Participatory Journalism and Crisis Communications: A Swedish Case Study of Swine Flu Coverage

Public relations research has recently explored how the digitalization of the media has affected crisis communications, focusing on such phenomena as corporate websites and blogs. This study first argues that digitalization involving user participation also changes traditional news production and that this affects the frame in which issues and crisis are told and understood. It then empirically explores media users’ influence on news frameworks through a case study of how mainstream Swedish online news covered the swine flu outbreak in 2009, finding that such users were an integral part of the media coverage of that crisis, contributing with a variety of voices that primarily criticized the media’s paradigms. It concludes by discussing these findings’ implications for crisis communications, in particular the impact of crisis communications becoming multidirectional and decentralized through participatory journalism.
Ozone Monitoring Instrument spectral UV irradiance products: comparison with ground based measurements at an urban environment

Abstract. We have compared spectral ultraviolet overpass irradiances from the Ozone Monitoring Instruments (OMI) against ground-based Brewer measurements at Thessaloniki, Greece from September 2004 to December 2007. It is demonstrated that OMI overestimates UV irradiances by 30%, 17% and 13% for 305 nm, 324 nm, and 380 nm respectively and 20% for erythemally weighted irradiance. The bias between OMI and Brewer increases with increasing aerosol absorption optical thickness. We present methodologies that can be applied for correcting this bias based on experimental results derived from the comparison period and also theoretical approaches using radiative transfer model calculations. All correction approaches minimize the bias and the standard deviation of the ratio OMI versus Brewer ratio. According to the results, the best correction approach suggests that the OMI UV product has to be multiplied by a correction factor CA(λ) of the order of 0.8, 0.88 and 0.9 for 305 nm, 324 nm and 380 nm respectively. Limitations and possibilities for applying such methodologies in a global scale are also discussed.
THE REPRESENTATION OF FAMILY IN PRINTED SOAP ADVERTISEMENTS

The issues of communication are not only carried out through spoken or written language, but also through visual and verbal texts. One of the ways of making good advertisements is to relate images of products to everyday life. Advertisements with good images as a representation of product will attract consumers to buy their products. Therefore, in this study entitled The Representation of Family in Printed Soap Advertisements aims to investigate how families are represented in the selected printed soap advertisements visually and verbally. This study also aims to reveal the meaning of the representation in the printed soap advertisements. This study investigates the representation of family in the printed Lifebuoy, Dettol and Nuvo advertisements. This study uses a descriptive qualitative method. The printed soap advertisements are selected by downloading on the internet. The advertisements are taken randomly from www.google. com suitable with each brand name. This study uses order of signification’s theory by Barthes (1957) and reading images’ theory by Kress and Leuween (2006) to analyze the visual elements. The visual elements are divided into two meanings, denotation and connotation. Based on the analyzed data, the study finds that visually families are represented through background, color of clothes, facial expressions, frame size, camera angle, color saturation and the compositions of family members. The results demonstrate that visually families are mostly represented as health, clean, happy and good family. Meanwhile, the verbal elements are investigated by transitivity from Gerot and Wignell (1995). Based on the verbal analysis, families are represented as family who wants to protect their family members.
The mussel pump : properties and modelling

Properties of the blvalve pump were assessed by investigating, in the mussel R4yhlus eduhs, effects on pump characteristics of reduced valve gape , serotonin stlrnulation of cihary activity, as well as spawning. Reduced valve gaping caused a proportional dechne both in flow rate at zero back pressure, V', and in pump pressure at zero flow, AH? , (= AH",,, the coefficient C I Z = L, .Hq2N0 remaining constant. Enhanced beating rate of lateral cilia, induced by serotonin stimulation, did not affect flow rate or pump pressure. Excessive stimulation that eliminated the laterofrontal clrri from the flow pathway had eri-atlc, non-significant effects. Pump pressure and flow rate vaned with the extension of mantle edges and expiratory siphon, as correlated with the valve gape. Retraction of mantle edges and siphon at reduced valve gape results in a reduction in width of the interfilament canals and thus in the distance between opposing bands of lateral cilia. This distance appears to be the main factor in determining pump pressure and flow rate in the mussel and other bivalves The distance tends to be maximal when mantle edges and siphon are fully extended, as they normally are in undisturbed mussels. It is concluded that the rate of water pumping constitutes an emergent property of the spatial geometry of the interfllament canals and the mantle cavlty, rather than a physiologically regulated process. Based partly on the experimental results and kartly on theoretical as_sumptions the pump could be modelled by the equation , ' . P I = , ' .

