Published: May 2017

Background: We used administrative health data to explore the impact of primary care physician (pcp) visits on acute-care service utilization by women receiving adjuvant chemotherapy for early-stage breast cancer (ebc). Methods: Our population-based retrospective cohort study examined pcp visits and acute-care use [defined as an emergency room (er) visit or hospitalization] by women diagnosed with ebc between 2007 and 2009 and treated with adjuvant chemotherapy. Multivariate regression analysis was used to identify the effect of pcp visits on the likelihood of experiencing an acute-care visit. Results: Patients receiving chemotherapy visited a pcp significantly more frequently than they had before their diagnosis [relative risk (rr): 1.48; 95% confidence interval (ci): 1.44 to 1.53; p < 0.001] and significantly more frequently than control subjects without cancer (rr: 1.51; 95% ci: 1.46 to 1.57; p < 0.001). More than one third of pcp visits by chemotherapy patients were related to breast cancer or chemotherapy-related side effects. In adjusted multivariate analyses, the likelihood of experiencing an er visit or hospitalization increased in the days immediately after a pcp visit (rr: 1.92; 95% ci: 1.76 to 2.10; p < 0.001). Conclusions: During chemotherapy treatment, patients visited their pcp more frequently than control subjects did, and they visited for reasons related to their breast cancer or to chemotherapy-related side effects. Visits to a pcp by patients receiving chemotherapy were associated with an increased frequency of er visits or hospitalizations in the days immediately after the pcp visit. Those results suggest an opportunity to institute measures for early detection and intervention in chemotherapy side effects.

Introduction: Oncologists have traditionally been responsible for providing routine follow-up care for cancer survivors; in recent years, however, primary care providers (pcps) are taking a greater role in care during the follow-up period. In the present study, we used a longitudinal multi-province retrospective cohort study to examine how primary care and specialist care intersect in the delivery of breast cancer follow-up care. Methods: Various databases (registry, clinical, and administrative) were linked in each of four provinces: British Columbia, Manitoba, Ontario, and Nova Scotia. Population-based cohorts of breast cancer survivors were identified in each province. Physician visits were identified using billings or claims data and were classified as visits to primary care (total, breast cancer–specific, and other), oncology (medical oncology, radiation oncology, and surgery), and other specialties. The mean numbers of visits by physician type and specialty, or by combinations thereof, were examined. The mean numbers of visits for each follow-up year were also examined by physician type. Results: The results showed that many women (>64%) in each province received care from both primary care and oncology providers during the follow-up period. The mean number of breast cancer–specific visits to primary care and visits to oncology declined with each follow-up year. Interprovincial variations were observed, with greater surgeon follow-up in Nova Scotia and greater primary care follow-up in British Columbia. Provincial differences could reflect variations in policies and recommendations, relevant initiatives, and resources or infrastructure to support pcp-led follow-up care. Conclusions: Optimizing the role of pcps in breast cancer follow-up care might require strategies to change attitudes about pcp-led follow-up and to better support pcps in providing survivorship care.

The aging of the Canadian population represents the major risk factor for a projected increase in cancer incidence in the coming decades. However, the evidence base to guide management of older adults with cancer remains extremely limited. It is thus imperative that we develop a national research agenda and establish a national collaborative network to devise joint studies that will help to accelerate the development of high-quality research, education, and clinical care and thus better address the needs of older Canadians with cancer. To begin this process, the inaugural meeting of the Canadian Network on Aging and Cancer was held in Toronto, 27 April 2016. The meeting was attended by 51 invited researchers and clinicians from across Canada, as well as by international leaders in geriatric oncology from the United States and France. The objectives of the meeting were to (1) review the present landscape of education, clinical care, and research in the area of cancer and aging in Canada; (2) identify issues of high research priority in Canada within the field of cancer and aging; (3) identify current barriers to geriatric oncology research in Canada and develop potential solutions; (4) develop a Canadian collaborative multidisciplinary research network between investigators to improve health outcomes for older adults with cancer; (5) learn from successful international efforts to stimulate the geriatric oncology research agenda in Canada. In the present report, we describe the education, clinical care, and research priorities that were identified at the meeting.
How Different Is Cancer Control across Canada? Comparing Performance Indicators for Prevention, Screening, Diagnosis, and Treatment
Authors: Rahal R. , Chadder J. , DeCaria K. , Lockwood G. , Bryant H.
Published: May 2017

