Percutaneous pinning versus volar locking plate internal fixation for unstable distal radius fractures: a meta-analysis
Authors: Peng Fei , Liu Yuan-xiang , Wan Zhen-yu
Published: October 2017

This meta-analysis compared outcomes between percutaneous pinning/wiring and open reduction internal fixation (ORIF) with locking plates for treatment of unstable distal radius fractures. Medline, Cochrane, EMBASE, and Google Scholar were searched through December 30, 2015. Twenty randomised controlled trials (RCTs) and non-randomised two-arm studies were included. Outcomes included scores of Disabilities of the Arms, Shoulders and Hands (DASH), visual analogue scale (VAS) pain, and patient rated wrist evaluation (PRWE) score, as well as range of motion (ROM) and complication incidence. ORIF/plating was associated with lower DASH scores but longer procedure time, while there was no difference between the two methods with respect to VAS pain score and PRWE score. The overall incidence of complications, including complex regional pain syndrome, was higher with pinning/wiring, though the incidence of carpal tunnel syndrome and nerve defects was not different. Supination and grip strength were better with ORIF. Radiographically, ulnar variation was greater with pinning/wiring. These results suggest that ORIF/plating is the preferred method of managing unstable distal radius fractures.

Perinatal management of hepatitis B virus: Clinical implementation of updated Australasian management guidelines
Authors: Bergin Hannah , Wood Gillian , Walker Susan P , Hui Lisa
Published: October 2017

Objective

To evaluate the implementation of the 2013 Royal Australian and New Zealand College of Obstetricians and Gynaecologists ‘Management of Hepatitis B in Pregnancy’ guideline.

Methods

Retrospective cohort study of the clinical management and obstetric outcomes among hepatitis B virus-positive women in a single tertiary maternity hospital. Women with viral load >200,000 IU/ml were referred to a specialised clinic for consideration of tenofovir disoproxil fumarate therapy to reduce mother to child transmission.

Results

A total of 11,496 women gave birth during the study period, of which 101 (0.9%) women were hepatitis B virus positive. Viral load was measured in 99 (98%) of 101 hepatitis B virus-positive women; 30 (30%) had a viral load >200,000 IU/ml. Twenty-six women accepted tenofovir disoproxil fumarate; of these, 23 had a successful virological response (viral load <200,000 IU/ml before delivery).

Conclusions

Adherence to updated management guidelines and patient acceptance of tenofovir disoproxil fumarate in our Australian population were high when provided in the context of a dedicated perinatal service.
Collaborative Comanagement Between Neurohospitalists and Internal Medicine Hospitalists Decreases Provider Costs and Enhances Satisfaction With Neurology Care at an Academic Medical Center
Authors: Greene James G.
Published: October 2017

Background and Purpose:

The majority of academic medical centers are moving to a neurohospitalist model of care for hospital neurology coverage. Potential benefits over a more traditional academic model of patient care include greater expertise in acute neurologic disease, increased efficiency, and improved availability to patients, providers, and learners. Despite these perceived advantages, switching to a neurohospitalist model can come at substantial financial cost, so finding ways to maximize the positive impact of a limited number of neurohospitalists is very important to the future health of academic neurology departments. Over the past 7 years, we have implemented a model for inpatient neurological care based on an intimate collaborative relationship between the neurology and hospital medicine services at our main academic hospital. Our goal was to optimize the value of care by decreasing cost while improving quality.

Methods:

Cost and revenue associated with professional services was evaluated on a yearly basis. As part of ongoing quality improvement efforts, yearly surveys were administered to referring providers during the transition to a collaborative care model in which NHs and medicine hospitalists comanage neurology inpatients.

Results:

Net operating loss was dramatically decreased upon transition to the new care model. Concomitantly, there was a robust positive impact on perception of overall quality, timeliness, and communication skills of neurology services.

