Full Text Available Rapid economic growth in recent years has transformed our lifestyle to massively produce, consume, and dispose of products, especially for consumer electronics. This change has put great threat to our environment and caused natural resource depletion. Moreover, short product life cycles and quick replacements of consumer electronics create enormous electronic wastes (e-wastes. Without proper waste management, immense environmental damage is expected. In this empirical study, we notice that lots of valuable materials that can still be recycled from these used consumer electronics are left unused at home instead of being recycled at the appropriate time, which causes a low collection rate and a decrease in residual value for the used products. Therefore, it is important for the government and the recyclers to handle them efficiently by increasing the used product take-back rate. Our study develops an assessment model for customer value based on the idea of value engineering and the perspective of product life cycle. We also explore the relationship between product value and the total cost of ownership with an evaluation of their time variation, considering different usage modes for various consumer groups and different recycling award schemes (fixed and variable recycling awards. Proper take-back management is likely to create a win-win situation both for consumers and environmental protection. This study regards the notebook computer as an example to determine the optimal time for recycling laptops based on usage patterns and provides consumers a reference for when to replace their used product. The results from our modeling firstly clearly indicate that consumers with higher frequency of usage have shorter take back times and higher maximum consumer value. Secondly, a variable recycling award scheme with higher maximum consumer value is more practical than a fixed recycling award scheme.

Full Text Available Electronic mail and electronic communications systems are considered significant and effective tools of communication. One of the most widespread electronic communication tools is e - mail communication. In order to avoid misinterpretation of the report on the side of the recipient, it is need to pay attention to the writing of e - mail messages as well as to their content. With the continuous expansion of the use of electronic communication there have gradually developed certain rules of etiquette in electronic communications. The existing rules of the propriety ones are expressed in the term " etiqutte " and are not automatically applied in the new communications environment - media. For electronic communication, the new rules of etiquette have been stabilised into a term NETIQUETTE. The word netiquette was created by combining words NET (net and ETIKETA (a set of rules of social behavior and habits. Netiquette constitutes the rules of the behavior of users on a network. Although the netiquette is merely "an unwritten set of rules", their not using can be understood as a type of disrespect. Analysis of knowledge of domestic and foreign sources as well as results of a survey confirmed the justification of paying attention to the education of individuals in NETIQUETTE, irrespective of the degree of education.

Highlights: • We analyzed a data set of HDDs returned back to an e-waste collection site. • We studied factors that affect the storage behavior. • Consumer type, brand and size are among factors which affect the storage behavior. • Commercial consumers have stored computers more than household consumers. • Machine learning models were used to predict the storage behavior. - Abstract: Consumers often have a tendency to store their used, old or un-functional electronics for a period of time before they discard them and return them back to the waste stream. This behavior increases the obsolescence rate of used still-functional products leading to lower profitability that could be resulted out of End-of-Use (EOU) treatments such as reuse, upgrade, and refurbishment. These types of behaviors are influenced by several product and consumer-related factors such as consumers’ traits and lifestyles, technology evolution, product design features, product market value, and pro-environmental stimuli. Better understanding of different groups of consumers, their utilization and storage behavior and the connection of these behaviors with product design features helps Original Equipment Manufacturers (OEMs) and recycling and recovery industry to better overcome the challenges resulting from the undesirable storage of used products. This paper aims at providing insightful statistical analysis of Electronic Waste (e-waste) dynamic nature by studying the effects of design characteristics, brand and consumer type on the electronics usage time and end of use time-in-storage. A database consisting of 10,063 Hard Disk Drives (HDD) of used personal computers returned back to a remanufacturing facility located in Chicago, IL, USA during 2011–2013 has been selected as the base for this study.

Consumer demands: Major problems facing industry in a consumer-driven society.

Science.gov (United States)

Harrington, G

1994-01-01

Demand is driven by conventional market forces over much of the world among consumers with strong positive attitudes to meat as a nutritious, tasty and premium food; price in relation to income, availability, quality (including leanness) and relevance to life-style remain the dominant forces operating. But in the developed world, there are emerging concerns about how meat is produced, which are likely to have negative effects on demand, particularly that of the current younger generation, and which may well begin to affect Government policies towards the meat industry. The industry needs to establish strong information and education programmes, but also to examine its procedures to provide greater consumer assurance about practises and controls. Also the scientists and technologists serving the industry need to help it move towards sustainable lower input, less environmentally damaging systems, less reliance on drugs, stimulants and additives, sensitive exploitation of the new genetics and with more consideration for the animals involved.

Electronic communication in civil litigation

Directory of Open Access Journals (Sweden)

Salma Marija

2014-01-01

Full Text Available This paper looks into common European and national rules regulating electronic communication in legal matters. Such form of communication in legal matters expedites the procedure. It is also pointed out that electronic communication between the court and the parties to the proceedings, as well as third parties, is conducted through registries, regulated by special regulations, for filing written submissions of the parties and decisions of the court. Legislation regulating electronic communication is intended for litigation in commercial matters. European and national rules do not exclude the possibility of electronic communication in non-commercial litigation provided there is an express consent of the parties to such communication. Although steps towards digitalization have been taken in the Republic of Serbia, legislation regulating electronic service of documents, communication in civil litigation, is still missing. The Civil Procedure Law does not have a separate section regulating the electronic communication in legal matters. However, it cannot be said that the CPC does not set basic principles regulating this form of communication in legal matters.

2017-11-30

Visible-light-driven photochemistry has continued to attract heightened interest due to its capacity to efficiently harvest solar energy and its potential to solve the global energy crisis. Plasmonic nanostructures boast broadly tunable optical properties coupled with catalytically active surfaces that offer a unique opportunity for solar photochemistry. Resonant optical excitation of surface plasmons produces energetic hot electrons that can be collected to facilitate chemical reactions. This review sums up recent theoretical and experimental approaches for understanding the underlying photophysical processes in hot electron generation and discusses various electron-transfer models on both plasmonic metal nanostructures and plasmonic metal/semiconductor heterostructures. Following that are highlights of recent examples of plasmon-driven hot electron photochemical reactions within the context of both cases. The review concludes with a discussion about the remaining challenges in the field and future opportunities for addressing the low reaction efficiencies in hot-electron-induced photochemistry.

Exploring patients' health information communication practices with social network members as a foundation for consumer health IT design.

Valdez, Rupa Sheth; Brennan, Patricia Flatley

2015-05-01

There is a need to ensure that the growing number of consumer health information technologies designed to support patient engagement account for the larger social context in which health is managed. Basic research on how patients engage this larger social context is needed as a precursor to the development of patient-centered consumer health information technology (IT) solutions. The purpose of this study was to inform the broader design of consumer health IT by characterizing patients' existing health information communication practices with their social network members. This qualitative study took place between 2010 and 2012 in a Midwestern city. Eighteen patients with chronic conditions participated in a semi-structured interview that was analyzed using qualitative content analysis and descriptive statistics. Emphasis was placed on recruiting a sample representing diverse cultural groups and including participants of low socioeconomic status. Participants' social networks included a wide range of individuals, spanning biological relatives, divinities, and second-degree relationships. Participants' rationales for health information communication reflected seven themes: (1) characteristics and circumstances of the person, (2) characteristics and circumstances of the relationship, (3) structure and composition of the social network, (4) content of the message, (5) orientation of the goal, (6) dimensions of the context, and (7) adaptive practices. This study demonstrates that patients' health information communication practices are multidimensional, engaging individuals beyond formal and informal caregivers and driven by characteristics of their personal lives and larger social contexts in addition to their health problem. New models of consumer health IT must be created to better align with the realities of patients' communication routines. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Iacono, Teresa; Lyon, Katie; West, Denise

2011-10-01

Non-electronic communication aids provide one form of augmentative and alternative communication (AAC) for people with complex communication needs. The aim here was to explore non-electronic communication aids as one AAC option and research challenges. This aim was addressed by reviewing funding for the provision of AAC systems, data from an Australian pilot project providing non-electronic communication aids, an audit of aided AAC published studies (2000-2009), and discussion of the review literature. Combined, these sources indicate that although there is great demand for non-electronic communication aids, funding schemes, both in Australia and internationally, have focused on electronic communication aids. Such funding has usually failed to meet the total device costs and has not provided for adequate speech-language pathology support. Data from the pilot indicated the demand for non-electronic communication aids, and patterns suggest potential factors that govern the types selected. Despite the high demand for non-electronic aids, the research literature has tended to focus on electronic communication aids, including within intervention studies and addressing design features and long-term outcomes. Concerns about ensuring that AAC systems are chosen according to the assessed needs of individuals are discussed within the context of limitations in outcomes research and appropriate outcome measures.

DiFranco, Evelina; Bressi, Sara K; Salzer, Mark S

2006-01-01

People with serious mental illnesses experience increased rates of physical illnesses. Drop-in centers and psychosocial rehabilitation programs can serve as important settings for health promotion efforts, but such efforts should utilize communication strategies that are used by consumers and are perceived to be reliable. Focus groups involving 23 consumers at drop-in centers in Philadelphia were conducted to assess the perceived usefulness of health information from a variety of sources. Consumers especially liked getting information from other people, including health care professionals, friends, and family, and found the information to be reliable and useful. Print literature, the Internet, and a library had various limitations. Respondents were generally unfamiliar with community health fairs and related events. Consumers considered trustworthiness, proximity and availability, and the specificity and depth of information provided by a communication source when getting health information. Implications for health promotion efforts are discussed.

Swiss and Dutch "consumer-driven health care": ideal model or reality?

Science.gov (United States)

Okma, Kieke G H; Crivelli, Luca

2013-02-01

This article addresses three topics. First, it reports on the international interest in the health care reforms of Switzerland and The Netherlands in the 1990s and early 2000s that operate under the label "managed competition" or "consumer-driven health care." Second, the article reviews the behavior assumptions that make plausible the case for the model of "managed competition." Third, it analyze the actual reform experience of Switzerland and Holland to assess to what extent they confirm the validity of those assumptions. The article concludes that there is a triple gap in understanding of those topics: a gap between the theoretical model of managed competition and the reforms as implemented in both Switzerland and The Netherlands; second, a gap between the expectations of policy-makers and the results of the reforms, and third, a gap between reform outcomes and the observations of external commentators that have embraced the reforms as the ultimate success of "consumer-driven health care." The article concludes with a discussion of the implications of this "triple gap". Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Regulation of electron temperature gradient turbulence by zonal flows driven by trapped electron modes

Science.gov (United States)

Asahi, Y.; Ishizawa, A.; Watanabe, T.-H.; Tsutsui, H.; Tsuji-Iio, S.

2014-05-01

Turbulent transport caused by electron temperature gradient (ETG) modes was investigated by means of gyrokinetic simulations. It was found that the ETG turbulence can be regulated by meso-scale zonal flows driven by trapped electron modes (TEMs), which are excited with much smaller growth rates than those of ETG modes. The zonal flows of which radial wavelengths are in between the ion and the electron banana widths are not shielded by trapped ions nor electrons, and hence they are effectively driven by the TEMs. It was also shown that an E × B shearing rate of the TEM-driven zonal flows is larger than or comparable to the growth rates of long-wavelength ETG modes and TEMs, which make a main contribution to the turbulent transport before excitation of the zonal flows.

Curvature-driven instabilities in a hot-electron plasma: radial analysis

International Nuclear Information System (INIS)

Berk, H.L.; Van Dam, J.W.; Rosenbluth, M.N.; Spong, D.A.

1981-12-01

The theory of unfavorable curvature-driven instabilities is developed for a plasma interacting with a hot electron ring whose drift frequencies are larger than the growth rates predicted from conventional magnetohydrodynamic theory. A z-pinch model is used to emphasize the radial structure of the problem. Stability criteria are obtained for the five possible modes of instability: the conventional hot electron interchange, a high-frequency hot electron interchange (at frequencies larger than the ion cyclotron frequency), a compressional instability, a background pressure-driven interchange, and an interacting pressure-driven interchange

Science.gov (United States)

Eysenbach, G; Sa, ER; O'Connor, D; Jadad, A

1999-01-01

Introduction In an ongoing systematic review of the Cochrane Consumers & Communication Group we are compiling evidence on the impact of the Internet on public health. We include any "interactive health communication", i.e. any electronic interaction of an individual--consumer, patient, caregiver, or professional-with an electronic device or communication technology to access or transmit health information or to receive guidance on a health-related issue. Methods We will systematically search for and compile in an overview evidence for the effectiveness and impact of interactive communication for consumer health education. Evidence here means studies such as randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before and after (CBA) studies, interrupted time series (ITS) studies. Interventions to be compared against each other include a) consumers having been exposed to Internet-based health information against consumers having been exposed to traditional ways of health information, such as face-to-face interpersonal interactions, courses, printed material, self-help groups etc., and b) consumers having been exposed to Internet-based education against consumers having been exposed to Internet-based education using a different approach/method. As outcome measures we are especially looking for studies determining, a change of health related knowledge, attitude and behavior of participants, a change of health status of participants, the satisfaction of participants and health professionals and the change of relationship between patients and health professionals. Results Up to now, only one RCT has been found, highlighting the urgent need for more sound studies to determine the impact of the Internet on Public Health. Discussion The systematic review is still in progress and we invite authors of published and unpublished research addressing these questions to submit their work to us for inclusion into the analysis.

National energy use of consumer electronics in 1999

International Nuclear Information System (INIS)

Rosen, Karen; Meier, Alan; Zandelin, Stefan

2000-01-01

The major consumer electronics in U.S. homes accounted for nearly 7 percent of U.S. residential electricity consumption in 1999. We attribute more than half of this figure (3.6 percent) to televisions, videocassette recorders, and DVD players, and nearly one-third (1.8 percent) to audio products. Set-top boxes currently account for a relatively small fraction of residential electricity use (0.7 percent), but we expect this end-use to grow quickly with the proliferation of digital set-top boxes, which currently use 40 percent more energy per unit than the average TV set. In all, these consumer electronics plus telephone products consumed 75 TWh in the U.S. in 1999, half of which was consumed while the products were not in use. This energy use is expected to grow as products with new or advanced functionality hit the market

INFLUENCE OF MARKETING COMMUNICATIVE STRATEGIES ON CONSUMER BEHAVIOUR: A CASE OF THE HIGH-TECHNOLOGY MARKET OF UKRAINE

Directory of Open Access Journals (Sweden)

Victoria Zhurylo

2017-11-01

Full Text Available The purpose of the study is to research consumer behaviour types and to develop marketing strategies of communicative influence on the consumer in the high-technology goods market. Methodology. Marketing research in Ukrainian market of high-tech goods is conducted to define motivations of the consumers and the peculiarities of their market behaviour. The profiles of target customers are developed and the typology of consumer behaviour is formed, based on the reasons of purchasing of high-tech goods and on the level of consumer involvement in the purchasing process. Results showed that Highly Rational, Cautious, and Demonstrative behaviours can be observed in case of high consumer involvement in the buying process. Rationally-Confident, Comfortable, Adaptive behaviour can be observed in the case of low involvement. The peculiarities of communicative influence for each type of consumer behaviour in the market of high-tech goods are determined and the appropriate strategies of marketing communication are offered. Practical implementation. Strategies of communicative influence and communication sources depend on consumer behavioural types and the stage of the process of adopting innovations. In case of highly rational consumer behaviour, generic strategy, benefit strategy, and unique technical advantage strategies are recommended to be used as the main communicative strategies. Benefit strategy, unique technical advantage strategy, positioning strategy should be used in the case of rationally confident behaviour. The technology of intrusion, intimidation, positioning strategy, affective strategy, and resonance strategy should be used in the case of cautious consumer behaviour. Brand strategy should be used in the case of demonstrative consumer behaviour. The communicative strategies of product positioning and the strategy of resonance can be used in the case of comfortable consumer behaviour. Brand strategy is the main communicative strategy in the

This study examines changes over a 10-year period in consumer reports of communication with health care providers about direct-to-consumer advertised (DTCA) medications. Two rounds of survey data were collected in 2003 and 2012 using repeated cross-sectional procedures to examine consumer willingness to discuss DTCA medications, content and tone of those conversations, and attitudes about the advertisements. In total, 472 surveys were analyzed. Generally, we found physician-patient conversations, attitudes, and behaviors regarding DTCA have changed. Consumers in 2012 reported talking significantly less about the names of the advertised drug, comparing the advertised drug with their current medication, and sharing general information than consumers in 2003. Attitudes toward the advertisements were significantly more negative in 2012 compared to 2003. Of those who specifically asked for a prescription, the proportion of patients who received the prescription was significantly lower in 2012, despite research suggesting increased rates of prescriptions. These results are interpreted in light of previous research about the lack of research examining the actual communication between physicians and patients on this topic. Limitations of the study are provided along with directions for future research about DTCA and physician-patient communication.

Current status and future perspectives of electron interactions with molecules, clusters, surfaces, and interfaces [Workshop on Fundamental challenges in electron-driven chemistry; Workshop on Electron-driven processes: Scientific challenges and technological opportunities

Energy Technology Data Exchange (ETDEWEB)

Becker, Kurt H.; McCurdy, C. William; Orlando, Thomas M.; Rescigno, Thomas N.

2000-09-01

This report is based largely on presentations and discussions at two workshops and contributions from workshop participants. The workshop on Fundamental Challenges in Electron-Driven Chemistry was held in Berkeley, October 9-10, 1998, and addressed questions regarding theory, computation, and simulation. The workshop on Electron-Driven Processes: Scientific Challenges and Technological Opportunities was held at Stevens Institute of Technology, March 16-17, 2000, and focused largely on experiments. Electron-molecule and electron-atom collisions initiate and drive almost all the relevant chemical processes associated with radiation chemistry, environmental chemistry, stability of waste repositories, plasma-enhanced chemical vapor deposition, plasma processing of materials for microelectronic devices and other applications, and novel light sources for research purposes (e.g. excimer lamps in the extreme ultraviolet) and in everyday lighting applications. The life sciences are a rapidly advancing field where the important role of electron-driven processes is only now beginning to be recognized. Many of the applications of electron-initiated chemical processes require results in the near term. A large-scale, multidisciplinary and collaborative effort should be mounted to solve these problems in a timely way so that their solution will have the needed impact on the urgent questions of understanding the physico-chemical processes initiated and driven by electron interactions.

Geeslin, Matthew G; Gaskin, Cree M

2016-01-01

In most settings, radiologists maintain a high-throughput practice in which efficiency is crucial. The conversion from film-based to digital study interpretation and data storage launched the era of PACS-driven workflow, leading to significant gains in speed. The advent of electronic health records improved radiologists' access to patient data; however, many still find this aspect of workflow to be relatively cumbersome. Nevertheless, the ability to guide a diagnostic interpretation with clinical information, beyond that provided in the examination indication, can add significantly to the specificity of a radiologist's interpretation. Responsibilities of the radiologist include, but are not limited to, protocoling examinations, interpreting studies, chart review, peer review, writing notes, placing orders, and communicating with referring providers. Most of the aforementioned activities are not PACS-centric and require a login to one or more additional applications. Consolidation of these tasks for completion through a single interface can simplify workflow, save time, and potentially reduce the incidence of errors. Here, the authors describe diagnostic radiology workflow that leverages the electronic health record to significantly add to a radiologist's ability to be part of the health care team, provide relevant interpretations, and improve efficiency and quality.

Evolution and early evidence of the impact of consumer-driven health plans: from e-commerce venture to health savings accounts.

Science.gov (United States)

Parente, Stephen T; Feldman, Roger

2008-08-01

Using results from peer-reviewed empirical analyses we describe the development and impact of the consumer-driven health plan market over the last 5 years. The results of these analyses show that consumers are responding to the financial incentives of these new health insurance benefits. Although the results may not always be what the consumer-driven health plan developers intended, there is clear evidence of 'consumerism', where individuals act in a way that generally increases their access to healthcare or investments, if the opportunity is present. Just as Medicare Part D enrollment demonstrated consumers could identify differences in prescription drug plans and make rational choices, so too are prospective patients able to function as consumers in the medical marketplace when give the opportunity.

THE USE OF RELEVANT FACTORS FOR CONSUMERS IN DESIGNING A COMMUNICATIONAL MESSAGE

Directory of Open Access Journals (Sweden)

Olimpia OANCEA

2014-06-01

Full Text Available Today, organizations must adapt to the new realities of the environment in which they operate, and their efforts must be increasingly more oriented towards identifying the factors that influence consumer behavior, in particular economic, social and psychological aspects. When consumers are acting on incomplete information base, they assume automatically a risk for each purchasing decision. The size of the risk decreases depending on the quantity and relevance of information transmitted through communicational messages. Therefore, the aim of this paper is to highlight the factors that should be taken into account when designing a communicational message, so that this has to have the ability to change consumer attitudes and to keep constant interest to the products and / or services of a company.

Health care consumers' experiences of information communication technology--a summary of literature.

Akesson, Kerstin M; Saveman, Britt-Inger; Nilsson, Gunilla

2007-09-01

There is an increasing interest in reaching consumers directly through the Internet and different telecommunication systems. The most important contacts in health care will always be the face-to-face meetings, but the tools of health informatics can be seen as a means to an end, which is to provide the best possible health care. A variety of applications have been described in different references. To our knowledge there has been no review of a research-based state of the art in the field of consumers' experiences in using different applications in health informatics. According to the benefits in using information communication technology (ICT) as being cost-effective and timesaving it is of great importance to focus on and examine consumers' experiences. It is important that it is user friendly and regarded as valuable and useful. The aim of this study was to describe consumers' subjective experiences of using electronic resources with reference to health and illness. DESIGN AND/OR METHOD: A systematic literature search was performed in databases CINAHL, Medline and Cochrane, as well as a manual search. Retrieved references (n=14) were appraised according to their scientific structure and quality. A broad search was performed in order to find as many different applications as possible. Our primary intention was to identify existing references describing consumers' experiences with ICT. In spite of this broad search few references were found. Twelve references remained and three themes were identified: support and help, education and information, and telecommunication instead of on-site visiting. Consumers felt more confident and empowered, their knowledge increased and their health status improved due to the ICT resources. Lack of face-to-face meetings or privacy did not appear to be a problem. ICT can improve the nurse-patient relationship and augment well-being for consumers. More research is needed to measure consumers' experiences and factors that influence it

Medicine, market and communication: ethical considerations in regard to persuasive communication in direct-to-consumer genetic testing services.

Science.gov (United States)

Schaper, Manuel; Schicktanz, Silke

2018-06-05

Commercial genetic testing offered over the internet, known as direct-to-consumer genetic testing (DTC GT), currently is under ethical attack. A common critique aims at the limited validation of the tests as well as the risk of psycho-social stress or adaption of incorrect behavior by users triggered by misleading health information. Here, we examine in detail the specific role of advertising communication of DTC GT companies from a medical ethical perspective. Our argumentative analysis departs from the starting point that DTC GT operates at the intersection of two different contexts: medicine on the one hand and the market on the other. Both fields differ strongly with regard to their standards of communication practices and the underlying normative assumptions regarding autonomy and responsibility. Following a short review of the ethical contexts of medical and commercial communication, we provide case examples for persuasive messages of DTC GT websites and briefly analyze their design with a multi-modal approach to illustrate some of their problematic implications. We observe three main aspects in DTC GT advertising communication: (1) the use of material suggesting medical professional legitimacy as a trust-establishing tool, (2) the suggestion of empowerment as a benefit of using DTC GT services and (3) the narrative of responsibility as a persuasive appeal to a moral self-conception. While strengthening and respecting the autonomy of a patient is the focus in medical communication, specifically genetic counselling, persuasive communication is the normal mode in marketing of consumer goods, presuming an autonomous, rational, independent consumer. This creates tension in the context of DTC GT regarding the expectation and normative assessment of communication strategies. Our analysis can even the ground for a better understanding of ethical problems associated with intersections of medical and commercial communication and point to perspectives of analysis of

Mechanisms of Communicating Health Information Through Facebook: Implications for Consumer Health Information Technology Design.

2016-08-11

Consumer health information technology (IT) solutions are designed to support patient health management and have the ability to facilitate patients' health information communication with their social networks. However, there is a need for consumer health IT solutions to align with patients' health management preferences for increased adoption of the technology. It may be possible to gain an understanding of patients' needs for consumer health IT supporting their health information communication with social networks by explicating how they have adopted and adapted social networking sites, such as Facebook, for this purpose. Our aim was to characterize patients' use of all communication mechanisms within Facebook for health information communication to provide insight into how consumer health IT solutions may be better designed to meet patients' communication needs and preferences. This study analyzed data about Facebook communication mechanisms use from a larger, three-phase, sequential, mixed-methods study. We report here on the results of the study's first phase: qualitative interviews (N=25). Participants were over 18, used Facebook, were residents or citizens of the United States, spoke English, and had a diagnosis consistent with type 2 diabetes. Participants were recruited through Facebook groups and pages. Participant interviews were conducted via Skype or telephone between July and September 2014. Data analysis was grounded in qualitative content analysis and the initial coding framework was informed by the findings of a previous study. Participants' rationales for the use or disuse of a particular Facebook mechanism to communicate health information reflected six broad themes: (1) characteristics and circumstances of the person, (2) characteristics and circumstances of the relationship, (3) structure and composition of the social network, (4) content of the information, (5) communication purpose, and (6) attributes of the technology. The results of this

Full Text Available The models of integrated marketing communication have become today a very useful tool, that can provide companies a sustainable competitive advantage. The integrated marketing communication identifies with today's market dynamics and learn organizations how easy it can be to prosper in an environment where there are produced changes in an alarming way. In an economy with a strong competition character, organizations must capitalize integrated marketing communication in a way more efficiently, for to ensure the creation and maintenance of longterm relationships with current and potential customers. A product or a brand exist in the consumer's mind there not only because of experience with it, but also due to the medium and long term effects on that a message built on base the wishes, expectations or consumer preferences is transmitted simultaneously through as many tools of communication. Building and managing relationships with consumers can have a direct and positive effect on efficiency of the results of communication of a company. Changes in the business environment, along with technological innovation, increasing consumer sophistication and changes in marketing communications practices, have led organizations to seek to improve relationships with their consumers, and to strive to deliver consistent messages to all stakeholders - consumers, employees, company partners, the state, local governments, suppliers - across a wide range of integrated marketing communications channels.Therefore, the purpose of this article is to identify and analyze the main models of integrated marketing communication that can influence the consumer behaviour.

Coulomb-Driven Relativistic Electron Beam Compression.

2018-01-26

Coulomb interaction between charged particles is a well-known phenomenon in many areas of research. In general, the Coulomb repulsion force broadens the pulse width of an electron bunch and limits the temporal resolution of many scientific facilities such as ultrafast electron diffraction and x-ray free-electron lasers. Here we demonstrate a scheme that actually makes use of the Coulomb force to compress a relativistic electron beam. Furthermore, we show that the Coulomb-driven bunch compression process does not introduce additional timing jitter, which is in sharp contrast to the conventional radio-frequency buncher technique. Our work not only leads to enhanced temporal resolution in electron-beam-based ultrafast instruments that may provide new opportunities in probing material systems far from equilibrium, but also opens a promising direction for advanced beam manipulation through self-field interactions.

