  1. Topological Photonics for Continuous Media

    Silveirinha, Mario

    Photonic crystals have revolutionized light-based technologies during the last three decades. Notably, it was recently discovered that the light propagation in photonic crystals may depend on some topological characteristics determined by the manner how the light states are mutually entangled. The usual topological classification of photonic crystals explores the fact that these structures are periodic. The periodicity is essential to ensure that the underlying wave vector space is a closed surface with no boundary. In this talk, we prove that it is possible calculate Chern invariants for a wide class of continuous bianisotropic electromagnetic media with no intrinsic periodicity. The nontrivial topology of the relevant continuous materials is linked with the emergence of edge states. Moreover, we will demonstrate that continuous photonic media with the time-reversal symmetry can be topologically characterized by a Z2 integer. This novel classification extends for the first time the theory of electronic topological insulators to a wide range of photonic platforms, and is expected to have an impact in the design of novel photonic systems that enable a topologically protected transport of optical energy.

    Continuity models of midwifery care improve women's experiences of care and clinical outcomes, but organisationally driven working practices do not facilitate a continuity model and the midwifery care received by most women is fragmented (Sandall et al., 2016, NHS England, 2016). Little is known about the potential for continuity of midwifery care to be achieved using an electronic platform. This paper examines the experiences of women accessing known midwives through a social media platform and their experiences and perception of continuity of care. The study forms part of a larger research project aiming to increase understanding about online social learning within professionally moderated social media based communities. This paper reports specifically the concept of midwifery continuity within the online communities. Two secret Facebook groups consisting of 31 mothers and 4 midwife moderators were created (17 mothers & 2 midwives / 14 mothers & 2 midwives). Primary data included 8 online and face to face focus groups, conducted at approximately 10 week intervals, and 28 individual one to one interviews with members of the online community within six weeks of giving birth. A thematic analysis using a priori themes was undertaken. This involved coding data which evidenced relational, informational and management continuity across the entire dataset (28 interviews and 8 focus groups). The analysis was undertaken broadly following the six stages described by Braun and Clarke (2006). Relational and informational continuity were identified across the data. Relational continuity was evident for both the participants and the midwife moderators; informational continuity was described by the participants. Management continuity was not identified. Continuity through social media use was valued by both the mothers and the midwives. Information and relational continuity needs of women can be met using professionally moderated, social media based groups. They may

  9. Chimera States in Continuous Media: Existence and Distinctness

    Science.gov (United States)

    2017-12-01

    The defining property of chimera states is the coexistence of coherent and incoherent domains in systems that are structurally and spatially homogeneous. The recent realization that such states might be common in oscillator networks raises the question of whether an analogous phenomenon can occur in continuous media. Here, we show that chimera states can exist in continuous systems even when the coupling is strictly local, as in many fluid and pattern forming media. Using the complex Ginzburg-Landau equation as a model system, we characterize chimera states consisting of a coherent domain of a frozen spiral structure and an incoherent domain of amplitude turbulence. We show that in this case, in contrast with discrete network systems, fluctuations in the local coupling field play a crucial role in limiting the coherent regions. We suggest these findings shed light on new possible forms of coexisting order and disorder in fluid systems.

    2014-07-01

    Full Text Available CARMA is a media annotation program that collects continuous ratings while displaying audio and video files. It is designed to be highly user-friendly and easily customizable. Based on Gottman and Levenson’s affect rating dial, CARMA enables researchers and study participants to provide moment-by-moment ratings of multimedia files using a computer mouse or keyboard. The rating scale can be configured on a number of parameters including the labels for its upper and lower bounds, its numerical range, and its visual representation. Annotations can be displayed alongside the multimedia file and saved for easy import into statistical analysis software. CARMA provides a tool for researchers in affective computing, human-computer interaction, and the social sciences who need to capture the unfolding of subjective experience and observable behavior over time.

    Highlights: • We integrated a fluctuation beam emission measurement into the ITER CXRS prototype spectrometer. • The fluctuation BES measurement provided data at TEXTOR that agree well with the simulation based on the Simulation Of Spectra package. • The same simulation method has been used to evaluate the feasibility of a fluctuation BES measurement on the ITER DNB using the CXRS periscopes. -- Abstract: The ITER core CXRS diagnostic system collects the light emitted from the interaction of the diagnostic neutral beam with the core plasma and guides it via a mirror labyrinth through the upper port plug no. 3 towards a fiber bundle, which then transmits the light into a set of spectrometers for spectral analysis. In order to test the accessibility of the special parameter range required for the ITER measurement, a prototype spectrometer was built and operated successfully at the TEXTOR tokamak. In addition to the He/Be, C/Ne and H/D/T regular spectral channels, a fluctuation beam emission spectroscopy (BES) system has been integrated to measure core MHD activity, and validate corresponding ITER simulation results. The fluctuation system can be operated as an alternative to the spectral BES measurement, and has 8 spatial channels sampled at 2 MHz. In this paper, we present details of the fluctuation BES system and its interface to the ITER prototype spectrometer along with simulation and measurement results at TEXTOR. We show that the measurement fully confirms the simulation results on achievable photon current at the detector and on the signal to noise ratio.

  16. The Continued Relevance of Reception Analysis in the Age of Social Media

    DEFF Research Database (Denmark)

    2015-01-01

    Far from being a remnant of the past, reception analysis must continue to set the question of meaning as a central issue in media studies, an issue that appears to be missing from current understandings of social media in which audiences are often reduced to a single reality or simply ignored...... as empirical reality. This paper argues for the continued relevance of reception analysis, inspite of the mismatch of the label, and develops this argument by applying one of its most fundamental insights, namely its investigation of the relationship between media and audience —or between text and context......: 1) gatekeeping, 2) remix and 3) positioning. Resulting from this framework, three agendas are suggested for the study of audiences of social media: 1) the relationship between old and new media, 2) the “audiencification” of the text, and 3) the war between audiences....

  17. Future Perspectives on Baryon Form Factor Measurements with BES III

    Schönning, Karin; Li, Cui

    2017-03-01

    The electromagnetic structure of hadrons, parameterised in terms of electromagnetic form factors, EMFF's, provide a key to the strong interaction. Nucleon EMFF's have been studied rigorously for more than 60 years but the new techniques and larger data samples available at modern facilities have given rise to a renewed interest for the field. Recently, the access to hyperon structure by hyperon time-like EMFF provides an additional dimension. The BEijing Spectrometer (BES III) at the Beijing Electron Positron Collider (BEPC-II) in China is the only running experiment where time-like baryon EMFF's can be studied in the e+e- → BB̅ reaction. The BES III detector is an excellent tool for baryon form factor measurements thanks to its near 4π coverage, precise tracking, PID and calorimetry. All hyperons in the SU(3) spin 1/2 octet and spin 3/2 decuplet are energetically accessible within the BEPC-II energy range. Recent data on proton and Λ hyperon form factors will be presented. Furthermore, a world-leading data sample was collected in 2014-2015 for precision measurements of baryon form factors. In particular, the data will enable a measurement of the relative phase between the electric and the magnetic form factors for Λ and Λc+ and hyperons. The modulus of the phase can be extracted from the hyperon polarisation, which in turn is experimentally accessible via the weak, parity violating decay. Furthermore, from the spin correlation between the outgoing hyperon and antihyperon, the sign of the phase can be extracted. This means that the time-like form factors can be completely determined for the first time. The methods will be outlined and the prospects of the BES III form factor measurements will be given. We will also present a planned upgrade of the BES III detector which is expected to improve future form factor measurements.

    Cloud computing provides a new technical means for data processing of high energy physics experiment. However, the resource of each queue is fixed and the usage of the resource is static in traditional job management system. In order to make it simple and transparent for physicist to use, we developed a virtual cluster system (vpmanager) to integrate IHEPCloud and different batch systems such as Torque and HTCondor. Vpmanager provides dynamic virtual machines scheduling according to the job queue. The BES III use case results show that resource efficiency is greatly improved.

    This work focuses on the effects of an external mass media on continuous opinion dynamics with heterogeneous bounds of confidence. We modified the original Deffuant et al. and Hegselmann and Krause models to incorporate both, an external mass media and a heterogeneous distribution of confidence levels. We analysed two cases, one where only two bounds of confidence are taken into account, and other where each individual of the system has her/his own characteristic level of confidence. We found that, in the absence of mass media, diversity of bounds of confidence can improve the capacity of the systems to reach consensus. We show that the persuasion capacity of the external message is optimal for intermediate levels of heterogeneity. Our simulations also show the existence, for certain parameter values, of a counter-intuitive effect in which the persuasion capacity of the mass media decreases if the mass media intensity is too large. We discuss similarities and differences between the two heterogeneous versions of these continuous opinion dynamic models under the influence of mass media.

    2007-09-01

    GLoBES (General Long Baseline Experiment Simulator) is a flexible software package to simulate neutrino oscillation long baseline and reactor experiments. On the one hand, it contains a comprehensive abstract experiment definition language (AEDL), which allows to describe most classes of long baseline experiments at an abstract level. On the other hand, it provides a C-library to process the experiment information in order to obtain oscillation probabilities, rate vectors, and Δχ-values. Currently, GLoBES is available for GNU/Linux. Since the source code is included, the port to other operating systems is in principle possible. GLoBES is an open source code that has previously been described in Computer Physics Communications 167 (2005) 195 and in Ref. [7]). The source code and a comprehensive User Manual for GLoBES v3.0.8 is now available from the CPC Program Library as described in the Program Summary below.

    Reductive removal of nitrate in bioelectrochemical system (BES) at abiotic cathode, biocathode and biohydrogen facilitated biocathode were investigated. It was found that nitrate removal efficiency reached 95% and 59% at the biohydrogen facilitated biocathode and biocathode respectively, while which was only 13% at the abiotic cathode. Meanwhile, activity of nitrate reductase reached 0.701 g-N/Lh for the biohydrogen facilitated group, which was about 9.3 times of the biocathode group. Moreover, electrochemical performances as power density, ohmic resistance, and polarization resistance of the biohydrogen facilitated group reached 76.96 mW/m(3), 8.63 ohm and 383 ohm, respectively, which were better than two other groups. Finally, an obvious shift of bacterial community responsible for the enhanced nitrate reduction between the two biocathode groups was observed. Therefore, nitrate reduction in BES could be enhanced at the biocathode than that of the abiotic cathode, and then be further boosted with the combination of biohydrogen.

    Steady-state continuous culture was used to optimize lean chemically defined media for a Cellulomonas sp. and Bacillus cereus strain T. Both organisms were extremely sensitive to variations in trace-metal concentrations. However, medium optimization by this technique proved rapid, and multifactor screening was easily conducted by using a minimum of instrumentation. The optimized media supported critical dilution rates of 0.571 and 0.467 h−1 for Cellulomonas and Bacillus, respectively. These values approximated maximum growth rate values observed in batch culture. PMID:16345417

    Importance New dissemination methods are needed to engage physicians in evidence-based continuing medical education (CME). Objective To examine the effectiveness of social media in engaging physicians in non-industry-sponsored CME. Design We tested the effect of different media platforms (e-mail, Facebook, paid Facebook and Twitter), CME topics, and different “hooks” (e.g., Q&A, clinical pearl and best evidence) on driving clicks to a landing site featuring non-industry sponsored CME. We modelled the effects of social media platform, CME topic, and hook using negative binomial regression on clicks to a single landing site. We used clicks to landing site adjusted for exposure and message number to calculate rate ratios. To understand how physicians interact with CME content on social media, we also conducted interviews with 10 physicians. Setting The National Physicians Alliance (NPA) membership. Participants NPA e-mail recipients, Facebook followers and friends, and Twitter followers. Main Outcomes and Measures Clicks to the NPA’s CME landing site. Results On average, 4,544 recipients received each message. Messages generated a total of 592 clicks to the landing site, for a rate of 5.4 clicks per 1000 recipients exposed. There were 5.4 clicks from e-mail, 11.9 clicks from Facebook, 5.5 clicks from paid Facebook, and 6.9 clicks from Twitter to the landing site for 1000 physicians exposed to each of 4 selected CME modules. A Facebook post generated 2.3x as many clicks to the landing site as did an e-mail after controlling for participant exposure, hook type and CME topic (psocial media might not be a preferred vehicle for disseminating CME. Conclusions Social media has a modest impact on driving traffic to evidence-based CME options. Facebook had a superior effect on driving physician web traffic to evidence-based CME compared to other social media platforms and email. PMID:28060854

    Professional development is essential in the health disciplines. Knowing the cost and value of educational approaches informs decisions and choices about learning and teaching practices. The primary aim of this study was to conduct a cost analysis of participation in continuing professional development via social media compared with live conference attendance. Clinicians interested in musculoskeletal care were invited to participate in the study activities. Quantitative data were obtained from an anonymous electronic questionnaire. Of the 272 individuals invited to contribute data to this study, 150 clinicians predominantly from Australia, United States, United Kingdom, India, and Malaysia completed the outcome measures. Half of the respondents (78/150, 52.0%) believed that they would learn more with the live conference format. The median perceived participation costs for the live conference format was Aus $1596 (interquartile range, IQR 172.50-2852.00). The perceived cost of participation for equivalent content delivered via social media was Aus $15 (IQR 0.00-58.50). The majority of the clinicians (114/146, 78.1%, missing data n=4) indicated that they would pay for a subscription-based service, delivered by social media, to the median value of Aus $59.50. Social media platforms are evolving into an acceptable and financially sustainable medium for the continued professional development of health professionals. When factoring in the reduced costs of participation and the reduced loss of employable hours from the perspective of the health service, professional development via social media has unique strengths that challenge the traditional live conference delivery format.

    potentially revolutionary science involves soft excitations such as magnons and phonons; in general, these are well below the resolution that can be probed by today’s optical systems. The study of these low-energy excitations will only move forward if advances are made in high-resolution gratings for the soft X-ray energy region, and higher-resolution crystal analyzers for the hard X-ray region. In almost all the forefront areas of X-ray science today, the main limitation is our ability to focus, monochromate, and manipulate X-rays at the level required for these advanced measurements. To address these issues, the U.S. Department of Energy (DOE) Office of Basic Energy Sciences (BES) sponsored a workshop, X-ray Optics for BES Light Source Facilities, which was held March 27–29, 2013, near Washington, D.C. The workshop addressed a wide range of technical and organizational issues. Eleven working groups were formed in advance of the meeting and sought over several months to define the most pressing problems and emerging opportunities and to propose the best routes forward for a focused R&D program to solve these problems. The workshop participants identified eight principal research directions (PRDs), as follows: Development of advanced grating lithography and manufacturing for high-energy resolution techniques such as soft X-ray inelastic scattering. Development of higher-precision mirrors for brightness preservation through the use of advanced metrology in manufacturing, improvements in manufacturing techniques, and in mechanical mounting and cooling. Development of higher-accuracy optical metrology that can be used in manufacturing, verification, and testing of optomechanical systems, as well as at wavelength metrology that can be used for quantification of individual optics and alignment and testing of beamlines. Development of an integrated optical modeling and design framework that is designed and maintained specifically for X-ray optics. Development of

    Full Text Available The present study deals with a decolorization development of malachite green (MG dyeing wastewater using TiO2 thin films coated glass tube media in photoreactor. The TiO2 photocatalyst was synthesized by three methods: TTIP sol-gel, TiO2 powder-modified sol, and TiO2 powder suspension coating on raschig ring glass tube media and was investigated crystallinity phase by SEM, XRD, and AFM. Degradation kinetics of the dyeing wastewater by photocatalytic was carried out under UV light irradiation. The Langmuir first-order model provided the best fit to the experimental data. The catalyst prepared by powder suspension technique and coated on glass tube had given the highest of decolorization kinetics and efficiency. Continuous photoreactor packed with the TiO2 coating media was designed and proven to be the high effectiveness for MG dyeing degradation and stable throughout the recyclability test. The light intensity, dye solution flow rate, and TiO2 loading were the most important parameters that response to decolorization efficiency. The optimum condition of photo decolorization of MG dye solution can be obtained from RSM model. Effectiveness of the synthesized TiO2 thin films using suspension technique and the continuous photoreactor design were obtained with a great potential to be proven for wastewater treatment at industrial scale.

    Full Text Available Background The impact of social media and online learning in health professions education has previously shown generally positive results in medical, nursing and pharmacy students. To date there has not been any extensive research into social media and online learning use by prehospital health care professionals such as paramedics. Aim & Methods We sought to identify the extent to which Irish pre-hospital practitioners make use of online learning and social media for continuous professional competency (CPC, and the means by which they do so. A cross-sectional online survey of practitioners was conducted to obtain both quantitative and qualitative data. The release of the survey was in a controlled manner to PHECC registrants via various channels. Participation was voluntary and anonymous. Results A total of 248 respondents completed the survey in full by closing date of 31 March 2015, representing 5.4% of all registrants (n=4,555. 77% of respondents were male, and the majority were registered as Emergency Medical Technicians (49%, followed by Advanced Paramedics (26%. Over 78% of respondents used a mobile device in the course of their clinical duties; the majority used an iOS device. Social media and online learning were considered learning tools by over 75% of respondents, and over 74% agreed they should be further incorporated into prehospital education. The most popular platforms for CPC activities were YouTube and Facebook. The majority of respondents (88% viewed self-directed activities to constitute continuous professional development activity, but 64% felt that an activity that resulted in the awarding of a certificate was better value. Over 90% of respondents had previous experience with online learning, but only 42% indicated they had previously purchased or paid for online learning. Conclusion Prehospital practitioners in Ireland in the population studied consider online learning and social media acceptable for CPC purposes. The main

    We propose a unified physical framework for transport in variably saturated porous media. This approach allows fluid flow and solute migration to be treated as ensemble averages of fluid and solute particles, respectively. We consider the cases of homogeneous and heterogeneous porous materials. Within a fractal mobile-immobile continuous time random-walk framework, the heterogeneity will be characterized by algebraically decaying particle retention times. We derive the corresponding (nonlinear) continuum-limit partial differential equations and we compare their solutions to Monte Carlo simulation results. The proposed methodology is fairly general and can be used to track fluid and solutes particles trajectories for a variety of initial and boundary conditions.

    Achieving the understanding of the process of solute transport in heterogeneous porous media is of crucial importance for several environmental and social purposes, ranging from aquifers contamination and remediation, to risk assessment in nuclear waste repositories. The complexity of this aim is mainly ascribable to the heterogeneity of natural media, which can be observed at all the scales of interest, from pore scale to catchment scale. In fact, the intrinsic heterogeneity of porous media is responsible for the arising of the well-known non-Fickian footprints of transport, including heavy-tailed breakthrough curves, non-Gaussian spatial density profiles and the non-linear growth of the mean squared displacement. Several studies investigated the processes through which heterogeneity impacts the transport properties, which include local modifications to the advective-dispersive motion of solutes, mass exchanges between some mobile and immobile phases (e.g. sorption/desorption reactions or diffusion into solid matrix) and spatial correlation of the flow field. In the last decades, the continuous time random walk (CTRW) model has often been used to describe solute transport in heterogenous conditions and to quantify the impact of point heterogeneity, spatial correlation and mass transfer on the average transport properties [1]. Open issues regarding this approach are the possibility to relate measurable properties of the medium to the parameters of the model, as well as its capability to provide predictive information. In a recent work [2] the authors have shed new light on understanding the relationship between Lagrangian and Eulerian dynamics as well as on their evolution from arbitrary initial conditions. On the basis of these results, we derive a CTRW model for the description of Darcy-scale transport in d-dimensional media characterized by spatially random permeability fields. The CTRW approach models particle velocities as a spatial Markov process, which is

    2015-01-01

    Full Text Available This article explores the symbolic image of the “window” in Fyodor Sologub’s novel The Petty Demon (Melky bes, with a particular focus on the connections between literature, semiotics, and psychopathology. Windows can be thought of as thin and transparent frameworks which divide the external world (“the others” from the internal one (“the self”, but, at the same time, they allow interactions between the two as well. Peaceful interactions are seldom contemplated; in most cases, the individual ego clashes with the collectivity. This is what happens in Sologub’s Petty Demon. Here, windows represent the struggle of the novel’s anti-hero Peredonov against the world; they stand as a symbol of his alienation from Russian society and life. Windows appear several times in the novel to signify Peredonov’s troublesome relationship with other people. In particular, broken windows and glasses suggest a growing gap between “the self” and “the others”, Peredonov and reality. Imagery drawn from the visual field helps the author to describe the protagonist’s fall into madness. On one hand, Peredonov sees the world through his paranoid eyes, and considers “the others” as a threat to his own identity. Even though, on the other hand, it is Peredonov himself, who suffering from persecution mania, fears that he is spied on by enemies. At the end, alterity will triumph over him. Thus, the novel also portrays Peredonov’s tragedy: the loss of his own “self”.