Meaningful performance measures are an important part of the toolkit for health system improvement. The Canadian Partnership Against Cancer has been reporting on pan-Canadian cancer system performance indicators since 2009—work that has led to the availability of standardized measures that can help to shed light on the extent of variation and opportunities for quality improvement across the country. Those measures include a core set of system indicators ranging from prevention and screening, through diagnosis and treatment, to survivorship and end-of-life care. Key indicators were calculated and graphed, showing the range from worst to best result for the provinces and territories included in the data. There were often significant differences in cancer system performance between provinces and territories. For example, smoking prevalence rates ranged from 14% to 62%. The 90th percentile wait times from an abnormal breast screen to resolution (without biopsy) ranged from 4 weeks to 8 weeks. The percentage of breast cancer resections that used breast-conserving surgery rather than mastectomy ranged from 38% to 75%. Clinical trial participation rates for adults ranged from 0.2% to 6.6%. Variations in performance indicators between Canadian jurisdictions suggest potential differences in the planning and delivery of cancer control services and in clinical practice patterns and patient outcomes. Understanding sources of variation can help to identify opportunities for improvements in the quality and outcomes of cancer control service delivery in each province and territory.

Cervical Vestibular Evoked Myogenic Potential in Hypoglossal Nerve Schwannoma: A Case Report
Authors: Rajasekaran Aravind Kumar , Savardekar Amey Rajan , Shivashankar Nagaraja Rao
Published: May 2017

Background:Schwannoma of the hypoglossal nerve is rare. This case report documents an atypical abnormality of the cervical vestibular evoked myogenic potential (cVEMP) in a patient with schwannoma of the hypoglossal nerve. The observed abnormality was attributed to the proximity
of the hypoglossal nerve to the spinal accessory nerve in the medullary cistern and base of the skull.Purpose:To report cVEMP abnormality in a patient with hypoglossal nerve schwannoma and provide an anatomical correlation for this abnormality.Research Design:Case report.Study
Sample:A 44-yr-old woman.Data Collection:Pure-tone and speech audiometry, tympanometry, acoustic stapedial reflex, auditory brainstem response, and cVEMP testing were performed.Results:The audiological test results were normal except for the absence of cVEMP on the lesion
side (right).Conclusions:A cVEMP abnormality indicating a compromised spinal accessory nerve was observed in a patient with hypoglossal nerve schwannoma. This case report highlights the importance of recording cVEMP in relevant neurological conditions and provides clinical proof for
the involvement of the spinal accessory nerve in the vestibulocollic reflex pathway.
Predictive Accuracy of Sweep Frequency Impedance Technology in Identifying Conductive Conditions in Newborns
Authors: Aithal Venkatesh , Kei Joseph , Driscoll Carlie , Murakoshi Michio , Wada Hiroshi
Published: May 2017

Background:Diagnosing conductive conditions in newborns is challenging for both audiologists and otolaryngologists. Although high-frequency tympanometry (HFT), acoustic stapedial reflex tests, and wideband absorbance measures are useful diagnostic tools, there is performance
measure variability in their detection of middle ear conditions. Additional diagnostic sensitivity and specificity measures gained through new technology such as sweep frequency impedance (SFI) measures may assist in the diagnosis of middle ear dysfunction in newborns.Purpose:The purpose
of this study was to determine the test performance of SFI to predict the status of the outer and middle ear in newborns against commonly used reference standards.Research Design:Automated auditory brainstem response (AABR), HFT (1000 Hz), transient evoked otoacoustic emission (TEOAE),
distortion product otoacoustic emission (DPOAE), and SFI tests were administered to the study sample.Study Sample:A total of 188 neonates (98 males and 90 females) with a mean gestational age of 39.4 weeks were included in the sample. Mean age at the time of testing was 44.4 hr.Data
Collection and Analysis:Diagnostic accuracy of SFI was assessed in terms of its ability to identify conductive conditions in neonates when compared with nine different reference standards (including four single tests [AABR, HFT, TEOAE, and DPOAE] and five test batteries [HFT + DPOAE, HFT
+ TEOAE, DPOAE + TEOAE, DPOAE + AABR, and TEOAE + AABR]), using receiver operating characteristic (ROC) analysis and traditional test performance measures such as sensitivity and specificity.Results:The test performance of SFI against the test battery reference standard of HFT + DPOAE
and single reference standard of HFT was high with an area under the ROC curve (AROC) of 0.87 and 0.82, respectively. Although the HFT + DPOAE test battery reference standard performed better than the HFT reference standard in predicting middle ear conductive conditions in neonates, the difference
in AROC was not significant. Further analysis revealed that the highest sensitivity and specificity for SFI (86% and 88%, respectively) was obtained when compared with the reference standard of HFT + DPOAE. Among the four single reference standards, SFI had the highest sensitivity and specificity
(76% and 88%, respectively) when compared against the HFT reference standard.Conclusions:The high test performance of SFI against the HFT and HFT + DPOAE reference standards indicates that the SFI measure has appropriate diagnostic accuracy in detection of conductive conditions in newborns.
Hence, the SFI test could be used as adjunct tool to identify conductive conditions in universal newborn hearing screening programs, and can also be used in diagnostic follow-up assessments.
Higher Asymmetry Ratio and Refixation Saccades in Individuals with Motion Sickness
Authors: Neupane Anuj Kumar , Gururaj Krithika , Sinha Sujeet Kumar
Published: May 2017

