Evaluation of the anterior cervical angle of the uterus to predict spontaneous preterm birth
Authors: Sur Bijay , Misra Sujata , Dash Sanghamitra
Published: May 2017

Background: This prospective observational study was conducted to evaluate the anterior cervical angle (ACA) of the uterus by transvaginal sonography (TVS) and to determine the feasibility to predict spontaneous preterm birth (PTB). The duration of the study was from December 2014-December 2016.The participants included 100 pregnant women with singleton pregnancy who were asymptomatic. They were enrolled after excluding all known risk factors of preterm birth.Methods: The ACA and cervical length were measured in all cases by transvaginal sonography either in the 1st trimester or 2nd trimester. All cases were followed and well documented with respect to the gestational age at delivery.Results: There was a significant risk of preterm labour in women with cervical length <2.5cm in the 2nd trimester with Odds Ratio 3.625, P value=0.001, sensitivity 75% and specificity 79.31%. The positive predictive value was 33.33% and negative predictive value 95.83%. The false positive rate was 20.65% and false negative rate 25%. The difference of mean cervical angle in women who delivered preterm and that of those who delivered at term, in the 1st    trimester (preterm group 114.2°Vs term group 93.0°, P<0.001) and in the 2nd trimester (preterm group 127.66° Vs term group 103.65°, P <0.001) was significant. An ACA of 114.2° in the 1st trimester was associated with a risk of spontaneous preterm birth (P value 0.0065, sensitivity 90% and specificity 80%). An ACA of 127.66° in 2nd trimester was associated with a risk of spontaneous preterm birth (P value 0.0004, sensitivity 80%and specificity 88.23%).Conclusions: Despite the limitations of a small sample size, the results suggest that the anterior cervical angle has potential as a new predictor of spontaneous preterm birth especially when measured in the 1st trimester.

BERTA BRASLASKY (1913-2008): UNA MAESTRA, LA ESCUELA DE LA VIDA Y LOS ITINERARIOS PARA TRAMITAR SU OBSESIÓN POR LA EDUCACIÓN
Authors: Diamant Ana
Published: May 2017

La historia de Berta, es la de alguien que se ha rebelado - junto a su familia y compañeros de ruta - a circunstancias que hubieran obligado a un destino estrecho para argentinos no "predestinados" naturalmente a la escuela, a la que se sumaron socios de otras latitudes, algunos anfitriones de sus exilios, otros por la difusión de sus ideas, en la convicción de que la educación y sobre todo la lectura, no son un derecho sino una garantía de inclusión.

Con sus testimonios y los de familiares, colegas, discípulos, se recorre casi todo el S XX, desde los orígenes en una familia de inmigrantes judíos, el pasaje por la escuela rural, el traslado a la "gran" ciudad, la graduación como maestra, la actividad política y las persecuciones, la universidad, la formación de enseñantes, la gestión, siempre "militando" la alfabetización y la educación.

La vida, la condición de estudiante y de graduada, la profesión, los viajes, las adscripciones ideológicas, la acercaron tanto a las luchas populares como a las ideas de circulación internacional y sobre todo a las experiencias inspiradas en las utopías pedagógicas de la mano de Tolstoi y Makarenko, a las políticas de género desde su participación en 1948 en el I Congreso Internacional de Mujeres en Budapest, a la posibilidad de formarse en el Instituto de Psicobiología con Wallon, en hospitales europeos en los que conoce a Zazzo, Ajuriaguerra y Lebovici, a pensar en las diferencias de afrontar aprendizajes al tiempo que discutía la hegemonía médica en su tratamiento.

Desde Positivismo y Antipositivismo en Argentina (1952) pasando por La querella de los métodos (1962) hasta Primeras letras o primeras lecturas (2004) fortaleció la convicción de que no hay acto pedagógico aislado y que las dificultades escolares deben ser una razón de estado.
COEDUCACIÓN EN LA FORMACIÓN INICIAL DEL PROFESORADO: DE LA TRANSVERSALIDAD A LA VIVENCIA A TRAVÉS DE LA ÉTICA DEL CUIDADO
Authors: García-Cano Torrico María , Hinojosa Pareja Eva
Published: May 2017