    In this study, bioelectrochemical-upflow anaerobic sludge blanket (BES-UASB) system was developed for treatment of 2,4-dichloronitrobenzen (DClNB) containing wastewater to investigate the effect of external voltage with different supplying modes. Results showed that 2,4-dichloroaniline (DClAN) was under detection limit in R1 (applied with intermittent voltage) and R2 (applied with continuous voltage) when the DClNB loading increased from 25 to 100gm(3)d(-1) (hydraulic retention time (HRT) was decreased from 24 to 6h) while sudden accumulation of DClAN (1.7mgL(-1)) was observed in R0 (control). Dechlorination efficiency (DE) decreased to 32.7%, 45.0% and 45.3% in R0, R1 and R2 when HRT was further shortened to 4h. Microbial community analysis indicated the significant enrichment of dechlorination-related species in R1 and R2 compared with R0, e.g., Dehalobacter and Dehalococcoides. In summary, the BES-UASB system with intermittent voltage is an alternative process for efficient treatment of DClNB containing wastewater, and the energy input was reduced markedly.

    There is a large body of research on utilizing online activity as a survey of political opinion to predict real world election outcomes. There is considerably less work, however, on using this data to understand topic-specific interest and opinion amongst the general population and specific demographic subgroups, as currently measured by relatively expensive surveys. Here we investigate this possibility by studying a full census of all Twitter activity during the 2012 election cycle along with the comprehensive search history of a large panel of Internet users during the same period, highlighting the challenges in interpreting online and social media activity as the results of a survey. As noted in existing work, the online population is a non-representative sample of the offline world (e.g., the U.S. voting population). We extend this work to show how demographic skew and user participation is non-stationary and difficult to predict over time. In addition, the nature of user contributions varies substantially around important events. Furthermore, we note subtle problems in mapping what people are sharing or consuming online to specific sentiment or opinion measures around a particular topic. We provide a framework, built around considering this data as an imperfect continuous panel survey, for addressing these issues so that meaningful insight about public interest and opinion can be reliably extracted from online and social media data.

  20. Upscaling solute transport in naturally fractured porous media with the continuous time random walk method

    Solute transport in fractured porous media is typically 'non-Fickian'; that is, it is characterized by early breakthrough and long tailing and by nonlinear growth of the Green function-centered second moment. This behavior is due to the effects of (1) multirate diffusion occurring between the highly permeable fracture network and the low-permeability rock matrix, (2) a wide range of advection rates in the fractures and, possibly, the matrix as well, and (3) a range of path lengths. As a consequence, prediction of solute transport processes at the macroscale represents a formidable challenge. Classical dual-porosity (or mobile-immobile) approaches in conjunction with an advection-dispersion equation and macroscopic dispersivity commonly fail to predict breakthrough of fractured porous media accurately. It was recently demonstrated that the continuous time random walk (CTRW) method can be used as a generalized upscaling approach. Here we extend this work and use results from high-resolution finite element-finite volume-based simulations of solute transport in an outcrop analogue of a naturally fractured reservoir to calibrate the CTRW method by extracting a distribution of retention times. This procedure allows us to predict breakthrough at other model locations accurately and to gain significant insight into the nature of the fracture-matrix interaction in naturally fractured porous reservoirs with geologically realistic fracture geometries.

  1. A Continuous Family of Equilibria in Ferromagnetic Media are Ground States

    We show that a foliation of equilibria (a continuous family of equilibria whose graph covers all the configuration space) in ferromagnetic transitive models are ground states. The result we prove is very general, and it applies to models with long range and many-body interactions. As an application, we consider several models of networks of interacting particles including models of Frenkel-Kontorova type on Z^d and one-dimensional quasi-periodic media. The result above is an analogue of several results in the calculus of variations (fields of extremals) and in PDE's. Since the models we consider are discrete and long range, new proofs need to be given. We also note that the main hypothesis of our result (the existence of foliations of equilibria) is the conclusion (using KAM theory) of several recent papers. Hence, we obtain that the KAM solutions recently established are minimizers when the interaction is ferromagnetic and transitive (these concepts are defined later).

    The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present Focus Issue. Synchronization between a system and its model, based on limited observations, gives a new perspective on data assimilation. Synchronization among different models of the same system defines a supermodel that can achieve partial consensus among models that otherwise disagree in several respects. Finally, novel methods of time series analysis permit a better description of synchronization in a system that is only observed partially and for a relatively short time. This Focus Issue discusses synchronization in extended systems or in components thereof, with particular attention to data assimilation, supermodeling, and their applications to various areas, from climate modeling to macroeconomics.

    To determine continuing medical education (CME) course participants' use of social media (SM) and their attitudes about the value of SM for enhancing CME education and to examine associations between participants' characteristics and attitudes toward SM. We conducted a cross-sectional survey and validation study of 539 participants at a Mayo Clinic Internal Medicine CME course in November 2011. The Social Media Use and Perception Instrument (SMUPI) consisted of 10 items (5-point Likert scales) and categorical response options. The main outcome measures were psychometric characteristics of the SMUPI scale, course participants' use of SM, and their attitudes regarding the importance of SM for enhancing CME. Of 539 CME course participants, 327 (61%) responded to the SMUPI survey. Most respondents (291 [89%]) reported using SM, with the most common types being YouTube (189 of the 327 participants [58%]) and Facebook (163 of 327 [50%]). Factor analysis revealed a 2-dimensional assessment of course participants' attitudes. Internal consistency reliability (Cronbach α) was excellent for factor 1 (0.94), factor 2 (0.89), and overall (0.94). The CME course participants' favorable attitudes toward SM were associated with younger age (20-29 years, mean score 3.13; 30-39 years, 3.40; 40-49 years, 3.39; 50-59 years, 3.18; 60-69 years, 2.93; and ≥70 years, 2.92; P=.02), using SM frequently (never, mean score 2.49; less than once monthly, 2.75; once monthly, 3.21; weekly, 3.31; and daily, 3.81; PEducation and Research.

    A new Beam Emission Spectroscopy (BES) diagnostic has been deployed at the NSTX. It exploits new detectors and optical systems adapted to the large pitch angles on the spherical torus. The detectors consist of surface-mount, wide-area photoconductive photodiodes and a new frequency-compensated broadband preamplifier to achieve photon-noise limited measurements. Advantages of the new system include an increased effective bandwidth of 1 MHz and elimination of the need for cryogenic cooling. First measurements have been obtained using 16 channels, with plans to expand to 32 in the near future. These measurements show coherent and broadband plasma turbulence in high gradient regions, and coherent modes that mainly correlate with Alfvén/energetic particle modes. To support these BES experiments at NSTX and similar ones at DIII-D, Langmuir probe measurements in Pegasus ST plasmas are being evaluated for validation of velocimetry techniques using 2D BES ñmeasurements.

    Shoulder pain and dysfunction are common after oncologic neck dissection for head and neck cancer (HNC), due to traction, compression, and devascularization injuries to the spinal accessory nerve (SAN). Shoulder pain and dysfunction can hinder postoperative rehabilitation and hygiene, activities of daily living (ADLs), and return to work after treatment for HNC. Due to the rising incidence of human papillomavirus (HPV)-associated oropharyngeal cancer, patients are often diagnosed in the third or fourth decade of life, leaving many potential working years lost if shoulder dysfunction occurs. Brief electrical stimulation (BES) is a novel technique that has been shown to enhance and accelerate neuronal regeneration after injury through a brain-derived neurotrophic growth factor (BDNF)-driven molecular pathway in multiple peripheral nerves in both humans and animals. This is a randomized controlled trial testing the effect of intraoperative BES on postoperative shoulder pain and dysfunction. All adult participants with a new diagnosis of HNC undergoing surgery with neck dissection, including Level IIb and postoperative radiotherapy, will be enrolled. Participants will undergo intraoperative BES after completion of neck dissection for 60 min continuously at 20 Hz, 3 to 5 V, in 100-msec pulses. Postoperatively, participants will be evaluated using the Constant-Murley Shoulder Score, a scale that assesses shoulder pain, ADLs, strength, and range of motion. Secondary outcomes measured will include nerve conduction studies (NCS) and electromyographic (EMG) studies, as well as scores on the Oxford Shoulder Score (OSS), the Neck Dissection Impairment Index (NDII), and the University of Washington Quality of Life (UW-QOL) score. Primary and secondary outcomes will be assessed at 6 weeks, 3 months, 6 months, and 12 months. The objective of this study is to evaluate the effect of BES on postoperative clinical and objective shoulder functional outcomes and pain after oncologic

    Full Text Available INTRODUCTION: The procedure for determining an adequate literacy and learning method among students with visual impairments consists two components: an initial choice of mode of literacy, to be conducted during the early childhood and continuing evaluation of the literacy and learning method, which is carried out over students who have already been involved in the educational process for a certain period and with whom a mediums for literacy and learning has already been determined.PURPOSE: The purpose of this research is to conduct a re-evaluation of the initial decision regarding the choice of media through which education is conducted among students with visual impairment.DISCUSSION: The speed of reading is substantially below the predicted minimum level both with students who read Braille and with students who read regular print. It should be mentioned that only 3 respondents out of 15 Braille readers were cooperative in this part of the research, so they obtained results regarding them should not be taken as reliable ones. 100% of the respondents who are educated using the Braille alphabet independently read unfamiliar formal and also familiar educational material. Among the students who use regular print, 62.5% read independently and the other 37.5% need additional instruction. 45.5% of them successfully completed their school assignments using their initially chosen medium for literacy and learning, but only 18.2% of them do it in an acceptable time period. 53.6% of respondents know how to use available resources and facilities that exist within the school, while the other 46, 4% need additional training and instructions.CONCLUSION: Continuous evaluation should be implemented consistently throughout the schooling of the child, or at least once a year, for a relevant "justification" for any change, addition or selection of another sensory channel for learning and literacy of the child, as a result of certain changes in visual functioning of

  13. Continuous-time random-walk model for anomalous diffusion in expanding media

    Le Vot, F.; Abad, E.; Yuste, S. B.

    2017-09-01

    Expanding media are typical in many different fields, e.g., in biology and cosmology. In general, a medium expansion (contraction) brings about dramatic changes in the behavior of diffusive transport properties such as the set of positional moments and the Green's function. Here, we focus on the characterization of such effects when the diffusion process is described by the continuous-time random-walk (CTRW) model. As is well known, when the medium is static this model yields anomalous diffusion for a proper choice of the probability density function (pdf) for the jump length and the waiting time, but the behavior may change drastically if a medium expansion is superimposed on the intrinsic random motion of the diffusing particle. For the case where the jump length and the waiting time pdfs are long-tailed, we derive a general bifractional diffusion equation which reduces to a normal diffusion equation in the appropriate limit. We then study some particular cases of interest, including Lévy flights and subdiffusive CTRWs. In the former case, we find an analytical exact solution for the Green's function (propagator). When the expansion is sufficiently fast, the contribution of the diffusive transport becomes irrelevant at long times and the propagator tends to a stationary profile in the comoving reference frame. In contrast, for a contracting medium a competition between the spreading effect of diffusion and the concentrating effect of contraction arises. In the specific case of a subdiffusive CTRW in an exponentially contracting medium, the latter effect prevails for sufficiently long times, and all the particles are eventually localized at a single point in physical space. This "big crunch" effect, totally absent in the case of normal diffusion, stems from inefficient particle spreading due to subdiffusion. We also derive a hierarchy of differential equations for the moments of the transport process described by the subdiffusive CTRW model in an expanding medium

    The aim of this study is to determine whether blastocyst utilization rates are different after continuous culture in two different commercial single-step media. This is a paired randomized controlled trial with sibling oocytes conducted in infertility patients, aged ≤40 years with ≥10 oocytes retrieved assigned to blastocyst culture and transfer. Retrieved oocytes were randomly allocated to continuous culture in either Sage one-step medium (Origio) or Continuous Single Culture (CSC) medium (Irvine Scientific) without medium renewal up to day 5 post oocyte retrieval. Main outcome measure was the proportion of embryos suitable for clinical use (utilization rate). A total of 502 oocytes from 33 women were randomly allocated to continuous culture in either Sage one-step medium (n = 250) or CSC medium (n = 252). Fertilization was performed by either in vitro fertilization or intracytoplasmic sperm injection, and embryo transfers were performed on day 5. Two patients had all blastocysts frozen due to the occurrence of severe ovarian hyperstimulation syndrome. Fertilization and cleavage rates, as well as embryo quality on day 3, were similar in the two media. Blastocyst utilization rates (%, 95% CI) [55.4% (46.4-64.1) vs 54.7% (44.9-64.6), p = 0.717], blastocyst formation rates [53.6% (44.6-62.5) vs 51.9 (42.2-61.6), p = 0.755], and proportion of good quality blastocysts [36.8% (28.1-45.4) vs 36.1% (27.2-45.0), p = 0.850] were similar in Sage one-step and CSC media, respectively. Continuous culture of embryos in Sage one-step and CSC media is associated with similar blastocyst development and utilization rates. Both single-step media appear to provide adequate support during in vitro preimplantation embryo development. Whether these observations are also valid for other continuous single medium protocols remains to be determined. NCT02302638.

    Full Text Available Asia has some of the largest, most dynamic, diversified, and complicated media industries in the world (McKinsey & Company, 2015. Entering the 21st Century, the rapid economic and political developments of Asia further energize the growth of media locally and globally (for general discussion, see, e.g., Keane [2006]; Thussu [2006], specific discussions on the cases of Korea [Kim, 2013], Japan [Iwabuchi, 2004], China [Sun, 2009]. In a reflection on the increasing importance of Asian players in global communication industry, Keane describes that “Asianness is colonizing international communications markets” (2006: 839-840 with the impacts ranging from the production of hardware (i.e., East Asian technology to content (e.g., Japanese manga, anime and TV formats and South Korean popular culture and from the cross-over of directors and actors from Asia to Hollywood and the world. Yet, a lack of timely understanding of media and communication in a fast-changing Asia is hindering not only our interpretation of the significance of media in social transformation in Asia, but also the efforts to de-westernize (e.g., Park & Curran, 2000; Wang, 2010 or internationalize communication studies (Lee, 2014.

    Highlights: • Li-BES detection system on the COMPASS tokamak is optimized observation system with high temporal resolution. • High sensitivity to low level light fluctuations. • Optics and detectors with electronics are placed in thermally stabilized compact box. • Fast deflection system allows us to measure background corrected electron density profiles on microsecond time-scale. - Abstract: A new Li beam emission spectroscopy (Li-BES) diagnostic system with a ∼ cm spatial resolution, and with beam energy ranging from 10 keV up to 120 keV and a 18 channel Avalanche photo diode (APD) detector system sampled at 2 MHz has been recently installed and tested on the COMPASS tokamak. This diagnostic allows to reconstruct density profile based on directly measured light profiles, and to follow turbulent behaviour of the edge plasma. The paper reports technical capabilities of this new system designed for fine spatio-temporal measurements of plasma electron density. Focusing on turbulence-induced fluctuation measurements, we demonstrate how physically relevant information can be extracted using the COMPASS Li-BES system.

    The work presented here investigates the phenomenon of shock wave propagation in gas continuous, two-phase media. The motivation for this work stems from the need to understand blast venting consequences in the HYLIFE inertial confinement fusion (ICF) reactor. The HYLIFE concept utilizes lasers or heavy ion beams to rapidly heat and compress D-T targets injected into the center of a reactor chamber. A segmented blanket of failing molten lithium or Li2BeF4 (Flibe) jets encircles the reactors central cavity, shielding the reactor structure from radiation damage, absorbing the fusion energy, and breeding more tritium fuel.

    A new near-infrared coherent imaging technique that can reveal scattering bodies embedded in highly scattering media is presented. Its underlying principle is extended from frequency modulated continuous wave radar systems. This technique has advantages over low coherence tomography as it does not require the reference mirror to be scanned. The tunable laser is characterized and the system's performance is demonstrated on images recorded from solid scattering phantoms. Furthermore a combination of our chirp-tomography (C-OCT) and laser Doppler perfusion imaging (LDPI) is demonstrated. The influence of moving scatterers on the tomographic images are discussed.

    Experimental observations of spatial focusing of continuous-wave, steady-state elastic waves in a reverberant elastic cavity using time reversal are reported here. Spatially localized focusing is achieved when multiple channels are employed, while a single channel does not yield such focusing. The amplitude of the energy at the focal location increases as the square of the number of channels used, while the amplitude elsewhere in the medium increases proportionally with the number of channels used. The observation is important in the context of imaging in solid laboratory samples as well as problems involving continuous-wave signals in Earth.

    Arsenic constitutes a serious environmental problem for the mineral processing industries. The removal of high concentrations of arsenic in the case of uranium milling process effluents is done by adjusting the iron to arsenic molar ratio to four (MFe{sub tot}/MAs=4) and subsequently neutralizing with slaked lime in a continuous coprecipitation (CCPTN) circuit. This paper investigates the production of arsenic-bearing phases though CCPTN from simulated waste process effluents and their long term stability at accelerated conditions. In particular, special attention is given to a two stage continuous reactor set-up. Moreover, the effect of a fraction of total iron as ferrous iron and the presence of co-ions such as nickel and aluminum on the stability of the products was investigated. (author)

  4. The basic components of residual migration in VTI media using anisotropy continuation

    KAUST Repository

    Alkhalifah, Tariq Ali

    2011-03-24

    We introduce anisotropy continuation as a process which relates changes in seismic images to perturbations in the anisotropic medium parameters. This process is constrained by two kinematic equations, one for perturbations in the normal-moveout (NMO) velocity and the other for perturbations in the dimensionless anisotropy parameter ?. We consider separately the case of post-stack migration and show that the kinematic equations in this case can be solved explicitly by converting them to ordinary differential equations using the method of characteristics. When comparing the results of kinematic analytical computations with synthetic numerical experiments confirms the theoretical accuracy of the method.

    Composite Fe2O3/ACF electrode facilitated methyl orange (MO) oxidative degradation using bio-electro-Fenton in bioelectrochemical system (BES) was investigated. Characterized by both XPS and FT-IR techniques, it was found that the composite Fe2O3/ACF electrode with highest Fe loading capacity of 11.02% could be prepared after the carbon felt was oxidized with nitric acid. Moreover, hydrogen peroxide production reached steadily at 88.63 μmol/L with the external resistance as 100 Ω, cathodic aeration rate at 750 mL/min, and the pH of the bio-electro-Fenton system adjusted to 2. Significantly, not only the electrochemical profiles of the BES reactor as electrochemical impedance spectroscopy (EIS) was bettered, but the MO oxidative degradation could be accomplished for eight repeated batches, with the MO removal efficiency varied slightly from 73.9% to 86.7%. It indicated that the bio-electro-Fenton might be a promising eco-friendly AOP method for Azo-dye wastewater treatment. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Ocular damage threshold data remain sparse in the continuous wave (CW), near-infrared (NIR) radiation region save for the 1300-nm area that has been investigated in the past several decades. The 1300-nm ocular damage data have yielded unusual characteristics where CW retinal damage was observed in rabbit models, but never in nonhuman primate models. This paper reviews the existing 1300-nm ocular damage threshold data in terms of the fundamental criteria of an action spectrum to assist in explaining laser-tissue effects from near-infrared radiation in the eye. Reviewing the action spectrum criteria and existing NIR retinal lesion data lend evidence toward the significant presence of thermal lensing in ocular media affecting damage, a relatively unexplored mechanism of laser-tissue interaction.