Background:Motion sickness is a complex autonomic phenomenon caused by the intersensory conflict among the balancing systems, resulting in a mismatch of signals between static physical conditions of the susceptible individual exposed to dynamic environment.Purpose:The
present study was done to assess the sacculocollic reflex pathway and six semicircular canals in individuals susceptible to motion sickness.Research Design:Standard group comparison was used.Study Sample:A total of 60 participants with an age range of 17‐25 yr were included,
where group I comprised 30 participants with motion sickness and group II comprised 30 participants without motion sickness. The Motion Sickness Susceptibility Questionnaire‐Short was administered to classify the participants into groups with or without motion sickness.Data Collection
and Analysis:The cervical vestibular-evoked myogenic potential (cVEMP) test and video head impulse test (vHIT) were administered to all participants. The Shapiro‐Wilk test revealed normal distribution of the data (p > 0.05). Hence a parametric independent sample t
test was done to check significant difference in cVEMP and vHIT parameters between the two groups.Results:The present study revealed no significant difference for cVEMP latencies and amplitude in individuals with motion sickness. However, significantly higher cVEMP asymmetry ratio was
observed in individuals with motion sickness. Though the vestibulo-ocular reflex (VOR) gain values showed no significant difference between the two groups except for the right anterior left posterior plane, the asymmetry in VOR gain values revealed significant difference between the groups,
suggesting asymmetry as a better parameter than absolute VOR gain values. Also, the presence of refixation saccades in 100% of the individuals with motion sickness accorded with various studies reported earlier with vestibular-related pathologies.Conclusions:Presence of higher asymmetry
ratio in cVEMP and vHIT test results plus refixation saccades to stabilize the gaze in vHIT can suggest some amount of vestibular anomalies in individuals with motion sickness.

Authors: Pathak Rajesh , Mitra Amarnath
Published: May 2017

The purpose of this study is to examine the presence of volatility smirk anomaly in index options and its predictability for future returns. The study tests the temporal properties of volatility smirk and further explores the factors determining the anomaly. The daily volatility smirk is computedfor the period 2004–2014 and the first lag of smirk is used in generalized least square (GLS) estimation framework, with set of control variables in two different specifications, to test the predictability as well as the determinants of volatility smirk. The study reports significant presence of volatility smirk in index options with an auto–regressive structure. Smirk predicts marginal returns and the predictability is robust to the control of major risk factors. It is also found that open interest of calls and puts, along with market risk premium and momentum premium, act as significant predictor of volatility smirk. The results are helpful in enhancing returns on investment in Index based funds and designing options strategies from the perspective of volatility risk. The study is first of its kind in the Indian market examining the reasons and consequences of existence of volatility smirk in index options.
E-SERVICES IN BUSINESS MODELS OF ENTERPRISES IN THE LOGISTICS SECTOR
Authors: Dębkowska Katarzyna
Published: May 2017

Most of the available papers on the logistics sector identify the type of the business model with the type of logistics service providers, distinguishing between three to five business models. These models most often focus, almost exclusively on the complexity of the logistical services and their scope. The more complex a logistic service is, the more benefits it brings to the company. This is a result of the increase in added value and key competences, and a decrease in the intensity of resources usage. Expanding logistics services to include e-services significantly improves the position of a company in the so-called pyramid of logistics services. The purpose of this article is to identify the use of e-services among the enterprises of the logistics sector and to examine the impact of the use of e-services on the quality of the business model. The realization of the objective was possible thanks to a study carried out among the logistics sector companies that participated in the twentieth edition of the Polish ranking of enterprises in the logistics sector. The analysis of the data from the concluded study was conducted with the use of the methods of multivariate statistical analysis: cluster analysis and correspondence analysis. The carried out study of selected companies of the logistics sector leads to the conclusion that the use of e-services in their offer has a positive effect on the quality of the business model. Offering e-services adds value for the customer, as well as the value for the company, as evidenced by the improved financial condition of enterprises that use e-logistics.
Cyclic Period Oscillation of the Eclipsing Dwarf Nova DV UMa
Authors: Han Z.-T , Qian S.-B , Irina Voloshina , Zhu L.-Y
Published: May 2017