Delayed electron emission in strong-field driven tunnelling from a metallic nanotip in the multi-electron regime

Yanagisawa, Hirofumi; Schnepp, Sascha; Hafner, Christian; Hengsberger, Matthias; Kim, Dong Eon; Kling, Matthias F.; Landsman, Alexandra; Gallmann, Lukas; Osterwalder, Jürg

2016-01-01

Illuminating a nano-sized metallic tip with ultrashort laser pulses leads to the emission of electrons due to multiphoton excitations. As optical fields become stronger, tunnelling emission directly from the Fermi level becomes prevalent. This can generate coherent electron waves in vacuum leading to a variety of attosecond phenomena. Working at high emission currents where multi-electron effects are significant, we were able to characterize the transition from one regime to the other. Specifically, we found that the onset of laser-driven tunnelling emission is heralded by the appearance of a peculiar delayed emission channel. In this channel, the electrons emitted via laser-driven tunnelling emission are driven back into the metal, and some of the electrons reappear in the vacuum with some delay time after undergoing inelastic scattering and cascading processes inside the metal. Our understanding of these processes gives insights on attosecond tunnelling emission from solids and should prove useful in designing new types of pulsed electron sources. PMID:27786287

Full Text Available This study combines insights from market diffusion and consumer research to provide an inte-grated framework of mobile communications market in Japan. We base our analysis on data from company interview, focus group discussion and industry reports. Our findings indicate that technology push dominates in the early introduction and consumer needs pull in the maturing stage. Three implications for the marketing area are; first, user needs for mobile communications have evolved from basic mobility and functionality to include aesthetic and experiential benefits, second, innovations of product capabilities co-evolve with user needs, and lead to increases in mobile usage and product-user attachments, and third, in a saturated market, mobile consumption is premised on the utilitarian and hedonic values as perceived by the users. As mobile phone is a universal product, analysis of a saturated market such as Japan provides a deeper understanding of the evolution of technology and consumer in other markets.

Loop-driven graphical unitary group approach to the electron correlation problem, including configuration interaction energy gradients

International Nuclear Information System (INIS)

Brooks, B.R.

1979-09-01

The Graphical Unitary Group Approach (GUGA) was cast into an extraordinarily powerful form by restructuring the Hamiltonian in terms of loop types. This restructuring allows the adoption of the loop-driven formulation which illuminates vast numbers of previously unappreciated relationships between otherwise distinct Hamiltonian matrix elements. The theoretical/methodological contributions made here include the development of the loop-driven formula generation algorithm, a solution of the upper walk problem used to develop a loop breakdown algorithm, the restriction of configuration space employed to the multireference interacting space, and the restructuring of the Hamiltonian in terms of loop types. Several other developments are presented and discussed. Among these developments are the use of new segment coefficients, improvements in the loop-driven algorithm, implicit generation of loops wholly within the external space adapted within the framework of the loop-driven methodology, and comparisons of the diagonalization tape method to the direct method. It is also shown how it is possible to implement the GUGA method without the time-consuming full (m 5 ) four-index transformation. A particularly promising new direction presented here involves the use of the GUGA methodology to obtain one-electron and two-electron density matrices. Once these are known, analytical gradients (first derivatives) of the CI potential energy are easily obtained. Several test calculations are examined in detail to illustrate the unique features of the method. Also included is a calculation on the asymmetric 2 1 A' state of SO 2 with 23,613 configurations to demonstrate methods for the diagonalization of very large matrices on a minicomputer. 6 figures, 6 tables

Objective To identify research priorities of consumers and other stakeholders to inform Cochrane Reviews in ‘health communication and participation’ (including such concepts as patient experience, shared decision-making and health literacy). Setting International. Participants We included anyone with an interest in health communication and participation. Up to 151 participants (18–80 years; 117 female) across 12 countries took part, including 48 consumers (patients, carers, consumer representatives) and 75 professionals (health professionals, policymakers, researchers) (plus 25 people who identified as both). Design Survey. Methods We invited people to submit their research ideas via an online survey open for 4 weeks. Using inductive thematic analysis, we generated priority research topics, then classified these into broader themes. Results Participants submitted 200 research ideas, which we grouped into 21 priority topics. Key research priorities included: insufficient consumer involvement in research (19 responses), ‘official’ health information is contradictory and hard to understand (18 responses), communication/coordination breakdowns in health services (15 responses), health information provision a low priority for health professionals (15 responses), insufficient eliciting of patient preferences (14 responses), health services poorly understand/implement patient-centred care (14 responses), lack of holistic care impacting healthcare quality and safety (13 responses) and inadequate consumer involvement in service design (11 responses). These priorities encompassed acute and community health settings, with implications for policy and research. Priority populations of interest included people from diverse cultural and linguistic backgrounds, carers, and people with low educational attainment, or mental illness. Most frequently suggested interventions focused on training and cultural change activities for health services and health professionals

2016-05-01

The diabetes healthcare provider plays a key role in interpreting blood glucose trends, but few institutions have successfully integrated patient home glucose data in the electronic health record (EHR). Published implementations to date have required custom interfaces, which limit wide-scale replication. We piloted automated integration of continuous glucose monitor data in the EHR using widely available consumer technology for 10 pediatric patients with insulin-dependent diabetes. Establishment of a passive data communication bridge via a patient's/parent's smartphone enabled automated integration and analytics of patient device data within the EHR between scheduled clinic visits. It is feasible to utilize available consumer technology to assess and triage home diabetes device data within the EHR, and to engage patients/parents and improve healthcare provider workflow. © The Author 2016.

For this, uses the deductive approach and starts of the electronic contracting to discuss the legal protection of the consumer in light of the capturing and processing of personal data by the furnisher. Considering the absence of law about personal data, concludes that electronic contracting expands the consumer vulnerability, which requires the principles application of the Consumer Protection Code, adding the Internet Civil Mark in relation to the privacy protection.

Impact of communication on consumers' food choices.

Science.gov (United States)

Verbeke, Wim

2008-08-01

Consumers' food choices and dietary behaviour can be markedly affected by communication and information. Whether the provided information is processed by the receiver, and thus becomes likely to be effective, depends on numerous factors. The role of selected determinants such as uncertainty, knowledge, involvement, health-related motives and trust, as well as message content variables, are discussed in the present paper based on previous empirical studies. The different studies indicate that: uncertainty about meat quality and safety does not automatically result in more active information search; subjective knowledge about fish is a better predictor of fish consumption than objective knowledge; high subjective knowledge about functional foods as a result of a low trusted information source such as mass media advertising leads to a lower probability of adopting these foods in the diet. Also, evidence of the stronger impact of negative news as compared with messages promoting positive outcomes of food choices is discussed. Finally, three audience-segmentation studies based on consumers' involvement with fresh meat, individuals' health-related-motive orientations and their use of and trust in fish information sources are presented. A clear message from these studies is that communication and information provision strategies targeted to a specific audience's needs, interests or motives stand a higher likelihood of being attended to and processed by the receiving audience, and therefore also stand a higher chance of yielding their envisaged impact in terms of food choice and dietary behaviour.

Electricity consumption by battery-powered consumer electronics: A household-level survey

International Nuclear Information System (INIS)

McAllister, J. Andrew; Farrell, Alexander E.

2007-01-01

The rapid proliferation of battery-powered consumer electronics and their reliance on inefficient linear transformers has been suggested to be an important part of the rapid growth in 'miscellaneous' electricity consumption in recent years, but detailed data are scarce. We conducted a survey of 34 randomly selected households (HHs) in Northern California about the number, type, and usage of consumer electronics. We also measured the energy consumption of 85 typical consumer electronic devices through various parts of the charge cycle. These primary data were supplemented by national sales information for consumer electronics. Results indicate that typical HHs own 8.4 rechargeable devices, which have a total average demand of 12-17 W per HH. Statewide, this amounts to 160-220 MW of demand, with the peak occurring in the late evening, and about 1600 GWh per year. Only about 15% of this energy is used for battery charging, the rest is lost as waste heat during no-load and charge maintenance periods. Technical options to increase the efficiency of these devices, and the research and policy steps needed to realize these savings are discussed

To identify research priorities of consumers and other stakeholders to inform Cochrane Reviews in 'health communication and participation' (including such concepts as patient experience, shared decision-making and health literacy). International. We included anyone with an interest in health communication and participation. Up to 151 participants (18-80 years; 117 female) across 12 countries took part, including 48 consumers (patients, carers, consumer representatives) and 75 professionals (health professionals, policymakers, researchers) (plus 25 people who identified as both). Survey. We invited people to submit their research ideas via an online survey open for 4 weeks. Using inductive thematic analysis, we generated priority research topics, then classified these into broader themes. Participants submitted 200 research ideas, which we grouped into 21 priority topics. Key research priorities included: insufficient consumer involvement in research (19 responses), 'official' health information is contradictory and hard to understand (18 responses), communication/coordination breakdowns in health services (15 responses), health information provision a low priority for health professionals (15 responses), insufficient eliciting of patient preferences (14 responses), health services poorly understand/implement patient-centred care (14 responses), lack of holistic care impacting healthcare quality and safety (13 responses) and inadequate consumer involvement in service design (11 responses). These priorities encompassed acute and community health settings, with implications for policy and research. Priority populations of interest included people from diverse cultural and linguistic backgrounds, carers, and people with low educational attainment, or mental illness. Most frequently suggested interventions focused on training and cultural change activities for health services and health professionals. Consumers and other stakeholders want research addressing

Consumer-driven nutrient dynamics in freshwater ecosystems: from individuals to ecosystems.

The role of animals in modulating nutrient cycling [hereafter, consumer-driven nutrient dynamics (CND)] has been accepted as an important influence on both community structure and ecosystem function in aquatic systems. Yet there is great variability in the influence of CND across species and ecosystems, and the causes of this variation are not well understood. Here, we review and synthesize the mechanisms behind CND in fresh waters. We reviewed 131 articles on CND published between 1973 and 1 June 2015. The rate of new publications in CND has increased from 1.4 papers per year during 1973-2002 to 7.3 per year during 2003-2015. The majority of investigations are in North America with many concentrating on fish. More recent studies have focused on animal-mediated nutrient excretion rates relative to nutrient demand and indirect impacts (e.g. decomposition). We identified several mechanisms that influence CND across levels of biological organization. Factors affecting the stoichiometric plasticity of consumers, including body size, feeding history and ontogeny, play an important role in determining the impact of individual consumers on nutrient dynamics and underlie the stoichiometry of CND across time and space. The abiotic characteristics of an ecosystem affect the net impact of consumers on ecosystem processes by influencing consumer metabolic processes (e.g. consumption and excretion/egestion rates), non-CND supply of nutrients and ecosystem nutrient demand. Furthermore, the transformation and transport of elements by populations and communities of consumers also influences the flow of energy and nutrients across ecosystem boundaries. This review highlights that shifts in community composition or biomass of consumers and eco-evolutionary underpinnings can have strong effects on the functional role of consumers in ecosystem processes, yet these are relatively unexplored aspects of CND. Future research should evaluate the value of using species traits and abiotic

We elected to explore emerging consumer technologies that can be adopted to improve and facilitate image and data communication in medical and clinical environment. The wide adoption of new communication paradigm such as instant messaging, chatting and direct emailing can be integrated in specific applications. The increasing capacity of portable and hand held devices such as iPod music players offer an attractive alternative for data storage that exceeds the capabilities of traditional offline storage media such as CD or even DVD. We adapted medical image display and manipulation software called OSIRIX to integrate different innovative technologies facilitating the communication and data transfer between remote users. We integrated email and instant messaging features to the program allowing users to instantaneously email an image or a set of images that are displayed on the screen. Using iChat instant messaging application from Apple a user can share the content of his screen with a remote correspondent and communicate in real time using voice and video. To provide convenient mechanism for exchange of large data sets the program can store the data in DICOM format on CD or DVD, but was also extended to use the large storage capacity of iPod hard disks as well as Apple"s online storage service "dot Mac" that users can subscribe to benefit from scalable secure storage that accessible from anywhere on the internet. The adoption of these innovative technologies is likely to change the architecture of traditional picture archiving and communication systems and provide more flexible and efficient means of communication.

2018-02-23

Smartphones, tablets, and other personal electronic devices have become ubiquitous in Americans' daily lives. These devices are used by people throughout the day, including while preparing food. For example, a device may be used to look at recipes and therefore be touched multiple times during food preparation. Previous research has indicated that cell phones can harbor bacteria, including opportunistic human pathogens such as Staphylococcus and Klebsiella spp. This investigation was conducted with data from the 2016 Food Safety Survey (FSS) and from subsequent focus groups to determine the frequency with which consumers use personal electronic devices in the kitchen while preparing food, the types of devices used, and hand washing behaviors after handling these devices. The 2016 FSS is the seventh wave of a repeated cross-sectional survey conducted by the U.S. Food and Drug Administration in collaboration with the U.S. Department of Agriculture. The goal of the FSS is to evaluate U.S. adult consumer attitudes, behaviors, and knowledge about food safety. The FSS included 4,169 adults that were contacted using a dual-frame (land line and cell phone interviews) random-digit-dial sampling process. The personal electronics module was the first of three food safety topics discussed by each of eight consumer focus groups, which were convened in four U.S. cities in fall 2016. Results from the 2016 FSS revealed that of those individuals who use personal electronic devices while cooking, only about one third reported washing hands after touching the device and before continuing cooking. This proportion is significantly lower than that for self-reported hand washing behaviors after touching risky food products such as raw eggs, meat, chicken, or fish. Results from the focus groups highlight the varied usage of these devices during food preparation and the related strategies consumers are using to incorporate personal electric devices into their cooking routines.

1998-02-01

Using cognitive evaluation techniques, this study examines the effects of an electronic patient record and electronic mail on the interactions of health care providers. We find that the least structured communication methods are also the most heavily used: face-to-face, telephone, and electronic mail. Positive benefits of electronically-mediated interactions include improving communication, collaboration, and access to information to support decision-making. Negative factors include the potential for overloading clinicians with unwanted or unnecessary communications.

Direct-to-consumer (DTC) advertising saturates popular health magazines, communicating persuasive messages to readers that may influence attitudes and behaviors. This research used a two-prong approach to investigate the visual elements used in DTC advertising and their influence on consumers' understanding of a disease and its treatment options. An analysis was conducted of DTC advertisements (N = 62) from a population sample of Arthritis Today magazine, 2000-2010. Three panels of people with arthritis were used to validate the findings and discuss implications for health literacy. Pharmaceutical companies have an opportunity to communicate tailored messages to readers of niche publications and improve disease management.

It is increasingly recognized that some patients self-manage in the context of social networks rather than alone. Consumer health information technology (IT) designed to support socially embedded self-management must be responsive to patients' everyday communication practices. There is an opportunity to improve consumer health IT design by explicating how patients currently leverage social media to support health information communication. The objective of this study was to determine types of health information communication patterns that typify Facebook users with chronic health conditions to guide consumer health IT design. Seven hundred participants with type 2 diabetes were recruited through a commercial survey access panel. Cluster analysis was used to identify distinct approaches to health information communication both on and off Facebook. Analysis of variance (ANOVA) methods were used to identify demographic and behavioral differences among profiles. Secondary analysis of qualitative interviews ( n  = 25) and analysis of open-ended survey questions were conducted to understand participant rationales for each profile. Our analysis yielded 7 distinct health information communication profiles. Five of 7 profiles had consistent patterns both on and off Facebook, while the remaining 2 demonstrated distinct practices, with no health information communication on Facebook but some off Facebook. One profile was distinct from all others in both health information communication practices and demographic composition. Rationales for following specific health information communication practices were categorized under 6 themes: altruism, instrumental support, social support, privacy and stigma, convenience, and Facebook knowledge. Facebook has been widely adopted for health information communication; This study demonstrates that Facebook has been widely adopted for health information communication. It also shows that the ways in which patients communicate health

HE Dehua; LU Yaobin; ZHOU Deyi

2008-01-01

Electronic commerce is becoming increasingly important in business, but lack of intention to purchase has become a main barrier in the development of electronic commerce. Thus, effective measures are needed to promote consumers' intentions to purchase in online consumer to consumer (C2C) stores. This paper postulates that five factors, the perceived ease of use of the website, perceived usefulness of the website, vendor competence, introduction and recommendations of third parties, and vendors' attitude toward customers, influence consumers' intentions to purchase in online C2C stores and this intention directly leads to their action to purchase from online C2C stores. The structural equation modeling (SEM) method was used to analyze empirical data, supporting these hypotheses except for the effect of vendor competence.

Nominal research has examined sexual harassment and workplace violence against home care workers within consumer-driven home care models such as those offered in Oregon. This study examined home care workers' experiences of violence while providing care to consumer employers, the patients who hire and manage home care workers. Focus groups and interviews were conducted in Oregon with 83 home care workers, 99 Oregon Department of Human Services (DHS) employees, and 11 consumer employers. Home care workers reported incidents of workplace physical violence (44%), psychological abuse (65%), sexual harassment (41%), and sexual violence (14%). Further, three themes were identified that may increase the risk of workplace violence: (1) real and perceived barriers to reporting violence; (2) tolerance of violence; and (3) limited training to prevent violence. To ensure worker safety while maintaining quality care, safety policies and training for consumer employers, state DHS employees, and home care workers must be developed.

Household energy consumption and consumer electronics: The case of television

International Nuclear Information System (INIS)

Crosbie, Tracey

2008-01-01

In recent years, there has been a dramatic rise in the number of consumer electronics in households. These new technologies and the services that support them enable new highly energy intensive behaviours. Using in-depth interview data collected from 20 households in 2006, this paper explores these energy intensive behaviours, using the example of the use of televisions. In doing so, it illustrates how the design and marketing of consumer electronics, and the services which support them, actively encourage energy intensive behaviours and how householders are reconfiguring their homes and lifestyles to fit these behaviours. This latter point is significant because, as householders change their homes and daily lives to fit energy intensive consuming behaviours, it will become increasingly difficult to encourage people to reduce their household energy consumption. This paper concludes with the implications of the research findings for policies designed to reduce household energy consumption

Health communication and consumer behavior on meat in Belgium: from BSE until dioxin.

Science.gov (United States)

Verbeke, W; Viaene, J; Guiot, O

1999-01-01

This article focuses on the impact of mass media meat-health information on consumer perception, attitude, and behavior toward fresh meat in Belgium. In a situation similar to that which occurred in most other European countries, Belgian fresh meat consumption fell considerably during 1995-1999. A multitude of messages linking meat consumption to human health risks were reported by mass media. Bovine Spongiform Encephalopathy (BSE) since 1996 and dioxin in 1999 constituted the major issues. Empirical research, conducted in April 1998, revealed the tremendous negative impact of mass media coverage of meat-health issues on consumer risk perception, health concern, and attitude and behavior toward fresh meat. Oppositely, personal communication through butchers had only a small effect on consumer decision-making in this era dominated by alarming meat-health press. Implications are threefold. First, mass media should be aware of its social responsibilities, which include spreading reliable and correct information to the society. This is especially the case as human health risks are involved. Second, the meat industry urgently needs to reorient itself toward quality, safety, and transparency. Finally, future communication dealing with similar crises situations requires cooperation across the meat chain, government, and those who are responsible for public health promotion and communication.

Electron heating of voltage-driven and matched dual frequency discharges

International Nuclear Information System (INIS)

Lieberman, M A; Lichtenberg, A J

2010-01-01

In a dual frequency capacitive sheath, a high frequency uniform sheath motion is coupled with a low frequency Child law sheath motion. For current-driven high and low frequency sheaths, the high frequency sheath motion generates most of the ohmic and stochastic heating of the discharge electrons. The low frequency motion, in addition to its primary purpose of establishing the ion bombarding energy, also increases the heating by widening the sheath width and transporting the oscillating electrons to regions of lower plasma density, and hence higher sheath velocity. In this work, we show that for voltage-driven high and low frequency sheaths, increasing the low frequency voltage reduces the heating, due to the reduced high frequency current that flows through the sheath under voltage-driven conditions. We determine the dependence of the heating on various parameters and compare the results with the current-driven case. Particle-in-cell simulations are used to confirm this result. Discharges generally employ a matching network to maximize the power transmitted to the plasma. We obtain analytic expressions for the effect of the low frequency source under matched conditions and, again, find that the low frequency source reduces the heating.

Redesigning a collection system for 'small' consumer electronics

International Nuclear Information System (INIS)

Melissen, Frans W.

2006-01-01

This paper establishes that the collection system within the recycling scheme for consumer electronics in the Netherlands has not been entirely successful in convincing consumers to hand in their used appliances by means of dedicated collection routes. Particularly regarding small appliances, consumers are persisting in their habit of discarding their appliances by means of the refuse bag/bin for regular household waste. Therefore, the current collection system has been unable to direct consumer behavior in the desired direction. Consequently, the layout of the current system is reviewed and redesigned in order to tackle this problem. This design effort applies the Triad model (behavioral model) in the analysis stage and the Morphological Chart method (design tool) in the synthesis stage, and results in a concrete proposal for a new system. Finally, the applicability of this design approach beyond the specific circumstances of the case study presented in this paper is discussed. This case represents only one example of the broader, worldwide challenge to design appropriate collection systems to direct consumer behavior in desired directions. It is argued that the approach presented in this paper could be a valuable contribution to research dealing with this challenge

Saturation mechanism of decaying ion temperature gradient driven turbulence with kinetic electrons

International Nuclear Information System (INIS)

Idomura, Yasuhiro

2016-01-01

We present full-f gyrokinetic simulations of the ion temperature gradient driven (ITG) turbulence including kinetic electrons. By comparing decaying ITG turbulence simulations with adiabatic and kinetic electron models, an impact of kinetic electrons on the ITG turbulence is investigated. It is found that significant electron transport occurs even in the ITG turbulence, and both ion and electron temperature profiles are relaxed. In steady states, both cases show upshifts of nonlinear critical ion temperature gradients from linear ones, while their saturation mechanisms are qualitatively different. In the adiabatic electron case, the ITG mode is stabilized by turbulence driven zonal flows. On the other hand, in the kinetic electron case, passing electrons transport shows fine resonant structures at mode rational surfaces, which generate corrugated density profiles. Such corrugated density profiles lead to fine radial electric fields following the neoclassical force balance relation. The resulting E × B shearing rate greatly exceeds the linear growth rate of the ITG mode. (author)

Full Text Available The objective of the present empirical study is to determine the factors influencing the tourism consumer satisfaction, as it results from the evaluations posted on virtual platforms. The communication platform chosen as study is the Romanian website Amfostacolo.ro. In this case, the travel consumer satisfaction is expressed by the score of the ratings posted on the virtual platform Amfostacolo.ro and the decision to recommend or not the unit / destination. Considering the peculiarities of the communication platform studied, the elements influencing the score indicating satisfaction there can be identified as components of tourism supply and the characteristics of the reviewer. Data processing has been carried out with ordinary least squares (OLS, structural equation modeling (confirmatory factor analysis, path analysis, cluster analisys and polytomous logistic regression. The results broadly confirm the hypotheses, namely that: the type of stay and the age of the reviewer influence the satisfaction of the consumer more than the destination and number of stars of the accommodation, the age group of the reviewer influences the destination yet it is uncertain about the influence of the variables related to the holiday (the type of stay and the number of stars of the accommodation, the meal service influences more than other attributes the consumer satisfaction and the recommendation of the reviewer is influenced by the characteristics related to his person and the holiday consumed.

Commentary: Lost in translation? How electronic health records structure communication, relationships, and meaning.

Science.gov (United States)

Lown, Beth A; Rodriguez, Dayron

2012-04-01

The media through which we communicate shape how we think, how we act, and who we are. Electronic health records (EHRs) may promote more effective, efficient, coordinated, safer care. Research is emerging, but more is needed to assess the effect of EHRs on communication, relationships, patients' trust, adherence, and health outcomes. The authors posit that EHRs introduce a "third party" into exam room interactions that competes with the patient for clinicians' attention, affects clinicians' capacity to be fully present, and alters the nature of communication, relationships, and physicians' sense of professional role. Screen-driven communication inhibits patients' narratives and diminishes clinicians' responses to patients' cues about psychosocial issues and emotional concerns. Students, trainees, and clinicians can, however, learn to integrate EHRs into triadic exam room interactions to facilitate information sharing and shared decision making.Student exposure to EHRs is currently limited. Educators and researchers should implement curricula and assessment tools to help learners integrate EHRs into clinical interactions in ways that foster, rather than diminish, communication and relationships. Further, educators must prioritize the teaching and modeling of self-awareness and self-calibration, mindful presence, and compassion within such curricula to prevent these important qualities and skills from being lost in translation in the digital era.

A multi-frequency approach to free electron lasers driven by short electron bunches

International Nuclear Information System (INIS)

Piovella, Nicola

1997-01-01

A multi-frequency model for free electron lasers (FELs), based on the Fourier decomposition of the radiation field coupled with the beam electrons, is discussed. We show that the multi-frequency approach allows for an accurate description of the evolution of the radiation spectrum, also when the FEL is driven by short electron bunches, of arbitrary longitudinal profile. We derive from the multi-frequency model, by averaging over one radiation period, the usual FEL equations modelling the slippage between radiation and particles and describing the super-radiant regime in high-gain FELs. As an example of application of the multi-frequency model, we discuss the coherent spontaneous emission (CSE) from short electron bunches

Compression-Driven Enhancement of Electronic Correlations in Simple Alkali Metals

Fabbris, Gilberto; Lim, Jinhyuk; Veiga, Larissa; Haskel, Daniel; Schilling, James

2015-03-01

Alkali metals are the best realization of the nearly free electron model. This scenario appears to change dramatically as the alkalis are subjected to extreme pressure, leading to unexpected properties such as the departure from metallic behavior in Li and Na, and the occurrence of remarkable low-symmetry crystal structures in all alkalis. Although the mechanism behind these phase transitions is currently under debate, these are believed to be electronically driven. In this study the high-pressure electronic and structural ground state of Rb and Cs was investigated through low temperature XANES and XRD measurements combined with ab initio calculations. The results indicate that the pressure-induced localization of the conduction band triggers a Peierls-like mechanism, inducing the low symmetry phases. This localization process is evident by the pressure-driven increase in the number of d electrons, which takes place through strong spd hybridization. These experimental results indicate that compression turns the heavy alkali metals into strongly correlated electron systems. Work at Argonne was supported by DOE No. DE-AC02-06CH11357.