Los planes de formación inicial del profesorado en las universidades españolas siguen adoleciendo de la incorporación de contenidos y metodologías sobre coeducación. El artículo, desde una perspectiva reflexiva de la actividad docente, presenta las oportunidades que la aplicación de una metodología particular aplicada como Proyecto de Mejora en los Grados de Infantil y Primaria en la Universidad de Córdoba, potencia y posibilita la formación de los y las estudiantes en contenidos vinculados a los principios que definen la ética del cuidado de Carol Gilligan. Se identifican y describen las líneas de investigación que se han producido en el ámbito de la formación inicial del profesorado desde la coeducación y se definen los principios del modelo educativo feminista de la ética del cuidado. La descripción de la propuesta metodológica que se viene desarrollando durante dos cursos académicos (2014/15 y 2015/16) sirve de referente para justificar los aportes que dicho proceso de enseñanza-aprendizaje tiene para la formación inicial coeducativa de maestros y maestras a través de la incorporación de elementos como la interdependencia, la comunicación, la responsabilidad y el cuidado.
Francuska czarownica czy angielska reformatorka? – postrzeganie Anny Boleyn przez wieki na podstawie wybranych źródeł i literatury
Authors: Paczkowska Ewa
Published: May 2017

Mimo że Anna Boleyn była Angielką, przez jej współczesnych była postrzegana jako Francuzka zarówno pod względem wykształcenia, jak i różnic kulturowych. Wprowadzone przez nią zmiany w zakresie religii, kultury, edukacji oraz polityki były niekiedy tak obce społeczeństwu, że była niejednokrotnie nazywana Francuzką, ladacznicą czy czarownicą. W artykule zostaną przedstawione opinie o Annie pochodzące ze źródeł spisywanych za jej życia, jak również późniejszych, aż do czasów współczesnych. Na ich przykładzie zostanie podjęta próba odpowiedzi na pytanie, kim była Anna Boleyn oraz w jakim stopniu przekazywane na przestrzeni wieków informacje na jej temat są prawdziwe.
Wojna polsko-szwedzka z lat 1626–1629 w pismach Stanisława Koniecpolskiego
Authors: Wachoń Szymon
Published: May 2017

W latach 1626–1629 Rzeczpospolita Obojga Narodów prowadziła wojnę z Królestwem Szwedzkim. Wojna ta była częścią szerszej realizacji znanej jako dominium Maris Baltici. Gustaw II Adolf, król Szwecji, szukając pretekstu do inwazji na południowe wybrzeże Bałtyku, posłużył się roszczeniami Zygmunta III do szwedzkiej korony. Na początku wojny król Zygmunt III Waza osobiście dowodził armią, jednak po serii porażek zmuszony został wezwać Stanisława Koniecpolskiego. Hetman Koniecpolski mimo młodego wieku był już doświadczonym dowódcą. Doświadczenie to zdobył walcząc zarówno z Kozakami, jak i Tatarami. Liczne potyczki na stepach Ukrainy zostały następnie wykorzystanie w walce ze Szwedami.W pismach Stanisława Koniecpolskiego ukazana jest sytuacja wewnętrzna Rzeczpospolitej w pierwszej połowie XVII w. W listach do króla i innych ważnych dygnitarzy państwowych Koniecpolski opisuje nie tylko sytuację militarną. W pismach tych widoczna jest wyraźna troska o dobro kraju. Hetman zdawał sobie sprawę z wewnętrznych problemów państwa, takich jak nieefektywny system poboru podatków i brak zainteresowania szlachty toczącą się wojną. Wrażliwy na te problemy informował o nich najważniejszych dostojników państwowych.
Nałęczów w przewodnikach uzdrowiskowych przełomu XIX i XX wieku
Authors: Kiełb Ewa
Published: May 2017

Artykuł dotyczy przewodników po Nałęczowie, które ukazały się na przełomie XIX i XX w. Stanowią one istotną część piśmiennictwa związanego z uzdrowiskiem, zwłaszcza że wśród nich znalazło się pierwsze wydawnictwo książkowe informujące o nowym zakładzie leczniczym na terenach należących niegdyś do Małachowskich. Oprócz przedstawienia danych o zawartości przewodników w artykule zestawiono analizowane teksty z tekstami o podobnym charakterze, które publikowano wówczas w Europie. Ponadto artykuł ukazuje, jak w okresie zaborów autorzy zaangażowani w działalność patriotyczną stosowali określone zabiegi językowe, by uniknąć zastrzeżeń ze strony rosyjskiej cenzury. Dzięki temu przewodniki z omawianego okresu mogły odegrać ważną rolę krajoznawczą, budując jednocześnie pozycję Nałęczowa na tle innych zakładów leczniczych.
Doktor Herta Oberheuser i jej działalność medyczna w KL Ravensbrück w świetle zeznań świadków i ofiar eksperymentów
Authors: Fronczak Paulina
Published: May 2017

