Published: July 2017

Abstract. The response of surface ozone (O3) concentrations to basin-scale warming and cooling of Northern Hemisphere oceans is investigated using the Community Earth System Model (CESM). Idealized, spatially uniform sea surface temperature (SST) anomalies of ±1 °C are individually superimposed onto the North Pacific, North Atlantic, and North Indian oceans. Our simulations suggest large seasonal and regional variability in surface O3 in response to SST anomalies, especially in the boreal summer. The responses of surface O3 associated with basin-scale SST warming and cooling have similar magnitude but are opposite in sign. Increasing the SST by 1 °C in one of the oceans generally decreases the surface O3 concentrations from 1 to 5 ppbv. With fixed emissions, SST increases in a specific ocean basin in the Northern Hemisphere tend to increase the summertime surface O3 concentrations over upwind regions, accompanied by a widespread reduction over downwind continents. We implement the integrated process rate (IPR) analysis in CESM and find that meteorological O3 transport in response to SST changes is the key process causing surface O3 perturbations in most cases. During the boreal summer, basin-scale SST warming facilitates the vertical transport of O3 to the surface over upwind regions while significantly reducing the vertical transport over downwind continents. This process, as confirmed by tagged CO-like tracers, indicates a considerable suppression of intercontinental O3 transport due to increased tropospheric stability at lower midlatitudes induced by SST changes. Conversely, the responses of chemical O3 production to regional SST warming can exert positive effects on surface O3 levels over highly polluted continents, except South Asia, where intensified cloud loading in response to North Indian SST warming depresses both the surface air temperature and solar radiation, and thus photochemical O3 production. Our findings indicate a robust linkage between basin-scale SST variability and continental surface O3 pollution, which should be considered in regional air quality management.
Regional and global climate for the mid-Pliocene using the University of Toronto version of CCSM4 and PlioMIP2 boundary conditions
Authors: Chandan Deepak , Peltier W. Richard
Published: July 2017

Abstract. The Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) is an international collaboration to simulate the climate of the mid-Pliocene interglacial, corresponding to marine isotope stage KM5c (3.205 Mya), using a wide selection of climate models with the objective of understanding the nature of the warming that is known to have occurred during the broader mid-Pliocene warm period. PlioMIP2 builds on the successes of PlioMIP by shifting the focus to a specific interglacial and using a revised set of geographic and orbital boundary conditions. In this paper, we present the details of the mid-Pliocene simulations that we have performed with a slightly modified version of the Community Climate System Model version 4 (CCSM4) and the enhanced variant of the PlioMIP2 boundary conditions. We discuss the simulated climatology through comparisons to our control simulations and to proxy reconstructions of the mid-Pliocene climate. With the new boundary conditions, the University of Toronto version of the CCSM4 model simulates a mid-Pliocene that is more than twice as warm as that with the boundary conditions used for PlioMIP Phase 1. The warming is more enhanced near the high latitudes, which is where most of the changes to the PlioMIP2 boundary conditions have been made. The elevated warming in the high latitudes leads to a better match between the simulated climatology and proxy-based reconstructions than possible with the previous version of the boundary conditions.

Abstract. The CHASE-PL (Climate change impact assessment for selected sectors in Poland) Climate Projections – Bias Corrected Daily Precipitation and Temperature dataset 5 km (CPLCP-GDPT5) consists of projected daily minimum and maximum air temperatures and precipitation totals of nine EURO-CORDEX regional climate model outputs bias corrected and downscaled to 5 × 5 km grid. Simulations of one historical period (1971–2000) and two future horizons (2021–2050 and 2071–2100) assuming two Representative Concentration Pathways (RCP4.5 and RCP8.5) were produced. We used the quantile mapping method and corrected any systematic bias in these simulations before assessing the changes in annual and seasonal means of precipitation and temperature over Poland. Projected changes estimated from the multi-model ensemble mean showed that annual means of temperature are expected to increase constantly by 1 °C until 2021–2050 and by 2 °C until 2071–2100 assuming the RCP4.5, which is accelerating assuming the RCP8.5 scenario and can reach up to almost 4 °C by 2071–2100. Similarly to temperature, projected changes in regional annual means of precipitation are expected to increase by 6 % to 10 % and by 8 % to 16 % for the two future horizons and RCPs, respectively. Similarly, individual model simulations also exhibited warmer and wetter conditions on an annual scale, showing an intensification of the magnitude of the change at the end of the 21st century. The same applied for projected changes in seasonal means of temperature showing a higher winter warming rate by up to 0.5 °C compared to the other seasons. However, projected changes in seasonal means of precipitation by the individual models largely differ and are sometimes inconsistent exhibiting spatial variations which depends on the selected season, location, future horizon and RCP. The overall range of the 90 % confidence interval predicted by the ensemble of multi-model simulations was found to likely vary between −7 % and +40 %, expected to occur in summer assuming the RCP4.5 scenarios and in winter assuming the RCP8.5 scenario, respectively, at the end of the 21st century. Finally, this high-resolution bias-corrected product can serve as a basis for climate change impact and adaptation studies for many sectors over Poland.

