Relative age effects in American professional football
Authors: Heneghan Jack F. , Herron Michael C.
Published: June 2019

We test for the existence of relative age effects in professional American football. In a sample of 18,898 football players born on or after 1940, there is an excess of January and February births – consistent with a relative age effect associated with calendar year – as well as a slight increase in September births – consistent with the fact that some football players we analyze attended high school in states with fall school cutoff dates. We consider the possibility that relative age effects may affect skilled football positions more than positions relying heavily on player weight, and we find suggestive evidence of this. Lastly, and contrary to what has recently been shown in professional hockey, we find no evidence that misguided preferences for relatively older players lead to selection-based inefficiencies in football player drafting. Our results have implications for evaluating potential football players and speak broadly to the role of physiological factors beyond player control on athletic success.
Living a dog’s life: a putative gray wolf in a feral dog group
Authors: Popova Elitsa , Zlatanova Diana
Published: June 2019

The gray wolf and the domestic dog are closely related species that can interbreed and produce fertile offspring. In settings where unrestrained dogs are present in the wild, hybridization can happen naturally. However, the behavior of the resulting hybrids and their ecological impact is largely understudied. In September–November 2018, a putative gray wolf was repeatedly camera-trapped in a group of 10 presumably feral dogs in a remote mountainous area (the Osogovo Mountain) along the border between Bulgaria and North Macedonia. The most feasible explanation for this individual’s atypical behavior is that it is of hybrid origin (assumption based on phenotype). To the best of our knowledge, this is the first documented observation of such a kind. A discussion of its recruitment and position in the group is presented, setting the basis for further investigation of the complex interaction between wolves, dogs and hybrids in the wild.
Musical Activity of the Cantors of the Studnička Family from Suchomasty near Beroun
Authors: Michl Jakub
Published: June 2019

The music library of the Elizabethan Nuns in Prague contains a collection of music that was copied by cantors of the Studnička family from the village Suchomasty near Beroun. The first cantor in Suchomasty from 1769 was Josef Jan Jakoubek (1751–1810), the uncle of Jakub Jan Ryba, and after his departure for Mníšek pod Brdy in 1785, his successor was František Vincenc Studnička (1764–1826). František Ladislav Studnička (1797–1864) carried on the family tradition, followed by Otomar Studnička (1845 – after 1900), who later went to Prague and took the family music collection with him. He worked as a teacher at a public school in Libeň, then at the Saint Wenceslas Prison in Prague’s New Town. From 1884 he continued his work as a teacher at the prison in Pilsen-Bory. In 1889 he donated the family music collection to a convent of the Elizabethan Nuns. That material was integrated into the convent’s collection, and it was still being used in the twentieth century.

The multivalent effect of carbohydrates (glycoclusters) has been explored to study important biological targets and processes involving Trypanosoma cruzi (T. cruzi) infection. Likewise, CuAAC cycloaddition reactions (click chemistry) have been applied as useful strategy in the discovery of bioactive molecules. Hence, we describe the synthesis of 1,2,3-triazole-based tetravalent homoglycoclusters (1–3) and heteroglycoclusters (4 and 5) of d-galactopyranose (C-1 and C-6 positions) and sialic acid (C-2 position) to assess their potential to inhibit T. cruzi cell invasion and also its cell surface trans-sialidase (TcTS). The target compounds were synthesised in good yields (52–75 %) via click chemistry by coupling azidosugars galactopyranose and sialic acid with alkynylated pentaerythritol or tris(hydroxymethyl)-aminomethane (TRIS) scaffolds. T. cruzi cell invasion inhibition assays showed expressive low parasite infection index values (5.3–6.8) for most compounds. However, most glycoclusters proved to be weak TcTS inhibitors at 1 mM (<17 %), except the tetravalent sialic acid 3 (99 % at 1 mM, IC50 450 μM). Therefore, we assume that T. cruzi cell invasion blockage is not due to TcTS inhibition by itself, but rather by other mechanisms involved in this process. In addition, all glycoclusters were not cytotoxic and had significant trypanocidal activity upon parasite survival of amastigote forms.

