Persistent descending mesocolon: Case report
Authors: Trebjesanin Zoran , Babic Srdjan , Vucurevic Goran , Popov Petar , Ilijevski Nenad , Blagotic Milena
Published: November 2012

Introduction. Positional anomalies of the right half of the colon are quite
common whereas positional anomalies of the left half of the colon are much
less common because of embryological disorders during the period of the
embryological development of that part of the bowel. The process of the
fixation of the descending colon to the posterior abdominal wall can be
absent. In that case, when the descending colon has a free descending
mesocolon, it shows some degree of mobility. Case Outline. We are presenting
an example of one of the anomalies, which is characterized by the persistent
descending mesocolon, which extends from the splenic flexure or just below it
to the sigmoid colon. The persistent descending mesocolon in our case
contains or surrounds almost complete small bowel in a recess which is
located laterally to the left of the midline. The content of this hernial sac
simulates the symptoms of an internal hernia followed by clinical symptoms
and roendgenographical signs. Conclusion. We are of the opinion that this
anomaly is more common than some surveys of literature would suggest.

Published: November 2012

Introduction. Treating severe acute glyphosate-surfactant poisoning requires
intensive therapy including dialysis. Cases of hemoperfusion and hemodialysis
use in renal failure induced by herbicide ingestion have been reported in the
current medical literature. We present a case report of successful patient
treatment with continuous venovenous hemodiafiltration in acute
glyphosate-surfactant poisoning. Case Outline. A 36-year-old male patient
attempted suicide by drinking approximately 300 ml of glyphosate-surfactant
about an hour before coming to our Clinic. On admittance the patient was
somnolent, normotensive, acidotic and hyperkalemic. Six hours after poison
ingestion there was no positive response to symptomatic and supportive
therapy measures. The patient became hypotensive, hypoxic with oliguric acute
renal failure, so that post-dilution continuous veno-venous hemodiafiltration
was started. During the treatment the patient became hemodinamically stabile,
diuresis was established along with electrolyte and acid-base status
correction and a gradual decrease of blood urea nitrogen and creatinine
levels. After a single 27.5-hour treatment, clinical condition and renal
function parameters did not require further dialysis. Complete recovery of
renal function was achieved on the fifth day. Conclusion. Early introduction
of continuous veno-venous hemodiafiltration with other intensive therapy
measures led to complete recovery in a hemodinamically instable patient.
Family outbreak of cryptosporidiosis in Serbia: Case report
Authors: Gvozdenovic Eleonora , Mitrovic Nikola , Dakic Zorica , Stojkovic-Svirtlih Neda , Dulovic Olga
Published: November 2012

Introduction. Cryptosporidiosis is an acute infectious parasitic disease of
the gastrointestinal tract, considered as zoonosis underestimated in
immunocompetent population. The pathogen is primarily the cause of
devastating diarrhea in AIDS patients. Solitary cases and small outbreaks in
immunocompetent persons are rarely discovered. There is also a human strain
of cryptosporidium. Case Outline. In December 2010, we examined three family
members among whom each successively developed acute gastroenteritis. Their
stools were liquid, light brown, without mucus or blood. All of them had
abdominal cramps and generalized muscle pains. The daughter had fever and
vomited during the first two days. The patients were administered symptomatic
therapy. Complaints resolved after 10-17 days, with general condition
moderately changed. Cryptosporidium was confirmed in the stool of patients
who were second and third to contract the disease. We presumed that the first
person released pathogen before the time of examination, although she still
had diarrhea. All of them recovered completely. By epidemiologic survey we
were unable to presume with certainty the source of infection. Conclusion.
This is the first description of cryptosporidiosis in immunocompetent
individuals in Serbia, which proves that it is present in our country, and
that search for it should be included into a routine parasitological check-up
of stool. Taking into account the distance in onset time complaints, all
combinations are possible; from infection among family members (shortest
incubation period) to family members infected from an identical source
(different incubation period). Negative finding of the sample collected on
the 7th day from the beginning of symptoms does not exclude the diagnosis in
this particular situation. Further epidemiologic studies of this disease are
necessary as it is clear that it exists in our population. At that moment we
were unable to do typization.
Foramina parietalia permagna: Case report
Authors: Nikolic Slobodan , Zivkovic Vladimir , Strajina Veljko
Published: November 2012