Evaporation suppression and energy balance of water reservoirs covered with
self-assembling floating elements
Authors: Aminzadeh Milad , Lehmann Peter , Or Dani
Published: July 2017

Abstract. The growing pressure on natural fresh water resources and projected climate variability would expand the need for water storage during rainy periods. Evaporative losses present a challenge to efficient water storage reservoirs, especially in arid regions with chronic water shortages. Among the various methods for suppressing evaporative losses, the use of self-assembling floating elements offers a simple and scalable solution especially for small reservoirs. The use of floating elements is not new, yet the science behind the design and the resulting performance including other effects on the water body remain empirical. We propose a systematic approach for modeling the energy balance and fluxes from covered water surfaces considering element geometry, radiative properties and local conditions. The water energy balance equation was linked to the energy balance of floating discs on the surface of reservoir to consider the effect of surface coverage and cover properties on radiative energy storage within the water body and surface heat fluxes. The modeling results demonstrated significant drop in evaporative losses from covered reservoirs where incoming radiative flux is primarily intercepted by the cover surface and released into the atmosphere in form of long wave radiation and sensible heat fluxes yielding much higher Bowen ratio over covered relative to uncovered water reservoirs. The theoretical approach provides a scientific basis for an important water resource protection strategy and a predictive framework for design purposes.
Satellite drag effects due to uplifted oxygen neutrals during super magnetic storms
Authors: Lakhina Gurbax S. , Tsurutani Bruce T.
Published: July 2017

Abstract. During intense magnetic storms, prompt penetration electric fields (PPEFs) through E×B forces near the magnetic equator uplift the dayside ionosphere. This effect has been called the “dayside superfountain effect”. Ion-neutral drag forces between the upward moving O+(oxygen ions) and oxygen neutrals will elevate the oxygen atoms to higher altitudes. This paper gives a linear calculation indicating how serious the effect may be during an 1859-type (Carrington) superstorm. It is concluded that the oxygen neutral densities produced at low-Earth-orbiting (LEO) satellite altitudes may be sufficiently high to present severe satellite drag. It is estimated that with a prompt penetrating electric field of ~ 20 mV/m turned on for 20 min, the O atoms and O+ ions are uplifted to 850 km where they produce about 40 times more satellite drag per unit mass than normal. Stronger electric fields will presumably lead to greater uplifted mass.
A continuum model for meltwater flow through compacting snow
Authors: Meyer Colin R. , Hewitt Ian J.
Published: July 2017

Abstract. Meltwater is produced on the surface of glaciers and ice sheets when the seasonal surface energy forcing warms the snow to its melting temperature. This meltwater can run off the surface in streams or percolate through the porous snow and refreeze, which warms the subsurface through the release of latent heat. We model the percolation process from first principles using a continuum model that includes heat conduction, meltwater percolation and refreezing, as well as mechanical compaction. The model is forced by surface mass and energy balances. When the surface temperature reaches the melting point, we compute the amount of meltwater produced and allow it to percolate through the snow according to Darcy's law, or to run off the surface if the snow is already saturated. The model outputs the temperature, density, and water content profiles as well as the surface runoff and water storage. We compare the propagation of freezing fronts that occur in the model to observations from the Greenland ice sheet. The model applies to both accumulation and ablation areas and allows for a transition between the two as the surface energy forcing varies. The largest firn temperatures occur at intermediate values of the surface forcing when perennial water storage is predicted.

This article deals with the ‘glass ceiling’ phenomenon based on the fact that a disproportionately low number of women access managerial positions by analyzing gender differences in the ‘educational profile’ and ‘professional profile perceived’. The sample is conducted among 165 undergraduate economics students (54 males and 111 females) in the final year of college in Spain at the time they were planning their future professional career. The methodology used is based on two approaches. First, an analytic model using Structural Equations Model (SEM) that leads us to explore perceptual differences in favorite subjects, professional ambitions, values associated to the workplace and mobility. Second, a causal analysis following the System Dynamics methodology to describe the women’s behavior in explaining their self-exclusion from managerial positions. Findings confirm the existence of an educational system biased by gender and reveals that while men are more ambitious professionally and show greater capacity to geographical mobility, women require greater motivation at work. Moreover, we find that the factors explaining why women are still far from reaching senior management positions are both external (gender stereotypes or organizational policies) and internal ones (self-confidence, self-esteem). Finally, we propose a set of education measures as a starting point to implement public policies which could reduce women´s barriers to break their glass ceiling.

