BUDGETING, BUDGETARY CONTROL AND PERFORMANCE EVALUATION: Evidence from Hospitality Firms in Nigeria
Authors: Egbunike Patrick , Unamma Amaka
Published: January 2018

This study was carried out with the view to address two fundamental issues: first, to determine if there is any association between budget, budgetary control and performance evaluation; second, to ascertain if there is any significant variation in the budget, budgetary control and performance evaluation measures of hospitality firms in Nigeria. The study employed descriptive design and primary data (questionnaire) was the major source of data collection. Questionnaire was administered to a total of six hundred (600) employees of ten (10) selected hospitality firms in Nigeria. The data obtained were analyzed using both descriptive and inferential statistics. Findings indicated that budget and budgetary control could serve as an avenue through which hospitality firms in Nigeria can be evaluated. In addition, it was revealed that there is a significant variation in the budget, budgetary control and performance evaluation of hospitality firms in Nigeria. On the basis of the findings, it was recommended that hospitality firms in Nigeria should carry out performance evaluation on every aspect of their budget and budgetary activities as a way of ensuring that budgeted outcomes are met. Also, budgetary costs should be a basis of choosing the most-fit performance evaluation technique for hospitality firms since such
The Role of Quantitative C-Reactive Protein, White Blood Cell Count and Pyuria in Predicting Urinary Tract Infection among Febrile Infants and Children
Authors: Rimal Hem Sagar , Walavalkar Shripad J
Published: January 2018

Introduction: Urinary tract infection (UTI) is among the commonest bacterial infections in infants and children that warrants early detection and management to prevent long term consequences in kidney causing significant morbidity. The prevalence of UTI varies according to age, gender, race, circumcision status of children but it occurs in 1% of boys and 1 to 3% of girls. There have been studies that have highlighted the importance of C-reactive as an inflammatory marker involved during urinary tract infection in children.Objectives: To find out how Quantitative C-reactive protein level, white blood cell count and pus cells in urine are associated in febrile infants and children with UTI. To find out the antibiotic sensitivity pattern of UTI.Methodology: A prospective cross sectional study was conducted to evaluate febrile infants and children of 2 months to 13 years of age with suspected UTI for a period of six months. Venous blood samples were sent for Quantitative estimation of CRP, White blood cell count and urine samples were sent for urine microscopy and culture sensitivity. Statistical analysis of data was done using SPSS software version 16.Results: Among 210 infants and children enrolled in the study, 62 (29.55%) had positive urine culture, representing 31.2% and 28.6% of female and male populations respectively. The sensitivity, specificity, positive predictive value(PPV) and negative predictive(NPV) value of CRP (with cut off of 1mg/dl) was 77%,81%, 63% & 90% respectively and that of WBC Count (with cut off of > 12000/ml ) were 56%, 88%, 66% & 83% respectively. Similarly for pyuria (with cut off of >10/HPF) using urine culture as gold standard were 63%, 91%,74% and 85% respectively. The most common organism found in urine culture was E. coli 49(79%). Highest number of isolates were sensitive to Nitrofurantoin(96%) and Amikacin(94%) whereas Amoxycillin was resistant to all the organism tested that was the resistance of 100%.The next common antibiotics found to be resistant was cotrimoxazole (70%).Conclusion: Quantitative C- reactive protein and White blood cell count in blood are very useful markers to predict UTI in febrile infants and children. E coli is the commonest pathogen to cause UTI and Pyuria(pus cells > 10/HPF) has high predictive value for UTI. Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 296 - 299
A novel scale for describing visual outcomes in patients following resection of lesions affecting the optic apparatus: the Unified Visual Function Scale
Authors: Makarenko Serge , Ye Vincent , Gooderham Peter A. , Akagami Ryojo
Published: January 2018

OBJECTIVE

Historically, descriptions of visual acuity and visual field change following intracranial procedures have been very rudimentary. Clinicians and researchers have often used basic descriptions, such as “improved,” “worsened,” and “unchanged,” to describe outcomes following resections of tumors affecting the optic apparatus. These descriptors are vague, difficult to quantify, and challenging to apply in a clinical perspective. Several groups have attempted to combine visual acuity and visual fields into a single assessment score, but these are not user-friendly. The authors present a novel way to describe a patient’s visual function as a combination of visual acuity and visual field assessment that is simple to use and can be used by surgeons and researchers to gauge visual outcomes following tumor resection.

