Published: February 2017

Hemorrhagic stroke is a devastating disease that lacks effective therapies. In the present investigation, we tested 6-bromoindirubin-3′-oxime (BIO) as a selective glycogen synthase kinase-3β (GSK-3β) inhibitor in a mouse model of intracerebral hemorrhage (ICH). ICH was induced by injection of collagenase IV into the striatum of 8- to 10-week-old C57BL/6 mice. BIO (8 μg/kg, IP) was administered following either an acute delivery (0–2 h delay) or a prolonged regimen (every 48 h starting at 3 days post-ICH). At 2 days post-ICH, the acute BIO treatment significantly reduced the hematoma volume. In the perihematoma regions, BIO administration blocked GSK-3β phosphorylation/activation, increased Bcl-2 and β-catenin levels, and significantly increased viability of neurons and other cell types. The prolonged BIO regimen maintained a higher level of β-catenin, upregulated VEGF and BDNF, and promoted neurogenesis and angiogenesis in peri-injury zones at 14 days after ICH. The BIO treatment also promoted proliferation of neural stem cells (NSCs) and migration of nascent DCX+neuroblasts from the subventricular zone (SVZ) to the lesioned cortex. BIO improved functional outcomes on both the neurological severity score and rotarod tests. The findings of this study corroborate the neuroprotective and regenerative effects of BIO and suggest that the Wnt/GSK-3β/β-catenin pathway may be explored for the treatment of acute or chronic ICH.
Isolation and characterization of microsatellite loci in Sorbus porrigentiformis and cross‐amplification in S. aria and S. rupicola (Rosaceae)
Authors: Piñeiro Rosalía , Karrman‐Bailey Freja , Cowan Robyn S. , Fay Michael F.
Published: February 2017

Premise of the study:

Southwestern Britain is an emblematic hotspot of polyploid diversity of whitebeams (Sorbus aria agg.; Rosaceae) with ca. 30 polyploid endemic species. The tetraploid S. porrigentiformis is postulated as one of the parents of most of these endemics, along with the sexual diploid S. aria s. str. and the tetraploid S. rupicola.

Methods and Results:

We isolated 16 nuclear microsatellite loci from S. porrigentiformis and characterized them on 45 trees representing the three putative parental species. Eleven loci were polymorphic, and eight of them exhibited species‐specific alleles. Allele numbers ranged from one to 11, and observed heterozygosity ranged from 0.40 to 1.00. The intraspecific levels of variation were very low, in agreement with the facultative apomictic reproduction hypothesized for this species.

Conclusions:

The species‐specific alleles will be useful for tracing the origin of the narrowly distributed Sorbus taxa. In addition, the assessment of diversity levels will help design a conservation strategy for the polyploid complex.

This anomalous result challenges both interior models and the dynamical assumptions that enable them, including the essential assumption of apsidal alignment. We also report eclipse depths of 0.081% ± 0.008% in the 3.6 μm channel and 0.088% ± 0.028% in the 4.5 μm channel. These photometric results are non-uniquely consistent with solar-abundance composition without any thermal inversion.
Tracking the Magnetic Flux in and Around Sunspots
Authors: Sheeley Jr. N. R. , Stauffer J. R. , Thomassie J. C. , Warren H. P.
Published: February 2017