Published: July 2017

A suitable plant regeneration system has been established using 3-4 weeks old calli derived from immature and mature seeds of four wheat varieties viz. Pavon 76, Akbar, Barkat, and Kanchan. As plant growth regulators, various auxins (2,4-D, BAP and IAA) either single or in combination were used in MS medium. The variety Pavon 76 showed maximum (72.25%) callus induction and Akbar exhibited the lowest (37.78%) from calli derived from immature seeds. Hormonal effects on callus induction were evaluated and significant results were found in case of genotypes at P <0.01. Out of four genotypes, the highest frequency of plant regeneration was recorded in Pavon 76 (67.00%) and lowest in Kanchan (43.10%) when 1.5 mg/l BAP and 0.5 mg/l IAA was added in the medium. It was observed that Pavon 76 produced highest number of green plants than others. For mature seeds all of the mentioned genotypes showed significant difference with maximum frequency of callusing in Pavon 76 (69.57%) in MS + 2.5 mg/l 2,4-D followed by Kanchan (60.84%), Barkat (52.73%), and Akbar (47.19%). For plant regeneration, Pavon 76 also showed best performance (64.36%) in MS + 2.0 BAP + 1.0 mg/l IAA, using calli derived from mature seeds. The other genotypes Barkat, Kanchan and Akbar exhibited 59.44, 52.71 and 52.32% regeneration in the same medium respectively. Here, the lowest regeneration (40.63%) was found in Akbar. In this case, it was aimed to establish a suitable protocol for in vitro callus induction and regeneration for advance biotechnological research on wheat in Bangladesh.

Steve Biko and the Liberatory Potential of Non-Racialism and Post-Racialism
Authors: Harris Kimberly Ann
Published: July 2017

Discussions of non-racialism in South Africa and discussions of post-racialism in the United States are sufficiently similar to invite the question as to whether South African thinkers could help to develop new ways of thinking about post-racialism and its potential in the United States. Biko's ideas are rarely taken up in the United States, yet they are relevant to contemporary discussions in critical philosophy of race. This article begins with an evaluation of the typology of non-racialism provided by Rupert Taylor and the historical study of non-racialism provided by Julie Frederikse, distinguishing different understandings of non-racialism. The second section presents Biko's understanding of non-racialism, arguing that Biko's understanding of which is embedded in his account of Black Consciousness, and not a variant of racial eliminativism. The final section focuses on the striking similarities between understandings of non-racialism and post-racialism using a distinction it introduces between principled and progressive forms of both these terms. Ultimately, this article makes the case for a progressive understanding of post-racialism, which has yet to be articulated and is too easily dismissed in the United States.

Published: July 2017

En el siglo XX, Arquitectura Moderna experimentó cambios y transformaciones consecuencia de las múltiples crisis naturales, económicas, políticas, bélicas y sociales. Cada escenario de conflicto, se convertía en un punto de inflexión y en un nicho de oportunidades a explorar por la arquitectura, que se gestaba entre la invención y la reproducción. Mediante la complejidad de los sistemas y la aparición de nuevos mecanismos de transmisión y materialización de las ideas, surge la herramienta del juego, para facilitar ejercicios de improvisación, variación, repetición y azar. La capacidad productiva del juego, durante el proceso de un proyecto, está determinada por su contexto y sus reglas. Utilizando la crisis como tablero de juego, se proponen 3 herramientas productivas: juegos de azar, juegos de construcción y juegos de reglas, que puedan dar respuesta a 3 situaciones cíclicas de necesidad con reglas de juego distintas: emergencia, informalidad y provocación.