METHODS

Visual acuity and visual fields were combined into 3 categories designed around the definitions of legal blindness and fitness to drive in Canada. The authors then applied the scale (the Unified Visual Function Scale, or UVFS) to their previously published case series of perisellar meningiomas to document and test overall visual outcomes for patients undergoing tumor resection. The results were compared with previously documented visual loss scales in the literature.

RESULTS

Using the UVFS the authors were able to capture the overall visual change; the scale was sensitive enough to define the overall visual improvement or worsening quantitatively, using categories that are clinically relevant and understandable.

CONCLUSIONS

The UVFS is a robust way to assess a patient’s vision, combining visual fields and acuity. The implementation of pre- and postoperative assessment is sensitive enough to assess overall change while also providing clinically relevant information for surgeons, and allows for comparisons between treatment groups.
Mechanical thrombectomy in basilar artery occlusion: influence of reperfusion on clinical outcome and impact of the first-line strategy (ADAPT vs stent retriever)
Authors: Gory Benjamin , Mazighi Mikael , Blanc Raphael , Labreuche Julien , Piotin Michel , Turjman Francis , Lapergue Bertrand
Published: January 2018

OBJECTIVE

Several randomized trials have been focused on patients with anterior circulation stroke, whereas few data on posterior circulation stroke are available. Thus, new mechanical thrombectomy (MT) strategies, including a direct-aspiration first-pass technique (ADAPT), remain to be evaluated in basilar artery occlusion (BAO) patients. The authors here assessed the influence of reperfusion on outcome in BAO patients and examined whether ADAPT improves the reperfusion rate compared with stent retriever devices.

METHODS

Three comprehensive stroke centers prospectively collected individual data from BAO patients treated with MT. Baseline characteristics as well as radiographic and clinical outcomes were compared between the 2 MT strategies. The primary outcome measure was the rate of successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) grade of 2b–3. Favorable outcome was defined as a 90-day modified Rankin Scale score of 0–2.

RESULTS

Among the 100 adult patients included in the study, 46 were treated with first-line ADAPT (median age 61 years, IQR 53–71 years; stent-retriever rescue therapy was secondarily used in 12 [26.1%]) and 54 were treated with a primary stent retriever (median age 67 years, IQR 53–78 years). There was no difference in baseline characteristics between the 2 treatment groups, except for the rate of diabetes (19.6% vs 5.7%, respectively, p = 0.035). Successful reperfusion was achieved in 79% of the overall study sample. Overall, the rate of favorable outcome was 36.8% and 90-day all-cause mortality was 44.2%. Successful reperfusion positively impacted favorable outcome (OR 4.57, 95% CI 1.24–16.87, p = 0.023). A nonsignificant trend toward a higher successful reperfusion rate (unadjusted OR 2.56, 95% CI 0.90–7.29, p = 0.071) and a significantly higher rate of complete reperfusion (mTICI grade 3; unadjusted OR 2.59, 95% CI 1.14–5.86, p = 0.021) was found in the ADAPT group. The procedure duration was also significantly lower in the ADAPT group (median 45 minutes, IQR 34 to 62 minutes vs 56 minutes, IQR 40 to 90 minutes; p = 0.05), as was the rate of periprocedural complications (4.3% vs 25.9%, p = 0.003). Symptomatic intracranial hemorrhage (0.0% vs 4.0%, p = 0.51) and 90-day all-cause mortality (46.7% vs 42.0%, p = 0.65) were similar in the 2 groups.

CONCLUSIONS

Among BAO patients, successful reperfusion is a strong predictor of a 90-day favorable outcome, and the choice of ADAPT as the first-line strategy achieves a significantly higher rate of complete reperfusion with a shorter procedure duration.
Investigation of Laser-material Interaction in Case of Aluminium Brazing Process
Authors: Markovits Tamás , Jászberényi András
Published: January 2018

This research work is connected to the applicability of laser source in case of brazing of aluminium materials. Based on our earlier research results it become clear that the brazing flux material is able to improve the laser absorption in case CO2 laser source. A new brazing flux material (Fontargen F 400 MD EVO2) and the CO2 laser interactions were investigated to determine the applicability of laser as a heating source. The application of laser strongly depend on the value of absorption of laser energy into the aluminium base material. From our new result it can be seen that the applied flux can improve the laser absorption, thus the laser heating, but the implementation of brazing process with this flux material brings further challenges.