Introduction. In forensic autopsy, pathologists are not particularly
interested in the anatomical morphological variations of the skull bones,
especially if those variations are not very frequent. Foramina parietalia
permagna are developmental benign anomalies resulting from large ossification
defects of the parietal bone. Case Outline. Herein was presented a case of
80-year-old female, whose autopsy revealed congenital defect of parietal
bones - enlarged parietal foramina. These defects were capped by a fibrous
membrane and covered by normal scalp. This condition was completely
asymptomatic. Despite the fact that the deceased was very old, the giant
parietal foramina were recognized. Conclusion. The forensic pathologist must
know how to recognize morphological variations of the skull bones, such as
foramina parietalia permagna despite their rare occurrence. This benign
anomaly could be associated with anomalies of cerebral venous development and
cortical infolding, or asymptomatic as in the presented case. This anomaly of
parietal bones could be a useful tool in the identification of forensic
cases.
Posthysterectomy vault prolapse of vaginal walls: Choice of operating procedure
Authors: Argirovic Rajka
Published: November 2012

Post-hysterectomy vaginal vault prolapse is a common complication following
different types of hysterectomy with a negative impact on the woman?s quality
of life due to associated urinary, anorectal and sexual dysfunction. A clear
understanding of the supporting mechanisms for the uterus and vagina is
important in order to make the right choice of the corrective procedure and
also to minimize the risk of posthysterectomy occurrence of vault prolapse.
Preexisting pelvic floor defect prior to hysterectomy is the single most
important risk factor for vault prolapse. Various surgical techniques have
been advanced in hysterectomy to prevent vault prolapse. Vaginal vault repair
can be carried out abdominally or vaginally. Sacrospinous fixation and
abdominal sacrocolpopexy are the commonly performed procedures. The vaginal
approach for vault prolapse is superior to the abdominal approach in terms of
complication rates, blood loss, postoperative discomfort, length of hospital
stay and costeffectiveness. Moreover, it allows the simultaneous repair of
all coexistent pelvic floor defects, such as cystocele, enterocele and
rectocele. Abdominal sacrocolpopexy is associated with a lower rate of
recurrent vault prolapse and dyspareunia than the vaginal sacrospinous
colpopexy. Other less commonly performed procedures include uterosacral
ligament suspension and illeococcygeal fixation with a high risk of ureteric
injury. Surgical mesh of non-absorbent material is gaining in popularity and
preliminary data from vaginal mesh procedures is encouraging.
Eating disorders

Published: November 2012

Eating disorders are considered chronic diseases of civilization. The most
studied and well known are anorexia and bulimia nervosa. Anorexia is
considered one of the most common psychiatric problems of girls in puberty
and adolescence. Due to high mortality and morbidity as well as the
increasing expansion of these diseases, it is clear why the amount of
research on these diseases is growing worldwide. Eating disorders lead to
numerous medical complications, mostly due to late diagnosis. The main
characteristic of these diseases is changed behavior in the nutrition, either
as an intentional restriction of food, i.e. extreme dieting, or overeating,
i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting,
excessive exercise, and misuse of laxatives and diuretics for the purpose of
maintaining or reducing body weight are characteristic forms of compensatory
behavior of patients with eating disorder. The most appropriate course of
treatment is determined by evaluating the patient?s health condition,
associated with behavior and eating habits, the experience of one?s own body,
character traits of personality, and consequently the development and
functioning of the individual. The final treatment plan is individual. Eating
disorders are a growing medical problem even in this part of the world.
Prevention should be planned in cooperation with different sectors so as to
stop the epidemic of these diseases.
Accuracy of prediction of birth weight by fetal ultrasound
Authors: Bajracharya J , Shrestha NS , Karki C
Published: November 2012

Introduction: Estimation of accurate fetal weight is essential in obstetrical management and we aim to see the accuracy of fetal ultrasound in estimating birth weight in our setting. Method: 150 women with full term singleton pregnancy leading to live birth were included in the study. Prenatal fetal ultrasound database was reviewed for the fetal biometry and fetal weight estimation and delivery records were reviewed for actual birth weight. Error in estimation was calculated.Result: The study showed that fetal ultrasound using Hadlock.s formula has error in estimation of fetal weight by about 290 gm ± 250 gm. In 40% of the cases, there is an error of estimation by more than 10% compared to actual weight. Conclusion: There is a significant error in the estimation of the fetal weight. Depending only on the fetal ultrasound for the estimation of fetal weight can lead to unnecessary obstetrical intervention. It is necessary to correlate the ultrasound findings with clinical examination.Health Renaissance; September-December 2012; Vol 10 (No.3);236-238DOI: http://dx.doi.org/10.3126/hren.v10i3.7053

Published: November 2012

Idiopathic thrombocytopenia (ITP) is an autoimmune disorder characterized by a reduced platelet count with otherwise normal blood cell counts. Autoimmune thyroid disease is not considered a cause of thrombocytopenia. We report a case of autoimmune thrombocytopenic purpura associated with hyperthyroidism in which the patient's thrombocytopenia and thyrotoxicosis resolved concomitantly. We recommend testing for hyperthyroidism in all patients with unexplained thrombocytopenia and that family members of patients be evaluated, screened, and observed for thrombocytopenia and hyperthyroidism.

