Fostering eGovernment as State Social Responsibility (SSR): Case Study of an Australian City Council
Authors: Karna Sinara Rao , Gupta Divya Kirti 
Published: July 2018

Democracies around the world now face Citizen-apathy. This is a concern now more than ever faced by countries around the globe. eGovernment is undoubtedly a platform to deliberate and enable citizens regain confidence and faith in democratic processes. Citizens now seek Verifiable, Open, Transparent, Empathetic, Responsive and Sensitive Electronic Democracy and Government (VOTERS EDG, Karna, 2012). Similar to corporate world, there are voices stressing on govenments for the need to understand the stakeholders, their involvement, relationships and responsibilities of a state in eGovernance. Citizens everywhere now demand Verifiable, Open, Transparent, Empathetic, Responsive and Sensitive Electronically Democratic Government as a State Social Responsibity (SSR). Peoples movements and outbursts against authorities with the help of Word of Mouse (Karna, 2012) have established that transparent and open governance is the need of the hour. This paper presents findings of the study conducted in an Australian City Council for preparing the city council for ‘City e-readiness’ to initiate e-Government activities. We propose the idea of ‘Centrality of Citizens’ in context of eGovernment. We further build upon the original concept of deeming eGovernment as ‘State Social Responsibility’ (SSR) (Karna, 2010), by governments at all levels.

Published: July 2018

The Matome Saito are edited popular topic threads of the Ni-Channel anonymous bulletin board. The information on the Matome Saito is efficiently and concisely edited for those who do not usually access the vast Ni-Channel forum. This paper overviews the state and mechanism of the Ni-Channel forum of Japan, the edited blogs of Ni-Channel called Matome Saito, and aggregation of Matome Saito in relation to online aggregation and politics, with a focus on Japan and the December 2012 election. This paper examines the tone argument of the Matome Saito aggregation by conducting a content analysis of 148 politically related threads from November 16, 2012 to December 20, 2012 spanning the time period following the dissolving of the Japanese government by Prime Minister Noda to five days after the election.
Linked Information Visualization for Linked Open Government Data. A Visual Synthetics Approach to Governmental Data and Knowledge Collections

Published: July 2018

Open government data initiatives provide citizens with access to the information that governments have about their countries (such as data about people, resources, infrastructure, or services) upon which they act. Information visualizations can help to make sense of these complex data and knowledge collections, but are mostly used to shed light on subselections of data only, without coordinated efforts to connect them to bigger pictures up to now. In analogy to linked data initiatives, this article discusses methods and strategies to link information visualizations in the government data realm and thereby to connect widely available local pictures and insights into more coherent global mental models. We expect related developments to provide benefits for communication professions like civic education and political journalism, and to open up enhanced methods for cross-domain exploration and reasoning for (linked) open government data. Thus linked information visualizations aim for supporting students, readers, and citizens to meet a widening range of macro-cognitive challenges, which complex societies are facing in increasing amounts.
Los caminantes del milagro. Del valle a la ciudad en telediarios locales

Published: July 2018

El trabajo se centra en analizar un conjunto de materiales audiovisuales que testimonian la peregrinación de Cachi, municipio de Salta (Argentina), en el marco de la festividad religiosa del Señor y la Virgen del Milagro. El hecho se constituye en una efeméride y en un caso conmocionante para la mirada mediática de la capital de la provincia. La indagación contrasta un informe periodístico realizado por Canal 11 del año 2012, una nota emitida por Canal 7 del 2016 y un documental del cineasta Alejandro Arroz, El Milagro 1996. El análisis mapea cómo se visibiliza la travesía de los peregrinos que llegan a la ciudad. En dicho trayecto, se inscriben múltiples identidades, territorios y representaciones. Se indaga sobre la manera en la que los medios privilegian ciertas voces eclesiásticas y cómo la mirada popular se filtra en las imágenes y horada el discurso periodístico. Finalmente, se analiza el modo en que los discursos de los peregrinos contaminan el de la información produciendo espacios de vacilación donde lo instituido puede ser interpelado. La metodología es analítica y contrastiva para poder determinar cualitativamente las constantes y las alteraciones a lo largo del tiempo determinando, por una parte, el modo en que se construyen las representaciones y, por otro, el espesor temporal de las mismas.