Conclusions:

Collaborative comanagement is an effective strategy to improve overall satisfaction with neurology services at a tertiary academic medical center while maintaining financial viability.
Non‐invasive imaging of global and regional cardiac function in pulmonary hypertension
Authors: Crowe Tim , Jayasekera Geeshath , Peacock Andrew J.
Published: October 2017

Pulmonary hypertension (PH) is a progressive illness characterized by elevated pulmonary artery pressure; however, the main cause of mortality in PH patients is right ventricular (RV) failure. Historically, improving the hemodynamics of pulmonary circulation was the focus of treatment; however, it is now evident that cardiac response to a given level of pulmonary hemodynamic overload is variable but plays an important role in the subsequent prognosis. Non‐invasive tests of RV function to determine prognosis and response to treatment in patients with PH is essential. Although the right ventricle is the focus of attention, it is clear that cardiac interaction can cause left ventricular dysfunction, thus biventricular assessment is paramount. There is also focus on the atrial chambers in their contribution to cardiac function in PH. Furthermore, there is evidence of regional dysfunction of the two ventricles in PH, so it would be useful to understand both global and regional components of dysfunction. In order to understand global and regional cardiac function in PH, the most obvious non‐invasive imaging techniques are echocardiography and cardiac magnetic resonance imaging (CMRI). Both techniques have their advantages and disadvantages. Echocardiography is widely available, relatively inexpensive, provides information regarding RV function, and can be used to estimate RV pressures. CMRI, although expensive and less accessible, is the gold standard of biventricular functional measurements. The advent of 3D echocardiography and techniques including strain analysis and stress echocardiography have improved the usefulness of echocardiography while new CMRI technology allows the measurement of strain and measuring cardiac function during stress including exercise. In this review, we have analyzed the advantages and disadvantages of the two techniques and discuss pre‐existing and novel forms of analysis where echocardiography and CMRI can be used to examine atrial, ventricular, and interventricular function in patients with PH at rest and under stress.
Organizational correlates of continuity of care: A pendulum swing between differentiation and integration
Authors: Longo Francesco , Salvatore Domenico , Tasselli Stefano , Petracca Francesco
Published: October 2017

Introduction

Continuity of care is among the foundations of primary care and has long been identified as a critical determinant of healthcare outcomes. This article aims to assess through an empirical study the relationships between distinct organizational features (namely, the use of clinical pathways and clinical databases, and the centralization of healthcare setting or provider) and types of patient-perceived continuity of care.

Methods

A multilevel regression model was performed, analyzing survey data on patient-perceived continuity of care and on the organization of care for three specific chronic conditions (chronic obstructive pulmonary disease, diabetes and late-stage cancer). A total of 497 healthcare professional responses (79% response rate) and 323 patient responses were collected in 13 Italian Local Health Authorities.

Results

Clinical pathways have a statistically significant and positive effect on relational continuity ( p ≤ 0.01), while centralization of care in one professional improves the perceived quality of the relationship from a longitudinal perspective. A small, but statistically significant, improvement in continuity of care was detected when services are taken out of the hospital. No statistical significant effect of the use of clinical databases by professionals was found.

Conclusions

Although largely neglected, organizational features can impact the continuity of care experienced by patients. The higher prevalence of chronic conditions should push modern health systems for more extensive attention towards organizational strategies aimed at enhancing continuity of care.
Show Me the Money: Importance of Crowdfunding Factors on Backers’ Decisions to Financially Support Kickstarter Campaigns
Authors: Colistra Rita , Duvall Kevin
Published: October 2017

Through the use of an online survey and supporting interviews of funders, this study explores which factors are most influential in people’s decisions to financially back Kickstarter projects. Findings suggest that Kickstarter has several distinct benefits for those who support its projects and offers them an experience that traditional production channels cannot. The results also indicate that backers typically feel involved in the process of creating the projects they support, and they are willing to take risks to see projects that are important to them come to fruition. This research helps to improve our understanding of the attitudes that drive Kickstarter funding, and it helps project creators know what aspects of their campaigns prospective supporters find most important.

We describe the case of a 67-year-old male presenting with significant NF in his left lower extremity, despite aggressive surgical intervention, and included multiple surgical debridements, ACell Matrix, split-thickness, and negative wound VAC therapy. Ultimately, this patient required a below the knee amputation. This is the first documented case of Haemophilus influenza type a causing NF.
The crystal-chemistry of riebeckite, ideally Na2Fe32+ Fe23+Si8O22(OH)2: a multi-technique study
Authors: Susta Umberto , Della Ventura Giancarlo , Hawthorne Frank C. , Abdu Yassir A. , Day Maxwell C. , Mihailova Boriana , Oberti Roberta
Published: October 2017

In this work we report on a complete crystal-chemical characterization of a near end-member riebeckite from Malawi, and use the available data to critically compare information obtained from different analytical methods. The sample occurs as well-formed and very large single crystals in pegmatitic rocks. Accurate site-populations were determined by combining single-crystal structure refinement and electron microprobe analysis (EMPA). The Fe3+/Fe2+ ratio was obtained from Mössbauer spectroscopy. Lithium was quantified by Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS).

