoken discourse due to their low scores in the receptive vocabulary level test.

  5. Ovarian fluid of receptive females enhances sperm velocity

    Gasparini, Clelia; Andreatta, Gabriele; Pilastro, Andrea

    2012-05-01

    The females of several internal fertilizers are able to store sperm for a long time, reducing the risk of sperm limitation. However, it also means that males can attempt to mate outside females' receptive period, potentially increasing the level of sperm competition and exacerbating sexual conflict over mating. The guppy ( Poecilia reticulata), an internally fertilizing fish, is a model system of such competition and conflict. Female guppies accept courtship and mate consensually only during receptive periods of the ovarian cycle but receive approximately one (mostly forced) mating attempt per minute both during and outside their sexually receptive phase. In addition, females can store viable sperm for months. We expected that guppy females would disfavour sperm received during their unreceptive period, possibly by modulating the quality and/or quantity of the components present in the ovarian fluid (OF) over the breeding cycle. Ovarian fluid has been shown to affect sperm velocity, a determinant of sperm competition success in this and other fishes. We found that in vitro sperm velocity is slower in OF collected from unreceptive females than in OF from receptive females. Visual stimulation with a potential partner prior to collection did not significantly affect in vitro sperm velocity. These results suggest that sperm received by unreceptive females may be disfavoured as sperm velocity likely affects the migration process and the number of sperm that reach storage sites.

    Previous research over a period of six years has identified wastewater treatment facilities as good candidates for demand response (DR), automated demand response (Auto-­DR), and Energy Efficiency (EE) measures. This report summarizes that work, including the characteristics of wastewater treatment facilities, the nature of the wastewater stream, energy used and demand, as well as details of the wastewater treatment process. It also discusses control systems and automated demand response opportunities. Furthermore, this report summarizes the DR potential of three wastewater treatment facilities. In particular, Lawrence Berkeley National Laboratory (LBNL) has collected data at these facilities from control systems, submetered process equipment, utility electricity demand records, and governmental weather stations. The collected data were then used to generate a summary of wastewater power demand, factors affecting that demand, and demand response capabilities. These case studies show that facilities that have implemented energy efficiency measures and that have centralized control systems are well suited to shed or shift electrical loads in response to financial incentives, utility bill savings, and/or opportunities to enhance reliability of service. In summary, municipal wastewater treatment energy demand in California is large, and energy-­intensive equipment offers significant potential for automated demand response. In particular, large load reductions were achieved by targeting effluent pumps and centrifuges. One of the limiting factors to implementing demand response is the reaction of effluent turbidity to reduced aeration at an earlier stage of the process. Another limiting factor is that cogeneration capabilities of municipal facilities, including existing power purchase agreements and utility receptiveness to purchasing electricity from cogeneration facilities, limit a facility’s potential to participate in other DR activities.

    This study develops econometric models of residential demands for electricity, natural gas, and petroleum products. Fuel demands per household are estimated as functions of fuel prices, per capita income, heating degree days, and mean July temperature. Cross-sectional models are developed using a large data base containing observations for each state and year from 1951 through 1974. Long-run own-price elasticities for all three fuels are greater than unity with natural gas showing the greatest sensitivity to own-price changes. Cross-price elasticities are all less than unity except for the elasticity of demand for oil with respect to the price of gas (which is even larger than the own-price elasticity of demand for oil). The models show considerable stabiity with respect to own-price elasticities but much instability with respect to the cross-price and income elasticities.

    Objective To study the effect of single and low dose of RU486 on endometrial receptivity of healthy women. Methods A total of 5 healthy women were followed for one control and one treatment cycle. In the treatment cycle, a dose of 10 mg RU486 was administered on day luteinizing hormone (LH)-2. In both the control and treatment cycle, an endometrial biopsy was obtained on LH+7. These biopsies were assessed by immunohistochemical analysis to find the difference in expression of integrins and progesterone receptor (PR) between the control and treatment cycle. Results The treatment with RU486 increased the expression of α1 and α4 subunits of integrin in glandular epithelial cells, but did not influence β3 subunit. Moreover, the normal down-regulation of PR in epitherial cell nuclei was inhibited by 10 mg RU486. Conclusion Single dose of 10 mg RU486 impairs the establishment of endometrial receptivity on time.

Hence, given two groups of learners with the same hours of EFL instruction, the main objective of this research is to determine whether there exists any kind of interaction between the number of words learners know receptively and their motivation towards English as a Foreign Language (EFL. Most students in both groups were highly motivated. No relationship was identified between the receptive vocabulary knowledge and the general motivation for the secondary graders but a positive significant relationship was found for the primary CLIL graders. Several reasons will be adduced.

    Studies often report that bilingual participants possess a smaller vocabulary in the language of testing than monolinguals, especially in research with children. However, each study is based on a small sample so it is difficult to determine whether the vocabulary difference is due to sampling error. We report the results of an analysis of 1,738 children between 3 and 10 years old and demonstrate a consistent difference in receptive vocabulary between the two groups. Two preliminary analyses s...

    Full Text Available OBJECTIVE: To investigate the effects of receptive music therapy in clinical practice. METHODS: Receptive music therapy was individually applied via musical auditions, including five stages: musical stimulation, sensation, situation, reflection, and behavioral alteration. Following anamnesis and obtainment of consent, patients answered a first questionnaire on health risk evaluation (Q1, and after participating in 16 weekly music therapy sessions, answered a second one (Q2. RESULTS: Two men and 8 women, aged above 18 years, referred to us due to symptoms of stress, emotional suffering, and the need to change lifestyles (health risk behavior were studied between August 1998 and December 1999. Comparison between answers to Q1 and Q2, showed a trend (P=0.059 for reduction of ingestion of cholesterol-rich foods and for increased prospects in life with a tendency towards improvement, and also of increased intake of fiber-rich food (55.6%, increased levels of personal satisfaction (44.5%, and decreased levels of stress (66.7%. CONCLUSION: The study demonstrated decreased stress levels and increased personal satisfaction, higher consumption of fiber-rich food, lower cholesterol intake, and a better perspective on life, suggesting that receptive music therapy may be applied in clinical practice as an auxiliary therapeutic intervention for the treatment of behavioral health risks.

    To characterize the performance of students from the 5th year of primary school, with and without indicatives of reading and writing disorders, in receptive vocabulary and reading comprehension of sentences and texts, and to verify possible correlations between both. This study was approved by the Research Ethics Committee of the institution (no. 098/13). Fifty-two students in the 5th year from primary school, with and without indicatives of reading and writing disorders, and from two public schools participated in this study. After signing the informed consent and having a speech therapy assessment for the application of inclusion criteria, the students were submitted to a specific test for standardized evaluation of receptive vocabulary and reading comprehension. The data were studied using statistical analysis through the Kruskal-Wallis test, analysis of variance techniques, and Spearman's rank correlation coefficient with level of significance to be 0.05. A receiver operating characteristic (ROC) curve (was constructed in which reading comprehension was considered as gold standard. The students without indicatives of reading and writing disorders presented a better performance in all tests. No significant correlation was found between the tests that evaluated reading comprehension in either group. A correlation was found between reading comprehension of texts and receptive vocabulary in the group without indicatives. In the absence of indicatives of reading and writing disorders, the presence of a good range of vocabulary highly contributes to a proficient reading comprehension of texts.

The aim of this study was to systematically test both the melodic and rhythmic domains of music perception and expression in left- and right-sided stroke patients compared to healthy subjects. Music perception was assessed using rhythmic and melodic discrimination tasks, while tests of expressive function involved the vocal or instrumental reproduction of rhythms and melodies. Our approach revealed deficits in receptive and expressive functions in stroke patients, mediated by musical expertise. Those patients who had experienced a short period of musical training in childhood and adolescence performed better in the receptive and expressive subtests compared to those without any previous musical training. While discrimination of specific musical patterns was unimpaired after a right-sided stroke, patients with a left-sided stroke had worse results for fine melodic and rhythmic analysis. In terms of expressive testing, the most consistent results were obtained from a test that required patients to reproduce sung melodies. This implies that the means of investigating production abilities can impact the identification of deficits.

    To compare the comprehension of depressed and non-depressed male and female Iranian learners of English as a Foreign Language (EFL) in receptive skills, and to investigate whether inefficiency in learning English could be due to depression. We selected 126 boys and 96 girls aged between 15 and 18 by simple random sampling from 2 high schools in Kerman, Iran to examine whether there was any significant relationship between depression and comprehension of receptive skills in males and females. We undertook this descriptive, correlational study between January and May 2011 in Kerman, Iran. After administration of the Beck Depression Inventory (BDI), we found that 93 students were non-depressed, 65 had minimal depression, 48 mild depression, and 16 suffered from severe depression. The correlation between participants` scores on listening and reading test with depression level indicated a significant relationship between depression and comprehension of both listening, and reading. Males had higher scores in both reading and listening. In listening, there was no significant difference among the levels of depression and males and females. Regarding the reading skill, there was no significant difference among levels of depression; however, the reading comprehension of males and females differed significantly. Learners who show a deficiency in receptive skills should be examined for the possibility of suffering from some degree of depression.

    Drosophila melanogaster females respond to male courtship by either rejecting the male or allowing copulation. The neural mechanisms underlying these female behaviors likely involve the integration of sensory information in the brain. Because doublesex (dsx) controls other aspects of female differentiation, we asked whether dsx-expressing neurons mediate virgin female receptivity to courting males. Using intersectional techniques to manipulate the activities of defined subsets of dsx-expressing neurons, we found that activation of neurons in either the pCd or pC1 clusters promotes receptivity, while silencing these neurons makes females unreceptive. Furthermore, pCd and pC1 neurons physiologically respond to the male-specific pheromone cis-vaccenyl acetate (cVA), while pC1 neurons also respond to male courtship song. The pCd and pC1 neurons expressing dsx in females do not express transcripts from the fruitless (fru) P1 promoter. Thus, virgin female receptivity is controlled at least in part by neurons that are distinct from those governing male courtship.

    Full Text Available K-pop’s popularity and its participatory fan culture have expanded beyond Asia and become significant in Europe in the past few years. After South Korean pop singer Psy’s “Gangnam Style” music video topped the Austrian chart in October 2012, the number and size of K-pop events in Austria sharply increased, with fans organizing various participatory events, including K-pop auditions, dance festivals, club meetings, quiz competitions, dance workshops, and smaller fan-culture gatherings. In the private sector, longtime fans have transitioned from participants to providers, and in the public sector, from observers to sponsors. Through in-depth interviews with event organizers, sponsors, and fans, this article offers an ethnographic study of the reception of K-pop in Europe that takes into consideration local interactions between fans and Korean sponsors, perspectives on the genre, patterns of social integration, and histories. As a case study, this research stresses the local situatedness of K-pop fan culture by arguing that local private and public sponsors and fans make the reception of K-pop different in each locality. By exploring local scenes of K-pop reception and fan culture, the article demonstrates the rapidly growing consumption of K-pop among Europeans and stresses multidirectional understandings of globalization.

    1995-04-01

    One of the natural methods of tactual communication in common use among individuals who are both deaf and blind is the tactual reception of sign language. In this method, the receiver (who is deaf-blind) places a hand (or hands) on the dominant (or both) hand(s) of the signer in order to receive, through the tactual sense, the various formational properties associated with signs. In the study reported here, 10 experienced deaf-blind users of either American Sign Language (ASL) or Pidgin Sign English (PSE) participated in experiments to determine their ability to receive signed materials including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87% correct. The most frequent type of error made in identifying isolated signs was related to misperception of individual phonological components of signs. For presentation of signed sentences (translations of the English CID sentences into ASL or PSE), the performance of individual subjects ranged from 60-85% correct reception of key signs. Performance on sentences was relatively independent of rate of presentation in signs/sec, which covered a range of roughly 1 to 3 signs/sec. Sentence errors were accounted for primarily by deletions and phonological and semantic/syntactic substitutions. Experimental results are discussed in terms of differences in performance for isolated signs and sentences, differences in error patterns for the ASL and PSE groups, and communication rates relative to visual reception of sign language and other natural methods of tactual communication.