Published: June 2019

This paper presents a comprehensive review of the remarkable achievements by Chinese scientists and engineers who have contributed to the multiscale process design, with emphasis on the transport mechanisms in stirred reactors, extractors, and rectification columns. After a brief review of the classical theory of transport phenomena, this paper summarizes the domestic developments regarding the relevant experiments and numerical techniques for the interphase mass transfer on the drop/bubble scale and the micromixing in the single-phase or multiphase stirred tanks in China. To improve the design and scale-up of liquid-liquid extraction columns, new measurement techniques with the combination of both particle image velocimetry and computational fluid dynamics have been developed and advanced modeling methods have been used to determine the axial mixing and mass transfer performance in extraction columns. Detailed investigations on the mass transfer process in distillation columns are also summarized. The numerical and experimental approaches modeling transport phenomena at the vicinity of the vapor-liquid interface, the point efficiency for trays/packings regarding the mixing behavior of fluids, and the computational mass transfer approach for the simulation of distillation columns are thoroughly analyzed. Recent industrial applications of mathematical models, numerical simulation, and experimental methods for the design and analysis of multiphase stirred reactors/crystallizers, extractors, and distillation columns are seen to garnish economic benefits. The current problems and future prospects are pinpointed at last.
Yeísmo in Majorcan Spanish: phonetic variation in a bilingual context
Authors: Rost Bagudanch Assumpció
Published: June 2019

This article addresses a particular characteristic of the variety of Spanish spoken in Majorca (Balearic Islands, Spain): the /ʎ/-/j/ merger (yeísmo). This island is home to a Catalan-Spanish bilingual community, meaning that Spanish speakers are in close contact with a system (Balearic Catalan) which is supposed to largely retain the /ʎ/-/j/ contrast. Given this context, our focus is to acoustically verify whether there is an interference from Balearic Catalan to Spanish in the sense of inhibiting yeísmo or, at least, favouring phonetic realisations other than those found in mainland Spanish. Our study concludes that a transfer in terms of allophonic variation does exist: in Majorcan Spanish lenited sounds ([i̯], [j]) are more common than in mainland Spanish.
Sull’origine della poesia romanza: ipotesi andalusa e mediolatina alla luce del rapporto fra rima e melodia
Authors: Di Santo Federico
Published: June 2019

Within the long-standing, and yet still lively debate over the origin of Romance poetry in general, and of regular rhyme in particular, one key element appears to have been often overlooked: music. Although it is very well known that Troubadour lyric poems were meant to be sung, their melodic form has so far indisputably been considered to be independent from the formal structure of the texts. However, a radical reconsideration of this common belief, based on a brand-new approach that takes orality into account, leads to the opposite conclusion that regular rhyme schemes, at their origins, were indeed closely related to the musical form of the songs. Linking rhymes to music may therefore represent a potentially decisive argument in the quest for the origin of Romance lyric poetry. For, even if rhymes and rhyme schemes may be found in many different and independent literary traditions, their structural relation to musical form is by far much rarer, hence offering a much more specific hint about the origin of Vernacular lyric forms, which are based on regular rhyme schemes. Tracing this metrical-musical technique back to its roots, may validate once and for all one of the two main theories competing around the origin of Vernacular lyric poetry, namely the Medieval Latin and the Andalusian Arabic theory.
The Role of Ferrotitanium as an Inoculant on the Microstructure and Mechanical Properties of Low-Alloy Steel
Authors: Mohammadaliha M. , Shahri F. , Boutorabi S. M.
Published: June 2019

In this work, the effects of ferrotitanium (0.5 wt.%) as an inoculant on the microstructure and mechanical properties of 0.24 % carbon-1 % chromium-1 % manganese-0.5 % silicon steel were studied. Optical microscopy and scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS) microanalysis were used for microstructural investigations. The phase structure of the ferrotitanium-added alloys was studied using X-ray diffraction (XRD). Microstructural observations show that a fine upper bainite lath is formed and allotriomorphic ferrite is eliminated by adding ferrotitanium to the main alloy. XRD revealed the presence of ferrite and austenite in the microstructure. Also, a decrease in dendrite arm spacing (DAS) was observed for 0.5 wt.% ferrotitanium-added alloy. Addition of 0.5 wt.% ferrotitanium caused the formation of titanium-molybdenum-carbon precipitates in austenite grain boundaries so that these particles acted as nucleon’s in austenite grain boundary and refined the microstructure. The yield strength, ultimate tensile strength, and percent elongation to fracture of the ferrotitanium-added samples are increased by 65, 68, and 57 %, respectively. Finally, the fracture surface of the alloys showed a cleavage fracture for the inoculated alloy.
Phenomenology and Space in Architecture
Authors: Saeid Soltani  , Nazan Kirci
Published: June 2019