DV UMa is an eclipsing dwarf nova with an orbital period of ∼2.06 hr, which lies just at the bottom edge of the period gap. To detect its orbital period changes, we present 12 new mid-eclipse times by using our CCD photometric data and archival data. The latest version of the O–C diagram, combined with the published mid-eclipse times in quiescence, and spanning ∼30 years, was obtained and analyzed. The best fit to those available eclipse timings shows that the orbital period of DV UMa is undergoing a cyclic oscillation with a period of

years and an amplitude of

s. The periodic variation most likely arises from the light-travel-time effect via the presence of a circumbinary object, because the required energy to drive the Applegate mechanism is too high in this system. The mass of the unseen companion was derived as

. If the third body is in the orbital plane (i.e.,

) of the eclipsing pair, this would indicate it is a brown dwarf. This hypothetical brown dwarf is orbiting its host star at a separation of ∼8.6 au in an eccentric orbit (e = 0.44).

Swift monitoring of NGC 4151 with an ∼6 hr sampling over a total of 69 days in early 2016 is used to construct light curves covering five bands in the X-rays (0.3–50 keV) and six in the ultraviolet (UV)/optical (1900–5500 Å). The three hardest X-ray bands (>2.5 keV) are all strongly correlated with no measurable interband lag, while the two softer bands show lower variability and weaker correlations. The UV/optical bands are significantly correlated with the X-rays, lagging ∼3–4 days behind the hard X-rays. The variability within the UV/optical bands is also strongly correlated, with the UV appearing to lead the optical by ∼0.5–1 days. This combination of ≳3 day lags between the X-rays and UV and ≲1 day lags within the UV/optical appears to rule out the “lamp-post” reprocessing model in which a hot, X-ray emitting corona directly illuminates the accretion disk, which then reprocesses the energy in the UV/optical. Instead, these results appear consistent with the Gardner & Done picture in which two separate reprocessings occur: first, emission from the corona illuminates an extreme-UV-emitting toroidal component that shields the disk from the corona; this then heats the extreme-UV component, which illuminates the disk and drives its variability.

We study the writhe, twist, and magnetic helicity of different magnetic flux ropes, based on models of the solar coronal magnetic field structure. These include an analytical force-free Titov–Démoulin equilibrium solution, non-force-free magnetohydrodynamic simulations, and nonlinear force-free magnetic field models. The geometrical boundary of the magnetic flux rope is determined by the quasi-separatrix layer and the bottom surface, and the axis curve of the flux rope is determined by its overall orientation. The twist is computed by the Berger–Prior formula, which is suitable for arbitrary geometry and both force-free and non-force-free models. The magnetic helicity is estimated by the twist multiplied by the square of the axial magnetic flux. We compare the obtained values with those derived by a finite volume helicity estimation method. We find that the magnetic helicity obtained with the twist method agrees with the helicity carried by the purely current-carrying part of the field within uncertainties for most test cases. It is also found that the current-carrying part of the model field is relatively significant at the very location of the magnetic flux rope. This qualitatively explains the agreement between the magnetic helicity computed by the twist method and the helicity contributed purely by the current-carrying magnetic field.
X-Ray-induced Deuterium Enrichment of N-rich Organics in Protoplanetary Disks: An Experimental Investigation Using Synchrotron Light

The deuterium enrichment of organics in the interstellar medium, protoplanetary disks, and meteorites has been proposed to be the result of ionizing radiation. The goal of this study is to simulate and quantify the effects of soft X-rays (0.1–2 keV), an important component of stellar radiation fields illuminating protoplanetary disks, on the refractory organics present in the disks. We prepared tholins, nitrogen-rich organic analogs to solids found in several astrophysical environments, e.g., Titan’s atmosphere, cometary surfaces, and protoplanetary disks, via plasma deposition. Controlled irradiation experiments with soft X-rays at 0.5 and 1.3 keV were performed at the SEXTANTS beamline of the SOLEIL synchrotron, and were immediately followed by ex-situ infrared, Raman, and isotopic diagnostics. Infrared spectroscopy revealed the preferential loss of singly bonded groups (N–H, C–H, and R–N≡C) and the formation of sp3 carbon defects with signatures at ∼1250–1300 cm−1. Raman analysis revealed that, while the length of polyaromatic units is only slightly modified, the introduction of defects leads to structural amorphization. Finally, tholins were measured via secondary ion mass spectrometry to quantify the D, H, and C elemental abundances in the irradiated versus non-irradiated areas. Isotopic analysis revealed that significant D-enrichment is induced by X-ray irradiation. Our results are compared to previous experimental studies involving the thermal degradation and electron irradiation of organics. The penetration depth of soft X-rays in μm-sized tholins leads to volume rather than surface modifications: lower-energy X-rays (0.5 keV) induce a larger D-enrichment than 1.3 keV X-rays, reaching a plateau for doses larger than 5 × 1027 eV cm−3. Synchrotron fluences fall within the expected soft X-ray fluences in protoplanetary disks, and thus provide evidence of a new non-thermal pathway to deuterium fractionation of organic matter.
Magnetohydrodynamic Modeling of Solar Coronal Dynamics with an Initial Non-force-free Magnetic Field
Authors: Prasad A. , Bhattacharyya R. , Kumar Sanjay
Published: May 2017