    In recent years, demand side management (DSM) has emerged as an efficient utility planning strategy for reducing capacity shortages and improving system load factors. The Indian government is adopting various policies to implement DSM programs. DSM implementation involves a variety of interests with conflicting objectives, and a range of possible implementation strategies with varying implications for effectiveness, cost, feasibility, efficiency and stakeholder acceptance. This necessitates a critical comparison of the strategies to determine a preferred strategy or combination of strategies from each specific stakeholder's point of view. The present study evaluates DSM implementation strategies from a multiobjective perspective using the Analytic Hierarchy Process (AHP). Eight strategies and six criteria were considered. Forty utility, regulator, and consumer stakeholders were surveyed. The most highly ranked strategies involved creating dedicated funds and providing technical support to end users for effective implementation of DSM. (author)

    Institutions all over the world are continuously exploring ways to use ICT in improving teaching and learning effectiveness. The use of course web pages, discussion groups, bulletin boards, and e-mails have shown considerable impact on teaching and learning in significant ways, across all disciplines. ELearning has emerged as an alternative to traditional classroom-based education and training and web lectures can be a powerful addition to traditional lectures. They can even serve as a main content source for learning, provided users can quickly navigate and locate relevant pages in a web lecture. A web lecture consists of video and audio of the presenter and slides complemented with screen capturing. In this paper, an automated approach for recording live lectures and for browsing available web lectures for on-demand applications by end users is presented.

  16. Flexible Demand Management under Time-Varying Prices

    Science.gov (United States)

    Liang, Yong

    In this dissertation, the problem of flexible demand management under time-varying prices is studied. This generic problem has many applications, which usually have multiple periods in which decisions on satisfying demand need to be made, and prices in these periods are time-varying. Examples of such applications include multi-period procurement problem, operating room scheduling, and user-end demand scheduling in the Smart Grid, where the last application is used as the main motivating story throughout the dissertation. The current grid is experiencing an upgrade with lots of new designs. What is of particular interest is the idea of passing time-varying prices that reflect electricity market conditions to end users as incentives for load shifting. One key component, consequently, is the demand management system at the user-end. The objective of the system is to find the optimal trade-off between cost saving and discomfort increment resulted from load shifting. In this dissertation, we approach this problem from the following aspects: (1) construct a generic model, solve for Pareto optimal solutions, and analyze the robust solution that optimizes the worst-case payoffs, (2) extend to a distribution-free model for multiple types of demand (appliances), for which an approximate dynamic programming (ADP) approach is developed, and (3) design other efficient algorithms for practical purposes of the flexible demand management system. We first construct a novel multi-objective flexible demand management model, in which there are a finite number of periods with time-varying prices, and demand arrives in each period. In each period, the decision maker chooses to either satisfy or defer outstanding demand to minimize costs and discomfort over a certain number of periods. We consider both the deterministic model, models with stochastic demand or prices, and when only partial information about the stochastic demand or prices is known. We first analyze the stochastic

Veterans and their family, as well as the whole civic community, are the addressees of their work. What follows is a detailed analysis of those works with the intention both to determine whether they can be classified as work of reception – which, so far, has never been proposed – and to discuss the plausibility of this kind of reception, which also turns into social outreach, and how it can be proposed without risking to completely dismiss changes that have occurred in the vision of war, although we may agree that the sufferings of war did not change too much1. Like in the first part, the discussion will be also carried on within a pedagogical discourse. A personal note based on a personal experience will conclude the analysis.

    Nordel has seen demand side flexibility and demand response (DR) to high prices as a necessity for the Nordic market model functioning. The importance of demand response is increasing while the power balance is tightening. Therefore, measures activating demand response have a high priority. In the report 'Peak Production Capability and Peak Load in the Nordic Electricity Market' (Summary and conclusions and Appendix 1) Nordel recommended that each TSO shall make an action plan for enhancing demand response and together with the other stakeholders develop procedures for systematic monitoring of demand response. The practical potential in the medium term was roughly estimated in the above mentioned Nordel report to about 12 000 MW in total. Every 10 % of the potential that can be activated (1 200 MW) equals about 2 % of the peak load in the Nordic countries. This report summarizes the action plans and measures taken by the TSOs so far. In addition, other joint activities going on within Nordel as regards demand response and its systematic monitoring are summarized. In this context, measures aiming at more efficient utilisation of the local back-up generation are also included. By definition back-up generation is not a demand resource, but it is often discussed in the same context, because it is a resource that is dispersed located and controlled by the end-users. Increased local generation reduces need for transmission or distribution of power. For the activation of the back-up generation similar procedures are needed as to DR resources. (au)

    Full Text Available Studying the consumer’s behavior by the ordinal approach of utility with the help of indifference curves allows us to deduce the two “movement laws of demand” in this chapter: the demand for a “normal” good is decreasing function of its price and an increasing function of income. We will use the elasticity concept to measure the intensity of the relation that is established between the demand, on the one hand, and prices or income, on the other hand: elasticity – price, direct and crossed, and elasticity – income. We can classify the goods in many categories, depending on the values that this elasticity takes. The demand elasticity can be determined depending on price and income. It reflects the proportion in which the demand for different products changes with the modification of the consumers’ income, the other factors remaining constant. The elasticity compared to the income is a demonstration of legality from the consumer’s sphere, which determines a certain hierarchy of the needs of each population category in a certain level of income. The movement of prices orients both the options and decisions of producers, namely the most useful productions and the most efficient investments, as well as the consumers’ options and decisions on the most advantageous buying of goods and services that they need. The prices appear as a “signal system” coordinating and making coherence the economic agents’ decisions – producers, consumers and population.

Twenty primiparous does maintained without reproduction were tested over 4 mo (3 tests per week at a 2- or 3-day interval after their first kindling. Out of 48 tests, the receptivity rate was 52.5±50.0% on average and varied from 20.0 to 73.3% depending on the test day. The does were lactating at the beginning of the test period and a strong receptivity decrease was revealed at the peak of lactation. Receptivity did not vary according to the tester buck or to the test operator. The individual receptivity of does varied from 8.6 to 81.3%; three of them had a receptivity rate lower than 30% and four of them a receptivity rate greater than 70%. No relationship was revealed between average receptivity and body weight or body weight variations around first litter weaning. The repeatability of sexual receptivity of non-lactating does was 23.2%. Lowly receptive does had a shorter average oestrus time (<2 tests and a longer dioestrus time (≥6 tests, whereas highly receptive does had a longer oestrus time (>4 tests and a shorter dioestrus time (≤3 tests. The correlation between average receptivity and average oestrus time was 0.80. These results indicate a fairly high individual variability of the expression of rabbit sexual receptivity and of its duration, and justify the exploration of an eventual genetic origin in a subsequent experiment.

  4. Demand surge following earthquakes

    Science.gov (United States)

    Olsen, Anna H.

    2012-01-01

    Demand surge is understood to be a socio-economic phenomenon where repair costs for the same damage are higher after large- versus small-scale natural disasters. It has reportedly increased monetary losses by 20 to 50%. In previous work, a model for the increased costs of reconstruction labor and materials was developed for hurricanes in the Southeast United States. The model showed that labor cost increases, rather than the material component, drove the total repair cost increases, and this finding could be extended to earthquakes. A study of past large-scale disasters suggested that there may be additional explanations for demand surge. Two such explanations specific to earthquakes are the exclusion of insurance coverage for earthquake damage and possible concurrent causation of damage from an earthquake followed by fire or tsunami. Additional research into these aspects might provide a better explanation for increased monetary losses after large- vs. small-scale earthquakes.

  5. Membrane–initiated estradiol signaling regulating sexual receptivity

    Full Text Available Estradiol has profound actions on the structure and function of the nervous system. In addition to nuclear actions that directly modulate gene expression, the idea that estradiol can rapidly activate cell signaling by binding to membrane estrogen receptors (mERs has emerged. Even the regulation of sexual receptivity, an action previously thought to be completely regulated by nuclear ERs, has been shown to have a membrane-initiated estradiol signaling (MIES component. This highlighted the question of the nature of mERs. Several candidates have been proposed, ERα, ERβ, ER-X, GPR30 (G protein coupled estrogen receptor; GPER, and a receptor activated by a diphenylacrylamide compound, STX. Although each of these receptors has been shown to be active in specific assays, we present evidence for and against their participation in sexual receptivity by acting in the lordosis-regulating circuit. The initial MIES that activates the circuit is in the arcuate nucleus of the hypothalamus (ARH. Using both activation of μ-opioid receptors (MOR in the medial preoptic nucleus and lordosis behavior, we document that both ERα and the STX receptor participate in the required MIES. ERα and the STX receptor activation of cell signaling are dependent on the transactivation of type 1 metabotropic glutamate receptors (mGluR1a that augment progesterone synthesis in astrocytes and protein kinase C (PKC in ARH neurons. While estradiol-induced sexual receptivity does not depend on neuroprogesterone, proceptive behaviors do. Moreover, the ERα and the STX receptor activation of medial preoptic MORs and augmentation of lordosis were sensitive to mGluR1a blockade. These observations suggest a common mechanism through which mERs are coupled to intracellular signaling cascades, not just in regulating reproduction, but in actions throughout the neuraxis including the cortex, hippocampus, striatum and DRGs.

  6. Cortico-Cortical Receptive Field Estimates in Human Visual Cortex

    Full Text Available Human visual cortex comprises many visual areas that contain a map of the visual field (Wandell et al 2007, Neuron 56, 366–383. These visual field maps can be identified readily in individual subjects with functional magnetic resonance imaging (fMRI during experimental sessions that last less than an hour (Wandell and Winawer 2011, Vis Res 718–737. Hence, visual field mapping with fMRI has been, and still is, a heavily used technique to examine the organisation of both normal and abnormal human visual cortex (Haak et al 2011, ACNR, 11(3, 20–21. However, visual field mapping cannot reveal every aspect of human visual cortex organisation. For example, the information processed within a visual field map arrives from somewhere and is sent to somewhere, and visual field mapping does not derive these input/output relationships. Here, we describe a new, model-based analysis for estimating the dependence between signals in distinct cortical regions using functional magnetic resonance imaging (fMRI data. Just as a stimulus-referred receptive field predicts the neural response as a function of the stimulus contrast, the neural-referred receptive field predicts the neural response as a function of responses elsewhere in the nervous system. When applied to two cortical regions, this function can be called the cortico-cortical receptive field (CCRF. We model the CCRF as a Gaussian-weighted region on the cortical surface and apply the model to data from both stimulus-driven and resting-state experimental conditions in visual cortex.

  7. Demand scenarios, worldwide

    Existing methods are inadequate for developing aggregate (regional and global) and long-term (several decades) passenger transport demand scenarios, since they are mainly based on simple extensions of current patterns rather than causal relationships that account for the competition among transport modes (aircraft, automobiles, buses and trains) to provide transport services. The demand scenario presented in this paper is based on two empirically proven invariances of human behavior. First, transport accounts for 10 to 15 percent of household total expenditures for those owning an automobile, and around 5 percent for non-motorized households on average (travel money budget). Second, the mean time spent traveling is approximately one hour per capita per day (travel time budget). These two budgets constraints determine the dynamics of the scenario: rising income increases per capita expenditure on travel which, in turn, increase demand for mobility. Limited travel time constraints travelers to shift to faster transport systems. The scenario is initiated with the first integrated historical data set on traffic volume in 11 world regions and the globe from 1960 to 1990 for all major modes of motorized transport. World average per capita traffic volume, which was 1,800 kilometers in 1960 and 4,2090 in 1990, is estimated to rise to 7,900 kilometers in 2020 - given a modest average increase in Gross World Product of 1.9% per year. Higher economic growth rates in Asian regions result in an increase in regional per capita traffic volume up to a factor of 5.3 from 1990 levels. Modal splits continue shifting to more flexible and faster modes of transport. At one point, passenger cars can no longer satisfy the increasing demand for speed (i.e. rising mobility within a fixed time budget). In North America it is estimated that the absolute traffic volume of automobiles will gradually decline starting in the 2010s. (author) 13 figs., 6 tabs., 35 refs.

