Published: January 2018

Canines are important teeth which are positioned at the corner of the mouth. Their development and eruption is a fascinating process because they move a long way towards the occlusal plane. In this presentation, the normal development of canines will be outlined. Furthermore, reasons for canine impaction will be discussed and the different methods of diagnosis using classic and modern methods such as Cone Beam CT Scans. Furthermore, different treatment options e.g. monitoring, interceptive extraction of primary teeth and exposure and orthodontic traction will be thoroughly explained. Moreover, the evidence behind each treatment option will be examined. Several cases treated by the presenter will be shown.
Przemysław Lazarowicz, Wymuszone dojrzewanie
Authors: Kowal Grzegorz 
Published: December 2017

In his narrative, Przemysław Lazarowicz (born 1st July 1964 in Wrocław), who as a teenager was an anticommunist oppositionist, tells us about his antigovernmental activity and his ernment under martial law in Poland.
He gives a detailed account of his role in a circle of people focused around Kornel Morawiecki, about the circumstances of his internment, his stay in the Provincial Citizens’ Militia at Podwale street in Wrocław, and about being interned in an isolation centre in Grodków. He also devotes a lot of attention to the conditions in which he lived while interned, characterizes some of the internees and describes their mutual relations, as well as rules according to which the centre was run and forms of resistance. A separate part of the narrative describes how Lazarowicz’s XIV LO (secondary school) friends and teachers reacted to the fact that he had been interned.
Podróż do Mezeritch. O doświadczeniu historii mówionej
Authors: Stolarz Agata 
Published: December 2017

What makes oral history different from any other history research method is the fact that a historian is actively involved in gathering information about events from the past. A category of performance borrowed from anthropology and ethnology shows that not only may a researcher influence a person narrating their story (e.g. by asking particular questions), it is also the storyteller who may influence the researcher, both in an existential as well as an epistemological dimension. The article discusses the problem of oral history research experience on the basis of an interview that the author carried out with the eighty-three-year old Kazimierz on the topic of the history of Międzyrzec Podlaski. The author presents the influence this interview had on her practicing oral history method as well as the history itself in a wider context.
A reflection on the experience of oral history understood as a kind of research intuition (J. Huizinga) and a form of experiencing a research situation (F. Ankersmit), allows for a closer look at the issue of a researchers’ self-awareness and as a result on factors influencing their way of gathering information and the process of constructing history narration.
„Libańczycy” i ich losy w perspektywie biograficznej
Authors: Gałęziowski Jakub 
Published: December 2017

The text is about Poles who in 1941, as a result of the so-called amnesty, left the Soviet Union and wandered the earth to end up in Lebanon. Their presence in this country was a phenomenon unprecedented in the Middle East region. The biggest wave of Polish refugees came to Lebanon in the years 1943–1946 and had ca. 6000 people for whom Lebanon became a truly safe haven. This continued till the beginning of the 1950s, when the last group off Poles left the country. Most of them never came back to their home country, settling mostly in Great Britain and beyond the Ocean, while only a handful of them remained in Lebanon.
The text discusses the accounts given by the so-called “Lebanese”, as those Poles who at some point of their lives found refuge in Lebanon call themselves. The accounts were recorded in Poland, Great Britain and Lebanon. “The Lebanese” explained the motives that drove people or their families forced to leave their place of stay when taking decisions regarding new destination. Also, the text describes in detail the impressions of the narrators from the new places they found themselves in and how they coped in new reality (on the example of Great Britain and Poland which was a Communist-ruled country at that time). The text aims to familiarize the audience with this subject, about which not much has been said so far.