  7. Batch and continuous production of stable dense suspensions of drug nanoparticles in a wet stirred media mill

    Science.gov (United States)

    Afolabi, Afola we mi

    One way to improve the bioavailability of poorly water-soluble drugs is to reduce particle size of drug crystals down to nanoscale via wet stirred media milling. An increase in total surface area per mass loading of the drug and specific surface area as well as reduced external mass transfer resistance allow a faster dissolution of the poorly-water soluble drug from nanocrystals. To prevent aggregation of nanoparticles, polymers and surfactants are dissolved in water acting as stabilizers via adsorption onto the drug crystals. In the last two decades, ample experimental data were generated in the area of wet stirred media milling for the production of drug nanoparticle suspensions. However, a fundamental scientific/engineering understanding of various aspects of this process is still lacking. These challenges include elucidation of the governing mechanism(s) during nanoparticle formation and physical stabilization of the nanosuspension with the use of polymers and surfactants (formulation parameters), understanding the impact of process parameters in the context of first-principle-based models, and production of truly nanosized drug particles (10-100 nm) with acceptable physical stability and minimal contamination with the media. Recirculation mode of milling operation, where the drug suspension in a holding tank continuously circulates through the stirred media mill, has been commonly used in lab, pilot, and commercial scales. Although the recirculation is continuous, the recirculation operation mode is overall a batch operation, requiring significant number of batches for a large-volume pharmaceutical product. Hence, development and investigation of a truly continuous process should offer significant advantages. To explain the impact of some of the processing parameters, stress intensity and stress number concepts were widely used in literature, which do not account for the effect of suspension viscosity explicitly. The impact of the processing parameters has not

    Nanoparticles of BCS Class II drugs are produced in wet stirred media mills operating in batch or recirculation mode with the goal of resolving the poor water-solubility issue. Scant information is available regarding the continuous production of drug nanoparticles via wet media milling. Griseofulvin and Naproxen were milled in both recirculation mode and multi-pass continuous mode to study the breakage dynamics and to determine the effects of suspension flow rate. The evolution of the median particle size was measured and described by an empirical breakage model. We found that these two operation modes could produce drug nanosuspensions with similar particle size distributions (PSDs). A reduced suspension flow rate slowed the breakage rate and led to a wider PSD and more differentiation between the two operation modes. The latter part of this study focused on the roles of stabilizers (hydroxypropyl cellulose and sodium lauryl sulfate) and elucidation of the so-called Rehbinder effect (reduction in particle strength due to adsorbed stabilizers such as polymers and surfactants). Milling the drugs in the absence of the stabilizers produced primary nanoparticles and their aggregates, while milling with the stabilizers produced smaller primary nanoparticles with minimal aggregation. Using laser diffraction, BET nitrogen adsorption, scanning electron microscopy imaging, and a microhydrodynamic analysis of milling, this study, for the first time, provides sufficient evidence for the existence of the Rehbinder effect during the milling of drugs. Not only do the polymers and surfactants allow proper stabilization of the nanoparticles in the suspensions, but they also do facilitate drug particle breakage.

  9. A continuity-preserving and divergence-cleaning algorithm based on purely and damped hyperbolic Maxwell equations in inhomogeneous media

    In the numerical solution of Maxwell's equations for dynamic electromagnetic fields, the two Gauss's laws are usually not considered since they are a natural consequence of Faraday's and Maxwell-Ampère's laws if the charge conservation law is satisfied. However, when the charge conservation law is not satisfied, the numerical errors of Gauss's laws will increase unbounded, leading to numerical instability or breakdown. Unfortunately, the charge conservation law can be easily violated in self-consistent wave-particle simulations. In the meantime, the violation of Gauss's laws will also result in an increased error in the normal flux continuity. In the simulations of pure electromagnetic problems, the satisfaction of tangential field continuity across a material interface is sufficient to yield accurate numerical results. However, in a self-consistent wave-particle simulation, the normal components are as important as the tangential components, since they are critical in predicting the particle kinetics. In this paper, a divergence-cleaning method is presented to enforce Gauss's laws and normal flux continuity by introducing auxiliary variables and damping terms into Maxwell's equations in inhomogeneous media, which yield hyperbolic and mixed hyperbolic-parabolic Maxwell equations. The numerical solution schemes of the resulting purely and damped hyperbolic Maxwell equations are introduced under the framework of the discontinuous Galerkin time-domain method. It is shown through several numerical examples that the proposed method is able to preserve the continuity conditions for both tangential field components and normal flux components, and is effective in cleaning the numerical errors in both Gauss's laws.

    The use of chemometric techniques and multivariate experimental designs for the photocatalytic reaction of reactive scarlet BES in aqueous solution under ultraviolet light irradiation is described. The efficiency of photocatalytic degradation was evaluated by the analysis of the parameter of decoloration efficiency determined by UV absorption at 540 nm using a UV-Vis spectrophotometer in different conditions. Five factors, such as the amount of titanium oxide ([TiO2]), the concentrations of reactive scarlet BES (c(0)), irradiation time (t), the pH value (pH) and temperature (T), were studied. [TiO2]. c(0), t and pH selected on the basis of the results of variance analysis by Plackett-Burman design were used as independent variables. Training sets and test sets of back propagation neural network (BPNN) were formed by Box-Behnken design and uniform design U10 (10 x 5(2) x 2) respectively. The process of photocatalytic degradation of the target object was simulated by the BPNN model. The correlation coefficient (r) of the calculation results for training set and test set by BPNN is 0.996 4 and 0.963 6 respectively, and the mean relative errors between the predictive value and experimental value of decoloration efficiency are 6.14 and 7.76, respectively. The modeled BPNN was applied to analyze the influence of four factors on decoloration efficiency. The results showed that the initial conditions of c(0) being lower, pH 5.0 and appropriate amount of [TiO2] contribute to improving the decoloration efficiency of reactive scarlet BES. Under the condition of c(0) = 40 mg x L(-1), the optimized experimental condition of the system was obtained: [TiO2] = 1.20 g x L(-1) and pH 5.0. Under the optimized experimental condition, the experimental value of decoloration efficiency is 98.20% when irradiation time is 35 minutes and the predictive value of decoloration efficiency is 99.16% under the same condition. The relative error of decoloration efficiency between the predictive

    The work presented here investigates the phenomenon of shock wave propagation in gas continuous, two-phase media. The motivation for this work stems from the need to understand blast venting consequences in the HYLIFE inertial confinement fusion (ICF) reactor. The HYLIFE concept utilizes lasers or heavy ion beams to rapidly heat and compress D-T targets injected into the center of a reactor chamber. A segmented blanket of falling molten lithium or Li2BeF4 (Flibe) jets encircles the reactor`s central cavity, shielding the reactor structure from radiation damage, absorbing the fusion energy, and breeding more tritium fuel. X-rays from the fusion microexplosion will ablate a thin layer of blanket material from the surfaces which face toward the fusion site. This generates a highly energetic vapor, which mostly coalesces in the central cavity. The blast expansion from the central cavity generates a shock which propagates through the segmented blanket - a complex geometry, gas-continuous two-phase medium. The impulse that the blast gives to the liquid as it vents past, the gas shock on the chamber wall, and ultimately the liquid impact on the wall are all important quantities to the HYLIFE structural designers.

    Starting with the basic notions and facts of the mathematical theory of waves illustrated by numerous examples, exercises, and methods of solving typical problems Chapters 1 & 2 show e.g. how to recognize the hyperbolicity property, find characteristics, Riemann invariants and conservation laws for quasilinear systems of equations, construct and analyze solutions with weak or strong discontinuities, and how to investigate equations with dispersion and to construct travelling wave solutions for models reducible to nonlinear evolution equations. Chapter 3 deals with surface and internal waves in an incompressible fluid. The efficiency of mathematical methods is demonstrated on a hierarchy of approximate submodels generated from the Euler equations of homogeneous and non-homogeneous fluids. The self-contained presentations of the material is complemented by 200+ problems of different level of difficulty, numerous illustrations, and bibliographical recommendations.

    Ding, Weiwei; Du, Yihong; Liang, Xing

    2017-05-01

    We aim to classify the long-time behavior of the solution to a free boundary problem with monostable reaction term in space-time periodic media. Such a model may be used to describe the spreading of a new or invasive species, with the free boundary representing the expanding front. In time-periodic and space homogeneous environment, as well as in space-periodic and time autonomous environment, such a problem has been studied recently in [11,12]. In both cases, a spreading-vanishing dichotomy has been established, and when spreading happens, the asymptotic spreading speed is proved to exist by making use of the corresponding semi-wave solutions. The approaches in [11,12] seem difficult to apply to the current situation where the environment is periodic in both space and time. Here we take a different approach, based on the methods developed by Weinberger [31,32] and others [16,22-24,26], which yield the existence of the spreading speed without using traveling wave solutions. In Part 1 of this work, we establish the existence and uniqueness of classical solutions for the free boundary problem with continuous initial data, extending the existing theory which was established only for C2 initial data. This will enable us to develop Weinberger's method in Part 2 to determine the spreading speed without knowing a priori the existence of the corresponding semi-wave solutions. In Part 1 here, we also establish a spreading-vanishing dichotomy.

  17. Application of Bioelectrochemical Process (BES) for Electricity Generation and Sustainable Wastewater Treatment

    Science.gov (United States)

    Kim, Jung Rae

    Bioelectrochemical system such as microbial fuel cells (MFCs) and microbial electrolysis cell are an emerging technology which converts biodegradable organic matter to electrical energy or hydrogen using a biofilm on the electrode as the biocatalyst. It has recently been shown that waste-to-energy technology based on MFC can treat organic contaminant in domestic or industrial wastewater and simultaneously produce electricity. The maximum power density increased up to 1kW/m3 based on reactor volume. Bioelectrochemical systems may reduce the energy consumption for wastewater treatment by replacing energy intensive aeration of present treatment systems, while generate electrical energy from waste. In addition, the biomass production in MFCs has been reported to be 10-50% of conventional wastewater treatment, leading to reduce environmental impact and disposal costs. Various electrochemically active bacteria metabolize biodegradable organic compounds then discharge electrons to an extracellular electron acceptor for bacterial respiration. These bacteria also transfer electrons to electrodes by direct electron transfer, electron mediators or shuttles, and electrically conductive nanowires. Investigation of bacterial electron transport mechanisms may improve understanding of the biomaterial involved and metabolic pathways as well as improving power from MFCs. Biofuel cell systems require interdisciplinary research ranging from electrochemistry, microbiology, material science and surface chemistry to engineering such as reactor design, operation and modelling. Collaboration within each study and integration of systems might increase the performance and feasibility of BES process for sustainable energy.

    2015-02-02

    On February 2, 2015 the Offices of High Energy Physics (HEP) and Basic Energy Sciences (BES) convened a Round Table discussion among a group of physicists on ‘Common Problems in Condensed Matter and High Energy Physics’. This was motivated by the realization that both fields deal with quantum many body problems, share many of the same challenges, use quantum field theoretical approaches and have productively interacted in the past. The meeting brought together physicists with intersecting interests to explore recent developments and identify possible areas of collaboration.... Several topics were identified as offering great opportunity for discovery and advancement in both condensed matter physics and particle physics research. These included topological phases of matter, the use of entanglement as a tool to study nontrivial quantum systems in condensed matter and gravity, the gauge-gravity duality, non-Fermi liquids, the interplay of transport and anomalies, and strongly interacting disordered systems. Many of the condensed matter problems are realizable in laboratory experiments, where new methods beyond the usual quasi-particle approximation are needed to explain the observed exotic and anomalous results. Tools and techniques such as lattice gauge theories, numerical simulations of many-body systems, and tensor networks are seen as valuable to both communities and will likely benefit from collaborative development.

    We investigate the effect of varying the ion temperature gradient (ITG) and toroidal equilibrium scale sheared flow on ion-scale turbulence in the outer core of MAST by means of local gyrokinetic simulations. We show that nonlinear simulations reproduce the experimental ion heat flux and that the experimentally measured values of the ITG and the flow shear lie close to the turbulence threshold. We demonstrate that the system is subcritical in the presence of flow shear, i.e., the system is formally stable to small perturbations, but transitions to a turbulent state given a large enough initial perturbation. We propose that the transition to subcritical turbulence occurs via an intermediate state dominated by low number of coherent long-lived structures, close to threshold, which increase in number as the system is taken away from the threshold into the more strongly turbulent regime, until they fill the domain and a more conventional turbulence emerges. We show that the properties of turbulence are effectively functions of the distance to threshold, as quantified by the ion heat flux. We make quantitative comparisons of correlation lengths, times, and amplitudes between our simulations and experimental measurements using the MAST BES diagnostic. We find reasonable agreement of the correlation properties, most notably of the correlation time, for which significant discrepancies were found in previous numerical studies of MAST turbulence.

    Quiescent H-mode (QH) is an ELM-free scenario with good energy confinement, constant density, and radiated power, with a pedestal localized electromagnetic mode (edge harmonic oscillation, EHO) providing continuous particle transport. The features and characteristics of QH-mode plasma turbulence in the wavenumber-frequency domain are crucial to understanding the mechanisms and dynamics of the enhanced particle transport. Frequency-wavenumber spectral analysis was applied to localized density fluctuation data measured with BES on DIII-D in the region of 0.8 < ρ < 1.0 . In the analysis, a Maximum Entropy Method is applied in the space domain, instead of an FFT, to estimate a well resolved k-spectrum spectrum from truncated data. The fundamental frequency of the EHO was typically 10 kHz with long poloidal wavelength (kθ 0.02cm-1), while broadband turbulence was observed in the range of 50-200 kHz with correlation lengths of a few cm. The broadband turbulence measured at ρ 0.9 was found to have poloidal phase velocity of 10 km/s, which corresponds to the E ×B velocity. Work supported by US DOE Grant DE-FC02-04ER54698.

    Full Text Available Purpose: Clinical developments continue to grow at an accelerated rate, challenging the existing paradigm of information access, dissemination and learning by trainees. The aim of this study was to deliver relevant, concise and newly emerging information on cardiovascular disease using Twitter, and assess its impact. Methods: A Twitter account for our institution’s cardiovascular disease fellowship program was established. All fellows and faculty were encouraged to follow tweets for clinical developments. To assess Twitter use, participation rates and the number of tweets by topics and followers were tracked longitudinally. Impact on fellows was assessed through a brief evaluation survey and an emailed clinical vignette quiz that required the application of evidence to clinical questions. Results: Since project onset in September 2013, there have been 458 tweets, including 21 Health Insurance Portability and Accountability Act (HIPAA-compliant photos and videos, available to 48 followers, including 7 faculty and 20 current or former fellows. More than 60% of fellows achieved perfect quiz performance scores. Evaluations were completed by 94% of fellows (15/16, 25% of whom report checking for information at least every other day, 50% once a week and 25% once a month. Trainees report more frequent literature-based deliberations with faculty since Twitter inception. Conclusions: Twitter can deliver relevant, concise and newly emerging clinical information to trainees, impacting their ability to apply evidence to clinical problems. Trainee and faculty engagement with Twitter increases over time.

    In order to analyze the immunopathologic mechanisms of Behçet's disease, the gene (bes-1) encoding a streptococcal antigen correlated with the disease was cloned and sequenced, and protein produced by this clone was identified by Western immunoblotting using serum antibody from the patient. Cellular DNA of Streptococcus (S.) sanguis serotype KTH-1 (uncommon serotype 1, strain 113-20) from the patient was extracted and digested with EcoRI. The digested fragments were cloned into the cloning vector lambda gt11, and then the resulting DNA library was immunoscreened using the patient's serum antibody to serotype KTH-1. The immunopositive clone of the 1.5 kbp fragment was subcloned into pUC 118 plasmid (pU8BeS1-1) and sequenced. The sequence showed that the 3'-terminal half side region of this insert contained 962bp of open-reading frame (ORF) discontinued at the EcoRI restriction site, and the stop codon was not found. The nucleotide sequence of the remaining additional 3'-terminal region of this gene encoding whole BES-1 was determined by genome walking. The whole ORF of bes-1 consisted of 849 amino acid residues with a calculated molecular mass of 95 kDa. The residues in a portion of the amino acid sequence showed a 60% correspondence to those of the human intraocular peptide Brn-3b.

  9. Potential uses of pumped urban groundwater: a case study in Sant Adrià del Besòs (Spain)

    2017-09-01

    Urban groundwater has often been over-exploited for industrial uses. Now, this usage tends to be reduced or the resource abandoned due to pollution and/or changes in land use. The use and the subsequent disuse of groundwater has resulted in rising water tables that damage underground structures (e.g., building basements and underground car parks and tunnels), leading to the need for additional pumping in urban areas. In the case of the underground parking lot of Sant Adrià del Besòs (Barcelona, NE Spain), large amounts of urban groundwater are pumped to avoid seepage problems. Can this pumped groundwater be used for other purposes (e.g., drinking water and urban irrigation) instead of wasting this valuable resource? To answer this question, it was necessary to quantify the groundwater recharge and to assess the evolution of groundwater quality. The limiting factor at this study site is the groundwater quality because ammonium and some metals (iron and manganese) are present at high concentrations. Hence, further treatment would be needed to meet drinking water requirements. The pumped groundwater could also be used for supplementing river flow for ecological benefit and/or for mitigating seawater intrusion problems. Currently, only a small amount of this urban groundwater is used for cleaning public areas and watering public gardens. This situation highlighted the urgent need to manage this resource in a responsible and more efficient manner, especially in moments of high water demand such as drought periods.

  11. Final Report for the DOE-BES Program Mechanistic Studies of Activated Hydrogen Release from Amine-Boranes

    Energy Technology Data Exchange (ETDEWEB)

    Larry G. Sneddon; R. Thomas Baker

    2013-01-13

    Effective storage of hydrogen presents one of the most significant technical gaps to successful implementation of the hydrogen economy, particularly for transportation applications. Amine boranes, such as ammonia borane H3NBH3 and ammonia triborane H3NB3H7, have been identified as promising, high-capacity chemical hydrogen storage media containing potentially readily released protic (N-H) and hydridic (B-H) hydrogens. At the outset of our studies, dehydrogenation of ammonia borane had been studied primarily in the solid state, but our DOE sponsored work clearly demonstrated that ionic liquids, base-initiators and/or metal-catalysts can each significantly increase both the rate and extent of hydrogen release from amine boranes under moderate conditions. Our studies also showed that depending upon the activation method, hydrogen release from amine boranes can occur by very different mechanistic steps and yield different types of spent-fuel materials. The fundamental understanding that was developed during this grant of the pathways and controlling factors for each of these hydrogen-release mechanisms is now enabling continuing discovery and optimization of new chemical-hydride based hydrogen storage systems.