We have developed a procedure for tracking sunspots observed by the Helioseismic and Magnetic Imager on the Solar Dynamics Observatory and for making curvature-corrected space/time maps of the associated line-of-sight magnetic field and continuum intensity. We apply this procedure to 36 sunspots, each observed continuously for nine days around its central meridian passage time, and find that the proper motions separate into two distinct components depending on their speeds. Fast (∼3–5 km s−1) motions, comparable to Evershed flows, are produced by weak vertical fluctuations of the horizontal canopy field and recur on a timescale of 12–20 min. Slow (∼0.3–0.5 km s−1) motions diverge from a sunspot-centered ring whose location depends on the size of the sunspot, occurring in the mid-penumbra for large sunspots and at the outer edge of the penumbra for small sunspots. The slow ingoing features are contracting spokes of a quasi-vertical field of umbral polarity. These inflows disappear when the sunspot loses its penumbra, and may be related to inward-moving penumbral grain. The slow outgoing features may have either polarity depending on whether they originate from quasi-vertical fields of umbral polarity or from the outer edge of the canopy. When a sunspot decays, the penumbra and canopy disappear, and the moat becomes filled with slow outflows of umbral polarity. We apply our procedure to decaying sunspots, to long-lived sunspots, and to numerical simulations of a long-lived sunspot by Rempel.
Inferring the Composition of Super-Jupiter Mass Companions of Pulsars with Radio Line Spectroscopy
Authors: Ray Alak , Loeb Abraham
Published: February 2017

We propose using radio line spectroscopy to detect molecular absorption lines (such as OH at 1.6–1.7 GHz) before and after the total eclipse of black widow and other short orbital period binary pulsars with low-mass companions. The companion in such a binary may be ablated away by energetic particles and high-energy radiation produced by the pulsar wind. The observations will probe the eclipsing wind being ablated by the pulsar and constrain the nature of the companion and its surroundings. Maser emission from the interstellar medium stimulated by a pulsar beam might also be detected from the intrabinary medium. The short temporal resolution allowed by the millisecond pulsars can probe this medium with the high angular resolution of the pulsar beam.
Comparing Automatic CME Detections in Multiple LASCO and SECCHI Catalogs
Authors: Hess Phillip , Colaninno Robin C.
Published: February 2017

With the creation of numerous automatic detection algorithms, a number of different catalogs of coronal mass ejections (CMEs) spanning the entirety of the Solar and Heliospheric Observatory (SOHO) Large Angle Spectrometric Coronagraph (LASCO) mission have been created. Some of these catalogs have been further expanded for use on data from the Solar Terrestrial Earth Observatory (STEREO) Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) as well. We compare the results from different automatic detection catalogs (Solar Eruption Event Detection System (SEEDS), Computer Aided CME Tracking (CACTus), and Coronal Image Processing (CORIMP)) to ensure the consistency of detections in each. Over the entire span of the LASCO catalogs, the automatic catalogs are well correlated with one another, to a level greater than 0.88. Focusing on just periods of higher activity, these correlations remain above 0.7. We establish the difficulty in comparing detections over the course of LASCO observations due to the change in the instrument image cadence in 2010. Without adjusting catalogs for the cadence, CME detection rates show a large spike in cycle 24, despite a notable drop in other indices of solar activity. The output from SEEDS, using a consistent image cadence, shows that the CME rate has not significantly changed relative to sunspot number in cycle 24. These data, and mass calculations from CORIMP, lead us to conclude that any apparent increase in CME rate is a result of the change in cadence. We study detection characteristics of CMEs, discussing potential physical changes in events between cycles 23 and 24. We establish that, for detected CMEs, physical parameters can also be sensitive to the cadence.

Radio astronomy has traditionally depended on observatories allocating time to observers for exclusive use of their telescopes. The disadvantage of this scheme is that the data thus collected is rarely used for other astronomy applications, and in many cases, is unsuitable. For example, properly calibrated pulsar search data can, with some reduction, be used for spectral line surveys. A backend that supports plugging in multiple applications to a telescope to perform commensal data analysis will vastly increase the science throughput of the facility. In this paper, we present “SETIBURST,” a robotic, commensal, realtime multi-science backend for the 305 m Arecibo Telescope. The system uses the 1.4 GHz, seven-beam Arecibo L-band Feed Array (ALFA) receiver whenever it is operated. SETIBURST currently supports two applications: SERENDIP VI, a SETI spectrometer that is conducting a search for signs of technological life, and ALFABURST, a fast transient search system that is conducting a survey of fast radio bursts (FRBs). Based on the FRB event rate and the expected usage of ALFA, we expect 0–5 FRB detections over the coming year. SETIBURST also provides the option of plugging in more applications. We outline the motivation for our instrumentation scheme and the scientific motivation of the two surveys, along with their descriptions and related discussions.
Synergies between Asteroseismology and Three-dimensional Simulations of Stellar Turbulence
Authors: Arnett W. David , Moravveji E.
Published: February 2017