Prediction of Stock Price Movement Using Continuous Time Models

Predicting stock price movement is generally accepted to be challenging such that until today it is continuously being attempted. This paper attempts to address the problem of stock price movement using continuous time models. Specifically, the paper provides comparative analysis of continuous time models—General Brownian Motion (GBM) and Variance Gamma (VG) in predicting the direction and accurate stock price levels using Monte Carlo methods—Quasi Monte Carlo (QMC) and Least Squares Monte Carlo (LSMC). The hit ratio and mean-absolute percentage error (MAPE) were used to evaluate the models. The empirical tests suggest that either the GBM model or VG model in any Monte Carlo method can be used to predict the direction of stock price movement. In terms of predicting the stock price values, the empirical findings suggest that the GBM model performs well in the QMC method and the VG model performs well in the LSMC method.
HIGH GAIN SLOTTED WAVEGUIDE ANTENNA BASED ON BEAM FOCUSING USING ELECTRICALLY SPLIT RING RESONATOR METASURFACE EMPLOYING NEGATIVE REFRACTIVE INDEX MEDIUM

In this paper, a new high performance slotted waveguide antenna incorporated with negative refractive index metamaterial structure is proposed, designed and experimentally demonstrated. The metamaterial structure is constructed from a multilayer two-directional structure of electrically split ring resonator which exhibits negative refractive index in direction of the radiated wave propagation when it is placed in front of the slotted waveguide antenna. As a result, the radiation beams of the slotted waveguide antenna are focused in both E and H planes, and hence the directivity and the gain are improved, while the beam area is reduced. The proposed antenna and the metamaterial structure operating at 10 GHz are designed, optimized and numerically simulated by using CST software. The effective parameters of the eSRR structure are extracted by Nicolson Ross Weir (NRW) algorithm from the s-parameters. For experimental verification, a proposed antenna operating at 10 GHz is fabricated using both wet etching microwave integrated circuit technique (for the metamaterial structure) and milling technique (for the slotted waveguide antenna). The measurements are carried out in an anechoic chamber. The measured results show that the E plane gain of the proposed slotted waveguide antenna is improved from 6.5 dB to 11 dB as compared to the conventional slotted waveguide antenna. Also, the E plane beamwidth is reduced from 94.1 degrees to about 50 degrees. The antenna return loss and bandwidth are slightly changed. Furthermore, the proposed antenna offered easier fabrication processes with a high gain than the horn antenna, particularly if the proposed antenna is scaled down in dimensionality to work in the THz regime.
Antimicrobial, Antimalarial and Cytoxicity Activities of Constituents of a Bhutanese Variety of Ajania nubigena

Representational Indeterminancy and Enterprise Search: The Importance of Subject Indexes

The proposed research examines the impact that adding context – via the use of subject indexes – to a query has on search results. This design science research is motivated by the need for a solution to the well-documented failure of enterprise search. Preliminary experimental data is presented that indicates that the use of subject indexes to augment full-text search may indeed be a valid solution and thereby encourages continued investigation. Continuing the research, we propose an experiment where we simulate the search for randomly selected (single) documents in a collection. We will use the comparison of search results between full-text only and full-text plus subject metadata searches to evaluate search performance. The primary dependent variable used will be the rank of the searched-for document in the result set returned by the search engine for each search.
Performance Improvement Through Quality Evaluations of Sterile Cactus Moths, Cactoblastis cactorum (Lepidoptera: Pyralidae), Mass-Reared at Two Insectaries

Abstract A bi-national program was established by Mexico and the United States to mitigate the threat of the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae)—an invasive herbivore from South America—to native Opuntia spp. (Caryophyllales: Cactaceae) biodiversity and Opuntia-based industries. Mass-rearing, sterilization, and transport and release technologies assisted with the development of several control tactics including the sterile insect technique. Following the successful eradication of C. cactorum from Mexico and the elimination of C. cactorum from Alabama barrier islands, the bi-national program established an additional mass-rearing insectary for the production of sterile moths. Laboratory and field bioassays were conducted on sterile moths from both insectaries. Bioassays and assessments included moth mass, moth longevity, percentage of female moths mated at time of collection from the insectary, percentage of female moths mated 24 h after collection, flight ability, percentage recaptured after release in the field, and mean distance dispersed from release site. Data from the quality assessments and comparisons between the 2 insectaries were used as feedback mechanisms to make protocol changes in both rearing and handling that improved sterile moth quality and performance.
Using a joint spectral fitting technique to explore the outflow geometry of GX 339-4 during the hard state