Painting the Painter
Authors: Leroy Fabrice
Published: November 2012

French cartoonist and filmmaker Joann Sfar has often used the comics medium to reflect on visual representation. His latest bande dessinée, Chagall en Russie ['Chagall in Russia'] (2010-2011), continues some of the meta-pictural elements previously found in his Pascin (2000-2002), which already featured Chagall in several episodes, as well as his acclaimed series, The Rabbi's Cat, where Sfar introduced the character of an anonymous Russian painter, whose biography and artistic stance seemingly referred to that of Marc Chagall. Although Chagall en Russie explicitly refers to the real-life Franco-Russian modernist painter, it is certainly not a standard biographical exercise. By offering a synthetic and often symbolic version of personal and historical events experienced by Chagall, Sfar takes certain liberties with the painter's life story as it was outlined by the artist (in My Life, his 1922 autobiography) and by many biographers and art historians. Sfar does not seek an authentic depiction of his subject's verifiable life journey, but rather views it through a metaphorical narrative, which is itself inspired by Chagall's artistic universe and raises questions about the figurative possibilities of comics.
Duration in Comics
Authors: Conard Sébastien , Lambeens Tom
Published: November 2012

For Saint Augustine, time was a distentio animi, an extension of the mind. This opinion strongly differs from our modern understanding of time as a measurable parameter of the physical world. Nonetheless, subjectifying approaches still coexist alongside objectifying conceptions of time. They necessarily alternate in our daily lives: though we all keep years, seasons and hours in mind, we live through many moments very personally. Hence, it is indispensable that we pay attention to subjective time experience in the humanities and the arts. In this article, we introduce the concept of duration, as developed by Bergson and Deleuze, into the field of comics studies. We analyse the creation of an experience of time in the work of Chris Ware and Kevin Huizenga, focusing particularly on their deployment of repetition, but we also note how artists such as André Franquin and Willy Vandersteen transgressed classical reading time by invoking a feeling of duration. We go on to consider abstract comics, and the concrete awareness of the actual moment they offer to the reader, which generates direct experience of duration. However, taking Martin Vaughn-James' The Cage as an example, we point out that such a temporal sensation is not dependent on formal abstraction but can occur within the boundaries of pictorial figuration.

Building a Policy-Oriented Research Partnership for Knowledge Mobilization and Knowledge Transfer: The Case of the Canadian Metropolis Project
Authors: Shields John , Evans Bryan
Published: November 2012

The aim of this paper is to examine government–university–community partnerships for knowledge mobilization (KM) and knowledge transfer (KT) in the area of immigration and settlement research using the illustrative case of the Canadian Metropolis Project. The Metropolis Project in Canada began in 1995 with the goal of enhancing policy-oriented research capacity for immigration and settlement and developing ways to better use this research in government decision-making. Core funding for this partnership was provided jointly by Citizenship Immigration Canada (CIC), a department of the Government of Canada and the primary social science granting agency, the Social Science and Humanities Research Council (SSHRC). As of 2012, and subsequent to three successful funding phases, the decision was made to end government and SSHRC core funding for this initiative, however, other non-governmental funding avenues are being explored. The longevity of this partnership and the conclusion of this specific initiative present an opportunity to reflect critically on the nature of such partnerships. This paper is an attempt to identify some of the key themes, issues and challenges related to research partnerships, KM and KT. Also, with the aid of an illustrative case, it aims to specify some of the possibilities and limitations of this kind of policy relevant knowledge mobilization. Special consideration will be placed on the context in which the demand for knowledge mobilization and knowledge transfer has emerged. This examination has considerable international relevance as the Canadian Metropolis Project offers the leading example of a research partnership in the field of immigration and settlement.
Cholesterol-Dependent Energy Transfer between Fluorescent Proteins—Insights into Protein Proximity of APP and BACE1 in Different Membranes in Niemann-Pick Type C Disease Cells
Authors: Von Einem Bjoern , Weber Petra , Wagner Michael , Malnar Martina , Kosicek Marko , Hecimovic Silva , VonArnim Christine , Schneckenburger Herbert
Published: November 2012

