For doctors returning to work after absence due to ill-health or performance concerns, the obstacles can seem insurmountable. Doctors' perspectives of these obstacles have been investigated. To support them more effectively, the perspectives of organizations that interact with such doctors should also be considered. To explore the obstacles and enablers to doctors' return to work after long-term absence from the perspective of key organizations involved in assessment and support. We identified organizations operating in the field of doctors' health, well-being and performance. We conducted semi-structured, 30-45 min telephone interviews with representatives of the organizations, exploring problems that they had encountered that were experienced by doctors with health or performance concerns returning to work after absence of a month or longer. We analysed our field notes using theoretical analysis. We conducted 11 telephone interviews. Data analysis identified four key themes of obstacles and enablers to returning to work: 'communication', 'return to work', 'finance and funding' and 'relationships and engagement'. Sub-themes relating to the organization and the individual also emerged. Organizations responsible for supporting doctors back to work reported poor communication as a significant obstacle to doctors returning to work after illness. They also reported differences between specialities, employing organizations, occupational health departments and human resources in terms of knowledge and expertise in supporting doctors with complex issues. Clear communication channels, care pathways and support processes, such as workplace advocates, were perceived as strong enablers to return to work for doctors after long-term absence. © The Author 2015.

Patient advocates and safety experts encourage adoption of transparent health records, but sceptics worry that shared notes may offend patients, erode trust or promote defensive medicine. As electronic health records disseminate, such disparate views fuel policy debates about risks and benefits of sharing visit notes with patients through portals. Presurveys and postsurveys from 99 volunteer doctors at three US sites who participated in OpenNotes and postsurveys from 4592 patients who read at least one note and submitted a survey. Patients read notes to be better informed and because they were curious; about a third read them to check accuracy. In total, 7% (331) of patients reported contacting their doctor's office about their note. Of these, 29% perceived an error, and 85% were satisfied with its resolution. Nearly all patients reported feeling better (37%) or the same (62%) about their doctor. Patients who were older (>63), male, non-white, had fair/poor self-reported health or had less formal education were more likely to report feeling better about their doctor. Among doctors, 26% anticipated documentation errors, and 44% thought patients would disagree with notes. After a year, 53% believed patient satisfaction increased, and 51% thought patients trusted them more. None reported ordering more tests or referrals. Despite concerns about errors, offending language or defensive practice, transparent notes overall did not harm the patient-doctor relationship. Rather, doctors and patients perceived relational benefits. Traditionally more vulnerable populations-non-white, those with poorer self-reported health and those with fewer years of formal education-may be particularly likely to feel better about their doctor after reading their notes. Further informing debate about OpenNotes, the findings suggest transparent records may improve patient satisfaction, trust and safety. Published by the BMJ Publishing Group Limited.

Dynamically reconfigurable and transparent signal spectral conversion is expected to play a vital role in seamlessly integrating traditional metropolitan optical networks and mobile fronthaul/backhaul networks. In this paper, a simple digital signal processing (DSP)-enabled spectral converter is proposed and extensively investigated, for the first time, which just utilizes a single standard dual-parallel Mach-Zehnder modulator (DP-MZM) driven by SDN-controllable RF signals and DC bias currents. As an important thrust of the paper, optimum operating conditions of the proposed converter are analytically identified, statistically examined and experimentally verified. Optimum operating condition-supported spectral converter performances in IMDD-based network nodes are explored both theoretically and experimentally in terms of frequency detuning range-dependent conversion efficiency, spectral conversion-induced OSNR/power penalty and transparency to input signal characteristics. The proposed spectral converter has unique advantages including low configuration complexity, strict transparency, SDN-controllable performance reconfigurability and flexibility, as well as negligible spectral conversion-induced latency.
Medical regulation, spectacular transparency and the blame business.
McGivern, Gerry; Fischer, Michael
2010-01-01
The purpose of this paper is to explore general practitioners' (GPs') and psychiatrists' views and experiences of transparent forms of medical regulation in practice, as well as those of medical regulators and those representing patients and professionals. The research included interviews with GPs, psychiatrists and others involved in medical regulation, representing patients and professionals. A qualitative narrative analysis of the interviews was then conducted. Narratives suggest rising levels of complaints, legalisation and blame within the National Health Service (NHS). Three key themes emerge. First, doctors feel "guilty until proven innocent" within increasingly legalised regulatory systems and are consequently practising more defensively. Second, regulation is described as providing "spectacular transparency", driven by political responses to high profile scandals rather than its effects in practice, which can be seen as a social defence. Finally, it is suggested that a "blame business" is driving this form of transparency, in which self-interested regulators, the media, lawyers, and even some patient organisations are fuelling transparency in a wider culture of blame. A relatively small number of people were interviewed, so further research testing the findings would be useful. Transparency has some perverse effects on doctors' practice. Rising levels of blame has perverse consequences for patient care, as doctors are practicing more defensively as a result, as well as significant financial implications for NHS funding. Transparent forms of regulation are assumed to be beneficial and yet little research has examined its effects in practice. In this paper we highlight a number of perverse effects of transparency in practice.
All-dielectric resonant cavity-enabled metals with broadband optical transparency

Metal films with broadband optical transparency are desirable in many optoelectronic devices, such as displays, smart windows, light-emitting diodes and infrared detectors. As bare metal is opaque to light, this issue of transparency attracts great scientific interest. In this work, we proposed and demonstrated a feasible and universal approach for achieving broadband optical transparent (BOT) metals by utilizing all-dielectric resonant cavities. Resonant dielectrics provide optical cavity modes and couple strongly with the surface plasmons of the metal film, and therefore produce a broadband near-unity optical transparent window. The relative enhancement factor (EF) of light transmission exceeds 3400% in comparison with that of pure metal film. Moreover, the transparent metal motif can be realized by other common metals including gold (Au), silver (Ag) and copper (Cu). These optical features together with the fully retained electric and mechanical properties of a natural metal suggest that it will have wide applications in optoelectronic devices.
Enabling and Encouraging Transparency in Earth Science Data for Decision Making
Abbott, S. B.
2010-12-01
Our ability to understand, respond, and make decisions about our changing planet hinges on timely scientific information and situational awareness. Information and understanding will continue to be the foundations of decision support in the face of uncertainty. Over the last 40 years, investments in Earth observations have brought remarkable achievements in weather prediction, disaster prediction and response, land management, and our broad base of Earth science knowledge. The only way to know what is happening to our planet and to manage our resources wisely is to measure it, This means tracking changes decade after decade and reanalyzing the record in light of new insights, technologies, and methodologies. In order to understand and respond to climate change and other global challenges, there is a need for a high degree of transparency in the publication, management, traceability, and citability of science data, and particularly for Earth science data. In addition, it is becoming increasingly important that free, open, and authoritative sources of quality data are available for peer review. One important focus is on applications and opportunities for enhancing data exchange standards for use with Earth science data. By increasing the transparency of scientific work and providing incentives for researchers and institutions to openly share data, we will more effectively leverage the scientific capacity of our Nation to address climate change and to meet future challenges. It is an enormous challenge to collect, organize, and communicate the vast stores of data maintained across the government. The Administration is committed to moving past these barriers in providing the American public with unprecedented access to useful government data, including an open architecture and making data available in multiple formats. The goal is to enable better decision-making, drive transparency, and to help power innovation for a stronger America. Whether for a research project
Reactivity and reactions to regulatory transparency in medicine, psychotherapy and counselling.
McGivern, Gerry; Fischer, Michael D
2012-02-01
We explore how doctors, psychotherapists and counsellors in the U.K. react to regulatory transparency, drawing on qualitative research involving 51 semi-structured interviews conducted during 2008-10. We use the concept of 'reactivity mechanisms' (Espeland & Sauder, 2007) to explain how regulatory transparency disrupts practices through simplifying and decontextualizing them, altering practitioners' reflexivity, leading to defensive forms of practice. We make an empirical contribution by exploring the impact of transparency on doctors compared with psychotherapists and counsellors, who represent an extreme case due to their uniquely complex practice, which is particularly affected by this form of regulation. We make a contribution to knowledge by developing a model of reactivity mechanisms, which explains how clinical professionals make sense of media and professional narratives about regulation in ways that produce emotional reactions and, in turn, defensive reactivity to transparency.

Doctoral aducation is a major priority for European universities. In the context of the Bologna Process the importance of doctoral education as the third cycle of higher education and the first stage of a young researchers career, and thus in linking the European Higher Education and Research Areas, was first highlighted in the 2003 Berlin Report. The core component of doctoral training is the advancement of knowledge through original research. considering the need for structured doctoral programs and the need for transparent supervision and assessment, we note that the normal workload of the third cycle in most countries would correspond 3-4 years full time. This is spirit of the new Spanish Doctoral Law. Then, universities should ensure that their doctoral programmes promote interdisciplinary training and the development of transferable skills, thus meeting the needs of the wider employment market. We need to achieve and overall increase in the numbers of doctoral candidates taking up research careers as early stage researchers and also increase the employability as a normal way as it is the case of other advance countries. In Spain, universities with doctoral nuclear programmes and the CIEMAT, with the sponsorship of the nuclear sector, a doctoral school in nuclear science and engineering should be created to enhance the research careers of Young students for the future of nuclear activities in Spain.

Second-order nonlinearity induced transparency.
Zhou, Y H; Zhang, S S; Shen, H Z; Yi, X X
2017-04-01
In analogy to electromagnetically induced transparency, optomechanically induced transparency was proposed recently in [Science330, 1520 (2010)SCIEAS0036-807510.1126/science.1195596]. In this Letter, we demonstrate another form of induced transparency enabled by second-order nonlinearity. A practical application of the second-order nonlinearity induced transparency is to measure the second-order nonlinear coefficient. Our scheme might find applications in quantum optics and quantum information processing.
Off the Charts: Medical documentation and selective redaction in the age of transparency.
McCarthy, Matthew William; de Asua, Diego Real; Gabbay, Ezra; Fins, Joseph J
2018-01-01
A growing demand for transparency in medicine has the potential to strain the doctor-patient relationship. While information can empower patients, unrestricted patient access to the electronic medical record may have unintended consequences. Medical documentation is often written in language that is inaccessible to people without medical training, and without guidance, patients have no way to interpret the constellation of acronyms, diagnoses, treatments, impressions, and arguments that appear throughout their own chart. Additionally, full transparency may not allow physicians the intellectual or clinical freedom they need to authentically express questions, problematic impressions, and concerns about the patient's clinical and psychosocial issues. This article examines the ethical challenges of transparency in the digital era and suggests that selective redaction may serve as a means to maintain transparency, affirm physician's discretion, and uphold the core values of the doctor-patient relationship amidst disruptive technological change.

Few patients read their doctors' notes, despite having the legal right to do so. As information technology makes medical records more accessible and society calls for greater transparency, patients' interest in reading their doctors' notes may increase. Inviting patients to review these notes could improve understanding of their health, foster productive communication, stimulate shared decision making, and ultimately lead to better outcomes. Yet, easy access to doctors' notes could have negative consequences, such as confusing or worrying patients and complicating rather than improving patient-doctor communication. To gain evidence about the feasibility, benefits, and harms of providing patients ready access to electronic doctors' notes, a team of physicians and nurses have embarked on a demonstration and evaluation of a project called OpenNotes. The authors describe the intervention and share what they learned from conversations with doctors and patients during the planning stages. The team anticipates that "open notes" will spread and suggests that over time, if drafted collaboratively and signed by both doctors and patients, they might evolve to become contracts for care.

Transparency is a key principle in democratic societies. For example, the public sector is in part kept honest and fair with the help of transparency through different freedom of information (FOI) legislations. In the last decades, while FOI legislations have been adopted by more and more countries worldwide, we have entered the information age enabled by the rapid development of information technology. This has led to the need for technological solutions that enhance transparency, for exampl...

Transparent communication after medical error includes disclosing the mistake to the patient, discussing the event with colleagues, and reporting to the institution. Little is known about whether attitudes about these transparency practices are related. Understanding these relationships could inform educational and organizational strategies to promote transparency. We analyzed responses of 3038 US and Canadian physicians to a medical error communication survey. We used bivariate correlations, principal components analysis, and linear regression to determine whether and how physician attitudes about transparent communication with patients, peers, and the institution after error were related. Physician attitudes about disclosing errors to patients, peers, and institutions were correlated (all P's transparent communication with patients and peers/institution included female sex, US (vs Canadian) doctors, academic (vs private) practice, the belief that disclosure decreased likelihood of litigation, and the belief that system changes occur after error reporting. In addition, younger physicians, surgeons, and those with previous experience disclosing a serious error were more likely to agree with disclosure to patients. In comparison, doctors who believed that disclosure would decrease patient trust were less likely to agree with error disclosure to patients. Previous disclosure education was associated with attitudes supporting greater transparency with peers/institution. Physician attitudes about discussing errors with patients, colleagues, and institutions are related. Several predictors of transparency affect all 3 practices and are potentially modifiable by educational and institutional strategies.

Simultaneously achieving high optical transparency and excellent charge mobility in semiconducting polymers has presented a challenge for the application of these materials in future “flexible” and “transparent” electronics (FTEs). Here, by blending only a small amount (∼15 wt %) of a diketopyrrolopyrrole-based semiconducting polymer (DPP2T) into an inert polystyrene (PS) matrix, we introduce a polymer blend system that demonstrates both high field-effect transistor (FET) mobility and excellent optical transparency that approaches 100%. We discover that in a PS matrix, DPP2T forms a web-like, continuously connected nanonetwork that spreads throughout the thin film and provides highly efficient 2D charge pathways through extended intrachain conjugation. The remarkable physical properties achieved using our approach enable us to develop prototype high-performance FTE devices, including colorless all-polymer FET arrays and fully transparent FET-integrated polymer light-emitting diodes.

Understanding doctors' ethical challenges as role virtue conflicts.
McDougall, Rosalind
2013-01-01
This paper argues that doctors' ethical challenges can be usefully conceptualised as role virtue conflicts. The hospital environment requires doctors to be simultaneously good doctors, good team members, good learners and good employees. I articulate a possible set of role virtues for each of these four roles, as a basis for a virtue ethics approach to analysing doctors' ethical challenges. Using one junior doctor's story, I argue that understanding doctors' ethical challenges as role virtue conflicts enables recognition of important moral considerations that are overlooked by other approaches to ethical analysis. © 2011 Blackwell Publishing Ltd.
High Temperature Transparent Furnace Development
Bates, Stephen C.
1997-01-01
This report describes the use of novel techniques for heat containment that could be used to build a high temperature transparent furnace. The primary objective of the work was to experimentally demonstrate transparent furnace operation at 1200 C. Secondary objectives were to understand furnace operation and furnace component specification to enable the design and construction of a low power prototype furnace for delivery to NASA in a follow-up project. The basic approach of the research was to couple high temperature component design with simple concept demonstration experiments that modify a commercially available transparent furnace rated at lower temperature. A detailed energy balance of the operating transparent furnace was performed, calculating heat losses through the furnace components as a result of conduction, radiation, and convection. The transparent furnace shells and furnace components were redesigned to permit furnace operation at at least 1200 C. Techniques were developed that are expected to lead to significantly improved heat containment compared with current transparent furnaces. The design of a thermal profile in a multizone high temperature transparent furnace design was also addressed. Experiments were performed to verify the energy balance analysis, to demonstrate some of the major furnace improvement techniques developed, and to demonstrate the overall feasibility of a high temperature transparent furnace. The important objective of the research was achieved: to demonstrate the feasibility of operating a transparent furnace at 1200 C.
Printable Transparent Conductive Films for Flexible Electronics.
Li, Dongdong; Lai, Wen-Yong; Zhang, Yi-Zhou; Huang, Wei
2018-03-01
Printed electronics are an important enabling technology for the development of low-cost, large-area, and flexible optoelectronic devices. Transparent conductive films (TCFs) made from solution-processable transparent conductive materials, such as metal nanoparticles/nanowires, carbon nanotubes, graphene, and conductive polymers, can simultaneously exhibit high mechanical flexibility, low cost, and better photoelectric properties compared to the commonly used sputtered indium-tin-oxide-based TCFs, and are thus receiving great attention. This Review summarizes recent advances of large-area flexible TCFs enabled by several roll-to-roll-compatible printed techniques including inkjet printing, screen printing, offset printing, and gravure printing using the emerging transparent conductive materials. The preparation of TCFs including ink formulation, substrate treatment, patterning, and postprocessing, and their potential applications in solar cells, organic light-emitting diodes, and touch panels are discussed in detail. The rational combination of a variety of printed techniques with emerging transparent conductive materials is believed to extend the opportunities for the development of printed electronics within the realm of flexible electronics and beyond. © 2018 WILEY-VCH Verlag GmbH & Co.

2016-01-01
On 10 May, over 130 PhD students and their supervisors, from both CERN and partner universities, gathered for the 4th Doctoral Student Assembly in the Council Chamber. The assembly was followed by a poster session, at which eighteen doctoral students presented the outcome of their scientific work. The CERN Doctoral Student Programme currently hosts just over 200 students in applied physics, engineering, computing and science communication/education. The programme has been in place since 1985. It enables students to do their research at CERN for a maximum of three years and to work on a PhD thesis, which they defend at their University. The programme is steered by the TSC committee, which holds two selection committees per year, in June and December. The Doctoral Student Assembly was opened by the Director-General, Fabiola Gianotti, who stressed the importance of the programme in the scientific environment at CERN, emphasising that there is no more rewarding activity than lear...

The development of education options for nurses has been inexorable and it is increasingly the case that senior nurses are considering a doctorate as the logical next step in their educational career. Such individuals need to make important decisions as to whether they should embark on a taught doctorate, professional doctorate or a traditional PhD. Each of these options will necessitate a considerable investment in time and money as well as the sacrifice of quality time and spare time over a significant number of years. A doctorate is not for everyone. Those still reading this text may be asking 'could this possibly be for me'? This paper will try to help the reader decide which if any option to take. It is suggested that nurses will now turn to the doctoral degree as their next adventure in academic study. It is argued that this development is not being controlled by management forces and indeed cannot be controlled by them. This last is chiefly because the move towards doctoral education is led by individuals who choose to study for a doctorate simply because they can. The paper considers what choices are available to nurses who wish to pursue a doctoral programme of study. In particular, this paper considers what new developments in doctoral courses are becoming available and what advantage there may be in studying for one of the newer professional doctorates rather than a traditional PhD. The material here is the result of a review of the literature on recent developments in doctoral education for nurses. The existing provision by UK and other universities was also reviewed, the data being collected by an informal review of universities' advertising material. It is inevitable that some nurses who are already qualified to degree and masters degree will take advantage of the doctoral degree opportunities which now newly present themselves. For nurses in practice, the advantages of the professional doctorate is that it is more structured, enables more peer and

An effective health workforce is essential for achieving health-related new Sustainable Development Goals. Odisha, one of the states in India with low health indicators, faces challenges in recruiting and retaining health staff in the public sector, especially doctors. Recruitment, deployment and career progression play an important role in attracting and retaining doctors. We examined the policies on recruitment, deployment and promotion for doctors in the state and how these policies were perceived to be implemented. We undertook document review and four key informant interviews with senior state-level officials to delineate the policies for recruitment, deployment and promotion. We conducted 90 in-depth interviews, 86 with doctors from six districts and four at the state level to explore the perceptions of doctors about these policies. Despite the efforts by the Government of Odisha through regular recruitments, a quarter of the posts of doctors was vacant across all institutional levels in the state. The majority of doctors interviewed were unaware of existing government rules for placement, transfer and promotion. In addition, there were no explicit rules followed in placement and transfer. More than half (57%) of the doctors interviewed from well-accessible areas had never worked in the identified hard-to-reach areas in spite of having regulatory and incentive mechanisms. The average length of service before the first promotion was 26 (±3.5) years. The doctors expressed satisfaction with the recruitment process. They stated concerns over delayed first promotion, non-transparent deployment policies and ineffective incentive system. Almost all doctors suggested having time-bound and transparent policies. Adequate and appropriate deployment of doctors is a challenge for the government as it has to align the individual aspirations of employees with organizational needs. Explicit rules for human resource management coupled with transparency in implementation can
Methods and apparatus for transparent display using scattering nanoparticles

Transparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light. Exemplary transparent scattering displays can be simple, inexpensive, scalable to large sizes, viewable over wide angular ranges, energy efficient, and transparent simultaneously.

Impact of data transparency: Scientific publications.
Joshi, Mohit; Bhardwaj, Payal
2018-01-01
Data transparency has been an important aspect of medical research as it helps in enabling evidence-based decisions in medicine which leads to foster trust among the patients and research community alike. Currently, it is one of the key talking points owing to a number of initiatives taken by the pharmaceutical organizations, regulatory bodies, and the other decision enablers of the industry. Thanks to this, there are a number of ways by which a single piece of datum is available through multiple access points, namely, clinical trial disclosures (CTDs), clinical study reports (CSRs), plain language summaries, and scientific publications including abstracts, posters, and manuscripts, to name a few. This may pose a burden of documentation on the pharmaceutical organizations, demanding downsizing of medical writing documents. Since CTDs, CSRs, and other regulatory document are more or less template driven; there may not be much scope to interfere with their structure and submission timings. Scientific publications, on the other hand, provide the flexibility of presenting the clinical data that is typically not dependent on a particular format and timelines. The present paper discusses how the upcoming data transparency initiatives could affect the publication practices across the pharmaceutical industry and what could pharmaceutical companies do to get the maximum benefit out of the data transparency initiatives.
Transparency as an element of public confidence

In the modern society, there is increasing demands for greater transparency. It has been discussed with respect to corruption or ethics issues in social science. The need for greater openness and transparency in nuclear regulation is widely recognised as public expectations on regulator grow. It is also related to the digital and information technology that enables disclosures of every activity and information of individual and organisation, characterised by numerous 'small brothers'. Transparency has become a key word in this ubiquitous era. Transparency in regulatory activities needs to be understood in following contexts. First, transparency is one of elements to build public confidence in regulator and eventually to achieve regulatory goal of providing the public with satisfaction at nuclear safety. Transparent bases of competence, independence, ethics and integrity of working process of regulatory body would enhance public confidence. Second, activities transmitting information on nuclear safety and preparedness to be accessed are different types of transparency. Communication is an active method of transparency. With increasing use of web-sites, 'digital transparency' is also discussed as passive one. Transparency in regulatory process may be more important than that of contents. Simply providing more information is of little value and specific information may need to be protected for security reason. Third, transparency should be discussed in international, national and organizational perspectives. It has been demanded through international instruments. for each country, transparency is demanded by residents, public, NGOs, media and other stakeholders. Employees also demand more transparency in operating and regulatory organisations. Whistle-blower may appear unless they are satisfied. Fourth, pursuing transparency may cause undue social cost or adverse effects. Over-transparency may decrease public confidence and the process for transparency may also hinder

Capacitive micro-sensors such as accelerometers, gyroscopes and pressure sensors are increasingly used in the modern electronic world. However, the in vivo use of capacitive sensing for measurement of pressure or other variables inside a human body suffers from significant errors due to stray capacitance. This paper proposes a solution consisting of a transparent thin flexible Faraday cage that surrounds the sensor. By supplying the active sensing voltage simultaneously to the deformable electrode of the capacitive sensor and to the Faraday cage, the stray capacitance during in vivo measurements can be largely eliminated. Due to the transparency of the Faraday cage, the top and bottom portions of a capacitive sensor can be accurately aligned and assembled together. Experimental results presented in the paper show that stray capacitance is reduced by a factor of 10 by the Faraday cage, when the sensor is subjected to a full immersion in water.

Annually about 100,000 acute cardiac deaths occur in Germany. For this reason, there is the obvious need, from a public health perspective, to inform the population about possible measures of their prevention and treatment. Ultimately every patient or admission referring doctor can be thought of as a recipient of "marketing". Other than within the context of economics, in medicine the subject of marketing is likely to produce a negative response. Any doctor engaging in marketing is quickly considered to be engaging in unfair competition at the expense of colleagues ("economic competitors"). However, despite some reservations it would seem sensible to provide transparency concerning the results of treatment. If the manner of competition is the right one, i.e. one that has as its aim to improve patient care, it can at the same time improve such care, motivate doctors and frequently also reduce costs. Transparency of the various aspects of improved medical care in this way represent a "pay-back" to everyone working in the health services. It is desirable to establish an external process of assessing any published data and, as far as possible, exclude all incorrect data from relevant measures of comparison. Competition can then be to the patient's benefit.

Color transparency in semi-inclusive electroproduction of ρ mesons
International Nuclear Information System (INIS)
Frankfurt, L.; Miller, G. A.; Strikman, M.
2008-01-01
We study the electroproduction of ρ mesons in nuclei at intermediate energies, deriving a treatment of the energy lost by the ρ in each step of multiple scattering. This enables a close match between calculations and the experimental kinematic conditions. A standard Glauber calculation is presented, and then the effects of color-transparency are included. The influence of poor experimental resolution on the extracted transparency is assessed. The effects of ρ meson decay inside the nucleus are examined, and are typically about 5% at most. This effect disappears rapidly as Q 2 increases from about 1 to 3 GeV 2 , causing a rise in the transparency that is not attributable to color transparency. The size of color transparency effects for C and Fe nuclei is studied for values of Q 2 up to 10 GeV 2 . The detailed results depend strongly on the assumed value of the ρN cross section. The overall effects of color transparency are greater than about 10% for both nuclear targets if Q 2 is greater than about 5 GeV 2

Doctors with dyslexia: strategies and support.
Locke, Rachel; Alexander, Gail; Mann, Richard; Kibble, Sharon; Scallan, Samantha

Looking beyond dyslexia as an individual doctor's issue requires adjusting a working environment to better serve the needs of doctors with dyslexia. With an increasing number of doctors disclosing dyslexia at medical school, how can educators best provide this support? Our research looks at the impact of dyslexia on clinical practice and the coping strategies used by doctors to minimise the effect. Qualitative data were collected from 14 doctors with dyslexia using semi-structured interviews and by survey. 'In situ' demonstration interviews were conducted in order to understand how dyslexia is managed in the workplace from first-hand experience. Employers and educators who have responsibility for meeting the needs of this group were also consulted. Even in cases of doctors who had a diagnosis, they often did not disclose their dyslexia to their employer. Study participants reported having developed individual ways of coping and devised useful 'workarounds'. Support from employers comes in the form of 'reasonable adjustments', although from our data we cannot be sure that such adjustments contribute to an 'enabling' work environment. Supportive characteristics included the opportunity to shadow others and the time and space to complete paperwork on a busy ward. How can educators best provide support [for doctors with dyslexia]? Doctors with dyslexia need to be helped to feel comfortable enough to disclose. Educators need to challenge any negative assumptions that exist as well as promote understanding about the elements that contribute to a positive working environment. As a result of the research there is now practice available for educators to identify evidence-based strategies and resources. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

After bills to launch the Social Security and Tax Number System were enacted in 2013, health and political officials have considered the Healthcare Number System (the System). However, little is known about doctors' awareness and concerns about the System. This study aimed to measure how many doctors disagree with the System, examine the doctors' characteristics, and analyze the benefits and harms of the System that they identified. A cross-sectional survey was conducted of doctors via the Internet. The participants were selected from a convenience sample of a panel of doctors based on stratified sampling including four groups: working at a hospital and content analysis. There were 562 respondents (68%). By group, 16/143 (11%), 25/138 (18%), 31/132 (23%), and 43/149 (29%) doctors, respectively, thought that the System was unnecessary. The variables that correlated with the main outcome were age (per 5 years; odds ratio [95% confidence interval], 1.14 [1.01-1.29]) and type of medical facility (working at a clinic; 1.99 [1.30-3.08]). The doctors identified that unifying information could decrease administrative duties, facilitate inter-facility collaboration, and prevent inappropriate medical consultations. This could result in decreased healthcare costs and personalized healthcare. However, the doctors also identified that integrating information and dealing with big data could increase information leakage and information management, cause over-monitoring of doctors, and enable the inappropriate use of integrated information. This could result in deteriorating healthcare. Since some information should not be integrated, the System raises ethical considerations about privacy. Among the doctors surveyed here, 10-30% thought the System was unnecessary. These respondents tended to be older and work at a clinic. The System could decrease the cost of healthcare and enable personalized healthcare but could also increase information leakage and information management, cause

Full Text Available Certificate transparency (CT is an elegant mechanism designed to detect when a certificate authority (CA has issued a certificate incorrectly. Many CAs now support CT and it is being actively deployed in browsers. However, a number of privacy-related challenges remain. In this paper we propose practical solutions to two issues. First, we develop a mechanism that enables web browsers to audit a CT log without violating user privacy. Second, we extend CT to support non-public subdomains.
What parents want from doctors in end-of-life decision-making for children.
Sullivan, J; Monagle, P; Gillam, L
2014-03-01
End-of-life decision-making is difficult for everyone involved, as many studies have shown. Within this complexity, there has been little information on how parents see the role of doctors in end-of-life decision-making for children. This study aimed to examine parents' views and experiences of end-of-life decision-making. A qualitative method with a semistructured interview design was used. Parent participants were living in the community. Twenty-five bereaved parents. Parents reported varying roles taken by doctors: being the provider of information without opinion; giving information and advice as to the decision that should be taken; and seemingly being the decision maker for the child. The majority of parents found their child's doctor enabled them to be the ultimate decision maker for their child, which was what they very clearly wanted to be, and consequently enabled them to exercise their parental autonomy. Parents found it problematic when doctors took over decision-making. A less frequently reported, yet significant role for doctors was to affirm decisions after they had been made by parents. Other important aspects of the doctor's role were to provide follow-up support and referral. Understanding the role that doctors take in end-of-life decisions, and the subsequent impact of that role from the perspective of parents can form the basis of better informed clinical practice.
Lattice Transparency of Graphene.

2017-03-08
Here, we demonstrated the transparency of graphene to the atomic arrangement of a substrate surface, i.e., the "lattice transparency" of graphene, by using hydrothermally grown ZnO nanorods as a model system. The growth behaviors of ZnO nanocrystals on graphene-coated and uncoated substrates with various crystal structures were investigated. The atomic arrangements of the nucleating ZnO nanocrystals exhibited a close match with those of the respective substrates despite the substrates being bound to the other side of the graphene. By using first-principles calculations based on density functional theory, we confirmed the energetic favorability of the nucleating phase following the atomic arrangement of the substrate even with the graphene layer present in between. In addition to transmitting information about the atomic lattice of the substrate, graphene also protected its surface. This dual role enabled the hydrothermal growth of ZnO nanorods on a Cu substrate, which otherwise dissolved in the reaction conditions when graphene was absent.

Full Text Available In this article, we explore the learning experiences of doctoral candidates as they use qualitative data analysis software (QDAS. Of particular interest is the process of adopting technology during the development of research methodology. Using an action research approach, data was gathered over five years from advanced doctoral research candidates and supervisors. The technology acceptance model (TAM was then applied as a theoretical analytic lens for better understanding how students interact with new technology. Findings relate to two significant barriers which doctoral students confront: 1. aligning perceptions of ease of use and usefulness is essential in overcoming resistance to technological change; 2. transparency into the research process through technology promotes insights into methodological challenges. Transitioning through both barriers requires a competent foundation in qualitative research. The study acknowledges the importance of higher degree research, curriculum reform and doctoral supervision in post-graduate research training together with their interconnected relationships in support of high-quality inquiry.

The color transparency of pions in various nuclei has been measured and compared with the proton transparency. The measurement results are consistent with semi-classical predictions that the pion transparency is larger than the proton transparency at the same incident momentum and their ratio becomes larger as the nucleus becomes heavier. The energy dependence of the transparency has been studied based on the semi-classical theory and the result shows that the transparency can be written into two factors. The physics interpretations of the two factors have been discussed. A new experimental apparatus, the Exclusive Variable Apparatus (EVA) at Brookhaven National Laboratory, along with unique electronic techniques chosen for enabling the EVA trigger system to fulfill physics requirements of the experiment, have been described

Transparency of Magnetized Plasma at Cyclotron Frequency
International Nuclear Information System (INIS)
G. Shvets; J.S. Wurtele
2002-03-01
Electromagnetic radiation is strongly absorbed by a magnetized plasma if the radiation frequency equals the cyclotron frequency of plasma electrons. It is demonstrated that absorption can be completely canceled in the presence of a magnetostatic field of an undulator or a second radiation beam, resulting in plasma transparency at the cyclotron frequency. This effect is reminiscent of the electromagnetically induced transparency (EIT) of the three-level atomic systems, except that it occurs in a completely classical plasma. Unlike the atomic systems, where all the excited levels required for EIT exist in each atom, this classical EIT requires the excitation of the nonlocal plasma oscillation. The complexity of the plasma system results in an index of refraction at the cyclotron frequency that differs from unity. Lagrangian description was used to elucidate the physics and enable numerical simulation of the plasma transparency and control of group and phase velocity. This control naturally leads to applications for electromagnetic pulse compression in the plasma and electron/ion acceleration

Results: Partial results show convergence of disclosure and transparency principles. Conclusions: Indicate that public institutions should worry about performing the practices of good governance as a way to mitigate the informational asymmetry.
Utilisation of transparent synthetic soil surrogates in geotechnical physical models: A review
Directory of Open Access Journals (Sweden)

2016-08-01
Full Text Available Efforts to obtain non-intrusive measurement of deformations and spatial flow within soil mass prior to the advent of transparent soils have perceptible limitations. The transparent soil is a two-phase medium composed of both the synthetic aggregate and fluid components of identical refractive indices aiming at attaining transparency of the resulting soil. The transparency facilitates real life visualisation of soil continuum in physical models. When applied in conjunction with advanced photogrammetry and image processing techniques, transparent soils enable the quantification of the spatial deformation, displacement and multi-phase flow in physical model tests. Transparent synthetic soils have been successfully employed in geotechnical model tests as soil surrogates based on the testing results of their geotechnical properties which replicate those of natural soils. This paper presents a review on transparent synthetic soils and their numerous applications in geotechnical physical models. The properties of the aggregate materials are outlined and the features of the various transparent clays and sands available in the literature are described. The merits of transparent soil are highlighted and the need to amplify its application in geotechnical physical model researches is emphasised. This paper will serve as a concise compendium on the subject of transparent soils for future researchers in this field.
The health care value transparency movement and its implications for radiology.
Durand, Daniel J; Narayan, Anand K; Rybicki, Frank J; Burleson, Judy; Nagy, Paul; McGinty, Geraldine; Duszak, Richard
2015-01-01
The US health care system is in the midst of disruptive changes intended to expand access, improve outcomes, and lower costs. As part of this movement, a growing number of stakeholders have advocated dramatically increasing consumer transparency into the quality and price of health care services. The authors review the general movement toward American health care value transparency within the public, private, and nonprofit sectors, with an emphasis on those initiatives most relevant to radiology. They conclude that radiology, along with other "ancillary services," has been a major focus of early efforts to enhance consumer price transparency. By contrast, radiology as a field remains in the "middle of the pack" with regard to quality transparency. There is thus the danger that radiology value transparency in its current form will stimulate primarily price-based competition, erode provider profit margins, and disincentivize quality. The authors conclude with suggested actions radiologists can take to ensure that a more optimal balance is struck between quality transparency and price transparency, one that will enable true value-based competition among radiologists rather than commoditization.

Suicide in doctors and wives of doctors.
Sakinofsky, I
1980-06-01
This paper re-examines the widespread belief that doctors have a proneness for suicide greater than the general population. The Standardized Mortality Ratio for male physicians is 335 and for single women doctors 257. Doctors' wives have an even greater risk: their SMR is 458. These rates for doctors are higher than for most other professional groups (except pharmacists) and the rate for doctors' wives far exceeds that for wives of other professionals. The intrinsic causes of the physician's high occupational mortality include his knowledge of toxicology and ready access to lethal drugs, so that impulsive suicide is more often successful. Professional stress and overwork, particularly the unrelenting responsibility for decisions upon which the lives of others may depend, have been inculpated. These stresses interact with the decline in the doctors' self-respect and with a personality that is prestige-oriented and independent. Some physicians turn in their frustration to alcohol/and or drugs, accelerating the process of deterioration. The high suicide rate in doctors' wives appears to be the result of unrequited needs for caring and dependency which the doctors' career demands and personality deny them.

We report highly transparent polymer solar cells using metallic silver nanowires (AgNWs) as both the electron- and hole-collecting electrodes. The entire stack of the devices is processed from solution using a doctor blading technique. A thin layer of zinc oxide nanoparticles is introduced between photoactive layer and top AgNW electrode which plays decisive roles in device functionality: it serves as a mechanical foundation which allows the solution-deposition of top AgNWs, and more importantly it facilitates charge carriers extraction due to the better energy level alignment and the formation of ohmic contacts between the active layer/ZnO and ZnO/AgNWs. The resulting semitransparent polymer:fullerene solar cells showed a power conversion efficiency of 2.9%, which is 72% of the efficiency of an opaque reference device. Moreover, an average transmittance of 41% in the wavelength range of 400-800 nm is achieved, which is of particular interest for applications in transparent architectures.