  10. Automated Demand Response Approaches to Household Energy Management in a Smart Grid Environment

    Science.gov (United States)

    Adika, Christopher Otieno

    The advancement of renewable energy technologies and the deregulation of the electricity market have seen the emergence of Demand response (DR) programs. Demand response is a cost-effective load management strategy which enables the electricity suppliers to maintain the integrity of the power grid during high peak periods, when the customers' electrical load is high. DR programs are designed to influence electricity users to alter their normal consumption patterns by offering them financial incentives. A well designed incentive-based DR scheme that offer competitive electricity pricing structure can result in numerous benefits to all the players in the electricity market. Lower power consumption during peak periods will significantly enhance the robustness of constrained networks by reducing the level of power of generation and transmission infrastructure needed to provide electric service. Therefore, this will ease the pressure of building new power networks as we avoiding costly energy procurements thereby translating into huge financial savings for the power suppliers. Peak load reduction will also reduce the inconveniences suffered by end users as a result of brownouts or blackouts. Demand response will also drastically lower the price peaks associated with wholesale markets. This will in turn reduce the electricity costs and risks for all the players in the energy market. Additionally, DR is environmentally friendly since it enhances the flexibility of the power grid through accommodation of renewable energy resources. Despite its many benefits, DR has not been embraced by most electricity networks. This can be attributed to the fact that the existing programs do not provide enough incentives to the end users and, therefore, most electricity users are not willing to participate in them. To overcome these challenges, most utilities are coming up with innovative strategies that will be more attractive to their customers. Thus, this dissertation presents various

    Studies often report that bilingual participants possess a smaller vocabulary in the language of testing than monolinguals, especially in research with children. However, each study is based on a small sample so it is difficult to determine whether the vocabulary difference is due to sampling error. We report the results of an analysis of 1,738 children between 3 and 10 years old and demonstrate a consistent difference in receptive vocabulary between the two groups. Two preliminary analyses suggest that this difference does not change with different language pairs and is largely confined to words relevant to a home context rather than a school context.

    In certain cases, noises can improve signal transmission or signal processing. This phenomenon is the so-called stochastic resonance. In this paper, we firstly present two theorems to prove that the noisy threshold neuron shows stochastic resonance in terms of the probability of correct reception. Secondly, we analytically discuss stochastic resonance effects and give the probability-optimal noise levels for four representative noises. Finally, we discuss the stochastic gradient ascent learning law, which can be used to find the probability-optimal noise levels. We also present our simulation results for the four representative noises. These results indicate that stochastic resonance is favorable both in biological neurons and in signal processing.

    The first direct exposure to lunar material for Crew Reception personnel probably happened late Friday, July 25, 1969. Terry Slezak (displaying moon dust on his left hand fingers), Manned Spacecraft Center (MSC) photographic technician, was removing film magazines from the first of two containers when the incident occurred. As he removed the plastic seal from Magazine S, one of the 70mm magazines taken during Apollo 11 Extravehicular Activity (EVA), it was apparent that the exterior of the cassette displayed traces of a black powdery substance. Apollo 11 Commander Neil Armstrong reported during the mission that he had retrieved a 70mm cassette which had dropped to the lunar surface.

    Evidence suggests that children present with receptive language skills that are equivalent to or more advanced than expressive language skills. This profile holds true for typical and delayed language development. This study aimed to determine if such a profile existed for preschool children from an area of social deprivation and to investigate if particular language skills influence any differences found between expressive and receptive skills. Data from 187 CELF P2 UK assessments conducted on preschool children from two socially disadvantaged areas in a city in southern Ireland. A significant difference was found between Receptive Language Index (RLI) and Expressive Language Index (ELI) scores with Receptive scores found to be lower than Expressive scores. The majority (78.6%) of participants had a lower Receptive Language than Expressive score (RLI ELI), with very few (3.2%) having the same Receptive and Expressive scores (RLI = ELI). Scores for the Concepts and Following Directions (receptive) sub-test were significantly lower than for the other receptive sub tests, while scores for the Expressive Vocabulary sub-test were significantly higher than for the other expressive sub tests. The finding of more advanced expressive than receptive language skills in socially deprived preschool children is previously unreported and clinically relevant for speech-language pathologists in identifying the needs of this population.

    Objective To establish the mice model of implantation dysfunction and to study the endometrial receptivity during implantation in implantation dysfunction mouse. Methods Sexually mature female virgin, Kunming mice were randomly assigned to the control group and the model group postcoitally. The model mice at 9 : 00 AM on d 4 of pregnancy(d 4) were injected subcutaneously with mifepristone. All animals were sacrificed at 9:00 PM on d 4 and their uterine horns were examined for the presence of implanted embryos. Histopathology of uterine endometrium was observed by light-microscope. The endometrial expressions of estrogen receptor (ER) and progesterone receptor (PR) assessed by immunnohistochemical SP method. The endometrial expressions of ER mRNA and PR mRNA were assessed by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).Results Compared with control group, implantation rates and average embryo number significently decreased in model group, the development of endometrium was inhibited. In model group, absorbency and area rate of ER and PR in the gland and stroma were lower than those in control group (P<0.05). Expressions of ER mRNA and PR mRNA in model uterus were significantly lower than those in the control.Conclusion The endometrial receptivity and implantation decreased in mifepristoneinduced implantation dysfunction mouse.

    2005-01-01

    Summary: In order To evaluate whether the parameters of spiral artery blood flow, as measured by transvaginal color Doppler, may be used to assess endometrium receptivity prior to embryo transfer (ET), a retrospective study of 94 infertile women who had undergone ART treatments with different outcomes (pregnant or nonpregnant) was done. Subendometrial blood flow was evaluated. The resistance index (RI), systolic/diastolic ratio (S/D) and pulsatility index (PI) were significantly lower in those who achieved pregnancy as compared with those who did not: 0.62±0.04 vs 0.68±0.04 (P<0.001), 2.66±0.33 vs 3.19±0.39 (P<0.01) and 1.15±0.17 vs 1.34±0.22 (P<0.05), respectively. Furthermore, when RI>0.72, PI>1.6, and S/D>3.6, no pregnancy occurred. These data suggest that the parameters of spiral artery blood flow could be used as a new assay in predicting endometrial receptivity before ET.

    Embryo implantation remains a significant challenge for assisted reproductive technology, with implantation failure occurring in ∼50% of in vitro fertilization attempts. Understanding the molecular mechanisms underlying uterine receptivity will enable the development of new interventions and biomarkers. TGFβ family signaling in the uterus is critical for establishing and maintaining pregnancy. Follistatin (FST) regulates TGFβ family signaling by selectively binding TGFβ family ligands and sequestering them. In humans, FST is up-regulated in the decidua during early pregnancy, and women with recurrent miscarriage have lower endometrial expression of FST during the luteal phase. Because global knockout of Fst is perinatal lethal in mice, we generated a conditional knockout (cKO) of Fst in the uterus using progesterone receptor-cre to study the roles of uterine Fst during pregnancy. Uterine Fst-cKO mice demonstrate severe fertility defects and deliver only 2% of the number of pups delivered by control females. In Fst-cKO mice, the uterine luminal epithelium does not respond properly to estrogen and progesterone signals and remains unreceptive to embryo attachment by continuing to proliferate and failing to differentiate. The uterine stroma of Fst-cKO mice also responds poorly to artificial decidualization, with lower levels of proliferation and differentiation. In the absence of uterine FST, activin B expression and signaling are up-regulated, and bone morphogenetic protein (BMP) signals are impaired. Our findings support a model in which repression of activin signaling by FST enables uterine receptivity by preserving critical BMP signaling.

  1. Go contributes to olfactory reception in Drosophila melanogaster

    Directory of Open Access Journals (Sweden)

    Roman Gregg

    2009-01-01

    Full Text Available Abstract Background Seven-transmembrane receptors typically mediate olfactory signal transduction by coupling to G-proteins. Although insect odorant receptors have seven transmembrane domains like G-protein coupled receptors, they have an inverted membrane topology and function as ligand-gated cation channels. Consequently, the involvement of cyclic nucleotides and G proteins in insect odor reception is controversial. Since the heterotrimeric Goα subunit is expressed in Drosophila olfactory receptor neurons, we reasoned that Go acts together with insect odorant receptor cation channels to mediate odor-induced physiological responses. Results To test whether Go dependent signaling is involved in mediating olfactory responses in Drosophila, we analyzed electroantennogram and single-sensillum recording from flies that conditionally express pertussis toxin, a specific inhibitor of Go in Drosophila. Pertussis toxin expression in olfactory receptor neurons reversibly reduced the amplitude and hastened the termination of electroantennogram responses induced by ethyl acetate. The frequency of odor-induced spike firing from individual sensory neurons was also reduced by pertussis toxin. These results demonstrate that Go signaling is involved in increasing sensitivity of olfactory physiology in Drosophila. The effect of pertussis toxin was independent of odorant identity and intensity, indicating a generalized involvement of Go in olfactory reception. Conclusion These results demonstrate that Go is required for maximal physiological responses to multiple odorants in Drosophila, and suggest that OR channel function and G-protein signaling are required for optimal physiological responses to odors.

  2. Meeting increased demand.

    New Zealand is a little country with a little economy but with a population that's rapidly aging. New Zealand's population is only 4.3 million people. It's GDP is only $US58.6 billion (2002). New Zealand's expenditure on health as a percentage of GDP is not out of line with that of other countries. As a nation we have been increasing expenditure on health over recent years. In 1990 we spent 7% of GDP on health. In 1995 that increased to 7.65% and is now 8.3%. However, in per capita terms our expenditure on health does not compare so well with like countries. The size of New Zealand's economy is restricting what our country spends on health. Health is already the second highest demand on the New Zealand tax dollar. The tolerance of New Zealanders would be challenged if a Government attempted to increase taxes further to meet the growing demands for expenditure on health, but at the same time the population's expectations are increasing. This is the challenging situation we face today. What lies ahead? Like all industrialized countries New Zealand is facing an aging population. The population below age 40 is decreasing, but it is increasing significantly over that age. 16% of the population is currently aged over 60. By 2051 this proportion will almost double to just over 31%. Coupled with the aging population is increased awareness and expectations, as access to options for treatment and technology becomes readily accessible to the population through such media as the internet. The extent of the impact of the aging population can be clearly represented by focusing on one specialty such as orthopaedics. The New Zealand Orthopaecic Association undertook a study in July 2003 which concluded (among other things) that as a result of the projected aging of the population, over the next 50 years: Musculo-skeletal operations will increase by over 30%. The number of hip replacements will nearly double. The incidence of osteoporosis will increase by a massive 201%. The number

    2013-03-01

    The current study builds on the emerging autism spectrum disorder (ASD) literature that associates autonomic nervous system activity with social function, and examines the link between respiratory sinus arrhythmia (RSA) and both social behavior and cognitive function. The RSA response pattern was assessed in 23 4- to 7-year-old children diagnosed with an ASD. Higher baseline RSA amplitudes were associated with better social behavior (i.e., more conventional gestures, more instances of joint attention) and receptive language abilities. Similar to reports of typically developing children, ASD children with higher RSA amplitude at baseline showed greater RSA and HP reactivity during an attention-demanding task. These results highlight the importance of studying RSA as a marker of positive function in children with ASD.

