    In this paper, we present a schema for content-based analysis of broadcast news video. First, we separate commercials from news using audiovisual features. Then, we automatically organize news programs into a content hierarchy at various levels of abstraction via effective integration of video, audio, and text data available from the news programs. Based on these news video structure and content analysis technologies, a TV news video Library is generated, from which users can retrieve definite news story according to their demands.

  2. The U.S. Online News Coverage of Mammography Based on a Google News Search.

    To characterize online news coverage relating to mammography, including articles' stance toward screening mammography. Google News was used to search U.S. news sites over a 9-year period (2006-2015) based on the search terms "mammography" and "mammogram." The top 100 search results were recorded. Identified articles were manually reviewed. The top 100 news articles were from the following sources: local news outlet (50%), national news outlet (24%), nonimaging medical source (13%), entertainment or culture news outlet (6%), business news outlet (4%), peer-reviewed journal (1%), and radiology news outlet (1%). Most common major themes were the screening mammography controversy (29%), description of a new breast imaging technology (23%), dense breasts (11%), and promotion of a public screening initiative (11%). For the most recent year, article stance toward screening mammography was 59%, favorable; 16%, unfavorable; and 25%, neutral. After 2010, there was an abrupt shift in articles' stances from neutral to both favorable and unfavorable. A wide range of online news sources addressed a range of issues related to mammography. National, rather than local, news sites were more likely to focus on the screening controversy and more likely to take an unfavorable view. The controversial United States Preventive Services Task Force guidelines may have influenced articles to take a stance on screening mammography. As such online news may impact public perception of the topic and thus potentially impact guideline adherence, radiologists are encouraged to maintain awareness of this online coverage and to support the online dissemination of reliable and accurate information.

    2005-09-01

    A brief history is given of approaches that aim at achieving a connectedness of the content of organic chemistry courses to real world issues. Recently, such approaches have relied more and more on online media resources, the tools of the Internet and the World Wide Web. We propose a six-level taxonomy of ‘authentic news media-based learning activities’ to provide a conceptual framework for the description and discussion of such approaches. The Chemistry Is in the News project was designed to allow students to draw explicit connections between the course content and real world issues in ways that engage the students in a full range of cognitive skills. The activities consisted in the study, creation, and peer review of news portfolios by student collaborative groups. A news portfolio consists of an authentic news article taken from the popular press with interpretive comments and questions.

    2014-01-01

    The most current news recommendations are suitable for news which comes from a single news website, not for news from different heterogeneous news websites. Previous researches about news recommender systems based on different strategies have been proposed to provide news personalization services for online news readers. However, little research work has been reported on utilizing hundreds of heterogeneous news websites to provide top hot news services for group customers (e.g., government staffs). In this paper, we propose a hot news recommendation model based on Bayesian model, which is from hundreds of different news websites. In the model, we determine whether the news is hot news by calculating the joint probability of the news. We evaluate and compare our proposed recommendation model with the results of human experts on the real data sets. Experimental results demonstrate the reliability and effectiveness of our method. We also implement this model in hot news recommendation system of Hangzhou city government in year 2013, which achieves very good results. PMID:25093207

    2007-11-01

    Overlaid caption in news video often carries condensed semantic information which is key cues for content-based video indexing and retrieval. However, it is still a challenging work to extract caption from video because of its complex background and low resolution. In this paper, we propose an effective overlaid caption extraction approach for news video. We first scan the video key frames using a small window, and then classify the blocks into the text and non-text ones via support vector machine (SVM), with statistical features extracted from the gray level co-occurrence matrices, the LH and HL sub-bands wavelet coefficients and the orientated edge intensity ratios. Finally morphological filtering and projection profile analysis are employed to localize and refine the candidate caption regions. Experiments show its high performance on four 30-minute news video programs.

  14. Texting while driving: is speech-based text entry less risky than handheld text entry?

    Research indicates that using a cell phone to talk or text while maneuvering a vehicle impairs driving performance. However, few published studies directly compare the distracting effects of texting using a hands-free (i.e., speech-based interface) versus handheld cell phone, which is an important issue for legislation, automotive interface design and driving safety training. This study compared the effect of speech-based versus handheld text entries on simulated driving performance by asking participants to perform a car following task while controlling the duration of a secondary text-entry task. Results showed that both speech-based and handheld text entries impaired driving performance relative to the drive-only condition by causing more variation in speed and lane position. Handheld text entry also increased the brake response time and increased variation in headway distance. Text entry using a speech-based cell phone was less detrimental to driving performance than handheld text entry. Nevertheless, the speech-based text entry task still significantly impaired driving compared to the drive-only condition. These results suggest that speech-based text entry disrupts driving, but reduces the level of performance interference compared to text entry with a handheld device. In addition, the difference in the distraction effect caused by speech-based and handheld text entry is not simply due to the difference in task duration. Copyright © 2014 Elsevier Ltd.

  16. ['Walkability' and physical activity - results of empirical studies based on the 'Neighbourhood Environment Walkability Scale (NEWS)'].

    PubMed

    Rottmann, M; Mielck, A

    2014-02-01

    'Walkability' is mainly assessed by the NEWS questionnaire (Neighbourhood Environment Walkability Scale); in Germany this questionnaire is widely unknown. We now try to fill this gap by providing a systematic overview of empirical studies based on the NEWS. A systematic review was conducted concerning original papers including empirical analyses based on the NEWS. The results are summarised and presented in tables. Altogether 31 publications could be identified. Most of them focus on associations with the variable 'physical activity', and they often report significant associations with at least some of the scales included in the NEWS. Due to methodological differences between the studies it is difficult to compare the results. The concept of 'walkability' should also be established in the German public health discussion. A number of methodological challenges remain to be solved, such as the identification of those scales and items in the NEWS that show the strongest associations with individual health behaviours. © Georg Thieme Verlag KG Stuttgart · New York.

    2001-12-01

    TV News is a well-structured media, since it has distinct boundaries of semantic units (news stories) and relatively constant content structure. Hence, an efficient algorithm to segment and analyze the structure information among news videos would be necessary for indexing or retrieving a large video database. Lots of researches in this area have been done by using close-caption, speech recognition or Video-OCR to obtain the semantic content, however, these methods put much emphasis on obtaining the text and NLP for semantic understanding. Here, in this paper, we try to solve the problem by integrating statistic model and visual features. First, a video caption and anchorperson shot detection method is presented, after that, a statistic model is used to describe the relationship between the captions and the news story boundaries, then, a news story segmentation method is introduced by integrating all these aforementioned results. The experiment results have proved that the method can be used in acquiring most of the structure information in News programs.

    A new research effort at NASA Ames Research Center has been initiated in Planetary Defense, which integrates the disciplines of planetary science, atmospheric entry physics, and physics-based risk assessment. This paper describes work within the new program and is focused on meteor entry and breakup. Over the last six decades significant effort was expended in the US and in Europe to understand meteor entry including ablation, fragmentation and airburst (if any) for various types of meteors ranging from stony to iron spectral types. These efforts have produced primarily empirical mathematical models based on observations. Weaknesses of these models, apart from their empiricism, are reliance on idealized shapes (spheres, cylinders, etc.) and simplified models for thermal response of meteoritic materials to aerodynamic and radiative heating. Furthermore, the fragmentation and energy release of meteors (airburst) is poorly understood. On the other hand, flight of human-made atmospheric entry capsules is well understood. The capsules and their requisite heat shields are designed and margined to survive entry. However, the highest speed Earth entry for capsules is 13 kms (Stardust). Furthermore, Earth entry capsules have never exceeded diameters of 5 m, nor have their peak aerothermal environments exceeded 0.3 atm and 1 kWcm2. The aims of the current work are: (i) to define the aerothermal environments for objects with entry velocities from 13 to 20 kms; (ii) to explore various hypotheses of fragmentation and airburst of stony meteors in the near term; (iii) to explore the possibility of performing relevant ground-based tests to verify candidate hypotheses; and (iv) to quantify the energy released in airbursts. The results of the new simulations will be used to anchor said risk assessment analyses.With these aims in mind, state-of-the-art entry capsule design tools are being extended for meteor entries.

    2017-03-01

    The portrayal of child autism-related news stories has become a serious issue in the United States, yet few studies address this from media framing perspective. To fill this gap in the literature, this study examined the applicability of a media framing scale (Semetko & Valkenburg, 2000) for the deductive examination of autism-related news stories in U.S.-based newspapers. Under the theoretical framework of framing theory, a content analysis of news stories (N = 413) was conducted to investigate the presence of the five news frames using an established questionnaire. Differentiating between local and national news outlets, the following five news frames were measured: (a) attribution of responsibility, (b) human interest, (c) conflict, (d) morality, and (e) economic consequences. Findings revealed that news stories about autism most frequently fell within the human interest frame. Furthermore, the study shed light on how local and national newspapers might differ in framing autism-related news pieces and in their placement of the autism-related story within the newspaper (e.g., front page section, community section).

    This communication is to announce the availability of a network server for biological sequence database entries which will allow scientists to fetch entries in a desired format directly into their file store. This server will use TCP/IP protocols allowing any user with an Internet connection to participate. FarFetch will allow users to obtain sequence entries in a directly usable form as opposed to conventional e-mail based sequence retrievers. This server also differs from Gopher and WAIS servers in that the sequence entry is written into the user's file store in a format that is immediately usable. Clients for the OpenVMS, Unix and Macintosh operating systems have been written and are available via anonymous ftp. Development of MS-DOS and Windows clients is planned. There will be no usage fees associated with the server.

    2017-10-01

    A diagnosis of cancer is a stressful, difficult, and life-altering event. Breaking bad news is distressing to patients and families and is often uncomfortable for the nurse delivering it. Evidence-based communication models have been developed and adapted for use in clinical practice to assist nurses with breaking bad news.

. The purpose of this article is to provide an overview on breaking bad news and to review the utility of the SPIKES and PEWTER evidence-based communication models for oncology nurses.
. Perceptions of breaking bad news from the nurse and patient perspectives, as well as barriers and consequences to effective communication, will be presented. Clinical examples of possible situations of breaking bad news will demonstrate how to use the SPIKES and PEWTER models of communication when disclosing bad news to patients and their families.
. By using the evidence-based communication strategies depicted in this article, oncology nurses can support the delivery of bad news and maintain communication with their patients and their patients' families in an effective and productive manner.

    The availability of GPS observations via the telemetry during GOCE’s (Gravity Field and Steady-State Ocean Circulation Explorer) entire re-entry campaign enabled the generation of high quality orbit products which can be used as input to re-entry predictions. These high precision orbits can be used as reference to assess the quality of orbits generated from other sources. Here we verify the accuracy of orbits based on radar tracking data, obtained by dedicated observations with the Tracking & Imaging Radar system from the Fraunhofer High Frequency Physics and Radar Techniques institute, with respect to the a post-processed GPS based reference orbit. This leads to time-depended quantification of the orbit determination uncertainties on the re-entry predictions. Furthermore, the ballistic coefficient determined by the orbit determination and its time dependent evolution can be used to a priori estimate the attitude behaviour of GOCE, which can be compared to the telemetry. The attitude behaviour can be analysed by the use of inverse synthetic aperture radar (ISAR) images, also obtained by dedicated observation by TIRA. The effect of adding this knowledge on the attitude evolution to the re-entry predictions is evaluated.

    Computer-based physician order entry (CPOE) is a key feature of electronic health record systems. A fully-featured CPOE system, capable of dealing with drug prescription, but also with all the other aspects of patients care, can be used to implement standardized clinical pathways. This classic design can be improved upon by using a workflow engine to drive and bring together the different tasks incorporated in a pathway, including clinical documentation.

    A first order simulation analysis of the navigation accuracy expected from various Navigation Quick-Look data sets is performed. Here quick-look navigation data are observations obtained by hypothetical telemetried data transmitted on the fly during a Mars probe's atmospheric entry. In this simulation study, navigation data consists of 3-axis accelerometer sensor and attitude information data. Three entry vehicle guidance types are studied: I. a Maneuvering entry vehicle (as with Mars 01 guidance where angle of attack and bank angle are controlled); II. Zero angle-of-attack controlled entry vehicle (as with Mars 98); and III. Ballistic, or spin stabilized entry vehicle (as with Mars Pathfinder);. For each type, sensitivity to progressively under sampled navigation data and inclusion of sensor errors are characterized. Attempts to mitigate the reconstructed trajectory errors, including smoothing, interpolation and changing integrator characteristics are also studied.

  9. Mars entry guidance based on an adaptive reference drag profile

    2017-08-01

    The conventional Mars entry tracks a fixed reference drag profile (FRDP). To improve the landing precision, a novel guidance approach that utilizes an adaptive reference drag profile (ARDP) is presented. The entry flight is divided into two phases. For each phase, a family of drag profiles corresponding to various trajectory lengths is planned. Two update windows are investigated for the reference drag profile. At each window, the ARDP is selected online from the profile database according to the actual range-to-go. The tracking law for the selected drag profile is designed based on the feedback linearization. Guidance approaches using the ARDP and the FRDP are then tested and compared. Simulation results demonstrate that the proposed ARDP approach achieves much higher guidance precision than the conventional FRDP approach.

    In this paper, we present our work for automatic generation of textual metadata based on visual content analysis of video news. We present two methods for semantic object detection and recognition from a cross modal image-text thesaurus. These thesaurus represent a supervised association between models and semantic labels. This paper is concerned with two semantic objects: faces and Tv logos. In the first part, we present our work for efficient face detection and recogniton with automatic name generation. This method allows us also to suggest the textual annotation of shots close-up estimation. On the other hand, we were interested to automatically detect and recognize different Tv logos present on incoming different news from different Tv Channels. This work was done jointly with the French Tv Channel TF1 within the "MediaWorks" project that consists on an hybrid text-image indexing and retrieval plateform for video news.

  11. Physics-based Entry, Descent and Landing Risk Model

    Gee, Ken; Huynh, Loc C.; Manning, Ted

    2014-01-01

    A physics-based risk model was developed to assess the risk associated with thermal protection system failures during the entry, descent and landing phase of a manned spacecraft mission. In the model, entry trajectories were computed using a three-degree-of-freedom trajectory tool, the aerothermodynamic heating environment was computed using an engineering-level computational tool and the thermal response of the TPS material was modeled using a one-dimensional thermal response tool. The model was capable of modeling the effect of micrometeoroid and orbital debris impact damage on the TPS thermal response. A Monte Carlo analysis was used to determine the effects of uncertainties in the vehicle state at Entry Interface, aerothermodynamic heating and material properties on the performance of the TPS design. The failure criterion was set as a temperature limit at the bondline between the TPS and the underlying structure. Both direct computation and response surface approaches were used to compute the risk. The model was applied to a generic manned space capsule design. The effect of material property uncertainty and MMOD damage on risk of failure were analyzed. A comparison of the direct computation and response surface approach was undertaken.

    Lacovara, R. C.

    1986-01-01

    The entry of graphical engineering data into the Space Station Data Base was examined. Discussed were: representation of graphics objects; representation of connectivity data; graphics capture hardware; graphics display hardware; site-wide distribution of graphics, and consolidation of tools and hardware. A fundamental assumption was that existing equipment such as IBM based graphics capture software and VAX networked facilities would be exploited. Defensible conclusions reached after study and simulations of use of these systems at the engineering level are: (1) existing IBM based graphics capture software is an adequate and economical means of entry of schematic and block diagram data for present and anticipated electronic systems for Space Station; (2) connectivity data from the aforementioned system may be incorporated into the envisioned Space Station Data Base with modest effort; (3) graphics and connectivity data captured on the IBM based system may be exported to the VAX network in a simple and direct fashion; (4) graphics data may be displayed site-wide on VT-125 terminals and lookalikes; (5) graphics hard-copy may be produced site-wide on various dot-matrix printers; and (6) the system may provide integrated engineering services at both the engineering and engineering management level.

  19. Critical Reading of Science-Based News Reports: Establishing a knowledge, skills and attitudes framework

    NASA Astrophysics Data System (ADS)

    McClune, Billy; Jarman, Ruth

    2010-04-01

    A recognised aim of science education is to promote critical engagement with science in the media. Evidence would suggest that this is challenging for both teachers and pupils and that science education does not yet adequately prepare young people for this task. Furthermore, in the absence of clear guidance as to what this means and how this may be achieved it is difficult for teachers to develop approaches and resources that address the matter and that systematically promote such critical engagement within their teaching programmes. Twenty-six individuals with recognised expertise or interest in science in the media, drawn from a range of disciplines and areas of practice, constituted a specialist panel in this study. The question this research sought to answer was "what are the elements of knowledge, skill, and attitude which underpin critical reading of science-based news reports?" During in-depth individual interviews the panel were asked to explore what they considered to be essential elements of knowledge, skills, and attitude which people need to enable them to respond critically to news reports with a science component. Analysis of the data revealed 14 fundamental elements which together contribute to an individual's capacity to engage critically with science-based news. These are classified in five categories "knowledge of science", "knowledge of writing and language", "knowledge about news, newspapers and journalism", "skills", and "attitudes". Illustrative profiles of each category along with indicators of critical engagement are presented. The implications for curriculum planning and pedagogy are considered.

    Physics of atmospheric entry of meteoroids was an active area of research at NASA ARC up to the early 1970s (e.g., the oft-cited work of Baldwin and Sheaffer). However, research in the area seems to have ended with the Apollo program, and any ties with an active international meteor physics community seem to have significantly diminished thereafter. In the decades following the 1970s, the focus of entry physics at NASA ARC has been on improvement of the math models of shock-layer physics (especially in chemical kinetics and radiation) and thermal response of ablative materials used for capsule heatshields. With the overarching objectives of understanding energy deposition into the atmosphere and fragmentation, could these modern analysis tools and processes be applied to the problem of atmospheric entry of meteoroids as well? In the presentation we will explore: (i) the physics of atmospheric entries of meteoroids using our current state-of-the-art tools and processes, (ii) the influence of shape (and shape change) on flow characteristics, and (iii) how multiple bodies interact.

  3. Media Representations of Breech Birth: A Prospective Analysis of Web-Based News Reports.

    PubMed

    Petrovska, Karolina; Sheehan, Athena; Homer, Caroline S E

    2017-07-01

    Recent research has demonstrated that the media presentation of childbirth is highly medicalized, often portraying birth as risky and dramatic. Media representation of breech presentation and birth is unexplored in this context. This study aimed to explore the content and tone of news media reports relating to breech presentation and breech birth. Google alerts were created using the terms breech and breech birth in online English-language news sites over a 3-year period from January 1, 2013, to December 31, 2015. Alerts were received daily and filed for analysis, and data were analyzed to generate themes. A total of 138 web-based news reports were gathered from 9 countries. Five themes that arose from the data included the problem of breech presentation, the high drama of vaginal breech birth, the safe option of cesarean birth versus dangers of vaginal breech birth, the defiant mother versus the saintly mother, and vaginal breech birth and medical misadventure. Media reports in this study predominantly demonstrated negative views toward breech presentation and vaginal breech birth. Cesarean birth was portrayed as the safe option for breech birth, while vaginal breech birth was associated with poor outcomes. Media presentations may impact decision making about mode of birth for pregnant women with a breech fetus. Health care providers can play an important role in balancing the media depiction of planned vaginal breech birth by providing nonjudgmental, evidence-based information to such women to facilitate informed decision making for birth. © 2017 by the American College of Nurse-Midwives.

    Casciotti, Dana; Smith, Katherine C.; Andon, Lindsay; Vernick, Jon; Tsui, Amy; Klassen, Ann C.

    2015-01-01

    BACKGROUND In 2007, legislation was proposed in 24 states and the District of Columbia for school-based HPV vaccine mandates, and mandates were enacted in Texas, Virginia, and the District of Columbia. Media coverage of these events was extensive, and media messages both reflected and contributed to controversy surrounding these legislative activities. Messages communicated through the media are an important influence on adolescent and parent understanding of school-based vaccine mandates. METHODS We conducted structured text analysis of newspaper coverage, including quantitative analysis of 169 articles published in mandate jurisdictions from 2005-2009, and qualitative analysis of 63 articles from 2007. Our structured analysis identified topics, key stakeholders and sources, tone, and the presence of conflict. Qualitative thematic analysis identified key messages and issues. RESULTS Media coverage was often incomplete, providing little context about cervical cancer or screening. Skepticism and autonomy concerns were common. Messages reflected conflict and distrust of government activities, which could negatively impact this and other youth-focused public health initiatives. CONCLUSIONS If school health professionals are aware of the potential issues raised in media coverage of school-based health mandates, they will be more able to convey appropriate health education messages, and promote informed decision-making by parents and students.

  5. Orion Entry Performance-Based Center-of-Gravity Box

    NASA Technical Reports Server (NTRS)

    Rea, Jeremy R.

    2010-01-01

    The Orion capsule has many performance requirements for its atmospheric entry trajectory. Requirements on landing accuracy, maximum heating rate, total heat load, propellant usage, and sensed acceleration must all be satised. It is desired to define a methodology to translate the many performance requirements for an atmospheric entry trajectory into language easily understood by vehicle designers in terms of an allowable center-of-gravity box. This is possible by noting that most entry performance parameters for a capsule vehicle are mainly determined by the lift-to-drag ratio of the vehicle. However, the lift-to- drag ratio should be considered a probabilistic quantity rather than deterministic, where variations in the lift-to-drag are caused by both aerodynamic and center-of-gravity un- certainties. This paper discusses the technique used by the Orion program to define the allowable dispersions in center-of-gravity to achieve the desired entry performance while accounting for aerodynamic uncertainty.