    A four-compartment anaerobic baffled reactor (ABR) incorporated with membrane-less biocatalyzed electrolysis system (BES) was tested for the treatment of azo dye (alizarin yellow R, AYR) wastewater (AYR, 200 mg L(-1); glucose, 1000 mg L(-1)). The ABR-BES was operated without and with external power supply to examine AYR reduction process and reductive intermediates with different external voltages (0.3, 0.5 and 0.7 V) and hydraulic retention times (HRT: 8, 6 and 4h). The decolorization efficiency in the ABR-BES (8h HRT, 0.5 V) was higher than that in ABR-BES without electrolysis, i.e. 95.1 ± 1.5% versus 86.9 ± 6.3%. Incorporation of BES with ABR accelerated the consumption of VFAs (mainly acetate) and attenuated biogas (methane) production. Higher power supply (0.7 V) enhanced AYR decolorization efficiency (96.4 ± 1.8%), VFAs removal, and current density (24.1 Am(-3) TCV). Shorter HRT increased volumetric AYR decolorization rates, but decreased AYR decolorization efficiency. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2017-06-01

    The present paper focuses on studying a new methodology to predict the overall behavior of buildings, which combines two simulation tools: COMSOL Multiphysicsand TRNSYS. The first software is used for the modeling of heat, air and moisture transfer in multilayer porous walls (HAM model—Heat, Air and Moisture transfer), and the second is used to simulate the hygrothermal behavior of the building (BES model—Building Energy Simulation). The combined software applications dynamically solve the mass and energy conservation equations of the two physical models. In this context, a coupled heat, air and mass transfer model is proposed. This model incorporates simultaneously the diffusive, convective and conductive effects on the building elements. Heat transfer is considered in the strongly coupled situation where the mass and heat flux are temperature, vapor pressure and total pressure dependents. The model input parameters are evaluated experimentally through the development of various experimental prototypes in the laboratory. Thereafter, an experimental setup has been established in order to evaluate the hygrothermal process of building walls. The experimental procedure consists to follow the temperature and relative humidity evolutions within the envelope thickness, submitted to controlled and fixed boundary conditions. Finally, using the developed experimental device, comparison between experimental data and numerical solution of the HAM-BES co-simulation platform was undertaken. Results showed good agreement with acceptable errors margins.

    Simultaneous assessment of the spectroscopic absorption signal of gas enclosed in a scattering medium and the corresponding optical path length of the probing light is demonstrated using a single setup. Sensitive gas absorption measurements are performed by a tunable diode laser using wavelength-modulation spectroscopy, while the path length is evaluated by the frequency-modulated cw technique commonly used in the field of telecommunication. Proof-of-principle measurements are demonstrated with water vapor as the absorbing gas and using polystyrene foam as an inhomogeneously scattering medium. The combination of these techniques opens up new possibilities for straightforward evaluation of gas presence and exchange in scattering media. © 2011 Optical Society of America

    Media, from television to the "new media" (including cell phones, iPads, and social media), are a dominant force in children's lives. Although television is still the predominant medium for children and adolescents, new technologies are increasingly popular. The American Academy of Pediatrics continues to be concerned by evidence about the potential harmful effects of media messages and images; however, important positive and prosocial effects of media use should also be recognized. Pediatricians are encouraged to take a media history and ask 2 media questions at every well-child visit: How much recreational screen time does your child or teenager consume daily? Is there a television set or Internet-connected device in the child's bedroom? Parents are encouraged to establish a family home use plan for all media. Media influences on children and teenagers should be recognized by schools, policymakers, product advertisers, and entertainment producers. Copyright © 2013 by the American Academy of Pediatrics.

  4. Reservoir simulation with imposed flux continuity conditions on heterogeneous and anisotropic media for general geometries, and the inclusion of hysteresis in forward modeling

    Energy Technology Data Exchange (ETDEWEB)

    Eigestad, Geir Terje

    2003-04-01

    The thesis is divided into two main parts. Part I gives an overview and summary of the theory that lies behind the flow equations and the discretization principles used in the work. Part II is a collection of research papers that have been written by the candidate (in collaboration with others). The main objective of this thesis is the discretization of an elliptic PDE which describes the pressure in a porous medium. The porous medium will in general be described by permeability tensors which are heterogeneous and anisotropic. In addition, the geometry is often complex for practical applications. This requires discretization approaches that are suited for the problems in mind. The discretization approaches used here are based on imposed flux and potential continuity, and will be discussed in detail in Chapter 3 of Part I. These methods are called Multi Point Flux Approximation Methods, and the acronym MPFA will be used for them. Issues related to these methods will be the main issue of this thesis. The rest of this thesis is organised as follows: Part I: Chapter 1 gives a brief overview of the physics and mathematics behind reservoir simulation. The standard mass balance equations are presented, and we try to explain what reservoir simulation is. Some standard discretization s methods are briefly discussed in Chapter 2. The main focus in Part I is on the MPFA discretization approach for various geometries, and is given in Chapter 3. Some details may have been left out in the papers of Part II, and the section serves both as a summary of the discretization method(s), as well as a more detailed description than what is found in the papers. In Chapter 4, extensions to handle time dependent and nonlinear problems are discussed. Some of the numerical examples presented in Part II deal with two phase flow, and are based on the extension given in this chapter. Chapter 5 discusses numerical results that have been obtained for the MPFA methods for elliptic problems, and

    Femtoscopy is a tool to study the space-time evolution of hot and dense matter during high energy collision by using two-particle correlations. The femtoscopic and flow measurements at RHIC and LHC energies are well reproduced by the hydrodynamics models that contains equation of state (EoS) with crossover type transition from Quark-Gluon Plasma to hadron gas phase. Similar studies where performed at AGS and SPS accelerators and was performed in Beam Energy Scan (BES) program at Relativistic Heavy Ion Collider for exploring phase diagram of QCD matter. I present the femtoscopic observables calculated for Au-Au collisions at √sNN = 7:7 - 62:4 GeV calculated from viscous hydro + cascade model vHLLE+UrQMD with two types of EoSs - one that correspond to 1st order phase transition (PT) and second that correspond to crossover PT. I also discuss perspectives of femtoscopic measurements at NICA energy scale √sNN = 4 - 11 GeV.1

    A novel conductive membrane with Fe/Mn/C/F/O elements is developed, it functions as the catalytic cathode of MFC and the antifouling filter of MBR simultaneously, in a newly designed integrated wastewater treatment system, without proton exchange membrane (PEM). The optimal conductive membrane is characterized using SEM-EDX, XRD and XPS. BET and porous structure analysis of the grounded membrane material indicate a narrow and small pore size (2-7 nm). The membrane surface is rich in Fe species (Fe - Fe2O3- Fe3O4) and manganese oxide (MnO2). Its characteristics such as excellent electro-chemical oxygen reduction reaction (ORR) activity, high clear water flux (>240 L/(m2·h)) and better antifouling filtration performance are further confirmed. The new system features bio-electrochemical system (BES) and integrates bio-filtration (trickling filter and air contact oxidation bed) and proton transfer through quartz sand chamber (QSC) which eliminates the use of expensive proton exchange membrane. The system removes chemical oxygen demand (>97.4%), ammonia nitrogen (>96.7%), total phosphorus (>98.0%) effectively, and it simultaneously generates electricity (446 mW/m3). The low cost and high performances, economic and advantageous system has good compatibility with existing wastewater treatment facilities and a wide application prospect.

    The American Academy of Pediatrics recognizes that exposure to mass media (eg, television, movies, video and computer games, the Internet, music lyrics and videos, newspapers, magazines, books, advertising) presents health risks for children and adolescents but can provide benefits as well. Media education has the potential to reduce the harmful effects of media and accentuate the positive effects. By understanding and supporting media education, pediatricians can play an important role in reducing harmful effects of media on children and adolescents.

    Cantor, J

    2000-08-01

    Research on the effects of media violence is not well understood by the general public. Despite this fact, there is an overwhelming consensus in the scientific literature about the unhealthy effects of media violence. Meta-analyses show that media-violence viewing consistently is associated with higher levels of antisocial behavior, ranging from the trivial (imitative violence directed against toys) to the serious (criminal violence), with many consequential outcomes in between (acceptance of violence as a solution to problems, increased feelings of hostility, and the apparent delivery of painful stimulation to another person). Desensitization is another well-documented effect of viewing violence, which is observable in reduced arousal and emotional disturbance while witnessing violence, the reduced tendency to intervene in a fight, and less sympathy for the victims of violence. Although there is evidence that youth who are already violent are more likely to seek out violent entertainment, there is strong evidence that the relationship between violence viewing and antisocial behavior is bidirectional. There is growing evidence that media violence also engenders intense fear in children which often lasts days, months, and even years. The media's potential role in solutions to these problems is only beginning to be explored, in investigations examining the uses and effects of movie ratings, television ratings, and the V-chip, and the effects of media literacy programs and public education efforts. Future research should explore important individual differences in responses to media violence and effective ways to intervene in the negative effects.

    There are two different types of media bias. One bias, which we refer to as ideology, reflects a news outlet's desire to affect reader opinions in a particular direction. The second bias, which we refer to as spin, reflects the outlet's attempt to simply create a memorable story. We examine competition among media outlets in the presence of these biases. Whereas competition can eliminate the effect of ideological bias, it actually exaggerates the incentive to spin stories.

    2013-07-09

    The present thesis deals with two experiments, which perform on the field of the hadron spectroscopy fundamental research. These are the existing BES III experiment, from which data from charmonium decay are analyzed and the future PANDA experiment, for which in this thesis the readout of the forward end cap of the electromagnetic calorimeter is developed. In the first part the radiative decays of ψ(2S) and J/ψ into γ(π{sup +}π{sup -}η) are analyzed for the study of the η(1405) meson. This state is considered as possible glueball candidate, because among others the pseudoscalar-meson nonet with the η(1405), η(1295), and η(1475) is overoccupied by one particle and other experiments assign to the η(1405) a large gluonic contribution. The production of the η(1475) can, as confirmed by other experiments, ot be observed in the decay into π{sup +}π{sup -}η.The η(1295) however is identified in the framework of a partial-wave analysis in the decay J/ψ→γπ{sup +}π{sup -}η. This succeeded previously only in the DM2 experiment, indeed with distinctly lower statistics and corresponding uncertainties. A possible solution of the problem of the overoccupation, the non-existence of the η(1295), cannot be confirmed by the results presented in this thesis. Furthermore the branching ratios of different decays are determined. The high event-rate allows to determine some decay probabilities for the first time respectively clearly more precisely. The partial waves contributing in the decay J/ψ→γπ{sup +}π{sup -}η can be determined by a mass-independent partial-wave analysis and brought into connection with known resonances. In the second part of the thesis the development and optimization of the photodetector-preamplifier units used for the readout of the forward end cap of the electromagnetic calorimeter are shown. A manifold of these detector-units were produced for a prototype of the forward end cap and tested in subsequent test-beam times under real

    Full Text Available This paper focuses on the continuities, rather than the ruptures, between digital television and past media forms. It situates the metaphor of “streaming” in contrast to and connection with previous fluid metaphors that have been used to describe different models of media transmission. From the early use of aqueous vocabulary that shaped popular and scientific understandings of electricity transmission to the seminal studies of mass communication concerning the flows of information, images of fluidity have long shaped cultural understandings of the inner logics of media infrastructures. Building on the work of media archaeologist Erkki Huhtamo, I approach these metaphors as “recurrent topoi” in media culture.

    Based on the shearlet transform we present a general construction of continuous tight frames for L2(ℝ2) from any sufficiently smooth function with anisotropic moments. This includes for example compactly supported systems, piecewise polynomial systems, or both. From our earlier results in Grohs (Technical report, KAUST, 2009) it follows that these systems enjoy the same desirable approximation properties for directional data as the previous bandlimited and very specific constructions due to Kutyniok and Labate (Trans. Am. Math. Soc. 361:2719-2754, 2009). We also show that the representation formulas we derive are in a sense optimal for the shearlet transform. © 2010 Springer Science+Business Media, LLC.

    In a previous survey we revealed uncertainty among responders about (a) whether or not to perform hemodialysis in patients with severely reduced renal function who had received contrast medium; and (b) when to perform hemodialysis in patients on regular treatment with hemodialysis or continuous ambulatory dialysis who received contrast medium. Therefore, the Contrast Media Safety Committee of The European Society of Urogenital Radiology decided to review the literature and to issue guidelines. The committee performed a Medline search. Based on this, a report and guidelines were prepared. The report was discussed at the Ninth European Symposium on Urogenital Radiology in Genoa, Italy. Hemodialysis and peritoneal dialysis safely remove both iodinated and gadolinium-based contrast media. The effectiveness of hemodialysis depends on many factors including blood and dialysate flow rate, permeability of dialysis membrane, duration of hemodialysis and molecular size, protein binding, hydrophilicity, and electrical charge of the contrast medium. Generally, several hemodialysis sessions are needed to removal all contrast medium, whereas it takes 3 weeks for continuous ambulatory dialysis to remove the agent completely. There is no need to schedule the dialysis in relation to the injection of iodinated or MR contrast media or the injection of contrast agent in relation to the dialysis program. Hemodialysis does not protect poorly functioning kidneys against contrast-medium-induced nephrotoxicity. Simple guidelines are given. (orig.)

    The impact of the mass media on woman's status was addressed at two 1995 conferences: the Fourth World Conference on Women, held in Beijing, China, and the Congress of the World Association for Christian Communication, held in Puebla, Mexico. The globalization process facilitated by the mass media has served to increase the power of patriarchy, with no advantages to the cause of women's rights. Coverage of popular movements has been suppressed out of deference to male-controlled governments. Coverage of the Beijing Conference highlighted celebrities and personal stories, to the exclusion of the economic and political issues under debate. Television has commodified women, reinforcing their oppression. On the other hand, the alternative media, which tend to be decentralized, democratic, low-cost, and low in technology, are presenting women as subjects rather than objects and deconstructing gender stereotypes. Of concern, however, is the tendency of computer technology to widen the gap between social classes and developed and developing countries. Women must use information networks to disseminate information on women's rights and strengthen the links between women throughout the world.

  13. Social media as communicative genres

    Directory of Open Access Journals (Sweden)

    Stine Lomborg

    2011-08-01

    Full Text Available As a focus of study, ‘social media’ tend to lack definitional clarity and grounding in theories of media and text. This paper establishes and discusses a conceptual framework for defining social media as communicative genres, constituted by the interplay between interactive functionalities configured at the software level and the invocation and appropriation of various software functionalities to achieve specific purposes in and through users’ actual communicative practices. I suggest that social media might be seen as particularly dynamic genres, subject to continuous disruption and uncertainty,owing to their deinstitutionalised and participatory character, and the shifting roles of producers and recipients in the networks and conversations that make up social media content.

  14. Continuation calculus

    Full Text Available Programs with control are usually modeled using lambda calculus extended with control operators. Instead of modifying lambda calculus, we consider a different model of computation. We introduce continuation calculus, or CC, a deterministic model of computation that is evaluated using only head reduction, and argue that it is suitable for modeling programs with control. It is demonstrated how to define programs, specify them, and prove them correct. This is shown in detail by presenting in CC a list multiplication program that prematurely returns when it encounters a zero. The correctness proof includes termination of the program. In continuation calculus we can model both call-by-name and call-by-value. In addition, call-by-name functions can be applied to call-by-value results, and conversely.

  18. Managing Media: Segmenting Media Through Consumer Expectancies

    Directory of Open Access Journals (Sweden)

    Matt Eastin

    2014-04-01

    Full Text Available It has long been understood that consumers are motivated to media differently. However, given the lack of comparative model analysis, this assumption is without empirical validation, and thus, the orientation of segmentation from a media management perspective is without motivational grounds. Thus, evolving the literature on media consumption, the current study develops and compares models of media segmentation within the context of use. From this study, six models of media expectancies were constructed so that motivational differences between media (i.e., local and national newspapers, network and cable television, radio, and Internet could be observed. Utilizing higher order statistical analyses the data indicates differences across a model comparison approach for media motivations. Furthermore, these differences vary across numerous demographic factors. Results afford theoretical advancement within the literature of consumer media consumption as well as provide media planners’ insight into consumer choices.

  19. Social media for lifelong learning.

    Science.gov (United States)

    Kind, Terry; Evans, Yolanda

    2015-04-01

    Learning is ongoing, and can be considered a social activity. In this paper we aim to provide a review of the use of social media for lifelong learning. We start by defining lifelong learning, drawing upon principles of continuous professional development and adult learning theory. We searched Embase and MEDLINE from 2004-2014 for search terms relevant to social media and learning. We describe examples of lifelong learners using social media in medical education and healthcare that have been reported in the peer-reviewed literature. Medical or other health professions students may have qualities consistent with being a lifelong learner, yet once individuals move beyond structured learning environments they will need to recognize their own gaps in knowledge and skills over time and be motivated to fill them, thereby incorporating lifelong learning principles into their day-to-day practice. Engagement with social media can parallel engagement in the learning process over time, to the extent that online social networking fosters feedback and collaboration. The use of social media and online networking platforms are a key way to continuously learn in today's information sharing society. Additional research is needed, particularly rigorous studies that extend beyond learner satisfaction to knowledge, behaviour change, and outcomes.

    2012-09-30

    As technological advances continue to expand connectivity and communication, the number of patients and nurses engaging in social media increases. Nurses play a significant role in identification, interpretation, and transmission of knowledge and information within healthcare. Social media is a platform that can assist nursing faculty in helping students to gain greater understanding of and/or skills in professional communication; health policy; patient privacy and ethics; and writing competencies. Although there are barriers to integration of social media within nursing education, there are quality resources available to assist faculty to integrate social media as a viable pedagogical method. This article discusses the background and significance of social media tools as pedagogy, and provides a brief review of literature. To assist nurse educators who may be using or considering social media tools, the article offers selected examples of sound and pedagogically functional use in course and program applications; consideration of privacy concerns and advantages and disadvantages; and tips for success.

    2000-06-01

    The way in which the North American print media are representing global warming was the focus of this paper. It was suggested that the way in which the media presents the issue and proposed responses to it, will influence how the public and decision-makers perceive and respond to the problem. This paper also presented examples demonstrating how nature and humanity's relationship to nature are being presented and what types of responses to global warming are being presented. The issue of who is responsible for acting to prevent or mitigate climate change was also discussed. It was shown that media narratives of global warming are not just stories of scientists debating the existence of global warming, but that they now largely accept global warming as a reality. However, the media continue to construct the problem in narrow technical, economic and anthropocentric terms. Mass media interpretation of global warming offer up a limited selection of problem definitions, reasons for acting and ways of addressing the problem. It was cautioned that this approach will likely promote futility, denial and apathy on the part of the public. 21 refs.

    This article uses grounded theory methodology to analyze in-depth interviews conducted with mourners who used social networking sites during bereavement. The social media mourning (SMM) model outlines how social networking sites are used to grieve using one or more of the following: (a) one-way communication, (b) two-way communication, and (c) immortality communication. The model indicates causal conditions of SMM: (a) sharing information with family or friends and (sometimes) beginning a dialog, (b) discussing death with others mourning, (c) discussing death with a broader mourning community, and (d) commemorating and continuing connection to the deceased. The article includes actions and consequences associated with SMM and suggests several ways in which SMM changes or influences the bereavement process.

Internet technology has made communication much easier and less expensive. It has attracted many people and has penetrated into people’s daily lives. The mass media also have accepted the internet. Almost all forms of traditional media (old media in local media, such as radio, television, and newspaper have extended their work into this new field. The internet and the World Wide Web have both significantly influenced modern journalism.

    Full Text Available The 21st century has marked an unprecedented advancement of new media. New media has become so pervasive that it has penetrated into every aspect of our society. New media literacy plays an essential role for any citizen to participate fully in the 21st century society. Researchers have documented that literacy has evolved historically from classic literacy (reading-writing-understanding to audiovisual literacy to digital literacy or information literacy and recently to new media literacy. A review of literature on media literacy reveals that there is a lack of thorough analysis of unique characteristics of new media and its impacts upon the notion of new media literacy. The purpose of the study is to unpack new media literacy and propose a framework for a systematic investigation of new media literacy.

    Understanding the family dynamic surrounding media use is crucial to our understanding of media effects, policy development, and the targeting of individuals and families for interventions to benefit child health and development. The Families, Parenting, and Media Workgroup reviewed the relevant research from the past few decades. We find that child characteristics, the parent-child relationship, parental mediation practices, and parents' own use of media all can influence children's media use, their attitudes regarding media, and the effects of media on children. However, gaps remain. First, more research is needed on best practices of parental mediation for both traditional and new media. Ideally, this research will involve large-scale, longitudinal studies that manage children from infancy to adulthood. Second, we need to better understand the relationship between parent media use and child media use and specifically how media may interfere with or strengthen parent-child relationships. Finally, longitudinal research on how developmental processes and individual child characteristics influence the intersection between media and family life is needed. The majority of children's media use takes place within a wider family dynamic. An understanding of this dynamic is crucial to understanding child media use as a whole.