Turbulent mixing of chemical elements by convection has fundamental effects on the evolution of stars. The standard algorithm at present, mixing-length theory (MLT), is intrinsically local, and must be supplemented by extensions with adjustable parameters. As a step toward reducing this arbitrariness, we compare asteroseismically inferred internal structures of two Kepler slowly pulsating B stars (SPBs;

) to predictions of 321D turbulence theory, based upon well-resolved, truly turbulent three-dimensional simulations that include boundary physics absent from MLT. We find promising agreement between the steepness and shapes of the theoretically predicted composition profile outside the convective region in 3D simulations and in asteroseismically constrained composition profiles in the best 1D models of the two SPBs. The structure and motion of the boundary layer, and the generation of waves, are discussed.
Selection of Multi-Drug Resistant Influenza A and B Viruses under Zanamivir Pressure and their Replication Fitness in Ferrets
Authors: Oh Ding Yuan , Panozzo Jacqueline , Vitesnik Sophie , Farrukee Rubaiyea , Piedrafita David , Mosse Jennifer , Hurt Aeron C
Published: February 2017

Background

Intravenous zanamivir has been used to treat patients with severe influenza. Because the majority of cases (including immunocompromised patients) require the drug for an extended period of treatment, there is a higher risk that the virus will develop resistance. Therefore, knowing the possible amino acid substitutions that may arise in recently circulating influenza strains under prolonged zanamivir exposure and their impact on antiviral susceptibility is important.

Methods

Influenza A(H1N1)pdm09, A(H3N2) and B virus were serially passaged under increasing zanamivir pressure in vitro. Neuraminidase (NA) mutations that arose were introduced into recombinant viruses and the susceptibility to oseltamivir, zanamivir, peramivir and laninamivir was determined. The replication fitness of the recombinant variants was assessed in the ferret.

Results

NA mutations E119D (N1 numbering) and E117D (B numbering) were detected in A(H1N1)pdm09 and B (Victoria-lineage) viruses respectively and were associated with reduced susceptibility to all four NA inhibitors. No NA mutations were detected in the A(H3N2) or B (Yamagata-lineage) viruses. In ferrets, the A(H1N1) pdm09 E119D variant caused a lower degree of morbidity and the mutation was found to be unstable with E119 reverted virus detected 4 days post-infection of ferrets with the variant E119D virus. In contrast, the influenza B E117D variant was genetically stable in ferrets, caused a noticeable level of morbidity but had a significant reduction in replication fitness compared to wild-type virus.

Conclusions

The NA mutations E119D in influenza A(H1N1)pdm09 and E117D in influenza B viruses that arose under zanamivir pressure conferred resistance to multiple NA inhibitors but had compromised viral replication in ferrets compared to wild-type virus without antiviral drug pressure.
Impact of Tenofovir dose Adjustment on Both Estimated Glomerular Filtration Rate and Tenofovir trough Concentration
Authors: Bregigeon Sylvie , Solas Caroline , Faucher Olivia , Obry-Roguet Véronique , Tamalet Catherine , Poizot-Martin Isabelle
Published: February 2017

Background

Tenofovir disoproxil fumarate (TDF)-based regimen is a treatment option for HIV-infected patients. TDF dose adjustment is recommended in patients with impaired renal function. We assessed the impact of TDF dose adjustment on renal function and tenofovir trough concentration.