Authors: Moraes Caroline , Michaelidou Nina , Canning Louise
Published: July 2017

This paper addresses a knowledge gap by presenting an empirical investigation of a group coursework protocol and peer assessment system (GCP&PAS) used in a UK university to support postgraduate marketing students in their assessed group activities. The aim of the research was to examine students' understanding of the GCP&PAS and their attitudes towards assessed group coursework and peer assessments generally. The study also sought to identify any differences in such attitudes as a result of group conflict. It was found that students are supportive of the principles of assessed group work and peer evaluation, but that there are differences in attitudes towards the GCP&PAS between those who experience group conflict and those who do not. The paper contributes to the literature in that it highlights the meaning of the research findings with regard to students' preparedness for work. It also recommends further examination of conflict and other factors such as culture and gender in the investigation of alternative peer evaluation systems.
Universities and Innovation in a Factor-Driven Economy
Authors: Hadidi Hala El , Kirby David A.
Published: July 2017

In the contemporary knowledge-based global economy, universities are required to operate more entrepreneurially, commercializing the results of their research and spinning out new knowledge-based enterprises. In this article, the third in a series by the authors, case studies are presented of activities in three Egyptian universities to demonstrate what is being done in Egypt and the challenges Egyptian universities face when they attempt to collaborate with industry and contribute to the innovation process. The results reveal that such initiatives are often the result of external influences and are not embedded in the core strategic planning activity of the institutions in which they are located. Accordingly, they often have difficulty surviving after the initial project funding is ended, not least because the important partnership links with industry remain largely underdeveloped. The authors consider the implications of the findings for policy formulation and argue for a coherent strategy that embeds the ‘Third Mission’ in the core activities of each institution and facilitates university–industry collaboration.

Economic development occupies a significant status is Islam, as Muslims are commanded to settle and advance the earth. Since anything required to perform a duty is a duty itself, settling the earth can be achieved only by development, which can be achieved by production. The latter builds the earth and assists man in worshipping God.The present paper concentrates on the role of macroeconomics in accomplishing economic development from an Islamic perspective. The Noble Qur’an verses and Hadith traditions are reported from specialists in a bid to provide the sought complete picture.Section One investigates the capitalistic view to solve economic crises, which represent the major obstacle to any stage of development. Section Two defines economic development from an Islamic perspective, as well as the criteria set to solve relevant problems. Section Three explores the obstacles to sustainable development in the Islamic World and proposes solutions to alleviate them.This brief study sheds light on the Islamic approach to (sustainable) development, showing the resulting public economic welfare, which would be definitely reflected on individual well-being.The major conclusion that sustainable development is a comprehensive concept associated with the continuity of economic, Poverty and unemployment are the most crucial obstacles that hinder sustainable development.

Authors: Sargin Nurten
Published: July 2017

The amount of bullying escalating in schools in recent years has been approached as an issue that needs to be investigated, whose causes need to be searched and for which preventive efforts should be made. This study is aimed at examining the bullying tendencies among preadolescents. The study was carried out with middle school preadolescents in Konya between the years 2016 and 2017. The voluntary participants were 122 female and 78 male students with an age range of 13 to 14 years. The participants were administered the Bullying Tendency Scale, which was developed and whose validity and reliability was established by Dölek (2002), and the demographic information about the students were collected using a Personal Information Form developed by the researcher. Analysis of the data obtained in the study revealed significant results in favour of male students in negative reflection, lack of emotional sharing, causing distress, use of force and bullying tendency according to the gender of participants. In terms of age factor, significant results were obtained in favour of 14 year-olds in causing distress, use of force and bullying tendency. For negative reflection, no significant difference was found in justification and lack of emotional sharing according to the age of preadolescents. Similarly, no significant difference was found in relation to the socio-economic status of the participants. Recommendations were offered based on the results of the study.

Restorative justice and schools. An opportunity for socially vulnerable youngsters?

Restorative justice has evolved from an unknown concept towards a model that is considered world-wide when it comes to changes in the penal and youth justice sector. The restorative model expands towards handling conflicts in other areas, such as neighbourhoods, business, welfare issues, family matters and behavioural problems in schools. This article deals with the latter. Restorative practices are based upon an open and respectful dialogue, which presupposes certain attitudes and capacities. The article looks into possible risks, but especially the chances restorative practices in schools can offer for socially vulnerable youth.