Fourier-Transform Infrared (FTIR) spectra, collected both on powders and single crystals, are presented and discussed. FTIR spectra in the NIR region are also presented for the first time for this amphibole. The FTIR data are compatible with complete local ordering of A cations close to F, and complete Fe2+/Mg disorder at M(1,3). Polarized Raman-scattering data collected from single crystals confirm this conclusion. In addition, it was found that FTIR data collected on powders provide the best agreement with the site occupancies derived from chemical (EMPA and LA-ICP-MS) and crystal-chemical data, possibly because they do not depend on experimental issues such as orientation and polarization.
Gortdrumite, Cu24Fe2Hg9S23, from Leogang, Salzburg, Austria: crystal structure and revision of the chemical formula
Authors: Bindi Luca , Paar Werner H. , Leblhuber Peter
Published: October 2017

The crystal structure of the mineral gortdrumite, a rare copper-mercury-iron sulfide, was solved using intensity data collected using a crystal from the Neuschurf adit, Leogang, Salzburg, Austria. This study revealed that the structure is triclinic, space groupP$\bar 1$, with cell parameters:a= 9.677(4),b= 9.865(5),c= 11.992(5) Å, α = 77.85(4), β = 79.42(3), γ = 76.30(4)°,V= 1076.5(8) Å3andZ= 1. The refinement led to anRindex of 0.0833 for 3335 independent reflections and 143 parameters. Twelve S sites (one with half occupancy) and eighteen metal sites (5 Hg, 12 Cu and 1 Fe) occur in the crystal structure of gortdrumite. Mercury cations link two sulfur atoms in a linear coordination, Cu cations are found in various low-coordination (2, 3 and 4) sites, in agreement with the Cu preference for such environments, and Fe in tetrahedral coordination. Metal–metal interactions are also present and these contacts are discussed in relation with other copper sulfides, intermetallics and pure metals. Electron microprobe analyses of the crystal used for the structural study led to the formula Cu24.83Fe1.73Hg9.09S22.35, on the basis of 58 atoms. On the basis of information gained from the structural and chemical characterization, the crystal-chemical formula was revised to Cu24Fe2Hg9S23(Z= 1) instead of (Cu,Fe)6Hg2S5as reported previously.

A new mineral arsenowagnerite, Mg2(AsO4)F, the arsenate analogue of wagnerite, was found in sublimates of the Arsenatnaya fumarole at the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka, Russia. It is associated closely with johillerite, tilasite, anhydrite, hematite, fluorophlogopite, cassiterite, calciojohillerite, aphthitalite and fluoborite. Arsenowagnerite occurs as equant to tabular crystals up to 1 mm across combined in interrupted crusts up to 0.1 cm × 1.5 cm × 3 cm. The mineral is transparent, light yellow, lemon-yellow, greenish-yellow or colourless and has a vitreous lustre. Arsenowagnerite is brittle, with Mohs hardness of ~5. Cleavage is distinct, the fracture is uneven. Dcalc = 3.70 g cm–3. Arsenowagnerite is optically biaxial (+), α = 1.614(2), β = 1.615(2), γ = 1.640(2) and 2Vmeas = 25(5)°. Wavenumbers of the strongest absorption bands in the IR spectrum (cm–1) are: 874, 861, 507, 491 and 470. The chemical composition (average of six electron-microprobe analyses, wt.%) is: MgO 38.72, CaO 0.23, MnO 0.32, CuO 0.60, ZnO 0.05, Fe2O3 0.11, TiO2 0.03, SiO2 0.08, P2O5 0.18, V2O5 0.03, As2O5 54.96, SO3 0.10, F 8.91 and –O=F –3.75, total 100.57. The empirical formula calculated on the basis of 5 (O + F) apfu is: (Mg1.98Cu0.02Mn0.01Ca0.01)Σ2.02(As0.99P0.01)Σ1.00O4.03F0.97. Arsenowagnerite is monoclinic, P21/c, a = 9.8638(3), b = 12.9830(3), c = 12.3284(3) Å, β = 109.291(3)°, V = 1490.15(7) Å3 and Z = 16. The strongest reflections of the powder X-ray diffraction pattern [d,Å(I)(hkl)] are: 5.80(41)(002), 5.31(35)(120), 3.916(37)($\bar 2$21), 3.339(98)(221, 023), 3.155(65)(202), 3.043(100)($\bar 1$41), 2.940(72)($\bar 2$04), 2.879(34)($\bar 3$22) and 2.787(51)(320, $\bar 1$24). The crystal structure was solved from single-crystal X-ray diffraction data, R = 0.0485. Arsenowagnerite is isostructural to wagnerite-Ma2bc. The crystal structure is built by almost regular AsO4 tetrahedra, distorted MgO4F2 octahedra and distorted MgO4F trigonal bipyramids.

