Is South Korea’s Green Job Policy Sustainable?
Authors: Jung Yeon-Mi
Published: July 2015

South Korea’s green job policy was implemented in February 2008 as a part of low-carbon green growth policy, but has been discontinued at the present. The country’s actual energy and environmental consumption has continuously increased, and South Korean society has grown increasingly distant from sustainable development. The study constructs a theoretical framework centering on sustainable development and analyzes the process and contents of South Korea’s green job policy. We suggest four findings: First, in terms of ideology, the nation’s green job policy was based on green growth. Implemented as a strategy typical of developing countries, South Korea’s green growth was pursued as weak ecological modernization, relatively stressing economic growth and excluding citizens’ participation. Second, in terms of governance, the nation’s green job policy was led by the central government, thus nearly completely destroying existing legal and institutional infrastructures related to sustainable development. Third, South Korea’s green job policy was defined on the basis of a growth orientation and concentrated on the Four Major Rivers Restoration Project and the NPP project, both of which betrayed considerable problems from the perspective of sustainable development. Fourth, green jobs were created in traditional environmental protection and pollution reduction and therefore limited.
Urban Growth and Rural Transition in China Based on DMSP/OLS Nighttime Light Data
Authors: Tan Minghong
Published: July 2015

Nighttime light (NTL) images provide uniform, consistent, and valuable data sources. Based on four reference regions, the NTL imagery of China was fully intercalibrated during the period 1992–2012. Using lit areas and the intensity of NTL imagery, this study synthetically analyzed the urbanization process and rural transition in China. The results showed that, over the whole country, the pixel numbers of urban areas increased by 173% from 1992 to 2012. During the 2000s, urban areas expanded much more quickly than during the 1990s. Urban growth varied greatly across the four regions, which could be pictured using the flying-geese paradigm. In the 1990s, East China experienced the most rapid rate of growth, while a decade later Middle China had the highest growth rate. NTL imagery can also be used to describe changes in rural human activities if the imagery is corrected using completely dark rural pixels. In China, because of the massive rural-urban migration, some marginal regions experienced a decrease in nighttime light intensity (NTLI) and rural areas went through a period of transition.
Genome Characterization, Prevalence and Distribution of a Macula-Like Virus from Apis mellifera and Varroa destructor
Authors: De Miranda Joachim , Cornman R. , Evans Jay , Semberg Emilia , Haddad Nizar , Neumann Peter , Gauthier Laurent
Published: July 2015

Around 14 distinct virus species-complexes have been detected in honeybees, each with one or more strains or sub-species. Here we present the initial characterization of an entirely new virus species-complex discovered in honeybee (Apis mellifera L.) and varroa mite (Varroa destructor) samples from Europe and the USA. The virus has a naturally poly-adenylated RNA genome of about 6500 nucleotides with a genome organization and sequence similar to the Tymoviridae (Tymovirales; Tymoviridae), a predominantly plant-infecting virus family. Literature and laboratory analyses indicated that the virus had not previously been described. The virus is very common in French apiaries, mirroring the results from an extensive Belgian survey, but could not be detected in equally-extensive Swedish and Norwegian bee disease surveys. The virus appears to be closely linked to varroa, with the highest prevalence found in varroa samples and a clear seasonal distribution peaking in autumn, coinciding with the natural varroa population development. Sub-genomic RNA analyses show that bees are definite hosts, while varroa is a possible host and likely vector. The tentative name of Bee Macula-like virus (BeeMLV) is therefore proposed. A second, distantly related Tymoviridae-like virus was also discovered in varroa transcriptomes, tentatively named Varroa Tymo-like virus (VTLV).
L’architecture castrale en Allemagne du XIIIe au début du XVIe siècle
Authors: Biller Thomas , Herrmann Christofer
Published: July 2015

Castle architecture in Germany from the thirteenth to the sixteenth century, by Thomas Biller, Christofer Herrmann