Published: July 2017

Authenticity is crucial to the seafood industry, as substitution and mislabeling have important economic, environmental, and food safety consequences. Toaddress this problem, protein profiling and softwarealgorithm techniques were developed to classify fishmuscle samples by species. The method uses water-based protein extraction, chip-based microfluidic electrophoresis (Agilent 2100 Bioanalyzer) for the analysis of high abundance fish muscle proteins, and a novel data analysis method for species-specific proteinpattern recognition. The method's performance in distinguishing commercially important fish from commonly reported substitutions was evaluated using sensitivity, specificity, and accuracy determinations with all three performance measures at >98% for commonsubstitutions. This study demonstrates that uncookedseafood products of commercially important species of catfish, snapper, and grouper can be rapidly distinguished from commonly substituted species with a high level of confidence. A tiered testing approach toseafood species verification by sequentially applying a rapid screening method and DNA testing is proposed to more effectively ensure accurate product labeling.
Skin Necrosis with Oculomotor Nerve Palsy Due to a Hyaluronic Acid Filler Injection
Authors: Lee Jae Il , Kang Seok Joo , Sun Hook
Published: July 2017

Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient’s clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection. Our case suggests that surgeons should be aware of nasal vascularity before performing an operation, and that they should avoid injecting fillers at a high pressure and/or in excessive amounts. Additionally, filler injections should be stopped if the patient complains of severe pain, and appropriate measures should be taken to prevent complications caused by intravascular filler injections.

Post-infarction heart failure with preserved ejection fraction (HFpEF) determines a great morbidity and mortality, and given the physiopathology implications of advanced glycation end products (AGEs) in the genesis of myocardial dysfunction. As known endothelial dysfunction is an independent predictor for cardiovascular disease. L-Arginine is the amino acid with potential to improve endothelial function which leading to prevention and treatment of cardiovascular diseases, and we think that L-Arginine may decrease the serum AGEs. We aimed to estimate the value of AGEs in post-infarction HFpEF patients, and detect the effect of L-Arginine on the serum level of AGEs in post-infarction HFpEF pts. all individuals (25) included aged 40 to 80 years, 20(80%) males and 5(20%) females were diagnosed with (HFpEF) according to ESC guidelines (2012), and their functional class according to NYHA classification for HF. 20(80%) patients of them have myocardial infarction in anamnesis. 1st group:13 patients with HFpEF and history of myocardial infarction with L-Arginine added to their standard treatment. 2nd group:7 patients with HFpEF and history of myocardial infarction with standard treatment (without L-Arginine). Comparsion group: 5 patients with HFpEF with standard treatment. We prescribed L. Arginine aspartate (Tivortin 4.2gm) intravenously once daily for 10 days for all 1st group patients. The levels of total cholesterol, triglycerides, glucose, white blood cells, erythrocyte sedimentation rate and AGEs serum level were deterimined. AGEs serum level increased markedly increased in middle-age pts with post infarction HFpEF. Inclusion of L-arginine aspartate in complex of treatment for post infarction HFpEF contributed to the significant decrease AGEs level in >60 years old patients.
ANALYSIS OF STRUCTURAL CHANGES OF CELLULOSE COMPONENT IN PROCESS OF ELEMENTARIZATION OF FLAX FIBERS

Published: July 2017

The comparative research of composition and supramolecular structure of the flax fibers received by methods of a cottonization and a mechanical elementarization under the influence of the cyclic deforming loadings was conducted. It was shown that under the influence of cyclic loadings removal of a considerable part of impurity with the increase in content of cellulose to 80.1% is reached. At the same time, division of complexes onto elementary filament provides the increase in the total surface of material and, as a result, to availability of fibers to the reagents at the subsequent alkaline boiling. X-ray analysis of flax samples with a method of comparison of the normalized parameters of diffraction by crystalline regions of cellulose allowed to establish that degree of crystallinity of a cellulose component of fibers remains constant even at deep purification of raw materials under the influence of cyclic deformations and subsequent boiling. The research of the oriented fibers by X-ray diffraction method has shown that removal of impurity from flax in the course of an elementarization has only weak influence on the sizes of crystallites of cellulose. The increase in the cross sizes of crystallites by 4 – 6% was observed at deep purification of fibers due to the boiling. This phenomenon can be connected with the decrease in influence of a diffraction maximum from impurity on half-width of the equatorial reflex 200 for cellulose Iβ. It should be noted that the longitudinal sizes of crystallites at the same time do not change. It was suggested on possible influence of decrease in content of impurity on supramolecular structure of an amorphous phase of cellulose and as a result on the observed growth of sorption and mechanical properties of flax fibers at an elementarization by method of cyclic deformation.Forcitation:Zavadskii A.E., Stokozenko V.G., Moryganov A.P., Larin I.Yu.

