Wang Chongs (27-ca. 100) Divinationskritik
Authors: Gentz Joachim
Published: July 2011

Divinationskritik findet sich spätestens vom vierten Jahrhundert an in frühen chinesischen Quellen. Sie richtet sich niemals grundsätzlich gegen Divination, sondern immer nur gegen einzelne falsche Divinationsformen, die zu irrigen Voraussagen führen. Die historiographische Literatur geht davon aus, dass sich auf der Grundlage historischer Präzedenzien Voraussagen menschlicher Handlungen treffen lassen und veranschaulicht an historischen Einzelbeispielen Fälle richtiger oder falscher Voraussagen. Historiographie und Divination stehen sich daher nahe. Wang Chong ist der erste Denker Chinas, der systematisch kritisch über Divination reflektiert. Er entwirft eine Theorie, nach der sich menschliches Schicksal als Ergebnis des Zusammenspiels unterschiedlicher Kräftefelder spontan und unabhängig von der moralischen Qualität menschlichen Handelns ergibt. Da Zukunft bei Wang in der Gegenwart angelegt ist und nach bestimmten Gesetzmäßigkeiten keimt und sich realisiert, ist sie Weisen und Gebildeten, welche diese Gesetzmäßigkeiten kennen, einsichtig. Sie wird von ihnen an Zeichensystemen wie dem des menschlichen Körpers (Physiognomie), des Himmels (Astrologie) oder der Natur (Omina), welche korrelativ aufeinander bezogen verstanden werden, erkannt. Die Bedingung für ein richtiges Ausdeuten der Zukunft bildet nicht seherische oder übernatürliche Befähigung, sondern Einsicht in die Entwicklungsgesetze des Kosmos, die nur durch Studium und Gelehrsamkeit erlangt werden kann.
La divination dans les Vies romaines de Plutarque : le point de vue d’un philosophe
Authors: Stoffel Éliane
Published: July 2011

This paper tries to analyse how a Greek intellectual of the Roman Empire deals with the Roman way to communicate with gods, and more precisely with Roman divination. Plutarch’s point of view is conditioned by his philosophical background (he is a middle platonist) and his political reflexion on the Roman Empire and its success; at the same time, he never forgets the necessities of biographical narration, the importance of traditions and his learned readers’ expectations. We’ll see that in the Lives also (and not only in the Moralia) we can find accounts of the philosophical discussions of the time and that, from one biography to another, his material is carefully selected and very coherently constructed, so that the augur becomes the central figure of the Roman divinatory system, and maybe of the whole religious system. His readers are led to think about two correlated things: the careful dealing with the Roman gods of Aemilius Paullus, for example, and the reasons why he suggests them such a model. We should not forget that Plutarch himself, as a priester in Delphi for long years, was very involved in the Greek ways of divination; that is why his reflexion on the Roman ways of divination is the more meaningful.
An Assessment of Hotel Product Quality in Kenya as a Basis for Building Destination Competitiveness
Authors: Wadawi Joe Kibuye , Bresler Nerine C. , Herbst Frikkie J.
Published: July 2011

Developing countries such as Kenya and other African countries now consider tourism as a passport for development as it does not need expensive investment to initiate and operate as a national business. This study was motivated by the need to create parameters that can elevate the competitiveness
of a tourist destination. The purpose was to initiate the formulation of a structured, integrated conceptual framework for hotel product/service, quality based on the normative quality expectation of the tourists and Hotel Operators' strategic quality designs. Descriptive qualitative research
design was used to establish the secondary objectives and to assess the five propositions that were developed for the study. Tourists and hotel operators in two major tourist provinces of Kenya were used to obtain information regarding normative and perceptive hotel product/service quality.
Destination marketing managers employed by the only destination marketing organization, Kenya Tourist Board (KTB), were also surveyed to provide insight on Kenya's destination marketing strategies. The study found that hotel operators and other destination management organizations neither
share nor operate on a common vision as they endeavor to build destination competitiveness for Kenya. An integrated framework that may be utilized to build destination competitiveness so that the economic potential of tourism is maximized in Kenya is therefore proposed.
Tourism Trends in Ghana: The Accommodation Sector
Authors: Mensah-Ansah Joseph , Martin Emma , Egan David
Published: July 2011