Mortality and morbidity data suggest that men have shorter life expectancies than women and outrank women on several leading causes of death. These gendered disparities may be influenced by psychosocial factors like masculinity. Three studies (Total N=546) examined the role of masculinity in men's doctor choices and doctor-patient interactions. In Studies 1 and 2, men completed measures of masculinity, gender bias, and doctor preference. Using structural equation modeling, we tested the direct relationship between masculinity and male doctor preference and the indirect relationship of masculinity on male doctor preference through an association with gendered competence stereotypes. Participants in Study 3 disclosed symptoms in private followed by disclosure to a male or female interviewer in a clinical setting. Using repeated measures analysis of variance (ANOVA), we examined the interaction among symptom reporting, masculinity and doctor gender, controlling for participant comfort. In Study 1, results suggested that masculinity encouraged choice of a male doctor directly and indirectly via beliefs that men make more competent doctors than women; Study 2 directly replicated the results of Study 1. In Study 3, independent of participant comfort, an interaction between interviewer gender and masculinity emerged such that men scoring higher on masculinity reported symptoms less consistently to male interviewers (relative to higher scoring men reporting to female interviewers); the reverse was found for men scoring low on masculinity. Taken together these studies suggest that masculinity may affect men's health by encouraging choice of a male doctor with whom doctor-patient communication may be impaired.

The Doctoral Schools at Ghent University have a three-fold mission: (1) to provide support to doctoral students during their doctoral research, (2) to foster a quality culture in (doctoral) research, (3) to promote the international and social stature and prestige of the doctorate vis-a-vis potential researchers and the potential labour market. The Doctoral Schools offer top-level specialized courses and transferable skills training to doctoral students as part of their doctoral training programme. They establish mechanisms of quality assurance in doctoral research. The Doctoral Schools initialize and support initiatives of internationalization. They also organize information sessions, promotional events and interaction with the labour market, and as such keep a finger on the pulse of external stakeholders.

Although high-resolution three-dimensional imaging of endoscopically resected gastrointestinal specimens can help elucidating morphological features of gastrointestinal mucosa or tumor, there are no established methods to achieve this without breaking specimens apart. We evaluated the utility of transparency-enhancing technology for three-dimensional assessment of gastrointestinal mucosa in porcine models. Esophagus, stomach, and colon mucosa samples obtained from a sacrificed swine were formalin-fixed and paraffin-embedded, and subsequently deparaffinized for analysis. The samples were fluorescently stained, optically cleared using transparency-enhancing technology: ilLUmination of Cleared organs to IDentify target molecules method (LUCID), and visualized using laser scanning microscopy. After observation, all specimens were paraffin-embedded again and evaluated by conventional histopathological assessment to measure the impact of transparency-enhancing procedures. As a result, microscopic observation revealed horizontal section views of mucosa at deeper levels and enabled the three-dimensional image reconstruction of glandular and vascular structures. Besides, paraffin-embedded specimens after transparency-enhancing procedures were all assessed appropriately by conventional histopathological staining. These results suggest that transparency-enhancing technology may be feasible for clinical application and enable the three-dimensional structural analysis of endoscopic resected specimen non-destructively. Although there remain many limitations or problems to be solved, this promising technology might represent a novel histopathological method for evaluating gastrointestinal cancers. © 2018 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.
Concealed, Unobtrusive Ear-Centered EEG Acquisition: cEEGrids for Transparent EEG
Bleichner, Martin G.; Debener, Stefan
2017-01-01
Electroencephalography (EEG) is an important clinical tool and frequently used to study the brain-behavior relationship in humans noninvasively. Traditionally, EEG signals are recorded by positioning electrodes on the scalp and keeping them in place with glue, rubber bands, or elastic caps. This setup provides good coverage of the head, but is impractical for EEG acquisition in natural daily-life situations. Here, we propose the transparent EEG concept. Transparent EEG aims for motion tolerant, highly portable, unobtrusive, and near invisible data acquisition with minimum disturbance of a user's daily activities. In recent years several ear-centered EEG solutions that are compatible with the transparent EEG concept have been presented. We discuss work showing that miniature electrodes placed in and around the human ear are a feasible solution, as they are sensitive enough to pick up electrical signals stemming from various brain and non-brain sources. We also describe the cEEGrid flex-printed sensor array, which enables unobtrusive multi-channel EEG acquisition from around the ear. In a number of validation studies we found that the cEEGrid enables the recording of meaningful continuous EEG, event-related potentials and neural oscillations. Here, we explain the rationale underlying the cEEGrid ear-EEG solution, present possible use cases and identify open issues that need to be solved on the way toward transparent EEG. PMID:28439233
A Framework for Security Transparency in Cloud Computing

Full Text Available Individuals and corporate users are persistently considering cloud adoption due to its significant benefits compared to traditional computing environments. The data and applications in the cloud are stored in an environment that is separated, managed and maintained externally to the organisation. Therefore, it is essential for cloud providers to demonstrate and implement adequate security practices to protect the data and processes put under their stewardship. Security transparency in the cloud is likely to become the core theme that underpins the systematic disclosure of security designs and practices that enhance customer confidence in using cloud service and deployment models. In this paper, we present a framework that enables a detailed analysis of security transparency for cloud based systems. In particular, we consider security transparency from three different levels of abstraction, i.e., conceptual, organisation and technical levels, and identify the relevant concepts within these levels. This allows us to provide an elaboration of the essential concepts at the core of transparency and analyse the means for implementing them from a technical perspective. Finally, an example from a real world migration context is given to provide a solid discussion on the applicability of the proposed framework.

Toward transparent and self-activated graphene harmonic transponder sensors
Huang, Haiyu Harry; Sakhdari, Maryam; Hajizadegan, Mehdi; Shahini, Ali; Akinwande, Deji; Chen, Pai-Yen

We propose the concept and design of a transparent, flexible, and self-powered wireless sensor comprising a graphene-based sensor/frequency-modulator circuitry and a graphene antenna. In this all-graphene device, the multilayered-graphene antenna receives the fundamental tone at C band and retransmits the frequency-modulated sensed signal (harmonic tone) at X band. The frequency orthogonality between the received/re-transmitted signals may enable high-performance sensing in severe interference/clutter background. Here, a fully passive, quad-ring frequency multiplier is proposed using graphene field-effect transistors, of which the unique ambipolar charge transports render a frequency doubling effect with conversion gain being chemically sensitive to exposed gas/molecular/chemical/infectious agents. This transparent, light-weight, and self-powered system may potentially benefit a number of wireless sensing and diagnosis applications, particularly for smart contact lenses/glasses and microscope slides that require high optical transparency.

To examine doctors' experiences of complaints, including which aspects are most stressful. We also investigated how doctors felt complaints processes could be improved. A qualitative study based on a cross-sectional survey of members of the British Medical Association (BMA). We asked the following: (1) Try to summarise as best as you can your experience of the complaints process and how it made you feel. (2) What were the most stressful aspects of the complaint? (3) What would you improve in the complaints system? We sent the survey to 95 636 doctors, and received 10 930 (11.4%) responses. Of these, 6146 had a previous, recent or current complaint and 3417 (31.3%) of these respondents answered questions 1 and 2. We randomly selected 1000 answers for analysis, and included 100 using the saturation principle. Of this cohort, 93 responses for question 3 were available. Doctors frequently reported feeling powerless, emotionally distressed, and experiencing negative feelings towards both those managing complaints and the complainants themselves. Many felt unsupported, fearful of the consequences and that the complaint was unfair. The most stressful aspects were the prolonged duration and unpredictability of procedures, managerial incompetence, poor communication and perceiving that processes are biased in favour of complainants. Many reported practising defensively or considering changing career after a complaint, and few found any positive outcomes from complaints investigations. Physicians suggested procedures should be more transparent, competently managed, time limited, and that there should be an open dialogue with complainants and policies for dealing with vexatious complaints. Some felt more support for doctors was needed. Complaints seriously impact on doctors' psychological wellbeing, and are associated with defensive practise. This is not beneficial to patient care. To improve procedures, doctors propose they are simplified, time limited and more
Consideration Sets and Their Role in Modelling Doctor Recommendations About Contraceptives.
Fiebig, Denzil G; Viney, Rosalie; Knox, Stephanie; Haas, Marion; Street, Deborah J; Hole, Arne R; Weisberg, Edith; Bateson, Deborah
2017-01-01
Decisions about prescribed contraception are typically the result of a consultation between a woman and her doctor. In order to better understand contraceptive choice within this environment, stated preference methods are utilized to ask doctors about what contraceptive options they would discuss with different types of women. The role of doctors is to confine their discussion to a subset of products that best match their patient. This subset of options forms the consideration set from which the ultimate recommendation is made. Given the existence of consideration sets we address the issue of how to model appropriately the ultimate recommendations. The estimated models enable us to characterize doctor recommendations and how they vary with patient attributes and to highlight where recommendations are clear and when they are uncertain. The results also indicate systematic variation in recommendations across different types of doctors, and in particular we observe that some doctors are reluctant to embrace new products and instead recommend those that are more familiar. Such effects are one possible explanation for the relatively low uptake of more cost effective longer acting reversible contraceptives and indicate that further education and training of doctors may be warranted.

Transparent conductive adhesives (TCAs) can enable conductivity between two substrates, which is useful for a wide range of electronic devices. Here, we have developed a TCA composed of a polymer-particle blend with ethylene-vinyl acetate as the transparent adhesive and metal-coated flexible poly(methyl methacrylate) microspheres as the conductive particles that can provide conductivity and adhesion regardless of the surface texture. This TCA layer was designed to be nearly transparent, conductive in only the out-of-plane direction, and of practical adhesive strength to hold the substrates together. The series resistance was measured at 0.3 and 0.8 O cm2 for 8 and 0.2% particle coverage, respectively, while remaining over 92% was transparent in both cases. For applications in photovoltaic devices, such as mechanically stacked multijunction III-V/Si cells, a TCA with 1% particle coverage will have less than 0.5% power loss due to the resistance and less than 1% shading loss to the bottom cell.
Transparent conducting oxide top contacts for organic electronics
Franklin, Joseph B.
2014-01-01
A versatile method for the deposition of transparent conducting oxide (TCO) layers directly onto conjugated polymer thin film substrates is presented. Using pulsed laser deposition (PLD) we identify a narrow window of growth conditions that permit the deposition of highly transparent, low sheet resistance aluminium-doped zinc oxide (AZO) without degradation of the polymer film. Deposition on conjugated polymers mandates the use of low growth temperatures (<200°C), here we deposit AZO onto poly-3-hexylthiophene (P3HT) thin films at 150°C, and investigate the microstructural and electrical properties of the AZO as the oxygen pressure in the PLD chamber is varied (5-75 mTorr). The low oxygen pressure conditions previously optimized for AZO deposition on rigid substrates are shown to be unsuitable, resulting in catastrophic damage of the polymer films. By increasing the oxygen pressure, thus reducing the energy of the ablated species, we identify conditions that allow direct deposition of continuous, transparent AZO films without P3HT degradation. We find that uptake of oxygen into the AZO films reduces the intrinsic charge carriers and AZO films with a measured sheet resistance of approximately 500 Ω □-1 can be prepared. To significantly reduce this value we identify a novel process in which AZO is deposited over a range of oxygen pressures-enabling the deposition of highly transparent AZO with sheet resistances below 50 Ω □-1 directly onto P3HT. We propose these low resistivity films are widely applicable as transparent top-contacts in a range of optoelectronic devices and highlight this by demonstrating the operation of a semi-transparent photovoltaic device. © 2014 The Royal Society of Chemistry. 2014.
Doctors on display: the evolution of television's doctors.
Tapper, Elliot B
2010-10-01
Doctors have been portrayed on television for over 50 years. In that time, their character has undergone significant changes, evolving from caring but infallible supermen with smoldering good looks and impeccable bedside manners to drug-addicted, sex-obsessed antiheroes. This article summarizes the major programs of the genre and explains the pattern of the TV doctors' character changes. Articulated over time in the many permutations of the doctor character is a complex, constant conversation between viewer and viewed representing public attitudes towards doctors, medicine, and science.

[Influence of patients' attitude on doctors' satisfaction with the doctor-patient relationship].
Xie, Zheng; Qiu, Ze-qi; Zhang, Tuo-hong
2009-04-18
To describe the doctors' satisfaction of the doctor-patient relationship and find out the influencing factors of the patients, gathering evidence to improve the doctor-patient relationship. This study was a cross-sectional study, in which doctors and nurses in 10 hospitals of Beijing, Shandong and Chongqing were surveyed with structured questionnaires and in-depth interviews. The mean score of the doctors' satisfaction of the doctor-patient relationship was 59.97, which was much lower than the patients'. The patients' socio-demographic characteristics, social economic status (SES) and behavior characteristics influence the interaction of the doctors and the patients. The doctors' satisfaction of the doctor-patient relationship was influenced by the patients' trust. The doctors' perspective is helpful to define the tension and the cause of the doctor-patient relationship. The patients' characteristics have important influence on the doctor-patient relationship. It's necessary to take action on the patients to improve the doctor-patient relationship.

A material architecture and laser-based microfabrication technique is introduced to produce electrically conductive films (sheet resistance = 2.95 Ω sq -1 ; resistivity = 1.77 × 10 -6 Ω m) that are soft, elastic (strain limit >100%), and optically transparent. The films are composed of a grid-like array of visually imperceptible liquid-metal (LM) lines on a clear elastomer. Unlike previous efforts in transparent LM circuitry, the current approach enables fully imperceptible electronics that have not only high optical transmittance (>85% at 550 nm) but are also invisible under typical lighting conditions and reading distances. This unique combination of properties is enabled with a laser writing technique that results in LM grid patterns with a line width and pitch as small as 4.5 and 100 µm, respectively-yielding grid-like wiring that has adequate conductivity for digital functionality but is also well below the threshold for visual perception. The electrical, mechanical, electromechanical, and optomechanical properties of the films are characterized and it is found that high conductivity and transparency are preserved at tensile strains of ≈100%. To demonstrate their effectiveness for emerging applications in transparent displays and sensing electronics, the material architecture is incorporated into a couple of illustrative use cases related to chemical hazard warning. © 2018 WILEY-VCH Verlag GmbH & Co.

Patient-doctor relationship: the practice orientation of doctors in Kano.
Abiola, T; Udofia, O; Abdullahi, A T
2014-01-01
Attitude and orientation of doctors to the doctor-patient relationship has a direct influence on delivery of high quality health- care. No study to the knowledge of these researchers has so far examined the practice orientation of doctors in Nigeria to this phenomenon. The aims of this study were to determine the orientation of Kano doctors to the practice of doctor-patient relationship and physicians' related-factors. Participants were doctors working in four major hospitals (i.e., two federal-owned and two state-owned) servicing Kano State and its environs. The Patient-Practitioner Orientation Scale (PPOS) and a socio-demographic questionnaire were completed by the 214 participants. The PPOS has 18 items and measures three parameters of a total score and two dimension of "sharing" and "caring". The mean age of participants was 31.72 years (standard deviation = 0.87), with 22% being females, 40.7% have been practicing for ≥ 6 years and about two-third working in federal-owned health institution. The Cronbach's alpha of total PPOS scores was 0.733 and that of two sub-scale scores of "sharing" and "caring" were 0.659 and 0.546 respectively. Most of the doctors' orientation (92.5%) was towards doctor-centered (i.e., paternalistic) care, majority (75.2%) upheld the view of not sharing much information and control with patients, and showing little interest in psychosocial concerns of patients (i.e., 'caring'=93.0%). Respondents' characteristics that were significantly associated with high doctor 'caring' relationship orientation were being ≥ 30-year-old and practicing for ≥ 6 years. Working in State-owned hospitals was also significantly associated with high doctor "sharing" orientation. This paper demonstrated why patient-centered medical interviewing should be given top priority in medical training in Nigeria, and particularly for federal health institutions saddled with production of new doctors and further training for practicing doctors.
Transparency and the Paris Agreement: driving ambitious action in the new climate regime

By collecting, processing, and sharing information on country and collective mitigation implementation, a well-constructed transparency system is a key enabler for building trust in collective action among countries. In this way, it plays a critical role in allaying concerns countries may have on lack of collective action, concerns which currently limit their mitigation ambition. An indispensable role for the legal Paris Agreement is to institute processes such as the transparency system that help raise over time countries' ambition to an adequate level. This will be especially important if the Intended Nationally Determined Contributions (INDCs) countries submit this year in aggregate fall short of immediately placing the world on 2 degrees emissions pathway. This paper identifies four essential principles that would enable the transparency system to build trust in collective action. Together, universality and self-differentiation set the basis for constructing a system in which all countries report on information, drawing from a menu of reporting options that allows them to do so in a way aligned with their Nationally Determined Contributions (NDCs) and national capacities. No-backsliding helps guard against any lessening of ambition with respect to the current reporting and review requirements. In turn, continuous improvement helps ensure that ambition in the system rises over time. The biennial reporting and review processes established under the Cancun Agreements can serve as a solid basis. This paper analyses these processes' strengths and weaknesses, and proposes concrete modifications to align the transparency system with the above four principles. The paper notably advances a detailed proposal for how to bring about the necessary modification of merging the developed country and developing country reporting tracks and review tracks that make up the current transparency system. The paper also introduces several additions to the new transparency

Metamaterials have recently enabled coupling induced transparency due to interference effects in coupled subwavelength resonators. In this work, we present a three dimensional (3-D) metamaterial design with six-fold rotational symmetry that shows electromagnetically induced transparency with a strong polarization dependence to the incident electromagnetic wave due to the ultra-sharp resonance line width as a result of interaction between the constituent meta-atoms. However, when the six-fold rotationally symmetric unit cell design was re-arranged into a fourfold rotational symmetry, we observed the excitation of a polarization insensitive dual-band transparency. Thus, the 3-D split-ring resonators allow new schemes to observe single and multi-band classical analogues of electromagnetically induced transparencies that has huge potential applications in slowing down light, sensing modalities, and filtering functionalities either in the passive mode or the active mode where such effects could be tuned by integrating materials with dynamic properties.

The doctor(s) in house: an analysis of the evolution of the television doctor-hero.
Strauman, Elena C; Goodier, Bethany C
2011-03-01
The medical drama and its central character, the doctor-hero have been a mainstay of popular television. House M.D. offers a new (and problematic) iteration of the doctor-hero. House eschews the generic conventions of the "television doctor" by being neither the idealized television doctor of the past, nor the more recent competent but often fallible physicians in entertainment texts. Instead, his character is a fragmented text which privileges the biomedical over the personal or emotional with the ultimate goal of scientifically uncovering and resolving instances of disease. This article examines the implicit and explicit messages in House M.D. and critically analyzes both the show and its lead character in relation to the traditional medical drama genre that highlights the "doctor-hero" as the central character. While at first House seems to completely violate narrative and generic norms, ultimately the program provides a new form that reinforces the presence of the doctor-hero, but highlights House's character as the central figure who is personally and interpersonally problematic but biomedically effective.
High aspect ratio silver grid transparent electrodes using UV embossing process
Directory of Open Access Journals (Sweden)
Dong Jin Kim
2017-10-01
Full Text Available This study presents a UV embossing process to fabricate high aspect ratio silver grid transparent electrodes on a polymer film. Transparent electrodes with a high optical transmittance (93 % and low sheet resistance (4.6 Ω/sq were fabricated without any high temperature or vacuum processes. The strong adhesion force between the UV resin and the silver ink enables the fabrication of silver microstructures with an aspect ratio higher than 3. The high aspect ratio results in a low sheet resistance while maintaining a high optical transmittance. Multi-layer transparent electrodes were fabricated by repeating the proposed UV process. Additionally, a large-area of 8-inch touch panel was fabricated with the proposed UV process. The proposed UV process is a relatively simple and low cost process making it suitable for large-area production as well as mass production.

2013-04-16
Todays solar cells are fabricated using metal oxide based transparent conductive coatings (TCC) or metal wires with optoelectronic performance exceeding that currently possible with Carbon Nanotube (CNT) based TCCs. The motivation for replacing current TCC is their inherent brittleness, high deposition cost, and high deposition temperatures; leading to reduced performance on thin substrates. With improved processing, application and characterization techniques Nanofiber and/or CNT based TCCs can overcome these shortcomings while offering the ability to be applied in atmospheric conditions using low cost coating processes At todays level of development, CNT based TCC are nearing commercial use in touch screens, some types of information displays (i.e. electronic paper), and certain military applications. However, the resistivity and transparency requirements for use in current commercial solar cells are more stringent than in many of these applications. Therefore, significant research on fundamental nanotube composition, dispersion and deposition are required to reach the required performance commanded by photovoltaic devices. The objective of this project was to research and develop transparent conductive coatings based on novel nanomaterial composite coatings, which comprise nanotubes, nanofibers, and other nanostructured materials along with binder materials. One objective was to show that these new nanomaterials perform at an electrical resistivity and optical transparency suitable for use in solar cells and other energy-related applications. A second objective was to generate new structures and chemistries with improved resistivity and transparency performance. The materials also included the binders and surface treatments that facilitate the utility of the electrically conductive portion of these composites in solar photovoltaic devices. Performance enhancement venues included: CNT purification and metallic tube separation techniques, chemical doping, CNT

Transparent lithium-ion batteries
Yang, Y.
2011-07-25
Transparent devices have recently attracted substantial attention. Various applications have been demonstrated, including displays, touch screens, and solar cells; however, transparent batteries, a key component in fully integrated transparent devices, have not yet been reported. As battery electrode materials are not transparent and have to be thick enough to store energy, the traditional approach of using thin films for transparent devices is not suitable. Here we demonstrate a grid-structured electrode to solve this dilemma, which is fabricated by a microfluidics-assisted method. The feature dimension in the electrode is below the resolution limit of human eyes, and, thus, the electrode appears transparent. Moreover, by aligning multiple electrodes together, the amount of energy stored increases readily without sacrificing the transparency. This results in a battery with energy density of 10 Wh/L at a transparency of 60%. The device is also flexible, further broadening their potential applications. The transparent device configuration also allows in situ Raman study of fundamental electrochemical reactions in batteries.

Intra-oral electron therapy for carcinoma of the oral cavity is a well-established treatment modality. However, the conventional metallic tubes were inconvenient to use because the irradiation field had to be confirmed by a side mirror. We devised transparent acrylic tubes which enable the positioning easy by confirming the tumor and irradiation field directry. Seven cases of various intra-oral carcinomas were treated with these new transparent acrylic tubes and good results were obtained. (author)

Highlights: > Transparent TiO{sub 2} films were prepared by the atomized spray pyrolysis method. > These films contain 3-5 nm discrete particles, interconnected to give a crack-free thin film structure. > Dye-absorption of the TiO{sub 2} film is 2.16 times higher than those used in conventional DSCs. > Conversion efficiency of 8.2% can be achieved with 1000 W m{sup -2} irradiation. - Abstract: Preparation of crack-free thin films of interconnected and non-agglomerated TiO{sub 2} nanoparticles on electronically conducting fluorine doped tin oxide surfaces is instrumental in designing and developing transparent dye-sensitized solar cells (DSCs). A novel technique called 'Atomized Spray Pyrolysis' (ASP) has been designed and developed to achieve such perfectly transparent thin films. Optical transmittance of TiO{sub 2} films produced on FTO surface by this ASP method has been compared with those obtained by doctor-blading and by hand spray methods and found that the atomized spray pyrolysis technique give films with high transparency. Dye adsorption per gram of TiO{sub 2} is 2.16 times higher in the sample produced by the ASP method when compared to the film produced by the hand spray method and is 1.60 times higher than that produced by the doctor-blading method using a commercially available TiO{sub 2} nanocrystalline paste. SEM studies show the presence of interconnected discrete particles in the film produced by the ASP method. The fill factor (ff) remains almost constant for the cells with thickness from 6 {mu}m to 13 {mu}m but the highest photovoltage and photocurrent were found in {approx}10 {mu}m film based DSC which gave 8.2% conversion efficiency at AM 1.5 irradiation for cells of 0.25 cm{sup 2} active area.

Introduction: Radiography aspires to be a research active profession, but there is limited information regarding the number of individuals with, or studying for, a doctoral award. This study aims to profile UK doctoral radiographers; including their chosen award, approach and employment status. Method: This was a prospective cohort study utilising an electronic survey. No formal database of doctoral radiographers existed therefore a snowball sampling method was adopted. The study sample was radiographers (diagnostic and therapeutic) based in the UK who were registered with the Health and Care Professions Council (HCPC) and who held, or were studying for, a doctoral award. Results: A total of 90 unique responses were received within the timescale. The respondents comprised 58 females (64.4%) and the majority were diagnostic radiographers (n = 71/90; 78.9%). The traditional PhD was the most common award, although increasing numbers were pursuing Education or Professional Doctorates. An overall increase in doctoral studies is observed over time, but was greatest amongst those working in academic institutions, with 63.3% of respondents (n = 57/90) working solely within a university, and a further 10% employed in a clinical–academic role (n = 9/90). Conclusion: This study has demonstrated that radiography is emerging as a research active profession, with increasing numbers of radiographers engaged in study at a doctoral level. This should provide a platform for the future development of academic and clinical research. - Highlights: • 90 radiographers were identified as holding, or studying for, a doctoral award. • The PhD is the most common award. • EdD and professional doctorates are increasing in popularity. • Academic staff were more likely to pursue such research training.
Measurement approaches to support future warhead arms control transparency

Transparency on warhead stockpiles, warhead dismantlement, and fissile material stockpiles in nuclear weapons states will become increasingly important in the move beyond START II toward lower quantities of warheads. Congressional support for further warhead reductions will likely depend on the degree of irreversibility, or in other words, the rapidity with which warhead inventories could be reconstituted. Whether irreversibility considerations can be satisfied will depend on monitoring dismantlement as well as constraining the available stockpile of fissile materials for possible refabrication into warheads. Measurement techniques designed to address the above problems will need to consider NPT Article 1 obligations as well as Russian and US classification regulations, which prohibit or restrict the transfer of nuclear warhead design information to other states. Classification considerations currently limit the potential completeness of future inspections of weapons materials. Many conventional international safeguards approaches are not currently viable for arms control applications because they would reveal weapons design information. The authors discuss a variety of technical measures that may help to improve transparence of warhead and fissile material stockpiles and may enable limited warhead dismantlement transparency

Artists throughout the ages have discovered a number of techniques to depict transparency. With only a few exceptions, these techniques follow closely the properties of physical transparency. The two best known properties are X-junctions and the luminance relations described by Metelli. X-junctions are seen where the contours of a transparent material cross contours of the surface behind; Metelli's constraints on the luminance relations between the direct and filtered portions of the surface specify a range of luminance values that are consistent with transparency. These principles have been used by artists since the time of ancient Egypt. However, artists also discovered that stimuli can be seen as transparent even when these physical constraints are not met. Ancient Greek artists, for example, were able to depict transparent materials in simple black-and-white line drawings. Artists also learned how to represent transparency in cases where neither X-junctions nor Metelli's constraints could apply: for example, where no portions of the objects behind the transparent material extend beyond it. Many painters convincingly portrayed transparency in these cases by depicting the effects the transparent medium would have on material or object properties. Here, we show how artists employed these and other techniques revealing their anticipation of current formalizations of perceived transparency, and we suggest new, as-yet-untested principles.

Full Text Available Workshops and seminars are widely-used forms of doctoral training. However, research with a particular focus on these forms of doctoral training is sporadic in the literature. There is little, if any, such research concerning the international context and participants’ own voices. Mindful of these lacunae in the literature, we write the current paper as a group of participants in one of a series of doctoral forums co-organised annually by Beijing Normal University, China and Queensland University of Technology, Australia. The paper voices our own experiences of participation in the doctoral forum. Data were drawn from reflections, journals, and group discussions of all 12 student and academic participants. These qualitative data were organised and analysed through Bourdieu’s notions of capital and field. Findings indicate that the doctoral forum created enabling and challenging social fields where participants accrued and exchanged various forms of capital and negotiated transient and complex power relations. In this respect, the sociological framework used provides a distinctive theoretical tool to conceptualise and analyse the benefits and tensions of participation in the doctoral forum. Knowledge built and lessons learned through our paper will provide implications and recommendations for future planning of, and participation in, the doctoral forum series and similar activities elsewhere.

Weight and quality of medical doctoral theses have been discussed in Germany for years. Doctoral study programs in various graduate schools offer opportunities to improve quality of medical doctoral theses. The purpose of this study was to demonstrate distinctions and differences concerning motivation, choice of subject and the dissertation process between doctoral candidates completing the doctoral seminar for doctoral students in the Ludwig-Maximilians-University (LMU) Munich and doctoral candidates doing their doctorate individually. All 4000 medical students of the LMU obtained an online-questionnaire which was completed by 767 students (19 % response rate). The theoretical framework of this study was based upon the Self-Determination-Theory by Deci and Ryan. Doctoral candidates completing the doctoral study program were more intrinsically motivated than doctoral candidates doing their doctorate individually; no difference was found in their extrinsic motivation. In regard to choice of subject and dissertation process the doctoral students in the seminar were distinguished from the individual group by having chosen a more challenging project. They anticipated a demanding dissertation process including conference participation, publishing of papers, etc. Intrinsic motivation correlates positively with choosing a challenging project and a demanding dissertation process. High intrinsic motivation seems to be very important for autonomous scholarly practice. Our results suggest that doctoral study programs have a positive impact on intrinsic motivation and interest in research. © Georg Thieme Verlag KG Stuttgart · New York.

The spontaneous separation of a polymer thin film from a substrate is an innovative technology that will enable material recycling and reduce manufacturing cost in the film industry, and this can be applied in a wide range of applications, from optical films to wearable devices. Here, we present an unprecedented spontaneous strategy for separating transparent polymer films from substrates on the basis of microbubble generation using nanocapsules containing an evaporable material. The core-shell nanocapsules are prepared from poly(methyl methacrylate)-polyethyleneimine nanoparticles via the encapsulation of methylcyclohexane (MCH). A spherical nanostructure with a vaporizable core is obtained, with the heat-triggered gas release ability leading to the formation of microbubbles. Our separation method applied to transparent polymer films doped with a small amount of the nanocapsules encapsulating evaporable MCH enables spontaneous detachment of thin films from substrates via vacuum-assisted rapid vaporization of MCH over a short separation time, and clear detachment of the film is achieved with no deterioration of the inherent optical transparency and adhesive property compared to a pristine film.

In this analysis of the ethical dimensions of doctors' participation in macroallocation we set out to understand the skills they use, how they are acquired, and how they influence performance of the role. Using the principles of grounded moral analysis, we conducted a semi-structured interview study with Australian doctors engaged in macroallocation. We found that they performed expertise as argument, bringing together phronetic and rhetorical skills founded on communication, strategic thinking, finance, and health data. They had made significant, purposeful efforts to gain skills for the role. Our findings challenge common assumptions about doctors' preferences in argumentation, and reveal an unexpected commitment to practical reason. Using the ethics of Paul Ricoeur in our analysis enabled us to identify the moral meaning of doctors' skills and learning. We concluded that Ricoeur's ethics offers an empirically grounded matrix for ethical analysis of the doctor's role in macroallocation that may help to establish norms for procedure.
Plasmonic transparent conductors

Many of today's technological applications, such as solar cells, light-emitting diodes, displays, and touch screens, require materials that are simultaneously optically transparent and electrically conducting. Here we explore transparent conductors based on the excitation of surface plasmons in nanostructured metal films. We measure both the optical and electrical properties of films perforated with nanometer-scale features and optimize the design parameters in order to maximize optical transmission without sacrificing electrical conductivity. We demonstrate that plasmonic transparent conductors can out-perform indium tin oxide in terms of both their transparency and their conductivity.

Heat and Flux. Enabling the Wind Turbine Controller
Energy Technology Data Exchange (ETDEWEB)
Schaak, P. [ECN Wind Energy, Petten (Netherlands)
2006-09-15
In the years 1999-2003 ECN invented and patented the technique 'Heat and Flux'. The idea behind Heat and Flux is that tuning turbines at the windward side of a wind farm more transparent than usual, i.e. realising an axial induction factor below the Lanchester-Betz optimum of 1/3, should raise net farm production and lower mechanical turbine loading without causing draw-backs. For scaled farms in a boundary layer wind tunnel this hypothesis has been proved in previous projects. To enable alternative turbine transparencies, the wind turbine controller must support the additional control aim 'desired transparency'. During this study we have determined a general method to design a transparency control algorithm. This method has been implemented in ECN's 'Control Tool' for designing wind turbine control algorithms. The aero-elastic wind turbine code Phatas has been used to verify the resulting control algorithm. Heat and Flux does not fundamentally change the control of horizontal axis variable speed wind turbines. The axial induction can be reduced by an offset on blade pitch or generator torque. Weighing reliability against performance profits, it appeared to be advisable to adapt only blade angle control.

In this presentation, various problems surrounding the issues of transparency, such as 'What exactly should be transparent?' 'Is all that we want amounting only to transparency?' 'Is it possible to thoroughly implement transparency', etc., are discussed with due consideration for the viewpoints of the wide range of parties concerned involving areas of politics, administration, enterprises, media, individuals, and so on. First of all, the explanation is focused on how the transparency is recognised, as well as how it is regarded as important, for the public at large and the media. Then, based on the concept that transparency is required for what cannot be justified to be secret, we will contemplate what should be transparent in the areas of politics, administration and enterprises, using the case of nuclear issues as example. Next, the discussion will proceed to the point whether the achievement of transparency itself should be the ultimate goal, in the light of taking into consideration the standpoints of individuals and the receivers of the information, in addition to that of the administration, politics, and enterprises. In closing, we will discuss what the necessary measures will be to materialize the complete transparency on the basis of the discussions made thus far. (author)

Full Text Available Abstract Background In the United Kingdom, specialist treatment and intervention services for doctors are underdeveloped. The MedNet programme, created in 1997 and funded by the London Deanery, aims to fill this gap by providing a self-referral, face-to-face, psychotherapeutic assessment service for doctors in London and South-East England. MedNet was designed to be a low-threshold service, targeting doctors without formal psychiatric problems. The aim of this study was to delineate the characteristics of doctors utilising the service, to describe their psychological morbidity, and to determine if early intervention is achieved. Methods A cross-sectional study including all consecutive self-referred doctors (n = 121, 50% male presenting in 2002–2004 was conducted. Measures included standardised and bespoke questionnaires both self-report and clinician completed. The multi-dimensional evaluation included: demographics, CORE (CORE-OM, CORE-Workplace and CORE-A an instrument designed to evaluate the psychological difficulties of patients referred to outpatient services, Brief Symptom Inventory to quantify caseness and formal psychiatric illness, and Maslach Burnout Inventory. Results The most prevalent presenting problems included depression, anxiety, interpersonal, self-esteem and work-related issues. However, only 9% of the cohort were identified as severely distressed psychiatrically using this measure. In approximately 50% of the sample, problems first presented in the preceding year. About 25% were on sick leave at the time of consultation, while 50% took little or no leave in the prior 12 months. A total of 42% were considered to be at some risk of suicide, with more than 25% considered to have a moderate to severe risk. There were no significant gender differences in type of morbidity, severity or days off sick. Conclusion Doctors displayed high levels of distress as reflected in the significant proportion of those who were at some risk of

Balzac wrote his novels during a time of great literary and scientific change. Romanticism gave way to the school of realism, of which Balzac could be considered the founder. It was via realism, where both the positive and negative aspects of life were depicted, that doctors naturally gained a much more active role in novels. In conjunction with this was the development of science and medicine, which fascinated Balzac, also leading to the significant and prevalent role of doctors in his works. His fascination with the sciences led to him to gain many acquaintances and much knowledge in the medical domain, especially in neuropsychiatry and physiology. His fictional doctors, such as Desplein and Bianchon, thus demonstrate considerable knowledge of pathology, physiology, and neuropsychiatry. The doctors in Balzac's novels can be grouped into four categories: provincial doctors, Parisian doctors, country doctors, and military doctors. They were most often fictitious representations of real individuals (e.g. Guillaume Dupuytren), and often symbolize schools of thought which were in vogue at the time. In addition to the accurate scientific depiction of doctors, it must be noted that his doctors not only played an active role in clinically assessing their patients, but also had a sociological role in assessing society; it is through his doctors that Balzac gave his opinion of the world in which he lived.

Glass is one of the most important high-performance materials used for scientific research, in industry and in society, mainly owing to its unmatched optical transparency, outstanding mechanical, chemical and thermal resistance as well as its thermal and electrical insulating properties. However, glasses and especially high-purity glasses such as fused silica glass are notoriously difficult to shape, requiring high-temperature melting and casting processes for macroscopic objects or hazardous chemicals for microscopic features. These drawbacks have made glasses inaccessible to modern manufacturing technologies such as three-dimensional printing (3D printing). Using a casting nanocomposite, here we create transparent fused silica glass components using stereolithography 3D printers at resolutions of a few tens of micrometres. The process uses a photocurable silica nanocomposite that is 3D printed and converted to high-quality fused silica glass via heat treatment. The printed fused silica glass is non-porous, with the optical transparency of commercial fused silica glass, and has a smooth surface with a roughness of a few nanometres. By doping with metal salts, coloured glasses can be created. This work widens the choice of materials for 3D printing, enabling the creation of arbitrary macro- and microstructures in fused silica glass for many applications in both industry and academia.

Doctors’ relationship with patients and their role in society is changing. Until the 1960s doctors concentrated on the welfare of patients with less emphasis placed on patients’ rights1. Over recent decades there has been increasing empowerment of the individual across all facets of society including health care. Doctors continue to be perceived as having expertise and authority over medical science. Patients, however, now hold sway over questions of values or preferences. We all must be aware of this change in the doctor- patient interaction. We need to be more aware of the outcomes that patients view as important. The concept of shared decision-making with the patient is now widely appreciated. The process involves a change in mind set particularly for doctors who trained in an earlier era.

If doctors take the costs of treatment into account when prescribing medication, their objectives differ from their patients' objectives because the patients are insured. This misalignment of interests hampers communication between patient and doctor. Giving cost incentives to doctors increases...... welfare if (i) the doctor's examination technology is sufficiently good or (ii) (marginal) costs of treatment are high enough.