BackgroundChronic kidney disease (CKD) is diagnosed using the estimated glomerular filtration rate (eGFR) and the urinary albumin:creatinine ratio (ACR). The eGFR is calculated from serum creatinine levels using the Modification of Diet in Renal Disease (MDRD) or Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations.AimTo compare the performance of one versus two eGFR/ACR measurements, and the impact of equation choice, on CKD diagnosis and classification.Design and settingCohort study in primary care in the Thames Valley region of the UK.MethodData were from 485 participants aged >60 years in the Oxford Renal Cohort Study with at least two eGFR tests. The proportion of study participants diagnosed and classified into different CKD stages using one and two positive tests were compared. Prevalence of CKD diagnosis and classification by CKD stage were compared when eGFR was calculated using MDRD and CKD-EPI equations.ResultsParticipants included in the analysis had a mean age of 72.1 (±6.8) years and 57.0% were female. Use of a single screening test overestimated the proportion of people with CKD by around 25% no matter which equation was used, compared with the use of two tests. The mean eGFR was 1.4 ml/min/1.73 m2 (95% CI = 1.1 to 1.6) higher using the CKD-EPI equation compared with the MDRD equation. More patients were diagnosed with CKD when using the MDRD equation, compared with the CKD-EPI equation, once (64% versus 63%, respectively) and twice (39% versus 38%, respectively), and 16 individuals, all of who had CKD stages 2 or 3A with MDRD, were reclassified as having a normal urinary ACR when using the CKD-EPI equation.ConclusionCurrent guidance to use two eGFR measures to diagnose CKD remains appropriate in an older primary care population to avoid overdiagnosis. A change from MDRD to CKD-EPI equation could result in one in 12 patients with a CKD diagnosis with MDRD no longer having a diagnosis of CKD.

Abstract
We present high spatial resolution observations of the continuum emission from the young multiple star system UZ Tau at frequencies from 6 to 340 GHz. To quantify the spatial variation of dust emission in the UZ Tau E circumbinary disk, the observed interferometric visibilities are modeled with a simple parametric prescription for the radial surface brightnesses at each frequency. We find evidence that the spectrum steepens with radius in the disk, manifested as a positive correlation between the observing frequency and the radius that encircles a fixed fraction of the emission (R
eff ∝ ν
0.34±0.08). The origins of this size–frequency relation are explored in the context of a theoretical framework for the growth and migration of disk solids. While that framework can reproduce a similar size–frequency relation, it predicts a steeper spectrum than that observed. Moreover, it comes closest to matching the data only on timescales much shorter (≤1 Myr) than the putative UZ Tau age (∼2–3 Myr). These discrepancies are direct consequences of the rapid radial drift rates predicted by models of dust evolution in a smooth gas disk. One way to mitigate that efficiency problem is to invoke small-scale gas pressure modulations that locally concentrate drifting solids. If such particle traps reach high-continuum optical depths at 30–340 GHz with a ∼30%–60% filling fraction in the inner disk (r ≲ 20 au), they can also explain the observed spatial gradient in the UZ Tau E disk spectrum.

Abstract
While interaction with circumstellar material is known to play an important role in Type IIn supernovae (SNe), analyses of the more common SNe IIP and IIL have not traditionally included interaction as a significant power source. However, recent campaigns to observe SNe within days of explosion have revealed narrow emission lines of high-ionization species in the earliest spectra of luminous SNe II of all subclasses. These “flash ionization” features indicate the presence of a confined shell of material around the progenitor star. Here we present the first low-luminosity (LL) SN to show flash ionization features, SN 2016bkv. This SN peaked at M

V
= −16 mag and has Hα expansion velocities under 1350 km s−1 around maximum light, placing it at the faint/slow end of the distribution of SNe IIP (similar to SN 2005cs). The light-curve shape of SN 2016bkv is also extreme among SNe IIP. A very strong initial peak could indicate additional luminosity from circumstellar interaction. A very small fall from the plateau to the nickel tail indicates unusually large production of radioactive nickel compared to other LL SNe IIP. A comparison between nebular spectra of SN 2016bkv and models raises the possibility that SN 2016bkv is an electron-capture supernova.

Abstract
We present the most distant detection of cosmic voids (z ∼ 2.3) and the first detection of three-dimensional voids in the Lyα forest. We used a 3D tomographic map of the absorption with an effective comoving spatial resolution of 2.5 h
−1 Mpc and a volume of 3.15 × 105
h
−3 Mpc3, which was reconstructed from moderate-resolution Keck I/LRIS spectra of 240 background Lyman-break galaxies and quasars in a 0.16 deg2 footprint in the COSMOS field. Voids were detected using a spherical overdensity finder calibrated from hydrodynamical simulations of the intergalactic medium (IGM). This allows us to identify voids in the IGM corresponding to voids in the underlying matter density field, yielding a consistent volume fraction of voids in both data (19.5%) and simulations (18.2%). We fit excursion set models to the void radius function and compare the radially averaged stacked profiles of large voids (r > 5 h
−1 Mpc) to stacked voids in mock observations and the simulated density field. Comparing with 432 coeval galaxies with spectroscopic redshifts in the same volume as the tomographic map, we find that the tomography-identified voids are underdense in galaxies by 5.95σ compared to random cells.