Herta Oberheuser była jedyną kobietą-lekarzem skazaną podczas procesów lekarzy w Norymberdze. W czasie jej pracy w obozie koncentracyjnym w Ravensbrück wraz z innymi lekarzami, np. Karlem Gebhardtem czy Fritzem Fischerem, dokonywała eksperymentów na kobietach – zabiegi polegały na transplantacjach kości, a także na wprowadzaniu do ran m.in. bakterii, drewna i szkła, co miało oddać warunki panujące na froncie. Niemieccy lekarze chcieli znaleźć sposób na zahamowanie powszechnego zjawiska i sposobu wyleczenia zakażenia w warunkach polowych. Przyczynkiem do nieludzkich badań był zamach na szefa Głównego Urzędu Bezpieczeństwa Rzeszy (RSHA) – Reinharda Heydricha w roku 1942 i jego śmierć wskutek zgorzeli gazowej. W artykule przedstawione są wspomnienia operowanych kobiet oraz świadków w procesie norymberskim. W relacjach osób mających bezpośredni kontakt z lekarką jawi się ona jako osoba bezwzględna, okrutna, służąca wyższej idei, pozbawiona jakichkolwiek ludzkich odruchów i uczuć. Wzbudzała ona postrach, każda z więźniarek obawiała się spotkania z asystentką doktora Gebhardta.
Doświadczenie w narracjach nauczycieli – imperatyw w formowaniu tożsamości dojrzałej
Authors: Popek Katarzyna
Published: May 2017

Głównym założeniem moich badań dotyczących samodoskonalenia nauczycieli, na podstawie ich doświadczeń zawodowych oraz związanych z realizacją powołania, jest ukazanie złożoności i zarazem niejednoznaczności charakteru nauczyciela we współczesnym świecie. Wyzwaniem, jakie podejmuję, jest wypracowanie odpowiedniej metodologii, pozwalającej ująć i opisać wpływ życiowego doświadczenia na formowanie się dojrzałej tożsamości osobowej wśród nauczycieli. Prezentowana praca jest zalążkiem „wykuwania się” tych sposobów ujęcia szczególnego rodzaju doświadczeń, o których piszę; tak też jest w przypadku badania każdej szczególnej egzystencji w nadziei na wydobycie konkretnych treści. Okazuje się, że badane osoby: nauczycielka szkoły średniej, nauczyciel akademicki i nauczyciel duchowny są niezwykle oddane swojej misji służenia radą i pomocą, szczególnie zaś właściwym inspirowaniem swoim przykładem. Najważniejszym wnioskiem, jaki płynie z moich badań, jest stwierdzenie, że każdy prawdziwy nauczyciel jest przede wszystkim indywidualną jednostką ze swą osobistą historią i z doświadczeniami, których nie sposób generalizować.
Antoni Kępińskis „Informationsmetabolismus“ und Niklas Luhmanns „Autopoiesis“. Zwei Begriffe – ein Konzept?
Authors: Steger Florian , Schochow Maximilian
Published: May 2017

Die Konzepte „Informationsmetabolismus“ von Antoni Kępiński und „Autopoiesis“ von Niklas Luhmann rekurrieren auf die Struktur biologischer Zellen. Beide Autoren übertragen diese biologischen Strukturen auf ihre jeweiligen Anwendungsfelder. Während Kępiński die Funktionsweise der Psyche zu bestimmen sucht, integriert Luhmann den biologischen Ansatz in seine Systemtheorie der lebenden und psychischen Systeme. Bei der Lektüre von Kępińskis und Luhmanns Arbeiten wird deutlich, dass beide Autoren das Verhältnis zwischen einerseits Psyche und andererseits psychischem System mit ihrer jeweiligen Umwelt näher bestimmen. In Luhmanns Werk ist das Verhältnis zwischen System und Umwelt umfangreich beschrieben und ausgearbeitet. Vor diesem Hintergrund werden seine Ausführungen im Folgenden verwendet, um Kępińskis Überlegungen zum „Informationsmetabolismus“, dem Verhältnis von Psyche und Umwelt, zu reflektieren.
Anthropologische Psychiatrie. Eine Referenz der Kępiński-Rezeption?
Authors: Reuster Thomas
Published: May 2017

Es scheint naheliegend zu sein, Antoni Kępiński im Umkreis der so genannten Anthropologischen Psychiatrie zu verorten. Dafür sprechen in erster Annäherung seine Kritik der psychiatrischen Objektivität, sein persönlich engagierter Psychotherapiestil, und seine Annahme der konstitutiven Wertebestimmtheit des psychisch gesunden und kranken Menschen entsprechend der Vorgabe seines Modells des Informationsmetabolismus. Der Beitrag benennt zentrale Kriterien dieser psychiatrischen Arbeits- und Forschungsrichtung in Abgrenzung zur Humanistischen Psychologie. Er kommt zum vorläufigen Schluss, dass eine Identifikation Kępińskis mit der Anthropologischen Psychiatrie nicht gerechtfertigt wäre. Hingegen ist ein allgemeines, weiter gefasstes Konzept von anthropologischer Psychiatrie in der Lage, Kępińskis wesentliche Positionen zwanglos zu integrieren.
LOCAL WISDOM AND NATURAL DISASTER IN WEST SUMATRA
Authors: Rozi Syafwan
Published: May 2017

