The main predictors of functional impairment in the elderly are alterations in mental or communication functions. To study mental and communication functions in rural elderly subjects of Mapuche and non Mapuche origin. Elderly subjects coming from a rural Mapuche community and a non Mapuche community were studied. Subjects were interviewed at their homes. The communication and mental function assessments of the Functional Autonomy Measurement System were applied. Fifty one Mapuche and 49 non Mapuche subjects with a mean age of 71 +/- 7 and 74 +/- 8 years respectively, were studied. Fifty four percent were female and 31% were illiterate. Twenty six percent had impairment in mental functions. The item with the highest difficulty was memory. The visual function was the most severely impaired among communication items. Mapuche elderly subjects had significantly higher degrees of impairment in mental and communication functions. There is a higher degree of mental and communication impairment among rural Mapuche elderly subjects than in their non Mapuche counterparts.

Depressive and anxiety disorders cause great suffering and disability and are associated with high health care costs. In a previous conducted pragmatic randomised controlled trial, we have shown that a concise format of cognitive behavioural- and/or pharmacotherapy is as effective as standard care in reducing depressive and anxiety symptoms and in improving subdomains of general health and quality of life in secondary care psychiatric outpatients. In this economic evaluation, we examined whether a favourable cost-utility of concise care compared to standard care was attained. The economic evaluation was performed alongside a pragmatic randomised controlled trial. Health-related quality of life was measured using the Short-Form (SF-36) questionnaire. Cost of healthcare utilization and productivity loss (absenteeism and presenteeism) were assessed using the Trimbos/iMTA questionnaire for Costs associated with Psychiatric Illness (TiC-P). A cost-utility analysis, using cost-effectiveness acceptability curves, comparing differences in societal costs and Quality-Adjusted Life Years (QALYs) at 1 year was performed. One year after study entry, the difference in mean cost per patient of the two primary treatments was not significant between both groups. No significant differences in other healthcare and non- healthcare costs could be detected between patients receiving concise care and standard care. Also, QALYs were not statistically different between the groups during the study period. From both the societal and healthcare perspective, the probability that concise care is more cost-effective compared to standard care remains below the turning point of 0.5 for all acceptable values of the willingness to pay for a QALY. The economic evaluation suggests that concise care is unlikely to be cost-effective compared to standard care in the treatment for depressive- and anxiety disorders in secondary mental health care during a one year follow up period.

Concise nuclear isobar charts

Energy Technology Data Exchange (ETDEWEB)

Bucka, H.

1986-01-01

In the Concise Nuclear Isobar Charts, data on binding energies of protons and neutrons in the ground state and excitation energies for low-lying nuclear energy levels are displayed, both of which are of great interest for transition processes as well as for questions of nuclear structure. Also, quantum numbers for angular momentum and parity are shown for these energy levels. For the stable nuclei, data for the relative abundances, and for unstable nucleon configurations, the transition probabilities are included in the data displayed. Due to the representation chosen for the atomic nuclei, in many cases a very clear first survey of systematic properties of nuclear energy states as well as spontaneous decay processes is achieved.

2018-01-01

A major predicament for Intensive Care Unit (ICU) patients is inconsistent and ineffective communication means. Patients rated most communication sessions as difficult and unsuccessful. This, in turn, can cause distress, unrecognized pain, anxiety, and fear. As such, we designed a portable BCI system for ICU communications (BCI4ICU) optimized to operate effectively in an ICU environment. The system utilizes a wearable EEG cap coupled with an Android app designed on a mobile device that serves as visual stimuli and data processing module. Furthermore, to overcome the challenges that BCI systems face today in real-world scenarios, we propose a novel subject-specific Gaussian Mixture Model- (GMM-) based training and adaptation algorithm. First, we incorporate subject-specific information in the training phase of the SSVEP identification model using GMM-based training and adaptation. We evaluate subject-specific models against other subjects. Subsequently, from the GMM discriminative scores, we generate the transformed vectors, which are passed to our predictive model. Finally, the adapted mixture mean scores of the subject-specific GMMs are utilized to generate the high-dimensional supervectors. Our experimental results demonstrate that the proposed system achieved 98.7% average identification accuracy, which is promising in order to provide effective and consistent communication for patients in the intensive care.

Plain language techniques are health literacy universal precautions intended to enhance health care system navigation and health outcomes. Physical activity (PA) is a popular topic on the Internet, yet it is unknown if information is communicated in plain language. This study examined how plain language techniques are included in PA websites, and if the use of plain language techniques varies according to search procedures (keyword, search engine) and website host source (government, commercial, educational/organizational). Three keywords ("physical activity," "fitness," and "exercise") were independently entered into three search engines (Google, Bing, and Yahoo) to locate a nonprobability sample of websites ( N = 61). Fourteen plain language techniques were coded within each website to examine content formatting, clarity and conciseness, and multimedia use. Approximately half ( M = 6.59; SD = 1.68) of the plain language techniques were included in each website. Keyword physical activity resulted in websites with fewer clear and concise plain language techniques ( p websites with more clear and concise techniques ( p language techniques did not vary by search engine or the website host source. Accessing PA information that is easy to understand and behaviorally oriented may remain a challenge for users. Transdisciplinary collaborations are needed to optimize plain language techniques while communicating online PA information.

2015-01-01

Although many pediatric intensive care units (PICUs) use beside communication sheets (BCSs) to highlight daily goals, the optimal format is unknown. A site-specific BCS could improve both PICU communication and compliance completing the BCS. Via written survey, PICU staff at an academic children's hospital provided recommendations for improving and revising an existing BCS. Pre- and post-BCS revision, PICU staff were polled regarding PICU communication and BCS effectiveness, and daily compliance for completing the BCS was monitored. After implementation of the revised BCS, staff reporting "excellent" or "very good" day-to-day communication within the PICU increased from 57% to 77% (P = .02). Compliance for completing the BCS also increased significantly (75% vs 83%, P = .03). Introduction of a focused and concise BCS tailored to a specific PICU leads to improved perceptions of communication by PICU staff and increased compliance completing the daily BCS. © The Author(s) 2014.

The development of communicating modular cardiac rhythm management systems relies on effective intrabody communication between a subcutaneous implantable cardioverter-defibrillator (S-ICD) and a leadless pacemaker (LP), using conducted communication. Communication success is affected by the LP and S-ICD orientation. This study is designed to evaluate the orientation of the LP and S-ICD in canine subjects and measure success and threshold of intrabody communication. To gain more human insights, we will explore device orientation in LP and S-ICD patients. Canine subjects implanted with a prototype S-ICD and LP (both Boston Scientific, MA, USA) with anterior-posterior fluoroscopy images were included in this analysis. For comparison, a retrospective analysis of human S-ICD and LP patients was performed. The angle of the long axis of the LP towards the vertical axis of 0°, and distance between the coil and LP were measured. Twenty-three canine subjects were analysed. Median angle of the LP was 29° and median distance of the S-ICD coil to LP was 0.8 cm. All canine subjects had successful communication. The median communicating threshold was 2.5 V. In the human retrospective analysis, 72 LP patients and 100 S-ICD patients were included. The mean angle of the LP was 56° and the median distance between the S-ICD coil and LP was 4.6 cm. Despite the less favourable LP orientation in canine subjects, all communication attempts were successful. In the human subjects, we observed a greater and in theory more favourable LP angle towards the communication vector. These data suggests suitability of human anatomy for conductive intrabody communication.

This study investigates the effects of cultural norms on family health history (FHH) communication in the American, Chinese, and Korean cultures. More particularly, this study focuses on perceived family boundaries, subjective norms, stigma beliefs, and privacy boundaries, including age and gender, that affect people's FHH communication. For data analyses, hierarchical multiple regression and logistic regression methods were employed. The results indicate that participants' subjective norms, stigma beliefs, and perceived family/privacy boundaries were positively associated with current FHH communication. Age- and gender-related privacy boundaries were negatively related to perceived privacy boundaries, however. Finally, the results show that gendered cultural identities have three-way interaction effects on two associations: (1) between perceived family boundaries and perceived privacy boundaries and (2) between perceived privacy boundaries and current FHH communication. The findings have meaningful implications for future cross-cultural studies on the roles of family systems, subjective norms, and stigma beliefs in FHH communication.

The influence of marine biofilms on corrosion: A concise review

Little, Brenda J.; Lee, Jason S.; Ray, Richard I.

2008-01-01

The following is a concise review of the literature that addresses the impact of marine biofilms on two phenomena-ennoblement of corrosion potential and sulfide derivitization due to sulfate-reducing bacteria. A universally defined mechanism of potential ennoblement has not been established. Extent of ennoblement varies among locations and the extent of ennoblement for a particular material cannot be used to predict an increased likelihood of localized corrosion. There is some controversy as to the susceptibility of low- and medium-grade stainless steels. Carbon steel and copper alloys are susceptible to sulfide derivitization but thermodynamic models cannot predict the susceptibility of these materials. Laboratory experiments designed to provide data on susceptibility to sulfide derivitization have produced conflicting results because of the following: (1) laboratory media can contain anions that inhibit localized corrosion, (2) laboratory media can contain yeast extract that interferes with electrochemical measurements, and (3) deaeration procedures can produce environments that are not conducive for the growth of sulfate-reducing bacteria. In general, alloys that undergo ennoblement are not vulnerable to sulfide derivitization and conversely, alloys that are subject to sulfide derivitization do not become ennobled

2015-01-01

This book provides an introduction to the basic ideas and tools used in mathematical analysis. It is a hybrid cross between an advanced calculus and a more advanced analysis text and covers topics in both real and complex variables. Considerable space is given to developing Riemann integration theory in higher dimensions, including a rigorous treatment of Fubini's theorem, polar coordinates and the divergence theorem. These are used in the final chapter to derive Cauchy's formula, which is then applied to prove some of the basic properties of analytic functions. Among the unusual features of this book is the treatment of analytic function theory as an application of ideas and results in real analysis. For instance, Cauchy's integral formula for analytic functions is derived as an application of the divergence theorem. The last section of each chapter is devoted to exercises that should be viewed as an integral part of the text. A Concise Introduction to Analysis should appeal to upper level undergraduate math...

In this paper we present a concise expression of the classical electromagnetic radiation spectrum of a moving charge. It is shown to be equivalent to the often used and much more complicated form derived from the Lienard-Wiechert potentials when the observation distance R satisfies the condition R much-gt γλ. The expression reveals a relationship between the radiation spectrum and the motion of the radiation source. It also forms the basis of an efficient computing approach, which is of practical value in numerical calculations of the spectral output of accelerated charges. The advantages of this approach for analytical and numerical applications are discussed and the bending-magnet synchrotron radiation spectrum is calculated according to the approach

Neuroplasticity associated with tactile language communication in a deaf-blind subject

Directory of Open Access Journals (Sweden)

Souzana Obretenova

2010-01-01

Full Text Available A longstanding debate in cognitive neuroscience pertains to the innate nature of language development and the underlying factors that determine this faculty. We explored the neural correlates associated with language processing in a unique individual who is early blind, congenitally deaf, and possesses a high level of language function. Using functional magnetic resonance imaging (fMRI, we compared the neural networks associated with the tactile reading of words presented in Braille, Print on Palm (POP, and a haptic form of American Sign Language (haptic ASL or hASL. With all three modes of tactile communication, indentifying words was associated with robust activation within occipital cortical regions as well as posterior superior temporal and inferior frontal language areas (lateralized within the left hemisphere. In a normally sighted and hearing interpreter, identifying words through hASL was associated with left-lateralized activation of inferior frontal language areas however robust occipital cortex activation was not observed. Diffusion tensor imaging (DTI-based tractography revealed differences consistent with enhanced occipital-temporal connectivity in the deaf-blind subject. Our results demonstrate that in the case of early onset of both visual and auditory deprivation, tactile-based communication is associated with an extensive cortical network implicating occipital as well as posterior superior temporal and frontal associated language areas. The cortical areas activated in this deaf-blind subject are consistent with characteristic cortical regions previously implicated with language. Finally, the resilience of language function within the context of early and combined visual and auditory deprivation may be related to enhanced connectivity between relevant cortical areas.

A Concise and Direct Proof of "Fermat's Last Theorem"

Ellman, Roger

1998-01-01

The recently developed proof of Fermat's Last Theorem is very lengthy and difficult, so much so as to be beyond all but a small body of specialists. While certainly of value in the developments that resulted, that proof could not be, nor was offered as being, possibly the proof Fermat had in mind. The present proof being brief, direct and concise is a candidate for being what Fermat had in mind. It is also completely accessible to any one trained in common algebra.

Background Neurocognitive (NC) impairment (NCI) occurs commonly in people living with HIV. Despite substantial effort, no biomarkers have been sufficiently validated for diagnosis and prognosis of NCI in the clinic. The goal of this project was to identify diagnostic or prognostic biomarkers for NCI in a comprehensively characterized HIV cohort. Methods Multidisciplinary case review selected 98 HIV-infected individuals and categorized them into four NC groups using normative data: stably normal (SN), stably impaired (SI), worsening (Wo), or improving (Im). All subjects underwent comprehensive NC testing, phlebotomy, and lumbar puncture at two timepoints separated by a median of 6.2 months. Eight biomarkers were measured in CSF and blood by immunoassay. Results were analyzed using mixed model linear regression and staged recursive partitioning. Results At the first visit, subjects were mostly middle-aged (median 45) white (58%) men (84%) who had AIDS (70%). Of the 73% who took antiretroviral therapy (ART), 54% had HIV RNA levels below 50 c/mL in plasma. Mixed model linear regression identified that only MCP-1 in CSF was associated with neurocognitive change group. Recursive partitioning models aimed at diagnosis (i.e., correctly classifying neurocognitive status at the first visit) were complex and required most biomarkers to achieve misclassification limits. In contrast, prognostic models were more efficient. A combination of three biomarkers (sCD14, MCP-1, SDF-1α) correctly classified 82% of Wo and SN subjects, including 88% of SN subjects. A combination of two biomarkers (MCP-1, TNF-α) correctly classified 81% of Im and SI subjects, including 100% of SI subjects. Conclusions This analysis of well-characterized individuals identified concise panels of biomarkers associated with NC change. Across all analyses, the two most frequently identified biomarkers were sCD14 and MCP-1, indicators of monocyte/macrophage activation. While the panels differed depending on

The geometry of special relativity a concise course

CERN Document Server

Dragon, Norbert

2012-01-01

In this concise primer it is shown that, with simple diagrams, the phenomena of time dilatation, length contraction and Lorentz transformations can be deduced from the fact that in a vacuum one cannot distinguish physically straight and uniform motion from rest, and that the speed of light does not depend on the speed of either the source or the observer. The text proceeds to derive the important results of relativistic physics and to resolve its apparent paradoxes. A short introduction into the covariant formulation of electrodynamics is also given. This publication addresses, in particular, students of physics and mathematics in their final undergraduate year.

Does bone measurement on the radius indicate skeletal status. Concise communication

International Nuclear Information System (INIS)

Mazess, R.B.; Peppler, W.W.; Chesney, R.W.; Lange, T.A.; Lindgren, U.; Smith, E. Jr.

1984-01-01

Single-photon (I-125) absorptiometry was used to measure bone mineral content (BMC) of the distal third of the radius, and dual-photon absorptiometry (Gd-153) was used to measure total-body bone mineral (TBBM), as well as the BMC of major skeletal regions. Measurements were done in normal females, normal males, osteoporotic females, osteoporotic males, and renal patients. The BMC of the radius predicted TBBM well in normal subjects, but was less satisfactory in the patient groups. The spinal BMC was predicted with even lower accuracy from radius measurement. The error in predicting areal density (bone mass per unit projected skeletal area) of the lumbar and thoracic spine from the radius BMC divided by its width was smaller, but the regressions differed significantly among normals, osteoporotics, and renal patients. There was a preferential spinal osteopenia in the osteoporotic group and in about half of the renal patients. Bone measurements on the radius can indicate overall skeletal status in normal subjects and to a lesser degree in patients, but these radius measurements are inaccurate, even on the average, as an indicator of spinal state

You talkin' to me? Interactive playback is a powerful yet underused tool in animal communication research.

Science.gov (United States)

King, Stephanie L

2015-07-01

Over the years, playback experiments have helped further our understanding of the wonderful world of animal communication. They have provided fundamental insights into animal behaviour and the function of communicative signals in numerous taxa. As important as these experiments are, however, there is strong evidence to suggest that the information conveyed in a signal may only have value when presented interactively. By their very nature, signalling exchanges are interactive and therefore, an interactive playback design is a powerful tool for examining the function of such exchanges. While researchers working on frog and songbird vocal interactions have long championed interactive playback, it remains surprisingly underused across other taxa. The interactive playback approach is not limited to studies of acoustic signalling, but can be applied to other sensory modalities, including visual, chemical and electrical communication. Here, I discuss interactive playback as a potent yet underused technique in the field of animal behaviour. I present a concise review of studies that have used interactive playback thus far, describe how it can be applied, and discuss its limitations and challenges. My hope is that this review will result in more scientists applying this innovative technique to their own study subjects, as a means of furthering our understanding of the function of signalling interactions in animal communication systems. © 2015 The Author(s) Published by the Royal Society.

Younger generations are extensive users of digital devices; these technologies have always existed and have always been a part of their lives. Video games are a big part of their digital experience. User-centered design is an approach to designing systems informed by scientific knowledge of how people think, act, and coordinate to accomplish their goals. There is an emerging field of intervention research looking into using these techniques to produce video games that can be applied to healthcare. Games with the purpose of improving an individual's knowledge, skills, or attitudes in the "real" world are called "Serious Games". Before doctors and patients can consider using Serious Games as a useful solution for a health care-related problem, it is important that they first are aware of them, have a basic understanding of what they are, and what, if any, claims on their effectiveness exist. In order to bridge that gap, we have produced this concise overview to introduce physicians to the subject at hand.

Interior structure of rotating black holes. I. Concise derivation

International Nuclear Information System (INIS)

Hamilton, Andrew J. S.; Polhemus, Gavin

2011-01-01

This paper presents a concise derivation of a new set of solutions for the interior structure of accreting, rotating black holes. The solutions are conformally stationary, axisymmetric, and conformally separable. Hyper-relativistic counter-streaming between freely-falling collisionless ingoing and outgoing streams leads to mass inflation at the inner horizon, followed by collapse. The solutions fail at an exponentially tiny radius, where the rotational motion of the streams becomes comparable to their radial motion. The papers provide a fully nonlinear, dynamical solution for the interior structure of a rotating black hole from just above the inner horizon inward, down to a tiny scale.

Effect of bolus composition on esophageal transit: concise communication

1982-01-01

The technique of esophageal scintigraphy was developed as a sensitive, quantitative, noninvasive test of esophageal transit. Esophageal scintigraphy was performed in 40 asymptomatic normal volunteers in order to determine the effect on esophageal transit of the following: body posture (sitting vs. supine), liquid vs. solid, the solid being either a standard gelatin capsule of the size used for antibiotic capsules, or a cube of solid food such as cooked chicken liver. The results showed that liquids emptied completely from the esophagus after one swallow whether supine or sitting. Capsules or liver cubes, when ingested without water, frequently remained in the esophagus for up to two hours without the subject's having any sensation that the solid had not left the esophagus. Both capsules and liver cubes cleared the esophagus better in the upright than in the supine position. When gelatin capsules were swallowed with as little as 15 ml of water, but after a preliminary sip of water, there was complete transit in each case. The study suggests that the practice of assisting patients into a sitting position and instructing them to take a sip of water before attempting to swallow a capsule will assure better transit of the capsule even when swallowed with as little as 15 ml of water. This may reduce the incidence of esophagitis following oral antibiotics, and of esophageal erosions from aspirin-containing medications

Generating Concise Rules for Human Motion Retrieval

Science.gov (United States)

Mukai, Tomohiko; Wakisaka, Ken-Ichi; Kuriyama, Shigeru

This paper proposes a method for retrieving human motion data with concise retrieval rules based on the spatio-temporal features of motion appearance. Our method first converts motion clip into a form of clausal language that represents geometrical relations between body parts and their temporal relationship. A retrieval rule is then learned from the set of manually classified examples using inductive logic programming (ILP). ILP automatically discovers the essential rule in the same clausal form with a user-defined hypothesis-testing procedure. All motions are indexed using this clausal language, and the desired clips are retrieved by subsequence matching using the rule. Such rule-based retrieval offers reasonable performance and the rule can be intuitively edited in the same language form. Consequently, our method enables efficient and flexible search from a large dataset with simple query language.

1978-01-01

Radionuclide bone imaging was performed in a rabbit model to observe the course of fracture healing and to establish criteria for distinguishing nonunion and delayed healing from normal healing. Sequential gamma-camera images (with pinhole collimator) were collected and subjected to computer analysis. Five groups were established: (a) control--immobilization; (b) control--immobilization plus periosteal stripping; (c) simple fracture--osteotomy; (d) delayed union--osteotomy plus periosteal stripping; and (e) nonunion--osteotomy, periosteal stripping and polymethyl methacrylate interposed between fracture fragments. Histographic representation of absolute count rates along rabbit tibias followed a predictable pattern in the simple-fracture and delayed-union groups. They differed only in the time of appearance of phases. The non-union group demonstrated no recognizable sequential pattern. In this experimental model, serial bone scanning the quantitative data analysis has shown potential for indicating the course of healing in fractures and for serving as a guide to treatment

Communication skills play a key role in many aspects of both medical education and clinical patient care. The objectives of this study were to identify the key components of communication skills from the perspectives of both orthopaedic residents and their program directors and to understand how these skills are currently taught. This study utilized a mixed methods design. Quantitative data were collected with use of a thirty-item questionnaire distributed to all Canadian orthopaedic residents. Qualitative data were collected through focus groups with orthopaedic residents and semistructured interviews with orthopaedic program directors. One hundred and nineteen (37%) of 325 questionnaires were completed, twelve residents participated in two focus groups, and nine of sixteen program directors from across the country were interviewed. Both program directors and residents identified communication skills as being the accurate and appropriate use of language (i.e., content skills), not how the communication was presented (i.e., process skills). Perceived barriers to effective communication included time constraints and the need to adapt to the many personalities and types of people encountered daily in the hospital. Residents rarely have explicit training in communication skills. They rely on communication training implicitly taught through observation of their preceptors and clinical experience interacting with patients, peers, and other health-care professionals. Orthopaedic residents and program directors focus on content and flexibility within communication skills as well as on the importance of being concise. They value the development of communication skills in the clinical environment through experiential learning and role modeling. Education should focus on developing residents' process skills in communication. Care should be taken to avoid large-group didactic teaching sessions, which are perceived as ineffective.

For severely paralyzed people, a brain-computer interface (BCI) provides a way of re-establishing communication. Although subjects with muscular dystrophy (MD) appear to be potential BCI users, the actual long-term effects of BCI use on brain activities in MD subjects have yet to be clarified. To investigate these effects, we followed BCI use by a chronic tetraplegic subject with MD over 5 months. The topographic changes in an electroencephalogram (EEG) after long-term use of the virtual reality (VR)-based BCI were also assessed. Our originally developed BCI system was used to classify an EEG recorded over the sensorimotor cortex in real time and estimate the user's motor intention (MI) in 3 different limb movements: feet, left hand, and right hand. An avatar in the internet-based VR was controlled in accordance with the results of the EEG classification by the BCI. The subject was trained to control his avatar via the BCI by strolling in the VR for 1 hour a day and then continued the same training twice a month at his home. After the training, the error rate of the EEG classification decreased from 40% to 28%. The subject successfully walked around in the VR using only his MI and chatted with other users through a voice-chat function embedded in the internet-based VR. With this improvement in BCI control, event-related desynchronization (ERD) following MI was significantly enhanced (p < 0.01) for feet MI (from -29% to -55%), left-hand MI (from -23% to -42%), and right-hand MI (from -22% to -51%). These results show that our subject with severe MD was able to learn to control his EEG signal and communicate with other users through use of VR navigation and suggest that an internet-based VR has the potential to provide paralyzed people with the opportunity for easy communication.

The scattering of an electromagnetic wave by a set of dielectric and metallic spheres is a well-known physical problem. We show a mathematical simplification of the multiple-scattering theory. In this paper, we will establish the multiple-scattering equation in two different ways. Through the study of the equation form, we can choose the simplest spherical wave expansion for calculations. Then, we propose concise expressions of the Mie scattering coefficients and translation coefficients for both polarizations. With these simplified expressions, large spheres are studied without loss of accuracy. Far-field expressions, cross-sections, and the scattering matrix are also simplified. Thus, we obtain formulas that can be easily understood from a physical point of view.

Full Text Available The Concise Data Processing Assessment (CDPA was developed to probe student abilities related to the nature of measurement and uncertainty and to handling data. The diagnostic is a ten question, multiple-choice test that can be used as both a pre-test and post-test. A key component of the development process was interviews with students, which were used to both uncover common modes of student thinking and validate item wording. To evaluate the reliability and discriminatory power of this diagnostic, we performed statistical tests focusing on both item analysis (item difficulty index, item discrimination index, and point-biserial coefficient and on the entire test (test reliability and Ferguson’s delta. Scores on the CDPA range from chance (for novices to about 80% (for experts, indicating that it possesses good dynamic range. Overall, the results indicate that the CDPA is a reliable assessment tool for measuring targeted abilities in undergraduate physics students.

A Concise and Comprehensive Description of Shoulder Pathology and Procedures: The 4D Code System

Directory of Open Access Journals (Sweden)

Laurent Lafosse

2012-01-01

Full Text Available Background. We introduce a novel description system of shoulder pathoanatomy. Its goal is to provide a comprehensive three-dimensional picture, with an additional component of time; thus, we call it the 4D code. Methods. Each line of the code starts with right versus left and a time designation. The pillar components are recorded regardless of pathology; they include subscapularis, long head of biceps tendon, supraspinatus, infraspinatus, and teres minor. Secondary elements can be added if there is observed pathology, including acromioclavicular joint, glenohumeral joint, labrum, tear configuration, location and extent of partial cuff tear, calcific tendonitis, fatty infiltration, and neuropathy. Results. We provide two illustrative examples of patients which show the ease and effectiveness of the 4D code. With a few simple lines, significant amount of information about patients’ pathology, surgery, and recovery can be easily conveyed. Discussion. We utilize existing validated classification systems for parts of the shoulder and provide a frame work to build a comprehensive picture. The alphanumeric code provides a simple language that is universally understood. The 4D code is concise yet complete. It seeks to improve efficiency and accuracy of the communication, documentation, and visualization of shoulder pathology within individual practices and between providers.

Scientific communication across the Iron Curtain

Hollings, Christopher D

2016-01-01

This monograph provides a concise introduction to the tangled issues of communication between Russian and Western scientists during the Cold War. It details the extent to which mid-twentieth-century researchers and practitioners were able to communicate with their counterparts on the opposite side of the Iron Curtain. Drawing upon evidence from a range of disciplines, a decade-by-decade account is first given of the varying levels of contact that existed via private correspondence and conference attendance. Next, the book examines the exchange of publications and the availability of one side's work in the libraries of the other. It then goes on to compare general language abilities on opposite sides of the Iron Curtain, with comments on efforts in the West to learn Russian and the systematic translation of Russian work. In the end, author Christopher Hollings argues that physical accessibility was generally good in both directions, but that Western scientists were afflicted by greater linguistic difficultie...

A concise resistor model for wall temperature prediction in diesel engines with piston cooling is presented here. The model uses the instantaneous in-cylinder pressure and some usually measured operational parameters to predict the temperature of the structural elements of the engine. The resistor model was adjusted by means of temperature measurements in the cylinder head, the liner and the piston. For each model parameter, an expression as a function of the engine geometry, operational parameters and material properties was derived to make the model applicable to other similar engines. The model predicts well the cylinder head, liner and piston temperature and is sensitive to variations of operational parameters such as the start of injection, coolant and oil temperature and engine speed and load.