Any attempt at a synthetic analysis of German castle architecture in the Gothic period presupposes the understanding that Germany in the late Middle Ages is not a political entity in the modern sense, but rather a “ patchwork” united essentially by a common language. This state of cultural affairs almost necessarily created a strong tendency to preserve local practices, even when new trends, like the Gothic style, were introduced from the outside and reworked regionally. German castle architecture can therefore only be treated region by region. Furthermore, because of the uneven state of research, the authors have chosen to concentrate on select regions that seem exemplary for their architectural forms and developments. Alsace, which is part of France today, but which was German speaking in the Middle Ages and an integral part of the Empire, is particularly interesting, having already embraced Gothic forms by the mid thirteenth century. In the Rhineland, Gothic art flourished in the fourteenth century. Most of the castles in Prussia and Livonia also date from this century, but they form a case apart, because of the mastery achieved by the Teutonic Order, whose structures are of remarkable quality. Finally, recent research has shown that the castles of Saxony are early castles for pleasure (Schlösser). They represent the end of the phenomenon in the fifteenth century, and mark the transition to the new programmes of the modern era.
I. Le Sud-Est de l’Allemagne
Authors: Bedal Konrad
Published: July 2015

Der Westen Deutschlands, von Klaus Freckmann

Die bauhistorische Situation des Rheinlandes ist von einer doppelten Situation geprägt – einerseits von dem Dilemma der hohen Verluste aufgrund des Zweiten Weltkrieges vor allem in Großstädten wie Köln, Aachen, Mainz, Koblenz oder Trier und andererseits aufgrund einer recht zielgerichteten Erforschung der mittelalterlichen Architektur in den letzten Jahrzehnten. Der Kenntnisstand der massiven Wohnhäuser (ab dem 13. Jh.) hat sich erheblich verbessert. Am Rhein, an der Mosel und in der Pfalz wurden mehrere Fachwerkbauten „ entdeckt“, die zumindest im Kern aus dem 14. Jh. stammen. Die Möglichkeiten der Dendrochronologie haben insbesondere den Forschungsstand erweitert und dem hiesiegen Baubestand zu einem genauen Datierungsgerüst verholfen. Das Rheinland ist eine der zentralen Kulturlandschaften Deutschlands und stellt zugleich ein Bindeglied mit dem Westen dar. Es wird immer deutlicher, dass die rheinische und (ost) französische Architektur in einem großen Zusammenhang stehen, was auch schon den französischen und auch den deutschen Architekturhistorikern des frühen 19. Jh. bewusst war. Auch dies sollten Gründe dafür sein, die gemeinsame architekturhistorische Forschung zu intensivieren, die letztlich nicht nur überregional, sondern auch übernational sein müsste -wie es auch einmal die mittelalterliche Welt war.
Le Trianon de Saint-Cloud : un autre Trianon de Porcelaine ?
Authors: Decrossas Michaël
Published: July 2015

Longtemps négligé ce petit pavillon élevé à l’extrémité du parc de Saint-Cloud, du côté de Sèvres et en surplomb de la Seine, fut pourtant célèbre en son temps. Construit entre 1670 et 1671, il resta inachevé. Seuls le corps central et l’un des pavillons furent bâtis, faisant perdre au bâtiment la symétrie du projet initial, connu par des gravures. L’élévation, d’un étage carré, était particulièrement original : le pavillon de plan rectangulaire aux angles arrondis était surmonté d’un toit terrasse au centre duquel ouvrait un attique couvert d’un dôme reprenant la forme du pavillon. Il abritait un salon à l’italienne. Dans le corps central, le décor avait été particulièrement soigné : dans la chambre et le cabinet, des carreaux de faïence pour les sols et les lambris à hauteur d’appui avaient été prévus, qui s’harmonisaient avec les meubles peints et les tentures mis en place. Le modèle en était clairement le Trianon de Porcelaine de Versailles. L’ensemble avait été réalisé sous la conduite de Thomas Gobert, qui en était l’entrepreneur. Mais, les dessins en avaient sans doute été donnés par l’architecte du frère du Roi, Antoine Le Pautre, auquel reviendrait ainsi l’invention du plan si particulier du pavillon abritant le salon.
Une Russie xénophobe : les dérives de l'idée nationale dans la Russie postsoviétique
Authors: Konovalova Tatiana
Published: July 2015

Since some twenty years ago, Russia has faced an increasing wave of xenophobic violence. Those engaged in committing such violence represent only a tiny minority of the Russian population. Nevertheless polices and the judicial system have not managed to stop them. The government in fact has been inefficient in its attempt to produce a substantial and coherent program, which could pacify inter-ethnic hostilities. These hostilities are the result of badly managed immigration and also the difficulties that the Russians have faced in rebuilding their national identity after the collapse of the USSR.
La représentation des Noirs dans la culture russe postsoviétique
Authors: Barta Peter I.
Published: July 2015