Until recently, architecture has been mostly evaluated over its stylistic and visual characteristics. Whereas, the architectural space is primarily vital and therefore, it should not be evaluated independently of its environment and users. Pallasmaa emphasizes on the significance of experience and connection with the environment in architecture. Phenomenology, which aims to create sensory perception, is about creating an abstract experience beyond tangibility. Sensing beyond physical entities in spatial experience deepens meaning. Buildings and cities, essentially provide the necessary view to understand and confront the human existence. It is, therefore, important for architecture to be seen as the subject of phenomenology. This paper explores the relationship between phenomenology and architectural space through experience, sensation, and meaning. It argues that the relationship between human and built environment will be strengthened to the extent that the mentioned features could participate in the space.

Published: June 2019

Setaria equina (S. equina) is a filarial worm that exists in peritoneal cavity of equines. This study aimed to evaluate cytokine mediators tumour necrosis factor alpha (TNF-α), interleukin-4 (IL-4) and immunoglobulin G (IgG) responses in spontaneously S. equina infected and non-infected donkeys with emphasis on choosing the best antigen that could be used in diagnosis of such filarial infection. A total of 87 donkeys were examined. Two S. equina antigens: crude somatic S. equina antigen (CSS) and excretory secretory S. equina antigen (ESS) were prepared. They were evaluated in diagnosis of the infection using indirect ELISA and electrophoretically characterised through sodium dodecyl sulphate poly acrylamide gel electrophoresis (SDS-PAGE) and western blotting technique. The results indicated that both TNF-α and IL-4 in the serum of infected donkeys were significantly higher compared with the non-infected group at P<0.05 and P<0.01, respectively. However, the IL-4 level of infected donkeys was significantly higher than that of TNF-a (P<0.01). Apparent prevalence, specificity and positive predictive values (96.55%, 100%, and 100% each) of CSS showed higher diagnostic accuracy than that of ESS. In addition, electrophoretic protein profile and IgG reactivity of CSS antigen via western blot presented a prominent reactive protein band at 28 kDa. It was concluded that the CSS antigen was the best antigen that could be used in serodiagnosis of S. equina infection. The cytokine responses were explored in order to differentiate infected from non-infected donkeys.

Luminescence and energy-transfer mechanism of a praseodymium material
Authors: Liu Qian , Chen Wen-Tong , Luo Hui , Kuang Han-Mao
Published: June 2019

A praseodymium (Pr) material, [Pr(isonicotinic acid)2(H2O)4] n nNO3 (1), was synthesized through a solvothermal reaction and was characterized by single-crystal X-ray diffraction. It is characterized by a one-dimensional chain-like structure. The [Pr(isonicotinic acid)2(H2O)4] n n+ cationic chains and isolated nitrate (NO3 −) anions are interlinked by hydrogen (H)-bonding interactions, yielding a three-dimensional supramolecular network. Solid-state photoluminescence measurements revealed that it exhibits a yellow-light emission. The photoluminescence emission bands originate from the characteristic emission of the 4f electron intrashell transitions of 3 P 1 → 3 H 5 and 3 P 0 → 3 H 6 of the praseodymium ion (Pr3+). The energy-transfer mechanism is explained by the energy-level diagram of the praseodymium ion and the isonicotinic acid (C6H5NO2) ligand. The praseodymium material has remarkable Commission Internationale de l’Éclairage chromaticity coordinates of (0·4251, 0·4646). Therefore, it is a promising color converter for lighting and displays. It is found that isonicotinic acid is not an ideal ligand to excite Pr3+ ions, i.e. not a good “antenna”. The purity of the bulky sample was confirmed by PXRD. The FT-IR bands of the title complex were assigned. The title complex is thermally stable at about 90°C
Molecular dynamics simulations of single-walled carbon nanotubes and polymers
Authors: Zhang Danhui , Liu Zhongkui , Yang Houbo , Liu Anmin
Published: June 2019