Homogeneous linewidths below 10 kHz are reported for the first time in high-quality Eu3+ doped Y 2O3 transparent ceramics. This result is obtained on the 7F0→5D0 transition in Eu3+ doped Y 2O3 ceramics and corresponds to an improvement of nearly one order of magnitude compared to previously reported values in transparent ceramics. Furthermore, we observed spectral hole lifetimes of ˜15 min that are long enough to enable efficient optical pumping of the nuclear hyperfine levels. Additionally, different Eu3+ concentrations (up to 1.0%) were studied, resulting in an increase of up to a factor of three in the peak absorption coefficient. These results suggest that transparent ceramics can be useful in applications where narrow and deep spectral holes can be burned into highly absorbing lines, such as quantum information processing and spectral filtering.

repository, the Waste Isolation Pilot Plant (WIPP) offers a unique opportunity to serve as an international cooperative test bed for developing and demonstrating technologies and processes in a fully operational repository system setting. To address the substantial national security implications for the US resulting from the lack of integrated, transparent management and disposition of nuclear materials at the back-end of the nuclear fuel and weapons cycles, it is proposed that WIPP be used as a test bed to develop and demonstrate technologies that will enable the transparent and proliferation-resistant geologic isolation of nuclear materials. The objectives of this initiative are to: (1) enhance public confidence in safe, secure geologic isolation of nuclear materials; (2) develop, test, and demonstrate transparency measures and technologies for the back-end of nuclear fuel cycle; and (3) foster international collaborations leading to workable, effective, globally-accepted standards for the transparent monitoring of geological repositories for nuclear materials. Test-bed activities include: development and testing of monitoring measures and technologies; international demonstration experiments; transparency workshops; visiting scientist exchanges; and educational outreach. These activities are proposed to be managed by the Department of Energy/Carlsbad Area Office (DOE/CAO) as part of The Center for Applied Repository and Underground Studies (CARUS)

Private and security information for personal identification requires an encrypted tool to extend communication channels between human and machine through a convenient and secure method. Here, a triboelectric-based transparent secret code (TSC) that enables self-powered sensing and information identification simultaneously in a rapid process method is reported. The transparent and hydrophobic TSC can be conformed to any cambered surface due to its high flexibility, which extends the application scenarios greatly. Independent of the power source, the TSC can induce obvious electric signals only by surface contact. This TSC is velocity-dependent and capable of achieving a peak voltage of ≈4 V at a resistance load of 10 MΩ and a sliding speed of 0.1 m s -1 , according to a 2 mm × 20 mm rectangular stripe. The fabricated TSC can maintain its performance after reciprocating rolling for about 5000 times. The applications of TSC as a self-powered code device are demonstrated, and the ordered signals can be recognized through the height of the electric peaks, which can be further transferred into specific information by the processing program. The designed TSC has great potential in personal identification, commodity circulation, valuables management, and security defense applications.

Doctor-patient communication is an interpersonal process and essential to relationship-centered care. However, in many studies, doctors and patients are studied as if living in separate worlds. This study assessed whether: 1) doctors' perception of their communication skills is congruent with their patients' perception; and 2) patients of a specific doctor agree with each other about their doctor's communication skills. A cross-sectional study was conducted in three provinces in Canada with 91 doctors and their 1749 patients. Doctors and patients independently completed questions on the doctor's communication skills (content and process) after a consultation. Multilevel modeling provided an estimate of the patient and doctor variance components at both the dyad-level and the doctor-level. We computed correlations between patients' and doctors' perceptions at both levels to assess how congruent they were. Consensus among patients of a specific doctor was assessed using intraclass correlation coefficient (ICC). The mean score of the rating of doctor's skills according to patients was 4.58, and according to doctors was 4.37. The dyad-level variance for the patient was .38 and for the doctor was .06. The doctor-level variance for the patient ratings was .01 and for the doctor ratings, .18. The correlation between both the patients' and the doctors' skills' ratings scores at the dyad-level was weak. At the doctor-level, the correlation was not statistically significant. The ICC for patients' ratings was .03 and for the doctors' ratings .76. Overall, this study suggests that doctors and their patients have a very different perspective of the doctors' communication skills occurring during routine clinical encounters. 2009 Elsevier Ltd.

Emergence of highly transparent photovoltaics for distributed applications
Traverse, Christopher J.; Pandey, Richa; Barr, Miles C.; Lunt, Richard R.
2017-11-01
Solar energy offers a viable solution to our growing energy need. While adoption of conventional photovoltaics on rooftops and in solar farms has grown rapidly in the last decade, there is still plenty of opportunity for expansion. See-through solar technologies with partial light transmission developed over the past 30 years have initiated methods of integration not possible with conventional modules. The large-scale deployment necessary to offset global energy consumption could be further accelerated by developing fully invisible solar cells that selectively absorb ultraviolet and near-infrared light, allowing many of the surfaces of our built environment to be turned into solar harvesting arrays without impacting the function or aesthetics. Here, we review recent advances in photovoltaics with varying degrees of visible light transparency. We discuss the figures of merit necessary to characterize transparent photovoltaics, and outline the requirements to enable their widespread adoption in buildings, windows, electronic device displays, and automobiles.

Membrane proteins involved in transport processes are key targets for pharmaceutical research and industry. Despite continuous improvements and new developments in the field of electrical readouts for the analysis of transport kinetics, a well-suited methodology for high-throughput characterization of single transporters with nonionic substrates and slow turnover rates is still lacking. Here, we report on a novel architecture of silicon chips with embedded nanopore microcavities, based on a silicon-on-insulator technology for high-throughput optical readouts. Arrays containing more than 14 000 inverted-pyramidal cavities of 50 femtoliter volumes and 80 nm circular pore openings were constructed via high-resolution electron-beam lithography in combination with reactive ion etching and anisotropic wet etching. These cavities feature both, an optically transparent bottom and top cap. Atomic force microscopy analysis reveals an overall extremely smooth chip surface, particularly in the vicinity of the nanopores, which exhibits well-defined edges. Our unprecedented transparent chip design provides parallel and independent fluorescent readout of both cavities and buffer reservoir for unbiased single-transporter recordings. Spreading of large unilamellar vesicles with efficiencies up to 96% created nanopore-supported lipid bilayers, which are stable for more than 1 day. A high lipid mobility in the supported membrane was determined by fluorescent recovery after photobleaching. Flux kinetics of α-hemolysin were characterized at single-pore resolution with a rate constant of 0.96 ± 0.06 × 10 -3 s -1 . Here, we deliver an ideal chip platform for pharmaceutical research, which features high parallelism and throughput, synergistically combined with single-transporter resolution.
Fabrication and comparison of selective, transparent optics for concentrating solar systems
Taylor, Robert A.; Hewakuruppu, Yasitha; DeJarnette, Drew; Otanicar, Todd P.
2015-09-01
Concentrating optics enable solar thermal energy to be harvested at high temperature (solar) wavelengths, but highly reflective at long (thermal emission) wavelengths. If a solar system requires an analogous transparent, non-absorbing optic - i.e. a cover material which is highly transparent at short wavelengths, but highly reflective at long wavelengths - the technology is simply not available. Low-e glass technology represents a commercially viable option for this sector, but it has only been optimized for visible light transmission. Optically thin metal hole-arrays are another feasible solution, but are often difficult to fabricate. This study investigates combinations of thin film coatings of transparent conductive oxides and nanoparticles as a potential low cost solution for selective solar covers. This paper experimentally compares readily available materials deposited on various substrates and ranks them via an `efficiency factor for selectivity', which represents the efficiency of radiative exchange in a solar collector. Out of the materials studied, indium tin oxide and thin films of ZnS-Ag-ZnS represent the most feasible solutions for concentrated solar systems. Overall, this study provides an engineering design approach and guide for creating scalable, selective, transparent optics which could potentially be imbedded within conventional low-e glass production techniques.

Films comprising nanofibrillated cellulose (NFC) are suitable substrates for flexible devices in analytical, sensor, diagnostic, and display technologies. However, some major challenges in such developments include their high moisture sensitivity and the complexity of current methods available for functionalization and patterning. In this work, we present a facile process for tailoring the surface wettability and functionality of NFC films by a fast and versatile approach. First, the NFC films were coated with a layer of reactive nanoporous silicone nanofilament by polycondensation of trichlorovinylsilane (TCVS). The TCVS afforded reactive vinyl groups, thereby enabling simple UV-induced functionalization of NFC films with various thiol-containing molecules via the photo "click" thiol-ene reaction. Modification with perfluoroalkyl thiols resulted in robust superhydrophobic surfaces, which could then be further transformed into transparent slippery lubricant-infused NFC films that displayed repellency against both aqueous and organic liquids with surface tensions as low as 18 mN·m -1 . Finally, transparent and flexible NFC films incorporated hydrophilic micropatterns by modification with OH, NH 2 , or COOH surface groups, enabling space-resolved superhydrophobic-hydrophilic domains. Flexibility, transparency, patternability, and perfect superhydrophobicity of the produced nanocellulose substrates warrants their application in biosensing, display protection, and biomedical and diagnostics devices.

Political polarization and past fiscal conditions, in particular state government debt...... and budget imbalance, also appear to affect the level of transparency...
Doctors and pharmaceutical industry.
Beran, Roy G
2009-09-01
The pharmaceutical industry is seen as seducing doctors by providing expensive gifts, subsidising travel and underwriting practice expenses in return for those doctors prescribing products that otherwise they would not use. This paints doctors in a very negative light; suggests doctors are available to the highest bidder; implies doctors do not adequately act as independent agents; and that doctors are driven more by self-interest than by patient needs. Similar practices, in other industries, are accepted as normal business behaviour but it is automatically assumed to be improper if the pharmaceutical industry supports doctors. Should the pharmaceutical industry withdraw educational grants then there would be: fewer scientific meetings; reduced attendance at conferences; limited post graduate education; and a depreciated level of maintenance of professional standards. To suggest that doctors prescribe inappropriately in return for largesse maligns their integrity but where there is no scientific reason to choose between different treatments then there can be little argument against selecting the product manufactured by a company that has invested in the doctor and the question arises as to whether this represents bad medicine? This paper will examine what constitutes non-professional conduct in response to inducements by the pharmaceutical industry. It will review: conflict of interest; relationships between doctors and pharma and the consequences for patients; and the need for critical appraisal before automatically decrying this relationship while accepting that there remain those who do not practice ethical medicine.

The Doctoral Degree in Dental Hygiene: Creating New Oral Healthcare Paradigms.
Gurenlian, JoAnn R; Rogo, Ellen J; Spolarich, Ann Eshenaur
2016-06-01
Doctoral dental hygiene education would prepare scholars and leaders to improve population health through changes in oral health policy and delivery. Discussions about doctoral education in dental hygiene have centered on the need to create a cadre of dental hygiene researchers and scholars who will expand the body of knowledge for the profession. It has been proposed that scholars are needed to lead the development of theory and disseminate knowledge unique to the discipline of dental hygiene. Transformation to doctoral education is not a new trend as many other health care disciplines have already implemented curricular models, establishing the doctoral degree for entry level into practice. The Institute of Medicine has called for the exploration of new models for care delivery. Dental hygienists need to be prepared with leadership skills enabling them to participate and lead interprofessional teams and develop policies designed to improve the delivery of oral health care services to enhance population health. Current educational models do not adequately prepare dental hygienists to serve in this capacity. The purpose of this article is to present 2 models of doctoral education for dental hygiene that will illustrate how dental hygienists can be better prepared as scholars and leaders for the profession. These proposed models of doctoral education in dental hygiene present a paradigm shift in dental hygiene education. As with other disciplines that have evolved, both academically and professionally, dental hygiene will be positioned to achieve the hallmark of professional status with this terminal degree.

Transparent solutions of nanocrystals exhibit many unique properties, and are thus attractive materials for numerous applications. However, the synthesis of transparent nanocrystal solutions of magnesium hydroxide (MH) with wide applications is yet to be realized. Here, we report a facile two-step process, which includes a direct reactive precipitation in alcohol phase instead of aqueous phase combined with a successive surface modification, to prepare transparent alcohol solutions containing lamellar MH nanocrystals with an average size of 52 nm and an ultrathin thickness of 1–2 nm, which is the thinnest MH nanoplatelet reported in the literatures. Further, highly flexible and transparent nanocomposite films are fabricated with a solution mixing method by adding the transparent MH nanocrystal solutions into PVB solution. Considering the simplicity of the fabrication process, high transparency and good flexibility, this MH/polymer nanocomposite film is promising for flame-resistant applications in plastic electronics and optical devices with high transparency, such as flexible displays, optical filters, and flexible solar cells.

We report that addition of small amounts of conjugated polymer to nanotube dispersions enables straightforward fabrication of uniform network electrodes by spin-coating and simultaneous tuning of parameters such as bundle size and density. After treatment in thionyl chloride, electrodes have sheet resistances competitive with other reported carbon nanotube based transparent electrodes to date. © 2009 American Chemical Society.

Mirage effect from thermally modulated transparent carbon nanotube sheets.
Aliev, Ali E; Gartstein, Yuri N; Baughman, Ray H
2011-10-28
The single-beam mirage effect, also known as photothermal deflection, is studied using a free-standing, highly aligned carbon nanotube aerogel sheet as the heat source. The extremely low thermal capacitance and high heat transfer ability of these transparent forest-drawn carbon nanotube sheets enables high frequency modulation of sheet temperature over an enormous temperature range, thereby providing a sharp, rapidly changing gradient of refractive index in the surrounding liquid or gas. The advantages of temperature modulation using carbon nanotube sheets are multiple: in inert gases the temperature can reach > 2500 K; the obtained frequency range for photothermal modulation is ~100 kHz in gases and over 100 Hz in high refractive index liquids; and the heat source is transparent for optical and acoustical waves. Unlike for conventional heat sources for photothermal deflection, the intensity and phase of the thermally modulated beam component linearly depends upon the beam-to-sheet separation over a wide range of distances. This aspect enables convenient measurements of accurate values for thermal diffusivity and the temperature dependence of refractive index for both liquids and gases. The remarkable performance of nanotube sheets suggests possible applications as photo-deflectors and for switchable invisibility cloaks, and provides useful insights into their use as thermoacoustic projectors and sonar. Visibility cloaking is demonstrated in a liquid.

Living Donor Liver Transplant is not a Transparent Activity in India.
Naidu, Sudeep
2013-03-01
Living donor liver transplant has gained rapid popularity in India as a life saving procedure for end stage liver disease. The undoubted benefit for the recipient is clouded by a few unfavorable outcomes in donors which have led to allegations of lack of transparency. These factors are easily remediable with an attitude of self audit and self disclosure by transplant centers, enabling a truly informed consenting procedure.

X-ray transparent Microfluidics for Protein Crystallization and Biomineralization
Opathalage, Achini
Protein crystallization demands the fundamental understanding of nucleation and applying techniques to find the optimal conditions to achieve the kinetic pathway for a large and defect free crystal. Classical nucleation theory predicts that the nucleation occurs at high supersaturation conditions. In this dissertation we sought out to develop techniques to attain optimal supersaturation profile to a large defect free crystal and subject it to in-situ X-ray diffraction using microfluidics. We have developed an emulsion-based serial crystallographic technology in nanolitre-sized droplets of protein solution encapsulated in to nucleate one crystal per drop. Diffraction data are measured, one crystal at a time, from a series of room temperature crystals stored on an X-ray semi-transparent microfluidic chip, and a 93% complete data set is obtained by merging single diffraction frames taken from different un-oriented crystals. As proof of concept, the structure of Glucose Isomerase was solved to 2.1 A. We have developed a suite of X-ray semi-transparent micrfluidic devices which enables; controlled evaporation as a method of increasing supersaturation and manipulating the phase space of proteins and small molecules. We exploited the inherently high water permeability of the thin X-ray semi-transparent devices as a mean of increasing the supersaturation by controlling the evaporation. We fabricated the X-ray semi-transparent version of the PhaseChip with a thin PDMS membrane by which the storage and the reservoir layers are separated, and studies the phase transition of amorphous CaCO3.

Full Text Available This paper explains passive collection of solar radiation energy using transparent thermal insulators. Transparent thermal insulators are transparent for sunlight, at the same time those are very good thermal insulators. Transparent thermal insulators can be placed instead of standard conventional thermal insulators and additionally transparent insulators can capture solar radiation, transform it into heat and save heat just as standard insulators. Using transparent insulators would lead to reduce in usage of fossil fuels and would help protection of an environment and reduce effects of global warming, etc.

Polyisobutylene having a viscosity average molecular weight of 20,000 to 80,000 and a hydrogen atom density of greater than 7.0 x 10 22 /cm 3 is used as a fast neutron shielding material. The shielding material is excellent in the shielding performance against fast neutrons, and there is no worry of leakage even when holes should be formed to a vessel. Further, it is excellent in fabricability, relatively safe even upon occurrence of fire and, in addition, it is transparent to enable to observe contents easily. (T.M.)

This paper analyses different transparency aspects regarding European wholesale electricity markets and discusses transparency issues to be solved. In Europe, currently some progress has been made with respect to market transparency but transparency issues related to transmission, system operation and regulation have received little attention so far. Transmission system operators (TSOs) and regulatory authorities need certain market information in order to secure efficient competition. However, TSOs and regulatory authorities need to communicate themselves in order to facilitate competition and decrease uncertainty among market participants. Furthermore, considering ongoing market integration both TSOs and regulatory authorities must exchange information amongst themselves in order to facilitate coordination and monitoring activities. The effect of a higher level of transparency on effective competition is depended on two categories of transparency aspects: aspects that are related to transparency in the sense of open and adequate communication (perspicuity) and aspects that are related to the easiness to understand (clarity). Transparency includes both aspects. Pursuing overall harmonization of the European transparency level is important to fully profit from a higher level of (international) harmonization. Effective harmonization requires harmonization on all communication aspects. For Europe, with its many immature markets, the dilemma remains whether it is preferable to have less transparency with a high level of harmonization or to have a higher level of transparency but a lower level of harmonization.

Albu, Oana Brindusa; Flyverbom, Mikkel
Transparency is a distinctive area of research across disciplines and presents significant importance for organization studies. However, transparency is rarely subject to structured and critical scrutiny and as a result its relevance for organizational analysis is underestimated. In an attempt...... to foreground the value of transparency studies, we offer an overview of the existing research and indicate two paradigmatic positions underpinning the transparency literature, namely what we term non-performative and performative approaches. The main contribution of the paper lies in this ground......, an approach which remains underexplored. Finally, we discuss some avenues for future studies of the organizing properties of transparency: the secrecy-transparency interplay, the power-transparency nexus and the transparency ‘family tree’ (i.e., intersections between multiple forms of disclosure)....

Perceptual transparency from image deformation.
Kawabe, Takahiro; Maruya, Kazushi; Nishida, Shin'ya
2015-08-18
Human vision has a remarkable ability to perceive two layers at the same retinal locations, a transparent layer in front of a background surface. Critical image cues to perceptual transparency, studied extensively in the past, are changes in luminance or color that could be caused by light absorptions and reflections by the front layer, but such image changes may not be clearly visible when the front layer consists of a pure transparent material such as water. Our daily experiences with transparent materials of this kind suggest that an alternative potential cue of visual transparency is image deformations of a background pattern caused by light refraction. Although previous studies have indicated that these image deformations, at least static ones, play little role in perceptual transparency, here we show that dynamic image deformations of the background pattern, which could be produced by light refraction on a moving liquid's surface, can produce a vivid impression of a transparent liquid layer without the aid of any other visual cues as to the presence of a transparent layer. Furthermore, a transparent liquid layer perceptually emerges even from a randomly generated dynamic image deformation as long as it is similar to real liquid deformations in its spatiotemporal frequency profile. Our findings indicate that the brain can perceptually infer the presence of "invisible" transparent liquids by analyzing the spatiotemporal structure of dynamic image deformation, for which it uses a relatively simple computation that does not require high-level knowledge about the detailed physics of liquid deformation.

A flexible, transparent, chemical gas sensor is assembled from a transparent conducting film of carbon nanotube (CNT) networks that are coated with hierarchically nanostructured polyaniline (PANI) nanorods. The nanocomposite film is synthesized by in-situ, chemical oxidative polymerization of aniline in a functional multiwalled CNT (FMWCNT) suspension and is simultaneously deposited onto a flexible polyethylene terephthalate (PET) substrate. An as-prepared flexible transparent chemical gas sensor exhibits excellent transparency of 85.0% at 550 nm using the PANI/FMWCNT nanocomposite film prepared over a reaction time of 8 h. The sensor also shows good flexibility, without any obvious decrease in performance after 500 bending/extending cycles, demonstrating high-performance, portable gas sensing at room temperature. This superior performance could be attributed to the improved electron transport and collection due to the CNTs, resulting in reliable and efficient sensing, as well as the high surface-to-volume ratio of the hierarchically nanostructured composites. The excellent transparency, improved sensing performance, and superior flexibility of the device, may enable the integration of this simple, low-cost, gas sensor into handheld flexible transparent electronic circuitry and optoelectronic devices. © 2015 WILEY-VCH Verlag GmbH & Co.

What color transparency measures

Color transparency is commonly accepted to be a prediction of perturbative QCD. However it is more a phenomenon probing the interface between the perturbative and nonperturbative regimes, leading to some intricacy in its theoretical description. In this paper we study the consequences of the impulse approximation to the theory in various quantum mechanical bases. We show that the fully interacting hadronic basis, which consists of eigenstates of the exact Hamiltonian in the presence of the nucleus, provides a natural basis to study color transparency. In this basis we can relate the quark wave function at a small transverse separation distance b 2 2 directly to transparency ratios measured in experiment. With the formalism, experiment can be used to map out the quark wave function in this region. We exhibit several loopholes in existing arguments predicting a rise in transparency ratios with energy, and suggest alternatives. Among the results, we argue that the theoretical prediction of a rising transparency ratio with energy may be on better footing for heavy-quark bound states than for relativistic light-quark systems. We also point out that transparency ratios can be constant with energy and not at variance with perturbative QCD

Semi-transparent solar cells are a type of technology that combines the benefits of visible light transparency and light-to-electricity conversion. One of the biggest opportunities for such technologies is in their integration as windows and skylights within energy-sustainable buildings. Currently, such building integrated photovoltaics (BIPV) are dominated by crystalline silicon based modules; however, the opaque nature of silicon creates a unique opportunity for the adoption of emerging photovoltaic candidates that can be made truly semi-transparent. These include: amorphous silicon-, kesterite-, chalcopyrite-, CdTe-, dye-sensitized-, organic- and perovskite- based systems. For the most part, amorphous silicon has been the workhorse in the semi-transparent solar cell field owing to its established, low-temperature fabrication processes. Excitement around alternative classes, particularly perovskites and the inorganic candidates, has recently arisen because of the major efficiency gains exhibited by these technologies. Importantly, each of these presents unique opportunities and challenges within the context of BIPV. This topic review provides an overview into the broader benefits of semi-transparent solar cells as building-integrated features, as well as providing the current development status into all of the major types of semi-transparent solar cells technologies.

Lignin-Retaining Transparent Wood.

Optically transparent wood, combining optical and mechanical performance, is an emerging new material for light-transmitting structures in buildings with the aim of reducing energy consumption. One of the main obstacles for transparent wood fabrication is delignification, where around 30 wt % of wood tissue is removed to reduce light absorption and refractive index mismatch. This step is time consuming and not environmentally benign. Moreover, lignin removal weakens the wood structure, limiting the fabrication of large structures. A green and industrially feasible method has now been developed to prepare transparent wood. Up to 80 wt % of lignin is preserved, leading to a stronger wood template compared to the delignified alternative. After polymer infiltration, a high-lignin-content transparent wood with transmittance of 83 %, haze of 75 %, thermal conductivity of 0.23 W mK -1 , and work-tofracture of 1.2 MJ m -3 (a magnitude higher than glass) was obtained. This transparent wood preparation method is efficient and applicable to various wood species. The transparent wood obtained shows potential for application in energy-saving buildings. © 2017 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.

Imagine shooting a beam of protons of high momentum P through an atomic nucleus. Usually the nuclear interactions prevent the particles from emerging with momentum ∼P. Further, the angular distribution of elastically scattered protons is close to the optical diffraction pattern produced by a black disk. Thus the nucleus acts as a black disk and is not transparent. However, certain high momentum transfer reactions in which a proton is knocked out of the nucleus may be completely different. Suppose that the high momentum transfer process leads to the formation of a small-size color singlet wavepacket that is ejected from the nucleus. The effects of gluons emitted by color singlet systems of closely separated quarks and gluons tend to cancel. Thus the wavepacket-nuclear interactions are suppressed, the nucleus becomes transparant and one says that color transparency CT occurs. The observation of CT also requires that the wavepacket not expand very much while it moves through the nucleus. Simple quantum mechanical formulations can assess this expansion. The creation of a small-sized wavepacket is expected in asymptotic perturbative effects. The author reviews the few experimental attempts to observe color transparency in nuclear (e,e'p) and (p,pp) reactions and interpret the data and their implications

Quality health care is an issue of concern worldwide, and nursing can and must play a major and global role in transforming the healthcare environment. Doctorally prepared nurses are very much needed in the discipline to further develop and expand the science, as well as to prepare its future educators, scholars, leaders, and policy makers. In 1968, the Master of Science in Nursing Program was initiated in Turkey, followed by the Nursing Doctoral Education Program in 1972. Six University Schools of Nursing provide nursing doctoral education. By the graduating year of 2001, 154 students had graduated with the Doctor of Philosophy in Nursing (Ph.D.), and 206 students were enrolled in related courses. Many countries in the world are systematically building various collaborative models in their nursing doctoral education programs. Turkey would like to play an active role in creating collaborative nursing doctoral education programs with other countries. This paper centres on the structure and model of doctoral education for nurses in Turkey. It touches on doctoral programs around the world; describes in detail nursing doctoral education in Turkey, including its program structure, admission process, course units, assessment strategies and dissertation procedure; and discusses efforts to promote Turkey as a potential partner in international initiatives to improve nursing doctoral education.

The Canadian Nuclear Safety Commission's mission is to regulate the use of nuclear energy and materials to protect the health, safety, and security of Canadians and the environment, as well as to respect Canada's international commitments on the peaceful use of nuclear energy. In 2001, the CNSC established a vision to be one of the best nuclear regulators in the world and established four strategic priorities of effectiveness, transparency, excellence in staff, and efficiency. While fulfilling a very comprehensive mandate, the CNSC operates with a. very clear vision of its clientele - the Canadian people. That commitment guides every employee and every action of the CNSC and ensures a firm commitment to transparency. The presentation will begin with a brief overview of the worldwide context of transparency and transparency measurement, with a look at what lessons can be learned from other organizations and initiatives. It will look broadly at the Canadian context and the government framework that establishes transparency, including the keystone legislation of the Access to Information Act. The presentation will then focus on the Canadian Nuclear Safety Commission. The CNSC is firmly committed to putting additional measures in place to ensure transparency, which is being done concurrently with an overall organisational performance measurement system. It is within this framework that the presentation will address the transparency efforts at the CNSC as well transparency measurement activities. And, finally, the presentation will look at future directions for transparency and its measurement at the CNSC. (author)
Mobile health IT: the effect of user interface and form factor on doctor-patient communication.
Alsos, Ole Andreas; Das, Anita; Svanæs, Dag
2012-01-01
Introducing computers into primary care can have negative effects on the doctor-patient dialogue. Little is known about such effects of mobile health IT in point-of-care situations. To assess how different mobile information devices used by physicians in point-of-care situations support or hinder aspects of doctor-patient communication, such as face-to-face dialogue, nonverbal communication, and action transparency. The study draws on two different experimental simulation studies where 22 doctors, in 80 simulated ward rounds, accessed patient-related information from a paper chart, a PDA, and a laptop mounted on a trolley. Video recordings from the simulations were analyzed qualitatively. Interviews with clinicians and patients were used to triangulate the findings and to verify the realism and results of the simulations. The paper chart afforded smooth re-establishment of eye contact, better verbal and non-verbal contact, more gesturing, good visibility of actions, and quick information retrieval. The digital information devices lacked many of these affordances; physicians' actions were not visible for the patients, the user interfaces required much attention, gesturing was harder, and re-establishment of eye contact took more time. Physicians used the devices to display their actions to the patients. The analysis revealed that the findings were related to the user interface and form factor of the information devices, as well as the personal characteristics of the physician. When information is needed and has to be located at the point-of-care, the user interface and the physical form factor of the mobile information device are influential elements for successful collaboration between doctors and patients. Both elements need to be carefully designed so that physicians can use the devices to support face-to-face dialogue, nonverbal communication, and action visibility. The ability to facilitate and support the doctor-patient collaboration is a noteworthy usability
Positron annihilation in transparent ceramics

Transparent ceramics are emerging as excellent candidates for many photonic applications including laser, scintillation and illumination. However achieving perfect transparency is essential in these applications and requires high technology processing and complete understanding for the ceramic microstructure and its effect on the optical properties. Positron annihilation spectroscopy (PAS) is the perfect tool to study porosity and defects. It has been applied to investigate many ceramic structures; and transparent ceramics field may be greatly advanced by applying PAS. In this work positron lifetime (PLT) measurements were carried out in parallel with optical studies on yttrium aluminum garnet transparent ceramics in order to gain an understanding for their structure at the atomic level and its effect on the transparency and light scattering. The study confirmed that PAS can provide useful information on their microstructure and guide the technology of manufacturing and advancing transparent ceramics.

For applications such as solar cells and displays, transparent single-crystal Si membranes were fabricated on a silicon-on-insulator (SOI) wafer. The SOI wafer included a buried layer of SiO 2 and Si 3 N 4 as an etch-stop layer. The etch-stop layer enabled fabrication of transparent single-crystal Si membranes with various thicknesses, and the thinning technology is described. For membranes with thicknesses of 18, 72 and 5000 nm, the respective optical transparent were 96.9%, 93.7% and 9% for R (red, λ = 660 nm), 96.9%, 91.4% and 1% for G (green, λ = 525 nm), and 97.0%, 93.2% and 0% for B (blue, λ = 470 nm). Organic light-emitting diodes (OLEDs) were then fabricated on transparent single-crystal Si membranes with various top Si thicknesses. OLEDs fabricated on 18, 72 and 5000 nm thick membranes and operated at 6 V demonstrated a luminance of 1350, 443 and 27 cd m -2 at the current densities of 148, 131 and 1.5 mA cm -2 , respectively.

2017-03-30
With the development of new generations of optoelectronic devices that combine high performance and novel functionalities (e.g., flexibility/bendability, adaptability, semi or full transparency), several classes of transparent electrodes have been developed in recent years. These range from optimized transparent conductive oxides (TCOs), which are historically the most commonly used transparent electrodes, to new electrodes made from nano- and 2D materials (e.g., metal nanowire networks and graphene), and to hybrid electrodes that integrate TCOs or dielectrics with nanowires, metal grids, or ultrathin metal films. Here, the most relevant transparent electrodes developed to date are introduced, their fundamental properties are described, and their materials are classified according to specific application requirements in high efficiency solar cells and flexible organic light-emitting diodes (OLEDs). This information serves as a guideline for selecting and developing appropriate transparent electrodes according to intended application requirements and functionality.

[Job satisfaction among Norwegian doctors].
Nylenna, Magne; Aasland, Olaf Gjerløw
2010-05-20
Doctors' job satisfaction has been discussed internationally in recent years based on reports of increasing professional dissatisfaction. We have studied Norwegian doctors' job satisfaction and their general satisfaction with life. A survey was conducted among a representative sample of practicing Norwegian doctors in 2008. The validated 10-item Job Satisfaction Scale was used to assess job satisfaction. 1,072 (65 %) doctors responded. They reported a mean job satisfaction of 5.3 on a scale from 1 (very dissatisfied) to 7 (very satisfied). Job satisfaction increased with increasing age. Private practice specialists reported the highest level of job satisfaction (5.8), and general practitioners reported higher job satisfaction (5.5) than hospital doctors (5.1). Among specialty groups, community doctors scored highest (5.6) and doctors in surgical disciplines lowest (5.0). While long working hours was negatively correlated with job satisfaction, the perception of being professionally updated and having part-time affiliation(s) in addition to a regular job were positively correlated with job satisfaction. 52.9 % of doctors reported a very high general satisfaction. Norwegian doctors have a high level of job satisfaction. Satisfaction with life in general is also high and at least in line with that in the Norwegian population.

Tates, K.; Meeuwesen, L.; Elbers, E.; Bensing, J.
2002-01-01
Previous studies on doctor-parent-child communication at the general practitioners surgery showed that the GP and the parent differ fundamentally in the way they enable or constrain child participation. The question how to explain these differences is at the core of the present study. The aim is

Asamenew Demessie Bireda
2015-11-01
Full Text Available This study aimed to investigate some challenges female doctoral students experience in their doctoral journey. The study used a qualitative design and structured interviews. The theoretical framework that guided the study was that of Urie Bronfenbrenner’s ecosystemic theory. A purposely selected sample of five female doctoral students from the University of South Africa Ethiopia campus participated in the study. The results identified three major areas of concern such as: academic, psychosocial and home/work related. Specifically, female doctoral students reported concerns surrounding quality of supervision support, inadequate academic skill, nature or system of education, stress, motivation, isolation, balancing personal and professional life, relationship problems, home and work related concerns. Hence, universities must provide opportunities and resourceful strategies to meet the challenges posed by women scholars in the doctoral journey.
Aerosol jet printed silver nanowire transparent electrode for flexible electronic application

Aerosol jet printing technology enables fine feature deposition of electronic materials onto low-temperature, non-planar substrates without masks. In this work, silver nanowires (AgNWs) are proposed to be printed into transparent flexible electrodes using a Maskless Mesoscale Material Deposition Aerosol Jet® printing system on a glass substrate. The influence of the most significant process parameters, including printing cycles, printing speed, and nozzle size, on the performance of AgNW electrodes was systematically studied. The morphologies of printed patterns were characterized by scanning electron microscopy, and the transmittance was evaluated using an ultraviolet-visible spectrophotometer. Under optimum conditions, high transparent AgNW electrodes with a sheet resistance of 57.68 Ω/sq and a linewidth of 50.9 μm were obtained, which is an important step towards a higher performance goal for flexible electronic applications.

Silver nanowire (AgNW) networks are considered to be promising structures for use as flexible transparent electrodes for various optoelectronic devices. One important application of AgNW transparent electrodes is the flexible touch screens. However, the performances of flexible touch screens are still limited by the large surface roughness and low electrical to optical conductivity ratio of random network AgNW electrodes. In addition, although the perception of writing force on the touch screen enables a variety of different functions, the current technology still relies on the complicated capacitive force touch sensors. This paper demonstrates a simple and high-throughput bar-coating assembly technique for the fabrication of large-area (>20 × 20 cm 2 ), highly cross-aligned AgNW networks for transparent electrodes with the sheet resistance of 21.0 Ω sq -1 at 95.0% of optical transmittance, which compares favorably with that of random AgNW networks (sheet resistance of 21.0 Ω sq -1 at 90.4% of optical transmittance). As a proof of concept demonstration, we fabricate flexible, transparent, and force-sensitive touch screens using cross-aligned AgNW electrodes integrated with mechanochromic spiropyran-polydimethylsiloxane composite film. Our force-sensitive touch screens enable the precise monitoring of dynamic writings, tracing and drawing of underneath pictures, and perception of handwriting patterns with locally different writing forces. The suggested technique provides a robust and powerful platform for the controllable assembly of nanowires beyond the scale of conventional fabrication techniques, which can find diverse applications in multifunctional flexible electronic and optoelectronic devices.
Doctor coach: a deliberate practice approach to teaching and learning clinical skills.
Gifford, Kimberly A; Fall, Leslie H
2014-02-01
The rapidly evolving medical education landscape requires restructuring the approach to teaching and learning across the continuum of medical education. The deliberate practice strategies used to coach learners in disciplines beyond medicine can also be used to train medical learners. However, these deliberate practice strategies are not explicitly taught in most medical schools or residencies. The authors designed the Doctor Coach framework and competencies in 2007-2008 to serve as the foundation for new faculty development and resident-as-teacher programs. In addition to teaching deliberate practice strategies, the programs model a deliberate practice approach that promotes the continuous integration of newly developed coaching competencies by participants into their daily teaching practice. Early evaluation demonstrated the feasibility and efficacy of implementing the Doctor Coach framework across the continuum of medical education. Additionally, the Doctor Coach framework has been disseminated through national workshops, which have resulted in additional institutions applying the framework and competencies to develop their own coaching programs. Design of a multisource evaluation tool based on the coaching competencies will enable more rigorous study of the Doctor Coach framework and training programs and provide a richer feedback mechanism for participants. The framework will also facilitate the faculty development needed to implement the milestones and entrustable professional activities in medical education.
Gaining a Doctorate in Nursing in Chile: a path not without its difficulties
Valenzuela-Suazo, Sandra; Sanhueza-Alvarado, Olivia
2015-01-01
OBJECTIVE: to analyze in detail the current situation of doctorate training in Nursing in Chile. METHODOLOGY: through a historical and contextual analysis of the background to the development of postgraduate education in Nursing, especially at doctorate level. RESULTS: aspects that limit development were identified in national institutionalism of the sciences as well as in higher education and health institutions, especially the limited value placed on nursing as an area of knowledge in this country, the lack of clear institutional policies for postgraduate studies, as well as the postgraduate's re-inclusion into the academic and care area, with access to national research funds difficult. FINAL CONSIDERATIONS: access to grants and funds, together with recognition as an area of knowledge belonging on academic schedules, especially in health institutions, are the main challenges to consolidation. One aspect that would enable a more rapid advance is through national and international inter-institutional agreements, adding together potential, with access to funds for studies and academic and student internships, enabling joint research to go ahead.