The article offers a quick survey of the history of producing Blackness within Russian epistemological space. It proposes that racism in Russia is tied up with unsuccessful attempts at nation building and, specifically, the failure of producing a satisfactory identity narrative for educational/propagandistic purposes. Following the loss of Empire and the lapse of the monopoly of the official rhetoric of the Communist Party, Russian culture has probed the question of empire and of the space of the Russian « civiliser » and the African « pupil ». Tolstaya, Lipskerov, Prokhanov and Lukinskii in the printed and visual media offer their takes on the question and it is the purpose of this essay to analyse and contextualise these.
Famille et altérité dans l'œuvre de Ludmila Oulitskaïa
Authors: Alaverdian Karine
Published: July 2015

Ludmila Ulitskaya is mainly concerned with the family and the other traditional Russian theme of « the little men ». Her favourite heroes, at first sight, seem weak and insignificant, and share a sense of otherness. This otherness, including their mental or physical handicap, is a source of internal freedom and of contempt for social conventions. In this article we will focus on the theme of the fear of otherness in the short stories of this Jewish writer. We reach the conclusion that the racism the writer experienced during her childhood in Stalin's Russia is still present today and that the situation of handicapped people is as difficult as ever. Unlike other writers of her period who are interested in the Jewish issue, Ulitskaya doesn't regard racism and anti-Semitism as genetically inherent characteristics of the Russian people, but as features, which depend on education received at home and in school.
Le regard de Gogol : du thème au concept
Authors: Breuillard Jean
Published: July 2015

Vision in Gogol's works :from theme to concept.

The purpose of the present paper is to demonstrate that the complete writings of Gogol are closely related to the theme of vision and glance : not merely his literary fiction, as has been noted by literary critics (distant vision vs. close vision, which focuses on details, a lack in depth perception, the myth of all-seeing eyes, changing points-of-view in order to approach reality, etc., but equally all other forms of writing (letters, historical and philosophical essays and so on). In the latter writings this theme uses exactly the same words, just slightly metaphorized, serving as a heuristic function of concepts and as tools of knowledge. The theme of vision and the glance is likely the « etymon » (Leo Spitzer) of Gogol's complete works.
Nicolaï Karamzine et la cathédrale de Strasbourg
Authors: Baudin Rodolphe
Published: July 2015

The article focuses on Nikolay Karamzin's depiction of the Strasbourg cathedral in Letters of a Russian Traveler. Even though it is very likely that the Russian writer did not personally visit the cathedral, since, at the time of his stay in Alsace, the city was overtaken by mutinous soldiers, Karamzin could not avoid describing one of Strasbourg's main landmarks in his travelogue. In order to do so, he had to turn to written sources, the identification of which is the first aim of the present paper. The second issue adressed here is that of Karamzin's aesthetic appreciation of the monument and of gothic architecture in general. Aware of the current aesthetic debate on Greek and Gothic styles fuelled by the ongoing British gothic revival, Karamzin appears to approve of the gothic structural design. Furthermore, he seems to have valued gothic churches as places where one can experience Burkean sublimity, and as an expression of the bold génie of Nordic peoples, to which the Russian traveler is proud to belong.
La vocation internationale de l'Université impériale de Strasbourg (1872-1914) : l'apport russe
Authors: Tikhonov-Sigrist Natalia
Published: July 2015

The article focuses on the presence of students from the Russian empire at Strasbourg Kaiser-Wilhelms University at the end of the 19th century - begining of the 20th. After establishing the number of students from Russia and the years they studied in Strasbourg, the author highlites their religious affiliation, social background and the topics they studied at the university. The article also adresses the place of women among the Russian students in Strasbourg, the students' relations with classmates from other countries and their unsuccessful attempt to build a community.
L'art alsacien dans l'œuvre des Russes émigrés des armées 1930 (Élisabeth Skobtsoff, Georges Fedotov, Wladimir Weidlé)
Authors: Victoroff Tatiana
Published: July 2015