This paper analyzes the way risk management measures (RMMs) for consumer products have been used to date in authority and industry risk assessments. A working concept for consumer product RMMs is developed, aimed at controlling, limiting or avoiding exposures, and helping to insure the safe use (or handling) of a substance as part of a consumer product. Particular focus is placed on new requirements introduced by REACH (registration, evaluation, and authorization of chemicals). A RMMs categorization approach is also developed, dividing consumer product RMMs into those that are product integrated and those that are communicated to consumers. For each of these categories, RMMs for normal use, accidental use or misuse need to be distinguished. The level of detail for documenting, assessing and communicating RMMs across supply chains can vary, depending on the type of the assessment (tiered approach). Information on RMMs was collected from published sources to demonstrate that a taxonomical approach using standard descriptors for RMMs libraries is needed for effective information exchange across supply chains.

Harnessing social networks along with consumer-driven electronic communication technologies to identify and engage members of 'hard-to-reach' populations: a methodological case report.

Rock, Melanie J

2010-01-20

Sampling in the absence of accurate or comprehensive information routinely poses logistical, ethical, and resource allocation challenges in social science, clinical, epidemiological, health service and population health research. These challenges are compounded if few members of a target population know each other or regularly interact. This paper reports on the sampling methods adopted in ethnographic case study research with a 'hard-to-reach' population. To identify and engage a small yet diverse sample of people who met an unusual set of criteria (i.e., pet owners who had been treating cats or dogs for diabetes), four sampling strategies were used. First, copies of a recruitment letter were posted in pet-friendly places. Second, information about the study was diffused throughout the study period via word of mouth. Third, the lead investigator personally sent the recruitment letter via email to a pet owner, who then circulated the information to others, and so on. Fourth, veterinarians were enlisted to refer people who had diabetic pets. The second, third and fourth strategies rely on social networks and represent forms of chain referral sampling. Chain referral sampling via email proved to be the most efficient and effective, yielding a small yet diverse group of respondents within one month, and at negligible cost. The widespread popularity of electronic communication technologies offers new methodological opportunities for researchers seeking to recruit from hard-to-reach populations.

This article aims to identify the taxonomy of readership categories that reflect the complexity of how health care consumers interact with DTCA, with particular focus on individuals' perceptions of print DTCA in popular magazines. Respondent-driven sampling was used to recruit 18 male and female magazine readers and 18 male and female prescription medication users aged 18–71 years. Semi-structured, in-depth interviews with consumers about their attentiveness, motivations, perceived value, and behavioral responses to DTCA were conducted. The analyses were guided by principles of grounded theory analysis; four categories that vary in consumers' attentiveness, motivations, perceived value, and behavioral responses to DTCA were identified. Two categories – the lay physician and the informed shopper – see value in information from DTCA and are likely to seek medical care based on the information. One category – the voyeur – reads DTCA, but is not likely to approach a clinician regarding advertised information. The fourth category – the evader – ignores DTCA and is not likely to approach a clinician with DTCA information. Responses to DTCA vary considerably among consumers, and physicians should view patients' understanding and response to DTCA within the context of their health-related needs. Patients' comments

Energy use of U.S. consumer electronics at the end of the 20th century

International Nuclear Information System (INIS)

Rosen, Karen; Meier, Alan

2000-01-01

The major consumer electronics in U.S. homes accounted for over 10 percent of U.S. residential electricity consumption, which is comparable to the electricity consumed by refrigerators or lighting. We attribute 3.6 percent to video products, 3.3 percent to home office equipment, and 1.8 percent to audio products. Televisions use more energy than any other single product category, but computer energy use now ranks second and is likely to continue growing. In all, consumer electronics consumed 110 THw in the U.S. in 1999, over 60 percent of which was consumed while the products were not in use

Electronic communication improves access, but barriers to its widespread adoption remain.

Bishop, Tara F; Press, Matthew J; Mendelsohn, Jayme L; Casalino, Lawrence P

2013-08-01

Because electronic communication is quick, convenient, and inexpensive for most patients, care that is truly patient centered should promote the use of such communication between patients and providers, even using it as a substitute for office visits when clinically appropriate. Despite the potential benefits of electronic communication, fewer than 7 percent of providers used it in 2008. To learn from the experiences of providers that have widely incorporated electronic communication into patient care, we interviewed leaders of twenty-one medical groups that use it extensively with patients. We also interviewed staff in six of those groups. Electronic communication was widely perceived to be a safe, effective, and efficient means of communication that improves patient satisfaction and saves patients time but that increases the volume of physician work unless office visits are reduced. Practice redesign and new payment methods are likely necessary for electronic communication to be more widely used in patient care.

Carrillo, Richard R; Ros, Eduardo; Barbour, Boris; Boucheny, Christian; Coenen, Olivier

2007-02-01

Most neural communication and processing tasks are driven by spikes. This has enabled the application of the event-driven simulation schemes. However the simulation of spiking neural networks based on complex models that cannot be simplified to analytical expressions (requiring numerical calculation) is very time consuming. Here we describe briefly an event-driven simulation scheme that uses pre-calculated table-based neuron characterizations to avoid numerical calculations during a network simulation, allowing the simulation of large-scale neural systems. More concretely we explain how electrical coupling can be simulated efficiently within this computation scheme, reproducing synchronization processes observed in detailed simulations of neural populations.

Clarke, Brendan P.; MacDonald, Kevin F.; Zheludev, Nikolay I.

2018-01-01

We report on a free-electron-driven light source with a controllable direction of emission. The source comprises a microscopic array of plasmonic surface-relief holographic domains, each tailored to direct electron-induced light emission at a selected wavelength into a collimated beam in a prescribed direction. The direction-division multiplexed source is tested by driving it with the 30 kV electron beam of a scanning electron microscope: light emission, at a wavelength of 800 nm in the present case, is switched among different output angles by micron-scale repositioning of the electron injection point among domains. Such sources, with directional switching/tuning possible at picosecond timescales, may be applied to field-emission and surface-conduction electron-emission display technologies, optical multiplexing, and charged-particle-beam position metrology.

Radial structure of curvature-driven instabilities in a hot-electron plasma

International Nuclear Information System (INIS)

Spong, D.A.; Berk, H.L.; Van Dam, J.W.

1984-01-01

A nonlocal analysis of curvature-driven instabilities for a hot-electron ring interacting with a warm background plasma has been made. Four different instability modes characteristic of hot-electron plasmas have been examined: the high-frequency hot-electron interchange (at frequencies larger than the ion-cyclotron frequency), the compressional Alfven instability, the interacting background pressure-driven interchange, and the conventional hot-electron interchange (at frequencies below the ion-cyclotron frequency). The decoupling condition between core and hot-electron plasmas has also been examined, and its influence on the background and hot-electron interchange stability boundaries has been studied. The assumed equilibrium plasma profiles and resulting radial mode structure differ somewhat from those used in previous local analytic estimates; however, when the analysis is calibrated to the appropriate effective radial wavelength of the nonlocal calculation, reasonable agreement is obtained. Comparison with recent experimental measurements indicates that certain of these modes may play a role in establishing operating boundaries for the ELMO Bumpy Torus-Scale (EBT-S) experiment. The calculations given here indicate the necessity of having core plasma outside the ring to prevent the destabilizing wave resonance of the precessional mode with a cold plasma

Simulation based decision support for strategic communication and marketing management concerning the consumer introduction of smart energy meters

Directory of Open Access Journals (Sweden)

Jeroen STRAGIER

2013-07-01

Full Text Available Communication and marketing professionals make strategic decisions in highly complex and dynamic contexts. These decisions are highly uncertain on the outcome and process level when, for example, consumer behaviour is at stake. Decision support systems can provide insights in these levels of uncertainty and the professional process of decision making. However, literature describing decision support tools for strategic communication and marketing management that provide clear insights in uncertainty levels is lacking. This study therefore aims at developing a consumer behaviour simulation module as an important element of such a future decision support tool. The consumer behaviour simulation we propose in this paper is based on data collected from a survey among 386 households with which a behavioural change model was calibrated. We show how various decision scenarios for strategic communication and marketing challenges can be explored and how such a simulation based decision support system can facilitate strategic communication and marketing management concerning the introduction of a smart energy meter.

2016-06-01

This pilot study investigated nurse practitioner students' communication skills when utilizing the electronic health record during history taking. The nurse practitioner students (n = 16) were videotaped utilizing the electronic health record while taking health histories with standardized patients. The students were videotaped during two separate sessions during one semester. Two observers recorded the time spent (1) typing and talking, (2) typing only, and (3) looking at the computer without talking. Total history taking time, computer placement, and communication skills were also recorded. During the formative session, mean history taking time was 11.4 minutes, with 3.5 minutes engaged with the computer (30.6% of visit). During the evaluative session, mean history taking time was 12.4 minutes, with 2.95 minutes engaged with the computer (24% of visit). The percentage of time individuals spent changed over the two visits: typing and talking, -3.1% (P = .3); typing only, +12.8% (P = .038); and looking at the computer, -9.6% (P = .039). This study demonstrated that time spent engaged with the computer during a patient encounter does decrease with student practice and education. Therefore, students benefit from instruction on electronic health record-specific communication skills, and use of a simple mnemonic to reinforce this is suggested.

Lighnting detection and tracking with consumer electronics

Lightning data is not only important for environment and weather monitoring but also for safety purposes. The AS3935 Franklin Lightning Sensor (AMS, Unterpremstaetten, Austria) is a lightning sensor developed for inclusion in consumer electronics such as watches and mobile phones. The AS3935 is small (4mmx4mm) and relatively cost effective (Eu 5). The downside is that only rough distance estimates are provided, as average power is assumed for every lightning strike. To be able to track lightning, a network of devices that monitor and keep track of occurrences of lightning strikes was developed. A communication interface was established between the sensors, a data logging circuit and a microcontroller. The digital outputs of the lightning sensor and data from a GPS are processed by the microcontroller and logged onto an SD card. The interface program enables sampling parameters such as distance from the lightning strike, time of strike occurrence and geographical location of the device. For archiving and analysis purposes, the data can be transferred from the SD card to a PC and results displayed using a graphical user interface program. Data gathered shows that the device can track the frequency and movement of lightning strikes in an area. The device has many advantages as compared to other lightning sensor stations in terms of huge memory, lower power consumption, small size, greater portability and lower cost. The devices were used in a network around Nairobi, Kenya. Through multi-lateration, lightning strikes could be located with a RMSE of 2 km or better.

Data-Driven Handover Optimization in Next Generation Mobile Communication Networks

Po-Chiang Lin

2016-01-01

Full Text Available Network densification is regarded as one of the important ingredients to increase capacity for next generation mobile communication networks. However, it also leads to mobility problems since users are more likely to hand over to another cell in dense or even ultradense mobile communication networks. Therefore, supporting seamless and robust connectivity through such networks becomes a very important issue. In this paper, we investigate handover (HO optimization in next generation mobile communication networks. We propose a data-driven handover optimization (DHO approach, which aims to mitigate mobility problems including too-late HO, too-early HO, HO to wrong cell, ping-pong HO, and unnecessary HO. The key performance indicator (KPI is defined as the weighted average of the ratios of these mobility problems. The DHO approach collects data from the mobile communication measurement results and provides a model to estimate the relationship between the KPI and features from the collected dataset. Based on the model, the handover parameters, including the handover margin and time-to-trigger, are optimized to minimize the KPI. Simulation results show that the proposed DHO approach could effectively mitigate mobility problems.

Reis, D

2003-01-01

The Gun Test Facility (GTF) at the Stanford Linear Accelerator Center was constructed to develop an appropriate electron beam suitable for driving a short wavelength free electron laser (FEL) such as the proposed Linac Coherent Light Source (LCLS). For operation at a wavelength of 1.5 (angstrom), the LCLS requires an electron injector that can produce an electron beam with approximately 1 pi mm-mrad normalized rms emittance with at least 1 nC of charge in a 10 ps or shorter bunch. The GTF consists of a photocathode rf gun, emittance-compensation solenoid, 3 m linear accelerator (linac), drive laser, and diagnostics to measure the beam. The rf gun is a symmetrized 1.6 cell, s-band high gradient, room temperature, photocathode structure. Simulations show that this gun when driven by a temporally and spatially shaped drive laser, appropriately focused with the solenoid, and further accelerated in linac can produce a beam that meets the LCLS requirements. This thesis describes the initial characterization of the ...

New regulations require living kidney donor (LKD) follow-up for 2 years, but donor retention remains poor. Electronic communication (eg, text messaging and e-mail) might improve donor retention. To explore the possible impact of electronic communication, we recruited LKDs to participate in an exploratory study of communication via telephone, e-mail, or text messaging postdonation; communication through this study was purely optional and did not replace standard follow-up. Of 69 LKDs recruited, 3% requested telephone call, 52% e-mail, and 45% text messaging. Telephone response rate was 0%; these LKDs were subsequently excluded from analysis. Overall response rates with e-mail or text messaging at 1 week, 1 month, 6 months, 1 year, and 2 years were 94%, 87%, 81%, 72%, and 72%. Lower response rates were seen in African Americans, even after adjusting for age, sex, and contact method (incidence rate ratio (IRR) nonresponse 2.07 5.81 16.36 , P = .001). Text messaging had higher response rates than e-mail (IRR nonresponse 0.11 0.28 0.71 , P = .007). Rates of nonresponse were similar by sex (IRR 0.68, P = .4) and age (IRR 1.00, P > .9). In summary, LKDs strongly preferred electronic messaging over telephone and were highly responsive 2 years postdonation, even in this nonrequired, nonincentivized exploratory research study. These electronic communication tools can be automated and may improve regulatory compliance and postdonation care. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Information and communication technologies are widely used in health and social care settings to replace previous means of record keeping, assessment and communication. Commentary on the strengths and weaknesses of such systems abound, thus it is useful to examine how they are used in practice. This article draws on findings from two separate studies, conducted between 2005 and 2007, which examined how child health and welfare professionals use electronic documents in Finland and England. Known respectively as Miranda and CAF, these systems are different in terms of structure and function but in their everyday use common features are identified, notably the continued use of and reliance on non-electronic means of communication. Based on interviews with professionals, three forms of non-electronic communication are described: alternative records, phone calls and letters, which facilitate the sharing of the electronic record. Finally, the electronic documents are further analysed as potential boundary objects which aim to create common understanding between sites and professionals. Copyright © 2012 Elsevier Ltd.

Robust technology infrastructure is needed to enable learning health care systems to improve quality, access, and cost. Such infrastructure relies on the trust and confidence of individuals to share their health data for healthcare and research. Few studies have addressed consumers' views on electronic data sharing and fewer still have explored the dual purposes of healthcare and research together. The objective of the study is to explore factors that affect consumers' willingness to share electronic health information for healthcare and research. This study involved a random-digit dial telephone survey of 800 adult Californians conducted in English and Spanish. Logistic regression was performed using backward selection to test for significant (p-value ≤ 0.05) associations of each explanatory variable with the outcome variable. The odds of consent for electronic data sharing for healthcare decreased as Likert scale ratings for EHR impact on privacy worsened, odds ratio (OR) = 0.74, 95% CI [0.60, 0.90]; security, OR = 0.80, 95% CI [0.66, 0.98]; and quality, OR = 0.59, 95% CI [0.46-0.75]. The odds of consent for sharing for research was greater for those who think EHR will improve research quality, OR = 11.26, 95% CI [4.13, 30.73]; those who value research benefit over privacy OR = 2.72, 95% CI [1.55, 4.78]; and those who value control over research benefit OR = 0.49, 95% CI [0.26, 0.94]. Consumers' choices about electronically sharing health information are affected by their attitudes toward EHRs as well as beliefs about research benefit and individual control. Design of person-centered interventions utilizing electronically collected health information, and policies regarding data sharing should address these values of importance to people. Understanding of these perspectives is critical for leveraging health data to support learning health care systems.

High-brightness electron source driven by laser

International Nuclear Information System (INIS)

Zhao Kui; Geng Rongli; Wang Lifang

1996-01-01

A DC high-brightness laser driven by photo emissive electron gun is being developed at Beijing University, in order to produce 50∼100 ps electron bunches of high quality. The gun consists of a photocathode preparation chamber and a DC acceleration cavity. Different ways of fabricating photocathode, such as chemical vapor deposition, ion beam implantation and ion beam enhanced deposition, can be adopted. The acceleration gap is designed with the aid of simulation codes EGUN and POISSON. 100 kV DC high voltage is fed to the anode through a careful designed ceramic insulator. The laser system is a mode locked Nd-YAG oscillator proceeded by an amplifier at 10 Hz repetition rate, which can deliver three different wavelength (1064/532/266 nm). The combination of a superconducting cavity with the photocathode preparation chamber is discussed

Laser-driven injector of electrons for IOTA

Science.gov (United States)

Romanov, Aleksandr

2017-03-01

Fermilab is developing the Integrable Optics Test Accelerator (IOTA) ring for experiments on nonlinear integrable optics. The machine will operate with either electron beams of 150 MeV or proton beams of 2.5 MeV energies, respectively. The stability of integrable optics depends critically on the precision of the magnetic lattice, which demands the use of beam-based lattice measurements for optics correction. In the proton mode, the low-energy proton beam does not represent a good probe for this application; hence we consider the use of a low-intensity reverse-injected electron beam of matched momentum (70 MeV). Such an injector could be implemented with the use of laser-driven acceleration techniques. This report presents the consideration for a laser-plasma injector for IOTA and discusses the requirements determined by the ring design.

Laser-driven-wakefield electron accelerators have shown electron beams with energies of up to 1 GeV from a centimeter-scale plasma accelerator. In order to achieve higher electron energies, these acceleration distances need to be increased. This can be realized with a discharge capillary. However, a discharge typically introduces instabilities on both pointing and energy of the generated electrons. In order to improve the stability, we demonstrate a preliminary test of a modified discharge which includes a pre-pulse circuit before the firing of the main pulse. We also show gas density shaping by a laser- machined nozzle which should be able to make a more precise injection in the capillary accelerator thus reducing the energy instability.

This paper provides a comparison of the performance of an electron accelerator-driven experiment, under discussion within the Reactor Accelerator Coupling Experiments (RACE) Project, being conducted within the U.S. Dept. of Energy's Advanced Fuel Cycle Initiative (AFCI), and of the proton-driven experiment TRADE (TRIGA Accelerator Driven Experiment) originally planned at ENEA-Casaccia in Italy. Both experiments foresee the coupling to sub-critical TRIGA core configurations, and are aimed to investigate the relevant kinetic and dynamic accelerator-driven systems (ADS) core behavior characteristics in the presence of thermal reactivity feedback effects. TRADE was based on the coupling of an upgraded proton cyclotron, producing neutrons via spallation reactions on a tantalum (Ta) target, with the core driven at a maximum power around 200 kW. RACE is based on the coupling of an Electron Linac accelerator, producing neutrons via photoneutron reactions on a tungsten-copper (W-Cu) or uranium (U) target, with the core driven at a maximum power around 50 kW. The paper is focused on analysis of expected dynamic power response of the RACE core following reactivity and/or source transients. TRADE and RACE target-core power coupling coefficients are compared and discussed. (authors)

To date active research on laser-driven plasma-based accelerators have achieved great progress on production of high-energy, high-quality electron and photon beams in a compact scale. Such laser plasma accelerators have been envisaged bringing a wide range of applications in basic, medical and industrial sciences. Here inheriting the groundbreaker’s review article on “Laser Acceleration and its future” [Toshiki Tajima, (2010)],1) we would like to review recent progress of producing such electron beams due to relativistic laser-plasma interactions followed by laser wakefield acceleration and lead to the scaling formulas that are useful to design laser plasma accelerators with controllability of beam energy and charge. Lastly specific examples of such laser-driven electron/photon beam sources are illustrated. PMID:26062737

Understanding consumer decisions using behavioral economics.

Science.gov (United States)

Zandstra, Elizabeth H; Miyapuram, Krishna P; Tobler, Philippe N

2013-01-01

Consumers make many decisions in everyday life involving finances, food, and health. It is known from behavioral economics research that people are often driven by short-term gratification, that is, people tend to choose the immediate, albeit smaller reward. But choosing the delayed reward, that is, delaying the gratification, can actually be beneficial. How can we motivate consumers to resist the "now" and invest in their future, leading to sustainable or healthy habits? We review recent developments from behavioral and neuroimaging studies that are relevant for understanding consumer decisions. Further, we present results from our field research that examined whether we can increase the perceived value of a (delayed) environmental benefit using tailored communication, that is, change the way it is framed. More specifically, we investigated whether we can boost the value of an abstract, long-term "green" claim of a product by expressing it as a concrete, short-term benefit. This is a new application area for behavioral economics. Copyright © 2013 Elsevier B.V. All rights reserved.

Frugal Droplet Microfluidics Using Consumer Opto-Electronics.

Frot, Caroline; Taccoen, Nicolas; Baroud, Charles N

2016-01-01

The maker movement has shown how off-the-shelf devices can be combined to perform operations that, until recently, required expensive specialized equipment. Applying this philosophy to microfluidic devices can play a fundamental role in disseminating these technologies outside specialist labs and into industrial use. Here we show how nanoliter droplets can be manipulated using a commercial DVD writer, interfaced with an Arduino electronic controller. We couple the optical setup with a droplet generation and manipulation device based on the "confinement gradients" approach. This device uses regions of different depths to generate and transport the droplets, which further simplifies the operation and reduces the need for precise flow control. The use of robust consumer electronics, combined with open source hardware, leads to a great reduction in the price of the device, as well as its footprint, without reducing its performance compared with the laboratory setup.

Laser probe diagnostics: shadowgraphy, interferometry, and polarimetry were used for a comprehensive characterization of ionization wave dynamics inside a glass target induced by a laser-driven, relativistic electron beam. Experiments were done using the 50-TW Leopard laser at the University of Nevada, Reno. We show that for a laser flux of ∼2 × 10(18) W/cm2 a hemispherical ionization wave propagates at c/3 for 10 ps and has a smooth electron-density distribution. The maximum free-electron density inside the glass target is ∼2 × 10(19) cm-3, which corresponds to an ionization level of ∼0.1%. Magnetic fields and electric fields do not exceed ∼15 kG and ∼1 MV/cm, respectively. The electron temperature has a hot, ringlike structure with a maximum of ∼0.7 eV. The topology of the interference phase shift shows the signature of the "fountain effect", a narrow electron beam that fans out from the propagation axis and heads back to the target surface. Two-dimensional particle-in-cell (PIC) computer simulations demonstrate radial spreading of fast electrons by self-consistent electrostatic fields driven by laser. The very low ionization observed after the laser heating pulse suggests a fast recombination on the sub-ps time scale.

We hereby present results on ion acceleration mechanisms in non equilibrium plasmas generated by microwaves or high intensity laser pulses. Experiments point out that in magnetized plasmas X–B conversion takes place for under resonance values of the magnetic field, i.e. an electromagnetic mode is converted into an electrostatic wave. The strong self-generated electric field, of the order of 10{sup 7} V/m, causes a E × B drift which accelerates both ions and electrons, as it is evident by localized sputtering in the plasma chamber. These fields are similar (in magnitude) to the ones obtainable in laser generated plasmas at intensity of 10{sup 12} W/cm{sup 2}. In this latter case, we observe that the acceleration mechanism is driven by electrons drifting much faster than plasma bulk, thus generating an extremely strong electric field ∼10{sup 7} V/m. The two experiments confirm that ions acceleration at low energy is possible with table-top devices and following complementary techniques: i.e. by using microwave-driven (producing CW beams) plasmas, or non-equilibrium laser-driven plasmas (producing pulsed beams). Possible applications involve ion implantation, materials surface modifications, ion beam assisted lithography, etc.

Highlights: • Consumption/disposal habits of waste electrical and electronic toys. • Environmental education as a key factor to improve WEEE management. • Three environmental education actions to increase the collection of waste toys. - Abstract: This paper reports on a project focused on obtaining the current consumption and disposal habits of electrical and electronic toys from a survey aimed at parents of children of nine pre- and primary schools. In addition, it is also focused on identifying the most effective way of transmitting environmental information to parents and children to promote the collection of electrical and electronic toys at their end-of-life. The study was implemented in a Spanish municipality. With regard to the consumption habits, aspects related to the amount of toys that children receive annually and percentage of those which are electrical and electronic toys have been obtained and classified according to the family size. Results from Chi-squared analysis and Ordinal Logistic Regression show that there is a statistically significance relationship among these variables. Regarding disposal habits, aspects related to the reasons and way for discarding electrical and electronic toys, time that toys are kept at home or the willingness to rent or buy second hand e-toys have been obtained. What really attracts attention is that, apart from consumers who donate the toy to family or social associations, 67.1% of consumers discard them along with other waste fractions in domestic bins, whereas only 32.9% do so at recycling points, as Directive 2012/19/EU requires. To increase this percentage, three environmental education actions (distinguishing from each other by the way used to transmit the environmental information: paper, audiovisual or personal communication) have been designed, applied and evaluated their efficiency according to the amount of waste toys collected.

Why Consumers Misattribute Sponsorships to Non-Sponsor Brands: Differential Roles of Item and Relational Communications.

Science.gov (United States)

Weeks, Clinton S; Humphreys, Michael S; Cornwell, T Bettina

2018-02-01

Brands engaged in sponsorship of events commonly have objectives that depend on consumer memory for the sponsor-event relationship (e.g., sponsorship awareness). Consumers however, often misattribute sponsorships to nonsponsor competitor brands, indicating erroneous memory for these relationships. The current research uses an item and relational memory framework to reveal sponsor brands may inadvertently foster this misattribution when they communicate relational linkages to events. Effects can be explained via differential roles of communicating item information (information that supports processing item distinctiveness) versus relational information (information that supports processing relationships among items) in contributing to memory outcomes. Experiment 1 uses event-cued brand recall to show that correct memory retrieval is best supported by communicating relational information when sponsorship relationships are not obvious (low congruence). In contrast, correct retrieval is best supported by communicating item information when relationships are obvious (high congruence). Experiment 2 uses brand-cued event recall to show that, against conventional marketing recommendations, relational information increases misattribution, whereas item information guards against misattribution. Results suggest sponsor brands must distinguish between item and relational communications to enhance correct retrieval and limit misattribution. Methodologically, the work shows that choice of cueing direction is critical in differentially revealing patterns of correct and incorrect retrieval with pair relationships.

Gain physics of rf-linac-driven xuv free-electron lasers

International Nuclear Information System (INIS)

Goldstein, J.C.; McVey, B.D.; Newnam, B.E.