Tourism in Ghana has become a major socioeconomic activity and one of the most important and fastest growing sectors of the Ghanaian economy. It is the fourth largest foreign exchange earner after cocoa, gold, and remittances from abroad. Ghana's tourism growth rate is about 12% per
annum. Hence, the importance of tourism and its sociocultural, political, and economic values to Ghana is enormous. The tourism industry has over the years demonstrated its ability to contribute significantly towards national economic development, especially in the areas of employment generation,
wealth creation, and poverty reduction at national and community levels. Since independence in 1957, a number of tourism development plans has been drawn up to guide the growth of the industry. Unfortunately, none of these plans has been fully implemented due to unfavorable economic and political
environment. Although most sections of Ghana's tourism development plans since independence have not been fully implemented, the tourism sector in Ghana has seen substantial growth. The government is determined to reap the full benefits that the industry offers by putting in place necessary
plans, policies, actions, and resources to stimulate guided growth in the sector and ensure that tourism does not become a missed opportunity. This article gives an overview of tourism in Ghana; in particular, the demand and supply trends in the accommodation sector. It also examines the contribution
of the accommodation sector to the Ghanaian economy.
Efficacy and Safety of CH-1504, a Metabolically Stable Antifolate, in Patients with Active Rheumatoid Arthritis: Results of a Phase II Multicenter Randomized Study
Authors: KEYSTONE EDWARD C. , SHIRINSKY VALERY S. , SIMON LEE S. , PEDDER SIMON , HEWITT L. ARTHUR ,   the CH-1504 Study Group
Published: July 2011

Objective.

To investigate the potential efficacy, safety, and tolerability of daily use of CH-1504 in patients with active rheumatoid arthritis (RA). US National Institutes of Health database no. NCT00658047.

Methods.

In our phase II randomized double-blind double-dummy study, patients naive to methotrexate (MTX; n = 201) and having moderate to severe RA received either CH-1504 (0.25 mg, 0.5 mg, or 1.0 mg once-daily oral doses) or MTX (titrated to 20.0 mg once-weekly oral doses). All received weekly 10-mg folate supplementation. Efficacy and safety were assessed at 2, 4, 8, and 12 weeks, with a treatment-free followup at 16 weeks. Safety and tolerability were assessed. Primary efficacy endpoint was proportion of patients achieving ACR20 response at Week 12. Secondary endpoints included difference from baseline in the 28-joint Disease Activity Score (DAS28) and individual components of the American College of Rheumatology (ACR) composite index.

Results.

Demographic characteristics were similar in all treatment groups: mean age 54.3 ± 11.4 years, female sex 87%, mean baseline DAS28 6.6 ± 0.9. At Week 12, CH-1504 demonstrated comparable efficacy compared to MTX as measured by ACR20, DAS28, and ACR composite core-set measures, including tender and swollen joints. No dose-response relationship was observed. Adverse events across treatment groups were mild. Liver enzyme levels increased from baseline to Week 16 in the MTX group, with qualitatively lesser increases in the CH-1504 groups. Two patients in the MTX group withdrew because of gastrointestinal-related adverse events. CH-1504 appeared safe and well tolerated at all dose levels.

Conclusion.

CH-1504 has comparable efficacy to MTX and is safe and well tolerated. Metabolically stable antifolates are a promising therapeutic option that warrants further study.

Authors: McKELLAR GAYLE E. , HAMPSON ROSEMARY , TIERNEY ANN , CAPELL HILARY A. , MADHOK RAJAN
Published: July 2011

Objective.

To evaluate the effect of nonsteroidal antiinflammatory drug (NSAID) withdrawal on blood pressure (BP), 44-joint Disease Activity Score (DAS44), and functional assessments in patients with stable rheumatoid arthritis (RA).

Methods.

NSAID was withdrawn from 30 patients with stable RA (DAS44 ≤ 2.8). Other prescribed medication continued. Clinical and laboratory measures were taken at baseline, 6 weeks, and 12 weeks.

Results.

No participants required NSAID reintroduction during the study period. Significant improvement in systolic BP was noted: maximal median reduction was 7 mm Hg (baseline to 12 weeks). There was no significant deterioration in DAS44 or function. Eleven participants required additional intervention.

Conclusion.