    Full Text Available Dans un champ magnétique hétérogène, le signal RMN de précession libre (FID suit une évolution gaussienne. Le traitement du signal par une méthode discrète peut donner des composantes qui ne correspondent pas à un état physique réel. Par contre l'utilisation d'une méthode de déconvolution continue nous a donné des résultats quantitatifs tout à fait satisfaisants permettant de déterminer les distributions de temps de relaxation correspondant à des états intermédiaires entre les phases solides et liquides. La RMN du domaine du temps peut ainsi être considérée comme une méthode analytique complémentaire des techniques habituellement utilisées pour l'étude de composés complexes hétérogènes ATD, ACD, isothermes de sorption, etc. In a heterogeneous magnetic field, the freely precessing NMR signal (FID describes a Gaussian curve. Processing the signal using a discrete method can give rise to components that do not correspond to a real physical state. However, with a continuous deconvolution method, which gives quite satisfactory quantitative results, it is possible to determine the distributions of relaxation times that correspond to intermediate states between solid and liquid phases. Time-dependent NMR can thus be used to supplement the usual analytical methods, such as DTA, DCA and sorption isotherms, for studying complex heterogeneous compounds.

    Full Text Available Film media is a new media to communicate. However, the communication way in this movie is different from other media communication visual. Continuity is a crucial element in communicating through visual media, and sometimes continuity in a film is parted in a scene. The cause of losing continuity needs to be observed more, so there will be a method to anticipate losing continuity of a film in pre-production stage or in preparation stage before actual shooting. The data gained from students’ assignments in ‘Cinematography for Animation’ subject, which close to problem formulation. After the data is gained and compared, there will be experiment using simulation towards application software 3D to find alternative about continuity. The result covers the shooting way to keep continuity and a brave preparation in pre-production stage or before shooting.

    Social media enable millions of users to create and disseminate narratives about organizations that increase their public exposure and shape public perceptions. In this paper, we draw on the sociology of news production and research on computer-mediated communication to discuss how different...... motivational drivers and contextual conditions associated with the formation of narratives in traditional news media and social media influence their content, diffusion, and impact significantly.

    Mass media exposure has been associated with an increased risk of eating pathology. It is unknown whether indirect media exposure--such as the proliferation of media exposure in an individual's social network--is also associated with eating disorders. To test hypotheses that both individual (direct) and social network (indirect) mass media exposures were associated with eating pathology in Fiji. We assessed several kinds of mass media exposure, media influence, cultural orientation and eating pathology by self-report among adolescent female ethnic Fijians (n=523). We fitted a series of multiple regression models of eating pathology, assessed by the Eating Disorder Examination Questionnaire (EDE-Q), in which mass media exposures, sociodemographic characteristics and body mass index were entered as predictors. Both direct and indirect mass media exposures were associated with eating pathology in unadjusted analyses, whereas in adjusted analyses only social network media exposure was associated with eating pathology. This result was similar when eating pathology was operationalised as either a continuous or a categorical dependent variable (e.g. odds ratio OR=1.60, 95% CI 1.15-2.23 relating social network media exposure to upper-quartile EDE-Q scores). Subsequent analyses pointed to individual media influence as an important explanatory variable in this association. Social network media exposure was associated with eating pathology in this Fijian study sample, independent of direct media exposure and other cultural exposures. Findings warrant further investigation of its health impact in other populations.

  17. Social Media and Distribution Studies

    Directory of Open Access Journals (Sweden)

    Josh Braun

    2015-04-01

    Full Text Available Social media increasingly trouble our traditional distinctions between distribution concerns on the one hand and editorial concerns on the other. Sites like Facebook and reddit simultaneously serve as distribution platforms, circulating messages addressed to individuals and publics, and as mechanical editors, deciding algorithmically which posts and topics warrant inclusion in the continuous and often overwhelming feed of information delivered to each of our screens. Recent controversies surrounding the manner in which social media companies develop and test software and editorial strategies for curating content may have brought this editor–distributor duality into sharp relief in ways that feel new and at times uncomfortable. But as a number of critical scholars—most notably Michael Warner—have illustrated, the boundary between editorial and distribution concerns has always been highly porous. Framing social media as centers of reflexive distribution not only opens up sociologically interesting questions about how such distribution infrastructures are forged but also about how they affect the “concatenation of texts through time” and the sense of shared attention and imagined community that enable public discourse. This essay argues that the emerging field of “distribution studies” is a compelling lens for the considering social media and their place in society and public life.

    The growing popularity and use of social media tools such as Facebook, YouTube, Twitter, blogging, and wikis have led to a social media revolution. Given this widespread influence, it is important for educators, administrators, and technologists to understand the risks of using social media in the classroom and workplace. To investigate popular social media sites and their effect on radiologic technology education and business practices. A comprehensive search of literature was performed to examine social media and its applications in education, health care, and business. Social media use is on the rise, affecting all aspects of mainstream society. Leaders in the radiologic sciences should be familiar with social media and cognizant of its risks. Future studies regarding social media use in the radiologic sciences are necessary to determine its effect on the radiologic science community. ©2011 by the American Society of Radiologic Technologists.

    2008-01-01

    American youth are awash in media. They have television sets in their bedrooms, personal computers in their family rooms, and digital music players and cell phones in their backpacks. They spend more time with media than any single activity other than sleeping, with the average American eight- to eighteen-year-old reporting more than six hours of daily media use. The growing phenomenon of "media multitasking"--using several media concurrently--multiplies that figure to eight and a half hours of media exposure daily. Donald Roberts and Ulla Foehr examine how both media use and media exposure vary with demographic factors such as age, race and ethnicity, and household socioeconomic status, and with psychosocial variables such as academic performance and personal adjustment. They note that media exposure begins early, increases until children begin school, drops off briefly, then climbs again to peak at almost eight hours daily among eleven- and twelve-year-olds. Television and video exposure is particularly high among African American youth. Media exposure is negatively related to indicators of socioeconomic status, but that relationship may be diminishing. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance. Roberts and Foehr also review evidence pointing to the existence of a digital divide--variations in access to personal computers and allied technologies by socioeconomic status and by race and ethnicity. The authors also examine how the recent emergence of digital media such as personal computers, video game consoles, and portable music players, as well as the media multitasking phenomenon they facilitate, has increased young people's exposure to media messages while leaving media use time largely unchanged. Newer media, they point out, are not displacing older media but are being used in concert with them. The authors note which young people are more or less likely to use several

    2008-02-15

    We report a new continuous electrodeionization cell with electrostatically shielded concentrate compartments or electrochemical Faraday cages formed by porous electronically and ionically conductive media, instead of permselective ion exchange membranes. Due to local elimination of the applied electric field within the compartments, they electrostatically retain the incoming ions and act as 'electrostatic ion pumps' or 'ion traps' and therefore concentrate compartments. The porous media are chemically and thermally stable. Electrodeionization or electrodialysis cells containing such concentrate compartments in place of ion exchange membranes can be used to regenerate ion exchange resins and produce deionized water, to purify industrial effluents and desalinate brackish or seawater. The cells can work by polarity reversal without any negative impact to the deionization process. Because the electronically and ionically active media constituting the electrostatically shielded concentrate compartments are not permselective and coions are not repelled but can be swept by the migrating counterions, the cells are not affected by the known membrane associated limitations, such as concentration polarization or scaling and show an increased current efficiency.

  9. Understanding Social Media Logic

    Directory of Open Access Journals (Sweden)

    José van Dijck

    2013-08-01

    Full Text Available Over the past decade, social media platforms have penetrated deeply into the mech­anics of everyday life, affecting people's informal interactions, as well as institutional structures and professional routines. Far from being neutral platforms for everyone, social media have changed the conditions and rules of social interaction. In this article, we examine the intricate dynamic between social media platforms, mass media, users, and social institutions by calling attention to social media logic—the norms, strategies, mechanisms, and economies—underpin­ning its dynamics. This logic will be considered in light of what has been identified as mass me­dia logic, which has helped spread the media's powerful discourse outside its institutional boundaries. Theorizing social media logic, we identify four grounding principles—programmabil­ity, popularity, connectivity, and datafication—and argue that these principles become increas­ingly entangled with mass media logic. The logic of social media, rooted in these grounding principles and strategies, is gradually invading all areas of public life. Besides print news and broadcasting, it also affects law and order, social activism, politics, and so forth. Therefore, its sustaining logic and widespread dissemination deserve to be scrutinized in detail in order to better understand its impact in various domains. Concentrating on the tactics and strategies at work in social media logic, we reassess the constellation of power relationships in which social practices unfold, raising questions such as: How does social media logic modify or enhance ex­isting mass media logic? And how is this new media logic exported beyond the boundaries of (social or mass media proper? The underlying principles, tactics, and strategies may be relat­ively simple to identify, but it is much harder to map the complex connections between plat­forms that distribute this logic: users that employ them, technologies that

    Full Text Available This article considers copyright knowledge and skills as a new literacy that can be developed through the application of digital media literacy pedagogies. Digital media literacy is emerging from more established forms of media literacy that have existed in schools for several decades and have continued to change as the social and cultural practices around media technologies have changed. Changing requirements of copyright law present specific new challenges for media literacy education because the digitisation of media materials provides individuals with opportunities to appropriate and circulate culture in ways that were previously impossible. This article discusses a project in which a group of preservice media literacy educators were introduced to knowledge and skills required for the productive and informed use of different copyrights frameworks. The students’ written reflections and video production responses to a series of workshops about copyright are discussed, as are the opportunities and challenges provided by copyright education in preservice teacher education.

    The International Year of Astronomy New Media Working Group (IYA NMWG) has a singular mission: To flood the Internet with ways to learn about astronomy, interact with astronomers and astronomy content, and socially network with astronomy. Within each of these areas, we seek to build lasting programs and partnerships that will continue beyond 2009. Our weapon of choice is New Media. It is often easiest to define New Media by what it is not. Television, radio, print and their online redistribution of content are not New Media. Many forms of New Media start as user provided content and content infrastructures that answer that individual's creative whim in a way that is adopted by a broader audience. Classic examples include Blogs and Podcasts. This media is typically distributed through content specific websites and RSS feeds, which allow syndication. RSS aggregators (iTunes has audio and video aggregation abilities) allow subscribers to have content delivered to their computers automatically when they connect to the Internet. RSS technology is also being used in such creative ways as allowing automatically updating Google-maps that show the location of someone with an intelligent GPS system, and in sharing 100 word microblogs from anyone (Twitters) through a single feed. In this poster, we outline how the IYA NMWG plans to use New Media to reach target primary audiences of astronomy enthusiasts, image lovers, and amateur astronomers, as well as secondary audiences, including: science fiction fans, online gamers, and skeptics.

    Full Text Available The author grounds her research and the latter analysis on continually conducted daily press-clipping of seven main printed daily newspapers and two main electronic media in Serbia, within the three years period (2009 - 2011. An analysis of media reports on gender based violence, with particular focus on the most frequent domestic violence cases within the two years period, 2010 to 2011 is presented. As the best of media reports on gender based violence, the author stressed out its „whistle blower“ role - media are the main source of information on cases, dimensions and forms of gender based violence. Also the worse moments of media reporting in the mentioned period are presented - when the violence was justified or when reality is deformed by presenting these cases as romantic love stories. For example, in 2010 the worst was reporting on the „Pajčin/Kapisoda“ case, while in 2011 it was the „Ponjiger“ case.

    Reporting of astronomical discoveries and events in the news media continues to expand to satisfy a seemingly voracious public interest. New telescopes, instruments, and facilities both up in space and on the ground, provide unique opportunities for media outreach on what scientists are accomplishing. And, new media such as website news providers, high-definition television, and video news walls help to fuel the growing activity. Ever since Tycho Brahe operated his own printing press, astronomers have striven to document their accomplishments for the wider world. In recent years, astronomers' media outreach has been successful in reaching the mass television audience through successful efforts at animation and scientific visualization, and through dramatic images acquired by some facilities, such as the solar physics satellites and ground observatories.

    Social media includes many different forms of technology including online forums, blogs, microblogs (i.e. Twitter), wikipedias, video blogs, social networks and podcasting. The use of social media has grown exponentially and time spent on social media sites now represents one in five minutes spent online. Concomitant with this online growth, there has been an inverse trajectory in direct face-to-face patient-provider moments, which continue to become scarcer across the spectrum of health care. In contrast to standard forms of engagement and education, social media has advantages to include profound reach, immediate availability, an archived presence and broad accessibility. Our opportunity as health care providers to partner with our patients has never been greater, yet all too often we allow risk averse fears to limit our ability to truly leverage our good content effectively to the online community. This risk averse behavior truly limits our capacity to effectively engage our patients where they are--online.

    Use of social media by doctors and medical students is common and growing. Although professional standards and codes of ethics that govern the behaviour of medical practitioners in Australia and New Zealand do not currently encompass social media, these codes need to evolve, because professional standards continue to apply in this setting. Inappropriate use of social media can result in harm to patients and the profession, including breaches of confidentiality, defamation of colleagues or employers, and violation of doctor-patient boundaries. The professional integrity of doctors and medical students can also be damaged through problematic interprofessional online relationships, and unintended exposure of personal information to the public, employers or universities. Doctors need to exercise extreme care in their use of social media to ensure they maintain professional standards.

    To review updates in how abortion care is depicted and analysed though various media outlets: news, television, film, and social media. A surge in recent media-related abortion research has recognized several notable and emerging themes: abortion in the news media is often inappropriately sourced and politically motivated; abortion portrayal in US film and television is frequently misrepresented; and social media has a new and significant role in abortion advocacy. The portrayal of abortion onscreen, in the news, and online through social media has a significant impact on cultural, personal, and political beliefs in the United States. This is an emerging field of research with wide spread potential impact across several arenas: medicine, policy, public health.

    Schooler, C; Flora, J A

    1996-01-01

    In this review, we focus our discussion on studies examining effects on children and young adults. We believe that the current epidemic of youth violence in the United States justifies a focus on this vulnerable segment of society. We consider media effects on individual children's behaviors, such as imitating aggressive acts. In addition, we examine how the media influence young people's perceptions of norms regarding interpersonal relationships. Next, we assess mass media effects on societal beliefs, or what children and adolescents think the "real world" is like. We suggest these media influences are cumulative and mutually reinforcing, and discuss the implications of repeated exposure to prominent and prevalent violent media messages. Finally, we catalog multiple intervention possibilities ranging from education to regulation. From a public health perspective, therefore, we evaluate the effects that pervasive media messages depicting violence have on young people and present multiple strategies to promote more healthful outcomes.

  12. Genre in media production

    Hanne Bruun

    2011-08-01

    Full Text Available How do we explain changes in media genres? Are they the result of economic, technological or other kinds of structural forces; or are they the result of the change-producing agency of the media producers? And how are changes in media texts connected to contextual conditions for media production on micro-, meso- or macro levels? This article suggests that a theoretical approach using a pragmatic and socio-cognitive understanding of genre will help us to address these questions. This approach can highlight the interplay between human agency and different kinds of structural forces involved in specific professional media production cultures. Furthermore, it has the potential to integrate media texts and especially the micro- and meso levels of production. Using lessons learned and findings from my recent production study of Danish television satire, the article will argue three major methodological as well as knowledge-producing advantages of a genre approach.

Technology influences children of all ages. Seventy-five percent of teenagers own cell phones, with 25% using them for social media. Technology can lead to an increase in skills and social benefits but there is also the potential for harm such as sexting, cyberbullying, privacy issues, and Internet addiction, all of which can affect health.

    Cain, Matthew S; Leonard, Julia A; Gabrieli, John D E; Finn, Amy S

    2016-12-01

    Media use has been on the rise in adolescents overall, and in particular, the amount of media multitasking-multiple media consumed simultaneously, such as having a text message conversation while watching TV-has been increasing. In adults, heavy media multitasking has been linked with poorer performance on a number of laboratory measures of cognition, but no relationship has yet been established between media-multitasking behavior and real-world outcomes. Examining individual differences across a group of adolescents, we found that more frequent media multitasking in daily life was associated with poorer performance on statewide standardized achievement tests of math and English in the classroom, poorer performance on behavioral measures of executive function (working memory capacity) in the laboratory, and traits of greater impulsivity and lesser growth mindset. Greater media multitasking had a relatively circumscribed set of associations, and was not related to behavioral measures of cognitive processing speed, implicit learning, or manual dexterity, or to traits of grit and conscientiousness. Thus, individual differences in adolescent media multitasking were related to specific differences in executive function and in performance on real-world academic achievement measures: More media multitasking was associated with poorer executive function ability, worse academic achievement, and a reduced growth mindset.

    1997-01-01

    Costs, market fragmentation, and new media channels that let customers bypass advertisements seem to be in league against the old ways of marketing. Relying on mass media campaigns to build strong brands may be a thing of the past. Several companies in Europe, making a virtue of necessity, have come up with alternative brand-building approaches and are blazing a trail in the post-mass-media age. In England, Nestlé's Buitoni brand grew through programs that taught the English how to cook Italian food. The Body Shop garnered loyalty with its support of environmental and social causes. Cadbury funded a theme park tied to its history in the chocolate business. Häagen-Dazs opened posh ice-cream parlors and got itself featured by name on the menus of fine restaurants. Hugo Boss and Swatch backed athletic or cultural events that became associated with their brands. The various campaigns shared characteristics that could serve as guidelines for any company hoping to build a successful brand: senior managers were closely involved with brand-building efforts; the companies recognized the importance of clarifying their core brand identity; and they made sure that all their efforts to gain visibility were tied to that core identity. Studying the methods of companies outside one's own industry and country can be instructive for managers. Pilot testing and the use of a single and continuous measure of brand equity also help managers get the most out of novel approaches in their ever more competitive world.

    Social media platforms have revolutionized the way human beings communicate, yet there is little evidence describing how the plastic surgery community has adopted social media. In this article, the authors evaluate current trends in social media use by practicing plastic surgeons. An anonymous survey on the use of social media was distributed to members of the American Society of Plastic Surgeons. Prevalent patterns of social media implementation were elucidated. One-half of respondents were regular social media users. Reasons for using social media included the beliefs that incorporation of social media into medical practice is inevitable (56.7 percent), that they are an effective marketing tool (52.1 percent), and that they provide a forum for patient education (49 percent). Surgeons with a primarily aesthetic surgery practice were more likely to use social media. Most respondents (64.6 percent) stated that social media had no effect on their practice, whereas 33.8 percent reported a positive impact and 1.5 percent reported a negative impact. This study depicts current patterns of social media use by plastic surgeons, including motivations driving its implementation and impressions on its impact. Many feel that social media are an effective marketing tool that generates increased exposure and referrals. A small number of surgeons have experienced negative repercussions from social media involvement. Our study reveals the presence of a void. There is a definite interest among those surveyed in developing best practice standards and oversight to ensure ethical use of social media platforms throughout the plastic surgery community. Continuing discussion regarding these matters should be ongoing as our experience with social media in plastic surgery evolves.

  5. THE NEW LINK BETWEEN ART FESTIVAL AND THE MEDIA: THE ENGAGEMENT OF A MEDIA INSTITUTION IN SURABAYA ART FESTIVAL

    Directory of Open Access Journals (Sweden)

    Rachmah Ida

    2014-06-01

    Full Text Available This paper is an attempt to investigate a new trend of media behaviour and to study an aspect of the non-journalistic practice of the media organization in the society in post-authoritarian Indonesia. It discusses the engagement of a major local media institution in the organization of the Surabaya Art Festival in the early 2000s. The involvement of one wealthy media institution, Jawa Pos, in the organization of Surabaya’s cultural art festival, therefore, could shape a new model of relationship between the media and the society in the Indonesian context. Based on interviews with several existing and ex-members of the festival committees and media documentations, this study argues that the political economy of the media interest has played a major role in determining the contents and management of the festival, disregarding the need to exhibit the remarkable cultural richness and innovations. In this particular cultural event, the media has played a significant role in supplying the funding for the festival, and consequently, the media control the power in conceptualising the city’s annual art festival since then. Yet, when the owner of the media institution chose to stop supporting the funding to the festival organization, the result was palpable. After the withdrawal of this major media magnate from the festival organization, the continuation of the Surabaya Art Festival has become troublesome and susceptible.