Community-based disaster management is an attempt to optimize the potential of social and local values in communities to facilitate the handling of natural disasters. West Sumatra as one of the disaster-prone areas in Indonesia has a number of local wisdom values—a value combining religion and local culture—rooted in traditional philosophy; “Adat Basandi Syara’, Syara’ Basandi Kitabullah”. The examples of those local wisdoms are customary ideas or proverbs in the form of legend and expressions, architectural design of the traditional house—“Rumah Gadang”—and the structure of the environment as well as the social systems of kinship and traditional administration in the form of Nagari. This research employed qualitative method by using ethnography approach. The data were collected through observations, participation in social events, and in-depth interviews. Those techniques were applied to obtain the valid information and the meaning of events and behaviors comprehensively. The local values applied by the indigenous communities as the victims of natural disasters in some regions of West Sumatra include “Badoncek” tradition in Nagari Tandikat Padang Pariaman, the architecture of “Rumah Gadang” in Nagari Sungayang, Tanah Datar and disaster mitigation based on district in Nagari Kubang Putiah Agam.

Managemen bencana berbasis masyarakat merupakan upaya untuk mengoptimalkan potensi sosial dan nilai-nilai lokal yang dimiliki masyarakat untuk memudahkan proses penanganan bencana alam. Sumatera Barat sebagai salah satu daerah rawan bencana di Indonesia, memiliki sejumlah nilai kearifan lokal, sebuah nilai yang memadukan antara agama dan budaya lokal yang termaktub dalam filosofi adat; Adat Basandi Syara’, Syara’ Basandi Kitabullah. Di antara kearifan lokal itu adalah ide atau pepatah adat dalam bentuk tambo dan ungkapan-ungkapan, tata ruang rumah adat dari segi arsitektur rumah gadang dan penataan lingkungannya serta sistem sosial kekerabatan dan pemerintahan adat dalam bentuk nagari. Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografi. Pengumpulan data dilakukan melalui observasi, keterlibatan dalam kegiatan masyarakat dan wawancara mendalam. Teknik-teknik ini dilakukan untuk mendapat informasi yang valid dan mendalam serta menghayati makna atau arti peristiwa dan tingkah laku secara komprehensif. Adapun nilai-nilai kearifan lokal yang diterapkan komunitas adat di Sumatera Barat meliputi tradisi badoncek di Nagari Tandikat Padang Pariaman, arsitektur dan tata kelola rumah gadang di Nagari Sungayang Tanah Datar serta mitigasi bencana berbasis nagari di Nagari Kubang Putiah Kabupaten Agam.

Inovação e geração de conhecimento científico e tecnológico no Brasil: uma análise dos dados de cooperação da Pintec segundo porte e origem de capital
Authors: Bastos Carlos Pinkusfeld , Britto Jorge
Published: May 2017

Este artigo tem como objetivo central a avaliação quantitativa das relações cooperativas desenvolvidas entre a estrutura produtiva brasileira envolvida com atividade inovativa, universidades e centros tecnológicos. A análise aborda essas relações tanto em termos de sua evolução no tempo como segundo características específicas das empresas, tais como porte e origem de capital. O trabalho empírico utiliza tabulações especiais da Pesquisa de Inovação (Pintec), realizada pelo Instituto Brasileiro de Geografia e Estatística (IBGE). As evidências apresentadas reforçam a constatação de que esse padrão de interação é bastante complexo e multifacetado, confirmando que variáveis como porte e origem de capital têm impacto relevante sobre a intensidade das relações de cooperação. Na análise temporal constatou-se uma perceptível melhoria dos indicadores que apontam para intensificação de práticas cooperativas na última Pintec (2011). Ainda que outros fatores, tanto micro como macroeconômico, conjunturais devam ser considerados, sugere-se que essa tendência pode representar um vetor positivo no que se refere às perspectivas de desenvolvimento da indústria brasileira.