Epidemiological and health promotion studies in obese subjects are hampered by the difficulty of obtaining a representative sample from the community. The enrollment process can be at high risk of stigmatization. The purpose of this study is to describe an original information and communication technologies (ICT) strategy to get around these ethical and methodological difficulties. A multimedia campaign of communication was organized on the topic of overweight and quality of life (QoL). A specific website was developed to collect via a questionnaire QoL data as well as information related to patient's needs and health perception from participants. To promote the website, multiple information supports were largely diffused. Primary care professionals were solicited to enhance the enrollment. The campaign started with a press conference covered by the main television channels. The ICT-based approach allowed the participation of 4,155 subjects homogeneously distributed with respect to body mass index, age, gender and socioeconomic level. A high percentage of subjects fully completed the web-based questionnaire. The press conference allowed reaching a quarter of the total sample within 5 days. Overweight remains a major public health problem. This survey showed that a holistic approach supported by ICT is a promising way to recruit obese subjects without stigmatizing the disorder.

2010-01-01

Physician–patient email communication is gaining popularity. However, a formal assessment of physicians' email communication skills has not been described. We hypothesized that the email communication skills of rheumatology fellows can be measured in an objective structured clinical examination (OSCE) setting using a novel email content analysis instrument which has 18 items. During an OSCE, we asked 50 rheumatology fellows to respond to a simulated patient email. The content of the responses was assessed using our instrument. The majority of rheumatology fellows wrote appropriate responses scoring a mean (±SD) of 10.6 (±2.6) points (maximum score 18), with high inter-rater reliability (0.86). Most fellows were concise (74%) and courteous (68%) but not formal (22%). Ninety-two percent of fellows acknowledged that the patient's condition required urgent medical attention, but only 30% took active measures to contact the patient. No one encrypted their messages. The objective assessment of email communication skills is possible using simulated emails in an OSCE setting. The variable email communication scores and incidental patient safety gaps identified, suggest a need for further training and defined proficiency standards for physicians' email communication skills.

A concise course on stochastic partial differential equations

CERN Document Server

Prévôt, Claudia

2007-01-01

These lectures concentrate on (nonlinear) stochastic partial differential equations (SPDE) of evolutionary type. All kinds of dynamics with stochastic influence in nature or man-made complex systems can be modelled by such equations. To keep the technicalities minimal we confine ourselves to the case where the noise term is given by a stochastic integral w.r.t. a cylindrical Wiener process.But all results can be easily generalized to SPDE with more general noises such as, for instance, stochastic integral w.r.t. a continuous local martingale. There are basically three approaches to analyze SPDE: the "martingale measure approach", the "mild solution approach" and the "variational approach". The purpose of these notes is to give a concise and as self-contained as possible an introduction to the "variational approach". A large part of necessary background material, such as definitions and results from the theory of Hilbert spaces, are included in appendices.

Highlights: • An off-design performance simulation of triple-pressure reheat HRSG is executed. • The bottoming cycle characteristics of energy transfer/conversion are analyzed. • Concise formulas for the off-design performance of bottoming cycle are proposed. • The accuracy of the formulas is verified under different load control strategies. • The errors of the formulas are generally within 1% at a load of 100–50%. - Abstract: Concise semi-theoretical, semi-empirical formulas are developed in this study to predict the off-design performance of the bottoming cycle of the gas–steam turbine combined cycle. The formulas merely refer to the key thermodynamic design parameters (full load parameters) of the bottoming cycle and off-design gas turbine exhaust temperature and flow, which are convenient in determining the overall performance of the bottoming cycle. First, a triple-pressure reheat heat recovery steam generator (HRSG) is modeled, and thermodynamic analysis is performed. Second, concise semi-theoretical, semi-empirical performance prediction formulas for the bottoming cycle are proposed through a comprehensive analysis of the heat transfer characteristics of the HRSG and the energy conversion characteristics of the steam turbine under the off-design condition. The concise formulas are found to be effective, i.e., fast, simple, and precise in obtaining the thermodynamic parameters for bottoming cycle efficiency, HRSG heat transfer capacity, HRSG efficiency, steam turbine power output, and steam turbine efficiency under the off-design condition. Accuracy is verified by comparing the concise formulas’ calculation results with the simulation results and practical operation data under different load control strategies. The calculation errors are within 1.5% (mainly less than 1% for both simulation and actual operation data) under combined cycle load (gas turbine load) ranging from 50% to 100%. However, accuracy declines sharply when the turbine

Communicating stereotype-relevant information: is factual information subject to the same communication biases as fictional information?

Goodman, Ruth L; Webb, Thomas L; Stewart, Andrew J

2009-07-01

Factual information is more frequently read and discussed than fictional information. However, research on the role of communication in shaping stereotypes has focused almost exclusively on fictional narratives. In Experiments 1 and 2 a newspaper article containing information about heroin users was communicated along chains of 4 people. No stereotype-consistency bias was observed. Instead, a greater proportion of stereotype-inconsistent information was communicated than was stereotype-consistent or -neutral information. Three further experiments investigated explanations for the difference between the communication of fictional and factual information. Experiment 3 ruled out the possibility that participants' beliefs about the validity of the information could influence the way that it is communicated. Experiments 4 and 5 divided information into concrete (a specific event or fact) or abstract (opinion). A stereotype-consistency bias emerged only for abstract information. In summary, linguistic abstraction moderates whether stereotype-consistency biases emerge in the communication of stereotype-relevant factual information.

Full Text Available The article reveals the phenomenological aspects of the communication process. The importance of the more detailed analysis of developments in the subjective foundation of information space. A new approach to communication is associated with a new look at the world, it puts new emphasis on the methodology of knowledge. According to the author the specifics of postmodern social situation due to the fact that society has become transparent (clear through a radical change in the technology of mass communication. Existing induces derealization communicative reality, when the signal transmission rate in the range of our planet can be equated to instant, and the distance and time of the message are extremely small, approaching zero. Therefore, the conclusion is that there is another, more sophisticated communicative community that is virtual, which establishes a fundamentally different circuit, or a model of the communicative process.  Investigated that in contrast to the current actually expresses integrity, stability and completeness, virtual reality is the source of the difference and diversity. Thus virtuality is a phenomenon, immanent in the very structure of existence, embodies the creative opportunity-generating activities. The article reveals that virtual reality is based on the principle of «feedback» that allows for the maximum entry of a person into the information space.The scale of the phenomenon of virtual manifestations in social and individual life suggests the «virtualization» of society and encourages researchers to develop a new understanding of social reality in its relation to the reality of the virtual. At the same time virtual model is the result of the synthesis of human sensory and mental abilities, but taken in their generality, the idea of the correlation between man and objects in the world. Hense, his model has a priori importance, because it incorporated all rational isolated situations where it may be. Innovation

Institute of Scientific and Technical Information of China (English)

无

2009-01-01

Communication based train control (CBTC) system is based on mobile communication and overcomes fixed blocks in order to increase track utilization and train safety. The data communication system (DCS) between trains and wayside equipment is a crucial factor for the safe and efficient operation of CBTC system. The dependability under various transmission conditions needs to be modeled and evaluated. In this paper,a stochastic reward net (SRN) model for DCS based IEEE 802.11 standard was developed,which captures all relevant failure and failure recovery behavior system aspects in a concise way. We compared the reliability,availability for DCS with and without access point (AP) and antenna redundant configuration. We also quantitatively evaluated and compared the frame loss probability for three DCS configurations with different train velocities and train numbers in one radio cell. Fixed-point iteration was adopted to simplify the analysis. Numerical results showed the significant improvement of the reliability,availability and the frame loss probability index for the full redundant configuration.

Essential Biodiversity Variables: A framework for communication between the biodiversity community and space agencies

Science.gov (United States)

Leidner, A. K.; Skidmore, A. K.; Turner, W. W.; Geller, G. N.

2017-12-01

The biodiversity community is working towards developing a consensus on a set of Essential Biodiversity Variables (EBVs) that can be used to measure and monitor biodiversity change over time. These EBVs will inform research, modeling, policy, and assessment efforts. The synoptic coverage provided by satellite data make remote sensing a particularly important observation tool to inform many EBVs. Biodiversity is a relatively new subject matter for space agencies, and thus the definition, description, and requirements of EBVs with a significant remote sensing component can foster ways for the biodiversity community to clearly and concisely communicate observational needs to space agencies and the Committee on Earth Observing Satellites (CEOS, the international coordinating body for civilian space agencies). Here, we present an overview of EBVs with a particular emphasis on those for which remote sensing will play a significant role and also report on the results of recent workshops to prioritize and refine EBVs. Our goal is to provide a framework for the biodiversity community to coalesce around a set of observational needs to convey to space agencies. Compared to many physical science disciplines, the biodiversity community represents a wide range of sub-disciplines and organizations (academia, non-governmental organizations, research institutes, national and local natural resource management agencies, etc.), which creates additional challenges when communicating needs to space agencies unfamiliar with the topic. EBVs thus offer a communication pathway that could increase awareness within space agencies of the uses of remote sensing for biodiversity research and applications, which in turn could foster greater use of remote sensing in the broader biodiversity community.

Ronaghi, Mohammad; Nasr, Marjan; Heller, Stefan

2012-01-01

Hearing loss, caused by irreversible loss of cochlear sensory hair cells, affects millions of patients worldwide. In this concise review, we examine the conundrum of inner ear stem cells, which obviously are present in the inner ear sensory epithelia of nonmammalian vertebrates, giving these ears the ability to functionally recover even from repetitive ototoxic insults. Despite the inability of the mammalian inner ear to regenerate lost hair cells, there is evidence for cells with regenerative capacity because stem cells can be isolated from vestibular sensory epithelia and from the neonatal cochlea. Challenges and recent progress toward identification of the intrinsic and extrinsic signaling pathways that could be used to re-establish stemness in the mammalian organ of Corti are discussed.

Lesthaeghe, Ron

2014-12-23

This article gives a concise overview of the theoretical development of the concept of the "second demographic transition" since it was coined in 1986, its components, and its applicability, first to European populations and subsequently also to non-European societies as well. Both the demographic and the societal contrasts between the first demographic transition (FDT) and the second demographic transition (SDT) are highlighted. Then, the major criticisms of the SDT theory are outlined, and these issues are discussed in the light of the most recent developments in Europe, the United States, the Far East, and Latin America. It turns out that three major SDT patterns have developed and that these evolutions are contingent on much older systems of kinship and family organization.

Sick leave due to mental disorders is a societal problem. It carries a high cost in terms of loss of labor productivity and absenteeism. Partial remission increases the risk of relapse after a return to work. There is sometimes a difference between the ability to return to work as judged by a general practitioner (GP) and the needs of the workplace. GPs are the main controllers of treatment and tend to protect their patients. Communication and agreement by GPs and occupational physicians play an effective role in the return to work. However, it requires considerable effort for both of them to make time to do this. We have developed a concise set of files for a smooth return to work. The files consist of three parts: "Suggestions for corresponding with employees taking sick leave"; "Checklist for smooth return to work"; and "Pattern of living". We put them into practice among 20 companies in Japan from January 2012 to October 2013. The companies had 8244 workers in total and 116 workers were on sick-leave due to mental disorders. Our set of files contributed to sharing the written basic policy of return to work among employees on sick leave with mental disorders, GPs, occupational physicians and personnel officers. That sharing led to facilitating a smooth return to work. Although there are differences in the legal and medical systems between Japan and other countries, our concept of sharing the written basic policy may give some help to occupational physicians in other parts of the world as well.

A Concise Review of Amyloidosis in Animals

Directory of Open Access Journals (Sweden)

Moges Woldemeskel

2012-01-01

Full Text Available Amyloidosis refers to a group of protein misfolding diseases characterized by deposition of a particular amyloid protein in various organs and tissues of animals and humans. Various types and clinical forms of amyloidosis, in which the pathology and pathogenesis is diverse depending upon the underlying causes and species affected, are reported in domestic and wild animals. The clinical findings are also quite variable consequent to the variation of the tissues and organs involved and the extent of functional disruption of the affected organs in various animal species. The affected organs may be enlarged and exhibit variable pallor grossly, or the amyloid deposit may be discernible only after microscopic examination of the affected tissues. Amyloid appears as a pale eosinophilic homogenous extracellular deposit in tissues. However, microscopic examination and Congo red staining with green birefringence under polarized light are needed to confirm amyloid and differentiate it from other apparently similar extracellular deposits such as collagen and fibrin. Identifying the type of amyloid deposit needs immunohistochemical staining, ultrastructural characterization of the amyloid fibril, and if feasible also genetic studies of the involved species for clinical and prognostic purposes. This paper provides a concise review of the occurrence of amyloidosis in domestic and wild animals.

A compressed-air nebulizer with low holdup and high output was used to nebulize [/sup 99m/Tc] pertechnetate presented in normal saline. Generated droplets were dried in line and led to an inhalation chamber from which the dry aerosol was inhaled using a nose or mouth inhalation unit. The mass median diameter of the particles was 0.8 microns, with an associated geometric standard deviation of 2.0. The deep lung delivery efficiency--defined as the ratio of the activity deposited in the lung area to the activity nebulized--was found to be reproducible and consistent (15 to 22%) in all the subjects studied. A 3 to 5 min inhalation of aerosol, nebulized from 20 mCi, was sufficient to provide a lung image of good information density. No noticeable deposit was seen in the trachea or major bronchi. The system is inexpensive, stable in performance, adaptable to other solutions or colloids, and is promising for routine use

Quantum spin systems on infinite lattices a concise introduction

CERN Document Server

Naaijkens, Pieter

2017-01-01

This course-based primer offers readers a concise introduction to the description of quantum mechanical systems with infinitely many degrees of freedom – and quantum spin systems in particular – using the operator algebraic approach. Here, the observables are modeled using elements of some operator algebra, usually a C*-algebra. This text introduces readers to the framework and the necessary mathematical tools without assuming much mathematical background, making it more accessible than advanced monographs. The book also highlights the usefulness of the so-called thermodynamic limit of quantum spin systems, which is the limit of infinite system size. For example, this makes it possible to clearly distinguish between local and global properties, without having to keep track of the system size. Together with Lieb-Robinson bounds, which play a similar role in quantum spin systems to that of the speed of light in relativistic theories, this approach allows ideas from relativistic field theories to be implemen...

In order to investigate the swelling behavior and fuel–cladding interaction mechanism of U–10Zr alloy metallic fuel at very low burnup, an irradiation experiment was concisely designed and conducted on the China Mianyang Research Reactor. Two types of irradiation samples were designed for studying free swelling without restraint and the fuel–cladding interaction mechanism. A new bonding material, namely, pure aluminum powder, was used to fill the gap between the fuel slug and sample shell for reducing thermal resistance and allowing the expansion of the fuel slug. In this paper, the concise irradiation rig design is introduced, and the neutronic and thermal–hydraulic analyses, which were carried out mainly using MCNP (Monte Carlo N-Particle) and FLUENT codes, are presented. Out-of-pile tests were conducted prior to irradiation to verify the manufacturing quality and hydraulic performance of the rig. Nondestructive postirradiation examinations using cold neutron radiography technology were conducted to check fuel cladding integrity and swelling behavior. The results of the preliminary examinations confirmed the safety and effectiveness of the design

Decentralized Model Predictive Control for Cooperative Multiple Vehicles Subject to Communication Loss

Directory of Open Access Journals (Sweden)

Hojjat A. Izadi

2011-01-01

Full Text Available The decentralized model predictive control (DMPC of multiple cooperative vehicles with the possibility of communication loss/delay is investigated. The neighboring vehicles exchange their predicted trajectories at every sample time to maintain the cooperation objectives. In the event of a communication loss (packet dropout, the most recent available information, which is potentially delayed, is used. Then the communication loss problem changes to a cooperative problem when random large communication delays are present. Such large communication delays can lead to poor cooperation performance and unsafe behaviors such as collisions. A new DMPC approach is developed to improve the cooperation performance and achieve safety in the presence of the large communication delays. The proposed DMPC architecture estimates the tail of neighbor's trajectory which is not available due to the large communication delays for improving the performance. The concept of the tube MPC is also employed to provide the safety of the fleet against collisions, in the presence of large intervehicle communication delays. In this approach, a tube shaped trajectory set is assumed around the trajectory of the neighboring vehicles whose trajectory is delayed/lost. The radius of tube is a function of the communication delay and vehicle's maneuverability (in the absence of model uncertainty. The simulation of formation problem of multiple vehicles is employed to illustrate the effectiveness of the proposed approach.

So from the perspective of the subject, it is observed that the new technological devices and their new grammars are utilized provided they contribute with meaning to his daily practice and biographical trajectory. Nevertheless, digital inclusion policies have focused only on maximizing access to equipment and digital literacy associated to technology applications and not to the narrative skills of the subjects. It is therefore necessary to generate new concepts that allow new methodological guidelines, in communication and education academic processes, to promote the use of new emerging digital spaces for communicational empowered citizens, that is, from competent to tell (expressive skills to more specifically, tell oneself (as an individual and tell us (collectively. Finally, these will be the expressive spaces of the new television with citizen´s expressions, fostered by converging elements of digital technology.

Science communication in the field of fundamental biomedical research (editorial).

2017-10-01

The aim of this special issue on science communication is to inspire and help scientists who are taking part or want to take part in science communication and engage with the wider public, clinicians, other scientists or policy makers. For this, some articles provide concise and accessible advice to individual scientists, science networks, or learned societies on how to communicate effectively; others share rationales, objectives and aims, experiences, implementation strategies and resources derived from existing long-term science communication initiatives. Although this issue is primarily addressing scientists working in the field of biomedical research, much of it similarly applies to scientists from other disciplines. Furthermore, we hope that this issue will also be used as a helpful resource by academic science communicators and social scientists, as a collection that highlights some of the major communication challenges that the biomedical sciences face, and which provides interesting case studies of initiatives that use a breadth of strategies to address these challenges. In this editorial, we first discuss why we should communicate our science and contemplate some of the different approaches, aspirations and definitions of science communication. We then address the specific challenges that researchers in the biomedical sciences are faced with when engaging with wider audiences. Finally, we explain the rationales and contents of the different articles in this issue and the various science communication initiatives and strategies discussed in each of them, whilst also providing some information on the wide range of further science communication activities in the biomedical sciences that could not all be covered here.

Traditionally, CM is relegated to a support role in project management activities. CM s traditional functions of identification, change control, status accounting, and audits/verification are still necessary and play a vital role. However, this presentation proposes CM s role in a new and innovative manner that will significantly improve communication throughout the organization and, in turn, augment the project s success. CM s new role is elevated to the project management level, above the engineering or sub-project level in the Work Breakdown Structure (WBS), where it can more effectively accommodate changes, reduce corrective actions, and ensure that requirements are clear, concise, and valid, and that results conform to the requirements. By elevating CM s role in project management and orchestrating new measures, a new communication will emerge that will improve information integrity, structured baselines, interchangeability/traceability, metrics, conformance to standards, and standardize the best practices in the organization. Overall project performance (schedule, quality, and cost) can be no better than the ability to communicate requirements which, in turn, is no better than the CM process to communicate project decisions and the correct requirements.

Purpose Assertive communication has been associated with higher levels of condom use among youth using self-report survey methodology. The purpose of this study was to examine the subjective ratings of assertiveness among young, romantically-involved couples in the context of a condom negotiation task. Methods Using an innovative video-recall procedure, 32 couples (64 youth) engaged in a videotaped condom negotiation task and then rated self and partners’ level of assertiveness. Both individual ratings of assertiveness and couple-level assertiveness were assessed using dyadic hierarchical linear modeling. Results Individuals’ assertiveness was positively associated with condom use. Unexpectedly, the overall level of assertiveness in couples showed a curvilinear association with condom use. Very high and very low assertiveness was associated with lower condom use, while moderate levels of assertiveness were associated with higher condom use. Conclusions Moderate levels of assertiveness during condom negotiation may facilitate condom use in young couples. Increasing condom use among romantic partners may require developing interventions that strengthen youths’ ability to engage in assertive communication strategies that balance emotional intimacy with self-advocacy.

Concise method for evaluating the probability distribution of the marginal cost of power generation

International Nuclear Information System (INIS)

Zhang, S.H.; Li, Y.Z.

2000-01-01

In the developing electricity market, many questions on electricity pricing and the risk modelling of forward contracts require the evaluation of the expected value and probability distribution of the short-run marginal cost of power generation at any given time. A concise forecasting method is provided, which is consistent with the definitions of marginal costs and the techniques of probabilistic production costing. The method embodies clear physical concepts, so that it can be easily understood theoretically and computationally realised. A numerical example has been used to test the proposed method. (author)

Patterns of interhemispheric correlation during human communication.

Grinberg-Zylberbaum, J; Ramos, J

1987-09-01

Correlation patterns between the electroencephalographic activity of both hemispheres in adult subjects were obtained. The morphology of these patterns for one subject was compared with another subject's patterns during control situations without communication, and during sessions in which direct communication was stimulated. Neither verbalization nor visual or physical contact are necessary for direct communication to occur. The interhemispheric correlation patterns for each subject were observed to become similar during the communication sessions as compared to the control situations. These effects are not due to nonspecific factors such as habituation or fatigue. The results support the syntergic theory proposed by one of the authors (Grinberg-Zylberbaum).

Poor and inadequate communication affects the therapeutic relationship between doctors and patients. Guided by this idea, we organized a minor elective course entitled "communication skills". We wanted to bring closer to the students the holistic approach of the family physician to the patient, the importance of the family, its impact on the patient and vice versa, and the significance of the local community and its influence on an individual's health. The aim of this article is to explain how we organized this elective course. The course was organized in the form of 12 hours of theory (3 lectures and 9 seminars) and 24 hours of practical training. There were 26 students from all years. Through theory, and even more through the practical part the students met with different types of patients. At the end of the course, students in lower years were evaluated by means of an interview, and graduate students through a practical test - a conversation with a patient. The initial results, including the students' grading of this course, were highly encouraging. Both teachers and students were highly satisfied on completion of the course. Content on communication training is rare in teaching. Practicing communication skills will empower the doctor - patient therapeutic relationship.

To analyze the communication resources reported by managers in the business environment and compare the resources used to those reported by business professionals. 82 professionals volunteered to participate in the research, divided into 50 managers (MP) and 32 business professionals (BP) from industry section in Caxias do Sul and the surrounding region (Brazil). A questionnaire with 4 topics was used: personal data, self-assessment of communicative behavior, self-assessment of communicative resources, and selection of positive and negative resources influencing communication. Regarding communicative behavior, both groups reported normal voice but with significant differences regarding the use of softness in communication, 25% of MP and only 4% of BP. Both groups selected the following main positive resources: knowledge of subject, use of proper vocabulary, and objectivity. The negative resources were, similarly, the lack of subject domain, criticism or prejudgment, and improper vocabulary. Finally, analyzing the degree of influence of each communicative resource, the MP highlighted tone of voice as an important positive resource, while the BP pointed the subject domain. Still, the monotonous voice for MP and nervousness for BP were indicated as the main negative influences. Managers value more communicative resources connected to communicative attitude, such as tone of voice and expression, while business professionals worry about demonstrating security and technical understanding of the subject.

Effects of noise and task loading on a communication task loading on a communication task

Science.gov (United States)

Orrell, Dean H., II

Previous research had shown the effect of noise on a single communication task. This research has been criticized as not being representative of a real world situation since subjects allocated all of their attention to only one task. In the present study, the effect of adding a loading task to a standard noise-communication paradigm was investigated. Subjects performed both a communication task (Modified Rhyme Test; House et al. 1965) and a short term memory task (Sternberg, 1969) in simulated levels of aircraft noise (95, 105 and 115 dB overall sound pressure level (OASPL)). Task loading was varied with Sternberg's task by requiring subjects to memorize one, four, or six alphanumeric characters. Simulated aircraft noise was varied between levels of 95, 105 and 115 dB OASPL using a pink noise source. Results show that the addition of Sternberg's task and little effect on the intelligibility of the communication task while response time for the communication task increased.

Srinivasan, Srikanth

2010-01-01

The Mini Mental State Examination (MMSE) is widely used for dementia screening but has several shortcomings such as prominent ceiling effects, inadequate sensitivity to mild cognitive impairment, and uneven sampling of the major cognitive domains. In this study, we pilot a new dementia screening test - the Concise Cognitive Test (CONCOG) - designed to overcome the above short comings and describe the reliability measures and age, education, and gender effects. The CONCOG has a total score of 30, and has subtests for orientation, naming, registration, free recall and recognition of four words, semantic verbal fluency and copying. Participants were screened to exclude those with any neurological or psychiatric disease, simultaneously administered the CONCOG, and a Hybrid Mini Mental State Examination (HMMSE) adapted from Folstein's MMSE and Ganguli's Hindi Mental State Examination. The study sample had 204 subjects over the age of 60 years with a mean of 73 years and education level of 8 (4.5) years. Internal consistency for the CONCOG (Cronbach's alpha) was 0.74, inter-rater reliability (Kendall's tau-b) was 0.9, and the one-month test-retest reliability (Kendall's tau-b) was 0.7. Age and education level, but not gender, significantly influenced performance on both scales. Although the influence of age on the two scales was to a similar degree, the HMMSE was more affected by education than the CONCOG. Of 204 subjects, only 12 (5.7%) subjects obtained the maximum score on the CONCOG compared with 30 (14.1%) subjects on the HMMSE. The CONCOG took less than 10 minutes to complete in this sample. Age and education stratified norms are presented for the CONCOG. The CONCOG is a reliable cognitive screening measure. It has negligible ceiling effects, is less influenced by education compared with the HMMSE, and offers subscale scores for the major cognitive domains.

Data communications

Preckshot, G.G.

1993-08-01

The purpose of this paper is to recommend regulatory guidance for reviewers examining computer communication systems used in nuclear power plants. The recommendations cover three areas important to these communications systems: system design, communication protocols, and communication media. The first area, system design, considers three aspects of system design--questions about architecture, specific risky design elements or omissions to look for in designs being reviewed, and recommendations for multiplexed data communication systems used in safety systems. The second area reviews pertinent aspects of communication protocol design and makes recommendations for newly designed protocols or the selection of existing protocols for safety system, information display, and non-safety control system use. The third area covers communication media selection, which differs significantly from traditional wire and cable. The recommendations for communication media extend or enhance the concerns of published IEEE standards about three subjects: data rate, imported hazards and maintainability

Signification, communication, and the subject of desire

2008-11-01

Full Text Available Abstract Every product of design must evoke appropriate sensorial and symbolic resonances in the subjects to which it is offered, not simply by satisfying to their specific .rational. needs but mainly by appealing to their 'irrational' desires. Thus, a successful product is one that evokes a polymorphous, complex 'image' of itself in people's minds, onto which targeted subjects may project their respective desires. According to Lacan.s theories, therefore, any successful product is one that becomes a mediating sign between the conscious subject and his unconcious 'object' of desire, which means that products are consumed not merely for their 'objective' properties, as commodities, but as brands imbued with specific images and fantasies. Keywords: signification; desire; design Resumo Significação, comunicação e o sujeito do desejo - Todo produto de design precisa despertar ressonâncias sensoriais e simbólicas apropriadas nos sujeitos aos quais se oferece. Não simplesmente apelando para necessidades racionais específicas de seus consumidores em potencial, mas principalmente se dirigindo aos seus desejos. Por isso, qualquer produto de sucesso, de acordo com as teorias de Lacan, é aquele que se torna um signo mediador entre o sujeito consciente e seu inconsciente 'objeto' de desejo, o que significa que produtos não são simplesmente consumidos por suas propriedades 'objetivas', como mercadorias, mas como marcas, com imagens e fantasias específicas.

A Concise Introduction to Quantum Mechanics

Swanson, Mark S.