Polyethers are of great interest for various industries due to a complex of valuable properties, such as heat resistance, fire resistance, high strength, etc. Carded polymers occupy a special place among polymers with increased heat resistance, containing in the main polymer chain at least one element that is part of the lateral cyclic grouping. The presence of such fragments increases the glass transition temperature and heat resistance, which allows the copolymers to be operated at higher temperatures without changing the physico-mechanical parameters. For crystalline polymers, the presence of cardo fragments leads to better solubility in organic solvents. One of the promising ways of synthesizing heat-resistant polymeric materials is based on the use of aromatic compounds such as 3,3-bis (4'-hydroxyphenyl) phthalide, 3-chloro-3- (diphenyloxyd-4'-yl) phthalide, 3- chloro-3- (diphenylsulfide-4'-yl) phthalide, 9,9-bis (4'-hydroxyphenyl) fluorene, 9,9-bis (4'-hydroxyphenyl) anthrone-10, 2-phenyl-3,3- Bis (4'-hydroxyphenyl) phthalimidine and the like. At present, the worldwide problem of the release of toxic waste into the environment is aggravated, which causes irreversible climatic changes. To solve this problem, it was proposed to develop solid fuel cells based on polymeric proton-exchange membranes. Thus, polymer membranes must satisfy a number of requirements: to provide minimal ohmic losses, to possess considerable proton conductivity, mechanical strength, thermal stability and to have limited solubility in organic solvents. Polymer membranes with carded fragments in the main chain satisfy all the requirements. In the presented review features of synthesis and properties of copolymers on the basis of polysulfones, polyether ketones, polyetherimides with carded fragments are considered.Forcitation:Shakhmurzova K.T., Kurdanova Zh.I., Zhansitov A.A., Baiykaziev A.E., Khashirova S.Yu., Pakhomov S.I., Ligidov M.Kh.Synthesis and properties of aromatic polyesters whith carded fragments.

Published: July 2017

We consider drawings of graphs that contain dense subgraphs. We introduce intersection-link representations for such graphs, in which each vertex $u$ is represented by a geometric object $R(u)$ and each edge $(u,v)$ is represented by the intersection between $R(u)$ and $R(v)$, if it belongs to a dense subgraph, or by a curve connecting the boundaries of $R(u)$ and $R(v)$, otherwise. We study a notion of planarity, called ${\rm C{\small LIQUE} P{\small LANARITY}}$, for intersection-link representations of graphs in which the dense subgraphs are cliques.
Utility of Regular Radiological Follow-up on Early Detection of Contralateral Malignancy and Long-term Outcomes in Metachronous Bilateral Breast Cancer Patients
Authors: Kim Hyo Sun , Kang Sun Hee
Published: July 2017

Objectives We investigated the utility of regular radiological follow-up on the early detection of contralateral breast cancer(CBC) and prognosis in patients with metachronous bilateral breast cancer. Methods Between 1983 and 2010, 49(2.1%) metachronous bilateral breast cancer patients were identified among a total of 2,343 cases of invasive or in situ breast carcinomas. We reviewed the patients' medical records including age, stage, duration between the first and second breast cancer diagnosis, operation method, recurrence, and breast cancer-specific survival. Results The mean ages at the first and second breast cancer diagnosis were 43.8 and 49.2 years, respectively. The mean duration between the first and second breast cancer diagnosis was 68.9 months (range, 7–266 months). Regular radiological follow-up with annual mammography(MMG) with or without ultrasonography was conducted in 28 patients (63.6%, Group 1), and no regular follow-up was performed in 12 patients (27.3%, Group 2). The median follow-up duration was 150 months. In a comparative analysis, Group 1 patients exhibited more stage 0 and stage 1 malignancies (82.1% vs. 25%, P =0.006) as second cancer and the same or an improved stage (71.4% vs. 33.3%, P =0.042) of second cancer compared to Group 2 patients. Breast cancer-specific survival rates between the two groups after the first cancer occurrence were higher in Group 1 patients compared to Group 2 patients, although this did not reach statistical significance. Conclusion Screening for CBC with regular radiological follow-up could result in early detection of CBC, less invasive surgical procedures, and enhanced breast cancer-specific survival outcomes.

A computed tomography (CT) scan and bronchoscopy were performed to identify the bleeding site. The CT scan revealed pneumonia and a combined hemorrhage in the right-middle and lower lobes. Massive bleeding was detected during the bronchoscopy and emergency embolization was attempted but angiographic findings were normal. An anteriojugulo-right femoral bypass operation was performed to relieve the tortuous and hypertrophied jugular venous obstruction. However, thrombectomy and thrombolysis followed because of graft thrombosis six days post-surgery. The patient was treated with steroid and high-dose cyclophosphamide therapy for his Behçet's disease, which caused the venous obstructions; the saccular bronchial varices in the right-middle and right lower lobes on bronchoscopy regressed slightly after four cycles of cyclophosphamide therapy