    2009-11-01

    The implementation of a home-based order-entry program at a community hospital is described. Parkview Hospital is a 600-bed, community-based facility located in Fort Wayne, Indiana, that provides 24-hour pharmacy services. The main purpose for establishing a home-based order-entry program was to provide extra pharmacist coverage during the event of a spontaneous order surge in an effort to maintain excellent customer service. A virtual private network (VPN) was created to ensure the security and confidentiality of patients' health care information. The names of volunteer pharmacists who met specific criteria and who were capable of performing home-based order entry were collected. These pharmacists were trained and tested in the home-based order-entry process. When home-based order-entry is needed, the lead pharmacist contacts the pharmacists on the list by telephone. If available, the pharmacists (maximum of three) are notified to log into the Internet, access the VPN, and perform order entry with the same vigilance, confidentiality, and care as they would onsite. Home-based order entry is discontinued when off-trigger points are met. Pharmacists entering orders from home are paid by the time spent conducting order entry. Pharmacists reported that the program was easy to contact home-based order-entry volunteers, there were no problems with logging into the VPNs, and turnaround time was close to our target of 25 minutes. A community-based hospital successfully implemented a home-based medication order-entry program. The program alleviated the shortage of pharmacists during spontaneous surges of medication orders.

  12. Orion Entry Performance-Based Center-of-Gravity Box

    NASA Technical Reports Server (NTRS)

    Rea, Jeremy R.

    2010-01-01

    The Orion capsule is designed both for Low Earth Orbit missions to the ISS and for missions to the moon. For ISS class missions, the capsule will use an Apollo-style direct entry. For lunar return missions, depending on the timing of the mission, the capsule could perform a direct entry or a skip entry of up to 4800 n.mi. in order to land in the coastal waters of California. The physics of atmospheric re-entry determine the capability of the Orion vehicle. For a given vehicle mass and shape, physics tells us that the driving parameters for an entry vehicle are the hypersonic lift-to-drag ratio (L/D) and the flight path angle at entry interface (gamma(sub EI)). The design of the Orion atmospheric re-entry must meet constraints during both nominal and dispersed flight conditions on landing accuracy, heating rate, total heat load, sensed acceleration, and proper disposal of the Service Module. These constraints define an entry corridor in the space of L/D-gamma(sub EI); if the vehicle falls within this corridor, then all constraints are met. The gamma(sub EI) dimension of the corridor can be further constrained by the gloads experienced during emergency entries. Thus, the entry performance for the Orion vehicle can be described completely by the L/D. Bounds on the hypersonic L/D necessary to achieve all the mission requirements can be defined for the given entry corridor. Landing accuracy performance drives the lower limit on L/D. In order to achieve the desired landing accuracy, a minimum L/D must be ensured. The design of the Thermal Protection System (TPS) drives the upper limit on L/D. A higher L/D can drive mass into the design of the TPS. Conversely, once the TPS is designed, the L/D must be ensured to stay below a certain limit in order for the TPS to stay within its design envelop. The L/D must stay within its upper and lower bounds during dispersed flight conditions. L/D is a function of both the aerodynamics and the center-of-gravity (CG) of the vehicle. The

  13. Are we there yet? The state of the evidence base for guidelines on breaking bad news to cancer patients.

    The way clinicians break bad news to cancer patients has been retrospectively associated with poor psychosocial outcomes for patients. Education and practice in breaking bad news may be ineffective for improving patients' well-being unless it is informed by a sound evidence base. In the health field, research efforts are expected to advance evidence over time to inform evidence-based practice. Key characteristics of an advancing evidence base are a predominance of new data, and rigorous intervention studies which prospectively demonstrate improved outcomes. This review aimed to examine the progress of the evidence base in breaking bad news to cancer patients. Manual and computer-based searches (Medline and PsycINFO) were performed to identify publications on the topic of breaking bad news to cancer patients published between January 1995 and March 2009. Relevant publications were coded in terms of whether they provided new data, examined psychosocial outcomes for patients or tested intervention strategies and whether intervention studies met criteria for design rigour. Of the 245 relevant publications, 55.5% provided new data and 16.7% were intervention studies. Much of the intervention effort was directed towards improving provider skills rather than patient outcomes (9.8% of studies). Less than 2% of publications were rigorous intervention studies which addressed psychosocial outcomes for patients. Rigorous intervention studies which evaluate strategies for improving psychosocial outcomes in relation to breaking bad news to cancer patients are needed. Current practice and training regarding breaking bad news cannot be regarded as evidence-based until further research is completed.

  14. Assisted entry mitigates text messaging-based driving detriment.

    PubMed

    Sawyer, Benjamin D; Hancock, Peter A

    2012-01-01

    Previous research using cell phones indicates that manual manipulation is not a principal component of text messaging relating driving detriment. This paper suggests that manipulation of a phone in conjunction with the cognitive need to compose the message itself co-act to contribute to driving degradation. This being so, drivers sending text messages might experience reduced interference to the driving task if the text messaging itself were assisted through the predictive T9 system. We evaluated undergraduate drivers in a simulator who drove and texted using either Assisted Text entry, via Nokia's T9 system, or unassisted entry via the multitap interface. Results supported the superiority of the T9 system over the multitap system implying that specific assistive technologies can modulate the degradation of capacity which texting tragically induces.

  15. Design of a Template for Handwriting Based Hindi Text Entry in Handheld Devices

    NASA Astrophysics Data System (ADS)

    Gangopadhyay, Diya; Vasal, Ityam; Yammiyavar, Pradeep

    Mobile phones, in the recent times, have become affordable and accessible to a wider range of users including the hitherto technologically and economically under-represented segments. Indian users are a gigantic consumer base for mobile phones. With Hindi being one of the most widely spoken languages in the country and the primary tool of communication for about a third of its population, an effective solution for Hindi text entry in mobile devices is expected to be immensely useful to the non English speaking users. This paper proposes a mobile phone handwriting based text entry solution for Hindi language, which allows for an easy text entry method, while facilitating better recognition accuracy.

    Fox, Jane

    This article presents findings from an 18-month case study of a web-based news group used by individuals with alopecia universalis. Content analysis of 228 episodes of web-based communication that occurred in relation to themes of discussion was undertaken, supported by the use of concept mapping (Northcott, 1996). Analysis identified a core concept relating to that of a community of shared experience together with four supportive themes. The themes were the search for understanding and meaning, carrying on, seeking balance between past, present and future, and relating to new self, others, and the world. The article discusses the increased growth in the use of the web as a vehicle for exploring health concerns and the specific ethical and methodological issues raised by research in this area.

    1999-08-01

    Personal News Retrieval System is a client-server application that delivers news segments on demand in a variety of information networks. At the server side, the news stories are segmented out from the digitized TV broadcast then classified and filtered based on consumers' preferences. At the client side, the user can access the preferred video news through the Web and watch stored video news in preferred order. Browsing preferences can be set based on anchorperson, broadcaster, category, location, top- stories and keywords. This system can be used to set up a news service run by content providers or independent media distribution companies. However, in the news era of enhanced PC/TV appliances, it is foreseeable that the whole system can run in the living room on a personal device. This paper describes the chosen server architecture, limitation of the system and solutions that can be implemented in the future.

The objective of this paper is to analyze the perception of residents regarding a training program in communicating bad news in perinatology based on video reviews and setting, perception, invitation, knowledge, emotion, and summary (SPIKES) strategy. Methods We performed the analysis of complementary data collected from participants in a randomized controlled intervention study to evaluate the efficacy of a training program on improving residents' skills to communicate bad news. Data were collected using a Likert scale. Through a thematic content analysis we tried to to apprehend the meanings, feelings and experiences expressed by resident doctors in their comments as a response to an open-ended question. Half of the group received training, consisting of discussions of video reviews of participants' simulated encounters communicating a perinatal loss to a "mother" based on the SPIKES strategy. We also offered training sessions to the control group after they completed participation. Twenty-eight residents who were randomized to intervention and 16 from the control group received training. Twenty written comments were analyzed. Results The majority of the residents evaluated training highly as an education activity to help increase knowledge, ability and understanding about breaking bad news in perinatology. Three big categories emerged from residents' comments: SPIKES training effects; bad news communication in medical training; and doctors' feelings and relationship with patients. Conclusions Residents took SPIKES training as a guide to systematize the communication of bad news and to amplify perceptions of the emotional needs of the patients. They suggested the insertion of a similar training in their residency programs curricula. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.

    This Account provides an overview of a multidisciplinary consortium focused on structure-based strategies to devise small molecule antagonists of HIV-1 entry into human T-cells, which if successful would hold considerable promise for the development of prophylactic modalities to prevent HIV transmission and thereby alter the course of the AIDS pandemic. Entry of the human immunodeficiency virus (HIV) into target T-cells entails an interaction between CD4 on the host T-cell and gp120, a component of the trimeric envelope glycoprotein spike on the virion surface. The resultant interaction initiates a series of conformational changes within the envelope spike that permits binding to a chemokine receptor, formation of the gp41 fusion complex, and cell entry. A hydrophobic cavity at the CD4-gp120 interface, defined by X-ray crystallography, provided an initial site for small molecule antagonist design. This site however has evolved to facilitate viral entry. As such, the binding of prospective small molecule inhibitors within this gp120 cavity can inadvertently trigger an allosteric entry signal. Structural characterization of the CD4-gp120 interface, which provided the foundation for small molecule structure-based inhibitor design, will be presented first. An integrated approach combining biochemical, virological, structural, computational, and synthetic studies, along with a detailed analysis of ligand binding energetics, revealed that modestly active small molecule inhibitors of HIV entry can also promote viral entry into cells lacking the CD4 receptor protein; these competitive inhibitors were termed small molecule CD4 mimetics. Related congeners were subsequently identified with both improved binding affinity and more potent viral entry inhibition. Further assessment of the affinity-enhanced small molecule CD4 mimetics demonstrated that premature initiation of conformational change within the viral envelope spike, prior to cell encounter, can lead to irreversible

    The diffusion of breaking news largely relies on propagation behaviors in the media. The tremendous and intricate propagation relationships in the media form a complex network. An improved understanding of breaking news diffusion characteristics can be obtained through the complex network research. Drawing on the news data of Bohai Gulf oil spill event from June 2011 to May 2014, we constructed a weighted and directed complex network in which media are set as nodes, the propagation relationships as edges and the propagation times as the weight of the edges. The primary results show (1) the propagation network presents small world feature, which means relations among media are close and breaking news originating from any node can spread rapidly; (2) traditional media and official websites are the typical sources for news propagation, while business portals are news collectors and spreaders; (3) the propagation network is assortative and the group of core media facilities the spread of breaking news faster; (4) for online media, news originality factor become less important to propagation behaviors. This study offers a new insight to explore information dissemination from the perspective of statistical physics and is beneficial for utilizing the public opinion in a positive way.

    2012-01-01

    Background The clinical and scientific usage of patient-reported outcome measures is increasing in the health services. Often paper forms are used. Manual double entry of data is defined as the definitive gold standard for transferring data to an electronic format, but the process is laborious. Automated forms processing may be an alternative, but further validation is warranted. Methods 200 patients were randomly selected from a cohort of 5777 patients who had previously answered two different questionnaires. The questionnaires were scanned using an automated forms processing technique, as well as processed by single and double manual data entry, using the EpiData Entry data entry program. The main outcome measure was the proportion of correctly entered numbers at question, form and study level. Results Manual double-key data entry (error proportion per 1000 fields = 0.046 (95% CI: 0.001–0.258)) performed better than single-key data entry (error proportion per 1000 fields = 0.370 (95% CI: 0.160–0.729), (p = 0.020)). There was no statistical difference between Optical Mark Recognition (error proportion per 1000 fields = 0.046 (95% CI: 0.001–0.258)) and double-key data entry (p = 1.000). With the Intelligent Character Recognition method, there was no statistical difference compared to single-key data entry (error proportion per 1000 fields = 6.734 (95% CI: 0.817–24.113), (p = 0.656)), as well as double-key data entry (error proportion per 1000 fields = 3.367 (95% CI: 0.085–18.616)), (p = 0.319)). Conclusions Automated forms processing is a valid alternative to double manual data entry for highly structured forms containing only check boxes, numerical codes and no dates. Automated forms processing can be superior to single manual data entry through a data entry program, depending on the method chosen. PMID:22493733

    Introduction Tight glycemic control (TGC) has shown benefits but has been difficult to achieve consistently. Model-based methods and computerized protocols offer the opportunity to improve TGC quality but require human data entry, particularly of blood glucose (BG) values, which can be significantly prone to error. This study presents the design and optimization of data entry methods to minimize error for a computerized and model-based TGC method prior to pilot clinical trials. Method To minimize data entry error, two tests were carried out to optimize a method with errors less than the 5%-plus reported in other studies. Four initial methods were tested on 40 subjects in random order, and the best two were tested more rigorously on 34 subjects. The tests measured entry speed and accuracy. Errors were reported as corrected and uncorrected errors, with the sum comprising a total error rate. The first set of tests used randomly selected values, while the second set used the same values for all subjects to allow comparisons across users and direct assessment of the magnitude of errors. These research tests were approved by the University of Canterbury Ethics Committee. Results The final data entry method tested reduced errors to less than 1–2%, a 60–80% reduction from reported values. The magnitude of errors was clinically significant and was typically by 10.0 mmol/liter or an order of magnitude but only for extreme values of BG < 2.0 mmol/liter or BG > 15.0–20.0 mmol/liter, both of which could be easily corrected with automated checking of extreme values for safety. Conclusions The data entry method selected significantly reduced data entry errors in the limited design tests presented, and is in use on a clinical pilot TGC study. The overall approach and testing methods are easily performed and generalizable to other applications and protocols. PMID:22401331

    NASA's future robotic missions utilizing an entry system into Venus and the outer planets, namely, Saturn, Uranus, Neptune, result in extremely severe entry conditions that exceed the capabilities of state of the art low to mid density ablators such as PICA or Avcoat. Therefore mission planners typically assume the use of a fully dense carbon phenolic heat shield similar to what was flown on Pioneer Venus and Galileo. Carbon phenolic (CP) is a robust TPS material however its high density and relatively high thermal conductivity constrain mission planners to steep entries, with high heat fluxes and pressures and short entry durations, in order for CP to be feasible from a mass perspective. The high entry conditions pose challenges for certification in existing ground based test facilities and the longer-­-term sustainability of CP will continue to pose challenges. In 2012 the Game Changing Development Program (GCDP) in NASA's Space Technology Mission Directorate funded NASA ARC to investigate the feasibility of a Woven Thermal Protection System (WTPS) to meet the needs of NASA's most challenging entry missions. This project was highly successful demonstrating that a Woven TPS solution compares favorably to CP in performance in simulated reentry environments and provides the opportunity to manufacture graded materials that should result in overall reduced mass solutions and enable a much broader set of missions than does CP. Building off the success of the WTPS project GCDP has funded a follow on project to further mature and scale up the WTPS concept for insertion into future NASA robotic missions. The matured WTPS will address the CP concerns associated with ground based test limitations and sustainability. This presentation will briefly discuss results from the WTPS Project and the plans for WTPS maturation into a heat-­-shield for extreme entry environment.

    In this paper, the drag-based trajectory tracking guidance problem is investigated for Mars entry vehicle subject to uncertainties. A composite super twisting sliding mode control method based on finite-time disturbance observer is proposed for guidance law design. The proposed controller not only eliminates the effects of matched and mismatched disturbances due to uncertainties of atmospheric models and vehicle aerodynamics but also guarantees the continuity of control action. Numerical simulations are carried out on the basis of Mars Science Laboratory mission, where the results show that the proposed methods can improve the Mars entry guidance precision as compared with some existing guidance methods including PID and ADRC.

    2012-01-01

    In order to accurately deliver an entry vehicle through the Martian atmosphere to the prescribed parachute deployment point, active Mars entry guidance is essential. This paper addresses the issue of Mars atmospheric entry guidance using the command generator tracker (CGT) based direct model reference adaptive control to reduce the adverse effect of the bounded uncertainties on atmospheric density and aerodynamic coefficients. Firstly, the nominal drag acceleration profile meeting a variety of constraints is planned off-line in the longitudinal plane as the reference model to track. Then, the CGT based direct model reference adaptive controller and the feed-forward compensator are designed to robustly track the aforementioned reference drag acceleration profile and to effectively reduce the downrange error. Afterwards, the heading alignment logic is adopted in the lateral plane to reduce the crossrange error. Finally, the validity of the guidance algorithm proposed in this paper is confirmed by Monte Carlo simulation analysis.

  15. Supporting Reporting: On the Positive Effects of Text- and Video-Based Awareness Material on Responsible Journalistic Suicide News Writing.

    PubMed

    Scherr, Sebastian; Arendt, Florian; Schäfer, Markus

    2016-08-16

    Suicide is a global public health problem. Media impact on suicide is well confirmed and there are several recommendations on how media should and should not report on suicide to minimize the risk of copycat behavior. Those media guidelines have been developed to improve responsible reporting on suicide (RRS). Although such guidelines are used in several countries, we lack empirical evidence on their causal effect on actual journalistic news writing. We conducted an experiment with journalism students (N = 78) in Germany in which we tested whether exposure to awareness material promoting RRS influences news writing. As a supplement to the widely used text-based material, we tested the impact of a video in which a suicide expert presents the guidelines. A video was used as a supplement to text partly due to its potential benefit for prevention efforts over the Internet. We chose a low-budget production process allowing easy reproduction in different countries by local suicide experts. In the experiment, participants were either exposed to written, audio-visual, or no awareness material. Afterwards, participants read numerous facts of an ostensible suicide event and were asked to write a factual suicide news story based on these facts. Analyses indicate that awareness material exposure helped to improve RRS with the awareness video showing the strongest effects. We recommend that suicide prevention should use instructive awareness videos about RRS complementary to text-based awareness material.

    This study assesses the feasibility of pen-based remote data entry and measures the acceptance of such systems by patients and physicians. Three clinical investigators participated in a phase-I/II clinical trial of escalated doses of chemotherapy followed by Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF). The study included 20 patients with testicular cancer who were treated at three university hospitals. The patients' data obtained in this trial were recorded and stored on a pen-based computer system. A total of 798 data points were recorded for each patient using 33 electronic forms resembling the paper forms used during an earlier phase of the study. The data recorded include the past medical history, inclusion/exclusion criteria, disease staging, therapy documentation, laboratory values and side effects. Both physicians and patients were interviewed directly after using the pen-based remote data entry system. Patients accepted that their physician was taking notes on an electronic form rather than on paper. All patients noted that a pen-based system is superior to a desktop computer when used during an interview. For the investigators electronic data entry takes additional effort, but time savings are realized later with less data clearing and increased data quality. These benefits are important for the study sponsor as well. In conclusion, pen-based remote data entry is a feasible new mode of recording clinical data with concrete benefits to both investigators and sponsors.

  2. A beacon configuration optimization method based on Fisher information for Mars atmospheric entry

    Zhao, Zeduan; Yu, Zhengshi; Cui, Pingyuan

    2017-04-01

    The navigation capability of the proposed Mars network based entry navigation system is directly related to the beacon number and the relative configuration between the beacons and the entry vehicle. In this paper, a new beacon configuration optimization method is developed based on the Fisher information theory and this method is suitable for any number of visible beacons. The proposed method can be used for the navigation schemes based on range measurements provided by radio transceivers or other sensors for Mars entry. The observability of specific state is defined as its Fisher information based on the observation model. The overall navigation capability is improved by maximizing the minimum average Fisher information, even though the navigation system is not fully observed. In addition, when there is only one beacon capable of entry navigation and the observation information is relatively limited, the optimization method can be modulated to maximize the Fisher information of the specific state which may be preferred for the guidance and control system to improve its estimation accuracy. Finally, navigation scenarios consisted of 1-3 beacons are tested to validate the effectiveness of the developed optimization method. The extended Kalman filter (EKF) is employed to derive the state estimation error covariance. The results also show that the zero-Fisher information situation should be avoided, especially when the dynamic system is highly nonlinear and the states change dramatically.

    Earth-based observations of Jupiter indicate that the Galileo probe probably entered Jupiter's atmosphere just inside a region that has less cloud cover and drier conditions than more than 99 percent of the rest of the planet. The visual appearance of the clouds at the site was generally dark at longer wavelengths. The tropospheric and stratospheric temperature fields have a strong longitudinal wave structure that is expected to manifest itself in the vertical temperature profile.

  14. Computer-based physician order entry: the state of the art.

    Sittig, D F; Stead, W W

    1994-01-01

    Direct computer-based physician order entry has been the subject of debate for over 20 years. Many sites have implemented systems successfully. Others have failed outright or flirted with disaster, incurring substantial delays, cost overruns, and threatened work actions. The rationale for physician order entry includes process improvement, support of cost-conscious decision making, clinical decision support, and optimization of physicians' time. Barriers to physician order entry result from the changes required in practice patterns, roles within the care team, teaching patterns, and institutional policies. Key ingredients for successful implementation include: the system must be fast and easy to use, the user interface must behave consistently in all situations, the institution must have broad and committed involvement and direction by clinicians prior to implementation, the top leadership of the organization must be committed to the project, and a group of problem solvers and users must meet regularly to work out procedural issues. This article reviews the peer-reviewed scientific literature to present the current state of the art of computer-based physician order entry. PMID:7719793

  15. A Model Based on Facilitated Passive Diffusion is Needed to Describe Root Water Entry through Aquaporins.

    PubMed

    Beaudette, Pc; Salon, C; Emery, Rjn

    2007-09-01

    Despite abundant evidence that water transfer from soil to xylem occurs along a pathway regulated by aquaporins (AQPs) water entry is still modeled using principles of ordinary passive diffusion. Problems with this model have been known for some time and include variable intrinsic properties of conductivity Lp, changing reflection coefficients, sigma, and an inability to accurately resolve osmotic differentials between the soil and xylem. Here we propose a model of water entry based on principles of facilitated passive diffusion and following Michaelis-Menten formalism. If one accepts that water entry is controlled, at least in part, by AQPs, then a model of ordinary passive diffusion is precluded, as it does not allow for facilitation kinetics. By contrast, recognition of facilitated water entry through protein channels could explain shortcomings of ordinary passive diffusion, such as diurnal variability in conductivity which we have recently shown is directly correlated to diurnal changes in PsPIP2-1 mRNA levels in Pisum sativum.