Mediastinal lymph node enlargement is common in the follow-up of patients with previously treated malignancies. The aim of this study is to assess the role of endobronchial ultrasound (EBUS) transbronchial needle aspiration (TBNA) for cyto-histological evaluation of positron emission tomography with18fluorodeoxyglucose (PET) positive mediastinal and hilar lymph nodes developed in patients with previous malignancies.

All EBUS-TBNA cases performed from January 2012 to May 2016 were retrospective reviewed. Results of EBUS-TBNA in patients with mediastinal and/or hilar lymphadenopathies were analysed. Non-malignant cytopathologies were confirmed with surgical procedures or clinical and radiological follow-up.

Among 1780 patients, 176 were included in the analysis. 103 of these (58.5%) had a diagnosis of tumour recurrence whereas 73 (41.5%) had a different diagnosis: 63 (35.8%) had a non-neoplastic diagnosis and 8 patients (4.6%) had a different cell type malignancy. Samples were false-negative in 5 (2.8%) out of 176 patients. The overall sensitivity, specificity, negative predicted value and diagnostic accuracy were 95.7% (95% CI 90.2–98.6%), 100% (95% CI 94.0–100%), 92.3% (95% CI 83.2–96.7%) and 97.2% (95% CI 93.5–98.8%), respectively.

EBUS-TBNA demonstrated a pathological diagnosis different from the previous tumour in a large percentage of patients, confirming its strategic role in the management of patients with previously treated malignancies.
The retromer, sorting nexins and the plant endomembrane protein trafficking
Authors: Heucken Nicole , Ivanov Rumen
Published: October 2017

Protein sorting in the endomembrane system is responsible for the coordination of cellular functions. Plant intracellular trafficking has its own unique features, which include specific regulatory aspects of endosomal sorting and recycling of cargo proteins, mediated by the retromer complex. Recent work has led to significant progress in understanding the role of Arabidopsis retromer subunits in recycling vacuolar sorting receptors and plasma membrane proteins. As a consequence, members of the sorting nexin (SNX) protein family and their interaction partners have emerged as critical protein trafficking regulators, in particular with regard to adaptation to environmental change, such as temperature fluctuations and nutrient deficiency. In this Review, we discuss the known and proposed functions of the comparatively small Arabidopsis SNX protein family. We review the available information on the role of the three Bin-Amphiphysin-Rvs (BAR)-domain-containing Arabidopsis thaliana (At)SNX proteins and discuss their function in the context of their potential participation in the plant retromer complex. We also summarize the role of AtSNX1-interacting proteins in different aspects of SNX-dependent protein trafficking and comment on the potential function of three novel, as yet unexplored, Arabidopsis SNX proteins.

Το άρθρο αυτό μελετά τις πολλαπλές συγκλίσεις δυο ετερογενών περιπτώσεων ιδεολογικού λόγου στην Ελλάδα της δεκαετίας του 1990 αλλά καί μέσα και ενάντια στις συνθήκες της υπό διαμόρφωση νέας παγκοσμιότητας. Παρακολουθώντας τον δημόσιο λόγο που διατυπώνουν το ΚΚΕ και η Ορθόδοξη Εκκλησία της Ελλάδας, διαπιστώνουμε καταρχήν την κοινή εκφορά ενός εθνικο λαϊκιστικου επιχειρήματος. Επιχείρημα που, στη συνέχεια, διασυνδέεται με μία παραδοσιοκρατική στροφή, συγκροτώντας έτσι το πεδίο διαμόρφωσης ενός λόγου αντιθετικού προς το κυβερνητικό εκσυγχρονιστικό πρόγραμμα, το οποίο, παράλληλα, συναντά τα όρια της δικής του εργαλειακότητας. Το άρθρο καταλήγει με τη διαπίστωση ότι οι συγκλίσεις των δύο υπό εξέταση φορέων επισυμβαίνουν στο έδαφος ενός αναδυόμενου συντηρητισμού ο οποίος επικαθορίζει κλασικές διχοτομίες του πολιτικού πεδίου (όπως Αριστερά-Δεξιά) και τελικά ευνοεί τη δημόσια παρέμβαση των παραδοσιακά συντηρητικών πολιτικών και κοινωνικών δυνάμεων, όπως εδώ η ορθόδοξη εκκλησία.