NSAID withdrawal resulted in improvement in BP without loss of disease control.
Expression of APRIL in Diffuse Large B Cell Lymphomas from Patients with Systemic Lupus Erythematosus and Rheumatoid Arthritis
Authors: LÖFSTRÖM BJÖRN , BACKLIN CARIN , PETTERSSON TOM , LUNDBERG INGRID E. , BAECKLUND EVA
Published: July 2011

Objective.

Patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) have an increased risk of diffuse large B cell lymphoma (DLBCL). The cytokine A PRoliferating-Inducing Ligand (APRIL) is strongly expressed in DLBCL in the general population and is detected in high concentrations in sera from subgroups of patients with RA and SLE. To investigate a possible association between APRIL and DLBCL in RA and SLE, we examined APRIL expression in lymphoma biopsies from patients with RA and SLE and from DLBCL patients without inflammatory disease.

Methods.

Lymphoma tissue from 95 RA, 12 SLE, and 63 comparator DLBCL cases were stained with anti-APRIL antibodies (Aprily-2). The percentage of positively stained cells of the comparator cases were divided into quartiles (1–4, where 4 = most stained) and compared with the results for the RA and SLE lymphomas. APRIL expression was correlated to clinical variables.

Results.

The odds ratio for high expression of APRIL (quartiles 3 and 4) was elevated in the SLE DLBCL (OR 23.6, 95% CI 2.4–231.2), but not in the RA DLBCL (OR 0.8, 95% CI 0.3–2.0). RA patients in quartile 4 had higher cumulated RA disease activity than those in quartile 1 (p = 0.013). Epstein-Barr virus in the lymphoma tissue was associated with high APRIL expression (p = 0.009).

Conclusion.

The high expression of APRIL in DLBCL in SLE and in an RA subset might indicate an association between APRIL and lymphoma in these subsets of rheumatic diseases, but could also reflect a dysregulation of APRIL per se in these patient groups.
Soluble Receptor for Advanced Glycation Endproducts Is Decreased in Patients with Juvenile Idiopathic Arthritis (ERA Category) and Inversely Correlates with Disease Activity and S100A12 Levels
Authors: MYLES ARPITA , VISWANATH VISHAD , SINGH YOGESH PREET , AGGARWAL AMITA
Published: July 2011

Objective.

Membrane-bound receptor for advanced glycation endproducts (mRAGE) is overexpressed in response to increasing concentrations of its ligand (e.g., S100A12) and triggers an inflammatory immune response. In contrast, soluble RAGE (sRAGE) acts as a decoy receptor and downmodulates inflammation. Decreased sRAGE levels are associated with autoimmune diseases; however, limited data are available in juvenile idiopathic arthritis (JIA). We studied sRAGE levels in patients with JIA [enthesitis-related arthritis (ERA) category].

Methods.

sRAGE levels were estimated in the serum of patients with ERA JIA (n = 101), systemic-onset JIA and polyarticular JIA (n = 10 each), and healthy controls (n = 45). Synovial fluid (SF) sRAGE was measured in patients with ERA, rheumatoid arthritis, reactive arthritis, and osteoarthritis (n = 10). Levels of S100A12 were also measured. Twenty-four patients with ERA were followed for 4 months. Disease activity was assessed by swollen joint count (SJC), tender joint count (TJC), and erythrocyte sedimentation rate (ESR). All levels are expressed as median (range).

Results.

The serum sRAGE (pg/ml) level was significantly lower in patients compared to healthy controls [515 (64–1887) vs 1542 (627–3159); p < 0.0001]. In paired samples, SF had lower levels compared to corresponding plasma level [102 (51–799) vs 481 (134–1006); p < 0.0001]. The level of S100A12 (ng/ml) was higher in SF (1042; 573–1415) than serum (638; 208–779). Serum sRAGE correlated negatively with S100A12 levels (r = −0.474; p < 0.01.), ESR (r = −0.306; p < 0.01), and SJC (r = −0.237; p < 0.05), but not with TJC (r = −0.134; p = NS). The levels of sRAGE remained stable over time in patients with stable disease.

Conclusion.