  16. Simulation-Based Analysis of Reentry Dynamics for the Sharp Atmospheric Entry Vehicle

    Tillier, Clemens Emmanuel

    1998-01-01

    This thesis describes the analysis of the reentry dynamics of a high-performance lifting atmospheric entry vehicle through numerical simulation tools. The vehicle, named SHARP, is currently being developed by the Thermal Protection Materials and Systems branch of NASA Ames Research Center, Moffett Field, California. The goal of this project is to provide insight into trajectory tradeoffs and vehicle dynamics using simulation tools that are powerful, flexible, user-friendly and inexpensive. Implemented Using MATLAB and SIMULINK, these tools are developed with an eye towards further use in the conceptual design of the SHARP vehicle's trajectory and flight control systems. A trajectory simulator is used to quantify the entry capabilities of the vehicle subject to various operational constraints. Using an aerodynamic database computed by NASA and a model of the earth, the simulator generates the vehicle trajectory in three-dimensional space based on aerodynamic angle inputs. Requirements for entry along the SHARP aerothermal performance constraint are evaluated for different control strategies. Effect of vehicle mass on entry parameters is investigated, and the cross range capability of the vehicle is evaluated. Trajectory results are presented and interpreted. A six degree of freedom simulator builds on the trajectory simulator and provides attitude simulation for future entry controls development. A Newtonian aerodynamic model including control surfaces and a mass model are developed. A visualization tool for interpreting simulation results is described. Control surfaces are roughly sized. A simple controller is developed to fly the vehicle along its aerothermal performance constraint using aerodynamic flaps for control. This end-to-end demonstration proves the suitability of the 6-DOF simulator for future flight control system development. Finally, issues surrounding real-time simulation with hardware in the loop are discussed.

    Dai, Juan; Gao, Ai; Xia, Yuanqing

    2017-03-01

    A robust entry guidance law based on terminal sliding mode and second-order differentiator is designed for trajectory tracking in this paper. The bank angle is regarded as the control variable. A novel nonlinear compound controller is designed to make the system with the trajectory-tracking error and its rate as states be input-to-state stable (ISS) with respect to uncertainties. The terminal sliding mode controller is designed to the problem of entry guidance by using the second-order differentiator to estimate the total disturbances. The proposed nonlinear compound control law by employing the second-order differentiator and the terminal sliding mode controller, provide robustness, higher control precision. Also, simulation results are presented to illustrate the effectiveness of the control strategy.

  20. Hypersonic entry vehicle state estimation using nonlinearity-based adaptive cubature Kalman filters

    NASA Astrophysics Data System (ADS)

    Sun, Tao; Xin, Ming

    2017-05-01

    Guidance, navigation, and control of a hypersonic vehicle landing on the Mars rely on precise state feedback information, which is obtained from state estimation. The high uncertainty and nonlinearity of the entry dynamics make the estimation a very challenging problem. In this paper, a new adaptive cubature Kalman filter is proposed for state trajectory estimation of a hypersonic entry vehicle. This new adaptive estimation strategy is based on the measure of nonlinearity of the stochastic system. According to the severity of nonlinearity along the trajectory, the high degree cubature rule or the conventional third degree cubature rule is adaptively used in the cubature Kalman filter. This strategy has the benefit of attaining higher estimation accuracy only when necessary without causing excessive computation load. The simulation results demonstrate that the proposed adaptive filter exhibits better performance than the conventional third-degree cubature Kalman filter while maintaining the same performance as the uniform high degree cubature Kalman filter but with lower computation complexity.

  1. Understanding Public Perceptions of the HPV Vaccination Based on Online Comments to Canadian News Articles

    Background Given the variation in human papillomavirus (HPV) vaccine coverage across Canada, and debate regarding delivery of HPV vaccines in Catholic schools, we studied online comments on Canadian news websites to understand public perceptions of HPV and HPV vaccine. Methods We searched English- and French-language Canadian news websites for 2012 articles that contained the terms “HPV” or “human papillomavirus.” Articles about HPV vaccinations that contained at least one comment were included. Two researchers independently coded comments, analyzing them for emerging themes. Results We identified 3073 comments from 1198 individuals in response to 71 news articles; 630 (52.6%) individuals expressed positive sentiments about HPV vaccination (2.5 comments/individual), 404 (33.7%) were negative (3.0 comments/individual), 34 (2.8%) were mixed (1.5 comments/individual) and 130 (10.8%) were neutral (1.6 comments/individual). Vaccine-supportive commenters believed the vaccine is safe and effective. Common themes in negative comments included concerns regarding HPV vaccine safety and efficacy, distrust of pharmaceutical companies and government, and belief that school-age children are too young for HPV vaccine. Many comments focused on whether the Catholic Church has the right to inform health policy for students, and discussion often evolved into debates regarding HPV and sexual behaviour. We noted that many individuals doubted the credibility of vaccine safety information. Conclusion The majority of commenters do not appear to be against HPV vaccination, but public health messaging that focuses on both the vaccine’s safety profile, and its use as a means to prevent cancer rather than sexually transmitted HPV infection may facilitate its acceptance.

  3. How HIV-1 entry mechanism and broadly neutralizing antibodies guide structure-based vaccine design.

    Pancera, Marie; Changela, Anita; Kwong, Peter D

    2017-05-01

    An HIV-1 vaccine that elicits broadly neutralizing antibodies (bNAbs) remains to be developed. Here, we review how knowledge of bNAbs and HIV-1 entry mechanism is guiding the structure-based design of vaccine immunogens and immunization regimens. Isolation of bNAbs from HIV-1-infected donors has led to an unprecedented understanding of the sites of vulnerability that these antibodies target on the HIV-1 envelope (Env) as well as of the immunological pathways that these antibody lineages follow to develop broad and potent neutralization. Sites of vulnerability, however, reside in the context of diverse Env conformations required for HIV-1 entry, including a prefusion-closed state, a single-CD4-bound intermediate, a three-CD4-bound intermediate, a prehairpin intermediate and postfusion states, and it is not always clear which structural state optimally presents a particular site of vulnerability in the vaccine context. Furthermore, detailed knowledge of immunological pathways has led to debate among vaccine developers as to how much of the natural antibody-developmental pathway immunogens should mimic, ranging from only the recognized epitope to multiple antigens from the antibody-virus coevolution process. A plethora of information on bNAbs is guiding HIV-1-vaccine development. We highlight consideration of the appropriate structural context from the HIV-1-entry mechanism and extraordinary progress with replicating template B-cell ontogenies.

    A well-clear volume is a key component of NASA's Separation Assurance concept for the integration of UAS in the NAS. This paper proposes a mathematical definition of the well-clear volume that uses, in addition to distance thresholds, a time threshold based on time to entry point (TEP). The mathematical model that results from this definition is more conservative than other candidate definitions of the wellclear volume that are based on range over closure rate and time to closest point of approach.

    Routine capture of patient data for a computer-based patient record system remains a subject of study. Time constraints that require fast data entry and maximal expression power are in favor of free text data entry. However, using patient data directly for decision support systems, for quality assessment, etc. requires structured data entry, which appears to be more tedious and time consuming. In this paper, a prototype clinical data entry application is described that combines free text and structured data entry in one single application and allows clinicians to smoothly switch between these two different input styles. A knowledge base involving a semantic network of clinical data entry terms and their properties and relationships is used by this application to support structured data entry. From structured data, sentences are generated and shown in a text processor together with the free text. This presentation metaphor allows for easy integrated presentation of structured data and free text. Images Figure 1 Figure 2 PMID:9929186

    2014-01-01

    Graduate medical education is undergoing a dramatic shift toward competency-based assessment of learners. Competency assessment requires clear definitions of competency and validated assessment methods. The purpose of this study is to identify criteria used by surgical educators to judge competence in Practice-Based Learning and Improvement (PBL&I) as demonstrated in learning portfolios. A total of 6 surgical learning and instructional portfolio entries served as documents to be assessed by 3 senior surgical educators. These faculty members were asked to rate and then identify criteria used to assess PBL&I competency. Individual interviews and group discussions were conducted, recorded, and transcribed to serve as the study dataset. Analysis was performed using qualitative methodology to identify themes for the purpose of defining competence in PBL&I. The assessment themes derived are presented with narrative examples to describe the progression of competency. The collaborative coding process resulted in identification of 7 themes associated with competency in PBL&I related to surgical learning and instructional portfolio entries: (1) self-awareness regarding effect of actions; (2) identification and thorough description of learning goals; (3) cases used as catalyst for reflection; (4) reconceptualization with appropriate use and critique of cited literature; (5) communication skills/completeness of entry template; (6) description of future behavioral change; and (7) engagement in process--identifies as personally relevant. The identified themes are consistent with and complement other criteria emerging from reflective practice literature and experiential learning theory. This study provides a foundation for further development of a tool for assessing learner portfolios consistent with the Accreditation Council for Graduate Medical Education's Next Accreditation System requirements.

    The Internet news are texts which involve from various fields, therefore, when a text data that will show a rapid increase of the number of dimensions of feature vectors of Self-Organizing Map (SOM) is added, these results cannot be reflected to learning. Furthermore, it is difficult for users to recognize the learning results because SOM can not produce any label information by each cluster. In order to solve these problems, we propose SOM with additional learning and dimensional by category mapping which is based on the category structure of Wikipedia. In this method, input vector is generated from each text and the corresponding Wikipedia categories extracted from Wikipedia articles. Input vectors are formed in the common category taking the hierarchical structure of Wikipedia category into consideration. By using the proposed method, the problem of reconfiguration of vector elements caused by dynamic changes in the text can be solved. Moreover, information loss in newly obtained index term can be prevented.

    Listeria monocytogenes is a Gram-positive bacterium and a facultative intracellular pathogen that invades mammalian cells, disrupts its internalization vacuole, and proliferates in the host cell cytoplasm. Here, we describe a novel image-based microscopy assay that allows discrimination between cellular entry and vacuolar escape, enabling high-content screening to identify factors specifically involved in these two steps. We first generated L. monocytogenes and Listeria innocua strains expressing a β-lactamase covalently attached to the bacterial cell wall. These strains were then incubated with HeLa cells containing the Förster resonance energy transfer (FRET) probe CCF4 in their cytoplasm. The CCF4 probe was cleaved by the bacterial surface β-lactamase only in cells inoculated with L. monocytogenes but not those inoculated with L. innocua, thereby demonstrating bacterial access to the host cytoplasm. Subsequently, we performed differential immunofluorescence staining to distinguish extracellular versus total bacterial populations in samples that were also analyzed by the FRET-based assay. With this two-step analysis, bacterial entry can be distinguished from vacuolar rupture in a single experiment. Our novel approach represents a powerful tool for identifying factors that determine the intracellular niche of L. monocytogenes.

  14. Preventing lethal violence in schools: the case for entry-based weapons screening.

    2002-04-01

    Violence-related behavior in schools has declined in recent years, but the perception of risk remains high. Disturbingly high percentages of students and teachers report staying home out of fear, and many students bring weapons to school for protection. Current proposals for preventing school violence include punishing the violence-prone, expulsion for weapon carriers, and creating a culture of nonviolence through various behavioral methods like conflict resolution. None of these proposals address the issue of lethal violence and hence personal safety. The risk of lethal violence in schools (related mainly to firearms) could be substantially reduced by creating an effective barrier between firearms and people. This could be achieved by using entry-based weapons detection systems similar to those now used in airports and courts. Decreasing the risk and fear of violence by converting schools into weapons-free zones would also be expected to increase attendance and improve scholastic performance. Randomized, controlled studies should be undertaken to evaluate the efficacy and cost-effectiveness of entry-based weapons detection systems for achieving these outcomes.

    NASA Astrophysics Data System (ADS)

    Yu, Wenbin; Chen, Wanchun

    2015-05-01

    In this paper, first, we develop new analytical solutions to hypersonic gliding problem. In the derivation of these solutions, we propose an innovative method based on spectral decomposition for solving a special type of linear system with variable coefficients, where the system matrix can be expressed as the product of a scale function and a constant matrix. Next, we design an entry guidance based on these analytical solutions. In the guidance, the downrange analytical expression is used to plan the longitudinal reference profile satisfying the downrange requirement in real time. Two bank reversals are needed to eliminate the crossrange error. The first is planned by the crossrange analytical expression such that the second is at a specified point near the end of the flight. After the first bank reversal is performed, the second is slightly corrected using the trajectory simulation. Because the longitudinal reference profile and bank reversals are planned onboard, the entry guidance can handle various urgent tasks and deal well with large dispersions in the initial conditions, aerodynamic model and atmospheric model.

  17. Sensitivity analysis and probabilistic re-entry modeling for debris using high dimensional model representation based uncertainty treatment

    Well-known tools developed for satellite and debris re-entry perform break-up and trajectory simulations in a deterministic sense and do not perform any uncertainty treatment. The treatment of uncertainties associated with the re-entry of a space object requires a probabilistic approach. A Monte Carlo campaign is the intuitive approach to performing a probabilistic analysis, however, it is computationally very expensive. In this work, we use a recently developed approach based on a new derivation of the high dimensional model representation method for implementing a computationally efficient probabilistic analysis approach for re-entry. Both aleatoric and epistemic uncertainties that affect aerodynamic trajectory and ground impact location are considered. The method is applicable to both controlled and un-controlled re-entry scenarios. The resulting ground impact distributions are far from the typically used Gaussian or ellipsoid distributions.

  18. Entry into community-based nursing practice: perceptions of prospective employers.

    1998-01-01

    To better prepare new graduates for entry-level positions in community settings, faculty of one college of nursing gathered information using focus groups of prospective employers. The groups were to identify the skills and qualities nurses need to practice in the community and ways to redesign nursing curricula to better prepare undergraduates for community-based practice. Data for this qualitative study were collected in five separate focus groups conducted with prospective employers (N = 18) from four major areas of Kentucky. By collaborating with prospective employers in the community, a partnership was established between nurse educators and community health leaders to improve the marketability of baccalaureate graduates. Assessment was the most frequently named skill essential to nursing practice in the community. Independence, critical thinking, collaboration, and confidence consistently emerged as important skills and qualities. Prospective employers were positive about developing partnerships to improve under-graduate nursing curricula. Recommendations for curricula to better prepare undergraduates for community-based practice are suggested.

    2001-07-01

    The computer-based Physician Order Entry System (POES) has been employed in many clinical institutes in Taiwan. Most of the POES systems are developed in the two-tier client-server architecture, and a large portion of the systems are constructed on a mainframe or even a single PC. The exponential growth of the Internet has had a tremendous impact on our society in recent years. In consideration of the future user interface and system architecture, we have developed a three-tier web-based Physician Order Entry System and successfully deployed it in the Wang-Fang Hospital in Taipei. The system is the first POES based on three-tier and World Wide Web (WWW) in Taiwan. The system provides the Subjective, Objective, Assessment, and Plan (SOAP) structure for the physician to enter subject, object, diagnoses, medicine dosage, treatment and laboratory test request, and prints out the prescription and necessary document. The doctor can also retrieve the patient's medical record on the system. One of the special characteristics of the system is its personalized design. The doctor can define their own diagnosis, medicine and treatment database and any combination of these to facilitate their clinical work. The system has been reviewed since February 1999. The result shows that the clinical procedure has become more efficient, and the chances of omission have been reduced. The system is very stable and the Open Database Connectivity (ODBC) database access did not show any delay in the network. Since we have incorporated many new web-programming techniques, the progress of the techniques will improve the system performance in the future.

  1. Internal ribosome entry site-based vectors for combined gene therapy.

    2015-02-20

    Gene therapy appears as a promising strategy to treat incurable diseases. In particular, combined gene therapy has shown improved therapeutic efficiency. Internal ribosome entry sites (IRESs), RNA elements naturally present in the 5' untranslated regions of a few mRNAs, constitute a powerful tool to co-express several genes of interest. IRESs are translational enhancers allowing the translational machinery to start protein synthesis by internal initiation. This feature allowed the design of multi-cistronic vectors expressing several genes from a single mRNA. IRESs exhibit tissue specificity, and drive translation in stress conditions when the global cell translation is blocked, which renders them useful for gene transfer in hypoxic conditions occurring in ischemic diseases and cancer. IRES-based viral and non viral vectors have been used successfully in preclinical and clinical assays of combined gene therapy and resulted in therapeutic benefits for various pathologies including cancers, cardiovascular diseases and degenerative diseases.

    News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include:

    The European Space Agency ESA, has engaged in 2004, the IXV project (Intermediate eXperimental Vehicle) which is part of the FLPP (Future Launcher Preparatory Programme) aiming at answering to critical technological issues for controlled re-entry, while supporting the future generation launchers and to improve in general European capabilities in the strategic field of atmospheric re-entry for future space transportation, exploration and scientific applications. The IXV key mission and system objectives are the design, development, manufacturing, assembling and on- ground to in-flight verification of an autonomous European lifting and aerodynamically controlled re- entry system, integrating the critical re- entry technologies at the system level. In particular, the IXV shall demonstrate system integrated key technologies such as lifting flight control by means of aerodynamic surfaces that are one of the main primary objectives of the experimental investigation. Lifting and aerodynamic controlled re-entry represents a significant capability advancement with respect to the ballistic re-entry of capsules like the ARD. Since hypersonic aerodynamics is essentially different from supersonic aerodynamics, the current mission is to perform an atmospheric re-entry in combination with a safe recovery the in supersonic flight regime. However, mission extension to trimmed transonic flight is under consideration based on a preliminary analysis of the aerodynamic characteristics of the IXV configuration. Since the beginning of the IXV project, an aerodynamic data base (AEDB) has been built up and continuously updated integrating the additional information mainly provided by means of CFD (ie: Euler and Navier-Stokes) and lately also by means of WTTs. This AEDB serves for flying qualities analysis and for re-entry simulations. During the development phase B2/C1, the effectiveness of the control surfaces and their impact on te vehicle's aerodynamic forces in the supersonic regime is

    Dengue is a mosquito-borne virus that has become a major public health concern worldwide in recent years. However, the current treatment for dengue disease is only supportive therapy, and no specific antivirals are available to control the infections. Therefore, the need for safe and effective antiviral drugs against this virus is of utmost importance. Entry of the dengue virus (DENV) into a host cell is mediated by its major envelope protein, E. The crystal structure of the E protein reveals a hydrophobic pocket occupied by the detergent n-octyl-β-d-glucoside (β-OG) lying at a hinge region between domains I and II, which is important for the low-pH-triggered conformational rearrangement required for fusion. Thus, the E protein is an attractive target for the development of antiviral agents. In this work, we performed prospective docking-based virtual screening to identify small molecules that likely bind to the β-OG binding site. Twenty-three structurally different compounds were identified and two of them had an EC50 value in the low micromolar range. In particular, compound 2 (EC50=3.1μM) showed marked antiviral activity with a good therapeutic index. Molecular dynamics simulations were used in an attempt to characterize the interaction of 2 with protein E, thus paving the way for future ligand optimization endeavors. These studies highlight the possibility of using a new class of DENV inhibitors against dengue. Copyright © 2017 Elsevier Ltd. All rights reserved.

  15. Omnidirectional autonomous entry guidance based on 3-D analytical glide formulas.

    2016-11-01

    An autonomous entry guidance law is developed based on 3-D analytical glide formulas, where the downrange formula is used to plan the longitudinal reference profile in order to meet the downrange and final energy requirements, and the crossrange formula is used to regulate the bank reversals in order to eliminate the crossrange error. As the analytical glide formulas ignore the effects of the Earth׳s rotation, a series of strategies is proposed for compensating these effects, which provides the guidance with the capability of steering the hypersonic glide vehicle with high Lift to Drag ratio (L/D) to any place of the world accurately. The compensation strategies can be summarized into two parts: (1) the reference profiles are properly adjusted by roughly evaluating the effects of the Earth׳s rotation on the aerodynamic profiles over the whole flight, which can compensate most of the effects; (2) the current effects are accurately evaluated and then the guidance commands are slightly modulated for compensating the remaining effects. Due to careful design, the strategies will not result in drastic changes in the Angle of Attack (AOA) and can keep the bank angle almost constant during most of flight.

  16. A template-based computerized instruction entry system helps the comunication between doctors and nurses.

    In a hospital, doctors and nurses shares roles in treating admitted patients. Communication between them is necessary and communication errors become the problem in medical safety. In Japan, verbal instruction is prohibited and doctors write their instruction on paper instruction slips. However, because it is difficult to ascertain revision history and the active instructions on instruction slips, human errors can occur. We developed template-based computerized instruction entry system to reduce ward workloads and contribute to medical safety. Templates enable us to input the instructions easily and standardize the descriptions of instructions. By standardizing and combine the instruction into one template for one instruction item, the systems could prevent instructions overlap. We created sets of templates (e.g., admission set, preoperative set), so that doctors could enter their instructions easily. Instructions entered via any of the sets can be subdivided into separate items by the system before being submitted, and can also be changed on a per-item basis. The instructions were displayed as calendar form. Calendar form represents the instruction shift and current active instructions. We prepared 382 standardized instruction templates. In our system, 66% of instructions were entered via templates, and 34% were entered as free-text comments. Our system prevents communication errors between medical staff.

  17. Diagnosing and treating Enquiry Based Learning fatigue in Graduate Entry Nursing students.

    2017-09-09

    The use of student directed study approaches such as Enquiry Based Learning (EBL) in the design and implementation of Graduate Entry Nursing Circular is well established. The rational relates to the maximisation of graduate attributes such as motivation to learn, the ability to identify, search and assimilate relevant literature and the desire to take ownership of the direction and pace of learning. Existing alongside this however, is the observation that students remain under confident in the application of knowledge to a clinical context and frustrated with learning approaches which do not appear directly related to improving their competence in this area. We suggest the result of this is a gradual disengagement and dissatisfaction the learning forum amongst students and faculty, which we have defined as EBL fatigue. The symptoms and consequences of EBL fatigue amongst students and faculty are discussed alongside strategies which we suggest may act as preventative measures in reducing the risk of a local epidemic.

