Analytic Tools for Evaluating Variability of Standard Errors in Large-Scale Establishment Surveys
Authors: Cho MoonJung , Eltinge John L. , Gershunskaya Julie , Huff Larry 
Published: December 2014

Abstract
Large-scale establishment surveys often exhibit substantial temporal or cross-sectional variability in their published standard errors. This article uses a framework defined by survey generalized variance functions to develop three sets of analytic tools for the evaluation of these patterns of variability. These tools are for (1) identification of predictor variables that explain some of the observed temporal and cross-sectional variability in published standard errors; (2) evaluation of the proportion of variability attributable to the abovementioned predictors, equation error and estimation error, respectively; and (3) comparison of equation error variances across groups defined by observable predictor variables. The primary ideas are motivated and illustrated by an application to the U.S. Current Employment Statistics program.
Data Smearing: An Approach to Disclosure Limitation for Tabular Data
Authors: Toth Daniell 
Published: December 2014

Abstract
Statistical agencies often collect sensitive data for release to the public at aggregated levels in the form of tables. To protect confidential data, some cells are suppressed in the publicly released data. One problem with this method is that many cells of interest must be suppressed in order to protect a much smaller number of sensitive cells. Another problem is that the covariates used to aggregate and level of aggregation must be fixed before the data is released. Both of these restrictions can severely limit the utility of the data. We propose a new disclosure limitation method that replaces the full set of microdata with synthetic data for use in producing released data in tabular form. This synthetic data set is obtained by replacing each unit’s values with a weighted average of sampled values from the surrounding area. The synthetic data is produced in a way to give asymptotically unbiased estimates for aggregate cells as the number of units in the cell increases. The method is applied to the U.S. Bureau of Labor Statistics Quarterly Census of Employment and Wages data, which is released to the public quarterly in tabular form and aggregated across varying scales of time, area, and economic sector.
Genetically identical co-housed pigs as models for dietary studies of gut microbiomes

Published: December 2014

AbstractThe impact of diet on the microbial composition in the gastrointestinal tract (GIT) has been well documented. However, quantifying the role of the diet in shaping microbial composition in humans has been difficult due to the influence of host genetics and the environment. To test the influence of diets on the GIT microbiome independently of host genotype and environment, two genetically identical co-housed pigs were used in an A-B-A-B design across four 14-day periods using two distinct diets that differed in dietary fiber source, soybean hulls or wheat bran. Shifts in fecal microbiomes were assessed with respect to dietary changes by 454-pyrosequencing analysis using the V3 region of the 16S rRNA genes. Similarity analysis revealed that the GIT microbiome distinctly clustered by diets rather than by individual. Diversity analysis showed that the diet fed had an influence on GIT microbiome diversity, which was host specific. While many bacterial taxa and KEGG orthologs reacted similarly to switches in diet, some bacterial taxa and KEGG orthologs reacted differentially in each of the pigs. While diet changed the GIT microbiome composition of isogenic co-housed pigs, inter-individual variations from epigenetics were not entirely eliminated by the use of cloned pigs.

Published: December 2014

Abstract
Utilization of agricultural waste material with approach to enhance the heavy metal remediation properties by carbonizing the biomass at nano size particles has been explored in present investigation from aqueous solutions. In this study the lignocellulosic, nitrogenous agricultural waste biomass Delbergia sissoo pods (DSP) has been tried for sequestering of Cd (II), Pb (II) and Ni (II) metal ions from aqueous solutions. Batch experiments were performed for removal of targeted metal ions keeping in consideration the preliminary affecting parameters such as effect of adsorption dose, pH, initial metal ion concentration, stirring speed and contact time. The sorption studies were analyzed by using, Freundlic isotherm and Langmuir isotherm models. The kinetics of the process was evaluated by pseudo pseudo-first order and pseudo second order kinetic models. Studies reveal that the equilibrium was achieved with in 30 min of the contact time at optimized parameters. Analytical studies of biosorbent were done by means of FT-IR, SEM and XRD. Desorption experiments were carried out using HCl solution with a view to regenerate the spent adsorbent and to recover the adsorbed metal ions.
Modification of Salix americana willow bark for removal of heavy metal ions from aqueous solutions
Authors: Rypińska Iwona , Biegańska Marta 
Published: December 2014

Abstract
Salix americana willow bark is a waste arising in the process of wicker decortication that so far has not found any practical application. The bark can adsorb metal ions, because in its composition among others are phenolic groups which may be involved in the removal of metal ions from water solutions. The results of sorption of copper(II) and zinc(II) on modified willow bark of Salix americana were presented. The bark was modified with nitric and sulfuric acids at concentrations ranging from 5 to 15%. The best adsorption results were obtained using 15% nitric acid for modification. Adsorption of metal ions from aqueous solutions at concentrations raging from 20 to 100 mg/dm3 was studied. It was found that an increase in the initial concentration of copper(II) and zinc(II) resulted in an increase in their adsorption on the modified cortex.
Time requirements in closed and open batch distillation arrangements for separation of a binary mixture
Authors: Zhao Shuo , Bai Peng , Guo Xianghai , Tang Ke , Li Guangzhong 
Published: December 2014

