This article examines a series of educational films and documentaries
produced between 1948 and 1968 that document the activities of the Italian state.
These films, which record the dedicated and arduous work of the Italian government
and administration, had two functions. First, they informed students and the
general public about the democratic structures, institutions and aims of the new
republic, promoting a fresh and convincing vision of national identity. Second, they
served to obscure and rewrite the collective national memory of Fascism and Italian
involvement in the Second World War. These films thus reveal the fine line between
public information, political propaganda, and civic education.
Noninvasive inhaled nitric oxide for persistent pulmonary hypertension of the newborn: A single center experience
Authors: Smith D.P. , Perez J.A.
Published: June 2016

INTRODUCTION: Nitric oxide is a potent, selective pulmonary vasodilator that has been proven to decrease pulmonary vascular resistance and has been part of the treatment arsenal for persistent pulmonary hypertension of the newborn (PPHN). In 2009, the approach to the administration of inhaled nitric oxide (iNO) at Winnie Palmer Hospital for Women and Babies (WPH) changed to emphasize avoiding invasive ventilation while maintaining optimal ventilation to perfusion ratio, avoiding hyperventilation and alkalosis agents, and avoiding hyperoxemia and hyperoxia exposure. Our aim is to describe the outcomes of babies whose primary treatment for PPHN was noninvasive (NIV) iNO.

METHODS: A retrospective chart review of neonates born at WPH from October 1, 2009 through October 1, 2014. Inclusion criteria: >34 weeks’ gestation, echocardiographic evidence of PPHN within the first week of life, and NIV iNO as the primary treatment.

RESULTS: Twenty-four babies met criteria: 21 solely treated noninvasively, 3 required invasive support. Supplemental oxygen need was ≥50% for 21 babies pre-iNO treatment and dropped to <30% for all babies post-iNO. Average exposure to supplemental oxygen was 6.3 days. Mean duration of iNO administration was 2.5 days. Average length of stay was 14 days. All babies survived.

CONCLUSION: Our review revealed a low incidence of escalation to invasive ventilation. Non-invasive iNO was found to be an effective and well-tolerated frontline approach for treating PPHN in near-term and term infants with an intact respiratory drive. Further studies could provide the necessary evidence on clinical outcomes as well as cost effectiveness to guide best practice.
Effects of parenteral phosphorus dose restriction in preterm infants
Authors: McNelis K. , Viswanathan S.
Published: June 2016

BACKGROUND: In response to a national shortage of parenteral phosphorus solutions (2013), a hospital-wide phosphorus dose restriction strategies was implemented which included judicious use of phosphorus in preterm infants <1250 g birth weight and no parenteral phosphorus in preterm infants >1250 g birth weight unless they have a critically low phosphorus level.

OBJECTIVE: To study the effect of parenteral phosphorus dose restriction in preterm infants admitted to the neonatal intensive care unit.

METHODS: Preterm infants (≤35 weeks birth gestation and ≤2500 g birth weight) who received parenteral nutrition, survived >1 week and had no major congenital anomalies were studied. Clinical and laboratory data in the first 4 weeks of life of infants admitted during the parenteral phosphorus shortage (cases) were compared to infants who were admitted 6 months prior to the shortage (controls).

RESULTS: Twenty consecutive cases were compared to 40 consecutive controls. Cases had lower serum phosphorus levels, higher serum alkaline phosphatase levels, and need for greater inotropic support compared to controls. These differences were significant only in preterm infants with birth weight >1250 g, the group who received more parenteral phosphorus dose restriction while they were similar in preterm infants with birth weight <1250 g.

CONCLUSION: The modest effects of phosphorus dose restriction may become more clinically important if shortage is prolonged or severe or if it involves extreme preterm infants.