  4. On Movie Title Translation from the Perspective of Reception Aesthetics

    Movie is a popular art which occupies an important position in people’s leisure time. Movie title, as the most direct and accessible tool for audience to know about the movie, is very significant to attract audience into the cinema. Therefore, the translation of movie title cannot be ignored. However, due to the cultural differences in Chinese and English culture, the problem of movie title translation is obvious which needs to be paid attention to the translation and people working in movie industry. Traditional translation theory puts more emphasis on the important and authoritative status of original text and author. But this notion cannot satisfy the needs of movie title translation to the largest extent. Movie is not only a cultural and linguistic product, it also is a special commercial product. The ultimate objective of movie is to allure the audience into the cinema to watch and ap-preciate it in addition to provide the cultural information. Reception aesthetics, as a theory of literary criticism, gives priority to readers’role in literary understanding and interpretation. According to reception aesthetics, the horizon of expectation should be taken into consideration when the translation work begins to be done. Horizon of expectation is composed of the readers’or au-diences’ previous cultural norms, assumptions, and criteria in the source language and culture at a given time. Movie title, as a special text, is also understood and influenced by the audience’s horizon of expectation. Chinese audience, before they decide to watch a movie, are naturally harbor their horizon of expectation about the movie. They will form their judgment and assumptions about the genre, plot, story, background about the movie from the movie title. These kind of horizon of expectation will conse-quently influence their ultimate decision to watch the movie or not. Hence, in doing the movie title translation, the translator is supposed to keep the audience’s horizon of

  8. Physical demands in worklife.

    Science.gov (United States)

    Astrand, I

    1988-01-01

    Industrial occupations which are physically strenuous in the traditional sense of the word have decreased in number. They have partly been replaced by "light," repetitive, monotonous work tasks performed in a sitting position. The number of heavy work tasks within the service sector has increased. Specialization has been intensified. The individual's capacity for strenuous work is still of importance to successful work performance. Many studies show that an optional choice of work pace in physically demanding occupational work results in an adaptation of pace or intensity until the worker is utilizing 40-50% of her or his capacity. When the work rate is constrained, the relative strain of the individual varies inversely with the physical work capacity. The frequency of musculoskeletal disorders has concurrently increased with the implementation of industrial mechanization. New, wise, ergonomic moves are needed to stop this development.

    1992-04-01

    Ego receptivity has been described as important for the psychotherapy process and as a characteristic of hypnosis (Deikman, 1974: Dosamantes-Alperson, 1979; Fromm, 1979). Receptivity also has been associated with a measure of absorption (Tellegen, 1981). In the first pilot study with 6 dance/movement therapy students, higher observer ratings of receptivity were associated with greater hypnotizability (r = .79, df = 4, p less than .05, 2-tailed test). In the second pilot study, the correlation was replicated (r = .51, df = 12, p = .06, 2-tailed test) with 14 dance/movement therapy students. In the second pilot study, receptivity did not correlate with absorption. Receptivity and absorption, however, accounted for 54% of hypnotizability population variance in a step-wise multiple regression. Receptivity accounted for a unique part of the variance after the effects of absorption were removed. It was concluded that receptivity should be explored as a potential predictor of hypnotizability, and that a reliable scaled measure of receptivity should be developed.

    1999-12-01

    Thailand has a critical need for effective long-term energy planning because of the country's rapidly increasing energy consumption. In this study, the demand for electricity by the residential sector is modeled using a framework that provides detailed estimates of the timing and spatial distribution of changes in energy demand. A population model was developed based on the Cohort-Component method to provide estimates of population by age, sex and urban/non-urban residency in each province. A residential electricity end user model was developed to estimate future electricity usage in urban and non-urban households of the seventy-six provinces in Thailand during the period 1999--2019. Key variables in this model include population, the number of households, family household size, and characteristics of eleven types of electric household appliance such as usage intensity, input power, and saturation rate. The methodology employed in this study is a trending method which utilizes expert opinion to estimate future variables based on a percentage change from the most current value. This study shows that from 1994 to 2019 Thailand will experience an increase in population from 55.4 to 83.6 million. Large percentage population increases will take place in Bangkok, Nonthaburi, Samut Prakarn, Nakhon Pathom and Chonburi. At a national level, the residential electricity consumption will increase from approximately 19,000 to 8 1,000 GWh annually. Consumption in non-urban households will be larger than in urban households, with respective annual increases of 8.0% and 6.2% in 2019. The percent increase of the average annual electricity consumption will be four times the average annual percent population increase. Increased electricity demand is largely a function of increased population and increased demand for high-energy appliances such as air conditioners. In 1994, air conditioning was responsible for xx% of total residential electricity demand. This study estimates that in

  4. Emotional engagement during literary reception: do men and women differ?

    2013-01-01

    This contribution examines the emotional engagement of men and women when reading narrative texts, aiming to see under which textual conditions men and women turn out to be different from or similar to each other in what they think and feel during reception. As part of an experimental mixed-methods study, male and female readers are asked to read either experience-type texts (focusing on inner experiences of characters) or action-type texts (focusing on actions as part of a suspenseful plot) and report their engagement on questionnaire scales and in written protocols. Results show that men and women differ in their engagement when reading action texts and in their emotional affinity to plots. They are highly similar when reading the experience texts, however, and in their affinity to characters. This study underlines that the emotional responses of males and females during reading are highly dependent on (con)textual cues.

    2015-01-01

    Male moths detect and find their mates using species-specific sex pheromones emitted by conspecific females. Olfaction plays a vital role in this behavior. Since the first discovery of an insect sex pheromone from the silkmoth Bombyx mori, great efforts have been spent on understanding the sensing of the pheromones in vivo. Much progress has been made in elucidating the molecular mechanisms that mediate chemoreception in insects in the past few decades. In this review, we focus on pheromone reception and detection in moths, from the molecular to the behavioral level. We trace the information pathway from the capture of pheromone by male antennae, binding and transportation to olfactory receptor neurons, receptor activation, signal transduction, molecule inactivation, through brain processing and behavioral response. We highlight the impact of recent studies and also provide our insights into pheromone processing.

    Full Text Available We first show some successes of discrete mathematical chemistry (DMC, a branch of theoretical chemistry born in the 1960s and 1970s. Then we explore the social context in which the emergence of DMC took place, initiated mainly in East European countries. The availability of knowledge, especially of mathematical knowledge, and the lack of research funds were the main conditions that helped get DMC started. We also explore the reception of DMC in the chemical and mathematical circles, being flat rejection in chemistry and slow acceptance in mathematics. Finally, we discuss some definitions of the subject and propose a new one stating that mathematical chemistry is the realization of mathematical thinking in chemistry, understood as functional thinking defined by Felix Klein in the Erlangen Program.

  7. Optimum spatiotemporal receptive fields for vision in dim light.

    2009-04-22

    Many nocturnal insects depend on vision for daily life and have evolved different strategies to improve their visual capabilities in dim light. Neural summation of visual signals is one strategy to improve visual performance, and this is likely to be especially important for insects with apposition compound eyes. Here we develop a model to determine the optimum spatiotemporal sampling of natural scenes at gradually decreasing light levels. Image anisotropy has a strong influence on the receptive field properties predicted to be optimal at low light intensities. Spatial summation between visual channels is predicted to extend more strongly in the direction with higher correlations between the input signals. Increased spatiotemporal summation increases signal-to-noise ratio at low frequencies but sacrifices signal-to-noise ratio at higher frequencies. These results, while obtained from a model of the insect visual system, are likely to apply to visual systems in general.

  8. Spatiotemporal structure of visual receptive fields in macaque superior colliculus.

    2012-11-01

    Saccades are useful for directing the high-acuity fovea to visual targets that are of behavioral relevance. The selection of visual targets for eye movements involves the superior colliculus (SC), where many neurons respond to visual stimuli. Many of these neurons are also activated before and during saccades of specific directions and amplitudes. Although the role of the SC in controlling eye movements has been thoroughly examined, far less is known about the nature of the visual responses in this area. We have, therefore, recorded from neurons in the intermediate layers of the macaque SC, while using a sparse-noise mapping procedure to obtain a detailed characterization of the spatiotemporal structure of visual receptive fields. We find that SC responses to flashed visual stimuli start roughly 50 ms after the onset of the stimulus and last for on average ~70 ms. About 50% of these neurons are strongly suppressed by visual stimuli flashed at certain locations flanking the excitatory center, and the spatiotemporal pattern of suppression exerts a predictable influence on the timing of saccades. This suppression may, therefore, contribute to the filtering of distractor stimuli during target selection. We also find that saccades affect the processing of visual stimuli by SC neurons in a manner that is quite similar to the saccadic suppression and postsaccadic enhancement that has been observed in the cortex and in perception. However, in contrast to what has been observed in the cortex, decreased visual sensitivity was generally associated with increased firing rates, while increased sensitivity was associated with decreased firing rates. Overall, these results suggest that the processing of visual stimuli by SC receptive fields can influence oculomotor behavior and that oculomotor signals originating in the SC can shape perisaccadic visual perception.

    In women, the window of implantation is limited to a brief 2- to 3-day period characterized by optimal levels of circulating ovarian hormones and a receptive endometrium. Although the window of implantation is assumed to occur 8 to 10 days after ovulation in women, molecular markers of endometrial receptivity are necessary to determine optimal timing prior to embryo transfer. Previous studies showed that members of the bone morphogenetic protein (BMP) family are expressed in the uterus necessary for female fertility; however, the role of BMP7 during implantation and in late gestation is not known. To determine the contribution of BMP7 to female fertility, we generated Bmp7flox/flox-Pgr-cre+/- [BMP7 conditional knockout (cKO)] mice. We found that absence of BMP7 in the female reproductive tract resulted in subfertility due to uterine defects. At the time of implantation, BMP7 cKO females displayed a nonreceptive endometrium with elevated estrogen-dependent signaling. These implantation-related defects also affected decidualization and resulted in decreased expression of decidual cell markers such as Wnt4, Cox2, Ereg, and Bmp2. We also observed placental abnormalities in pregnant Bmp7 cKO mice, including excessive parietal trophoblast giant cells and absence of a mature placenta at 10.5 days post coitum. To establish possible redundant roles of BMP5 and BMP7 during pregnancy, we generated double BMP5 knockout/BMP7 cKO [BMP5/7 double knockout (DKO)] mice; however, we found that the combined deletion had no additive disruptive effect on fertility. Our studies indicate that BMP7 is an important factor during the process of implantation that contributes to healthy embryonic development. Copyright © 2017 Endocrine Society.

    Full Text Available The article studies and generalises existing approaches to identification of criteria of assessment of innovation receptivity of subjects of economic activity and also marks out main groups of methods of this assessment. It provides a chain of competences of an enterprise in the sphere of management of its innovation activity, which meets its passive and active innovation receptivity, which lies in the foundation of formation of the multiplicative approach to assessment of the current level of innovation receptivity of an enterprise. The article offers complex qualitative and quantitative indicators of active and also passive innovation receptivity of an enterprise. Further studies of the issue of assessment of the current level of innovation receptivity of economic subjects require clarification of capabilities of a more complete consideration of influence of the obtained financial results from the enterprise innovation activity upon this level.

    2016-12-01

    Associations linking parenting emotional climate and quality of parental social coaching with young adolescents' receptivity to parental social coaching were examined (N = 80). Parenting emotional climate was assessed with adolescent-reported parental warmth and hostility. Quality of parental social coaching (i.e., prosocial advice, benign framing) was assessed via parent-report and behavioral observations during a parent-adolescent discussion about negative peer evaluation. An adolescent receptivity latent variable score was derived from observations of adolescents' behavior during the discussion, change in adolescents' peer response plan following the discussion, and adolescent-reported tendency to seek social advice from the parent. Parenting climate moderated associations between coaching and receptivity: Higher quality coaching was associated with greater receptivity in the context of a more positive climate. Analyses suggested a stronger association between coaching and receptivity among younger compared to older adolescents. © 2015 The Authors.