The magnetic fields in the solar corona are generally neither force-free nor axisymmetric and have complex dynamics that are difficult to characterize. Here we simulate the topological evolution of solar coronal magnetic field lines (MFLs) using a magnetohydrodynamic model. The simulation is initialized with a non-axisymmetric non-force-free magnetic field that best correlates with the observed vector magnetograms of solar active regions (ARs). To focus on these ideas, simulations are performed for the flaring AR 11283 noted for its complexity and well-documented dynamics. The simulated dynamics develops as the initial Lorentz force pushes the plasma and facilitates successive magnetic reconnections at the two X-type null lines present in the initial field. Importantly, the simulation allows for the spontaneous development of mass flow, unique among contemporary works, that preferentially reconnects field lines at one of the X-type null lines. Consequently, a flux rope consisting of low-lying twisted MFLs, which approximately traces the major polarity inversion line, undergoes an asymmetric monotonic rise. The rise is attributed to a reduction in the magnetic tension force at the region overlying the rope, resulting from the reconnection. A monotonic rise of the rope is in conformity with the standard scenario of flares. Importantly, the simulated dynamics leads to bifurcations of the flux rope, which, being akin to the observed filament bifurcation in AR 11283, establishes the appropriateness of the initial field in describing ARs.

We construct the most complete sample of supernova remnants (SNRs) in any galaxy—the Large Magellanic Cloud (LMC) SNR sample. We study their various properties such as spectral index (α), size, and surface brightness. We suggest an association between the spatial distribution and environment density of LMC SNRs, and their tendency to be located around supergiant shells. We find evidence that the 16 known type Ia LMC SNRs are expanding in a lower density environment compared to the Core-Collapse (CC) type. The mean diameter of our entire population (74) is 41 pc, which is comparable to nearby galaxies. We did not find any correlation between the type of SN explosion, ovality, or age. The

relationship with slope a = 0.96 implies that the randomized diameters are readily mimicking such an exponent. The rate of SNe occurring in the LMC is estimated to be ∼1 per 200 yr. The mean α of the entire LMC SNR population is −0.52, which is typical of most SNRs. However, our estimates show a clear flattening of the synchrotron α as the remnants age. As predicted, the CC SNRs in our sample are significantly brighter radio emitters than type Ia remnants. We also estimate the

relation for the LMC to have a slope ∼3.8, which is comparable with other nearby galaxies. We also find the residency time of electrons in the galaxy (4.0–14.3 Myr), implying that SNRs should be the dominant mechanism for the production and acceleration of CRs.
Uma análise da família através do personagem Felix, de Amor à Vida: possíveis relações entre Comunicação/Educação e a telenovela
Authors: Da Costa Rocha Camilla Rodrigues Netto
Published: May 2017

Partimos do debate ainda restrito na sociedade brasileira acerca do que se constitui como família. Isso porque, atualmente, convivemos com diretrizes opostas: a aprovação legislativa em caráter parcial – somente na Câmara – do Estatuto da Família, que restringe família à união formada por homem e mulher, e decisões do STF e do CNJ em sentido contrário, que albergam a união de casais homoafetivos. Identificando esse debate em torno da família na novela Amor à Vida e tendo em vista que a proposição de sentidos pelos media não se dá de modo isento, nem tampouco despido de estereótipos, buscamos compreender em que medida a narrativa teleficcional permite a construção de novos sentidos por parte dos sujeitos, por meio de seu consumo. E, ainda, introduzimos o campo da comunicação/educação como locus privilegiado de discussão da telenovela com possibilidade para reflexões que ampliem os horizontes e esvaziem os determinismos. Para tanto, nos valemos de pesquisa bibliográfica a partir dos autores Baccega, Martín-Barbero, Rey, Lopes, Sunkel, Canclini e Slater.
Visibilidades midiáticas e transgeneridade: apontamentos sobre um estudo de caso com Laerte Coutinho
Authors: Theodoro Hadriel
Published: May 2017

As pessoas transgêneras enfrentam reiteradamente as normas regulatórias do gênero e da sexualidade, que são pautadas em marcos binários. Ao transgredi-las, ficam suscetíveis a uma infinidade de violências simbólicas e/ou físicas, incluindo uma invisibilidade e um emudecimento radicais. Como essas violências lhes privam de um pleno exercício da cidadania, acabam por incidir no modo como suas existências sociais são (ou não) legitimadas. Levando isso em consideração, o objetivo principal deste artigo é estabelecer algumas ponderações teóricas, epistemológicas e metodológicas acerca das visibilidades midiáticas das pessoas transgêneras, a partir de um estudo com Laerte Coutinho.