Published: June 2016

Background: Kidney transplantation is the preferred treatment option for end stage kidney disease. Live kidney donation is an established form of organ donation; but it carries the risk of an unnecessary surgery in a normal individual. These donors remain at an increased risk of multiple medical problems for the rest of their life.Objective: In this study, we evaluated the immediate impact of uninephrectomy among kidney donors during the period of post-transplant hospital stay.Materials and Methods: This cross-sectional study was done at BIRDEM General Hospital from January 2006 to June 2014. All kidney donors who had undergone graft nephrectomy during the study period were the study population. All the donors underwent Tc-99m diethylene triamine pentaacetic acid (Tc-99m DTPA) renogram for measurement of glomerular filtration rate (GFR). GFR was also estimated by different equations in both pre-transplant and post-transplant periods. Pre-uninephrectomy GFR and post-uninephrectomy GFR of donors were compared.Results: Total number of subjects was 81, male 48 and female 33. Mean age was 36.3 ± 9.9 years. Mean postoperative hospital stay was 8.2 ± 2.0 days. The mean pre-operative measured glomerular filtration rate (mGFRDTPA) was 99.54 ± 19.06 mL/min/1.73 m2 and mean estimated glomerular filtration rate (eGFRCKD-EPI) was 99.0 ± 18.55 mL/min/1.73 m2 (p=0.855). In post-nephrectomy period mean urine output decreased from 2708.1 ± 842.8 to 2228.4 ± 702.4 mL/day (p=0.000). Mean SBP lowered from 120.3 ± 12.5 to 115.6 ± 9.2 mm of Hg (p=0.000) after nephrectomy. There was significant increase in blood urea (from 19.7 ± 5.7 to 30.4 ± 9.5 mg/dL, p=0.000) and serum creatinine (from 0.90 ± 0.16 to 1.26 ± 0.24 mg/dL, p=0.000) in post-uninephrectomy period. Mean mGFRDTPA of the subjects of non-nephrectomized kidney of the donors was 49.18 ± 9.50 mL/min/1.73 m2 and mean eGFRCKD-EPI of same kidneys was 69.09 ± 16.79 mL/min/1.73m2 (p=0.000) after uni-nephrectomy.Conclusion: Uninephrectomy in healthy adult kidney donors has immediate impacts on urine output, blood pressure, blood urea and serum creatinine levels.J Enam Med Col 2016; 6(2): 71-74
Visual and Textual Sentiment Analysis of a Microblog Using Deep Convolutional Neural Networks
Authors: Yu Yuhai , Lin Hongfei , Meng Jiana , Zhao Zhehuan
Published: June 2016

Sentiment analysis of online social media has attracted significant interest recently. Many studies have been performed, but most existing methods focus on either only textual content or only visual content. In this paper, we utilize deep learning models in a convolutional neural network (CNN) to analyze the sentiment in Chinese microblogs from both textual and visual content. We first train a CNN on top of pre-trained word vectors for textual sentiment analysis and employ a deep convolutional neural network (DNN) with generalized dropout for visual sentiment analysis. We then evaluate our sentiment prediction framework on a dataset collected from a famous Chinese social media network (Sina Weibo) that includes text and related images and demonstrate state-of-the-art results on this Chinese sentiment analysis benchmark.
Pricing Mechanism Design for Centralized Pollutant Treatment with SME Alliances
Authors: Li Yuyu , Huang Bo , Tao Fengming
Published: June 2016

In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how the pollutant treatment price is determined through negotiation. Then, we consider that there is a moral hazard from SMEs in centralized pollutant treatment; in other words, they may break their agreement concerning their quantities of production and pollutant emissions with the pollutant treatment enterprise. We study how the pollutant treatment enterprise can prevent this by pricing mechanism design. It is found that the pollutant treatment enterprise can prevent SMEs’ moral hazard through tiered pricing. If the marginal treatment cost of the pollutant treatment enterprise is a constant, SMEs could bargain with the pollutant treatment enterprise individually, otherwise, they should form a grand alliance to bargain with it as a whole.
Predicting the Flory-Huggins χ Parameter for Polymers with Stiffness Mismatch from Molecular Dynamics Simulations
Authors: Kozuch Daniel , Zhang Wenlin , Milner Scott
Published: June 2016

The Flory–Huggins χ parameter describes the excess free energy of mixing and governs phase behavior for polymer blends and block copolymers. For chemically-distinct nonpolar polymers, the value of χ is dominated by the mismatch in cohesive energy densities of the monomers. For blends of chemically-similar polymers, the entropic portion of χ, arising from non-ideal local packing, becomes more significant. Using polymer field theory, Fredrickson et al. predicted that a difference in backbone stiffness can result in a positive χ for chains consisting of chemically-identical monomers. To quantitatively investigate this phenomenon, we perform molecular dynamic (MD) simulations for bead-spring chains, which differ only in stiffness. From the simulations, we apply a novel thermodynamic integration to extract χ as low as 10 - 4 per monomer for blends with stiffness mismatch. To compare with experiments, we introduce a standardized effective monomer to map real polymers onto our bead-spring chains. The predicted χ agrees well with experimental values for a wide variety of pairs of chemically-similar polymers.
Revising the Modern Moral Paradigm with the Book of Proverbs
Authors: Keefer Arthur
Published: June 2016