    2007-01-01

    Decisions about curricular content in entry-level health professional programs are influenced by a variety of external and internal factors. However, little is known about how lecturers make decisions about the curricular content to be included or excluded from entry-level programs. This study aimed to explore the factors influencing such decision making regarding curricular content in entry-level Australian and New Zealand programs for physiotherapy, as well as how evidence-based practice (EBP) is integrated into the teaching and learning framework. Thirteen lecturers from 13 institutions (100% response rate) responsible for teaching a core part of physiotherapy practice, electrophysical agents, participated in a semistructured telephone interview. Decision making for curricular content involved an overall democratic process with the program team, but the day-to-day content was determined by the lecturer. Factors that lecturers reported as impacting on the choice of curriculum were current clinical practice, evidence, and accreditation or registration requirements. Thematic analysis of open-ended questions identified four main themes relating to the integration of the EBP paradigm within teaching: resource materials, use of broad definitions of evidence, inclusion of specific instructional strategies, and context of curriculum. Lecturers used a variety of research methodologies as a backdrop for the presentation of techniques and interventions that are used commonly in clinical practice despite limitations in the evidence base. The results highlighted tensions that exist when designing entry-level curricula with the need to prepare competent and safe practitioners while working within an EBP paradigm.

    We study complementary navigation of news and blog, where Wikipedia entries are utilized as fundamental knowledge source for linking news articles and blog feeds/posts. In the proposed framework, given a topic as the title of a Wikipedia entry, its Wikipedia entry body text is analyzed as fundamental knowledge source for the given topic, and terms strongly related to the given topic are extracted. Those terms are then used for ranking news articles and blog posts. In the scenario of complementary navigation from a news article to closely related blog posts, Japanese Wikipedia entries are ranked according to the number of strongly related terms shared by the given news article and each Wikipedia entry. Then, top ranked 10 entries are regarded as indices for further retrieving closely related blog posts. The retrieved blog posts are finally ranked all together. The retrieved blog posts are then shown to users as blogs of personal opinions and experiences that are closely related to the given news article. In our preliminary evaluation, through an interface for manually selecting relevant Wikipedia entries, the rate of successfully retrieving relevant blog posts improved.

The IXV key mission and system objectives are the design, development, manufacturing, assembling and on-ground to in-flight verification of an autonomous European lifting and aerodynamically controlled re-entry system, integrating the critical re-entry technologies at the system level. The current IXV vehicle is a slender body type exhibiting rounded shape, thick body controlled by means of two control surfaces. The current mission is to perform an atmospheric re- entry ended by a safe recovery in supersonic regime. A potential extension of the flight domain down to the transonic regime was proposed to be analyzed. The objectives were to study the capability of the IXV for flying autonomously enabling a recovery of the vehicle by means of a subsonic parachute based DRS. The vehicle designed for the hypersonic speeds integrating a large base with only two control surfaces located close to the plane of symmetry is definitively not tuned for transonic ones. CFD done by Thales Alenia Space and wind tunnel activities involving FOI T1500 facility contributed to built up an Aerodynamic Data Base (AEDB) to be used as inputs for flying qualities analysis and re-entry simulations. The paper presents the main objectives of the transonic activities with emphasis on CFD and WTT including a description of the different prediction tools and discussing the main outcomes of the current data comparisons.

    2011-09-01

    Personal reports of receiving bad news provide data that describes patients' comprehension, reflections, experienced emotions, and an interpretative commentary with the wisdom of hindsight. Analysis of autobiographical accounts of "hearing bad news" enables the identification of patterns of how patients found out diagnoses, buffering techniques used, and styles of receiving the news. I describe how patients grapple with the news, their somatic responses to hearing, and how they struggle and strive to accept what they are hearing. I discuss metaphors used within the languages of hearing bad news. Finally, I discuss implications for a change of focus in the breaking bad news research agenda, that is, from the physician's "performance" to a patient-focused agenda.

    2017-01-01

    This review provides an overview of the development of different dendrimers, mainly polyanionic, against human immunodeficiency virus (HIV) and genital herpes (HSV-2) as topical microbicides targeting the viral entry process. Vaginal topical microbicides to prevent sexually transmitted infections such as HIV and HSV-2 are urgently needed. To inhibit HIV/HSV-2 entry processes, new preventive targets have been established to maximize the current therapies against wild-type and drug-resistant viruses. The entry of HIV/HSV-2 into target cells is a multistep process that triggers a cascade of molecular interactions between viral envelope proteins and cell surface receptors. Polyanionic dendrimers are highly branched nanocompounds with potent activity against HIV/HSV-2. Inhibitors of each entry step have been identified with regard to generations and surface groups, and possible roles for these agents in anti-HIV/HSV-2 therapies have also been discussed. Four potential binding sites for impeding HIV infection (HSPG, DC-SIGN, GSL, and CD4/gp120 inhibitors) and HSV-2 infection (HS, gB, gD, and gH/gL inhibitors) exist according to their mechanisms of action and structures. This review clarifies that inhibition of HIV/HSV-2 entry continues to be a promising target for drug development because nanotechnology can transform the field of HIV/HSV-2 prevention by improving the efficacy of the currently available antiviral treatments.

    Abstract International collaboration is important in healthcare quality evaluation; however, few international comparisons of general surgery outcomes have been accomplished. Furthermore, predictive model application for risk stratification has not been internationally evaluated. The National Clinical Database (NCD) in Japan was developed in collaboration with the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), with a goal of creating a standardized surgery database for quality improvement. The study aimed to compare the consistency and impact of risk factors of 3 major gastroenterological surgical procedures in Japan and the United States (US) using web-based prospective data entry systems: right hemicolectomy (RH), low anterior resection (LAR), and pancreaticoduodenectomy (PD). Data from NCD and ACS-NSQIP, collected over 2 years, were examined. Logistic regression models were used for predicting 30-day mortality for both countries. Models were exchanged and evaluated to determine whether the models built for one population were accurate for the other population. We obtained data for 113,980 patients; 50,501 (Japan: 34,638; US: 15,863), 42,770 (Japan: 35,445; US: 7325), and 20,709 (Japan: 15,527; US: 5182) underwent RH, LAR, and, PD, respectively. Thirty-day mortality rates for RH were 0.76% (Japan) and 1.88% (US); rates for LAR were 0.43% versus 1.08%; and rates for PD were 1.35% versus 2.57%. Patient background, comorbidities, and practice style were different between Japan and the US. In the models, the odds ratio for each variable was similar between NCD and ACS-NSQIP. Local risk models could predict mortality using local data, but could not accurately predict mortality using data from other countries. We demonstrated the feasibility and efficacy of the international collaborative research between Japan and the US, but found that local risk models remain essential for quality improvement.

  10. Mesh-Based Entry Vehicle and Explosive Debris Re-Contact Probability Modeling

    2011-01-01

    The risk to a crewed vehicle arising from potential re-contact with fragments from an explosive breakup of any jettisoned spacecraft segments during entry has long sought to be quantified. However, great difficulty lies in efficiently capturing the potential locations of each fragment and their collective threat to the vehicle. The method presented in this paper addresses this problem by using a stochastic approach that discretizes simulated debris pieces into volumetric cells, and then assesses strike probabilities accordingly. Combining spatial debris density and relative velocity between the debris and the entry vehicle, the strike probability can be calculated from the integral of the debris flux inside each cell over time. Using this technique it is possible to assess the risk to an entry vehicle along an entire trajectory as it separates from the jettisoned segment. By decoupling the fragment trajectories from that of the entry vehicle, multiple potential separation maneuvers can then be evaluated rapidly to provide an assessment of the best strategy to mitigate the re-contact risk.

    Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news on financial markets. We propose a novel measure of collective behaviour based on financial news on the Web, the News Cohesiveness Index (NCI), and we demonstrate that the index can be used as a financial market volatility indicator. We evaluate the NCI using financial documents from large Web news sources on a daily basis from October 2011 to July 2013 and analyse the interplay between financial markets and finance-related news. We hypothesise that strong cohesion in financial news reflects movements in the financial markets. Our results indicate that cohesiveness in financial news is highly correlated with and driven by volatility in financial markets.

    1960-01-01

    The technique of modulation, or variable coefficients, is discussed and the analytical formulation is reviewed. Representative numerical results of the use of modulation are shown for the lifting and nonlifting cases. These results include the effects of modulation on peak acceleration, entry corridor, and heat absorption. Results are given for entry at satellite speed and escape speed. The indications are that coefficient modulation on a vehicle with good lifting capability offers the possibility of sizable loading reductions or, alternatively, wider corridors; thus, steep entries become practical from the loading standpoint. The amount of steepness depends on the acceptable heating penalty. The price of sizable fractions of the possible gains does not appear to be excessive.

  20. Breaking bad news in cancer patients.

    2015-01-01

    In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59%) had specific training on breaking bad news. 20 doctors (33.90%) were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66%) had a consistent plan for breaking bad news. 57 (96.61%) delivered bad news in a quiet place, 53 (89.83%) ensured no interruptions and enough time, 53 (89.83%) used simple words and 54 (91.53%) checked for understanding and did not rush through the news. 46 doctors (77.97%) allowed relatives to determine patient's knowledge about the disease. There were low rates of specific training in breaking bad news. However, the selected location, the physician's speech and their plan were according to current guidelines.

  1. Optimizing intramedullary entry location on the proximal humerus based on variations of neck-shaft angle.

    2015-09-01

    The purpose of this study was to define the relationship between the humeral neck-shaft angle (NSA) and variations in the ideal entry portal aligned with the long axis of the intramedullary canal of the proximal humerus. Three-dimensional images of 36 cadaveric humeri with various NSAs were reconstructed by a computerized surgical simulation program. The anteroposterior, mediolateral, and linear distances between a line from the center of the proximal medullary canal to the bicipital groove were measured. Differences among humeri with various NSAs were analyzed. The intramedullary axis line was located a mean of 9 ± 2 mm posteriorly and 11 ± 3 mm medially from the bicipital groove. The axis line was 9 ± 2 mm posterior and 11 ± 2 mm medial with a standard NSA. The axis line in humeri with a varus NSA was 8 ± 2 mm posteriorly and 9 ± 2 mm medially, whereas the axis line was 10 ± 3 mm posteriorly and 14 ± 3 mm medially with a valgus NSA. The differences in the mediolateral distances between the groups were significant (P < .00009). Care should be taken in choosing the entry portal position in humeri with various NSAs as the entry portal position differs according to the NSA. It is recommended that the location of the entry portal be moved toward the center of the humeral head to align with the centerline of the intramedullary canal in humeri with a valgus NSA in particular.

    Emerging viruses such as Ebola virus (EBOV), Lassa virus (LASV), and avian influenza virus H5N1 (AIV) are global health concerns. Since there is very limited options (either vaccine or specific therapy) approved for humans against these viruses, there is an urgent need to develop prophylactic and therapeutic treatments. Previously we reported a high-throughput screening (HTS) protocol to identify entry inhibitors for three highly pathogenic viruses (EBOV, LASV, and AIV) using a human immunodeficiency virus-based pseudotyping platform which allows us to perform the screening in a BSL-2 facility. In this report, we have adopted this screening protocol to evaluate traditional Chinese Medicines (TCMs) in an effort to discover entry inhibitors against these viruses. Here we show that extracts of the following Chinese medicinal herbs exhibit potent anti-Ebola viral activities: Gardenia jasminoides Ellis, Citrus aurantium L., Viola yedoensis Makino, Prunella vulgaris L., Coix lacryma-jobi L. var. mayuen (Roman.) Stapf, Pinellia ternata (Thunb.) Breit., and Morus alba L. This study represents a proof-of-principle investigation supporting the suitability of this assay for rapid screening TCMs and identifying putative entry inhibitors for these viruses. J. Med.

  3. Structure-Based Mutations in the Herpes Simplex Virus 1 Glycoprotein B Ectodomain Arm Impart a Slow-Entry Phenotype

    2017-01-01

    ABSTRACT Glycoprotein B (gB) is the conserved herpesvirus fusion protein, and it is required for the entry of herpesviruses. The structure of the postfusion conformation of gB has been solved for several herpesviruses; however, the gB prefusion crystal structure and the details of how the protein refolds from a prefusion to a postfusion form to mediate fusion have not been determined. Using structure-based mutagenesis, we previously reported that three mutations (I671A, H681A, and F683A) in the C-terminal arm of the gB ectodomain greatly reduced cell-cell fusion. This fusion deficit could be rescued by the addition of a hyperfusogenic mutation, suggesting that the gB triple mutant was not misfolded. Using a bacterial artificial chromosome (BAC), we constructed two independent herpes simplex virus 1 mutant strains (gB 3A) carrying the three arm mutations. The gB 3A viruses have 200-fold smaller plaques than the wild-type virus and demonstrate remarkably delayed entry into cells. Single-step and multistep growth curves show that gB 3A viruses have delayed replication kinetics. Interestingly, incubation at 40°C promoted the entry of the gB 3A viruses. We propose that the gB 3A viruses’ entry deficit is due to a loss of interactions between residues in the gB C-terminal arm and the coiled-coil core of gB. The results suggest that the triple alanine mutation may destabilize the postfusion gB conformation and/or stabilize the prefusion gB conformation and that exposure to elevated temperatures can overcome the defect in gB 3A viruses.

    Harpold, J. C.; Graves, C. A., Jr.

    1978-01-01

    This paper describes the design of the entry guidance for the Space Shuttle Orbiter. This guidance provides the steering commands for trajectory control from initial penetration of the earth's atmosphere until the terminal area guidance is activated at an earth-relative speed of 2500 fps. At this point, the Orbiter is at a distance of about 50 nmi from the runway threshold, and at an altitude of about 80,000 ft. The entry guidance design is based on an analytic solution of the equations of motion defining the drag acceleration profile that meets the terminal criteria of the entry flight while maintaining the flight within systems and operational constraints. Guidance commands, which are based on a control law that ensures damping of oscillatory type trajectory motion, are computed to steer the Orbiter to this drag acceleration profile.

  19. A flexible-segment-model-based dynamics calculation method for free hanging marine risers in re-entry

    NASA Astrophysics Data System (ADS)

    Xu, Xue-song; Wang, Sheng-wei

    2012-03-01

    In re-entry, the drilling riser hanging to the holding vessel takes on a free hanging state, waiting to be moved from the initial random position to the wellhead. For the re-entry, dynamics calculation is often done to predict the riser motion or evaluate the structural safety. A dynamics calculation method based on Flexible Segment Model (FSM) is proposed for free hanging marine risers. In FSM, a riser is discretized into a series of flexible segments. For each flexible segment, its deflection feature and external forces are analyzed independently. For the whole riser, the nonlinear governing equations are listed according to the moment equilibrium at nodes. For the solution of the nonlinear equations, a linearization iteration scheme is provided in the paper. Owing to its flexibility, each segment can match a long part of the riser body, which enables that good results can be obtained even with a small number of segments. Moreover, the linearization iteration scheme can avoid widely used Newton-Rapson iteration scheme in which the calculation stability is influenced by the initial points. The FSM-based dynamics calculation is timesaving and stable, so suitable for the shape prediction or real-time control of free hanging marine risers.

    Chikungunya virus (CHIKV), an alphavirus, has recently caused epidemic outbreaks and is therefore considered a re-emerging pathogen for which no effective treatment is available. In this study, a CHIKV replicon containing the virus replicase proteins together with puromycin acetyltransferase, EGFP and Renilla luciferase marker genes was constructed. The replicon was transfected into BHK cells to yield a stable cell line. A non-cytopathic phenotype was achieved by a Pro718 to Gly substitution and a five amino acid insertion within non-structural protein 2 (nsP2), obtained through selection for stable growth. Characterization of the replicon cell line by Northern blotting analysis revealed reduced levels of viral RNA synthesis. The CHIKV replicon cell line was validated for antiviral screening in 96-well format and used for a focused screen of 356 compounds (natural compounds and clinically approved drugs). The 5,7-dihydroxyflavones apigenin, chrysin, naringenin and silybin were found to suppress activities of EGFP and Rluc marker genes expressed by the CHIKV replicon. In a concomitant screen against Semliki Forest virus (SFV), their anti-alphaviral activity was confirmed and several additional inhibitors of SFV with IC₅₀ values between 0.4 and 24 µM were identified. Chlorpromazine and five other compounds with a 10H-phenothiazinyl structure were shown to inhibit SFV entry using a novel entry assay based on a temperature-sensitive SFV mutant. These compounds also reduced SFV and Sindbis virus-induced cytopathic effect and inhibited SFV virion production in virus yield experiments. Finally, antiviral effects of selected compounds were confirmed using infectious CHIKV. In summary, the presented approach for discovering alphaviral inhibitors enabled us to identify potential lead structures for the development of alphavirus entry and replication phase inhibitors as well as demonstrated the usefulness of CHIKV replicon and SFV as biosafe surrogate models for anti

    Recommending news stories to users, based on their preferences, has long been a favourite domain for recommender systems research. Traditional systems strive to satisfy their user by tracing users' reading history and choosing the proper candidate news articles to recommend. However, most of news websites hardly require any user to register before reading news. Besides, the latent relations between news and microblog, the popularity of particular news, and the news organization are not addressed or solved efficiently in previous approaches. In order to solve these issues, we propose an effective personalized news recommendation method based on microblog user profile building and sub class popularity prediction, in which we propose a news organization method using hybrid classification and clustering, implement a sub class popularity prediction method, and construct user profile according to our actual situation. We had designed several experiments compared to the state-of-the-art approaches on a real world dataset, and the experimental results demonstrate that our system significantly improves the accuracy and diversity in mass text data.

  13. Do you want the good news or the bad news first? The nature and consequences of news order preferences.

    PubMed

    Legg, Angela M; Sweeny, Kate

    2014-03-01

    Information often comes as a mix of good and bad news, prompting the question, "Do you want the good news or the bad news first?" In such cases, news-givers and news-recipients differ in their concerns and considerations, thus creating an obstacle to ideal communication. In three studies, we examined order preferences of news-givers and news-recipients and the consequences of these preferences. Study 1 confirmed that news-givers and news-recipients differ in their news order preferences. Study 2 tested two solutions to close the preference gap between news-givers and recipients and found that both perspective-taking and priming emotion-protection goals shift news-givers' delivery patterns to the preferred order of news-recipients. Study 3 provided evidence that news order has consequences for recipients, such that opening with bad news (as recipients prefer) reduces worry, but this emotional benefit undermines motivation to change behavior.

  2. Blended news delivery in healthcare: a framework for injecting good news into bad news conversations.

    PubMed

    Legg, Angela M; Sweeny, Kate

    2015-01-01

    Clinicians often inject good news into bad news delivery, and they do so for a variety of reasons. We present a framework that draws from research in the fields of health and social psychology to shed light on situations in which clinicians add superfluous good news into bad news conversations in an effort to ease the conversation or mitigate patients' distress, a broad strategy we refer to as blended news delivery. Our framework includes predictors of clinicians' use of blended news delivery, characteristics of blended news and outcomes of this strategy for both patients and clinicians. This framework addresses a common aspect of health communication and can direct future research on ideal strategies for and likely consequences of blended news delivery and communication more broadly.

  3. Project-based fieldwork: perspectives of graduate entry students and project sponsors.

    PubMed

    Fortune, Tracy; McKinstry, Carol

    2012-08-01

    This article builds on an earlier viewpoint regarding the need for project-focussed fieldwork. It presents the findings of an evaluative study into the value of project placements undertaken by final year graduate entry master's students as part of a capstone subject. The authors argue that provision of project placements enable impending graduates to develop and implement macro level strategies to develop prevention, resource and service development skills often required of contemporary occupational therapy practitioners. A qualitative approach is adopted. Student cohorts from 2005 and 2006 completed open-ended, written questionnaires, and agency project sponsors were interviewed to obtain their perspectives of the project placement experience. Despite some concern that project placements might be undertaken at the expense of 'clinical' placements these findings reveal that projects managed by students were perceived by services to add great value enabling them to advance important priorities. Students and sponsors highlighted a range of positive learning outcomes, including the ability to work collaboratively with supervisors and develop advanced communication skills and political acumen. The success of such placements depends on supportive supervision from academic staff. CONCLUSIONS AND SIGNIFICANCE OF THE STUDY: The findings promote project placements as a highly authentic aspect of work integrated learning enabling learners to draw together a range of attributes that support the ability to manage complex issues that have occupational relevance at a macro level. In addition, such experiences help learners to develop agency and political acumen both increasingly important capabilities for the contemporary workplace. © 2012 The Authors Australian Occupational Therapy Journal © 2012 Occupational Therapy Australia.

  4. Perplexity analysis of obesity news coverage.

    PubMed

    McFarlane, Delano J; Elhadad, Noémie; Kukafka, Rita

    2009-11-14

    An important task performed during the analysis of health news coverage is the identification of news articles that are related to a specific health topic (e.g. obesity). This is often done using a combination of keyword searching and manual encoding of news content. Statistical language models and their evaluation metric, perplexity, may help to automate this task. A perplexity study of obesity news was performed to evaluate perplexity as a measure of the similarity of news corpora to obesity news content. The results of this study showed that perplexity increased as news coverage became more general relative to obesity news (obesity news approximately 187, general health news approximately 278, general news approximately 378, general news across multiple publishers approximately 382). This indicates that language model perplexity can measure the similarity news content to obesity news coverage, and could be used as the basis for an automated health news classifier.

  5. Activity and Safety of Synthetic Lectins Based on Benzoboroxole-Functionalized Polymers for Inhibition of HIV Entry

    PubMed Central

    Mahalingam, Alamelu; Geonnotti, Anthony R.; Balzarini, Jan; Kiser, Patrick F.