During the 1930s, several Russian émigré writers visited Alsace. Among them were Elisabeth Skobtsoff, Georges Fedotov and Wladimir Weidlé. The first left a moving picture of the life of the Russian colony in Strasbourg. She also commented on the city's cathedral, using its gothic symbols as motives for a play she wrote on World War II. The other two extensively commented on Mathias GrUnewald's triptych, a major painting from the Renaissance representing Christ's crucifixion. The painting helped them elaborate some of their most profound thoughts on art, as well as on the contemporary history of the Western world, and the fate of living in exile.
Mises en scène d'une identité non slave de Russie : le théâtre komi dans un monde russe en mutation
Authors: Cagnoli Sébastien
Published: July 2015

The Komi, a Finno-Ugric people of North-Eastern Europe, have been part of Russia since the 14th century. After the Revolution, the Civil War led to the creation of a Bolshevik Komi State (1921), which later became an autonomous subject of Soviet Russia. Among intellectuals who remained in Russia, the 1920s and 1930s were times of optimism and creativity ; the national language became state language, and literature flourished in all genres. Later, with the 1990 declaration of sovereignty, the Komi State was to be transformed ; but after decades of russification, demographic and social realities were quite different from those of the time of the 1917 Revolution.

Undoubtedly Komi identity came particularly forward in these two decisive periods, and bilingualism played an important role in this process, though in different proportions. By exploring a literary genre with a wider potential audience - drama -, I intend to present some aspects of contemporary Komi cultural identity, especially in relation to their territory and language.

Effect of CO2 Exposure on Mechanical Resistivity of Cement Pastes with Incorporated Ceramic Waste Powder
Authors: Pokorný Jaroslav , Pavlíková Milena , Pavlík Zbyšek
Published: July 2015

Carbonation is chemical process associated with CO2 penetration into the material porous structure causing subsequent chemical changes in the structure of cement pastes. In this work, carbonation of several pastes containing varying amount of cement replacement by three waste ceramic powders is studied. Chemical composition of particular tested materials is accessed using XRF analysis. Matrix density, bulk density, total open porosity, compressive and bending strength are measured for all developed pastes with incorporated ceramic materials. Simultaneously, the effect of carbonation on these material properties is researched. The obtained results show significant improvement of materials mechanical strength due to the carbonation. Here, the measured compressive strength is typically about ~ 60% higher for materials exposed to CO2 rich environment compared to the materials cured in laboratory conditions.
Influence of Cracks on the Properties of Self-Compacting Concrete
Authors: Koňáková Dana , Koťátková Jaroslava , Vejmelková Eva
Published: July 2015

The paper deals with self-compacting concrete (SCC) and the change of its properties after exposure to thermal loading. Two types of microfillers were used (along with appropriate amount of superplasticizer) to gain concrete which would meet the requirements for SCC – limestone powder and fly ash. Specimens were subjected to temperatures of 600 °C for 2 hours. Results proved significant worsening of all studied parameters on samples after the thermal loading. Therefore studying of material exposed to different external conditions for better simulation of real life of construction is important in future research.
Mechanical and Thermal Properties of HSC with Fine Natural Pozzolana as SCM
Authors: Koťátková Jaroslava , Čáchová Monika , Vejmelková Eva , Reiterman Pavel
Published: July 2015

The article describes the influence of fine natural pozzolana as supplementary cementitious material on the properties of high strength concrete. Natural pozzolana (NP) is a porous material which results in higher porosities and thus lower compressive strength when used in high replacement levels. But if only a small part of cement (up to 10% of weight) is substituted by NP it has positive consequences. The open porosity is on the contrary lowered, resulting in better strength in compression. Thermal characteristics are as usually enhanced with the growth in the content of pores which is in disagreement of mechanical properties and durability of concrete.
Refractory Cement Composite Reinforced by Various Types of Fibers
Authors: Holčapek Ondřej , Reiterman Pavel , Jogl Marcel
Published: July 2015

Following article deals with experimental investigation of elevated temperatures influence on mechanical properties of refractory cement composite, which seems to be very progressive and interesting field of material science. Specimens 40 x 40 x 160 mm3 were exposed to 600 °C and 1000 °C for three hours. Using of aluminous cement, in this case Secar®71 with70 % of Al2O3, means the basic premise for refractory composites. Natural crushed basalt aggregate of two fractions 0-4 mm and 2-5 mm works as filler. Metakaolin MefistoL05 in amount 225 kg/m3 represents the fine filler, commonly used in refractory concrete production. Ceramic fibers or combination of two lengths of basalt fibers significantly improve the flexural characteristics. The goal of this research is to quantified influence of basalt fibers and ceramic fibers on flexural strength, compressive strength and bulk density of cement composite in high temperature conditions.
The Effect of Elevated Temperature on High Performance Fiber Reinforced Concrete
Authors: Fořt Jan , Pokorný Jaroslav , Citek David , Kolísko Jiří , Pavlík Zbyšek
Published: July 2015