The modern moral paradigm champions a codified format, where ethics is conceived of as and conveyed by means of law. Among the wisdom literature of the Hebrew Bible, the book of Proverbs offers an alternative to modern codified morality. I consider a concern shared by ancient and modern societies—communication ethics—to argue that through Proverbs’ focus on character, wisdom, and the Lord, the book could revise the way we think about, articulate, and act upon the modern moral paradigm.
Indirect Correspondence-Based Robust Extrinsic Calibration of LiDAR and Camera
Authors: Sim Sungdae , Sock Juil , Kwak Kiho
Published: June 2016

LiDAR and cameras have been broadly utilized in computer vision and autonomous vehicle applications. However, in order to convert data between the local coordinate systems, we must estimate the rigid body transformation between the sensors. In this paper, we propose a robust extrinsic calibration algorithm that can be implemented easily and has small calibration error. The extrinsic calibration parameters are estimated by minimizing the distance between corresponding features projected onto the image plane. The features are edge and centerline features on a v-shaped calibration target. The proposed algorithm contributes two ways to improve the calibration accuracy. First, we use different weights to distance between a point and a line feature according to the correspondence accuracy of the features. Second, we apply a penalizing function to exclude the influence of outliers in the calibration datasets. Additionally, based on our robust calibration approach for a single LiDAR-camera pair, we introduce a joint calibration that estimates the extrinsic parameters of multiple sensors at once by minimizing one objective function with loop closing constraints. We conduct several experiments to evaluate the performance of our extrinsic calibration algorithm. The experimental results show that our calibration method has better performance than the other approaches.
Soil Seed Bank and Plant Community Development in Passive Restoration of Degraded Sandy Grasslands

Published: June 2016

To evaluate the efficacy of passive restoration on soil seed bank and vegetation recovery, we measured the species composition and density of the soil seed bank, as well as the species composition, density, coverage, and height of the extant vegetation in sites passively restored for 0, 4, 7, and 12 years (S0, S4, S7, and S12) in a degraded grassland in desert land. Compared with S0, three more species in the soil seed bank at depths of 0–30 cm and one more plant species in the community was detected in S12. Seed density within the topsoil (0–5 cm) was five times higher in S12 than that in S0. Plant densities in S7 and S12 were triple and quadruple than that in S0. Plant coverage was increased by 1.5 times (S4), double (S7), and triple (S12) compared with S0. Sørensen’s index of similarity in species composition between the soil seed bank and the plant community were high (0.43–0.63), but it was lower in short-term restoration sites (S4 and S7) than that in no and long-term restoration sites (S0 and S12). The soil seed bank recovered more slowly than the plant community under passive restoration. Passive restoration is a useful method to recover the soil seed bank and vegetation in degraded grasslands.
High in Vitro Anti-Tumor Efficacy of Dimeric Rituximab/Saporin-S6 Immunotoxin

Published: June 2016

The anti-CD20 mAb Rituximab has revolutionized lymphoma therapy, in spite of a number of unresponsive or relapsing patients. Immunotoxins, consisting of toxins coupled to antibodies, are being investigated for their potential ability to augment Rituximab efficacy. Here, we compare the anti-tumor effect of high- and low-molecular-weight Rituximab/saporin-S6 immunotoxins, named HMW-IT and LMW-IT, respectively. Saporin-S6 is a potent and stable plant enzyme belonging to ribosome-inactivating proteins that causes protein synthesis arrest and consequent cell death. Saporin-S6 was conjugated to Rituximab through an artificial disulfide bond. The inhibitory activity of HMW-IT and LMW-IT was evaluated on cell-free protein synthesis and in two CD20+ lymphoma cell lines, Raji and D430B. Two different conjugates were separated on the basis of their molecular weight and further characterized. Both HMW-IT (dimeric) and LMW-IT (monomeric) maintained a high level of enzymatic activity in a cell-free system. HMW-IT, thanks to a higher toxin payload and more efficient antigen capping, showed stronger in vitro anti-tumor efficacy than LMW-IT against lymphoma cells. Dimeric HMW-IT can be used for lymphoma therapy at least for ex vivo treatments. The possibility of using HMW-IT augments the yield in immunotoxin preparation and allows the targeting of antigens with low internalization rates.
Lambda gpP-DnaB Helicase Sequestration and gpP-RpoB Associated Effects: On Screens for Auxotrophs, Selection for RifR, Toxicity, Mutagenicity, Plasmid Curing
Authors: Hayes Sidney , Wang Wen , Rajamanickam Karthic , Chu Audrey , Banerjee Anirban , Hayes Connie
Published: June 2016