    The International Atomic Energy Agency is undertaking a program for strengthening its safeguards on the recognition that safeguards must give assurance not only of the non-diversion of declared material or that declared facilities are not being misused, but also of the absence of any undeclared nuclear activities in States which have signed comprehensive safeguards agreements with the Agency. The IAEA has determined that the detection of undeclared nuclear activities and the creation of confidence in the continuing peaceful use of declared material and facilities is largely dependent on more information being made available to the Agency and on the capability of the Agency to make more effective use of this additional information, as well as existing information.

    Full Text Available Among the non-linear loads used in household, Compact Fluorescent Lamps (CFLs and LED lamps are becoming more widespread, while incandescent lamps are intended to be replaced by these types of lighting devices. LEDs and CFLs are significantly more efficient and economical than incandescent lamps, and are expected to be used in 100% of residential lighting in the future. As nonlinear loads, LEDs and CFLs produce highly distorted currents. A large number of customers using LEDs or CFLs for domestic, commercial and industrial lighting could determine important Power Quality problems. The paper reports experimental measurement results regarding Power Quality in indoor lighting systems. The harmonic absorptions of several types of luminaries are analyzed, highlighting the impact behavior of different lamps function of used luminaries’ technologies. The recorded harmonic absorption allows characterizing the harmonic spectrum variability of the investigated lamps.

  6. Effects of spike-triggered negative feedback on receptive-field properties.

    Science.gov (United States)

    Urdapilleta, Eugenio; Samengo, Inés

    2015-04-01

    Sensory neurons are often described in terms of a receptive field, that is, a linear kernel through which stimuli are filtered before they are further processed. If information transmission is assumed to proceed in a feedforward cascade, the receptive field may be interpreted as the external stimulus' profile maximizing neuronal output. The nervous system, however, contains many feedback loops, and sensory neurons filter more currents than the ones representing the transduced external stimulus. Some of the additional currents are generated by the output activity of the neuron itself, and therefore constitute feedback signals. By means of a time-frequency analysis of the input/output transformation, here we show how feedback modifies the receptive field. The model is applicable to various types of feedback processes, from spike-triggered intrinsic conductances to inhibitory synaptic inputs from nearby neurons. We distinguish between the intrinsic receptive field (filtering all input currents) and the effective receptive field (filtering only external stimuli). Whereas the intrinsic receptive field summarizes the biophysical properties of the neuron associated to subthreshold integration and spike generation, only the effective receptive field can be interpreted as the external stimulus' profile maximizing neuronal output. We demonstrate that spike-triggered feedback shifts low-pass filtering towards band-pass processing, transforming integrator neurons into resonators. For strong feedback, a sharp resonance in the spectral neuronal selectivity may appear. Our results provide a unified framework to interpret a collection of previous experimental studies where specific feedback mechanisms were shown to modify the filtering properties of neurons.

    2009-01-01

    The human endometrium is receptive for implantation of a blastocyst for only 4-5 days in each menstrual cycle. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Endometrial receptivity requires changes in the uterine luminal and glandular cells, particularly in terms of their secretory capacity and altered expression of adhesion molecules. In parallel with these changes, decidualisation (differentiation) of the endometrial stroma is initiated in women during the receptive phase, regardless of the presence of a blastocyst. Increased leucocyte numbers are also important. The microenvironments provided by the endometrium during the receptive phase and that support implantation are highly complex and constantly changing as implantation progresses. The present review provides a comprehensive overview of the cellular and molecular events of human implantation. It also summarises work from our laboratories emphasising the functional importance of proprotein convertase 6, along with key cytokines (interleukin-11, leukaemia inhibitory factor, activin A) and chemokines (including CX3CL1 and CCL14), during implantation. Of particular importance is how these mediators contribute to receptivity and how they are disturbed in infertile women. Factors that are critical for uterine receptivity may also be manipulated to provide new contraceptive strategies for women.

  8. Information Demand Pattern for Teams

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Modern organizations face the challenge of having to manage an increasing amount of information. The resulting information overload leads more and more to problems in decision making with potentially negative economic consequences. Decision-makers and knowledge intensive workers are especially affected. To address this problem, information demand patterns were proposed which capture organizational knowledge about the information demand of single roles. This work extends the concept of information demand patterns from single roles to teams. Using the knowledge intensive field of project management, the paper shows how to apply the concept of information demand patterns for a whole team. The contributions of this work are (1 the methodical approach to develop information demand patterns for teams, (2 an actual information demand pattern for a steering committee in the context of project management, (3 reflections on the differences between role patterns and team patterns.

    Many thousands of cortical neurons are activated by any single sensory stimulus, but the organization of these populations is poorly understood. For example, are neurons in mouse visual cortex--whose preferred orientations are arranged randomly--organized with respect to other response properties? Using high-speed in vivo two-photon calcium imaging, we characterized the receptive fields of up to 100 excitatory and inhibitory neurons in a 200 μm imaged plane. Inhibitory neurons had nonlinearly summating, complex-like receptive fields and were weakly tuned for orientation. Excitatory neurons had linear, simple receptive fields that can be studied with noise stimuli and system identification methods. We developed a wavelet stimulus that evoked rich population responses and yielded the detailed spatial receptive fields of most excitatory neurons in a plane. Receptive fields and visual responses were locally highly diverse, with nearby neurons having largely dissimilar receptive fields and response time courses. Receptive-field diversity was consistent with a nearly random sampling of orientation, spatial phase, and retinotopic position. Retinotopic positions varied locally on average by approximately half the receptive-field size. Nonetheless, the retinotopic progression across the cortex could be demonstrated at the scale of 100 μm, with a magnification of ≈ 10 μm/°. Receptive-field and response similarity were in register, decreasing by 50% over a distance of 200 μm. Together, the results indicate considerable randomness in local populations of mouse visual cortical neurons, with retinotopy as the principal source of organization at the scale of hundreds of micrometers.

  10. Receptivity of Hypersonic Boundary Layers to Distributed Roughness and Acoustic Disturbances

    2013-01-01

    Boundary-layer receptivity and stability of Mach 6 flows over smooth and rough seven-degree half-angle sharp-tipped cones are numerically investigated. The receptivity of the boundary layer to slow acoustic disturbances, fast acoustic disturbances, and vortical disturbances is considered. The effects of three-dimensional isolated roughness on the receptivity and stability are also simulated. The results for the smooth cone show that the instability waves are generated in the leading edge region and that the boundary layer is much more receptive to slow acoustic waves than to the fast acoustic waves. Vortical disturbances also generate unstable second modes, however the receptivity coefficients are smaller than that of the slow acoustic wave. Distributed roughness elements located near the nose region decreased the receptivity of the second mode generated by the slow acoustic wave by a small amount. Roughness elements distributed across the continuous spectrum increased the receptivity of the second mode generated by the slow and fast acoustic waves and the vorticity wave. The largest increase occurred for the vorticity wave. Roughness elements distributed across the synchronization point did not change the receptivity of the second modes generated by the acoustic waves. The receptivity of the second mode generated by the vorticity wave increased in this case, but the increase is lower than that occurred with the roughness elements located across the continuous spectrum. The simulations with an isolated roughness element showed that the second mode waves generated by the acoustic disturbances are not influenced by the small roughness element. Due to the interaction, a three-dimensional wave is generated. However, the amplitude is orders of magnitude smaller than the two-dimensional wave.

    In light of the current and future threats to global water security the current research focuses on trialing interventions to promote urban water conservation. We report an experimental study designed to test the long-term impact of three different interventions on household water consumption in South East Queensland. Participants from 221 households were recruited and completed an initial survey, and their houses were fitted with smart water meters which measured total water usage at 5 s intervals. Households were allocated into one of four conditions: a control group and three interventions groups (water saving information alone, information plus a descriptive norm manipulation, and information plus tailored end-user feedback). The study is the first to use smart water metering technology as a tool for behaviour change as well as a way to test the effectiveness of demand management interventions. Growth curve modelling revealed that compared to the control, the three intervention groups all showed reduced levels of household consumption (an average reduction of 11.3 L per person per day) over the course of the interventions, and for some months afterwards. All interventions led to significant water savings, but long-term household usage data showed that in all cases, the reduction in water use resulting from the interventions eventually dissipated, with water consumption returning to pre-intervention levels after approximately 12 months. Implications for water demand management programs are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    An understanding of the relationship of economic growth and potential petroleum product demand is needed to forecast the potential for North American oil demand growth as well as knowledge of world supply and price. The bullish expectations for economic growth in the US and Canada auger well for North American refiners and marketeers. The growth in world economic output forecast, however, means a larger oil demand and an increase in OPEC`s pricing power. Such price increases could depress North American oil demand growth.

    A computer model of communications demand is being developed to permit dynamic simulations of the long-term evolution of demand for communications media in the U.K. to be made under alternative assumptions about social, economic and technological trends in British Telecom's business environment. The context and objectives of the project and the potential uses of the model are reviewed, and four key concepts in the demand for communications media, around which the model is being structured are discussed: (1) the generation of communications demand; (2) substitution between media; (3) technological convergence; and (4) competition. Two outline perspectives on the model itself are given.

    Impaired endometrial receptivity is an important contributing factor to implantation failure. Uterine leiomyomas are widely prevalent steroid hormone-dependent benign tumors that act as a restraint to conception and successful outcome of pregnancies. Reports are available, which suggest that leiomyomas have negative influence on endometrial receptivity to blastocyst implantation. The aim of the present review is to provide a comprehensive picture of the current knowledge of the effect of uterine leiomyomas on the architectural, cellular, and molecular determinants of endometrial receptivity. Understanding the potential role of these factors will provide insight into the underlying mechanisms of leiomyoma-associated infertility and provide new areas for basic and translational research.

    This mixed methods study explores college students' readiness-to-change and receptivity to treatment for problem Internet overuse behaviors. Focus groups were conducted with 27 college students who self-identified as Internet over-users, and had experienced biopsychosocial problems related to Internet overuse. Participants completed standardized questionnaires assessing their Internet use and sociodemographic forms. Focus groups explored readiness to change problem Internet overuse behaviors and receptivity to treatment. Similar to college students with other addictive behaviors, students with problem Internet overuse fall along a continuum vis-à-vis readiness-to-change their behaviors. Over half of the participants were receptive to treatment for their problem Internet overuse behaviors.

    In this paper I discuss the relationship between two different approaches to critical theory – the reflective and the receptive approaches. I show how it can be fruitful to discuss the relationship between Habermas and Foucault through this distinction. My point is that whereas Habermas focusses...... on critique as a reflexive activity, Foucault mainly focusses on the receptive conditions for critique to be possible. I argue further that Foucault focusses on the receptive aspects of critique, the quest for universality is not as pressing as it is in Habermas’ approach, because problematizing critique can...

    Reception theory, a newly developed discipline, is an audience-oriented film title translation approach. According to Reception Aesthetics, the historical life of a literary work is unthinkable without the active participation of the readers. With the reception theory as the theoretical background, it will pilot the basic points of the translation of film titles, namely, informative value, cultural value, aesthetic value, and commercial value, with the five pragmatic methods of general translation. Further-more, it also takes the factor of intercultural factors into consideration when discussing this topic.

  19. [Freud as neuropathologist, his reception in France before 1910].

    1999-08-01

    Even before 1910 Freud in Paris was not unknown. His relation to Charcot first and the reception of his papers by Charcot's followers (mainly Raymond, Marie, Brissaud) later represent a particular chapter of history. This is well documented by Charcot's letters to Freud (hitherto published only in French), by Freud's French articles as well as by many medical theses (Paris, Lyon, Nancy, Bordeaux) discussing the pros and cons. Two topics were focussed. First there was a neurological dispute about Little's disease, its clinical vignette, etiologies, and its spinal and cerebral localisations. Freud argued there to be a nosographic entity. Most of Charcot's disciples, however, pleaded against the idea of an entity for such different pathological forms. This was followed by a discussion about Freuds doctrine of neuroses and their sexual origin, which Freud opposed to the French theories of heredity and degeneration. Both of the discussions were without personal encounter and without a direct exchange of views between the protagonists. Which did not cause it to be less vivid and intense. This proves Freud's standing as an internationally acknowledged expert for neuropathological aspects of the child. However, starting in 1900, Freud retired from the neurological discussion and the Paris scene. The dispute about Little's disease faded away and the discussion about neuroses became occupied by Janet's writings. The neuropathologist Freud eclipsed the psychoanalyst Freud. Hence Freud's repeated complaints not to have been well received by the French.