1986-01-01

In an rf-linac-driven xuv free-electron laser oscillator, the gain depends on the details of the shape of the electron beam's phase-space distribution, particularly the distribution of electrons in the transverse (to the direction of propagation) position and velocity coordinates. This strong dependence occurs because the gain in this device is inhomogeneously broadened. Our previous theoretical studies have assumed that the transverse phase space distribution is a product of uncorrelated Gaussian functions. In the present work, we shall present the results of a theoretical study of the gain for non-Gaussian phase-space distributions. Such distributions arise either from a better representation of the electron beam from an rf-linac or from an emittance filter applied to the beam after the linac

Full Text Available The growth of the Internet heavily influences people’s lives every day, especially by the development of Social Networking Sites (SNS, which since their first appearance have been constantly recording a growing number of users. The main purpose of this paper is to identify the significance of SNS in relation to two activities of individual users: communication and consumer behaviour. The study focuses on the three most popular SNS in three neighbouring countries (Germany, Poland, and Russia namely, FACEBOOK, VKONTAKTE, and YOUTUBE. The methodological approach is twofold: firstly, the authors developed a theoretical background of the areas of using SNS and formulated research questions; secondly, they applied the PAPI and CAWI methods for the data analysis. Regarding the researched activities, it should be noted that SNS users use these platforms more often for communication than consumer actions. The most useful here is FACEBOOK in comparison to YOUTUBE. This study provides results, which can be useful in the management of the enterprises that use SNS for their marketing communication in Germany, Poland, and Russia.

Microwave-driven experiments and particle simulation calculations are presented that model s-polarized laser light incident on a pellet. In the microwave experiments, the incident microwaves are observed to decay into ion and electron waves near the critical density if the microwave power is above a well-defined threshold. Significant absorption, thermal electron heating, and hot electron generation are observed for microwave powers above a few times threshold. Strong absorption, strong profile modification, strongly heated hot electrons with a Maxwellian distribution, a hot-electron temperature that increases slowly with power, and a hot-electron density that is almost constant, are all observed in both the microwave experiments and simulation calculations for high powers. In addition, the thermal electrons are strongly heated for high powers in the microwave experiments

Li, Y.; Xia, G.; Lotov, K. V.; Sosedkin, A. P.; Hanahoe, K.; Mete-Apsimon, O.

2017-10-01

Simulations of proton-driven plasma wakefield accelerators have demonstrated substantially higher accelerating gradients compared to conventional accelerators and the viability of accelerating electrons to the energy frontier in a single plasma stage. However, due to the strong intrinsic transverse fields varying both radially and in time, the witness beam quality is still far from suitable for practical application in future colliders. Here we demonstrate the efficient acceleration of electrons in proton-driven wakefields in a hollow plasma channel. In this regime, the witness bunch is positioned in the region with a strong accelerating field, free from plasma electrons and ions. We show that the electron beam carrying the charge of about 10% of 1 TeV proton driver charge can be accelerated to 0.6 TeV with a preserved normalized emittance in a single channel of 700 m. This high-quality and high-charge beam may pave the way for the development of future plasma-based energy frontier colliders.

Electronic journals and scholarly communication: a citation and reference study

Directory of Open Access Journals (Sweden)

Stephen P. Harter

1996-01-01

Full Text Available The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (e-journals on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

Using a combination of computational simulations, atomic-scale resolution imaging and phenomenological modelling, we examine the underlying mechanism for nanodomain restructuring in lead zirconate titanate nanodisks driven by electron beams. The observed subhertz nanodomain dynamics are identified with relaxation oscillations where the charging/discharging cycle time is determined by saturation of charge traps and nanodomain wall creep. These results are unusual in that they indicate very slow athermal dynamics in nanoscale systems, and possible applications of gated versions are discussed.

Radiation-Hardened Electronics for Advanced Communications Systems

Whitaker, Sterling

2015-01-01

Novel approach enables high-speed special-purpose processors Advanced reconfigurable and reprogrammable communication systems will require sub-130-nanometer electronics. Legacy single event upset (SEU) radiation-tolerant circuits are ineffective at speeds greater than 125 megahertz. In Phase I of this project, ICs, LLC, demonstrated new base-level logic circuits that provide SEU immunity for sub-130-nanometer high-speed circuits. In Phase II, the company developed an innovative self-restoring logic (SRL) circuit and a system approach that provides high-speed, SEU-tolerant solutions that are effective for sub-130-nanometer electronics scalable to at least 22-nanometer processes. The SRL system can be used in the design of NASA's next-generation special-purpose processors, especially reconfigurable communication processors.

2003-01-01

Electron temperature gradient (ETG) driven instability in toroidal plasmas is studied with gyrokinetic theory. The full electron kinetics is considered. The upgraded numerical scheme for solving the integral eigenvalue equations allows the study of both growing and damping modes, and thus direct calculation of critical gradient. Algebraic formulas for the critical gradient with respect to ratio of electron temperature over ion temperature and to toroidicity are given. An estimation for turbulence induced transport is presented. (author)

Scharlach, Andrew; Graham, Carrie; Lehning, Amanda

2012-06-01

This study examines the characteristics of the "Village" model, an innovative consumer-driven approach that aims to promote aging in place through a combination of member supports, service referrals, and consumer engagement. Thirty of 42 fully operational Villages completed 2 surveys. One survey examined Villages' member characteristics, membership types, and fee structures. An additional survey collected information about organizational mission, goals, methods of operation, funding sources, challenges, and older adults' roles. Villages provide a variety of support services designed to help members age in place, meet service needs, and promote health and quality of life. Most Villages operate relatively autonomously, relying primarily on member fees and donations. Village members typically are highly involved in organizational development and oversight and provide services to other members in almost half of the Villages. Members predominantly are aged 65 years or older, White, non-Hispanic, homeowners, and have care needs that are slightly lower than those of the elderly U.S. population overall. Villages are a promising model for addressing service needs among middle-class seniors who seek to age in their own homes and communities. Financial sustainability is apt to be a challenge unless Villages secure more stable sources of funding. Organizational sustainability may be promoted through affiliations with social service agencies and other sources of technical and financial assistance. Future evaluation is needed regarding the impact of Villages on elders' ability to age in place as well as the long-term sustainability of the Village model.

Consumer protection act for digital products

Science.gov (United States)

Hampel, Viktor E.

1996-03-01

This report proposes a `Consumer Protection Act for Digital Products' to support electronic commerce and to control the increasing abuse and lack of security on the national information highways. Patterned after the `Food and Drug Act of 1906 (21 USC)' and subsequent legislation, a new agency similar to that of the FDA would have the authority `to develop administrative policy with regard to the safety, effectiveness, and labeling of digital products and their communications for human use, and to review and evaluate new applications of such products.' Specifically, it is proposed that standards, originally developed by the defense industry for the labeling, enveloping, and authentication of digital products delivered to the Government, be extended to promote global electronic commerce by protecting the intellectual property rights of producers, establishing their liability for the end-use of digital products, and give consumers means for informed decision making and purchase.

Production of hydrogen and deuterium negative ions in an electron cyclotron resonance driven plasma

Energy Technology Data Exchange (ETDEWEB)

Dougar-Jabon, V.D. [Industrial Univ. of Santander, Bucaramanga (Colombia)

2001-04-01

An electron cyclotron resonance source with driven plasma rings for hydrogen isotope ion production is studied. Extracted currents of positive and negative ions depending on gas pressure, microwave power value and extraction voltage are obtained. The study shows that the negative ion yield is an order of magnitude higher than the yield of positive particles when a driven ring is in contact with the surface of the plasma electrode. The production of negative ions of deuterium, D{sup -}, is close to the production of negative ions of light hydrogen isotope, H{sup -}. The comparison of the experimental data with the calculated ones shows that the most probable process of the H{sup -} and D{sup -} ion formation in the electron cyclotron driven plasma is dissociative attachment of electrons to molecules in high Rydberg states. For hydrogen ions and ions of deuterium, the negative current at a microwave power of 200 W through a 3-mm aperture and 8 kV extraction voltage are 4.7 mA and 3.1 mA respectively. (orig.)

Arney, Jennifer; Street, Richard L; Naik, Aanand D

2013-01-01

Direct-to-consumer advertising (DTCA) is ubiquitous in media outlets, but little is known about the ways in which consumers' values, needs, beliefs, and biases influence the perceived meaning and value of DTCA. This article aims to identify the taxonomy of readership categories that reflect the complexity of how health care consumers interact with DTCA, with particular focus on individuals' perceptions of print DTCA in popular magazines. Respondent-driven sampling was used to recruit 18 male and female magazine readers and 18 male and female prescription medication users aged 18-71 years. Semi-structured, in-depth interviews with consumers about their attentiveness, motivations, perceived value, and behavioral responses to DTCA were conducted. The analyses were guided by principles of grounded theory analysis; four categories that vary in consumers' attentiveness, motivations, perceived value, and behavioral responses to DTCA were identified. Two categories - the lay physician and the informed shopper - see value in information from DTCA and are likely to seek medical care based on the information. One category - the voyeur - reads DTCA, but is not likely to approach a clinician regarding advertised information. The fourth category - the evader - ignores DTCA and is not likely to approach a clinician with DTCA information. Responses to DTCA vary considerably among consumers, and physicians should view patients' understanding and response to DTCA within the context of their health-related needs. Patients' comments related to DTCA may be used as an opportunity to engage and understand patients' perspectives about illness and medication use. Clinicians may use information about these categories to facilitate shared understanding and improve communication within the doctor-patient relationship.

Consumers' health-related perceptions of bread - Implications for labeling and health communication.

2018-02-01

There is a wide variety of commercial bread types and the present study identifies potential pitfalls in consumer evaluations of bread from a health perspective. The aim is to describe consumers' health-related perceptions of bread by exploring which health-related quality attributes consumers associate with bread and whether there are differences with regard to age, gender and education level. A postal and web-based sequential mixed-mode survey (n = 1134, 62% responded online and 38% by paper) with open-ended questions and an elicitation task with pictures of commercial breads were used. Responses were content analyzed and inductively categorized. Three fourths (n = 844) knew of breads they considered healthy; these were most commonly described using terms such as "coarse," "whole grain," "fiber rich," "sourdough," "crisp," "less sugar," "dark," "rye," "seeds," "a commercial brand," "homemade" and "kernels." The breads were perceived as healthy mainly because they "contain fiber," are "good for the stomach," have good "satiation" and beneficial "glycemic properties." The frequency of several elicited attributes and health effects differed as a function of age group (18-44 vs. 45-80 years), gender and education level group (up to secondary education vs. university). Difficulties identifying healthy bread were perceived as a barrier for consumption especially among consumers with a lower education level. Several of the health effects important to consumers cannot be communicated on food packages and consumers must therefore use their own cues to identify these properties. This may lead to consumers being misled especially if a bread is labeled e.g., as a sourdough bread or a rye bread, despite a low content. Copyright © 2017 Elsevier Ltd. All rights reserved.

Maolikul, S.; Kiatgamolchai, S.; Chavarnakul, T.

2012-06-01

In the context of information and communication technology (ICT) trend for worldwide individuals, social life becomes digital and portable consumer electronic devices (PCED) powered by conventional power supply from batteries have been evolving through miniaturization and various function integration. Thermoelectric generators (TEG) were hypothesized for its potential role of battery charger to serve the shining PCED market. Hence, this paper, mainly focusing at the metropolitan market in Thailand, aimed to conduct architectural innovation foresight and to develop scenarios on potential exploitation approach of PCED battery power supply with TEG charger converting power from ambient heat source adjacent to individual's daily life. After technical review and assessment for TEG potential and battery aspect, the business research was conducted to analyze PCED consumer behavior for their PCED utilization pattern, power supply lack problems, and encountering heat sources/sinks in 3 modes: daily life, work, and leisure hobbies. Based on the secondary data analysis from literature and National Statistical Office of Thailand, quantitative analysis was applied using the cluster probability sampling methodology, statistically, with the sample size of 400 at 0.05 level of significance. In addition, the qualitative analysis was conducted to emphasize the rationale of consumer's behavior using in-depth qualitative interview. Scenario planning technique was also used to generate technological and market trend foresight. Innovation field and potential scenario for matching technology with market was proposed in this paper. The ingredient for successful commercialization of battery power supply with TEG charger for PCED market consists of 5 factors as follows: (1) PCED characteristic, (2) potential ambient heat sources/sinks, (3) battery module, (4) power management module, and the final jigsaw (5) characteristic and adequate arrangement of TEG modules.

The effects of finite parallel temperature are investigated for a hot electron plasma with sufficiently large beta that the magnetic field scale length (Δ/sub B/) is small compared with the vacuum field radius of curvature (R). Numerical and analytical estimates of stability boundaries are obtained for the four possible modes that can be treated in this limit: the conventional hot electron interchange, the high frequency hot electron interchange (ω > ω/sub ci/), the compressional Alfven mode, and the interacting pressure-driven interchange

That the usability of electronic consumer products is under pressure is attributed to an incre...

Price-transparency and cost accounting: challenges for health care organizations in the consumer-driven era.

Science.gov (United States)

Hilsenrath, Peter; Eakin, Cynthia; Fischer, Katrina

2015-01-01

Health care reform is directed toward improving access and quality while containing costs. An essential part of this is improvement of pricing models to more accurately reflect the costs of providing care. Transparent prices that reflect costs are necessary to signal information to consumers and producers. This information is central in a consumer-driven marketplace. The rapid increase in high deductible insurance and other forms of cost sharing incentivizes the search for price information. The organizational ability to measure costs across a cycle of care is an integral component of creating value, and will play a greater role as reimbursements transition to episode-based care, value-based purchasing, and accountable care organization models. This article discusses use of activity-based costing (ABC) to better measure the cost of health care. It describes examples of ABC in health care organizations and discusses impediments to adoption in the United States including cultural and institutional barriers. © The Author(s) 2015.

Applying social marketing in health care: communicating evidence to change consumer behavior.

Science.gov (United States)

Evans, W Douglas; McCormack, Lauren

2008-01-01

Social marketing uses commercial marketing strategies to change individual and organizational behavior and policies. It has been effective on a population level across a wide range of public health and health care domains. There is limited evidence of the effectiveness of social marketing in changing health care consumer behavior through its impact on patient-provider interaction or provider behavior. Social marketers need to identify translatable strategies (e.g., competition analysis, branding, and tailored messages) that can be applied to health care provider and consumer behavior. Three case studies from social marketing illustrate potential strategies to change provider and consumer behavior. Countermarketing is a rapidly growing social marketing strategy that has been effective in tobacco control and may be effective in countering pharmaceutical marketing using specific message strategies. Informed decision making is a useful strategy when there is medical uncertainty, such as in prostate cancer screening and treatment. Pharmaceutical industry marketing practices offer valuable lessons for developing competing messages to reach providers and consumers. Social marketing is an effective population-based behavior change strategy that can be applied in individual clinical settings and as a complement to reinforce messages communicated on a population level. There is a need for more research on message strategies that work in health care and population-level effectiveness studies.

Electronic health record tools' support of nurses' clinical judgment and team communication.

Kossman, Susan P; Bonney, Leigh Ann; Kim, Myoung Jin

2013-11-01

Nurses need to quickly process information to form clinical judgments, communicate with the healthcare team, and guide optimal patient care. Electronic health records not only offer potential for enhanced care but also introduce unintended consequences through changes in workflow, clinical judgment, and communication. We investigated nurses' use of improvised (self-made) and electronic health record-generated cognitive artifacts on clinical judgment and team communication. Tanner's Clinical Judgment Model provided a framework and basis for questions in an online survey and focus group interviews. Findings indicated that (1) nurses rated self-made work lists and medication administration records highest for both clinical judgment and communication, (2) tools aided different dimensions of clinical judgment, and (3) interdisciplinary tools enhance team communication. Implications are that electronic health record tool redesign could better support nursing work.

Free-electron laser driven by the LBNL laser-plasma accelerator

A design of a compact free-electron laser (FEL), generating ultra-fast, high-peak flux, XUV pulses is presented. The FEL is driven by ahigh-current, 0.5 GeV electron beam from the Lawrence Berkeley National Laboratory (LBNL) laser-plasma accelerator, whose active acceleration length is only a few centimeters. The proposed ultra-fast source (∼10 fs) would be intrinsically temporally synchronized to the drive laser pulse, enabling pump-probe studies in ultra-fast science. Owing to the high current (>10 kA) of the laser-plasma-accelerated electron beams, saturated output fluxes are potentially greater than 10 13 photons/pulse. Devices based both on self-amplified spontaneous emission and high-harmonic generated input seeds, to reduce undulator length and fluctuations, are considered.

2009-04-27

A hybrid electronic/optical system for synchronizing a chaotic receiver to a chaotic transmitter has been demonstrated. The chaotic signal is generated electronically and injected, in addition to a constant bias current, to a semiconductor laser to produce an optical carrier for transmission. The optical chaotic carrier is photodetected to regenerate an electronic signal for synchronization in a matched electronic receiver The system has been successfully used for the transmission and recovery of a chaos masked message that is added to the chaotic optical carrier. Past demonstrations of synchronized chaos based, secure communication systems have used either an electronic chaotic carrier or an optical chaotic carrier (such as the chaotic output of various nonlinear laser systems). This is the first electronic/optical hybrid system to be demonstrated. We call this generation of a chaotic optical carrier by electronic injection.

Electric field driven plasmon dispersion in AlGaN/GaN high electron mobility transistors

2013-01-01

We present a theoretical study on the electric field driven plasmon dispersion of the two-dimensional electron gas (2DEG) in AlGaN/GaN high electron mobility transistors (HEMTs). By introducing a drifted Fermi—Dirac distribution, we calculate the transport properties of the 2DEG in the AlGaN/GaN interface by employing the balance-equation approach based on the Boltzmann equation. Then, the nonequilibrium Fermi—Dirac function is obtained by applying the calculated electron drift velocity and electron temperature. Under random phase approximation (RPA), the electric field driven plasmon dispersion is investigated. The calculated results indicate that the plasmon frequency is dominated by both the electric field E and the angle between wavevector q and electric field E. Importantly, the plasmon frequency could be tuned by the applied source—drain bias voltage besides the gate voltage (change of the electron density)

Consumer-to-Consumer Electronic Commerce: A Distinct Research Stream

2014-01-01

A Time-Dependent Configuration Interaction approach using multiple Feshbach partitionings, corresponding to multiple ionization stages of a laser-driven molecule, has recently been proposed [T.-T. Nguyen-Dang and J. Viau-Trudel, J. Chem. Phys. 139, 244102 (2013)]. To complete this development toward a fully ab-initio method for the calculation of time-dependent electronic wavefunctions of an N-electron molecule, we describe how tools of multiconfiguration quantum chemistry such as the management of the configuration expansion space using Graphical Unitary Group Approach concepts can be profitably adapted to the new context, that of time-resolved electronic dynamics, as opposed to stationary electronic structure. The method is applied to calculate the detailed, sub-cycle electronic dynamics of BeH 2 , treated in a 3–21G bound-orbital basis augmented by a set of orthogonalized plane-waves representing continuum-type orbitals, including its ionization under an intense λ = 800 nm or λ = 80 nm continuous-wave laser field. The dynamics is strongly non-linear at the field-intensity considered (I ≃ 10 15 W/cm 2 ), featuring important ionization of an inner-shell electron and strong post-ionization bound-electron dynamics

THE COPRODUCTION BETWEEN PRODUCER AND CONSUMER AS PART OF THE EXPERIENCE ECONOMY

Directory of Open Access Journals (Sweden)

BARABAȘ MARIA

2015-12-01

Full Text Available Traditional economic literature is based on the model that separate producer of consumer, considering that, while the producer creates the value, the consumer damage it during the use. There is, however, a new trend that I approach, too, in this work, which perceives consumer in another aspect, that of co-producer. The main purpose of the paper is to examine if, via co-production with the consumer, the companies register costs’ decreases and thereby increases in sales volume. For this, I compared the estimated expenditure of a specific agricultural firm moving to coproduction with the consumer, on the one hand, and data that reflects the results of the company if it does not engages in co-production, on the other hand . I also brought up the case of Swedish company Ikea , which represents a proof that the consumers’ interest grows if he participate in certain stages of production. Based on these data , I surprised the idea that by the effect of prices’ decrease, the co-production between producer and consumer leads to increasing the sales volume of the company and also its performance. The co-production between producer and consumer is a phrase which seeks yet for an identity. The growth and diversity of consumtion is closely linked of certain favorable conditions, such as the development of the New Economy and the unprecedented gain in the informational means of communication. Developed in the 90’s, the World Wide Web technology , the e-mail and the social networks have led to significant exchanges of information, impressions and feedback from consumers. At the same time they have created, for producers, the opportunity to make themselves known in a quick and economical way, to make known their products, to sell goods or services, no matter where in the world. In less than a minute, one can see the goods offered by a company and as fast, can purchase an item or make a financial transaction. Electronic commerce is based on processing and

Asthma is a common childhood chronic lung disease affecting greater than 10% of children in the United States. School nurses are in a unique position to close gaps in care. Indeed, effective asthma management is more likely to result when providers, family, and schools work together to optimize the patient's treatment plan. Currently, effective communication between schools and healthcare systems through electronic medical record (EMR) systems remains a challenge. The goal of this feasibility pilot was to link the school-based care team with primary care providers in the healthcare system network via electronic communication through the EMR, on behalf of pediatric asthma patients who had been hospitalized for an asthma exacerbation. The implementation process and the potential impact of the communication with providers on the reoccurrence of asthma exacerbations with the linked patients were evaluated. By engaging stakeholders from the school system and the healthcare system, we were able to collaboratively design a communication process and implement a pilot which demonstrated the feasibility of electronic communication between school nurses and primary care providers. Outcomes data was collected from the electronic medical record to examine the frequency of asthma exacerbations among patients with a message from their school nurse. The percent of exacerbations in the 12 months before and after electronic communication was compared using McNemar's test. The pilot system successfully established communication between the school nurse and primary care provider for 33 students who had been hospitalized for asthma and a decrease in hospital admissions was observed with students whose school nurse communicated through the EMR with the primary care provider. Findings suggest a collaborative model of care that is enhanced through electronic communication via the EMR could positively impact the health of children with asthma or other chronic illnesses.

Combining a highly sensitive sensor platform with highly selective recognition elements is essential for micro/nanotechnology-based electronic nose applications. Particularly, the regeneration sensor surface and its conditions are key issues for practical e-nose applications. We propose a highly sensitive piezoelectric-driven microcantilever array chip with highly selective peptide receptors. By utilizing the peptide receptor, which was discovered by a phase display screening process, we immobilized a dinitrotoluene (DNT) specific peptide as well as a DNT nonspecific peptide on the surface of the cantilever array. The delivery of DNT gas via pressure-driven flow led to a greater instant response of ∼30 Hz, compared to diffusion only (∼15 Hz for 15 h). Using a simple pressure-driven air flow of ∼50 sccm, we confirmed that a ratio of ∼70% of the specific-bounded sites from DNT gas molecules could be regenerated, showing re-usability of the peptide receptor in on-site monitoring for electronic nose applications.

Contemporary state-of-the-art healthcare facilities are incorporating technology into their building design to improve communication and patient care. However, technological innovations may also have unintended consequences. This study seeks to better understand how technology influences interprofessional communication within a hospital setting based in the United States. Nine focus groups were conducted including a range of healthcare professions. The focus groups explored practitioners' experiences working on two floors of a newly designed hospital and included questions about the ways in which technology shaped communication with other healthcare professionals. All focus groups were recorded, transcribed, and coded to identify themes. Participant responses focused on the electronic medical record, and while some benefits of the electronic medical record were discussed, participants indicated use of the electronic medical record has resulted in a reduction of in-person communication. Different charting approaches resulted in barriers to communication between specialties and reduced confidence that other practitioners had received one's notes. Limitations in technology-including limited computer availability, documentation complexity, and sluggish sign-in processes-also were identified as barriers to effective and timely communication between practitioners. Given the ways in which technology shapes interprofessional communication, future research should explore how to create standardised electronic medical record use across professions at the optimal level to support communication and patient care.

This study addresses a void in the literature on direct-to-consumer prescription drug advertising (DTCA) with a theory-based content analysis. The findings indicate that Taylor's communication strategy wheel provides insight into what and how pharmaceutical marketers communicate with consumers by means of DTCA. Major findings are summarized as follows: (a) In most DTC ads, informational and transformational message themes and creative approaches were simultaneously used, indicating a combination strategy; (b) DTCA message themes were associated with creative strategies in alignment with Taylor's framework; and (c) message themes and creative strategies varied across therapeutic categories and DTCA categories with different levels of ad spending. Theoretical and practical implications of the findings are discussed.

Who speaks for the health consumer?

Although consumer-directed health care has become a fashionable concept in recent years, stories abound asking whether the so-called free market in health care can provide adequate access to quality health care at an affordable price. In spite of these concerns, consumer-directed health care continues as the face of legitimacy behind an industry-driven campaign to limit regulatory protections of the consumer in the market and encourage the growth of health insurance products that place spending options closer to the consumer, whether or not these options are available, affordable, or easily understood. Understanding whether this empowerment is real begins with first asking what it now means to be a health consumer. This commentary offers perspective on the dilemma faced by millions of Americans in navigating our health care system under the assumption that market-driven choices foster consumer empowerment in health care, and suggests approaches for expanding the true consumer voice.

A three-phase model proposal for the evolution of scientific communication: from first print periodicals to current electronic communication system

Directory of Open Access Journals (Sweden)

Patrícia Bertin

Full Text Available Scientific communication has undergone deep transformations, since the emergence of Internet. Aiming to provide further thought on the evolution of scientific communication, this paper features a historical overview of the scientific communication advances over the last twenty years through a three-phase model for the evolution of the electronic journal and the preprints services, and presents Brazilian contemporary panorama for scientific communication. The three-phase model presented in this work is an adaptation of that one proposed by Tenopir et al. (2003 to describe the patterns of journal use by scientists since 1990. The early evolutionary phase followed the emergence of the first digital journals and the creation of repositories in the Web for publishing preliminary versions of scientific literature on the author’s initiative; by that time, most academics reproved electronic publishing initiatives. From 1996 and forward, in the consolidation phase, electronic journals were commonly identical to their print counterparts; the acceptance of the electronic format began to increase, and preprint services got underway in several disciplines. The advanced evolutionary phase started with the world discussion on open access to scientific information. The comparison of the current electronic journal with that viewed by enthusiasts in the first years of the 1990s shows that some aspects still remain to be improved in electronic formal and informal communication, towards effective dissemination of scientific information.

Enhanced laser-energy coupling to dense plasmas driven by recirculating electron currents

The absorption of laser energy and dynamics of energetic electrons in dense plasma is fundamental to a range of intense laser-driven particle and radiation generation mechanisms. We measure the total reflected and scattered laser energy as a function of intensity, distinguishing between the influence of pulse energy and focal spot size on total energy absorption, in the interaction with thin foils. We confirm a previously published scaling of absorption with intensity by variation of laser pulse energy, but find a slower scaling when changing the focal spot size. 2D particle-in-cell simulations show that the measured differences arise due to energetic electrons recirculating within the target and undergoing multiple interactions with the laser pulse, which enhances absorption in the case of large focal spots. This effect is also shown to be dependent on the laser pulse duration, the target thickness and the electron beam divergence. The parameter space over which this absorption enhancement occurs is explored via an analytical model. The results impact our understanding of the fundamental physics of laser energy absorption in solids and thus the development of particle and radiation sources driven by intense laser–solid interactions.