There is a demand for non-traditional doctoral education in healthcare management and policy among many countries in support of their health system reform efforts. Healthcare professionals need retooling to provide stewardship to complex new health financing systems. Most health service leaders are mid career professionals and cannot transplant themselves to study on American university campuses. They demand high quality programs, designed to enable most coursework to be completed overseas. Aided by recent distance education technology, the University of South Carolina's Department of Health Services Policy and Management developed and provides doctoral programs for working professionals in Taiwan and South Korea with a minimal and convenient campus attendance requirement. This paper presents the experience of setting up the programs, management, quality control, and benefits for both students overseas and for our Department's mission and on-campus programs. Our experience is that there are many challenges, but it is also rewarding from academic, scholarly, and financial perspectives.
Transparency and quality of financial disclosures. The case of Romanian listed companies*

Full Text Available This paper addresses the transparency and the quality of financial disclosures of listed entities in the case of an emerging economy (i.e. Romania, in order to shed some light on the particular local context of the country and its impact on accounting practices. We analyze the entire population of non-financial entities listed in the first tier of the Bucharest Stock Exchange for the 2012 financial year. We are limited in our research by the size of the sample, which depends, however, on the small size of the Romanian stock market. In order to compensate for the small size of the sample, we assess 50 items related to disclosure, synthesized in two scores, i.e. transparency and quality. Also, we identify some factors associated with disclosure by investigating the correlation with several firm-related factors. Our results reveal a medium level of transparency and quality of Romanian listed companies, with significant variations between firms and between the sub-scores. The most important factors correlated with disclosure are company size and the presence of institutional investors. The results confirm to some extent most of the basic assumptions of the agency theory and also prove the importance of a new variable for emerging econo-mies, specifically the presence of institutional investors *This work was cofinanced from the European Social Fund through Sectoral Operational Programme Human Resources Development 2007-2013, project number POSDRU/159/1.5/S./134197 a Performance and excellence in doctoral and postdoctoral research in Romanian economics science domaina.

With increased cross-border movement, ensuring safe and high-quality healthcare has gained primacy. The purpose of recertification is to ensure quality of care through periodically attesting doctors' professional proficiency in their field. Professional migration and facilitated cross-border recognition of qualifications, however, make us question the fitness of national policies for safeguarding patient care and the international accountability of doctors. We performed document analyses and conducted 19 semistructured interviews to identify and describe key characteristics and effective components of 10 different European recertification systems, each representing one case (collective case study). We subsequently compared these systems to explore similarities and differences in terms of assessment criteria used to determine process quality. Great variety existed between countries in terms and assessment formats used, targeting cognition, competence and performance (Miller's assessment pyramid). Recertification procedures and requirements also varied significantly, ranging from voluntary participation in professional development modules to the mandatory collection of multiple performance data in a competency-based portfolio. Knowledge assessment was fundamental to recertification in most countries. Another difference concerned the stakeholders involved in the recertification process: while some systems exclusively relied on doctors' self-assessment, others involved multiple stakeholders but rarely included patients in assessment of doctors' professional competence. Differences between systems partly reflected different goals and primary purposes of recertification. Recertification systems differ substantially internationally with regard to the criteria they apply to assess doctors' competence, their aims, requirements, assessment formats and patient involvement. In the light of professional mobility and associated demands for accountability, we recommend that
A marketing clinical doctorate programs.
Montoya, Isaac D; Kimball, Olive M
2007-01-01
Over the past decade, clinical doctorate programs in health disciplines have proliferated amid both support and controversy among educators, professional organizations, practitioners, administrators, and third-party payers. Supporters argue that the explosion of new knowledge and increasing sophistication of technology have created a need for advanced practice models to enhance patient care and safety and to reduce costs. Critics argue that necessary technological advances can be incorporated into existing programs and believe that clinical doctorates will increase health care costs, not reduce them. Despite the controversy, many health disciplines have advanced the clinical doctorate (the most recent is the doctor of nursing practice in 2004), with some professions mandating the doctorate as the entry-level degree (i.e., psychology, pharmacy, audiology, and so on). One aspect of the introduction of clinical doctoral degrees has been largely overlooked, and that is the marketing aspect. Because of marketing considerations, some clinical doctorates have been more successfully implemented and accepted than others. Marketing is composed of variables commonly known as "the four P's of marketing": product, price, promotion, and place. This report explores these four P's within the context of clinical doctorates in the health disciplines.
A FRAMEWORK FOR TRANSPARENCY IN INTERNATIONAL TRADE
Directory of Open Access Journals (Sweden)
Bernal Turnes, Paloma
2015-01-01
Full Text Available The aim of this paper is to cover the gap in literature about transparency in the context of international trade facilitation. It focuses on the importance of transparency in achieving growth in international trade and the differences between non-transparent practices and corruption in global trade. Managing the disclosure of information about rules, regulations and laws is not the only trade policy instrument where transparency becomes important. To build a framework on levels of transparency we developed a matrix classifying the transparency of each country based on ease of doing business and levels of bribery. Four different strategies are explained based on the different scenarios of transparency in international trade. The main conclusions reflect that disclosure of information is not enough to guarantee transparency and monitoring of transparency must be improved.
Interventions for improving patients' trust in doctors and groups of doctors.
Rolfe, Alix; Cash-Gibson, Lucinda; Car, Josip; Sheikh, Aziz; McKinstry, Brian
2014-03-04
Trust is a fundamental component of the patient-doctor relationship and is associated with increased satisfaction, adherence to treatment, and continuity of care. Our 2006 review found little evidence that interventions improve patients' trust in their doctor; therefore an updated search was required to find out if there is further evidence of the effects of interventions that may improve trust in doctors or groups of doctors. To update our earlier review assessing the effects of interventions intended to improve patients' trust in doctors or a group of doctors. In 2003 we searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE, EMBASE, Health Star, PsycINFO, CINAHL, LILACS, African Trials Register, African Health Anthology, Dissertation Abstracts International and the bibliographies of studies selected for inclusion. We also contacted researchers active in the field. We updated and re-ran the searches on available original databases (Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library issue 2, 2013), MEDLINE (OvidSP), EMBASE (OvidSP), PsycINFO (OvidSP), CINAHL (Ebsco)) as well as Proquest Dissertations and Current Contents for the period 2003 to 18 March 2013. Randomised controlled trials (RCTs), quasi-randomised controlled trials, controlled before and after studies, and interrupted time series of interventions (informative, educational, behavioural, organisational) directed at doctors or patients (or carers) where trust was assessed as a primary or secondary outcome. Two review authors independently extracted data and assessed the risk of bias of included studies. Where mentioned, we extracted data on adverse effects. We synthesised data narratively. We included 10 randomised controlled trials (including 7 new trials) involving 11,063 patients. These studies were all undertaken in North America, and all but two involved primary care. As expected, there was considerable heterogeneity between
Phenomenal transparency in achromatic checkerboards.
Masin, S C
1999-04-01
The study explored the luminance relations that determine the occurrence of achromatic transparency in phenomenal surfaces on complex backgrounds. Let the luminances of the left and right parts of a transparent surface on a bipartite background and those of the left and right parts of the bipartite background be p and q and m and n, respectively. Metelli proposed that this surface looks transparent when the rule p q if m > n) is satisfied, and Masin and Fukuda that it looks transparent when the inclusion rule is satisfied, that is, when p epsilon (m, q) or q epsilon (p, n). These rules also apply to achromatic checkerboards formed by one checkerboard enclosed in another checkerboard. This study shows that only the inclusion rule correctly predicted the occurrence of transparency in these checkerboards.

Kazarkin, B; Mohammed, A S; Stsiapanau, A; Zhuk, S; Satskevich, Y; Smirnov, A
2014-01-01
We report a transparent conductor based on Al nanomesh, which was fabricated through Al anodization and etching processes. The Al anodization was performed at low temperature condition to slow down the anodization rate to achieve the well-controlled thickness of an Al nanomesh. By careful controlling of the anodization process, we can fabricate Al nanomesh transparent conductors with different sheet resistance and optical transparency in the visible spectrum range. We shall show that Al nanomesh transparent conductor is a strong contender for a transparent conductor dominated by ITO

A method for fabrication of highly transparent platinum counter electrodes (CEs) has been developed based on spray coating of Pt nanoparticles (NPs) on hot substrates. This method leads to 86% reduction in Pt consumption reducing the Pt cost per peak watt of counter electrode from $0.79/Wp down to $0.11/Wp compared to the conventional Pt counter electrodes made by sputter deposition. The simplicity and low cost of this method provide a basis for an up-scalable fabrication process. The Pt NP layer is over 88% transparent, leading to overall transparency of 80% when incorporated with indium tin oxide/glass substrates for functional counter electrodes. This counter electrode exhibits a large surface area and high catalytic activity, comparable to that of the conventional opaque CEs. Semi-transparent dye-sensitized solar cells fabricated based on this counter electrode showed 6.17% power conversion efficiency. - Highlights: • Counter electrode (CE) prepared by spraying nanoparticle (NP) Pt on hot substrate. • Low cost and scalable fabrication process of CE. • The spray deposited CE uses 10 times less Pt compared to the sputtering method. • The CE is 80% transparent and exhibits a large surface and high catalytic activity. • A semitransparent dye-sensitized solar cell with Pt NP CE was 6.17% efficient.

Narrative Transparency: Adopting a Rhetorical Stance
DEFF Research Database (Denmark)
Arnould, Eric; Press, Melea
2014-01-01
In this paper, we look at how alternative marketing organisations communicate transparency in a climate of generalised risk and scepticism. We contrast the traditional numeric approach to transparency, which involves auditing and third-party certifications; with an alternative approach that we call...... narrative transparency. Central to narrative transparency is an emphasis on stake-holder dialogue and an invitation to stake-holders to play the role of auditor. This article illustrates how alternative marketing organisations engage in rhetorical tactics central to a narrative approach, to communicate...... transparency to their stakeholders. These rhetorical tactics include persona, allegory, consumer sovereignty and enlightenment. Community supported agriculture programmes from across the United States are the context for this study. Findings enrich discussions about best practices for transparency...

Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals' websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors' ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal's impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals.
Transparency, price-dependent demand and product variety

This paper revisits the relationship between transparency on the consumer side and product variety as analyzed in Schultz (2009). We identify two welfare effects of transparency. More transparency decreases price-cost margins which is beneficial forwelfare. On the other hand, more transparency reduces variety which can be positive or negative for welfare. Overall, more transparency is always welfareimproving.
Robot transparency, trust and utility
Wortham, Robert H.; Theodorou, Andreas
2017-07-01
As robot reasoning becomes more complex, debugging becomes increasingly hard based solely on observable behaviour, even for robot designers and technical specialists. Similarly, non-specialist users have difficulty creating useful mental models of robot reasoning from observations of robot behaviour. The EPSRC Principles of Robotics mandate that our artefacts should be transparent, but what does this mean in practice, and how does transparency affect both trust and utility? We investigate this relationship in the literature and find it to be complex, particularly in nonindustrial environments where, depending on the application and purpose of the robot, transparency may have a wider range of effects on trust and utility. We outline our programme of research to support our assertion that it is nevertheless possible to create transparent agents that are emotionally engaging despite having a transparent machine nature.
Transparency in high-energy nuclear collisions

Karol, P.J.
1992-01-01
Problems associated with transparency schemes based on sharp cutoff models are discussed. The soft spheres model of hadron-nucleus and nucleus-nucleus collisions has been used to explore the influence of the realistic nuclear density geometry on transparency. An average nuclear transparency and an average reaction transparency are defined and their dependence on target and projectile dimensions and on the hadron-nucleon collision cross section are described. The results are expected to be valid for projectile energies above several hundred MeV/nucleon through the ultrarelativistic regime. For uniform (hard sphere) nuclear profiles, methods for obtaining effective total transparencies are suggested

Intolerance and Violence Against Doctors.
Singh, Meharban
2017-10-01
Intolerance and grouse against doctors is a global phenomenon but India seems to lead the world in violence against doctors. According to World Health Organization, about 8-38% healthcare workers suffer physical violence at some point in their careers. Many more are verbally abused or threatened. Public is almost behaving like health sector terrorists. The spate of increasing attacks on doctors by damaging their property and causing physical injury is not acceptable by any civilized society. The public is becoming increasingly intolerant to a large number of social issues because of poor governance and vote bank politics. There is a need to arrest the development of further distrust between doctors and their patients/relatives, otherwise it will compromise all achievements of medical science and adversely affect healing capabilities of doctors. Rude and aggressive behavior of the patients or their family members, and arrogant and lackadaisical approach of the doctor, adversely affects the doctor-patient relationship and the outcome of the patient. The doctors, hospital administration and government must exercise "zero tolerance" with respect to acts of violence against healthcare professionals. It is possible to reduce the incidence of intolerance against doctors but difficult to eliminate it completely. The healthcare providers should demonstrate greater compassion and empathy with improved communication skills. The hospitals must have adequate infrastructure, facilities and staff to handle emergencies without delay and with due confidence and skills. The security of healthcare providers, especially in sensitive areas, should be improved by having adequate number of security guards, frisking facilities, extensive CCTV network and availability of "Quick response team" to handle unruly mob. In case of any grievances for alleged mismanagement, the public should handle the situation in a civilized manner and seek redressal through Medical Protection Act and legal

China has the largest number of type 2 diabetes mellitus (T2DM) cases globally and individuals with T2DM have an increased risk of developing mental health disorders and functional problems. Despite guidelines recommending that psychological care be delivered in conjunction with standard T2DM care; psychological care is not routinely delivered in China. Community Health Centre (CHC) doctors play a key role in the management of patients with T2DM in China. Understanding the behavioural determinants of CHC doctors in the implementation of psychological care recommendations allows for the design of targeted and culturally appropriate interventions. As such, this study aimed to examine barriers and enablers to the delivery of psychological care to patients with T2DM from the perspective of CHC doctors in China. Two focus groups were conducted with 23 CHC doctors from Shenzhen, China. The discussion guide applied the Theoretical Domains Framework (TDF) that examines current practice and identifies key barriers and enablers perceived to influence practice. Focus groups were conducted with an interpreter, and were digitally recorded and transcribed. Two researchers independently coded transcripts into pre-defined themes using deductive thematic analysis. Barriers and enablers perceived by doctors as being relevant to the delivery of psychological care for patients with T2DM were primarily categorised within eight TDF domains. Key barriers included: CHC doctors' knowledge and skills; time constraints; and absence of financial incentives. Other barriers included: societal perception that treating psychological aspects of health is less important than physical health; lack of opinion leaders; doctors' intentional disregard of psychological care; and doubts regarding the efficacy of psychological care. In contrast, perceived enablers included: training of CHC doctors in psychological skills; identification of afternoon/evening clinic times when recommendations could be
Skill set development of doctoral and post-doctoral graduates in life sciences.

Doctoral and post-doctoral training programs at leading research universities in the USA are highly important in generating the much needed knowledge in science, technology, engineering, and mathematics for keeping rural and urban economies strong and societies healthy and prosperous. In addition, innovative graduate and post doctoral research programs are the driving engines of the success of U.S. economy and have made the U.S. the most successful model of generating new knowledge in the broader areas of life sciences (and agricultural education, research, and extension). We need to do everything in our power to make these training programs innovative, collaborative, independent, and resourceful so that students are trained in different disciplines making them more flexible within a range of challenges and opportunities. The training programs must empower students to solve complex and interdisciplinary problems of the society in 21st century and make our students competitive within a global economic system, to improve the health of the nation's economy. If our land grant schools and institutions of higher learning are not preparing doctoral students to be globally competitive scientists to create new knowledge and technologies to solve complex and interdisciplinary problems of the 21st century, then either we need to redefine the mission of our land grant system or we risk losing our role to serve the public and industry effectively. Doctoral and post doctoral students should be given the needed skills and experiences to prepare them for tenure track faculty jobs at leading US Universities in the 21st century as well as prepare them for the world outside of academia. I would say minimum competency skills are needed as "bare survival skills" for all doctoral students to become successful after obtaining PhD degrees. Today's PhD students will be working in a global but highly competitive, rapidly changing, and complex world. It is no longer enough to be a good

With significant impacts of carbon dioxide on global climate change, carbon dioxide sensing is of great importance. However, most of the existing sensing technologies are prone to interferences from carbon monoxide, or suffer from the use of sophisticated instruments. This research reports the development of reproducible carbon dioxide sensor using roll-to-roll compatible doctor blade coated three-dimensional macroporous photonic crystals. The pores are functionalized with amine groups to allow the reaction with carbon dioxide in the presence of humidity. The adsorption of carbon dioxide leads to red-shift and amplitude reduction of the optical stop bands, resulting in carbon dioxide detection with visible readout. The dependences of the diffraction wavelength on carbon dioxide partial pressure for various amine-functionalized photonic crystals and different humidities in the environment are systematically investigated. In addition, the reproducibility of carbon dioxide sensing has also been demonstrated in this research. Copyright © 2017 Elsevier Inc. All rights reserved.
Transparent CuInS2/PMMA nanocomposites luminescent in the visible and NIR region
International Nuclear Information System (INIS)
Gugula, Krzysztof; Bredol, Michael
2014-01-01
Nanocomposites combining functional nanoparticles and transparent polymers allow for stabilization of filler properties over long periods of time while retaining transparency of the polymer matrix. Here we employ CuInS 2 /ZnS quantum dots (QDs), ternary visible- and NIR-emitting semiconductors as wavelength-tunable luminescent fillers. Luminescence in the near infrared (NIR) is of particular interest in medicine which allows deep penetration into human tissue enabling in vivo diagnostics and treatment, while visible emitters may serve as color converters in displays or lighting. To stabilize the optical properties of QDs and prevent agglomeration, polymethyl metacrylate (PMMA) was chosen as a matrix. These novel polymer nanocomposites (PNCs) show good optical properties and stability under ambient conditions, and can be easily deposited over large areas. High-quality QDs and hydrophobic functionalization with long-chain hydrocarbons are a prerequisite for embedding into a PMMA matrix. Transparent PNC films without visible scattering losses were obtained for 1 wt-% QD loading with respect to the polymer. Partial transparency is retained up to 10 wt-% QD loading and vanishes rapidly at higher loading. Luminescence properties increase up to 5 wt-% and then decrease rapidly due to QD agglomeration and reabsorption between adjacent particles. Potential applications include converter materials for medical applications, laser layers, displays and white LEDs. (orig.)

On China's energy intensity statistics: Toward a comprehensive and transparent indicator
International Nuclear Information System (INIS)
Wang Xin
2011-01-01
A transparent and comprehensive statistical system in China would provide an important basis for enabling a better understanding of the country. This paper focuses on energy intensity (EI), which is one of the most important indicators of China. It firstly reviews China's GDP and energy statistics, showing that China has made great improvements in recent years. The means by which EI data are released and adjusted are then explained. It shows that EI data releases do not provide complete data for calculating EI and constant GDP, which may reduce policy transparency and comprehensiveness. This paper then conducts an EI calculation method that is based on official sources and that respects the data availability of different data release times. It finds that, in general, China's EI statistics can be considered as reliable because most of the results generated by author's calculations match the figures in the official releases. However, two data biases were identified, which may necessitate supplementary information on related constant GDP values used in the official calculation of EI data. The paper concludes by proposing short- and long-term measures for improving EI statistics to provide a transparent and comprehensive EI indicator. - Highlights: → This paper examines data release and adjustment process of energy intensity (EI) target of China. → New insights on the comprehensiveness and transparency of EI data. → Potential data bias between author's calculation and official data due to lack of constant GDP data. → Proposition for improving short- and long-term EI statistical works.

Can transparency be measured - a look ahead
International Nuclear Information System (INIS)
Jorle, A.
2007-01-01
The simple answer to this question is no. But if you define the expression and decide transparency actually is, the answer might be different. Transparency means different things in different places. In one country transparency meant almost total access to anything that a government authority has in its possession. In another country transparency is more strict access to certain decisions, decisions makers or documents written with the sole purpose of informing the public. What variables could be found in the word transparent, what is a transparent regulator? In this short presentation we will deal with some important settings or fundamental prerequisites for a regulator calling itself transparent. Perhaps we should look at them in order of importance. Some days it is difficult to do all at once. As a final point, if we as regulators wish to call ourselves transparent in a future with diminishing national borders, fast electronic communication and increasing world wide media impact, what does the world require from us as regulators?

Australian doctors and the visual arts. Part 1. Doctor-artists in New South Wales.
Hamilton, D G
Since Europeans first settled in Australia their doctors have been interested in the visual arts. Some have been hobby painters and sculptors, a few with great distinction. Some have been gallery supporters and administrators. A few have written art books. Some have been outstanding photographers. Of the larger number of doctors who have collected art, only those are mentioned who have made their collections public or have made important donations to galleries. The subject of Australian doctors and the visual arts will be discussed in six articles in this and following issues of the journal. The first deals with doctor-artists in New South Wales.

Full Text Available The article discusses an essay collection by Marek Bieńczyk, Przeźroczystość [Transparency]. The concept, placed in various context, shows various aspects and is seen in various shades. The author does not put forward a statement, but rather proposes a work to be done: to determine the modality of transparency. The concept initially seems to be mainly epistemological: the cognizant subject would like to make the world transparent, to discover all possible mysteries. Before that, however, the subject must know itself, and here the dream of transparency also plays the key role. Lack of epistemological transparency is the main cause of melancholy and its reverse — hysteria. The concept turns out to be important in the domain of love — the loer thinks that (she knows the desired person more better anybody else, that (she has entirely penetrated the subjectivity of the Other. Ultimately, however, the dream of transparency goes down to a slow demise of the subject: as self-discovery progresses, there is less and less of the discoverer. In conclusion of this work, the border of modality of the concept turns out to be horrifyingly obvious. The desire for transparency consequently searches not for knowledge, but for an escape whose name is death.

who 'all students' refers to and what science literacy means for learners with diverse cultural, linguistic or economic backgrounds. Faculty members' views significantly influence the nature and content of the courses as well as the program focus. It was also shown that a relationship exists between faculty views and the views of their doctoral students and recent graduates. In general, faculty exhibited narrower and more in-depth views about issues they consider being important in the field of science education, than doctoral students and recent graduates. External funding is critical in doctoral studies as it enables faculty to enact their visions of achieving science literacy for all. The study provides some implications for practice, policy and research. In order to achieve both equity and excellence in science teaching, there is need for dialogue among science educators to enable them to address issues of equity more effectively than at present. If doctoral programs are to continue preparing graduates who can address important issues in the field, there is need for external funding for specific research programs.

Healthy Doctors – Sick Medicine

Full Text Available Doctors are among the healthiest segments of the population in western countries. Nevertheless, they complain strongly of stress and burnout. Their own explanation is deprofessionalisation: The honourable art of doctoring has been replaced by standardised interventions and production lines; professional autonomy has withered. This view is shared by many medical sociologists who have identified a “golden age of medicine,” or “golden age of doctoring,” starting after World War II and declining around 1970. This article looks at some of the central sociological literature on deprofessionalisation, particularly in a perspective of countervailing powers. It also looks into another rise-and-fall model, proposed by the medical profession itself, where the fall in professional power was generated by the notion that there are no more white spots to explore on the map of medicine. Contemporary doctoring is a case of cognitive dissonance, where the traditional doctor role seems incompatible with modern health care.Keywords: deprofessionalisation, professional autonomy, cognitive dissonance, golden age of doctoring

Since the time of Web 2.0, more and more consumers have used online doctor reviews to rate their doctors or to look for a doctor. This phenomenon has received health care researchers' attention worldwide, and many studies have been conducted on online doctor reviews in the United States and Europe. But no study has yet been done in China. Also, in China, without a mature primary care physician recommendation system, more and more Chinese consumers seek online doctor reviews to look for a good doctor for their health care concerns. This study sought to examine the online doctor review practice in China, including addressing the following questions: (1) How many doctors and specialty areas are available for online review? (2) How many online reviews are there on those doctors? (3) What specialty area doctors are more likely to be reviewed or receive more reviews? (4) Are those reviews positive or negative? This study explores an empirical dataset from Good Doctor website, haodf.com—the earliest and largest online doctor review and online health care community website in China—from 2006 to 2014, to examine the stated research questions by using descriptive statistics, binary logistic regression, and multivariate linear regression. The dataset from the Good Doctor website contained 314,624 doctors across China and among them, 112,873 doctors received 731,543 quantitative reviews and 772,979 qualitative reviews as of April 11, 2014. On average, 37% of the doctors had been reviewed on the Good Doctor website. Gynecology-obstetrics-pediatrics doctors were most likely to be reviewed, with an odds ratio (OR) of 1.497 (95% CI 1.461-1.535), and internal medicine doctors were less likely to be reviewed, with an OR of 0.94 (95% CI 0.921-0.960), relative to the combined small specialty areas. Both traditional Chinese medicine doctors and surgeons were more likely to be reviewed than the combined small specialty areas, with an OR of 1.483 (95% CI 1.442-1.525) and an OR of 1

Graphical abstract: - Highlights: • Transparent self-supported latex films were fabricated by a peel-off process. • Various template substrates were used for creating e.g. hierarchically structured latex films. • Ultra-thin and semi-transparent conductive gold electrodes were evaporated on the latex films.Electrochemical experiments were carried out to verify the applicability of the electrodes. - Abstract: Different length scale alterations in topography, surface texture, and symmetry are known to evoke diverse cell behavior, including adhesion, orientation, motility, cytoskeletal condensation, and modulation of intracellular signaling pathways. In this work, self-supported latex films with well-defined isotropic/anisotropic surface features and hierarchical morphologies were fabricated by a peel-off process from different template surfaces. In addition, the latex films were used as substrates for evaporated ultrathin gold films with nominal thicknesses of 10 and 20 nm. Optical properties and topography of the samples were characterized using UV–vis spectroscopy and Atomic Force Microscopy (AFM) measurements, respectively. The latex films showed high-level transmittance of visible light, enabling the fabrication of semi-transparent gold electrodes. Electrochemical impedance spectroscopy (EIS) measurements were carried out for a number of days to investigate the long-term stability of the electrodes. The effect of 1-octadecanethiol (ODT) and HS(CH_2)_1_1OH (MuOH) thiolation and protein (human serum albumin, HSA) adsorption on the impedance and capacitance was studied. In addition, cyclic voltammetry (CV) measurements were carried out to determine active medicinal components, i.e., caffeic acid with interesting biological activities and poorly water-soluble anti-inflammatory drug, piroxicam. The results show that the fabrication procedure presented in this study enables the formation of platforms with hierarchical morphologies for multimodal (optical and

To determine the percentage of medical teachers and fresh doctors who feel that graduating doctors are competent or incompetent to handle common ailments and to evaluate the reasons for their perceptions. Sequential mixed method. First phase extending from December 2010 to December 2011 and second phase was conducted in March 2014. First phase comprised electronic distribution of questionnaire to 100 medical teachers and fresh doctors working in hospitals attached with 5 private and 5 public sector medical colleges of Lahore and Karachi to rate an average house officer on a frequency scale of 1 - 6 and do self-assessment, in case of a fresh doctor. The second phase included interviews of 20 medical teachers to explore justification for their rating in the survey questionnaire and for triangulation of data. Quantitative data was analyzed through SPSS version 15 to calculate frequencies and percentages and interviews were analyzed through quasi-statistical approach. In survey, 38.36% out of 73 medical teachers and 30% out of 20 medical teachers in interviews confirmed their confidence on consulting fresh doctors for common ailments as opposed to 61.64% and 70% respectively, expressing their dissatisfaction. Self-assessment of fresh doctors indicated that 40% are confident in handling common medical conditions as opposed to 33.3% out of 75 respondents, who are not confident about their clinical skills. Faculty and self-assessment of fresh doctors has a fair overlap, indicating room for further improvement in the house job training program.

Full Text Available The transparency of governance is not only a necessary and sufficient condition for bringing about accountability, but also the basis for the possibility of democracy in the global sphere. Although there is no automatic progress from transparency to democratic global governance, this principle helps to create more democratic, open and fair societies. Recently, the importance of inclusiveness, transparency and procedural safeguards has emerged as a critical theme. The practical implementation of fair global governance mechanisms, procedures, and institutions will always depend on the level of participation, contestation, or solidarity among the different stakeholders represented at the local, national or international level. Recent years have clearly shown a trend towards increasing transparency and inclusiveness in international organizations’ activities and operations, in contrast to opaqueness or lack of transparency which was a very common practice in diplomacy during past centuries. The inclusion of transparency and inclusiveness elements in the decision-making rules of an international organization are fundamental for these norms to be considered not only ‘more legal,’ but also to have a higher level of legitimacy. The General Assembly decided in its Resolution 60/251 of 2006 that the methods of work of the Human Rights Council should be transparent, fair and impartial and should enable genuine dialogue. Finally, the role played by the BRICS countries at the Security Council and the Human Rights Council is critical in regards to its working methods.

To report a qualitative study of themes doctors raised spontaneously, in a large-scale prospective cohort study covering many aspects of their medical careers, when referring to their own chronic illness or disability. Questionnaire survey. UK. Questionnaires were sent one, five and 10 years after graduation to 44,539 doctors who qualified between 1993 and 2012 in the UK: 38,613 questionnaires were returned and 11,859 respondents provided comments made by doctors about their training or work. The comments of 123 doctors about their own chronic illness or disability. Main themes raised included poor support for doctors with chronic illness or disability, delays in and changes to careers (either planned ahead or imposed), the impact of pressure at work, difficulties returning to work after illness, limitations on career choices and inadequate careers advice for doctors with chronic illness or disabilities. More needs to be done to ensure that doctors with chronic illness or disability receive appropriate support. Occupational health guidance should be monitored closely, with more support for ill doctors including adjustments to the job, help if needed with morale and mental health, and advice on career options. Further studies should establish the prevalence of long-term health conditions among doctors.

Through a glass darkly - the meaning of transparency
International Nuclear Information System (INIS)
Loy, J.
2007-01-01
The paper first discusses the word 'transparency'. It is a metaphor drawn from optics; it is a term used in social and political science; the international civil society organisation. 'Transparency International' sees it as the paradigm to fight corruption in the world. From this discussion, the paper offers a working definition applicable to a nuclear regulatory organisation. The paper describes a difference between having transparent process, which might be called passive transparency; and transparent engagement with stakeholders -- active transparency. It discusses some of the issues and problems that arise for a nuclear regulatory organisation seeking to operate transparently. Much of the difficulty with true transparency is that it reveals the 'untidiness' of life. 'We see now as through a glass darkly'. What is the general view of society and the cultural attitudes towards Government agencies revealing that they are not perfect'? Can you have a transparent nuclear regulator of a secretive industry and with other stakeholders having political agendas? How can a technical 'judgment call' ever be fully transparent? Can an active culture of transparency sometimes result in a mere public relations campaign? Can transparency in a nuclear regulatory create expectations amongst stakeholders that will prove impossible to meet? These questions are discussed with some real-life examples. The paper concludes with some suggested 'fundamentals' for transparency in nuclear regulatory organisations. (author)

We report a study on transparent organic light-emitting diodes (OLEDs) with different bi-directional emission colors, enabled by color-conversion organic capping layers. Starting from a transparent blue OLED with an uncapped Ag top electrode exhibiting an average transmittance of 33.9%, a 4-(dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM)-doped tris-(8-hydroxy-quinolinato)-aluminum (Alq3) capping layer is applied to achieve color-conversion from blue to orange-red on the top side while maintaining almost unchanged device transmittance. This color-conversion capping layer does not only change the color of the top side emission, but also enhances the overall device efficiency due to the optical interaction of the capping layer with the primary blue transparent OLED. Top white emission from the transparent bi-directional OLED exhibits a correlated color temperature around 6000–7000 K, with excellent color stability as evidenced by an extremely small variation in color coordinate of Δ(x,y)=(0.002, 0.002) in the forward luminance range of 100–1000 cd m{sup −2}. At the same time, the blue emission color of bottom side is not influenced by the color conversion capping layer, which finally results in different emission colors of the two opposite sides of our transparent OLEDs. - Highlights: • We report transparent organic light-emitting diodes (OLEDs) with different bi-directional emission colors. • Transparent blue OLED with color-conversion organic capping layers (CCL) shows orange top side emission. • Top white emission exhibits a CCT around 7000 K, with excellent color stability on a driving voltage.

Full Text Available We deposited transparent ferroelectric lead zirconate titanate thin films on fused silica and contacted them via Al-doped zinc oxide (AZO transparent electrodes with an interdigitated electrode (IDE design. These layers, together with a TiO2 buffer layer on the fused silica substrate, are highly transparent (>60% in the visible optical range. Fully crystallized Pb(Zr0.52Ti0.48O3 (PZT films are dielectrically functional and exhibit a typical ferroelectric polarization loop with a remanent polarization of 15 μC/cm2. The permittivity value of 650, obtained with IDE AZO electrodes is equivalent to the one measured with Pt electrodes patterned with the same design, which proves the high quality of the developed transparent structures.
Transmission in Optically Transparent Core Networks

Call for Papers: Transmission in Optically Transparent Core Networks Guest Feature Editors Dan Kilper and Rich Jensen, Coordinating Associate Editors Klaus Petermann and Miroslav Karasek, Guest Feature Editors Submission deadline: 15 June 2007 Optically transparent networks in which optical transport signals are routed uninterrupted through multiple nodes have long been viewed as an important evolutionary step in fiber optic communications. More than a decade of research and development on transparent network technologies together with the requisite traffic growth has culminated in the recent deployment of commercial optically transparent systems. Although many of the traditional research goals of optical transmission remain important, optical transparency introduces new challenges. Greater emphasis is placed on system efficiency and control. The goal of minimizing signal terminations, which has been pursued through increasing reach and channel capacity, also can be realized through wavelength routing techniques. Rather than bounding system operation by rigid engineering rules, the physical layer is controlled and managed by automation tools. Many static signal impairments become dynamic due to network reconfiguration and transient fault events. Recently new directions in transmission research have emerged to address transparent networking problems. This special issue of the Journal of Optical Networking will examine the technologies and theory underpinning transmission in optically transparent core networks, including both metropolitan and long haul systems. Scope of Submission The special issue editors are soliciting high-quality original research papers related to transmission in optically transparent core networks.

Does transparent government agencies strengthen trust?
Grimmelikhuijsen, S.G.

Exploring Quantitative Framework to Evaluate Nuclear Transparency
International Nuclear Information System (INIS)
Ha, Jeemin; Yim, Mansung; Park, Hyeon Seok
2014-01-01
In this work, a definition of nuclear transparency is elaborated and ways to represent a country's nuclear transparency are examined. For evaluating nuclear transparency, it is necessary to define three elements first; an information seeker who wants to see, an information seek whom an information seeker wants to see, and information related to nuclear materials and activities. The States with high capacity of civilian nuclear power had a tendency to follow IAEA safeguards agreements well. And it means that their levels of the transparency are relatively high. Besides, the data of international assurances is one of the good indicators to confirm States' transparency. The current study explored the use of two measures, IAEA safeguards and voluntary reporting as a way to represent nuclear transparency. Using these measures seemed to agree with the notion that nuclear transparency is important in the success of civilian nuclear power development

Full Text Available This article examines the efforts and achievements of Oen Boen Ing, a Tionghoa doctor, to improve the quality of health of the poorer inhabitants of Surakarta. Dr Oen played an important role in five different periods: Dutch colonialism, the Japanese occupation, the Indonesian revolution, Soekarno’s regime, and Suharto’s New Order. Known for being a benevolent doctor, activist, and patriot of the revolution during his life-time, Dr Oen also gave medical assistance to the needy, which famously earned him the accolade of “doctor of the poor”. During the Indonesian revolution, Dr Oen assisted the Student Soldiers (Tentara Pelajar and afterwards was appointed the member of Supreme Advisory Council (Dewan Pertimbangan Agung/DPA by Soekarno in 1949. As a benevolent doctor and activist, Dr Oen is remembered for founding the Panti Kosala Hospital which was renamed to perpetuate his name on 30 October 1983, exactly a year after his passing. When he died, thousands of peoples gathered to pay their final respects to the doctor. He was honoured with a ceremony conducted in the Mangkunegaran Palace. Dr Oen’s name will be eternally respected, especially in Surakarta.