    2011-01-01

    Lectins derived from plant and microbial sources constitute a vital class of entry inhibitors that target the oligomannose residues on the HIV envelope gp120. Despite their potency and specificity, success of lectin-based entry inhibitors may be impeded by issues in regards to economical production, formulation and potential mitogenicity. Therefore, there exists a gap in the HIV therapeutics pipeline that underscores the need for mass producible, synthetic, broad-spectrum, and biocomptabile inhibitors of HIV entry. Here, we present the development of a polymeric synthetic lectin, based on benzoboroxole (BzB), which exhibits weak affinity (~25 M−1) for non-reducing sugars, similar to those found on the HIV envelope. High molecular weight BzB-functionalized polymers demonstrated antiviral activity that increased with an increase in ligand density and molecular weight of the polymer construct; revealing that polyvalency improves activity. Polymers showed significant increase in activity from 25 to 75 mol% BzB functionalization with EC50 of 15 μM and 15 nM, respectively. A further increase in mole functionalization to 90% resulted in an increase of the EC50 (59 ± 5 nM), likely due to the elongated rigid structure of the polymer chain compelled by electrostatic repulsion between the boronic acid groups. An increase in molecular weight of the polymer at 50 mol% BzB functionalization showed a gradual but significant increase in antiviral activity, with the highest activity seen with the 382 kDa polymer (EC50 of 1.1 ± 0.5 nM in CEM cells and 11 ± 3 nM in TZM-bl cells). Supplementing the polymer backbone with 10 mol% sulfonic acid not only increased the aqueous solubility of the polymers by at least 50-fold, but also demonstrated a synergistic increase in anti-HIV activity (4.0 ± 1.5 nM in TZM-bl cells), possibly due to electrostatic interactions between the negatively charged polymer backbone and the positively charged V3-loop in the gp120. The benzoboroxole

    2015-05-01

    This study considers social learning practices within and outside the overt curriculum. A thematic approach was used to analyse data from six focus group interviews with 11 graduate entry medical students from a UK university over a year of study. The results indicate that: (1) during their first year of study students form a community of learning practice, (2) this community of practice influences learning inside and outside the overt curriculum, (3) there is a changing community profile over the year of practice, (4) the students' engagement in problem-based learning (PBL) as part of their overt curriculum strongly influences the development of a community of practice and hence learning both inside and outside the overt curriculum. Findings are discussed in terms of Wenger's community of practice framework, the role of distributed cognition and social learning. It is concluded that PBL is an effective approach for academics to enrich students' social learning practices.

    2005-01-01

    In the paper 'NO News', Preston et al. (2004) make a number of erroneous assumptions regarding nitrogen oxide chemistry. These authors also present some very significant misinterpretations of previous research into the effects of various nitrogen oxides on germination of post-fire followers. Methodological differences between the study by Preston et al. (2004) and previous work are also problematic, such as using NO-donors in solution versus the use of direct application of various nitrogen oxides in the gaseous phase. A closer review of these studies, with the proper understanding of nitrogen oxide chemistry, and interpretations of the available literature, would lead to the conclusion that, contrary to the authors' assertions, the Preston et al. (2004) study supports, rather than refutes, earlier findings by Keeley and Fotheringham (1997, 1998a, b, 2000). ?? CAB International 2005.

  14. Physician-patient communication: breaking bad news.

    PubMed

    Fields, Scott A; Johnson, W Michael

    2012-01-01

    Physicians often struggle with how to manage the task of breaking bad news with patients. Moreover, the arduous nature of the task can contribute to physician detachment from the patient or an avoidance of breaking the news in a timely manner. A plan of action can only improve physician confidence in breaking bad news, and also make the task more manageable. Over a decade ago, Rabow and McPhee offered a strategy; the ABCDE plan, which provided a patient centered framework from which to deliver troubling news to patients and families. At the heart of this plan was the creation of a safe environment, the demonstration of timely communication skills, and the display of empathy on the physician's part. Careful consideration of the doctor's own reactions to death and dying also played an important role. A close review of the five tenets of this plan indicates the relevance of Rabow and McPhee's strategy today. The patient base in our nation and state continues to be older, on average, and physicians are faced with numerous patients who have terminal illness. A constructive plan with specific ideas for breaking bad news can help physicians effectively navigate this difficult task.

  15. Measuring the Interestingness of News Articles

    SciTech Connect

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

  16. A catalytically and genetically optimized beta-lactamase-matrix based assay for sensitive, specific, and higher throughput analysis of native henipavirus entry characteristics.

    PubMed

    Wolf, Mike C; Wang, Yao; Freiberg, Alexander N; Aguilar, Hector C; Holbrook, Michael R; Lee, Benhur

    2009-07-31

    Nipah virus (NiV) and Hendra virus (HeV) are the only paramyxoviruses requiring Biosafety Level 4 (BSL-4) containment. Thus, study of henipavirus entry at less than BSL-4 conditions necessitates the use of cell-cell fusion or pseudotyped reporter virus assays. Yet, these surrogate assays may not fully emulate the biological properties unique to the virus being studied. Thus, we developed a henipaviral entry assay based on a beta-lactamase-Nipah Matrix (betala-M) fusion protein. We first codon-optimized the bacterial betala and the NiV-M genes to ensure efficient expression in mammalian cells. The betala-M construct was able to bud and form virus-like particles (VLPs) that morphologically resembled paramyxoviruses. betala-M efficiently incorporated both NiV and HeV fusion and attachment glycoproteins. Entry of these VLPs was detected by cytosolic delivery of betala-M, resulting in enzymatic and fluorescent conversion of the pre-loaded CCF2-AM substrate. Soluble henipavirus receptors (ephrinB2) or antibodies against the F and/or G proteins blocked VLP entry. Additionally, a Y105W mutation engineered into the catalytic site of betala increased the sensitivity of our betala-M based infection assays by 2-fold. In toto, these methods will provide a more biologically relevant assay for studying henipavirus entry at less than BSL-4 conditions.

  17. News "Speed Dating" for Scientists and Journalists: Conveying geoscience news in haiku-short form

    As Rachel Carson wrote in her 1956 book, The Sense of Wonder, it's important for everyone to develop an appreciation of "land, sea and sky." One of the best ways of getting the word out to the public about these realms is through the media. How do scientists capture the interest of the press in a society with a seemingly shorter and shorter attention span? Studies show that as the amount of scientific jargon and number of complex concepts in a news story increase, "filter-feeding" by the public of that news declines. When scientific jargon/complex concepts are few, the public "consumes" much more news. These results also apply to news story headlines: shorter headlines get the most interest. Based on these findings, one organization has started an experiment in "scientific speed dating": giving presenters three minutes to discuss results. They may have discovered something: news coverage of the research has been excellent. In today's world, conveying news about the geosciences in haiku-short form may be the best way of relating the wonders of land, sea and sky.

    Recommender systems represent an important tool for news distribution on the Internet. In this work we modify a recently proposed social recommendation model in order to deal with no explicit ratings of users on news. The model consists of a network of users which continually adapts in order to achieve an efficient news traffic. To optimize the network's topology we propose different stochastic algorithms that are scalable with respect to the network's size. Agent-based simulations reveal the features and the performance of these algorithms. To overcome the resultant drawbacks of each method we introduce two improved algorithms and show that they can optimize the network's topology almost as fast and effectively as other not-scalable methods that make use of much more information.

    Maintenance of problem lists in electronic medical records is required for the meaningful use incentive and by the Joint Commission. Linking indication with prescribed medications using computerized physician order entry (CPOE) can improve problem list documentation. Prescribing of antihypertensive medications is an excellent target for interventions to improve indication-based prescribing because antihypertensive medications often have multiple indications and are frequently prescribed. To measure the accuracy and completeness of electronic problem list additions using indication-based prescribing of antihypertensives. Clinical decision support (CDS) was implemented so that orders of antihypertensives prompted ordering physicians to select from problem list additions indicated by that medication. An observational analysis of 1000 alerts was performed to determine the accuracy of physicians' selections. At least one accurate problem was placed 57.5% of the time. Inaccurate problems were placed 4.8% of the time. Accuracy was lower in medications with multiple indications and the likelihood of omitted problems was higher compared to medications whose only indication was hypertension. Attending physicians outperformed other clinicians. There was somewhat lower accuracy for inpatients compared to outpatients. CDS using indication-based prescribing of antihypertensives produced accurate problem placement roughly two-thirds of time with fewer than 5% inaccurate problems placed. Performance of alerts was sensitive to the number of potential indications of the medication and attendings vs. other clinicians prescribing. Indication-based prescribing during CPOE can be used for problem list maintenance, but requires optimization. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

  1. Including limitations in news coverage of cancer research: effects of news hedging on fatalism, medical skepticism, patient trust, and backlash.

    2011-05-01

    Past research has demonstrated that news coverage of cancer research, and scientific research generally, rarely contains discourse-based hedging, including caveats, limitations, and uncertainties. In a multiple message experiment (k = 4 news stories, N = 1082), the authors examined whether hedging shaped the perceptions of news consumers. The results revealed that participants were significantly less fatalistic about cancer (p = .039) and marginally less prone to nutritional backlash (p = .056) after exposure to hedged articles. Participants exposed to articles mentioning a second researcher (unaffiliated with the present study) exhibited greater trust in medical professions (p = .001). The findings provide additional support for the inclusion of discourse-based hedging in cancer news coverage and suggest that news consumers will use scientific uncertainty in illness representations.

    2006-01-01

    Scientists, observatories, academic institutions and funding agencies persistently review the usefulness and productivity of investment in scientific research. The Science News Metrics was created over 10 years ago to review NASA's performance in this arena. The metric has been useful for many years as one facet in measuring the scientific discovery productivity of NASA-funded missions. The metric is computed independently of the agency and has been compiled in a consistent manner. Examination of the metric yields year-by-year insight into NASA science successes in a world wide context. The metric has shown that NASA's contribution to worldwide top science news stories has been approximately 5% overall with the Hubble Space Telescope dominating the performance.

  8. Interim analysis based on the weighted log-rank test for delayed treatment effects under staggered patient entry.

    2016-01-01

    Fleming and Harrington's G(ρ,γ) class of weighted log-rank tests is appropriate for detecting delayed treatment effects such as those seen in cancer vaccines. A conditional power (CP) and an alpha spending function (ASF) approach are useful for interim analyses that are conducted with the aim of early termination due to futility and efficacy, respectively. However, calculation of the CP and the total Type I error probability are often not considered for delayed effects under the staggered patient entry. In this article, we first propose methods for calculating the CP analytically based on the weighted log-rank test. We compared the performances of the proposed methods with two other methods (i.e., usual log-rank test and optimal one) under the delayed alternatives. Our simulations demonstrated that the CP based on the weighted log-rank test was more powerful than that of the usual log-rank test and was comparable to the CP based on the optimal log-rank test. Second, we quantitatively evaluated the degree to which the Type I error probability was inflated when an ASF approach with forced independent increments assumption was applied to the weighted log-rank test. The proposed method will provide valuable tools in the decision-making stage of the interim analysis.

    Cole, Stephen

    The last two years have witnessed many major geophysical events such as the Loma Prieta earthquake, new insights into plate motions, new seismic and mid-ocean ridge observational programs, and new views of a distant planet. AGU's Public Information Committee, chaired by Debra Knopman of the U.S. Geological Survey, was asked by the American Institute of Physics to prepare a series of articles on the major topics in geophysics for publication in Physics News in 1990. Several of those papers did appear in the AIP publication. In the absence of a comparable publication devoted solely to a summary of news in geophysics, AGU is publishing the 20 articles solicited by the Public Information Committee as a booklet, Geophysics News 1990, that is being distributed to the media. The articles are also being published in Eos starting with this issue and continuing for the next several weeks. The topics covered in these articles range from the world's deepest rocks to the powerful blast waves from major solar flares.

  10. Contact: Releasing the news

    NASA Astrophysics Data System (ADS)

    Pinotti, Roberto

    The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

  11. Enfuvirtide (T20)-Based Lipopeptide Is a Potent HIV-1 Cell Fusion Inhibitor: Implications for Viral Entry and Inhibition.

    The peptide drug enfuvirtide (T20) is the only viral fusion inhibitor used in combination therapy for HIV-1 infection, but it has relatively low antiviral activity and easily induces drug resistance. Emerging studies demonstrate that lipopeptide-based fusion inhibitors, such as LP-11 and LP-19, which mainly target the gp41 pocket site, have greatly improved antiviral potency and in vivo stability. In this study, we focused on developing a T20-based lipopeptide inhibitor that lacks pocket-binding sequence and targets a different site. First, the C-terminal tryptophan-rich motif (TRM) of T20 was verified to be essential for its target binding and inhibition; then, a novel lipopeptide, termed LP-40, was created by replacing the TRM with a fatty acid group. LP-40 showed markedly enhanced binding affinity for the target site and dramatically increased inhibitory activity on HIV-1 membrane fusion, entry, and infection. Unlike LP-11 and LP-19, which required a flexible linker between the peptide sequence and the lipid moiety, addition of a linker to LP-40 sharply reduced its potency, implying different binding modes with the extended N-terminal helices of gp41. Also, interestingly, LP-40 showed more potent activity than LP-11 in inhibiting HIV-1 Env-mediated cell-cell fusion while it was less active than LP-11 in inhibiting pseudovirus entry, and the two inhibitors displayed synergistic antiviral effects. The crystal structure of LP-40 in complex with a target peptide revealed their key binding residues and motifs. Combined, our studies have not only provided a potent HIV-1 fusion inhibitor, but also revealed new insights into the mechanisms of viral inhibition.IMPORTANCE T20 is the only membrane fusion inhibitor available for treatment of viral infection; however, T20 requires high doses and has a low genetic barrier for resistance, and its inhibitory mechanism and structural basis remain unclear. Here, we report the design of LP-40, a T20-based lipopeptide inhibitor

    A theoretical model is derived to determine the average thermodynamic properties in the expanding region, recirculating region, recompression region, and neck region through application of one-dimensional conservation equations. Radiative transfer is calculated using spectrally detailed computer codes accounting for nonequilibrium. The results show that the most severe heating occurs immediately behind the frustum, and that the recompression and neck regions are the major sources of radiation that heats the base stagnation point, The radiation flux to the base point is slightly stronger with ablation than without. Its value is 0.11(43 P(sub b)/P(sub s))(sup 2) times that to the front stagnation point where the base pressure P(sub b) is defined as the average pressure in the recirculating region and P(sub s) is the front stagnation-point pressure. The time-integrated heat load to the base point is 18(43 P(sub b)/P(sub s))(sup 2) kJ/sq cm.

    The high cost of computerized physician order entry (CPOE) and physician resistance to standardized care have delayed implementation. An intranet-based order set system can provide some of CPOE's benefits and offer opportunities to acculturate physicians toward standardized care. INTRANET CLINICIAN ORDER FORMS (COF): The COF system at the Medical University of South Carolina (MUSC) allows caregivers to enter and print orders through the intranet at points of care and to access decision support resources. Work on COF began in March 2000 with transfer of 25 MUSC paper-based order set forms to an intranet site. Physician groups developed additional order sets, which number more than 200. Web traffic increased progressively during a 24-month period, peaking at more than 6,400 hits per month to COF. Decision support tools improved compliance with Centers for Medicare & Medicaid Services core indicators. Clinicians demonstrated a willingness to develop and use order sets and decision support tools posted on the COF site. COF provides a low-cost method for preparing caregivers and institutions to adopt CPOE and standardization of care. The educational resources, relevant links to external resources, and communication alerts will all link to CPOE, thereby providing a head start in CPOE implementation.

    The HAYABUSA asteroid explorer successfully released its sample capsule to Australia on 2010 June 13. Since the Earth reentry phase of sample return was critical, many backup plans for predicting the landing location were prepared. This paper considers the reentry dispersion using ground-based optical observation as a backup observation for radiometric observation. Several scenarios were calculated and compared for the reentry phase of HAYABUSA to evaluate the navigation accuracy of the ground-based observation. The optical observation doesn't require any active reaction from a spacecraft, and thus these results show that optical observations could be a steady backup strategy even if a spacecraft had some trouble. We also evaluated the landing dispersion of HAYABUSA only with optical observation.

    An automatic order entry system is very important for the processing of out-patient information, not only helping doctors to enter their orders directly but also reducing errors of communication. Many hospitals are anxious to set up a direct order entry system but are concerned about possible system failures. In this paper we report on an effective and efficient fault-tolerant order entry management system which satisfies the requirements for out-patient order entry. From the results of experiments on a prototype we found that the system was user friendly and reduced the time taken. Doctors are able to enter their orders more easily, accurately and quickly by selecting from the standardized and personalized menus to be found in the system.

    Two gradient-based adaptation methodologies have been implemented into the Fun3d refine GridEx infrastructure. A spring-analogy adaptation which provides for nodal movement to cluster mesh nodes in the vicinity of strong shocks has been extended for general use within Fun3d, and is demonstrated for a 70 sphere cone at Mach 2. A more general feature-based adaptation metric has been developed for use with the adaptation mechanics available in Fun3d, and is applicable to any unstructured, tetrahedral, flow solver. The basic functionality of general adaptation is explored through a case of flow over the forebody of a 70 sphere cone at Mach 6. A practical application of Mach 10 flow over an Apollo capsule, computed with the Felisa flow solver, is given to compare the adaptive mesh refinement with uniform mesh refinement. The examples of the paper demonstrate that the gradient-based adaptation capability as implemented can give an improvement in solution quality.

    PubMed Central

    2016-01-01

    The recognition of the local symmetric image within benzofuran-based natural oligostilbenoids guided us to design a modular synthetic approach to these molecules by utilizing a three-step sequence consisting of Sonogashira coupling, iodocyclization, and Suzuki coupling. During our synthesis, the relative reactivities of ester, aldehyde, and alkoxy groups on the same aryl ring toward the neighboring alkyne in the iodine-mediated cyclization reactions were explored. Starting from the symmetrical 3,5-dimethoxybenzyl alcohol, this route allowed rapid access to 2,3-diarylbenzofuran, a key intermediate to several oligostilbenoid natural products, in good overall yields.

    General descriptions in medical records are so diverse that they are usually entered as free text into an electronic medical record, and the resulting data analysis is often difficult. We developed and implemented a template-based data entry module and data analyzing system for general descriptions. We developed a template with tree structure, whose content master and entered patient's data are simultaneously expressed by XML. The entered structured data is converted to narrative form for easy reading. This module was implemented in the EMR system, and is used in 35 hospitals as of October, 2006. So far, 3725 templates (3242 concepts) have been produced. The data in XML and narrative text data are stored in the EMR database. The XML data are retrieved, and then patient's data are extracted, to be stored in the data ware-house (DWH). We developed a search assisting system that enables users to find objective data from the DWH without requiring complicated SQL. By using this method, general descriptions in medical records can be structured and made available for clinical research.

    High titers of infectious viruses for vaccine and diagnostic reference panel development are made by infecting susceptible mammalian cells. Laboratory procedures are strictly performed in a Bio-Safety Level-3 (BSL3) laboratory and each entry and exit involves the use of  disposable Personnel Protective Equipment (PPE) to observe cell culture conditions. Routine PPE use involves significant recurring costs. Alternative non-invasive optical sensor based approaches to remotely monitor cell culture may provide a promising and cost effective approach to monitor infectious virus cultures resulting in lower disruption and costs. We report here the monitoring of high titer cultures of Human Immunodeficiency Virus-1 (HIV-1) and Herpes Simplex Virus-2 (HSV-2) remotely with the use of optical oxygen sensors aseptically placed inside the cell culture vessel. The replacement of culture media for cell and virus propagation and virus load monitoring was effectively performed using this fluorescent sensor and resulted in half the number of visits to the BSL3 lab (five versus ten).

    Part of NASAs In-Space Propulsion Technology (ISPT) program is the development of the tradespace to support the design of a family of multi-mission Earth Entry Vehicles (MMEEV) to meet a wide range of mission requirements. An integrated tool called the Multi Mission System Analysis for Planetary Entry Descent and Landing or M-SAPE tool is being developed as part of Entry Vehicle Technology project under In-Space Technology program. The analysis and design of an Earth Entry Vehicle (EEV) is multidisciplinary in nature, requiring the application many disciplines. Part of M-SAPE's application required the development of parametric mass estimating relationships (MERs) to determine the vehicle's required Thermal Protection System (TPS) for safe Earth entry. For this analysis, the heat shield was assumed to be made of a constant thickness TPS. This resulting MERs will then e used to determine the pre-flight mass of the TPS. Two Mers have been developed for the vehicle forebaody. One MER was developed for PICA and the other consisting of Carbon Phenolic atop an Advanced Carbon-Carbon composition. For the the backshell, MERs have been developed for SIRCA, Acusil II, and LI-900. How these MERs were developed, the resulting equations, model limitations, and model accuracy are discussed in this poster.

Paper represents almost 40% of the waste stream, according to the US EPA. The agency`s figures show that more than 80 million tpy of paper are generated, and with such a significant portion of this waste capable of being recycled, it is essential that the nation`s capital have enough paper recycling facilities. Capital Fiber (Springfield, VA.), a large-scale intermediate paper processing facility, is an example of one such facility. Its primary material is old newspapers (ONP), and its operations consist of receiving, sorting, and consolidating waste paper for baling and resale. The company is a joint venture between daily newspaper giant the Washington Post (Washington, D.C.), which owns 80%, and the Canusa Corp. (Baltimore), a waste paper brokerage firm, which owns the other 20% of Capitol Fiber. Capital Fiber`s Springfield facility handles nine grades of paper, including pre-consumer and post-consumer ONP, blank news (newspaper trimmings that have not been printed on), old corrugated containers (OCC), sorted white ledger and sorted office waste, and various wrappers, supermixes, and other mixed grades. Within each of these categories are various sub-grades of paper, and the facility also takes old telephone books, computer paper, and flyleaf, the extra tim cut from periodicals. But, not surprisingly, the predominant material is ONP.