We experimentally and numerically investigate the performance of an advanced ultrafast electron source, based on two-photon photoemission from a tungsten needle cathode incorporated in an electron microscope gun geometry. Emission properties are characterized as a function of the electrostatic gun settings, and operating conditions leading to laser-triggered electron beams of very low emittance (below 20 nm mrad) are identified. The results highlight the excellent suitability of optically driven nano-cathodes for the further development of ultrafast transmission electron microscopy

FeSe is structurally the simplest of Fe-based superconductors, and exhibits a tetragonal-to-orthorhombic structural transition at ~ 90 K, but no long-range magnetism at any temperature. We report measurements of the resistivity anisotropy in FeSe above Ts finding a large and divergent response to an applied strain, with a comparable magnitude and temperature-dependence to measurements in Ba(Fe1-xCox)2As2, but opposite sign. We compare this data with literature reports on NMR and our own ARPES data, which taken together indicate that the structural transition is electronically-driven with orbital degrees of freedom playing a central role. This work was supported by EPSRC, UK (EP/I004475/1) and Diamond Light Source.

Mobile communication with the medical-care team has the potential to decrease stress among parents of infants admitted to the neonatal intensive care unit (NICU). We assessed mobile use and communication preferences in a population of urban minority NICU mothers. A 30-question English language survey was administered to mothers of NICU patients. The survey was completed by 217 mothers, 75% were Black, and 75% reported annual household income below $20 000. Only 56% had a computer with Internet access at home, but 79% used smartphones. Most (79%) have searched the Internet for health information in the past year. Receiving electronic messages about their babies was viewed favorably, and text messaging was the preferred platform. The majority of mothers felt electronic messaging would improve communication but should not replace verbal communication. Mobile communication is used widely in this population of NICU mothers and could potentially improve provider-parent communication and reduce parental stress.

Bunch decompression for laser-plasma driven free-electron laser demonstration schemes

Directory of Open Access Journals (Sweden)

T. Seggebrock

2013-07-01

Full Text Available X-ray free-electron lasers (FELs require a very high electron beam quality in terms of emittance and energy spread. Since 2004 high quality electrons produced by laser-wakefield accelerators have been demonstrated, but the electron quality up to now did not allow the operation of a compact x-ray FEL using these electrons. Maier et al. [Phys. Rev. X 2, 031019 (2012PRXHAE2160-330810.1103/PhysRevX.2.031019] suggested a concept for a proof-of-principle experiment allowing FEL operation in the vacuum ultraviolet range based on an optimized undulator and bunch decompression using electron bunches from a laser-plasma accelerator as currently available. In this paper we discuss in more detail how a chicane can be used as a bunch stretcher instead of a bunch compressor to allow the operation of a laser-wakefield accelerator driven FEL using currently available electrons. A scaling characterizing the impact of bunch decompression on the gain length is derived and the feasibility of the concept is tested numerically in a demanding scenario.

Hysteresis in consumer markets with focus on the mobile communications market

Science.gov (United States)

Twomey, C.

2008-11-01

Our aim here is to try to identify hysteresis in the switching patterns of consumers in the Irish mobile phone industry. It was not until the introduction by the Communication Regulator of full-number portability that consumers began to take advantage of the savings that switching mobile phone operator could produce. As with most relatively new industries, the awareness of savings is clouded by a lack of understanding of whats on offer and an underlying fear of change from something they have only just started to comprehend. With people changing company loyalties more frequently than ever at the prospect of better, more cost-efficient services, it is now the million euro question for the phone companies on how close they should match each others' offers to maximize their profits, and what their best pricing strategy should be to obtain an even larger share of the market. Through the use of experimental economics and by modelling switching behaviour using the Preisach model, along with observed and market data, we hope to both pose this problem and start the journey to answering this question.

2014-05-01

Full Text Available Electronic virtual markets can serve as an alternative tool for collecting information that is spread among numerous experts. This is the principal market functionality from the operators’ point of view. On the other hand it is profits that are the main interest of the market participants. What they expect from the market is liquidity as high as possible and the opportunity for unrestricted trading. Both the operator and the electronic market participant can be considered consumers of this particular market with reference to the requirements for the accuracy of its outputs but also for the market liquidity. Both the above mentioned groups of consumers (the operators and the participants themselves expect protection of their specific consumer rights, i.e. securing the two above mentioned functionalities of the market. These functionalities of the electronic market are, however, influenced by many factors, among others by participants’ activity. The article deals with the motivation tools that may improve the quality of the prediction market. In the prediction electronic virtual market there may be situations in which the commonly used tools for increasing business activities described in the published literature are not significantly effective. For such situations we suggest a new type of motivation incentive consisting in penalizing the individual market participants whose funds are not placed in the market. The functionality of the proposed motivation incentive is presented on the example of the existing data gained from the electronic virtual prediction market which is actively operated.

Mundane science use in a practice theoretical perspective: Different understandings of the relations between citizen-consumers and public communication initiatives build on scientific claims.

Science.gov (United States)

Halkier, Bente

2015-08-13

Public communication initiatives play a part in placing complicated scientific claims in citizen-consumers' everyday contexts. Lay reactions to scientific claims framed in public communication, and attempts to engage citizens, have been important subjects of discussion in the literatures of public understanding and public engagement with science. Many of the public communication initiatives, however, address lay people as consumers rather than citizens. This creates specific challenges for understanding public engagement with science and scientific citizenship. The article compares five different understandings of the relations between citizen-consumers and public issue communication involving science, where the first four types are widely represented in the Public Understanding of Science discussions. The fifth understanding is a practice theoretical perspective. The article suggests how the public understanding of and engagement in science literature can benefit from including a practice theoretical approach to research about mundane science use and public engagement. © The Author(s) 2015.

Healthcare has entered the electronic domain. This domain has improved data collection and storage abilities while allowing almost instantaneous access and results to data queries. Furthermore, it allows direct communication between healthcare providers and health consumers. The development of privacy, confidentiality, and security principles are necessary to protect consumers' interests against inappropriate access. Studies have shown that the health consumer is the important stakeholder in this process. With the international push toward electronic health records (EHRs), this article presents the importance of secure EHR systems from the public's perspective. To examine the public's perception of the security of electronic systems and report on how their perceptions can shape the building of stronger systems. A cross-sectional survey (September-November 2005) of people attending healthcare providers (n = 400) was conducted in the 4 major cities in New Zealand. Participants were surveyed on computer use, knowledge of EHR-proposed benefits and issues, security issues, and demographics. A total of 300 surveys were completed and returned (a 75% response rate), with 180 (60%) being women. One hundred eighty-eight (62.6%) had not heard of EHRs, with those who had heard of them indicating that they were a positive innovation in the health sector. However, 202 (73.3%) participants were highly concerned about the security and privacy of their health records. This feeling was further accentuated when participants were asked about security of electronic systems. Participants were worried about hackers (79.4%), vendor access (72.7%), and malicious software (68%). Participants were also introduced to various security systems, and in each case, over 80% of participants believed that these would make EHR systems more secure. A number of chi-square tests were carried out with each variable, and it was found that there were strong relationships between age, location, computer use

Adequate information and communication systems (ICT) can help to improve the communication in hospitals. Changes to the ICT-infrastructure of hospitals must be planed carefully. In order to support a comprehensive planning, we presented a classification of 81 common errors of the electronic communication on the MIE 2008 congress. Our objective now was to develop a data model that defines specific requirements for an adequate description of electronic communication processes We first applied the method of explicating qualitative content analysis on the error categorization in order to determine the essential process details. After this, we applied the method of subsuming qualitative content analysis on the results of the first step. A data model for the adequate description of electronic communication. This model comprises 61 entities and 91 relationships. The data model comprises and organizes all details that are necessary for the detection of the respective errors. It can be for either used to extend the capabilities of existing modeling methods or as a basis for the development of a new approach.

High Temperature Wireless Communication And Electronics For Harsh Environment Applications

In order for future aerospace propulsion systems to meet the increasing requirements for decreased maintenance, improved capability, and increased safety, the inclusion of intelligence into the propulsion system design and operation becomes necessary. These propulsion systems will have to incorporate technology that will monitor propulsion component conditions, analyze the incoming data, and modify operating parameters to optimize propulsion system operations. This implies the development of sensors, actuators, and electronics, with associated packaging, that will be able to operate under the harsh environments present in an engine. However, given the harsh environments inherent in propulsion systems, the development of engine-compatible electronics and sensors is not straightforward. The ability of a sensor system to operate in a given environment often depends as much on the technologies supporting the sensor element as the element itself. If the supporting technology cannot handle the application, then no matter how good the sensor is itself, the sensor system will fail. An example is high temperature environments where supporting technologies are often not capable of operation in engine conditions. Further, for every sensor going into an engine environment, i.e., for every new piece of hardware that improves the in-situ intelligence of the components, communication wires almost always must follow. The communication wires may be within or between parts, or from the engine to the controller. As more hardware is added, more wires, weight, complexity, and potential for unreliability is also introduced. Thus, wireless communication combined with in-situ processing of data would significantly improve the ability to include sensors into high temperature systems and thus lead toward more intelligent engine systems. NASA Glenn Research Center (GRC) is presently leading the development of electronics, communication systems, and sensors capable of prolonged stable

Methods A cross-sectional survey (September-November 2005) of people attending healthcare providers (n = 400) was conducted in the 4 major cities in New Zealand. Participants were surveyed on computer use, knowledge of EHR-proposed benefits and issues, security issues, and demographics. Results A total of 300 surveys were completed and returned (a 75% response rate), with 180 (60%) being women. One hundred eighty-eight (62.6%) had not heard of EHRs, with those who had heard of them indicating that they were a positive innovation in the health sector. However, 202 (73.3%) participants were highly concerned about the security and privacy of their health records. This feeling was further accentuated when participants were asked about security of electronic systems. Participants were worried about hackers (79.4%), vendor access (72.7%), and malicious software (68%). Participants were also introduced to various security systems, and in each case, over 80% of participants believed that these would make EHR systems more secure. A number of chi-square tests were carried out with each variable, and it was found that there were strong

Cocosila, Mihail; Archer, Norm

To develop a model of consumer perceptions of electronic personal health records (PHRs) and validate it in a comparative study between consumers who report having a chronic illness and those who report being well. A model of PHR use motivators and barriers was built and tested through a national survey across Canada. Data were collected from 800 individuals, 18 years or older. Half reported having a chronic illness or disability and half reported being well. Analyses were performed with structural equation modelling techniques. A total of 389 answers from chronically ill and 383 from well participants were collected. Perceived usefulness was the key explanation of the intention to use PHRs for both ill and well people (total effect of 0.601 and 0.565, respectively) followed by security, privacy and trust in PHRs (total effect of 0.377 and 0.479, respectively). Conversely, computer anxiety was perceived as a significant barrier (total effect of -0.327 for ill individuals and -0.212 for well individuals). The model proposed was appropriate in explaining key consumer positive and negative perceptions on electronic PHR use. We found little difference in perceptions of electronic PHRs between chronically ill and well individuals, although self-reporting their health status might have influenced the results. To increase the adoption rate of electronic PHRs among both chronically ill and well consumers it is necessary to reinforce consumer perceptions of the usefulness of and trust in these eHealth technologies while mitigating their anxieties about computer use in general.

Basic design considerations for free-electron lasers driven by electron beams from RF accelerators

Science.gov (United States)

Gover, A.; Freund, H.; Granatstein, V. L.; McAdoo, J. H.; Tang, C.-M.

A design procedure and design criteria are derived for free-electron lasers driven by electron beams from RF accelerators. The procedure and criteria permit an estimate of the oscillation-buildup time and the laser output power of various FEL schemes: with waveguide resonator or open resonator, with initial seed-radiation injection or with spontaneous-emission radiation source, with a linear wiggler or with a helical wiggler. Expressions are derived for computing the various FEL parameters, allowing for the design and optimization of the FEL operational characteristics under ideal conditions or with nonideal design parameters that may be limited by technological or practical constraints. The design procedure enables one to derive engineering curves and scaling laws for the FEL operating parameters. This can be done most conveniently with a computer program based on flowcharts given in the appendices.

Emittance Measurements from a Laser Driven Electron Injector

Energy Technology Data Exchange (ETDEWEB)

Reis, David A

2003-07-28

The Gun Test Facility (GTF) at the Stanford Linear Accelerator Center was constructed to develop an appropriate electron beam suitable for driving a short wavelength free electron laser (FEL) such as the proposed Linac Coherent Light Source (LCLS). For operation at a wavelength of 1.5 {angstrom}, the LCLS requires an electron injector that can produce an electron beam with approximately 1 {pi} mm-mrad normalized rms emittance with at least 1 nC of charge in a 10 ps or shorter bunch. The GTF consists of a photocathode rf gun, emittance-compensation solenoid, 3 m linear accelerator (linac), drive laser, and diagnostics to measure the beam. The rf gun is a symmetrized 1.6 cell, s-band high gradient, room temperature, photocathode structure. Simulations show that this gun when driven by a temporally and spatially shaped drive laser, appropriately focused with the solenoid, and further accelerated in linac can produce a beam that meets the LCLS requirements. This thesis describes the initial characterization of the laser and electron beam at the GTF. A convolved measurement of the relative timing between the laser and the rf phase in the gun shows that the jitter is less than 2.5 ps rms. Emittance measurements of the electron beam at 35 MeV are reported as a function of the (Gaussian) pulse length and transverse profile of the laser as well as the charge of the electron beam at constant phase and gradient in both the gun and linac. At 1 nC the emittance was found to be {approx} 13 {pi} mm-mrad for 5 ps and 8 ps long laser pulses. At 0.5 nC the measured emittance decreased approximately 20% in the 5 ps case and 40% in the 8 ps case. These measurements are between 40-80% higher than simulations for similar experimental conditions. In addition, the thermal emittance of the electron beam was measured to be 0.5 {pi} mm-mrad.

Full Text Available Currently, communication becomes more complex, faster and more dynamic every day. In this context, communication switches channels on traditional media to online applications. Thus, the electronic communication threatens, if not take the physical communication. We live in the era of information and the information they seek more ways than quick, cheap and accessible spread. Among the most common methods of electronic communication including website, electronic newsletter, blog and email custom. Online marketing has its roots in traditional marketing, but branch out and in a very obvious due to a unique features: interactivity. On the Internet, communication takes place in two directions and not just one, as in traditional marketing. At the same time, sellers and buyers can complete transactions from their homes or offices, at any time of day or night. Online marketing offers the advantage of presenting the interactive promotional materials that can meet the expectations of each type of buyer. Instead of creating a single message, as happens in the promotion of mass, marketing online allows the creation of "interactive brochure" that allow potential customers to choose the information that they want to see and when they want to see. Changing consumer behavior have had thoughts of marketing people who understand that the Internet is a very effective tool to attract, retain and loyalty the customer.

Evaluating communication to optimise consumer-directed energy efficiency interventions

International Nuclear Information System (INIS)

Wilson, Caroline

2014-01-01

Awareness campaigns, education and training programmes, label schemes and smart metering are all initiatives based on the principle that more and better information will encourage consumers to use less energy. Initiatives of this type can realise efficiency savings of up to 30%, and are likely to remain politically popular while preferred by the public to legislation or fines. While widespread, such programmes can have mixed performance, with savings often not reaching potential. This article investigates whether existing theoretical models can usefully be combined for evaluations of such message-oriented programmes. To do this it examines relationships between the variables of the Elaboration Likelihood Model (ELM) and Theory of Planned Behaviour (TPB) using empirical data from participants exposed to energy behaviour change projects. Analysis revealed that when used together, the theories may offer insight into the impact of messaging. While a single exploratory study can only describe what has occurred, it offers initial evidence to advocate further analysis of the potential of the combined framework. The author offers an illustration of how the framework might be utilised by other schemes by example of its application to a major EU project to save energy in Europe’s public buildings. - Highlights: • Consumer energy saving schemes have huge potential as a route to emissions reduction. • Mixed performance could be addressed by focus on impact of communication. • Evidence from exploratory study supports case for proposed evaluation framework. • Framework is illustrated at varying stages: planning, mid-term, and impact

Consumer health information technology can improve patient engagement in their health care and assist in navigating the complexities of health care delivery. However, the consumer health information technology offerings of health systems are often driven by provider rather than patient perspectives and inadequately address patient needs, thus limiting their adoption by patients. Consideration given to patients as stakeholders in the development of such technologies may improve adoption, efficacy, and consumer health information technology resource allocation. The aims of this paper were to measure patient interest in different health system consumer health information technology apps and determine the influence of patient characteristics on consumer health information technology interest. Patients seen at the Cleveland Clinic Neurological Institute were electronically surveyed on their interest in using different consumer health information technology apps. A self-efficacy scale, Patient Health Questionnaire-9 depression screen, and EuroQol 5 dimensions health-related quality of life scale were also completed by patients. Logistic regression was used to determine the influence of patient characteristics on interest in consumer health information technology in the categories of self-management, education, and communication. The majority of 3852 patient respondents had an interest in all technology categories assessed in the survey. The highest interest was in apps that allow patients to ask questions of providers (3476/3852, 90.24%) and to schedule appointments (3211/3839, 83.64%). Patient interest in consumer health information technology was significantly associated with greater depression symptoms, worse quality of life, greater health self-efficacy, and smartphone ownership (Pinformation technology development and their perspectives should consistently guide development efforts. Health systems should consider focusing on consumer health information technologies

Elucidating the electron transport in semiconductors via Monte Carlo simulations: an inquiry-driven learning path for engineering undergraduates

International Nuclear Information System (INIS)

Adorno, Dominique Persano; Pizzolato, Nicola; Fazio, Claudio

2015-01-01

Within the context of higher education for science or engineering undergraduates, we present an inquiry-driven learning path aimed at developing a more meaningful conceptual understanding of the electron dynamics in semiconductors in the presence of applied electric fields. The electron transport in a nondegenerate n-type indium phosphide bulk semiconductor is modelled using a multivalley Monte Carlo approach. The main characteristics of the electron dynamics are explored under different values of the driving electric field, lattice temperature and impurity density. Simulation results are presented by following a question-driven path of exploration, starting from the validation of the model and moving up to reasoned inquiries about the observed characteristics of electron dynamics. Our inquiry-driven learning path, based on numerical simulations, represents a viable example of how to integrate a traditional lecture-based teaching approach with effective learning strategies, providing science or engineering undergraduates with practical opportunities to enhance their comprehension of the physics governing the electron dynamics in semiconductors. Finally, we present a general discussion about the advantages and disadvantages of using an inquiry-based teaching approach within a learning environment based on semiconductor simulations. (paper)

Full Text Available The purpose of this study was to investigate the effects of young adult consumers' personal traits (high-tech involvement, experiment proclivity, and fashion/brand leadership on their perceptions of and attitudes toward using mobile devices for communications and commerce. The integrated stimulus-organism-responses paradigm (Fiore & Kim, 2007 served as the overarching framework, combining the uses and gratifications theory (Blumler & Katz, 1974 and the extended technology acceptance model (Kim, Ma, & Park, 2009. A convenience sample of 504 college students in 2 U. S. universities provided usable responses to our survey. Causal modeling analysis results showed that personal trait variables had significant impacts on the perceived ease of use, usefulness, and enjoyment, and attitudes toward mobile communication and mobile commerce. Findings also suggested that three perception variables positively influenced attitudes toward using mobile devices for communication as well as for commerce. This study provides empirical evidence of the potential of mobile commerce among young adult consumers.

Long-Range Intramolecular Electronic Communication in a Trinuclear Ruthenium Tropolonate Complex.

Yoshida, Jun; Kuwahara, Kyohei; Suzuki, Kota; Yuge, Hidetaka

2017-02-20

Dinuclear and trinuclear ruthenium complexes, [Ru(trop) 2 (C 2 trop)Ru(dppe)Cp] [2b; trop = tropolonato, C 2 trop = ethynyltropolonato, dppe = 1,2-bis(diphenylphosphino)ethane] and [Ru(trop){(C 2 trop)Ru(dppe)Cp} 2 ] (3), were synthesized, and their electronic and electrochemical properties were investigated in comparison with our previously reported complex [Ru(acac) 2 (C 2 trop)Ru(dppe)Cp] (2a). The electron-donating Ru II (dppe)Cp unit and electron-accepting Ru III O 6 unit are connected by C 2 trop in these complexes. 2a incorporates acetylacetonate as an ancillary ligand, while 2b and 3 incorporate tropolonate as an ancillary ligand. Every complex, 2a, 2b, and 3, exhibits similar UV-vis-near-IR (NIR) absorption spectra, demonstrating the lack of explicit intramolecular electronic communication between the units at least in the neutral state. The weak NIR absorption in 2a further diminished upon electrochemical oxidation, indicating almost no electronic communication between the units. In contrast, 2b and 3 exhibit broad NIR absorptions upon oxidation. Additionally, 3 exhibits four stepwise redox couples in the electrochemical study, which are formally attributed to [Ru II (trop) 3 ] - /[Ru III (trop) 3 ], two [Ru II (dppe)Cp]/[Ru III (dppe)Cp] + , and [Ru III (trop) 3 ]/[Ru IV (trop) 3 ] + couples. Clear separation of the redox couples attributed to the two terminal [Ru(dppe)Cp] units demonstrates the thermodynamic stability of the intermediate oxidation states with respect to disproportionation. Further electrochemical studies using an electrolyte including perfluorinated weakly coordinating anions and density functional theory/time-dependent density functional theory calculations confirmed the effect of ancillary ligands, acetylacetonate and tropolonate. In the case of 2a, electronic delocalization over the whole complex, especially over the [Ru(acac) 2 (trop)] unit, appears to be small. In contrast, the electronic communication between [Ru(dppe)Cp] and [Ru

Communication strategies to optimize commitments and investments in iron programming.

Science.gov (United States)

Griffiths, Marcia

2002-04-01

There is consensus that a communications component is crucial to the success of iron supplementation and fortification programs. However, in many instances, we have not applied what we know about successful advocacy and program communications to iron programs. Communication must play a larger and more central role in iron programs to overcome several common shortcomings and allow the use of new commitments and investments in iron programming to optimum advantage. One shortcoming is that iron program communication has been driven primarily by the supply side of the supply-demand continuum. That is, technical information has been given without thought for what people want to know or do. To overcome this, the communication component, which should be responsive to the consumer perspective, must be considered at program inception, not enlisted late in the program cycle as a remedy when interventions fail to reach their targets. Another shortcoming is the lack of program focus on behavior. Because the "technology" of iron, a supplement, or fortified or specific local food must be combined with appropriate consumer behavior, it is not enough to promote the technology. The appropriate use of technology must be ensured, and this requires precise and strategically crafted communications. A small number of projects from countries as diverse as Indonesia, Egypt, Nicaragua and Peru offer examples of successful communications efforts and strategies for adaptation by other countries.

Technology has enhanced modern health care delivery, particularly through accessibility to health information and ease of communication with tools like mobile device messaging (texting). However, text messaging has created new risks for breach of protected health information (PHI). In the current study, we sought to evaluate hand surgeons' knowledge and compliance with privacy and security standards for electronic communication by text message. A cross-sectional survey of the American Society for Surgery of the Hand membership was conducted in March and April 2016. Descriptive and inferential statistical analyses were performed of composite results as well as relevant subgroup analyses. A total of 409 responses were obtained (11% response rate). Although 63% of surgeons reported that they believe that text messaging does not meet Health Insurance Portability and Accountability Act of 1996 security standards, only 37% reported they do not use text messages to communicate PHI. Younger surgeons and respondents who believed that their texting was compliant were statistically significantly more like to report messaging of PHI (odds ratio, 1.59 and 1.22, respectively). A majority of hand surgeons in this study reported the use of text messaging to communicate PHI. Of note, neither the Health Insurance Portability and Accountability Act of 1996 statute nor US Department of Health and Human Services specifically prohibits this form of electronic communication. To be compliant, surgeons, practices, and institutions need to take reasonable security precautions to prevent breach of privacy with electronic communication. Communication of clinical information by text message is not prohibited under Health Insurance Portability and Accountability Act of 1996, but surgeons should use appropriate safeguards to prevent breach when using this form of communication.

2013-12-01

Full Text Available The article identifies needs of the target group, namely structure of motives, which justify making a decision to buy, in order to create efficient marketing strategy of an enterprise, which sell solar-driven equipment in Ukraine. There are five segments in the domestic market of helio-systems: individual consumers, recreation industry, agrarian industry, construction and social spheres. The article allocates 15 motives of acquisition of the solar-driven equipment for these segments, the most important of which are price, availability of solar energy, alternative price and energy saving. Besides, the structure of such motives is determined for each segment individually. In order to choose specific marketing instruments in the policy of promotion of solar-driven equipment, the article identifies differences in the form of goals of use and motives of acquisition between the specified consumer segments. The article reveals certain barriers that interfere with acquisition of solar-driven equipment – low level of trust into helio-systems, conservatism of consumers, absence of free applications for consumers – overcoming which is only possible with the help of certain marketing actions.

The number of multiple sclerosis (MS) information websites, online communities, and Web-based health education programs has been increasing. However, MS patients' willingness to use new ways of communication, such as websites, mobile phone application, short message service, or email with their physician, remains unknown. We designed a questionnaire to evaluate the a priori use of electronic communication methods by MS patients and to assess their acceptance of such tools for communication with their health care providers. We received complete data from 586 MS patients aged between 17 and 73 years. Respondents were surveyed in outpatient clinics across Germany using a novel paper-and-pencil questionnaire. In addition to demographics, the survey items queried frequency of use of, familiarity with, and comfort with using computers, websites, email, and mobile phones. About 90% of all MS patients used a personal computer (534/586) and the Internet (527/586) at least once a week, 87.0% (510/586) communicated by email, and 85.6% (488/570) communicated by mobile phone. When asked about their comfort with using electronic communication methods for communication with health care providers, 20.5% (120/586) accepted communication by mobile Internet application or short message service via mobile phone, 41.0% (240/586) by websites, 54.3% (318/586) by email service, and 67.8% (397/586) by at least one type of electronic communication. The level of a priori use was the best predictor for the acceptance of electronic communication with health care providers. Patients who reported already searching online for health information (odds ratio 2.4, P higher acceptance for Web-based communication. Patients who already scheduled appointments with their mobile phones (odds ratio 2.1, P = .002) were more likely to accept the use of mobile phone applications or short message service for communicating with their physician. The majority of MS patients seen at specialist centers already use

In this work, we numerically study the dynamics of vertical cavity surface emitting laser (VCSEL) firstly when it is driven by Chua's oscillator, secondly in case where it is driven by a broad frequency spectral bandwidth chaotic oscillator developed by Nana et al. [Commun. Nonlinear Sci. Numer. Simul. 14, 2266 (2009)]. We demonstrated that the VCSEL generated robust chaotic dynamics compared to the ones found in VCSEL subject to a sinusoidally modulated current and therefore it is more suitable for chaos encryption techniques. The synchronization characteristics and the communication performances of unidirectional coupled VCSEL driven by the broad frequency spectral bandwidth chaotic oscillators are investigated numerically. The results show that high-quality synchronization and transmission of messages can be realized for suitable system parameters. Chaos shift keying method is successfully applied to encrypt a message at a high bitrate.