Perilaku pencarian informasi (information seeking behaviour) merupakan perilaku pencarian tingkat mikro, yang ditunjukkan seseorang ketika berinteraksi dengan semua jenis sistem informasi. Pencarian informasi sangat dipengaruhi oleh kebutuhan informasi yang diinginkan oleh pengguna, semakin tinggi kebutuhan terhadap informasi yang diinginkannya, maka semakin tinggi pula pencarian informasi yang dilakukan oleh pengguna perpustakaan. Hal ini didukung oleh kebutuhan aktulisasi diri (dalam hal ini informasi).
Di dunia akademik, guru besar atau profesor adalah jabatan tertinggi bagi dosen yang mengajar di sebuah perguruan tinggi. Orang-orang yang menyandang gelar profesor merupakan orang yang luar biasa dan dengan usaha yang luar biasa pula yang dapat menyandang gelar tersebut.
Para guru besar dituntut melakukan kajian-kajian maupun penelitian di bidang spesialisasi yang mereka ambil. Oleh karena itu, mereka memerlukan akses terhadap informasi-informasi terkini dan pengetahuan-pengetahuan terbaru di bidang keahlian mereka ataupun bidang lain yang berkaitan dengannya. Informasi tersebut dapat diakses secara manual maupun online. Namun tidak semua guru besar dapat menelusur informasi yang dibutuhkannya, apalagi kalau informasi tersebut harus ditelusur secara online atau database. Oleh karena itu, tentu diperlukan strategi dalam memenuhi kebutuhan informasi mereka tersebut.
Hypoxic-ischemic brain injury: Planned delivery before intrapartum events
Authors: Odd David , Heep Axel , Luyt Karen , Draycott Tim 
Published: December 2017

BACKGROUND: Mothers are increasingly given greater control over many of the choices around birth, although there is little robust evidence to inform these choices. After an infant is born with HIE the question of whether it was predictable, or preventable, is often raised. Intrapartum ‘sentinel’ events and antenatal predictors of HIE have been well described, however there is little evidence how antenatal and intrapartum factors interact. This is particularly important when elective delivery by lower segment caesarean section (LSCS) has been shown to be beneficial in high risk groups. AIM: To develop a clinical risk score to identify women with a higher risk of having an infant with HIE. PATIENTS AND METHODS: This study is based on the Avon Longitudinal Study of Parents and Children (ALSPAC). This dataset was split into two halves: with each infant being randomly allocated to either cohort one or two. The first cohort was used for the derivation of the model, while it was tested exclusively on the second. Logistic regression modelling was then performed to develop a predictive model. The final model was used to predict the outcome of infants in the second cohort and infants divided into four risk quartiles. To give some indication of possible avoidable disease, the proportion of infants with HIE, potentially avoided by earlier delivery, was estimated by assuming that medicalized delivery by elective LSCS at 37 weeks would remove intrapartum risk of HIE for those infants undelivered at this point. RESULTS: In the final model seven covariates remained (parity, preeclampsia, polyhydramnios, prelabor rupture of membranes, gender, concerns over fetal growth and prematurity). When applied to the second cohort, a ROC curve for the prediction of developing HIE in the newborn period showed good evidence for association (AUC 0.68 (0.60 to 0.77)) and the risk score derived was strongly associated with the risk of HIE, resuscitation and stillbirth, and neonatal death (all p < 0.05). Elective delivery of high risk infants at 37 weeks gestation could prevent 14% of all HIE, with a NNT of 41. CONCLUSION: It is possible to combine routine antenatal findings to identify infants at higher risk of neonatal HIE, thereby recognizing those infants who may benefit most from delivery by elective caesarean section. This work suggests a clinical risk score permits antenatal identification of high-risk infants whose outcome may be amenable to changes in clinical practice to potentially reduce HIE rates, and its devastating consequences.
Rotation-supported Neutrino-driven Supernova Explosions in Three Dimensions and the Critical Luminosity Condition
Authors: Summa Alexander , Janka Hans-Thomas , Melson Tobias , Marek Andreas 
Published: January 2018