  20. Wireless Local Area Networks with Multiple-Packet Reception Capability

    Zhang, Ying Jun; Liew, Soung Chang

    2007-01-01

    Thanks to its simplicity and cost efficiency, wireless local area network (WLAN) enjoys unique advantages in providing high-speed and low-cost wireless services in hot spots and indoor environments. Traditional WLAN medium-access-control (MAC) protocols assume that only one station can transmit at a time: simultaneous transmissions of more than one station causes the destruction of all packets involved. By exploiting recent advances in PHY-layer multiuser detection (MUD) techniques, it is possible for a receiver to receive multiple packets simultaneously. This paper argues that such multipacket reception (MPR) capability can greatly enhance the capacity of future WLANs. In addition, it provides the MAC-layer and PHY-layer designs needed to achieve the improved capacity. First, to demonstrate MUD/MPR as a powerful capacity-enhancement technique, we prove a "super-linearity" result, which states that the system throughput per unit cost increases as the MPR capability increases. Second, we show that the commonly...

    Polycystic ovary syndrome (PCOS), a complex endocrine disorder, is a leading cause of female infertility. An obvious reason for infertility in PCOS women is anovulation. However, success rate with high quality embryos selected by assisted reproduction techniques in PCOS patients still remain low with a high rate of early clinical pregnancy loss, suggesting a problem in uterine receptivity. Using a dehydroepiandrosterone-induced mouse model of PCOS, some potential causes of decreased fertility in PCOS patients were explored. In our study, ovulation problem also causes sterility in PCOS mice. After blastocysts from normal mice are transferred into uterine lumen of pseudopregnant PCOS mice, the rate of embryo implantation was reduced. In PCOS mouse uteri, the implantation-related genes are also dysregulated. Additionally, artificial decidualization is severely impaired in PCOS mice. The serum estrogen level is significantly higher in PCOS mice than vehicle control. The high level of estrogen and potentially impaired LIF-STAT3 pathway may lead to embryo implantation failure in PCOS mice. Although there are many studies about effects of PCOS on endometrium, both embryo transfer and artificial decidualization are applied to exclude the effects from ovulation and embryos in our study.

  2. Categorically distinct types of receptive fields in early visual cortex.

    2016-05-01

    In the visual cortex, distinct types of neurons have been identified based on cellular morphology, response to injected current, or expression of specific markers, but neurophysiological studies have revealed visual receptive field (RF) properties that appear to be on a continuum, with only two generally recognized classes: simple and complex. Most previous studies have characterized visual responses of neurons using stereotyped stimuli such as bars, gratings, or white noise and simple system identification approaches (e.g., reverse correlation). Here we estimate visual RF models of cortical neurons using visually rich natural image stimuli and regularized regression system identification methods and characterize their spatial tuning, temporal dynamics, spatiotemporal behavior, and spiking properties. We quantitatively demonstrate the existence of three functionally distinct categories of simple cells, distinguished by their degree of orientation selectivity (isotropic or oriented) and the nature of their output nonlinearity (expansive or compressive). In addition, these three types have differing average values of several other properties. Cells with nonoriented RFs tend to have smaller RFs, shorter response durations, no direction selectivity, and high reliability. Orientation-selective neurons with an expansive output nonlinearity have Gabor-like RFs, lower spontaneous activity and responsivity, and spiking responses with higher sparseness. Oriented RFs with a compressive nonlinearity are spatially nondescript and tend to show longer response latency. Our findings indicate multiple physiologically defined types of RFs beyond the simple/complex dichotomy, suggesting that cortical neurons may have more specialized functional roles rather than lying on a multidimensional continuum.

  3. Multi-Round Contention in Wireless LANs with Multipacket Reception

    Jun, Ying

    2010-01-01

    Multi-packet reception (MPR) has been recognized as a powerful capacity-enhancement technique for random-access wireless local area networks (WLANs). As is common with all random access protocols, the wireless channel is often under-utilized in MPR WLANs. In this paper, we propose a novel multi-round contention random-access protocol to address this problem. This work complements the existing random-access methods that are based on single-round contention. In the proposed scheme, stations are given multiple chances to contend for the channel until there are a sufficient number of ``winning" stations that can share the MPR channel for data packet transmission. The key issue here is the identification of the optimal time to stop the contention process and start data transmission. The solution corresponds to finding a desired tradeoff between channel utilization and contention overhead. In this paper, we conduct a rigorous analysis to characterize the optimal strategy using the theory of optimal stopping. An int...

    Based on the acoustic radiation theory of a dipole source, the influence of the transducer reception pattern is studied for magnetoacoustic tomography with magnetic induction (MAT-MI). Numerical studies are conducted to simulate acoustic pressures, waveforms, and reconstructed images with unidirectional, omnidirectional, and strong directional transducers. With the analyses of equivalent and projection sources, the influences of the model dimension and the layer effect are qualitatively analyzed to evaluate the performance of MAT-MI. Three-dimensional simulation studies show that the strong directional transducer with a large radius can reduce the influences of equivalent sources, projection sources, and the layer effect effectively, resulting in enhanced pressure and improved image contrast, which is beneficial for boundary pressure extraction in conductivity reconstruction. The reconstructed conductivity contrast images present the conductivity boundaries as stripes with different contrasts and polarities, representing the values and directions of the conductivity changes of the scanned layer. The favorable results provide solid evidence for transducer selection and suggest potential practical applications of MAT-MI in biomedical imaging.

  5. Spatiotemporal receptive fields: a dynamical model derived from cortical architectonics.

    We assume that the mammalian neocortex is built up out of some six layers which differ in their morphology and their external connections. Intrinsic connectivity is largely excitatory, leading to a considerable amount of positive feedback. The majority of cortical neurons can be divided into two main classes: the pyramidal cells, which are said to be excitatory, and local cells (most notably the non-spiny stellate cells), which are said to be inhibitory. The form of the dendritic and axonal arborizations of both groups is discussed in detail. This results in a simplified model of the cortex as a stack of six layers with mutual connections determined by the principles of fibre anatomy. This stack can be treated as a multi-input-multi-output system by means of the linear systems theory of homogeneous layers. The detailed equations for the simulation are derived in the Appendix. The results of the simulations show that the temporal and spatial behaviour of an excitation distribution cannot be treated separately. Further, they indicate specific processing in the different layers and some independence from details of wiring. Finally, the simulation results are applied to the theory of visual receptive fields. This yields some insight into the mechanisms possibly underlying hypercomplexity, putative nonlinearities, lateral inhibition, oscillating cell responses, and velocity-dependent tuning curves.

  6. Receptive field plasticity of neurons in rat auditory cortex

    2004-01-01

    Using conventional electrophysiological technique, we investigated the plasticity of the frequency receptive fields (RF) of auditory cortex (AC) neurons in rats. In the AC, when the frequency difference between conditioning stimulus frequency (CSF) and the best frequency (BF) was in the range of 1-4 kHz, the frequency RF of AC neurons shifted. The smaller the differences between CSF and BF, the higher the probability of the RF shift and the greater the degree of the RF shift. To some extent, the plasticity of RF was dependent on the duration of the session of conditioning stimulus (CS). When the frequency difference between CSF and BF was bigger, the duration of the CS session needed to induce the plasticity was longer. The recovery time course of the frequency RF showed opposite changes after CS cessation.The RF shift could be induced by the frequency that was either higher or lower than the control BF, demonstrating no clear directional preference. The frequency RF of some neurons showed bidirectional shift, and the RF of other neurons showed single directional shift. The results suggest that the frequency RF plasticity of AC neurons could be considered as an ideal model for studying plasticity mechanism. The present study also provides important evidence for further study of learning and memory in auditory system.

    Technology invention, innovation and transfer have been a constant of human evolution. Facing humanity is the threat of anthropogenic climate change, the solution to which is to reduce the rate at which greenhouse gasses (GHGs) are building up in the atmosphere and to deal with the impacts of climate variability and change. To deal with the global crisis requires technology invention, innovation and transfer and changes in behaviour that reduce the GHGs intensity of energy services. Meanwhile, the poverty reduction and development agenda are being shaped by the Millennium Development Goals, which slowly appears to be gaining buy-in. The question is how will the accelerated receipt of cleaner energy technologies can be successfully achieved in marginalised communities in developing countries? The paper considers a range of drivers, case studies and projects that are being undertaken as early Clean Development Mechanism experiments under the banner of the International SouthSouthNorth Group. It discusses the drivers of technology transfer and starts to unpack the elements of successful receptivity through selection and ownership of the newly introduced environmentally safe technologies (ESTs) for the provision of energy services.

  8. Environmental temperature modulates olfactory reception in Drosophila melanogaster.

    Sensory systems, including the olfactory system, are able to adapt to changing environmental conditions. In nature, changes in temperature modify the volatility and concentration of odorants in the air. If the olfactory system does not adapt to these changes, it could relay wrong information about the distance to or direction of odor sources. Recent behavioral studies in Drosophila melanogaster showed olfactory acclimation to temperature. In this report, we investigated if temperature affects olfaction at the level of the receptors themselves. With this aim, we performed electroantennograms (EAGs) and single sensillum recordings (SSRs) to measure the response to several odorants in flies that had been submitted to temperature treatments. In response to all tested odorants, the amplitude of the EAGs increased in flies that had been exposed to a higher temperature and decreased after cold treatment, revealing that at least part of the reported change in olfactory perception happens at reception level. SSRs of odorant stimulated basiconic sensilla ab2 and ab3 showed some changes in the number of spikes after heat or cold treatment. However, the number and shape of spontaneous action potentials were unaffected, suggesting that the observed changes related specifically to the olfactory function of the neurons.

    2001-05-01

    Previously, most mammalian auditory systems research has concentrated on human sensory perception whose frequencies are lower than 20 kHz. The implementations almost always used analog VLSI design. Due to the complexity of the model, it is difficult to implement these algorithms using current digital technology. This paper introduces a simplified model of biosonic reception system in bats and its implementation in the ``Chiroptera Inspired Robotic CEphaloid'' (CIRCE) project. This model consists of bandpass filters, a half-wave rectifier, low-pass filters, automatic gain control, and spike generation with thresholds. Due to the real-time requirements of the system, the system employs Butterworth filters and advanced field programmable gate array (FPGA) architectures to provide a viable solution. The ultrasonic signal processing is implemented on a Xilinx FPGA Virtex II device in real time. In the system, 12-bit input echo signals from receivers are sampled at 1 M samples per second for a signal frequency range from 20 to 200 kHz. The system performs a 704-channel per ear auditory pipeline operating in real time. The output of the system is a coded time series of threshold crossing points. Comparing hardware implementation with fixed-point software, the system shows significant performance gains with no loss of accuracy.

    2005-04-01

    This paper describes the results from the second season of research to develop and evaluate the performance of new Automated Demand Response (Auto-DR) hardware and software technology in large facilities. Demand Response (DR) is a set of activities to reduce or shift electricity use to improve the electric grid reliability and manage electricity costs. Fully-Automated Demand Response does not involve human intervention, but is initiated at a home, building, or facility through receipt of an external communications signal. We refer to this as Auto-DR. The evaluation of the control and communications must be properly configured and pass through a set of test stages: Readiness, Approval, Price Client/Price Server Communication, Internet Gateway/Internet Relay Communication, Control of Equipment, and DR Shed Effectiveness. New commissioning tests are needed for such systems to improve connecting demand responsive building systems to the electric grid demand response systems.