Authors: Vieira Vinícius , Resende Marcelo
Published: May 2017

O artigo pretende avaliar os regimes tecnológicos no contexto da indústria brasileira de transformação, ao longo do período de 2000-2005. As indústrias foram classificadas em termos dos regimes tecnológicos Schumpeter Mark I (SM-I) e Schumpeter Mark II (SM-II), por meio de métodos de estatística multivariada baseados em variáveis que aproximam oportunidades tecnológicas, apropriabilidade, cumulatividade e base de conhecimento. A evidência indicou contrastes destacados na classificação relativamente às evidências anteriores para países desenvolvidos. Em particular, os setores farmacêutico e de papel e celulose possuem algumas especificidades no caso brasileiro. Os contrastes entre setores SM-I e SM-II para a totalidade de empresas indicaram diferenças significativas no caso de duas hipóteses: a participação de firmas pequenas é maior em indústrias SM-I do que naquelas SM-II; e as taxas de lucro são menores em indústrias SM-I do que nas SM-II.

Published: May 2017

In this paper new upper limits on the parameters of the Continuous Spontaneous Localization (CSL) collapse model are extracted. To this end the X-ray emission data collected by the IGEX collaboration are analyzed and compared with the spectrum of the spontaneous photon emission process predicted by collapse models. This study allows to obtain the most stringent limits within a relevant range of the CSL model parameters, with respect to any other method. The collapse rate $\lambda$ and the correlation length $r_C$ are mapped, thus allowing to exclude a broad range of the parameter space.

We report magnetic silver nanoshells (M AgNSs) that have both magnetic and SERS properties for SERS-based detection. The M AgNSs are composed of hundreds of Fe3O4 nanoparticles for rapid accumulation and bumpy silver shell for sensitive SERS detection by near-infrared laser excitation. The intensity of the SERS signal from the M AgNSs was strong enough to provide single particle-level detection. We obtained much stronger SERS signal intensity from the aggregated M AgNSs than from the non-aggregated AgNSs. 4-Fluorothiophenol was detected at concentrations as low as 1 nM, which corresponds to 0.16 ppb. The limit of detection for tetramethylthiuram disulfide was 10 μM, which corresponds to 3 ppm. The M AgNSs can be used to detect trace amounts of organic molecules using a portable Raman system.
Lévy Statistics and Glassy Behavior of Light in Random Fiber Lasers
Authors: De Araújo Cid B. , Gomes Anderson S. L. , Raposo Ernesto P.
Published: May 2017

The interest in random fiber lasers (RFLs), first demonstrated one decade ago, is still growing and their basic characteristics have been studied by several authors. RFLs are open systems that present instabilities in the intensity fluctuations due to the energy exchange among their non-orthogonal quasi-modes. In this work, we present a review of the recent investigations on the output characteristics of a continuous-wave erbium-doped RFL, with emphasis on the statistical behavior of the emitted intensity fluctuations. A progression from the Gaussian to Lévy and back to the Gaussian statistical regime was observed by increasing the excitation laser power from below to above the RFL threshold. By analyzing the RFL output intensity fluctuations, the probability density function of emission intensities was determined, and its correspondence with the experimental results was identified, enabling a clear demonstration of the analogy between the RFL phenomenon and the spin-glass phase transition. A replica-symmetry-breaking phase above the RFL threshold was characterized and the glassy behavior of the emitted light was established. We also discuss perspectives for future investigations on RFL systems.
Application of Synthetic Layered Sodium Silicate Magadiite Nanosheets for Environmental Remediation of Methylene Blue Dye in Water
Authors: Mokhtar Mohamed
Published: May 2017

The removal of methylene blue (MB) dye from water was investigated using synthetic nano-clay magadiite (SNCM). SNCM was synthesized by hydrothermal treatment under autogenous pressure. A rosette-shaped single mesoporous magadiite phase with 16.63 nm average crystallite size and 33 m2.g-1 BET-surface area was recorded. The adsorption results indicated the pronounced affinity of the SNCM to the MB dye molecules which reached adsorption uptake of 20.0 mg MB dye/g of SNCM. The elimination of MB dye by the SNCM was kinetically and thermodynamically considered; a pseudo second order kinetic model was attained, and a spontaneous, chemical, and exothermic in nature was verified.

Authors: Hebert-Davies Jonah , Teefey Sharlene A. , Steger-May Karen , Chamberlain Aaron M. , Middleton William , Robinson Kathryn , Yamaguchi Ken , Keener Jay D.
Published: May 2017

Background:

The purpose of this prospective study was to examine the progression of fatty muscle degeneration over time in asymptomatic shoulders with degenerative rotator cuff tears.

Methods:

Subjects with an asymptomatic rotator cuff tear in 1 shoulder and pain due to rotator cuff disease in the contralateral shoulder were enrolled in a prospective cohort. Subjects were followed annually with shoulder ultrasonography, which evaluated tear size, location, and fatty muscle degeneration. Tears that were either full-thickness at enrollment or progressed to a full-thickness defect during follow-up were examined. A minimum follow-up of 2 years was necessary for eligibility.