    Social media - websites and other online tools called social networks - serve as a tool to connect people and organizations around topics of common interest. Social media platforms offer tremendous opportunity to engage quickly and sometimes in depth with many and diverse stakeholders as people have the ability to communicate back-and-forth from anywhere in the world. As increasing numbers of people receive their news and health information online, it is important to ensure content delivered through online resources is accessible to diverse target audiences. This chapter discusses a mid-sized health literacy nonprofit organizations' social media philosophy and tactics during the past 10 years, as both social media and health literacy strategies evolved continuously. The integration of social media in health literacy program content depends on the use with best evidence health literacy strategies, such as the use of plain language techniques. Strategy and technical considerations for the implementation and integration of social media within a health literate health communications model are discussed.

    2008-01-01

    Market trend data show that the media marketplace continues to rapidly evolve. Recent research shows that substantial portions of the U.S. media population are "new media" users. Today, more than ever before, media consumers are exposed to multiple media at the same point in time, encouraged to participate in media content generation, and challenged to learn, access, and use the new media that are continually entering the market. These media trends have strong implications for how consumers of health information access, process, and retain health-related knowledge. In this article we review traditional information processing models and theories of interpersonal and mass media access and consumption. We make several theory-based propositions for how traditional information processing and media consumption concepts will function as new media usage continues to increase. These propositions are supported by new media usage data from the Centers for Disease Control and Prevention's entry into the new media market (e.g., podcasting, virtual events, blogging, and webinars). Based on these propositions, we conclude by presenting both opportunities and challenges that public health communicators and marketers will face in the future.

    Millions of people all over the world are constantly sharing an extremely wide range of fascinating, quirky, funny, irrelevant and important content all at once. Even scientists are no strangers to this trend. Social media has enabled them to communicate their research quickly and efficiently throughout each corner of the world. But which social media platforms are they using to communicate this research and how are they using them? One thing is clear: the range of social media platforms that scientists are using is relatively vast and dependent on discipline and sentiment. While the future of social media is unknown, a combination of educated speculation and persuasive fact points to the industry's continual growth and influence. Thus, is that not only are scientists utilizing social media to communicate their research, they must. The ability to communicate to the masses via social media is critical to the distribution of scientific information amongst professionals in the field and to the general population.

    2016-06-01

    Healthcare professionals' use of social media platforms, such as blogs, wikis, and social networking web sites has grown considerably in recent years. However, few studies have explored the perspectives and experiences of physicians in adopting social media in healthcare. This article aims to identify the potential benefits and challenges of adopting social media by physicians and demonstrates this by presenting findings from a survey conducted with physicians. A qualitative survey design was employed to achieve the research goal. Semi-structured interviews were conducted with 24 physicians from around the world who were active users of social media. The data were analyzed using the thematic analysis approach. The study revealed six main reasons and six major challenges for physicians adopting social media. The main reasons to join social media were as follows: staying connected with colleagues, reaching out and networking with the wider community, sharing knowledge, engaging in continued medical education, benchmarking, and branding. The main challenges of adopting social media by physicians were also as follows: maintaining confidentiality, lack of active participation, finding time, lack of trust, workplace acceptance and support, and information anarchy. By revealing the main benefits as well as the challenges of adopting social media by physicians, the study provides an opportunity for healthcare professionals to better understand the scope and impact of social media in healthcare, and assists them to adopt and harness social media effectively, and maximize the benefits for the specific needs of the clinical community. © The Author(s) 2014.

    The International Year of Astronomy New Media Working Group (IYA NMWG) seeks to flood the Internet with ways to learn about astronomy and increase interaction among professionals, amateurs, and laypeople. Our primary audiences are amateur astronomers, astronomy and space enthusiasts, and image lovers, but secondary audiences include science fiction fans, online gamers, and skeptics. We aim to build lasting programs and partnerships that will continue beyond 2009. Our weapon of choice is New Media. New Media differ from traditional media (such as television, radio, and print) in their informality. Many forms of New Media start as user-provided content. New Media content-building infrastructures answer the content provider's creative whims, and New-Media content can be commented upon, shared, borrowed, adopted, edited, and re-posted by a broad audience. Classic examples of New Media include blogs and podcasts. This media is typically distributed through content-specific websites and RSS feeds, which allow individual Internet users to select preferred streams of media (including text, audio, and video) to be delivered to them automatically.

    Full Text Available Media relations in sport mean maintenance of networks and positive relationships with people in the media to obtain positive media exposure for a sport product (informal and formal information sessions with media representatives. Because of the pervasive influence the media has on marketing success, sport marketers must make concerted efforts to create a positive relationship between their sport event and the media. They may accomplish this by providing the media with press releases, having news conferences, having media-day events (in which the media are invited to interact with the players, coaches, and administrators, providing media guides for the respective sport events and so on. Each of these activities promotes active involvement from the media, which will subsequently contribute to relationship building with the community.

  5. Media multitasking and implicit learning.

    Edwards, Kathleen S; Shin, Myoungju

    2017-07-01

    Media multitasking refers to the simultaneous use of different forms of media. Previous research comparing heavy media multitaskers and light media multitaskers suggests that heavy media multitaskers have a broader scope of attention. The present study explored whether these differences in attentional scope would lead to a greater degree of implicit learning for heavy media multitaskers. The study also examined whether media multitasking behaviour is associated with differences in visual working memory, and whether visual working memory differentially affects the ability to process contextual information. In addition to comparing extreme groups (heavy and light media multitaskers) the study included analysis of people who media multitask in moderation (intermediate media multitaskers). Ninety-four participants were divided into groups based on responses to the media use questionnaire, and completed the contextual cueing and n-back tasks. Results indicated that the speed at which implicit learning occurred was slower in heavy media multitaskers relative to both light and intermediate media multitaskers. There was no relationship between working memory performance and media multitasking group, and no relationship between working memory and implicit learning. There was also no evidence for superior performance of intermediate media multitaskers. A deficit in implicit learning observed in heavy media multitaskers is consistent with previous literature, which suggests that heavy media multitaskers perform more poorly than light media multitaskers in attentional tasks due to their wider attentional scope.

    Full Text Available Few countries in the world have introduced media education into their curriculums. Montenegro became one of them in 2009, when “media literacy” was introduced as an optional subject for 16 and 17 year old students of Gymnasium high schools. This article presents the findings of the first and only research conducted so far on media education in Montenegro. It is a national case study which examines the potential of media education to change the school culture and accelerate education system reform towards embracing the new digital education paradigm in the future. The focus is on the results of research conducted through in-depth interviews with media literacy teachers all over the country. Despite the many challenges, all teachers identify the potential of media education to strengthen some of the key competences of the students and to improve their motivation and academic performance. They also identify potential to change positively school culture by transforming teachers into “cultural mediators” (Morcellini, 2007 and by supporting the formation of a “participative culture” (Jenkins & Kelley, 2013 in schools. This research recommends focusing education reform on spreading the media education pedagogy to the entire curriculum in order to embrace the new digital education paradigm in the future.

  7. Social Media and Bullshit

    Directory of Open Access Journals (Sweden)

    Rasmus Kleis Nielsen

    2015-04-01

    Full Text Available To understand the role of social media in society, we have to understand how social media are understood. We need to analyze how different actors and organizations see and think about technology, the forms of knowledge that people draw on as they make sense of, develop, and use social media. Central among these is bullshit. This short essay discusses bullshit as defined by the philosopher Harry Frankfurt as statements made with little or no concern for their truth-value or justification and argues that social media are accompanied by unusually large amounts of bullshit for two reasons. First, they confront us with epistemological problems and are hard to understand. Second, there is a large demand for knowledge about what they mean, a powerful political economy that generates a lot of statements about social media, including substantial amounts of bullshit. Given the rapid development of social media and their growing importance, this is unlikely to change in the near future. Bullshit is here to stay, and we need to take it seriously intellectually and analytically to understand social media.

    2011-01-01

    Background Mass media exposure has been associated with an increased risk of eating pathology. It is unknown whether indirect media exposure – such as the proliferation of media exposure in an individual’s social network – is also associated with eating disorders. Aims To test hypotheses that both individual (direct) and social network (indirect) mass media exposures were associated with eating pathology in Fiji. Method We assessed several kinds of mass media exposure, media influence, cultural orientation and eating pathology by self-report among adolescent female ethnic Fijians (n = 523). We fitted a series of multiple regression models of eating pathology, assessed by the Eating Disorder Examination Questionnaire (EDE–Q), in which mass media exposures, sociodemographic characteristics and body mass index were entered as predictors. Results Both direct and indirect mass media exposures were associated with eating pathology in unadjusted analyses, whereas in adjusted analyses only social network media exposure was associated with eating pathology. This result was similar when eating pathology was operationalised as either a continuous or a categorical dependent variable (e.g. odds ratio OR = 1.60, 95% CI 1.15–2.23 relating social network media exposure to upper-quartile EDE–Q scores). Subsequent analyses pointed to individual media influence as an important explanatory variable in this association. Conclusions Social network media exposure was associated with eating pathology in this Fijian study sample, independent of direct media exposure and other cultural exposures. Findings warrant further investigation of its health impact in other populations. PMID:21200076

    2016-01-01

    Focusing on stochastic porous media equations, this book places an emphasis on existence theorems, asymptotic behavior and ergodic properties of the associated transition semigroup. Stochastic perturbations of the porous media equation have reviously been considered by physicists, but rigorous mathematical existence results have only recently been found. The porous media equation models a number of different physical phenomena, including the flow of an ideal gas and the diffusion of a compressible fluid through porous media, and also thermal propagation in plasma and plasma radiation. Another important application is to a model of the standard self-organized criticality process, called the "sand-pile model" or the "Bak-Tang-Wiesenfeld model". The book will be of interest to PhD students and researchers in mathematics, physics and biology.

    Full Text Available Review of Lev Manovich, Software Takes Command: Extending the Language of New Media. London: Bloomsbury, 2013, 358 pp. ISBN 978-1-6235-6817-7. In Lev Manovich’s most recent book, this programmatic interrogation of our medial condition leads to the following question: do media still exist after software? This is the question that triggers Manovich’s dialogue both with computing history and with theories of digital media of recent decades, including the extension of his own previous formulations in The Language of New Media, published in 2001, and which became a major reference work in the field. The subtitle of the new book points precisely to this critical revisiting of his earlier work in the context of ubiquitous computing and accelerated transcoding of social, cultural and artistic practices by software.

Increasing the number of outlets (commercial and non-commercial) tends to bring down this bias; but the strongest ef...

    Full Text Available How do the organization and presentation of large-scale social media images recondition the process by which visual knowledge, value, and meaning are made in contemporary conditions? Analyzing fundamental elements in the changing syntax of existing visual software ontology—the ways current social media platforms and aggregators organize and categorize social media images—this article relates how visual materials created within social media platforms manifest distinct modes of knowledge production and acquisition. First, I analyze the structure of social media images within data streams as opposed to previous information organization in a structured database. While the database has no pre-defined notions of time and thus challenges traditional linear forms, the data stream re-emphasizes the linearity of a particular data sequence and activates a set of new relations to contemporary temporalities. Next, I show how these visual arrangements and temporal principles are manifested and discussed in three artworks: “Untitled” (Perfect Lovers by Felix Gonzalez-Torres (1991, The Clock by Christian Marclay (2011, and Last Clock by Jussi Ängeslevä and Ross Cooper (2002. By emphasizing the technical and poetic ways in which social media situate the present as a “thick” historical unit that embodies multiple and synchronous temporalities, this article illuminates some of the conditions, challenges, and tensions between former visual structures and current ones, and unfolds the cultural significations of contemporary big visual data.

    How is science represented by the media? Who defines what counts as a risk, threat or hazard, and why? In what ways do media images of science shape public perceptions? What can cultural and media studies tell us about current scientific controversies? "Media, Risk and Science" is an exciting exploration into an array of important issues, providing a much needed framework for understanding key debates on how the media represent science and risk. In a highly effective way, Stuart Allan weaves together insights from multiple strands of research across diverse disciplines. Among the themes he examines are: the role of science in science fiction, such as "Star Trek"; the problem of 'pseudo-science' in "The X-Files"; and how science is displayed in science museums. Science journalism receives particular attention, with the processes by which science is made 'newsworthy' unravelled for careful scrutiny. The book also includes individual chapters devoted to how the media portray environmental risks, HIV-AIDS, food s...

    Full Text Available The article is devoted to the problem of the survival of the print media in the information market in the conditions of intense competition with online journalism and the whole information flow on the Internet. Despite the predictions of the impending death of print periodicals, more than half of the world adult population read a daily newspaper. At the same time, the trends taking place in the media market, confirm the reduction of print media segment in favor of the Internet. According to TNS-Russia data, only in 2013 the Internet audience has grown by 6 %. At the same time the circulation of print media in the US fell by 15 % in 2008- 2014, in Western Europe – by a quarter. In Russia, subscription circulation periodicals in the second half of 2014 fell by 20.2 %, and on the basis of subscription for the first half of 2015, the national average – 22 % (data of Federal State Unitary Enterprise “Russian Post”. Finding ways to stabilize the fall of the print media, many US publishing houses see the transition from advertcentric business model to consumcentric model.

  7. Children's media policy.

    Science.gov (United States)

    Jordan, Amy B

    2008-01-01

    Amy Jordan addresses the need to balance the media industry's potentially important contributions to the healthy development of America's children against the consequences of excessive and age-inappropriate media exposure. Much of the philosophical tension regarding how much say the government should have about media content and delivery stems from the U.S. Constitution's First Amendment protection against government interference in free speech, including commercial speech. Courts, Jordan says, have repeatedly had to weigh the rights of commercial entities to say what they please against the need to protect vulnerable citizens such as children. This balancing act is complicated even further, she says, because many government regulations apply only to broadcast television and not to non-broadcast media such as the Internet or cable television, though Congress has addressed the need to protect children's privacy online. The need to protect both free speech and children has given rise to a fluid media policy mix of federal mandates and industry self-regulation. Jordan describes the role of the three branches of the federal government in formulating and implementing media policy. She also notes the jockeying for influence in policymaking by industry lobbies, child advocacy groups, and academic researchers. The media industry itself, says Jordan, is spurred to self-regulation when public disapproval grows severe enough to raise the possibility of new government action. Jordan surveys a range of government and industry actions, from legislatively required parental monitoring tools, such as the V-Chip blocking device on television sets, to the voluntary industry ratings systems governing television, movies, and video games, to voluntary social website disclosures to outright government bans, such as indecency and child privacy information collection. She considers the success of these efforts in limiting children's exposure to damaging content and in improving parents

  9. Cosplaying the media mix: Examining Japan's media environment, its static forms, and its influence on cosplay

    Directory of Open Access Journals (Sweden)

    Matthew Ogonoski

    2014-06-01

    Full Text Available Cosplay—costume role-play—has dramatically increased in popularity over the past 20 years in conjunction with the cultural institution of anime, comic book, manga, science fiction, and other related fandom conventions. Cosplay was prominently established in Japan before gaining attention in North America. In this article I analyze the significance of those Japanese origins in relation to the experience of a unique media environment. The aesthetics and practices of cosplay in Japan are fundamentally informed by a specific ontological characteristic of Japanese anime, manga, and ancillary forms: the static image. Of essential importance to these consumption practices—both materially and conceptually—is the phenomenon of the anime database: an archive of static images that is continually accessed for the purposes of understanding, consuming, and creating new media. Through a detailed discussion of Hiroki Azuma's conception of the moe database, Thomas Lamarre's discussion of the cel bank as a material requisite of the database, and Marc Steinberg's assessment of the media mix, I extend the phenomenological affects of this media environment and its static images to the act of cosplay posing—an act that aspires to create a mimetic and collective connection between cosplayers and particular media images. This exploratory platform will permit me to develop specific conceptions of Japan's complex media environment and its transformations of material forms into ephemeral consumption practices.

  10. [Influence of the news media].

    1991-01-01

    Newspapers, in addition to news, also cover topics of permanent interest to their readers. One such topic is sexuality. The appearance of the incurable sexually transmitted disease AIDS obliges a reconsideration of the complex and contradictory concept of sexuality. Sexuality is not often spoken of openly; rather, it is secret, hidden, and referred to obliquely. Sexuality is the manifestation and satisfaction of the sexual impulses common to all individuals. Sexuality is determined by anatomic and physiologic aspects and also by the knowledge, experiences, values, and norms internalized by the individual living in a social group. Messages about sexual conduct are constantly being received. This social part of sexuality supported by customs and morals is the part that is directly influenced by communications media. An important objective of the media is to create awareness and mold opinions. Mexico's large national circulation newspapers present different points of view about sexuality. Newspapers that continually critique homosexual practices and those that demonstrate implicit approval of pornographic videos by advertising them both present attitudes without providing opportunities to reason, compare, or support opinions. Sexuality is usually referred to indirectly and superficially in the press. Sex education may be mentioned but not the erotic implications of sexuality, and acceptance or opposition to use of condoms may be discussed without mention of psychological barriers to their use. The national press is not prepared to propose new attitudes toward sexuality in the age of AIDS. Only 1 national newspaper in Mexico regularly provides information on AIDS including aspects related to sexual pleasure and responsibility and safer sex. The majority continue with their pre-AIDS coverage of sexuality, using it to arouse interest but providing little depth. Newspapers should provide more extensive coverage on sexuality and its modifications due to AIDS, a reality

  11. Doing social media analytics

    Directory of Open Access Journals (Sweden)

    Phillip Brooker

    2016-07-01

    Full Text Available In the few years since the advent of ‘Big Data’ research, social media analytics has begun to accumulate studies drawing on social media as a resource and tool for research work. Yet, there has been relatively little attention paid to the development of methodologies for handling this kind of data. The few works that exist in this area often reflect upon the implications of ‘grand’ social science methodological concepts for new social media research (i.e. they focus on general issues such as sampling, data validity, ethics, etc.. By contrast, we advance an abductively oriented methodological suite designed to explore the construction of phenomena played out through social media. To do this, we use a software tool – Chorus – to illustrate a visual analytic approach to data. Informed by visual analytic principles, we posit a two-by-two methodological model of social media analytics, combining two data collection strategies with two analytic modes. We go on to demonstrate each of these four approaches ‘in action’, to help clarify how and why they might be used to address various research questions.

  12. Contemplative Media Studies

    Directory of Open Access Journals (Sweden)

    Kevin Healey

    2015-08-01

    Full Text Available The psychological and socio-economic implications of digital technologies call for scholarship that engages questions about the nature of human consciousness, the construction of the self and the ethics of technical development. In this article, I outline a framework for an approach called contemplative media studies. This approach incorporates several different scholarly threads, namely: via critical political-economic media scholarship, a focus on achieving social and economic justice through policy initiatives and structural reform; via media and religious scholarship, an interest in the religious dimensions of digital culture and the role of media in shaping religious identity; and via contemplative studies, an appreciation of the applicability of contemplative principles to research methods and theory. This framework allows us to examine the spiritual ideology that drives the construction of commercial digital platforms and to ask whether alternative platforms might better catalyze human development. Anchored in a critical commitment to socio-economic justice, contemplative media studies is aimed at articulating an ethically-responsive and economically-sustainable architecture of human flourishing.

    From 'Save the Hubble' campaign to ESA's Rosetta mission, social media has played a major role in public engagement and continues to grow. However, with this growing number of social media platforms and the amount of content that goes public daily, the 'noise' level is high - making it difficult to reach a good, relevant audience. Hence, it's important to use different strategies with the content created, from launching a video to live session to issue a press release. Under the Horizon 2020, the Europlanet Media Centre[1] identifies the importance of using social media for outreach. Europlanet uses primary and secondary social media platforms strategically to engage with the followers and a new audience.