2018-02-01

Assuming a background in basic classical physics, multivariable calculus, and differential equations, A Concise Introduction to Quantum Mechanics provides a self-contained presentation of the mathematics and physics of quantum mechanics. The relevant aspects of classical mechanics and electrodynamics are reviewed, and the basic concepts of wave-particle duality are developed as a logical outgrowth of experiments involving blackbody radiation, the photoelectric effect, and electron diffraction. The Copenhagen interpretation of the wave function and its relation to the particle probability density is presented in conjunction with Fourier analysis and its generalization to function spaces. These concepts are combined to analyze the system consisting of a particle confined to a box, developing the probabilistic interpretation of observations and their associated expectation values. The Schrödinger equation is then derived by using these results and demanding both Galilean invariance of the probability density and Newtonian energy-momentum relations. The general properties of the Schrödinger equation and its solutions are analyzed, and the theory of observables is developed along with the associated Heisenberg uncertainty principle. Basic applications of wave mechanics are made to free wave packet spreading, barrier penetration, the simple harmonic oscillator, the Hydrogen atom, and an electric charge in a uniform magnetic field. In addition, Dirac notation, elements of Hilbert space theory, operator techniques, and matrix algebra are presented and used to analyze coherent states, the linear potential, two state oscillations, and electron diffraction. Applications are made to photon and electron spin and the addition of angular momentum, and direct product multiparticle states are used to formulate both the Pauli exclusion principle and quantum decoherence. The book concludes with an introduction to the rotation group and the general properties of angular momentum.

The feasibility of implementing a communication skills training course in pediatric hematology/oncology fellowship.

Weintraub, Lauren; Figueiredo, Lisa; Roth, Michael; Levy, Adam

Communication skills are a competency highlighted by the Accreditation Council on Graduate Medical Education; yet, little is known about the frequency with which trainees receive formal training or what programs are willing to invest. We sought to answer this question and designed a program to address identified barriers. We surveyed pediatric fellowship program directors from all disciplines and, separately, pediatric hematology/oncology fellowship program directors to determine current use of formal communication skills training. At our institution, we piloted a standardized patient (SP)-based communication skills training program for pediatric hematology/oncology fellows. Twenty-seven pediatric hematology/oncology program directors and 44 pediatric program directors participated in the survey, of which 56% and 48%, respectively, reported having an established, formal communication skills training course. Multiple barriers to implementation of a communication skills course were identified, most notably time and cost. In the pilot program, 13 pediatric hematology/oncology fellows have participated, and 9 have completed all 3 years of training. Precourse assessment demonstrated fellows had limited comfort in various areas of communication. Following course completion, there was a significant increase in self-reported comfort and/or skill level in such areas of communication, including discussing a new diagnosis (p =.0004), telling a patient they are going to die (p =.005), discussing recurrent disease (p communicating a poor prognosis (p =.002), or responding to anger (p ≤.001). We have designed a concise communication skills training program, which addresses identified barriers and can feasibly be implemented in pediatric hematology/oncology fellowship.

Communicating Health Risks under Pressure: Homeland Security Applications

International Nuclear Information System (INIS)

Garrahan, K.G.; Collie, S.L.

2006-01-01

The U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) Threat and Consequence Assessment Division (TCAD) within the National Homeland Security Research Center (NHSRC) has developed a tool for rapid communication of health risks and likelihood of exposure in preparation for terrorist incidents. The Emergency Consequence Assessment Tool (ECAT) is a secure web-based tool designed to make risk assessment and consequence management faster and easier for high priority terrorist threat scenarios. ECAT has been designed to function as 'defensive play-book' for health advisors, first responders, and decision-makers by presenting a series of evaluation templates for priority scenarios that can be modified for site-specific applications. Perhaps most importantly, the risk communication aspect is considered prior to an actual release event, so that management or legal advisors can concur on general risk communication content in preparation for press releases that can be anticipated in case of an actual emergency. ECAT serves as a one-stop source of information for retrieving toxicological properties for agents of concern, estimating exposure to these agents, characterizing health risks, and determining what actions need to be undertaken to mitigate the risks. ECAT has the capability to be used at a command post where inputs can be checked and communicated while the response continues in real time. This front-end planning is intended to fill the gap most commonly identified during tabletop exercises: a need for concise, timely, and informative risk communication to all parties. Training and customization of existing chemical and biological release scenarios with modeling of exposure to air and water, along with custom risk communication 'messages' intended for public, press, shareholders, and other partners enable more effective communication during times of crisis. For DOE, the ECAT could serve as a prototype that would be amenable to

Communicational Virtuality of Alterity (Otherness in the New Media

Aurel Codoban

2011-05-01

Full Text Available From the modernity which made communication secondary and dependent from knowledge and limited at the verbal type we inherited the idea that communication is in the first place a way of sending information. In this case the identity and otherness of the subjects that communicate are a clear and solid one. The postmodern and globalizing concept of communication put in the first place not the process of sending the information, but the building of relations. This ontological model of relationship describes the meaning of communicational reality as virtual, or, more precisely, describe communications action like a virtual reality. In this case the identity and otherness of the subjects that are in relation appear only as a weak occurrence of the modern idea of subject.

Neuner-Jehle, Stefan; Senn, Oliver; Wegwarth, Odette; Rosemann, Thomas; Steurer, Johann

2011-04-05

Patients understand information about risk better if it is communicated in numerical or visual formats (e.g. graphs) compared to verbal qualifiers only. How frequently different communication formats are used in clinical primary care settings is unknown. We collected socioeconomic and patient understanding data using questionnaires and audio-recorded consultations about cardiovascular disease risk. The frequencies of the communication formats were calculated and multivariate regression analysis of associations between communication formats, patient and general practitioner characteristics, and patient subjective understanding was performed. In 73% of 70 consultations, verbal qualifiers were used exclusively to communicate cardiovascular risk, compared to numerical (11%) and visual (16%) formats. Female GPs and female patient's gender were significantly associated with a higher use of verbal formats compared to visual formats (p=0.001 and p=0.039, respectively). Patient subjective understanding was significantly higher in visual counseling compared to verbal counseling (p=0.001). Verbal qualifiers are the most often used communication format, though recommendations favor numerical and visual formats, with visual formats resulting in better understanding than others. Also, gender is associated with the choice of communication format. Barriers against numerical and visual communication formats among GPs and patients should be studied, including gender aspects. Adequate risk communication should be integrated into physicians' education.

Grammar and Communication

Institute of Scientific and Technical Information of China (English)

刘辉

2007-01-01

Instead of being a boring subject, grammar is in fact one of the most exciting, creative, relevant subjects. It is sometimes described as the skeleton of a language, but it is much more than bones. It is the language's heartbeat, for without grammar; there can be no meaningful or effective communication. And grammar has different definitions and categories according to different contexts. By first reviewing the past linguists, especially those grammarians and their research, the paper makes some comparisons between some categories of grammar and puts forward that there is no 'good' or 'bad' grammar but knowing grammar or knowing about grammar really has a close relationship with effective communication.

DANCING AROUND THE SUBJECT WITH ROBOTS: ETHICAL COMMUNICATION AS A “TRIPLE AUDIOVISUAL REALITY”

Directory of Open Access Journals (Sweden)

Eleanor Sandry

2012-06-01

Full Text Available Communication is often thought of as a bridge between self and other, supported by what they have in common, and pursued with the aim of further developing this commonality. However, theorists such as John Durham Peters and Amit Pinchevski argue that this conception, connected as it is with the need to resolve and remove difference, is inherently ‘violent’ to the other and therefore unethical. To encourage ethical communication, they suggest that theory should instead support acts of communication for which the differences between self and other are not only retained, but also valued for the possibilities they offer. As a means of moving towards a more ethical stance, this paper stresses the importance of understanding communication as more than the transmission of information in spoken and written language. In particular, it draws on Fernando Poyatos’ research into simultaneous translation, which suggests that communication is a “triple audiovisual reality” consisting of language, paralanguage and kinesics. This perspective is then extended by considering the way in which Alan Fogel’s dynamic systems model also stresses the place of nonverbal signs. The paper explores and illustrates these theories by considering human-robot interactions because analysis of such interactions, with both humanoid and non-humanoid robots, helps to draw out the importance of paralanguage and kinesics as elements of communication. The human-robot encounters discussed here also highlight the way in which these theories position both reason and emotion as valuable in communication. The resulting argument – that communication occurs as a dynamic process, relying on a triple audiovisual reality drawn from both reason and emotion – supports a theoretical position that values difference, rather than promoting commonality as a requirement for successful communicative events. In conclusion, this paper extends this theory and suggests that it can form a basis

1984-01-01

An enzymatic synthesis of C-11 formaldehyde from C-11 methanol is presented, with immobilized alcohol oxidase and catalase: a rapid, simple procedure, with a high and reproducible yield. Carbon-11 methanol is oxidized to C-11 formaldehyde by passage over a column on which the enzymes alcohol oxidase and catalase are immobilized. The catalase increases reaction velocity by recycling the oxygen, and prevents destruction of the alcohol oxidase by eliminating the excess of hydrogen peroxide. The yield of the enzyme-catalyzed oxidation was 80-95%. A specific activity of 400-450 mCi/μmole was obtained at EOB + 20 min. Various immobilization techniques and the optimal reaction conditions of the immobilized enzymes are investigated

To assess the contribution of adrenal-derived androgens in women with hirsutism, adrenal scintigrams under dexamethasone suppression (DS) were performed on 35 women with increasing facial or body hair and irregular or absent menses. Based upon the DS regimen chosen (8 mg/d for 2 days or 4 md/d for 7 days before the injection of 6..beta..-(/sup 131/I)iodomethylnorcholesterol), three imaging patterns were identified. The first was the absence of uptake before 3 days (8-mg DS) or before 5 days (4-mg DS) after injection. This imaging pattern was seen in 17 of the 35 patients studied and was considered normal. The second pattern was bilateral uptake earlier than 3 days (8-mg DS regimen) or 5 days (4-mg DS) after injection. This was seen in 13 of the 35 patients and was interpreted as bilateral early visualization. Adrenal-vein catheterization performed on six patients with this pattern showed increased adrenal-vein testosterone. The third pattern, observed in five patients, was unilateral early visualization, which in four cases investigated to date was the result of an adrenocortical adenoma. This study confirms the adrenal cortex as a source of androgens in women with hirsutism and hyperandrogenism and demonstrates that DS adrenal scintigraphy can be utilized to identify those women in whom adrenal-derived androgens contribute to their hyperandrogenism.

Neural interface methods and apparatus to provide artificial sensory capabilities to a subject

Embodiments of neural interfaces according to the present invention comprise sensor modules for sensing environmental attributes beyond the natural sensory capability of a subject, and communicating the attributes wirelessly to an external (ex-vivo) portable module attached to the subject. The ex-vivo module encodes and communicates the attributes via a transcutaneous inductively coupled link to an internal (in-vivo) module implanted within the subject. The in-vivo module converts the attribute information into electrical neural stimuli that are delivered to a peripheral nerve bundle within the subject, via an implanted electrode. Methods and apparatus according to the invention incorporate implantable batteries to power the in-vivo module allowing for transcutaneous bidirectional communication of low voltage (e.g. on the order of 5 volts) encoded signals as stimuli commands and neural responses, in a robust, low-error rate, communication channel with minimal effects to the subjects' skin.

A Concise Dictionary of Transparency

Jakub Misun

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.

Resonant communicators, effective communicators. Communicator’s flow and credibility

Directory of Open Access Journals (Sweden)

Irene García-Ureta, Ph.D

2012-01-01

Full Text Available Communication studies have been integrating the latest developments in cognitive sciences and acknowledging the importance of understanding the subjective processes involved in communication. This article argues that communication studies should also take into account the psychology of the communicator. This article presents the theoretical basis and the results of a training programme designed for audiovisual communicators. The programme is based on the theories of self-efficacy and flow and seeks to improve students’ communication competencies through the use of presentation techniques and psychological skills to tackle communication apprehension. The programme involves an active methodology that is based on modelling, visualisation, immediate feedback and positive reinforcement. A repeated-measures ANOVA shows that the programme successfully decreases the level of communication apprehension, improves the perceived self-efficacy, improves the psychological state needed to perform better in front of the cameras (flow, and improves students’ communication skills. A path analysis proved that the perceived self-efficacy and anxiety levels predict the level of flow during the communication act. At the end of the training programme, those who experienced higher levels of flow and enjoyment during the communication task achieved higher quality levels in their communication exercise. It is concluded that the concepts of self-efficacy and flow facilitate advancing in the understanding of the factors that determine a communicator’s credibility and ability to connect with the audience.

The effects of electronic health records (EHRs) on doctor-patient communication are unclear. To evaluate the effects of EHR use compared with paper chart use, on novice physicians' communication skills. Within-subjects randomized controlled trial using observed structured clinical examination methods to assess the impact of use of an EHR on communication. A large academic internal medicine training program. First-year internal medicine residents. Residents interviewed, diagnosed, and initiated treatment of simulated patients using a paper chart or an EHR on a laptop computer. Video recordings of interviews were rated by three trained observers using the Four Habits scale. Thirty-two residents completed the study and had data available for review (61.5% of those enrolled in the residency program). In most skill areas in the Four Habits model, residents performed at least as well using the EHR and were statistically better in six of 23 skills areas (pcommunication score was better when using an EHR: mean difference 0.254 (95% CI 0.05 to 0.45), p = 0.012, Cohen's d of 0.47 (a moderate effect). Residents scoring poorly (>3 average score) with paper methods (n = 8) had clinically important improvement when using the EHR. This study was conducted in first-year residents in a training environment using simulated patients at a single institution. Use of an EHR on a laptop computer appears to improve the ability of first-year residents to communicate with patients relative to using a paper chart. © The Author 2014.

Rosemann Thomas

2011-04-01

Full Text Available Abstract Background Patients understand information about risk better if it is communicated in numerical or visual formats (e.g. graphs compared to verbal qualifiers only. How frequently different communication formats are used in clinical primary care settings is unknown. Methods We collected socioeconomic and patient understanding data using questionnaires and audio-recorded consultations about cardiovascular disease risk. The frequencies of the communication formats were calculated and multivariate regression analysis of associations between communication formats, patient and general practitioner characteristics, and patient subjective understanding was performed. Results In 73% of 70 consultations, verbal qualifiers were used exclusively to communicate cardiovascular risk, compared to numerical (11% and visual (16% formats. Female GPs and female patient's gender were significantly associated with a higher use of verbal formats compared to visual formats (p = 0.001 and p = 0.039, respectively. Patient subjective understanding was significantly higher in visual counseling compared to verbal counseling (p = 0.001. Conclusions Verbal qualifiers are the most often used communication format, though recommendations favor numerical and visual formats, with visual formats resulting in better understanding than others. Also, gender is associated with the choice of communication format. Barriers against numerical and visual communication formats among GPs and patients should be studied, including gender aspects. Adequate risk communication should be integrated into physicians' education.

Santos, Andrés

2016-01-01

This short primer offers non-specialist readers a concise, yet comprehensive introduction to the field of classical fluids – providing both fundamental information and a number of selected topics to bridge the gap between the basics and ongoing research. In particular, hard-sphere systems represent a favorite playground in statistical mechanics, both in and out of equilibrium, as they represent the simplest models of many-body systems of interacting particles, and at higher temperature and densities they have proven to be very useful as reference systems for real fluids. Moreover, their usefulness in the realm of soft condensed matter has become increasingly recognized – for instance, the effective interaction among (sterically stabilized) colloidal particles can be tuned to almost perfectly match the hard-sphere model. These lecture notes present a brief, self-contained overview of equilibrium statistical mechanics of classical fluids, with special applications to both the structural and thermodynamic pr...

Communicating shared knowledge in infancy.

Egyed, Katalin; Király, Ildikó; Gergely, György

2013-07-01

Object-directed emotion expressions provide two types of information: They can convey the expressers' person-specific subjective disposition toward objects, or they can be used communicatively as referential symbolic devices to convey culturally shared valence-related knowledge about referents that can be generalized to other individuals. By presenting object-directed emotion expressions in communicative versus noncommunicative contexts, we demonstrated that 18-month-olds can flexibly assign either a person-centered interpretation or an object-centered interpretation to referential emotion displays. When addressed by ostensive signals of communication, infants generalized their object-centered interpretation of the emotion display to other individuals as well, whereas in the noncommunicative emotion-expression context, they attributed to the emoting agent a person-specific subjective dispositional attitude without generalizing this attribution as relevant to other individuals. The findings indicate that, as proposed by natural pedagogy theory, infants are prepared to learn shared cultural knowledge from nonverbal communicative demonstrations addressed to them at a remarkably early age.

To examine the effect of gender on three key elements of communication with elderly individuals: effectiveness of the communication, perceived relevance to the individual, and effect of gender-stereotyped content. Survey. University of Connecticut Health Center. Thirty-three subjects (17 female); aged 69 to 91 (mean+/-standard deviation 82+/-5.4). Older adults listened to 16 brief narratives randomized in order and by the sex of the speaker (Narrator Voice). Effectiveness was measured according to ability to identify key features (Risks), and subjects were asked to rate the relevance (Plausibility). Number of Risks detected and determinations of plausibility were analyzed according to Subject Gender and Narrator Voice. Narratives were written for either sex or included male or female bias (Neutral or Stereotyped). Female subjects identified a significantly higher number of Risks across all narratives (P=.01). Subjects perceived a significantly higher number of Risks with a female Narrator Voice (P=.03). A significant Voice-by-Stereotype interaction was present for female-stereotyped narratives (P=.009). In narratives rated as Plausible, subjects detected more Risks (P=.02). Subject Gender influenced communication effectiveness. A female speaker resulted in identification of more Risks for subjects of both sexes, particularly for Stereotyped narratives. There was no significant effect of matching Subject Gender and Narrator Voice. This study suggests that the sex of the speaker influences the effectiveness of communication with older adults. These findings should motivate future research into the means by which medical providers can improve communication with their patients.

In this article, the definitions offered for religion, culture and communication and their relationship, using the literature governing the Intercultural Communication and Cross-cultural Communication as two subjects discussed in the field of Cultural Communication and International Communication, have been reviewed and tried through a novel method to promote the level of religion from a concept usually seen as something such as race, ethnic, identity and life style under the title of international communication and cultural communication to a much higher position and place it under the title of interreligious communication. Following creation of a new field of study, many of the scholars and thinkers who are concerned about that field get together and focus of its issues and try to offer definitions and divisions about the subject.

Visual communication and the content and style of conversation.

Science.gov (United States)

Rutter, D R; Stephenson, G M; Dewey, M E

1981-02-01

Previous research suggests that visual communication plays a number of important roles in social interaction. In particular, it appears to influence the content of what people say in discussions, the style of their speech, and the outcomes they reach. However, the findings are based exclusively on comparisons between face-to-face conversations and audio conversations, in which subjects sit in separate rooms and speak over a microphone-headphone intercom which precludes visual communication. Interpretation is difficult, because visual communication is confounded with physical presence, which itself makes available certain cues denied to audio subjects. The purpose of this paper is to report two experiments in which the variables were separated and content and style were re-examined. The first made use of blind subjects, and again compared the face-to-face and audio conditions. The second returned to sighted subjects, and examined four experimental conditions: face-to-face; audio; a curtain condition in which subjects sat in the same room but without visual communication; and a video condition in which they sat in separate rooms and communicated over a television link. Neither visual communication nor physical presence proved to be critical variable. Instead, the two sources of cues combined, such that content and style were influenced by the aggregate of available cues. The more cueless the settings, the more task-oriented, depersonalized and unspontaneous the conversation. The findings also suggested that the primary effect of cuelessness is to influence verbal content, and that its influence on both style and outcome occurs indirectly, through the mediation of content.

2015-10-01

This clinical focus article presents an illustration of a complex communication intervention, the Social Communication Intervention Programme (SCIP), as delivered to a child who has a social communication disorder (SCD). The SCIP intervention combined language processing and pragmatic and social understanding therapies in a program of individualized therapy activities and in close liaison with families. The study used an enhanced AB single-subject design in which an 8-year-old child with an SCD participated in 20 therapy sessions with a specialist speech-language pathologist. A procedure of matching assessment findings to intervention choices was followed to construct an individualized treatment program. Examples of intervention content and the embedded structure of SCIP are illustrated. Observational and formal measurements of receptive and expressive language, conversation, and parent-teacher ratings of social communication were completed before therapy, after therapy, and at a 6-month follow-up session. Outcomes revealed change in total and receptive language scores but not in expressive language. Conversation showed marked improvement in responsiveness, appreciation of listener knowledge, turn taking, and adaptation of discourse style. Teacher-reported outcomes included improved classroom behavior and enhanced literacy skills. Parent-reported outcomes included improved verbal interactions with family members and personal narratives. This clinical focus article demonstrates the complexity of needs in a child with an SCD and how these can be addressed in individualized intervention. Findings are discussed in relation to the essential nature of language support including pragmatic therapy for children with SCDs. Discussion of the role of formal and functional outcome measurement as well as the proximity of chosen outcomes to the intervention is included.

Schmidt, Allison M; Ranney, Leah M; Goldstein, Adam O

2014-12-04

Tobacco use, the leading cause of preventable death in the U.S., can be reduced through state-level tobacco prevention and cessation programs. In the absence of research about how to communicate the need for these programs to policymakers, this qualitative study aimed to understand the motivations and priorities of policymakers in North Carolina, a state that enacted a strong tobacco control program from 2003-2011, but drastically reduced funding in recent years. Six former legislators (three Democrats, three Republicans) and three lobbyists for health organizations were interviewed about their attitudes towards tobacco use, support of state-funded programs, and reactions to two policy briefs. Five themes emerged: (1) high awareness of tobacco-related health concerns but limited awareness of program impacts and funding, (2) the primacy of economic concerns in making policy decisions, (3) ideological differences in views of the state's role in tobacco control, (4) the impact of lobbyist and constituent in-person appeals, and (5) the utility of concise, contextualized data. These findings suggest that building relationships with policymakers to communicate ongoing program outcomes, emphasizing economic data, and developing a constituent advocacy group would be valuable to encourage continued support of state tobacco control programs.

INTERPERSONAL COMMUNICATION AND INTERSUBJECTIVE COMMUNICATION. SOME THEORETICAL AND CONCEPTUAL KEYS FOR ITS UNDERSTANDING

Directory of Open Access Journals (Sweden)

Marta Rizo Garcia

2014-09-01

Full Text Available In spite of the proliferation of digital communication forms, is urgent for communication research to strengthen the works around the interpersonal dimension of communicative processes. To do so, communication field needs to extend the boarding spectrum of interpersonal communication, an object that has been relegated to a secondary plane by the predominance of mass media research. This work is based on the need to distinguish intersubjective communication from interpersonal communication, two terms that are often conceived as synonymous. Even though both share the same empirical referents, their theoretical foundations are different. This essay presents three theoretical perspectives to define intersubjective communication –symbolic interactionism, phenomenological sociology and the Theory of Communicative Action– that share an interest beyond the situations of face to face interaction in which all subjects are daily immersed. A documentary and interpretive methodology is used in this work, because it's an argumentative essay that tries to outline some theoretical and conceptual guidelines to think –and make complex– interpersonal and intersubjective communication. It is relevant the approach of both communication types from different fields aside the strictly communicational; for that reason, in this essay are emphasized contributions made from other areas such as philosophy and social psychology.

Communication for Command and Control Systems provides a thorough exposition of the basic theoretical and practical features involved in the design of communication networks for command and control systems. This book focuses primarily on the practical side of computer-controlled communication. This text concentrates on the communication sides of the subject by surveying the means of transferring data between the various processing points and by appraising their potential advantages and possible defects in implementation. In this respect, this book should prove useful for the practicing enginee

Electrocortical activity associated with subjective communication with the deceased

Full Text Available During advanced meditative practices, unusual perceptions can arise including the sense of receiving information about unknown people who are deceased (discarnates. The reported experience of initiating mental communication with the deceased, may involve a state of consciousness similar to that achieved in contemplative meditation practices. As with meditation, this mental state involves calming mental chatter and becoming receptive to subtle feelings and sensations. Psychometric and brain electrophysiology data were collected from six individuals who had previously reported accurate information about discarnates under double-blind conditions. Each experimental participant performed two tasks with eyes closed. In the first task, the participant was given only the first name of a discarnate and asked 25 questions. After each question, the participant was asked to silently perceive information relevant to the question for 20 seconds so clean electro-encephalography data could be collected and then respond verbally. Responses were then transcribed and scored by individuals who knew the discarnates. Of the six participants, two could not be evaluated, and the four other participants scored higher than chance level (p<0.03 for 3 of the 4 participants. The correlation between accuracy and brain activity was significant in frontal theta for one participant (p < 0.01. In the second task, participants were asked to experience four mental states, each repeated three times for one minute: (1 Thinking about a known living person, (2 Listening to a biography, (3 Thinking about an imaginary person, and (4 Interacting mentally with a known discarnate. Statistically significant differences in electrocortical activity among the four conditions were obtained in all six participants, primarily at gamma frequencies. These differences suggest that the impression of communicating with the deceased may be a distinct mental state distinct from ordinary thinking or

The communicative performance of a severely hearing-impaired adolescent

1981-11-01

Full Text Available This study describes the communicative performance of a severely hearing-impaired adolescent.The experimenter taught the subject how to play Russian Backgammon. The subject conversed with, and afterwards taught his mother, speech therapist, and a peer how to play the game. Each dyad played the game once. Videotape recordings were made of each dyadic situation. The channels of communication, both verbal and nonverbal, used by each speaker, were determined. A relational communication coding scheme, involving the analysis of requests and subsequent responses, was applied to the data. Results indicate that the hearing-impaired adolescent, though not always able to hold a dominant position in a dyadic situation, was capable of expressing the same types of control as normal adults. Moreover, the types of control expressed varied as a function of each contextual setting. Whenever the subject did hold a dominant position, the combined verbal plus nonverbal channel was his predominant mode of  communication. These findings  suggest that a sociolinguistic approach provides important information regarding a hearing-impaired adolescent's communicative performance.

The distribution and elimination kinetics of Tc-99m pyridoxylidene glutamate (Tc-99m PG), of Tc-99m N-(2,6-dimethyl-phenylcarbamoylmethyl)iminodiacetic acid (Tc-99m HIDA), and of I-131 rose bengal in blood were quantitated after i.v. injection in rats. This was performed by use of a unique indwelling catheter that externalizes the systemic circulation, permitting continuous monitoring of blood radioactivity. The blood activity-time curves of Tc-99m PG and Tc-99m HIDA are described by the sum of three exponential functions. Only two exponentials are required in the case of I-131 rose bengal. The rank order for the rates of loss from blood was Tc-99m HIDA > Tc-99m PG > I-131 rose bengal. Bile was collected after administration of Tc-99m HIDA and Tc-99m PG. The total excretion of radioactivity over a 70-min period amounted to 65.7% and 42.8% of the dose of Tc-99m HIDA and Tc-99m PG, respectively. A linear compartmental kinetic model was developed to account for the disappearance from blood and the biliary excretion of these radiopharmaceuticals in rats

Source of Gallium-67 in gastrointestinal contents: concise communication

International Nuclear Information System (INIS)

Chen, D.C.; Scheffel, U.; Camargo, E.E.; Tsan, M.F.

1980-01-01

The sources of Ga-67 in gastrointestinal (GI) contents, and factors affecting its secretion were studied in rats. To prevent loss of fecal Ga-67, the anus was sutured before intravenous injection of Ga-67 citrate. Secretion of Ga-67 into the contents of the GI tract was rapid, 3, 6, and 9% of the injected dose were secreted at 1, 6, and 24 hr after injection, respectively. In contrast, Ga-67 concentration in the GI tissues remained relatively constant throughout this period. Analysis of Ga-67 contents of various parts of the GI tract revealed that small intestine is its major source, contributing 60% while the bile contributes 20%, large intestine 10%, esophagus and stomach 10%. Feeding had no effect on the Ga-67 secretion into GI contents. In contrast, the serum unbound iron-binding capacity (UIBC) played an important role in the GI secretion of Ga-67; reducing the serum UIBC reduced the Ga-67 secretion into GI contents

Transmedia Storytelling in Science Communication: One Subject, Multiple Media, Multiple Stories

Science.gov (United States)

Unger, M.; Moloney, K.