Blockchain protocols in clinical trials: Transparency and traceability of consent
Benchoufi, Mehdi; Porcher, Raphael; Ravaud, Philippe
2018-01-01
Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders. Our goal is to implement a process allowing for collection of patients’ informed consent, which is bound to protocol revisions, storing and tracking the consent in a secure, unfalsifiable and publicly verifiable way, and enabling the sharing of this information in real time. For that, we build a consent workflow using a trending technology called Blockchain. This is a distributed technology that brings a built-in layer of transparency and traceability. From a more general and prospective point of view, we believe Blockchain technology brings a paradigmatical shift to the entire clinical research field. We designed a Proof-of-Concept protocol consisting of time-stamping each step of the patient’s consent collection using Blockchain, thus archiving and historicising the consent through cryptographic validation in a securely unfalsifiable and transparent way. For each protocol revision, consent was sought again. We obtained a single document, in an open format, that accounted for the whole consent collection process: a time-stamped consent status regarding each version of the protocol. This document cannot be corrupted and can be checked on any dedicated public website. It should be considered a robust proof of data. However, in a live clinical trial, the authentication system should be strengthened to remove the need for third parties, here trial stakeholders, and give participative control to the peer users. In the future, the complex data flow of a clinical trial could be tracked by using Blockchain, which core functionality, named Smart Contract, could help prevent clinical trial events not occurring in the correct chronological order, for example including patients before they consented or analysing case report form data before freezing the database. Globally, Blockchain could help with reliability, security, transparency and could be

Lines that induce phenomenal transparency.
Grieco, Alba; Roncato, Sergio
2005-01-01
Three neighbouring opaque surfaces may appear split into two layers, one transparent and one opaque beneath, if an outline contour is drawn that encompasses two of them. The phenomenon was originally observed by Kanizsa [1955 Rivista di Psicologia 69 3-19; 1979 Organization in Vision: Essays on Gestalt Psychology (New York: Praeger)], for the case where an outline contour is drawn to encompass one of the two parts of a bicoloured figure and a portion of a background of lightest (or darkest) luminance. Preliminary observations revealed that the outline contour yields different effects: in addition to the stratification into layers described by Kanizsa, a second split, opposite in depth order, may occur when the outline contour is close in luminance to one of the three surfaces. An initial experiment was designed to investigate what conditions give rise to the two phenomenal transparencies: this led to the conclusion that an outline contour superimposed on an opaque surface causes this surface to emerge as a transparent layer when the luminances of the contour and the surface differ, in absolute value, by no more than 13.2 cd m(-2). We have named this phenomenon 'transparency of the intercepted surface', to distinguish it from the phenomenal transparency arising when the contour and surface are very different in luminance. When such a difference exists, the contour acts as a factor of surface definition and grouping: the portion of the homogeneous surface it bounds emerges as a fourth surface and groups with a nearby surface if there is one close in luminance. The transparency phenomena ('transparency of the contoured surface') perceived in this context conform to the constraints of Metelli's model, as demonstrated by a second experiment, designed to gather 'opacity' ratings of stimuli. The observer judgments conformed to the values predicted by Metelli's formula for perceived degree of transparency, alpha. The role of the outline contour in conveying figural and

Social influence and payoff transparency interact with each other to influence decision making. Social influence masks payoff transparency, and lacking transparency drives people to seek social influence. Moreover, our survey supports our claim by showing that social influence and payoff transparency correlate with each other (r(53) = -.71). Bentley et al.'s model can be revised to accommodate the covariance.
THERMAL PROPERTIES OF TRANSPARENT BARRIER MODIFIED WITH ORGANIC PCMS

Full Text Available Renewable energy sources are increasingly often applied in civil engineering as a mean to reduce buildings energy demand for heating. One of the ways to reduce HVAC energy demand is to limit heat transfer and excessive solar gain through building's glazed barriers. Preliminary results of the research conducted on organic PCM-modified transparent barrier are presented in this paper. Multiple publications concerning PCMs application in structural materials have recently appeared. Most of them are focused on modification of structure of non-transparent sections of buildings' envelope. Augmenting a glazed barrier with PCMs increases its heat capacity and thermal resistance. The most important feature of the assembly is the thermal buffer, a product of PCM's considerable value of specific latent heat. Research were conducted on a triple-pane transparent rectangular barrier, that constituted one of the faces of cubic chamber. Internal volume of the chamber was 1m3. The applied PCM was a mixture of saturated and non-saturated hydrocarbons. The described assembly was subjected to temperature and radiation that occur in Poland during winter. Glazing temperature, melted/total PCM ratio were measured, as well as energy demand for keeping internal temperature at constant level. Measurements were made in steady states, for various PCM layer thickness. The influence of the modification on energy demand was determined, along with the most effective and rational thickness of PCM layer to be applied. Conducted research enabled to develop a basis for further investigation of PCMs application in civil engineering.
Laboratory test result interpretation for primary care doctors in South Africa
Directory of Open Access Journals (Sweden)
Naadira Vanker
2017-03-01
Full Text Available Background: Challenges and uncertainties with test result interpretation can lead to diagnostic errors. Primary care doctors are at a higher risk than specialists of making these errors, due to the range in complexity and severity of conditions that they encounter. Objectives: This study aimed to investigate the challenges that primary care doctors face with test result interpretation, and to identify potential countermeasures to address these. Methods: A survey was sent out to 7800 primary care doctors in South Africa. Questionnaire themes included doctors’ uncertainty with interpreting test results, mechanisms used to overcome this uncertainty, challenges with appropriate result interpretation, and perceived solutions for interpreting results. Results: Of the 552 responses received, the prevalence of challenges with result interpretation was estimated in an average of 17% of diagnostic encounters. The most commonly-reported challenges were not receiving test results in a timely manner (51% of respondents and previous results not being easily available (37%. When faced with diagnostic uncertainty, 84% of respondents would either follow-up and reassess the patient or discuss the case with a specialist, and 67% would contact a laboratory professional. The most useful test utilisation enablers were found to be: interpretive comments (78% of respondents, published guidelines (74%, and a dedicated laboratory phone line (72%. Conclusion: Primary care doctors acknowledge uncertainty with test result interpretation. Potential countermeasures include the addition of patient-specific interpretive comments, the availability of guidelines or algorithms, and a dedicated laboratory phone line. The benefit of enhanced test result interpretation would reduce diagnostic error rates.

We describe the formation and properties of atomically bonded, optical quality, nanostructured thin glass film coatings on glass plates, utilizing phase separation by spinodal decomposition in a sodium borosilicate glass system. Following deposition via magnetron sputtering, thermal processing and differential etching, these coatings are structurally superhydrophilic (i.e., display anti-fogging functionality) and demonstrate robust mechanical properties and superior abrasion resistance. After appropriate chemical surface modification, the surfaces display a stable, non-wetting Cassie-Baxter state and exhibit exceptional superhydrophobic performance, with water droplet contact angles as large as 172°. As an added benefit, in both superhydrophobic and superhydrophilic states these nanostructured surfaces can block ultraviolet radiation and can be engineered to be anti-reflective with broadband and omnidirectional transparency. Thus, the present approach could be tailored toward distinct coatings for numerous markets, such as residential windows, windshields, specialty optics, goggles, electronic and photovoltaic cover glasses, and optical components used throughout the US military.

The aim of this study is to investigate how doctor-consumer interaction in social media influences consumers' health information seeking and usage intention. Based on professional-client interaction theory and expectation confirmation theory, we propose that doctor-consumer interaction can be divided into instrumental interaction and affective interaction. These two types of interaction influence consumers' health information seeking and usage intention through consumer satisfaction and trust towards doctors. To validate our proposed research model, we employed the survey method. The measurement instruments for all constructs were developed based on previous literatures, and 352 valid answers were collected by using these instruments. Our results reveal that consumers' intention to seek health information significantly predicts their intention to use health information from social media. Meanwhile, both consumer satisfaction and trust towards doctors influences consumers' health information seeking and usage intention significantly. With regards to the impact of the interaction between doctors and consumers, the results show that both types of doctor-consumer interaction significantly affect consumer satisfaction and trust towards doctors. The mediation analysis confirms the mediation role of consumer satisfaction and trust towards doctors. Compared with many intentional intervention programs, doctor-consumer interaction can be treated as an effective intervention with low cost to promote consumers' health information seeking and usage. Meanwhile, both instrumental and affective interaction should be highlighted for the best interaction results. At last, consumer satisfaction and trust towards doctors could be considered as the important working mechanisms for the effect of doctor-consumer interaction. Copyright © 2018 Elsevier B.V.

To examine possible risk factors for the doctor to be killed by the patient in the clinical practice by examining a series of murders that involved physicians. This aim has been achieved through a retrospective review on clinical cases of doctors killed by patients within the period between 1988 and 2013, in Italy. In this period 18 Italian doctors have been killed in the workplace, with a rate of 0.3/100,000. In 7 cases, the murder resulted in the context of doctor-dissatisfaction; in 7 cases the murder was committed by a psychiatric patient; 1 case in the context of a stalking; 3 cases occurred in a workplace which was not safe enough. Four categories of at-risk contexts have been identified. One category includes a murder in the context of a doctor-dissatisfaction, perceived by patient. The second category concerns murders committed by patients suffering from mental illness. A third category includes homicides in a workplace which is not safe. The last category comprises the murder in the context of stalking. These categories identify specific dangerous situations for physicians, in which are highlighted elements that have played a crucial role in the murder and for which special precautions are suggested preventive.

Driven by the prospect of rapid economic growth and the perceived need for energy security, the Asia-Pacific region is destined to increase its nuclear energy use in the coming decades. This projected increase, however, will bring with it nuclear proliferation concerns, fueling fears about the security of nuclear material and creating suspicions about its use. The increasing use of nuclear energy inevitably necessitates supplementary efforts, designed to ensure nuclear security and a legitimate use of nuclear energy, other than the obligation to the Treaty on the Nonproliferation of Nuclear Weapons (NPT). Nuclear transparency measures could be useful tools for building confidence that the increasing nuclear energy use does not contribute to nuclear proliferation. These measures could also foster a cooperative tradition that can address rising concerns over nuclear trafficking and terrorism, which require regional coordination to combat. However, moderate progress in implementing transparency measures suggests a lack of political appreciation of this concept. Thus, this paper describes various forms of potential transparency measures to expand the possibilities of the transparency concept and explore areas in which this concept might be applicable. This paper also clarifies some challenges involving transparency projects, and suggests possible ways to address these challenges. (author)

Full Text Available Transparency: Bacen versus BoE. The aim of this paper is to compare the degree of transparency of the Brazilian Central Bank (Bacen with the one verified in the Bank of England (BoE. In order to accomplish this objective, an indicator of transparency is built based on the information that each central bank provides to the public about its monetary policy, its expectation about the future of the economy, its intervention in the financial market, and if there are clear limits and restrictions to the release of information to the general public. The analysis suggests that the Bacen is less transparent and has a less individualistic Monetary Policy Committee in comparison with the BoE. Moreover, it indicates some procedures that could be adopted by the Bacen in order to make its monetary policy more transparent.

BACKGROUND: Hospital doctors face significant challenges in the current health care environment, working with staff shortages and cutbacks to health care expenditure, alongside increased demand for health care and increased public expectations. OBJECTIVE: This article analyses challenges faced by junior hospital doctors, providing insight into the experiences of these frontline staff in delivering health services in recessionary times. DESIGN: A qualitative methodology was chosen. METHODS: Semi-structured in-depth interviews were conducted with 20 doctors from urban Irish hospitals. Interviews were recorded via note taking. Full transcripts were analysed thematically using NVivo software. RESULTS: Dominant themes included the following: (1) unrealistic workloads: characterised by staff shortages, extended working hours, irregular and frequently interrupted breaks; (2) fatigue and its impact: the quality of care provided to patients while doctors were sleep-deprived was questioned; however, little reflection was given to any impact this may have had on junior doctors own health; (3) undervalued and disillusioned: insufficient training, intensive workloads and a perceived lack of power to influence change resulted in a sense of detachment among junior doctors. They appeared immune to their surroundings. CONCLUSION: Respondents ascribed little importance to the impact of current working conditions on their own health. They felt their roles were underappreciated and undervalued by policy makers and hospital management. Respondents were concerned with the lack of time and opportunity for training.

The majority of the Swiss population uses the internet to seek information about health. The objective is to be better informed, before or after the consultation. Doctors can advise their information-seeking patients about high quality websites, be it medical portals or websites dedicated to a specific pathology. Doctors should not see the internet as a threat but rather as an opportunity to strengthen the doctor-patient relationship.

Introduction The World Health Organization (WHO) identifies 8.7 million new cases of tuberculosis (TB) annually around the world. The unfavorable outcomes of TB treatment prevent the achievement of the WHO’s cure target. Goal To evaluate existing intersections in the conceptions relative to the knowledge of TB, the experience of the illness and the treatment. Methods Doctors, medical students and patients were selected from a public university in Rio de Janeiro, Brazil, from 2011 to 2013. The data were obtained by semi-structured individual and focus group interviews, participant observation and a field journal. The inclusion of patients was interrupted due to saturation, and the inclusion of doctors and medical students stopped due to exhaustion. The theoretical background included symbolic Interactionism, and the analysis used rounded Theory. The analysis prioritized the actions/interactions axis. Results Twenty-three patients with pulmonary TB, seven doctors and 15 medical students were included. In the interviews, themes such as stigma, self-segregation, and difficulties in assistance emerged, in addition to defense mechanisms such as denial, rationalization, isolation and other mental mechanisms, including guilt, accountability and concealment of the disease. Aspects related to the assistance strategy, the social support network, bonding with the healthcare staff and the doctor-patient relationship were highlighted as adherence enablers. Doctors and students recommended an expansion of the theoretical and practical instruction on TB during medical students’ education. The existence of health programs and policies was mentioned as a potential enabler of adherence. Conclusion The main concepts identified were the stigma, self-segregation, guilt, responsibility, concealment and emotional repercussions.

Psychiatric Prescribers' Experiences With Doctor Shoppers.
Worley, Julie; Johnson, Mary; Karnik, Niranjan
2015-01-01
Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs. © The Author(s) 2015.
Transparency masters for mathematics revealed
Berman, Elizabeth

Transparency Masters for Mathematics Revealed focuses on master diagrams that can be used for transparencies for an overhead projector or duplicator masters for worksheets. The book offers information on a compilation of master diagrams prepared by John R. Stafford, Jr., audiovisual supervisor at the University of Missouri at Kansas City. Some of the transparencies are designed to be shown horizontally. The initial three masters are number lines and grids that can be used in a mathematics course, while the others are adaptations of text figures which are slightly altered in some instances. The

Staff members of the Agency working at the Seibersdorf laboratory are continuing to achieve high academic distinction. Two more - both Austrian - have now been awarded the degree of Doctor of Agriculture. Joachim Kramer, who is 26, graduated from the Hochschule fur Bodenkultur in 1967 with the degree of Diplom-Ingenieur and then started work in the plant breeding and genetics section of the laboratory under the direction of Dr. Knut Mikaelsen. The results of the research work he carried out were accepted as the subject of a thesis for which he has now been granted his doctorate. The doctoral promotion took place on 30 June, at a ceremony attended by Dr. Andre Finkelstein, Deputy Director General for Research and Isotopes. The subject of Dr. Kramer's thesis was a comprehensive study of the mutagenic effects of fast neutrons and gamma rays, and the influence of various modifying factors such as water content, oxygen and metabolic state of seeds at the time of irradiation. This work has contributed significantly to the understanding of the mechanisms by which these two types of ionizing radiation produce mutations in seeds. The knowledge gained will be of great importance in the efficient use of ionizing radiation in practical plant breeding. Paul Wassermann, who is 33 years old, joined the Agency in 1965. He, too, graduated from the Hochschule fur Bodenkultur as Diplom-Ingenieur in agriculture, having graduated with honours previously from the agricultural secondary school at Raumberg, Austria, in 1958. Dr. Wassermann's own words may be used to explain how he came to gain his doctorate. 'In October, 1966, I completed my studies at the Hochschule,' he writes. 'I was employed at the Agency laboratories in Seibersdorf, working in the plant and soils group. Encouraged by the interesting research which was performed there, a thesis entitled 'the Fate of Nitrogen in Submerged Rice Soils' was started, which finally led to the doctor's degree in Agriculture in June this year

Full Text Available Abstract Background Standardization of analytical approaches and reporting methods via community-wide collaboration can work synergistically with web-tool development to result in rapid community-driven expansion of online data repositories suitable for data mining and meta-analysis. In metabolomics, the inter-laboratory reproducibility of gas-chromatography/mass-spectrometry (GC/MS makes it an obvious target for such development. While a number of web-tools offer access to datasets and/or tools for raw data processing and statistical analysis, none of these systems are currently set up to act as a public repository by easily accepting, processing and presenting publicly submitted GC/MS metabolomics datasets for public re-analysis. Description Here, we present MetabolomeExpress, a new File Transfer Protocol (FTP server and web-tool for the online storage, processing, visualisation and statistical re-analysis of publicly submitted GC/MS metabolomics datasets. Users may search a quality-controlled database of metabolite response statistics from publicly submitted datasets by a number of parameters (eg. metabolite, species, organ/biofluid etc.. Users may also perform meta-analysis comparisons of multiple independent experiments or re-analyse public primary datasets via user-friendly tools for t-test, principal components analysis, hierarchical cluster analysis and correlation analysis. They may interact with chromatograms, mass spectra and peak detection results via an integrated raw data viewer. Researchers who register for a free account may upload (via FTP their own data to the server for online processing via a novel raw data processing pipeline. Conclusions MetabolomeExpress https://www.metabolome-express.org provides a new opportunity for the general metabolomics community to transparently present online the raw and processed GC/MS data underlying their metabolomics publications. Transparent sharing of these data will allow researchers to
ENABLING USE OF STANDARD COSTING IN LEAN ORGANIZATIONS AS DETERMINANT OF GOAL CONGRUENT BEHAVIOR
DEFF Research Database (Denmark)
Kristensen, Thomas Borup; Israelsen, Poul
2014-01-01
Using the enabling formalization framework in two longitudinal case studies combined with a survey in the companies, we find that a standard costing model can be perceived as a form of enabling formalization in Lean organizations. Hence, standard costing cannot be characterized as coercive...... formalization per se. This contradicts conventional wisdom. Repair is a feature of enabling formalization through the use of standard costing. Applying a structural equation model, we present evidence that this repair feature has a direct effect on behavior that is congruent with Lean objectives. Internal...... and global transparency together with flexibility are three other features of enabling formalization through use of standard costing, but these have an indirect effect on Lean-goal-congruent behavior through the repair feature. Thus, these three features are antecedents of the repair feature, and we also...

Electromagnetically induced transparency with matched pulses
International Nuclear Information System (INIS)
Harris, S.E.
1993-01-01
In the last several years there have been studies and experiments showing how, by applying an additional laser beam, optically-thick transitions may be rendered nearly transparent to probing radiation. This transparency results from a quantum interference, very much like a Fano interference, which is established by the additional laser. This talk describes the difference between the quantum interference as exhibited by an independent atom and by an optically-thick ensemble of atoms. We find that an ensemble of atoms establishes transparency through a strong nonlinear interaction which, for a lambda system, tends to generate a matching temporal envelope on the complementary transition. For a ladder system, phase conjugate pulses are generated and, after a characteristic distance, establish transparency. The transparency of an optically-thick medium is therefore not a Beer's law superposition of the independent atom response. To transmit a pulse through an otherwise opaque media, the front edge of the complementary pulse should lead, in the manner of open-quotes counter-intuitiveclose quotes adiabatic transfer, the front edge of the pulse which is to be rendered transparent. Thereafter the pulses should be matched or, for a ladder system, phase-conjugately matched
Understanding how appraisal of doctors produces its effects: a realist review protocol.
Brennan, Nicola; Bryce, Marie; Pearson, Mark; Wong, Geoff; Cooper, Chris; Archer, Julian
2014-06-23
UK doctors are now required to participate in revalidation to maintain their licence to practise. Appraisal is a fundamental component of revalidation. However, objective evidence of appraisal changing doctors' behaviour and directly resulting in improved patient care is limited. In particular, it is not clear how the process of appraisal is supposed to change doctors' behaviour and improve clinical performance. The aim of this research is to understand how and why appraisal of doctors is supposed to produce its effect. Realist review is a theory-driven interpretive approach to evidence synthesis. It applies realist logic of inquiry to produce an explanatory analysis of an intervention that is, what works, for whom, in what circumstances, in what respects. Using a realist review approach, an initial programme theory of appraisal will be developed by consulting with key stakeholders in doctors' appraisal in expert panels (ethical approval is not required), and by searching the literature to identify relevant existing theories. The search strategy will have a number of phases including a combination of: (1) electronic database searching, for example, EMBASE, MEDLINE, the Cochrane Library, ASSIA, (2) 'cited by' articles search, (3) citation searching, (4) contacting authors and (5) grey literature searching. The search for evidence will be iteratively extended and refocused as the review progresses. Studies will be included based on their ability to provide data that enable testing of the programme theory. Data extraction will be conducted, for example, by note taking and annotation at different review stages as is consistent with the realist approach. The evidence will be synthesised using realist logic to interrogate the final programme theory of the impact of appraisal on doctors' performance. The synthesis results will be written up according to RAMESES guidelines and disseminated through peer-reviewed publication and presentations. The protocol is registered with

silica and a transparent conductive oxide demonstrated 90% visible transmission with high thermal infrared reflectivity characteristic of conventional low-e coatings. A slightly more complex stack provided high solar infrared reflection without sacrificing visible transmission or thermal infrared reflection. Successful completion of the effort produced a prototype integrated low-e, dynamic window film with characterized energy saving potential. Cost modeling for the passive bi-layer, low-e film projects a manufacturing cost of ~$0.50/ft2 for a plant with 10M ft2/yr capacity. The novel thin film processes developed here enable high deposition rate (low cost), optical quality oxide coatings at low temperatures. When combined with engineered materials, ITN’s coating will result in low-cost, low-e films that reflect a high degree of infrared radiation without substantially reducing the visible transmission. The resultant window film will improve the U-value and achieve SHGC improvements over bare glass. The new low-e coating will be particularly attractive when combined with an electrochromic film. Low-e coating design guided by energy savings modeling allows customization of the product for different climate zones.

2010-09-01
A study has been carried out by Togolese medical doctors in order to determine the perceived and the real life of their profession. The study, which was transversal, has taken in account a sample of 52 medical doctors made on the basis of a cautious choice. Most of these medical doctors (15 general practitioners, 23 specialists and 14 hospitalo-universitaires) work in the medical cares centres of Lomé. A sheet of survey has permitted the collection of demographic data and data relating to the medical studies and career. The 52 medical doctors included in the study (7 women, 45 men) were between 25 and 59 years old; their age of getting their A-level was between 16 and 23 years old, and that of getting the doctorate diploma between 24 and 37. The length of professional experience stands between 8 months and 27 years. The marital status was specified by 47 of the 52 medical doctors: 13 single, one divorced, and 33 married; 5 of the 7 women who took part in the survey were single and without any child. The love of the profession (65%), the social status it confers (37%) and the honour tied to the profession (27%) were the main motives of choosing the profession. The decision of doing medical studies was taken during secondary studies by 45 of the 52 persons. The faculty of medicine of Lomé has been the study frame to general medicine studies of 35 persons (67%). The low payment (83%), the poverty of the patients (83%), the narrowness of the technical platform (79%), the insufficiency of cares structures in paramedical personnel (67%), the insufficiency of continuing education (60%), and the lack or insufficiency of drugs (58%) were the main problems encountered during their professional experience by the people questioned. 22 medical doctors (43%) have estimated that their profession has given them a particular social status. Only 8 medical doctors have found that the real things they have gone trough in the profession matches with the idea they had, while 32 (62

Full Text Available There has been a seismic shift in the lives of people because of technology. People are far better informed than they were in the 1980s and 1990s. Much of this information is available through the media but even more is available and archived on the internet. The forces pushing the internet into health and health care are strong and unstoppable, ensuring that the internet and the choices it offers must be part of the design of our future health care system. We are no longer content to wait in queues as we live at a faster pace than earlier generations — we don’t not have time to wait for appointments months, weeks or even days in advance. The internet offers the prospect of online consultations in the comfort of your own home. The physical examination will change as new devices are developed to allow the necessary sounds and signals emitted by our malfunctioning bodies to be recorded, interpreted and captured at a remote location. Meanwhile, for those who prefer to see a health care practitioner in person the options to consult practitioners other than doctors who can advise on our health is expanding. The reality is we can’t afford to train or pay for all the doctors we need under the current “doctor-knows-best” system of health care. Patients no longer believe the rhetoric and are already voting with their feet. Pharmacists, nurses and other allied health professionals are beginning to play a much greater role in offering relief from symptoms and monitoring of chronic diseases. Of course, the doctor of the future will still need to offer face-to-face consultations to some people most of the time or most people some of the time. The social role doctors play will continue to be important as humans will always need other humans to personally respond to their distress. As doctors reinvent themselves, the internet and the value of time with patients will be the driving forces that move us into a more sustainable future in health care.

Reasons for consulting a doctor on the Internet: Web survey of users of an Ask the Doctor service.
Umefjord, Göran; Petersson, Göran; Hamberg, Katarina
2003-10-22
In 1998 the Swedish noncommercial public health service Infomedica opened an Ask the Doctor service on its Internet portal. At no charge, anyone with Internet access can use this service to ask questions about personal health-related and disease-related matters. To study why individuals choose to consult previously-unknown doctors on the Internet. Between November 1, 2001, and January 31, 2002 a Web survey of the 3622 Ask the Doctor service users, 1036 men (29%) and 2586 (71%) women, was conducted. We excluded 186 queries from users. The results are based on quantitative and qualitative analysis of the answers to the question "Why did you choose to ask a question at Infomedica's 'Ask the Doctor' service?" 1223 surveys were completed (response rate 36 %). Of the participants in the survey 322 (26%) were male and 901 (74%) female. As major reasons for choosing to consult previously-unknown doctors on the Internet participants indicated: convenience (52%), anonymity (36%), "doctors too busy" (21%), difficult to find time to visit a doctor (16%), difficulty to get an appointment (13%), feeling uncomfortable when seeing a doctor (9%), and not being able to afford a doctors' visit (3%). Further motives elicited through a qualitative analysis of free-text answers were: seeking a second opinion, discontent with previous doctors and a wish for a primary evaluation of a medical problem, asking embarrassing or sensitive questions, seeking information on behalf of relatives, preferring written communication, and (from responses by expatriates, travelers, and others) living far away from regular health care. We found that that an Internet based Ask the Doctor service is primarily consulted because it is convenient, but it may also be of value for individuals with needs that regular health care services have not been able to meet.

2017-05-31
Flexible transparent electronic devices have recently gained immense popularity in smart wearable electronics and touch screen devices, which accelerates the development of the portable power sources with reliable flexibility, robust transparency and integration to couple these electronic devices. For potentially coupled as energy storage modules in various flexible, transparent and portable electronics, the flexible transparent supercapacitors are developed and assembled from hierarchical nanocomposite films of reduced graphene oxide (rGO) and aligned polyaniline (PANI) nanoarrays upon their synergistic advantages. The nanocomposite films are fabricated from in situ PANI nanoarrays preparation in a blended solution of aniline monomers and rGO onto the flexible, transparent, and stably conducting film (FTCF) substrate, which is obtained by coating silver nanowires (Ag NWs) layer with Meyer rod and then coating of rGO layer on polyethylene terephthalate (PET) substrate. Optimization of the transparency, the specific capacitance, and the flexibility resulted in the obtained all-solid state nanocomposite supercapacitors exhibiting enhanced capacitance performance, good cycling stability, excellent flexibility, and superior transparency. It provides promising application prospects for exploiting flexible, low-cost, transparent, and high-performance energy storage devices to be coupled into various flexible, transparent, and wearable electronic devices.

To enable customized manufacturing of structural colors for commercial applications, up-scalable, low-cost, rapid, and versatile printing techniques are highly demanded. In this paper, we introduce a viable strategy for scaling up production of custom-input images by patterning individual structural colors on separate layers, which are then vertically stacked and recombined into full-color images. By applying this strategy on molded-ink-on-nanostructured-surface printing, we present an industry-applicable inkjet structural color printing technique termed multilayer molded-ink-on-nanostructured-surface (M-MIONS) printing, in which structural color pixels are molded on multiple layers of nanostructured surfaces. Transparent colorless titanium dioxide nanoparticles were inkjet-printed onto three separate transparent polymer substrates, and each substrate surface has one specific subwavelength grating pattern for molding the deposited nanoparticles into structural color pixels of red, green, or blue primary color. After index-matching lamination, the three layers were vertically stacked and bonded to display a color image. Each primary color can be printed into a range of different shades controlled through a half-tone process, and full colors were achieved by mixing primary colors from three layers. In our experiments, an image size as big as 10 cm by 10 cm was effortlessly achieved, and even larger images can potentially be printed on recombined grating surfaces. In one application example, the M-MIONS technique was used for printing customizable transparent color optical variable devices for protecting personalized security documents. In another example, a transparent diffractive color image printed with the M-MIONS technique was pasted onto a transparent panel for overlaying colorful information onto one's view of reality.
Clinical trials transparency and the Trial and Experimental Studies Transparency (TEST) act.
Logvinov, Ilana
2014-03-01
Clinical trial research is the cornerstone for successful advancement of medicine that provides hope for millions of people in the future. Full transparency in clinical trials may allow independent investigators to evaluate study designs, perform additional analysis of data, and potentially eliminate duplicate studies. Current regulatory system and publishers rely on investigators and pharmaceutical industries for complete and accurate reporting of results from completed clinical trials. Legislation seems to be the only way to enforce mandatory disclosure of results. The Trial and Experimental Studies Transparency (TEST) Act of 2012 was introduced to the legislators in the United States to promote greater transparency in research industry. Public safety and advancement of science are the driving forces for the proposed policy change. The TEST Act may benefit the society and researchers; however, there are major concerns with participants' privacy and intellectual property protection. Copyright © 2014 Elsevier Inc.

Full Text Available Abstract Background Doctors have a relatively high degree of emotional distress, but seek help to a lesser degree and at a later stage than other academic groups. This can be deleterious for themselves and for their patients. Prevention programs have therefore been developed but it is unclear to what extent they reach doctors in need of help. This study describes doctors who participated in a self-referrral, easily accessible, stress relieving, counselling program in Norway, and compares them with a nationwide sample of Norwegian doctors. Methods Two hundred and twenty seven (94% of the doctors, 117 women and 110 men, who came to the resort centre Villa Sana, Modum, Norway, between August 2003 and July 2005, agreed to participate in the study. Socio-demographic data, reasons for and ways of help-seeking, sick-leave, symptoms of depression and anxiety, job stress and burnout were assessed by self-reporting questionnaires. Results Forty-nine percent of the Sana doctors were emotionally exhausted (Maslach compared with 25% of all Norwegian doctors. However, they did not differ on empathy and working capacity, the other two dimensions in Maslach's burnout inventory. Seventy-three percent of the Sana doctors could be in need of treatment for depression or anxiety based on their symptom distress scores, compared with 14% of men and 18% of women doctors in Norway. Twenty-one percent of the Sana doctors had a history of suicidal thoughts, including how to commit the act, as compared to 10% of Norwegian doctors in general. Conclusion Sana doctors displayed a higher degree of emotional exhaustion, symptoms of depression and anxiety as well as job related stress, compared with all Norwegian doctors. This may indicate that the program at Villa Sana to a large extent reaches doctors in need of help. The counselling intervention can help doctors to evaluate their professional and private situation, and, when necessary, enhance motivation for seeking adequate

Full Text Available The aim of this critical literature review is to outline best practices in doctoral retention and the successful approach of one university to improve graduation success by providing effective mentorship for faculty and students alike. The focus of this literature review is on distance learning relationships between faculty and doctoral students, regarding retention, persistence, and mentoring models. Key phrases and words used in the search and focusing on mentoring resulted in over 20,000 sources. The search was narrowed to include only doctoral study and mentoring. Research questions of interest were: Why do high attrition rates exist for doctoral students? What are the barriers to retention? What are the benefits of doctoral mentoring? What programs do institutions have in place to reduce attrition? The researchers found a key factor influencing doctoral student retention and success is effective faculty mentorship. In particular, the design of a mentoring and faculty training program to increase retention and provide for success after graduation is important. This research represents a key area of interest in the retention literature, as institutions continue to search for ways to better support students during their doctoral programs and post-graduation.

EHR adoption among doctors who treat the elderly.
Yeager, Valerie A; Menachemi, Nir; Brooks, Robert G
2010-12-01
The purpose of this study is to examine Electronic Health Record (EHR) adoption among Florida doctors who treat the elderly. This analysis contributes to the EHR adoption literature by determining if doctors who disproportionately treat the elderly differ from their counterparts with respect to the utilization of an important quality-enhancing health information technology application. This study is based on a primary survey of a large, statewide sample of doctors practising in outpatient settings in Florida. Logistic regression analysis was used to determine whether doctors who treat a high volume of elderly (HVE) patients were different with respect to EHR adoption. Our analyses included responses from 1724 doctors. In multivariate analyses controlling for doctor age, training, computer sophistication, practice size and practice setting, HVE doctors were significantly less likely to adopt EHR. Specifically, compared with their counterparts, HVE doctors were observed to be 26.7% less likely to be utilizing an EHR system (OR=0.733, 95% CI 0.547-0.982). We also found that doctor age is negatively related to EHR adoption, and practice size and doctor computer savvy-ness is positively associated. Despite the fact that EHR adoption has improved in recent years, doctors in Florida who serve the elderly are less likely to adopt EHRs. As long as HVE doctors are adopting EHR systems at slower rates, the elderly patients treated by these doctors will be at a disadvantage with respect to potential benefits offered by this technology. © 2010 Blackwell Publishing Ltd.
Smart strategies for doctors and doctors-in-training: heuristics in medicine.
Wegwarth, Odette; Gaissmaier, Wolfgang; Gigerenzer, Gerd
2009-08-01
How do doctors make sound decisions when confronted with probabilistic data, time pressures and a heavy workload? One theory that has been embraced by many researchers is based on optimisation, which emphasises the need to integrate all information in order to arrive at sound decisions. This notion makes heuristics, which use less than complete information, appear as second-best strategies. In this article, we challenge this pessimistic view of heuristics. We introduce two medical problems that involve decision making to the reader: one concerns coronary care issues and the other macrolide prescriptions. In both settings, decision-making tools grounded in the principles of optimisation and heuristics, respectively, have been developed to assist doctors in making decisions. We explain the structure of each of these tools and compare their performance in terms of their facilitation of correct predictions. For decisions concerning both the coronary care unit and the prescribing of macrolides, we demonstrate that sacrificing information does not necessarily imply a forfeiting of predictive accuracy, but can sometimes even lead to better decisions. Subsequently, we discuss common misconceptions about heuristics and explain when and why ignoring parts of the available information can lead to the making of more robust predictions. Heuristics are neither good nor bad per se, but, if applied in situations to which they have been adapted, can be helpful companions for doctors and doctors-in-training. This, however, requires that heuristics in medicine be openly discussed, criticised, refined and then taught to doctors-in-training rather than being simply dismissed as harmful or irrelevant. A more uniform use of explicit and accepted heuristics has the potential to reduce variations in diagnoses and to improve medical care for patients.

Key opinion leaders (KOLs) are people who can influence public opinion on a certain subject matter. In the field of medical and health informatics, it is critical to identify KOLs on various disease conditions. However, there have been very few studies on this topic. We aimed to develop a recommender system for identifying KOLs for any specific disease with health care data mining. We exploited an unsupervised aggregation approach for integrating various ranking features to identify doctors who have the potential to be KOLs on a range of diseases. We introduce the design, implementation, and deployment details of the recommender system. This system collects the professional footprints of doctors, such as papers in scientific journals, presentation activities, patient advocacy, and media exposure, and uses them as ranking features to identify KOLs. We collected the information of 2,381,750 doctors in China from 3,657,797 medical journal papers they published, together with their profiles, academic publications, and funding. The empirical results demonstrated that our system outperformed several benchmark systems by a significant margin. Moreover, we conducted a case study in a real-world system to verify the applicability of our proposed method. Our results show that doctors' profiles and their academic publications are key data sources for identifying KOLs in the field of medical and health informatics. Moreover, we deployed the recommender system and applied the data service to a recommender system of the China-based Internet technology company NetEase. Patients can obtain authority ranking lists of doctors with this system on any given disease.

Barriers to expanding access to medicines include weak pharmaceutical sector governance, lack of transparency and accountability, inadequate attention to social services on the political agenda, and financing challenges. Multi-stakeholder initiatives such as the Medicines Transparency Alliance (MeTA) may help overcome these barriers. Between 2008 and 2015, MeTA engaged stakeholders in the pharmaceutical sectors of seven countries (Ghana, Jordan, Kyrgyzstan, Peru, Philippines, Uganda, and Zambia) to promote access goals through greater transparency. We reviewed archival data to document MeTA activities and results related to transparency and accountability in the seven countries where it was implemented. We identified common themes and content areas, noting specific activities used to make information transparent and accessible, how data were used to inform discussions, and the purpose and timing of meetings and advocacy activities to help set priorities and influence governance decisions. The cross-case analysis looked for pathways which might link the MeTA strategies to results such as better policies or program improvements. Countries used evidence gathering, open meetings, and proactive information dissemination to increase transparency. MeTA fostered policy dialogue to bring together the many government, civil society and private company stakeholders concerned with access issues, and provided them with information to understand barriers to access at policy, organizational, and community levels. We found strong evidence that transparency was enhanced. Some evidence suggests that MeTA efforts contributed to new policies and civil society capacity strengthening although the impact on government accountability is not clear. MeTA appears to have achieved its goal of creating a multi-stakeholder shared policy space in which government, civil society, and private sector players can come together and have a voice in the national pharmaceutical policy making process

Nurse prescribing in dermatology: doctors' and non-prescribing nurses' views.
Stenner, Karen; Carey, Nicola; Courtenay, Molly
2009-04-01
This paper is a report of a study conducted to explore doctor and non-prescribing nurse views about nurse prescribing in the light of their experience in dermatology. The cooperation of healthcare professionals and peers is of key importance in enabling and supporting nurse prescribing. Lack of understanding of and opposition to nurse prescribing are known barriers to its implementation. Given the important role they play, it is necessary to consider how the recent expansion of nurse prescribing rights in England impacts on the views of healthcare professionals. Interviews with 12 doctors and six non-prescribing nurses were conducted in 10 case study sites across England between 2006 and 2007. Participants all worked with nurses who prescribed for patients with dermatological conditions in secondary or primary care. Thematic analysis was conducted on the interview data. Participants were positive about their experiences of nurse prescribing having witnessed benefits from it, but had reservations about nurse prescribing in general. Acceptance was conditional upon the nurses' level of experience, awareness of their own limitations and the context in which they prescribed. Fears that nurses would prescribe beyond their level of competence were expected to reduce as understanding and experience of nurse prescribing increased. Indications are that nurse prescribing can be acceptable to doctors and nurses so long as it operates within recommended parameters. Greater promotion and assessment of standards and criteria are recommended to improve understanding and acceptance of nurse prescribing.
PDMS-based triboelectric and transparent nanogenerators with ZnO nanorod arrays.
Ko, Yeong Hwan; Nagaraju, Goli; Lee, Soo Hyun; Yu, Jae Su
2014-05-14
Vertically-grown ZnO nanorod arrays (NRAs) on indium tin oxide (ITO)-coated polyethylene terephthalate (PET), as a top electrode of nanogenerators, were investigated for the antireflective property as well as an efficient contact surface in bare polydimethysiloxane (PDMS)-based triboelectric nanogenerators. Compared to conventional ITO-coated PET (i.e., ITO/PET), the ZnO NRAs considerably suppressed the reflectance from 20 to 9.7% at wavelengths of 300-1100 nm, creating a highly transparent top electrode, as demonstrated by theoretical analysis. Also, the interval time between the peaks of generated output voltage under external pushing forces was significantly decreased from 1.84 to 0.19 s because the reduced contact area of the PDMS by discrete surfaces of the ZnO NRAs on ITO/PET causes a rapid sequence for triboelectric charge generation process including rubbing and separating. Therefore, the use of this top electrode enabled to operate the transparent PDMS-based triboelectric nanogenerator at high frequency of external pushing force. Under different external forces of 0.3-10 kgf, the output voltage and current were also characterized.