Acceleration of laser-injected electron beams in an electron-beam driven plasma wakefield accelerator

International Nuclear Information System (INIS)

Knetsch, Alexander

2018-03-01

Plasma wakefields deliver accelerating fields that are approximately a 100 times higher than those in conventional radiofrequency or even superconducting radiofrequency cavities. This opens a transformative path towards novel, compact and potentially ubiquitous accelerators. These prospects, and the increasing demand for electron accelerator beamtime for various applications in natural, material and life sciences, motivate the research and development on novel plasma-based accelerator concepts. However, these electron beam sources need to be understood and controlled. The focus of this thesis is on electron beam-driven plasma wakefield acceleration (PWFA) and the controlled injection and acceleration of secondary electron bunches in the accelerating wake fields by means of a short-pulse near-infrared laser. Two laser-triggered injection methods are explored. The first one is the Trojan Horse Injection, which relies on very good alignment and timing control between electron beam and laser pulse and then promises electron bunches with hitherto unprecedented quality as regards emittance and brightness. The physics of electron injection in the Trojan Horse case is explored with a focus on the final longitudinal bunch length. Then a theoretical and numerical study is presented that examines the physics of Trojan Horse injection when performed in an expanding wake generated by a smooth density down-ramp. The benefits are radically decreased drive-electron bunch requirements and a unique bunch-length control that enables longitudinal electron-bunch shaping. The second laser-triggered injection method is the Plasma Torch Injection, which is a versatile, all-optical laser-plasma-based method capable to realize tunable density downramp injection. At the SLAC National Laboratory, the first proof-of-principle was achieved both for Trojan Horse and Plasma Torch injection. Setup details and results are reported in the experimental part of the thesis along with the commissioning

Consumer Innovativeness Model of Indonesian Young People in Adopting Electronic Products

Directory of Open Access Journals (Sweden)

Reza Ashari Nasution

2012-06-01

Full Text Available It is important for marketers to understand how innovators respond to the introduction of new products. This paper investigates consumer innovativeness (CI from meta-analysis study as suggested by Nasution and Garnida [2011] and examines the simultaneous impacts of CI on new product adoption. Nasution and Garnida [2010] proposed three different perspectives in conceptualizing the CI model. First, the generalist stream that represents a generalized personality trait that engenders consumers to adopt new product. Second, the particularist stream that focuses on product adoption behavior within a specific domain of interest. Third, the integrator perspective that proposes to integrate these two streams by putting domain-specific innovativeness as a mediating factor in relationship between general innovativeness trait and new product adoption.A structural equation model is used to test hypotheses using empirical data from 607 respondents in electronic products adoption. The result shows that the integrator perspective provides the best model in representing the empirical data. The finding of the integrator perspective reveals that domain specific CI mediates the relationship between general innovativeness trait and new product adoption. Specifically, subjective knowledge and hedonic idea shopping enhances the actuality of new products.The findings provide an explanation to the less than consistent relationship between consumer innovativeness and new product adoption. However, a single research context of electronic products and student sample may become one of the limitations and future studies needed to replicate the perspective of CI in different research contexts for greater generalizability and the use of non-student sample. The findings have implications for the innovation adoption theory, for managers involved in the introduction of new products, and for future research on innovation adoption.

Selection of high-brightness, laser-driven cathodes for electron accelerators and FELS

International Nuclear Information System (INIS)

Oettinger, P.E.

1987-01-01

Very intense, low emittance pulsed beams of electrons can be generated from laser-driven cathodes either by thermionic- or photo-emission. Several hundreds of amperes of electrons per square centimeter were observed for pulse lengths up to 50 ns. A normalized beam brightness of 10 7 A/cm 2 /rad 2 has been measured. These beams can be emission-gated at the cathode surface by modulating the laser-beam. Such beam bunching will generate picosecond-to-microsecond-long pulses at the source. A variety of cathodes are described, and a method of selection for specific applications is presented

2004-03-01

Nanotechnology is a revolutionary engine that will engender enormous changes in a vast majority of today's industries and markets, while potentially creating whole new industries. The impact of nanotechnology is particularly significant in the electronics industry, which is constantly driven by the need for higher performance, increased functionality, smaller size and lower cost. Nanotechnology can influence many of the hundreds of components that are typically assembled to manufacture modern electronic devices. Motorola manufactures electronics for a wide range of industries and communication products. In this presentation, the typical components of a cellular phone are outlined and technology requirements for future products, the customer benefits, and the potential impact of nanotechnology on many of the components are discussed. Technology needs include reliable materials supply, processes for high volume production, experimental and simulation tools, etc. For example, even routine procedures such as failure characterization may require the development of new tools for investigating nano-scale phenomena. Business needs include the development of an effective, high volume supply chain for nano-materials and devices, disruptive product platforms, and visible performance impact on the end consumer. An equally significant long-term industry need is the availability of science and engineering graduates with a multidisciplinary focus and a deep understanding of the fundamentals of nano-technology, that can harness the technology to create revolutionary products.

HD-DVD: the next consumer electronics revolution?

Science.gov (United States)

Topiwala, Pankaj N.

2003-11-01

The DVD is emerging as one of the world's favorite consumer electronics product, rapidly replacing analog videotape in the US and many other markets at prodigious rates. It is capable of offering a full feature-length, standard-definition movie in crisp rendition on TV. TV technology is itself in the midst of switching from analog to digital TV, with high-definition being the main draw. In fact, the US government has been advocating that switch over to digital TC, with both carrot and stick approaches, for nearly two decades, with only modest results--about 2% penetration. Under FCC herding, broadcasters are falling in the digital line--slowly, and sans profit. Meanwhile, delivery of HD content on portable media would be a great solution. Indeed, a new disk technology based on blue lasers is coming; but its widespread adoption may yet be four to five yeras away. But a promising new video codec--H.264/MPEG-4 AVC, the latest coding standard jointly developed by the Video Coding Experts Group (VCEG) of ITU-T and Moving Picture Experts Group (MPEG) of ISO/IEC, just might be the missing link. It offers substantial coding gains over MPEG-2, used in today's DVDs. With H.264, it appears possible to put HD movies on today's red-laser DVDs. Since consumers love DVDs, and HD--when they can see it, can H.264 and HD-DVD ignite a new revolution, now? It may have a huge impact on (H)DTV adoption rates.

Di Napoli-Davis, Gina; Owens, Janel E.

2013-01-01

Tetrabromobisphenol-A (TBBPA) is a brominated flame retardant used worldwide. Despite its widespread use, there are few data concerning environmental concentrations of TBBPA. Thus, the objective of this work was to optimize an ultrasound-assisted dispersed liquid-liquid microextraction (DLLME) method to analyze swabbed surfaces of consumer electronics to determine TBBPA concentrations. Upon sample preparation with DLLME, TBBPA was derivatized with acetic anhydride and then analyzed by gas chromatography–mass spectrometry (GC/MS). Using a 13 C 12 -TBBPA internal standard to improve precision and quantitation, a recovery study was performed. At concentrations of 250–1000 ng/mL, recoveries were 104–106%. Sample preparation with solid phase extraction had comparable recoveries, although overall, improved analyte recovery and precision were achieved with DLLME. In a small survey study, TBBPA concentrations in dust collected from 100 cm 2 areas on electronic surfaces (monitor, microwave, refrigerator, and TV) were determined to range from less than the LOQ to 523 ng/mL. -- Highlights: •Tetrabromobisphenol-A (TBBPA) concentrations in dust samples were determined. •Dust samples were collected from surfaces of consumer electronics. •Dispersed liquid-liquid microextraction was used to prepare samples for GC/MS. •A 13 C 12 -labeled internal standard was used to improve precision and quantitation. •TBBPA was found in dust samples at levels below LOQ to 523 ng/mL. -- This work describes the analysis of the brominated flame retardant, tetrabromobisphenol-A (TBBPA), from dust sampled on surfaces of consumer electronics

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is the first publicly reported nationwide survey to evaluate and compare hospitals. Increasing patient satisfaction is an important goal as it aims to achieve a more effective and efficient healthcare delivery system. In this study, we develop and apply an integrative, data-driven approach to identify clinical risk factors that associate with patient satisfaction outcomes. We included 1,771 unique adult patients who completed the HCAHPS survey and were discharged from the inpatient Medicine service from 2010 to 2012. We collected 266 clinical features including patient demographics, lab measurements, medications, disease categories, and procedures. We developed and applied a data-driven approach to identify risk factors that associate with patient satisfaction outcomes. We identify 102 significant risk factors associating with 18 surveyed questions. The most significantly recurrent clinical risk factors were: self-evaluation of health, education level, Asian, White, treatment in BMT oncology division, being prescribed a new medication. Patients who were prescribed pregabalin were less satisfied particularly in relation to communication with nurses and pain management. Explanation of medication usage was associated with communication with nurses (q = 0.001); however, explanation of medication side effects was associated with communication with doctors (q = 0.003). Overall hospital rating was associated with hospital environment, communication with doctors, and communication about medicines. However, patient likelihood to recommend hospital was associated with hospital environment, communication about medicines, pain management, and communication with nurse. Our study identified a number of putatively novel clinical risk factors for patient satisfaction that suggest new opportunities to better understand and manage patient satisfaction. Hospitals can use a data-driven approach to

Full Text Available Human resources represent one of the most important companies’ resources responsible in creation of companies’ competitive advantage. In search for the most valuable resources, companies use different methods. Lately, one of the growing methods is electronic recruiting, not only as a recruitment tool, but also as a mean of external communication. Additionally, in the process of corporate communication, companies nowadays use the electronic corporate communication as the easiest, the cheapest and the simplest form of business communication. The aim of this paper is to investigate relationship between three groups of different criteria; including main characteristics of performed electronic recruiting, corporate communication and selected financial performances. Selected companies were ranked separately by each group of criteria by usage of multicriteria decision making method PROMETHEE II. The main idea is to research whether companies which are the highest performers by certain group of criteria obtain the similar results regarding other group of criteria or performing results.

Communicating Sustainable Shoes to Mainstream Consumers: The Impact of Advertisement Design on Buying Intention

Mirjam Visser

2015-06-01

Full Text Available Traditionally, marketing of sustainable products addresses green buyers, thus missing out on the mainstream consumers and volume necessary to cover the potentially higher cost of more sustainable materials. However, how to effectively communicate more sustainable products to mainstream consumers and to increase their buying intention is still underexplored. Combining personal and environmental benefits, called double benefit theory, is promoted as an effective green marketing strategy but so far not supported by quantitative research as being effective to reach mainstream consumers. We studied the effect of advertisement elements (layout color, benefit type, and heritage on the products’ perceived sustainability, quality and fashion image, and buying intentions of mainstream consumers. Two hundred adults participated in a study that was based on a 2 (red vs. green layout × 2 (personal vs. environmental benefit × 2 (local vs. global heritage between-subjects factorial design of a sustainable shoe advertisement. The impact of these independent variables on product image as well as on buying intention was analyzed by means of three-way ANOVAs. In line with the double benefit theory, combining a personal benefit with a green layout led to the highest buying intention. Moreover, a mediation analysis revealed the effect of emphasizing a personal benefit on buying intention was mediated by fashion image but not by sustainability. Sustainability, however, did have a positive effect on buying intentions independent of benefit type.

Observations of electron phase-space holes driven during magnetic reconnection in a laboratory plasma

Science.gov (United States)

Fox, W.; Porkolab, M.; Egedal, J.; Katz, N.; Le, A.

2012-03-01

This work presents detailed experimental observations of electron phase-space holes driven during magnetic reconnection events on the Versatile Toroidal Facility. The holes are observed to travel on the order of or faster than the electron thermal speed, and are of large size scale, with diameter of order 60 Debye lengths. In addition, they have 3D spheroidal structure with approximately unity aspect ratio. We estimate the direct anomalous resistivity due to ion interaction with the holes and find it to be too small to affect the reconnection rate; however, the holes may play a role in reining in a tail of accelerated electrons and they indicate the presence of other processes in the reconnection layer, such as electron energization and electron beam formation.

2009-04-01

To review the literature on consumers' knowledge, attitudes and opinions of the use of generic medicines. A narrative review of studies conducted from 1970 to 2008 on consumers perceptions and views towards generic medicines was performed. An extensive literature search was undertaken using indexing services available at the authors' institution library. The following keywords were used for the search: brand, generic, multisource, medications, medicines, drugs, pharmaceuticals and consumers, customers, and patients. Electronic databases searched were Medline, Inside Web, ISI Web of Knowledge, Science Direct, Springer Link, JSTOR, Proquest, Ebsco Host and Google Scholar. These electronic databases were searched for full text papers published in English from 1970 to October 2008. Twenty studies were identified. Eleven were from the USA, four were from Europe, two were from Canada and one each was from Australia, Brazil and Malaysia. In general, consumers showed mixed reactions towards the use of generic medicines. This was evident from the divergence of views observed by country development level, consumers' socioeconomic characteristics, drug product characteristics, pharmaceutical reimbursement system, policy environment, contact with health care professionals, past experience with medications, and knowledge of the seriousness of a medical condition. Patient confidence and knowledge pertaining to generic medicines use have increased over the past four decades, especially in developed countries. Mass educational efforts, financial incentives, and greater communication among patients and health care professionals were seen as major drivers to the uptake of generic medicines among consumers.

František Dařena

2011-01-01

Full Text Available Due to the rapid spread of computer technologies into day-to-day lives many purchases or purchase-related decisions are made in the electronic environment of the Web. In order to handle information overload that is the result of the availability of many web-based stores, products and services, consumers use decision support aids that help with need recognition, information retrieval, filtering, comparisons and choice making. Decision support systems (DSS discipline spreads about 40 years back and was mostly focused on assisting managers. However, online environments and decision support in such environments bring new opportunities also to the customers. The focus on decision support for consumers is also not investigated to the large extent and not documented in the literature. Providing customers with well designed decision aids can lead to lower cognitive decision effort associated with the purchase decision which results in significant increase of consumer’s confidence, satisfaction, and cost savings. During decision making process the subjects can chose from several methods (optimizing, reasoning, analogizing, and creating, DSS types (data-, model-, communication-, document-driven, and knowledge-based and benefit from different modern technologies. The paper investigates popular customer decision making aids, such as search, filtering, comparison, ­e-negotiations and auctions, recommendation systems, social network systems, product design applications, communication support etc. which are frequently related to e-commerce applications. Results include the overview of such decision supporting tools, specific examples, classification according the way how the decisions are supported, and possibilities of applications of progressive technologies. The paper thus contributes to the process of development of the interface between companies and the customers where customer decisions take place.

Conceptual design of a bright electron injector for the 1 GeV high gradient test experiment, envisaged by the LLNL-SLAC-LBL collaboration on the Relativistic Klystron is presented. The design utilizes a high-brightness laser-driven rf photocathode electron gun, similar to the pioneering LANL early studies in concept (different parametrically however), together with achromatic magnetic bunching and transport systems and diagnostics. The design is performed with attention to possible use in an FEL as well. A simple but realistic analytic model including longitudinal and transverse space-charge and rf effects and extensive computer simulation form the basis of the parametric choice for the source. These parameters are used as guides for the design of the picosecond laser system and magnetic bunching section. 4 refs., 5 figs., 2 tabs

The aim of the study is to describe nursing professionals' experiences of the use of electronic devices for communication with colleagues and other healthcare professionals. Information and communication technology applications in health care are rapidly expanding, thanks to the fast-growing penetration of the Internet and mobile technology. Communication between professionals in health care is essential for patient safety and quality of care. Implementing new methods for communication among healthcare professionals is important. A cross-sectional survey was used in the study. The data were collected in spring 2012 using an electronic questionnaire with structured and open-ended questions. The target group comprised the nursing professionals (N = 567, n = 123) in one healthcare district who worked in outpatient clinics in publically funded health care in Finland. Nursing professionals use different electronic devices for communication with each other. The most often used method was email, while the least used methods were question-answer programmes and synchronous communication channels on the Internet. Communication using electronic devices was used for practical nursing, improving personnel competences, organizing daily operations and administrative tasks. Electronic devices may speed up the management of patient data, improve staff cooperation and competence and make more effective use of working time. The obstacles were concern about information security, lack of technical skills, unworkable technology and decreasing social interaction. According to our findings, despite the obstacles related to use of information technology, the use of electronic devices to support communication among healthcare professionals appears to be useful. © 2014 John Wiley & Sons Ltd.

Electronic waste recovery in Finland: Consumers' perceptions towards recycling and re-use of mobile phones.

Science.gov (United States)

Ylä-Mella, Jenni; Keiski, Riitta L; Pongrácz, Eva

2015-11-01

This paper examines consumers' awareness and perceptions towards mobile phone recycling and re-use. The results are based on a survey conducted in the city of Oulu, Finland, and analysed in the theoretical framework based on the theories of planned behaviour (TPB) and value-belief-norm (VBN). The findings indicate that consumers' awareness of the importance and existence of waste recovery system is high; however, awareness has not translated to recycling behaviour. The survey reveals that 55% of respondents have two or more unused mobile phones at homes. The more phones stored at homes, the more often reasons 'I don't know where to return' and/or 'have not got to do it yet' were mentioned. This indicates that proximity and the convenience of current waste management system are inadequate in promoting the return of small waste electrical and electronic equipment (WEEE). To facilitate re-use, and the highest level of recovery, consumers will need to be committed to return end-of-use electronics to WEEE collection centres without delays. Further, the supply and demand of refurbished mobile phones do not meet at this moment in Finland due to consumer's storing habits versus expectations of recent features under guarantee and unrealistic low prizes. The study also points out that, in order to change current storing habits of consumers, there is an explicit need for more information and awareness on mobile phone collection in Finland, especially on regarding retailers' take-back.

Bergmo, Trine Strand; Wangberg, Silje Camilla

2007-06-01

Despite the common use of electronic communication in other aspects of everyday life, its use between patients and health care providers has been slow to diffuse. Possible explanations are security issues and lack of payment mechanisms. This study investigated how patients value secure electronic access to their general practitioner (GP). One hundred and ninety-nine patients were asked an open-ended willingness-to-pay (WTP) question as part of a randomised controlled trial. We compared the WTP values between two groups of respondents; one group had had the opportunity to communicate electronically with their GP for a year and the other group had not. Fifty-two percent of the total sample was willing to pay for electronic GP contact. The group of patients with access revealed a significantly lower WTP than the group without such access. Possible explanations are that the system had fewer benefits than expected, a presence of hypothetical bias or simply a preference for face-to-face encounters.

Electronic and internet-based tools for patient-provider communication are becoming the standard of care, but disparities exist in their adoption among patients. The reasons for these disparities are unclear, and few studies have looked at the potential communication technologies have to benefit vulnerable patient populations. To characterize access to, interest in, and attitudes toward internet-based communication in an ethnically, economically, and linguistically diverse group of patients from a large urban safety net clinic network. Observational, cross-sectional study Adult patients (≥ 18 years) in six resource-limited community clinics in the San Francisco Department of Public Health (SFDPH) MAIN MEASURES: Current email use, interest in communicating electronically with health care professionals, barriers to and facilitators of electronic health-related communication, and demographic data-all self-reported via survey. Sixty percent of patients used email, 71 % were interested in using electronic communication with health care providers, and 19 % reported currently using email informally with these providers for health care. Those already using any email were more likely to express interest in using it for health matters. Most patients agreed electronic communication would improve clinic efficiency and overall communication with clinicians. A significant majority of safety net patients currently use email, text messaging, and the internet, and they expressed an interest in using these tools for electronic communication with their medical providers. This interest is currently unmet within safety net clinics that do not offer a patient portal or secure messaging. Tools such as email encounters and electronic patient portals should be implemented and supported to a greater extent in resource-poor settings, but this will require tailoring these tools to patients' language, literacy level, and experience with communication technology.

Capacity modulation of an inverter-driven multi-air conditioner using electronic expansion valves

International Nuclear Information System (INIS)

Choi, J.M.; Kim, Y.C.

2003-01-01

An inverter-driven multi-air conditioner provides the benefits of comfort, energy conservation and easy maintenance. Recently, the multi-air conditioner has been employed in small and medium-sized buildings. However, the performance data and control algorithm for multi-air conditioners are limited in literature due to complicated system parameters and operating conditions. In the present study, the performance of an inverter-driven multi-air conditioner having two indoor units with electronic expansion valves (EEV) was measured by varying indoor loads, EEV opening, and compressor speed. Based on the experimental results, the operating characteristics and capacity modulation of the inverter-driven multi-air conditioner are discussed. As a result, it is suggested that the superheats for both indoor units have to be maintained around 4 o C by utilizing the EEVs in this system, and consequently, the compressor speed needs to be adjusted to provide optimum cooling capacity for each indoor unit

We present the development of the first ultrafast transmission electron microscope (UTEM) driven by localized photoemission from a field emitter cathode. We describe the implementation of the instrument, the photoemitter concept and the quantitative electron beam parameters achieved. Establishing a new source for ultrafast TEM, the Göttingen UTEM employs nano-localized linear photoemission from a Schottky emitter, which enables operation with freely tunable temporal structure, from continuous wave to femtosecond pulsed mode. Using this emission mechanism, we achieve record pulse properties in ultrafast electron microscopy of 9 Å focused beam diameter, 200 fs pulse duration and 0.6 eV energy width. We illustrate the possibility to conduct ultrafast imaging, diffraction, holography and spectroscopy with this instrument and also discuss opportunities to harness quantum coherent interactions between intense laser fields and free-electron beams. - Highlights: • First implementation of an ultrafast TEM employing a nanoscale photocathode. • Localized single photon-photoemission from nanoscopic field emitter yields low emittance ultrashort electron pulses. • Electron pulses focused down to ~9 Å, with a duration of 200 fs and an energy width of 0.6 eV are demonstrated. • Quantitative characterization of ultrafast electron gun emittance and brightness. • A range of applications of high coherence ultrashort electron pulses is shown.

The Pavilion Lake Research Project (PLRP) is a unique platform where the combination of scientific research and human space exploration concepts can be tested in an underwater spaceflight analog environment. The 2015 PLRP field season was performed at Pavilion Lake, Canada, where science-driven exploration techniques focusing on microbialite characterization and acquisition were evaluated within the context of crew and robotic extravehicular activity (EVA) operations. The primary objectives of this analog study were to detail the capabilities, decision-making process, and operational concepts required to meet non-simulated scientific objectives during 5-minute one-way communication latency utilizing crew and robotic assets. Furthermore, this field study served as an opportunity build upon previous tests at PLRP, NASA Desert Research and Technology Studies (DRATS), and NASA Extreme Environment Mission Operations (NEEMO) to characterize the functional roles and responsibilities of the personnel involved in the distributed flight control team and identify operational constraints imposed by science-driven EVA operations. The relationship and interaction between ground and flight crew was found to be dependent on the specific scientific activities being addressed. Furthermore, the addition of a second intravehicular operator was found to be highly enabling when conducting science-driven EVAs. Future human spaceflight activities will need to cope with the added complexity of dynamic and rapid execution of scientific priorities both during and between EVA execution to ensure scientific objectives are achieved.

Accurately communicating patient data during daily ICU rounds is critically important since data provide the basis for clinical decision making. Despite its importance, high fidelity data communication during interprofessional ICU rounds is assumed, yet unproven. We created a robust but simple methodology to measure the prevalence of inaccurately communicated (misrepresented) data and to characterize data communication failures by type. We also assessed how commonly the rounding team detected data misrepresentation and whether data communication was impacted by environmental, human, and workflow factors. Direct observation of verbalized laboratory data during daily ICU rounds compared with data within the electronic health record and on presenters' paper prerounding notes. Twenty-six-bed academic medical ICU with a well-established electronic health record. ICU rounds presenter (medical student or resident physician), interprofessional rounding team. None. During 301 observed patient presentations including 4,945 audited laboratory results, presenters used a paper prerounding tool for 94.3% of presentations but tools contained only 78% of available electronic health record laboratory data. Ninty-six percent of patient presentations included at least one laboratory misrepresentation (mean, 6.3 per patient) and 38.9% of all audited laboratory data were inaccurately communicated. Most misrepresentation events were omissions. Only 7.8% of all laboratory misrepresentations were detected. Despite a structured interprofessional rounding script and a well-established electronic health record, clinician laboratory data retrieval and communication during ICU rounds at our institution was poor, prone to omissions and inaccuracies, yet largely unrecognized by the rounding team. This highlights an important patient safety issue that is likely widely prevalent, yet underrecognized.