Rôle de l'érosion différentielle dans la genèse de la dépression calcaire de Tralée (Comté de Kerry, Irlande)
Authors: Saucerotte Michèle
Published: January 2018

The Tralee district, county of Kerry, South-West Ireland, offers an interesting Appalachian style landscape. It probably derives from an old erosion surface which has been dismantled and deformed by tectonic movements until a very recent time (late Tertiary ?) in connection with the Atlantic Ocean opening and the evolution of the Porcupine Seabight.

Under the Mesozoïc and Cenozoïc tropical climates, the Carboniferous limestone was deeply eroded down to a lower level of erosion, between two escarpments built in shales or sandstones. During the Quaternary cold climates, the Namurian shales were much faster eroded and their scarp receded quickly.

Le transroulage face à l'Eurotunnel : perspectives d'avenir pour les ports belges
Authors: Serderidis J.
Published: January 2018

D'un côté ou l'autre de la Manche, et tant pour les ports français que pour ceux appartenant au Northern Range, le spectre de l'Euro¬ tunnel s'apparente de plus en plus à une échéance. Les techniques de manutention horizontale, regroupées sous le vocable de transroulage, voient leurs perspectives de croissance, pourtant en plein boom actuellement, se fermer à moyen terme. L'idée d'une cohabitation entre «un tunnel express performant et des ferries lents et dangereux» paraît de plus en plus aléatoire. Dès lors, les compagnies maritimes concernées, mais aussi les autorités portuaires (soucieuses de placer leurs crédits à bon escient) se posent la question de savoir quel(s) type(s) de liaison maritime pourra(ont) encore subsister. Ou encore : à partir de quel(s) port(s) ces liaisons seront-elles optimalisées ? C'est à ces questions que cette étude, cependant non exhaustive, tente de répondre.

Welke invloed zal de TGV uitoefenen op de regionaal-economische potentiaalwaarden van de zes grote metropolen in West-Europa die met elkaar in verbinding worden gebracht ? De attractie van een metropool voor andere metropolen wordt uitgedrukt in de toege-voegde potentiaalwaarde die bovenop de autonome potentiaalwaar-de wordt gezet. Deze autonome waarde wordt berekend met behulp van een factoranalyse toegepast op een geselécteerd aantal varia-belen ter indicatie van economische kracht. De toegevoegde potentiaalwaarde berust op de relatieve attractiewaarde van een metropool voor de andere metropolen rekening houdend met autonome potentiaalwaarden, gedeeld door de aanvankelijke respectievelijk toekomstige afstand in tijd. De analyse toont dat de grootste metropolen (Zuidoost Engeland en lle-de-France) relatief (niet ab-soluut !) het minste profijt trekken van de TGV tijdswinst, de regio's Nord -Pas-de-Calais en Brabant (Brüssel) zijn de grote winnaars, de Randstad Holland en de regio Keulen nemen een tussenpositie in.

During this period of colonization, of intensive economic development and of birth of the modern Geography, founded by teachers and professors and great manufacturers of the region, it quickly had more than 2 000 members and arrived at 2 268 in the year 1 900. Two objects : make the Geography known, people and their activities in the remote countries and also in the Nord -Pas-de-Calais and neighbouring countries and contribute to the economic development of région du Nord. An important bulletin, an impossing number of conferences, communications, journeys answer to these two objects. At present, with more modest means, with 450 members and close to multiple organisms, the Société continues all these activities with vigour.
Quelques interrogations concernant la politique de rechargement pratiquée sur la flèche de galets des bas-champs de Cayeux (Somme)
Authors: Dolique Franck
Published: January 2018

La politique de défense contre la mer envisagée pour limiter le démaigrissement de la section proximale de la flèche de galets des Bas-Champs de Cayeux repose sur une alimentation initiale accompagnée de rechargements ponctuels pour un volume total de 400 000 m3 sur 5 ans. De nombreuses questions se posent concernant cette politique de gestion. Il n'est pas de notre volonté de remettre en question le principe même de la méthode qui, au vu de ce qui est pratiqué dans le monde, est la meilleure dans le cadre de réductions des réserves sédimentaires utilisables, encore faut-il trouver une ressource de remplacement en quantité suffisante. Les réactions morphodynamiques des rechargements de galets sont encore mal connues. Cet article jette les bases d'une réflexion sur cet aspect en utilisant le cordon des Bas-Champs comme un laboratoire d'expérimentation.
L'eau et les sports nautiques au cœur de la requalification récréative des friches industrialo-minières et des canaux du Nord-Pas-de-Calais
Authors: Scol Jean
Published: January 2018