    2009-05-11

    This report summarizes the Lawrence Berkeley National Laboratory's research to date in characterizing energy efficiency and open automated demand response opportunities for industrial refrigerated warehouses in California. The report describes refrigerated warehouses characteristics, energy use and demand, and control systems. It also discusses energy efficiency and open automated demand response opportunities and provides analysis results from three demand response studies. In addition, several energy efficiency, load management, and demand response case studies are provided for refrigerated warehouses. This study shows that refrigerated warehouses can be excellent candidates for open automated demand response and that facilities which have implemented energy efficiency measures and have centralized control systems are well-suited to shift or shed electrical loads in response to financial incentives, utility bill savings, and/or opportunities to enhance reliability of service. Control technologies installed for energy efficiency and load management purposes can often be adapted for open automated demand response (OpenADR) at little additional cost. These improved controls may prepare facilities to be more receptive to OpenADR due to both increased confidence in the opportunities for controlling energy cost/use and access to the real-time data.

    Diversity reception technology is introduced into ultraviolet communication area in this article with theory analysis and practical experiment. The idea of diversity reception was known as a critical effective method in wireless communication area that improves the Gain significantly especially for the multi-scattering channel. A theoretical modeling and simulation method are proposed to depict the principle and feasibility of diversity reception adopted in UV communication. Besides, an experimental test-bed using ultraviolet LED and dual receiver of photomultiplier tube is setup to characterize the effects of diversity receiving in non-line-of-sight (NLOS) ultraviolet communication system. The experiment results are compared with the theoretical ones to verify the accuracy of theoretical modeling and the effect of diversity reception. Equal gain combining (EGC) method was adopted as the diversity mechanism in this paper. The research results of theory and experiment provide insight into the channel characteristics and achievable capabilities of ultraviolet communication system with diversity receiving method.

    1991-01-01

    A detection model to identify the presence of Galileo optical communications from an Earth-based Transmitter (GOPEX) signal by processing multiple signal receptions extracted from the camera images is described. The model decomposes a multi-signal reception camera image into a set of images so that the location of the pixel being illuminated is known a priori and the laser can illuminate only one pixel at each reception instance. Numerical results show that if effects on the pointing error due to atmospheric refraction can be controlled to between 20 to 30 microrad, the beam divergence of the GOPEX laser should be adjusted to be between 30 to 40 microrad when the spacecraft is 30 million km away from Earth. Furthermore, increasing beyond 5 the number of receptions for processing will not produce a significant detection probability advantage.

    This investigation, consisting of two experiments, was designed to assess the effects of autistic immediate echolalia on acquisition and generalization of receptive labeling tasks. Experiment 1 addressed whether autistic children could use their echolalia to facilitate acquisition. The results indicated that incorporating echolalia (echo of the requested object's label) into the task before manual response (handing the requested object to the experimenter) facilitated receptive labeling.

    Advertisement of fast food on TV may contribute to youth obesity. The goal of the study was to use cued recall to determine whether TV fast-food advertising is associated with youth obesity. A national sample of 2541 U.S. youth, aged 15-23 years, were surveyed in 2010-2011; data were analyzed in 2012. Respondents viewed a random subset of 20 advertisement frames (with brand names removed) selected from national TV fast-food restaurant advertisements (n=535) aired in the previous year. Respondents were asked if they had seen the advertisement, if they liked it, and if they could name the brand. A TV fast-food advertising receptivity score (a measure of exposure and response) was assigned; a 1-point increase was equivalent to affirmative responses to all three queries for two separate advertisements. Adjusted odds of obesity (based on self-reported height and weight), given higher TV fast-food advertising receptivity, are reported. The prevalence of overweight and obesity, weighted to the U.S. population, was 20% and 16%, respectively. Obesity, sugar-sweetened beverage consumption, fast-food restaurant visit frequency, weekday TV time, and TV alcohol advertising receptivity were associated with higher TV fast-food advertising receptivity (median=3.3 [interquartile range: 2.2-4.2]). Only household income, TV time, and TV fast-food advertising receptivity retained multivariate associations with obesity. For every 1-point increase in TV fast-food advertising receptivity score, the odds of obesity increased by 19% (OR=1.19, 95% CI=1.01, 1.40). There was no association between receptivity to televised alcohol advertisements or fast-food restaurant visit frequency and obesity. Using a cued-recall assessment, TV fast-food advertising receptivity was found to be associated with youth obesity. © 2013 American Journal of Preventive Medicine.

  11. Effects of Nose Radius and Aerodynamic Loading on Leading Edge Receptivity

    1998-01-01

    An analysis is presented of the effects of airfoil thickness and mean aerodynamic loading on boundary-layer receptivity in the leading-edge region. The case of acoustic free-stream disturbances, incident on a thin cambered airfoil with a parabolic leading edge in a low Mach number flow, is considered. An asymptotic analysis based on large Reynolds number is developed, supplemented by numerical results. The airfoil thickness distribution enters the theory through a Strouhal number based on the nose radius of the airfoil, S = (omega)tau(sub n)/U, where omega is the frequency of the acoustic wave and U is the mean flow speed. The influence of mean aerodynamic loading enters through an effective angle-of-attack parameter ti, related to flow around the leading edge from the lower surface to the upper. The variation of the receptivity level is analyzed as a function of S, mu, and characteristics of the free-stream acoustic wave. For an unloaded leading edge, a finite nose radius dramatically reduces the receptivity level compared to that for a flat plate, the amplitude of the instability waves in the boundary layer being decreased by an order of magnitude when S = 0.3. Modest levels of aerodynamic loading are found to further decrease the receptivity level for the upper surface of the airfoil, while an increase in receptivity level occurs for the lower surface. For larger angles of attack close to the critical angle for boundary layer separation, a local rise in the receptivity level occurs for the upper surface, while for the lower surface the receptivity decreases. The effects of aerodynamic loading are more pronounced at larger values of S. Oblique acoustic waves produce much higher receptivity levels than acoustic waves propagating downstream parallel to the airfoil chord.

    Successful embryonic implantation is the result of a receptive endometrium, a functional embryo at the blastocyst stage and a synchronized dialog between maternal and embryonic tissues. Successful implantation requires the endometrium to undergo steroid-dependent change during each menstrual cycle, exhibiting a short period of embryonic receptivity known as the window of implantation. The term “endometrial receptivity” was introduced to define the state of the endometrium during the window of...

    MAICON DOUGLAS ARENAS-DE-SOUZA

    Full Text Available ABSTRACT Theobroma subincanum (cupuí is a fruit species native to the Amazon region. Fruits are enjoyed by local people and consumed both as fresh fruit such as juice, nectar or soft drinks. Reproductive biology studies provide contributions to conservation strategies and plant improvement. The present study aimed to analyze the stigmatic receptivity and pollen viability of T. subincanum. This study was developed in a forest fragment located in the urban perimeter of the municipality of Alta Floresta, MT. In the flowering period, flower buds or flowers were collected in seven different times, as follows: 10 pm, 02 am, 06 am, 10 am, 2 pm, 6 pm, and 10 pm. Pollen viability was estimated by reactive Alexander (1969 and stigmatic receptivity using 3% hydrogen peroxide. Pollen viability averages were submitted to analysis of variance, while stigmatic receptivity was analyzed by average percentage in each interval. Four floral stages were characterized based on flower opening, and from 6 am, fully opened flowers have already been found (stage IV. The percentage of pollen viability was not affected by collection times. In the stigmatic receptivity analysis, it was observed that in all floral stages, stigma was receptive; however, the highest percentages of stigmatic receptivity were found from 2 am to 10 am of the same day, which is the most propitious time for fertilization. Pollen collection of T. subincanum may be performed in any of schedules evaluated in this study, since it is held with high viability percentage.

    Background: Mentally ill prisoners, when requiring admission in a psychiatric facility, have to be admitted only by a reception order of a judicial magistrate and convicts by warrants issued by the Government to jail superintendents and the superintendent of the hospital. Both can be only under Section 27 of The Mental Health Act, 1987. Materials and Methods: A study of the contents of reception order and warrants regarding the acts and section under which they were issued over 1 year period for the admission of the patients in the criminal ward of the Institute of Mental Health was carried out. Results: Only three reception orders quoted Section 27 out of 54 patients admitted under a reception order. Nineteen patients were admitted by the jail superintendents. Discussion: Various issues that were found in the reception order and their consequences are discussed, and a possible response to these issues is mooted. Conclusion: Almost none of the reception orders were found to be proper. This deficit needs to be rectified by sensitizing the various authorities. PMID:27385850

    Visual cortex is retinotopically organized so that neighboring populations of cells map to neighboring parts of the visual field. Functional magnetic resonance imaging allows us to estimate voxel-based population receptive fields (pRF), i.e., the part of the visual field that activates the cells within each voxel. Prior, direct, pRF estimation methods(1) suffer from certain limitations: 1) the pRF model is chosen a-priori and may not fully capture the actual pRF shape, and 2) pRF centers are prone to mislocalization near the border of the stimulus space. Here a new topographical pRF estimation method(2) is proposed that largely circumvents these limitations. A linear model is used to predict the Blood Oxygen Level-Dependent (BOLD) signal by convolving the linear response of the pRF to the visual stimulus with the canonical hemodynamic response function. PRF topography is represented as a weight vector whose components represent the strength of the aggregate response of voxel neurons to stimuli presented at different visual field locations. The resulting linear equations can be solved for the pRF weight vector using ridge regression(3), yielding the pRF topography. A pRF model that is matched to the estimated topography can then be chosen post-hoc, thereby improving the estimates of pRF parameters such as pRF-center location, pRF orientation, size, etc. Having the pRF topography available also allows the visual verification of pRF parameter estimates allowing the extraction of various pRF properties without having to make a-priori assumptions about the pRF structure. This approach promises to be particularly useful for investigating the pRF organization of patients with disorders of the visual system.

    2016-05-01

    Full Text Available The current escalation in user demand for web contents, particularly Video on Demand (VoD, is causing a continu‐ ing increase in both the types of web traffic and the volumes of data transmitted. The greater demand arises from the new means of communication employed by individuals and companies, as well as the development of readily usable applications distributed by ‘app stores’. In this paper, we suggest that the stakeholders of a VoD frame‐ work, the Content Providers (CPs and the Internet Service Providers (telcos/ISPs, should guarantee a solid Quality of Experience (QoE to the end user through two potential investments: either in ultra-broadband (UBB or in the technologies for the acceleration of web content, known as the Content Delivery Network (CDN and Transparent Internet Caching (TIC. The aim of the paper is to analyse these investments in terms of providers' profits. The base hypothesis is that the investments are subsidized by the CPs, which, in recent years, have indeed been directing a large part of their revenues towards investments in network infrastructure.

    The production and consumption of electricity is a major source of CO{sub 2} emissions in Europe and elsewhere. In turn, the manufacturing sectors are significant end-users of electricity. In contrast to most papers in the literature, which focus on the supply-side, this study tackles the demand-side of electricity. An input-output approach combined with a sensitivity analysis has been developed to analyse the direct and indirect consumptions of electricity by eighteen manufacturing sectors in fifteen European countries, with indirect electricity demand related to the purchase of industrial products from other sectors which, in turn, require the consumption of electricity in their manufacturing processes. We identify the industrial transactions and sectors, which account for a greater share of electricity demand. In addition, the impact of an electricity price increase on the costs and prices of manufacturing products is simulated through a price model, allowing us to identify those sectors whose manufacturing costs are most sensitive to an increase in the electricity price.