Evidence for fast-electron-driven Alfvenic modes in the HSX stellarator

The helically-symmetric experiment (HSX) stellarator device is the first of a new generation of stellarators that exploit the concept of quasi-symmetric magnetic fields. In HSX, the plasma is both produced and heated by use of electron cyclotron resonance heating (ECRH) at the 2nd harmonic X-mode resonance. This heating configuration generates a nonthermal energetic electron population. Herein, we report on the first experimental evidence for fast-electron-driven Global Alfven Eigenmodes (GAE). This mode has previously been observed in both tokamaks and stellarators but it was always driven by energetic ions, not electrons. Evidence for this instability is obtained from quasi-helically symmetric HSX plasmas. Potential consequences of these measurements are twofold; (1) fast electrons can drive the GAE instability, and (2) quasi-symmetry makes a difference by better confining the particles that drive the instability as compared to the conventional stellarator configuration. We report on several features of this fluctuation. It is a coherent mode that is experimentally observed in the plasma core and edge by external magnetic coils, interferometry, ECE and Langmuir probes diagnostics. Fluctuations are observed in the frequency range of 20-120 kHz and scale with ion mass density according to expectations for Alfvenic modes. The mode is observed to be global with odd poloidal mode number (inferred from interferometry, possibly m=1) and is present in quasi-helically symmetric HSX plasmas. When quasi-helical symmetry is broken, the mode is no longer observed. Theory predicts a GAE mode in the gap below the Alfven continua can be excited in the frequency range of the measured fluctuations. By employing a biased electrode inserted deep into the plasma, flows can be generated. Under these conditions, the Alfvenic mode amplitude can increase and the fluctuation is even observed in the conventional stellarator configuration. Shifts in the measured frequency can be used to

Supersonic micro-jets and their application to few-cycle laser-driven electron acceleration

International Nuclear Information System (INIS)

Schmid, Karl

2009-01-01

This thesis covers the few-cycle laser-driven acceleration of electrons in a laser-generated plasma. The laser system employed in this work is a new development based on optical parametric chirped pulse amplification and is the only multi-TW few-cycle laser in the world. In the experiment, the laser beam is focused onto a supersonic helium gas jet which leads to the formation of a plasma channel. The laser pulse, having an intensity of 10 19 W/cm 2 propagates through the plasma with an electron density of 2 x 10 19 cm -3 and forms via a highly nonlinear interaction a strongly anharmonic plasma wave. The amplitude of the wave is so large that the wave breaks, thereby injecting electrons from the background plasma into the accelerating phase. The energy transfer from the laser pulse to the plasma is so strong that the maximum propagation distance is limited to the 100 m range. Therefore, gas jets specifically tuned to these requirements have to be employed. The properties of microscopic supersonic gas jets are thoroughly analyzed in this work. Based on numeric flow simulation, this study encompasses several extensive parameter studies that illuminate all relevant features of supersonic flows in microscopic gas nozzles. This allowed the optimized design of de Laval nozzles with exit diameters ranging from 150 μm to 3 mm. The employment of these nozzles in the experiment greatly improved the electron beam quality. After these optimizations, the laser-driven electron accelerator now yields monoenergetic electron pulses with energies up to 50 MeV and charges between one and ten pC. The electron beam has a typical divergence of 5 mrad and comprises an energy spectrum that is virtually free from low energetic background. The electron pulse duration could not yet be determined experimentally but simulations point towards values in the range of 1 fs. The acceleration gradient is estimated from simulation and experiment to be approximately 0.5 TV/m. The electron accelerator

The fast electron flux driven by Lower Hybrid Wave (LHW) in the scrape-off layer (SOL) in EAST is analyzed both theoretically and experimentally. The five bright belts flowing along the magnetic field lines in the SOL and hot spots at LHW guard limiters observed by charge coupled device and infrared cameras are attributed to the fast electron flux, which is directly measured by retarding field analyzers (RFA). The current carried by the fast electron flux, ranging from 400 to 6000 A/m 2 and in the direction opposite to the plasma current, is scanned along the radial direction from the limiter surface to the position about 25 mm beyond the limiter. The measured fast electron flux is attributed to the high parallel wave refractive index n || components of LHW. According to the antenna structure and the LHW power absorbed by plasma, a broad parallel electric field spectrum of incident wave from the antennas is estimated. The radial distribution of LHW-driven current density is analyzed in SOL based on Landau damping of the LHW. The analytical results support the RFA measurements, showing a certain level of consistency. In addition, the deposition profile of the LHW power density in SOL is also calculated utilizing this simple model. This study provides some fundamental insight into the heating and current drive effects induced by LHW in SOL, and should also help to interpret the observations and related numerical analyses of the behaviors of bright belts and hot spots induced by LHW

We discuss the design and current status of a compact free-electron laser (FEL), generating ultra-fast, high-peak flux, VUV pulses driven by a high-current, GeV electron beam from the existing Lawrence Berkeley National Laboratory (LBNL) laser-plasma accelerator, whose active acceleration length is only a few cm. The proposed ultra-fast source would be intrinsically temporally synchronized to the drive laser pulse, enabling pump-probe studies in ultra-fast science with pulse lengths of tens of fs. Owing to the high current ( and 10 kA) of the laser-plasma-accelerated electron beams, saturated output fluxes are potentially greater than 1013 photons/pulse. Devices based both on SASE and high-harmonic generated input seeds, to reduce undulator length and fluctuations, are considered

Laser-Driven Very High Energy Electron/Photon Beam Radiation Therapy in Conjunction with a Robotic System

Kazuhisa Nakajima

2014-12-01

Full Text Available We present a new external-beam radiation therapy system using very-high-energy (VHE electron/photon beams generated by a centimeter-scale laser plasma accelerator built in a robotic system. Most types of external-beam radiation therapy are delivered using a machine called a medical linear accelerator driven by radio frequency (RF power amplifiers, producing electron beams with an energy range of 6–20 MeV, in conjunction with modern radiation therapy technologies for effective shaping of three-dimensional dose distributions and spatially accurate dose delivery with imaging verification. However, the limited penetration depth and low quality of the transverse penumbra at such electron beams delivered from the present RF linear accelerators prevent the implementation of advanced modalities in current cancer treatments. These drawbacks can be overcome if the electron energy is increased to above 50 MeV. To overcome the disadvantages of the present RF-based medical accelerators, harnessing recent advancement of laser-driven plasma accelerators capable of producing 1-GeV electron beams in a 1-cm gas cell, we propose a new embodiment of the external-beam radiation therapy robotic system delivering very high-energy electron/photon beams with an energy of 50–250 MeV; it is more compact, less expensive, and has a simpler operation and higher performance in comparison with the current radiation therapy system.

Communicating Eco-Friendly Benefits: Why Accidental Improvements May Be Better Received by Consumers

Directory of Open Access Journals (Sweden)

Newman George E.

2016-05-01

Full Text Available Doing good does not necessarily imply doing well for a company. Ironically, in the case of green products it can even be quite the contrary. Deliberately enhancing a product with environmental benefits to make it more appealing may actually lead to a decrease in consumer interest because consumers suspect that quality was reduced on other dimensions. Even explicitly stating that the company cares about both the environment and quality is not sufficient to overcome consumers’ skepticism, according to our experiments. Fortunately, there are ways to communicate environmental improvements successfully. Companies improving a basic product feature like making something more eco-friendly should either position the improvement as unintended or emphasize that the primary goal is improving the quality of the product. Focusing on eco-conscious market segments also helps to avoid harm and might even be beneficial. Improvements on dimensions that are not inherent to a product’s composition, like fair trade or other social benefits, turned out to be less critical in the experiments.

In this letter we report the first clear experimental observation of density gradient stabilization of electron temperature gradient driven turbulence in a fusion plasma. It is observed that longer wavelength modes, k (perpendicular) ρ s ∼< 10, are most stabilized by density gradient, and the stabilization is accompanied by about a factor of two decrease in the plasma effective thermal diffusivity.

1999-08-01

A unified treatment of electron parametric instabilities driven by ultraintense laser light in plasma is described. It is valid for any intensity, polarization, plasma density, and scattering geometry. The method is applied to linearly polarized light in both underdense plasma and overdense plasma accessible by self-induced transparency. New options arise which are hybrids of stimulated Raman scattering, the two plasmon decay, the relativistic modulational and filamentation instabilities, and stimulated harmonic generation. There is vigorous growth over a wide range of wave numbers and harmonics.

Because of its wide distribution and ease of use, the mobile phone, as a reliable personal communications channel, offers an excellent basis for the provision of reliable electronic communications services. In Finland, ca. 75% of the citizens have a mobile phone and, at present and most likely also in the future, it is the most widely spread service channel allowing reliable electronic communications. Despite the restricted functions of the mobile phone, the citizens can use the phone also as a communications medium. In 2001, the Finns sent over 1 billion SMS messages. In Finland, TeliaSonera Finland Oyi and the Population Register Centre (PRC) have closed a co-operation agreement with the aim of creating a mobile phone service for the electronic identification of a person. The co-operation launched is a significant development project from the perspective of the citizens. As a result, the consumers will have a new alternative for reliable electronic communications and commerce in data networks in addition to the electronic identification card. In the future, it will be possible to use the services of both public administration and the private sector by means of a mobile phone more reliably than before, without a physical visit, e.g. to a health centre or to another provider of healthcare services. The possibility of identification and signature by a mobile phone allows an easier provision of versatile services irrespective of time and place, because, in addition to voice, text message, and WAP functions, the service can be utilised also in communications services through the Internet, in which case, the mobile phone acts like a card reader. From the perspective of reliable personal mobile communications, the healthcare sector is one of the most significant and challenging application areas.

The transition between acute care and community care can be a vulnerable period in a patients' treatment due to the potential for postdischarge adverse events. The vulnerability of this period has been attributed to factors related to the miscommunication between hospital-based and community-based physicians. Electronic discharge communication has been proposed as one solution to bridge this communication gap. Prior to widespread implementation of these tools, the costs and benefits should be considered. To establish the cost and cost-effectiveness of electronic discharge communications compared with traditional discharge systems for individuals who have completed care with one provider and are transitioning care to a new provider. We conducted a systematic review of the published literature, using best practices, to identify economic evaluations/cost analyses of electronic discharge communication tools. Inclusion criteria were: (1) economic analysis and (2) electronic discharge communication tool as the intervention. Quality of each article was assessed, and data were summarised using a component-based analysis. One thousand unique abstracts were identified, and 57 full-text articles were assessed for eligibility. Four studies met final inclusion criteria. These studies varied in their primary objectives, methodology, costs reported and outcomes. All of the studies were of low to good quality. Three of the studies reported a cost-effectiveness measure ranging from an incremental daily cost of decreasing average discharge note completion by 1 day of $0.331 (2003 Canadian), a cost per page per discharge letter of €9.51 and a dynamic net present value of €31.1 million for a 5-year implementation of the intervention. None of the identified studies considered clinically meaningful patient or quality outcomes. Economic analyses of electronic discharge communications are scarcely reported, and with inconsistent methodology and outcomes. Further studies are needed

A multi-scale numerical model based on hydrodynamic equations with semi-kinetic treatment of electrons is used to investigate the influence of dual frequency excitation on the effective electron energy distribution function (EEDF) in a radio-frequency driven atmospheric pressure plasma. It is found that variations of power density, voltage ratio, and phase relationship provide separate control over the electron density and the mean electron energy. This is exploited to directly influence both the phase dependent and time averaged effective EEDF. This enables tailoring the EEDF for enhanced control of non-equilibrium plasma chemical kinetics at ambient pressure and temperature.

1990-01-01

We derive the dispersion relations for both small and large-Δ' modes (m ≥ 2, and m = 1 modes, respectively) driven by anomalous electron viscosity. Under the assumption that the anomalous kinematic electron viscosity is comparable to the anomalous electron thermal diffusivity, we find that the viscous mode typically has a higher growth rate than the corresponding resistive mode. We compare computational results in cylindrical and toroidal geometries with theory and present some nonlinear results for viscous m = 1 modes in both circular and D-shaped boundaries and discuss their possible rile in fast sawtooth crashes. 30 ref., 5 figs., 1 tab

Nonequilibrium excitations and transport of Dirac electrons in electric-field-driven graphene

Science.gov (United States)

Li, Jiajun; Han, Jong E.

2018-05-01

We investigate nonequilibrium excitations and charge transport in charge-neutral graphene driven with dc electric field by using the nonequilibrium Green's-function technique. Due to the vanishing Fermi surface, electrons are subject to nontrivial nonequilibrium excitations such as highly anisotropic momentum distribution of electron-hole pairs, an analog of the Schwinger effect. We show that the electron-hole excitations, initiated by the Landau-Zener tunneling with a superlinear I V relation I ∝E3 /2 , reaches a steady state dominated by the dissipation due to optical phonons, resulting in a marginally sublinear I V with I ∝E , in agreement with recent experiments. The linear I V starts to show the sign of current saturation as the graphene is doped away from the Dirac point, and recovers the semiclassical relation for the saturated velocity. We give a detailed discussion on the nonequilibrium charge creation and the relation between the electron-phonon scattering rate and the electric field in the steady-state limit. We explain how the apparent Ohmic I V is recovered near the Dirac point. We propose a mechanism where the peculiar nonequilibrium electron-hole creation can be utilized in a infrared device.

SPAD electronics for high-speed quantum communications

Bienfang, Joshua C.; Restelli, Alessandro; Migdall, Alan

2011-01-01

We discuss high-speed electronics that support the use of single-photon avalanche diodes (SPADs) in gigahertz singlephoton communications systems. For InGaAs/InP SPADs, recent work has demonstrated reduced afterpulsing and count rates approaching 500 MHz can be achieved with gigahertz periodic-gating techniques designed to minimize the total avalanche charge to less than 100 fC. We investigate afterpulsing in this regime and establish a connection to observations using more conventional techniques. For Si SPADs, we report the benefits of improved timing electronics that enhance the temporal resolution of Si SPADs used in a free-space quantum key distribution (QKD) system operating in the GHz regime. We establish that the effects of count-rate fluctuations induced by daytime turbulent scintillation are significantly reduced, benefitting the performance of the QKD system.

To compare pharmaceutical spending and utilization in a consumer driven health plan (CDHP) with a three-tier pharmacy benefit design, and to examine whether the CDHP creates incentives to reduce pharmaceutical spending and utilization for chronically ill patients, generic or brand name drugs, and mail-order drugs. Retrospective insurance claims analysis from a large employer that introduced a CDHP in 2001 in addition to a point of service (POS) plan and a preferred provider organization (PPO), both of which used a three-tier pharmacy benefit. Difference-in-differences regression models were estimated for drug spending and utilization. Control variables included the employee's income, age, and gender, number of covered lives per contract, election of flexible spending account, health status, concurrent health shock, cohort, and time trend. Results. CDHP pharmaceutical expenditures were lower than those in the POS cohort in 1 year without differences in the use of brand name drugs. We find limited evidence of less drug consumption by CDHP enrollees with chronic illnesses, and some evidence of less generic drug use and more mail-order drug use among CDHP members. The CDHP is cost-neutral or cost-saving to both the employer and the employee compared with three-tier benefits with no differences in brand name drug use. © Health Research and Educational Trust.

Electron temperature gradient driven instability in the tokamak boundary plasma

Xu, X.Q.; Rosenbluth, M.N.; Diamond, P.H.

1992-01-01

A general method is developed for calculating boundary plasma fluctuations across a magnetic separatrix in a tokamak with a divertor or a limiter. The slab model, which assumes a periodic plasma in the edge reaching the divertor or limiter plate in the scrape-off layer(SOL), should provide a good estimate, if the radial extent of the fluctuation quantities across the separatrix to the edge is small compared to that given by finite particle banana orbit. The Laplace transform is used for solving the initial value problem. The electron temperature gradient(ETG) driven instability is found to grow like t -1/2 e γmt

Care team identification in the electronic health record: A critical first step for patient-centered communication.

Science.gov (United States)

Dalal, Anuj K; Schnipper, Jeffrey L

2016-05-01

Patient-centered communication is essential to coordinate care and safely progress patients from admission through discharge. Hospitals struggle with improving the complex and increasingly electronic conversation patterns among care team members, patients, and caregivers to achieve effective patient-centered communication across settings. Accurate and reliable identification of all care team members is a precursor to effective patient-centered communication and ideally should be facilitated by the electronic health record. However, the process of identifying care team members is challenging, and team lists in the electronic health record are typically neither accurate nor reliable. Based on the literature and on experience from 2 initiatives at our institution, we outline strategies to improve care team identification in the electronic health record and discuss potential implications for patient-centered communication.

Nowadays, consumers use the computer mediated communication to make purchase decisions on a large variety of products and services. Since health care services are archetypal by nature, consumers in this field are one of the most encountered users of electronic word-of-mouth. The objective of this paper is to explain and support the necessity of adopting a different qualitative method when electronic word of mouth is harnessed on health care dedicated forums, that is, netnography.

This study investigated the unique associations between electronic media communication (EMC) with friends and adolescent substance use (tobacco, alcohol, and cannabis), over and beyond the associations of face-to-face (FTF) interactions with friends and the average level of classroom substance use. Drawn from the cross-national 2009/2010 Health Behaviour in School-aged Children (HBSC) study in The Netherlands, 5,642 Dutch adolescents (Mage = 14.29) reported on their substance use, EMC, and FTF interactions. Two-level multilevel analyses (participants nested within classrooms) were run. Electronic media communication was positively associated with adolescent substance use, though significantly more strongly with alcohol (β = 0.15, SEβ = 0.02) than with tobacco (β = 0.05, SEβ = 0.02, t (5,180) = 3.33, p Electronic media communication was uniquely associated with substance use, predominantly with alcohol use. Thus, adolescents' EMC and other online behaviors should not be left unnoticed in substance use research and prevention programs.

In today’s digital age, consumers have become more active. Especially, the younger consumer generation - referred to as iBrains- are increasingly spreading their own product experiences across digital channels into the virtual world. Stimulus-response communication still has its place, but must be supplemented with interactive offers that enable a dialogue with consumers. Diverse communication channels must be utilized - analog as well as digital - in order to reach the young target groups. As consumers tend to be “always on”, they use different communication channels simultaneously, leading to continuous partial attention. Therefore, not only new channels are necessary but the entire communication style and design need to be adapted. It is not enough to simply make contact. Instead of thinking about shortening the message, creativity should be put into creatively combining different building blocks of communication.

A DC high-brightness laser driven photoemissive electron gun is being developed at Peking University, in order to produce 50-100 ps electron bunches of high quality. The gun consists of a photocathode preparation chamber and a DC acceleration cavity. Different ways of fabricating photocathodes, such as chemical vapor deposition, ion beam implantation and ion beam enhanced deposition, can be adopted. The acceleration gap is designed with the aid of simulation codes EGUN and POISSON. The laser system is a mode-locked Nd-YAG oscillator proceeded by an amplifier at 10 Hz repetition rate, which can deliver three different wavelengths (1064/532/266 nm). The combination of a superconducting cavity with the photocathode preparation chamber is also discussed in this paper.

Electrostatic models of electron-driven proton transfer across a lipid membrane

We present two models for electron-driven uphill proton transport across lipid membranes, with the electron energy converted to the proton gradient via the electrostatic interaction. In the first model, associated with the cytochrome c oxidase complex in the inner mitochondria membranes, the electrostatic coupling to the site occupied by an electron lowers the energy level of the proton-binding site, making proton transfer possible. In the second model, roughly describing the redox loop in a nitrate respiration of E. coli bacteria, an electron displaces a proton from the negative side of the membrane to a shuttle, which subsequently diffuses across the membrane and unloads the proton to its positive side. We show that both models can be described by the same approach, which can be significantly simplified if the system is separated into several clusters, with strong Coulomb interaction inside each cluster and weak transfer couplings between them. We derive and solve the equations of motion for the electron and proton creation/annihilation operators, taking into account the appropriate Coulomb terms, tunnel couplings, and the interaction with the environment. For the second model, these equations of motion are solved jointly with a Langevin-type equation for the shuttle position. We obtain expressions for the electron and proton currents and determine their dependence on the electron and proton voltage build-ups, on-site charging energies, reorganization energies, temperature, and other system parameters. We show that the quantum yield in our models can be up to 100% and the power-conversion efficiency can reach 35%.

First Observation of Laser-Driven Acceleration of Relativistic Electrons in a Semi-Infinite Vacuum Space

CERN Document Server

Plettner, Tomas; Colby, Eric R; Cowan, Benjamin; Sears, Chris M S; Siemann, Robert; Smith, Todd I; Spencer, James

2005-01-01

We have observed acceleration of relativistic electrons in vacuum driven by a linearly polarized laser beam incident on a thin gold-coated reflective boundary. The observed energy modulation effect follows all the characteristics expected for linear acceleration caused by a longitudinal electric field. As predicted by the Lawson-Woodward theorem the laser driven modulation only appears in the presence of the boundary. It shows a linear dependence with the strength of the electric field of the laser beam and also it is critically dependent on the laser polarization. Finally, it appears to follow the expected angular dependence of the inverse transition radiation process.

Recently, semiconducting nanofiber networks (NFNs) have been considered as one of the most promising platforms for large-area and low-cost electronics applications. However, the high contact resistance among stacking nanofibers remained to be a major challenge, leading to poor device performance and parasitic energy consumption. In this report, a controllable welding technique for NFNs was successfully demonstrated via a bioinspired capillary-driven process. The interfiber connections were well-achieved via a cooperative concept, combining localized capillary condensation and curvature-induced surface diffusion. With the improvements of the interfiber connections, the welded NFNs exhibited enhanced mechanical property and high electrical performance. The field-effect transistors (FETs) based on the welded Hf-doped In 2 O 3 (InHfO) NFNs were demonstrated for the first time. Meanwhile, the mechanisms involved in the grain-boundary modulation for polycrystalline metal-oxide nanofibers were discussed. When the high-k ZrO x dielectric thin films were integrated into the FETs, the field-effect mobility and operating voltage were further improved to be 25 cm 2 V -1 s -1 and 3 V, respectively. This is one of the best device performances among the reported nanofibers-based FETs. These results demonstrated the potencies of the capillary-driven welding process and grain-boundary modulation mechanism for metal-oxide NFNs, which could be applicable for high-performance, large-scale, and low-power functional electronics.

Metal/Polymer Based Stretchable Antenna for Constant Frequency Far-Field Communication in Wearable Electronics

KAUST Repository

Hussain, Aftab M.

2015-10-06

Body integrated wearable electronics can be used for advanced health monitoring, security, and wellness. Due to the complex, asymmetric surface of human body and atypical motion such as stretching in elbow, finger joints, wrist, knee, ankle, etc. electronics integrated to body need to be physically flexible, conforming, and stretchable. In that context, state-of-the-art electronics are unusable due to their bulky, rigid, and brittle framework. Therefore, it is critical to develop stretchable electronics which can physically stretch to absorb the strain associated with body movements. While research in stretchable electronics has started to gain momentum, a stretchable antenna which can perform far-field communications and can operate at constant frequency, such that physical shape modulation will not compromise its functionality, is yet to be realized. Here, a stretchable antenna is shown, using a low-cost metal (copper) on flexible polymeric platform, which functions at constant frequency of 2.45 GHz, for far-field applications. While mounted on a stretchable fabric worn by a human subject, the fabricated antenna communicated at a distance of 80 m with 1.25 mW transmitted power. This work shows an integration strategy from compact antenna design to its practical experimentation for enhanced data communication capability in future generation wearable electronics.

Development of functional requirements for electronic health communication: preliminary results from the ELIN project.

Science.gov (United States)

Christensen, Tom; Grimsmo, Anders

2005-01-01

User participation is important for developing a functional requirements specification for electronic communication. General practitioners and practising specialists, however, often work in small practices without the resources to develop and present their requirements. It was necessary to find a method that could engage practising doctors in order to promote their needs related to electronic communication. Qualitative research methods were used, starting a process to develop and study documents and collect data from meetings in project groups. Triangulation was used, in that the participants were organised into a panel of experts, a user group, a supplier group and an editorial committee. The panel of experts created a list of functional requirements for electronic communication in health care, consisting of 197 requirements, in addition to 67 requirements selected from an existing Norwegian standard for electronic patient records (EPRs). Elimination of paper copies sent in parallel with electronic messages, optimal workflow, a common electronic 'envelope' with directory services for units and end-users, and defined requirements for content with the possibility of decision support were the most important requirements. The results indicate that we have found a method of developing functional requirements which provides valid results both for practising doctors and for suppliers of EPR systems.

The Manchester Fly Facility: Implementing an objective-driven long-term science communication initiative.

Science.gov (United States)

Patel, Sanjai; Prokop, Andreas

2017-10-01

Science communication is increasingly important for scientists, although research, teaching and administration activities tend to eat up our time already, and budgets for science communication are usually low. It appears impossible to combine all these tasks and, in addition, to develop engagement activities to a quality and impact that would make the efforts worth their while. Here we argue that these challenges are easier addressed when centering science communication initiatives on a long-term vision with a view to eventually forming outreach networks where the load can be shared whilst being driven to higher momentum. As one example, we explain the science communication initiative of the Manchester Fly Facility. It aims to promote public awareness of research using the model organism Drosophila, which is a timely, economic and most efficient experimental strategy to drive discovery processes in the biomedical sciences and must have a firm place in the portfolios of funding organisations. Although this initiative by the Manchester Fly Facility is sustained on a low budget, its long-term vision has allowed gradual development into a multifaceted initiative: (1) targeting university students via resources and strategies for the advanced training in fly genetics; (2) targeting the general public via science fairs, educational YouTube videos, school visits, teacher seminars and the droso4schools project; (3) disseminating and marketing strategies and resources to the public as well as fellow scientists via dedicated websites, blogs, journal articles, conference presentations and workshops - with a view to gradually forming networks of drosophilists that will have a greater potential to drive the science communication objective to momentum and impact. Here we explain the rationales and implementation strategies for our various science communication activities - which are similarly applicable to other model animals and other areas of academic science - and share our

How consumers evaluate eWOM (electronic word-of-mouth) messages.

Science.gov (United States)

Doh, Sun-Jae; Hwang, Jang-Sun

2009-04-01

This experiment explored how consumers evaluate electronic word-of-mouth (eWOM) messages about products. Each participant was exposed a 10-message set in a single board. Five groups were manipulated in terms of their ratios of positive and negative messages. The result showed significant differences across various sets of eWOM messages. Although more positive sets showed higher scores in many cases, this was not true in all situations, especially for the case of credibility. Involvement and prior knowledge partially moderated the relationship between the ratio of messages and the eWOM effect. The credibility of Web sites and eWOM messages can be damaged in the long run if all of the eWOM messages are positive.

Electronic Support Groups: An Open Line of Communication in Contested Illness.

Science.gov (United States)

Murphy, Michael; Kontos, Nicholas; Freudenreich, Oliver

Patients with functional somatic syndromes are often difficult to treat. The relationship between doctors and patients can be strained, which limits communication. Instead, patients often communicate with each other over the Internet in electronic support groups. This perspective summarizes studies of patient-to-patient communication over the Internet and uses the concept of contested illness to provide insights into the experiences of patients with functional somatic disorders. Conflict between a patient and their physician is a key feature of functional somatic syndromes. Physicians and patients do not have a shared understanding or appreciation of the patient's experiences. Patients with functional somatic syndromes often value their own embodied experience over medical knowledge. At the same time, they remain deeply invested in finding a "good doctor" who believes that the patient is suffering, agrees with their conception of the cause, and assents to the treatment as directed by the patient. Electronic support groups reinforce these beliefs. Patients may benefit from a compromising, collaborative approach that is realistic about the limitations of medical knowledge. However, physicians should not engage in unsafe treatment practices. Electronic support groups exist for a wide range of illnesses and the issues that rise to the surface in functional somatic syndromes likely occur to some extent with almost every patient.

Trapped Electron Mode Turbulence Driven Intrinsic Rotation in Tokamak Plasmas

International Nuclear Information System (INIS)

Wang, W.X.; Hahm, T.S.; Ethier, S.; Zakharov, L.E.

2011-01-01

Recent progress from global gyrokinetic simulations in understanding the origin of intrinsic rotation in toroidal plasmas is reported with emphasis on electron thermal transport dominated regimes. The turbulence driven intrinsic torque associated with nonlinear residual stress generation by the fluctuation intensity and the intensity gradient in the presence of zonal flow shear induced asymmetry in the parallel wavenumber spectrum is shown to scale close to linearly with plasma gradients and the inverse of the plasma current. These results qualitatively reproduce empirical scalings of intrinsic rotation observed in various experiments. The origin of current scaling is found to be due to enhanced kll symmetry breaking induced by the increased radial variation of the safety factor as the current decreases. The physics origin for the linear dependence of intrinsic torque on pressure gradient is that both turbulence intensity and the zonal flow shear, which are two key ingredients for driving residual stress, increase with the strength of turbulence drive, which is R0/LTe and R0/Lne for the trapped electron mode.