Results:

One hundred and fifty-six shoulders with full-thickness rotator cuff tears were potentially eligible. Seventy shoulders had measurable fatty muscle degeneration of at least 1 rotator cuff muscle at some time point. Patients with fatty muscle degeneration in the shoulder were older than those without degeneration (mean, 65.8 years [95% confidence interval (CI), 64.0 to 67.6 years] compared with 61.0 years [95% CI, 59.1 to 62.9 years]; p < 0.05), and the median size of the tears at baseline was larger in shoulders with degeneration than in shoulders that did not develop degeneration (13 and 10 mm wide, respectively, and 13 and 10 mm long; p < 0.05). Tears with fatty muscle degeneration were more likely to have enlarged during follow-up than were tears that never developed muscle degeneration (79% compared with 58%; odds ratio, 2.64 [95% CI, 1.29 to 5.39]; p < 0.05). Progression of fatty muscle degeneration occurred more frequently in shoulders with tears that had enlarged (43%; 45 of 105) than in shoulders with tears that had not enlarged (20%; 10 of 51; p < 0.05). Additionally, tears with enlargement and progression of muscle degeneration were more likely to extend into the anterior supraspinatus than were those without progression (53% and 17%, respectively; p < 0.05); however, this relationship was lost when controlling for tear size (p = 0.56). The median time from tear enlargement to progression of fatty muscle degeneration was 1.0 year (range, −2.0 to 6.9 years) for the supraspinatus and 1.1 years (range, −1.8 to 8.5 years) for the infraspinatus muscle (p = 0.98).

Conclusions:

Progression of fatty muscle degeneration is more common in tears that are larger at baseline, enlarge over time, and undergo a larger magnitude of enlargement. Our study findings also suggest that an often rapid progression of muscle degeneration occurs in relation to a clinically relevant increase in tear size in some degenerative cuff tears.

Implant Survival After Minimally Invasive Anterior or Anterolateral Vs. Conventional Posterior or Direct Lateral Approach
Authors: Mjaaland Knut Erik , Svenningsen Svein , Fenstad Anne Marie , Havelin Leif I. , Furnes Ove , Nordsletten Lars
Published: May 2017

Background:

Since 2008, there has been an increase in the use of minimally invasive surgery (MIS) through an anterior or anterolateral approach for total hip arthroplasty (THA) in Norway. We compared the MIS approaches with the conventional posterior and direct lateral approaches in terms of revision rates and risk of revision.

Methods:

On the basis of data in the Norwegian Arthroplasty Register, 21,860 THAs with an uncemented stem, performed between 2008 and 2013, were identified and included in the cohort. Of these THAs, 2,017 were done through an MIS anterior approach; 2,087, through an MIS anterolateral approach; 5,961, through a posterior approach; and 11,795, through a direct lateral approach. Follow-up ended on December 31, 2015. Two and 5-year survival rates were calculated using Kaplan-Meier survival analysis. Relative risk (RR) was calculated using Cox regression analysis, with adjustment for age, sex, primary diagnosis, American Society of Anesthesiologists (ASA) grade, femoral head size, cup fixation, type of articulation, and duration of surgery and using 6 revision end points based on cause: any cause, infection, dislocation, femoral fracture, aseptic loosening, and other/unknown cause. The median duration of follow-up was 4.3 years.

Results:

There were no significant differences among the surgical approaches with regard to the 2 and 5-year survival rates or RR of revision due to any cause. The RR of revision due to infection was 0.53 (95% confidence interval [CI] = 0.36 to 0.80, p = 0.002) for the MIS anterior and anterolateral approaches and 0.57 (95% CI = 0.40 to 0.80, p = 0.001) for the posterior approach compared with the direct lateral approach. The RR of revision due to dislocation was 2.1 (95% CI = 1.5 to 3.1, p < 0.001) for the posterior approach compared with the direct lateral approach but no significant difference in risk was found when the MIS anterior and anterolateral approaches were compared with the direct lateral approach (RR = 0.71, 95% CI = 0.40 to 1.3, p = 0.25).

Conclusions:

The revision rates and risk of revision associated with the MIS anterior and anterolateral approaches were not increased compared with those of the conventional posterior and direct lateral approaches.