    As the exponential growth of news creation on the internet, the amount of digital news has reached out billion numbers. Digital news is naturally linked each other but it needs to be grouped so that user can easily classify the news that they read. Graph is the most suitable data model to represent digital news since its can describing relation in easy and flexible manner. Thus, to overcome grouping problems, in this paper we using Chinese Whispers Algorithm as the graph clustering approach. We choose Chinese Whisper Algorithm based on consideration that the algorithm is able to make clusters from a big graph data with a relatively fast process [8], that appropriate with the characteristics of digital news. In this research, we examine the graph quality by comparing intra and inter-cluster weights of every node. This scenario gives us a quite high result that 95% of nodes have intra-cluster weight higher than its inter-cluster weight. We also investigate the graph accuracy by comparing the cluster results with expert judgement. As the result, the average accuracy of digital news graph clustering using Chinese Whisper algorithm is 80%.

  5. Responding to negative health events: a test of the bad news response model.

    PubMed

    Sweeny, Kate; Shepperd, James

    2009-10-01

    People can respond to bad news in a variety of ways. The Bad News Response Model suggests that three aspects of bad news (the controllability, likelihood, and severity of negative consequences) predict which response (Watchful Waiting, Active Change, or Acceptance) people are likely to choose. This article presents an initial test of the predictions of the Bad News Response Model. College students (N = 234) and older adults (N = 116) read a scenario about a person with a suspicious mole that varied in the controllability, likelihood, and severity of the outcomes. Consistent with our predictions, people prefer Watchful Waiting when controllability, likelihood, and severity are low, Active Change when controllability and likelihood are high, and Acceptance when controllability is low. These findings provide support for the Bad News Response Model and suggest that responses to bad news may be foreseeable based on the type of news people receive.

    2001-01-01

    This study is part of the overall research effort on the role of the media in making sense of events in late modernity. The main objective is to investigate the context in which news about AIDS is produced at the interface between norms for producing news (as expressed by professional journalists) and an analysis of news stories published in four mainstream Brazilian newspapers. The results are organized in three broad topics: (a) the construction of news about AIDS; (b) the visibility of AIDS news during the study period; and (c) factors that facilitate or hinder the production of AIDS news. Important factors include exclusiveness of the story and/or novelty of the content, the notion of hot (or cold) news, and the specific contents. The authors also emphasize the inevitable chance elements associated with organizational characteristics and daily journalism. They conclude by pointing to recent changes in both the shape of the AIDS epidemic and the communications dynamics resulting from recent developments in the electronic media.

    The Universal Protein Resource (UniProt, http://www.uniprot.org ) consortium is an initiative of the SIB Swiss Institute of Bioinformatics (SIB), the European Bioinformatics Institute (EBI) and the Protein Information Resource (PIR) to provide the scientific community with a central resource for protein sequences and functional information. The UniProt consortium maintains the UniProt KnowledgeBase (UniProtKB), updated every 4 weeks, and several supplementary databases including the UniProt Reference Clusters (UniRef) and the UniProt Archive (UniParc).The Swiss-Prot section of the UniProt KnowledgeBase (UniProtKB/Swiss-Prot) contains publicly available expertly manually annotated protein sequences obtained from a broad spectrum of organisms. Plant protein entries are produced in the frame of the Plant Proteome Annotation Program (PPAP), with an emphasis on characterized proteins of Arabidopsis thaliana and Oryza sativa. High level annotations provided by UniProtKB/Swiss-Prot are widely used to predict annotation of newly available proteins through automatic pipelines.The purpose of this chapter is to present a guided tour of a UniProtKB/Swiss-Prot entry. We will also present some of the tools and databases that are linked to each entry.

    PubMed Central

    Heinrichs, Kristinn I.

    2002-01-01

    Objective: To establish the underlying theory and benefits and describe the implementation of a problem-based learning curriculum. Data Sources: I searched MEDLINE, SPORT Discus, and nursing, evidence-based medicine, and educational psychology databases from 1987 through 2002 using the terms problem-based learning, physical therapy, nursing, and medicine. Data Synthesis: In the problem-based learning process, students encounter a problem, bring to it their preconceived understanding (accurate or not), learn to identify what they need to learn to better understand the problem, engage in self-directed study, and begin to resolve the problem. Problem-based learning has its origins in medical education but is widely used in K–12 education, social sciences, health professions education, law, business administration, engineering, and aviation. An entry-level master of science degree program in athletic training based on problem-based learning and integrated clinical education is described. Conclusions/Recommendations: Problem-based learning curricula, if implemented correctly, can facilitate the entry-level athletic training student's professional development into that of a life-long learner who bases clinical decisions and procedures on the best available evidence.

    Adverse drug events occur often in hospitals. They can be prevented to a large extent by minimizing the human errors of prescription writing. To evaluate the efficacy of a computerized prescription order entry (CPOE) system with the help of ancillary support in minimizing prescription errors. Retrospective study carried out in a community-based urban teaching hospital in south Brooklyn, NY from January 2004 to January 2005. Errors were categorized into inappropriate dosage adjustment for creatinine clearance, duplication, incorrect orders, allergy verification, and incomplete orders. The pharmacists identified the type of error, the severity of error, the class of drug involved, and the department that made the error. A total of 466,311 prescriptions were entered in the period of 1 year. There were 3513 errors during this period (7.53 errors per 1000 prescriptions). More than half of these errors were made by the internal medicine specialty. In our study, 50% of the errors were severe errors (overdosing medications with narrow therapeutic index or over-riding allergies), 46.28% were moderate errors (overdosing, wrong dosing, duplicate orders, or prescribing multiple antibiotics), and 3.71% were not harmful errors (wrong dosing or incomplete orders). The errors were also categorized according to the class of medication. Errors in antibiotic prescription accounted for 53.9% of all errors. The pharmacist detected all these prescription errors as the prescriptions were reviewed in the CPOE system. Prescription errors are common medical errors seen in hospitals. The CPOE system has prevented and alerted the prescriber and pharmacist to dosage errors and allergies. Involvement of the pharmacist in reviewing the prescription and alerting the physician has minimized prescription errors to a great degree in our hospital setting. The incidence of prescription errors before the CPOE has been reported to range from 3 to 99 per 1000 prescriptions. The disparity could be due to

    Computerized provider order entry (CPOE) systems have been introduced to reduce medication errors, increase safety, improve work-flow efficiency, and increase medical service quality at the moment of prescription. Making the impact of CPOE systems more observable may facilitate their adoption by users. We set out to examine factors associated with the adoption of a CPOE system for inter-organizational and intra-organizational care. The diffusion of innovation theory was used to understand physicians' and nurses' attitudes and thoughts about implementation and use of the CPOE system. Two online survey questionnaires were distributed to all physicians and nurses using a CPOE system in county-wide healthcare organizations. The number of complete questionnaires analyzed was 134 from 200 nurses (67.0%) and 176 from 741 physicians (23.8%). Data were analyzed using descriptive-analytical statistical methods. More nurses (56.7%) than physicians (31.3%) stated that the CPOE system introduction had worked well in their clinical setting (P < 0.001). Similarly, more physicians (73.9%) than nurses (50.7%) reported that they found the system not adapted to their specific professional practice (P = < 0.001). Also more physicians (25.0%) than nurses (13.4%) stated that they did want to return to the previous system (P = 0.041). We found that in particular the received relative advantages of the CPOE system were estimated to be significantly (P < 0.001) higher among nurses (39.6%) than physicians (16.5%). However, physicians' agreements with the compatibility of the CPOE and with its complexity were significantly higher than the nurses (P < 0.001). Qualifications for CPOE adoption as defined by three attributes of diffusion of innovation theory were not satisfied in the study setting. CPOE systems are introduced as a response to the present limitations in paper-based systems. In consequence, user expectations are often high on their relative advantages as well as on a low level of

    Delcam, a manufacturing software developer, has supplied substantial funding towards a UK Government initiative intended to revolutionize the study of design and technology in schools. The computer-aided design software for schools (CAD-CAM) programme will give students a bridge into industry by enabling them to employ video links with engineers at companies such as British Aerospace and Rolls Royce. They will then be able to convert their virtual reality designs into a finished product. When the revised National Curriculum comes into effect this year, CAD-CAM will become compulsory from Key Stage 3, reflecting the greater focus on work-related learning, as well as the added importance being given to Information and Communications Technology (ICT) within the curriculum. Under the new scheme, schools can use a range of software designed in the UK (currently used for such items as jet aircraft and Formula One racing cars), which is being made available free of charge. The Design and Technology Association is monitoring the programme and the schools taking part have had to propose targets, focused on curriculum innovation, pupil outcomes and staff development. Still on the theme of design is the `Young Foresight' project launched in January and inviting 13 to 14 year-olds to tackle the challenges of the future through designing a new product for the world of 2020. The aim here is to encourage creativity, enterprise and innovation among young people by giving them an idea of what is involved in the design and development of a successful product. The students will be supported by mentors drawn from the local business community and there will be related BBC schools television programmes early in March with classroom resources, teacher training and an interactive website. The first phase of the initiative, based on 100 schools from across England and Wales, should be completed by autumn 2000, with phase 2 for 3000 schools over a three-year period incorporating a further

  1. Identification of Entry Factors Involved in Hepatitis C Virus Infection Based on Host-Mimicking Short Linear Motifs

    PubMed Central

    2017-01-01

    Host factors that facilitate viral entry into cells can, in principle, be identified from a virus-host protein interaction network, but for most viruses information for such a network is limited. To help fill this void, we developed a bioinformatics approach and applied it to hepatitis C virus (HCV) infection, which is a current concern for global health. Using this approach, we identified short linear sequence motifs, conserved in the envelope proteins of HCV (E1/E2), that potentially can bind human proteins present on the surface of hepatocytes so as to construct an HCV (envelope)-host protein interaction network. Gene Ontology functional and KEGG pathway analyses showed that the identified host proteins are enriched in cell entry and carcinogenesis functionalities. The validity of our results is supported by much published experimental data. Our general approach should be useful when developing antiviral agents, particularly those that target virus-host interactions. PMID:28129350

    This study examined how intrinsic as well as perceived message features affect the extent to which online health news stories prompt audience selections and social retransmissions, and how news-sharing channels (e-mail vs. social media) shape what goes viral. The study analyzed actual behavioral data on audience viewing and sharing of New York Times health news articles, and associated article content and context data. News articles with high informational utility and positive sentiment invited more frequent selections and retransmissions. Articles were also more frequently selected when they presented controversial, emotionally evocative, and familiar content. Informational utility and novelty had stronger positive associations with e-mail-specific virality, while emotional evocativeness, content familiarity, and exemplification played a larger role in triggering social media-based retransmissions.

    Socios En Salud uses directly observed therapy to treat a majority of the multidrug-resistant tuberculosis in Peru. The nurses play an important role in this community-based model as the patients' primary care givers. Since nurses, rather than physicians, are involved in patients' daily care, we developed a nurse-order entry system to test whether such a system would improve the accuracy and quality of medication data. We compared regimen information from patient electronic medical records, paper charts and pharmacy records. After a two-month training period on the new system, we conducted the trial for 52 days in two of Lima's six geographic treatment areas, and re-reviewed the three sources of medication data. We measured the error rates after the trial period and found there was no significant difference in the control group's (Lima Este), error rate (8.6% vs. 6.9%, P=0.66) after the trial. The intervention group (Lima Callao), however, showed a significant drop in the error rate (17.4% vs. 3.1%, P=0.0074) after the same time interval. Additionally, the nurse expressed satisfaction with the order entry system and its ease of use. The decrease in error rates and user satisfaction regarding the system are promising measures of our order entry system's success.

    2016-01-01

    Delivering bad news is a stressful moment for both physicians and patients. The purpose of this investigation was to explore the patients' preferences and attitudes toward being informed about the bad news. This cross-sectional study was done on patients admitted to Imam Khomeini Hospital, Sari, Iran, from September 2014 to February 2015. Patient attitude regarding breaking bad news was evaluated using a reliable and valid questionnaire. 130 patients were evaluated (61.5% male, mean age = 46.21 ± 12.1 years). 118 (90.76%) participants believed that the patient himself/herself should be informed about the disease's condition. 120 (92.30%) preferred to hear the news from a skillful physician and 105 (80.76%) believed that emergency department is not a proper place for breaking bad news. Based on the results of the present study, most participants believed that the most experienced and skillful physician should inform them completely regarding their medical condition. At the same time they declared that, it is best to hear bad news in a calm and suitable place and time rather than emergency department or hospital corridors during teaching rounds.

    2011-01-01

    The Mars Science Laboratory will be the first Mars mission to attempt a guided entry with the objective of safely delivering the entry vehicle to a survivable parachute deploy state within 12.5 km of the pre-designated parachute deploy coordinates. The Entry Terminal Point Controller guidance algorithm is derived from the final phase Apollo Command Module guidance and, like Apollo, modulates the bank angle to control range based on deviations in range, altitude rate, and drag acceleration from a reference trajectory. For application to Mars landers which must make use of the tenuous Martian atmosphere, it is critical to balance the lift of the vehicle to minimize the range while still ensuring a safe deploy altitude. An overview of the process to generate optimized guidance settings is presented, discussing improvements made over the last nine years. Performance tradeoffs between ellipse size and deploy altitude will be presented, along with imposed constraints of entry acceleration and heating. Performance sensitivities to the bank reversal deadbands, heading alignment, attitude initialization error, and entry delivery errors are presented.

  10. What's unusual in online disease outbreak news?

    PubMed Central

    2010-01-01

    Background Accurate and timely detection of public health events of international concern is necessary to help support risk assessment and response and save lives. Novel event-based methods that use the World Wide Web as a signal source offer potential to extend health surveillance into areas where traditional indicator networks are lacking. In this paper we address the issue of systematically evaluating online health news to support automatic alerting using daily disease-country counts text mined from real world data using BioCaster. For 18 data sets produced by BioCaster, we compare 5 aberration detection algorithms (EARS C2, C3, W2, F-statistic and EWMA) for performance against expert moderated ProMED-mail postings. Results We report sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), mean alerts/100 days and F1, at 95% confidence interval (CI) for 287 ProMED-mail postings on 18 outbreaks across 14 countries over a 366 day period. Results indicate that W2 had the best F1 with a slight benefit for day of week effect over C2. In drill down analysis we indicate issues arising from the granular choice of country-level modeling, sudden drops in reporting due to day of week effects and reporting bias. Automatic alerting has been implemented in BioCaster available from http://born.nii.ac.jp. Conclusions Online health news alerts have the potential to enhance manual analytical methods by increasing throughput, timeliness and detection rates. Systematic evaluation of health news aberrations is necessary to push forward our understanding of the complex relationship between news report volumes and case numbers and to select the best performing features and algorithms.

    The article broaches the subject of breaking bad news. Medical doctors deal with such a problem frequently, not always well-prepared for their role. Obviously, each patient should be treated individually, not only because every disease is a unique case, but also because patients have their own hopes and expectations. In order to conduct a discussion containing bad news, it is worth to base on the scheme presented in the article. Preparation for the meeting is crucial. Besides the fact that it facilitates the dialogue, it also enables presenting information in the right way. Firstly, it is important to listen to the patient carefully, clarify his concerns and then answer all his questions and doubt. Next, if the patient is willing, the doctor should discuss the state of health, possible therapies and prognosis. The end of the talk should consist of appropriate summary and the date of the next meeting. The article emphasize that truth and reliability are extremely significant in contact with a patient. Moreover, it presents the area of information which can be talked about with the family. The authors try to approach the dialogue which contains bad news, reveal various possibility of conducting the discussion and dealing with problems.

    Cellular infection by HIV-1 is initiated with a binding event between the viral envelope glycoprotein gp120 and the cellular receptor protein CD4. The CD4-gp120 interface is dominated by two hotspots: a hydrophobic gp120 cavity capped by Phe43{sub CD4} and an electrostatic interaction between residues Arg59{sub CD4} and Asp368{sub gp120}. The CD4 mimetic small-molecule NBD-556 (1) binds within the gp120 cavity; however, 1 and related congeners demonstrate limited viral neutralization breadth. Herein, we report the design, synthesis, characterization, and X-ray structures of gp120 in complex with small molecules that simultaneously engage both binding hotspots. The compounds specifically inhibit viral infection of 42 tier 2 clades B and C viruses and are shown to be antagonists of entry into CD4-negative cells. Dual hotspot design thus provides both a means to enhance neutralization potency of HIV-1 entry inhibitors and a novel structural paradigm for inhibiting the CD4-gp120 protein-protein interaction.

    Inhibitors of viral entry are under consideration as topical microbicides to prevent HIV-1 sexual transmission. Small molecules targeting HIV-1 gp120 (BMS-378806) or CCR5 (CMPD167), and a peptide fusion inhibitor (C52L), each blocks vaginal infection of macaques by a SHIV. A microbicide, however, must be active against multiple HIV-1 variants. We therefore tested BMS-C (a BMS-378806 derivative), CMPD167, C52L and the CXCR4 ligand AMD3465, alone and in combination, against 25 primary R5, 12 X4 and 7 R5X4 isolates from subtypes A-G. At high concentrations (0.1-1 {mu}M), the replication of most R5 isolates in human donor lymphocytes was inhibited by > 90%. At lower concentrations, double and triple combinations were more effective than individual inhibitors. Similar results were obtained with X4 viruses when AMD3465 was substituted for CMPD167. The R5X4 viruses were inhibited by combining AMD3465 with CMPD167, or by the coreceptor-independent compounds. Thus, combining entry inhibitors may improve microbicide effectiveness.

    Objectives To design an assignment for second-professional year pharmacy students to assess the accuracy and quality of health information published in the news. Design Students in a literature evaluation course were assigned a health-related news publication to review and find the original published research article. They then critically evaluated the quality and accuracy of the news publication based on the original research. All students wrote a critique focusing on the quality and accuracy of the news article and potential responses the lay public might have. Assessment Eighty-four percent of students agreed the writing assignment reinforced critical literature evaluation skills, while 90% agreed the assignment contributed to completion of course objectives. Conclusions A writing assignment requiring comparison of a news publication to the original research reinforces critical literature evaluation and communication skills, as well as stimulates thought about the accuracy, quality, and public responses to health information published in the news.

    2017-02-01

    In an attempt to qualify changes to science news reporting due to the impact of the Internet, we studied all science news articles published in Danish national newspapers in a November week in 1999 and 2012, respectively. We find the same amount of science coverage, about 4% of the total news production, in both years, although the tabloids produce more science news in 2012. Online science news also received high priority. Journalists in 2012 more often than in 1999 make reference to scientific journals and cite a wider range of journals. Science news in 2012 is more international and politically oriented than in 1999. Based on these findings, we suggest that science news, due partly to the emergence of online resources, is becoming more diverse and available to a wider audience. Science news is no longer for the elite but has spread to virtually everywhere in the national news system.

    In the UK, men's alcohol-related morbidity and mortality still greatly exceeds women's, despite an increase in women's alcohol consumption in recent decades. New UK alcohol guidelines introduce gender-neutral low-risk alcohol consumption guidance. This study explores how UK newspaper and online news represent women's and men's 'binge' drinking to identify opportunities to better align reporting of harmful drinking with evidence. Quantitative and qualitative content analysis of 308 articles published in 7 UK national newspapers and the BBC News website between 1 January 2012 and 31 December 2013. Articles associated women with 'binge' drinking more frequently than men, and presented women's drinking as more problematic. Men were more frequently characterised as violent or disorderly, while women were characterised as out of control, putting themselves in danger, harming their physical appearance and burdening men. Descriptions of female 'binge' drinkers' clothing and appearance were typically moralistic. The UK news media's disproportionate focus on women's 'binge' drinking is at odds with epidemiological evidence, may reproduce harmful gender stereotypes and may obstruct public understandings of the gender-neutral weekly consumption limits in newly proposed alcohol guidelines. In order to better align reporting of harmful drinking with current evidence, public health advocates may engage with the media with a view to shifting media framing of 'binge' drinking away from specific groups (young people; women) and contexts (public drinking) and towards the health risks of specific drinking behaviours, which affect all groups regardless of context.

    An overview of the reconstruction analyses performed for the Stardust capsule entry is described. The results indicate that the actual entry was very close to the pre-entry predictions. The capsule landed 8.1 km north-northwest of the desired target at Utah Test and Training Range. Analyses of infrared video footage and radar range data (obtained from tracking stations) during the descent show that drogue parachute deployment was 4.8 s later than the pre-entry prediction, while main parachute deployment was 19.3 s earlier than the pre-set timer indicating that main deployment was actually triggered by the backup baroswitch. Reconstruction of a best estimated trajectory revealed that the aerodynamic drag experienced by the capsule during hypersonic flight was within 1% of pre-entry predications. Observations of the heatshield support the pre-entry estimates of small hypersonic angles of attack, since there was very little, if any, charring of the shoulder region or the aftbody. Through this investigation, an overall assertion can be made that all the data gathered from the Stardust capsule entry were consistent with flight performance close to nominal pre-entry predictions. Consequently, the design principles and methodologies utilized for the flight dynamics, aerodynamics, and aerothermodynamics analyses have been corroborated.

  9. MSL EDL Entry Guidance using the Entry Terminal Point Controller

    NASA Technical Reports Server (NTRS)

    2006-01-01

    The Mars Science Laboratory will be the first Mars mission to attempt a guided entry with the objective of safely delivering the entry vehicle to a survivable parachute deploy state within 10 km of the pre-designated landing site. The Entry Terminal Point Controller guidance algorithm is derived from the final phase Apollo Command Module guidance and, like Apollo, modulates the bank angle to control range based on deviations in range, altitude rate, and drag acceleration from a reference trajectory. For application to Mars landers which must make use of the tenuous Martian atmosphere, it is critical to balance the lift of the vehicle to minimize the range while still ensuring a safe deploy altitude. An overview of the process to generate optimized guidance settings is presented, discussing improvements made over the last four years. Performance tradeoffs between ellipse size and deploy altitude will be presented, along with imposed constraints of entry acceleration and heating. Performance sensitivities to the bank reversal deadbands, heading alignment, attitude initialization error, and atmospheric delivery errors are presented. Guidance settings for contingency operations, such as those appropriate for severe dust storm scenarios, are evaluated.