Black hole low-mass X-ray binaries (LMXBs) are transient in nature, such that their luminosities and spectra evolve significantly over periods of weeks to months. Such changes are due to physical alterations to the structure of the accretion inflow and gaseous outflows. LMXBs spend most of their time in a hard state (wherein their X-ray spectra are power laws and thus dominated by higher energies), with order-of-magnitude variations in luminosity. A key issue in physically characterising this state is finding a way to dissect the components contributing to this power law emission: this has up to now proved challenging due to degeneracies in spectral modelling. Solving this issue of modelling degeneracy is vital in the broader context of understanding the physics of accretion around black holes, solar mass and supermassive alike---this is a key factor in the fields of active galactic nuclei feedback and supermassive black hole growth. It is also required for the determination of black hole spin via X-ray reflection modelling, since the results of such studies depend on the assumed geometry of the irradiator. In order to disentangle these components, one needs to invoke all the available spectral and timing information, and build a self-consistent physical picture. I will present work we have been doing on attempting to break modelling degeneracies by fitting a semi-analytical outflow-dominated model to broadband observations of GX 339-4 from radio to X-ray, tracking the evolution of key model parameters with the X-ray variability properties of the source. We jointly model the broadband spectra during states of similarity in variability properties, and find key best fit parameters hold indistinguishable values. I will discuss further work we are doing to advance X-ray reflection modelling by adding X-ray emission from the jet to current models.
CYGNSS Launch and Early Ops: Parenting Octuplets

The eight micro-satellite Cyclone Global Navigation Satellite System (CYGNSS) constellation was launched on December 15, 2016. Each of the observatories carries a 4-channel GNSS-R receiver tuned to receive signals reflected by the Earth's ocean surface from which near-surface wind speed is estimated. The mission is focused on providing high temporal and spatial sensing of the wind conditions under and near developing tropical storms and cyclones. CYGNSS is studying the relationship between ocean surface properties, moist atmospheric thermodynamics, radiation and convective dynamics to determine how a cyclone forms, whether it will strengthen, and how much. A recap of launch and early operations is presented via a somewhat humorous analogy to parenting octuplets, with lessons learned included throughout. Topics include the roller-coaster ride of false labor (launch delays); the excitement of the birth, er, launch; the euphoria of seeing all eight μSats born alive and breathing; the adrenaline rush of saving one μSat born on life support; the total exhaustion that comes with round-the clock care and feeding; and the mixed emotions that come with “sending them out into the world” after a few weeks of doting over them to see them grow up and make their mark in the world.
Updating Allport's and Batson's Framework of Religious Orientations: A Reevaluation from the Perspective of Self-Determination Theory and Wulff's Social Cognitive Model

We theoretically and empirically evaluate Allport’s intrinsic-extrinsic and Batson’s quest religious orientations through the lens of self-determination theory (SDT) and Wulff’s social-cognitive model. Confirming our theoretical analysis, we find that Allport’s intrinsic-extrinsic dichotomy fails to correspond empirically to the differentiation between intrinsic and extrinsic motivation within SDT. Whereas Allport’s intrinsic religious orientation was positively related to internalized extrinsic motivation, his two extrinsic (i.e., personal and social) religious orientations were not systematically related to any of the discerned motives within SDT. Furthermore, Batson’s quest orientation was unrelated to any of the SDT concepts but was positively related to symbolic disbelief. The present findings suggest that Allport’s motivational orientations model needs both refinement and relabeling to better fit with recent theoretical evolutions in the field of motivational psychology.