Abstract
We present the first self-consistent, 3D core-collapse supernova simulations performed with the Prometheus-Vertex code for a rotating progenitor star. Besides using the angular momentum of the 15 M
⊙ model as obtained in the stellar evolution calculation with an angular frequency of ∼10−3 rad s−1 (spin period of more than 6000 s) at the Si/Si–O interface, we also computed 2D and 3D cases with no rotation and with a ∼300 times shorter rotation period and different angular resolutions. In 2D, only the nonrotating and slowly rotating models explode, while rapid rotation prevents an explosion within 500 ms after bounce because of lower radiated neutrino luminosities and mean energies and thus reduced neutrino heating. In contrast, only the fast-rotating model develops an explosion in 3D when the Si/Si–O interface collapses through the shock. The explosion becomes possible by the support of a powerful standing accretion shock instability spiral mode, which compensates for the reduced neutrino heating and pushes strong shock expansion in the equatorial plane. Fast rotation in 3D leads to a “two-dimensionalization” of the turbulent energy spectrum (yielding roughly a −3 instead of a −5/3 power-law slope at intermediate wavelengths) with enhanced kinetic energy on the largest spatial scales. We also introduce a generalization of the “universal critical luminosity condition” of Summa et al. to account for the effects of rotation, and we demonstrate its viability for a set of more than 40 core-collapse simulations, including 9 and 20 M
⊙ progenitors, as well as black-hole-forming cases of 40 and 75 M
⊙ stars to be discussed in forthcoming papers.
Study of Outflows in Luminous Quasars at Redshift ∼0.4–0.8
Authors: Wang J. , Xu D. W. , Wei J. Y. 
Published: January 2018

Abstract
We perform a systematic study of outflow in the narrow-line region (NLR) of active galactic nuclei (AGNs) at z ∼ 0.4–0.8 based upon a large sample of ∼900 quasars at z ∼ 0.4–0.8. The sample is extracted from the Sloan Digital Sky Survey by mainly requiring that (1) the g-band magnitude is brighter than 19 mag and (2) the [O iii]λ5007 emission line has a signal-to-noise ratio larger than 30. Profiles of multiple emission lines are modeled by a sum of several Gaussian functions. The spectral analysis allows us to identify (1) a prevalence of both [O iii]λ5007 line blue asymmetry and bulk velocity blueshift of both [Ne iii]λ3869 and [Ne iii]λ3426 lines, when the [O ii]λ3727 line is used as a reference. The velocity offset of the [O iii]λ5007 line is, however, distributed around a value of zero, except for a few outliers. (2) Not only the significant [O iii]λ5007 line asymmetry, but also the large bulk velocity offsets of [Ne iii]λ3869 and [Ne v]λ3426 emission lines tend to occur in the objects with high L/L
Edd, which is considerably consistent with the conclusions based on local AGNs. With three M
BH estimation methods, the significance level of the trend is found to be better than 2.9σ, 3.2σ, and 1.8σ for [O iii], [Ne iii], and [Ne v], respectively. After excluding the role of radio jets, the revealed dependence of NLR gas outflow on L/L
Edd allows us to argue that the pressure caused by the wind/radiation launched/emitted from a central supermassive black hole is the most likely origin of the outflow in these distant quasars, which implies that the outflow in luminous AGNs up to z ∼ 1 have the same origin.
Observations of an Eruptive Solar Flare in the Extended EUV Solar Corona
Authors: Seaton Daniel B. , Darnel Jonathan M. 
Published: January 2018

Abstract
We present observations of a powerful solar eruption, accompanied by an X8.2 solar flare, from NOAA Active Region 12673 on 2017 September 10 by the Solar Ultraviolet Imager (SUVI) on the GOES-16 spacecraft. SUVI is noteworthy for its relatively large field of view, which allows it to image solar phenomena to heights approaching 2 solar radii. These observations include the detection of an apparent current sheet associated with magnetic reconnection in the wake of the eruption, and evidence of an extreme-ultraviolet wave at some of the largest heights ever reported. We discuss the acceleration of the nascent coronal mass ejection to approximately 2000 km s−1 at about 1.5 solar radii. We compare these observations with models of eruptions and eruption-related phenomena. We also describe the SUVI data and discuss how the scientific community can access SUVI observations of the event.
Profils et trajectoires des directeurs sûreté
Authors: Ocqueteau Frédéric 
Published: December 2017