    Leveridge, Michael J

    2014-01-01

    Social media have become so integrated into modern communications as to be universal in our personal and, increasingly, professional lives. Recent examples of social media uptake in urology, and the emergence of data to quantify it, reveal the expansion of conventional communication routes beyond the in-person forum. In every domain of urologic practice, from patient interaction through research to continuing professional development, the move online has unlocked another layer of conversation, dissemination, and, indeed, caveats. Social media have a democratizing effect, placing patients, trainees, practitioners, and thought leaders in the same arena and on equal footing. If uptake of social media in medicine even remotely parallels its rise to ubiquity in other areas, it will only expand and evolve in the coming years. For these reasons, this article presents an overview of the most recent data on the impact and potential complications of social media usage in the urologic community.

  15. News Media Consumption and Political Behavior in Latin America

    Directory of Open Access Journals (Sweden)

    Ryan Salzman

    2015-01-01

    Full Text Available News media are an important factor in any democratic society. Research focused on developed democracies has paved the way for analysis in the context of less well-developed democracies. The project endeavors to continue that investigation into whether and how news media consumption affects democratic behavior among individuals in a region comprised of developing democracies: Latin America. Employing rich survey data available from the 2008 Latin American Public Opinion Project, traditional analyses are used to test one of the most basic questions for political communication researchers: Does news media consumption motivate or depress political participation? The results indicate that, on average, news media mobilize political participation, albeit to different degrees per medium and participation type. This seems to happen because those media socialize Latin Americans to value political participation.

    Decades of research have shown that violent media exposure is one risk factor for aggression. This review presents findings from recent cross-sectional, experimental, and longitudinal studies, demonstrating the triangulation of evidence within the field. Importantly, this review also illustrates how media violence research has started to move away from merely establishing the existence of media effects and instead has begun to investigate the mechanisms underlying these effects and their limitations. Such studies range from investigations into cross-cultural differences to neurophysiological effects, and the interplay between media, individual, and contextual factors. Although violent media effects have been well-established for some time, they are not monolithic, and recent findings continue to shed light on the nuances and complexities of such effects.

    As the organ shortage continues to grow, the creation of social media communities by transplant hospitals and the public is rapidly expanding to increase the number of living donors. Social media communities are arranged in myriad ways and without standardization, raising concerns about transplant candidates' and potential donors' autonomy and quality of care. Social media communities magnify and modify extant ethical issues in deceased and living donation related to privacy, confidentiality, professionalism, and informed consent, and increase the potential for undue influence and coercion for potential donors and transplant candidates. Currently, no national ethical guidelines have been developed in the United States regarding the use of social media to foster organ transplantation. We provide an ethical framework to guide transplant stakeholders in using social media for public and patient communication about transplantation and living donation, and offer recommendations for transplant clinical practice and future research. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  19. Liveness redux: on media and their claim to be live.

    2017-11-01

    Increasingly media are asserting themselves as live. In television, this has been an important strategy and recently it has been employed by new media platforms such as Facebook, Periscope and Snapchat. This commentary explains the revival of live media by exploring the meaning and operations of the concept and argues the continued relevance of the concept for the study of social media. Traditionally, there have been three main approaches to the live in academic writing (i.e. liveness as ontology, as phenomenology and as rhetoric): each has its particular shortcoming. This paper proposes that it is more productive to understand the live as a construction that assists to secure media a central role in everyday life.

    2010-03-01

    Full Text Available One of the distinctive marks of current capitalism is the presence of mass media constituting the psyche in different aspects. Today, we observe the multiplication of many contents with erotic appeal in the media and the effects of this process are still to be known, particularly in the matter of sexuality. Concretely, what we have is that the practices and the effective conceptions of sexuality are suffering an accelerated transformation that involves the abandonment of the traditional practices. In this context, we can ask about the sense that is attributed to sexuality experiences and evaluate the impact of the different "manners of being" which are referred to sexuality and systematically diffused by the media. Therefore, we can explore the implications of this new scenery for different social realities: the family institution, the affectionate and loving relationships, the school and professional everyday life, as well as the formulation of public politics in this field.

  3. Modern Media Phenomenon

    2011-09-01

    Full Text Available Contemporary media culture is de fi ned by the logic of the victorious spectacle expanding to all areas of life. Post-modern capitalism has turned everyday life and culture into entertainment with the help of the spectacular. In fact, such entertainment results in a fake sense of happiness, pop mainstream, the swallowing up alternatives and therefore the creation of a passive consumer society. The media today have a unique power of overwhelming a person with information. They enable a modern person to know much, but understand little. This discussion has cast some light on very popular reality shows, the body and sports. It concludes with a re fl ection on modern media, which leave a person of this age with a patchwork identity.

  9. Death in media

    Directory of Open Access Journals (Sweden)

    Pavićević Aleksandra

    2010-01-01

    Full Text Available This paper discusses the role of media in a construction of public image speech and presentation of death. The main research questions could be posed as follows: does the media discourse confirm a thesis about modern society as the one which intensely avoids encounter with Death, or does it defy it? Frequent images or hints of death in visual media in films informative and entertainment programs-suggest certain changes related to this issue in the past few decades. This analysis focuses on printed media hence the paper assesses numerous issues of the daily journal Politika from 1963, 1972, 1973, 1979, 1985, 1991, 1995, 1999, 2007 and 2008, as well as some other daily journals after 2000. The analysis confirms a strong connection between the current political systems and ideology and speech about death. In addition, it reveals a political usage of this event but also speaks up about cultural and historical models, underlying all other constructions. During the 1960's and 1970's, the presentations, including the speech about death relied on the traditional understandings about inevitability of death and dying, and alternatively on atheistic beliefs related to the progress and wellbeing of the society. In this particular discourse, death was present to a limited degree, serving primarily to glorify socialist order. The end of the 1970's witnessed an increase in the glorification of the death, correlated with the decrease of the dominant political ideology. On the other hand, the 1990's brought about more presence of the national and religious symbolism and glorification of the dead as heroes. After 2000, mercantilism is evident throughout the media. All of the media broadcast drastic images of death and dead, thus providing an answer to the posed question at the beginning of this paper about the relationship of the modern society towards death but nevertheless, this still leaves out many implicit consequences and possible meanings.

  10. Catharsis and Media Violence: A Conceptual Analysis

    Directory of Open Access Journals (Sweden)

    Douglas A. Gentile

    2013-12-01

    Full Text Available The concept that doing something to “vent” aggression as a method of reducing aggressive feelings and behaviors, such as watching media violence or playing violent video games, continues to enjoy widespread public support despite a lack of empirical support. This article describes the historical origins of the concept and examines how well these conceptions fit with the modern usage of the aggression catharsis hypothesis. It is argued that there are four primary flaws with the catharsis hypothesis. First, the metaphor underlying Freud, Breuer, and Lorenz’s conception of aggression is flawed. Aggression is not a drive. Second, although Aristotle did use the term catharsis with relation to violent media (plays and poetry, he did not mean that viewing media violence can purge the viewer of aggressive feelings or behaviors. Furthermore, he describes several detailed requirements of plot and character that must be followed if his type of catharsis is to be achieved, and modern media violence does not meet these requirements. Third, the empirical support is not only lacking, a large empirical base contradicts the catharsis hypothesis. This is seen both in studies attempting to demonstrate catharsis directly and in the broader media violence literature. Fourth, human neuroscience contradicts the catharsis hypothesis. Learning is not hindered by viewing something one more time—it is improved. Taken together, it appears that there is no possible way that the aggression catharsis hypothesis can be accurate. It nevertheless continues to “feel” correct at a phenomenological level, and the reasons for this are discussed.

    One in 4 children will have at least 1 episode of acute otitis media (AOM) by age 10 years. AOM results from infection of fluid that has become trapped in the middle ear. The bacteria that most often cause AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Differentiating AOM from otitis media with effusion (OME) is a critical skill for physicians, as accurate diagnosis will guide appropriate treatment of these conditions. Although fluid is present in the middle ear in both conditions, the fluid is not infected in OME as is seen in AOM patients. Copyright © 2014 Elsevier Inc. All rights reserved.

It traces the adoption of new media by religious actors, and analyses the kind of authority these actors have sought to embody, whether regime supporting, oppositional or jihadist....... It argues that the conflict has completely altered the means and modes of Sunni religious communication, transforming classical genres and bypassing them with new ones. It concludes that the lack of formal authority in the messaging of the jihadist groupings, and their failed efforts to build up credible...... religious leaders, is a weakness that could well be exploited in the period to come....

The main function of imitation is memetic which can also build a society as a product of imitation in which it will exist continuously as a social process in almost every society. Therefore, there is a need to build an ethics base, for instance Scheler’s ethics, for the mass media so that it functions to create human character based on love – ordo amoris.

Team SDO continues to be on the forefront of using social media in a very engaging and interactive way and share mission information, solar images and space weather updates via a variety of social media platforms and outlets. We will present the impact SDO's social media strategy has made, including follower, friends and fan statistics from Twitter, Facebook, YouTube, Google+ and other outlets. We will discuss the various social media outlets and the techniques we use for reaching and engaging our audience. Effectiveness is measured through the use of various automatically-gathered statistics and level of public engagement. Of key importance to effective social media use is having access to scientists who can quickly respond to questions and express their answers in meaningful ways to the public. Our presentation will highlight the importance of scientist involvement and suggest ways for encouraging more scientists to support these efforts. We will present some of the social media plans for 2012 and discuss how we can continue to educate, inform, engage and inspire.

  3. Climbing social media in medicine's hierarchy of needs.

    Science.gov (United States)

    Chretien, Katherine C; Kind, Terry

    2014-10-01

    The social media and medicine landscape is evolving rapidly. Early research, social media policies, and educational efforts focused on risk avoidance, while more current efforts have encouraged reflection and explored opportunities. This trajectory has affirmed physicians' professional commitment to maintaining public trust in the face of new challenges in the digital age. In this Commentary, the authors propose viewing physicians' social media use as a hierarchy of needs, similar to Maslow's psychological theory which posits that more basic levels of needs must be met before higher, aspirational levels can be fully attained. The three levels in the social media in medicine's hierarchy of needs are Security, Reflection, and Discovery. Critical to this model is respecting the essential need for Security in order to move towards Reflection and into Discovery. The social media in medicine hierarchy of needs pyramid rests on a foundation of Public Trust. How physicians as a profession have responded to past--and continue to respond to present and future--social media challenges to professionalism reveals what matters most: maintaining public trust and honoring the physicians' contract with society. A victory for online professionalism would be providing trainees with the tools and guidance needed to ascend to Discovery, while ensuring that their basic social media needs are first met. To do this, physician educators need to continue increasing trainees' awareness through designing relevant curricula, encouraging reflection, and providing positive role modeling and effective mentorship.

    Background Social media, including mobile technologies and social networking sites, are being used increasingly as part of human immunodeficiency virus (HIV) prevention and treatment efforts. As an important avenue for communication about HIV, social media use may continue to increase and become more widespread. Objective The objective of this paper is to present a comprehensive systematic review of the current published literature on the design, users, benefits, and limitations of using social media to communicate about HIV prevention and treatment. Methods This review paper used a systematic approach to survey all literature published before February 2014 using 7 electronic databases and a manual search. The inclusion criteria were (1) primary focus on communication/interaction about HIV/acquired immunodeficiency syndrome (AIDS), (2) discusses the use of social media to facilitate communication, (3) communication on the social media platform is between individuals or a group of individuals rather than the use of preset, automated responses from a platform, (4) published before February 19, 2014, and (5) all study designs. Results The search identified 35 original research studies. Thirty studies had low or unclear risk of at least one of the bias items in the methodological quality assessment. Among the 8 social media platform types described, short message service text messaging was most commonly used. Platforms served multiple purposes including disseminating health information, conducting health promotion, sharing experiences, providing social support, and promoting medication adherence. Social media users were diverse in geographic location and race/ethnicity; studies commonly reported users aged 18-40 years and users with lower income. Although most studies did not specify whether use was anonymous, studies reported the importance of anonymity in social media use to communicate about HIV largely due to the stigma associated with HIV.

    All media are social—they are after all media, in between, intermediating between producers and consumers of content, information, conversation, between the actors in the media and the audiences who read, listen, and watch. And the sociality of the media does not stop there: the processes of media production are social processes just as much as the activities of media audiencing. So strictly speaking, all media are social media. But only a particular subset of all media are fundamentally defi...

  19. Femicide in media

    Directory of Open Access Journals (Sweden)

    Mršević Zorica

    2014-01-01

    Full Text Available Media in Serbia explain femicide usually as caused by poverty and alcoholism. This style is gender blind and socially stereotyped because of neglected gender aspects of male violence against women. Particular problem is lack of problematizing obvious social “permission” of male violence. Femicide is regularly presented as an incident, allegedly impossible for anticipation rather than tragic epilogue of long lasting male violence against women which as such exists as a part of traditional gender social relations and roles. Media overlook that alcohol and poverty may only contribute to intensification of already existing, widely accepted domination of men and subordination of women. Media reports as a rule didn’t enter deeper into problems of institutional and social context in which is perpetrated long lasting violence as prefacing femicide. Media also never criticize the social behavior of neighbors, relatives and all others informed on the domestic violence, but rather avoid „mixing“into privacy matters. Thus violence escalates without barriers, eventually developed in femicide, murder a woman, victim of this, decades long lasting violence.

  12. Islam and Media Representations

    Directory of Open Access Journals (Sweden)

    Mohamed Bensalah

    2006-04-01

    Full Text Available For the author of this article, the media’s treatment of Islam has raised numerous polymorphous questions and debates. Reactivated by the great scares of current events, the issue, though an ancient one, calls many things into question. By way of introduction, the author tries to analyse the complex processes of elaboration and perception of the representations that have prevailed during the past century. In referring to the semantic decoding of the abundant colonial literature and iconography, the author strives to translate the extreme xenophobic tensions and the identity crystallisations associated with the current media orchestration of Islam, both in theWest and the East. He then evokes the excesses of the media that are found at the origin of many amalgams wisely maintained between Islam, Islamism and Islamic terrorism, underscoring their duplicity and their willingness to put themselves, consciously, in service to deceivers and directors of awareness, who are very active at the heart of the politico-media sphere. After levelling a severe accusation against the harmful drifts of the media, especially in times of crisis and war, the author concludes by asserting that these tools of communication, once they are freed of their masks and invective apparatuses, can be re-appropriated by new words and bya true communication between peoples and cultures.

    2014-07-01

    Full Text Available From educational gaming through portable e-readers to cell phones, media are interpenetrating educational spaces and activities. Accordingly, understanding media in environmental or ecological terms has become increasingly important for education internationally. In North America, for example, the centenary of McLuhan’s birth has focused attention on approaches to media – whether oral, textual, electronic or digital– as a kind of environment in which education takes place. In parts of Europe, the so-called mediatic turn – following on the linguistic and iconic turns – has similarly emphasized the role of media as a condition for the possibility of educational activities and programs. With a few exceptions1 the papers in this special issue were first presented at the conference «Educational Media Ecologies: International Perspectives» which took place at the University of Paderborn, Germany, on March 27–28, 2012.2 The event was an interdisciplinary and transatlantic endeavor to bring together a wide range of perspectives on various issues relevant to educational media ecologies,3 and on related debates on mediation, medialization, mediatization, and mediality.4 The purpose of this volume, like the conference, is to foster and deepen international dialogue in the area of educational media. Areas of research and scholarship relevant to this dialogue include educational media, media literacy, educational philosophy, and media and cultural studies. The contributions, described below, put conceptual issues as well as social practices and applications at the center of the debate. Klaus Rummler opens the issue by clarifying the concept of ecology itself. Referencing a range of work over the past 50 years, Rummler describes how ecological models have been cast in sociological, semiotic, cultural, mediatic and other terms, and he explains the implications of these various perspectives for the study of educational contexts.

    2017-07-01

    Rydberg blockade physics in optically dense atomic media under the conditions of electromagnetically induced transparency (EIT) leads to strong dissipative interactions between single photons. We introduce a new approach to analyzing this challenging many-body problem in the limit of a large optical depth per blockade radius. In our approach, we separate the single-polariton EIT physics from Rydberg-Rydberg interactions in a serialized manner while using a hard-sphere model for the latter, thus capturing the dualistic particle-wave nature of light as it manifests itself in dissipative Rydberg-EIT media. Using this approach, we analyze the saturation behavior of the transmission through one-dimensional Rydberg-EIT media in the regime of nonperturbative dissipative interactions relevant to current experiments. Our model is able to capture the many-body dynamics of bright, coherent pulses through these strongly interacting media. We compare our model with available experimental data in this regime and find good agreement. We also analyze a scheme for generating regular trains of single photons from continuous-wave input and derive its scaling behavior in the presence of imperfect single-photon EIT.

    2012-08-01

    Full Text Available Abstract Social media includes many different forms of technology including online forums, blogs, microblogs (i.e. Twitter, wikipedias, video blogs, social networks and podcasting. The use of social media has grown exponentially and time spent on social media sites now represents one in five minutes spent online. Concomitant with this online growth, there has been an inverse trajectory in direct face-to-face patient-provider moments, which continue to become scarcer across the spectrum of health care. In contrast to standard forms of engagement and education, social media has advantages to include profound reach, immediate availability, an archived presence and broad accessibility. Our opportunity as health care providers to partner with our patients has never been greater, yet all too often we allow risk averse fears to limit our ability to truly leverage our good content effectively to the online community. This risk averse behavior truly limits our capacity to effectively engage our patients where they are -- online.

This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex.

    Can media pressurize managers to disgorge excess cash to shareholders? Do firms in countries with more independent media follow different dividend policies than firms with less independent media? This paper seeks to answer these questions and aims to document the relationship between media...... for stock market participants. Consequently, stock market participants in emerging markets with more independent media do not demand as high and as much dividends as their counterparts in emerging markets with less independent media. We also show that press independence is more important in defining...... independence and dividend policies in emerging markets. Using a dataset from twenty three emerging markets, we show a significantly negative relationship between dividend policies (payout ratio and decision to pay dividend) and media independence. We argue that independent media reduces information asymmetries...

Therefore, this study used discourse analysis of Theo van Leeuwen focusing on how the subject or actor of the show in the media. This study concluded that the media represent Islam not only with “Western ideology” through idioms such as radical Islamist militants and terrorists, but also with "Islamic ideology". It is done through the construction of Islam as a religion of moderation and delegitimize Charlie Hebdo as magazine satyr abusing freedom. Various strategies are used ranging from strategy passivation to interdetermination. In this case, there are two poles of attraction in both media, namely the Western and Islamic ideology. If both media are quoting from Western sources, the Western ideology dominates the media narrative. Conversely, when both media used Islamic sources, the influence of Islamic ideology dominates the narrative of both media.