In this study, molecular dynamics simulations were used to investigate the interfacial interactions between single-walled carbon (C) nanotubes (SWCNTs) and three different polymers – namely, polyacrylic acid, poly(methyl acrylate) and poly(methyl methacrylate). The results showed that the three different polymer chains could stabilize SWCNTs and then extend along the direction of SWCNTs. Among the three polymers, polyacrylic acid displayed the strongest interaction with SWCNTs, which was due to its having the highest interaction energy with SWCNTs. Furthermore, factors such as the initial angle between the three different polymer chains and nanotube axis and the length of the polymer were also investigated. The results displayed that the final structures and interaction energy were also different and the interaction energy increased with the increasing number of monomer. This research will be helpful in understanding the interfacial interactions between polymers and CNTs and will also lead to fabrication of high-performance polymer–CNT nanocomposites.
HOW AND WHEN IS SELF-EFFICACY RELATED TO ENTREPRENEURIAL INTENTIONS: EXPLORING THE ROLE OF ENTREPRENEURIAL OUTCOME EXPECTATIONS AND SUBJECTIVE NORMS
Authors: Santos Susana , Liguori Eric W.
Published: June 2019

This study investigates how and when general self-efficacy is related to entrepreneurial intentions. We propose that entrepreneurial outcome expectations function as a mediator in this relationship, while subjective norms act as a moderator. Using a sample of 1052 students from U.S. Public Universities, we tested a moderated mediation model. Results showed that general self-efficacy is positively related to entrepreneurial intentions through the mediating effect of entrepreneurial outcome expectations, and that this relationship is significantly positive for individuals with favourable subjective norms towards entrepreneurship, while significantly negative for individuals with less favourable subjective norms. These findings contribute to literatures on entrepreneurial intentions. Keywords: entrepreneurial intentions, self-efficacy, entrepreneurial outcome expectations, subjective norms

En los últimos años, el interés de las universidades y la administración pública por el fenómeno de creación de spin-off ha aumentado como una forma de transferir los resultados de la investigación al sector productivo.Esta creación de spin-off depende de varios factores, y uno de los más importantes es el género. De hecho, el Informe de la Comisión sobre la promoción de las mujeres innovadoras y el espíritu empresarial (2008) muestra que el espíritu empresarial femenino sigue siendo un desafío. En este campo, la literatura es aún escasa y nuestro estudio intenta contribuir a su aumento.Con este objetivo, llevamos a cabo un estudio cualitativo entre 42 académicos para identificar los factores determinantes del emprendimiento académico durante enero de 2017. Nuestros resultados identifican seis factores. Tras la identificación de estos elementos, se ha desarrollado un estudio cuantitativo entre 1,726 académicos (39% mujeres, 61% hombres), con el propósito de obtener la jerarquía de estos determinantes que llevan a los académicos a montar empresas spin-off.La técnica utilizada para el análisis ha sido el análisis conjunto, una técnica que, hasta donde nuestro conocimiento alcanza, no se ha utilizado para el estudio del emprendimiento académico.Nuestros resultados muestran diferencias de género en la jerarquía de los factores del emprendimiento académico, con implicaciones para la gestión de la transferencia de tecnología y para los responsables de las políticas universitarias.

Published: June 2019

Las concepciones y modelos dominantes de los procesos de decisión organizacional, de base determinista y reduccionista, han sido puestos en entredicho por las dinámicas propias de los contextos complejos que atraviesan las organizaciones. Tradicionalmente el baremo considerado para analizar dichas decisiones era el grado de racionalidad aplicado en el proceso, desplegándose así decisiones bajo racionalidad, racionalidad limitada o incertidumbre, de acuerdo a la posibilidad de contar con información plena, sesgada o escasa en el análisis y proceso decisorio específico. El objetivo de este trabajo es demarcar la necesidad de redefinir el modelo dominante enunciado, para avanzar hacia un modelado contextualizado por los despliegues estructurales y coyunturales que operan sobre el proceso decisorio, a partir de las tensiones producidas por los contextos complejos.La metodología utilizada se desarrolló bajo un enfoque cualitativo mediante entrevistas en profundidad con titulares, funcionarios, ejecutivos y gerentes de empresas de distintos sectores, áreas de desempeño, públicas o privadas, con o sin fin de lucro.Los resultados principales obtenidos apuntan al desarrollo de un proceso contingente decisional que incorpora las tramas culturales y vinculares de la organización en el proceso decisorio, de acuerdo a aspectos estructuras y coyunturales del proceso de gestión organizacional.Las implicaciones de este estudio tienden a colaborar con la dificultad que encuentran los futuros emprendedores y directivos de organizaciones en desarrollar procesos decisorios que se adecuen a las continuas demandas cambiantes del contexto sistémico de inserción de las organizaciones.