Traditional food products (TFP) are an important part of European culture, identity, and heritage. In order to maintain and expand the market share of TFP, further improvement in safety, health, or convenience is needed by means of different innovations. The aim of this study was to obtain a consumer-driven definition for the concept of TFP and innovation and to compare these across six European countries (Belgium, France, Italy, Norway, Poland and Spain) by means of semantic and textual statistical analyses. Twelve focus groups were performed, two per country, under similar conditions. The transcriptions obtained were submitted to an ordinary semantic analysis and to a textual statistical analysis using the software ALCESTE. Four main dimensions were identified for the concept of TFP: habit-natural, origin-locality, processing-elaboration and sensory properties. Five dimensions emerged around the concept of innovation: novelty-change, variety, processing-technology, origin-ethnicity and convenience. TFP were similarly perceived in the countries analysed, while some differences were detected for the concept of innovation. Semantic and statistical analyses of the focus groups led to similar results for both concepts. In some cases and according to the consumers' point of view the application of innovations may damage the traditional character of TFP.

Recording, handling and sharing healthcare information is important in order to ensure high quality of delivered healthcare. Information and communication technology (ICT may be a valuable tool for handling these challenges. One way of enhancing the exchange of information could be to establish a link between patient-specific and general information sent to the general practitioner (GP. The aim of the present paper is to study GPs' use of a hyperlink inserted into electronic test result communication. Methods We inserted a hyperlink into the electronic test result communication sent to the patients’ GPs who participated in a regional, systematic breast cancer screening program.

Promoting communication, participation, and learning with regard to organic food products: a communication theoretical approach

Directory of Open Access Journals (Sweden)

Peter Kastberg

2015-03-01

Full Text Available The market for organic foods is growing, however, the proportion of consumers buying organic foods is still considered low. Research shows that a significant barrier to consumers purchasing more organic foods is lack of information. This leads the relevant body of research to call for better communication around organic foods. The same body of research, however, neither questions what good communication surrounding organic foods is, nor what would make it better. Applying the communication theoretical formats of transmission, interaction, and coaction, respectively, onto instances of organic communication activities, I will discuss to what extent each format encourages consumer participation and learning. Transmission, typically in the form of monologuous mass communication, is cost effective. It is also a format that bars a sender, e.g., producer or farmer, from gauging deposits in the consumer, e.g., understanding the message, trusting the sender, etc. Interaction, typically in the form of dialoguous encounters, integrates feedback into communication allowing the sender to appreciate the level of understanding, trust, etc., which the communicative effort has given rise to, albeit at a higher price in terms of money, time, and manpower. In the format of coaction, typically in the form of co-operative endeavors, the deposit is a matter of what is coconstructed by the participants, e.g., understanding, trust, etc. Coaction thus satisfies the organic communicators craving for involving the consumer, and because food is a low-involvement commodity, this is critical. But emancipating the consumer comes at a price. First of all, coactional communication is dependent on highly motivated participants, and second, coactional communication is difficult if not impossible to control. Informed by these insights, I present an in-depth, critical discussion of the promises and pitfalls of how multicriteria assessments may be communicated and coconstructed on a

Huete-Alcocer, Nuria

2017-01-01

The rise and spread of the Internet has led to the emergence of a new form of word of mouth (WOM): electronic word of mouth (eWOM), considered one of the most influential informal media among consumers, businesses, and the population at large. Drawing on these ideas, this paper reviews the relevant literature, analyzing the impact of traditional WOM and eWOM in the field of consumer behavior and highlighting the main differences between the two types of recommendations, with a view to contributing to a better understanding of the potential of both.

Ambrose, Sophie E; VanDam, Mark; Moeller, Mary Pat

2014-01-01

The objectives of this study were to examine the quantity of adult words, adult-child conversational turns, and electronic media in the auditory environments of toddlers who are hard of hearing (HH) and to examine whether these factors contributed to variability in children's communication outcomes. Participants were 28 children with mild to severe hearing loss. Full-day recordings of children's auditory environments were collected within 6 months of their second birthdays by using Language ENvironment Analysis technology. The system analyzes full-day acoustic recordings, yielding estimates of the quantity of adult words, conversational turns, and electronic media exposure in the recordings. Children's communication outcomes were assessed via the receptive and expressive scales of the Mullen Scales of Early Learning at 2 years of age and the Comprehensive Assessment of Spoken Language at 3 years of age. On average, the HH toddlers were exposed to approximately 1400 adult words per hour and participated in approximately 60 conversational turns per hour. An average of 8% of each recording was classified as electronic media. However, there was considerable within-group variability on all three measures. Frequency of conversational turns, but not adult words, was positively associated with children's communication outcomes at 2 and 3 years of age. Amount of electronic media exposure was negatively associated with 2-year-old receptive language abilities; however, regression results indicate that the relationship was fully mediated by the quantity of conversational turns. HH toddlers who were engaged in more conversational turns demonstrated stronger linguistic outcomes than HH toddlers who were engaged in fewer conversational turns. The frequency of these interactions was found to be decreased in households with high rates of electronic media exposure. Optimal language-learning environments for HH toddlers include frequent linguistic interactions between parents and

High incidence and prevalence of type 2 diabetes require urgent attention to the management of this chronic disease. The purpose of this study was to explore electronic communication (e-communication) between patients with type 2 diabetes and their providers within the patient portal. Qualitative design with conventional content analysis techniques was used. A purposive random sample of 90 electronic medical record charts of patient-portal users with type 2 diabetes was subjected to a retrospective review. The sample mainly consisted of patients between the ages of 50 and 70 years, who were white, non-Hispanic, and English-speaking. The three major themes that emerged in e-communication via patient portal were inform theme, which was the most frequently identified theme; instruct/request theme, which was mainly used in initiation of e-communication; and the question theme. The patient portal was used primarily for requests by patients and instruction by providers, showing relatively short e-message encounters with a high number of partially completed encounters, frequent lack of resolution, and a low level of involvement of diabetes specialists in e-communication. There is a need to revise healthcare system guidelines on initiation and use of e-communication via patient portal and develop standardized templates to promote diabetes education in type 2 diabetes.

2017-12-01

Full Text Available The axiom “unseen – unsold” implies that marketing communication cannot be effective if it does not bypass the filter of attention, which is difficult in today’s information clutter. As internet has emerged as powerful channel for marketing communication, the same axiom applies to the online marketing communication. In this research the analysis and synthesis of scientific literature as well as two eye tracking experiments are applied for the analysis of internet context-related elements influencing consumer visual attention and as a consequence having influence on consumer behavior. As a result, the guidelines for the selection of advertising message-related factors and advertisement’s position in the internet news portals are provided. Moreover, recommendations for the attraction of consumer visual attention in the search engines are presented.

Perceived importance and responsibility for market-driven pig welfare

DEFF Research Database (Denmark)

Thorslund, Cecilie Agnete H; Aaslyng, Margit Dall; Lassen, Jesper

2017-01-01

This review explores barriers and opportunities for market-driven pig welfare in Europe. It finds, first, that consumers generally rank animal welfare as important, but they also rank it low relative to other societal problems. Second, consumers have a wide range of concerns about pig welfare......, but they focus especially on naturalness. Third, pig welfare is seen as an important indicator of meat quality. Fourth, consumers tend to think that responsibility for pig welfare lies with several actors: farmers, governments and themselves. The paper concludes that there is an opportunity for the market......-driven strategy to sell a narrative about naturalness supplemented with other attractive qualities (such as eating quality). It also emphasizes that pig welfare needs to be on the political/societal agenda permanently if it is to be viewed as an important issue by consumers and if consumers are to assume some...

Acceleration of electrons using laser-driven dielectric microstructures is a promising technology for the miniaturization of particle accelerators. In this work, experimental results are presented of relativistic electron acceleration with 690±100 MVm^-1 gradient. This is a record-high accelerating gradient for a dielectric microstructure accelerator, nearly doubling the previous record gradient. To reach higher acceleration gradients the present experiment employs 90 fs duration laser pulses.

Both doctors and consumers have engaged in using social media for health purposes. Social media has changed traditional one-to-one communication between doctors and patients to many-to-many communication between doctors and consumers. However, little is known about the effect of doctor-consumer interaction on consumers' health behaviors. The aim of this study was to investigate how doctor-consumer interaction in social media affects consumers' health behaviors. On the basis of professional-client interaction theory and social cognitive theory, we propose that doctor-consumer interaction can be divided into instrumental interaction and affective interaction. These two types of interactions influence consumers' health behaviors through declarative knowledge (DK), self-efficacy (SE), and outcome expectancy (OE). To validate our proposed research model, we employed the survey method and developed corresponding measurement instruments for constructs in our research model. A total of 352 valid answers were collected, and partial least square was performed to analyze the data. Instrumental doctor-consumer interaction was found to influence consumers' DK (t 294 =5.763, Pinteraction also impacted consumers' DK (t 294 =4.025, Pinteraction on health behaviors, whereas the three mediators fully mediated the effect of affective interaction on health behaviors. Compared with many intentional intervention programs, doctor-consumer interaction can be treated as a natural cost-effective intervention to promote consumers' health behaviors. Meanwhile, both instrumental and affective interaction should be highlighted for the best interaction results. DK, SE, and OE are working mechanisms of doctor-consumer interaction. ©Tailai Wu, Zhaohua Deng, Zhanchun Feng, Darrell J Gaskin, Donglan Zhang, Ruoxi Wang.

A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

THz cavities and injectors for compact electron acceleration using laser-driven THz sources

Moein Fakhari

2017-04-01

Full Text Available We present a design methodology for developing ultrasmall electron injectors and accelerators based on cascaded cavities excited by short multicycle THz pulses obtained from laser-driven THz generation schemes. Based on the developed concept for optimal coupling of the THz pulse, a THz electron injector and two accelerating stages are designed. The designed electron gun consists of a four cell cavity operating at 300 GHz and a door-knob waveguide to coaxial coupler. Moreover, special designs are proposed to mitigate the problem of thermal heat flow and induced mechanical stress to achieve a stable device. We demonstrated a gun based on cascaded cavities that is powered by only 1.1 mJ of THz energy in 300 cycles to accelerate electron bunches up to 250 keV. An additional two linac sections can be added with five and four cell cavities both operating at 300 GHz boosting the bunch energy up to 1.2 MeV using a 4-mJ THz pulse.

The highlights of recently observed electron emission from electronically excited sexual hormones (17{beta}-estradiol, progesterone, testosterone) and the phytohormone genistein in polar media are briefly reviewed. The electron yield, Q(e{sub aq}{sup -}), dependence from substrate concentration, hormone structure, polarity of solvent, absorbed energy and temperature are discussed. The hormones reactivity with e{sub aq}{sup -} and efficiency in electron transfer ensure them the ability to communicate with other biological systems in an organism. A hypothesis is presented for the explanation of the mechanisms of the distinct recognition of signals transmitted by electrons, originating from different types of hormones to receiving centres. Biological consequences of the electron emission in respect to cancer are mentioned.

Nonlinear structure formation in ion-temperature-gradient (ITG) driven waves is investigated in pair-ion plasma comprising ions and nonthermal electrons (kappa, Cairns). By using the transport equations of the Braginskii model, a new set of nonlinear equations are derived. A linear dispersion relation is obtained and discussed analytically as well as numerically. It is shown that the nonthermal population of electrons affects both the linear and nonlinear characteristics of the ITG mode in pair-ion plasma. This work will be useful in tokamaks and stellarators where non-Maxwellian population of electrons may exist due to resonant frequency heating, electron cyclotron heating, runaway electrons, etc.

In the advanced cancer context, care coordination is often inadequate, leading to suboptimal continuity of care. We evaluated an electronic web-based tool which assembles the patient, their caregivers, and their healthcare providers in a virtual space for team-based communication. We sought to understand participant perceptions on electronic communication in general and the added value of the new tool in particular. We conducted a qualitative descriptive study with participants (patients, caregivers, cancer physicians) who participated in a 3-month pilot trial evaluating the tool. Interviews were thematically analyzed and the perspectives from patients, caregivers, and cancer physicians were triangulated. Interviews from six patients, five of their caregivers, and seven cancer physicians conducted alongside monthly outcome assessments were analyzed. We identified five themes relating participants' perspectives on electronic communication to their experience of care: (1) apparent gaps in care, (2) uncertainty in defining the circle of care, (3) relational aspects of communication, (4) incongruence between technology and social norms of patient-physician communication, and (5) appreciation but apprehension about the team-based communication tool for improving the experience of care. The potential of tools for electronic communication to bring together a team of healthcare providers with the patient and caregivers is significant but may pose new challenges to existing team structure and interpersonal dynamics. Patients and physicians were worried about the impact that electronic communication may have on the patient-physician relationship. Implementation approaches, which build on the relationship and integrate the team as a whole, could positively position electronic communication to enhance the team-based care.

Full Text Available One-dimensional open-boundary simulations have been carried out in a current-carrying plasma seeded with a neutral density depression and with no initial electric field. These simulations show the development of a variety of nonlinear localized electric field structures: double layers (unipolar localized fields, fast electron phase-space holes (bipolar fields moving in the direction of electrons accelerated by the double layer and trains of slow alternating electron and ion phase-space holes (wave-like fields moving in the direction of ions accelerated by the double layer. The principal new result in this paper is to show by means of a linear stability analysis that the slow-moving trains of electron and ion holes are likely to be the result of saturation via trapping of a kinetic-Buneman instability driven by the interaction of accelerated ions with unaccelerated electrons.

Previous research describing consumers' communication behaviors in response to direct-to-consumer advertising (DTCA) suggests a social cognitive rationale to explain DTCA-related communication behavior. Guided by social cognitive theory, the objective of this study was to explore outcome expectancy and self-efficacy beliefs as predictors of individuals' intentions to communicate with their physicians about an advertised drug. One hundred and seven female college students completed a questionnaire, read an advertisement for an oral contraceptive drug, and completed a second questionnaire. The questionnaires assessed participants' self-efficacy and outcome expectancy beliefs, intended communication behavior, and demographic information. Pearson product-moment correlation analyses showed that outcome expectancy (r=0.75, Pbehavior (B=1.56, Padvertised drug [t(106)=14.75, Pconsumers' plans for interacting with physicians in response to DTCA. Health care providers can use these results to guide communication with patients regarding DTCA and meet patients' drug-related informational expectations.

The abundance of health information available online provides consumers with greater access to information pertinent to the management of health conditions. This is particularly important given an increasing drive for consumer-focused health care models globally, especially in the management of chronic health conditions, and in recognition of challenges faced by lay consumers with finding, understanding, and acting on health information sourced online. There is a paucity of literature exploring the navigational needs of consumers with regards to accessing online health information. Further, existing interventions appear to be didactic in nature, and it is unclear whether such interventions appeal to consumers' needs. Our goal was to explore the navigational needs of consumers with chronic health conditions in finding online health information within the broader context of consumers' online health information-seeking behaviors. Potential barriers to online navigation were also identified. Semistructured interviews were conducted with adult consumers who reported using the Internet for health information and had at least one chronic health condition. Participants were recruited from nine metropolitan community pharmacies within Western Australia, as well as through various media channels. Interviews were audio-recorded, transcribed verbatim, and then imported into QSR NVivo 10. Two established approaches to thematic analysis were adopted. First, a data-driven approach was used to minimize potential bias in analysis and improve construct and criterion validity. A theory-driven approach was subsequently used to confirm themes identified by the former approach and to ensure identified themes were relevant to the objectives. Two levels of analysis were conducted for both data-driven and theory-driven approaches: manifest-level analysis, whereby face-value themes were identified, and latent-level analysis, whereby underlying concepts were identified. We conducted 17

To determine who chooses a Consumer-Driven Health Plan (CDHP) in a multiplan, multiproduct setting, and, specifically, whether the CDHP attracts the sicker employees in a company's risk pool. We estimated a health plan choice equation for employees of the University of Minnesota, who had a choice in 2002 of a CDHP and three other health plans--a traditional health maintenance organization (HMO), a preferred provider organization (PPO), and a tiered network product based on care systems. Data from an employee survey were matched to information from the university's payroll system. Chronic illness of the employee or family members had no effect on choice of the CDHP, but such employees tended to choose the PPO. The employee's age was not related to CDHP choice. Higher-income employees chose the CDHP, as well as those who preferred health plans with a national provider panel that includes their physician in the panel. Employees tended to choose plans with lower out-of-pocket premiums, and surprisingly, employees with a chronic health condition themselves or in their family were more price-sensitive. This study provides the first evidence on who chooses a CDHP in a multiplan, multiproduct setting. The CDHP was not chosen disproportionately by the young and healthy, but it did attract the wealthy and those who found the availability of providers more appealing. Low out-of-pocket premiums are important features of health plans and in this setting, low premiums appeal to those who are less healthy.

Internet as a new communication, retail and distribution channel for young consumers

Full Text Available Marketing aspects of the Internet can be examined through a great number of researches on marketing practices conducted via the Internet. A number of authors consider the Internet as new marketplace (marketspace, where the exchange of both traditional and new values (i.e. digital products and services takes place. The Internet supports almost all aspects of a company’s business activities and can be applied with respect to all the elements of marketing mix. The subject of this paper is the role of adoption and use of the Internet as a new communication, retail and distribution channel for young consumers. The research was conducted in January 2006 and included 869 students from nine faculties at the University of Zagreb. Students represent an important marketing segment for Internet marketing activities since they are considered to be advanced users of the Internet. The relevance of students’ Internet adoption and use is determined by the following reasons: students are consumers; senior students will soon become young employed professionals with their own income (their spending will increase rapidly; in the near future, senior students will, to some extent, be decision makers on the implementation of business activities via the Internet. Research results show that students actively use the Internet, primarily as a communication channel. The student use of the Internet for purchasing tangible products is rare but their use of services via the Internet is considerable. Students find using the Internet to be a non-complex activity. There is no significant difference in the perception of complexity of the Internet usage among respondents with different computer and English language skills or with respect to their majoring fields (Arts, Biomedicine, Biotechnology, Engineering, Humanities, Natural and Social Sciences. A perception of the complexity of product purchase and service usage via the Internet is influenced by the experience that

Patient-provider electronic communication has proliferated in recent years, yet there is a dearth of published research either leading to, or including, recommendations that improve clinical care and prevent unintended negative consequences. We critically appraise published guidelines and suggest an agenda for future work in this area. To understand how existing guidelines align with current practice, evidence, and technology. We performed a narrative review of provider-targeted guidelines for electronic communication between patients and providers, searching Ovid MEDLINE, Embase, and PubMed databases using relevant terms. We limited the search to articles published in English, and manually searched the citations of relevant articles. For each article, we identified and evaluated the suggested practices. Across 11 identified guidelines, the primary focus was on technical and administrative concerns, rather than on relational communication. Some of the security practices recommended by the guidelines are no longer needed because of shifts in technology. It is unclear the extent to which the recommendations that are still relevant are being followed. Moreover, there is no guideline-cited evidence of the effectiveness of the practices that have been proposed. Our analysis revealed major weaknesses in current guidelines for electronic communication between patients and providers: the guidelines appear to be based on minimal evidence and offer little guidance on how best to use electronic tools to communicate effectively. Further work is needed to systematically evaluate and identify effective practices, create a framework to evaluate quality of communication, and assess the relationship between electronic communication and quality of care.

Role of Marketing Communication in a Company: Lumar Case Study

Full Text Available Marketing communication is an integral part of the famous 4-P. It plays an important role in the company, as it helps to increase company’s visibility and strengthen its brand. Marketing communication is achieving its objectives in communicating with customers and consumers using its marketing communication tools. If a company wants to be ahead of the competition, and have a good look in costumers’ ayes, marketing communication is most crucial. In this paper we analyze the case of marketing communication company Lumar. The results obtained argue that the company is well known, where we recognize especially the electronic media as most important tool of marketing communication. However, we noticed that the brand recognized more regionally – especially in Styria and Carinthia, despite the fact that the company is well known and active in all regions in Slovenia and abroad (Italy, Germany, Austria.

Unique Intramolecular Electronic Communications in Mono-ferrocenylpyrimidine Derivatives: Correlation between Redox Properties and Structural Nature

International Nuclear Information System (INIS)

Highlights: • Unique intramolecular electronic communications (electron withdrawing and π-bond delocalization effects) exist in the mono-ferrocenylpyrimidine derivatives. • The redox potential shift correlates the pyrimidine ring torsion angle with the extent of electron delocalization. • The correlation between redox properties and structural nature in mono-ferrocenylpyrimidine derivatives is evident. - Abstract: The correlation between redox properties and structural nature in a complete set of mono-ferrocenylpyrimidine derivatives (2-ferrocenylpyrimidine, 2-FcPy; 4-ferrocenylpyrimidine, 4-FcPy; 5-ferrocenylpyrimidine, 5-FcPy) was evaluated by investigating the intramolecular electronic communications. Both conventional electrochemical measurements in organic solvents and thin-film voltammetric studies of these compounds were carried out. It was discovered that their formal potentials are significantly different from each other, and shift negatively in the order of 4-FcPy > 5-FcPy > 2-FcPy. This result suggests that the intramolecular electronic communication is dictated by the delocalization effect of the π-bonding systems in 2-FcPy, and that the electron-withdrawing effect of the nitrogen atoms in the pyrimidine ring plays the key role in 4-FcPy and 5-FcPy. The single crystal X-ray structure analyis and Density Functional Theory (DFT) calculation provided additional evidence (e.g., different torsion angles between the cyclopentadienyl and pyrimidine rings) to support the observed correlation between the redox properties and structural nature

Consumer-driven health plans: latest challenge to practices' cash flow.

CDHPs are here to stay. Employers welcome CDHPs because they drive costs away from themselves and into the hands of both consumers and provides. The consumer will make medical purchase decisions tempered by personal economic considerations. The providers are left to figure it all out with the hope their cash flow, cost budgets, and customer service will not be negatively impacted. It will not be easy. Practices must become educated on how CDHPs work, become knowledgeable about specific HSA scenarios in their market, develop optimum processes and procedures, and train staff.

We report on the first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam. Strong magnetic fields (≥1 T ) are measured, via means of a proton radiography technique, after the propagation of a neutral electron-positron beam through a background electron-ion plasma. The experimentally determined equipartition parameter of ɛB≈10-3 is typical of values inferred from models of astrophysical gamma-ray bursts, in which the relativistic flows are also expected to be pair dominated. The data, supported by particle-in-cell simulations and simple analytical estimates, indicate that these magnetic fields persist in the background plasma for thousands of inverse plasma frequencies. The existence of such long-lived magnetic fields can be related to analog astrophysical systems, such as those prevalent in lepton-dominated jets.

Food quality and the consumers

Executive Summary: 1. Consumers and professionals in the food sector will differ in the way they view food quality. Professionals have knowledge and resources to establish quality based on objective criteria. Consumers lack both, and they are typically concerned with many different products...... resources, of means of transportation, of time, of knowledge. Consumers' shopping behaviour is therefore an imperfect indicator of the quality consumers want, insufficient way of communicating consumer wishes to the food sector. 3. The fact that the food producer may be separated from the consumer...... certain attributes of food products or materials which may contradict consumer intentions. Economic pressure to reduce costs may lead to deteriorating quality. 5. While the information supplied by the market may be enough to give feed back on products launched based on the trial-and-error method...

Narrative reports from electronic health records are a major source of content for personal health records. We designed and implemented a prototype text translator to make these reports more comprehensible to consumers. The translator identifies difficult terms, replaces them with easier synonyms, and generates and inserts explanatory texts for them. In feasibility testing, the application was used to translate 9 clinical reports. Majority (68.8%) of text replacements and insertions were deemed correct and helpful by expert review. User evaluation demonstrated a non-statistically significant trend toward better comprehension when translation is provided (p=0.15).

Researchers and clinicians are concerned about the impact of electronic health record use and patient-centered communication. Training about patient-centered clinical communication skills with the electronic health record may help clinicians adapt and remain patient-centered. We developed an interactive workshop eliciting challenges and opportunities of working with the electronic health record in clinical practice, introduction of specific patient-centered behaviors and mindful practice techniques, and video demonstrating contrasts in common behavior and "better practices." One hundred thirty-nine resident physicians and faculty supervisors in five residency training programs at the University of Rochester Medical Center participated in the workshops. Participants were asked to complete an 11-item survey of behaviors related to their use of the electronic health record prior to training and after attending training. We used paired t-tests to assess changes in self-reported behavior from pre-intervention to post-intervention. We trained 139 clinicians in the workshops; 110 participants completed the baseline assessment and 39 completed both the baseline and post-intervention assessment. Data from post-curriculum respondents found a statistically significant increase in "I told the patient when turning my attention from the patient to the computer," from 60% of the time prior to the training to 70% of the time after. Data from our program evaluation demonstrated improvement in one communication behavior. Sample size limited the detection of other changes; further research should investigate effective training techniques for patient-centered communication while using the electronic health record. © The Author(s) 2016.

Light-field-driven currents in graphene

The ability to steer electrons using the strong electromagnetic field of light has opened up the possibility of controlling electron dynamics on the sub-femtosecond (less than 10-15 seconds) timescale. In dielectrics and semiconductors, various light-field-driven effects have been explored, including high-harmonic generation, sub-optical-cycle interband population transfer and the non-perturbative change of the transient polarizability. In contrast, much less is known about light-field-driven electron dynamics in narrow-bandgap systems or in conductors, in which screening due to free carriers or light absorption hinders the application of strong optical fields. Graphene is a promising platform with which to achieve light-field-driven control of electrons in a conducting material, because of its broadband and ultrafast optical response, weak screening and high damage threshold. Here we show that a current induced in monolayer graphene by two-cycle laser pulses is sensitive to the electric-field waveform, that is, to the exact shape of the optical carrier field of the pulse, which is controlled by the carrier-envelope phase, with a precision on the attosecond (10-18 seconds) timescale. Such a current, dependent on the carrier-envelope phase, shows a striking reversal of the direction of the current as a function of the driving field amplitude at about two volts per nanometre. This reversal indicates a transition of light-matter interaction from the weak-field (photon-driven) regime to the strong-field (light-field-driven) regime, where the intraband dynamics influence interband transitions. We show that in this strong-field regime the electron dynamics are governed by sub-optical-cycle Landau-Zener-Stückelberg interference, composed of coherent repeated Landau-Zener transitions on the femtosecond timescale. Furthermore, the influence of this sub-optical-cycle interference can be controlled with the laser polarization state. These coherent electron dynamics in