Towards Transparency in Finance and Governance
Tara Vishwanath; Daniel Kaufmann
2003-01-01
The study of transparency is increasingly a more topical, broadly relevant, but also more under-researched enterprise. The Asian financial crisis has highlighted not only the welfare consequences of financial sector transparency, sparking a series of yet unresolved debates, but has also linked this relatively narrow problem to the broader context of transparency in governance. Its significance has broadened geographically as well as across different sectors. It has been observed that curtailm...

1996-01-01
The objective of the Remote Monitoring Transparency Program is to evaluate and demonstrate the use of remote monitoring technologies to advance nonproliferation and transparency efforts that are currently being developed by Russia and the United States without compromising the national security to the participating parties. Under a lab-to-lab transparency contract between Sandia National Laboratories (SNL) and the Kurchatov Institute (KI RRC), the Kurchatov Institute will analyze technical and procedural aspects of the application of remote monitoring as a transparency measure to monitor inventories of direct- use HEU and plutonium (e.g., material recovered from dismantled nuclear weapons). A goal of this program is to assist a broad range of political and technical experts in learning more about remote monitoring technologies that could be used to implement nonproliferation, arms control, and other security and confidence building measures. Specifically, this program will: (1) begin integrating Russian technologies into remote monitoring systems; (2) develop remote monitoring procedures that will assist in the application of remote monitoring techniques to monitor inventories of HEU and Pu from dismantled nuclear weapons; and (3) conduct a workshop to review remote monitoring fundamentals, demonstrate an integrated US/Russian remote monitoring system, and discuss the impacts that remote monitoring will have on the national security of participating countries

Electromagnetically induced transparency in a multilevel system is investigated in 173 Yb. The level structure investigated is ''open'' in that the light that gives rise to the transparency also resonantly couples the atoms to excited states which do not exhibit electromagnetically induced transparency. The resulting reduction of transparency is investigated experimentally and theoretically. It is found that, while the transparency is poor in certain regimes, it can be made to perform arbitrarily well in the limit of a large intensity imbalance between the optical fields.

Unattached patients do not have a regular primary care provider. Initiatives are being developed to increase attachment rates across Canada. Most existing attention paid to patient unattachment has focused on quantifying the problem and health system costs. Our purpose is to qualitatively identify the implications of chronically ill patients' experiences of unattachment for health policy and planning to provide policy-relevant insights for Canadian attachment initiatives. Three focus groups were conducted with marginalized chronically ill individuals residing in a mid-sized city in British Columbia who are unattached to a family doctor. We use the term marginalized as a descriptor to acknowledge that by virtue of their low socio-economic status and lack of attachment the participants are marginalized in Canada's health care system Focus groups were structured as an open conversation organized around a series of probing questions. They were digitally recorded and transcribed verbatim. Thematic analysis was employed. Twenty-six individuals participated in the focus groups. The most common chronic illnesses reported were active drug addiction or recovery (and their associated symptoms), depression, arthritis, and hepatitis C. Participants identified life transitions as being the root cause for not having a family doctor. There was a strong sense that unsuccessful attempts to get a family doctor reflected that they were undesirable patients. Participants wanted to experience having a trusting relationship with a regular family doctor as they believed it would encourage greater honesty and transparency. One of the main health concerns regarding lack of access to a regular family doctor is that participants lacked access to preventative care. Participants were also concerned about having a discontinuous medical record due to unattachment. Participants perceived that there are many benefits to be had by having attachment to a regular family doctor and that experiencing

Marketing of cosmetics often makes strong claims linked to active ingredients. This is especially so for anti-ageing products, where the presentation and content of "active" ingredients may create new difficulties in their classification as cosmetics or medicinal products. A recent change in European legislation classifies a product as medicinal by virtue of its "function", in addition to the previous definition of "presentation" (i.e. marketing linked to diseases). Thus, formulations that also restore, correct or modify physiological functions by exerting a pharmacological, immunological or metabolic action should henceforth be covered by the Medicinal Products Directive. A cosmetic product must be suitable for its purpose and should not lead to adverse reactions that are disproportional in relation to its intended effect. However, the forthcoming ban on animal testing of cosmetic ingredients and the new European regulation, REACH (Registration, Evaluation and Authorisation of Chemicals), which aims to ensure a high level of chemical safety to protect human health and the environment, will probably have limited impact on the safety assessment of cosmetics. In order to enable consumers to make informed purchasing decisions, greater transparency in the process of assessing the performance of cosmetics is needed. Introduction of a more transparent system, enabling consumers and professionals to examine the scientific evidence for the claimed effect and the safety assessment of cosmetics, is therefore timely. Lack of transparency increases the risk of consumers wasting money on cosmetics that do not deliver the desired effects. This may jeopardize public trust in the cosmetic industry.
Conceptualising Doctoral Writing as an Affective-political Practice

James Burford
2017-03-01
Full Text Available Aim/Purpose: This article offers a conceptual summary and critique of existing literature on doctoral writing and emotion. The article seeks to intervene in current debates about doctoral writing by re-positioning it as an affective-political practice Background: Over recent decades public interest in the doctorate has expanded as it has become re-framed as a key component of national success in the global knowledge economy. It is within this context that the practice of doctoral writing has crystallised as an object of interest. While researchers have examined the increased regulation, surveillance, and intensification of doctoral writing, often this work is motivated to develop pedagogies that support students to meet these new expectations. At this point, there has been limited attention to what broad changes to the meanings and practices of doctoral writing feel like for students. Methodology: The paper offers a conceptual review that examines the ways in which doctoral writing tends to be understood. A review of literature in the areas of doctoral writing, doctoral emotion, and critical studies of academic labour was undertaken in order to produce a more comprehensive understanding of the political and emotional dynamics of doctoral writing. Contribution: It is intended that this conceptual research paper help researchers attend to the emotional context of doctoral writing in the current university context. Critical studies of academic work and life are identified as a possible platform for the development of future doctoral education research, and the conceptual tool of “affective-politics” is advanced as a novel frame for approaching doctoral writing research.

The aim of this study was to investigate whether a patient's preference for a doctor's face is associated with better assessments of relational empathy in the patient-doctor relationship after the first clinical consultation. A total of 110 patients enrolled in a traditional Korean medical clinic participated in the study. Patients' preference for doctors' faces was assessed by a two alternative forced choice (2AFC) task, with 60 different pairs of six different Asian male doctors' faces. One of the six doctors then carried out the initial clinical consultation for these patients. The patient-doctor relationship was assessed using the Consultation and Relational Empathy (CARE) measure. The data of all patients' simulated preferences for a doctor's face and their assessment values of a doctor's relational empathy was compared, and no significant correlation was found between both values (r=-0.024, p>0.809). These findings suggest that the perceived empathy in the patient-doctor relationship is not influenced by the patient's preference for a certain doctor's face. The first impression of a doctor is often determined by his appearance and look. However, whether or not the patient particularly prefers a doctor's face does not seem to matter in developing a good patient-doctor relationship.

Objective To report on any adverse effects on health and wellbeing of working as a doctor, as described by senior doctors. Design Questionnaires sent in 2014 to all medical graduates of 1974 and 1977. Participants 3695 UK medical graduates. Setting United Kingdom. Main outcome measures Statements about adverse effects upon health, wellbeing and career. Results The aggregated response rate from contactable doctors was 84.6% (3695/4369). In response to the question 'Do you feel that working as a doctor has had any adverse effects on your own health or wellbeing?', 44% of doctors answered 'yes'. More GPs (47%) than hospital doctors (42%) specified that this was the case. Three-quarters of doctors who answered 'yes' cited 'stress/work-life balance/workload' as an adverse effect, and 45% mentioned illness. In response to the statement 'The NHS of today is a good employer when doctors become ill themselves', 28% of doctors agreed, 29% neither agreed nor disagreed and 43% disagreed. More women doctors (49%) than men doctors (40%) disagreed with this statement. More general practitioners (49%) disagreed than hospital doctors (37%). Conclusions Chronic stress and illness, which these doctors attributed to their work, were widely reported. Although recent changes may have alleviated some of these issues, there are lessons for the present and future if the NHS is to ensure that its medical workforce receives the support which enables current doctors to enjoy a full and satisfying career and to contribute fully to health service provision in the UK. Older doctors, in particular, need support to be able to continue successfully in their careers.
Running an open experiment: transparency and reproducibility in soil and ecosystem science
Bond-Lamberty, Ben; Peyton Smith, A.; Bailey, Vanessa
2016-08-01
Researchers in soil and ecosystem science, and almost every other field, are being pushed—by funders, journals, governments, and their peers—to increase transparency and reproducibility of their work. A key part of this effort is a move towards open data as a way to fight post-publication data loss, improve data and code quality, enable powerful meta- and cross-disciplinary analyses, and increase trust in, and the efficiency of, publicly-funded research. Many scientists however lack experience in, and may be unsure of the benefits of, making their data and fully-reproducible analyses publicly available. Here we describe a recent ‘open experiment’, in which we documented every aspect of a soil incubation online, making all raw data, scripts, diagnostics, final analyses, and manuscripts available in real time. We found that using tools such as version control, issue tracking, and open-source statistical software improved data integrity, accelerated our team’s communication and productivity, and ensured transparency. There are many avenues to improve scientific reproducibility and data availability, of which is this only one example, and it is not an approach suited for every experiment or situation. Nonetheless, we encourage the communities in our respective fields to consider its advantages, and to lead rather than follow with respect to scientific reproducibility, transparency, and data availability.
Nuclear deterrence: which environmental transparency?
International Nuclear Information System (INIS)
Cherief, Hamza
2012-01-01
This article addresses the field of nuclear geopolitics. The author discusses the tensions between the principle of transparency regarding environmental issues on the one hand, and the protection of nuclear deterrence as instrument of power on the other hand. According to the French law, the preservation of nuclear power instruments means the acknowledgement of a legal regime which is specific to national defence requirements in terms of secret and right to information. Thus, the author discusses the constitutional limitations of the environmental transparency obligation for the protection of Nation's fundamental interests. Then, by commenting the Rainbow Warrior affair, the author highlights the exceptional limitations of the transparency requirement regarding nuclear issues

To identify the impact of family life on the ways women practice rural medicine and the changes needed to attract women to rural practice. Census of women rural doctors in Victoria in 2000, using a self-completed postal survey. General and specialist practice. Two hundred and seventy-one female general practitioners and 31 female specialists practising in Rural, Remote and Metropolitan Area Classifications 3-7. General practitioners are those doctors with a primary medical degree and without additional specialist qualifications. Interaction of hours and type of work with family responsibilities. Generalist and specialist women rural doctors carry the main responsibility for family care. This is reflected in the number of hours they work in clinical and non-clinical professional practice, availability for on-call and hospital work, and preference for the responsibilities of practice partnership or the flexibility of salaried positions. Most of the doctors had established a satisfactory balance between work and family responsibilities, although a substantial number were overworked in order to provide an income for their families or meet the needs of their communities. Thirty-six percent of female rural general practitioners and 56% of female rural specialists preferred to work fewer hours. Female general practitioners with responsibility for children were more than twice as likely as female general practitioners without children to be in a salaried position and less likely to be a practice partner. The changes needed to attract and retain women in rural practice include a place for everyone in the doctor's family, flexible practice structures, mentoring by women doctors and financial and personal recognition. Women make up less than a quarter of the rural general practice workforce and an even smaller percentage of the specialist rural medical workforce. As a result their experiences are not well articulated in research on rural medical practice and their needs are

Full Text Available Abstract Background Emergency departments continuously provide medical treatment on a walk-in basis. Several studies investigated the patient's perception of the doctor-patient relationship, but few have asked doctors about their views. Furthermore, the influence of the patient's ethnicity and gender on the doctor's perception remains largely unanswered. Methods Based on data collated in three gynaecology (GYN/internal medicine (INT emergency departments in Berlin, Germany, we evaluated the impact of the patient's gender and ethnicity on the doctors' satisfaction with the course of the treatment they provided. Information was gathered from 2.429 short questionnaires completed by doctors and the medical records of the corresponding patients. Results The patient's ethnicity had a significant impact on the doctors' satisfaction with the doctor-patient relationship. Logistic regression analysis showed that the odds ratio (OR for physician satisfaction was significantly lower for patients of Turkish origin (OR = 2.6 INT and 5.5 GYN than for those of German origin. The main reasons stated were problems with communication and a perceived lack of urgency for emergency treatment. The odds ratios for dissatisfaction due to a lack of language skills were 4.48 (INT and 6.22 (GYN, and those due to perceived lack of urgency for emergency treatment were 0.75 (INT and 0.63 (GYN. Sex differences caused minor variation. Conclusion The results show that good communication despite language barriers is crucial in providing medical care that is satisfactory to both patient and doctors, especially in emergency situations. Therefore the use of professional interpreters for improved communication and the training of medical staff for improved intercultural competence are essential for the provision of adequate health care in a multicultural setting.

A fabrication method for transparent ambipolar organic thin film transistors with transparent Sb{sub 2}O{sub 3}/Ag/Sb{sub 2}O{sub 3} (SAS) source and drain electrodes has been developed. A pentacene/N,N′-ditridecylperylene-3,4,9,10-tetracarboxylic di-imide (PTCDI-C13) bilayer heterojunction is used as the active semiconductor. The electrodes are deposited by room temperature electron beam evaporation. The devices are fabricated without damaging the active layers. The SAS electrodes have high transmittance (82.5%) and low sheet resistance (8 Ω/sq). High performance devices with hole and electron mobilities of 0.3 cm{sup 2}/V s and 0.027 cm{sup 2}/V s, respectively, and average visible range transmittance of 72% were obtained. These transistors have potential for transparent logic integrated circuit applications.

Transparency has become a catchword and in the economic-political debate is often seen as a universal remedy for all sorts of problems. In this paper, we analyze and discuss the meaning and use of the concept of transparency in economic research. We look for common denominators across different areas where the concept is used, and find that transparency in essence is about reductions in information asymmetries, and therefore entails the transfer of information from a sender to a receiver.

Today's healthcare can be characterised by the increasing importance of specialisation that requires cooperation across disciplines and specialities. In view of the number of educational programmes for interdisciplinary cooperation, surprisingly little is known on how learning arises from interdisciplinary work. In order to analyse the learning and teaching practices of interdisciplinary cooperation, a multiple case study research focused on how consults, i.e., doctor-to-doctor consultations between medical doctors from different disciplines were carried out: semi-structured interviews with doctors of all levels of seniority from two hospital sites in Switzerland were conducted. Starting with a priori constructs based on the 'methods' underpinning cognitive apprenticeship (CA), the transcribed interviews were analysed according to the principles of qualitative content analysis. The research contributes to three debates: (1) socio-cognitive and situated learning, (2) intra- and interdisciplinary learning in clinical settings, and (3), more generally, to cooperation and problem solving. Patient cases, which necessitate the cooperation of doctors in consults across boundaries of clinical specialisms, trigger intra- as well as interdisciplinary learning and offer numerous and varied opportunities for learning by requesting doctors as well as for on-call doctors, in particular those in residence. The relevance of consults for learning can also be verified from the perspective of CA which is commonly used by experts, albeit in varying forms, degrees of frequency and quality, and valued by learners. Through data analysis a model for collaborative problem-solving and help-seeking was developed which shows the interplay of pedagogical 'methods' of CA in informal clinical learning contexts.
Effective doctor-patient communication: an updated examination.
Matusitz, Jonathan; Spear, Jennifer
2014-01-01
This article examines, in detail, the quality of doctor-patient interaction. Doctor-patient communication is such a powerful indicator of health care quality that it can determine patients' self-management behavior and health outcomes. The medical visit (i.e., the medical encounter) plays a pivotal role in the health care process. In fact, doctor-patient communication is one of the most essential dynamics in health care, affecting the course of patient care and patient compliance with recommendations for care. Unlike many other analyses (that often look at only one or two specific aspects of doctor-patient relationships), this analysis is more encompassing; it looks at doctor-patient communication from multiple perspectives.

In this study, we define the state-level nuclear transparency as a set of the condition that shows how clearly the state's information related to peaceful nuclear power program and nuclear proliferation is revealed to the international community. For conducting expert survey on state-level nuclear transparency, the concept of nuclear transparency should be clearly defined. Based on that concept, the survey was carried out and results show that it tend to score high when nonproliferation activities happen. It means that higher transparency is positively related to nuclear proliferation. Therefore, higher nuclear transparency is positively related to nuclear nonproliferation.

Developing a psychiatrist-patient relationship when both people are doctors: a qualitative study.
Stanton, Josephine; Randal, Patte
2016-05-20
To better understand the complexities of developing an effective psychiatrist-patient relationship when both people involved are doctors. In-depth, semistructured interviews were conducted with 11 doctors with experiences as patients of psychiatrists (DPs) and eight psychiatrists with experience of treating doctors (TPs). A thematic analysis was undertaken. The medical culture of unrealistically high standards with limited room for vulnerability and fallibility, vigilance for judgment and valuing clinical over personal knowledge affected both people in the relationship. DPs struggled with the contradictions involved in entering the patient role but tried hard to be good patients. They wanted guidance but found it hard to accept and seldom communicated dissatisfaction or disagreement to their TPs. They described widely varying responses to diagnosis and treatment within the biomedical model. TPs described enjoyment and satisfaction and extreme challenge in engaging with TPs. Despite focusing on providing ordinary care they described providing extra care in many ways. This study brings forward important issues when a psychiatrist is building a therapeutic relationship with another doctor. These are also likely to arise with other people and contribute to making truly patient-centred 'ordinary care' a hard ideal to fulfil. They include: (1) doctors' sense of ourselves as invincible, (2) TPs' sense of personal connection to, and identity with, DPs, (3) having extensive medical knowledge and (4) striving to be good patients. We need to make these issues explicit and enable the DP (or other patients) to tell their story and speak about their experience of the consultation so that any potential rupture in the therapeutic relationship can be addressed early.

In 2009, health-care reform was launched to achieve universal health coverage in China. A good understanding of how China's health reforms are influencing village doctors' income structure will assist authorities to adjust related polices and ensure that village doctors employment conditions enable them to remain motivated and productive. This study aimed to investigate the village doctors' income structure and analyse how these health policies influenced it. Based on a review of the previous literature and qualitative study, village doctors' income structure was depicted and analysed. A qualitative study was conducted in six counties of six provinces in China from August 2013 to January 2014. Forty-nine village doctors participated in in-depth interviews designed to document their income structure and its influencing factors. The themes and subthemes of key factors influencing village doctors' income structure were analysed and determined by a thematic analysis approach and group discussion. Several policies launched during China's 2009 health-care reform had major impact on village doctors. The National Essential Medicines System cancelled drug mark-ups, removing their primary source of income. The government implemented a series of measures to compensate, including paying them to implement public health activities and provide services covered by social health insurance, but these have also changed the village doctors' role. Moreover, integrated management of village doctors' activities by township-level staff has reduced their independence, and different counties' economic status and health reform processes have also led to inconsistencies in village doctors' payment. These changes have dramatically reduced village doctors' income and employment satisfaction. The health-care reform policies have had lasting impacts on village doctors' income structure since the policies' implementation in 2009. The village doctors have to rely on the salaries and subsidies from

But what does it mean – in practice – especially when it comes to Board transparency – i.e. the ability of shareholders to gain knowledge about an organization’s corporate governance practices in order to make an informed assessment of Directors’ individual and collective roles and performance. In a preliminary investigation of Board transparency practices in Canadian listed firms (using data from 2003-2004, it was found that there were wide variations in the nature and quantity of corporate governance practices disclosed. The reasons for these variations are discussed and a number of recommendations for improved disclosure are presented.

Recent developments of transparent electrode arrays provide a unique capability for simultaneous optical and electrical interrogation of neural circuits in the brain. However, none of these electrode arrays possess the stretchability highly desired for interfacing with mechanically active neural systems, such as the brain under injury, the spinal cord, and the peripheral nervous system (PNS). Here, we report a stretchable transparent electrode array from carbon nanotube (CNT) web-like thin films that retains excellent electrochemical performance and broad-band optical transparency under stretching and is highly durable under cyclic stretching deformation. We show that the CNT electrodes record well-defined neuronal response signals with negligible light-induced artifacts from cortical surfaces under optogenetic stimulation. Simultaneous two-photon calcium imaging through the transparent CNT electrodes from cortical surfaces of GCaMP-expressing mice with epilepsy shows individual activated neurons in brain regions from which the concurrent electrical recording is taken, thus providing complementary cellular information in addition to the high-temporal-resolution electrical recording. Notably, the studies on rats show that the CNT electrodes remain operational during and after brain contusion that involves the rapid deformation of both the electrode array and brain tissue. This enables real-time, continuous electrophysiological monitoring of cortical activity under traumatic brain injury. These results highlight the potential application of the stretchable transparent CNT electrode arrays in combining electrical and optical modalities to study neural circuits, especially under mechanically active conditions, which could potentially provide important new insights into the local circuit dynamics of the spinal cord and PNS as well as the mechanism underlying traumatic injuries of the nervous system.

The term house doctor may be generalized to include persons skilled in the use of instruments and procedures necessary to identify, diagnose, and correct indoor air quality problems as well as energy, infiltration, and structural problems in houses. A radon house doctor would then be a specialist in radon house problems. Valuable experience in the skills necessary to be developed by radon house doctors has recently been gained in an extensive radon monitoring and mitigation program in upstate New York sponsored by Niagara Mohawk Power Corporation and the New York State Energy Research and Development Authority. These skills, to be described in detail in this paper, include: (i) the use of appropriate instruments, (ii) the evaluation of the symptoms of a radon-sick house, (iii) the diagnostic procedures required to characterize radon sources in houses, (iv) the prescription procedures needed to specify treatment of the problem, (v) the supervision of the implementation of the treatment program, (vi) the check-up procedures required to insure the house cured of radon problems. 31 references, 3 tables
Women who doctor shop for prescription drugs.
Worley, Julie; Thomas, Sandra P
2014-04-01
Doctor shopping is a term used to describe a form of diversion of prescription drugs when patients visit numerous prescribers to obtain controlled drugs for illicit use. Gender differences exist in regard to prescription drug abuse and methods of diversion. The purpose of this phenomenological study guided by the existential philosophy of Merleau-Ponty was to understand the lived experience of female doctor shoppers. Interviews were conducted with 14 women, which were recorded, transcribed, and analyzed. Included in the findings are figural aspects of the participants' experience of doctor shopping related to the existential grounds of world, time, body, and others. Four themes emerged from the data: (a) feeding the addiction, (b) networking with addicts, (c) playing the system, and (d) baiting the doctors. The findings suggest several measures that nurses can take to reduce the incidence of doctor shopping and to provide better care for female doctor shoppers.
One-step sub-10 μm patterning of carbon-nanotube thin films for transparent conductor applications.
Fukaya, Norihiro; Kim, Dong Young; Kishimoto, Shigeru; Noda, Suguru; Ohno, Yutaka
2014-04-22
We propose a technique for one-step micropatterning of as-grown carbon-nanotube films on a plastic substrate with sub-10 μm resolution on the basis of the dry transfer process. By utilizing this technique, we demonstrated the novel high-performance flexible carbon-nanotube transparent conductive film with a microgrid structure, which enabled improvement of the performance over the trade-off between the sheet resistance and transmittance of a conventional uniform carbon-nanotube film. The sheet resistance was reduced by 46% at its maximum by adding the microgrid, leading to a value of 53 Ω/sq at a transmittance of 80%. We also demonstrated easy fabrication of multitouch projected capacitive sensors with 12 × 12 electrodes. The technique is quite promising for energy-saving production of transparent conductor devices with 100% material utilization.

The Cape doctor 1807-1910: perspectives.
Phillips, Howard
2004-01-01
This chapter contrasts the Cape doctor in 1807 and in 1910, and finds that, in a whole variety of ways, the differences between the two were not of degree but of kind. Underlying this sea-change was the germ revolution of the late Victorian era, which transformed the Cape doctor out of all recognition, thereby laying important foundations for the development of the twentieth-century South African doctor.
Transparency in Nuclear Regulation: Trends and Future Prospects

2007-01-01
Recently, improving transparency (or openness) has been one of important issues related to nuclear safety worldwide. As for the transparency in nuclear regulatory activities in Korea, openness has been declared as one of five principles of the nuclear regulation in the 'nuclear safety policy statement' announced in 1994. Transparency has been discussed and emphasized in various international meetings such as the Convention on Nuclear Safety, OECD/NEA meetings, etc. For example, Working Group on Public Communication of nuclear regulatory organizations (WGPC) of the OECD/NEA/CNRA held a workshop on 'the transparency of nuclear regulatory activities' in May 2007 in Tokyo, Japan. In this paper, definition of transparency and its international trends ranging from a general administration to nuclear safety activities are discussed based on the results of meetings and workshops held so far. Measures for improvement associated with transparency are also proposed

Transparency in Europe: A Quantitative Study.
Bouder, Frederic; Way, Dominic; Löfstedt, Ragnar; Evensen, Darrick
2015-07-01
In recent years, European pharmaceutical regulators have increasingly committed to heightening access to raw safety-related data as part of a wave of transparency initiatives (e.g., providing public Internet-mediated access to clinical trials data). Yet, the regulators--who are under significant pressure--have not yet benefited from a systematic review of this new policy. In seeking to inject much needed evidence, this article explores the effects of new transparency policies designed to promote meaningful communication of risks and benefits to patients. Results of a cross-national European survey with respondents from Great Britain, the Netherlands, Spain, France, Germany, and Sweden (N = 5,648) shed light on how patients and the public are likely to react to the regulators' new transparency policies. The findings demonstrate clear national variations in how European citizens are likely to react and emphasize the need to develop evidence-based, reasoned transparency policies that integrate benefit-risk communication. The authors conclude by providing six specific recommendations, informed by the study, that seek to improve the European transparency model both within the medical field and across health, safety, and environmental policy domains. © 2015 Society for Risk Analysis.
PUBLIC SECTOR TRANSPARENCY:A CONCEPTUAL DISSECTION

Full Text Available The concept of transparency has increasingly attracted the attention of academic, political and business areas. Many studies have demonstrated the need for adopting this corporate governance principle also in the public sector, a phenomenon that has become widespread at international level. The academic study field defines transparency as the ability to look clearly through the window of an institution. Starting from this statement, the research focuses on the importance of transparency in public governance and on the framework for identifying and assessing this concept. Furthermore, this paper also analysis the limits of this notion in order to maintain its significance and effectiveness. Thus, based on the literature review, this study summarizes the opinions and arguments of various authors in the field regarding the notion of transparency in the public sector. At the same time, it analysis the conclusions of empirical studies on this topic. The results of the study reveal the importance and necessity of information disclosure among different users for increasing citizens' trust in government and achieving good governance. However, the positive aspects of transparency tend to be overestimated and considering the ambiguity of this concept it should be carefully handled.
Transparent soil for imaging the rhizosphere.

Full Text Available Understanding of soil processes is essential for addressing the global issues of food security, disease transmission and climate change. However, techniques for observing soil biology are lacking. We present a heterogeneous, porous, transparent substrate for in situ 3D imaging of living plants and root-associated microorganisms using particles of the transparent polymer, Nafion, and a solution with matching optical properties. Minerals and fluorescent dyes were adsorbed onto the Nafion particles for nutrient supply and imaging of pore size and geometry. Plant growth in transparent soil was similar to that in soil. We imaged colonization of lettuce roots by the human bacterial pathogen Escherichia coli O157:H7 showing micro-colony development. Micro-colonies may contribute to bacterial survival in soil. Transparent soil has applications in root biology, crop genetics and soil microbiology.

2D semiconductors are poised to revolutionize the future of electronics and photonics, much like transparent oxide conductors and semiconductors have revolutionized the display industry. Herein, these two types of materials are combined to realize fully transparent 2D electronic devices and circuits. Specifically, a large-area chemical vapor deposition process is developed to grow monolayer MoS2 continuous films, which are, for the first time, combined with transparent conducting oxide (TCO) contacts. Transparent conducting aluminum doped zinc oxide contacts are deposited by atomic layer deposition, with composition tuning to achieve optimal conductivity and band-offsets with MoS2. The optimized process gives fully transparent TCO/MoS2 2D electronics with average visible-range transmittance of 85%. The transistors show high mobility (4.2 cm2 V−1 s−1), fast switching speed (0.114 V dec−1), very low threshold voltage (0.69 V), and large switching ratio (4 × 108). To our knowledge, these are the lowest threshold voltage and subthreshold swing values reported for monolayer chemical vapor deposition MoS2 transistors. The transparent inverters show fast switching properties with a gain of 155 at a supply voltage of 10 V. The results demonstrate that transparent conducting oxides can be used as contact materials for 2D semiconductors, which opens new possibilities in 2D electronic and photonic applications.
Fiscal Transparency and Procyclical Fiscal Policy

This paper examines why fiscal policy is procyclical in developing as well as developed countries. We introduce the concept of fiscal transparency into a model of retrospective voting, in which a political agency problem between voters and politicians generates a procyclical bias in government...... spending. The introduction of fiscal transparency generates two new predictions: 1) the procyclical bias in fiscal policy arises only in good times; and 2) a higher degree of fiscal transparency reduces the bias in good times. We find solid empirical support for both predictions using data on both OECD...

Bottom-up fabrication of a flexible multi-touch panel prototype based on transparent colloidal indium tin oxide (ITO) nanocrystal (NC) films is presented. A series of 7% Sn(4+) doped ITO NCs protected by oleate, octanoate and butanoate ligands are synthesized and characterized by a battery of techniques including, high resolution transmission electron microscopy, X-ray diffraction, (1)H, (13)C and (119)Sn nuclear magnetic resonance spectroscopy, and the related diffusion ordered spectroscopy. Electrical resistivities of transparent films of these NCs assembled on flexible polyethylene terephthalate substrates by convective self-assembly from their suspension in toluene decrease with the ligand length, from 220 × 10(3) for oleate ITO to 13 × 10(3)Ω cm for butanoate ITO NC films. A highly transparent, flexible touch panel based on a matrix of strain gauges derived from the least resistive film of 17 nm butanoate ITO NCs sensitively detects the lateral position (x, y) of the touch as well as its intensity over the z-axis. Being compatible with a stylus or bare/gloved finger, a larger version of this module may be readily implemented in upcoming flexible screens, enabling navigation capabilities over all three axes, a feature highly desired by the display industry.

Requiring hospitals to inform patients of clinical best practices and to disclose performance data are two common regulatory strategies for improving healthcare. Proponents of such mandatory disclosure laws--sometimes referred to as "targeted transparency "--argue that they increase patient awareness and thereby create reputational incentives for hospitals to improve their performance. Evaluation of targeted transparency typically focuses on patient responses to information and changes in hospital behavior based on reputational concerns. This standard account, however, overlooks other important ways targeted transparency can influence hospital performance. This article presents a case study of disclosure laws designed to promote breastfeeding to illustrate how targeted transparency can influence hospitals independently of its effects on patients' choice of provider or hospitals' fear of losing business. We found that mandatory disclosure laws emboldened state regulators to take a more aggressive approach to enforcement of hospital regulations, empowered nurse managers to advocate more effectively within hospitals for changes in hospital policies, and enabled nurse managers to implement verifiable performance goals for clinical staff under their supervision. These findings suggest that the study of mandatory disclosure more generally--in areas such as financial regulation, environmental protection, food labeling, and workplace safety--would benefit by analyzing not only its influence on public awareness and its reputational effects but also how regulators use transparency laws and how managers within regulated entities employ the information that the laws provide.

This study proposes that price transparency is a significant factor affecting customer judgments of the fairness of sellers’ prices. Cognitive judgments of fairness require a certain amount of information processing; therefore, the level of transparency and the amount of price information affect fairness judgments. The more clear information consumers possess concerning seller prices, the more positive the judgment will be. Customer price fairness judgment is an effective measurement for the ...

Herein, we report the fabrication of a highly stretchable, transparent gas sensor based on silver nanowire-graphene hybrid nanostructures. Due to its superb mechanical and optical characteristics, the fabricated sensor demonstrates outstanding and stable performances even under extreme mechanical deformation (stable until 20% of strain). The integration of a Bluetooth system or an inductive antenna enables the wireless operation of the sensor. In addition, the mechanical robustness of the materials allows the device to be transferred onto various nonplanar substrates, including a watch, a bicycle light, and the leaves of live plants, thereby achieving next-generation sensing electronics for the `Internet of Things' area.Herein, we report the fabrication of a highly stretchable, transparent gas sensor based on silver nanowire-graphene hybrid nanostructures.

Laser processing of optically transparent or semi-transparent, brittle materials is finding wide use in various manufacturing sectors. For example, in consumer electronic devices such as smartphones or tablets, cover glass needs to be cut precisely in various shapes. The unique advantage of material processing with femtosecond lasers is efficient, fast and localized energy deposition in nearly all types of solid materials. When an ultra-short laser pulse is focused inside glass, only the localized region in the neighborhood of the focal volume absorbs laser energy by nonlinear optical absorption. Therefore, the processing volume is strongly defined, while the rest of the target stays unaffected. Thus ultra-short pulse lasers allow cutting of the chemically strengthened glasses such as Corning Gorilla glass without cracking. Non-ablative cutting of transparent, brittle materials, using the newly developed femtosecond process ClearShapeTM from Spectra-Physics, is based on producing a micron-sized material modification track with well-defined geometry inside. The key point for development of the process is to understand the induced modification by a single femtosecond laser shot. In this paper, pump-probe microscopy techniques have been applied to study the defect formation inside of transparent materials, namely soda-lime glass samples, on a time scale between one nanosecond to several tens of microseconds. The observed effects include acoustic wave propagation as well as mechanical stress formation in the bulk of the glass. Besides better understanding of underlying physical mechanisms, our experimental observations have enabled us to find optimal process parameters for the glass cutting application and lead to better quality and speed for the ClearShapeTM process.
Multidirectional Networks of Government Transparency: A Preliminary Model
Directory of Open Access Journals (Sweden)
Ahmad Subhan
2016-11-01
Full Text Available This article reviews some literature in theoretical level regarding two concepts: governance network and government transparency, in order to search for theoretical linkages and to build an alternative framework that can support the implementation of public disclosure. Transparency agenda has been implemented in various forms at international, national, and local level. Transparency application was also followed by Indonesia with the implementation of Public Information Disclosure Law since 2008. This enthusiasm is quite reasonable because transparency is believed to be one of the human rights principles; as well as a key to better governance, that can help democracy consolidation, prevent corruption, strengthen the legitimacy and improve efficiency. In order to maximize transparency, the government can use a network approach because of some changes at this time, such as democratization, decentralization, and liberalization has placed the government in a position where there is not one actor who manages the state power without stakeholder’s participation. In this context, the government needs to build synergies with other institutions in a reciprocal relationship with all stakeholders. Therefore, adopting the theory of government networks can be one of the strategies to strengthen government transparency. The findings of this article indicate that the government transparency application needs to develop networks in all directions: intragovernmental, intergovernmental and collaborative networks. These three types of network in contrast with the popular belief that government transparency is interpreted only as a procedural activity to outside parties. A preliminary model in this article gives an overview about the arena of government transparency with multi-directional networks more comprehensively.

Transparent ceramic lamp envelope materials
Energy Technology Data Exchange (ETDEWEB)
Wei, G C [OSRAM SYLVANIA, 71 Cherry Hill Drive, Beverly, MA 01915 (United States)
2005-09-07
Transparent ceramic materials with optical qualities comparable to single crystals of similar compositions have been developed in recent years, as a result of the improved understanding of powder-processing-fabrication- sintering-property inter-relationships. These high-temperature materials with a range of thermal and mechanical properties are candidate envelopes for focused-beam, short-arc lamps containing various fills operating at temperatures higher than quartz. This paper reviews the composition, structure and properties of transparent ceramic lamp envelope materials including sapphire, small-grained polycrystalline alumina, aluminium oxynitride, yttrium aluminate garnet, magnesium aluminate spinel and yttria-lanthana. A satisfactory thermal shock resistance is required for the ceramic tube to withstand the rapid heating and cooling cycles encountered in lamps. Thermophysical properties, along with the geometry, size and thickness of a transparent ceramic tube, are important parameters in the assessment of its resistance to fracture arising from thermal stresses in lamps during service. The corrosive nature of lamp-fill liquid and vapour at high temperatures requires that all lamp components be carefully chosen to meet the target life. The wide range of new transparent ceramics represents flexibility in pushing the limit of envelope materials for improved beamer lamps.