High performance fiber reinforced concrete (HPFRC) became very popular material due to its high strength, elastic modulus, corrosion and fire resistance. However, detail description of HPFRC behaviour is necessary for its application and an effective building design and development. Here, also the fire safety of buildings must be considered. Therefore, the effect of elevated temperature on HPFRC is studied in the paper. For the reference material, experimental assessment of basic physical and mechanical properties is done. Then, the HPFRC samples are exposed to the temperatures of 600 and 800 °C respectively, and the effect of a high temperature exposure on material structure is examined. It is found that the applied high temperature loading significantly increases material porosity due to the physical, chemical and combined damage of material inner structure, and negatively affects also the pore size distribution.
The Experimental Testing of the Tensile Strength of the Steel Fibre Reinforced Cement Matrix
Authors: Machovec Jan , Vogel Filip , Konvalinka Petr
Published: July 2015

This article is focused on state of knowledge about experimental testing of uniaxial tension strength of specimens from cement-based composites. We searched for various types of experimental testing of tensile strength, shapes of specimens or type of reinforcement. There is our own experimental program at the end of this article. Our aim is to find the best way to test steel fibre reinforced cement matrix for textile reinforced concrete in oneaxial tension. Textile reinforced concrete has many advantages (e.g.: no covering layer, higher ductility) and may be used instead of common steel reinforced concrete or as a method to repair old structures (e.g.: to bind columns).
Ceramic Waste Powder as an Active Pozzolanic Material for Cement Based Composites
Authors: Kulovaná Tereza , Pavlík Zbyšek
Published: July 2015

Parameters of cement pastes with ceramic powder as partial Portland cement replacement up to 40 mass% are presented in the paper. Ceramic powder belongs to the pozzolanic materials. Utilization of pozzolanic materials is accompanied by lower request on energy needed for Portland clinker calcination which generally results in lower production costs of blended binder and lower CO2 emissions. The ceramic powder is used in cement based pastes composition in amount of 8, 16, 24, 32, and 40 mass% of cement. For the studied ceramic powder, chemical composition is measured by X-Ray Fluorescence. The particle size distribution of ceramics is accessed on laser diffraction principle. Bulk density, matrix density, and total open porosity are measured for 28 days cured paste samples. The obtained results demonstrate that ceramic powder has potential to replace a part of Portland cement in composition of cement based composites.

Background

The scheduling of residents for rotation assignments and on-call responsibilities is a time-consuming process that challenges the resources of residency programs. Assignment of schedules is traditionally done by chief residents or program administration with variable input from the residents involved.

We introduced an innovative point-based scheduling system to increase transparency in the scheduling process, foster a sense of fairness and equality in scheduling, and increase resident ownership for making judicious scheduling choices.

Methods

We devised a point-based system in which each resident in our 40-member program was allocated an equal number of points. The residents assigned these points to their preferred choices of rotations. Residents were then surveyed anonymously on their perceptions of this new scheduling system and were asked to compare it with their traditional scheduling system.

Results

The schedule was successfully implemented, and it allowed residents to express their scheduling preferences using an innovative point-based approach. Residents were generally satisfied with the new system, would recommend it to other programs, and perceived a greater sense of involvement. However, resident satisfaction with the new system was not significantly greater compared with the previous approach to scheduling (P = .20). Chief residents expressed satisfaction with the new scheduling model.

Conclusions

Residents were equally satisfied with the traditional preference-based scheduling approach and the new point-based system. Chief residents' feedback on the new system reflected reduced stress and time commitment in the new point-based system.

Published: July 2015

Background

There is no standard way to help residents deal with the emotional impact of patient deaths. Most available curricula are time and resource intensive.

Objective

We introduced “Patient Death Debriefing Sessions” into an inpatient medical oncology rotation at Memorial Sloan Kettering Cancer Center to provide a structured yet practical way to address residents' emotional reactions following the death of a patient. A questionnaire was used to evaluate the impact of these sessions.