Levels of sRAGE are reduced in patients with ERA and correlate negatively with disease activity and S100A12 levels. sRAGE may be a modulator of inflammation in these patients.
Ferdinand Tönnies, sociologue empiriste
Authors: Zimmermann Bénédicte
Published: July 2011

Résumé Ferdinand Tönnies est surtout connu en France pour sa contribution à la théorie sociologique. Rarement relevé, son engagement en faveur de la sociologie empirique participe pourtant d’un débat central de l’histoire des sciences sociales allemandes de l’après Première Guerre mondiale. Dans le texte « Statistique et sociographie », écrit en 1928 mais traduit ici pour la première fois en français, Tönnies livre un vibrant plaidoyer en faveur d’une science empirique du social qu’il appelle la sociographie. Un premier trait marquant de ce plaidoyer est qu’il intervient à contre-courant du rempli théorique qui marque alors la sociologie allemande naissante ; un second est qu’il dénonce la prétention de la statistique à satisfaire l’ensemble des exigences d’une science empirique du social et appelle à l’articulation entre méthode quantitative et qualitative, approche déductive et inductive. Tout en donnant accès à un pan original de l’œuvre de Tönnies et à une meilleure connaissance de sa sociologie, ce texte offre un témoignage historique sur la constitution des disciplines de sciences sociales en Allemagne. Enfin, il alimente un débat épistémologique majeur, dont l’actualité reste aujourd’hui entière, sur le statut et les usages de la statistique.
Proust ethnographe et policier symbolique
Authors: Pouly Marie-Pierre
Published: July 2011

Résumé Dans la deuxième partie du XIX e siècle, la combinaison de l’expansion industrielle et commerciale britannique, de la diffusion progressive des voyages et de l’enseignement des langues vivantes, y compris auprès de la petite bourgeoisie, contribue à étendre le nombre et le type d’agents susceptibles de manipuler les choses anglaises, bien linguistique et symbolique dont l’aristocratie possédait antérieurement le quasi monopole. À condition de mettre au jour les conditions sociales de possibilité de l’hypersensibilité linguistique qui porte Marcel Proust, ethnographe et sociolinguiste (avant l’heure) des classes dominantes entre les années 1870 et 1920, à l’objectivation des stratégies de distinction linguistique de ses contemporains, on peut voir dans À la recherche du temps perdu un document précieux pour rapporter les transformations de l’usage des choses et des mots anglais aux transformations de l’espace social et de ses modes de reproduction, notamment scolaires.
Paysage-lumière et environnement urbain nocturne
Authors: Mallet Sandra
Published: July 2011

Résumé Les nuits urbaines françaises se transforment fortement depuis une trentaine d’années. En parallèle, les discours autour de l’urbanisme-lumière font consensus auprès des acteurs de l’éclairage public et semblent acheminer les villes vers des éclairages plus qualitatifs et conçus à une échelle plus large. Dans ce cadre, nous interrogeons les manières dont est traitée la pollution lumineuse au sein des espaces urbains. Il ressort de nos analyses menées à Paris, Saint-Denis et Bordeaux des confusions régnant autour de cette expression et des moyens réduits et quasi exclusivement technicistes pour parvenir à la diminuer. L’hypothèse est que cela est lié à des réflexions se positionnant en termes de paysage et non d’environnement nocturne, délaissant alors certains aspects du fonctionnement des espaces urbains nocturnes. Des exemples pris autour des usages spatiaux et pouvant participer à une meilleure maîtrise de cette pollution sont alors mis en évidence.
Paysage et environnement : une poétique commune
Authors: Mousquet François-Xavier , Pousin Frédéric , Delbaere Denis
Published: July 2011

Résumé En tant que paysagiste, François-Xavier Mousquet accorde à la dimension environnementale du projet de paysage une grande importance. Les terrains sur lesquels il a été amené à travailler avec l’agence Paysage conditionnent une telle approche. Plusieurs opérations de reconversion de terrils du Nord-Pas de Calais, engagées dès le milieu des années 1980, sont commentées du point de vue des méthodes combinant écologie et paysage. Celles-ci permettent d’appréhender les friches comme des espaces non plus figés, mais en constante transformation, faisant sens pour les populations locales. L’aménagement de la station d’épuration par lagunage de la ville de Harnes constitue, en outre, une expérience plus conflictuelle. Le dernier projet commenté est le concours pour l’aménagement des abords de la citadelle de Lille où le parti développé a permis une véritable osmose entre des expertises a priori très différentes.
Gouverner par les normes environnementales : jeux d'acteurs et de puissance dans la certification forestière
Authors: Tozzi Pascal , Guéneau Stéphane , Ndiaye Abdourahmane
Published: July 2011