2012-12-01

Each communication medium has particular storytelling strengths. For example, video is particularly good at illustrating a progression of events, text at background and context, and games at describing systems. In what USC's Prof. Henry Jenkins described as "transmedia storytelling," multiple media are used simultaneously, in an expansive rather than repetitive way, to better tell a single, complex story. The audience is given multiple entry points to the story, and the story is exposed to diverse and dispersed audiences, ultimately engaging a broader public. We will examine the effectiveness of a transmedia approach to communicating scientific and other complex concepts to a broad and diverse audience. Using the recently developed Educational Visitor Center at the NCAR-Wyoming Supercomputing Center as a case study, we will evaluate the reach of various means of presenting information about the geosciences, climate change and computational science. These will include an assessment of video, mechanical and digital interactive elements, animated movie segments, web-based content, photography, scientific visualizations, printed material and docent-led activities.

Disorders of consciousness and communication. Ethical motivations and communication-enabling attributes of consciousness.

Science.gov (United States)

Tamburrini, Guglielmo; Mattia, Donatella

2011-01-01

Envisaged extensions of a functional magnetic resonance imaging (fMRI) technique allowing communication with patients affected by disorders of consciousness are here examined in connection with subjective symptom reporting, informed consent, and continued medical care decision-making. The principles of medical beneficence, personal autonomy protection, and the right to participate in social life are isolated as appropriate sources of ethical motivations for the use of fMRI-enabled communication. Consciousness requirements for each communication context are identified on the basis of qualitative distinctions between the access, phenomenal, and narrative varieties of consciousness. Ethically motivated uses of fMRI-enabled communication are hierarchically organized in terms of progressively more demanding consciousness requirements for successful communication. The outcomes of this analysis can be used to curb unrealistic expectations of these new scientific developments, and to promote mutual trust between medical doctors, patient surrogates and families.

Concise and Accessible Representations for Multidimensional Datasets: Introducing a Framework Based on the nD-EVM and Kohonen Networks

Directory of Open Access Journals (Sweden)

Ricardo Pérez-Aguila

2015-01-01

Full Text Available A new framework intended for representing and segmenting multidimensional datasets resulting in low spatial complexity requirements and with appropriate access to their contained information is described. Two steps are going to be taken in account. The first step is to specify (n-1D hypervoxelizations, n≥2, as Orthogonal Polytopes whose nth dimension corresponds to color intensity. Then, the nD representation is concisely expressed via the Extreme Vertices Model in the n-Dimensional Space (nD-EVM. Some examples are presented, which, under our methodology, have storing requirements minor than those demanded by their original hypervoxelizations. In the second step, 1-Dimensional Kohonen Networks (1D-KNs are applied in order to segment datasets taking in account their geometrical and topological properties providing a non-supervised way to compact even more the proposed n-Dimensional representations. The application of our framework shares compression ratios, for our set of study cases, in the range 5.6496 to 32.4311. Summarizing, the contribution combines the power of the nD-EVM and 1D-KNs by producing very concise datasets’ representations. We argue that the new representations also provide appropriate segmentations by introducing some error functions such that our 1D-KNs classifications are compared against classifications based only in color intensities. Along the work, main properties and algorithms behind the nD-EVM are introduced for the purpose of interrogating the final representations in such a way that it efficiently obtains useful geometrical and topological information.

Persuasion, Influence, and Value: Perspectives from Communication and Social Neuroscience.

Science.gov (United States)

Falk, Emily; Scholz, Christin

2018-01-04

Opportunities to persuade and be persuaded are ubiquitous. What determines whether influence spreads and takes hold? This review provides an overview of evidence for the central role of subjective valuation in persuasion and social influence for both propagators and receivers of influence. We first review evidence that decisions to communicate information are determined by the subjective value a communicator expects to gain from sharing. We next review evidence that the effects of social influence and persuasion on receivers, in turn, arise from changes in the receiver's subjective valuation of objects, ideas, and behaviors. We then review evidence that self-related and social considerations are two key inputs to the value calculation in both communicators and receivers. Finally, we highlight biological coupling between communicators and receivers as a mechanism through which perceptions of value can be transmitted.

Communicative performance of adolescents with severe speech impairment: influence of context.

Science.gov (United States)

Dalton, B M; Bedrosian, J L

1989-08-01

The communicative performance of 4 preoperational-level adolescents, using limited speech, gestures, and communication board techniques, was examined in a two-part investigation. In Part 1, each subject participated in an academic interaction with a teacher in a therapy room. Data were transcribed and coded for communication mode, function, and role. Two subjects were found to predominantly use the speech mode, while the remaining 2 predominantly used board and one other mode. The majority of productions consisted of responses to requests, and the initiator role was infrequently occupied. These findings were similar to those reported in previous investigations conducted in classroom settings. In Part 2, another examination of the communicative performance of these subjects was conducted in spontaneous interactions involving speaking and nonspeaking peers in a therapy room. Using the same data analysis procedures, gesture and speech modes predominated for 3 of the subjects in the nonspeaking peer interactions. The remaining subject exhibited minimal interaction. No consistent pattern of mode usage was exhibited across the speaking peer interactions. In the nonspeaking peer interactions, request predominated. In contrast, a variety of communication functions was exhibited in the speaking peer interactions. Both the initiator and the maintainer roles were occupied in the majority of interactions. Pertinent variables and clinical implications are discussed.

1980-01-01

Turnover of sodium in the human hand was studied by neutron activation. Patients suffering from various metabolic abnormalities affecting the skeleton, who were undergoing routine neutron activation for the measurement of calcium, were investigated along with a group of healthy volunteers. Neutron activation labels the sodium atoms simultaneously and with equal probability regardless of the turnover time of individual body compartments. The loss of sodium can be described either by a sum of two exponentials or by a single power function. Distinctions between patients and normal subjects were not apparent from the exponential model but were brought out by the power function. The exponent of time in the latter is a measure of clearance rate. The mean values of this parameter in (a) a group of patients suffering from acromegaly; (b) a group including Paget's disease, osteoporosis, Cushing's disease, and hyperparathyroidism; and (c) a group of healthy subjects, were found to be significantly different from each other

Eriksson, Karin; Forsgren, Emma; Hartelius, Lena; Saldert, Charlotta

2016-01-01

To evaluate the effect of a communication partner training programme directed to enrolled nurses working with people with communication disorders in nursing homes, using an individualised approach. Five dyads consisting of a person with stroke-induced aphasia (n = 4) or Parkinson's disease (PD) (n = 1) living in different nursing homes and his/her enrolled nurse participated in the study, which had a replicated single-subject design with multiple baselines across individuals. The main element of the intervention was supervised analysis of video-recorded natural interaction in everyday nursing situations and the formulation of individual goals to change particular communicative strategies. Outcome was measured via blinded assessments of filmed natural interaction obtained at baseline, intervention and follow-up and showed an increased use of the target communicative strategies. Subjective measures of goal attainment by the enrolled nurses were consistent with these results. Measures of perceived functional communication on behalf of the persons with communication disorders were mostly positive; four of five participants with communication disorders and two of five enrolled nurses reported improved functional communication after intervention. The use of an individualised communication partner training programme led to significant changes in natural interaction, which contributes importantly to a growing body of knowledge regarding communication partner training. Communication partner training can improve the communicative environment of people with communication disorders. For people with communication disorders who live in institutions, the main conversation partner is likely to be a professional caretaker. An individualised approach for communication partner training that focussed on specific communication patterns was successful in increasing the use of supportive strategies that enrolled nurses used in natural interaction with persons with communication disorders

High volume surges in health care are uncommon and unpredictable events. Their impact on health system performance and capacity is difficult to study. To identify time periods that exhibited very busy conditions at a poison control center and to determine whether cases and communication during high volume call periods are different from cases during low volume periods. Call data from a US poison control center over twelve consecutive months was collected via a call logger and an electronic case database (Toxicall®).Variables evaluated for high call volume conditions were: (1) call duration; (2) number of cases; and (3) number of calls per staff member per 30 minute period. Statistical analyses identified peak periods as busier than 99% of all other 30 minute time periods and low volume periods as slower than 70% of all other 30 minute periods. Case and communication characteristics of high volume and low volume calls were compared using logistic regression. A total of 65,364 incoming calls occurred over 12 months. One hundred high call volume and 4885 low call volume 30 minute periods were identified. High volume periods were more common between 1500 and 2300 hours and during the winter months. Coded verbal communication data were evaluated for 42 high volume and 296 low volume calls. The mean (standard deviation) call length of these calls during high volume and low volume periods was 3 minutes 27 seconds (1 minute 46 seconds) and 3 minutes 57 seconds (2 minutes 11 seconds), respectively. Regression analyses revealed a trend for fewer overall verbal statements and fewer staff questions during peak periods, but no other significant differences for staff-caller communication behaviors were found. Peak activity for poison center call volume can be identified by statistical modeling. Calls during high volume periods were similar to low volume calls. Communication was more concise yet staff was able to maintain a good rapport with callers during busy call periods

The absorbed radiation dose that would result from the oral or intravenous administration of SeHCAT (23-[ 75 Se]selena-25-homotaurocholate) has been calculated using the MIRD tables and formulas and data from measurements of whole-body distribution and from long-term whole-body counting in rats, mice, and man. When SeHCAT is administered to normal subjects, the gallbladder is the critical organ, receiving 12 mrad (oral dose) or 22 mrad (i.v.) per microcurie. The whole-body dose is 1 mrad/μCi, whatever the route of administration. In severe hepatic failure the liver might receive 200 mrad/μCi. The activity likely to be used in routine clinical practice is 10 μCi. Where a whole-body counter is used, an activity of 1 μCi has proved adequate. Even at an administered activity of 25 μCi, the absorbed dose is small compared with established techniques of investigating the gastrointestinal tract

Full Text Available Background Fulfilling the learners' "real needs" will improve medical education. There are subjects that are necessary for any clinical residents not considering their field of specialty. Among the subjects ten seems to be the most important: research methodology and data analysis, computer-based programs, medical recording, cardiopulmonary and cerebral resuscitation, clinical teaching programs, communication skills, clinical ethics, laboratory examinations, reporting special diseases and death certification, and prescription. Purpose This cross-sectional study assessed educational needs of clinical residents for ten educational subjects. Methods A questionnaire prepared by board faculty members consisted of 10 close-ended questions, and one open­ ended question was distributed among 1307 residents from 22 clinical disciplines, who registered for preboard or promotion exam in June 2000. Results Among the subjects three were the most needed: computer-based programs 149 (60%, data collecting system 606 (49%, and clinical ethics 643 (46%. The prescription standard was the least required 177(13%. Conclusion Complementary training courses on these subjects can be an answer to the clinical residents needs.

Scolobig, A.

2015-06-01

Inadequate, misinterpreted, or missing risk and crisis communication may be a reason for practitioners, and sometimes science advisors, to become the subjects of criminal investigations. This work discusses the legal consequences of inadequate risk communication in these situations. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks, and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

INTERCULTURAL COMMUNICATION IN TOURISM

Cristina Elena ALBU

2015-06-01

Full Text Available Communication is involved in all social life acts, being the constituent factor of creation and of cultural processes. Cultural diversity and intercultural dialogue are intensely discussed topics in today's society which is marked by globalization. Cultural differences are the core subject for studies addressing intercultural communication. Good knowledge of other cultures is a necessary step to get to recognize the nature of these differences and to relate to others through attitudes of understanding and tolerance which are premises for genuine intercultural dialogue, especially in the tourism industry. While communication is an act of human relationships, culture is the motive of this act. In tourism, quality of communication is related to the level of the culture involved and to the degree of improvement of the means of which is done. Intercultural communication experiences help tourists to know and to appreciate other cultures, but also help them to a better understanding of their own culture.

Zhou, Xue Mei; Jia, Shu Hua

2012-11-01

Recognizing suicidal communication from the distressful catharsis in a high-risk group with suicidal tendencies is essential for suicide prevention. This study analyzes whether suicidal communication can indicate the severity of suicidal intent. Various types of suicidal communication are defined, and their clinical significance is further explored. A comprehensive analysis of the psychological autopsy data of 200 victims of completed suicide, including their general socio-demographic status, suicidal communication methods, previous suicide attempts, mental disorders, and psychosocial situation. Our results showed that 39.5% of all the subjects were suicidal communicators, 23.0% had previously attempted suicide, and 14.0% left suicide notes; 32.4% of 142 subjects free of physical disease suffered from mental disorders. Suicidal communication included verbal communication, behavioral communication, and suicidal notes. Younger people with a higher level of education were more inclined to communicate their suicidal intent by leaving a suicide note. Suicide notes, but not previous suicide attempts or psychosocial situation, were significantly correlated with suicidal intent. Suicidal communicators showed higher depression scores than non-communicators. Those who suffered from mood disorders with higher levels of both depression and suicidal intent were more likely to expose their intent through behavioral communication. The present study provides strong evidence that suicidal communication can indicate the severity of suicidal intent. Current findings help interpret high-risk, self-destructive behavior and consequently provide the theoretical basis for a feasible suicide prevention program.

Communication of Pulmonary Function Test Results: A Survey of Patient's Preferences.

Directory of Open Access Journals (Sweden)

Debbie Zagami

Full Text Available Physician-patient communication in patients suffering from common chronic respiratory disease should encompass discussion about pulmonary function test (PFT results, diagnosis, disease education, smoking cessation and optimising inhaler technique. Previous studies have identified that patients with chronic respiratory disease/s often express dissatisfaction about physician communication. Currently there is a paucity of data regarding patient awareness of their PFT results (among those who have undergone PFTs previously or patient preferences about PFT result communication.We undertook a three-month prospective study on outpatients referred to two Pulmonary Function Laboratories. If subjects had undergone PFTs previously, the awareness of their previous test results was evaluated. All subjects were asked about their preferences for PFT result communication. Subjects were determined to have chronic respiratory disease based on their past medical history.300 subjects (50% male with a median age (± SD of 65 (± 14 years participated in the study. 99% of the study participants stated that they were at least moderately interested in knowing their PFT results. 72% (217/300 of the subjects had undergone at least one PFT in the past, 48% of whom stated they had not been made aware of their results. Fewer subjects with chronic respiratory disease preferred that only a doctor discuss their PFT results with them (28% vs. 41%, p = 0.021.Our study demonstrates that while almost all subjects want to be informed of their PFT results, this does not occur in a large number of patients. Many subjects are agreeable for their PFT results to be communicated to them by clinicians other than doctors. Further research is required to develop an efficient method of conveying PFT results that will improve patient satisfaction and health outcomes.

Full Text Available Tobacco use, the leading cause of preventable death in the U.S., can be reduced through state-level tobacco prevention and cessation programs. In the absence of research about how to communicate the need for these programs to policymakers, this qualitative study aimed to understand the motivations and priorities of policymakers in North Carolina, a state that enacted a strong tobacco control program from 2003–2011, but drastically reduced funding in recent years. Six former legislators (three Democrats, three Republicans and three lobbyists for health organizations were interviewed about their attitudes towards tobacco use, support of state-funded programs, and reactions to two policy briefs. Five themes emerged: (1 high awareness of tobacco-related health concerns but limited awareness of program impacts and funding, (2 the primacy of economic concerns in making policy decisions, (3 ideological differences in views of the state’s role in tobacco control, (4 the impact of lobbyist and constituent in-person appeals, and (5 the utility of concise, contextualized data. These findings suggest that building relationships with policymakers to communicate ongoing program outcomes, emphasizing economic data, and developing a constituent advocacy group would be valuable to encourage continued support of state tobacco control programs.

Full Text Available The European Higher Education Area promotes the integration of new technologies in didactic innovation and it aims to improve skills. It has been requested by students at the Complutense University of Madrid, who have a digital native profile or millennial. This article is a study about implementation of immersive virtual reality in the practical part of the subjects related to business communication. Specifically, it applied in the subject Crisis Communication. The methodology is a survey and three focus groups for professors and students. The conclusions say that the implementation of immersive virtual reality improves the expectations and interest of students. It also improves the skills acquired and the practical part of the subjects of communication improve employment of students of the Degree, which is one of their main causes of dissatisfaction. The full implementation of mobile telephony suggests using virtual reality devices adapted to them rather than “caves” (C.A.V.E. or consoles.

Communicative versus strategic rationality: Habermas theory of communicative action and the social brain.

Science.gov (United States)

Schaefer, Michael; Heinze, Hans-Jochen; Rotte, Michael; Denke, Claudia

2013-01-01

In the philosophical theory of communicative action, rationality refers to interpersonal communication rather than to a knowing subject. Thus, a social view of rationality is suggested. The theory differentiates between two kinds of rationality, the emancipative communicative and the strategic or instrumental reasoning. Using experimental designs in an fMRI setting, recent studies explored similar questions of reasoning in the social world and linked them with a neural network including prefrontal and parietal brain regions. Here, we employed an fMRI approach to highlight brain areas associated with strategic and communicative reasoning according to the theory of communicative action. Participants were asked to assess different social scenarios with respect to communicative or strategic rationality. We found a network of brain areas including temporal pole, precuneus, and STS more activated when participants performed communicative reasoning compared with strategic thinking and a control condition. These brain regions have been previously linked to moral sensitivity. In contrast, strategic rationality compared with communicative reasoning and control was associated with less activation in areas known to be related to moral sensitivity, emotional processing, and language control. The results suggest that strategic reasoning is associated with reduced social and emotional cognitions and may use different language related networks. Thus, the results demonstrate experimental support for the assumptions of the theory of communicative action.

Parent-Adolescent Sexual and Reproductive Health Communication Is Very Limited and Associated with Adolescent Poor Behavioral Beliefs and Subjective Norms: Evidence from a Community Based Cross-Sectional Study in Eastern Ethiopia.

Directory of Open Access Journals (Sweden)

Yadeta Dessie

Full Text Available While parent-adolescent sexual and reproductive health (SRH communication is one potential source of SRH information for adolescents, it appears to be inadequately practiced in Ethiopia. This study was designed to investigate the factors that limit or improve parent-adolescent SRH communication in Harar, Eastern Ethiopia.A community based cross-sectional study was done on 4,559 adolescents of age 13-18. SRH communication was measured using a nine-item scale whose response ranged from "not at all" to "always." Summated composite score ranging from 0-36 was generated; higher score indicates high SRH communication. A median value of the composite score was 4 out of the possible 36 with an Interquartile Range (IQR of 7. Respondents were ranked as very poor, poor and satisfactory communicators based on 33rd and 67th percentiles values. Generalized ordered logit model was applied to investigate the factors associated with SRH communication.Results showed that the adolescents who were more likely to practice poor-very poor/very poor SRH communication were those who had poor behavioral beliefs on and poor subjective norms of communicating sexual issues with parents and those who perceived their parents' reproductive health (RH knowledge as poor. Nonetheless, the probability of poor-very poor/very poor SRH communication was less with high adolescent-parent communication quality, television co-viewing and discussions, and self-disclosure.Curtailing the adolescents' underlying poor beliefs and norms, and improving adolescent-parent communication quality, self-disclosure, and television co-viewing and discussions are essential to engage the parents in sexual and reproductive health education of the adolescents.

Multimedia Astronomy Communication: Effectively Communicate Astronomy to the Desired Audience

Science.gov (United States)

Star Cartier, Kimberly Michelle; Wright, Jason

2017-01-01

A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

Interdisciplinary Communication

Nagib Callaos

2013-12-01

Full Text Available Communication is fundamental in scientific practice and an integral part of academic work. The practice of communication cannot be neglected by those who are trying to advance scientific research. Effective means should continuously be identified in order to open channels of communication within and among disciplines, among scientists and between scientists and the general public.[1]The increasing importance of interdisciplinary communication has been pointed out by an increasing number of researchers and scholars, as well as in conferences and roundtables on the subject. Some authors even estimate that "interdisciplinary study represents the future of the university."[2] Since interdisciplinary study is "the most underthought critical, pedagogical and institutional concept in modern academy"[3] it is important to think and reflect, and even do some research, on this concept or notion. Research and practice based reflections with regards to this issue are important especially because the increasing complexity and proliferation of scientific research is generating countless specialties, sub-specialties and sub-sub-specialties, with their respective special languages; which were "created for discrete local areas of research based upon the disconnected branches of science."[4] On the other hand, scientific, technical and societal problems are requiring multi- or inter-disciplinary consideration. Consequently, interdisciplinary communication channels are being needed with urgency, and scientific research should be integrated, not just in the context of its discipline, but also in the context of related disciplines. Much more reflection and research should be done on this issue. Research on adequate research integration and communication is urgently required, i.e. meta-research efforts should be done in order to relate research results in an adequate and more useful way. This meta-research effort might be done in the context of each particular

Risk Communication has shown its importance in the elaboration of emergency plans in the Chemical industry. In the 90's, the UNEP developed the APELL (Awareness and Preparedness for Emergency at Local Level) plan, a risk management methodology used by dangerous chemical facilities. The methodology comprises the commitment of both Government and the community located in the risk area in the development of the emergency plan. In the nuclear sector, there is no similar methodology developed so far. However, establishing a communication channel between the nuclear segment and the community is essential. In Brazil, the construction of Angra 3 and the RMB (Multi Purpose Reactor) project stand as nuclear initiatives that improve the importance of a good communication to the public. Security issues of these projects are natural sources of concernment to the public, which is aggravated by events such as the Fukushima disaster. Without an effective communication about what means the presence of nuclear plants and reactors in a specific area, the interested public will only have an alarmist vision of the subject, given by those against these facilities.

Communication of autistic children. To assess the communication functionality of verbal and non-verbal children of the autistic spectrum and to identify possible associations amongst the groups. Subjects were 20 children of the autistic spectrum divided into two groups: V with 10 verbal children and NV with 10 non-verbal children with ages varying between 2y10m and 10y6m. All subjects were video recorded during 30 minutes of spontaneous interaction with their mothers. The samples were analyzed according to the functional communicative profile and comparisons within and between groups were conducted. Data referring to the occupation of communicative space suggest that there is an even balance between each child and his mother. The number of communicative acts per minute shows a clear difference between verbal and non-verbal children. Both verbal and non-verbal children use mostly the gestual communicative mean in their interactions. Data about the use of interpersonal communicative functions point out to the autistic children's great interactive impairment. The characterization of the functional communicative profile proposed in this study confirmed the autistic children's difficulties with interpersonal communication and that these difficulties do not depend on the preferred communicative mean.

2016-04-01

The number of foreign doctors in Germany has increased steadily in recent years. To obtain the German medical license, sufficient language competence is mandatory. Nevertheless, in practice, foreign doctors have considerable difficulties in their communication with patients, medical colleagues and other health professionals. This can lead to misunderstandings and thus impair patient safety. To overcome this problem, the "patient communication test" was developed and piloted as an additional requirement to be granted license to practice medicine in Germany. The aim of this study is to present our results in the development and piloting of this test. 3 OSCE stations (Objective Structured Clinical Examination) were designed, which evaluate communication skills in 3 medical competences: history taking, case presentation and explaining to patients before obtaining informed consent. After extensive instruction of actors as patients and raters on the basis of the evaluation criteria, the communication test was subjected to pilot studies in 6 different cities (Freiburg, Jena, Mainz, Mannheim, Tübingen, and Ulm). In 2013, 639 foreign doctors participated in the test; 461 (72.14%) of these doctors passed the test on their first try, 51 (7.98%) on their second attempt and 6 (0.93%) on their third try. The patient communication test evaluates the communication skills of foreign doctors in OSCE-setting using standardized actor-patients. This improves the communication skills and enhances patient safety in the German health care system by smooth inter-professional and patient-centered communication. © Georg Thieme Verlag KG Stuttgart · New York.

Concise Stereocontrolled Formal Synthesis of (±)-Quinine and Total Synthesis of (±)-7-Hydroxyquinine via Merged Morita-Baylis-Hillman-Tsuji-Trost Cyclization

Science.gov (United States)

Webber, Peter; Krische, Michael J.

2010-01-01

Concise stereoselective syntheses of (±)-quinine and (±)-7-hydroxyquinine are achieved using a catalytic enone cycloallylation that combines the nucleophilic features of the Morita-Baylis-Hillman reaction and the electrophilic features of the Tsuji-Trost reaction. Cyclization of enone-allyl carbonate 11 delivers the product of cycloallylation 13 in 68% yield. Diastereoselective conjugate reduction of the enone 13 (>20:1 dr) followed by exchange of N-protecting groups provides the saturated N-Boc-protected methyl ketone 19, which upon aldol dehydration provides quinoline containing enone 15, possessing all carbon atoms of quinine. Exposure of ketone 15 to L-selectride enables diastereoselective carbonyl reduction (>20:1 dr) to furnish the allylic alcohol 16. Stereoselective hydroxyl-directed epoxidation using an oxovanadium catalyst modified by N-hydroxy-N-Me-pivalamide delivers epoxide 17 (17:1 dr). Cyclization of the resulting amine-epoxide 17 provides (±)-7-hydroxyquinine in 13 steps and 11% overall yield from aminoacetaldehyde diethyl acetal. Notably, highly stereoselective formation of five contiguous stereocenters is achieved through a series of 1,2-asymmetric induction events. A formal synthesis of (±)-quinine is achieved upon deoxygenation of the N-Cbz-protected allylic acetate 22 to provide olefin 23, which previously has been converted to quinine. Thus, (±)-quinine is accessible in 16 steps and 4% overall yield from commercial aminoacetaldehyde diethyl acetal, making this route the most concise approach to quinine, to date. PMID:18989927

The Need for More Scientific Approaches to Science Communication

Science.gov (United States)

Sadri, S.

2015-12-01

Two possible goals for public science communication are: a) improving the public's in-depth understanding of the scientific subject; and b) fostering the public's belief that scientific efforts make a better world. Although (a) is often a natural target when scientists try to communicate their subject, the importance of (b) is underscored by the NSF, who investigated the "cultural authority of science" to understand science's role in policymaking. Surveys consistently find that there is a huge divergence between "knowledge" and "admiration" of science in society because science literacy has very little to do with public perception of science. However, even if both goals could be achieved, it doesn't necessarily mean that the general public will act on scientific advice. Different parts of society have different criteria for reaching judgments about how to act in their best interests. This makes the study of science communication important when controversies arise requiring public engagement. Climate change, sustainability, and water crises are only a few examples of such controversial subjects. Science communication can be designed carefully to sponsor dialogue and participation, to overcome perceptual obstacles, and to engage with stakeholders and the wider public. This study reviews work in social science that tries to answer: When is science communication necessary? What is involved in science communication? What is the role of media in effective science communication? It also reviews common recommendations for improved public engagement by scientists and science organizations. As part of this effort, I will present some portions of my science films. I will conclude with suggestions on what scientific institutions can focus on to build trust, relationships, and participation across segments of the public. Keywords: informal learning, popular science, climate change, water crisis, science communication, science films, science policy.

Brain mechanisms underlying human communication

2009-07-01

Full Text Available Human communication has been described as involving the coding-decoding of a conventional symbol system, which could be supported by parts of the human motor system (i.e. the “mirror neurons system”. However, this view does not explain how these conventions could develop in the first place. Here we target the neglected but crucial issue of how people organize their non-verbal behavior to communicate a given intention without pre-established conventions. We have measured behavioral and brain responses in pairs of subjects during communicative exchanges occurring in a real, interactive, on-line social context. In two fMRI studies, we found robust evidence that planning new communicative actions (by a sender and recognizing the communicative intention of the same actions (by a receiver relied on spatially overlapping portions of their brains (the right posterior superior temporal sulcus. The response of this region was lateralized to the right hemisphere, modulated by the ambiguity in meaning of the communicative acts, but not by their sensorimotor complexity. These results indicate that the sender of a communicative signal uses his own intention recognition system to make a prediction of the intention recognition performed by the receiver. This finding supports the notion that our communicative abilities are distinct from both sensorimotor processes and language abilities.

The application of digital image processing to improve man-machine communication in a nuclear reactor control room is illustrated. At the Hanford N Reactor, operated by UNC Nuclear Industries for the United States Department of Energy, in Richland, Washington, digital image processing is applied to flow, temperature, and tube power data. Color displays are used to present the data in a clear and concise fashion. Specific examples are used to demonstrate the capabilities and benefits of digital image processing of reactor data. N Reactor flow and power maps for routine reactor operations and for perturbed reactor conditions are displayed. The advantages of difference mapping are demonstrated. Image processing techniques have also been applied to results of analytical reactor models; two examples are shown. The potential of combining experimental and analytical information with digital image processing to produce predictive and adaptive reactor core models is discussed. The applications demonstrate that digital image processing can provide new more effective ways for control room personnel to assess reactor status, to locate problems and explore corrective actions. 10 figures

Predicting BCI subject performance using probabilistic spatio-temporal filters.