Cultural and musical activity among Norwegian doctors.
Nylenna, Magne; Aasland, Olaf Gjerløw
2013-06-25
The cultural and musical activity of Norwegian doctors was studied in 1993. We wished to re-examine their cultural and musical activity, analyse the development and study the correlation with satisfaction, health and other leisure activities. In the autumn of 2010, a survey was undertaken among a representative sample of economically active Norwegian doctors. The survey asked the same questions as in 1993, and the responses were also compared to the population studies conducted by Statistics Norway. We also used a cultural index that we have developed ourselves. Altogether 1,019 doctors (70%) responded to the survey. They reported a higher level of cultural activity in 2010 than in 1993, measured in terms of reading of non-medical literature and visits to the cinema, theatre and concerts. The doctors engaged in musical activity of their own especially frequently: 58% reported to be able to play an instrument, and 21% reported to play on a regular basis, which is more than among other academic professions. We found a significant correlation between the doctors' level of cultural activity and their job satisfaction, general satisfaction, self-reported health and physical activity. The doctors who engage most frequently in cultural activities are thus most satisfied with their work and with life in general. Furthermore, they also have better self-reported health. Norwegian doctors give priority to cultural and musical activities. The assertion that doctors are particularly fond of music is more than just a myth.

Full Text Available Lobbying transparency seems to have been a challenging topic for nearly a decade. For the purposes of the article, the authors focus on a contextual analysis of rules and measures that offers both a broad as well as comprehensive view of the required transparency of lobbying activities and the environment in which decisions are made. In this regard, focusing on the sunshine principles/sunshine rules (not purely limited to laws provides a grasp of the whole issue in a broader context. From a methodological point of view, the exploratory approach was chosen and the coding procedure is mostly dichotomous. As a result, seven key areas with 70 indicators have been identified in terms of transparency of lobbying and decision-making.
Liquidity and Transparency in Bank Risk Management

Banks may be unable to refinance short-term liabilities in case of solvency concerns. To manage this risk, banks can accumulate a buffer of liquid assets, or strengthen transparency to communicate solvency. While a liquidity buffer provides complete insurance against small shocks, transparency covers also large shocks but imperfectly. Due to leverage, an unregulated bank may choose insufficient liquidity buffers and transparency. The regulatory response is constained: while liquidity buffers ...
Did you hear the one about the doctor? An examination of doctor jokes posted on Facebook.
Davis, Matthew A; Haney, Carol Sue; Weeks, William B; Sirovich, Brenda E; Anthony, Denise L
2014-02-13
Social networking sites such as Facebook have become immensely popular in recent years and present a unique opportunity for researchers to eavesdrop on the collective conversation of current societal issues. We sought to explore doctor-related humor by examining doctor jokes posted on Facebook. We performed a cross-sectional study of 33,326 monitored Facebook users, 263 (0.79%) of whom posted a joke that referenced doctors on their Facebook wall during a 6-month observation period (December 15, 2010 to June 16, 2011). We compared characteristics of so-called jokers to nonjokers and identified the characteristics of jokes that predicted joke success measured by having elicited at least one electronic laugh (eg, an LOL or "laughing out loud") as well as the total number of Facebook "likes" the joke received. Jokers told 156 unique doctor jokes and were the same age as nonjokers but had larger social networks (median Facebook friends 227 vs 132, PFacebook likes (rate ratio [RR] 2.36, 95% CI 0.97-5.74). This study provides insight into the use of social networking sites for research pertaining to health and medicine, including the world of doctor-related humor.

On transparent potentials: a Born approximation study
International Nuclear Information System (INIS)
Coudray, C.
1980-01-01
In the frame of the scattering inverse problem at fixed energy, a class of potentials transparent in Born approximation is obtained. All these potentials are spherically symmetric and are oscillating functions of the reduced radial variable. Amongst them, the Born approximation of the transparent potential of the Newton-Sabatier method is found. In the same class, quasi-transparent potentials are exhibited. Very general features of potentials transparent in Born approximation are then stated. And bounds are given for the exact scattering amplitudes corresponding to most of the potentials previously exhibited. These bounds, obtained at fixed energy, and for large values of the angular momentum, are found to be independent on the energy
Transparent data mining for big and small data
Quercia, Daniele; Pasquale, Frank
2017-01-01
This book focuses on new and emerging data mining solutions that offer a greater level of transparency than existing solutions. Transparent data mining solutions with desirable properties (e.g. effective, fully automatic, scalable) are covered in the book. Experimental findings of transparent solutions are tailored to different domain experts, and experimental metrics for evaluating algorithmic transparency are presented. The book also discusses societal effects of black box vs. transparent approaches to data mining, as well as real-world use cases for these approaches. As algorithms increasingly support different aspects of modern life, a greater level of transparency is sorely needed, not least because discrimination and biases have to be avoided. With contributions from domain experts, this book provides an overview of an emerging area of data mining that has profound societal consequences, and provides the technical background to for readers to contribute to the field or to put existing approaches to prac...

Quantum networks will enable extraordinary capabilities for communicating and processing quantum information. These networks require a reliable means of storage, retrieval, and manipulation of quantum states at the network nodes. A node receives one or more coherent inputs and sends a conditional output to the next cascaded node in the network through a quantum channel. Here, we demonstrate this basic functionality by using the quantum interference mechanism of electromagnetically induced transparency in a transmon qubit coupled to a superconducting resonator. First, we apply a microwave bias, i.e., drive, to the qubit-cavity system to prepare a Λ -type three-level system of polariton states. Second, we input two interchangeable microwave signals, i.e., a probe tone and a control tone, and observe that transmission of the probe tone is conditional upon the presence of the control tone that switches the state of the device with up to 99.73% transmission extinction. Importantly, our electromagnetically induced transparency scheme uses all dipole allowed transitions. We infer high dark state preparation fidelities of >99.39 % and negative group velocities of up to -0.52 ±0.09 km /s based on our data.

Full Text Available Relation of Transparency and Economic growth is a long global debate in the society. Theoretically, policy makers, scholars and researchers argue that there is a close relation among these two variables. However, the quantitative relation and any global model is yet unrevealed. So, the main aim of this paper is to ascertain the nature, dimension and extent of the relationship between economy and Transparency as well as to invent a global model. This paper is useful for researchers, planners, policy makers and scholars who are directly or indirectly involved or willing to involve in the thrust for quantitative relation of these two variables. Literature review is the main source of information of this study. In introductory section, this paper briefly describes theoretical relationship of economy and Transparency as well as it also describes the proxy variables.GDP (2012 of different countries are used as proxy of Economy and Corruption Perception Index (CPI scores (2012 of different countries are used as proxy of level of Transparency. In methodology section this paper describes the detail methodology, sampling procedure and level of analysis. This study randomly selects 30 countries (10 from higher CPI scores+10 from moderate CPI scores+ 10 from lower CPI scores around the globe as sample. In the third section, this research presents the correlation value which divulge that there is a positive correlation (p=.047 with 95% confidence level. That reveals, if the level of transparency of any country increase, the GDP also increase accordingly. Then in this section two quantitative models are developed using linear regression analysis. First invented model is: Economy (GDP in billion US$ = [(8.983*Level of transparency -108.11]. This paper termed the first invented model as “Mahmud EcoT Model-1”. This model calibrates that one unit improvement of transparency leads 8.98 billion US$ improvement in the GDP of a country. Then taking this unit

There is a national and an international trend towards administrative transparency. This trend has not stopped at. the Swiss border. Some cantons of Switzerland have already introduced the transparency principle at the cantonal level. At the federal level, the Swiss Confederation introduced on 1 July 2006 the new Federal 'Freedom of Information Act'. Also the Swiss Federal Nuclear Safety Inspectorate (I-ISK) falls under this rule. Before introduction of this law on transparency. most of the documents of Swiss federal Administration were treated as confidential. Access rights to official documents were granted only on certain conditions and in special cases. But there is a general interest, that the public should have the possibility to ask to look at the files of the administration. Since years, the administration had no longer been able to hide behind secretiveness. For instance, the introduction of Internet brought a lot of transparency. The administration had to explain what sort of job it is actually doing and how it is doing. Also, the media were and are increasing their research for information. In this context, the new law on transparency ('Freedom of Information Act') is rather an evolution than a revolution. The Freedom of Information Act guarantees the public access to official documents. Most of the documents of the Federal Administration are public. This access can be limited, differentiated or refused in certain cases. That means that the principle of proportionality between private interests and public transparency has to be applied. The real challenge for the authority is the trade off between the public's right to access information and the industrial legitimate efforts to protect industrial and trade secrets. In the nuclear field, the international principle of transparency has also become an important national principle for Switzerland and FISK. The Swiss Nuclear Energy Act says that 'The relevant authorities shall regularly inform the general

Although having a regular primary care provider is noted to be beneficial to health, doctor shopping has been documented as a common treatment seeking behavior among chronically ill patients in different countries. However, little research has been conducted into the reasons behind doctor shopping behavior among patients with overactive bladder, and even less into how this behavior relates to these patients' illness and social experiences, perceptions, and cultural practices. Therefore, this study examines overactive bladder patients to investigate the reasons behind doctor shopping behavior. My study takes a qualitative approach, conducting 30 semi-structured individual interviews, with 30 overactive bladder patients in Hong Kong. My study found six primary themes that influenced doctor shopping behavior: lack of perceived need, convenience, work-provided medical insurance, unpleasant experiences with doctors, searching for a match doctor, and switching between biomedicine and traditional Chinese medicine. Besides the perceptual factors, participants' social environment, illness experiences, personal cultural preference, and cultural beliefs also intertwined to generate their doctor shopping behavior. Due to the low perceived need for a regular personal primary care physician, environmental factors such as time, locational convenience, and work-provided medical insurance became decisive in doctor shopping behavior. Patients' unpleasant illness experiences, stemming from a lack of understanding among many primary care doctors about overactive bladder, contributed to participants' sense of mismatch with these doctors, which induced them to shop for another doctor. Overactive bladder is a chronic bladder condition with very limited treatment outcome. Although patients with overactive bladder often require specialty urology treatment, it is usually beneficial for the patients to receive continuous, coordinated, comprehensive, and patient-centered support from their
Local probing by use of transparent model materials
Philippe, P.
2017-12-01
The present contribution emphasizes on two distinct examples the benefit with using transparent materials that enable direct visualization within different types of model systems. Our first use of transparent materials investigates the elementary mechanisms involved in soil erosion based on three key ingredients: a) cohesive model materials (i.e. glass beads bonded by solid bridges); b) optical techniques (Refractive Index Matching and Planar Laser Induced Fluorescence [1,2]) ; c) specific mechanical tests to estimate the mechanical strength of the solid bonds. Then, critical shear-stress at erosion onset can be related to tensile strength considering an extension of the classical Shields' number [3,4].Our second example uses a transparent elasto-visco-plastic fluid (Carbopol) as a model of debris flows. Different geometrical configurations allow for an accurate investigation of the flow over an obstacle [5] or a cavity [6], inducing the existence of a dead-zone and consequently of a frontier between solid-like and fluid-like regions that is of particular relevance for debris flows mobilization and deposition. Practically, the hydrodynamics of the flow is investigated by means of high-resolution optical velocimetry (PIV) and underlines a non-monotonous evolution of the shear rate, which increases from zero at the solid-liquid interface, passes through a peak (sometimes leveling off at its maximum value), and returns to zero in a plug zone sufficiently far above the cavity or the obstacle.

Transparency of nuclear regulatory activities
International Nuclear Information System (INIS)
2007-01-01
One of the main missions of nuclear regulators is to protect the public, and this cannot be completely achieved without public confidence. The more a regulatory process is transparent, the more such confidence will grow. Despite important cultural differences across countries, a number of common features characterise media and public expectations regarding any activity with an associated risk. A common understanding of transparency and main stakeholders' expectations in the field of nuclear safety were identified during this workshop, together with a number of conditions and practices aimed at improving the transparency of nuclear regulatory activities. These conditions and practices are described herein, and will be of particular interest to all those working in the nuclear regulatory field. Their implementation may, however, differ from one country to another depending on national context. (authors)
Examining A Health Care Price Transparency Tool: Who Uses It, And How They Shop For Care.
Sinaiko, Anna D; Rosenthal, Meredith B
2016-04-01
Calls for transparency in health care prices are increasing, in an effort to encourage and enable patients to make value-based decisions. Yet there is very little evidence of whether and how patients use health care price transparency tools. We evaluated the experiences, in the period 2011-12, of an insured population of nonelderly adults with Aetna's Member Payment Estimator, a web-based tool that provides real-time, personalized, episode-level price estimates. Overall, use of the tool increased during the study period but remained low. Nonetheless, for some procedures the number of people searching for prices of services (called searchers) was high relative to the number of people who received the service (called patients). Among Aetna patients who had an imaging service, childbirth, or one of several outpatient procedures, searchers for price information were significantly more likely to be younger and healthier and to have incurred higher annual deductible spending than patients who did not search for price information. A campaign to deliver price information to consumers may be important to increase patients' engagement with price transparency tools. Project HOPE—The People-to-People Health Foundation, Inc.

Full Text Available Transparent antennas have been continuously developed for integration with solar cells, vehicular communications, and ultra-high-speed communications such as 5G in recent years. A transparent antenna takes advantage of spatial extensibility more so than all other antennas in terms of wide range of usable area. In addition, the production price of transparent antennas is steadily decreasing due to the development of nano-process technology. This paper reviews published studies of transparent antennas classified by various materials in terms of optical transmittance and electrical, sheet resistance. The transparent electrodes for the transparent antenna are logically classified and the transparent antennas are described according to the characteristics of each electrode. Finally, the contributions transparent antennas can make toward next-generation 5G high-speed communication are discussed.

Graphene Transparent Conductive Electrodes for Next- Generation Microshutter Arrays
Li, Mary; Sultana, Mahmooda; Hess, Larry
2012-01-01
Graphene is a single atomic layer of graphite. It is optically transparent and has high electron mobility, and thus has great potential to make transparent conductive electrodes. This invention contributes towards the development of graphene transparent conductive electrodes for next-generation microshutter arrays. The original design for the electrodes of the next generation of microshutters uses indium-tin-oxide (ITO) as the electrode material. ITO is widely used in NASA flight missions. The optical transparency of ITO is limited, and the material is brittle. Also, ITO has been getting more expensive in recent years. The objective of the invention is to develop a graphene transparent conductive electrode that will replace ITO. An exfoliation procedure was developed to make graphene out of graphite crystals. In addition, large areas of single-layer graphene were produced using low-pressure chemical vapor deposition (LPCVD) with high optical transparency. A special graphene transport procedure was developed for transferring graphene from copper substrates to arbitrary substrates. The concept is to grow large-size graphene sheets using the LPCVD system through chemical reaction, transfer the graphene film to a substrate, dope graphene to reduce the sheet resistance, and pattern the film to the dimension of the electrodes in the microshutter array. Graphene transparent conductive electrodes are expected to have a transparency of 97.7%. This covers the electromagnetic spectrum from UV to IR. In comparison, ITO electrodes currently used in microshutter arrays have 85% transparency in mid-IR, and suffer from dramatic transparency drop at a wavelength of near-IR or shorter. Thus, graphene also has potential application as transparent conductive electrodes for Schottky photodiodes in the UV region.

High specific-capacity pseudocapacitive transition-metal-hydroxide (TMH) materials are desirable for future high performance transparent supercapacitors, but have been rarely reported previously. The successful synthesis of TMH materials with desired nanostructures is a key factor for their transparency. Here, Ni(OH) 2 nanosheet transparent film (NNS-TF) was developed simply through a gas-liquid diffusion method. The nanostructures were enwrapped in graphene shells (NNS@Gr-TF) for using as transparent electrodes. The unique encapsulation structures build up rapid three-dimensional electron and ion transport pathways together with the underlying ITO layer. The specific areal capacitance (18.9 mF/cm 2 at 0.1 mA/cm 2 ) was greatly improved, at least a thousand times higher than the reported value for transparent devices based on planer CVD graphene, and ten times as that for 3D micro-structured graphene membrane.

Full Text Available In modern society, in terms of general information and integration of the economies, information is one of the main market products. There is becoming urgent task of improving financial statement transparency for enterprises in this situation. One of the most challenging in improving transparency can be considered the construction industry, because of the pursuit of privacy and a high degree of corruption. The paper analyzes the possible reasons for reducing the level of transparency in the construction industry companies. The paper highlighted the general and particular causes that affect the transparency of financial reporting of construction enterprises. Common causes are relevant for companies in any industry, and private causes show features characteristic of the construction itself. In addition, the paper analyzes the various methods of increasing the transparency used by companies all over the world. The analysis highlighted the internal and external methods for improving the transparency of financial statements and transparency of construction companies. Leadership and employees at the enterprise level providing transparency of financial reporting, and non-financial information about the company, having interest to stakeholders, carry out internal methods. External methods are applied at the macro level as the joint forces of the enterprises of the construction industry to form associations and the state. The analysis also considered the possibility of using these methods by the Russian construction companies and advantages and disadvantages of their application.
Doctor and pharmacy shopping for controlled substances.

Prescription drug abuse is a major health concern nationwide, with West Virginia having one of the highest prescription drug death rates in the United States. Studies are lacking that compare living subjects with persons who died from drug overdose for evidence of doctor and pharmacy shopping for controlled substances. The study objectives were to compare deceased and living subjects in West Virginia for evidence of prior doctor and pharmacy shopping for controlled substances and to identify factors associated with drug-related death. A secondary data study was conducted using controlled substance, Schedule II-IV, prescription data from the West Virginia Controlled Substance Monitoring Program and drug-related death data compiled by the Forensic Drug Database between July 2005 and December 2007. A case-control design compared deceased subjects 18 years and older whose death was drug related with living subjects for prior doctor and pharmacy shopping. Logistic regression identified factors related to the odds of drug-related death. A significantly greater proportion of deceased subjects were doctor shoppers (25.21% vs. 3.58%) and pharmacy shoppers (17.48% vs. 1.30%) than living subjects. Approximately 20.23% of doctor shoppers were also pharmacy shoppers, and 55.60% of pharmacy shoppers were doctor shoppers. Younger age, greater number of prescriptions dispensed, exposure to opioids and benzodiazepines, and doctor and pharmacy shopping were factors with greater odds of drug-related death. Doctor and pharmacy shopping involving controlled substances were identified, and shopping behavior was associated with drug-related death. Prescription monitoring programs may be useful in identifying potential shoppers at the point of care.

This report marks the end of the PSO funded R and D project PowerShades. The objective of the project has been to establish knowledge about the manufacturing of PowerShade transparent photovoltaics and to demonstrate the viability of PowerShade, both as a product and when considered a building element. It has not been the objective to demonstrate a full-scale manufacturing of PowerShade, but to establish the knowledge that enables industrial manufacturing. The overall objective of the project has been achieved, and the large majority of the milestones defined have been met to full extent. It has been shown that PowerShade photovoltaic cells with an electrical efficiency of 5% can be reached, and it is expected that future work will lead to even better efficiency. Also, it has been demonstrated by full size side by side comparison that PowerShade transparent photovoltaics may replace exterior solar shading devices without compromise to the thermal properties of the building. The project has identified a number of work areas that must be addressed before an industrial manufacturing can be established. The efficiency of the photovoltaic generator must be increased and the stability of the entire product documented. Also, some of the identified processing steps must be scaled in capacity before manufacturing can be considered. (author)

The increasingly popular term transparency has been used throughout the IAEA Safeguards Symposium to mean many things to many people. It has rather little utility as a catch-all term or buzz word. A precise definition of transparency is in order. In this paper, transparency is the provision to the IAEA of additional information for which the IAEA has an identified use and includes any associated increased IAEA access to sue the information. In 1993, the IAEA Board endorsed very specific proposals for provision to the IAEA of additional information on international nuclear transfers. It also made specific decisions on verification in the context of tis earlier confirmation of the very sweeping access rights for special inspections outlined by the director general. Additional information to the IAEA has two potential practical uses. First, it could help identify inconsistencies within the entirety of the information available to the IAEA, including information from inspections. These inconsistencies could be an indication of some violation of safeguards undertakings. Second, a declaration of the Member State could facilitate IAEA interpretation of analyses of other information or facilitate resolution of ambiguities. In these respects, additional information is not different from currently used information. When considering seeking specific additional information, the IAEA must balance the potential contribution of the information and its expected costs

Only a patient and his or her family can judge many of the most important aspects of the doctor-patient interaction. This study evaluates the feasibility and reliability of children and their families assessing the quality of paediatricians' interactions using a rating instrument developed specifically for this purpose. A reliability analysis using generalisability theory on the ratings from 352 doctor-patient interactions across different speciality clinics. Ratings were normally distributed. They were highest for 'overall' performance, and lowest for giving time to discuss the families' agenda. An appropriate sample of adults' ratings provided a reliable score (G = 0.7 with 15 raters), but children's ratings were too idiosyncratic to be reproducible (G = 0.36 with 15 raters). CONCLUSIONS AND FURTHER WORK: Accompanying adults can provide reliable ratings of doctors' interactions with children. Because an adult is usually present at the consultation their ratings provide a highly feasible and authentic approach. Sampling doctors' interactions from different clinics and with patients of both genders provides a universal picture of performance. The method is ideal to measure performance for in-training assessment or revalidation. Further work is in progress to evaluate the educational impact of feeding ratings back to the doctors being assessed, and their use in a range of clinical contexts.

Full Text Available Abstract Background Unattached patients do not have a regular primary care provider. Initiatives are being developed to increase attachment rates across Canada. Most existing attention paid to patient unattachment has focused on quantifying the problem and health system costs. Our purpose is to qualitatively identify the implications of chronically ill patients’ experiences of unattachment for health policy and planning to provide policy-relevant insights for Canadian attachment initiatives. Methods Three focus groups were conducted with marginalized chronically ill individuals residing in a mid-sized city in British Columbia who are unattached to a family doctor. We use the term marginalized as a descriptor to acknowledge that by virtue of their low socio-economic status and lack of attachment the participants are marginalized in Canada’s health care system Focus groups were structured as an open conversation organized around a series of probing questions. They were digitally recorded and transcribed verbatim. Thematic analysis was employed. Results Twenty-six individuals participated in the focus groups. The most common chronic illnesses reported were active drug addiction or recovery (and their associated symptoms, depression, arthritis, and hepatitis C. Participants identified life transitions as being the root cause for not having a family doctor. There was a strong sense that unsuccessful attempts to get a family doctor reflected that they were undesirable patients. Participants wanted to experience having a trusting relationship with a regular family doctor as they believed it would encourage greater honesty and transparency. One of the main health concerns regarding lack of access to a regular family doctor is that participants lacked access to preventative care. Participants were also concerned about having a discontinuous medical record due to unattachment. Conclusions Participants perceived that there are many benefits to be had

However, is consideration always extended to the patient’s perception of the use of smartphones by doctors? Do patients know why we use smartphones to assist us in their care? What do they think when they see a doctor using a smartphone?An independent question, conducted within a wider service evaluation (ethical approval not required, full verbal and written electronic consent provided by all patients at St. Mary’s Hospital, London, indicated that although the majority (91.0% of patients owned a smartphone, many (61.6% did not agree that the use of smartphones at work by doctors is professional. This highlights the potential for damage to the doctor–patient relationship. There is a risk that these patients will disconnect with care services with possible detriment to their health. Additionally, it is notable that a larger proportion of those patients aged >70 years found the use of smartphones by doctors at work unprofessional, compared with patients aged <70 years.Adequate communication between the doctor and patient is critical in ensuring that doctors can make use of modern technology to provide the best possible care and that patients are comfortable with this and do not feel isolated or

This paper addresses price transparency on the consumer side in markets with behavioral price discrimination which feature welfare reducing brand switching. When long-term contracts are not available, an increase in transparency intensifies competition, lowers prices and profits, reduces brand...... switching and benefits consumers and welfare. With long-term contracts, an increase in transparency reduces the use of long-term contracts, leading to more brand switching and a welfare loss. Otherwise, the results are the same as without long-term contracts....

Determining factors that affect healthcare utilization by the elderly is vital for the health system to be more responsive in providing care to this vulnerable group. The main objective of this paper is to identify the effect of the predisposing, enabling, and need factors on doctor visits and in-patient care for the elderly residing in the northern region of Malaysia. A multistage cluster sampling was used in selecting the sample for the study. A total of 1414 respondents aged 60 and over were interviewed face-to-face using a structured questionnaire. A probit model was used in estimating the utilization equations. At a significance level of 0.05, except for age, all predisposing and enabling factors were not statistically significant in affecting the doctor visits. On the other hand, being a male, smoker, medical insurance holder or had not actively involved in social interaction within the reference period increases the likelihood of being in-patient. Health-related variables remain the most significant factors that determine healthcare utilization, including both doctor visits and in-patient stays, in the area of study, which suggests that government policies to improve population health may influence the level of healthcare use in the future.

Plasmon induced transparency (PIT) could be realized in metamaterials via interference between different resonance modes. Within the sharp transparency window, the high dispersion of the medium may lead to remarkable slow light phenomena and an enhanced nonlinear effect. However, the transparency mode is normally localized in a narrow frequency band, which thus restricts many of its applications. Here we present the simulation, implementation, and measurement of a broadband PIT metamaterial functioning in the terahertz regime. By integrating four U-shape resonators around a central bar resonator, a broad transparency window across a frequency range greater than 0.40 THz is obtained, with a central resonance frequency located at 1.01 THz. Such PIT metamaterials are promising candidates for designing slow light devices, highly sensitive sensors, and nonlinear elements operating over a broad frequency range. (paper)

Full Text Available Purpose: In current economy, where ICT plays a crucial role for being competitive and effective, businesses are facing higher pressures of flexibility and efficiency than ever before. Transparency is often considered as a suitable mechanism for better market prices and more efficient market environment. Electronic business environment provides the possibility to set up more transparent environment and bring higher competitiveness and efficiency on the market. The paper analyse the impact of transparency on prices in e-procurement.Methodology: Reverse auctions are considered as transparent tool simulating in partial level real competition. Together, it allows to examine several levels of transparency set up in auction negotiation process. The impact of transparency on final prices was analysed on real data using relation based analysis were different situations of transparency set up is compared against achieved final price.Findings: Research results based on real data shows, that generally, the transparency in electronic reverse auction can lead to more negative prices agreed by purchasers as current scientific and commercial promotions.Research limitation: Significance of research results is limited due to still low readiness and skills of e-procurers. The validation of results is needed to realized within longer period of time and from environments with different level of e-readiness. Together, it reveal that transparency is more complex issue where the significance of transparency can reveal its sense in some specific situations on the market and negotiation.Value of paper: Evidenced based research reveal some controversy results which support new scientific efforts in microeconomics and socio-economic impact of ICT fields. Together, it affects real practitioners in way how to use and perceive claimed impact of reverse auction solutions.

Overview of Russian HEU transparency issues

Kempf, C.R.; Bieniawski, A.
1993-01-01
The U.S. has signed an agreement with the Russian Federation for the purchase of 500 metric tons of highly-enriched uranium (HEU) taken from dismantled nuclear weapons. The HEU will be blended down to low-enriched uranium and will be transported to the U.S. to be used by fuel fabricators to make fuel for commercial nuclear power plants. Both the U.S. and Russia have been preparing to institute transparency measures to provide assurance that nonproliferation and arms control objectives specified in the agreement are met. This paper provides background information on the original agreement and on subsequent negotiations with the Russians, as well as discussion of technical aspects of developing transparency measures suited to the facilities and processes which are expected to be involved. Transparency has been defined as those agreed-upon measures which build confidence that arms control and non-proliferation objectives shared by the parties are met. Transparency is a departure from exhaustive, detailed arms control verification regimes of past agreements, which were based on a presumption of detecting transgressions as opposed to confirming compliance

Optimal Degrees of Transparency in Monetary Policymaking
DEFF Research Database (Denmark)
Jensen, Henrik
2002-01-01
According to most academics and policymakers, transparency in monetary policymaking is desirable. I examine this proposition in a small theoretical model emphasizing forward-looking private sector behavior. Transparency makes it easier for price setters to infer the central bank's future policy...... intentions, thereby making current inflation more responsive to policy actions. This induces the central bank to pay more attention to inflation rather than output gap stabilization. Then, transparency may be disadvantageous. It may actually be a policy-distorting straitjacket if the central bank enjoys low...

A SnO 2 transparent thin-film transistor (TTFT) is demonstrated. The SnO 2 channel layer is deposited by RF magnetron sputtering and then rapid thermal annealed in O 2 at 600 deg. C. The TTFT is highly transparent, and enhancement-mode behaviour is achieved by employing a very thin channel layer (10-20 nm). Maximum field-effect mobilities of 0.8 cm 2 V -1 s -1 and 2.0 cm 2 V -1 s -1 are obtained for enhancement- and depletion-mode devices, respectively. The transparent nature and the large drain current on-to-off ratio of 10 5 associated with the enhancement-mode behaviour of these devices may prove useful for novel gas-sensor applications

Burnout and Doctors: Prevalence, Prevention and Intervention
Kumar, Shailesh
2016-01-01
Doctors are exposed to high levels of stress in the course of their profession and are particularly susceptible to experiencing burnout. Burnout has far-reaching implications on doctors; patients and the healthcare system. Doctors experiencing burnout are reported to be at a higher risk of making poor decisions; display hostile attitude toward patients; make more medical errors; and have difficult relationships with co-workers. Burnout among doctors also increases risk of depression; anxiety; sleep disturbances; fatigue; alcohol and drug misuse; marital dysfunction; premature retirement and perhaps most seriously suicide. Sources of stress in medical practice may range from the emotions arising in the context of patient care to the environment in which doctors practice. The extent of burnout may vary depending on the practice setting; speciality and changing work environment. Understanding dynamic risk factors associated with burnout may help us develop strategies for preventing and treating burnout. Some of these strategies will be reviewed in this paper. PMID:27417625

In contemporary U.S. doctor's series, the characters are usually represented by good-looking or typical character actors. The aim of our pilot study was to investigate whether the long-term impact of this format on German television viewers could have an influence on the choice of doctor in Germany. Two different groups of people anticipating TV consumption patterns were questioned: a first group of younger adults who knew theTV series was asked to judge their doctor choice using a web-based survey tool with respect to three criteria (sympathy, expertise and own treatment preference). The second group of adults beyond the 40th year of life who need not know theTV series were shown photos of the serial figures. Study participants should select the "doctor" of which they would most likely want to be treated and this based on two predetermined reasons (sympathy or expertise). Our results indicate that stereotypical images of doctors found high approval only in the first group of people, while the participants in the second group decided in majorityfora more realistic representation of average appearance.

This study aimed to evaluate the nature and type of communication and workflow arrangements between nurses and doctors out-of-hours (OOH). Effective communication and workflow arrangements between nurses and doctors are essential to minimize risk in hospital settings, particularly in the out-of-hour's period. Timely patient flow is a priority for all healthcare organizations and the quality of communication and workflow arrangements influences patient safety. Qualitative descriptive design and data collection methods included focus groups and individual interviews. A 500 bed tertiary referral acute hospital in Ireland. Junior and senior Non-Consultant Hospital Doctors, staff nurses and nurse managers. Both nurses and doctors acknowledged the importance of good interdisciplinary communication and collaborative working, in sustaining effective workflow and enabling a supportive working environment and patient safety. Indeed, issues of safety and missed care OOH were found to be primarily due to difficulties of communication and workflow. Medical workflow OOH is often dependent on cues and communication to/from nursing. However, communication systems and, in particular the bleep system, considered central to the process of communication between doctors and nurses OOH, can contribute to workflow challenges and increased staff stress. It was reported as commonplace for routine work, that should be completed during normal hours, to fall into OOH when resources were most limited, further compounding risk to patient safety. Enhancement of communication strategies between nurses and doctors has the potential to remove barriers to effective decision-making and patient flow. © The Author 2017.

Commercial production of transparent conducting oxide (TCO) polycrystalline films requires high electrical conductivity with minimal degradation in optical transparency. Aqueous solution deposited TCO films would reduce production costs of TCO films but suffer from low electrical mobility, which severely degrades both electrical conductivity and optical transparency in the visible spectrum. Here, we demonstrated that grain boundary modification by ultra-violet laser crystallization (UVLC) of solution deposited aluminium-doped zinc oxide (AZO) nanocrystals results in high Hall mobility, with a corresponding dramatic improvement in AZO electrical conductance. The AZO films after laser irradiation exhibit electrical mobility up to 18.1 cm{sup 2} V{sup −1} s{sup −1} with corresponding electrical resistivity and sheet resistances as low as 1 × 10{sup −3} Ω cm and 75 Ω/sq, respectively. The high mobility also enabled a high transmittance (T) of 88%-96% at 550 nm for the UVLC films. In addition, HAZE measurement shows AZO film scattering transmittance as low as 1.8%, which is superior over most other solution deposited transparent electrode alternatives such as silver nanowires. Thus, AZO films produced by the UVLC technique have a combined figure of merit for electrical conductivity, optical transparency, and optical HAZE higher than other solution based deposition techniques and comparable to vacuumed based deposition methods.

Assessment of the Climate Paris Agreement in the light of a Global Standard of Transparency
International Nuclear Information System (INIS)
Tabau, Anne-Sophie
2016-01-01
Reactions to the Paris Agreement oscillate between political enthusiasm, given the diplomatic challenge that was taken-up, and activist disappointment, considering the emergency and scale of transformations to undertake to tackle climate change. The legal analysis of the COP21, its results and prospects they open however needs to be done in the light of dispassionate criteria. The one proposed in this paper uses a global standard of transparency. The reading grid offered thus enables to locate the Paris Agreement in the context of a global and complex governance; two features that the theory of global administrative law aims to better understand, from an empirical but also a prescriptive approaches. This assessment shows that the balance between transparency and opacity, intelligibility, effectiveness or efficiency is both delicate to establish and unstable. If the way the cursor was positioned under the Paris Agreement may seem unsatisfactory in many respects, it must not be forgotten that it is intended to evolve

Promoting Interdisciplinary Education: The Vienna Doctoral Programme on Water Resource Systems
Blöschl, Günter; Bucher, Christian; Carr, Gemma; Farnleitner, Andreas; Rechberger, Helmut; Wagner, Wolfgang; Zessner, Matthias
2010-05-01
An interdisciplinary approach is often described as a valuable strategy to assist in overcoming the existing and emerging challenges to water resource management. The development of educational approaches to instil a culture of interdisciplinarity in the future generation of water resource professionals will help to meet this strategic need. The Vienna Doctoral Programme on Water Resource Systems demonstrates how the adoption of an interdisciplinary education framework has been applied to a graduate programme in the water sciences. The interdisciplinary approach aims to provide doctoral research students with an understanding of the wide spectrum of processes relevant to water resource systems. This will enable them to bring together a range of ideas, strategies and methods to their current research and future careers. The education programme also aims to teach the softer skills required for successful interdisciplinary work such as the ability to communicate clearly with non-specialist professionals and the capacity to listen to and accommodate suggestions from experts in different disciplines, which have often not traditionally been grouped together. The Vienna Doctoral Programme achieves these aims through teaching an appreciation for a wide variety of approaches including laboratory analysis, field studies and numerical methods across the fields of hydrology, remote sensing, hydrogeology, structural mechanics, microbiology, water quality and resource management. Teaching takes the form of a detailed study programme on topics such as socio-economic concepts, resource and river basin management, modelling and simulation methods, health related water quality targets, urban water management, spatial data from remote sensing and basics for stochastic mechanics. Courses are also held by internationally recognised top scientists, and a guest scientist seminar series allows doctoral researchers to profit from the expertise of senior researchers from around the world

A digital signal process enabled dual-drive Mach-Zehnder modulator (DD-MZM)-based spectral converter is proposed and extensively investigated to realize dynamically reconfigurable and high transparent spectral conversion. As another important innovation point of the paper, to optimize the converter performance, the optimum operation conditions of the proposed converter are deduced, statistically simulated, and experimentally verified. The optimum conditions supported-converter performances are verified by detail numerical simulations and experiments in intensity-modulation and direct-detection-based network in terms of frequency detuning range-dependent conversion efficiency, strict operation transparency for user signal characteristics, impact of parasitic components on the conversion performance, as well as the converted component waveform are almost nondistortion. It is also found that the converter has the high robustness to the input signal power, optical signal-to-noise ratio variations, extinction ratio, and driving signal frequency.

2017-01-01
This paper presents the analysis of 28GHz solar patch antenna using the variations of transparent conductive oxides (TCO) thin film as the radiating patch. Solar antenna is basically combining the function of antenna and solar cell into one device and helps to maximize the usage of surface area. The main problem of the existing solar antenna is the radiating patch which made of nontransparent material, such as copper, shadowing the solar cell and degrades the total solar efficiency. Hence, by using the transparent conductive oxides (TCO) thin film as the radiating patch, this problem can be tackled. The TCO thin film used is varied to ITO, FTO, AgHT-4, and AgHT-8 along with glass as substrate. The simulation of the antenna executed by using Computer Simulation Technology (CST) Microwave Studio software demonstrated at 28 GHz operating frequency for 5G band applications. The performance of the transparent antennas is compared with each other and also with the nontransparent patch antenna that using Rogers RT5880 as substrate, operating at the same resonance frequency and then, the material that gives the best performance is identified.