Published: June 2019

Aim. To study the impact of the aesthetic component of dental health on the quality of life of young patients.

Methods. 83 subjects with violation of the aesthetics of hard tissues of the anterior group of teeth were examined and treated. Assessment of stability of composite restorations with materials of Russian and foreign production was carried out according to Ryge criteria. A brief questionnaire (the world health organization quality of life WHOQOL-BREF) was used to assess the quality of life.

Results. With the material Filtek Z550 violation of surface preservation occurred in 6 (15.8%) out of 38 men and only 1 (2.2%) out of 45 women (p=0.026). With Estelux NK material the violation of the seal surface preservation occurred in 5 (13.2%) out of 38 men and 2 (4.4%) out of 45 women, the findings are not statistically significant (p=0.15). The total index of quality of life in men and women significantly improved 6 months after the restoration and amounted to 88.7±5.4 points (p=0.024) and 88.4±7.3 (p=0.034), respectively, compared to test results prior to treatment. Stability of the quality of the restoration according to Ryge criteria of both photocomposite materials (Estelux NK and Filtek Z550) had no significant differences, therefore, the domestic material Estelux NK, taking into account its financial availability, can be recommended for aesthetic dental rehabilitation of young patients.

Conclusion. Restoration of the aesthetic optimum of men and women of young age leads to a subjective improvement of psychological comfort and objective increase of self-perception indices.

Authors: Zagdyn Z M
Published: June 2019

Aim. To study the opinions of specialists in tuberculosis institutions on barriers and ways to improve the system fighting the spread of human immunodeficiency virus (HIV) and tuberculosis.

Methods. In the study questionnaires with open and closed questions were used among employees of tuberculosis facilities in four territories of the North-West Region of Russia (Saint-Petersburg, Leningrad, Arkhangelsk, and Kaliningrad oblasts) during six months in 2018. Total of 284 subjects were included. The questionnaire consisted of 19 structured questions. The respondents’ answers were compared interregionally and were analyzed integrally inside the blocks with the calculation of their ratios.

Results. According to the specialists’ opinion working in tuberculosis facilities, the main barriers to providing tuberculosis services for people living with HIV are low level of intersectoral interaction, migration, increase in the number of injecting drug users, lack of regional government support, inconsistency of regulation documents with the requirements of currant reality. As the main conditions for improvement of epidemic situation with association of HIV/tuberculosis, the respondents consider increasing administration of antiretroviral therapy to the patients with HIV, adequate treatment of tuberculosis in HIV-infection and raising awareness of HIV-infection and tuberculosis by the population.

Conclusion. To improve the existing system of fighting HIV/tuberculosis, strengthening the connection among the stakeholders may be possible, especially between tuberculosis facilities and detention centers giving the valuable access to antiretroviral therapy, chemoprophylaxis and tuberculosis treatment, including establishment of low-threshold centers, improved population awareness of tuberculosis and HIV-infection.

Aim. To evaluate the results of surgical treatment of post-infarction left ventricular aneurysms with on-pump beating heart technique.

Methods. In our center from April, 2009 to January, 2014 169 patients had reconstruction of the left ventricle with on-pump beating heart technique. Among the patients 159 were males (94.1%) and 10 of them were females (5.9%), average age 53.8±8.9 years (39 to 72 years). Angina pectoris class I (according to the classification of Canadian Heart Association) was established in 7 (4.1%) patients, class II - in 49 (29.0%), class III - in 107 (63.3%), class IV - in 4 (2.4%), unstable angina in 2 (1.2%) patients. Chronic heart failure class I (according to New York Heart association functional classification) was diagnosed in 5 (3.0%) patients, class II in 37 (21.9%), class III in 124 (73.4%), class IV in 3 (1.8%) patients. Average ejection fraction of the left ventricle was 38.6±7.9% (25 to 67%). Mitral valve insufficiency stage 2-3 was revealed in 23 (13.6%) patients.