L'eau est un élément fondamental à toute vie et semble être aussi une composante essentielle du besoin de recréation qui s'exprime en chacun. C'est pourquoi la plupart des grands aménagements de loisir d'extérieur prennent en compte ce facteur et comportent un équipement autorisant les pratiques liées à la présence de l'élément aquatique. Or, le Nord-Pas-de-Calais compte plus de 1 000 hectares de friches industrielles sous forme de terrains inondés et plus de 680 km de voies navigables dont beaucoup sont sous-utilisées en termes de navigation commerciale. Ces espaces 'en eau' se présentent comme une alternative intéressante face à la carence d'espaces naturels favorables à la pratique des loisirs nautiques dans la région et donc comme de formidables opportunités en termes d'aménagements récréatifs ou sportifs.
Les détroits au regard des flux : Zone de transit, zone de carrefour, zone d'intégration ?
Authors: Joan Jean-Marc
Published: January 2018

Les détroits constituent des zones de croisements des flux maritimes et de flux terrestres. Au sein d'une Europe où la mobilité des personnes et des biens est de moins en moins entravée par des barrières administratives et techniques, ces détroits concentrent de plus en plus de flux d'échanges entre les rives qu'ils mettent en relation. Pour autant, les espaces concernés deviennent-ils des territoires intégrés ? Cet article n'a guère la prétention d'apporter des réponses à ce débat mais d'apporter des éléments de réponses et surtout de soulever des pistes de réflexion.
Les risques induits par le recul des falaises meubles sur les côtes nord-bretonnes : difficultés croissantes de la gestion du sentier côtier
Authors: Biville Mathieu , Van Waerbeke Delphine
Published: January 2018

Une des particularités des côtes nord-bretonnes est la présence de falaises taillées dans les matériaux meubles déposés durant le Quaternaire. La vitesse de recul de ces abrupts, déterminée par comparaison cadastrale, avoisine, en moyenne, une dizaine de centimètres par an, mais présente de nombreuses disparités. Aujourd'hui, cette évolution met en danger l'ensemble des aménagements implantés à leur sommet, qu'ils soient agricoles, touristiques ou urbains. A partir d'une enquête menée auprès de chaque commune du littoral nord-breton, nous avons dressé une typologie des aménagements menacés. Le sentier côtier est apparu le plus exposé. Outre la nécessité d'une remise en état constante de ces servitudes de passage, ce sont surtout les risques encourus par les utilisateurs qui préoccupent les municipalités. L'analyse de sites concernés par ce problème a montré l'inadéquation entre la mise en place du sentier littoral et le recul de ces falaises. Il nous est donc apparu primordial de repenser cet aménagement. Une meilleure utilisation des différents aspects juridiques et l'intégration plus globale de la servitude dans l'ensemble des atouts de l'espace littoral nous semblent des compromis adaptés pour limiter les risques liés au recul des falaises meubles et ainsi sécuriser ces cheminements.
Malte : un archipel entre tourisme balnéaire et tourisme culturel au coeur de la méditerranée
Authors: Scol Jean
Published: January 2018

Au cœur de la Méditerranée, l'archipel maltais s'offre aux touristes, surtout européens du nord et du nord-ouest, en destination insulaire subtropicale de proximité. À l'image de nombreuses destinations de la région, Malte attire donc avant tout pour son climat et l'espoir d'y retrouver les joies du tourisme balnéaire. Or les plages y sont plutôt rares et c'est du côté de son patrimoine culturel particulièrement riche et varié et de quelques sites naturels spectaculaires qu'il faut rechercher la matière touristique la plus convaincante. Concernant les flux de visiteurs étrangers, ceux-ci sont dominés par les britanniques. Cependant, si le tourisme de séjour a enregistré une forte croissance jusqu'au milieu des années 1990, celle-ci s'est depuis essoufflée et c'est surtout grâce à la croissance significative du nombre de croisiéristes que Malte continue malgré tout de voir augmenter celui des visiteurs.