The bacteriophage lambda replication initiation protein P exhibits a toxic effect on its Escherichia coli (E. coli) host, likely due to the formation of a dead-end P-DnaB complex, sequestering the replicative DnaB helicase from further activity. Intracellular expression of P triggers SOS-independent cellular filamentation and rapidly cures resident ColE1 plasmids. The toxicity of P is suppressed by alleles of P or dnaB. We asked whether P buildup within a cell can influence E. coli replication fidelity. The influence of P expression from a defective prophage, or when cloned and expressed from a plasmid was examined by screening for auxotrophic mutants, or by selection for rifampicin resistant (RifR) cells acquiring mutations within the rpoB gene encoding the β-subunit of RNA polymerase (RNAP), nine of which proved unique. Using fluctuation assays, we show that the intracellular expression of P evokes a mutator effect. Most of the RifR mutants remained PS and localized to the Rif binding pocket in RNAP, but a subset acquired a PR phenotype, lost sensitivity to ColE1 plasmid curing, and localized outside of the pocket. One PR mutation was identical to rpo*Q148P, which alleviates the UV-sensitivity of ruv strains defective in the migration and resolution of Holliday junctions and destabilizes stalled RNAP elongation complexes. The results suggest that P-DnaB sequestration is mutagenic and supports an earlier observation that P can interact with RNAP.
Mouse Systems to Model Hepatitis C Virus Treatment and Associated Resistance
Authors: Mesalam Ahmed , Vercauteren Koen , Meuleman Philip
Published: June 2016

While addition of the first-approved protease inhibitors (PIs), telaprevir and boceprevir, to pegylated interferon (PEG-IFN) and ribavirin (RBV) combination therapy significantly increased sustained virologic response (SVR) rates, PI-based triple therapy for the treatment of chronic hepatitis C virus (HCV) infection was prone to the emergence of resistant viral variants. Meanwhile, multiple direct acting antiviral agents (DAAs) targeting either the HCV NS3/4A protease, NS5A or NS5B polymerase have been approved and these have varying potencies and distinct propensities to provoke resistance. The pre-clinical in vivo assessment of drug efficacy and resistant variant emergence underwent a great evolution over the last decade. This field had long been hampered by the lack of suitable small animal models that robustly support the entire HCV life cycle. In particular, chimeric mice with humanized livers (humanized mice) and chimpanzees have been instrumental for studying HCV inhibitors and the evolution of drug resistance. In this review, we present the different in vivo HCV infection models and discuss their applicability to assess HCV therapy response and emergence of resistant variants.

Hepatitis B virus (HBV) has long been recognized as an occupational risk for healthcare workers (HCWs) as a result of regular and routine exposure to blood and other body fluids in the course of their duties. The risk of occupational exposure to such infection has been the concerns of HCWs for years. However, there were scarcities of information on frequency of Hepatitis B virus infection in the study area. This study aimed to determine the seroprevalence of Hepatitis B surface antigenaemia among Health Care Workers in Babcock University Teaching Hospital, Ilisan, Nigeria. A descriptive, cross-sectional study conducted among HCWs from across various occupation categories in the study area between May and June 2015. A structured questionnaire was used to collect demographics and clinical data. Sample analytical process was carried out using the HBsAg commercially available kits (Genedia, Green Cross, Korea). Of the 100 HCWs enrolled in the study, HBsAg was detected in 7%. The positivity of HBsAg, in this study, was more among males and all were from staff younger than 50 years old. The occupational risk of HBV infection among the HCWs in this study was highest among the cleaning staff followed by nurses and doctors. None was documented among the Medical laboratory Scientists/technicians. The occupation risk of HBV infection among the HCWs in this study was high. Regular Infection prevention and control training is required and HBV vaccine should be more readily available for HCWs by coordinated institutional vaccination programs.
Unraveling the biogeographical history of Chrysobalanaceae from plastid genomes

PREMISE OF THE STUDY:

The complex geological and climatic history of the Neotropics has had major implications on the diversification of plant lineages. Chrysobalanaceae is a pantropical family of trees and shrubs with 75% of its 531 species found in the Neotropics, and a time‐calibrated phylogeny of this family should shed light on the tempo of diversification in the Neotropical flora. Previously published phylogenetic hypotheses of this family were poorly supported, and its biogeography remains unclear.

METHODS:

We assembled the complete plastid genome of 51 Chrysobalanaceae species, and increased taxon sampling by Sanger‐sequencing of five plastid regions for an additional 88 species. We generated a time‐calibrated tree including all 139 Chrsyobalanaceae species and 23 outgroups. We then conducted an ancestral area reconstruction analysis and estimated diversification rates in the family.