Results. Endoventriculoplasty of the left ventricle by Dor's technique was performed in 49 (29.0%) patients, auto-septoplasty of the left ventricle - 59 (34.9%) patients, linear repair in 40 (23.7%) patients. Combined surgical interventions were performed in 21 (12.4%) patients. In-hospital lethality was 2.4% (n=4).

Conclusion. Left ventricular reconstruction with on-pump beating heart technique without cardioplegic arest is effective and safe; the method allows performing remodelling of the left ventricle and reaching the target volume parameters.
For the 30th anniversary of laparoscopic cholecystectomy: problems remain

Published: June 2019

The review describes perioperative complications of laparoscopic cholecystectomy. Over the past 30 years, laparoscopy has become the «gold standard» for cholecystectomy and one of the most frequently performed procedures in abdominal surgery. Nevertheless, despite the advantages of the method, it has an «Achilles heel» - the frequency of iatrogenic damage to the extrahepatic bile ducts is 3-5 times higher than with an open cholecystectomy. This complication has a negative effect on the survival of patients after surgery, leads to deterioration in the quality of life and is a major source of legal costs in many countries. In general, the total range for any damage to the biliary tract during laparoscopic cholecystectomy is 0.32-0.52%, while the complication rate and mortality rate are 1.6-5.3% and 0.08-0.14%, respectively. Patients who have undergone a complete intersection of the hepaticoholedochus, become «bile cripples» for life. Recurrent cholangitis, strictures of anastomoses with a possible outcome in liver cirrhosis are quite likely in later periods after damage to the intrahepatic bile ducts. Technological efforts to improve the results of laparoscopic cholecystectomy reside. These include the routine use of intraoperative cholangiography, infrared fluorescent cholangiography, etc. Nevertheless, despite the growing number of methods designed to reduce these complications, evidence of their effectiveness remains limited. The most important factors ensuring the safety of laparoscopic cholecystectomy are recognized: understanding of anatomy, adequate exposure when using electrosurgery, psychological readiness to invite a senior colleague in time for help, the ability to recognize a situation that requires conversion and rejection of laparoscopy.

W niniejszym tekście proponuję poszerzenie perspektywy filozofii międzykulturowej o ujęcie enaktywistyczne. Zakładam, że enaktywizm daje nowe możliwości ufundowania zasady solidarności. Koncentruję się na zaletach postrzegania człowieka jako żywego systemu autopoietycznego: życiu w i poprzez interakcje, byciu tym samym i innym zarazem, przekraczaniu granic między istotami żywymi ludzkimi i nieludzkimi. Rozważam również zagadnienie możliwości przekroczenia błędu naturalistycznego.
„Niezdeterminowanie” granic poznania w znaturalizowanym relatywizmie pojęciowym W.V.O. Quine’a
Authors: Kubić Andrzej
Published: June 2019

W artykule opisano znaturalizowany relatywizm pojęciowy W.V.O. Quine’a w perspektywie problematyki granic wiedzy. Quine był jednocześnie relatywistą pojęciowym (mamy do wyboru wiele równoważnych pod względem epistemologicznym systemów pojęciowych) i empirycznym naturalistą (przyjmował naturalistyczną koncepcję treści empirycznej zredukowanej do pobudzeń odbieranych przez nasze powierzchnie sensoryczne w ramach behawioryzmu lingwistycznego). Ponadto bezpośrednio podejmował zagadnienie granic wiedzy, jednak jego główną intencją – jak sam zaznaczył – była przede wszystkim analiza i modyfikacja tytułowego problemu, a nie próba udzielenia na niego odpowiedzi. Krótko mówiąc, zdaniem Quine’a zagadnienie to można zredukować do kontekstu językowego.

Le Semestre. Une lecture psychanalysante
Authors: Hayward Annette
Published: June 2019