Abstract
Batch time requirements are provided for the separation of binary zeotropic mixtures in two different multivessel columns (with and without vapor bypass), a non-cyclic two-vessel column and a regular batch column based on dynamic simulations. The first three columns are operated as closed (total reflux) systems and the regular batch column is operated as an open (partial reflux) system. We analyze the effects of feed composition, relative volatility and product specification on the time requirements. The multivessel arrangements perform better than the regular batch column, which requires from 4.00 to 34.67% more time to complete a given separation. The elimination of the vapor bypass in the multivessel column is impractical though it has a positive effect on the batch time requirements. Thus, the multivessel column, with the vapor stream bypassing the intermediate vessel, is proposed as the best candidate for a binary zeotropic mixture with low concentration of light component, low relative volatility and high product purity demand. Furthermore, an experimental multivessel column with vapor bypass is built and the corresponding experiments verify the simulations.
A digital photography protocol for the rapid assessment of herbaceous communities in riparian buffers
Authors: Bonin Laurianne , Proulx Raphaël , Rheault Guillaume 
Published: December 2014

AbstractClose-range digital photography is a promising tool for monitoring plant communities, yet this technology has not been used to indicate changes to the compositional and functional characteristics of riparian vegetation buffers in agro-ecosystems. We tested a photographic protocol using image indices to monitor differences in the compositional (species diversity) and functional characteristics (plant height, flowering and leaf traits) of 28 herbaceous communities repeatedly surveyed over an entire growing season. Specifically, we used known vegetation properties to predict image texture and geometric patterns. Our results revealed that image texture decreased with increasing plant height, leaf polyphenol content and species diversity. Low texture values in close-range digital images were typically found in tall, flowering, and functionally diversified assemblages consisting mostly of forbs species. In contrast, species assemblages dominated by grasses or sedges presented more random geometric patterns and images with higher texture values. Further tests of this photographic protocol will have to explore other image indices and extend its application to other ecosystems.

Published: December 2014

Abstract
Determinant formulas for special binary circulant matrices are derived and a new open problemregarding the possible determinant values of these specific circulant matrices is stated. The ideas used forthe proofs can be utilized to obtain more determinant formulas for other binary circulant matrices, too. Thesuperiority of the proposed approach over the standard method for calculating the determinant of a generalcirculant matrix is demonstrated.

Balance Training Using an iPhone Application in People With Familial Dysautonomia: Three Case Reports
Authors: Gefen Rosalee , Dunsky Ayelet , Hutzler Yeshayahu 
Published: December 2014

Background and PurposeFamilial dysautonomia (FD) is a rare genetic autosomal recessive disease that impairs vital functions and causes neural and motor deficiency. These motor deficits often are characterized by static and dynamic instability and an ataxic gait. As a result, people with FD are at risk for significant physical impairment and falls and pose unique challenges for delivering rehabilitation exercise. Consequently, there is a need for challenging ways to safely and feasibly deliver active exercise rehabilitation to these individuals.Case DescriptionThis case report describes 3 people with FD (ages 11, 12, and 22 years) with gait and stability problems who attended rehabilitation exercises augmented by the use of an iPhone application specifically developed for the program.OutcomesThe Berg Balance Scale and the Four Square Step Test were conducted prior to training, after training, and after 2 months of follow-up without training. Two patients showed improvements on both measures at the posttest, which were maintained throughout follow-up testing.DiscussionAlthough greater experience is needed to more fully evaluate the efficiency of the iPhone application used in this program for people with FD, the results of these initial cases are encouraging. Systematically and prospectively tracking motor abilities and other functional outcomes during rehabilitation of individuals with FD who use the suggested application in balance training is recommended in order to provide greater evidence in this area.

OBJECT
In this report, the authors review complications related to the modified prespinal route in contralateral C-7 transfer for repairing brachial plexus nerve root avulsion injury and suggest a prevention strategy.

METHODS
A retrospective, nonselected amalgamation of every case of modified contralateral C-7 transfer through the prespinal route was undertaken. The study population comprised 425 patients treated between February 2002 and August 2009. The patients were managed according to a standardized protocol by one senior professor. The surgical complications were grouped into one of the following categories: those associated with tunnel making through the prespinal route, those related to the dissection and transection of the contralateral C-7 nerve root, and those that occurred in the postoperative period.