La destination, comme d'autres dans l'espace méditerranéen, a semble-t-il atteint son stade de maturité touristique ; une étape du développement que les autorités locales en charge du tourisme tentent de négocier par le passage d'une politique jusqu'alors surtout quantitative à une logique plus qualitative en adéquation avec les objectifs du développement durable.

We present photometric data of the classical nova, V723 Cas (Nova Cas 1995), over a span of 10 years (2006 through 2016) taken with the 0.9 m telescope at Lowell Observatory, operated as the National Undergraduate Research Observatory (NURO) on Anderson Mesa near Flagstaff, Arizona. A photometric analysis of the data produced light curves in the optical bands (Bessel B, V, and R filters). The data analyzed here reveal an asymmetric light curve (steep rise to maximum, followed by a slow decline to minimum), the overall structure of which exhibits pronounced evolution including a decrease in magnitude from year to year, at the rate of ∼0.15 mag yr−1. We model these data with an irradiated secondary and an accretion disk with a hot spot using the eclipsing binary modeling program Nightfall. We find that we can model reasonably well each season of observation by changing very few parameters. The longitude of the hot spot on the disk and the brightness of the irradiated spot on the companion are largely responsible for the majority of the observed changes in the light curve shape and amplitude until 2009. After that, a decrease in the temperature of the white dwarf is required to model the observed light curves. This is supported by Swift/X-Ray Telescope observations, which indicate that nuclear fusion has ceased, and that V723 Cas is no longer detectable in the X-ray.
Evolution of the Solar Lyα Line Profile during the Solar Cycle
Authors: Kowalska-Leszczynska Izabela , Bzowski Maciej , Sokół Justyna M. , Kubiak Marzena A.
Published: January 2018

Recent studies of interstellar neutral (ISN) hydrogen observed by the Interstellar Boundary Explorer (IBEX) suggested that the present understanding of the radiation pressure acting on hydrogen atoms in the heliosphere should be revised. There is a significant discrepancy between theoretical predictions of the ISN H signal using the currently used model of the solar Lyα profile by Tarnopolski & Bzowski and the signal due to ISN H observed by IBEX-Lo. We developed a new model of evolution of the solar Lyα profile that takes into account all available observations of the full-disk solar Lyα profiles from SUMER/SOHO, provided by Lemaire et al., covering practically the entire 23rd solar cycle. The model has three components that reproduce different features of the profile. The main shape of the emission line that is produced in the chromosphere is modeled by the kappa function; the central reversal due to absorption in the transition region is modeled by the Gauss function; and the spectral background is represented by the linear function. The coefficients of all of those components are linear functions of the line-integrated full-disk Lyα irradiance, which is the only free parameter of the model. The new model features potentially important differences in comparison with the model by TB09, which was based on a limited set of observations. This change in the understanding of radiation pressure, especially during low solar activity, may significantly affect the interstellar H and D distributions in the inner heliosphere and their derivative populations.

We investigate the relation between gas and star formation in subgalactic regions, ∼360 pc to ∼1.5 kpc in size, within the nearby starburst dwarf NGC 4449, in order to separate the underlying relation from the effects of sampling at varying spatial scales. Dust and gas mass surface densities are derived by combining new observations at 1.1 mm, obtained with the AzTEC instrument on the Large Millimeter Telescope, with archival infrared images in the range 8–500 μm from the Spitzer Space Telescope and the Herschel Space Observatory. We extend the dynamic range of our millimeter (and dust) maps at the faint end, using a correlation between the far-infrared/millimeter colors F(70)/F(1100) (and F(160)/F(1100)) and the mid-infrared color F(8)/F(24) that we establish for the first time for this and other galaxies. Supplementing our data with maps of the extinction-corrected star formation rate (SFR) surface density, we measure both the SFR–molecular gas and the SFR–total gas relations in NGC 4449. We find that the SFR–molecular gas relation is described by a power law with an exponent that decreases from ∼1.5 to ∼1.2 for increasing region size, while the exponent of the SFR–total gas relation remains constant with a value of ∼1.5 independent of region size. We attribute the molecular law behavior to the increasingly better sampling of the molecular cloud mass function at larger region sizes; conversely, the total gas law behavior likely results from the balance between the atomic and molecular gas phases achieved in regions of active star formation. Our results indicate a nonlinear relation between SFR and gas surface density in NGC 4449, similar to what is observed for galaxy samples.
En chômage ou au chômage : les motifs d’une variation
Authors: Saunier Évelyne
Published: January 2018