Résumé Le champ environnemental international est un lieu important d’émergence de dispositifs privés de normalisation et de certification visant à encadrer les actions et les pratiques des acteurs. Envisagés comme des instruments de gouvernance et de négociation, ces dispositifs se voient souvent attribuer une forte légitimité démocratique de même qu’un potentiel régulatoire et « pacificateur » élevé au sein du jeu forestier international. Pourtant ce dernier révèle des persistances conflictuelles, parfois sous-tendues par les dispositifs et les processus de certification eux-mêmes. Il s’agit donc de réintroduire dans l’analyse des interactions les variables du pouvoir et de la puissance, de prendre en compte les stratégies et jeux d’acteurs – privés ou publics – et les enjeux conflictuels de captation, de maîtrise des processus de normalisation environnementale à l’œuvre en matière forestière.
L'aménagement territorial du Pays d'Aunis : entre conflits d'intérêts et concertation
Authors: Bossuet Luc , Guy Roland , Léger François
Published: July 2011

Résumé Le présent article vise à mettre en évidence la diversité des modalités d’anticipation utilisées par les acteurs décisionnels (les élus) pour assurer l’aménagement des territoires dont ils ont charge de gestion. En France, la loi relative à la solidarité et au renouvellement urbain de décembre 2000 instaure deux outils de gestion ; les Schémas de cohérence territorial ( scot ) et les Plans locaux d’urbanisme ( plu ) ainsi qu’une méthode qui consiste à mettre en place différentes phases de concertation entre acteurs. L’étude menée sur la base d’entretiens qualitatifs auprès d’élus, d’agriculteurs et d’administratifs, associés à des récits de vie prenant en compte les histoires locales et la consultation de documents d’urbanisme permet de mettre en évidence de réelles différences entre collectivités territoriales quant à l’application de la législation en vigueur. Cette diversité offre en retour l’occasion de s’interroger sur la façon dont les acteurs en présence conçoivent l’information, la concertation et la négociation.
Photosynthetic response and zonation of three species of Gelidiales from Tenerife, Canary Islands
Authors: Domíguez-Álvarez S. , Rico J. M. , Gil-Rodríguez M. C.
Published: July 2011

Three species of Gelidiales (Gelidium arbuscula, Gelidium canariense and Pterocladiella capillacea) (Rhodophyta) were selected due to their abundance in the marine lower intertidal of the north coast of the island of Tenerife (Canary Islands), to assess, using PAM fluorescence, the importance of irradiance and exposure to air on vertical distribution. We compared tolerance to emersion by air-drying fronds under simulated emersion, and results suggest that recovery of photosynthesis after emersion plays a major role in the vertical distribution of these three species. Morphological traits such as clumped fronds explain the higher tolerances, and reduced water loss of the species upper on the shore. Local differences between sites may be related to slight differences in the light regime related to topography.

Test Method with Small Samples of Electro-Explosive Devices Based on Information Equivalence Principle
Authors: Wang Yao Hua , Wang Liang , Yang Hai Shan , Zhu Bao Guo
Published: July 2011

In order to solve the problem which generally exists in assessing high explosive ignition reliability of electro-explosive devices (EED), a new test method, based on information equivalence principle, is proposed on the condition of a relatively smaller sample size for instead. According to the definition of information principle, the method measures the reliability test information by the negative logarithm of ignition probability of EED and converts the test by GJB376-1987 at a larger amount of stimulation with a big sample size to a small one. We adopt this method to assess the ignition reliability of EED used in the emergency opening system. The result is that we just need 29 sample size on the confidence of not less than 95% and the ignition reliability greater than 0.999. Compared with the 2996 sample size in GJB376-1987, the method reduces the sample usage greatly. Tests shows that the small sample test method based on information equivalence principle for the ignition reliability test of EED is accurate, feasible and can meet the objective of experimental design

Authors: Men Shou Qiang , Resagk Christian
Published: July 2011

A simple calibration system for magnetic field sensors was designed, and experiments were carried out to calibrate two-dimensional fluxgate sensors and a sensor ring composed of eight fluxgate sensors. Fast Fourier Transforms and trapezoidal numerical integrals were applied to deal with the raw signals. It is found that it is not suitable to apply fast Fourier Transforms only to deal with signals with several peaks close to each other, but trapezoidal numerical integrals should also be used in combination with the FFT method.