Este artigo congrega duas pesquisas com objetivos diferentes, mas que se complementam de forma analítica. Uma já finalizada, que trabalhou as narrativas dos colecionadores de Revista em Quadrinhos na cidade de São Paulo e a outra, em desenvolvimento, que reflete sobre juventude, redes digitais e práticas do consumo. Tem como objetivo pensar a importância das narrativas para a construção das identidades e subjetividades juvenis na cultura Nerd, no Brasil, assim como, o processo de difusão e consumo de elementos advindos dessa cultura. Constatamos que as narrativas são fundamentais nesses processos, pois participam da edificação de um sofisticado sistema de Universos. Concluímos que é por meio desse “sistema” que as juventudes Nerds, no Brasil, (re)constroem identidades individuais, coletivas e culturais.

« Tenir sur le Rhin ».Les mouvements de jeunesse d’Alsace pendant la Deuxième Guerre mondiale
Authors: Fuchs Julien
Published: May 2017

L’histoire des mouvements de jeunesse alsaciens pendant la Deuxième Guerre mondiale est loin d’être lisse. Mais bien qu’elle s’inscrive dans deux espaces différents, à la fois en Alsace et dans les régions où s’exilent les Alsaciens, cette histoire révèle une orientation commune de ces groupements. Interdits en Alsace par les autorités nazies, et de plus en plus muselés en France par le régime de Vichy, ces mouvements demeurent des interstices de liberté pour les Alsaciens qui y participent. Moyens d’entretenir une vie ordinaire de jeunes, de cultiver un sentiment d’appartenance à l’Alsace, ils sont aussi des lieux d’engagement contre l’oppression, et pour certains, les terreaux d’une entrée en résistance. Beaucoup de ceux qui y ont pris part deviendront des figures importantes de la reconstruction de l’Alsace après 1944.

Si la centralité du diplôme dans le processus de recrutement et d’évolution du début de carrière est une affaire de bon sens, elle est plus difficile à accepter – voire à être perçue comme un motif de discrimination – lorsqu’elle perdure tout au long de la carrière, et notamment quand il s’agit d’accéder aux postes de direction d’une organisation, puisqu’on devrait plutôt s’attendre à ce que seules les compétences et performances soient prises en compte à ce stade. S’il est particulièrement difficile de mesurer l’impact socio-économique d’un système dans lequel les diplômés des grandes écoles ont un accès prioritaire aux fonctions dirigeantes des entreprises, il est en revanche plus aisé d’analyser, à un niveau individuel, le rôle joué par le diplôme dans la trajectoire des salariés. C’est cette question qui est soulevée dans le cadre d’une entreprise qui accorde de l’importance aux diplômes de prestige : le groupe Orange. Cette étude de cas montre que l’attitude des salariés face à l’accès privilégié des diplômés de grandes écoles aux postes de direction, n’est pas nécessairement négative et que les salariés qui « réussissent » malgré un diplôme de rang 2 ont mis en œuvre des mécanismes de compensations spécifiques telles que des compétences spécialisées, une forte mobilité géographique ou un travail en mode projet.
Troubles dans le féminisme
Authors: Guionnet Christine
Published: May 2017

Les sondages d’opinion se succèdent régulièrement pour insister sur l’image négative, aujourd’hui attachée à un certain type de féminisme. Pourtant, ces mêmes sondages montrent que certaines valeurs portées par le féminisme sont toujours considérées comme importantes par une majorité de sondés. Ce trouble dans le féminisme est-il visible sur la toile ? Pour le savoir, nous avons choisi d’analyser des discussions entre internautes sur des sites non militants, notre objectif consistant à analyser les réappropriations ordinaires du féminisme et de l’antiféminisme par des citoyens non engagés. Nous montrons combien les forums observés contribuent à mettre en exergue une « zone grise » de réappropriations citoyennes brouillant les frontières entre féminisme et antiféminisme. Internet accentue, à cet égard, le trouble dans le féminisme.
Négocier l’action publique dans un État sous régime d’aide : une analyse comparée des politiques de l’enseignement supérieur et du foncier en Tanzanie
Authors: Provini Olivier , Schlimmer Sina
Published: May 2017