KEY RESULTS:

The tree generated with the plastid genome alignment was almost fully resolved. It supports the polyphyly of Licania and Hirtella. The family has diversified starting around the Eocene‐Oligocene transition. An ancestral area reconstruction confirms a Paleotropical origin for Chrysobalanaceae with several transoceanic dispersal events. The main Neotropical clade likely resulted from a single migration event from Africa around 28 mya ago, which subsequently underwent rapid diversification.

CONCLUSIONS:

Given the diverse ecologies exhibited by extant species, we hypothesize that the rapid diversification of Chrysobalanaceae following the colonization of the Neotropics was triggered by habitat specialization during the complex geological and paleoclimatic history of the Neotropics.
Prototyping a remotely-controlled machine for concrete surface grinding operations
Authors: MOON Sungwoo , KIM Jeonghwan , SEO Jongwon
Published: June 2016

The surface of concrete pavement needs to be flattened for the smoothness and comfortability of highways. Surface grinding can provide flatness in the hardened concrete surface, and improve adhesion between the existing con­crete surface and the subsequent layer. The surface grinding process, however, is executed under hazardous work condi­tions and the outcome is affected by a machine operator’s skill. Automation of this process can provide a hazard-free work environment and increase the quality of the ground surface. This paper presents an application of an automated concrete surface grinding machine that an operator can remotely control with computer assistance. A combination of hardware and software technologies was applied to prototype automated functions of the machine. Field tests demon­strated that remote control of concrete surface grinding is feasible and can be utilized as a semi-automated scheme on actual construction sites.

We report Shanghai Tian Ma Radio Telescope (TMRT) detections of several long carbon-chain molecules in the C and Ku bands, including HC3N, HC5N, HC7N, HC9N, C3S, C6H, and C8H toward the starless cloud Serpens South 1a. We detected some transitions (HC9N J = 13–12, F = 12–11, and F = 14–13; H13CCCN J = 2–1, F = 1–0, and F = 1–1; HC13CCN J = 2–1, F = 2–2, F = 1–0, and F = 1–1; HCC13CN J = 2–1, F = 1–0, and F = 1–1) and resolved some hyperfine components (HC5N J = 6–5, F = 5–4; H13CCCN J = 2–1, F = 2–1) for the first time in the interstellar medium. The column densities of these carbon-chain molecules in the range 1012–1013 cm−2 are comparable to two carbon-chain molecule rich sources, TMC-1 and Lupus-1A. The abundance ratios are 1.00:(1.11 ± 0.15):(1.47 ± 0.18) for [H13CCCN]:[HC13CCN]:[HCC13CN]. This result implies that the 13C isotope is also concentrated in the carbon atom adjacent to the nitrogen atom in HC3N in Serpens South 1a, which is similar to TMC-1. The [HC3N]/[H13CCCN] ratio of 78 ± 9, the [HC3N]/[HC13CCN] ratio of 70 ± 8, and the [HC3N]/[HCC13CN] ratio of 53 ± 4 are also comparable to those in TMC-1. Serpens South 1a proves to be a suitable testing ground for understanding carbon-chain chemistry.
CONSTRAINTS ON MACHO DARK MATTER FROM COMPACT STELLAR SYSTEMS IN ULTRA-FAINT DWARF GALAXIES
Authors: Brandt Timothy D.
Published: June 2016

I show that a recently discovered star cluster near the center of the ultra-faint dwarf galaxy Eridanus II provides strong constraints on massive compact halo objects (MACHOs) of ≳5 M
⊙ as the main component of dark matter. MACHO dark matter will dynamically heat the cluster, driving it to larger sizes and higher velocity dispersions until it dissolves into its host galaxy. The stars in compact ultra-faint dwarf galaxies themselves will be subject to the same dynamical heating; the survival of at least 10 such galaxies places independent limits on MACHO dark matter of masses ≳10 M
⊙. Both Eri II’s cluster and the compact ultra-faint dwarfs are characterized by stellar masses of just a few thousand M
⊙ and half-light radii of 13 pc (for the cluster) and ∼30 pc (for the ultra-faint dwarfs). These systems close the ∼20–100 M
⊙ window of allowed MACHO dark matter and combine with existing constraints from microlensing, wide binaries, and disk kinematics to rule out dark matter composed entirely of MACHOs from ∼10−7
M
⊙ up to arbitrarily high masses.
Elvitegravir/Cobicistat-Associated Toxic Optical Neuropathy in an HIV-Infected Patient: A Call for Caution?
Authors: Riva Agostino , Invernizzi Alessandro , Resnati Chiara , Micheli Valeria , Cattaneo Dario , Gervasoni Cristina
Published: June 2016