Methods

Patient Death Debriefing Sessions consist of a brief (~10 minutes), real-time (within 24–48 hours), consistent (following each death), attending physician–led debriefing that focuses on internal medicine residents' emotional reactions following patient deaths. Sessions were guided by a pocketcard tool and did not require faculty training. Residents completing a 4-week medical oncology rotation were surveyed before and after their rotation. Prerotation and postrotation mean differences were evaluated based on the number of sessions they participated in (0 to ≥ 3) using analyses of variance.

Results

Ninety-one of 92 participants spanning all training levels completed questionnaires (99% response rate). Of these, 79 (87%) encountered a patient death and were included in the analyses. Overall, residents found debriefing sessions helpful, educational, and appreciated attending physician leadership. The number of debriefing sessions positively influenced residents' perception of received support.

Conclusions

This high-yield, novel pilot curriculum supported residents' emotional reactions to patient deaths and may foster communication with team members, including supervising attending physicians. This program is easily implemented and could be adapted for use in other clinical settings.
Duty Hour Reporting: Conflicting Values in Professionalism
Authors: Byrne John M. , Loo Lawrence K. , Giang Dan W.
Published: July 2015

Background

Duty hour limits challenge professional values, sometimes forcing residents to choose between patient care and regulatory compliance. This may affect truthfulness in duty hour reporting.

Objective

We assessed residents' reasons for falsifying duty hour reports.

Methods

We surveyed residents in 1 sponsoring institution to explore the reasons for noncompliance, frequency of violations, falsification of reports, and the residents' awareness of the option to extend hours to care for a single patient. The analysis used descriptive statistics. Linear regression was used to explore falsification of duty hour reports by year of training.

Results

The response rate was 88% (572 of 650). Primary reasons for duty hour violations were number of patients (19%) and individual patient acuity/complexity (19%). Junior residents were significantly more likely to falsify duty hours (R = −0.966). Of 124 residents who acknowledged falsification, 51 (41%) identified the primary reason as concern that the program will be in jeopardy of violating the Accreditation Council for Graduate Medical Education (ACGME) duty hour limits followed by fear of punishment (34, 27%). This accounted for more than two-thirds of the primary reasons for falsification.

Conclusions

Residents' falsification of duty hour data appears to be motivated by concerns about adverse actions from the ACGME, and fear they might be punished. To foster professionalism, we recommend that sponsoring institutions educate residents about professionalism in duty hour reporting. The ACGME should also convey the message that duty hour limits be applied in a no-blame systems-based approach, and allow junior residents to extend duty hours for the care of individual patients.
Multi-instrument gravity-wave measurements over Tierra del Fuego and the Drake Passage – Part 1: Potential energies and vertical wavelengths from AIRS, COSMIC, HIRDLS, MLS-Aura, SAAMER, SABER and radiosondes

Abstract. Gravity waves in the terrestrial atmosphere are a vital geophysical process, acting to transport energy and momentum on a wide range of scales and to couple the various atmospheric layers. Despite the importance of these waves, the many studies to date have often exhibited very dissimilar results, and it remains unclear whether these differences are primarily instrumental or methodological. Here, we address this problem by comparing observations made by a diverse range of the most widely-used gravity wave resolving instruments in a common geographic region around the southern Andes and Drake Passage, an area known to exhibit strong wave activity. Specifically, we use data from three limb-sounding radiometers (MLS-Aura, HIRDLS and SABER), the COSMIC GPS-RO constellation, a ground-based meteor radar, the AIRS infrared nadir sounder and radiosondes to examine the gravity wave potential energy (GWPE) and vertical wavelengths (λz) of individual gravity wave packets from the lower troposphere to the edge of the lower thermosphere. Our results show important similarities and differences. Limb sounder measurements show high intercorrelation, typically > 0.80 between any instrument pair. Meteor-radar observations agree in form with the limb sounders, despite vast technical differences. AIRS and radiosonde observations tend to be uncorrelated or anticorrelated with the other datasets, suggesting very different behaviour of the wave field in the different spectral regimes accessed by each instrument. Except in spring, we see little dissipation of GWPE throughout the stratosphere and lower mesosphere. Observed GWPE for individual wave packets exhibits a log-normal distribution, with short-timescale intermittency dominating over a well-repeated monthly-median seasonal cycle. GWPE and λz exhibit strong correlations with the stratospheric winds, but not with local surface winds. Our results provide guidance for interpretation and intercomparison of such datasets in their full context, and reinforce the vital point that no one dataset can represent the whole spectrum of gravity waves in the terrestrial atmosphere.