Directory of Open Access Journals (Sweden)

Heung-Il Suk

Full Text Available Recently, spatio-temporal filtering to enhance decoding for Brain-Computer-Interfacing (BCI has become increasingly popular. In this work, we discuss a novel, fully Bayesian-and thereby probabilistic-framework, called Bayesian Spatio-Spectral Filter Optimization (BSSFO and apply it to a large data set of 80 non-invasive EEG-based BCI experiments. Across the full frequency range, the BSSFO framework allows to analyze which spatio-spectral parameters are common and which ones differ across the subject population. As expected, large variability of brain rhythms is observed between subjects. We have clustered subjects according to similarities in their corresponding spectral characteristics from the BSSFO model, which is found to reflect their BCI performances well. In BCI, a considerable percentage of subjects is unable to use a BCI for communication, due to their missing ability to modulate their brain rhythms-a phenomenon sometimes denoted as BCI-illiteracy or inability. Predicting individual subjects' performance preceding the actual, time-consuming BCI-experiment enhances the usage of BCIs, e.g., by detecting users with BCI inability. This work additionally contributes by using the novel BSSFO method to predict the BCI-performance using only 2 minutes and 3 channels of resting-state EEG data recorded before the actual BCI-experiment. Specifically, by grouping the individual frequency characteristics we have nicely classified them into the subject 'prototypes' (like μ - or β -rhythm type subjects or users without ability to communicate with a BCI, and then by further building a linear regression model based on the grouping we could predict subjects' performance with the maximum correlation coefficient of 0.581 with the performance later seen in the actual BCI session.

Sexual communication among young adult heterosexual Latinos: a qualitative descriptive study.

Science.gov (United States)

Alvarez, Carmen Paula; Villarruel, Antonia

2013-01-01

Sexual communication between sexual partners is an important component in prevention efforts against unintended consequences of sex. The purpose of this study was to describe sexual communication among young adult Latinos. Four semistructured, sex-segregated focus groups were used for this study. Participants (N = 20) were 18-30 years old self-identified Latinos who were in heterosexual and sexually active relationships (more than 3 months). Participants revealed that initial sexual communication with their partners was avoided related to a lack of interest in a partner's sexual history, feeling embarrassed about the topic, or concern for offending one's partner or partner's family. As a result of these beliefs and attitudes, initial sexual communication was nonverbal and focused on sexual pleasure. After the initiation of sexual activity, verbal sexual communication expanded to include sexual history. These findings highlight the importance of attitudes and subjective norms toward verbal sexual communication. Attitudes and subjective norms toward sexual communication in the context of a romantic relationship and how it may impact sexual behavior in the relationship should be further explored.

Albumin microspheres labeled with Ga-67 by chelation: concise communication

International Nuclear Information System (INIS)

Hnatowich, D.J.; Schlegel, P.

1981-01-01

Albumin microspheres have been synthesized with EDTA and DTPA chelating groups covalently bound to their surface. The microspheres may be labeled with Ga-67 at high yield (97 +- 2%) by transcomplexation from a 0.1 M Ga-67 acetate solution. With EDTA microspheres the resulting label dissociates only slightly after 24 hr in 50% plasma at 37 0 C, whereas with DTPA microspheres the label shows no detectable dissociation over this period. By contrast, microspheres without chelating groups lose their label virtually completely under these conditions. Following intravenous administration of sized Ga-67 DTPA microspheres in mice, about (84 +- 16)% of the activity localizes in the lungs at 5 min, with (60 +- 7)% remaining after 2 h. Since labeling is by chelation, the microspheres may also be tagged with other metallic radionuclides

The results are compared with other known prognostic parameters and with a predictive index formulated from a prior multiparametric analysis performed in 352 cases. In 47 cases parallel abnormality of Tc and In uptakes was noted and was well correlated with other prognostic factors. Indium uptake is apparently a good indicator of the severity of aplasia; extension of active erythroid tissue, demonstrated with this method, is correlated with prognosis. In nine cases, excessive in uptake is explained by dyserythropoiesis associated with granulo- and thrombocytopenia (Fanconi's anemia in most cases). In 20 of our patients, TcSC uptake was excessive compared with that of In and with other prognostic factors. Statistically, this phenomenon carries an unfavorable prognosis but its physiological meaning remains to be defined

Total body Tc-99m pyrophosphate scintigraphy was performed on 11 ''ultramarathon'' runners to assess the ability of nuclear medicine techniques to evaluate skeletal-muscle injury due to exercise. We found increased muscle radionuclide concentration in 90% of the runners. The pattern of muscle uptake correlated with the regions of maximum pain. The detection of exercise-induced rhabdomyolysis appeared to be best when scintigraphy was performed within 48 hr after the race, and to be almost undetectable after about a week. It was possible to differentiate muscle injury from joint and osseous abnormalities such as bone infarct or stress fracture. Although 77% of the runners had elevated serum creatine kinase MB activity, cardiac scintigraphy showed no evidence of myocardial injury

We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T 3 -RU, T 3 , T 4 , TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06

Sodium bicarbonate was used to enhance the myocardial concentration of Tl-201 in rabbits and dogs. Organ distribution studies in rabbits and in vivo imaging in dogs showed a 1.5 to 2-fold increase in myocardial Tl-201 concentration in bicarbonate-treated animals as compared with matched controls. Image improvement was noted, with threefold enhancement of myocardium-to-liver ratios. The results suggest that a similar improvement may be possible for clinical myocardial imaging

Clinical trials are essential for developing new and effective treatments and improving patient quality of life; however, many trials cannot answer their primary research questions because they fall short of their recruitment goals. This article reports the results of formative research conducted in two populations, the public and primary care physicians, to identify messages that may raise awareness and increase interest in clinical trials and be used in a national communication campaign. Results suggested that participants were primarily motivated to participate in clinical trials out of a self-interest to help themselves first. Messages illustrated that current treatments were tested via clinical trials, helped normalize trials as routine practices, and reduced concerns over trying something new first. Participants wanted messages that portray trials as state-of-the-art choices that offer some hope, show people like themselves, and are described in a clear, concise manner with actionable steps for them to take. The study revealed some differences in message salience, with healthy audiences exhibiting lower levels of interest. Our results suggest that targeted messages are needed, and that communication with primary health-care providers is an important and necessary component in raising patient awareness of the importance of clinical trials.

The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates. A survey of relevant anti-rotavirus IgY basic studies and clinical trials among neonatal animals (since 1994-2015) and humans (since 1982-2015) have been reviewed and briefly summarized. Our analysis of a number of rotavirus investigations involving animal and human clinical trials revealed that anti-rotavirus IgY significantly reduced the severity of clinical manifestation of diarrhea among IgY-treated subjects relative to a corresponding control or placebo group. The accumulated information as a whole depicts oral IgY to be a safe and efficacious option for treatment of rotavirus diarrhea in neonates. There is however a clear need for more randomized, placebo controlled and double-blind trials with bigger sample size to further solidify and confirm claims of efficacy and safety in controlling diarrhea caused by rotavirus infection especially among human infants with health issues such as low birth weights or compromised immunity in whom it is most needed.

How can we identify and communicate the ecological value of deep-sea ecosystem services?

Jobstvogt, Niels; Townsend, Michael; Witte, Ursula; Hanley, Nick

2014-01-01

Submarine canyons are considered biodiversity hotspots which have been identified for their important roles in connecting the deep sea with shallower waters. To date, a huge gap exists between the high importance that scientists associate with deep-sea ecosystem services and the communication of this knowledge to decision makers and to the wider public, who remain largely ignorant of the importance of these services. The connectivity and complexity of marine ecosystems makes knowledge transfer very challenging, and new communication tools are necessary to increase understanding of ecological values beyond the science community. We show how the Ecosystem Principles Approach, a method that explains the importance of ocean processes via easily understandable ecological principles, might overcome this challenge for deep-sea ecosystem services. Scientists were asked to help develop a list of clear and concise ecosystem principles for the functioning of submarine canyons through a Delphi process to facilitate future transfers of ecological knowledge. These ecosystem principles describe ecosystem processes, link such processes to ecosystem services, and provide spatial and temporal information on the connectivity between deep and shallow waters. They also elucidate unique characteristics of submarine canyons. Our Ecosystem Principles Approach was successful in integrating ecological information into the ecosystem services assessment process. It therefore has a high potential to be the next step towards a wider implementation of ecological values in marine planning. We believe that successful communication of ecological knowledge is the key to a wider public support for ocean conservation, and that this endeavour has to be driven by scientists in their own interest as major deep-sea stakeholders.

Emotional Communication in Finger Braille

2010-01-01

Full Text Available We describe analyses of the features of emotions (neutral, joy, sadness, and anger expressed by Finger Braille interpreters and subsequently examine the effectiveness of emotional expression and emotional communication between people unskilled in Finger Braille. The goal is to develop a Finger Braille system to teach emotional expression and a system to recognize emotion. The results indicate the following features of emotional expression by interpreters. The durations of the code of joy were significantly shorter than the durations of the other emotions, the durations of the code of sadness were significantly longer, and the finger loads of anger were significantly larger. The features of emotional expression by unskilled subjects were very similar to those of the interpreters, and the coincidence ratio of emotional communication was 75.1%. Therefore, it was confirmed that people unskilled in Finger Braille can express and communicate emotions using this communication medium.

Hand use and gestural communication in chimpanzees (Pan troglodytes).

Science.gov (United States)

Hopkins, W D; Leavens, D A

1998-03-01

Hand use in gestural communication was examined in 115 captive chimpanzees (Pan troglodytes). Hand use was measured in subjects while they gestured to food placed out of their reach. The distribution of hand use was examined in relation to sex, age, rearing history, gesture type, and whether the subjects vocalized while gesturing. Overall, significantly more chimpanzees, especially females and adults, gestured with their right than with their left hand. Foods begs were more lateralized to the right hand than pointing, and a greater prevalence of right-hand gesturing was found in subjects who simultaneously vocalized than those who did not. Taken together, these data suggest that referential, intentional communicative behaviors, in the form of gestures, are lateralized to the left hemisphere in chimpanzees.

Work and Inter-subjectivity: a theoretical reflection on its dialectics in the field of health and nursing.

This theoretical reflection intends to show the inter-subjective relationship that takes place in health and nursing practices under the following theoretical perspectives: Institutional Analysis, Psychodynamics of Labor and the Theory of Communicative Action, with an emphasis on the latter. Linking these concepts to the Marxist approach to work in the field of health emerges from recognizing the need for its continuous reconstruction-in this case, with a view to understand the interaction and communication intrinsic to work in action. The theory of Communicative Action seeks to consider these two inextricable dimensions: work as productive action and as interaction. The first corresponds to instrumental action based on technical rules with a production-guided rationale. The second refers to the interaction that takes place as communicative action and seeks understanding among subjects. We assume that adopting this theoretical perspective in the analysis of health and nursing practices opens new possibilities for clarifying its social and historical process and inter-subjective connections.

Editorial. Dialogue, Communication and Collaboration: Aspects of Philosophy and Communication

Directory of Open Access Journals (Sweden)

Jovilė Barevičiūtė

2016-03-01

Full Text Available Acting as a usual means of everyday communication and collaboration, dialogue is also a fundamental mode of human presence in the world. It is innate and, therefore, feels organic to people. Nothing but a dialogue determines and defines the inborn human potential of reflexivity, empathy and communitivity. Naturally, it is hardly surprising that as a phenomenon, a dialogue constantly fell within the purview of most prominent European thinkers and throughout different historical epochs, in the spaces of philosophy and communication, it unfolded in a diverse and multidimensional manner. Ancient Greek philosopher Plato wrote in the form of dialogue, this way opening the possibility to a reader to learn about the world and the order of things as well as defining a certain relationship between the perceiving subject and the perceivable object. In the early Middle Ages, writings of Saint Augustine encouraged people to immerse into themselves and start a conversation with God, which established a certain living relationship between spaces empirical and transcendental. Much later, towards the end of the 19th and the beginning of the 20th century, German phenomenologist Edmund Husserl, who developed the theory of the intentionality of the consciousness, perceived that no living relationship between people is feasible without intersubjectivity. In this case, the communication is conditioned on the focus of at least two subjects on a certain object. This object, in particular, ensures the potential of the meaning, content and the purpose of communication. Another German author Martin Buber treated the dialogue as a phenomenon, in which an individual establishes a personal relationship with the Christian God, and this gives rise to a certain immediacy: a confrontation with the Ruler of the Kingdom of Heaven gives meaning to all the other interpersonal relationships. These are but few different philosophical interpretations of dialogue as a phenomenon. The

Electronic Word-of-Mouth Communication and Consumer Behaviour

The rapid adoption of social media, along with the easy access to peer information and interactions, has resulted in massive online word-of-mouth communication. These interactions among consumers have an increasing power over the success or failure of companies and brands. Drawing upon word-of-mouth...... communication and consumer behaviour theories, this paper investigates the use of word-of-mouth communication through social media among a group of Danish consumers. The findings suggest that electronic word-of-mouth communication among friends and peers affect consumer behaviour. Additionally, peer...... communication is perceived as more objective and therefore found more reliable than companies’ brand communication. Furthermore, negative word-of-mouth is perceived as more trustworthy compared to positive messages, which are often believed to be too subjective. The research findings emphasise the importance...

Bones, Michelle; Nunlee, Martin

2018-05-28

Pharmacy personnel often answer telephones to respond to pharmacy customers (subjects) who received messages from automated systems. This research examines the communication process in terms of how users interact and engage with pharmacies after receiving automated messages. No study has directly addressed automated telephone calls and subjects' interactions. The purpose of this study is to test the interpersonal communication (IC) process of uncertainty in subjects in receipt of automated telephone calls ATCs from pharmacies. Subjects completed a survey of validated scales for Satisfaction (S); Relevance (R); Quality (Q); Need for Cognitive Closure (NFC). Relationships between S, R, Q, NFC, and subject preference to ATCs were analyzed to determine whether subjects contacting pharmacies display information seeking behavior. Results demonstrated that seeking information occurs if subjects: are dissatisfied with the content of the ATC; perceive that the Q of ATC is high and like receiving the ATC, or have a high NFC and do not like receiving ATCs. Other interactions presented complexities amongst uncertainty and tolerance of NFC within the IC process.

Relatively little attention has been devoted to the role of communication between physicians as a mechanism for individual and organisational learning about diagnostic delays. This study's objective was to elicit physicians' perceptions about and experiences with communication among physicians regarding diagnostic delays in cancer. Qualitative analysis based on seven focus groups. Fifty-one physicians affiliated with three New York-based academic medical centres participated, with six to nine subjects per group. We used content analysis to identify commonalities among primary care physicians and specialists (ie, medical and surgical oncologists). Perceptions and experiences with physician-to-physician communication about delays in cancer diagnosis. Our analysis identified five major themes: openness to communication, benefits of communication, fears about giving and receiving feedback, infrastructure barriers to communication and overcoming barriers to communication. Subjects valued communication about cancer diagnostic delays, but they had many concerns and fears about providing and receiving feedback in practice. Subjects expressed reluctance to communicate if there was insufficient information to attribute responsibility, if it would have no direct benefit or if it would jeopardise their existing relationships. They supported sensitive approaches to conveying information, as they feared eliciting or being subject to feelings of incompetence or shame. Subjects also cited organisational barriers. They offered suggestions that might facilitate communication about delays. Addressing the barriers to communication among physicians about diagnostic delays is needed to promote a culture of learning across specialties and institutions. Supporting open and honest discussions about diagnostic delays may help build safer health systems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Mirza, D M; Hashim, M J

2010-08-01

Communications skills curricula and pedagogy for medical students are often exported to non-English speaking settings. It is assumed that after learning communication skills in English, doctors will be able to communicate effectively with patients in their own language. We distributed a questionnaire to third year Emirati students at a medical school within the United Arab Emirates. We assessed their confidence in interviewing patients in Arabic after communication skills training in English. Of the 49 students in the sample, 36 subjects (73.5%) completed and returned the questionnaire. Nearly three-quarters (72.2%) of students said they felt confident in taking a history in English, while 27.8% of students expressed confidence in taking a history in Arabic. Half of students anticipated that after their training they would be communicating with their patients primarily in Arabic, and only 8.3% anticipated they would be communicating in English. Communication skills training purely in English can leave Arab medical students ill equipped to communicate with patients in their own communities and tongue.

Our experimental evidence lends support to the view that communication affects subjects in a way...... that is compatible with the level-k model, indicating that people lie in order to fool other players that they believe do less thinking. Moreover, the results indicate that the predictive power of the level-k model does crucially depend on the possibility for high level players to form homogenous beliefs about...

Pulmonary capillary wedge pressure, as inferred from lung areas in gated blood-pool scintigrams: concise communication

Urbina, A.; Okada, R.D.; Palacios, I.; Osbakken, M.; Strauss, H.W.

1981-01-01

To determine whether the apex-to-base distribution of pulmonary blood volume, as obtained from gated cardiac blood-pool scans, could be used as a noninvasive method to estimate mean pulmonary capillary wedge pressure (PCWP), gated blood-pool scans were analyzed in 77 patients who also had PCWP measurements at cardiac catheterization. Ten of these patients had gated cardiac blood-pool scans and PCWP measurements both at rest and during exercise. The apex-to-base distribution of pulmonary blood volume was determined from the end-systolic frame of the left anterior oblique view by placing equal-sized regions of interest over the apex and base of the right lung. The ratio of apex counts over base counts (A/B ratio) was considered abnormal if greater than unity. The mean A/B ratio was 1.15 +/- 0.27 (1 s.d.) for the 32 studies associated with an abnormal mean PCWP (greater than 12 mm Hg). The mean A/B ratio was 0.85 +/- 0.23 for the 55 studies associated with a normal mean PCWP (p less than 0.01 comparing normal group with abnormal). The sensitivity of the A/B ratio for a mean PCWP greater than 12 mm Hg was 81%R (26/32). The specificity of the A/B ratio for a mean PCWP greater than or equal to 12 mm Hg was 89% (49/55). Thus, noninvasive determination of the pulmonary apex-to-base ratio from gated cardiac blood-pool scans appears to differentiate subjects with normal and abnormal mean pulmonary capillary wedge pressures

Allergic rhinitis (AR) is a chronic disorder with a high prevalence in the general population. The symptoms of AR can impair the cognitive capabilities of the affected people. The study of communication skills and AR interaction has not been adequately discussed. We aimed to analyze Social Communication Skills of university students with AR. Fifty patients suffering from AR and 50 healthy subjects were studied. All participants completed two questionnaires [Social Communication Skills Rating Scale (SCSRS) and Communication Questionnaire] for the assessment of social communication skills. Total scores of both SCSRS and Communication Questionnaire were higher in participants with AR than controls. When the questions of SCSRS were compared between the groups one by one, significant difference was observed between the groups for questions numbered 1-9 and 11, 12 (p Communication Questionnaire (p communication skills of the patients with AR.

This process can be voluntarily controlled, making it a candidate for communication from human user to machine in a brain-computer interface (BCI) system. In this study we investigated whether subjective accenting is a feasible paradigm for BCI and how its time-structured nature can be exploited for optimal decoding from non-invasive EEG data. Ten subjects perceived and imagined different metric patterns (two-, three- and four-beat) superimposed on a steady metronome. With an offline classification paradigm, we classified imagined accented from non-accented beats on a single trial (0.5 s) level with an average accuracy of 60.4% over all subjects. We show that decoding of imagined accents is also possible with a classifier trained on perception data. Cyclic patterns of accents and non-accents were successfully decoded with a sequence classification algorithm. Classification performances were compared by means of bit rate. Performance in the best scenario translates into an average bit rate of 4.4 bits min-1 over subjects, which makes subjective accenting a promising paradigm for an online auditory BCI.

Full Text Available The article is devoted to the study of the problems of didactic communication in the training of engineering personnel for the aerospace industry and to the study of the problems of the communication of subjects concerning the training and education of highly qualified engineering personnel for the aerospace industry. In the training of engineering personnel for the aerospace industry the integrated model of didactic communication involves the identification and description of its various components, typical modes of interaction (modes that reflect different aspects of the person's understanding of the world around him and himself in the process of different types of education and upbringing. Didactic communication in the process of training engineering personnel for the aerospace industry is a multi-level, multi-stage and multi-component phenomenon. The modes, possibilities and limitations of this communication are related to the level and direction of personal, interpersonal and professional development of interaction subjects. The productivity of preparing engineering personnel for the aerospace industry is related to the choice of a model of didactic communication, which is addressed in different ways to the development of cognitive, value-semantic and meta-cognitive structures that form one or another type of education and upbringing.

Environmental Warning System Based on the DPSIR Model: A Practical and Concise Method for Environmental Assessment

Directory of Open Access Journals (Sweden)

Wenqi Wang

2018-05-01

Full Text Available Though we are in urgent need of environmental warnings to slow environmental deterioration, currently, there is no internationally concise method for environmental warnings. In addition, the existing approaches do not combine the three aspects of ecology, resources, and environment. At the same time, the three elements of the environment (air, water, and soil are separated in most environmental warning systems. Thus, the method this paper gives is an innovative attempt and aims to make environmental assessment more practical. This paper establishes the index system of an environmental early warning based on the Driving–Pressure–State–Influence–Response (DPSIR model. The Analytic Hierarchy Process (AHP method was used to determine the weights. Next, single and integrated index methods further assess the environmental warning state, in which the weighted summation method is used to summarize the data and results. The case of Tianjin is used to confirm the applicability of this method. In conclusion, the method in this paper is more well-behaved and, therefore, more suitable to assist cities in their environmental assessment.

From the comparison of the various aspects of advertising and personal selling, it can be seen that personal selling is a more effective and powerful communication tool than advertising, but advertising is more time and cost efficient than personal selling. Thus advertising and personal selling are tools at the disposal of a marketer and subjects to a firm’s overall objectives.

How can we identify and communicate the ecological value of deep-sea ecosystem services?

Directory of Open Access Journals (Sweden)

Niels Jobstvogt

Full Text Available Submarine canyons are considered biodiversity hotspots which have been identified for their important roles in connecting the deep sea with shallower waters. To date, a huge gap exists between the high importance that scientists associate with deep-sea ecosystem services and the communication of this knowledge to decision makers and to the wider public, who remain largely ignorant of the importance of these services. The connectivity and complexity of marine ecosystems makes knowledge transfer very challenging, and new communication tools are necessary to increase understanding of ecological values beyond the science community. We show how the Ecosystem Principles Approach, a method that explains the importance of ocean processes via easily understandable ecological principles, might overcome this challenge for deep-sea ecosystem services. Scientists were asked to help develop a list of clear and concise ecosystem principles for the functioning of submarine canyons through a Delphi process to facilitate future transfers of ecological knowledge. These ecosystem principles describe ecosystem processes, link such processes to ecosystem services, and provide spatial and temporal information on the connectivity between deep and shallow waters. They also elucidate unique characteristics of submarine canyons. Our Ecosystem Principles Approach was successful in integrating ecological information into the ecosystem services assessment process. It therefore has a high potential to be the next step towards a wider implementation of ecological values in marine planning. We believe that successful communication of ecological knowledge is the key to a wider public support for ocean conservation, and that this endeavour has to be driven by scientists in their own interest as major deep-sea stakeholders.

Holyfield, Christine; Caron, Jessica Gosnell; Drager, Kathryn; Light, Janice

2018-03-05

Visual scene displays (VSDs) and just-in-time programming supports are augmentative and alternative communication (AAC) technology features with theoretical benefits for beginning communicators of all ages. The goal of the current study was to evaluate the effects of a communication application (app) on mobile technology that supported the just-in-time programming of VSDs on the communication of preadolescents and adolescents who were beginning communicators. A single-subject multiple-baseline across participant design was employed to evaluate the effect of the AAC app with VSDs programmed just-in-time by the researcher on the communication turns expressed by five preadolescents and adolescents (9-18 years old) who were beginning communicators. All five participants demonstrated marked increases in the frequency of their communication turns after the onset intervention. Just-in-time programming support and VSDs are two features that may positively impact communication for beginning communicators in preadolescence and adolescence. Apps with these features allow partners to quickly and easily capture photos of meaningful and motivating events and provide them immediately as VSDs with relevant vocabulary to support communication in response to beginning communicators' interests.

This work aims to analyse the specific contribution of social abilities (here considered as the capacity for attributing knowledge to others) in a particular communicative context. 74 normally developing children (aged 3;4 to 5;9, M = 4.6) were given two Theory of Mind (ToM) tasks, which are considered to assess increasing complexity levels of epistemic state attribution: Attribution of knowledge-ignorance (Pillow, 1989; adapted by Welch-Ross, 1997) and Understanding of False-belief (Baron Cohen, Leslie & Frith, 1985). Subjects were paired according to their age and level of performance in ToM tasks. These dyads participated in a referential communication task specially designed for this research. The resulting communicative interchanges were analysed using a three-level category system (pragmatic functions, descriptive accuracy, and ambiguity of messages). The results showed significant differences among subjects with different levels of social comprehension regarding the type of communicative resources used by them in every category level. In particular, understanding of false belief seems to be the most powerful predictor of changes in the children's development of communicative competence.

Full Text Available Educational managers transport information, thoughts and attitudes through a system of verbal and nonverbal language. What differs across diverse personalities is the level of communication effectiveness which ascertains the success in the flow of messages not only at the organizational level but also in the classroom where learning takes place. This study, which aimed to disclose correlations between language constructs and communication effectiveness, puts the light to the randomly selected educational management students of a state university in Cagayan Valley. Using a language test and a questionnaire, it was revealed that the level of language proficiency of the respondents as to correct usage, presentation and writing is very satisfactory, and as to subject-verb agreement, vocabulary, reading comprehension, listening comprehension, and action research, satisfactory; while their level of communication effectiveness along using non-verbal language, transmitting messages and receiving messages is high. At 0.05 level analysis, significant correlations exist between communication effectiveness (along using nonverbal language and receiving messages and language proficiency along reading. These findings provided insights in enhancing communication in classroom management, organizational management as well as in communication management instruction..

Objective: Knowledge, information and communication, within oncology, are a core clinical strength for the out-come of the disease and inadequate communication, can cause distress for the patient and their families. Design: A senior doctor conducted this study by filling in the performa after interviewing the subject of the study. Place and duration of study: This study was done in Oncology Department of Service Hospital, Lahore and was completed in four months. Subjects and Method: One hundred cancer patients were interviewed regarding their knowledge about their disease, its causes, prognosis, and information supplied by the health-care providers. They were also asked about their satisfaction regarding this information, deficiencies and pitfalls in this information, need for more information, which should supply the information from among the hospital team or their relative, attitude of the family and their communication regarding the disease. Results: Study revealed that the knowledge about the disease and its causes was present in 53% and 7% respectively. The patients (59%) wanted more information. Majority perceived that the information was not adequate and needed more information and 68% thought that more information would reduce their anxiety. The attitude of family was found encouraging in 87% of patients and 42% were communicating with other family members regarding their diseases. Conclusion: Knowledge about the disease and its cause should be increasingly supplied by the doctors, as it will reduce the anxiety and have a good effect on health. Communication among the family members needs to be improved. (author)

Communication as a Strategic Activity (Invited)

Science.gov (United States)

Fischhoff, B.