Ocular toxicity may not only be caused by medication overdoses and drug–drug interactions, but also by chronic administration of medications at recommended doses. We describe a case of an HIV-infected patient who experienced significant and sustained bilateral visual loss 2 months after starting treatment with elvitegravir/cobicistat/tenofovir/emtricitabine. Given the absence of any evidence of tenofovir- or emtricitabine-induced optical neuropathy after several years of clinical use, the antiretroviral therapy was promptly changed to tenofovir/emtricitabine plus atazanavir/ritonavir, which led to a progressive improvement in visual acuity. However, visual evoked potentials never returned to normal amplitudes. This is the first report of toxic optical neuropathy associated with the use of elvitegravir/cobicistat. It is imperative to recognize any signs of possible eye toxicity as rapidly as possible, and refer affected patients to an ophthalmologist promptly because early detection and the withdrawal of the offending agent are crucial in reversing this adverse ocular event.
Les relations entre les perceptions des conflits et des enrichissements travail-famille et le bien-être

Published: June 2016

Des études ont montré que les organisations soucieuses de leur performance, de leur capacité d’attraction et de fidélisation du personnel et de leur responsabilité sociale doivent se soucier du bien-être de leurs employés. Pour les employeurs, il importe donc de mieux comprendre les déterminants du bien-être des employés afin de pouvoir l’optimiser. Cette étude innove en explorant les liens entre les perceptions des employés à l’égard des conflits et des enrichissements entre leurs vies professionnelle et personnelle et leur bien-être tant subjectif que psychologique. Cette recherche a été menée par questionnaire auprès de 798 cadres ou professionnels. Les résultats confirment que (1) plus les répondants ressentent des conflits « travail-famille » et des conflits « famille-travail » élevés, moins ils expriment de bien-être, tant subjectif que psychologique ; (2) plus les cadres et les professionnels perçoivent des enrichissements « travail-famille » élevés, plus ils ressentent de bien-être subjectif. Toutefois, les liens positifs attendus entre les perceptions des enrichissements « famille-travail » et le bien-être psychologique s’avèrent statistiquement significatifs pour les hommes seulement. Des implications pour la recherche et la pratique sont décrites notamment, à l’égard de l’organisation du travail, de l’appui que peuvent offrir les organisations et du changement des croyances quant à l’opposition des rôles professionnels et personnels.
Les effets du sentiment d’efficacité personnelle sur la relation entre l’équilibre travail-famille et la satisfaction au travail
Authors: Garner Pierre , Laroche Patrice
Published: June 2016

Cette recherche s’intéresse aux relations entre l’équilibre travail-famille, le sentiment d’efficacité personnelle et la satisfaction au travail. Une enquête par questionnaires a été réalisée auprès d’un échantillon de 232 cadres de PME du bassin lorrain. Les résultats de l’étude montrent, d’une part, que le conflit travail-famille – lié au stress – est associé négativement à la satisfaction au travail et d’autre part, que le sentiment d’efficacité personnelle modère de façon significative les effets négatifs du conflit travail/famille sur la satisfaction au travail. L’analyse fait ressortir deux dimensions relevant du sentiment d’efficacité personnelle qui s’avèrent agir différemment sur la relation conflit travail/famille lié au stress et la satisfaction au travail. Ainsi, la rétroaction perçue d’efficacité personnelle – c’est-à-dire la perception d’un individu sur la manière dont sa hiérarchie juge l’efficacité de son travail – semble accentuer les effets négatifs du conflit travail-famille sur la satisfaction au travail.
Politiques de la cinéphilie : la parole féminine dans les magazines populaires des années 1950
Authors: Pillard Thomas
Published: June 2016

Analyser la culture populaire implique de s’intéresser aux rapports que ses usagers entretiennent avec les objets que les industries culturelles produisent et diffusent à leur attention. Dans cette perspective, nous examinerons la réception féminine du cinéma de consommation courante dans les années 1950, à partir d’une analyse du courrier des lecteurs du périodique Le Film complet , un magazine populaire principalement lu par des femmes. Il s’agira de montrer l’essor durant cette période d’une « cinéphilie au féminin » se caractérisant par des dynamiques contre-hégémoniques élaborées en réaction à l’élitisme de la cinéphilie savante, au masculinisme de la production cinématographique ainsi qu’à l’organisation masculine et patriarcale de la société dans son ensemble.
Le singulier collectif. L’auteur à travers ses réseaux
Authors: Alexandre Olivier , Lamberbourg Adeline
Published: June 2016