Sweetpotato is used in various food preparations in place of rice, cassava, yam and plantain in Ghana. In spite of this it does not have the same importance in Ghanaian diet as other root and tuber crops. Consumer taste, preference and acceptance are critical in determining the suitability of sweetpotato cultivars to any locality. A study was carried out in some selected communities of Ghana where sweetpotato is popular which span all five ecozones of Ghana in February, 2012. The main objective was to investigate why sweetpotato has low utilization compared with other root and tuber crops and to increase its utilization through breeding. The study employed Focus Group Discussion (FGD) followed by administration of Semi-structured Questionnaire (SSQ). Data collected were analysed using Genstat and Statistical Package for Social Sciences. Seventy-nine people consisting of 63% males and 37% females, and 178 people consisting of 52% female and 48% males were involved in the FGD and SSQ, respectively. Majority (94%) of farmers’ ranked sweetpotato from 1 to 5 among 24 cultivated crops. Only about 28% of consumers ate sweetpotato at least six days per week. The survey revealed that consumers in Ghana desired non-sweet, high dry matter sweetpotato cultivars. Therefore, there is need for Research and Development to adjust sweetpotato breeding objectives and selection procedures to develop high dry matter non-sweet sweetpotato varieties in Ghana.
Teología política y Modernidad: Peterson, Blumenberg y Schmitt
Authors: Navarrete Alonso Roberto
Published: July 2015

El presente artículo trata de dilucidar el significado del sintagma «teología política» en el pensamiento de C. Schmitt conforme a lo postulado por éste en su homónima doctrina de la soberanía. Para ello se tendrán en cuenta las negaciones teológica (Peterson) y científico-filosófica (Blumenberg) de la propuesta schmittiana, así como la respuesta dada por Schmitt a ambas en Teología política II. Tratará de mostrarse así que la teoría schmittiana de la secularización, tal y como ésta fuera postulada en 1922, no lleva a cabo una teologización de la política sino que, por el contrario, presupone la muerte de Dios y, en este sentido, afirma la secularidad intrínseca de la Modernidad.
¿Popper aristotélico? Logos, crítica y sociedad abierta
Authors: Chillón José Manuel
Published: July 2015

Este artículo trata de investigar en qué medida la filosofía práctica de Aristóteles puede ofrecer un fundamento sólido a la filosofía popperiana, en especial a su interés por fundar una democracia en términos de sociedad abierta. Propongo que se entienda la sociedad abierta, siguiendo a Aristóteles, como aquella comunidad política en la que, al poder ser de otra manera, cabe la deliberación, la discusión, la crítica y, por tanto, la capacidad de construir un futuro determinado sólo por lo que los hombres quieran hacer con su libertad. Si esto fuera así, a la racionalidad y a la sociabilidad, como notas distintivas de la especificidad de lo humano según Aristóteles, podría sumarse la concepción popperiana de la apertura.

Published: July 2015

La investigación trata de analizar la presencia de complicaciones en los pacientes diabéticos y no diabéticos sometidos a cirugía cardíaca. Estudio analítico de corte transversal. Se incluyeron 50 pacientes sometidos a cirugía cardíaca y se analizaron según la presencia o ausencia de diabetes mellitus, cada grupo contiene 25 pacientes. La recolección de datos se realizó mediante el análisis de la historia clínica del paciente. De los 30 procedimientos quirúrgicos fueron CABG (60 %), TRVA 11 (22%), TrVM 6 (12 %), CRM TRVA + 1 (2 %), TRVA TrVM + 1 (2 %) y TRVA TRVP + 1 (2%). La población del estudio tenía una edad media de 60,4 años en el grupo de diabéticos y 56 años en el grupo de no diabéticos. En cuanto a los factores de riesgo, la hipertensión 19 (76,0 %) tenía diferencias que prevalecen en el grupo de diabéticos. En cuanto a las complicaciones postoperatorias se observó un mayor número de complicaciones hemodinámicas y respiratorias entre el postoperatorio inmediato hasta el tercer día del postoperatorio en ambos grupos. A partir de las  respuestas se puede decir que no existen diferencias estadísticamente significativas entre las variables, por lo tanto, llegamos a la conclusión de que la diabetes mellitus, solo, no fue un factor agravante de la cirugía trans y post- cardiaca.