Förster resonance energy transfer (FRET) -based techniques have recently been applied to study the interactions between β-site APP-cleaving enzyme-GFP (BACE1-GFP) and amyloid precursor protein-mRFP (APP-mRFP) in U373 glioblastoma cells. In this context, the role of APP-BACE1 proximity in Alzheimer’s disease (AD) pathogenesis has been discussed. FRET was found to depend on intracellular cholesterol levels and associated alterations in membrane stiffness. Here, NPC1 null cells (CHO-NPC1−/−), exhibiting increased cholesterol levels and disturbed cholesterol transport similar to that observed in Niemann-Pick type C disease (NPC), were used to analyze the influence of altered cholesterol levels on APP-BACE1 proximity. Fluorescence lifetime measurements of whole CHO-wild type (WT) and CHO-NPC1−/− cells (EPI-illumination microscopy), as well as their plasma membranes (total internal reflection fluorescence microscopy, TIRFM), were performed. Additionally, generalized polarization (GP) measurements of CHO-WT and CHO-NPC1−/− cells incubated with the fluorescence marker laurdan were performed to determine membrane stiffness of plasma- and intracellular-membranes. CHO-NPC1−/− cells showed higher membrane stiffness at intracellular- but not plasma-membranes, equivalent to cholesterol accumulation in late endosomes/lysosomes. Along with higher membrane stiffness, the FRET efficiency between BACE1-GFP and APP-mRFP was reduced at intracellular membranes, but not within the plasma membrane of CHO-NPC1−/−. Our data show that FRET combined with TIRF is a powerful technique to determine protein proximity and membrane fluidity in cellular models of neurodegenerative diseases.
Information and Energy/Matter
Authors: Dodig Crnkovic Gordana
Published: November 2012

What can we hope for from studies of information related to energy/matter (as it appears for us in space/time)? Information is a concept known for its ambiguity in both common, everyday use and in its specific technical applications throughout different fields of research and technology. However, most people are unaware that matter/energy today is also a concept surrounded by a disquieting uncertainty. What for Democritus were building blocks of the whole universe appear today to constitute only 4% of its observed content. (NASA 2012) [1] The rest is labeled “dark matter” (conjectured to explain gravitational effects otherwise unaccounted for) and “dark energy” (introduced to account for the expansion of the universe). We do not know what “dark matter” and “dark energy” actually are. This indicates that our present understanding of the structure of the physical world needs re-examination. [...]
Aligning the Economic Value of Companion Diagnostics and Stratified Medicines
Authors: Blair Edward D. , Stratton Elyse K. , Kaufmann Martina
Published: November 2012

The twin forces of payors seeking fair pricing and the rising costs of developing new medicines has driven a closer relationship between pharmaceutical companies and diagnostics companies, because stratified medicines, guided by companion diagnostics, offer better commercial, as well as clinical, outcomes. Stratified medicines have created clinical success and provided rapid product approvals, particularly in oncology, and indeed have changed the dynamic between drug and diagnostic developers. The commercial payback for such partnerships offered by stratified medicines has been less well articulated, but this has shifted as the benefits in risk management, pricing and value creation for all stakeholders become clearer. In this larger healthcare setting, stratified medicine provides both physicians and patients with greater insight on the disease and provides rationale for providers to understand cost-effectiveness of treatment. This article considers how the economic value of stratified medicine relationships can be recognized and translated into better outcomes for all healthcare stakeholders.
First Principles Study on Electronic Structure and Optical Properties of Ternary GaAs:Bi Alloy
Authors: Yu Lifei , Li Dechun , Zhao Shengzhi , Li Guiqiu , Yang Kejian
Published: November 2012

The electronic structure and optical properties of ternary GaAs:Bi alloy are investigated by first principles calculations. It is found that the band gap of GaAs1-xBix decreases monotonously with the increasing of Bi concentration, resulting in the fundamental absorption edge and main absorption peaks of GaAs1-xBix shifting toward lower energy with the increase of the Bi content. The optical constants of GaAs1-xBix, such as the optical absorption coefficient, refractive index, extinction coefficient and optical conductivity, are greater than those of pure GaAs when x > 3.1%, but less than those of pure GaAs when x < 3.1%, which is primarily decided by the intraband level repulsions between Bi-induced states and host states on the valence bands; the contribution of Bi-6s, Bi-6p orbitals and Ga-4p, Ga-4s orbitals on conduction bands is also crucial. Bi doping plays an important role in the modulation of the static dielectric constant and the static refractive index. These results suggest a promising application of GaAs1-xBix alloy as a semiconductor saturable absorber.