La présente recherche, soutenue par le Fonds national suisse (fns), se consacre aux enseignements d’un groupe de didacticiens de
la musique des Hautes écoles de musique (hem) de Genève,
Lausanne, Bâle, Lugano et Berne. Ces enseignements sont appréhendés comme susceptibles
d’éclairer les changements intervenus dans la formation des formateurs et la nature de
l’évolution des dispositifs. Les modes de professionnalisation des futurs enseignants de
musique en fin de formation sont au coeur de cet article. Nous présentons, dans les quatre
parties de cet article : les spécificités de cette recherche, y compris sa méthodologie
mixte (quantitative et qualitative), l’analyse qualitative de modèles professionnels
sous-jacents aux pratiques des formateurs, le corps dans une double fonction (comme outil
pour enseigner et comme objet d’enseignement), les rôles et jeux de rôles inhérents aux
variations didactiques d’un professionnel de l’enseignement.
iReal Pro. Un outil technologique utilisé à des fins didactiques pour soutenir les recommandations de la recherche scientifique dans l’enseignement instrumental
Authors: Rieppi Thomas
Published: July 2017

Cet article propose des façons concrètes d’intégrer à l’enseignement d’instruments de musique des recommandations issues de la recherche scientifique sur l’utilisation des technologies. En fait, il guide les praticiens sur l’utilisation du logiciel iReal Pro à l’aide d’exemples concrets modelés à partir de cours de percussions. Pour terminer, je reviens autour d’observations pédagogiques quant à l’intégration des technologies dans mes leçons de percussion et sur la manière dont leur utilisation a pu remédier, en partie, au décalage mis en avant dans la recherche scientifique.

Ce texte présente l’apport du Service des archives à l’Université de Montréal dans la seconde moitié du XXe siècle dans la mise en place de programmes universitaires en archivistique. Carol Couture, alors directeur du Service, a été l’instigateur du développement de l’enseignement de l’archivistique au sein de l’École de bibliothéconomie et des sciences l’information. Pour se faire, il a notamment mobilisé le Service des archives, fournissant ainsi le personnel enseignant ainsi qu’un milieu de stages, tous indispensables à la formation de nouveaux archivistes.
Paroles inuites
Authors: Duvicq Nelly
Published: July 2017

Parmi les formes littéraires orales, la chanson, chez les Inuits, a toujours été
une pratique générale et variée. Héritière de cette tradition, la chanson inuite
contemporaine du Nunavik a connu un essor important au début des années 1970 et n’a cessé de
se développer depuis. Dans le champ littéraire, les paroles de ces chansons constituent un
corpus important de textes d’une vitalité remarquable au sein desquels les
auteurs-compositeurs explorent des esthétiques variées, naviguent entre les langues et
transmettent une partie de leur culture. En tenant compte du contexte historique, l’auteure
de cet article esquisse une réflexion sur l’évolution formelle de la chanson inuite moderne
et examine les relations que celle-ci entretient avec une forme plus traditionnelle. Enfin,
si le corpus chansonnier ultra-contemporain du Nunavik a pour particularité d’être
trilingue, il révèle néanmoins une recrudescence de textes en inuktitut. Qu’est-ce que cela
signifie sur le plan du discours ?
Les verbes de parole en cri de l’Est
Authors: York Fanny , Collette Vincent , Brousseau Kevin
Published: July 2017

Cet article traite des verbes de parole en cri de l’Est. S’inspirant du cadre théorique développé par Fillmore (1977, 1982) et par Johnson et Fillmore (2000), les auteurs analysent ici les éléments sémantiques du cadre de communication verbale qui sont représentés dans les verbes de parole de cette langue et montrent que la morphologie grammaticale encode le Locuteur et l’Interlocuteur de même que le Message et le Topique. Dans les verbes complexes, un suffixe lexical (appeléfinale concrète) réfère à l’événement de communication tandis que la racine verbale encode le Code, l’état de l’Interlocuteur, le Message et la Manière.
Représentations d’espaces et droits territoriaux autochtones chez les Premières Nations du Canada1
Authors: Le Roy Étienne
Published: July 2017