Methods

Fourteen HIV patients for whom TDF dose was adjusted (1 tablet/48 h) because of estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2, and/or due to a tenofovir trough concentration >90 ng/ml between 2006 and 2013 were selected. The eGFR was measured at baseline and 3, 6 and 12 months after TDF dose adjustment.

Results

A 50% TDF dose reduction resulted in a significant increase of the eGFR 3 months after dose adjustment (61.1 versus 72.8 ml/min/1.73 m2; P=0.003). Concomitantly, tenofovir trough concentration decreased from 175 to 66 ng/ml ( P=0.009). Antiviral efficacy was maintained in all patients.

Conclusions

TDF dose adjustment combined with therapeutic drug monitoring may be useful especially in patients at risk of kidney dysfunction.
Social labs in universities: Innovation and impact in medialab UGR
Authors: Romero-Frías Esteban , Robinson-García Nicolás
Published: February 2017

Social laboratories, defined as experimental spaces for co-creation, have currently become the main centres of innovation. Medialabs are experimental laboratories of technologies and communication media which have co-evolved along with the digital society into becoming mediation laboratories of citizen experimentation, observing a confluence of both models. In the last years, these centres have expanded within the higher education context, generating new forms of innovation and posing the issue on how to measure the impact of such open spaces. This paper analyzes the origin and development of social laboratories in Spain. It first reviews their historical development since its antecedents in the 19th Century until the most recent initiatives. It focuses specifically on initiatives launched within the university context, highlighting their role as motors of innovation. Then, it presents the case of Medialab UGR, a co-creation and digital culture centre of social collaboration framed in the digital context. Finally, it offers a first approach towards the assessment of its social impact by using the Twitter and analyzes its capacity to mobilize and reach non-academic audiences. The findings show the plurality of actors involved in this type of networks as well as the difficulty and complexity of the task on the development of indicators that can comprise both, academic and social interests.

Los laboratorios sociales, como espacios de experimentación y cocreación, se han convertido en una de las principales instituciones de innovación en nuestros días. En este marco, los medialabs surgen como un tipo de laboratorios centrados en la experimentación con tecnologías y medios de comunicación y evolucionan, con el desarrollo de la sociedad digital, hacia laboratorios de mediación ciudadana e innovación social. En los últimos tiempos se ha producido una expansión de estos modelos en el contexto universitario, generando casos de gran interés para el desarrollo de nuevas métricas del impacto académico en la sociedad. El presente trabajo aborda, en primer lugar, el concepto, origen y desarrollo de los laboratorios sociales en España y globalmente, centrándose específicamente en el espacio universitario y en los medialabs. En segundo lugar, expone la problemática de las métricas alternativas del impacto social, aportando una propuesta de análisis basada en Twitter como herramienta para identificar los distintos tipos de públicos que muestran interés y el nivel de participación que despierta su actividad. Por último, se aplica este análisis al caso de Medialab UGR en la Universidad de Granada, un laboratorio de cultura digital enfocado en la cocreación y colaboración social. Los resultados muestran la pluralidad de actores vinculados a este tipo de redes, así como la dificultad y complejidad de establecer indicadores que concilien tanto intereses académicos como sociales.
Online questionnaires use with automatic feedback for e-innovation in university students

Published: February 2017

Technological tools have permeated higher education programs. However, their mere introduction does not guarantee instructional quality. This article presents the results of an innovation project aimed at fostering autonomous learning among students at a Pre-School and Primary Teacher Grade. For one semester all freshmen students used a system for autonomous learning embedded in the institutional online platform (Moodle), which included automatic formative feedback. The system was part of a complex formative assessment program. We present results of the experience concerning two aspects: the students’ actual use of the system, and their final appraisal of it. The quantitative descriptive analysis focuses on the students’ perspective to evaluate the adequacy of the instructional decisions. Results indicate that students need certain limits to be able to manage their learning better if we pursue the quality of innovation. These limits refer mainly to the time of accessibility and the limitation of attempts of practice. With respect to time, an appropriate span of time (neither too long nor too short) must be chosen; with respect to the number of attempts, it is expedient to limit rather than promote free endless access.