Cet article vise à croiser les apports de la sociologie de l’art et de l’analyse de réseaux à partir du cas du cinéma français. Il est principalement le résultat de deux enquêtes respectivement menée entre 2004 et 2006, puis 2008 et 2012 auprès d’une population de « talents » (réalisateurs, acteurs, chefs de poste et techniciens) et d’intermédiaires (producteurs, distributeurs, critiques, exploitants). Au-delà d’un discours fortement individualisant (la « politique des auteurs »), le cinéma français permet de rendre compte de chaînes de réseaux imbriqués, allant du plus resserré (dyades) au plus étendu (« famille »). Cette trame relationnelle constitue une structure du travail créateur et des économies par projet, indéterminées, précaires et incertaines.

Published: June 2016

Purpose: to describe the factors that facilitate the adoption of e-business in firms. To go in deep on the factors, resources and capabilities that need to be present in those firms seeking to improve their levels of e-business adoption.Design/methodology/approach: analysis of the literature involving the main theories on business administration, and more specifically, on those related to technology innovation (TI) and information systems (IS), as applicable to the organizational factors that explain the adoption of e-business.Findings: it identifies three main sources of influence: a first group covers the characteristics of the actual firm, which refer to the organisation’s specific features: firm size, the backing of top management, expected benefit, age, the level of human capital, and international projection.

Channel Attenuation Models over Ka Band Satellite Systems at Venezuelan Amazonian Area
Authors: Guedez Gustavo , Qiang Gao
Published: June 2016

The progressive congestion of the spectrum at low frequency bands, has obliged the need to use new systems which operate in higher frequencies, such as the Ka bands. The quality and availability of the signals in Ka band are seriously degraded by various climate phenomena, especially in the Amazon area. To keep the link properties in normal conditions (similar to clear sky conditions), is necessary to know the attenuation losses over the service area or footprint. For the Venezuelan Amazon region only Attenuation by atmospheric gases, Attenuation by rain and Scintillation and multipath effects, could be considered according to the ITU. The attenuation calculation is the first step to estimate the link budget and implement any communication service over Ka Band in the Venezuelan Amazon region. The aim of this research is modeling the channel attenuation for Ka band satellite signals and find a suitable attenuation data.

Authors: Suyono Eko Agus , Listyarini Anis , Hardiyati Anisa
Published: June 2016

Chlorella zofingiensis Dönz is not only known as feed in aquaculture industry, but also it has been developed as biodiesel source. In order to optimize the microalgae as a biodiesel feedstock, it is necessary to study its environmental factors, such as light and medium salinity. This study was conducted to determine the effect of red-blue light in a wide range of salinity medium. C. zofingiensis Dönz used in this study were cultured for 21 days on a laboratory scale using a medium consisted of ZA, Urea and Farmpion (local agriculture fertilizer) with a ratio of 4: 2: 1. There were three variations of salinity treatments, including culture without the addition of NaCl (its medium salinity was 14 ppm); the addition of NaCl 5 ppm (its medium salinity was 19 ppm) and NaCl 10 ppm (its medium salinity was 24 ppm). Its cell density and dry weight were measured every 7 days. Neutral lipid content was determined with Nile Red staining method and analyzed with CellProfiler software every 7 days. The highest lipid content was achieved by treatment of blue light and the addition of NaCl 5 ppm, accounted for 344.6 mg L-1 or 50% of the dry weight.

Published: June 2016

Plate is one of the most common structural elements, which appears in a wide range of applications: steel bridges, blast-resistance door, and armored vehicles. In this paper, the behavior of steel plates under blast loading was studied through numerical approaches using LS DYNA and then the results were compared with the experiment results obtained from existing literatures. The study of a clamped square plate exposed to blast loading in three distinct stand-off distances. Three different methods of modeling blast loading were used, namely: empirical blast method, arbitrary Lagrangian Eulerian (ALE) method, and coupling of Lagrangian and Eulerian method. The empirical blast method was deployed by using key card *LOAD_BLAST in LS-DYNA. In ALE method, Langrangian and Eulerian solution were combined in the same model and the fluid-structure interaction (FSI) handled by coupling algorithm. In coupling method, the engineering load blast in LS-DYNA (*LOAD_BLAST_ENHANCED) was coupled with the ALE solver. In terms of central deflection and computational time, the coupling method appeared to be the best method which is very time-effective and showed a good correlation with the experiment data.