2010-12-01

Effective communication requires preparation. The first step is explicit analysis of the decisions faced by audience members, in order to identify the facts essential to their choices. The second step is assessing their current beliefs, in order to identify the gaps in their understanding, as well as their natural ways of thinking. The third step is drafting communications potentially capable of closing those gaps, taking advantage of the relevant behavioral science. The fourth step is empirically evaluating those communications, refining them as necessary. The final step is communicating through trusted channels, capable of getting the message out and receiving needed feedback. Executing these steps requires a team involving subject matter experts (for ensuring that the science is right), decision analysts (for identifying the decision-critical facts), behavioral scientists (for designing and evaluating messages), and communication specialists (for creating credible channels). Larger organizations should be able to assemble those teams and anticipate their communication needs. However, even small organizations, individuals, or large organizations that have been caught flat-footed can benefit from quickly assembling informal teams, before communicating in ways that might undermine their credibility. The work is not expensive, but does require viewing communication as a strategic activity, rather than an afterthought. The talk will illustrate the science base, with a few core research results; note the risks of miscommunication, with a few bad examples; and suggest the opportunities for communication leadership, focusing on the US Food and Drug Administration.

2013-04-01

Full Text Available The aim of the paper is to characterize the communicative peculiarities of the interpretative-deliberative style in pedagogical discourse. The object of the study is interpretative-deliberative style viewed as one of the communication forms in pedagogical discourse; the subject of the analysis is the stratagem and tactics characteristics of the interpretative-deliberative communicative style. Descriptive and analytical as well as stylistic and discourse analysis methods are employed. The author reveals the most prevalent strategies–explanatory, interpretative and deliberative–employed in communicative interaction in situations of educative persuasion. The communicative characteristics of the analyzed style are: a rational type of the communicative action, a trust-based tone and the emotional involvement of the communication participants. The results can be used for clarifying specifics of speech behavior in educative communication as well as for comparing styles of educative communication in different enthnocultural traditions.

Borg, Erik; Bergkvist, Christina; Olsson, Inga-Stina; Wikström, Carina; Borg, Birgitta

2008-11-01

A conceptual framework for human communication, based on traditional biological ecology, is further developed. The difference between communication at the message and behavioural levels is emphasized. Empirical data are presented from various studies, showing that degree of satisfaction with communication is correlated with how close the outcome is to the memory of function prior to hearing impairment. We found no indication that hearing-impaired subjects overestimated their previous hearing or the hearing of normal-hearing people. Satisfaction was also correlated with the outcome and degree of fulfillment of expectations. It did not correlate with improvement of function. The concept of balance was presented and tested using a semi-quantitative approach. Several projects were presented in which the framework was applied: the hearing impaired as counsellor, choosing sides in unilateral deafness, a monitoring device for the deafblind, interaction between Swedish as a second language and hearing impairment, language development in hearing impaired children. By regarding hearing as a component of a communicative system, the perspective of audiological analysis and rehabilitation is broadened.

2017-01-01

This paper presents the results of a large study of 1340 articles published by two major newspapers in six European countries (Belgium, Italy, Norway, Slovenia, Spain and Russia) in the first 2 months after the Fukushima Daiichi nuclear disaster. The focus of the analysis is on the application and overall impact of protective actions, both during the emergency phase and later, how the newspapers describe those actions, which differences were apparent between countries and what recommendations can be extracted in order to improve general communication about these issues. A clear lesson is that, even under uncertainty and recognising limitations, responsible authorities need to provide transparent, clear and understandable information to the public and the mass media right from the beginning of the early phase of any nuclear emergency. Clear, concise messages should be given. Mass media could play a key role in reassuring the public if the countermeasures are clearly explained. (authors)

Some internal medicine residency program directors have expressed concerns that their third-year residents may have been subjected to inappropriate communication during the 2016 fellowship recruitment season. The authors sought to study applicants' interpersonal communication experiences with fellowship programs. Many respondents indicated that they had been asked questions that would constitute violations of the National Residency Matching Program (NRMP) Communications Code of Conduct agreement, including how they plan to rank specific programs. Moreover, female respondents were more likely to have been asked questions during interview experiences about other programs to which they applied, and about their family plans. Post-interview communication policies were not made clear to most applicants. These results suggest ongoing challenges for the internal medicine community to improve communication with applicants and uniform compliance with the NRMP communications code of conduct during the fellowship recruitment process.

Giles, Howard; Khajavy, Gholam Hassan; Choi, Charles W

2012-12-01

Guided by the communicative predicative model of aging, American and Iranian young adults' perceptions of communication with their peers, middle-aged and elderly adults were examined; subjective boundaries for these age categories were also explored. As age of target increased, so did attributions of benevolence, norms of politeness and deference, and communicative respect and avoidance; conversely, attributions of personal vitality and communication satisfaction decreased linearly. Path analysis was also adopted to examine the simultaneous relationships between the variables under study, and ultimately with cultural caveats largely supported, a hypothesized model was derived. The data were discussed in terms of their yielding refinements and elaborations to the communicative predicament and enhancement models of aging.

The field of Strategic Communication involves a focused effort to identify, develop, and present multiple types of communication media on a given subject. A Strategic Communication program recognizes the limitations of the most common communication models (primarily “one size fits all” and “presenting everything and letting the audience decide what is important”) and specifically focuses on building a communication framework that is composed of three interlinked pillars: (1) Message – Identifying the right content for a given audience and a vehicle, (2) Audience – Identify the right target group for a given message and vehicle, (3) Vehicle – Identifying the right types of media for a given message and audience. In addition to serving as an organizational framework, the physical structure of a Strategic Communication plan also can serve as a way to show an audience where they, the message, and vehicle fit into the larger picture (i.e., “you are here”). This presentation explores the tenets of Strategic Communication and its use in natural resources management as it relates to advancing restoration activities in the Greater Everglades. This presentation is aimed at restoration practitioners and decision makers. This presentation provides an introduction to the field of strategic communication and presents a generalizable framework for use in the natural sciences. The presentation also gives an example of a communication implementation matrix,

A Concise Method for Storing and Communicating the Data Covariance Matrix

Energy Technology Data Exchange (ETDEWEB)

Larson, Nancy M [ORNL

2008-10-01

The covariance matrix associated with experimental cross section or transmission data consists of several components. Statistical uncertainties on the measured quantity (counts) provide a diagonal contribution. Off-diagonal components arise from uncertainties on the parameters (such as normalization or background) that figure into the data reduction process; these are denoted systematic or common uncertainties, since they affect all data points. The full off-diagonal data covariance matrix (DCM) can be extremely large, since the size is the square of the number of data points. Fortunately, it is not necessary to explicitly calculate, store, or invert the DCM. Likewise, it is not necessary to explicitly calculate, store, or use the inverse of the DCM. Instead, it is more efficient to accomplish the same results using only the various component matrices that appear in the definition of the DCM. Those component matrices are either diagonal or small (the number of data points times the number of data-reduction parameters); hence, this implicit data covariance method requires far less array storage and far fewer computations while producing more accurate results.

Gastric visualization and image quality in radionuclide bone scanning: concise communication

International Nuclear Information System (INIS)

Wilson, M.A.; Pollack, M.J.

1981-01-01

In a 12-mo study period, there were 14 days identified when the stomach was visualized in routine bone imaging. On these days, 44% of the 110 patients imaged demonstrated this effect. Only the quality control, binding efficiency, and scan quality differed (p less than 0.005) when the study population was compared with a reference population of 162 patients. However, on the days when this effect was noted, there was a significant (p less than 0.001) linear correlation between the presence and degree of gastric visualization and the radiopharmaceutical incubation and quality control parameters. The study suggests a sporadic phenomenon that appears to result from partial oxidation of the agent during incubation, producing (a) different species of labeled diphosphonate that display altered affinity for bone (scan quality) and (b) free pertechnetate

An appendicular skeletal response to sodium fluoride (NaF) was detected by total skeletal scintigrams. Twelve postmenopausal osteoporotic women were treated with NaF (88 mg/day) and calcium (1500 mg/day). Total skeletal scintigrams were obtained before and during treatment. Within 4 to 21 mo (mean: 8.3), all 12 patients showed new areas of increased uptake corresponding to metaphyseal regions and short bones of the appendicular skeleton. Nine patients showed an increase in serum alkaline phosphatase activity, which was attributed to an increase in the skeletal isoenzyme. Seven of 12 patients developed bone pain in one or more of the regions of increased uptake. This study establishes that the skeletal scintigram is a sensitive index of the peripheral skeletal response to NaF

The need for rapid, definitive identification of coronary thrombosis has been intensified by the advent of thrombolytic therapy and by interest in the role of thrombosis in the etiology of coronary artery disease. To determine whether platelet thrombi can be detected noninvasively with 111 In platelets, a method was developed in which /sup 99m/Tc-tagged red blood cells were used to correct for activity within the blood attributable to platelets circulating but not associated with thrombus. In 18 dogs coronary thrombi were induced closed-chest with a copper coil introduced into the coronary artery. 111 In platelets and /sup 99m/Tc RBCs were administered either before or 1 hr after induction of thrombus, and serial scintigrams obtained. Coronary thrombus was identified readily in the processed scintigrams. In six dogs, thrombolysis was achieved with intracoronary streptokinase. In each case serial scintigraphy demonstrated resolution of the clot. The dual radiotracer technique should permit serial noninvasive delineation of the temporal relationship between platelet deposition and coronary heart disease in patients, and should facilitate the evaluation of interventions designed to prevent platelet aggregation or to lyse existing thrombi

Blood clearance rates of technetium-99m albumin preparations: concise communication

Technetium-labeled human serum albumin (HSA) is extensively used as a cardiac imaging agent. An evaluation of the blood-clearance rates of electrolytically reduced HSA (EHSA) and four stannous-reduced HSA (SnHSA) preparations was conducted in dogs, and was compared with that of radioiodinated HSA (IHSA). The EHSA was found to have a clearance rate only about 1.5 times that of IHSA, whereas the SnHSA agents were cleared at two to five times the rate of IHSA. Thus, EHSA has definite advantages over SnHSA preparations for the purposes of blood-volume determinations required in quantitative cardiac studies and for the reduction of extravascular background in the accurate delineation of cardiac boundaries

Although radioiodinated cholesterols furnished the first noninvasive imaging of the adrenal glands, it would be desirable to decrease the time for imaging and decrease the radiation dose. The relative tissue distributions of two radiolabeled enzyme inhibitors [ 3 H] metyrapol and 1-125-SKF-12185 were studied in dogs and man. Their percentage uptakes and target-to-nontarget ratios were similar. The adrenals of three dogs were imaged sharply at 2 hr after injection with 4-6 mCi of I-131-SKF-12185, confirmed by subsequent imaging with 1 mCi of I-131-6-beta-19-nor cholesterol at 5 days after injection. The use of 1 mCi of I-123-SKF will pemit imaging of the adrenals in 1-2 hr and will decrease the radiation dose in the human to 0.76 rads to the adrenal, 0.18 rads to the ovaries and 1.7 rads to the liver

The authors describe their recently developed Computer-aided VIsual Communication (C-VIC) system, and report results of single-subject experimental designs probing its use with five chronic, severely impaired aphasic individuals. Studies replicate earlier results obtained with a non-computerized system, demonstrate patient competence with the computer implementation, extend the system's utility, and identify promising areas of application. Results of the single-subject experimental designs clarify patients' learning, generalization, and retention patterns, and highlight areas of performance difficulties. Future directions for the project are indicated.

Hantho, Arne; Jensen, Lena; Malterud, Kirsti

2002-12-01

To present our pursuits towards development of a simple model for clinical communication intended for application by the practitioner as a tool for enhancing mutual understanding. Inspired by theories about patient-centredness and interactive modes of understanding, and supported by the perspectives of the Danish philosopher Niels Thomassen, we reviewed audiotapes from our own consultations. Recognising four dimensions assumed to be essential for mutual understanding in the transcripts, we explored these dimensions further. We present a communication model consisting of the following dimensions: The Framework, within which the communication takes place; The Subject, about which the communication takes place; The Persons, between whom the communication takes place; and The Action, verbally and non-verbally, through which communication takes place. We describe these dimensions in detail. The nature of the dimensions indicates that there is an interrelationship between them, implying that the character of the communication may change if one of the factors is changed. Analysis of an ongoing or recent consultation completed in accordance with these four dimensions allows the doctor to refocus the communication, thus leading to a more extensive mutual understanding and perhaps enhanced freedom of action.

1983-01-01

Information theoretic analysis and subjective paired-comparison and task ranking techniques were employed in order to scale the workload of 20 communications-related tasks frequently performed by the captain and first officer of transport category aircraft. Tasks were drawn from taped conversations between aircraft and air traffic controllers (ATC). Twenty crewmembers performed subjective message comparisons and task rankings on the basis of workload. Information theoretic results indicated a broad range of task difficulty levels, and substantial differences between captain and first officer workload levels. Preliminary subjective data tended to corroborate these results. A hybrid scale reflecting the results of both the analytical and the subjective techniques is currently being developed. The findings will be used to select representative sets of communications for use in high fidelity simulation.

Good communication skills are essential for an optimal doctor-patient relationship, and also contribute to improved health outcomes. Although the need for training in communication skills is stated as a requirement in the 1997 Graduate Medical Education Regulations of the Medical Council of India, formal training in these skills has been fragmentary and non-uniform in most Indian curricula. The Vision 2015 document of the Medical Council of India reaffirms the need to include training in communication skills in the MBBS curriculum. Training in communication skills needs approaches which are different from that of teaching other clinical subjects. It is also a challenge to ensure that students not only imbibe the nuances of communication and interpersonal skills, but adhere to them throughout their careers. This article addresses the possible ways of standardizing teaching and assessment of communication skills and integrating them into the existing curriculum.

SOCIOMETRIC INVESTIGATION OF PONY-MANIA CONNECTION IN COMMUNICATION WITH COGNITIVE STYLES OF MEMBERS OF THE GROUP

Full Text Available The article is devoted to the analysis of mutual understanding in communication with the cognitive styles of the members of the group and revealing the connection between the productivity of people's understanding of each other in communication and the degree of their psychologic differentiation. Our study is that subjects - schoolchildren in the mass do not differentiate such aspects in a person as "ability to understand, to be understood" and "sympathy, pleasantness". Thus, due to the "halo effect", people pleasant and sympathetic in communication stand out in the implicit theories of our subjects and positive traits by the criterion of "understanding." The above experiment allows further analysis of the influence of cognitive style on understanding in communication. Sufficiently differentiate the subjects under investigation in the sphere of interpersonal relations and distinguish the criterion of "understanding" from the other criteria used in sociometry.

Samokhvalova, Anna G.

2016-09-01

Full Text Available Contemporary psychological and pedagogical studies pay special attention to the socialization of physically impaired children, inclusive education and methods of providing such children with a safe environment to assist in their development. However, difficulties in interpersonal communication experienced by children with health impairments have remained beyond the research scope. The authors conducted a comparative analysis of communication difficulties in typically developed teenagers aged 12-13 years (n = 100 and the problems faced by their peers with visual (n = 30, auditory (n = 30, speech (n = 25 and motor (n = 15 impairments. Actual communication difficulties in teenagers were studied in two ways: the subjective component of impaired communication was registered through a content analysis of a sentence completion test and the objective manifestations of impaired communication were identified through expert evaluation of children’s communicative behavior (educators and psychologists who had been in close contact with the teenagers acted as experts. First, the authors identified typical standard communication problems that were characteristic of teenagers aged 12-13 years, that is, problems with aggression, tolerance, the ability to admit wrongdoing and make concessions, empathy, self-control, self-analysis and self-expression in communication. Second, typical communication difficulties characteristic of physically impaired children were revealed: failure to understand meaning; feelings of awkwardness and shame of oneself; expectations of a negative attitude toward oneself; gelotophobia; and manifestations of despotism, petulance and egotism as defensive reactions in situations of impaired communication. Third, the authors described specific communication difficulties in teenagers with auditory, visual, speech and motor impairments.

The social gradient in doctor-patient communication

2012-03-01

Full Text Available Abstract Objective In recent years, the importance of social differences in the physician-patient relationship has frequently been the subject of research. A 2002 review synthesised the evidence on this topic. Considering the increasing importance of social inequalities in health care, an actualization of this review seemed appropriate. Methods A systematic search of literature published between 1965 and 2011 on the social gradient in doctor-patient communication. In this review social class was determined by patient's income, education or occupation. Results Twenty original research papers and meta-analyses were included. Social differences in doctor-patient communication were described according to the following classification: verbal behaviour including instrumental and affective behaviour, non-verbal behaviour and patient-centred behaviour. Conclusion This review indicates that the literature on the social gradient in doctor-patient communication that was published in the last decade, addresses new issues and themes. Firstly, most of the found studies emphasize the importance of the reciprocity of communication. Secondly, there seems to be a growing interest in patient's perception of doctor-patient communication. Practice implications By increasing the doctors' awareness of the communicative differences and by empowering patients to express concerns and preferences, a more effective communication could be established.

Visual Communication in Web Design - Analyzing Visual Communication in Web Design

Science.gov (United States)

Thorlacius, Lisbeth

Web sites are rapidly becoming the preferred media choice for information search, company presentation, shopping, entertainment, education, and social contacts. And along with the various forms of communication that the Web offers the aesthetic aspects have begun to play an increasingly important role. However, studies in the design and the relevance of focusing on the aesthetic aspects in planning and using Web sites have only to a smaller degree been subject of theoretical reflection. For example, Miller (2000), Thorlacius (2001, 2002, 2005), Engholm (2002, 2003), and Beaird (2007) have been contributing to set a beginning agenda that address the aesthetic aspects. On the other hand, there is a considerable amount of literature addressing the theoretical and methodological aspects focusing on the technical and functional aspects. In this context it is the aim of this article to introduce a model for analysis of visual communication on websites.

People with bipolar disorder are at high risk of suicide, but no clinically useful scale has been validated in this population. The aim of this study was to evaluate the psychometric properties in bipolar disorder of the 7- and 12-item versions of the Concise Health Risk Tracking Self-Report (CHRT-SR), a scale measuring suicidal ideation, suicidal behavior, and associated symptoms. The CHRT was administered to 283 symptomatic outpatients with bipolar I or II disorder who were randomized to receive lithium plus optimized personalized treatment (OPT), or OPT without lithium in a six month longitudinal comparative effectiveness trial. Participants were assessed using structured diagnostic interviews, clinician-rated assessments, and self-report questionnaires. The internal consistency (Cronbach α) was 0.80 for the 7-item CHRT-SR and 0.90 for the 12-item CHRT-SR with a consistent factor structure, and three independent factors (current suicidal thoughts and plans, hopelessness, and perceived lack of social support) for the 7-item version. CHRT-SR scores are correlated with measures of depression, functioning, and quality of life, but not with mania scores. The 7- and 12-item CHRT-SR both had excellent psychometric properties in a sample of symptomatic subjects with bipolar disorder. The scale is highly correlated with depression, functioning, and quality of life, but not with mania. Future research is needed to determine whether the CHRT-SR will be able to predict suicide attempts in clinical practice. Published by Elsevier Ltd.

2012-01-01

Document available in abstract form only. Full text of publication follows: Andra is responsible for proposing and implementing industrial management solutions for France's radioactive waste. Andra's goal is to ensure that everyone has the opportunity to make up his or her own mind on a subject that generates such heated debate within our society. This duty of communication is enshrined in law and is an integral part of Andra's activities, in the same way as research, industry and risk management. Because the subject of radioactive waste is a complex one and concerns such a variety of audiences, Andra adapts its communication policy so that it is accessible to all, according to individual needs and levels of interest. For the 'non-specialists' (general public, young people, etc.) Andra proposes a system built around education and awareness-raising. Its aim is to make the subject of radioactive waste accessible to and comprehensible to as many as possible. Its educational communication approach is built on 3 pillars: first and foremost information, the keystone of any system of communication, then explanation and finally sharing with the legitimate stakeholders in this pedagogical approach. Providing dependable information Andra offers information that is appropriate to the level of knowledge of its audiences and uses all communication media

The unprecedented popularity of online communication has raised interests and concerns among the public as well as in scholarly circles. Online communications have pushed people farther away from one another. This study is a further examination of the effects of online communications on well-being, in particular: Locus of control, Loneliness, Subjective well-being, and Preference for online social interaction. Chinese undergraduate students (N = 260; 84 men, 176 women; M age = 20.1 yr., SD = 1.2) were questioned about demographic information and use of social media as well as four previously validated questionnaires related to well-being. Most participants used QQ, a popular social networking program, as the major channel for online social interactions. Locus of control was positively related to Loneliness and Preference for online social interaction, but negatively related to Subjective well-being; Loneliness (positively) and Subjective well-being (negatively) were related to Preference for online social interaction; and Loneliness and Subjective well-being had a full mediating effect between the relationships of Locus of control and Preference for online social interaction. The findings of the study showed that more lonely, unhappy, and externally controlled students were more likely to be engaged in online social interaction. Improving students' locus of control, loneliness, and happiness may help reduce problematic Internet use.

Full Text Available : Individual learner differences play an integral role in second language acquisition and interested researchers and practitioners cannot get a full appreciation of second language learning if they ignore these significant variables. This study investigated how willingness to communicate (WTC, learner subjectivity, and anxiety in learning the L2 correlate with Iranian students’ English pragmatic knowledge. To this end, a total of 140 participants received instruction on request strategy types and their internal and external modification devices for seven weeks through consciousness-raising tasks. The data were obtained through WTC questionnaire, learner subjectivity questionnaire, foreign language classroom anxiety scale, and discourse completion test. The findings indicated that WTC and learner subjectivity correlated positively with the participants’ L2 pragmatic competence. However, no relationship was observed between the learners’ anxiety and their pragmatic achievement. The results suggest that some personal characteristics such as WTC and learner subjectivity are significant contributors to success in acquiring L2 pragmatic knowledge. چکیده: تفاوت های فردی زبان آموزان نقش غیر قابل انکاری در یادگیری زبان دوم ایفا میکنند و محققان علاقه مند نخواهند توانست به درک کامل و درستی از یادگیری زبان دوم برسند اگر چنین متغیرهای مهمی را نادیده بگیرند. این مطالعه به بررسی چگونگی ارتباط تمایل به برقراری ارتباط کلامی (WTC،  فردیت زبان آموز و اضطراب در یادگیری زبان دوم با دانش منظور شناسی زبان آموزان ایرانی می پردازد. برای این منظور، در مجموع 140 نفر در مورد انواع استراتژی های درخواست و ابزارهای �

Perspective: clinical communication education in the United Kingdom: some fresh insights.

Science.gov (United States)

Brown, Jo

2012-08-01

Clinical communication education is now part of the core curriculum of every medical school in the United Kingdom and the United States. It has emerged over 30 years because of various societal, political, and policy drivers and is supported by an impressive evidence base.For a variety of reasons, however, clinical communication has become separated from other parts of medical education and tends to be positioned in the early years of the curriculum, when students have limited experience of being in the clinical workplace and working with patients. The teachers of clinical communication, whether medical-school-based or clinically based, may not share learning goals for the subject and this may, therefore, provide a disintegrated learning experience for students.Clinical communication teachers need to inject fresh thinking into the teaching and learning of the subject to unite it with clinical practice in the authentic clinical workplace. Engaging with theories of workplace learning, which aim to overcome the theory/practice gap in vocational education, may be the way forward. The author suggests various ways that this might be achieved-for example, by situating clinical communication education throughout the whole undergraduate curriculum, by integrating the topic of clinical communication with other areas of medical education, by developing coteaching and curriculum design partnerships between medical school and clinical workplace, and by developing a greater range of postgraduate education that offers opportunities for professional development in clinical communication for qualified doctors that is complementary with what is taught in undergraduate education.

Selective pressures on the once and future contents of ethnic stereotypes: effects of the communicability of traits.

Schaller, Mark; Conway, Lucian Gideon; Tanchuk, Tracy L

2002-06-01

It is hypothesized that traits that are most likely to be the subject of social discourse (i.e., most communicable) are most likely to persist in ethnic stereotypes over time and that this effect is moderated by the extent to which an ethnic group is the subject of social discourse. Study 1 yielded communicability ratings of 76 traits. Study 2 tested the relation between a trait's communicability and its presence in stereotypes of 4 Canadian ethnic groups. Study 3 tested the relation between a trait's communicability and its persistence over time in stereotypes of 8 American ethnic groups. Results supported the hypotheses. A communication-based analysis of stereotypes appears helpful in predicting persistence and change in the contents of stereotypes of real groups in the real world.

2013-01-01

The aim of the current study was to investigate verbal communication skills in children with typical language development and ages between 6 and 8 years. Participants were 10 children of both genders in this age range without language alterations. A 30-minute video of each child's interaction with an adult (father and/or mother) was recorded, fully transcribed, and analyzed by two trained researchers in order to determine reliability. The recordings were analyzed according to a protocol that categorizes verbal communicative abilities, including dialogic, regulatory, narrative-discursive, and non-interactive skills. The frequency of use of each category of verbal communicative ability was analyzed (in percentage) for each subject. All subjects used more dialogical and regulatory skills, followed by narrative-discursive and non-interactive skills. This suggests that children in this age range are committed to continue dialog, which shows that children with typical language development have more dialogic interactions during spontaneous interactions with a familiar adult.

Wołk, Krzysztof; Wołk, Agnieszka; Glinkowski, Wojciech

2017-01-01

People with speech, hearing, or mental impairment require special communication assistance, especially for medical purposes. Automatic solutions for speech recognition and voice synthesis from text are poor fits for communication in the medical domain because they are dependent on error-prone statistical models. Systems dependent on manual text input are insufficient. Recently introduced systems for automatic sign language recognition are dependent on statistical models as well as on image and gesture quality. Such systems remain in early development and are based mostly on minimal hand gestures unsuitable for medical purposes. Furthermore, solutions that rely on the Internet cannot be used after disasters that require humanitarian aid. We propose a high-speed, intuitive, Internet-free, voice-free, and text-free tool suited for emergency medical communication. Our solution is a pictogram-based application that provides easy communication for individuals who have speech or hearing impairment or mental health issues that impair communication, as well as foreigners who do not speak the local language. It provides support and clarification in communication by using intuitive icons and interactive symbols that are easy to use on a mobile device. Such pictogram-based communication can be quite effective and ultimately make people's lives happier, easier, and safer.

2014-01-01

Full Text Available In this paper, subject-specific narrowband (2.45 GHz and ultra-wideband (3–10.6 GHz on-body radio propagation studies in wireless body area networks (WBANs were performed by characterizing the path loss for eight different human subjects of different shapes and sizes. The body shapes and sizes of the test subjects used in this study are characterised as thin, medium build, fatty, shorter, average height and taller. Experimental investigation was made in an indoor environment using a pair of printed monopoles (for the narrowband case and a pair of tapered slot antennas (for the ultra-wideband (UWB case. Results demonstrated that, due to the different sizes, heights and shapes of the test subjects, the path loss exponent value varies up to maximum of 0.85 for the narrowband on-body case, whereas a maximum variation of the path loss exponent value of 1.15 is noticed for the UWB case. In addition, the subject-specific behaviour of the on-body radio propagation channels was compared between narrowband and UWB systems, and it was deduced that the on-body radio channels are subject-specific for both narrowband and UWB system cases, when the same antennas (same characteristics are used. The effect of the human body shape and size variations on the eight different on-body radio channels is also studied for both the narrowband and UWB cases.

Organising Documentation in Knowledge Evolution and Communication

Full Text Available The knowledge of a subject evolves in time due to many factors, such as better understanding, study of additional issues within the same subject, study of related work from other themes, etc. This can be achieved by individual work, direct cooperation with other people and, in general, knowledge sharing. In this context, and in the broader context of knowledge communication, the appropriate organisation of documentation plays a fundamental role, but is often very difficult to achieve. A layered architecture is here proposed for the development of a structured repository of documentation, here called knowledge-bibliography KB. The process of knowledge acquisition, evolution and communication is firstly considered, then the distributed nature of nowadays knowledge and the ways it is shared and transferred are taken into account. On the basis of the above considerations, a possible clustering of documentation collected by many people is defined. An LDAP-based architecture for the implementation of this structure is also discussed.