Las herramientas tecnológicas han impregnado plenamente la educación superior. No obstante, el mero añadido no garantiza per se su calidad. Este artículo expone los resultados de un proyecto de innovación para fomentar el aprendizaje autónomo en los Grados de Educación Infantil y Primaria. Durante un semestre todos los alumnos de primer curso pudieron usar un sistema de aprendizaje autónomo en la plataforma online institucional (Moodle), apoyado con feedback formativo automático. El sistema se insertaba en un programa complejo de evaluación formativa. Se presentan resultados atendiendo a dos aspectos: uso real de los estudiantes y valoración final del sistema por parte de estos. El análisis cuantitativo descriptivo se centra en la perspectiva del estudiante para evaluar la adecuación de las decisiones pedagógicas tomadas. Los resultados indican que los estudiantes necesitan ciertos límites para poder organizar mejor su propio aprendizaje si queremos potenciar la calidad de la innovación planteada. Estos límites se concretan en variables tales como el tiempo de disponibilidad y la limitación de intentos de práctica. En el primer caso se debe atender a la duración adecuada de la oferta del sistema: tanto el exceso como el defecto de tiempo afectan a la cantidad y uso que realizan los estudiantes. En el segundo caso, la restricción de intentos es preferible a la práctica libre.
Spanish journalists’ perception about their professional roles
Authors: Berganza Rosa , Lavín Eva , Piñeiro-Naval Valeriano
Published: February 2017

The international empirical research about journalists’ perception of their professional roles and functions presents a remarkable increase in recent years, but not so in the Spanish case. In this research, which is part of the comparative transnational study “Worlds of Journalism Study”, we analyse data from a survey conducted in Spain (representative and stratified by type of media and Autonomous Community) to 390 journalists from 117 media, who were consulted about their work to detect their professional attitudes. The study identifies six roles: the watchdog, the speaker of citizenship, the instructor of the audience, favours the status quo, entertains public opinion and the disseminator of objective information. Professionals feel more identified with the role of speaker of citizenship, in relation with the Spanish political, economic and social changes in recent years. This function downplays the predominant role in the recent similar studies on Spanish journalists: the disseminator of objective information. We also found two large groups of journalists: the stimulators and the narcotizators of public opinion. Moreover, it was observed that some organizational factors (in particular, the property of media) and other individual ones (such as gender, age and years of work experience) significantly influence the perceptions of professional roles.

La investigación empírica internacional sobre la percepción que los periodistas tienen de sus roles y funciones profesionales presenta un notable auge en los últimos años, aunque no en el caso español. Esta investigación, que forma parte del estudio comparativo transnacional «Worlds of Journalism Study», analiza los datos de una encuesta realizada en España (representativa y estratificada por tipo de medio y por Comunidad Autónoma) a 390 periodistas de 117 medios de comunicación, quienes fueron consultados sobre su trabajo para detectar las funciones profesionales con las que más se identificaban. El estudio señala seis roles: el de perro guardián, el altavoz de la ciudadanía, el instructor de la audiencia, el favorecedor del statu quo, el que entretiene a la opinión pública y el difusor de información objetiva. En línea con la evolución política, económica y social de los últimos años en España, los profesionales se identifican más con el papel de altavoz de la ciudadanía. Esta función desplaza en importancia al rol protagonista de los estudios similares más recientes sobre periodistas españoles: el de difusor de la información objetiva. Se hallan también dos grandes grupos de periodistas: los estimuladores y los narcotizadores de la opinión pública. Además, se observa que algunos factores organizacionales (en concreto, la propiedad del medio) y otros individuales (el género, la edad y los años de experiencia laboral) influyen significativamente en las percepciones de los roles profesionales.
Gérer collectivement les tensions organisationnelles du travail : les stratégies d’articulation des logiques de soin et de radioprotection en médecine nucléaire
Authors: Lonceint Romain
Published: February 2017