The intention of the framework is to assess and encourage teaching excellence across English, Welsh, Scottish and Northern Ireland’s higher education institutions.The research presented – paints a picture of positives and negatives of the TEF as it is currently structured. The balance of evidence points to some serious flaws in the assessment of teaching quality proposed: For example, how can an initial institutional gold, silver or bronze award adequately reflect the diversity of quality across a university’s administration, admissions, student support, different departments and disciplines?The author also argues that the TEF emphasis on particular measures – such as employability and student achievement of professional jobs within 6 months of graduation – act against the wider social purposes of universities; and – in the words of Michael Oakeshott (1950: 30)  – diminish students’ search for their “intellectual fortune”.
Quality teaching through openness and collaboration – an alternative to the TEF?
Authors: Nerantzi Chrissi
Published: May 2017

In this opinion piece, I offer an alternative vision to the TEF that positions universities at the heart of communities and society through greater collaboration among higher education institutions and involving the public. I argue that this approach is a rewarding way for academic staff to develop their teaching capabilities and innovate, to improve the student taught experience at universities. Using measures such engagement in professional development and innovations in teaching as a result of it that have an impact on student learning, is my alternative to the TEF.
The Teaching Excellence Framework: Perpetual Pedagogical Control in Postwelfare Capitalism
Authors: Heaney Conor , Mackenzie Hollie
Published: May 2017

In this paper, we argue that Success as a Knowledge Economy, and the Teaching Excellence Framework, will constitute a set of mechanisms of perpetual pedagogical control in which the market will become a regulator of pedagogical possibilities. Rather than supporting pedagogical exploration, or creating conditions for the empowerment of students and teachers, such policies support the precarisation and casualisation of both. We develop these claims through a reading of these policies alongside Gilles Deleuze’s Postscript on the Societies of Control, and situating it in the context of what Gary Hall has termed postwelfare capitalism. We conclude by reaching out to others in the tertiary education sector and beyond to ask if this really is the direction we wish to take this sector in the UK.

Authors: Durand Laure , Genovez Victoria , Araujo Denizar
Published: May 2017

Objective: To define the economic value of a tetravalent dengue vaccine in Brazil by estimating the cost-effectiveness vaccine price threshold per dose. Methods: A dengue dynamic transmission model was used to estimate the public health impact of dengue vaccination and related economic parameters. Two vaccination strategies were assessed: routine vaccination at 9 years old plus ei[1]ther a catch-up campaign of 7 cohorts (10 to 16 years old; R9&10-16) or 16 cohorts (10 to 25 years old; R9&10-25). Brazilian-specific demographic, epidemiological and economic data were used. The economic impact over 10 years was estimated from the public payer and societal perspectives. All costs were expressed in BRL2016. Results: Over 10 years, the R9&10-16 and R9&10-25 vaccination strategies would prevent 9 million and 15 million dengue cases, respectively, avoiding 269,906 (95% CI: 410,097–154,653) and 434,334 (95% CI: 547,052–304,799) disability-adjusted life years. This would result in savings of up to BRL7.4 billion (US$2.1 billion) from a societal perspective with the larger vaccination program. The cost-effective vaccine price threshold per dose for the R9&10-16 and R9&10-25 strategies would be BRL187.5 (95% CI: 109–276) (US$52.1) and BRL183.6 (95% CI: 129–230) (US$51.0), respectively, from the public payer perspective, and BRL221.5 (95% CI: 129–326) (US$61.5) and BRL216.8 (95% CI: 153–271) (US$60.2), respectively, from the societal perspective. Conclusion: The high threshold of vaccine price per dose demonstrates the significant economic value of dengue vaccination in Brazil, even for a large program with 16 catch-up cohorts.

Estimation of Tight Gas Reserves During the Transient Flow Using a Modified GPA Method
Authors: Jimenez E. T. , Cervantes R. , Magnelli D. , Huerta V. A.
Published: May 2017

Scenarios of low permeability and long transient flow periods present in tight gas reservoirs, set out a major challenge on the reserves estimations. Consequently, these cause high uncertainties in volumetric estimates of gas (OGIP) and impacts in the deployment of technical and economic strategies in most projects.

Flowing material balance equation and decline curve techniques in tight gas reservoirs, have serious drawbacks to predict the original gas in place (OGIP). However, both techniques combined yield better modeling results, as shown by Cox et. Al. The aim of the present research is to propose a method based on the Gas Production analysis (GPA) technique with the Palacio & Blasingame approximations in conjunction with pressure transient analysis for diagnostics specialized of Linear Flow, which improve the confidence in reserve estimations, specifically in early time production.

The proposed method was applied in Lajas Formation of Neuquen Basin, Argentina, where a 20% maximum error decrease is expected in the OGIP, compared with non-type curve methods to the procedures (Hyperbolic and Exponencial model) in early time production.