L’actualité de ces derniers mois a révélé au grand public l’existence des directeurs de sûreté. Toutefois, la réalité de ce que recouvre leur fonction reste méconnue y compris pour certains observateurs avertis. Un mal sans doute réparé grâce au travail réalisé pour le CDSE par Frédéric Ocqueteau, chercheur au CNRS. Il nous présente ici les résultats exclusifs de son étude et nous plonge dans le monde discret de la sûreté d’entreprise pour identifier les profils, les compétences et les missions de ses acteurs. Tâche d’autant plus ardue en raison de la diversité de leurs profils et de l’absence de vision partagée de ce qu’est la « sécurité ». L’auteur voit d’ailleurs dans cette diversité un frein à la stabilisation de l’identité professionnelle des directeurs de sécurité-sûreté. Frédéric Ocqueteau rappelle que l’activité du directeur dépend de la structure, de la taille et du secteur d’activité de l’entreprise qu’il est chargé de protéger, mais également de son parcours individuel. Chaque directeur, selon son appartenance de corps et sa trajectoire personnelle, peut valoriser un savoir-faire spécifique et donc modeler la sûreté de l’entreprise pour laquelle il officie, selon qu’il vient d’une des trois filières identifiées : la filière privée ou voie interne, celle du ministère de l’Intérieur, et celle des militaires et des gendarmes. Conclusion de l’auteur : il semblerait qu’en dépit d’une apparente « civilianisation » du monde de la sécurité, l’expertise des anciens militaires et gendarmes continue d’être privilégiée par les entreprises.
Measurement of Health System Performance at District Level: A Study Protocol
Authors: Sharma Atul , Prinja Shankar , Aggarwal Arun Kumar 
Published: January 2018

Background Limited efforts have been observed in low and middle income countries to undertake health system performance assessment at district level. Absence of a comprehensive data collection tool and lack of a standardised single summary measure defining overall performance are some of the main problems. Present study has been undertaken to develop a summary composite health system performance index at district level. Methods A broad range of indicators covering all six domains as per building block framework were finalized by an expert panel. The domains were classified into twenty sub-domains, with 70 input and process indicators to measure performance. Seven sub-domains for assessing health system outputs and outcomes were identified, with a total of 28 indicators. Districts in Haryana state from north India were selected for the study. Primary and secondary data will be collected from 378 health facilities, district and state health directorate headquarters. Indicators will be normalized, aggregated to generate composite performance index at district level. Domain specific scores will present the quality of individual building block domains in the public health system. Robustness of the results will be checked using sensitivity analysis. Expected impact for public health The study presents a methodology for comprehensive assessment of all health system domains on basis of input, process, output and outcome indicators which has never been reported from India. Generation of this index will help identify policy and implementation areas of concern and point towards potential solutions. Results may also help understand relationships between individual building blocks and their sub-components.
¿Qué piensan los estudiantes universitarios frente a la formación investigativa??
Authors: Pinto Santos Alba Ruth , Cortés Peña Omar Fernando 
Published: January 2018

Este artículo de investigación presenta un análisis del aporte e impacto que tiene el proceso de formación sobre el desarrollo de competencias investigativas en estudiantes universitarios. Metodológicamente se asumió una investigación holística, operacionalizada a partir de un diseño mixto triangulado. La muestra se seleccionó aleatoriamente, contando con la participación de 104 estudiantes de últimos semestres de la Universidad de la Guajira. Las técnicas e instrumentos empleados fueron los foros de discusión y análisis de contenidos a nivel cualitativo, mientras que a nivel cuantitativo se aplicó una Escala de Actitudes frente a la Formación Investigativa, con un nivel de Confiabilidad <em>Alfa de Cronbach</em> de (<em>α</em>: ,849) e indicadores de consistencia interna (correlación ítem – escala) positivos y superiores a (<em>r</em>: ,30). El procesamiento estadístico de los datos se realizó en el programa SPSS versión 21. A partir de los resultados de orden cualitativo, se resalta que la existencia de contenidos curriculares en el campo de formación en investigación, no es garantía de desarrollo de competencias investigativas. En el orden cuantitativo, se destaca que el 90% de los estudiantes considera que el programa al que pertenece debe revaluar la forma como orienta la formación investigativa. La contrastación de los hallazgos permitió identificar la necesidad de generar espacios de reflexión para el desarrollo de estrategias de innovación educativa que permita enriquecer los modelos curriculares, así como la promoción de los escenarios extracurriculares para el desarrollo de las competencias investigativas.