Cette lecture psychanalysante du Semestre, survenue un peu malgré moi parce que le défi du labyrinthe que constitue ce roman y entraînait, aboutit à la conclusion — à la suite d’une étude approfondie qui identifie les principaux pôles d’attraction ou d’obsession du récit — que la métaphore obsédante la plus importante du texte est celle du fœtus-tétard. L’étude souligne aussi comment cette œuvre génériquement insolite remet en question, au moyen de ses multiples mises en abyme, plusieurs concepts clefs de la critique littéraire contemporaine dont la distinction entre auteur et narrateur et celle entre le critique et l’œuvre analysée.AbstractThis psychoanalytical reading of Le Semestre, into which I was drawn despite myself by the challenge represented by this labyrinthine novel, comes to the conclusion – after a close study of the text that identifies the main poles of attraction or obsession of the narration – that the most important métaphore obsédante (the recurring metaphor) is that of the tadpole/foetus. This article also studies the way in which this generically experimental work questions several of the key concepts of contemporary literary criticism such as the distinction between author and narrator or between the critic and the object of literary criticism.
Gérard Bessette, Homo Ontarionensis ?
Authors: Robidoux Réjean
Published: June 2019

En s’attardant à la biographie de l’auteur ainsi que sur ses deux romans les plus autobiographiques, L’Incubation et Le Semestre, cet article souligne l’importance de la question identitaire dans l’œuvre, ainsi que la complexité d’être Canadien français/Québécois alors qu’on vit depuis longtemps en dehors du Québec. Il montre également les raisons pour lesquelles il serait possible de considérer Gérard Bessette auteur comme homo ontarionensis.AbstractPassing in review details from the author’s biography as well as passages from his two most autobiographical novels, L’Incubation and Le Semestre, this article illustrates the importance of the theme of identity in his works, as well as the complexity of being French-Canadian then Québécois while living outside of Québec for such a long period of time. It also underscores the reasons why it is possible to consider Gérard Bessette as a homo ontarionensis.
Henri Michaux lecteur de Maurice Barrès
Authors: Vrydaghs David
Published: June 2019

Paradoxal à première vue, le rapprochement entre le poète Henri Michaux et le romancier nationaliste Maurice Barrès s’impose historiquement, tant Barrès fut un auteur incontournable pour la génération de Michaux. Analysant les textes de Michaux dans lesquels la référence à Barrès est manifeste, cet article se propose d’interroger la dette du poète à l’égard du romancier.AbstractPutting together the lyric poet Henri Michaux and the nationalist novelist Maurice Barrès can seem paradoxical but it is obvious from an historical point of view Barrès is a key figure for Michaux’s generation. This article questions the Barrès influence in the first works of the Belgian poet.
Braconnages identitaires sur la côte du Pacifique
Authors: Poirier Guy
Published: June 2019

Cet article étudie sept recueils de nouvelles écrits par des auteurs francophones de la Colombie-Britannique entre 1988 et 2007. Grâce à la théorie du braconnage identitaire développée par Simon Harel, il permet de mieux saisir les caractéristiques de ces recueils où sont regroupées des nouvelles reflétant le monde du soi des auteurs (leur passé, leurs lieux d’origine) et les nouvelles établissant un dialogue avec l’autre, c’est-à-dire avec le territoire de la Colombie-Britannique. Abstract This paper analyzes seven collections of short stories written by British Columbian Francophone authors from 1988 to 2007. Taking its cue from Simon Harel’s notion of “poaching” as applied to identity constructions, it provides a deeper understanding of the characteristics of these collections which bring together stories that explore the authors’ world of the self (their past, their origins) and stories that engage a dialogue with the other, that is, with the territory of British Columbia.

Published: June 2019

Carcinoma occurring the setting of chronic calcific pancreatitis (CCP) are usually multifocal, poorly differentiated, advanced on presentation and associated with poor overall survival. Hence it is imperative that these patients should be identified in the early stages of malignant progression where by curative resection can then be employed. If not, only palliative approaches are feasible in advanced stages. We wish to present our experience of pancreatic carcinoma in the setting of CCP along with a review of literature.

Authors: Murugesan Angatha Kumar , Govindasamy Rajesh , Ismail Patel Yahya
Published: June 2019

Background: Intertrochanteric fractures are disabling injuries in elderly population and they are the most frequently operated fracture type which has the highest postoperative fatality rate of all surgically treated fractures. The objective of the study was to evaluate the functional outcomes of intertrochanteric fractures treated with proximal femoral nail (PFN) in elderly patients.

Methods: A retrospective study of 24 patients, all above 60 years treated with PFN between March 2016 to April 2018. Data collected include age, sex, mechanism of injury, type of fracture pattern according to Boyd and Griffin’s classification. Patients were followed up at intervals of 6, 12, 18 and 24 weeks and final results were evaluated using Kyle’s criteria at the end of 24th week. All patients had a minimum follow up of one year.