Published: November 2012

Deltamethrin, a member of the pyrethroids, one of the safest classes of pesticides, is among some of the most popular and widely used insecticides in the World. Our objective was to synthesize an oxabicyclolactone 6 and five novel pyrethroids 8–12 from readily available furfural and D-mannitol, respectively, and evaluate their biological activity against four insect species of economic importance namely A. obtectus, S. zeamais, A. monuste orseis, and P. americana. A concise and novel synthesis of 6,6-dimethyl-3-oxabicyclo[3.1.0]hexan-2-one (6) from furfural is described. Photochemical addition of isopropyl alcohol to furan-2(5H)-one afforded 4-(1'-hydroxy-1'-methylethyl)tetrahydro-furan-2-one (3). The alcohol 3 was directly converted into 4-(1'-bromo-1'-methylethyl)-tetrahydrofuran-2-one (5) in 50% yield by reaction with PBr3 and SiO2. The final step was performed by cyclization of 5 with potassium tert-butoxide in 40% yield. The novel pyrethroids 8–12 were prepared from methyl (1S,3S)-3-formyl-2,2-dimethylcyclopropane-1-carboxylate (7a) by reaction with five different aromatic phosphorous ylides. Compounds 6–12 presented high insecticidal activity, with 6 and 11 being the most active. Compound 6 killed 90% of S. zeamais and 100% of all the other insects evaluated. Compound 11 killed 100% of all insects tested.

Authors: Buddenbaum Henning , Stern Oksana , Stellmes Marion , Stoffels Johannes , Pueschel Pyare , Hill Joachim , Werner Willy
Published: November 2012

In order to monitor dryness stress under controlled conditions, we set up an experiment with beech seedlings in plant pots and built a platform for observing the seedlings with field imaging spectroscopy. This serves as a preparation for multi-temporal hyperspectral air- and space-borne data expected to be available in coming years. Half of the trees were watered throughout the year; the other half were cut off from water supply for a five-week period in late summer. Plant health and soil, as well as leaf water status, were monitored. Moreover, hyperspectral images of the trees were acquired four times during the experiment. Results show that the experimental imaging setup is well suited for recording hyperspectral images of objects, like the beech pots, under natural illumination conditions. The high spatial resolution makes it feasible to discern between background, soil, wood, green leaves and brown leaves. Furthermore, it could be shown that dryness stress is detectable from an early stage even in the limited spectral range considered. The decline of leaf chlorophyll over time was also well monitored using imaging spectroscopy data.
Multivariate and Multiscale Data Assimilation in Terrestrial Systems: A Review
Authors: Montzka Carsten , Pauwels Valentijn , Franssen Harrie-Jan , Han Xujun , Vereecken Harry
Published: November 2012

More and more terrestrial observational networks are being established to monitor climatic, hydrological and land-use changes in different regions of the World. In these networks, time series of states and fluxes are recorded in an automated manner, often with a high temporal resolution. These data are important for the understanding of water, energy, and/or matter fluxes, as well as their biological and physical drivers and interactions with and within the terrestrial system. Similarly, the number and accuracy of variables, which can be observed by spaceborne sensors, are increasing. Data assimilation (DA) methods utilize these observations in terrestrial models in order to increase process knowledge as well as to improve forecasts for the system being studied. The widely implemented automation in observing environmental states and fluxes makes an operational computation more and more feasible, and it opens the perspective of short-time forecasts of the state of terrestrial systems. In this paper, we review the state of the art with respect to DA focusing on the joint assimilation of observational data precedents from different spatial scales and different data types. An introduction is given to different DA methods, such as the Ensemble Kalman Filter (EnKF), Particle Filter (PF) and variational methods (3/4D-VAR). In this review, we distinguish between four major DA approaches: (1) univariate single-scale DA (UVSS), which is the approach used in the majority of published DA applications, (2) univariate multiscale DA (UVMS) referring to a methodology which acknowledges that at least some of the assimilated data are measured at a different scale than the computational grid scale, (3) multivariate single-scale DA (MVSS) dealing with the assimilation of at least two different data types, and (4) combined multivariate multiscale DA (MVMS). Finally, we conclude with a discussion on the advantages and disadvantages of the assimilation of multiple data types in a simulation model. Existing approaches can be used to simultaneously update several model states and model parameters if applicable. In other words, the basic principles for multivariate data assimilation are already available. We argue that a better understanding of the measurement errors for different observation types, improved estimates of observation bias and improved multiscale assimilation methods for data which scale nonlinearly is important to properly weight them in multiscale multivariate data assimilation. In this context, improved cross-validation of different data types, and increased ground truth verification of remote sensing products are required.
A DO- and pH-Based Early Warning System of Nitrification Inhibition for Biological Nitrogen Removal Processes
Authors: Hong Seil , Choi Il , Lim Byung , Kim Hyunook
Published: November 2012