La participation de l’auteur, depuis une trentaine d’années, à divers programmes canadiens mettant en jeu le rapport au droit en situation coloniale et post-coloniale a débouché sur une invitation à se joindre au programme « Peuples autochtones et gouvernance » pour y travailler sur la question des revendications territoriales des Premières Nations du Canada et tenter de remédier à leur aporie. D’un point de vue anthropologique, les rapports des autochtones aux territoires sont dominés par une représentation de l’espace « odologique », comme science des cheminements privilégiant une appropriation des ressources (fruits au sens juridique) là où le droit civil ou la common law reposent sur une approche « géométrique » et sur la propriété du fonds. Des perspectives judiciaires nouvelles semblent ainsi envisageables. L’auteur présente ici le cadre théorique général de la démarche, laissant à des collègues québécois le loisir d’en apprécier l’applicabilité.
Structure sociale et ordres juridiques originels dans l’Outaouais supérieur et les régions voisines
Authors: Leroux Jacques
Published: July 2017

Cet article fait un retour sur des thèses classiques en recherche algonquiniste en noyautant la réflexion autour des conceptions de la bande déjà proposées. Il présente d’abord un bref aperçu de recherches antérieures sur une application de la théorie des maîtrises foncières et fruitières où les concepts de bande locale et de bande régionale ont été utilisés et il pose à nouveau le problème de leur définition en reprenant à Edward S. Rogers un questionnement sur des notions afférentes. En prenant pour modèle une classification de niveaux d’interactions sociales proposée par Eleanor Leacock, l’auteur tente d’illustrer la configuration de la maisonnée multifamiliale en se reportant à un récit d’« hivernement » du Père Paul Lejeune, en vue de dégager certains paramètres de conduites sociales caractérisées par l’esprit du don. La mythologie est convoquée pour témoigner de cet esprit chez les Algonquins de l’Outaouais supérieur, pour ensuite servir d’amorce au développement d’une hypothèse sur la bonne distance à établir pour se trouver un conjoint dans le cadre des relations matrimoniales. L’auteur interroge ensuite l’emploi des mots « quartier » et « district » qui auraient désigné des espaces de maîtrises foncières et fruitières étayant les rapports de collaboration entre les membres d’une unité que Leacock appelait « bande d’hiver ».

Diversity of T cell receptor (TCR) repertoires, generated by somatic DNA rearrangements, is central to immune system function. However, the level of sequence similarity of TCR repertoires within and between species has not been characterized. Using network analysis of high-throughput TCR sequencing data, we found that abundant CDR3-TCRβ sequences were clustered within networks generated by sequence similarity. We discovered a substantial number of public CDR3-TCRβ segments that were identical in mice and humans. These conserved public sequences were central within TCR sequence-similarity networks. Annotated TCR sequences, previously associated with self-specificities such as autoimmunity and cancer, were linked to network clusters. Mechanistically, CDR3 networks were promoted by MHC-mediated selection, and were reduced following immunization, immune checkpoint blockade or aging. Our findings provide a new view of T cell repertoire organization and physiology, and suggest that the immune system distributes its TCR sequences unevenly, attending to specific foci of reactivity.

The death-associated protein kinase 1 (DAPK1) can act as an oncogene or a tumor suppressor gene depending on the cellular context as well as external stimuli. Our study aims to investigate the prognostic significance of DAPK1 in liver cancer in both mRNA and protein levels. The mRNA expression of DAPK1 was extracted from the Gene Expression Omnibus database in three independent liver cancer datasets while protein expression of DAPK1 was detected by immunohistochemistry in our Chinese liver cancer patient cohort. The associations between DAPK1 expression and clinical characteristics were tested. DAPK1 mRNA expression was down-regulated in liver cancer. Low levels of DAPK1 mRNA were associated with shorter survival in a liver cancer patient cohort (n = 115; p = 0.041), while negative staining of DAPK1 protein was significantly correlated with shorter time to progression (p = 0.002) and overall survival (p = 0.02). DAPK1 was an independent prognostic marker for both time to progression and overall survival by multivariate analysis. Liver cancer with the b-catenin mutation has a lower DAPK1 expression, suggesting that DAPK1 may be regulated under the b-catenin pathway. In addition, we also identified genes that are co-regulated with DAPK1. DAPK1 expression was positively correlated with IRF2, IL7R, PCOLCE and ZBTB16, and negatively correlated with SLC16A3 in both liver cancer datasets. Among these genes, PCOLCE and ZBTB16 were significantly down-regulated, while SLC16A3 was significantly upregulated in liver cancer. By using connectivity mapping of these co-regulated genes, we have identified amcinonide and sulpiride as potential small molecules that could potentially reverse DAPK1/PCOLCE/ZBTB16/SLC16A3 expression. Our study demonstrated for the first time that both DAPK1 mRNA and protein expression levels are important prognostic markers in liver cancer, and have identified genes that may contribute to DAPK1-mediated liver carcinogenesis.