When permeability and porosity values are higher, the error of this methods increases. This is mainly due to the fact that infinite acting flow periods are shorter. However, in low permeability scenarios the OGIP estimation may achieve acceptable outcomes since infinite acting flow last longer.
The effect of longevity risks on the performance of stock market
Authors: Choi Hyung-Suk
Published: May 2017

In this study the author examines the effect of the speed of population aging on the financial markets in 11 OECD (The Organisation for Economic Co-operation and Development) countries after controlling the proportion of labor population, the growth rate of real GDP (Gross Domestic Product), the rate of increasing productivity, inflation rate, and the rate of increasing scale of pension market. The author finds that the performance of stock market is affected by complex factors including increasing of average life expectancy, the growth rate of real GDP, the rate of increasing productivity, the inflation rate, the earning rate of stock market and the rate of increasing scale of pension market. Especially, the proportion of economically active people is the most significant factor to explain the stock market performance. Considering the decreasing proportion of economically active people in aging societies, the decrease of productivity and eventually the decrease of earnings from financial markets would be expected.

Agricultural enterprises in Ukraine require a considerable investment income. The paper studies the main problems and conditions for investment into agricultural enterprises, the scope and dynamics of their investment provision.
The results of agricultural enterprises activity depend directly on the state of their fixed assets. This is one of the biggest vulnerabilities of agricultural enterprises, which makes it impossible for the economy of Ukraine to demonstrate decent results. Investments should be used primarily for the development of material and technical basis of agricultural enterprises, because the fixed assets always depreciate, the term of their use in many enterprises exceeds 15 years and their number is constantly decreasing.
Investment in technical provision of plant growing is necessary and attractive. Firstly, as a basis of plant growing, grain and oilseeds are always in demand at the domestic and foreign markets. Secondly, the volumes of investments are moderate compared to other investments in agriculture. In the beginning, it is sufficient to invest into the branch on average from 1 to 2 thousand US dollars per 1 hectare. The average payback period of investments is 2-4 years.
Thus, in order to stimulate investments, it is vital to form a qualitatively new policy aimed at increasing investment attractiveness of agricultural enterprises.
Valuing synergies in strategic mergers and acquisitions using the real options approach
Authors: Loukianova Anna , Nikulin Egor , Vedernikov Andrey
Published: May 2017

The purpose of the current paper is to elaborate the model for assessing cumulative synergetic effect in M&A (Mergers and Acquisitions) deals on the basis of a real options approach. The majority of papers on the synergetic effects of M&A deals typically focus on a particular type of synergy, while the current paper proposes a model that accounts for the cumulative simultaneous effect of different types of operating and financial synergies. The methodology of our research is loosely based on Datar-Mathews real option valuation model, which is flexible and intuitive for practitioners. Formulae for assessing eight types of synergy typically arising from M&A deals are developed. They are integrated into a single model to assess their cumulative effect on the M&A deal using a simulation modelling approach. The method was used ex post to find synergy values in two recent M&A deals in the pharmaceutical industry, and produced sound results. The proposed approach to value target companies could be used by firms before an M&A deal in the due diligence process. Using this tool a company can build a bidding strategy and define the maximum premium it can pay for the target.
Pes Anserinus Syndrome Caused by Osteochondroma in Paediatrics: A Case Series Study
Authors: Sakamoto Akio , Matsuda Shuichi
Published: May 2017

Introduction:

Osteochondroma is a common benign bone tumor, protruding from the underlying normal bone. Osteochondromas can cause pain depending on their location and size. The pes anserinus is located at the proximal medial side of the tibia, where the tendinous insertions of the sartorius, gracilis and semitendinosus muscles collectively attach. Pes anserinus syndrome, or anserine bursitis, is a painful condition of the pes anserinus, and is more common in adults typically with overweight females. The occurrence of pes anserinus syndrome is rare in the paediatric population.

Results:

In the current case series, five patients with pes anserinus syndrome due to proximal tibial osteochondroma are reported. Pain was present in all cases, with snapping in one case. The average age of the patients was 13 ± 1.2 years, ranging from 12 to 15 years. Three patients had a single osteochondroma, and two patients had hereditary multiple exostoses. The sizes of the osteochondromas on plain radiographs varied from 0.5 to 2.5 cm, with an average of 1.46 ± 0.83 cm. All lesions characteristically were located at the medial-posterior edge of the proximal tibia. The symptoms resolved in four cases with surgical resection, and persisted in one non-resected patient.

Conclusion:

The characteristic location of the osteochondroma causes pes anserinus syndrome, even though the lesion is small. The diagnosis of osteochondroma or pes anserinus syndrome may be overlooked when it occurs in a paediatric population. The symptoms seem to be consistent, and resection of the osteochondroma is necessary for treatment.