O shadowing é uma técnica de pesquisa qualitativa raramente utilizada na pesquisa em organizações. Essa técnica consiste no acompanhamento de uma pessoa durante o seu dia de trabalho, por um extenso período de tempo, no tempo de suas atividades e interações diárias, de modo a colher informações que são registradas no diário de campo, podendo, ainda, o pesquisador utilizar outros recursos. Neste artigo, o objetivo foi relatar a experiência da aplicação da técnica shadowing como modo de pesquisa no campo dos estudos organizacionais. Para tanto, registrou-se a experiência de uma das autoras no acompanhamento de um grupo de teatro com o objetivo de compreender o modo pelo qual as organizações são criadas e recriadas a partir das práticas constantes e do resultado de processos, o que contribui para o conhecimento sobre o modo como as organizações acontecem, e não como elas simplesmente são. Apresenta-se a experiência com a aplicação da técnica considerando as bases conceituais do shadowing, a fase da preparação, o acompanhamento e as recomendações práticas para a aplicação da técnica. Ao fazer isso, aponta-se para o potencial dessa técnica na contribuição da pesquisa organizacional.
Contribuições do Macromarketing para a Formação de Administradores – Podemos Melhorar o Ensino de Marketing em Cursos de Graduação em Administração?
Authors: Berardinelli Rodolfo Peres , Sauerbronn João Felipe Rammelt
Published: October 2017

A formação dos estudantes de administração no Brasil encontra-se centrada em aspectos gerenciais do marketing e, por conta disso, gestores parecem incapazes de lidar com a complexidade do sistema de trocas. Em um mundo no qual as vidas das pessoas passam a ser cada vez mais afetadas por mercados, torna-se fundamental ampliar a compreensão a respeito da disciplina que trata das relações entre mercados e sociedade: o macromarketing. No presente artigo, realizamos entrevistas em profundidade com nove professores de marketing de cursos de graduação de administração com o intuito de levantar suas visões acerca do ensino da disciplina, das suas lacunas, assim como seus entendimentos a respeito do macromarketing, seus conceitos e suas possíveis contribuições para a formação de futuros administradores. Os dados coletados trouxeram à tona três lacunas do ensino de marketing associadas à superficialidade de tratamento do conceito de mercado, à desconexão da disciplina com questões sociais e perspectivas locais e à visão acrítica do campo. As entrevistas, também, mostraram as potenciais contribuições do macromarketing para a melhoria da formação dos administradores por meio da inclusão de discussões sobre os sistemas de marketing, as consequências sociais do marketing e uma abordagem mais crítica da disciplina.

O presente artigo teve como objetivo apresentar os resultados de um estudo que buscou identificar o perfil dos artigos científicos em finanças publicados na Revista de Administração de Empresas (RAE) da Fundação Getulio Vargas de São Paulo (FGV/SP), no período de 2006 a 2016, com vistas a ampliar o conhecimento acerca da evolução da divulgação dos estudos científicos brasileiros na área. Para a realização deste artigo, foi executada uma pesquisa descritiva; quanto ao procedimento, foi de tipo bibliográfico e bibliométrico. A abordagem foi quantitativa. Para a organização e tabulação dos dados foi utilizado o software MS-Excel. Os resultados permitiram observar que a maioria dos artigos de finanças publicados pela RAE, durante o período analisado, foi produzida por profissionais brasileiros com doutorado, do gênero masculino, vinculados a instituições estabelecidas na região Sudeste, principalmente, a FGV e a USP. Observou-se, também, que houve uma grande variedade entre os temas de finanças abordados, com a predominância por temas voltados ao mercado financeiro e à gestão de grandes negócios, sendo que estudos sobre governança corporativa e mercado de capitais foram os mais publicados.
Poder, paradigmas e domínio na pesquisa em marketing no Brasil: uma análise da produção nacional da disciplina a partir das matrizes epistêmicas
Authors: Scussel Fernanda Bueno Cardoso
Published: October 2017