In Korea, more than 80% of municipal wastewater treatment plants (WWTPs) with capacities of 500 m3·d−1 or more are capable of removing nitrogen from wastewater through biological nitrification and denitrification processes. Normally, these biological processes show excellent performance, but if a toxic chemical is present in the influent to a WWTP, the biological processes (especially, the nitrification process) may be affected and fail to function normally; nitrifying bacteria are known very vulnerable to toxic substances. Then, the toxic compound as well as the nitrogen in wastewater may be discharged into a receiving water body without any proper treatment. Moreover, it may take significant time for the process to return back its normal state. In this study, a DO- and pH-based strategy to identify potential nitrification inhibition was developed to detect early the inflow of toxic compounds to a biological nitrogen removal process. This strategy utilizes significant changes observed in the oxygen uptake rate and the pH profiles of the mixed liquor when the activity of nitrifying bacteria is inhibited. Using the strategy, the toxicity from test wastewater with 2.5 mg·L−1 Hg2+, 0.5 mg·L−1 allythiourea, or 0.25 mg·L−1 chloroform could be successfully detected.
Measuring the Economic Impact of Migration-Induced Tourism
Authors: Forsyth Peter , Dwyer Larry , Seetaram Neelu , King Brian
Published: November 2012

Migration induces inbound and outbound tourism flows for a country heavily reliant on migration, such as Australia. Previous research has provided estimates for Australia of the effects of changes in migration on the volume of inbound and outbound tourism. When supplemented with information
about tourist spending, estimates can be made of any expenditure changes associated with migration-induced tourism. Such migration-induced tourism expenditures will have economic impacts on the economy. This study estimates the economic impacts of migration-induced inbound and outbound tourism
flows using a computable general equilibrium (CGE) model for Australia projecting the effects on key economic variables such as real GDP, real value added, economic welfare, and employment.
Second-Home Ownership and Place Attachment: Drivers of Visitation, Word-of-Mouth Promotion, and Hosting
Authors: McLeod Brumby , Busser James A.
Published: November 2012

This study examined the role of nonresident home owners in Costa Rica using a theoretical model based on a two-dimensional construct of place attachment. Place identity and place dependence were examined as drivers of visitation, word-of-mouth promotion, and hosting. The findings of this study support a two-dimensional place attachment construct and suggest that the place identity dimension is the primary driver of visitation and word-of-mouth promotion among current nonresident home owners. The study also revealed diminishing word-of-mouth promotion as visitation increased. The study introduces a new construct, hosting, and examines the role of visitation and word-of-mouth promotion on hosting visiting friends and relatives. The results and discussion provide important theoretical and managerial implications for tourism.
Organizational-Level RFID Technology Adoption in the Hospitality Industry

Published: November 2012

The purpose of this study was to explore the influence of technological, organizational, and environmental factors on the hospitality operators' adoption of radio frequency identification (RFID) technology. Based on a sample of 125 technology decision makers at major hospitality corporations in the US, the results of the study indicated that except stakeholder pressure, all of the technological, organizational, and environmental factors had significant impact on hospitality operators' intention to adopt RFID technology. By identifying the factors affecting hospitality operators' RFID technology adoption decisions, technology vendors could design appropriate marketing strategies to reach potential adopters and they could educate these adopters better on the benefits of RFID technologies in order to increase the usage of these technologies in the hospitality industry.
Eilat Syndrome: Deviant Behavior Among Temporary Hotel Workers
Authors: Belhassen Yaniv
Published: November 2012

Based on primary and secondary data, it is argued that the unique characteristics of Eilat as a remote resort town situated on the historical and cultural margins of Israeli society combine to produce a liminal image that attracts hotel employees prone to substance abuse during what
they view as a temporary sojourn in the city. In addition, this liminal image presumably shapes the perception of these temporary employees regarding their sojourn in the town on a transitional job during the period of time between their national/military service and civilian life. This article
delineates the sociocultural, organizational, and legal conditions leading to the occurrence of this behavioral syndrome.