Photometric stereo works on recovering the shape and reflectance properties of an object using multiple images taken in variable lighting conditions. In this study, a system has been implemented to construct a height field from 12 images of an object. The algorithm which is able to calibrate the lighting direction, find the normals and color albedo at each pixel have been optimized to compute the surface which best fit the normals. This algorithm was also implemented to the welding product to reconstruct the shape of welding bead.

Published: June 2016

The objective of this study was to translate and adapt five English self-report health measures to a South Indian language Kannada. Currently, no systematically developed questionnaires assessing hearing rehabilitation outcomes are available for clinical or research use in Kannada. The questionnaires included for translation and adaptation were the hearing handicap questionnaire, the international outcome inventory - hearing aids, the self-assessment of communication, the participation scale, and the assessment of quality of life – 4 dimensions. The questionnaires were translated and adapted using the American Association of Orthopedic Surgeons (AAOS) guidelines. The five stages followed in the study included: i) forward translation; ii) common translation synthesis; iii) backward translation; iv) expert committee review; v) pre-final testing. In this paper, in addition to a description of the process, we also highlight practical issues faced while adopting the procedure with an aim to help readers better understand the intricacies involved in such processes. This can be helpful to researchers and clinicians who are keen to adapt standard self-report questionnaires from other languages to their native language.

Published: June 2016

It has been shown that frailty is associated with low levels of wellbeing and life satisfaction. Further exploration is needed, however, to better understand which components constitute life satisfaction for frail older people and how satisfaction is related to other life circumstances. The aim of this study was to examine relationships between frail older people’s life satisfaction and their socioeconomic conditions, social networks, and health-related conditions. A cross-sectional study was conducted (n=179). A logistic regression analysis was performed, including life satisfaction as the dependent variable and 12 items as independent variables. Four of the independent variables made statistically significant contributions: financial situation (OR 3.53), social contacts (OR 2.44), risk of depression (OR 2.26), and selfrated health (OR 2.79). This study demonstrates that financial situation, self-rated health conditions and social networks are important components for frail older people’s life satisfaction. Health and social care professionals and policy makers should consider this knowledge in the care and service for frail older people; and actions that benefit life satisfaction − such as social support − should be promoted.

A comparative analysis of the implementation of anti-corruption legislation by anti-corruption agencies in the provinces of the Eastern and Northern Cape
Authors: Majila Thozama , Taylor John Derek , Raga Kishore
Published: June 2016

Many countries experience various degrees of corruption. South Africa is no exception. The undeniable fact is that corruption cannot be reckoned as a mere country- or region- specific problem; it is a far wider phenomenon. However, there has been a growing global movement to condemn corrupt practices, resulting in the removal of certain leaders from office. South Africa has formulated and promulgated legislation that is considered an international example of good practice and has established agencies for the purpose of combating corruption. The Institute for Security Studies (2007:1) proposes that anti-corruption legislation, if enforced, should equip the country’s anti-corruption agencies with a tool that could effectively be utilised as a punitive instrument for offenders and a deterrent for those contemplating corrupt activities.This article examines whether anti-corruption agencies are apolitical and capable of detecting and punishing corruption or whether they are only a response to international demands by international agreements. In this regard the United Nations Convention against Corruption, the SADC Protocol against Corruption and the African Union Convention on Preventing and Combating Corruption are discussed.The article concludes with recommendations based on an empirical survey of anti- corruption legislation and anti-corruption agencies conducted in the Eastern Cape and Northern Cape Provinces.
The role of musical experience in the lives of Williams syndrome individuals
Authors: Erasmus Ewie
Published: June 2016

The purpose of this literature study is to better understand the musical experiences of those diagnosed with Williams syndrome. The problem of this study is defined by the lack of qualitative studies done on the musical experiences of Williams syndrome individuals. Research done on music and Williams syndrome emphasise the intense affinity that those diagnosed show towards music listening and music making, yet very few qualitative studies have been done on the importance of musical experience in the everyday lives of those diagnosed with Williams syndrome. The study at hand will provide insight into the lives of individuals with Williams syndrome, while focussing on the importance of musical experience, raising the awareness of caretakers, educators, therapists and researchers. This qualitative study was aided by Atlas.ti 7 computer software which assisted me in document analysis through a grounded theory approach. For the data analysis process, significant statements were identified and then coded. These codes were then sorted to reveal categories and main themes. Literature revealed that music could in fact play an important role in the lives of those living with Williams syndrome. Musical experience does not only have a positive influence on a single aspect of the lives of Williams syndrome individuals, it has an impact on their lives in general, influencing their overall well-being.