Transparent Memory For Harsh Electronics
Ho, C. H.
2017-03-14
As a new class of non-volatile memory, resistive random access memory (RRAM) offers not only superior electronic characteristics, but also advanced functionalities, such as transparency and radiation hardness. However, the environmental tolerance of RRAM is material-dependent, and therefore the materials used must be chosen carefully in order to avoid instabilities and performance degradation caused by the detrimental effects arising from environmental gases and ionizing radiation. In this work, we demonstrate that AlN-based RRAM displays excellent performance and environmental stability, with no significant degradation to the resistance ratio over a 100-cycle endurance test. Moreover, transparent RRAM (TRRAM) based on AlN also performs reliably under four different harsh environmental conditions and 2 MeV proton irradiation fluences, ranging from 1011 to 1015 cm-2. These findings not only provide a guideline for TRRAM design, but also demonstrate the promising applicability of AlN TRRAM for future transparent harsh electronics.
Limits of transparency of transparent conducting oxides
Peelaers, Hartwin
A fundamental understanding of the factors that limit transparency in transparent conducting oxides (TCOs) is essential for further progress in materials and applications. These materials have a sufficiently large band gap, so that direct optical transitions do not lead to absorption of light within the visible spectrum. Since the presence of free carriers is essential for conductivity and thus for device applications, this introduces the possibility of additional absorption processes. In particular, indirect processes are possible, and these will constitute a fundamental limit of the material. The Drude theory is widely used to describe free-carrier absorption, but it is phenomenological in nature and tends to work poorly at shorter wavelengths, where band-structure effects are important. We will present calculations of phonon- and defect-assisted free-carrier absorption in a TCO completely from first principles. We will focus in detail on SnO2, but the methodology is general and we will also compare the results obtained for other TCO materials such as In2O3. These calculations provide not just quantitative results but also deeper insights in the mechanisms that govern absorption processes, which is essential for engineering improved materials to be used in more efficient devices. This work was performed in collaboration with E. Kioupakis and C.G. Van de Walle and was supported by ARO and NSF.

By simply mixing silica nanoparticles (SiNPs), polydimethylsiloxane (PDMS) and heptane to form a suspension, dip- or drop-coating the suspension onto different surfaces, transparent SHP surfaces can be obtained. By tuning the ratio of the three components above, transparency of the coating can reach more than 90% transmittance in the visible region, while static water contact angle of the coating can reach as high as 162°. Dynamic contact angle study shows the advancing contact angle and receding contact angle of water can be as high as 168° and 161°, and the resulting contact angle hysteresis can be as low as 7°. The reported facile way of fabricating transparent superhydrophobic (SHP) surfaces is potential for applications which need both optical transparency and self-cleaning capability, such as solar cells, optical equipment, and visible microfluidic chips.
Interplay between transparency and efficiency in dye sensitized solar cells.
Tagliaferro, Roberto; Colonna, Daniele; Brown, Thomas M; Reale, Andrea; Di Carlo, Aldo
2013-02-11
In this paper we analyze the interplay between transparency and efficiency in dye sensitized solar cells by varying fabrication parameters such as the thickness of the nano-crystalline TiO(2) layer, the dye loading and the dye type. Both transparency and efficiency show a saturation trend when plotted versus dye loading. By introducing the transparency-efficiency plot, we show that the relation between transparency and efficiency is linear and is almost independent on the TiO(2) thickness for a certain thickness range. On the contrary, the relation between transparency and efficiency depends strongly on the type of the dye. Moreover, we show that co-sensitization techniques can be effectively used to access regions of the transparency-efficiency space that are forbidden for single dye sensitization. The relation found between transparency and efficiency (T&E) can be the general guide for optimization of Dye Solar Cells in building integration applications.
Brightness and transparency in the early visual cortex.
Salmela, Viljami R; Vanni, Simo
2013-06-24
Several psychophysical studies have shown that transparency can have drastic effects on brightness and lightness. However, the neural processes generating these effects have remained unresolved. Several lines of evidence suggest that the early visual cortex is important for brightness perception. While single cell recordings suggest that surface brightness is represented in the primary visual cortex, the results of functional magnetic resonance imaging (fMRI) studies have been discrepant. In addition, the location of the neural representation of transparency is not yet known. We investigated whether the fMRI responses in areas V1, V2, and V3 correlate with brightness and transparency. To dissociate the blood oxygen level-dependent (BOLD) response to brightness from the response to local border contrast and mean luminance, we used variants of White's brightness illusion, both opaque and transparent, in which luminance increments and decrements cancel each other out. The stimuli consisted of a target surface and a surround. The surround luminance was always sinusoidally modulated at 0.5 Hz to induce brightness modulation to the target. The target luminance was constant or modulated in counterphase to null brightness modulation. The mean signal changes were calculated from the voxels in V1, V2, and V3 corresponding to the retinotopic location of the target surface. The BOLD responses were significantly stronger for modulating brightness than for stimuli with constant brightness. In addition, the responses were stronger for transparent than for opaque stimuli, but there was more individual variation. No interaction between brightness and transparency was found. The results show that the early visual areas V1-V3 are sensitive to surface brightness and transparency and suggest that brightness and transparency are represented separately.
Contour junctions defined by dynamic image deformations enhance perceptual transparency.
Kawabe, Takahiro; Nishida, Shin'ya
2017-11-01
The majority of work on the perception of transparency has focused on static images with luminance-defined contour junctions, but recent work has shown that dynamic image sequences with dynamic image deformations also provide information about transparency. The present study demonstrates that when part of a static image is dynamically deformed, contour junctions at which deforming and nondeforming contours are connected facilitate the deformation-based perception of a transparent layer. We found that the impression of a transparent layer was stronger when a dynamically deforming area was adjacent to static nondeforming areas than when presented alone. When contour junctions were not formed at the dynamic-static boundaries, however, the impression of a transparent layer was not facilitated by the presence of static surrounding areas. The effect of the deformation-defined junctions was attenuated when the spatial pattern of luminance contrast at the junctions was inconsistent with the perceived transparency related to luminance contrast, while the effect did not change when the spatial luminance pattern was consistent with it. In addition, the results showed that contour completions across the junctions were required for the perception of a transparent layer. These results indicate that deformation-defined junctions that involve contour completion between deforming and nondeforming regions enhance the perception of a transparent layer, and that the deformation-based perceptual transparency can be promoted by the simultaneous presence of appropriately configured luminance and contrast-other features that can also by themselves produce the sensation of perceiving transparency.

[Bertha Röntgen or the transparency of the hand].
Picard, J D
1996-01-01
It is to Wilhelm Conrad Röntgen, the first elected "radiologist" of our Academy and the first Nobel Prize winner in physics, that we owe the transparency of the hand. We celebrate today the centenary of the great scientific discovery which was to revolutionize the diagnosis, and thereby the treatment, of a large number of illnesses the discovery of X-rays. It would be unjust not to link the name of this scientist with that of his wife, Bertha, who, ignorant of the dangers of all "novel medical inventions" volunteered her own hand for his research experiments: the hand which was to bring to the world tangible proof of this remarkable discovery. To a lesser degree, but nonetheless essential, we acknowledge, albeit not in exhaustive detail, all the progress made by the work of pioneers using this new investigative technique. So let us now return to the hand:--a body part which it was easy to immobilize, remembering that in those days a single radiographic exposure took up to an hour to obtain,--we will consider the immortalised hand of Bertha Röntgen,---to whom this address is dedicated,---and its radiographic exposures which allow us to appreciate the advances and to perceive the limitations of this technique. They also enable us better to envisage future investigative approaches whereby a deeper knowledge of the human body may be acquired. We note that compared with the histopathological sciences, imaging is not specific. Numerous microscopic structures, in particular neurological and vascular ones, are still insufficiently well visualised and the transmission pathways between the hand and the central nervous system deserve better characterisation. Current, research programmes are attempting to overcome these limitation of modern imaging. All the experience gained in studying the transparency of the hand, as we have discussed, is applicable to every part of the human anatomy. To credit: Röntgen's discovery with all its originality, we could say that the hand was
Transparency in Canadian public drug advisory committees.
Rosenberg-Yunger, Zahava R S; Bayoumi, Ahmed M
2014-11-01
Transparency in health care resource allocation decisions is a criterion of a fair process. We used qualitative methods to explore transparency across 11 Canadian drug advisory committees. We developed seven criteria to assess transparency (disclosure of members' names, disclosure of membership selection criteria, disclosure of conflict of interest guidelines and members' conflicts, public posting of decisions not to fund drugs, public posting of rationales for decisions, stakeholder input, and presence of an appeals mechanism) and two sub-criteria for when rationales were posted (direct website link and readability). We interviewed a purposeful sample of key informants who were conversant in English and a current or past member of either a committee or a stakeholder group. We analyzed data using a thematic approach. Interviewing continued until saturation was reached. We examined documents from 10 committees and conducted 27 interviews. The median number of criteria addressed by committees was 2 (range 0-6). Major interview themes included addressing: (1) accessibility issues, including stakeholders' degree of access to the decision making process and appeal mechanisms; (2) communication issues, including improving internal and external communication and public access to information; and (3) confidentiality issues, including the use of proprietary evidence. Most committees have some mechanisms to address transparency but none had a fully transparent process. The most important ways to improve transparency include creating formal appeal mechanisms, improving communication, and establishing consistent rules about the use of, and public access to, proprietary evidence.

Full Text Available Aim/Purpose: The purpose of the current study is to explore student perceptions of their own doctoral-level education and quantitative proficiency. Background: The challenges of preparing doctoral students in education have been discussed in the literature, but largely from the perspective of university faculty and program administrators. The current study directly explores the student voice on this issue. Methodology: Utilizing a sequential explanatory mixed-methods research design, the present study seeks to better understand doctoral-level education students’ perceptions of their quantitative methods training at a large public university in the southwestern United States. Findings: Results from both phases present the need for more application and consistency in doctoral-level quantitative courses. Additionally, there was a consistent theme of internal motivation in the responses, suggesting students perceive their quantitative training to be valuable beyond their personal interest in the topic. Recommendations for Practitioners: Quantitative methods instructors should emphasize practice in their quantitative courses and consider providing additional support for students through the inclusion of lab sections, tutoring, and/or differentiation. Pre-testing statistical ability at the start of a course is also suggested to better meet student needs. Impact on Society: The ultimate goal of quantitative methods in doctoral education is to produce high-quality educational researchers who are prepared to apply their knowledge to problems and research in education. Results of the present study can inform faculty and administrator decisions in doctoral education to best support this goal. Future Research: Using the student perspectives presented in the present study, future researchers should continue to explore effective instructional strategies and curriculum design within education doctoral programs. The inclusion of student voice can strengthen
Stress in doctors and dentists who teach.
Rutter, Harry; Herzberg, Joe; Paice, Elisabeth
2002-06-01
To explore the relationship between a teaching role and stress in doctors and dentists who teach. Medline, PubMed, BIDS database for social sciences literature, and the ERIC database for educational literature were searched using the key words 'stress' or 'burnout' with the terms doctor, physician, dentist, teacher, lecturer, academic staff, and university staff. Other books and journals known to the authors were also used. Many studies have shown high levels of stress in doctors, dentists, teachers, and lecturers. A large number of factors are implicated, including low autonomy, work overload, and lack of congruence between power and responsibility. Doctors and dentists who take on a teaching role in addition to their clinical role may increase their levels of stress, but there is also evidence that this dual role may reduce job-related stress. Working as a doctor or dentist may entail higher levels of stress than are experienced by the general population. In some situations adding in the role of teacher reduces this stress, but more research is needed to explain this finding.

A smart-card-enabled privacy preserving E-prescription system.
Yang, Yanjiang; Han, Xiaoxi; Bao, Feng; Deng, Robert H
2004-03-01
Within the overall context of protection of health care information, privacy of prescription data needs special treatment. First, the involvement of diverse parties, especially nonmedical parties in the process of drug prescription complicates the protection of prescription data. Second, both patients and doctors have privacy stakes in prescription, and their privacy should be equally protected. Third, the following facts determine that prescription should not be processed in a truly anonymous manner: certain involved parties conduct useful research on the basis of aggregation of prescription data that are linkable with respect to either the patients or the doctors; prescription data has to be identifiable in some extreme circumstances, e.g., under the court order for inspection and assign liability. In this paper, we propose an e-prescription system to address issues pertaining to the privacy protection in the process of drug prescription. In our system, patients' smart cards play an important role. For one thing, the smart cards are implemented to be portable repositories carrying up-to-date personal medical records and insurance information, providing doctors instant data access crucial to the process of diagnosis and prescription. For the other, with the secret signing key being stored inside, the smart card enables the patient to sign electronically the prescription pad, declaring his acceptance of the prescription. To make the system more realistic, we identify the needs for a patient to delegate his signing capability to other people so as to protect the privacy of information housed on his card. A strong proxy signature scheme achieving technologically mutual agreements on the delegation is proposed to implement the delegation functionality.

Small signal absorption measurements of the incident coherent radiation by the metal surface have revealed an increase in the absorption by the surface in presence of transparent/semi-transparent particulates on it. This effect, identified as field enhanced surface absorption, has been found to increase with reduction in the average particulate size. Consequently higher laser assisted removal efficiency of contamination from a metal surface has been observed for smaller contaminant particulates. These measurements have been carried out utilizing coherent radiations of two different wavelengths so chosen that for one the particulates are totally transparent while for the other they are partially transparent.

Knowledge and attitudes of doctors toward the sexuality of older people in Turkey.
Dogan, Sultan; Demir, Basaran; Eker, Engin; Karim, Salman
2008-10-01
Few studies have looked at healthcare professionals' knowledge of and attitudes to later life sexuality in both Western and Eastern cultures. Here we examine the attitudes and knowledge of Turkish medical doctors toward sexuality in older people. Eighty-seven doctors, from various specialties, who were directly involved in the care of older people, were contacted by post and asked to complete the Turkish version of the Aging Sexual Knowledge and Attitudes Scale (ASKAS). A majority of physicians indicated that they had limited information and knowledge regarding sexual health issues in older people (69%). Although a small percentage (14.5%) reported that they "always" discuss sexuality and sexual problems with older patients, the majority (69%) indicated that they "sometimes" raise questions about sexuality with these patients. A high percentage (81%) stated that they would be helpful and receptive should an elderly patient initiate a discussion about sexual issues. Most participants (77%) thought that the patient's gender was of no importance when taking a sexual history. Overall, the responses to ASKAS showed that physicians had limited knowledge but their attitude was positive toward sexuality in the elderly. Female physicians had less knowledge than males and had more negative attitudes toward sexuality in this age group. Total and knowledge subscale scores of ASKAS showed that older physicians had more knowledge than younger physicians but similar attitudes. A comparison of the knowledge and attitude scores of psychiatrists, surgeons and non-surgeons showed no significant difference among the three groups. This study identified a low level of awareness of later life sexuality among Turkish medical doctors. These findings identify a need to improve the education and training of doctors at both undergraduate and postgraduate levels to enable them to provide better sexual health care to older people.

Attracting and retaining doctors in rural Nepal.
Shankar, P R
2010-01-01
In Nepal, a number of private sector medical schools have opened recently; although sufficient numbers of doctors are graduating there continues to be a doctor shortage in rural areas. This article analysed the rural doctor shortage in Nepal and reviewed the international literature for strategies that may be suitable for use in Nepal. Original research articles, reviews, magazine articles and project reports dealing with Nepal and other developing countries during the period 1995 to 2010 were sourced via Google, Google Scholar and Pubmed. Full text access was obtained via WHO's HINARI database. The health workforce in Nepal is unevenly distributed resulting in doctor shortages in rural areas. The recent introduction of mandatory rural service for scholarship students was aimed to reduce the loss of medical graduates to developed nations. High tuition fees in private medical schools and low Government wages prevent recent graduates from taking up rural positions, and those who do face many challenges. Potential corrective strategies include community-based medical education, selecting rural-background medical students, and providing a partial or complete tuition fee waiver for medical students who commit to rural service. Traditional healers and paramedical staff can also be trained for and authorized to provide rural health care. A range of strategies developed elsewhere could be used in Nepal, especially community-oriented medical education that involves rural doctors in training medical students. The reimbursement of tuition fees, assistance with relocation, and provision of opportunities for academic and professional advancement for rural doctors should also be considered. Government investment in improving working conditions in rural Nepal would assist rural communities to attract and retain doctors.

Marine research is a dynamic thematic focus in Kiel, Germany, uniting natural scientists, economists, lawyers, philosophers, artists and computing and medical scientists in frontier research on the scientific, economic and legal aspects of the seas. The contributing institutions are Kiel University, GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel Institute for the World Economy and Muthesius University in Kiel. Marine science education in Kiel trains young scientists to investigate the role of the oceans in global change, risks arising from ocean usage and sustainable management of living and non-living marine resources. Basic fundamental research is supplemented with applied science in an international framework including partners from industry and public life. The Integrated School of Ocean Sciences (ISOS) established through the Cluster of Excellence "The Future Ocean", funded within the German Excellence Initiative, provides PhD candidates in marine sciences with interdisciplinary education outside of curricular courses. It supports the doctoral candidates through supplementary training, a framework of supervision, mentoring and mobility, the advisors through transparency and support of doctoral training in their research proposals and the contributing institutions by ensuring quality, innovation and excellence in marine doctoral education. All PhD candidates financed by the Helmholtz Research School for Ocean System Science and Technology (HOSST) and the Collaborative Research Centre 754 "Climate-biogeochemical interactions in the tropical ocean" (SFB 754) are enrolled at the ISOS and are integrated into the larger peer community. Over 150 PhD candidate members from 6 faculties form a large interdisciplinary network. At the ISOS, they sharpen their scientific profile, are challenged to think beyond their discipline and equip themselves for life after a PhD through early exposure to topics beyond research (e.g. social responsibility, public communication

Enabling opportunistic resources for CMS Computing Operations
Energy Technology Data Exchange (ETDEWEB)
Hufnagel, Dick [Fermilab
2015-11-19
With the increased pressure on computing brought by the higher energy and luminosity from the LHC in Run 2, CMS Computing Operations expects to require the ability to utilize “opportunistic” resources — resources not owned by, or a priori configured for CMS — to meet peak demands. In addition to our dedicated resources we look to add computing resources from non CMS grids, cloud resources, and national supercomputing centers. CMS uses the HTCondor/glideinWMS job submission infrastructure for all its batch processing, so such resources will need to be transparently integrated into its glideinWMS pool. Bosco and parrot wrappers are used to enable access and bring the CMS environment into these non CMS resources. Here we describe our strategy to supplement our native capabilities with opportunistic resources and our experience so far using them.

2014-07-01
Full Text Available The aim of the paper is to evaluate the accountability and transparency of Italian non profits organizations. The main goal is to understand if a general accountability or transparency problem, or a systematic publicity deficit, exist in the third sector in Italy. Non profit organizations have an ethical obligation to their stakeholder and to the public to conduct their activities with accountability and transparency. Non profit organizations should regularly and openly convey information to the stakeholder about their vision, mission, objectives, activities, accomplishments, decision-making processes and organizational structure. Information from a non profit organization should be easily accessible to the stakeholder and should create external visibility, public understanding and trust in the organization, conditions necessary to find donors. Non profit organizations work with communities and community donors need to know how their money is used. In the first part the analysis of the definition of transparency and accountability is made and the sustainability report like an important instrument of communication is considered. In the second part an empirical research is presented. The Italian law allows taxpayers to devote 5 per thousand of their income tax to non profit organizations, choosing between charities, social promotion associations, recognized associations, entities dedicated to scientific research and health care, universities, municipal social services and other non profit organizations. The present study present a quantitative research and it’s based on an empirical analysis of non-profit organizations that receive this donation in Italy in the year 2010 and 2011. In the paper we analyze the transparency and the accountability of the top 100 non profit organizations that have received the contribution of 5 per thousand, checking whether they prepare their Sustainability Report or any other kind of report for communicate the use

Transparent and Flexible Supercapacitors with Networked Electrodes.
Kiruthika, S; Sow, Chaitali; Kulkarni, G U
2017-10-01
Transparent and flexible energy storage devices have received immense attention due to their suitability for innovative electronics and displays. However, it remains a great challenge to fabricate devices with high storage capacity and high degree of transmittance. This study describes a simple process for fabrication of supercapacitors with ≈75% of visible transparency and areal capacitance of ≈3 mF cm -2 with high stability tested over 5000 cycles of charging and discharging. The electrodes consist of Au wire networks obtained by a simple crackle template method which are coated with MnO 2 nanostructures by electrodeposition process. Importantly, the membrane separator itself is employed as substrate to bring in the desired transparency and light weight while additionally exploiting its porous nature in enhancing the interaction of electrolyte with the active material from both sides of the substrate, thereby enhancing the storage capacity. The method opens up new ways for fabricating transparent devices. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Improving the quality and transparency of governmental healthcare decision-making has an impact on the health of the population through policies, organisational management and clinical practice. Moreover, the comparison between healthcare centres and the transparent feedback of results to professionals and to the wider public contribute directly to improved results. The "Results Centre" of the Catalan healthcare system measures and disseminates the results achieved by the different healthcare centres in order to facilitate a shared decision-making process, thereby enhancing the quality of healthcare provided to the population of Catalonia (Spain). This is a pioneering initiative in Spain and is aligned with the most advanced countries in terms of policies of transparency and accountability. Copyright © 2016 SESPAS.

Semantic transparency affects morphological priming . . . eventually.
Heyer, Vera; Kornishova, Dana
2018-05-01
Semantic transparency has been in the focus of psycholinguistic research for decades, with the controversy about the time course of the application of morpho-semantic information during the processing of morphologically complex words not yet resolved. This study reports two masked priming studies with English - ness and Russian - ost' nominalisations, investigating how semantic transparency modulates native speakers' morphological priming effects at short and long stimulus onset asynchronies (SOAs). In both languages, we found increased morphological priming for nominalisations at the transparent end of the scale (e.g. paleness - pale) in comparison to items at the opaque end of the scale (e.g. business - busy) but only at longer prime durations. The present findings are in line with models that posit an initial phase of morpho-orthographic (semantically blind) decomposition.

Full Text Available Not only in Europe but also on other continents, it is felt that a reform of the doctoral phase in tertiary education is necessary. To make this reform a success, it is necessary to first define the skills and competences of a doctor in general and of a doctor of engineering in particular to dispose of measurable criteria for the outcomes of the reform. These criteria are intended to foster not only an academic career but also careers in industry and administration, i.e. to support the careers of future chief executives. It is also presented how these skills and competences are seen by industrial companies as well as by the young Doctors of Engineering. Finally, it is discussed how existing methods might be reformed to further improve the doctoral phase at and in cooperation with universities.

A quantum mechanical approach is used to study high momentum transfer reactions in which a nucleon is knocked out of the nucleus. We show that the nuclear interactions of the wave packet produced in such a process tend to cancel, so that the nuclear medium becomes transparent. The wave packet (ejectile)-nucleon interactions, including the production of nucleon resonances are also discussed. Color transparency effects in the (e,e'p) reaction may be significant at relatively low momentum transfer Q 2 = 3 - 6 (GeV 2 /c) 2 . 17 refs., 3 figs

EDITORIAL: On display with transparent conducting films On display with transparent conducting films
Demming, Anna
2012-03-01
Transparent conducting films were already featuring in scientific literature over one hundred years ago. In 1894 Aryton and Mather described a conducting varnish for coating the screens of electric apparatus so they would not charge when accidentally brushed by a coat sleeve or other material [1]. Their method began with a similar approach to that used to make savoury jellies; by dissolving gelatine in vinegar, after which less palatable ingredients were incorporated including sulphuric acid and an antisulphuric enamel. While the search for transparent conducting films continued to attract other researchers, the same problem remained: the transparency would be compromised if the film was too thick, and the conductivity would be compromised if the film was too thin. In the early 1950s Gillham and Preston reported that thin gold films sputtered on bismuth oxide and heated resulted in a material that successfully combined the previously mutually exclusive properties of transparency and conductivity [2]. Other oxide films were also found to favourably combine these properties, including tin oxide, as reported by Ishiguro and colleagues in Japan in 1958 [3]. Today tin oxide doped with indium (ITO) has become the industry standard for transparent conducting films in a range of applications including photovoltaic technology and displays. It is perhaps the mounting ubiquity of electronic displays as a result of the increasingly digitised and computerised environment of the modern day world that has begun to underline the main drawback of ITO: expense. In this issue, a collaboration of researchers in Korea present an overview of graphene as a transparent conducting material with the potential to replace ITO in a range of electronic and optoelectronic applications [4]. One of the first innovations in optical microscopy was the use of dyes. This principle first came into practice with the use of ultraviolet light to reveal previously indistinguishable features.

Full Text Available Background: The number of doctoral programmes in nursing has multiplied rapidly throughout the world. This has led to widespread concern about nursing doctoral education, specifically with regard to the quality of curricula and faculty, as well as to the availability of appropriate institutional resources. In South Africa, no study of these issues has been conducted at a national level. Objective: To explore and describe the quality of nursing doctoral education in South Africa from the perspectives of deans, faculty, doctoral graduates and students. Method: A cross-sectional survey design was used. All deans (N = 15; n = 12, faculty (N = 50; n = 26, doctoral graduates (N = 43; n = 26 and students (N = 106; n = 63 at South African nursing schools that offer a nursing doctoral programme (N = 16; n = 15 were invited to participate. Data were collected by means of structured email-mediated Quality of Nursing Doctoral Education surveys. Results: Overall, the graduate participants scored their programme quality most positively of all the groups and faculty scored it most negatively. All of the groups rated the quality of their doctoral programmes as good, but certain problems related to the quality of resources, students and faculty were identified. Conclusion: These evaluations, by the people directly involved in the programmes, demonstrated significant differences amongst the groups and thus provide valuable baseline data for building strategies to improve the quality of doctoral nursing education in South Africa.

Part-time working is a growing phenomenon in medicine, which is expected to influence informal networks at work differently compared to full-time working. The opportunity to meet and build up social capital at work has offered a basis for theoretical arguments. Twenty-eight teams of medical specialists in the Netherlands, including 226 individuals participated in this study. Interviews with team representatives and individual questionnaires were used. Data were gathered on three types of networks: relationships of consulting, communication and trust. For analyses, network and multilevel applications were used. Differences between individual doctors and between teams were both analysed, taking the dependency structure of the data into account, because networks of individual doctors are not independent. Teams were divided into teams with and without doctors working part-time. Contrary to expectations we found no impact of part-time working on the size of personal networks, neither at the individual nor at the team level. The same was found regarding efficient reachability. Whereas we expected part-time doctors to choose their relations as efficiently as possible, we even found the opposite in intended relationships of trust, implying that efficiency in reaching each other was higher for full-time doctors. But we found as expected that in mixed teams with part-time doctors the frequency of regular communication was less compared to full-time teams. Furthermore, as expected the strength of the intended relationships of trust of part-time and full-time doctors was equally high. From these findings we can conclude that part-time doctors are not aiming at efficiency by limiting the size of networks or by efficient reachability, because they want to contact their colleagues directly in order to prevent from communication errors. On the other hand, together with the growth of teams, we found this strategy, focussed on reaching all colleagues, was diminishing. And our data

Full Text Available The aim of the study was to investigate the impact of different levels of packaging transparency on the evaluation of attractiveness of a product within the packaging, in relation to whether it is a healthy or unhealthy product. Consumer preferences during buying decision process were also investigated. The study was conducted by two methods. The first one was related to consumer preferences and was based on a choice task, while the other one was related to packaging attractiveness and was based on subjective evaluation expressed through the Likert scale. Eight samples of packaging were used. They differed according to product type (healthy and unhealthy, and the level of transparency (fully transparent packaging, packaging with two windows, packaging with one window and non-transparent packaging. According to the results, consumers tend to ignore non-transparent packaging, regardless the product healthiness. The findings indicate the importance of thoughtful selection of packaging structure and its material in design process and launching the food products on the retail market.

Full Text Available The preparation and publication of dissertations can be viewed as a subsystem of scholarly communication, and the treatment of data that support doctoral research can be mapped in a very controlled manner to the data curation lifecycle. Dissertation datasets represent “low-hanging fruit” for universities who are developing institutional data collections. The current workflow for processing electronic theses and dissertations (ETD at a typical American university is presented, and a new practice is proposed that includes datasets in the process of formulating, awarding, and disseminating dissertations in a way that enables them to be linked and curated together. The value proposition and new roles for the university and its student-authors, faculty, graduate programs and librarians are explored.

Transparent conducting oxides and production thereof are disclosed. An exemplary method of producing a transparent conducting oxide (TCO) material may comprise: providing a TCO target doped with either a high-permittivity oxide or a low-permittivity oxide in a process chamber. The method may also comprise depositing a metal oxide on the target in the process chamber to form a thin film having enhanced optical properties without substantially decreasing electrical quality.

The light-mater interaction in quantum dots doped artificial electromagnetic materials such as metamaterial waveguides has been studied. The effect of surface plasmon polaritons (SPPs) on the absorption coefficient of quantum dots in metamaterial waveguides is investigated. The waveguides are made by sandwiching a metamaterial slab between two dielectric material layers. An ensemble of quantum dots are deposited near the waveguide interfaces. The transfer matrix method is used to calculate the SSPs in the waveguide and the density matrix method and Schrödinger equation method are used to calculate the absorption spectrum. It is found that when the thickness of the metamaterial slab is greater than the SPP wavelength the SPP energy is degenerate. However when the thickness of the slab is smaller than that of the SPP wavelength the degeneracy of SPP state splits into odd and even SPP modes due the surface mode interaction (SMI) of the waveguide. We also found that the absorption spectrum has a minima (transparent state) which is due to strong coupling between excitons in quantum dots and SPPs in the waveguide. This transparent state is called the SPP induced transparency. However when the thickness of the slab is smaller than that of the SPP wavelength one transparent state in the absorption spectrum split into two transparent states due to the surface mode interaction. This type of transparency is called the SMI induced transparency. Transparent states can be achieved by applying pulse stress field or an intense laser pulse field. Hence present findings can be used to fabricate the metamaterial optical sensors and switches. (paper)
Transparency: the emerging third dimension of Open Science and Open Data

Liz Lyon
2016-03-01
Full Text Available This paper presents an exploration of the concept of research transparency. The policy context is described and situated within the broader arena of open science. This is followed by commentary on transparency within the research process, which includes a brief overview of the related concept of reproducibility and the associated elements of research integrity, fraud and retractions. A two-dimensional model or continuum of open science is considered and the paper builds on this foundation by presenting a three-dimensional model, which includes the additional axis of ‘transparency’. The concept is further unpacked and preliminary definitions of key terms are introduced: transparency, transparency action, transparency agent and transparency tool. An important linkage is made to the research lifecycle as a setting for potential transparency interventions by libraries. Four areas are highlighted as foci for enhanced engagement with transparency goals: Leadership and Policy, Advocacy and Training, Research Infrastructures and Workforce Development.
Tunable phonon-induced transparency in bilayer graphene nanoribbons.
Yan, Hugen; Low, Tony; Guinea, Francisco; Xia, Fengnian; Avouris, Phaedon

In the phenomenon of plasmon-induced transparency, which is a classical analogue of electromagnetically induced transparency (EIT) in atomic gases, the coherent interference between two plasmon modes results in an optical transparency window in a broad absorption spectrum. With the requirement of contrasting lifetimes, typically one of the plasmon modes involved is a dark mode that has limited coupling to the electromagnetic radiation and possesses relatively longer lifetime. Plasmon-induced transparency not only leads to light transmission at otherwise opaque frequency regions but also results in the slowing of light group velocity and enhanced optical nonlinearity. In this article, we report an analogous behavior, denoted as phonon-induced transparency (PIT), in AB-stacked bilayer graphene nanoribbons. Here, light absorption due to the plasmon excitation is suppressed in a narrow window due to the coupling with the infrared active Γ-point optical phonon, whose function here is similar to that of the dark plasmon mode in the plasmon-induced transparency. We further show that PIT in bilayer graphene is actively tunable by electrostatic gating and estimate a maximum slow light factor of around 500 at the phonon frequency of 1580 cm(-1), based on the measured spectra. Our demonstration opens an avenue for the exploration of few-photon nonlinear optics and slow light in this novel two-dimensional material.

The fundamental challenge in designing transparent pressure sensors is the ideal combination of high optical transparency and high pressure sensitivity. Satisfying these competing demands is commonly achieved by a compromise between the transparency and usage of a patterned dielectric surface, which increases pressure sensitivity, but decreases transparency. Herein, a design strategy for fabricating high-transparency and high-sensitivity capacitive pressure sensors is proposed, which relies on the multiple states of nanoparticle dispersity resulting in enhanced surface roughness and light transmittance. We utilize two nanoparticle dispersion states on a surface: (i) homogeneous dispersion, where each nanoparticle (≈500 nm) with a size comparable to the visible light wavelength has low light scattering; and (ii) heterogeneous dispersion, where aggregated nanoparticles form a micrometer-sized feature, increasing pressure sensitivity. This approach is experimentally verified using a nanoparticle-dispersed polymer composite, which has high pressure sensitivity (1.0 kPa -1 ), and demonstrates excellent transparency (>95%). We demonstrate that the integration of nanoparticle-dispersed capacitor elements into an array readily yields a real-time pressure monitoring application and a fully functional touch device capable of acting as a pressure sensor-based input device, thereby opening up new avenues to establish processing techniques that are effective on the nanoscale yet applicable to macroscopic processing. © 2018 WILEY-VCH Verlag GmbH & Co.

Double optomechanical transparency with direct mechanical interaction

2015-01-01
We present a mechanism for double transparency in an optomechanical system. This mechanism is based on the coupling of a moving cavity mirror to a second mechanical oscillator. Due to the purely mechanical coupling and the radiation pressure, three pathways are established for excitations of the probe photons into the cavity photons. Destructive interference occurs at two different frequencies, leading to double transparency to the probe field. It is the coupling strength between the mechanical oscillators that determines the locations of the transparency windows. Moreover, the normal splitting appears for the generated Stokes field and the four-wave mixing process is inhibited on resonance. (paper)

Clinical leadership is considered essential for maintaining and improving patient care and safety in the UK, and is incorporated in the curriculum for all trainee doctors. Despite the growing focus on the importance of leadership, and the introduction of the Medical Leadership Competency Framework (MLCF) in the UK, leadership education for doctors in training is still in its infancy. Assessment is focused on clinical skills, and trainee doctors receive very little formal feedback on their leadership competencies. In this article we describe the approach taken by Health Education Kent, Sussex and Surrey (HEKSS) to raise the profile of leadership amongst doctors in training in the South Thames Foundation School (STFS). An annual structured formative assessment in leadership for each trainee has been introduced, supported by leadership education for both trainees and their supervisors in HEKSS trusts. We analysed over 500 of these assessments from the academic year 2012/13 for foundation doctors in HEKSS trusts, in order to assess the quality of the feedback. From the analysis, potential indicators of more effective formative assessments were identified. These may be helpful in improving the leadership education programme for future years. There is a wealth of evidence to highlight the importance and value of formative assessments; however, particularly for foundation doctors, these have typically been focused on assessing clinical capabilities. This HEKSS initiative encourages doctors to recognise leadership opportunities at the beginning of their careers, seeks to help them understand the importance of acquiring leadership skills and provides structured feedback to help them improve. Leadership education for doctors in training is still in its infancy. © 2015 John Wiley & Sons Ltd.

Based on the linear coordinate transformation method, two-dimensional and three-dimensional electromagnetic transparent devices with diamond shape composed of homogeneous and non-singular materials are proposed in this paper. The permittivity and permeability tensors of the transparent devices are derived. The performance and scattering properties of the transparent devices are confirmed by a full-wave simulation. It can physically protect electric devices such as an antenna and a radar station inside, without sacrificing their performance. This work represents important progress towards the practical realization of metamaterial-assisted transparent devices and expands the application of transformation optics.

Basic self-knowledge and transparency.
Borgoni, Cristina
2018-01-01
Cogito -like judgments, a term coined by Burge (1988), comprise thoughts such as, I am now thinking , I [hereby] judge that Los Angeles is at the same latitude as North Africa, or I [hereby] intend to go to the opera tonight. It is widely accepted that we form cogito -like judgments in an authoritative and not merely empirical manner. We have privileged self-knowledge of the mental state that is self-ascribed in a cogito -like judgment. Thus, models of self-knowledge that aim to explain privileged self-knowledge should have the resources to explain the special self-knowledge involved in cogito judgments. My objective in this paper is to examine whether a transparency model of self-knowledge (i.e., models based on Evans ' 1982 remarks) can provide such an explanation: granted that cogito judgments are paradigmatic cases of privileged self-knowledge, does the transparency procedure explain why this is so? The paper advances a negative answer, arguing that the transparency procedure cannot generate the type of thought constitutive of cogito judgments.

Transparent lattice characterization with gated turn-by-turn data of diagnostic bunch train
Li, Yongjun; Cheng, Weixing; Ha, Kiman; Rainer, Robert
2017-11-01
Methods of characterization of a storage ring's lattice have traditionally been intrusive to routine operations. More importantly, the lattice seen by particles can drift with the beam current due to collective effects. To circumvent this, we have developed a novel approach for dynamically characterizing a storage ring's lattice that is transparent to operations. Our approach adopts a dedicated filling pattern which has a short, separate diagnostic bunch train (DBT). Through the use of a bunch-by-bunch feedback system, the DBT can be selectively excited on demand. Gated functionality of a beam position monitor system is capable of collecting turn-by-turn data of the DBT, from which the lattice can then be characterized after excitation. As the DBT comprises only about one percent of the total operational bunches, the effects of its excitation are negligible to users. This approach allows us to localize the distributed quadrupolar wakefields generated in the storage ring vacuum chamber during beam accumulation. While effectively transparent to operations, our approach enables us to dynamically control the beta beat and phase beat, and unobtrusively optimize performance of the National Synchrotron Light Source-II accelerator during routine operations.