A literatura tem sinalizado a insuficiência da lógica paradigmática para estudar os fenômenos sociais abarcados pelo marketing, além de revelar a necessidade de amadurecimento da epistemologia desta disciplina. Com base nisso, recorreu-se às matrizes epistêmicas, uma abordagem alternativa para produção de conhecimento em estudos organizacionais, cuja aplicação ao marketing é apresentada e discutida neste trabalho. Destarte, este artigo ensejou articular um debate sobre as questões de poder, os paradigmas e o domínio dentro da pesquisa de marketing no Brasil, para tanto, apresentando os resultados de uma análise epistemológica que contemplou 311 artigos publicados no Encontro de Marketing da Anpad (EMA), nos últimos cinco anos. As informações extraídas dos artigos foram enquadramento do estudo e orientação epistemológica. Tal análise permitiu identificar os assuntos mais debatidos conceitualmente, as lógicas dominantes dos estudos empíricos e as perspectivas para desenvolvimento de investigações futuras. Entre os principais achados, destacaram-se a necessidade de construção teórica da disciplina, a emergência de estudos de orientação interpretativista e crítica e, ainda, o fortalecimento dos estudos multimétodo, que configuraram uma esperança à superação da dualidade das lógicas positiva e interpretativa, dessa forma, conduzindo o marketing ao estudo dos fenômenos em sua totalidade.

Diante das novas exigências que estão sendo colocadas para o Ensino Superior (oferecer formação condizente com as constantes transformações do mercado de trabalho), do papel da universidade na formação profissional discente (preparar o aluno para o exercício profissional, criando condições para integrá-lo, sem maiores dificuldades, no mercado de trabalho), da importância da prática do estágio (seja supervisionado ou não) na formação do estudante de administração e, sobretudo, da necessidade de ampliação da discussão sobre o tema, este artigo teve como objetivo analisar a atual situação dos estudos acadêmicos acerca do estágio em administração no Brasil. Para tanto foi realizada uma pesquisa bibliométrica na base de dados da SPELL e nos anais dos eventos da ANPAD, Semead e CIGU. Optou-se pela regra de exaustividade de Bardin (2011), não sendo definido corte temporal a priori para coleta de dados. Assim, foram recuperados 30 artigos, sendo 28 considerados válidos para compor o corpus deste estudo. As conclusões revelam que, mesmo diante da importância para a formação profissional do estudante de administração, há fragilidade nos estudos referentes ao estágio na área no Brasil: a discussão teórica sobre estágio, do ponto de vista pedagógico, é frágil e pouco profícua, significativamente recente, e sem avanços expressivos para a área.
Influence of Montmorillonite Nanoclay Content on the Optical, Thermal, Mechanical, and Barrier Properties of Low-Density Polyethylene
Authors: Bumbudsanpharoke Nattinee , Lee Wooseok , Choi Jae Chun , Park Se-Jong , Kim Meekyung , Ko Seonghyuk
Published: October 2017

Although low density polyethylene (LDPE) has long been widely used in packaging applications, some limitations in its use still exist and are due to its relatively poor gas barrier properties and low mechanical strength which can restrict its extensive use for more advanced applications, such as electronic and pharmaceutical packaging. The purpose of this study was to investigate the possibility of using montmorillonite (MMT) nanoclay as a means to enhance the thermal, mechanical, and barrier properties of LDPE prepared via melt extrusion. The level of exfoliated dispersion of the MMT nanoclay in the prepared LDPE-MMT composite was confirmed using transmission electron microscopy (TEM). The relationship between the resulting morphology and the thermal, mechanical, and barrier properties as a function of the MMT content was evaluated. The results showed that incorporating >3 wt.% of MMT nanoclay produced significant changes in the morphology of the LDPE-MMT nanoclay composite in that the segregated matrix adopted an oriented arrangement of exfoliated clay platelets. Thermogravimetric analysis (TGA) showed that the thermal stability of LDPE improved significantly as a result of MMT nanoclay incorporation. Furthermore, differential scanning calorimetry (DSC) analysis indicated that increasing clay content above 3 wt.% effectively reduces the crystallinity of LDPE-MMT composites through the suppression effect. The tensile strength of LDPE increased gradually with an increased content of MMT nanoclay and the maximum value of 16.89 N/mm2 was obtained at 10 wt.% MMT content. This value represents a 40.87% increase relative to the tensile strength of the pristine LDPE. Barrier properties of LDPE and LDPE-MMT nanoclay composites were assessed by examining the permeability with respect to oxygen and water vapor. As the content of MMT nanoclay was increased to 10 wt.%, the permeability of the nanocomposite films to oxygen and water vapor notably decreased to 42.8% and 26.2%, respectively.