Published: July 2018

Abstract
Motivated by observational searches for subparsec supermassive black hole binaries (SBHBs), we develop a modular analytic model to determine the likelihood for detection of SBHBs by ongoing spectroscopic surveys. The model combines the parameterized rate of orbital evolution of SBHBs in circumbinary disks with the selection effects of spectroscopic surveys and returns a multivariate likelihood for SBHB detection. Based on this model, we find that in order to evolve into the detection window of the spectroscopic searches from larger separations in less than a Hubble time, 108

Accurate Determination of Halo Velocity Bias in Simulations and Its Cosmological Implications

Abstract
A long-standing issue in peculiar velocity cosmology is whether the halo/galaxy velocity bias b

v
= 1 at large scale. The resolution of this important issue must resort to high-precision cosmological simulations. However, this is hampered by another long-standing “sampling artifact” problem in volume-weighted velocity measurement. We circumvent this problem with a hybrid approach. We first measure the statistics free of sampling artifacts, then link them to volume-weighted statistics in theory, and finally solve for the velocity bias. b

v
(determined by our method) is not only free of sampling artifacts but also free of cosmic variance. We apply this method to a ΛCDM N-body simulation of 30723 particles and

box size. For the first time, we determine the halo velocity bias to 0.1%–1% accuracy. Our major findings are as follows: (1)

at

. The deviation from unity (

) increases with k. Depending on halo mass and redshift, it may reach

at

and

at

. The discovered

has a statistically significant impact on the structure growth rate measurement by spectroscopic redshift surveys, including DESI, Euclid, and SKA. (2) Both the sign and the amplitude of b

v
− 1 depend on mass and redshift. These results disagree with the peak model prediction in that b

v
has much weaker deviation from unity, varies with redshift, and can be bigger than unity. (3) Most of the mass and redshift dependences can be compressed into a single dependence on the halo density bias. Based on this finding, we provide an approximate two-parameter fitting formula.
Is It Small-scale, Weak Magnetic Activity That Effectively Heats the Upper Solar Atmosphere?
Authors: Li K. J. , Xu J. C. , Feng W. 
Published: July 2018

Abstract
Solar chromosphere and coronal heating are big questions for astrophysics. Daily measurement of 985 solar spectral irradiances (SSIs) at the spectral intervals 1–39 nm and 116–2416 nm during 2003 March 1 to 2017 October 28 are utilized to investigate phase relation with respect to daily sunspot number, the Mount Wilson sunspot Index, and the Magnetic Plage Strength Index. All the SSIs form in the abnormally heated layer; the upper photosphere, chromosphere, transition region, and corona are found to be significantly more correlated to weak magnetic activity than to strong magnetic activity, and are found to dance in step with weak magnetic activity. All the SSIs that form in the low photosphere, which indicate the “energy” leaked from the solar subsurface, are found to be more related to strong magnetic activity instead and in anti-phase with weak magnetic activity. In the upper photosphere and chromosphere, strong magnetic activity should lead SSI by about a solar rotation, which also implies that weak magnetic activity should take effect from heating there. It is thus small-scale weak magnetic activity that effectively heats the upper solar atmosphere.
A Gap in the Lower Main Sequence Revealed by Gaia Data Release 2

Abstract
We present the discovery of a gap near M

G
≈ 10 in the main sequence on the Hertzsprung–Russell Diagram (HRD) based on measurements presented in Gaia Data Release 2 (DR2). Using an observational form of the HRD with M

G
representing luminosity and G
BP − G
RP representing temperature, the gap presents a diagonal feature that dips toward lower luminosities at redder colors. The gap is seen in samples extracted from DR2 with various distances, and is not unique to the Gaia photometry—it also appears when using near-IR (NIR) photometry (J − K

s
versus

). The gap is very narrow (∼0.05 mag) and is near the luminosity–temperature regime where M dwarf stars transition from partially to fully convective, i.e., near spectral type M3.0V. This gap provides a new feature in the HRD that hints at an underlying astrophysical cause, and we propose that it is linked to the onset of full convection in M dwarfs.