Calm, compassionate clinicians comfort others. To evaluate the direct psychophysiologic benefits of non-verbal communication of compassion (NVCC), it is important to minimize the effect of subjects' expectation. This preliminary study was designed to a) test the feasibility of two strategies for maintaining subject blinding to non-verbal communication of compassion (NVCC), and b) determine whether blinded subjects would experience psychophysiologic effects from NVCC. Subjects were healthy volunteers who were told the study was evaluating the effect of time and touch on the autonomic nervous system. The practitioner had more than 10 years' experience with loving-kindness meditation (LKM), a form of NVCC. Subjects completed 10-point visual analog scales (VAS) for stress, relaxation, and peacefulness before and after LKM. To assess physiologic effects, practitioners and subjects wore cardiorespiratory monitors to assess respiratory rate (RR), heart rate (HR) and heart rate variability (HRV) throughout the 4 10-minute study periods: Baseline (both practitioner and subjects read neutral material); non-tactile-LKM (subjects read while the practitioner practiced LKM while pretending to read); tactile-LKM (subjects rested while the practitioner practiced LKM while lightly touching the subject on arms, shoulders, hands, feet, and legs); Post-Intervention Rest (subjects rested; the practitioner read). To assess blinding, subjects were asked after the interventions what the practitioner was doing during each period (reading, touch, or something else). Subjects' mean age was 43.6 years; all were women. Blinding was maintained and the practitioner was able to maintain meditation for both tactile and non-tactile LKM interventions as reflected in significantly reduced RR. Despite blinding, subjects' VAS scores improved from baseline to post-intervention for stress (5.5 vs. 2.2), relaxation (3.8 vs. 8.8) and peacefulness (3.8 vs. 9.0, P non-tactile LKM.

2013-03-12

The role of the pharmacist as a "communicator" of information and advice between patients, other healthcare practitioners, and the community is recognized as a vital component of the responsibilities of a practicing pharmacist. Pharmacy education is changing to reflect this, although the difficulty is in designing a curriculum that is capable of equipping students with the necessary knowledge and skills, using activities that are effective in promoting communication competency. The objective of this review was to identify published, peer-reviewed articles concerning communication training in pharmacy education programs, and describe which communication skills the structured learning activities aimed to improve and how these learning activities were assessed. A systematic literature search was conducted and the articles found were analyzed and divided into categories based on specific communication skills taught and type of learning activity used. Oral interpersonal communication skills targeted at patients were the most common skill-type described, followed by clinical writing skills. Common teaching methods included simulated and standardized patient interactions and pharmacy practice experience courses. Most educational interventions were assessed by subjective measures. Many interventions were described as fragments, in isolation of other learning activities that took place in a course, which impedes complete analysis of study results. To succeed in communication training, integration between different learning activities and progression within pharmacy educations are important.

Scheinfeld, Emily; Shim, Minsun

2017-05-01

Emerging adulthood (EA) is an important yet overlooked period for developing long-term health behaviors. During these years, emerging adults adopt health behaviors that persist throughout life. This study applies the Integrative Model of Behavioral Prediction (IMBP) to examine the role of childhood parental communication in predicting engagement in healthful eating during EA. Participants included 239 college students, ages 18 to 25, from a large university in the southern United States. Participants were recruited and data collection occurred spring 2012. Participants responded to measures to assess perceived parental communication, eating behaviors, attitudes, subjective norms, and behavioral control over healthful eating. SEM and mediation analyses were used to address the hypotheses posited. Data demonstrated that perceived parent-child communication - specifically, its quality and target-specific content - significantly predicted emerging adults' eating behaviors, mediated through subjective norm and perceived behavioral control. This study sets the stage for further exploration and understanding of different ways parental communication influences emerging adults' healthy behavior enactment.

Until now, the prescription of communication devices for disabled people has been dependent on the experience of technical experts who are working for them. To improve this situation, the aim of present study is to develop the objective methods for evaluating satisfaction of communication devices. Further aim of this study is to get the basic data for using electroencephalogram for thinking switch of communication devices. 1) Under imaging real communication devices, the menu of two experimental subjects were designed with three tasks which have different difficulty. Five physiological indexes (heart rate, coefficient of variation of R-R intervals, respiration rate, skin temperature and plethysmograph), which are known to closely correlated with mental stress, were studied during three different tasks in each experimental subject. In addition, psychological test were also performed before and after each tasks. In the first subject a significant difference was detected only in psychological test among three tasks. This result may come from the small difference of difficulty in each tasks of the first subject. In the second subject, significant differences were observed in the coefficient of variation of R-R intervals, the respiration rate and psychological test. Other physiological indexces, skin temperature, heart rate and plethysmograph, may be useful. However, the reconsideration will be needed to find the usefulness of these indexes for evaluating mental stress. 2) Biofeedback control of mu rhysm, an electrical brain wave, was investigated for the possibility of thinking switch in three graduate students. In one of three students, changes of amplitude were observed bilaterally although we had expected the unilateral change. Further studies will be needed to clarify the best method of biofeedback experiment. (NEDO)

Dependent on subsidiarity and decentralization, European Years focus on a specific issue which constitutes the subject of a year-long awareness campaign. Beyond the involvement of Europe’s citizens through their local, regional and national authorities in the implementation of the European Years’ policies, there is a unity at the level of the visual communication of the EU by two important image-building elements: EY logos and communication toolboxes. The European Years’ communication toolboxes can be considered signs of inclusion since every organization is expected to customize the templates in the official campaign design of the European Year.

Titmarsh, Drew M.; Chen, Huaying; Glass, Nick R.; Cooper-White, Justin J.

2014-01-01

Stem cells are a powerful resource for producing a variety of cell types with utility in clinically associated applications, including preclinical drug screening and development, disease and developmental modeling, and regenerative medicine. Regardless of the type of stem cell, substantial barriers to clinical translation still exist and must be overcome to realize full clinical potential. These barriers span processes including cell isolation, expansion, and differentiation; purification, quality control, and therapeutic efficacy and safety; and the economic viability of bioprocesses for production of functional cell products. Microfluidic systems have been developed for a myriad of biological applications and have the intrinsic capability of controlling and interrogating the cellular microenvironment with unrivalled precision; therefore, they have particular relevance to overcoming such barriers to translation. Development of microfluidic technologies increasingly utilizes stem cells, addresses stem cell-relevant biological phenomena, and aligns capabilities with translational challenges and goals. In this concise review, we describe how microfluidic technologies can contribute to the translation of stem cell research outcomes, and we provide an update on innovative research efforts in this area. This timely convergence of stem cell translational challenges and microfluidic capabilities means that there is now an opportunity for both disciplines to benefit from increased interaction.

Promoting open access to science through effective communication

Science.gov (United States)

Egger, A. E.

2006-12-01

Geology is a difficult subject to communicate effectively. Many people associate geology with memorizing rock and mineral names and not with dynamic earth processes. Even more challenging for the non-geologist is the concept of deep time, and why processes that happened millions of years ago are important to us today. Additionally, many people view science itself as inaccessible and difficult. And yet, geology is a naturally accessible subject, as it is all around us. In order to communicate effectively, geologists must convince others that their work is both accessible and relevant, even though it may not directly generate economic benefits or lend insight into solutions for our modern problems like climate change. As scientists, we know the connections are there, but convincing others requires creating face-to-face, positive interactions through the use of active techniques to help bring the audience to an understanding of the process of science in addition to the subject matter itself. My overarching motive for creating and participating in communication activities with a broad audience is thus to demonstrate that science is accessible to everyone, that a scientific way of thinking can be both fun and useful, and that a little knowledge about geology can give you a new perspective on the world. Using this motivation as a guiding principle regardless of the specific audience, two techniques are important to make the communication effective. First, whenever possible, I conduct activities in the field (broadly speaking), or at least bring the field into the talk, and model the scientific process by asking for participation. This allows the audience to fully understand how geologic work is done, including the mundane and the mistakes. Second, I take my audience seriously, including all questions and observations, in order to build confidence in everyone that they are able to contribute to and understand both geology and the scientific process in general. Despite the

Strategic Communication and its Utility in Ecosystem Service ...

Science.gov (United States)

The field of Strategic Communication involves a focused effort to identify, develop, and present multiple types of communication media on a given subject. A Strategic Communication program recognizes the limitations of the most common communication models (primarily “one size fits all” and “presenting everything and letting the audience decide what is important”) and specifically focuses on building a communication framework that is composed of three interlinked pillars: message – Identifying the right content for a given audience and a vehicle; audience – Identify the right target group for a given message and vehicle; vehicle – Identifying the right types of media for a given message and audience. In addition to serving as an organizational framework, the physical structure of a Strategic Communication plan also can serve as a way to show an audience where they, the message, and vehicle fit into the larger picture (i.e., “you are here”). This presentation will explore the process of designing a Strategic Communication plan and examine some examples of its utility in the field of ecosystem services science. Ideally, a strategic communication matrix can be utilized to identify and access the materials of interest for any given activity (i.e., avoids the need to recreate materials or use the wrong materials for the wrong audience). Challenges in implementation will also be explored. Abstract for ACES conference

Systematic review of communication partner training in aphasia: methodological quality.

Science.gov (United States)

Cherney, Leora R; Simmons-Mackie, Nina; Raymer, Anastasia; Armstrong, Elizabeth; Holland, Audrey

2013-10-01

Twenty-three studies identified from a previous systematic review examining the effects of communication partner training on persons with aphasia and their communication partners were evaluated for methodological quality. Two reviewers rated the studies on defined methodological quality criteria relevant to each study design. There were 11 group studies, seven single-subject participant design studies, and five qualitative studies. Quality scores were derived for each study. The mean inter-rater reliability of scores for each study design ranged from 85-93%, with Cohen's Kappa indicating substantial agreement between raters. Methodological quality of research on communication partner training in aphasia was highly varied. Overall, group studies employed the least rigorous methodology as compared to single subject and qualitative research. Only two of 11 group studies complied with more than half of the quality criteria. No group studies reported therapist blinding and only one group study reported participant blinding. Across all types of studies, the criterion of treatment fidelity was most commonly omitted. Failure to explicitly report certain methodological quality criteria may account for low ratings. Using methodological rating scales specific to the type of study design may help improve the methodological quality of aphasia treatment studies, including those on communication partner training.

Method: 73 subjects, 33 in the experimental group, with diagnosis of PD, and 40 subjects in the control group, healthy and without vocal complaints. They underwent the following procedures: application of the Voice Symptons Scale – VoiSS – Brazilian Version, Voice Disability Coping Questionnaire – VDCQ – Brazilian Version, and the questionnaire Living with Dysarthria – LwD. Results: The experimental group showed deviations in all protocols: VDCQ (p<0.001, VoiSS (p<0.001, LwD (p<0.001. The most frequently used coping strategy was self-control (p<0.001. The correlation between vocal symptoms and communicative aspects showed that the greater the impairment in communication, the greater the VoiSS emotional scores and the greater will be the amount of voice symptoms and signs. However, the vocal signs and symptoms and communicative aspects showed no correlation with coping. Conclusion: Patients with PD have a high amount of vocal signs and symptoms and the higher the occurrence, the more the patient reports being difficult to live with dysarthria, particularly when there are deviations in the emotional domain.

Full Text Available This article intended to reveal the results of a survey study in which the students’ attitudes toward online communication in open and distance learning were investigated. In the study, affects of the students’ gender and computer experience on their attitudes were also examined. A total of 626 subjects participated in the study and ‘Online Communication Attitude Scale’, developed by Ledbetter, was adapted as the data collection instrument. Mean, standard deviation, independent t-test, one-way analysis of variance and Tukey HSD tests were used to analyze the data gathered. The results of the study indicated that students have in general positive attitudes toward online communication in ODL. Also, it showed that there is a significant difference in ‘miscommunication’, ‘social connection’ and ‘ease’ dimensions of online communication between the males and the female students. The female students see online environments as open to communication errors. On the other hand, the study supported the literature about the affect of the students’ computer experience and their attitudes toward online communication in ODL.

Assessing students' communication skills: validation of a global rating.

Scheffer, Simone; Muehlinghaus, Isabel; Froehmel, Annette; Ortwein, Heiderose

2008-12-01

Communication skills training is an accepted part of undergraduate medical programs nowadays. In addition to learning experiences its importance should be emphasised by performance-based assessment. As detailed checklists have been shown to be not well suited for the assessment of communication skills for different reasons, this study aimed to validate a global rating scale. A Canadian instrument was translated to German and adapted to assess students' communication skills during an end-of-semester-OSCE. Subjects were second and third year medical students at the reformed track of the Charité-Universitaetsmedizin Berlin. Different groups of raters were trained to assess students' communication skills using the global rating scale. Validity testing included concurrent validity and construct validity: Judgements of different groups of raters were compared to expert ratings as a defined gold standard. Furthermore, the amount of agreement between scores obtained with this global rating scale and a different instrument for assessing communication skills was determined. Results show that communication skills can be validly assessed by trained non-expert raters as well as standardised patients using this instrument.

Lost in Interpretation – Communicating Risk to the Public

2016-01-01

Communicating radiation incidents and emergencies to the public always has been challenging. No other type of emergency is related to such disproportional risk perception, so little public knowledge about the subject matter and so many contradicting expert analyses when it comes to public communications. The rise of social media and citizen journalism resulted in a dramatic acceleration of global communications and widespread misinformation. News does not break on television anymore but on Twitter, Facebook & Co. As a consequence, professional communicators not only have to take initiative considerably faster than in the past and deal with rumours. Their message has to be brief and on the point and is sometimes limited to just some 140 characters, the maximum length of a Tweet. More than ever it is essential to timely communicate in plain language and to clearly tell what needs to be done to be safe and to remain safe. Otherwise, the public will be lost in interpretation.

This paper presents the results of a large study of 1340 articles published by two major newspapers in six European countries (Belgium, Italy, Norway, Slovenia, Spain and Russia) in the first 2 months after the Fukushima Daiichi nuclear disaster. The focus of the analysis is on the application and overall impact of protective actions, both during the emergency phase and later, how the newspapers describe those actions, which differences were apparent between countries and what recommendations can be extracted in order to improve general communication about these issues. A clear lesson is that, even under uncertainty and recognising limitations, responsible authorities need to provide transparent, clear and understandable information to the public and the mass media right from the beginning of the early phase of any nuclear emergency. Clear, concise messages should be given. Mass media could play a key role in reassuring the public if the countermeasures are clearly explained. © The Author 2016.

To investigate, in patients with Parkinson's disease (PD), the coping strategies; the most reported vocal symptoms; and the relation between coping, voice symptoms, and communicative aspects. Seventy-three subjects were included in the sample, 33 of which were participants in the experimental group (EG) with diagnosis of PD and 40 were control subjects, that is, healthy and without vocal complaints. They underwent the following procedures: application of Voice Symptoms Scale (VoiSS), Brazilian Version; Voice Disability Coping Questionnaire (VDCQ), Brazilian Version; and the questionnaire Living with Dysarthria (LwD). The EG presented deviations in all protocols: VDCQ, with the most frequently coping strategy being "self-control," VoiSS, with "Impairment" as the most prevalent domain, and LwD, presenting changes in all sections. Vocal signs and symptoms and communicative aspects were shown to have a regular correlation with coping. The correlation between vocal symptoms and communicative aspects was as follows: the greater the impairment in communication, the greater the VoiSS emotional scores and the more they complaint of voice-related signs and symptoms. Patients with PD use all kinds of coping strategies, but prefer using self-control. They present several vocal signs and symptoms, and "Impairment" was the most prevalent domain. There are difficulties in all aspects of communication. The higher the occurrence of vocal signs and symptoms, the more the patient reports the difficulties of living with dysarthria, particularly when deviations affect the emotional domain.

Full Text Available The article is devoted to the analysis of such specific forms of human interaction as quasi- and pseudo-communication. The authors specify the terms which sometimes are used interchangeably. The aim of the conducted research is to find out and demonstrate existing differences and similarities of these communicative phenomena on the basis of theoretical and empirical analysis of the research material in the Russian and English languages. The authors describe communicative features of these phenomena and consider the reasons for such forms of communication and their increased use at present. The research material is represented fiction extracts, film scripts, jokes, print media, a collection of oral speech records both in Russian and English. The authors make use of the following research methods: definitional analysis (to define the terminology of the research, the method of linguistic observation and introspection (to select the communicative situations, the descriptive-analytical method and the method of comparative analysis (to identify similarities and differences of the target phenomena, and the conversational analysis method (to view productivity and effectiveness of a dialogue, etc. The classification of possible forms of their existence in different discourses is suggested. The authors assume that both pseudo- and quasi-communication are characterized as fictitious forms of human interaction with some noticeable violation of the basic communicative model. Pseudo-communication suffers from the discrepancy of the meaning of a coded and decoded message. The authors put forward the main parameters of scientific classification of it as follows: adequate understanding, intentionality, and the stage of communicative action where the failure takes place. At the same time they stress the necessity to distinguish the cases of pseudo talks from phatic and indirect communication. Quasi-communcation is marked by the lack of a real partner and hence

From the cognitive to the pragmatic: the scientist as communicator

OpenAIRE

Pérez-Llantada Auría, Carmen

2001-01-01

The main contention in this paper is that the process of communicating scientific knowledge could be compared to the role of the translator as communicator (Hatim & Masón, 1997). Like the translator, the task of the scientist is to encode —or metaphorically "translate"— the conceptualizations of science into a very restricted register with particular linguistic, pragmatic, and ideological conventions. The present analysis also shows how discourse is ultimately subject to certain social ...

character. Communicative competence is offered to be formed progressively, in the process of development among students of subject content of professional activity. It is shown that there is a change of ways and means of subject (cognitive and communicative activity at each grade level depending on objectives; in result, a professional consciousness of future expert appears. The specific role of two forms of consciousness is proved: cognitive is directed to detection of object of activity; communicative fixes the revealed contents in system of values. The conclusion is drawn on expediency of use for acquisition by students of communicative skills and abilities of activity model in which speech communications are inseparable from the purposes and motives of joint activity.Practical significance. The possibilities of development among students of terminological system of native and foreign languages as tools of the forthcoming professional activity are shown. It is summarized that the educational process in higher education institution aimed at the development of communicative competence promotes formation and development of professional consciousness and makes an essential contribution to development of the qualities necessary for the modern expert.

Pun, Jack Kh; Chan, Engle Angela; Murray, Kristen A; Slade, Diana; Matthiessen, Christian Mim

2017-11-01

To understand the challenges that clinicians face in communicating with patients and other clinicians within a Hong Kong trilingual emergency department. Effective communication has long been recognised as fundamental to the delivery of quality health care, especially in high-risk and time-constrained environments such as emergency departments. The issue of effective communication is particularly relevant in Hong Kong emergency departments, due to the high volume of patients and the linguistic complexity of this healthcare context. In Hong Kong, emergency department clinicians are native speakers of Chinese, but have received their medical training in English. The clinicians read and record virtually all of their medical documentation in English, yet they communicate verbally with patients in Cantonese and Mandarin. In addition, communication between clinicians occurs in spoken Cantonese, mixed with medical English. Thus, medical information is translated numerous times within one patient journey. This complex linguistic environment creates the potential for miscommunication. A mixed-methods design consisting of a quantitative survey with a sequential qualitative interview. Data were collected in a survey from a purposive sample of 58 clinicians and analysed through descriptive statistics. Eighteen of the clinicians were then invited to take part in semi-structured interviews, the data from which were then subjected to a manifest content analysis. Nearly half of the clinicians surveyed believed that medical information may be omitted or altered through repeated translation in a trilingual emergency department. Eighty-three per cent of clinicians stated that there are communication problems at triage. Over 40% said that they have difficulties in documenting medical information. Around 50% believed that long work hours reduced their ability to communicate effectively with patients. In addition, 34% admitted that they rarely or never listen to patients during a

Simultaneous Communication and Cochlear Implants in the Classroom?

Science.gov (United States)

Blom, Helen C; Marschark, Marc

2015-09-01

This study was designed to evaluate the potential of simultaneous communication (sign and speech together) to support classroom learning by college students who use cochlear implants (CIs). Metacognitive awareness of learning also was evaluated. A within-subjects design involving 40 implant users indicated that the student participants learned significantly more when material was presented via simultaneous communication than spoken language overall, but a statistical interaction indicated that the difference held only with more difficult material. Learning in the speech-only condition was positively related to the students' spoken language skills, their confidence with spoken language, and their receptive simultaneous communication skills. Learning in that condition was negatively related to the age at which the participants learned to sign. Findings were interpreted to indicate that simultaneous communication can be beneficial for classroom learning by college students with CIs, at least with more complex material or when information redundancy is otherwise important. Further research is needed to determine who is likely to benefit in what settings.

Risk communication about the high-level radioactive waste (HLW) disposal is necessary for public acceptance of HLW disposal program. Online Risk Communication Assistant Tool (ORCAT) system is developed in order to support risk communication for HLW disposal on World Wide Web. We have been evaluating ORCAT system. After two test operations, we carried out the third test operation from Aug. 29 to Dec. 12, 2005. In the third test operation, 100 participants answered the questionnaires about the attitude change and knowledge. We classified the participants into two groups by the analysis on the number of login a week, and analyzed the change of the amount of subjective and objective knowledge. In the result of analysis on knowledge, the increase of amount of subjective knowledge doesn't always carried the increase of amount of objective knowledge. On the whole we found that the ORCAT system is evaluated useful to the risk communication about the HLW disposal. (author)

2008-01-01

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.

The associations among computer-mediated communication, relationships, and well-being.

Schiffrin, Holly; Edelman, Anna; Falkenstern, Melissa; Stewart, Cassandra

2010-06-01

Social support provided by interpersonal relationships is one of the most robust correlates of well-being. Self-disclosure serves as a basic building block of these relationships. With the rapid growth of the Internet in recent years, the question remains how self-disclosure, and subsequently relationships and well-being, differ when people communicate over the Internet rather than in person. The purpose of this article is to describe current Internet usage patterns as well as explore the association of Internet usage and well-being. Additionally, it directly compares the perceived benefits of face-to-face communication and computer-mediated communication. A questionnaire was administered to 99 undergraduates to measure Internet usage patterns, communication partners, self-disclosure, extraversion, and subjective well-being. Although Internet communication was found to be common, individuals perceived computer-mediated communication to be less useful than face-to-face communication. In addition, increased Internet usage was associated with decreased well-being. Implications are discussed in terms of a new Internet paradox in which people increasingly use the Internet for communication, although they perceive it to be less beneficial than face-to-face interactions and it is associated with reduced well-being.

Communications Training in Pharmacy Education, 1995-2010

The role of the pharmacist as a “communicator” of information and advice between patients, other healthcare practitioners, and the community is recognized as a vital component of the responsibilities of a practicing pharmacist. Pharmacy education is changing to reflect this, although the difficulty is in designing a curriculum that is capable of equipping students with the necessary knowledge and skills, using activities that are effective in promoting communication competency. The objective of this review was to identify published, peer-reviewed articles concerning communication training in pharmacy education programs, and describe which communication skills the structured learning activities aimed to improve and how these learning activities were assessed. A systematic literature search was conducted and the articles found were analyzed and divided into categories based on specific communication skills taught and type of learning activity used. Oral interpersonal communication skills targeted at patients were the most common skill-type described, followed by clinical writing skills. Common teaching methods included simulated and standardized patient interactions and pharmacy practice experience courses. Most educational interventions were assessed by subjective measures. Many interventions were described as fragments, in isolation of other learning activities that took place in a course, which impedes complete analysis of study results. To succeed in communication training, integration between different learning activities and progression within pharmacy educations are important. PMID:23519011

2012-01-01

Full Text Available Interdisciplinary and meta-disciplinary integration in education reflects a comprehensive approach to education and training, and makes it possible to single out both the main elements of educational content and subject interrelations, re solving the problem of fragmentation and isolation of different subjects. The paper considers the way of improving students’ bilingual communicative competence by means of implementing interdisciplinary and meta-disciplinary integration in teaching process. By the above competence the authors understand the readiness and ability to perform effective interpersonal, inter-group and inter-cultural communication both in native and foreign languages. The paper describes the meta-disciplinary principle that involves school training of general methods, techniques, schemes and mental work patterns used in working with any materials in any sphere of knowledge, and not lim- ited by specific subjects. The authors recommend the culture dialog as the condition, means and way of personal development in learning native and foreign languages. Bilingual informational, cultural and semantic interrelations, comparison of cultures and languages stimulate students’ cognitive process actualizing their personal experience, facilitating both socio-linguistic and socio-cultural discursive knowledge, providing the effective development of communication skills. The example of meta-disciplinary integration is given demonstrating the students’ communicative competence development in the process of training for the creative part of the unified state examinations in the Russian and English languages.

Physiological and psychological responses to expressions of emotion and empathy in post-stress communication.

Ono, Makiko; Fujita, Mizuho; Yamada, Shigeyuki

2009-01-01

The effects of communicating during and after expressing emotions and receiving empathy after exposure to stress were investigated for 18 female students (9 pairs). After mental and physical tasks, a subject spoke to a listener about the stress task. In Experiment 1, responses to speaking about negative emotions aroused by the task (the "with emotion" condition) were compared to speaking about only objective facts about the task (the control). In Experiment 2, responses to empathetic reactions from the listener (the "with empathy" condition) were compared to no reaction (the control). Electroencephalograms were recorded, and heart rate variability (HRV) was calculated from electrocardiogram data. Subjective stress was estimated by a visual analog scale. Experiment 1 demonstrated that expressing emotions activated the left temporal region (T3) in the "with emotion" condition. In Experiment 2, physiological responses depended on cognition of different elements of empathy. During communication, feeling that the listener had the same emotion decreased the subject's T3 activity and sympathetic activity balance indicated by HRV. After communication, feeling that the listener understood her emotions decreased bilateral frontal and temporal activity. On the other hand, subjective stress did not differ between conditions in both experiments. These findings indicate that the comfort of having shared a message reduced physiological activity, especially in the "with empathy" condition. Conversely, even in the "with empathy" condition, not sharing a message can result in more discomfort or stress than the control. Sharing might be associated with cognition of the degree of success of communication, which reflected in the physiological responses. In communication, therefore, expressing emotions and receiving empathy did not in themselves reduce stress, and the level of cognition of having shared a message is a key factor in reducing stress.

Measurement of left-to-right shunts by gated radionuclide angiography: concise communication

International Nuclear Information System (INIS)

Rigo, P.; Chevigne, M.

1982-01-01

Gated cardiac blood-pool scans allow comparison of left- and right-ventricular stroke volume. We have applied these measurements to the quantification of left-to-right shunts (QP/QS) in nine patients with atrial septal defects, one patients with partial anomalous pulmonary venous return, four patients with ventricular septal defects, and two patients with patent ductus arteriosus. None of these patients had combined lesions. QP/QS was measured as the right-ventricular (RV) stroke counts divided by the left-ventricular (LV) stroke counts and as the LV stroke counts divided by the RV stroke counts in patients with RV and LV diastolic volume overload respectively. All patients had also QP/QS measurements by oximetry and first-pass radionuclide angiography. The stroke-count measurements indicated the overloaded ventricle in all patients. QP/QS determined by equilibrium gated studies correlated well with those obtained by oximetry (r . 0.79). Reproducibility of the equilibrium measurements was good. We conclude that gated cardiac blood-pool scans can measure left-to-right shunts and can distinguish between shunts with RV and LV volume overload

The atrial myocardium has been barely visible with thallium-201 myocardial scintigraphy. This is probably related to the difference in size, distance from anterior chest wall, and small coronary blood flow of the atrium, compared with the ventricle. We have encountered eight cases of visualization of the right atrial appendix (RAA). The RAA was identified from multiple projections in all cases and sometimes confirmed by radionuclide angiocardiography. Evidence derived from ECG, chest radiographs, and cardiac catheterization, indicated that the most important factor in the visualization might be the displacement of the RAA to a more anterior position

Comparative cardiac effects of three hepatobiliary radiopharmacologicals in the dog: concise communication

International Nuclear Information System (INIS)

Shani, J.; Sarel, O.; Rogel, S.; Weininger, J.; Lubin, E.