Résumé La performance s’impose-t-elle comme une notion exogène à l’intervention sociale ou s’inscrit-elle dans la continuité de son évolution socio-historique ? si elle s’inscrit dans l’histoire de l’intervention sociale, ne doit-on pas envisager qu’elle puisse en être un vecteur de développement ? à quelles conditions ? L’article s’attache à montrer, à partir d’une contextualisation socio-historique, que les organisations de l’intervention sociale devraient, pour ce faire, être en mesure de pallier les défauts issus de « l’idéologique gestionnaire » sur laquelle s’appuie pour l’instant principalement l’introduction de la performance.
Les sentiers de la performance
Authors: Portets Noëlle
Published: November 2012

Résumé Si la performance est superlative, elle porte en elle un rapport au temps spécifique, visant efficacité et synchronisation des comportements. Comment penser le(s) temps d’expériences singulières ? La performance est performative : en disant, elle accomplit. De quels mots parlons-nous le travail social ? Jusqu’où courir se demande E. Zatopek, inventeur du sprint final. Tendre vers le moment où, c’est aussi ce que recherchent les personnes qu’accompagnent les travailleurs sociaux : un travail d’évaluation vise là à trouver son arrangement propre, au milieu des autres. Tenir le modèle adaptatif, c’est risquer de nous perdre. Comment alors penser ensemble l’ éco nomique et une «  éco logie du lien social » ?
La performance pour les organisations médico-sociales : évoluer sans se dévoyer
Authors: Samr Mustapha
Published: November 2012

Résumé La performance est avant tout un concept à décaler de la culture du chiffre, du quantifiable. Aujourd’hui, se repérer dans le champ du secteur médico-social peut être déjà en soi une performance. Dans une société se voulant inclusive, les besoins des usagers sont-ils totalement respectés ? Le nouveau paradigme de la performance, associé essentiellement aux aspects comptables et organisationnels, fait vaciller le fait associatif et ses valeurs fondatrices. La définition de la santé retenue par l’ oms ne fait référence à aucune mesure parce qu’aucune mesure, ni plusieurs ne peuvent déterminer une fois pour toutes l’état de bien-être d’un individu, donc sa santé.
Handicap : l'inclusion comme performance
Authors: Grimaud Lin
Published: November 2012

Résumé L’implication de la société globale à l’égard de la personne handicapée obéit aujourd’hui à ce qu’on appelle la politique de l’inclusion. Ce principe induit une confrontation effective qui, si elle repose bien sur une intention éthiquement et politiquement correcte, n’en constitue pas moins une épreuve pour les parties en présence : l’usager, sa famille, les aidants professionnels, les acteurs de la société ordinaire. Car de fait, un système de représentations sociales implicites tend à contrarier la mise en œuvre de l’inclusion. Avec quelles théories comprendre la nature de ces entraves qui font bien souvent du processus d’inclusion de la personne handicapée un parcours du combattant et une véritable performance ?
L'injonction de gagner, la grâce de perdre
Authors: Buoro Vincent
Published: November 2012

Résumé Souvent remplis de doutes sur leurs capacités, les étudiants en travail social font l’expérience du non-sens durant leur formation, tiraillés entre la précision de leur désir et la découverte d’attendus tout aussi précis mais pour autant éloignés de ce qui les fait entrer en formation. Là, dans ce rapport entre souffrance et désir, s’immisce sans détour ni prévention une distinction entre formation et diplôme. Quand leurs mots traduisent une joie lors des résultats, les nôtres résonnent ailleurs, certes remplis du plaisir de les voir en réussite, mais également avec l’espoir que quelque chose a lâché du côté du résultat réel. Où se situe la notion de performance ? Dans le fait de réussir, de produire es compétences, ou dans celui de rendre possible un indécision ? Accompagner un étudiant prend alors sens dans cette dialectique qui s’ouvre entre la quête du diplôme et la souffrance pour l’atteindre. Le reste ne se maîtrise pas, il est le fruit de la rencontre et de l’accompagnement, lueur d’une performance qui se démarque de sa définition intrinsèque.
Faire de la performance un atout
Authors: Viollet Patrick
Published: November 2012