Le développement de la médecine nucléaire depuis les années 1960 pose la question de l’organisation du travail de soin dans un contexte d’exposition à de faibles doses de radioactivité pour lesquelles les risques demeurent incertains. L’exposition à la radioactivité implique la mise en œuvre de mesures de protection radiologique susceptibles d’entrer en contradiction avec la réalisation du travail de soin. A partir des travaux relatifs aux tensions organisationnelles, cet article interroge les stratégies d’articulation des logiques de soin d’autrui et de protection de soi développées par les professionnels de santé de médecine nucléaire dans leurs pratiques de travail. En nous appuyant sur les résultats d’une étude qualitative conduite dans deux services de médecine nucléaire d’un Centre Hospitalier Universitaire, nous montrons que l’articulation du soin et de la radioprotection s’appuie sur des pratiques de répartition du travail, non seulement entre professionnels de santé mais également à travers la délégation de certaines tâches aux proches des patients ainsi qu’aux patients eux-mêmes. Ces différentes stratégies d’articulation de nature collective, qui visent à gérer une contradiction à travers la mise en compatibilité de deux logiques hétérogènes et divergentes, produisent en retour une hybridation des logiques de soin et de radioprotection.
L’éthique du care , levier de la mobilisation collective des agents hospitaliers. Le cas du pôle gériatrie d’un Centre Hospitalier Régional Universitaire (CHRU)
Authors: Olivaux Marc , Arezki Djelloul , Keramidas Olivier
Published: February 2017

L’hôpital public français, dans le contexte turbulent auquel il fait face, évolue. S’inscrivant dans le paradigme du New Public Management qui vise à introduire des modes de gestion issus de la sphère privée dans le secteur public, les évolutions du cadre juridique transforment l’organisation d’un point de vue structurel en faisant passer l’hôpital d’une logique de moyens à une logique de résultats. Cette quête de performance des organisations publiques peut être facilitée par la mobilisation collective des agents publics. Pour autant le contexte des hôpitaux, dont le fait qu’ils soient des bureaucraties professionnelles, tend à rendre inapplicables les leviers traditionnels des conduites de mobilisation collective. Cette recherche met en évidence l’existence d’un nouveau levier de mobilisation collective potentiel, l’éthique du care . Cette éthique ressort comme intimement reliée aux professions du secteur de la santé. Nous proposons une étude de cas unique portant notamment sur le pôle gériatrique d’un CHRU. Nos résultats, comme le constat que l’éthique du care est en lien avec l’engagement professionnel des agents publics, nous permettent de dégager des recommandations à l’usage des managers afin d’encourager cette mobilisation en favorisant une prise en charge éthique des patients.
Use of Articulating Spacer Technique in Revision Total Knee Arthroplasty Complicated by Sepsis: A Systematic Meta-Analysis
Authors: Spivey John C. , Guild George N. , Scuderi Giles R.
Published: February 2017

Periprosthetic infection after total knee arthroplasty is a devastating complication, and 2-stage exchange is the standard of care in North America. Articulating spacers are effective in treating periprosthetic joint infections, but the optimal articulating spacer construct has yet to be identified. The authors performed a systematic review using MEDLINE, MEDLINE In-Process, EMBASE, BIOSIS,
ClinicalTrials.gov
, and Cochrane Database of Systematic Reviews. They identified 34 articles meeting inclusion criteria, producing 1016 spacers for comparison. Metal-on-polyethylene spacers had a statistically significant increased interim range of motion compared with other spacers (
P
<.003). No statistical differences regarding reinfection rates existed among the 4 types of articulating spacers (
P
<.68). Difficulty of reimplantation was similar between groups (
P
<.10). There were fewer spacer-specific complications with the metal on polyethylene compared with the other groups (
P
<.043) and no spacer fractures. This study answers several clinically relevant questions and provides useful information in guiding clinical decision making in treating periprosthetic infections after total knee arthroplasty. [