1982-01-01

Three hepatobiliary agents with an acetanilide-imidoacetic-acid moiety resembling that in lidocaine were investigated for their possible effects on contractility and conductivity in the heart and on arterial pressure and aortic blood flow. This was done in the light of lidocaine's numerous cardiac side effects. HIDA, BIDA, and DIPA, each with traces of decayed /sup 99m/Tc, were injected i.v. into anesthetized dogs with an A-V block, and their effects on the above parameters were followed until control levels were reestablished. Whereas lidocaine raises the diastolic threshold and prolongs the refractory period, the three agents tested do not prolong myocardial conductivity. Both HIDA and BIDA have an effect similar to that of lidocaine, but DIPA has no effect on the latter two parameters. Moreover, whereas lidocaine depressed myocardial contractility, blood pressure, and blood flow, HIDA has a less prominent effect on these parameters, and neither BIDA nor DIPA has any such effect. It is concluded that even though the effect of HIDA on the heart is milder than that of lidocaine, the effects of both BIDA and DIPA are even less pronounced, and they are less likely to cause cardiac side effects when similar doses are administered during nuclear medicine procedures

Single-gamma emission computerized tomography (ECT) was compared with transmission computerized tomography (TCT) and scintillation-camera imaging (SC) in eight dogs with acute, solitary hematomas in the left liver lobe. The superior performance of TCT was attributed to its inherently better spatial resolution than those of ECT or SC, and to the fact that studies with TCT could be performed during apnea. ECT was more sensitive than SC to small changes in the spatial distribution of radionuclides. In addition, the ECT, by virtue of its sectioning capability, was more sensitive than is SC to differences in radionuclide concentrations at the same depth in an organ

Manoranjan, M D; Robinson, J A

2000-03-01

Deaf sign language transmitted by video requires a temporal resolution of 8 to 10 frames/s for effective communication. Conventional videoconferencing applications, when operated over low bandwidth telephone lines, provide very low temporal resolution of pictures, of the order of less than a frame per second, resulting in jerky movement of objects. This paper presents a practical solution for sign language communication, offering adequate temporal resolution of images using moving binary sketches or cartoons, implemented on standard personal computer hardware with low-cost cameras and communicating over telephone lines. To extract cartoon points an efficient feature extraction algorithm adaptive to the global statistics of the image is proposed. To improve the subjective quality of the binary images, irreversible preprocessing techniques, such as isolated point removal and predictive filtering, are used. A simple, efficient and fast recursive temporal prefiltering scheme, using histograms of successive frames, reduces the additive and multiplicative noise from low-cost cameras. An efficient three-dimensional (3-D) compression scheme codes the binary sketches. Subjective tests performed on the system confirm that it can be used for sign language communication over telephone lines.

The Essential Elements of Communication (EEC) were developed from the Kalamazoo consensus statement on physician-patient communication. The Uniformed Services University of the Health Sciences (USU) has adopted a longitudinal curriculum to use the EEC both as a learning tool during standardized patient encounters and as an evaluation tool culminating with the end of preclerkship objective-structured clinical examinations (OSCE). Medical educators have recently emphasized the importance of teaching communication skills, as evidenced by the United States Medical Licensing Examination testing both the integrated clinical encounter (ICE) and communication and interpersonal skills (CIS) within the Step 2 Clinical Skills exam (CS). To determine the associations between students' EEC OSCE performance at the end of the preclerkship period with later communication skills assessment and evaluation outcomes in the context of a longitudinal curriculum spanning both undergraduate medical education and graduate medical education. Retrospective data from preclerkship (overall OSCE scores and EEC OSCE scores) and clerkship outcomes (internal medicine [IM] clinical points and average clerkship National Board of Medical Examiners [NBME] scores) were collected from 167 USU medical students from the class of 2011 and compared to individual scores on the CIS and ICE components of Step 2 CS, as well as to the communication skills component of the program directors' evaluation of trainees during their postgraduate year 1 (PGY-1) residency. In addition to bivariate Pearson correlation analysis, we conducted multiple linear regression analysis to examine the predictive power of the EEC score beyond the IM clerkship clinical points and the average NBME Subject Exams score on the outcome measures. The EEC score was a significant predictor of the CIS score and the PGY-1 communication skills score. Beyond the average NBME Subject Exams score and the IM clerkship clinical points, the EEC score

This experimental study examined differences in doctor-patient relationships according to the health communication strategies during cases of medical malpractices occurred at primary medical institution. A total of 116 subjects aged in their 20s-50s was sampled. The first medical malpractice scenario chosen was the medical malpractice case most frequently registered at the Korean Medical Association Mutual Aid and the second scenario was associated with materials and devices as the cause of malpractice. Four types of crisis communication strategy messages were utilized, consisting of denial, denial + ingratiation, apology, and apology + ingratiation. Subjects were classified into four research groups by crisis communication strategy to measure levels of trust, control mutuality, commitment, and satisfaction, before and after the occurrence of medical malpractice and application of communication strategies. The findings of this study revealed that the apology strategy, compared with the denial strategy, showed a smaller difference before and after the application of communication strategies in all variables of trust (F = 8.080, F = 5.768), control mutuality (F = 8.824, F = 9.081), commitment (F = 9.815, F = 8.301), and satisfaction (F = 8.723, F = 5.638). Further, a significant interaction effect was shown between variables. The apology strategy, compared with the denial strategy, was effective in the improvement of doctor-patient relationships in both Scenarios I and II. For Scenario I, the apology strategy without ingratiation boosted commitment and satisfaction, but for Scenario II, utilizing the apology strategy with ingratiation boosted the effectiveness of trust and commitment.

Depression may adversely affect health outcomes by influencing doctor-patient communication. We aimed to determine the association between depressive symptoms and doctor-patient communication among patients presenting to the emergency department (ED) with a suspected acute coronary syndrome (ACS). We enrolled a consecutive sample of 500 patients evaluated for ACS symptoms from the ED of an urban medical center. Depressive symptoms (8-item Patient Health Questionnaire, PHQ-8) and doctor-patient communication in the ED (Interpersonal Processes of Care) were assessed during hospitalization. Logistic regression was used to determine the association between depressive symptoms and doctor-patient communication, adjusting for age, sex, race, ethnicity, education, language, health insurance status and comorbidities. Compared to nondepressed patients, depressed patients (PHQ-8≥10) were more likely (Pcommunication on five of seven communication domains: clarity, elicitation of concerns, explanations, patient-centered decision making and discrimination. A greater proportion of depressed versus nondepressed patients reported suboptimal overall communication (39.8% versus 22.9%, Pcommunication (adjusted odds ratio 2.42, 95% confidence interval 1.52-3.87; Pcommunication in the ED than nondepressed patients. Research is needed to determine whether subjectively rated differences in communication are accompanied by observable differences. Copyright © 2016 Elsevier Inc. All rights reserved.

Written mathematical communication is the process of expressing mathematical ideas and understanding in writing. It is one of the important aspects that must be mastered by the prospective math teacher as tool of knowledge transfer. This research was a qualitative research that aimed to describe the mathematical communication profile of the prospective mathematics teacher in mathematical proving. This research involved 48 students of Mathematics Education Study Program; one of them with moderate math skills was chosen as the main subject. Data were collected through tests, assignments, and task-based interviews. The results of this study point out that in the proof of geometry, the subject explains what is understood, presents the idea in the form of drawing and symbols, and explains the content/meaning of a representation accurately and clearly, but the subject can not convey the argument systematically and logically. Whereas in the proof of algebra, the subject describes what is understood, explains the method used, and describes the content/meaning of a symbolic representation accurately, systematically, logically, but the argument presented is not clear because it is insufficient detailed and complete.

Construction of Subjectivity in Social Media

Directory of Open Access Journals (Sweden)

Anže Dolinar

2015-03-01

Full Text Available Social media are a phenomenon that came about with the Web 2.0. The essential characteristic of social media is the so-called user-generated content, which means that individuals and their lives are entangled in a social interaction in which their identity is to some extent subsumed under the logic of the production of profit. From the standpoint of the critique of political economy, the phenomenon of digital labor can be tackled with a digital labor theory of value. On the other hand, a question of a subjective aspect remains open. The initial hypothesis is that an analysis of a dynamic character of capitalism is necessarily connected with historical transformations of subjectivity. I will inspect which type of subjectivity is produced during the “process of production” on Facebook, how relations of the exchange of information and meaning take place inside this medium, and what kind of consciousness comes with this virtual identity. I will attempt to address this question with an explication of social forms of sharing amongst individuals on this social network. I will focus on how photos, notifications and comments structure web subjectivity and its function. Answers to such questions can help us in understanding a certain aspect of a socioeconomic structure of contemporary capitalism and bear an emancipatory potential in a possibility of negation of such social relations. The article will limit itself to the exploration of subjectivity in social media, which will be dealt with in a dynamic sense and in regard to formal conditions of communication inside social media, and in respect to a social situation in which they are.

IPCC reports provide a synthesis of the state of the science in order to inform the international policy process. This task is made difficult by the presence of deep uncertainty in the climate problem that results from long time scales and complexity. This paper focuses on how deep uncertainty can be effectively communicated. We argue that existing schemes do an inadequate job of communicating deep uncertainty and propose a simple approach that distinguishes between various levels of subjective understanding in a systematic manner. We illustrate our approach with two examples. (authors)

Zhao, Li; Chen, Lulu; He, Luwei; Heyman, Gail D

2017-09-01

We examined a range of forms of strategic communication relevant to academic performance among 151 seventh- and eleventh-grade adolescents in China. Participants were asked to rate the frequency of their engagement of strategic communication and to evaluate the possible motives for each strategy. The most commonly adopted strategy was to give a vague response about one's own performance, and the predominant motives for strategic communication were the desires to outcompete others, to be prosocial, and to be modest. Males were more likely than females to focus on gaining social approval, and eleventh graders were more likely than seventh graders to focus on being prosocial and modest when engaging in strategic communication. These findings provide insight into the development of strategic communication beyond Western culture. Statement of contribution What is already known on this subject? Adolescents in the West often hide their effort to appear more competent or to gain social acceptance. Little is known about other communication strategies related to academic performance. Little is known about the development of these strategies in non-Western samples. What does this study add? We show that in China, as in Western cultures, children often engage in strategic communication. We demonstrate links between different forms of strategic communication and specific motives. We demonstrate that strategic communication can be motivated by outcompeting others, by being prosocial, and by being modest. © 2017 The British Psychological Society.

Neural systems language: a formal modeling language for the systematic description, unambiguous communication, and automated digital curation of neural connectivity.

Science.gov (United States)

Brown, Ramsay A; Swanson, Larry W

2013-09-01

Systematic description and the unambiguous communication of findings and models remain among the unresolved fundamental challenges in systems neuroscience. No common descriptive frameworks exist to describe systematically the connective architecture of the nervous system, even at the grossest level of observation. Furthermore, the accelerating volume of novel data generated on neural connectivity outpaces the rate at which this data is curated into neuroinformatics databases to synthesize digitally systems-level insights from disjointed reports and observations. To help address these challenges, we propose the Neural Systems Language (NSyL). NSyL is a modeling language to be used by investigators to encode and communicate systematically reports of neural connectivity from neuroanatomy and brain imaging. NSyL engenders systematic description and communication of connectivity irrespective of the animal taxon described, experimental or observational technique implemented, or nomenclature referenced. As a language, NSyL is internally consistent, concise, and comprehensible to both humans and computers. NSyL is a promising development for systematizing the representation of neural architecture, effectively managing the increasing volume of data on neural connectivity and streamlining systems neuroscience research. Here we present similar precedent systems, how NSyL extends existing frameworks, and the reasoning behind NSyL's development. We explore NSyL's potential for balancing robustness and consistency in representation by encoding previously reported assertions of connectivity from the literature as examples. Finally, we propose and discuss the implications of a framework for how NSyL will be digitally implemented in the future to streamline curation of experimental results and bridge the gaps among anatomists, imagers, and neuroinformatics databases.

Costa, Nayara Thais de Oliveira; Martinho-Carvalho, Ana Claudia; Cunha, Maria Claudia; Lewis, Doris Ruthi

2012-01-01

This study had the aim to investigate the auditory and communicative abilities of children diagnosed with Auditory Neuropathy Spectrum Disorder due to mutation in the Otoferlin gene. It is a descriptive and qualitative study in which two siblings with this diagnosis were assessed. The procedures conducted were: speech perception tests for children with profound hearing loss, and assessment of communication abilities using the Behavioral Observation Protocol. Because they were siblings, the subjects in the study shared family and communicative context. However, they developed different communication abilities, especially regarding the use of oral language. The study showed that the Auditory Neuropathy Spectrum Disorder is a heterogeneous condition in all its aspects, and it is not possible to make generalizations or assume that cases with similar clinical features will develop similar auditory and communicative abilities, even when they are siblings. It is concluded that the acquisition of communicative abilities involves subjective factors, which should be investigated based on the uniqueness of each case.

Dailey, René M; Thompson, Charee M; Romo, Lynsey Kluever

2014-01-01

Although research shows family members can influence each other's diet and exercise behaviors, the specific strategies that most effectively motivate individuals to enact healthy behaviors have not been revealed. Toward this goal, this study employed confirmation theory to assess how the quality of weight management (WM) communication between 107 mother-teen dyads was related to their diet and exercise behaviors as well as their subjective perceptions of the productivity of WM conversations. Confirmation theory proposes two components of confirmation: acceptance and challenge. Analyses revealed that accepting and challenging communication were both positively related to the perceived productivity of WM conversations. However, more complex associations emerged for diet and exercise. Acceptance was more helpful in motivating better eating habits for mothers with low health motivation and teens with high health motivation. For exercise, challenge was helpful in motivating teens with higher sensitivity about communicating about weight issues; however, counter to predictions, challenge was negatively related to exercise for teens with low health motivation and low sensitivity. These interactions, however, explained less variance than analyses for perceived effectiveness and satisfaction.

Consultations with talkative patients present a challenge to doctors. It is difficult to gather all the necessary information within the available time, without damaging the doctor-patient relationship. Based on the listed existing literature and doctors' experiences, we present ten tips for gathering information from talkative patients in an effective manner whilst maintaining a good therapeutic alliance. In consultations with talkative patients, it is important to explore the cause of patients' talkativeness and to adapt one's communication approach accordingly.- Familiar communication strategies such as 'summarizing' can still be applied. When taking this route, a more directive communication approach--e.g. by means of a 'closed-ended summary'--can prevent the patient interrupting the doctor or departing from his subject. There are strategies aimed at avoiding a damaging effect to the doctor-patient relationship when applying this approach: don't be overly directive, make the patient co-responsible for efficient time management in the consultation, and make use of empathic interrupting and humour.

Use of a Recursive-Rule eXtraction algorithm with J48graft to achieve highly accurate and concise rule extraction from a large breast cancer dataset

Directory of Open Access Journals (Sweden)

Yoichi Hayashi

Full Text Available To assist physicians in the diagnosis of breast cancer and thereby improve survival, a highly accurate computer-aided diagnostic system is necessary. Although various machine learning and data mining approaches have been devised to increase diagnostic accuracy, most current methods are inadequate. The recently developed Recursive-Rule eXtraction (Re-RX algorithm provides a hierarchical, recursive consideration of discrete variables prior to analysis of continuous data, and can generate classification rules that have been trained on the basis of both discrete and continuous attributes. The objective of this study was to extract highly accurate, concise, and interpretable classification rules for diagnosis using the Re-RX algorithm with J48graft, a class for generating a grafted C4.5 decision tree. We used the Wisconsin Breast Cancer Dataset (WBCD. Nine research groups provided 10 kinds of highly accurate concrete classification rules for the WBCD. We compared the accuracy and characteristics of the rule set for the WBCD generated using the Re-RX algorithm with J48graft with five rule sets obtained using 10-fold cross validation (CV. We trained the WBCD using the Re-RX algorithm with J48graft and the average classification accuracies of 10 runs of 10-fold CV for the training and test datasets, the number of extracted rules, and the average number of antecedents for the WBCD. Compared with other rule extraction algorithms, the Re-RX algorithm with J48graft resulted in a lower average number of rules for diagnosing breast cancer, which is a substantial advantage. It also provided the lowest average number of antecedents per rule. These features are expected to greatly aid physicians in making accurate and concise diagnoses for patients with breast cancer.

IASMINA PAUNCHICI

2008-05-01

Full Text Available This paper deals with a series of phenomena and forces with a great impact on the value system of the organizational communities. Among the present tendencies, we can especially refer to diversity and growth of the consumers’ demand, the changes that occur in the tastes and preferences of the consumers and the last but not the least important, the great development of information technology. Also, there are other forces that have the same importance, although they only appeared some time later: the development of the communication network, the growth of national and international competition, economy globalization and others. As for the chosen subject, we will deal with different ways in which organizations respond to the present market necessities: communication strategies and promotion techniques for agroalimentary companies. The same as other communication techniques, advertising is used to broadcast messages that can deliver a positive response from the target public. There is a strong resemblance between publicity, on the one hand, and sales promotion, direct marketing, public relations and event communication on the other hand. No matter the method used for transmitting the message, the communication mechanism remains the same. This, and the variety of forms that publicity can take, are the reason why it makes it so difficult to establish distinctive features for publicity. Advertising represents an important component in promotional communication. Having in mind the consumers needs for different foodstuff, that eventually appear on the market, advertising tries to inform, to persuade and to remind consumer regarding its existence. There are many strategies but we can say that in Romania advertising is one of the strongest and very successful techniques in getting known agroalimentary foodstuff.

Friedman, M.H.; Tanner, J.T.

1978-01-01

A program, written in FORTRAN, which defines a language for reducing activation analysis data is described. An attempt was made to optimize the choice of commands and their definitions so as to concisely express what should be done, make the language natural to use and easy to learn, arranqe a system of checks to guard against communication errors and have the language be inclusive. Communications are effected through commands, and these can be given in almost any order. Consistency checks are done and diagnostic messages are printed automatically to guard against the incorrect use of commands. Default options on the commands allow instructions to be expressed concisely while providing a capability to specify details for the data reduction process. The program has been implemented on a UNIVAC 1108 computer. A complete description of the commands, the algorithms used, and the internal consistency checks used are given elsewhere. The applications of the program and the methods for obtaining data automatically have already been described. (T.G.)

Upcoming standard for intervehicle communication IEEE 802.11p, known as Wireless Access in Vehicular Environments (WAVE, is still in its draft stage, but already coming into final standardization phase. Problematic, regarding mobile WAVE nodes, are described in several articles, simulations prepared and experiments done. But most of these works do not consider possible maximal communication load. This paper presents intervehicle communication scenario in respect to radio communications, mobility and other aspects of vehicular environments.Article in English

Facebook – Public Communication Media for the Romanian Institutions

Directory of Open Access Journals (Sweden)

Elena Farcaş

2017-06-01

Full Text Available For the public institutions, social networks represent a communication channel completing what represents the professional public communication, so the role of the professional communicator does not end or diminish and neither does the role of traditional mass-media. It is about an evolution, a modification, an adaptation of public communication and not a replacement of the way of achieving such communication. By this study, I proposed myself to identify the way in which the public institutions in Romania have adapted to the new trends imposed to public communication. To this end, I conducted an analysis of the structure, content, presentation and visibility in the online media of the Facebook pages of the 21 ministries composing the Romanian Government. I chose ministries as a subject of this study because, as institutions representing the central public administration of Romania, they exercise their competence at the level of the entire national territory and, generating public policies, have a major impact on the socio-economic environment, addressing a large number of beneficiaries. I noticed that all the ministries have an official Facebook page, these pages are updated and, by the published information, they are constituted as key elements in all representation media for these institutions.

Type and Behaviour Reconstruction for Higher-Order Concurrent Programs

DEFF Research Database (Denmark)

Amtoft, T.; Nielson, Flemming; Nielson, Hanne Riis

1997-01-01

The authors develop a sound and complete type and behaviour inference algorithm for a fragment of CML (Standard ML with primitives for concurrency). Behaviours resemble terms of a process algebra and yield a concise representation of the communications taking place during execution; types...... are mostly as usual except that function types and `delayed communication types' are labelled by behaviours expressing the communications that will take place if the function is applied or the delayed action is activated. The development of the paper improves a previously published algorithm in achieving...

This study characterized psychiatrist and patient communication behaviors and affective voice tones during pharmacotherapy appointments with depressed patients at four community-based mental health clinics where psychiatrists provided medication management and other mental health professionals provided therapy ("split treatment"). Audiorecordings of 84 unique pairs of psychiatrists and patients with a depressive disorder were analyzed with the Roter Interaction Analysis System, which identifies 41 discrete speech categories that can be grouped into composites representing broad conceptual communication domains. Cluster analysis identified psychiatrist communication patterns. T test and chi square analyses compared the clusters for verbal dominance, affective voice tone, and characteristics of psychiatrist and patients. On average, 53% of psychiatrist talk was devoted to partnering and relationship building, and 67% of patient talk was about biomedical subjects, such as depression symptoms, and psychosocial information giving. Psychiatrist communication patterns were characterized by two clusters, a biomedical-centered cluster that emphasized biomedical questions (η²=.22, df=82, prelationship building while maintaining a focus on symptoms or psychosocial issues. However, patient behaviors did not reflect a similar level of partnering. Future studies should identify psychiatrist communication behaviors that activate collaborative patient communications or improve treatment outcomes.

Shared function knowledge: infants' attention to function information in communicative contexts.

Träuble, Birgit; Bätz, Johannes

Humans are specifically adapted to knowledge acquisition and transfer by social communication. According to natural pedagogy theory, infants are highly sensitive to signals that indicate a teacher's communicative intention and are biased to interpret communicative contexts as conveying relevant and generalizable knowledge that is also shared by other conspecifics. We investigated whether infants as young as 12 months interpret ostensively communicated object-directed emotion expressions as generalizable and shareable with others. Given that young infants pay particular attention to information about objects' functions, we were interested in whether the shareability assumption also holds for emotional attitudes toward functional features of unfamiliar objects. The results suggest that 12-month-olds (N=80) flexibly interpret another person's emotion displays toward unfamiliar artifacts either as object-centered and generalizable attitudes or as person-centered subjective attitudes, depending on the communicative characteristics of the learning context. Furthermore, the transfer of ostensively communicated information about the artifacts depended on their functional usability, which is consistent with infants' early sensitivity to function information in various areas of cognitive development.

Talking about monetary policy: the virtues (and vice?) of central bank communication

OpenAIRE

Alan Blinder

2009-01-01

Central banks, which used to be so secretive, are communicating more and more these days about their monetary policy. This development has proceeded hand in glove with a burgeoning new scholarly literature on the subject. The empirical evidence, reviewed selectively here, suggests that communication can move financial markets, enhance the predictability of monetary policy decisions, and perhaps even help central banks achieve their goals. A number of theoretical drawbacks to greater communica...

Comparison of myocardial 201Tl clearance after maximal and submaximal exercise: implications for diagnosis of coronary disease: concise communication

International Nuclear Information System (INIS)

Recently the quantitation of regional 201 Tl clearance has been shown to increase the sensitivity of the scintigraphic detection of coronary disease. Although 201 Tl clearance rates might be expected to vary with the degree of exercise, this relationship has not been explored. We therefore evaluated the rate of decrease in myocardial 201 Tl activity following maximal and submaximal stress in seven normal subjects and 21 patients with chest pain, using the seven-pinhole tomographic reconstruction technique. In normals, the mean 201 Tl clearance rate declined from 41% +/- 7 over a 3-hr period with maximal exercise to 25% +/- 5 after 3 hr at a submaximal level (p less than 0.001). Similar differences in clearance rates were found in the normally perfused regions of the left ventricle in patients with chest pain, depending on whether or not a maximal end point (defined as either the appearance of ischemia or reaching 85% of age-predicted heart rate) was achieved. In five patients who did not reach these end points, 3-hr clearance rates in uninvolved regions averaged 25% +/- 2, in contrast to a mean of 38% +/- 5 for such regions in 15 patients who exercised to ischemia or an adequate heart rate. These findings indicate that clearance criteria derived from normals can be applied to patients who are stressed maximally, even if the duration of exercise is limited, but that caution must be used in interpreting clearance rates in those who do not exercise to an accepted end point

The dark side of risk and crisis communication: legal conflicts and responsibility allocation

Science.gov (United States)

Scolobig, A.

2015-04-01

Inadequate, misinterpreted or missing risk and crisis communication may be a reason for practitioners, and sometimes even science advisors, to become subjects of criminal charges. This work discusses the legal consequences of communication. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision-making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

Neurodharma Self-Help: Personalized Science Communication as Brain Management.

Over the past ten to fifteen years, medical interventions, therapeutic approaches and scientific studies involving mindfulness meditation have gained traction in areas such as clinical psychology, psychotherapy, and neuroscience. Simultaneously, mindfulness has had a very strong public appeal. This article examines some of the ways in which the medical and scientific meaning of mindfulness is communicated in public and to the public. In particular, it shows how experts in the field of mindfulness neuroscience seek to communicate to the public at large the imperative of brain fitness for the promotion of health, wellbeing and happiness. The study identifies claims being made in popular outlets that, by and large, bypass traditional mass media, such as self-help books, websites and online videos. By treating this material as a form of personalized science communication, this article contributes to the body of literature that understands science communication as a continuum and the boundary between science and popularized science as the outcome of human negotiations. The study finds that processes of personalization help to build bridges between scientific findings and their supposed application, that they infuse science with subjective meaning, and turn expert communication with the public into a moral vocation.

Pro forma: impact on communication skills?

A doctor performs 160 000-300 000 interviews during a lifetime career, thus making the medical interview the most common procedure in clinical medicine. It is reported that 60-80 per cent of diagnosis is based on history taking, yet there is little published data advising on the best method for medical students to initially attain and further refine these core skills during their medical degree. Medical students interviewed two patients: using an open interview first, based on the Calgary-Cambridge approach, and then using a structured pro forma. The students' medical data were assessed by a senior lecturer, and their communication skills were assessed by a behavioural scientist and by the patients. An exact Wilcoxon paired signed rank test was conducted to determine whether there was a difference between the open interview and pro forma methods for history taking and communication skills. The test yielded p-values of 0.0017 and 0.069, respectively, with the pro forma method providing a statistically significantly higher history-taking score and communication score than the open interview method. Subjectively, patients reported the pro forma method as being preferable. Medical students in the early years of training benefit from a structured history-taking pro forma to assist them gather an accurate data set without compromising their interpersonal and communication skills. © 2013 John Wiley & Sons Ltd.

Studies in interactive communication. I - The effects of four communication modes on the behavior of teams during cooperative problem-solving.

Two-man teams solved credible, 'real-world' problems for which computer assistance has been or could be useful. Conversations were carried on in one of four modes of communication: (1) typewriting, (2) handwriting, (3) voice, and (4) natural, unrestricted communication. Two groups of subjects (experienced and inexperienced typists) were tested in the typewriting mode. Performance was assessed on three classes of dependent measures: time to solution, behavioral measures of activity, and linguistic measures. Significant and meaningful differences among the communication modes were found in each of the three classes of dependent variable. This paper is concerned mainly with the results of the activity analyses. Behavior was recorded in 15 different categories. The analyses of variance yielded 34 statistically significant terms of which 27 were judged to be practically significant as well. When the data were transformed to eliminate heterogeneity, the analyses of variance yielded 35 statistically significant terms of which 26 were judged to be practically significant.

A concise treatise on quantum mechanics in phase space

CERN Document Server

Curtright, Thomas L; Zachos, Cosmas K

2014-01-01

This is a text on quantum mechanics formulated simultaneously in terms of position and momentum, i.e. in phase space. It is written at an introductory level, drawing on the remarkable history of the subject for inspiration and motivation. Wigner functions density -- matrices in a special Weyl representation -- and star products are the cornerstones of the formalism. The resulting framework is a rich source of physical intuition. It has been used to describe transport in quantum optics, structure and dynamics in nuclear physics, chaos, and decoherence in quantum computing. It is also of importance in signal processing and the mathematics of algebraic deformation. A remarkable aspect of its internal logic, pioneered by Groenewold and Moyal, has only emerged in the last quarter-century: it furnishes a third, alternative way to formulate and understand quantum mechanics, independent of the conventional Hilbert space or path integral approaches to the subject. In this logically complete and self-standing formula...