Mehr denn je stehen die Kollegien der Öffentlichen Bibliotheken im Fokus: Digitalisierung und Automatisierung verändern die Berufsbilder und die Anforderungen an alle Mitarbeiter. Aufgeschlossen gegenüber Kunden und technischen Neuerungen sollen sie sein und bereit zur Weiterbildung. Personalentwicklung ist Thema in jedem Bibliothekssystem, insbesondere für die Berufsgruppe der FaMI, die für neue performante Aufgabenfelder qualifiziert werden. Doch auch neue Professionen tun den Bibliotheken und ihrer Programmarbeit gut. Ein Kollegium in Bewegung verändert die Organisation.
Bibliotheken ohne Bibliothekar/innen? Qualifikationen für die wissenschaftliche Bibliothek
Authors: Söllner Konstanze
Published: October 2017

Die bibliothekarische Ausbildung befindet sich im Umbruch – oder sie sollte sich zumindest im Umbruch befinden, denn die Anforderungen verändern sich. An wissenschaftlichen Bibliotheken bilden sich neue Aufgabenprofile für wissenschaftlich vorqualifizierte Bibliothekar/innen heraus, FaMIs jedoch werden oft weit unter ihrer Qualifikation eingesetzt. Gleichzeitig finden nur wenige IT-affine Bachelor-Studierende aus den bibliotheks- und informationswissenschaftlichen Studiengängen den Weg in die Bibliotheken. Grundständige Vermittlung der neuen Inhalte statt Häppchenkultur erfordert Mut, ist aber unausweichlich, wenn die Ausbildungswege robust bleiben sollen.
Bibliotheks- und informationswissenschaftliche Aus- und Weiterbildung: Herausforderungen und Perspektiven
Authors: Georgy Ursula
Published: October 2017

Die Entwicklung des Berufsbildes des Bibliothekars und Informationsspezialisten ist zahlreichen Veränderungen unterworfen, sodass auch die Hochschulen in ihren Studiengängen diese Veränderungen aufgreifen müssen. Die Hochschulen stehen im Kontext der Digitalisierung ebenfalls vor gravierenden Veränderungen hinsichtlich Lehr- und Lernformen sowie neuen Studieninhalten und Weiterbildungsangeboten. Durch ein systematisches Qualitätsmanagement, das sich z. B. am Prinzip von Swissuni orientiert, kann es gelingen, diese Herausforderungen zu meistern und die Bibliotheken bzw. ihre Mitarbeiter fit für die Zukunft zu machen.

Biblio… was studierst du?
Authors: Buhlmann Frauke Anna
Published: October 2017

Immer wieder werde ich gefragt, was ich studiere und warum. Zugegeben ist der Berufswunsch „Bibliothekarin“ bei einer 22-Jährigen nicht das, was man erwartet zu hören. Daher lässt sich die Frage nach dem „Warum“ auch nicht mit einem einfachen Satz beantworten. Vielmehr muss man einmal erleben, was es wirklich heißt in einer Bibliothek zu arbeiten, in der man jeden Tag anderen Menschen begegnet und wie es einen selber glücklich macht.