Published: January 2018

<p>El trabajo visibiliza cómo es significada por el alumnado una experiencia de innovación docente en la universidad que despliega el proceso enseñanza-aprendizaje desde las ideas del construccionismo social (Gergen, 2015). Sus valoraciones fueron abordadas desde una perspectiva emic (San Martín, 2014), empleando el software de análisis cualitativo ATLAS.ti7. El alumnado (26) expresa que ha vivido una experiencia educativa inusual, siendo la flexibilidad la cualidad que reconocen como clave de la misma, en consonancia con propuestas pedagógicas comprometidas con la co-construcción del conocimiento. Los significados dados por el alumnado revalorizan la educación presencial, el aula es el lugar en el que se produce un aprendizaje inusual y un boom de ideas, subrayando su utilidad como espacio relacional que nutre la creatividad colaborativa. Emergen desafíos que invitan a la reflexión acerca de cómo seguir diseñando propuestas de innovación educativa en la universidad desde la generación relacional del conocimiento.</p>
¿Es interactiva la enseñanza en la Educación Superior? La perspectiva del alumnado
Authors: Álvarez Álvarez Carmen 
Published: January 2018

<p>La investigación ha puesto de manifiesto las ventajas que tiene la docencia basada en la interacción y el diálogo entre el alumnado y entre este y el profesorado en las aulas. Sin embargo, en España, la interacción como método de enseñanza-aprendizaje es aún empleada minoritariamente. En este artículo nos preguntamos por el estado de esta cuestión en el ámbito de la Educación Superior. Para dar respuesta a este interrogante se recoge una investigación exploratoria basada en la realización de cincuenta entrevistas en profundidad con estudiantes de todos los campos de conocimiento en dos universidades españolas. Los resultados muestran que los métodos didácticos de docencia universitaria habituales en la universidad española responden a un paradigma educativo de corte expositivo en el que los casos de enseñanza-aprendizaje por interacción constituyen episodios aislados. Asimismo, fuera del marco espacio-temporal de las aulas tampoco se producen numerosos encuentros interactivos para la enseñanza-aprendizaje entre el alumnado y entre el alumnado y el profesorado. Los resultados también muestran qué aspectos facilitan la interacción y qué aspectos la entorpecen. Es posible concluir la necesidad y urgencia de introducir prácticas de enseñanza-aprendizaje por interacción en la universidad española: el alumnado demanda un cambio metodológico y quienes han tenido algunas experiencias interactivas aseguran haberse implicado más en el estudio, haber profundizado más en el contenido, haber disfrutado con la materia y haber obtenido mejores resultados académicos. Las prácticas de enseñanza-aprendizaje por interacción son imprescindibles en la mejora de la calidad docente en el ámbito de la educación superior.</p>
Surgical Outcome of Thyroid Nodules with Atypia of Undetermined Significance and Follicular Lesion of Undetermined Significance in Fine Needle Aspiration Biopsy
Authors: Alqahtani Saad , Alsobhi Saif , Alsalloum Riyadh I , Najjar Saleh N , Al-Hindi Hindi N 
Published: January 2018

ABSTRACT
Aim
To correlate selected clinical and ultrasonographic (US) characteristics with the final histopathological diagnosis in patients with atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS), and whether this information can be used in planning the surgical approach.

Materials and methods
It is a retrospective study including the operated cases of AUS/FLUS from 2011 to 2014 treated at one center.

Results
This cohort included 87 women and 28 men. To test for independence between categorical variables, the chi-square test was used. There was no significant correlation between age or US variables and final pathological diagnosis. However, final diagnosis of malignancy was higher in men compared with women (64.3 and 41.4% respectively; p = 0.035). Furthermore, a significant association between the diagnosis of repeated fine needle aspiration biopsy (FNAB) and the final pathological diagnosis was noted (benign vs malignant, p = 0.005).

Conclusion
The FNAB has a significant role in the assessment of thyroid nodules. Our results showed no correlation between age, US variables, and the risk of malignancy. Male gender is associated with higher risk of malignancy.

Clinical significance
Determining the risk of malignancy and prediction of surgical outcome may help triaging cases for repeat FNA or proceeding to surgery.