L’observation de divers corpus et des articles «  chômage  » des dictionnaires montre un passage progressif de l’usage courant de être/ mettre… en chômage à celui de être /mettre… au chômage , le basculement se produisant à la fin des années 1970. Il s’agit, plus que d’un remplacement, d’une inversion de tendance, l’emploi de en n’ayant pas disparu. Le présent article vise à rendre compte de la variation entre les deux constructions (diachronique, cotextuelle, individuelle…) en termes de construction socialement pertinente du sens. La proposition repose sur une prise en compte de l’évolution de la catégorie « chômage », et sur une analyse sémantique du type de repérage qu’instaurent les deux prépositions entre les termes qu’elles relient.

Abstract. Closing the terrestrial water budget is necessary to provide
consistent estimates of budget components for understanding water resources
and changes over time. Given the lack of in situ observations of budget
components at anything but local scale, merging information from multiple
data sources (e.g., in situ observation, satellite remote sensing, land
surface model, and reanalysis) through data assimilation techniques that
optimize the estimation of fluxes is a promising approach. Conditioned on
the current limited data availability, a systematic method is developed to
optimally combine multiple available data sources for precipitation (P),
evapotranspiration (ET), runoff (R), and the total water storage change
(TWSC) at 0.5∘ spatial resolution globally and to obtain
water budget closure (i.e., to enforce P-ET-R-TWSC= 0) through a constrained
Kalman filter (CKF) data assimilation technique under the assumption that
the deviation from the ensemble mean of all data sources for the same budget
variable is used as a proxy of the uncertainty in individual water budget
variables. The resulting long-term (1984–2010), monthly
0.5∘ resolution global terrestrial water cycle Climate Data
Record (CDR) data set is developed under the auspices of the National
Aeronautics and Space Administration (NASA) Earth System Data Records
(ESDRs) program. This data set serves to bridge the gap between sparsely
gauged regions and the regions with sufficient in situ observations in
investigating the temporal and spatial variability in the terrestrial
hydrology at multiple scales. The CDR created in this study is validated
against in situ measurements like river discharge from the Global Runoff
Data Centre (GRDC) and the United States Geological Survey (USGS), and ET
from FLUXNET. The data set is shown to be reliable and can serve the
scientific community in understanding historical climate variability in
water cycle fluxes and stores, benchmarking the current climate, and
validating models.
Microtopographic control on the ground thermal regime in ice wedge polygons

Published: January 2018

Abstract. The goal of this research is to constrain the influence of ice wedge polygon topography on near-surface ground temperatures. Because ice wedge polygon topography is prone to rapid change in a changing climate, and because cracking in the ice wedge depends on thermal conditions at the top of the permafrost, feedbacks between topography and ground temperature can shed light on the potential for future ice wedge cracking in the Arctic. We first report on a year of subdaily ground temperature observations at five depths and nine locations throughout a cluster of low-centered polygons near Prudhoe Bay, AK, and demonstrate that the rims become the coldest zone of the polygon during winter, due to thinner snowpack. We then calibrate a polygon-scale numerical model of coupled thermal and hydrologic processes against this dataset, achieving an RMSE of less than 1.2 °C between observed and simulated ground temperature. Finally, we conduct a sensitivity analysis of the model by systematically manipulating the height of the rims and the depth of the troughs, and tracking the effects on ice wedge temperature. The results indicate that deeper troughs lead to increased snow entrapment, promoting insulation of the ice wedge. Rims act as preferential outlets of subsurface heat; increasing rim size decreases winter temperatures in the ice wedge. The potential for ice wedge cracking is therefore reduced if rims are destroyed or if troughs subside, due to warmer conditions in the ice wedge. These findings can help explain the origins of secondary ice wedges in modern and ancient polygons. The findings also imply that the potential for reestablishing rims in modern thermokarst-affected terrain will be precluded by reduced cracking activity in the ice wedges, even if regional air temperatures stabilize.
Discrepancies among Scopus, Web of Science, and PubMed coverage of funding information in medical journal articles
Authors: Kokol Peter , Blažun Vošner Helena
Published: January 2018