THE SOLAR WIND AND SUPRATHERMAL ION COMPOSITION INVESTIGATION ON THE WIND SPACECRAFT

The Solar Wind and Suprathermal Ion Composition Experiment (SMS) on WIND is designed to determine uniquely the elemental, isotopic, and ionic-charge composition of the solar wind, the temperatures and mean speeds of all major solar-wind ions, from H through Fe, at solar wind speeds ranging from 175 kms -1 (protons) to 1280 kms -1 (Fe+8), and the composition, charge states as well as the 3-dimensional distribution functions of suprathermal ions, including interstellar pick-up He +, of energies up to 230 keV/e. The experiment consists of three instruments with a common Data Processing Unit. Each of the three instruments uses electrostatic analysis followed by a time-of-flight and, as required, an energy measurement. The observations made by SMS will make valuable contributions to the ISTP objectives by providing information regarding the composition and energy distribution of matter entering the magnetosphere. In addition SMS results will have an impact on many areas of solar and heliospheric physics, in particular providing important and unique information on: (i) conditions and processes in the region of the corona where the solar wind is accelerated; (ii) the location of the source regions of the solar wind in the corona; (iii) coronal heating processes; (iv) the extent and causes of variations in the composition of the solar atmosphere; (v) plasma processes in the solar wind; (vi) the acceleration of particles in the solar wind; and (vii) the physics of the pick-up process of interstellar He as well as lunar particles in the solar wind, and the isotopic composition of interstellar helium.
Force feedback linearization for higher-order electromechanical sigma–delta modulators

A higher-order electromechanical sigma–delta modulator can greatly improve the signal-to-noise ratio compared with a second-order loop that only uses the sensing element as a loop filter. However, the electrostatic force feedback on the proof mass is inherently nonlinear, which will produce harmonics in the output spectrum and limits the total signal-to-noise and distortion ratio. High performance inertial sensors, which use sigma–delta modulators as a closed-loop control system, have strict requirements on the output signal distortion. In this paper, nonlinear effects from the force feedback and pick-off circuits are analysed and a strategy for force feedback linearization is put forward which can considerably improve the signal-to-noise and distortion ratio. A PCB prototype of a fifth-order electromechanical modulator with a bulk micromachined accelerometer was used to demonstrate the concept.
ECONOMIC GROWTH AND CORRUPTION IN DEVELOPING ECONOMIES: EVIDENCE FROM LINEAR AND NON-LINEAR PANEL CAUSALITY TESTS

This paper aims at determining the causal relationship between economic growth and corruption in 42 developing countries using linear and non linear panel methods over the period 1998 to 2009. The findings show that the outcome of the causal association depends on the method used. Corruption appears to Granger cause economic growth when the linear panel causality tests are applied and economic growth seems to Granger lead corruption with the nonlinear panel procedures as the modus operandi. The general value of these results is that adequate institutional facilities must be in place in developing economies to reduce losses from corruption, especially within and after periods of economic growth.
Adaptive Initialization Method Based on Spatial Local Information for -Means Algorithm

-means algorithm is a widely used clustering algorithm in data mining and machine learning community. However, the initial guess of cluster centers affects the clustering result seriously, which means that improper initialization cannot lead to a desirous clustering result. How to choose suitable initial centers is an important research issue for -means algorithm. In this paper, we propose an adaptive initialization framework based on spatial local information (AIF-SLI), which takes advantage of local density of data distribution. As it is difficult to estimate density correctly, we develop two approximate estimations: density by -nearest neighborhoods (-NN) and density by -neighborhoods (-Ball), leading to two implements of the proposed framework. Our empirical study on more than 20 datasets shows promising performance of the proposed framework and denotes that it has several advantages: (1) can find the reasonable candidates of initial centers effectively; (2) it can reduce the iterations of -means’ methods significantly; (3) it is robust to outliers; and (4) it is easy to implement.
Some Results on Chromatic Number as a Function of Triangle Count

A variety of powerful extremal results have been shown for the chromatic number of triangle-free graphs. Three noteworthy bounds are in terms of the number of vertices, edges, and maximum degree given by Poljak \& Tuza (1994), and Johansson. There have been comparatively fewer works extending these types of bounds to graphs with a small number of triangles. One noteworthy exception is a result of Alon et. al (1999) bounding the chromatic number for graphs with low degree and few triangles per vertex; this bound is nearly the same as for triangle-free graphs. This type of parametrization is much less rigid, and has appeared in dozens of combinatorial constructions. In this paper, we show a similar type of result for $\chi(G)$ as a function of the number of vertices $n$, the number of edges $m$, as well as the triangle count (both local and global measures). Our results smoothly interpolate between the generic bounds true for all graphs and bounds for triangle-free graphs. Our results are tight for most of these cases; we show how an open problem regarding fractional chromatic number and degeneracy in triangle-free graphs can resolve the small remaining gap in our bounds.