  13. Zinc supplements for preventing otitis media.

    Gulani, Anjana; Sachdev, Harshpal S

    2014-06-29

    Otitis media is inflammation of the middle ear and is usually caused by infection. It affects people of all ages but is particularly common in young children. Around 164 million people worldwide have long-term hearing loss caused by this condition, 90% of them in low-income countries. As zinc supplements prevent pneumonia in disadvantaged children, we wanted to investigate whether zinc supplements could also prevent otitis media. To evaluate whether zinc supplements prevent otitis media in adults and children of different ages. We searched CENTRAL (2014, Issue 1), MEDLINE (1950 to February week 4, 2014) and EMBASE (1974 to March 2014). Randomised, placebo-controlled trials of zinc supplements given at least once a week for at least a month for preventing otitis media. Two review authors independently assessed the eligibility and methodological quality of the included trials and extracted and analysed data. We summarised results using risk ratios (RRs) or rate ratios for dichotomous data and mean differences (MDs) for continuous data. We combined trial results where appropriate. No new trials were identified for inclusion in this update. We identified 12 trials for inclusion, 10 of which contributed outcomes data. There were a total of 6820 participants. In trials of healthy children living in low-income communities, two trials did not demonstrate a significant difference between the zinc-supplemented and placebo groups in the numbers of participants experiencing an episode of definite otitis media during follow-up (3191 participants); another trial showed a significantly lower incidence rate of otitis media in the zinc group (rate ratio 0.69, 95% confidence interval (CI) 0.61 to 0.79, n = 1621). A small trial of 39 infants undergoing treatment for severe malnutrition suggested a benefit of zinc for the mean number of episodes of otitis media (mean difference (MD) -1.12 episodes, 95% CI -2.21 to -0.03). Zinc supplements did not seem to cause any serious adverse

    This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. PMID:21186935

    Full Text Available Resource dependence theory and related theories of management suggest online-only news media may displace legacy news media, but until that happens the two systems are likely to be dependent on the same resource: news. This quantitative content analysis finds that the systems exist as parallel but distinctly separate entities. Websites associated with legacy news media such as newspapers publish mostly hard news or news analysis in the form of original work. New, online-only news media publish mostly unoriginal features, but the origins of much of the content published by onlineonly media are unclear.

    2006-01-01

    Full Text Available Young people, the most common consumers of media content, bear out the view that media shapes people’s lives. Therefore we must not underestimate the effect media exerts on young people’s values and behavioral patterns. Television is the medium which draws children and young people for the greatest part of their free time. Regardless whether television programs are described as positive or negative, whether they abound with stereotypes or not, it is important that young people develop a critical attitude towards them so that they may resist different forms of media manipulation. The paper discusses how stereotypes are generated and used by media and the manners in which stereotypical concepts affect young people’s attitudes. It highlights the importance of the development of media literacy which implies a critical attitude towards media images and discourses, the development of criteria for the selection and evaluation of information broadcast by media, the development of skills in interpreting and understanding stereotypical concepts and familiarity with alternative forms of media culture. The paper draws special attention to the issue of media education. The conclusion is that schools should offer media literacy as part of their curriculum and in it possible solutions to the problems discussed. .

Social media presents and changes the communication paradigm in today's society. Communication in social media is not limited by distance, time, and space. It could happen anywhere, anytime, without having a face to face talking. Even social media can negate social status that is often as a barrier in communication. Social media has changed the world. Levels of communication merged into one container called a social media. The rise of many consequences must also be wary of, in the sense of social media opens up the opportunity of each individual involved in it to issue his opinion freely.

Such training is established as an instrument to create research data to “Colaborative Actions to development of production and essay rewriting at elementary school study” that is in progress. Because this is a collaborative research its main goal is to assist the teaching practice in order to make it more consistent and unique with the theoretic and methodologic principles that are ruling our current curricular Portuguese language grade nowadays . Given the limits of this paper, we proposed to analyze the effects of the training as far as the first part of this process: the references given by the teachers to the students to produce the essay and how this proposal was consolidated in the texts produced by the children. To proceed with such study, we are holding on Bakhtin Circle assumptions; Geraldi’s proposals (2006, Magellan studies (2004, Costa-Hübes (2012, and others.

  10. Characterization of pi-conjugated oligopeptide superstructures created via continuous directed self assembly

    Valverde, Lawrence; Schroeder, Charles; Wilson, William

    Development of precise methods for controlling the nanoscale ordering of functional materials is a key challenge to achieving efficient and reliable organic semiconductor-based devices. In this work, we report a new continuous flow method for the directed assembly of oligopeptides with pi-conjugated cores based on tailored flow profile manipulation in microreactors. In particular, we implement 3-D flow focusing of oligopeptide streams combined with a planar extensional flow to achieve supramolecular assembly, alignment, and ordering. We characterize the assembly reaction in real-time using in situ confocal fluorescence microscopy and fluorescence lifetime imaging (FLIM). Through shifts in spectra and fluorescence lifetimes of accompany amyloid formation in oligopeptides with OPV3, 4T, or PDI cores, we demonstrate oligopeptide assembly in a 3D confined volume along the extensional flow axis. Moreover, we characterize assembled materials via the emerging technique of nano-Fourier transform infrared spectroscopy (nano-FTIR), which combines the molecular fingerprinting of traditional FTIR with the spatial resolution of atomic force microscopy (AFM). We further employ conductive probe AFM to characterize the optoelectronic properties of these materials. This work was supported by DOE BES Award #SC-0011847.

    Many knowledges on the mental disease that the community possesses are turning out of information disclosed from the media. It's common in the press to connect actions of violence and murders to the mental diseases. For this reason, the reader is induced to infer that murders and other violent actions are more frequent in people who have suffered from mentally ill, than in the general population. The mystifying impression provided by media accrues from the fact that these reports are rarely compensated from positive reports. Objective of the present study is to characterize the type of information concerning mental illness diffused from the local daily paper "Giornale di Brescia" in the year 2001. The results show that many articles connote negatively the mental disease. The journalistic sensationalism, denounced facing the speech of the prejudgment in the comparisons of the mentally ill people, seems to still remain, in the considered year of publication, one unchanging tendency.

  15. Trust in media information

    Directory of Open Access Journals (Sweden)

    Miquel Rodrigo

    2003-06-01

    Full Text Available For Miquel Rodrigo, cultural diversity places informative discourse in a crisis because it needs new categories to explain reality, and these categories are not always shared by journalists and by those who receive the information. Instead of gaining an easy trust drawnfrom stereotypes, he proposes, as a better way of overcoming the crisis, fostering the existence of sceptical readers. The media interprets social phenomena with its personal and professional limitations. The sceptical reader is one who knows why the media says what it says and understands that its truths are not absolute, since all ways of seeing are ways of concealing. The relationship between scepticism and trust is that which opposes a blind, acrylic and capitulating trust.

This style is gender blind and socially stereotyped because of neglected gender aspects of male violence against women. Particular problem is lack of problematizing obvious social “permission” of male violence. Femicide is regularly presented as an incident, allegedly impossible for anticipation rather than tragic epilogue of long lasting male violence against women which as such ...

  1. Examining the sources of variability in cell culture media used for biopharmaceutical production.

    Science.gov (United States)

    McGillicuddy, Nicola; Floris, Patrick; Albrecht, Simone; Bones, Jonathan

    2018-01-01

    Raw materials, in particular cell culture media, represent a significant source of variability to biopharmaceutical manufacturing processes that can detrimentally affect cellular growth, viability and specific productivity or alter the quality profile of the expressed therapeutic protein. The continual expansion of the biopharmaceutical industry is creating an increasing demand on the production and supply chain consistency for cell culture media, especially as companies embrace intensive continuous processing. Here, we provide a historical perspective regarding the transition from serum containing to serum-free media, the development of chemically-defined cell culture media for biopharmaceutical production using industrial scale bioprocesses and review production mechanisms for liquid and powder culture media. An overview and critique of analytical approaches used for the characterisation of cell culture media and the identification of root causes of variability are also provided, including in-depth liquid phase separations, mass spectrometry and spectroscopic methods.

    2014-01-01

    Social media marketing can be understood as a group of Internet-based applications that build on the foundations of Web 2.0 and that then allows the creation and exchange of ‘User Generated Content’. In the ‘Bowling’ marketing world, marketers target certain customer groups and send out...... this is a very direct one-way communication approach. In a social media marketing world, the bowling metaphor does not fit anymore. On this arena marketing can be better described as playing “Pinball”: Companies serve up a “marketing ball” (brands and brand-building messages) into a dynamic and chaotic market...... environment. The “marketing ball” is then diverted and often accelerated by social media “bumpers”, which change the ball’s course in chaotic ways. Occasionally, the marketing ball will come back to the company.

  3. MEDIA ENTREPRENEURSHIP: A CONSENSUAL DEFINITION

    Directory of Open Access Journals (Sweden)

    DATIS KHAJEHEIAN

    Full Text Available ABSTRACT Media Entrepreneurship has been an ambiguous, unclear and controversial concept and despite of growing academic efforts in the last decade, it is still a poorly defined subject. This paper is an effort to fill this gap by providing a comprehensive definition of media entrepreneurship. Firstly, a literature review conducted and entrepreneurship, media, opportunity and innovation as building blocks of media entrepreneurship explained. Then by using of a mixed of bibliographic method and a Delphi method with multi-stage analysis process, a consensual definition of media entrepreneurship proposed. This definition integrates some key features of the emerging media environment such as distinction of content and platform, value delivery, opportunity development, non-monetary benefit, etc. It is expected that the findings of this research clear the ground for further researches in the field of media entrepreneurship.

  4. Information Provenance in Social Media

    Science.gov (United States)

    Barbier, Geoffrey; Liu, Huan

    Information appearing in social media provides a challenge for determining the provenance of the information. However, the same characteristics that make the social media environment challenging provide unique and untapped opportunities for solving the information provenance problem for social media. Current approaches for tracking provenance information do not scale for social media and consequently there is a gap in provenance methodologies and technologies providing exciting research opportunities for computer scientists and sociologists. This paper introduces a theoretical approach aimed guiding future efforts to realize a provenance capability for social media that is not available today. The guiding vision is the use of social media information itself to realize a useful amount provenance data for information in social media.

  6. Cognitive control in media multitaskers

    Ophir, Eyal; Nass, Clifford; Wagner, Anthony D.

    2009-01-01

    Chronic media multitasking is quickly becoming ubiquitous, although processing multiple incoming streams of information is considered a challenge for human cognition. A series of experiments addressed whether there are systematic differences in information processing styles between chronically heavy and light media multitaskers. A trait media multitasking index was developed to identify groups of heavy and light media multitaskers. These two groups were then compared along established cognitive control dimensions. Results showed that heavy media multitaskers are more susceptible to interference from irrelevant environmental stimuli and from irrelevant representations in memory. This led to the surprising result that heavy media multitaskers performed worse on a test of task-switching ability, likely due to reduced ability to filter out interference from the irrelevant task set. These results demonstrate that media multitasking, a rapidly growing societal trend, is associated with a distinct approach to fundamental information processing. PMID:19706386

  10. Characteristics of Media Audiences and Trust in the media

    Directory of Open Access Journals (Sweden)

    Antonija Čuvalo

    2010-12-01

    Full Text Available This article analyzes elements of the social and demographic profi le of Croatian media audiences in order to identify what may determine their perceptions of the Croatian media and their overall trust in the media. The analytical data that forms the foundation of this examination derives from the research project, “Trust in Media”, ordered by the Faculty of Political Science at the University in Zagreb and conducted in co-operation with the Zagreb-based research agency Media Metar, on nationally representative probability samples. The main assumption is that the diff erences in demographic characteristics and cultural capital within media audiences affect personal attitudes toward media institutions and overall trust in the media. Emphasis is allotted to the differences in professional qualifications, as an indicator of cultural capital, as well as on the diff erences in other social and demographic characteristics and on the relationship of media consumption and trust in media. Relying on the results of previous studies, this article examines the extent of which perception and trust in the media may be explained by differences in social and demographic characteristics.

    2014-09-01

    This review of the literature on disaster media coverage describes the events, samples, and forms of media coverage (television, newspapers, radio, internet) studied and examines the association between media consumption and psychological outcomes. A total of 36 studies representing both man-made and natural events met criteria for review in this analysis. Most studies examined disaster television viewing in the context of terrorism and explored a range of outcomes including posttraumatic stress disorder (PTSD) caseness and posttraumatic stress (PTS), depression, anxiety, stress reactions, and substance use. There is good evidence establishing a relationship between disaster television viewing and various psychological outcomes, especially PTSD caseness and PTS, but studies are too few to draw definitive conclusions about the other forms of media coverage that have been examined. As media technology continues to advance, future research is needed to investigate these additional media forms especially newer forms such as social media.

    Full Text Available Does media exposure to salient criminological events exacerbate racialized perceptions of injustice? We examine whether closely following media coverage of the fatal encounter of George Zimmerman’s shooting of Trayvon Martin moderates racial and ethnic differences in opinion surrounding the event and the U.S. criminal justice system. Our analysis addresses several key aspects of the case: Whether Zimmerman would have been arrested sooner if Martin had been white, whether respondents felt Zimmerman’s acquittal was justified, and whether there is racial bias against African Americans in the criminal justice system. Relying on national opinion surveys before and after Zimmerman’s trial verdict, our findings support the racial gradient thesis by demonstrating that sustained exposure to racialized framing of the incident in the media affects Hispanics the most and hardens entrenched attitudes among African Americans relative to whites. The analysis supports the continuing relevance of the mass media in attitude formation.

    2017-07-01

    Social media's prevalence among the professional world is rapidly increasing. Its use among medical personnel-specifically, medical students, resident physicians, and staff physicians-could compromise personal-professional boundaries. Could the acceptance or lack of acceptance of a friend request bias the medical student application process? If friend requests are accepted, then medical students, resident physicians, and staff physicians are provided access to very personal aspects of one another's lives, which may not have been the intent. The question remains whether the separation of one's personal life from work is necessary. Should medical students restrict social media relationships with residents and staff physicians to professional social media networks? The suitability and opportunities of social media among medical professionals is an ongoing issue for research that needs continued evaluation.

    2015-10-01

    Full Text Available The European Union continuously endeavors to submit to an integrative framework which support the formation of a European spirit and identity. Among the accelerating factors, new media stands for a catalyst of European integration, online networks supporting the users to share opinions, experiences, information, etc. The interactivity provided by new media allow Europeans to learn more about each other and to discover similar or subsidiary objectives. Here, the paper aims to investigate the role of new media in the reconfiguration of social relationships which encompass a shared identity. To this end, several in-depth interviews were conducted with active users who are anchored in online European debates. As the findings showed, new media facilitate people’s engagement in virtual relations and supports the creation of social groups with similar values and standpoints on the European constructs.

    Sigmund, E. E.

    2011-03-01

    Many goals and challenges of research in natural or synthetic porous media are mirrored in quantitative medical MRI. This review will describe examples where MR techniques used in porous media (particularly diffusion-weighted imaging (DWI)) are applied to physiological pathologies. Tissue microstructure is one area with great overlap with porous media science. Diffusion-weighting (esp. in neurological tissue) has motivated models with explicit physical dimensions, statistical parameters, empirical descriptors, or hybrids thereof. Another clinically relevant microscopic process is active flow. Renal (kidney) tissue possesses significant active vascular / tubular transport that manifests as "pseudodiffusion." Cancerous lesions involve anomalies in both structure and flow. The tools of magnetic resonance and their interpretation in porous media has had great impact on clinical MRI, and continued cross-fertilization of ideas can only enhance the progress of both fields.

    Víctor Fco. Sampedro Blanco

    2004-10-01

    Full Text Available The media establish, in large part, the patterns of visibility and public recognition of collective identities. We define media identities as those that are the object of production and diffusion by the media. From this discourse, the communities and individuals elaborate media-influenced identifications; that is, processes of recognition or banishment; (rearticulating the identity markers that the media offer with other cognitive and emotional sources. The generation and appropriation of the identities are subjected to a media hierarchisation that influences their normalisation or marginalisation. The identities presented by the media and assumed by the audience as part of the official, hegemonic discourse are normalised, whereas the identities and identifications formulated in popular and minority terms are marginalised. After presenting this conceptual and analytical framework, this study attempts to outline the logics that condition the presentation, on the one hand, andthe public recognition, on the other hand, of contemporary identities.

  6. Continuous profiling of magnetotelluric fields

    Energy Technology Data Exchange (ETDEWEB)

    Verdin, Carlos Torres [Univ. of California, Berkeley, CA (United States)

    1991-05-01

    The magnetotelluric (MT) method of mapping ground electrical conductivity is traditionally based on measurement of the surface impedance at widely spaced stations to infer models of the subsurface through a suitable pseudo 1-D inverse or with linearized least-squares inversion for 2- or 3-D geoelectric media. It is well known that small near-surface inhomogeneities can produce spatial discontinuities in the measured electric fields over a wide frequency range and may consequently bias the impedance on a very local scale. Inadequate station spacing effectively aliases the electric field measurements and results in distortions that cannot be removed in subsequent processing or modelling. In order to fully exploit the benefits of magnetotellurics in complex geological environments, closely spaced measurements must be used routinely. This thesis entertains an analysis of MT data taken along continuous profiles and is a first step that will allow more encompassing 2-D sampling techniques to become viable in the years to come. The developments presented here are to a large extent motivated by the physical insight gained from low-contrast solutions to the forward MT problem. These solutions describe the relationship between a perturbation in the electrical conductivity of the subsurface and the ensuing perturbation of the MT response as the output of a linear system. Albeit strictly accurate in a limited subset of practical exploration problems, the linearized solutions allow one to pursue a model independent study of the response characteristics of MT data. In fact, these solutions yield simple expressions for 1-,2-, and 3-D resistivity models which are here examined in progressive sequence.

  7. New media and tobacco control.

    Science.gov (United States)

    Freeman, Becky

    2012-03-01

    This paper reviews how the tobacco industry is promoting its products online and examines possible regulation models to limit exposure to this form of marketing. Opportunities to use new media to advance tobacco control are also discussed and future research possibilities are proposed. Published articles and grey literature reports were identified through searches of the electronic databases, PUBMED and Google Scholar using a combination of the following search terms: tobacco or smoking and new media, online media, social media, internet media, Web 2.0, Facebook, YouTube and Twitter. A possible obstacle to fully realising the benefits of regulating tobacco marketing activities and effectively communicating tobacco control messages is the rapid evolution of the media landscape. New media also offer the tobacco industry a powerful and efficient channel for rapidly countering the denormalising strategies and policies of tobacco control. Evidence of tobacco promotion through online media is emerging, with YouTube being the most researched social media site in the tobacco control field. The explosive rise in Internet use and the shift to these new media being driven by consumer generated content through social platforms may mean that fresh approaches to regulating tobacco industry marketing are needed.

    2014-02-01

    Full Text Available By outlining the long-lasting peculiarities of the Greek media landscape, this paper aims to make us reflect on how the political system affects their development and role. Particularly, through analyzing the policy and regulating frames applied to Greek communication field, we try to shed light on the degree and shapes of media concentration and control as well as on the effects of this widespread phenomenon. Special emphasis is placed on the illicit interweaving of political and media interests, giving rise to a media system which has great difficulties in following constructively the technological developments in the field and challenges the active participation of citizens in the public affairs. In the contemporary society of digital revolution market values continue to be dominant. Those who control the private media outweigh the political figures and as a result any attempts to regulate the communication field are always implemented for the benefit of the private capital. Under these circumstances the question of whether the media can act as amplifiers of the democratic practices is more crucial than ever. This is the central question posed by the paper, arguing that the evolution of the Greek media system is inundated with evidence supporting the view that the particular voice of citizen as well as his right to information is under threat.

    The macroscopic properties of fractured porous media locally governed by a Laplace equation are determined by several methods. The first one consists in discretizing the porous medium and the fractures and in solving the Laplace equation in the discretized structure. The other methods consist in successive upscalings. The first upscaling replaces the porous medium by a continuum with a given transport property. The second upscaling replaces the fractures by surfaces with equivalent properties. The results of the various methods give very close results. They suggest a simple approximation which is successful when the properties of the fluid and of the continuous porous medium are not too different.

    A Bayesian consumer who is uncertain about the quality of an information source will infer that the source is of higher quality when its reports conform to the consumer's prior expectations. We use this fact to build a model of media bias in which firms slant their reports toward the prior beliefs of their customers in order to build a reputation for quality. Bias emerges in our model even though it can make all market participants worse off. The model predicts that bias will be less severe w...

    and economically sustainable activity, the institutionalization of financial support for media innovation constitute one way for policy makers to bring (parts of) the journalistic environment up-to-date with the digital age, thereby improving the conditions for an informed citizenry in the future (Kammer......, forthcoming/2016). Theoretically, the paper draws upon the normative foundation of the social-democratic welfare state (found in the Scandinavian countries; cf. Esping-Andersen, 1990) to provide a framework for measuring the ambition, implementation, and impact of the innovation fund. So, this paper...