Objective: The overall aim of the present study was to compare the coverage of existing research funding information for articles indexed in Scopus, Web of Science, and PubMed databases.Methods: The numbers of articles with funding information published in 2015 were identified in the three selected databases and compared using bibliometric analysis of a sample of twenty-eight prestigious medical journals.Results: Frequency analysis of the number of articles with funding information showed statistically significant differences between Scopus, Web of Science, and PubMed databases. The largest proportion of articles with funding information was found in Web of Science (29.0%), followed by PubMed (14.6%) and Scopus (7.7%).Conclusion: The results show that coverage of funding information differs significantly among Scopus, Web of Science, and PubMed databases in a sample of the same medical journals. Moreover, we found that, currently, funding data in PubMed is more difficult to obtain and analyze compared with that in the other two databases. This article has been approved for the Medical Library Association’s Independent Reading Program.

Prensa, opinión y música teatral en Madrid, 1780-1791
Authors: Sánchez-Rojo Ana
Published: January 2018

A través del estudio de dos tonadillas escénicas y de artículos publicados en la prensa periódica madrileña, este trabajo sugiere que el teatro musical en Madrid constituyó un caldo de cultivo para la formación de la opinión pública moderna en España. Este fenómeno se observa de modo particular entre 1780 y 1791, año en que se prohibieron temporalmente las publicaciones periódicas. La reapertura del Teatro de los Caños del Peral en 1787 dio lugar a que los periódicos madrileños publicaran numerosos artículos y cartas debatiendo la posición del teatro extranjero frente al nacional. A raíz de este y otros debates similares, tanto prensa como tonadillas cuestionaron si el fenómeno de la opinión traía algún beneficio a la sociedad española. Como conclusión, se mostrará que la teoría de Jürgen Habermas sobre la esfera pública ilumina algunos aspectos, si bien no todos, de la génesis de la opinión pública en España. Por tanto, el hecho de que el caso español difiera de los considerados por Habermas no quiere decir España haya quedado al margen de los procesos de formación de la opinión pública moderna en Europa.
Un ejemplo de oxímoron en música: el indie en España, una escena comercial
Authors: Barrera-Ramírez Fernando
Published: January 2018

Desde su aparición, la etiqueta indie o independiente se ha convertido en una de las categorías más difíciles de definir dentro de las músicas populares urbanas en España, sobre todo porque en sentido estricto no debería considerarse un género o un estilo musical. Este artículo pretende abordar el estudio de este controvertido término, definirlo, enfrentarlo a los conceptos de género musical y escena, y analizar toda la problemática que rodea a esta etiqueta cambiante, prestando especial atención a muchas de sus contradicciones, siendo la más relevante su particular vinculación con la industria discográfica.
Manifestações imaginológicas distintas na displasia cemento-óssea florida
Authors: De Castro Tamara Fernandes , Iwaki Lilian Cristina Vessoni , Pieralisi Neli , Da Silva Mariliani Chicarelli , Tolentino Elen De Souza
Published: January 2018

A displasia cemento-óssea florida (DCOF) consiste em uma lesão fibro-óssea benigna dos maxilares, onde o osso é substituído por um tecido fibroso semelhante ao cemento. A etiologia desta desordem é desconhecida e apresenta-se totalmente assintomática e, em muitos casos, as lesões são detectadas em uma radiografia tomada para outros fins. Possui maior expressão no gênero feminino, em pacientes melanodermas e de meia idade. Nos exames de imagem, possuem um amplo espectro de apresentações, onde as lesões variam de totalmente radiolúcidas (fase osteolítica), mistas a radiopacas (fase de mineralização). A DCOF pode se assemelhar a lesões como a displasia periapical, cementoma gigantiforme, osteomielite crônica esclerosante difusa e a doença óssea de Paget. O diagnóstico da DCOF é baseado principalmente nos achados clínicos associados aos exames imaginológicos, não havendo a necessidade, na maioria dos casos, de biópsia para o diagnóstico dessa entidade. Na medida do possível procedimentos cirúrgicos devem ser evitados, devido a susceptibilidade do osso a infecções. O objetivo do presente trabalho é relatar dois casos clínicos de pacientes com displasia cemento-óssea florida em diferentes fases, com características distintas no exame de tomografia computadorizada de feixe cônico.