Omega Sign: A Distinct Optical Coherence Tomography Finding in Macular Combined Hamartoma of Retina and Retinal Pigment Epithelium
Authors: Kumar Vinod , Chawla Rohan , Tripathy Koushik
Published: February 2017

BACKGROUND AND OBJECTIVE:

To report a distinct optical coherence tomography (OCT) appearance of macular combined hamartoma of retina and retinal pigment epithelium (CHRRPE).

PATIENTS AND METHODS:

This is a retrospective case series of four eyes of four patients with macular CHRRPE who were assessed with the help of color fundus photographs, swept-source OCT (SS-OCT), and fundus fluorescein angiography wherever required.

RESULTS:

All four patients presented with decreased visual acuity. SS-OCT in all patients showed adherent epiretinal membrane (ERM) and localized thickening of underlying retina. An omega-shaped disorganization of inner retinal layers was seen bounded posteriorly by the outer plexiform layer. This was termed, “Omega sign.”

CONCLUSION:

Omega sign is a characteristic feature of macular CHRRPE and may help to distinguish macular CHRRPEs from ERMs.

Building a Music-Mediated Imagined Chinese Community
Authors: Fu Tao , Wang Xingyu
Published: February 2017

This chapter investigates how music acts performed at China Central Television's (CCTV) annual variety show, Chunwan, are used as an ideological package for political communications in China. The authors argue that the Communist Party of China uses songs as the medium for the grand narrative of a shared identity. Chunwan, this televised event, helps construct an imagined community of mainlanders of different social backgrounds, Chinese from Hong Kong, Macao, and Taiwan, and overseas Chinese. Music, disseminated via China's national TV broadcaster, serves as an ideological state apparatus that consolidates the legitimacy of the Party.
Zimbabwe Dancehall Music as a Site of Resistance
Authors: Makwambeni Blessing
Published: February 2017

The popularity and consumption of dancehall music in Zimbabwe has grown exponentially over the past few years. However, despite its popularity, Zimdancehall has attracted controversy for promoting violence and vulgar behavior among other ills. This chapter casts aside society's moral judgements in order to investigate Zimdancehall music's role as an alternative public sphere. Using Fraser's alternative public sphere and Bakhtin's carnivalesque as its conceptual framework, and Norman Fairclough's approach to Critical Discourse Analysis as its methodology, the study analysed the discourses that underpin Zimdancehall music. The chapter argues that Zimdancehall music has become a counter public that provides marginalised youths with a platform to resist the dominant state-sponsored patriotic discourse. The music genre has opened a liberating alternative communicative space, outside of state control and ZANU-PF's patriotic discourse, where marginalised youths can symbolically invert their reality, protest as well as articulate their needs and aspirations freely.
Radio Environment Maps and Its Utility in Resource Management for Dynamic Spectrum Access Networks
Authors: Debroy Saptarshi , Chatterjee Mainak
Published: February 2017

Recent measurements on radio spectrum usage have revealed the abundance of under-utilized bands of spectrum that belong to licensed users. This necessitated the paradigm shift from static to dynamic spectrum access (DSA). Researchers argue that prior knowledge about occupancy of such bands, such as, Radio Environment Maps (REM) can potentially help secondary networks to devise effective strategies to improve utilization. In the chapter, we discuss how different interpolation and statistical techniques are applied to create REMs of a region, i.e., an estimate of primary spectrum usage at any arbitrary location in a secondary DSA network. We demonstrate how such REMs can help in predicting channel performance metrics like channel capacity, spectral efficiency, and secondary network throughput. We show how REMs can help to attain near perfect channel allocation in a centralized secondary network. Finally, we show how the REM can be used to perform multi-channel multi-hop routing in a distributed DSA network.