RESULTS
The study population included 379 male and 46 female patients whose average age was 21 years (range 3 months to 56 years). A total of 401 patients were diagnosed with traumatic brachial plexus injury, the leading cause of which was motor vehicle accident, and 24 patients were diagnosed with obstetrical brachial plexus palsy. The contralateral C-7 nerve root was cut at the proximal side of the division portion of the middle trunk in 15 cases and sectioned at the distal end of the anterior and posterior divisions in 410 cases. The overall incidence of complications was 5.4% (23 of 425). Complications associated with making a prespinal tunnel occurred in 12 cases, including severe bleeding due to vertebral artery injury during the procedure in 2 cases (0.47%), temporary recurrent laryngeal nerve palsy in 5 cases (1.18%), pain and numbness in the donor upper extremity during swallowing in 4 cases (0.94%), and dyspnea caused by thrombosis of the brainstem 42 hours postoperatively in 1 case (0.24%); this last patient died 38 days after the operation. Complications related to exploration and transection of the contralateral C-7 nerve root occurred in 11 cases, including deficiency in extensor strength of the fingers and thumb in 4 cases (0.94%) due to injury to the posterior division of the lower trunk, unbearable pain on the donor upper extremity in 3 cases (0.71%), Horner's syndrome in 2 children (0.47%) who suffered birth palsy, a section of C-6 nerve root mistaken as C-7 in l case (0.24%), and atrophy of the sternocostal part of the pectoralis major in 1 case (0.24%).

CONCLUSIONS
The most serious complications of using the modified prespinal route in contralateral C-7 transfer were vertebral artery laceration and injury to the posterior division of the lower trunk. The prevention of such complications is necessary to popularize this surgical procedure and attain good long-term clinical results.

Published: December 2014

OBJECT
The object of this study was to review the effectiveness in treating severe and rigid scoliosis with posterioronly spinal release combined with derotation, translation, segmental correction, and an in situ rod-contouring technique.

METHODS
Twenty-eight patients with severe and rigid scoliosis (Cobb angle > 70° and flexibility < 30%) were retrospectively enrolled between June 2008 and June 2010. The average age of the patients was 17.1 years old (range 12–22 years old), 18 were female, and 10 were male. Etiological diagnoses were idiopathic in 24 patients, neuromuscular in 2 patients, and Marfan syndrome in 2 patients. All patients underwent posterior spinal release, derotation, translation, segmental correction, and an in situ rod-contouring technique. The scoliosis Cobb angle in the coronal plane, kyphosis Cobb angle, apex vertebral translation, and trunk shift were evaluated preoperatively and postoperatively.

RESULTS
The average operative time was 241.8 ± 32.1 minutes and estimated blood loss was 780.5 ± 132.6 ml. The average scoliosis Cobb angle in the coronal plane was corrected from 85.7° (range 77°–94°) preoperatively to 33.1° (range 21°–52°) postoperatively, with a correction ratio of 61.3%. The average kyphosis Cobb angle was 64.5° (range 59°–83°) preoperatively, which was decreased to 42.6° (range 34°–58°) postoperatively, with a correction ratio of 33.9%. After an average of 24 months of follow-up (range 13–30 months), no major complications were observed in these patients, except screw pullout of the upper thoracic vertebrae in 2 patients and screw penetration into the apical vertebrae in 1 patient.

CONCLUSIONS
Posterior spinal release combined with derotation, translation, segmental correction, and an in situ rod-contouring technique has proved to be a promising new technique for rigid scoliosis, significantly correcting the scoliosis and accompanied by fewer complications.
Surgical treatment of congenital thoracolumbar spondyloptosis in a 2-year-old child with vertebral column resection and posterior-only circumferential reconstruction of the spine column: case report
Authors: Gressot Loyola V. , Mata Javier A. , Luerssen Thomas G. , Jea Andrew 
Published: December 2014

Spondyloptosis refers to complete dislocation of a vertebral body onto another. The L5–S1 level is frequently affected. As this condition is rare, few published reports describing its clinical features and surgical outcomes exist, especially in the pediatric patient population.
The authors report the presentation, pathological findings, and radiographic studies of a 2-year-old girl who presented to Texas Children's Hospital with a history since birth of progressive spastic paraparesis. Preoperative CT and MRI showed severe spinal cord compression associated with T11–12 spondyloptosis. The patient underwent a single-stage posterior approach for complete resection of the dysplastic vertebral bodies at the apex of the spinal deformity with reconstruction and stabilization of the vertebral column using a titanium expandable cage and pedicle screws. At the 12-month follow-up, the patient remained neurologically stable without any radiographic evidence of instrumentation failure or loss of alignment.
To the best of the authors' knowledge, there have been only 2 other children with congenital thoracolumbar spondyloptosis treated with the above-described strategy. The authors describe their case and review the literature to discuss the aggregate clinical features, surgical strategies, and operative outcomes for congenital thoracolumbar spondyloptosis.