A review of internal corrosion mechanism and experimental study for pipelines based on multiphase flow
Authors: Zhang Hao , Lan Hui-qing
Published: October 2017

The internal corrosion of pipelines in the petroleum industry is highly risky, and induced pipeline cracking may give rise to potential injury to personnel and environmental issues. The oil-water two-phase flow and the oil-gas-water three-phase flow are often observed in gathering and transportation pipelines. It is generally accepted that corrosion is induced by the presence of water, although it is a complex hydrodynamic process in which the material is removed from the pipeline due to physicochemical reactions. Hence, it is necessary to determine the key parameters that dominate the corrosion phenomena and how they can be modeled. As the water phase that wets the steel surface determines the initiation of corrosion, several aspects are widely discussed here, such as corrosive medium, phase inversion, water-wetting behavior, the entrainment of water, and the wettability of steel, to explain the corrosion mechanism of multiphase flow and correlation with the corrosion behavior. Of course, empirical and mechanistic models for corrosion prediction in pipelines are discussed. Also, the mostly applied techniques of identifying flow patterns and attaining related parameters in experiments for the evaluation of the corrosiveness of oil-brine mixtures are introduced. Further studies must be undertaken to expand the knowledge of corrosion and find applicable models for corrosion damage prediction and prevention.
A Prima Facie Evidence on the Impact of Export Diversification on Relative Trade Preferential Margin
Authors: Gnangnon Sena Kimm
Published: October 2017

This paper assesses the impact of export diversification in developing countries and particularly Least developed countries (LDCs) on the relative preferential margin that they enjoy in accessing preference-granters’ market. The analysis is carried out in a gravity-type model comprising 19 developed countries and 54 beneficiaries of non-reciprocal trade preferences from these developed countries, over the period 2002–2007. The empirical analysis suggests a non-linear relationship between the degree of export diversification in developing countries and the relative preferential margin that they benefit from developed preference-granting countries. However, it appears that the latter encourage LDCs to diversify their export products by providing them with higher trade preference advantages compared to their competitors in their markets.
Characterization of moisture in acetylated and propionylated radiata pine using low-field nuclear magnetic resonance (LFNMR) relaxometry
Authors: Beck Greeley , Thybring Emil Engelund , Thygesen Lisbeth Garbrecht , Hill Callum
Published: October 2017

Moisture in radiata pine (Pinus radiataD. Don) earlywood (EW), which was acetylated or propionylated to various degrees, was measured by low-field nuclear magnetic resonance (LFNMR) relaxometry. Spin-spin relaxation times (T2) were determined for fully saturated samples at 22 and −18°C.T2values for EW lumen water increased with increasing acetylation weight percentage gain (WPG), perhaps caused by the less hydrophilic acetylated wood (AcW) surface. Cell wall water (WCW) and the water in pits and small voids also showed increasingT2values as a function of WPG but with a weaker tendency. A possible explanation is the counteracting effects of decreased hydrophilicity and reduced moisture content (MC) of these water populations at higher levels of acetylation. The evaluation of propionylation on WCWT2data was complicated by peak splitting in the relaxation spectrum. ConstantT2values for void water populations at various WPG levels for propionylated samples indicate a modification gradient in the cell wall. Fiber saturation point (FSP) was significantly reduced by both modifications. Slightly higher FSP values for propionylated samples suggest that physical bulking is not the only factor causing moisture exclusion in AcW. But this interpretation is tentative because of the possibility of cell wall damage caused by propionylation.
The Multinational State That Wasn’t: The Constitutional Definition of Romania as a National State
Authors: Suteu Silvia
Published: October 2017

This article looks at the constitutional label of Romania as a ‘national state’ and the constitutional discourse surrounding it. It argues that this label is unavoidably linked to a project of constitutional nationalism. The article examines the origins of the provision enshrining this state characteristic, as well as the eternity clause declaring it unamendable, so as to reconstruct the genealogy of the idea of the national state in Romania. The article traces the origins of the concept to early-twentieth century nation-building discourse but links its current incarnation to the distinctive type of nationalism promoted in late communist and early post-communist Romania and its fear of the Hungarian ‘other’. This fear seeped into debates in the 1990–1991 constituent assembly debating the new constitution, which proceeded to disregard calls for a more pluralist definition of the state and clearer constitutional protection for national minorities. While some of these choices were revisited during the 2003 revision of the constitution, the fundamental law retains its emphasis on the national state. To this day, Article 1 (1) continues to be contested, especially by representatives of the Hungarian community. At the same time, it is invoked and creates confusion every time administrative territorial reorganisation is entertained. The article argues that greater clarity is required in understanding the concept and operation of the national state provision, as well as openness to an inclusive national dialogue surrounding this constitutional unsettlement. Only by moving the constitutional discourse beyond the highly politicised debates of years past, and the ‘us versus them’ mentality informing them, can Romanian constitutionalism show a maturity in keeping with its recent 25-year anniversary.