Mobile operators are showing a growing concern for energy efficiency in cellular networks in the recent past not only to maintain profitability, but also to tackle the overall environment effects. Such a trend is motivating the standardization bodies, network operators and researchers to aggressively explore techniques to reduce the energy consumption in the network. This trend has stimulated the interest of researchers in an innovative new research area called green cellular networks which is a vast research discipline that needs to cover all the layers of the protocol stack and various system architectures. Since Long Term Evolution-Advanced (LTE-A), which promises better support to richer applications, is fast emerging as the next generation cellular network standard and expected to aggravate the energy consumption problem, various techniques have been proposed and researched to improve its energy efficiency. This chapter discusses three link level techniques that attempt to reduce the energy consumption of a LTE-A cell with intelligent MAC layer algorithms.

Authors: Chourasia Sakshi , Sivalingam Krishna Moorthy
Published: February 2017

The mobility management architecture in current generation LTE networks results in high signaling traffic. In this chapter, we present an Evolved Packet Core (EPC) architecture based on Software Defined Networking (SDN) concepts. The proposed EPC architecture centralizes the control plane functionality of the EPC thereby eliminating the use of mobility management protocols and reducing mobility related signaling overheads. The architecture utilizes the global network knowledge with SDN for mobility management. The proposed architecture has been implemented in the ns-3 simulator. A prototype testbed has also been implemented using the Floodlight SDN controller, a Software Defined Radio platform and relevant software.

Published: February 2017

Cloud computing has been a major focus of business organizations around the world. Many applications are getting migrated to the cloud and many new applications are being developed to run on the cloud. There are already more than 100 cloud service providers in the market offering various cloud services. As the number of cloud services and providers is increasing in the market, it is very important to select the right provider and service for deploying an application. This paper focuses on recommendation of cloud services by ranking them with the help of opinion mining of users' reviews and multi-attribute decision making models (TOPSIS and FMADM were applied separately) in tandem on both quantitative and qualitative data. Surprisingly, both TOPSIS and FMADM yielded the same rankings for the cloud services.
Numerical Methods for the Seismic Performance Assessment of Reinforced Concrete Buildings
Authors: Tugsal Ulgen Mert , Taskin Beyza
Published: February 2017

Considering the fact that similar structural and construction deficiencies which are exposed during the recent destructive earthquake events are existing in many southern European, Middle Eastern and west Asian countries settling on highly seismic zones, designating the seismic adequacy of the existing building stock for providing structural safety is a significant necessitation in the mitigation of losses during the future seismic events. In most of these regions, a clear majority of the building stock has not been adequately designed or constructed in terms of the seismic regulations of the design codes, while some have even not benefitted from engineering services. Post-earthquake site observations demonstrate the insufficient capacities in these buildings depending on different structural and construction deficiencies. Within the scope of this research, it is aimed to investigate and compare the analytically calculated structural performances of a building ensemble consists of 3~5 story structures with known damage level by utilizing different procedures.
Evaluation of Walkability and Pedestrian Level of Service
Authors: Tuydes-Yaman Hediye , Karatas Pinar
Published: February 2017

Due to decreasing resources, living in urban regions focus on sustainability in many aspects, including transportation. Sustainable transportation encourages non-motorized modes of walking and cycling as well as public transit (which also relies on walking while accessing a station), as well. However, walking as a mode is still a big mystery itself that needs further attention and research effort especially in the evaluation part. So far, the planners have discussed the concepts of walking and walkability, while engineers have mostly focused on Pedestrian Level of Service (PLOS). The scope of the problem is reflected in the diversity, and consequent inconsistency, in the available PLOS methods, which is one of the problems addressed in this chapter. The second and the bigger problem is the gap between the planning and engineering approaches in evaluating PLOS and walkability producing no consensus or clear relationship between the two, even though they overlap greatly.