Depuis le milieu des années 1970, la Tanzanie fait l’objet d’une attention toute particulière de la communauté internationale en captant la plus grande part d’aide au développement de l’Afrique subsaharienne. Cette donnée empirique a suscité l’intérêt de nombreux chercheurs et experts internationaux qui construisent la Tanzanie comme un « donor darling ». Pourtant, ces études omettent les impacts de cette économie politique singulière sur le processus de l’action publique. L’objectif de notre article est, à travers une étude sectorialisée et comparative originale, d’appréhender les conséquences de ces réseaux internationaux d’acteurs sur la fabrique des politiques publiques. En s’appuyant sur les processus de politiques publiques dans les secteurs de l’enseignement supérieur et du foncier, nous postulons que cette articulation doit s’effectuer par une approche socio-historique de l’État tanzanien. En partant des résultats de la littérature qui conclut généralement un contournement de l’État (privatisation des universités, accaparement des terres), nous démontrons que l’action publique, négociée et historicisée, participe à la formation de l’État.
Les Kosmiker

Illuministes et théosophes posent au XVIII e  siècle les bases nouvelles d’une cosmologie conjuguant l’énergétique héraclitéenne et l’émersion parménidienne. Cette entreprise est notamment guidée par le Sensorium Dei de Franz von Baader, un nouvel âge de la nature qui est réapproprié par les Naturphilosophes au Stift de Tübingen, en particulier Hölderlin, Schelling et Hegel, ouvrant sur une astrologie intérieure, une météosensibilité et les démons du paganisme. Ces trois thématiques vont alimenter la bohème européenne, des Mardis de Mallarmé au Cercle cosmique de Schwabing. Les cultes dionysiens qui y sont célébrés composent alors le terreau des utopies communautaires qui se déploient de Monte Verità à la Beat Generation.
Géographie de l’intime, habitabilité et cosmogonies immersives
Authors: Falaix Ludovic
Published: May 2017

Cet article présente l’habitabilité comme possibilité pour les individus de s’emparer du génie des lieux, de transformer le chaos en cosmos, pour éprouver leur être au monde. Fort de cette hypothèse qui consiste à penser que l’avènement de l’espace témoigne d’une appropriation sensible des lieux par les individus, cet article circonscrit ainsi les enjeux d’une géographie de l’intime. Définie comme l’interprétation des ressorts émotionnels et sensoriels que convoquent les individus pour élaborer leurs territorialités, c’est-à-dire pour opérer la mutation du lieu en espace dans une perspective ontologique, la géographie de l’intime entend ainsi concourir à l’exploration des raisons pour lesquelles les individus s’abandonnent dans de nouvelles formes de récréativité immersive qui redessinent les contours du rapport de l’homme à la nature. Enfin, ces expériences corporelles immersives qui consistent à exalter une forme de bien-être existentiel fondé sur la dimension transcendantale que recouvre le processus de cosmogonisation appellent également à interroger la place du corps dans les analyses en géographie.
Médée Fukushima
Authors: Moreau Yoann
Published: May 2017

La part radioactive de Fukushima n’est pas spectaculaire mais spectrale. Nous faisons l’hypothèse que son impact symbolique – la peur et les angoisses engendrées par la radioactivité – ont plus d’impact que sa part mesurable et rationnelle. Peut-on l’appréhender à partir d’une dramaturgie et d’une épistémologie classiques ? Face aux catastrophes, quelle est la pertinence des mythes ?
Un enfant ou un emploi ? Dilemme des Allemandes de l’Est et de l’Ouest
Authors: Kreyenfeld Michaela , Konietzka Dirk
Published: May 2017

En Allemagne de l’Est, avant la réunification, moins de 10 % des femmes n’avaient pas d’enfants, tandis qu’en Allemagne de l’Ouest leur nombre avait augmenté régulièrement pour atteindre plus de 20 %. Cet article s’intéresse à cette évolution divergente en s’appuyant sur les données d’un micro-recensement. Il étudie les politiques sociales qui ont influencé l’emploi des femmes et les modèles familiaux avant la réunification. Il aborde aussi d’autres tendances et réformes plus récentes, et notamment le développement de l’accueil des jeunes enfants et la réforme de l’allocation de congé parental en 2007. Si les modèles familiaux et les régimes d’emploi ont eu tendance à s’aligner dans l’est et l’ouest de l’Allemagne réunifiée, des différences de comportement subsistent. Aujourd’hui encore, il est plus courant pour une femme de ne pas avoir d’enfants dans l’ouest que dans l’est du pays. En outre, les femmes est-allemandes travaillent en règle générale à temps plein, tandis que le taux de mères ouest-allemandes qui travaillent à temps plein n’augmente que progressivement.
Virtual Gaming Simulation in Nursing Education: A Focus Group Study
Authors: Verkuyl Margaret , Hughes Michelle , Tsui Joyce , Betts Lorraine , St-Amant Oona , Lapum Jennifer L.
Published: May 2017

Background:

The use of serious gaming in a virtual world is a novel pedagogical approach in nursing education. A virtual gaming simulation was implemented in a health assessment class that focused on mental health and interpersonal violence. The study's purpose was to explore students' experiences of the virtual gaming simulation.