Articuler le travail auprès de parents en souffrance, avec leurs enfants et avec les professionnels qui les entourent, suppose de prendre en compte les contraintes qui s’imposent aux uns et aux autres, contraintes internes et externes. Temps discontinu des addictions, temps long de la grossesse, temps précipité de la naissance, temps de grandir, temps de guérir, temps de pensée et temps d’agir : les temporalités psychiques viennent se télescopent, s’opposent, les obligations professionnelles aussi. À ceci, déjà connu, va s’ajouter la diminution sournoise de temps imprécis, informels, d’échanges et de pensée et la contrainte d’un compte rendu et d’une culture du résultat qui vient perturber les équilibres instables mis en place.
Les conspirateurs : entre normes et temporalités
Authors: Lego Gaëlle 
Published: December 2014

Depuis plusieurs décennies, un changement radical de paradigme s’opère dans la société. L’ère semble être à la suspicion généralisée, à la course au temps, à la valorisation de l’objet-gadget, à la promotion d’un idéal de surhomme. Les moyens technoscientifiques ainsi que les réseaux informationnels déployés à la hâte emportent, avec eux, des questions à la fois éthiques, sociales et anthropologiques. Les individus d’aujourd’hui sont « disposés à agir comme s’ils ne devaient exister qu’un seul jour », disait Tocqueville. L’époque semble être à « la mélancolisation du lien social » produisant toute une cohorte de nouveaux symptômes spécifiques du nouveau discours maître de la civilisation. Ce « culte de l’urgence », valorisé comme nouveau moloch, laisse apparaître la figure d’un surmoi ravageant. La désarticulation de notre rapport au temps (intrinsèquement lié avec notre représentation de soi et de notre environnement) bouscule nos repères fondamentaux, nos pratiques de soin. Cependant, un homme a besoin d’un espace-temps stable et permanent pour se sentir vivant. À partir d’une pratique en ESAT , nous verrons comment ce temps subjectif propre à chacun est nécessaire pour qu’advienne une subjectivité.
L&#8217;avenir d&#8217;une psychanalyse&#160;: Jacques Lacan &#224; l&#8217;heure des TCC
Authors: Blesson Mathieu 
Published: December 2014

À lire ce que Jacques Lacan a pu dire ou écrire sur le devenir de la psychanalyse, il ne fait pas bon être psychanalyste aujourd’hui. Comme si la nature changeante du réel avait finalement eu raison de son optimisme. Faut-il s’en étonner ? La réponse est non. Surtout depuis que le psychanalyste est en passe de devenir une espèce en voie d’extinction. Pour le coup, la vérité d’hier est encore plus vraie aujourd’hui. L’horizon de la psychanalyse n’a jamais paru aussi bouché que lorsque la science, à la manière d’un scientisme, s’est mise à produire un discours sur le sujet aussi étouffant que séduisant. Rongés par la culpabilité, les scientifiques semblent en effet prêts à tout pour s’acheter une conduite, y compris et surtout faire preuve de responsabilité. Et quoi de mieux que la religion pour y arriver ? C’est en tout cas ce que cet article tente de démontrer, partant du principe que la psychanalyse a toujours été le symptôme révélateur d’une époque donnée et qu’à ce titre, il convient de l’interpréter pour en révéler le sens caché.
Les processus de décision dans les collectivités entre crise... de la démocratie représentative et limites du système bureaucratique
Authors: Laoukili Abdelaâli 
Published: December 2014

Cet article traite de la coopération dans le processus de décision dans les collectivités territoriales entre les élus et les cadres de l’administration. Il montre que le modèle bureaucratique sur lequel se sont construites les administrations est aujourd’hui en crise, sans que d’autres modèles plus efficaces et plus adaptés puissent le remplacer. Le modèle « managérial » issu de l’entreprise privée n’a pas tenu ses promesses. Il n’a réussi qu’à augmenter la logique procédurale et à faire perdre les repères de métiers et de valeurs du service public. En partant de la théorie de Weber, l’article cherche à démontrer comment les postulats de base de Weber ne correspondent plus à la réalité actuelle des administrations publiques. Dans une période de réduction des moyens consécutive à la crise économique et financière, de complexité et de multiplicité des enjeux et des besoins, de défiance et de perte de confiance à l’égard des élus, les rapports citoyens/élus/administration doivent évoluer vers d’autres formes d’organisation et de prise de décision plus démocratiques et plus efficaces. La décentralisation et les réformes qui l’accompagnent ne pourront réussir sans un changement profond des modes de participation et de régulation entre les élus, l’administration et les citoyens.