Résumé Quelle que soit l’approche de la performance, elle est indissociable de la notion de résultats. et aujourd’hui, dans le domaine professionnel, l’approche des résultats est de plus en plus dépendante de celle de la compétence. Si risque il y a, dans laquelle de ces trois faces de la même problématique réside-t-il ? Dans la trilogie performance, résultat et compétence, nous avons choisi d’entrer par la compétence ; et, pour garder la maîtrise de sa mesure et de son interprétation, de construire une grille pluriprofessionnelle permettant de l’analyser et de l’évaluer.
Le stigmate : une « seconde maladie » ?
Authors: Lacaze Lionel
Published: November 2012

Résumé La lutte anti-stigmate dans le secteur des maladies mentales suppose la reconnaissance que le stigmate est une « seconde maladie », non vue et occultée. Elle a sa source dans les préjugés, les conceptions erronées à l’égard des troubles mentaux, les conséquences négatives des traitements et la qualité de vie péjorative des personnes qui en sont affectées. La notion de stigmate est analysée à travers ses diverses composantes, dans la perspective de soutenir cette lutte, considérée par l’ oms comme une cause fondamentale.

Peer Coaching to Support Writing Development
Authors: Peinhardt Rebecca D. , Hagler Debra
Published: November 2012

Learning to write well is a difficult but worthwhile effort, as nurses often need to communicate effectively through writing. A range of interventions has been used to promote effective writing by nursing students, but little outcome evidence, beyond student and faculty satisfaction, has been reported. A peer coaching assignment in a senior-level RN-to-BSN nursing complex care theory course required students to complete a scaffolded review of a peer’s draft paper and provide constructive feedback to the peer. A masked and a nonmasked faculty rater (with interrater reliability of >0.99) scored the drafts and final papers. The mean scores of the participants’ papers improved dramatically (

Repulsion forces of superplasticizers on ground granulated blast furnace slag in alkaline media, from AFM measurements to rheological properties

The electrostatic and steric repulsion induced by different superplasticizers on ground granulated blast furnace slag in alkaline media have been studied. The superplasticizers were sulfonated naphthalene, sulfonated melamine, vinyl copolymer, and polycarboxylate- based admixtures. With these superplasticizers the slag suspensions had negative zeta potentials, ranging from -3 to -10 mV. For the first time the adsorbed layer thicknesses for superplasticizers on slag using colloidal probe atomic force microscopy has been measured. To model the interparticle force interactions an effective Hamaker constant was computed from dielectric properties measured on a dense slag sample produced by spark plasma sintering. The obtained results conclude that the dispersion mechanism for all the superplasticizers studied in the present work is mainly dominated by the steric repulsion. Results were then used in a yield stress model, YODEL, to predict the yield stress with and without the superplasticizers. Predictions of the yield stress agreed well with experimental results.
High-temperature performance of mortars and concretes based on alkali-activated slag/metakaolin blends
Authors: Bernal S. A. , Mejía de Gutiérrez R. , Ruiz F. , Quiñones H. , Provis J. L.
Published: November 2012

This paper assesses the performance of mortars and concretes based on alkali activated granulated blastfurnace slag (GBFS)/metakaolin (MK) blends when exposed to high temperatures. High stability of mortars with contents of MK up to 60 wt.% when exposed to 600 °C is identified, with residual strengths of 20 MPa following exposure to this temperature. On the other hand, exposure to higher temperatures leads to cracking of the concretes, as a consequence of the high shrinkage of the binder matrix and the restraining effects of the aggregate, especially in those specimens with binders containing high MK content. A significant difference is identified between the water absorption properties of mortars and concretes, and this is able to be correlated with divergences in their performance after exposure to high temperatures. This indicates that the performance at high temperatures of alkali-activated mortars is not completely transferable to concrete, because the systems differ in permeability. The differences in the thermal expansion coefficients between the binder matrix and the coarse aggregates contribute to the macrocracking of the material, and the consequent reduction of mechanical properties.

Authors: Mercader Mª P. , Olivares M. , Ramírez de Arellano A.
Published: November 2012

The research conducted in this paper focuses on the generation of a model for the quantification of energy consumption in building. This is to be done through one of the most relevant environmental impact indicators associated with weight per m2 of construction, as well as the energy consumption resulting from the manufacturing process of materials used in building construction.

The practical application of the proposed model on different buildings typologies in Seville, will provide information regarding the building materials, the subsystems and the most relevant construction elements. Hence, we will be able to observe the impact the built surface has on the environment.

The results obtained aim to reference the scientific community, providing quantitative data comparable to other types of buildings and geographical areas. Furthermore, it may also allow the analysis and the characterization of feasible solutions to reduce the environmental impact generated by the different materials, subsystems and construction elements commonly used in the different building types defined in this study.