Method:

Three focus groups were conducted with a convenience sample of 20 first-year nursing students after they completed the virtual gaming simulation.

Results:

Analysis yielded five themes: (a) Experiential Learning, (b) The Learning Process, (c) Personal Versus Professional, (d) Self-Efficacy, and (e) Knowledge.

Conclusion:

Virtual gaming simulation can provide experiential learning opportunities that promote engagement and allow learners to acquire and apply new knowledge while practicing skills in a safe and realistic environment. [

Harlequin-Inspired Story-Based Learning: An Educational Innovation for Pediatric Nursing Communication
Authors: Shaw Alison , Lind Candace , Ewashen Carol
Published: May 2017

Background:

Effective communication with patients and families is essential for quality care in the pediatric environment. Despite this, the current structure and content of undergraduate nursing education often contributes to novice RNs feeling unprepared to manage complex pediatric communication situations.

Method:

By merging the characteristics of the Harlequin persona with the structure of story-based learning, undergraduate students can be introduced to increasingly advanced pediatric communication scenarios in the classroom. Although story-based learning encourages students to identify and address the contextual and emotional elements of a story, the Harlequin encourages educators to challenge assumptions and upset the status quo.

Results:

Nursing students can develop advanced communication abilities and learn to identify and cope with the emotions and complexities inherent in pediatric practice and communication.

Conclusion:

Harlequin-inspired story-based learning can enable nurse educators to create interesting, realistic, and challenging pediatric nursing stories designed to push students outside their comfort zones and enhance their advanced pediatric communication abilities. [

Measurement Matters: Improving Measurement Practices in Nursing Education Research
Authors: Spurlock Darrell R.
Published: May 2017

Measurement is a fundamental but often overlooked component of research design and scientific inquiry. In quantitative study designs, the data that are collected, the statistical analyses conducted, and the conclusions drawn from those analyses all hinge on the validity, reliability, and appropriateness of measurements taken during the investigation. Missteps in the measurement process can undermine the validity of a study's findings and in doing so, efforts to advance the science of nursing education will fall short. This month's Methodology Corner article highlights several important measurement-related considerations for nursing education researchers seeking to build the evidence base—the body of knowledge about nursing education—on which instructional, curricular, policy, and planning decisions are made.

Final but, theticality and subjectification
Authors: Hancil Sylvie
Published: May 2017

La particule finale but a été l’objet d’une attention particulière dans de récentes études en anglais américain et en anglais austalien. À présent, il paraît pertinent d’examiner d’autres dialectes de l’anglais. Le but de cet article est d’offrir une étude synchronique de la particule finale but en anglais britannique, pour ses variantes du sud et du nord, à travers l’examen de la partie synchronique orale du British National Corpus et la partie orale du Scottish Corpus of Texts and Speech. En s’appuyant sur les cinq critères qui définissent la catégorie des thétiques, nous montrons que la particule finale but peut être classée comme un thétique avec une structure schématique. L’analyse se focalise aussi sur la façon dont est subjectivisée la particule finale but dans les deux régions.
Academic Performance of Texas Public Schools and Its Relationship with Students' Physical Fitness and Socioeconomic Status
Authors: Jin He , Lu Yongmei
Published: May 2017

This study investigated the relationship between public schools' academic performance in Texas and their students' physical fitness and socioeconomic status (SES) at school-district level. Spearman rank correlations showed that the correlation between body mass index fitness (BMI HFZ) and academic performance was stronger than cardiovascular fitness (CV HFZ). SES was strongly associated with academic performance. Three-way ANOVA analyses revealed significant main effects of gender, SES, and BMI HFZ on Reading tests passing rate while only SES was significant for Math tests passing rate. Higher BMI fitness was associated with higher level of academic performance for school girls than boys except for those in low SES level. Geographically Weighted Regression (GWR) analyses identified important and spatially varied relationships between physical fitness variables, SES, and academic performance across Texas, suggesting the need for regional and locally-targeted policies to address place-specific critical factors for improving schools' academic performance.