Results: The study included 24 patients, 10 males, 14 females with mean age of 75.77 years (range: 60-82 years). The fracture union rate was 96% and average union time was 14.2 weeks. Our results were excellent (80%), good (8%), fair (8%) and poor (4%). Our complications include thigh pain (20%) shortening (20%), varus displacement (8%), knee and hip stiffness (8%), z effect (4%) and non-union (4%).

Conclusions: PFN is a reliable fixation in intertrochanteric fractures only after good intraoperative reduction leading to high rate of bone union and with reduced rate of implant failure or complications.

Authors: Abdullah Alharbi Awatif , Yang Cuihong
Published: June 2019

The research focuses on scientific instructional approaches which take into consideration the impact of such factors as influence and motivation and thus can help provide guidance on practical classroom techniques that can help in fortifying the students’ success in mathematics. The paper investigates ways to achieve better math results among students by stimulating their motivation using active learning paradigm. The study aims to explore the methods of active learning applied in primary school math classes. Our results appear to add to the literature supporting the supposition that active learning has a direct effect on the students’ success and consequently, their achievement. We provide empirical evidence for factors predicting higher math learning achievement, and accordingly, propose an improved student-centered active learning teaching method to help students develop higher-order problem-solving skills, comprising of a combination of previously verified strategies which help to foster a positive attitude towards mathematics.

Authors: Ochoa-Martínez Daniel Leobardo , Pérez-García Eduardo Alberto , Carrillo-Benítez María Guadalupe , Zamora-Macorra Erika Janet , Orozco-Cirilo Darío
Published: June 2019

En el Orquideario de Miguel Ángel Soto Arenas, de la Facultad de Ciencias UNAM, se han detectado plantas con síntomas consistentes en clorosis, variegado, necrosis y mosaico. Varias de estas plantas son especies endémicas de México y a la fecha no existe información sobre su manejo fitosanitario. Por lo tanto, el objetivo del presente estudio fue conocer a los virus asociados a estos síntomas mediante pruebas de ELISA, RT-PCR, plantas diferenciales y análisis filogenéticos. Se detectó al Odontoglossum ringspot virus (ORSV) y al Cymbidium mosaic virus (CymMV) en el 89% de las plantas con síntomas muestreadas. Las plantas diferenciales Nicotiana tabacum var. xhanti N. glutinosa, Chenopodium quinoa, C. amaranthicolor y Datura stramonium inoculadas mecánicamente con tejido foliar positivo a ambos virus mostraron lesiones locales seis días después de la inoculación y sólo CymMV infectó sistémicamente a N. benthamiana. El análisis filogenético mostró que estos virus se agruparon con aislamientos de países asiáticos lo que sugiere que la infección se originó probablemente por el intercambio de material vegetal entre productores. Este es el primer reporte del CymMV y ORSV infectando a Barkeria, Lycaste, Rossioglossum, Masdevallia, Leochilus, Stanhopea, Maxillaria, Epidendrum sec. Oerstedella, Dendrobium, Sobralia y Cuitlauzina en México.

Este estudo objetivou analisar perfil e fatores associados aos óbitos por tuberculose em um município no sul de Mato Grosso, entre 2008 a 2017. Estudo ecológico e descritivo com dados secundários. As análises estatísticas descritiva e comparativa incluíram teste qui-quadrado de Pearson e exato de Fisher, para variáveis categóricas, e teste Kruskal-Wallis, para variáveis contínuas. Considerado intervalo de confiança de 95% e aplicada razão de chances. Foi utilizado software estatístico R. Foram 774 notificações por tuberculose, sendo 32 óbitos (4,13% do total dos casos). O perfil dos óbitos seguiu o padrão sexo masculino, faixa etária adulta, raça parda, com ensino fundamental e residentes da zona urbana; predomínio da forma clínica pulmonar, exame para HIV negativo e não alcoolistas. A razão de chances significativa foi para faixa etária em relação aos óbitos. Concluído, este estudo mostrou que o perfil dos óbitos é, em sua maioria, indivíduos em situação de vulnerabilidade; portanto poderá contribuir para que a gestão municipal realize um planejamento estratégico das ações de prevenção, diagnóstico precoce e controle dos casos de tuberculose, evitando, assim, possíveis casos de óbitos.