    2017-06-01

    Communication based on patient preferences can alleviate their psychological distress and is an important part of patient-centered care for physicians who have the task of conveying bad news to cancer patients. The present study aimed to explore the demographic, medical, and psychological factors associated with patient preferences with regard to communication of bad news. Outpatients with a variety of cancers were consecutively invited to participate in our study after their follow-up medical visit. A questionnaire assessed their preferences regarding the communication of bad news, covering four factors-(1) how bad news is delivered, (2) reassurance and emotional support, (3) additional information, and (4) setting-as well as on demographic, medical, and psychosocial factors. A total of 529 outpatients with a variety of cancers completed the questionnaire. Multiple regression analyses indicated that patients who were younger, female, had greater faith in their physician, and were more highly educated placed more importance on "how bad news is delivered" than patients who were older, male, had less faith in their physician, and a lower level of education. Female patients and patients without an occupation placed more importance on "reassurance and emotional support." Younger, female, and more highly educated patients placed more importance on "additional information." Younger, female, and more highly educated patients, along with patients who weren't undergoing active treatment placed more importance on "setting." Patient preferences with regard to communication of bad news are associated with factors related to patient background. Physicians should consider these characteristics when delivering bad news and use an appropriate communication style tailored to each patient.

  1. The impact of delivery style on doctors' experience of stress during simulated bad news consultations.

    Shaw, Joanne; Brown, Rhonda; Dunn, Stewart

    2015-10-01

    The purpose of this study was to investigate the relationship between doctors' bad news delivery style and their experience of physiological stress during simulated bad news consultations. 31 doctors participated in two simulated breaking bad news (BBN) consultations. Delivery style was categorized as either blunt, forecasting or stalling (i.e. avoidant), based on the time to deliver the bad news and qualitative analysis of the interaction content and doctor's language style. Doctors' heart rate (HR) and skin conductance (SC) were recorded in consecutive 30s epochs. Doctors experienced a significant decrease in HR (F(1,36)=44.9, p<.0001) and SC (F(1,48)=5.6, p<.001) between the pre- and post-news delivery phases of the consultation. Between-group comparisons for the three delivery styles did not identify any significant differences in HR (F(2,36)=2.2, p>.05) or SC (F(2,48)=.66, p>.05). Doctors experience heightened stress in the pre-news delivery phase of breaking bad news interactions. Delaying the delivery of bad news exposes doctors to a longer period of increased stress.This suggests that medical students and doctors should be taught to deliver bad news without delay, to help mitigate their response to this stressful encounter.

    The Multi-Mission Earth Entry Vehicle project is developing an integrated tool called Multi Mission System Analysis for Planetary Entry Descent and Landing that will provide key technology solutions including mass sizing, aerodynamics, aerothermodynamics, and thermal and structural analysis for any given sample return mission. Thermal soak analysis and temperature predictions of various components including the payload container of the entry vehicle are part of the solution that this tool will offer to mission designers. The present paper focuses on the thermal soak analysis of an entry vehicle design based on the Mars Sample Return entry vehicle geometry and discusses a technical approach to develop parametric models for thermal soak analysis that will be integrated into the tool.

  14. Equilibrium radiative heating tables for Earth entry

    Sutton, Kenneth; Hartung, Lin C.

    1990-01-01

    The recent resurgence of interest in blunt-body atmospheric entry for applications such as aeroassisted orbital transfer and planetary return has engendered a corresponding revival of interest in radiative heating. Radiative heating may be of importance in these blunt-body flows because of the highly energetic shock layer around the blunt nose. Sutton developed an inviscid, stagnation point, radiation coupled flow field code for investigating blunt-body atmospheric entry. The method has been compared with ground-based and flight data, and reasonable agreement has been found. To provide information for entry body studies in support of lunar and Mars return scenarios of interest in the 1970's, the code was exercised over a matrix of Earth entry conditions. Recently, this matrix was extended slightly to reflect entry vehicle designs of current interest. Complete results are presented.

  1. Localisation-based imaging of malarial antigens during erythrocyte entry reaffirms a role for AMA1 but not MTRAP in invasion

    PubMed Central

    Riglar, David T.; Whitehead, Lachlan; Cowman, Alan F.; Rogers, Kelly L.; Baum, Jake

    2016-01-01

    ABSTRACT Microscopy-based localisation of proteins during malaria parasite (Plasmodium) invasion of the erythrocyte is widely used for tentative assignment of protein function. To date, however, imaging has been limited by the rarity of invasion events and the poor resolution available, given the micron size of the parasite, which leads to a lack of quantitative measures for definitive localisation. Here, using computational image analysis we have attempted to assign relative protein localisation during invasion using wide-field deconvolution microscopy. By incorporating three-dimensional information we present a detailed assessment of known parasite effectors predicted to function during entry but as yet untested or for which data are equivocal. Our method, termed longitudinal intensity profiling, resolves confusion surrounding the localisation of apical membrane antigen 1 (AMA1) at the merozoite–erythrocyte junction and predicts that the merozoite thrombospondin-related anonymous protein (MTRAP) is unlikely to play a direct role in the mechanics of entry, an observation supported with additional biochemical evidence. This approach sets a benchmark for imaging of complex micron-scale events and cautions against simplistic interpretations of small numbers of representative images for the assignment of protein function or prioritisation of candidates as therapeutic targets.

    2017-04-19

    Watching news is important for preadolescents, but it may also harm their well-being. This study examined whether applying insights from positive psychology to news production can reduce this potential harm, by reducing negative emotional responses and enhancing positive emotional responses to negative news, and by encouraging prosocial intentions. Moreover, we explored whether peer discussion strengthened these effects. Preadolescents (n = 336; 9-13 years old; 48.5% female) were exposed to either constructive (solution-based news including positive emotions) or nonconstructive news. Subsequently, half of the children assigned to the constructive and the nonconstructive condition participated in a peer discussion. The findings showed that exposure to constructive news resulted in more positive emotional responses and less negative emotional responses as compared to nonconstructive news. Moreover, discussing the news with peers led to more positive and less negative emotional responses among preadolescents who watched the nonconstructive newscast, and to more prosocial intentions among preadolescents who watched constructive news. In all, constructive news reporting and peer discussion could function as tools to make negative news less harmful for preadolescents.

  3. a Reflective Perspective Towards Agricultural Information-Based System Development in General Rural China and Farmers' Economic Association as the Entry Point of Icts

    Ji, Miao; Zuo, Ting; Leninhan, Eamon

    The information-based agricultural system plays a profound role in agricultural economic and social development in long term. There are various practices worldwide, both successful and unsuccessful. In recent years new technologies blossomed, if those new technologies succeed in the developed world, does it hold true for China? The alternative choices in informationbased system development should be noticed in China. This article argues that China’s development policy should choose the way that adapts to China’s circumstances, not totally adopt the western way. In the current situation of general rural China, the theme of information-based agricultural system needs to be further addressed. It is suggested that the Farmers’ Economic Association can be considered as one of the most accessible entry-points for further development way.

  4. Fluorescence-based measurement of store-operated calcium entry in live cells: from cultured cancer cell to skeletal muscle fiber.

    PubMed

    Pan, Zui; Zhao, Xiaoli; Brotto, Marco

    2012-02-13

    Store operated Ca(2+) entry (SOCE), earlier termed capacitative Ca(2+) entry, is a tightly regulated mechanism for influx of extracellular Ca(2+) into cells to replenish depleted endoplasmic reticulum (ER) or sarcoplasmic reticulum (SR) Ca(2+) stores. Since Ca(2+) is a ubiquitous second messenger, it is not surprising to see that SOCE plays important roles in a variety of cellular processes, including proliferation, apoptosis, gene transcription and motility. Due to its wide occurrence in nearly all cell types, including epithelial cells and skeletal muscles, this pathway has received great interest. However, the heterogeneity of SOCE characteristics in different cell types and the physiological function are still not clear. The functional channel properties of SOCE can be revealed by patch-clamp studies, whereas a large body of knowledge about this pathway has been gained by fluorescence-based intracellular Ca(2+) measurements because of its convenience and feasibility for high-throughput screening. The objective of this report is to summarize a few fluorescence-based methods to measure the activation of SOCE in monolayer cells, suspended cells and muscle fibers. The most commonly used of these fluorescence methods is to directly monitor the dynamics of intracellular Ca(2+) using the ratio of F(340nm;) and F(380nm;) (510 nm for emission wavelength) of the ratiometric Ca(2+) indicator Fura-2. To isolate the activity of unidirectional SOCE from intracellular Ca(2+) release and Ca(2+) extrusion, a Mn(2+) quenching assay is frequently used. Mn(2+) is known to be able to permeate into cells via SOCE while it is impervious to the surface membrane extrusion processes or to ER uptake by Ca(2+) pumps due to its very high affinity with Fura-2. As a result, the quenching of Fura-2 fluorescence induced by the entry of extracellular Mn(2+) into the cells represents a measurement of activity of SOCE. Ratiometric measurement and the Mn(+2) quenching assays can be performed on a

  5. Ultrasmall Gold Nanoparticles as Carriers for Nucleus-Based Gene Therapy Due to Size-Dependent Nuclear Entry

    PubMed Central

    2015-01-01

    The aim of this study was to determine the size-dependent penetration ability of gold nanoparticles and the potential application of ultrasmall gold nanoparticles for intranucleus delivery and therapy. We synthesized gold nanoparticles with diameters of 2, 6, 10, and 16 nm and compared their intracellular distribution in MCF-7 breast cancer cells. Nanoparticles smaller than 10 nm (2 and 6 nm) could enter the nucleus, whereas larger ones (10 and 16 nm) were found only in the cytoplasm. We then investigated the possibility of using ultrasmall 2 nm nanoparticles as carriers for nuclear delivery of a triplex-forming oligonucleotide (TFO) that binds to the c-myc promoter. Compared to free TFO, the nanoparticle-conjugated TFO was more effective at reducing c-myc RNA and c-myc protein, which resulted in reduced cell viability. Our result demonstrated that the entry of gold nanoparticles into the cell nucleus is critically dependent on the size of the nanoparticles. We developed a strategy for regulating gene expression, by directly delivering TFOs into the nucleus using ultrasmall gold nanoparticles. More importantly, guidelines were provided to choose appropriate nanocarriers for different biomedical purposes. PMID:24824865

    2014-01-01

    Despite the benefits of computerized provider order entry (CPOE), numerous reports of unexpected CPOE-related safety concerns have surfaced. As part of a larger project to improve the safety of electronic health records (EHRs), we developed and field tested a CPOE "safety self-assessment" guide through literature searches, expert opinion, and site visits. We then conducted a field test of this guide with nine hospital chief medical informatics officers (CMIOs), who were identified through the Association of Medical Directors of Information Systems. The CPOE safety self-assessment guide was sent electronically to the CMIOs. Once the assessments were returned, we conducted structured telephone interviews for further comments about the guide's format and content. The CMIOs in our study found the CPOE safety guide useful and relatively easy to complete, taking no more than 30 minutes. Analysis of responses to the guide suggest that most recommended practices were implemented inconsistently across facilities. Despite consensus for certain CPOE best practices in the medical literature and among experts, there appeared to be considerable variation among CMIOs' opinions of best practices. Interview data suggested this inconsistency was mostly due to system limitations and/or differing opinions about the necessity of certain EHR-related safety measures. Despite the absence of consensus on best practices, a self-assessment safety guide provides a practical starting point for organizations to assess and improve safety and the effectiveness of their CPOE system.

    Research across different fields of psychology has reported effects of colour cues on a variety of cognitive processes. Especially, the colour red has been shown to have striking influences. In the context of media reception, however, colour effects have been widely neglected so far. This study made a first step in this direction by investigating the effects of the colour red (compared with blue and grey) on the way news articles are evaluated. Two types of news were framed by a coloured border while the valence of the news content additionally varied. Based on 369 participants who read and evaluated the news articles online, we observed effects for colour cues and news valence in the absence of an interaction effect, indicating that the colour red induced approach motivation. However, only the contrast between red and grey reached statistical significance, indicating that chromatic and achromatic colours may differ in their perceived visual saliency. Overall, these results provide an important complement to previous studies and have practical implications for media researchers and producers. © 2015 International Union of Psychological Science.

    Breaking bad news is one of doctors' duties and it requires them to have some skills, given that this situation is difficult and distressful for patients and their families. Moreover, it is also an uncomfortable condition for doctors. The aim of this study was to evaluate doctors' capacity to break bad news, ascertain which specialties are best prepared for doing this and assess the importance of including this topic within undergraduate courses. Observational cross-sectional quantitative study conducted at a university hospital in Belo Horizonte (MG), Brazil. This study used a questionnaire based on the SPIKES protocol, which was answered by 121 doctors at this university hospital. This questionnaire investigated their attitudes, posture, behavior and fears relating to breaking bad news. The majority of the doctors did not have problems regarding the concept of bad news. Nevertheless, their abilities diverged depending on the stage of the protocol and on their specialty and length of time since graduation. Generally, doctors who had graduated more than ten years before this survey felt more comfortable and confident, and thus transmitted the bad news in a better conducted manner. Much needs to be improved regarding this technique. Therefore, inclusion of this topic in undergraduate courses is necessary and proposals should be put forward and verified.

  12. Temporal and Cross Correlations in Business News

    Mizuno, T.; Takei, K.; Ohnishi, T.; Watanabe, T.

    We empirically investigate temporal and cross correlations inthe frequency of news reports on companies, using a dataset of more than 100 million news articles reported in English by around 500 press agencies worldwide for the period 2003--2009. Our first finding is that the frequency of news reports on a company does not follow a Poisson process, but instead exhibits long memory with a positive autocorrelation for longer than one year. The second finding is that there exist significant correlations in the frequency of news across companies. Specifically, on a daily time scale or longer the frequency of news is governed by external dynamics, while on a time scale of minutes it is governed by internal dynamics. These two findings indicate that the frequency of news reports on companies has statistical properties similar to trading volume or price volatility in stock markets, suggesting that the flow of information through company news plays an important role in price dynamics in stock markets.

  13. Orion Entry Monitor

    2016-01-01

    NASA is scheduled to launch the Orion spacecraft atop the Space Launch System on Exploration Mission 1 in late 2018. When Orion returns from its lunar sortie, it will encounter Earth's atmosphere with speeds in excess of 11 kilometers per second, and Orion will attempt its first precision-guided skip entry. A suite of flight software algorithms collectively called the Entry Monitor has been developed in order to enhance crew situational awareness and enable high levels of onboard autonomy. The Entry Monitor determines the vehicle capability footprint in real-time, provides manual piloting cues, evaluates landing target feasibility, predicts the ballistic instantaneous impact point, and provides intelligent recommendations for alternative landing sites if the primary landing site is not achievable. The primary engineering challenges of the Entry Monitor is in the algorithmic implementation in making a highly reliable, efficient set of algorithms suitable for onboard applications.

  14. Medical student satisfaction, coping and burnout in direct-entry versus graduate-entry programmes.

    There is ongoing debate regarding the optimal length of medical training, with concern about the cost of prolonged training. Two simultaneous tracks currently exist in Australia: direct entry from high school and graduate entry for students with a bachelor degree. Medical schools are switching to graduate entry based on maturity, academic preparedness and career-choice surety. We tested the assumption that graduate entry is better by exploring student preferences, coping, burnout, empathy and alcohol use. From a potential pool of 2188 participants, enrolled at five Australian medical schools, a convenience sample of 688 (31%) first and second year students completed a survey in the middle of the academic year. Participants answered questions about demographics, satisfaction and coping and completed three validated instruments. Over 90% of students preferred their own entry-type, though more graduate-entry students were satisfied with their programme (82.4% versus 65.3%, p < 0.001). There was no difference between graduate-entry and direct-entry students in self-reported coping or in the proportion of students meeting criteria for burnout (50.7% versus 51.2%). Direct-entry students rated significantly higher for empathy (concern, p = 0.022; personal distress, p = 0.031). Graduate-entry students reported significantly more alcohol use and hazardous drinking (30.0% versus 22.8%; p = 0.017). Our multi-institution data confirm that students are generally satisfied with their choice of entry pathway and do not confirm significant psychosocial benefits of graduate entry. Overall, our data suggest that direct-entry students cope with the workload and psychosocial challenges of medical school, in the first 2 years, as well as graduate-entry students. Burnout and alcohol use should be addressed in both pathways. Despite studies showing similar academic outcomes, and higher total costs, more programmes in Australia are becoming graduate entry.

    Computerized physician order entry (CPOE) applications are widely used to prevent medical errors. In our center, a CPOE system has been in use since 2009 on both the inpatient and outpatient levels. A new and simple alert was introduced in the CPOE system to notify healthcare providers of the potential risk of viral reactivation when prescribing biological therapies, thereby facilitating the request for a serological profile (hepatitis B surface antigen [HBsAg], anti-HBc, and anti-HBs) in patients who have not had these tests. Between May 2012 and May 2013, a total of 1,076 patients undergoing biological treatment were included in the implementation of the CPOE in our hospital, resulting in the identification of 4 HBsAg-positive and 69 anti-HBc-positive/HBsAg-negative patients, two of them with positive viral loads. Since the implementation of this alert system, over 90% of patients who were prescribed a biological drug (BD) have undergone serological screening to detect hepatitis B virus (HBV) infection. The use of the alert system has increased the screening rate from less than 50% to 94% for HBsAg and from less than 30% to 85% for anti-HBc in patients for whom a BD is prescribed. Six patients received prophylactic antiviral therapy. No patient had HBV reactivation. This study demonstrates the feasibility of implementing a CPOE system that has allowed our hospital to increase the rate of HBV screening. Its use has facilitated the identification of patients at high risk for HBV reactivation and permitted physicians to prescribe prophylactic measures according to current guidelines. © 2014 by the American Association for the Study of Liver Diseases.

    A new code for the simulation of full (forebody and base region) flowfields about bluff bodies in the hypersonic regime of severe planetary entry is described. The present 'maximally conservative, maximally differenced' formulation of the unsteady compressible Navier-Stokes equations for 2-D axisymmetric 3-D flow is contrasted for stability with previous formulations of Viviand, Kutler, et al, and Thomas and Lombard. Discrete metric relations peculiar to the axisymmetric finite volume formulation are presented along with a general discussion of their relations to and consequences of failure to close computational cells. A computational mesh of curvilinear coordinate topology singular in the flow regime is presented that permits aligned capturing of the major physical features of the complex flowfield.

    A survey of 20 clinical informaticists with experience in implementing Computer-based Provider Order Entry (CPOE) systems revealed the lack of easily accessible measurements of success. Using a Delphi approach, the authors, together with a group of CPOE experts, selected eight key CPOE-related measures to assess system availability, use, benefits, and e-Iatrogenesis. We suggest collecting these measures on a widespread/national basis would be wise stewardship and result in tighter feedback about both clinician workflow and patient safety. Establishing reliable benchmarks against which new implementations and existing systems can be compared will enhance organizations' ability to effectively manage and hence to realize the full benefits of their CPOE implementations.

    This report summarizes results of research sponsored by the US Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory Research to initiate the use of the Systems Approach to Training in the evaluation of training programs and entry level qualifications for nuclear power plant (NPP) personnel. Variables (performance shaping factors) of potential importance to personnel selection and training are identified, and research to more rigorously define an operationally useful taxonomy of those variables is recommended. A high-level model of the Systems Approach to Training for use in the nuclear industry, which could serve as a model for NRC evaluation of industry programs, is presented. The model is consistent with current publically stated NRC policy, with the approach being followed by the Institute for Nuclear Power Operations, and with current training technology. Checklists to be used by NRC evaluators to assess training programs for NPP control-room personnel are proposed which are based on this model.

    2012-08-01

    To determine the efficacy of using media releases for tobacco control advocacy in Australia's advanced policy environment. Between February and August 2010, news releases that summarised either newly published but unpublicized research findings, or local developments in tobacco control, were sent to NSW media outlets. Reports arising from the releases were tracked using commercial services Media Monitors and Factiva, as well as Google and Google News. Other tobacco control related news items during the same period were also tracked and recorded. Twenty-one news releases generated 93 news items across all news media, with a quarter of these related to a story of porcine haemoglobin in cigarette filters. By comparison, 'live' policy issues (especially plain packaging and a significant tobacco tax increase) covered in this period attracted 1,033 news stories in the Australian media. Press releases describing recently published, but underpublicized research were issued in weeks where no major competing tobacco control news occurred. Results of this project indicate that in environments with advanced tobacco policy, media opportunities related to tobacco control advocacy are limited, as many objectives have been achieved. The media can still play a key advocacy role in such environments, and advocates need to be particularly vigilant for opportunities that do arise. The paper also highlights the increasingly important role of internet-based media, including opportunities presented by social media for tobacco control.

    The Ebola outbreak of 2014-2015 raised concerns about the disease's potential spread in the U.S. and received significant news media coverage. Prior research has shown that news media coverage of policy options can influence public opinion regarding those policies, as well as public attitudes toward the broader social issues and target populations addressed by such policies. To assess news media coverage of Ebola policies, the content of U.S.-focused news stories (n=1262) published between July 1 and November 30, 2014 from 12 news sources was analyzed for 13 policy-related messages. Eight-two percent of news stories mentioned one or more policy-related messages. The most frequently appearing policy-related messages overall were those about isolation (47%) and quarantine (40%). The least frequently mentioned policy-related message described dividing potentially exposed persons into distinct groups based on their level of Ebola risk in order to set different levels of restrictions (5%). Message frequency differed depending on whether news sources were located in an area that experienced an Ebola case or controversy, by news sources' political ideological perspective, and by type of news source (print and television). All policy-related messages showed significant increases in frequency after the first case of Ebola was diagnosed in the U.S. on September 30, 2014, with the exception of messages related to isolation, which showed a significant decrease. Results offer insight into how the news media covers policies to manage emerging disease threats.