    ENGLISH ABSTRACT: It is commonly assumed that intermittent demand appears randomly, with many periods without demand; but that when it does appear, it tends to be higher than unit size. Basic and well-known forecasting techniques and stock policies perform very poorly with intermittent demand, making new approaches necessary. To select the appropriate inventory management policy, it is important to understand the demand pattern for the items, especially when demand is intermittent. The use of a forecasting method designed for an intermittent demand pattern, such as Croston’s method, is required instead of a simpler and more common approach such as exponential smoothing. The starting point is to establish taxonomic rules to select efficiently the most appropriate forecasting and stock control policy to cope with thousands of items found in real environments. This paper contributes to the state of the art in: (i categorisation of the demand pattern; (ii methods to forecast intermittent demand; and (iii stock control methods for items with intermittent demand patterns. The paper first presents a structured literature review to introduce managers to the theoretical research about how to deal with intermittent demand items in both forecasting and stock control methods, and then it points out some research gaps for future development for the three topics.

    The extent of the receptive period may determine the mating strategies employed by female crabs to obtain mates. Here, we studied the receptivity of female Neohelice granulata (Dana, 1851) in the laboratory, including the form of the vulvae and the anatomy of the seminal receptacle (SR). We examined the factors that influence the duration of receptivity by comparing two populations inhabiting contrasting habitats: Mar Chiquita Coastal lagoon (MCL), which is an oligo-polyhaline estuary, and San Antonio Oeste (SAO), which is an eu-hyperhaline marine bay. Non-receptive females have immobile vulva opercula, while receptive females have mobile opercula. Histological sections of the SR showed that the degree of epithelium secretions was associated with the receptive stage of females, and they may be involved in the maintenance of viable sperm and in the dehiscence of spermatophores. The existence of a special tissue at the junction of the oviduct and the SR was described and proposed as an internal mechanism influencing the timing of ovulation. The duration of receptivity was dependent on the SR load and the capacity to lay eggs. Thus, females with empty SR exhibited longer receptivity and did not lay eggs, while those with full SR exhibited shorter receptivity and always laid eggs. Interpopulation differences showed that females from SAO had shorter receptivity and heavier SR and laid eggs more frequently than females from MCL. Based on our results, we suggest that N. granulata females can adjust the duration of their receptivity and control the moment of fertilization according to different internal mechanisms related to the morphology of the vulvae, the fullness of the SR and anatomical attributes of the SR. An important consequence of this control is greater sperm competition. The extent of the receptive period and the number of times that a female could become receptive in a single reproductive season may also depend on the habitat characteristics.

    We provide various estimates of temperature effect for accommodating seasonality in energy demand, particularly natural gas demand. We exploit temperature response and monthly temperature distribution to estimate the temperature effect on natural gas demand. Both local and global smoothed temperature responses are estimated from empirical relationship between hourly temperature and hourly energy consumption data during the sample period (1990 - 1996). Monthly temperature distribution estimates are obtained by kernel density estimation from temperature dispersion within a month. We integrate temperature response and monthly temperature density over all the temperatures in the sample period to estimate temperature effect on energy demand. Then, estimates of temperature effect are compared between global and local smoothing methods. (author). 15 refs., 14 figs., 2 tabs.

    A lot of people lost their lives in the tremendous earthquake in Tohoku region on March 11. A large capacity of electric power plants in TEPCO area was also damaged and large scale power shortage in this summer is predicted. In this situation, electricity customers are making great effort to save electricity to avoid planned outage. Customers take actions not only by their selves but also by some customers' cooperative movements. All actions taken actually are based on responses to request form the government or voluntary decision. On the other hand, demand response based on a financial stimulus is not observed as an actual behavior. Saving electricity by this demand response only discussed in the newspapers. In this commentary, the events regarding electricity-saving measure after this disaster are described and the discussions on demand response, especially a raise in power rate, are put into shapes in the context of this electricity supply-demand gap.

  12. Receptive fields of visual neurons: the early years.

    Spillmann, Lothar

    2014-01-01

    This paper traces the history of the visual receptive field (RF) from Hartline to Hubel and Wiesel. Hartline (1938, 1940) found that an isolated optic nerve fiber in the frog could be excited by light falling on a small circular area of the retina. He called this area the RF, using a term first introduced by Sherrington (1906) in the tactile domain. In 1953 Kuffler discovered the antagonistic center-surround organization of cat RFs, and Barlow, Fitzhugh, and Kuffler (1957) extended this work to stimulus size and state of adaptation. Shortly thereafter, Lettvin and colleagues (1959) in an iconic paper asked "what the frog's eye tells the frog's brain". Meanwhile, Jung and colleagues (1952-1973) searched for the perceptual correlates of neuronal responses, and Jung and Spillmann (1970) proposed the term perceptive field (PF) as a psychophysical correlate of the RF. The Westheimer function (1967) enabled psychophysical measurements of the PF center and surround in human and monkey, which correlated closely with the underlying RF organization. The sixties and seventies were marked by rapid progress in RF research. Hubel and Wiesel (1959-1974), recording from neurons in the visual cortex of the cat and monkey, found elongated RFs selective for the shape, orientation, and position of the stimulus, as well as for movement direction and ocularity. These findings prompted the emergence in visual psychophysics of the concept of feature detectors selective for lines, bars, and edges, and contributed to a model of the RF in terms of difference of Gaussians (DOG) and Fourier channels. The distinction between simple, complex, and hypercomplex neurons followed. Although RF size increases towards the peripheral retina, its cortical representation remains constant due to the reciprocal relationship with the cortical magnification factor (M). This constitutes a uniform yardstick for M-scaled stimuli across the retina. Developmental studies have shown that RF properties are not fixed

    2011-07-17

    Receptive fields in primary visual cortex (V1) are categorized as simple or complex, depending on their spatial selectivity to stimulus contrast polarity. We studied the dependence of this classification on visual context by comparing, in the same cell, the synaptic responses to three classical receptive field mapping protocols: sparse noise, ternary dense noise and flashed Gabor noise. Intracellular recordings revealed that the relative weights of simple-like and complex-like receptive field components were scaled so as to make the same receptive field more simple-like with dense noise stimulation and more complex-like with sparse or Gabor noise stimulations. However, once these context-dependent receptive fields were convolved with the corresponding stimulus, the balance between simple-like and complex-like contributions to the synaptic responses appeared to be invariant across input statistics. This normalization of the linear/nonlinear input ratio suggests a previously unknown form of homeostatic control of V1 functional properties, optimizing the network nonlinearities to the statistical structure of the visual input.

    The receptivity to freestream sound of the laminar boundary layer over a semi-infinite flat plate with an elliptic leading edge is simulated numerically. The incompressible flow past the flat plate is computed by solving the full Navier-Stokes equations in general curvilinear coordinates. A finite-difference method which is second-order accurate in space and time is used. Spatial and temporal developments of the Tollmien-Schlichting wave in the boundary layer, due to small-amplitude time-harmonic oscillations of the freestream velocity that closely simulate a sound wave travelling parallel to the plate, are observed. The effect of leading-edge curvature is studied by varying the aspect ratio of the ellipse. The boundary layer over the flat plate with a sharper leading edge is found to be less receptive. The relative contribution of the discontinuity in curvature at the ellipse-flat-plate juncture to receptivity is investigated by smoothing the juncture with a polynomial. Continuous curvature leads to less receptivity. A new geometry of the leading edge, a modified super ellipse, which provides continuous curvature at the juncture with the flat plate, is used to study the effect of continuous curvature and inherent pressure gradient on receptivity.

    Neuroimaging studies have shed light on cortical language organization, with findings implicating the left and right temporal lobes in speech processing converging to a left-dominant pattern. Findings highlight the fact that the state of theoretical language knowledge is ahead of current clinical language mapping methods, motivating a rethinking of these approaches. The authors used magnetoencephalography and multiple tasks in seven candidates for resective epilepsy surgery to investigate language organization. The authors scanned 12 control subjects to investigate the time course of bilateral receptive speech processes. Laterality indices were calculated for left and right hemisphere late fields ∼150 to 400 milliseconds. The authors report that (1) in healthy adults, speech processes activated superior temporal regions bilaterally converging to a left-dominant pattern, (2) in four of six patients, this was reversed, with bilateral processing converging to a right-dominant pattern, and (3) in three of four of these patients, receptive and expressive language processes were laterally discordant. Results provide evidence that receptive and expressive language may have divergent hemispheric dominance. Right-sided receptive language dominance in epilepsy patients emphasizes the need to assess both receptive and expressive language. Findings indicate that it is critical to use multiple tasks tapping separable aspects of language function to provide sensitive and specific estimates of language localization in surgical patients.

    Boundary-layer receptivity to two-dimensional acoustic and vortical disturbances for hypersonic flows over two-dimensional and axi-symmetric geometries were numerically investigated. The role of bluntness, wall cooling, and pressure gradients on the receptivity and stability were analyzed and compared with the sharp nose cases. It was found that for flows over sharp nose geometries in adiabatic wall conditions the instability waves are generated in the leading-edge region and that the boundary layer is much more receptive to slow acoustic waves as compared to the fast waves. The computations confirmed the stabilizing effect of nose bluntness and the role of the entropy layer in the delay of boundary layer transition. The receptivity coefficients in flows over blunt bodies are orders of magnitude smaller than that for the sharp cone cases. Wall cooling stabilizes the first mode strongly and destabilizes the second mode. However, the receptivity coefficients are also much smaller compared to the adiabatic case. The adverse pressure gradients increased the unstable second mode regions.

    Providing reliable seasonal drought forecasts continues to pose a major challenge for scientists, end-users, and the water resources and agricultural communities. Precipitation (Prcp) forecasts beyond weather time scales are largely unreliable, so exploring new avenues to improve seasonal drought prediction is necessary to move towards applications and decision-making based on seasonal forecasts. A recent study has shown that evaporative demand (E0) anomaly forecasts from the Climate Forecast System Version 2 (CFSv2) are consistently more skillful than Prcp anomaly forecasts during drought events over CONUS, and E0 drought forecasts may be particularly useful during the growing season in the farming belts of the central and Midwestern CONUS. For this recent study, we used CFSv2 reforecasts to assess the skill of E0 and of its individual drivers (temperature, humidity, wind speed, and solar radiation), using the American Society for Civil Engineers Standardized Reference Evapotranspiration (ET0) Equation. Moderate skill was found in ET0, temperature, and humidity, with lesser skill in solar radiation, and no skill in wind. Therefore, forecasts of E0 based on models with no wind or solar radiation inputs may prove to be more skillful than the ASCE ET0. For this presentation we evaluate CFSv2 E0 reforecasts (1982-2009) from three different E0 models: (1) ASCE ET0; (2) Hargreaves and Samani (ET-HS), which is estimated from maximum and minimum temperature alone; and (3) Valiantzas (ET-V), which is a modified version of the Penman method for use when wind speed data are not available (or of poor quality) and is driven only by temperature, humidity, and solar radiation. The University of Idaho's gridded meteorological data (METDATA) were used as observations to evaluate CFSv2 and also to determine if ET0, ET-HS, and ET-V identify similar historical drought periods. We focus specifically on CFSv2 lead times of one, two, and three months, and season one forecasts; which are

    During the LHC Run-1, Grid resources in ATLAS have been managed by the PanDA and DQ2 systems. In order to meet the needs for the LHC Run-2, Prodsys2 and Rucio are used as the new ATLAS Workload and Data Management systems. The data are stored under various formats in ROOT files and end-user physicists have the choice to use either the ATHENA framework or directly ROOT. Within the ROOT data analysis framework it is possible to perform analysis of huge sets of ROOT files in parallel with PROOF on clusters of computers (usually organised in analysis facilities) or multi-core machines. In addition, PROOF-on-Demand (PoD) can be used to enable PROOF on top of an existing resource management system. In this work, we present the first performance obtained enabling PROOF-based analysis at CERN and in some of the Italian ATLAS Tier-2 sites within the new ATLAS workload system. Benchmark tests of data access with the httpd protocol, using also the httpd redirector, will be shown. We also present results on the startup latency tests using the new PROOF functionality of dynamic workers addition, which improves the performance of PoD using Grid resources. These new results will be compared with the expected improvements discussed in a previous work.