    The manner in which healthcare professionals deliver bad news affects the way it is received, interpreted, understood, and dealt with. Despite the fact that clinicians are responsible for breaking bad news, it has been shown that they lack skills necessary to perform this task. The purpose of this study was to explore Iranian mothers' experiences to receive bad news about their children cancer and to summarize suggestions for improving delivering bad news by healthcare providers. A qualitative approach using content analysis was adopted. Semi-structured interviews were conducted with 14 mothers from two pediatric hospitals in Iran. Five major categories emerged from the data analysis, including dumping information, shock and upset, emotional work, burden of delivering bad news to the family members, and a room for multidisciplinary approach. Effective communication of healthcare team with mothers is required during breaking bad news. Using multidisciplinary approaches to prevent harmful reactions and providing appropriate support are recommended.

    Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

    acceleration guidance approach successfully used in missions like the Space Shuttle. Based on this approach, a new planner has been developed that is computationally fast and provides trajectories with both high final altitude and high control authority. A new tracking law based on nonlinear predictive control has been developed to track the reference trajectory. The new tracking law accounts for control saturation, which is a common feature of trajectories in the thin Martian atmosphere with a low lift vehicle. Finally, a final position guidance algorithm that aligns the vehicle's heading towards the target and provides altitude and range control, has been developed. The new guidance algorithm provides increased accuracy as well as higher final altitude compared to an entry guidance algorithm representative of the current capabilities.

    The Time Card Entry System was developed to interface with the DOE Headquarters Electronic Time and Attendance (ETA) system. It features pop-up window pick lists for Work Breakdown Structure Numbers and Hour Codes and has extensive processing that ensures that time and attendance reported by the employee fulfills US Government/OMB requirements before Timekeepers process the data at the end of the two week payroll cycle using ETA. Tours of Duty (e.g. ten hour day, four day week with Friday through Sunday off), established in the ETA system, are imported into the Time Card Entry System by the Timekeepers. An individual`s Tour of Duty establishes the basis for validation of time of day and number of hours worked per day. At the end of the two week cycle, data is exported by the Timekeepers from the Time Card Entry System into ETA data files.

    The challenge in the definition of the entry aerothermodynamic environment arising from the challenge of a reliable and reusable Orbiter is reviewed in light of the existing technology. Select problems pertinent to the orbiter development are discussed with reference to comprehensive treatments. These problems include boundary layer transition, leeward-side heating, shock/shock interaction scaling, tile gap heating, and nonequilibrium effects such as surface catalysis. Sample measurements obtained from test flights of the Orbiter are presented with comparison to preflight expectations. Numerical and wind tunnel simulations gave efficient information for defining the entry environment and an adequate level of preflight confidence. The high quality flight data provide an opportunity to refine the operational capability of the orbiter and serve as a benchmark both for the development of aerothermodynamic technology and for use in meeting future entry heating challenges.

    The purpose of this review is to summarize the key findings which prove that the biased perceptions of viewers may provide an inaccurate image of the informational validity of televised news. The news may generate distorted recollections of what occurred in particular reported events if displayed routines influence viewers not to pay attention to the essential features of a narrative. Elaborating on Fiske and Hartley (2010), Zelizer (2010), and Gunter (2015), we indicate that the character of the news setting has altered and individuals’ news consumption routines have changed in adapting to media advancements. The news may be undergone at various psychological stages by news publics. Televised news may transmit information undeviatingly to publics that may (not) be committed successfully to memory. Our paper shows that individuals’ skills to handle information that is displayed in a linguistic configuration are influenced by their abilities in the utilization of certain symbol systems that are employed to represent notions and meanings. Televised news may shape what individuals grasp, influence their perceptions, convictions, and views regarding prevailing events and matters, and transmit knowledge and interpretation. If news stories can be jotted down in a linguistic style that sidesteps making needless processing demands and captivate news users by facilitating them to make connections with former knowledge, they may be more worthy of note and more edifying. We conclude that news narratives present a cognitive demanding task to individuals, displaying novel information regarding evolving events in a multifarious format. Broadcast news exhibits intricate contents, displaying configurations that employ excessively the cognitive abilities for information processing of viewers. PMID:28740475

    ABSTRACT OBJECTIVE To identify and quantify the reasons general practitioners and family physicians consider retraining and their reasons for not pursuing further training. DESIGN Population-based mailed survey. SETTING British Columbia. PARTICIPANTS Family physicians and general practitioners identified by the College of Physicians and Surgeons of British Columbia. MAIN OUTCOME MEASURES Practising physicians’ level of awareness of the University of British Columbia’s re-entry training program, the number and demographic characteristics of those who had considered retraining, their specialties of interest, and the barriers and possible inducements to retraining. RESULTS Only half of the survey respondents were aware of the re-entry training program at the University of British Columbia. A small but substantial number of practising general practitioners and family physicians were interested in taking specialty training from the Royal College of Physicians and Surgeons of Canada. While several training programs were particularly popular (ie, anesthesia and psychiatry—18.5% of respondents for each), almost every specialty training program was mentioned. Physicians identified the length and hours of training, financial issues, family issues, and the need for relocation as obstacles to retraining. The availability of part-time training, regional training, and return-of-service financial assistance were all identified as potential inducements. CONCLUSION To meet the needs of practising physicians, re-entry training programs will need to consider flexibility, where feasible, with regard to choice of specialty, intensity, and location of postgraduate training.

    Unified collision operator demonstrated for both radiation transport and PIC-DSMC. A side-by-side comparison between the DSMC method and the radiation transport method was conducted for photon attenuation in the atmosphere over 2 kilometers in physical distance with a reduction of photon density of six orders of magnitude. Both DSMC and traditional radiation transport agreed with theory to two digits. This indicates that PIC-DSMC operators can be unified with the radiation transport collision operators into a single code base and that physics kernels can remain unique to the actual collision pairs. This simulation example provides an initial validation of the unified collision theory approach that will later be implemented into EMPIRE.

    2003-01-01

    Because both computerized physician order entry (CPOE) systems and mobile technologies such as handheld devices have the potential to greatly impact the industry's future, IT vendors, hospitals, and clinicians are simply merging them into a logical convergence--"CPOE on a handheld"--with an expectation of full functionality on all platforms: computer workstations, rolling laptops, tablet PCs, and handheld devices. For these trends to succeed together, however, this expectation must be revised to establish a distinct category--mobile physician order entry (MPOE)--that is different from CPOE in form, function, and implementation.

    2016-05-01

    In the field of direct Dark Matter search a different and promising approach is the directionality: the observation of the incoming apparent direction of WIMPs would in fact provide a new and unambiguous signature. The NEWS project is a very innovative approach for a high sensitivity experiment aiming at the directional detection of WIMPs: the detector is based on a novel emulsion technology called NIT (Nano Imaging Trackers) acting both as target and tracking device. In this paper we illustrate the features of a NIT-based detector and the newly developed read-out systems allowing to reach a spatial resolution of the order of 10 nm. We present the background studies and the experimental design. Finally we report about the time schedule of the experiment and the expected sensitivity for DM searches.

    The effects of the built environment on walking in seniors have not been studied in an Asian context. To examine these effects, valid and reliable measures are needed. The aim of this study was to develop and validate a questionnaire of perceived neighborhood characteristics related to walking appropriate for Chinese seniors (Neighborhood Environment Walkability Scale for Chinese Seniors, NEWS-CS). It was based on the Neighborhood Environment Walkability Scale - Abbreviated (NEWS-A), a validated measure of perceived built environment developed in the USA for adults. A secondary study aim was to establish the generalizability of the NEWS-A to an Asian high-density urban context and a different age group. A multidisciplinary panel of experts adapted the original NEWS-A to reflect the built environment of Hong Kong and needs of seniors. The translated instrument was pre-tested on a sample of 50 Chinese-speaking senior residents (65+ years). The final version of the NEWS-CS was interviewer-administered to 484 seniors residing in four selected Hong Kong districts varying in walkability and socio-economic status. Ninety-two participants completed the questionnaire on two separate occasions, 2-3 weeks apart. Test-rest reliability indices were estimated for each item and subscale of the NEWS-CS. Confirmatory factor analysis was used to develop the measurement model of the NEWS-CS and cross-validate that of the NEWS-A. The final version of the NEWS-CS consisted of 14 subscales and four single items (76 items). Test-retest reliability was moderate to good (ICC > 50 or % agreement > 60) except for four items measuring distance to destinations. The originally-proposed measurement models of the NEWS-A and NEWS-CS required 2-3 theoretically-justifiable modifications to fit the data well. The NEWS-CS possesses sufficient levels of reliability and factorial validity to be used for measuring perceived neighborhood environment in Chinese seniors. Further work is needed to assess its

  1. News and the overloaded consumer: factors influencing information overload among news consumers.

    PubMed

    Holton, Avery E; Chyi, Hsiang Iris

    2012-11-01

    News producers continue to increase their volume of production and delivery platforms in an effort to reach and maintain news consumers. However, consumers may not necessarily find more news desirable. Previous studies have suggested that information surplus can lead to negative outcomes for consumers, but research of outcomes related to news production and consumption has been scant. This study explores novel areas of news surplus and overload, empirically examining factors associated with the degree of perceived overload across a broad spectrum of news delivery platforms. The findings reveal that the majority of today's news consumers feel overloaded with the amount of news they are confronted with. Gender, news interest, and the use of specific news platforms and outlets predict the degree of that overload. News access through platforms and outlets such as computers, e-readers, and Facebook is positively associated with overload, whereas other platforms such as television and the iPhone are negatively associated with overload. Implications for media psychology and news consumption are discussed.

    1975-01-01

    The feasibility of a Jovian entry by a probe originally designed for Saturn and Uranus entries is examined. An entry probe is described which is capable of release near an outer planet's sphere of influence and descent to a predetermined target entry point in the planet's atmosphere. The probe is designed so as to survive the trapped particle radiation belts and an entry heating pulse. Data is gathered and relayed to an overflying spacecraft bus during descent. Probe variations for two similar missions are described. In the first flyby of Jupiter by a Pioneer spacecraft launched during the 1979 opportunity is examined parametrically. In the second mission an orbiter based on Pioneer and launched in 1980 is defined in specific terms. The differences rest in the science payloads and directly affected wiring and electronics packages.

  5. [News in cystic fibrosis].

    PubMed

    Delaisi, B

    2013-08-01

    The improvement over the last two decades in the treatment of cystic fibrosis led to an increase in life expectancy approaching 40 years at birth. Logically, the population of adult patients has been increasing and is currently 50% of patients followed in France. These therapeutic advances have justified the establishment in 2003 of a generalized neonatal screening for cystic fibrosis. The latest data of this screening show an incidence of CF of 1/5359 live births, far below the incidence of 1/2500 which was widely accepted twenty years ago. The performance of this screening is currently based on the dosage of trypsin immuno reactive, followed in case of exceeding the threshold of a search of the 30 most common mutations, can detect around 96% of 150 to 200 CF cases every year. Therefore, the possibility of a false negative of the screening cannot be excluded and evocative symptoms of cystic fibrosis, even for children born after 2003, will lead to prescribe a sweat test. While treatments available so far goal consequences of cystic fibrosis, a new therapeutic class to correct the functional defect of the mutated protein, called CFTR modulators, is emerging. Ivacaftor, leader of this new class, belonging to the category of "CFTR potentiator" got its access on the market in September 2012 for patients carrying the G551D mutation. New other molecules, named "CFTR correctors" which can have synergistic effect with ivacaftor and concern patients carrying the most common mutation--DF 508--are under development. Copyright © 2013.

  6. Models of radon entry: A review

    SciTech Connect

    Gadgil, A.J.

    1991-08-01

    This paper reviews existing models of radon entry into houses. The primary mechanism of radon entry in houses with high indoor concentrations is, in most cases, convective entry of radon bearing soil-gas from the surrounding soil. The driving force for this convective entry is the small indoor-outdoor pressure difference arising from the stack effect and other causes. Entry points for the soil-gas generally are the cracks or gaps in the building substructure, or though other parts of the building shell in direct contact with the soil, although entry may also occur by flow though permeable concrete or cinder block walls of the substructure. Models using analytical solutions to idealized geometrical configurations with simplified boundary conditions obtain analytical tractability of equations to be solved at the cost of severe approximations; their strength is in the insights they offer with their solutions. Models based on lumped parameters attempt to characterize the significant physical behavioral characteristics of the soil-gas and radon flow. When realistic approximations are desired for the boundary conditions and terms in the governing equations, numerical models must be used; these are usually based on finite difference or finite element solutions to the governing equations. Limited data are now available for experimental verification of model predictions. The models are briefly reviewed and their strengths and limitations are discussed.

    and thought-provoking. Often these presentations have evolved, and at each stage their goal is to be able to accomplish the same demonstration with ever-simpler equipment. Given that we all live under financial constraints, the `third eye' refers to the ability to look around and find a useful piece of a demonstration apparatus amongst what others might perceive to be junk. All in all, it was a very stimulating and interesting presentation, and one can easily see why this group tours China to the rave reviews of the students there. As is true every year, the wealth of interesting and valuable work shared in the parallel sessions of contributed papers was astounding. As always, I found myself running from building to building in an attempt to hear as many talks as I could possibly attend. Often a colleague and I would split up to hear different talks, and then share what we'd learned over a meal later in the day. What follows are a few highlights of what we heard and saw in some of those sessions. As one would expect given the trend of recent years, there were many interesting talks about the incorporation of computers and instructional media in introductory physics teaching. Paris Naik from the University of Illinois presented a paper on their web-based Interactive Examples. These are very well thought-out homework problems that provide interactive help in the spirit of a Socratic dialogue. They can be viewed at webug.physics.uiuc.edu/courses/ie.html. Mario Belloni and Wolfgang Christian, both from Davidson College, each gave a talk on the use of Physlets, scriptable Java-based interactive physics problems. These can be sampled at webphysics.davidson.edu/physletprob. Ruth Chabay from Carnegie Mellon University presented the Visual Python real-time, three-dimensional graphics environment in which their first-year students are programming their own visualization of physical phenomena.

    Among the initiatives to be found at UK universities is a vocational award with the title `University Foundation Degree' at Nottingham Trent University. This qualification will be offered in 14 different subjects including four in the Faculty of Science and Mathematics, in the areas of applied biology, applied sciences, chemistry and physics. The courses will be available on a two-year full-time, three-year sandwich or a part-time basis. Set at a higher standard and specification than the Higher National Diplomas which it replaces, the UFD has been devised in consultation with industry and will cover the technical and specialist areas demanded by employers to combat skills shortages. The UFD in applied sciences concentrates on practical applications through laboratory, IT and project work, supported by lectures and seminars. At the end students can enter the employment market or transfer onto the second year of a degree course. Science-based careers including research and development would be the aim of those taking the UFD in physics. The first year develops the fundamentals of modern physics supported by studies in mathematics, IT and computer programming, whilst year 2 is vocational in nature with industrial problem solving and work experience as well as an academic theme associated with environmental aspects of the subject. Those who complete the UFD will be allowed automatic progression to a specified honours degree course and would normally be expected to study for a further two years for this award. However, those demonstrating an outstanding academic performance can transfer to the linked degree programme at the end of the first year via fast-track modules. Back in May the UK's Quality Assurance Agency (QAA) announced new standard benchmarks for degrees. These will be introduced into higher education institutions from 2002 to outline the knowledge, understanding and skills a student should gain from a particular higher education course.

The experiment is designed to throw light on the puzzling question of why there is so little antimatter in the universe and so much matter. The TRUMP BaBar resource package brings the mystery of antimatter into schools. There are notes and colourful posters on the physics of BaBar, and photocopiable sheets supporting student activities. These include explorations of symmetry, templates for making a scale model of the BaBar detector, and a web-based research project. The pack is designed mainly for A-level physics (particularly those courses that include some particle physics) but parts also relate to GCSE science, Scottish Higher physics and Standard physics. The BaBar resource package is available free from the Particle Physics and Astronomy Research Council, which fully funded its development and production.

    Entering the atmosphere of celestial bodies, spacecrafts encounter gases at velocities of several km/s, thereby being subjected to great heat loads. The thermal protection systems and the environment (plasma) have to be investigated by means of computational and ground facility based simulations. For more than a decade, plasma wind tunnels at IRS have been used for the investigation of TPS materials. Nevertheless, ground tests and computer simulations cannot re- place space flights completely. Particularly, entry mission phases encounter challenging problems, such as hypersonic aerothermodynamics. Concerning the TPS, radiation-cooled materials used for reuseable spacecrafts and ablator tech- nologies are of importance. Besides the mentioned technologies, there is the goal to manage guidance navigation, con- trol, landing technology and inflatable technologies such as ballutes that aim to keep vehicles in the atmosphere without landing. The requirement to save mass and energy for planned interplanetary missions such as Mars Society Balloon Mission, Mars Sample Return Mission, Mars Express or Venus Sample Return mission led to the need for manoeuvres like aerocapture, aero-breaking and hyperbolic entries. All three are characterized by very high kinetic vehicle energies to be dissipated by the manoeuvre. In this field flight data are rare. The importance of these manoeuvres and the need to increase the knowledge of required TPS designs and behavior during such mission phases point out the need of flight experiments. As result of the experience within the plasma diagnostic tool development and the plasma wind tunnel data base, flight experiments like the PYrometric RE-entry EXperiment PYREX were developed, fully qualified and successfully flown. Flight experiments such as the entry spectrometer RESPECT and PYREX on HOPE-X are in the conceptual phase. To increase knowledge in the scope of atmospheric manoeuvres and entries, data bases have to be created combining both

    2000-12-01

    In this paper we present a system for automated analysis, classification and indexing of broadcast news programs. The system first analyses the visual and the speech stream of an input news program in order to obtain an initial partitioning of the program into the so-called report segments. The analysis of the visual stream provides the boundaries of the report segments lying at the beginning and the end of each anchorperson shot. This analysis step is performed by applying an existing techniques for anchorperson shot detection. The analysis of the speech stream gives the boundaries of the report segments lying in the middle of each silent interval. Then, the transcribed speech of each of the report segments is matched with the content of a large pre-specified textual topic database. This database covers a large number of topics and can be updated by the user at any time. Fro each topic a vast number of keywords is given, each of which is also assigned a weight that indicates the importance of a keyword for a certain topic. The result of the matching procedure is a list of probable topics per report segment, where for each topic on the list a likelihood is computed based on the number of relevant keywords found in the segment and on the weights of those keywords. The list of topics per segment is then shortened by separating the most probable from least probable topics based on their likelihood. Finally, the likelihood values of the most probable topics are used in the last system module to merge related neighboring segments into reports. The most probable topics serving as the base for the segment-merging procedure are the same time the retrieval indexes for the reports and are used for classifying together all reports in the database that cover one and the same topic.

    Classroom Activities Mean Teamwork As much as any other facet of the editing and production of the Journal, the Classroom Activity series means teamwork! The aim is for activities to be interesting and accessible to introductory students, based on inexpensive and readily available materials, connected by content to some part of the Journal issue, able to be integrated into the high school curriculum, and safe. There need to be questions posed and answers at the ready. Additional information in print and on the Web needs to be identified and checked. The activities are designed to be ready for teachers to hand to students, so they really need to work-that means that they go through a lot of testing in Journal House where there is, quite fittingly, no lab. This is a tall order, one requiring someone with experience in high school teaching. From the start of the Activities in September 1997, Nancy Gettys has had a major role in their success. While Nancy's primary responsibility is as the Technical Editor of JCE Software, she has experience in teaching high school and has called on that experience to try and test, expand, try again, plan the illustrations (remember the photographs of the activities with surface phenomena that were featured in the table of contents of the February 1998 issue?), and perhaps hardest of all-tell us when something will just not work in high school. Nancy continues to work with the Classroom Activities, but she now has a colleague in fellow high school teacher Erica Jacobsen who has recently joined our staff. Introducing... Erica Jacobsen joined our staff last fall as an editorial assistant and has recently become an assistant editor. She received her undergraduate degree in education from the University of Wisconsin-Madison. Her teaching licenses include certifications in chemistry, physics, biology, and

    Current approaches lying in the intersection of computer vision and NLP have achieved unprecedented breakthroughs in tasks like automatic captioning or image retrieval. Most of these methods, though, rely on training sets of images associated with annotations that specifically describe the visual content. This paper proposes going a step further and explores more complex cases where textual descriptions are loosely related to images. We focus on the particular domain of News. We introduce new deep learning methods that address source and popularity prediction, article illustration, and article geolocation. An adaptive CNN is proposed, that shares most of the structure for all tasks, and is suitable for multitask and transfer learning. Deep CCA is deployed for article illustration, and a new loss function based on Great Circle Distance is proposed for geolocation. Furthermore, we present BreakingNews, a novel dataset with approximately 100K news articles including images, text, captions, and enriched with heterogeneous meta-data. BreakingNews allows exploring all aforementioned problems, for which we provide baseline performances using various CNN architectures, and different representations of the textual and visual features. We report promising results and bring to light several limitations of current state-of-the-art, which we hope will help spur progress in the field.

    Description After HIV diagnosis, timely entry into HIV medical care and retention in that care are essential to the provision of effective antiretroviral therapy (ART). ART adherence is among the key determinants of successful HIV treatment outcome and is essential to minimize the emergence of drug resistance. The International Association of Physicians in AIDS Care convened a panel to develop evidence-based recommendations to optimize entry into and retention in care and ART adherence for people with HIV. Methods A systematic literature search was conducted to produce an evidence base restricted to randomized, controlled trials and observational studies with comparators that had at least 1 measured biological or behavioral end point. A total of 325 studies met the criteria. Two reviewers independently extracted and coded data from each study using a standardized data extraction form. Panel members drafted recommendations based on the body of evidence for each method or intervention and then graded the overall quality of the body of evidence and the strength for each recommendation. Recommendations Recommendations are provided for monitoring of entry into and retention in care, interventions to improve entry and retention, and monitoring of and interventions to improve ART adherence. Recommendations cover ART strategies, adherence tools, education and counseling, and health system and service delivery interventions. In addition, they cover specific issues pertaining to pregnant women, incarcerated individuals, homeless and marginally housed individuals, and children and adolescents, as well as substance use and mental health disorders. Recommendations for future research in all areas are also provided. PMID:22393036
