description: We propose an efficient optical electromagnetically induced transparency (EIT) cooling scheme for a cantilever with a nitrogen-vacancy center attached in a non-uniform magnetic field using dynamical Zeeman effect. In our scheme, the Zeeman effect combined with the quantum interference effect enhances the desired cooling transition and suppresses the undesired heating transitions. As a result, the cantilever can be cooled down to nearly the vibrational ground state under realistic experimental conditions within a short time. This efficient optical EIT cooling scheme can be reduced to the typical EIT cooling scheme under special conditions.

description: The thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) is widely applied in the biomedical field particularly as thermoresponsive substrate for culture of cells. To be used as a stimuli-responsive coating for cell culture, combining PNIPAM with glycosaminoglycans might be an effective approach to improve its bioactivity. In this study, chitosan is grafted with PNIPAM moieties (PCHI) possessing a cloud point at 31 ​°C and used as a polycation to fabricate thermoresponsive polyelectrolyte multilayers (PEM) with the bioactive polyanion chondroitin sulfate (CS) at pH 4 by layer-by-layer technique. The in-situ investigation by surface plasmon resonance and quartz crystal microbalance with dissipation monitoring confirms that the formation of PEMs with CS can be achieved despite the bulky structure of PCHI at 25 ​°C. The stability of the PEMs is further improved at physiological pH 7.4 by chemical crosslinking using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide. Moreover, these PEMs exhibit de-swelling and swelling ability with different surface wettability in response to temperature, which triggers the adsorption and desorption of adhesive protein vitronectin on the PEMs. At 37 ​°C, the PEMs containing PNIPAM particularly associated with CS terminal layer supports protein adsorption and consequently enhances cell adhesion using multipotent murine stem cells. Overall, due to improved stability, crosslinked PNIPAM-modified biogenic multilayers are cytocompatible and hold great potential as culture substrate for different tissue cells and application in tissue engineering.

description: Mit den nachfolgend beschriebenen Ergebnissen einer Ausgrabung in Zentral-Libyen wird ein Siedlungsplatz vorgestellt, dessen epipaläolithisches Fundmaterial sowohl typologisch als auch absolutchronologisch in die zweite Hälfte des 8. Jahrtausends v. Chr. eingeordnet werden konnte. Eine Korrespondenzanalyse des Werkzeuginventars bekräftigt eine hohe Übereinstimmung mit zeitgleichen Fundplätzen der Westlichen Wüste Ägyptens. Damit liegen erstmals gesicherte Belege für die Wiederbesiedlung der hyperariden Ostsahara im frühen Holozän innerhalb einer rund 1.000 km weiten Fundlücke zwischen der Großen Sandsee Ägyptens und dem westlichen Libyen vor.
description: During a recent excavation at a settlement site in central Libya Epipalaeolithic material was uncovered. Typological analysis as well as three radiocarbon dates allow to chronologically position the assemblage to the 2nd half of the 8th mill. BC. A Correspondence Analysis of the toolkit corroborates the strong similarities with contemporaneous sites in the Western Desert of Egypt. This provides the first reliable evidence of the reoccupation of the formerly hyper-arid Eastern Sahara during the Early Holocene within an approx. 1.000 km wide and archaeologically unexplored area between the Great Sand Sea of Egypt and western Libya.

description: Viroids are small, single-stranded, non-protein coding and circular RNAs able to infect host plants in the absence of any helper virus. They may elicit symptoms in their hosts, but the underlying molecular pathways are only partially known. Here we address the role of post-transcriptional RNA silencing in plant-viroid-interplay, with major emphasis on the involvement of this sequence-specific RNA degradation mechanism in both plant antiviroid defence and viroid pathogenesis. This review is a tribute to the memory of Dr. Ricardo Flores, who largely contributed to elucidate this and other molecular mechanisms involved in plant-viroid interactions.

description: Hintergrund: Auch die ambulante Chirurgie trägt zur Klimakrise bei. Die Publikation soll die Herausforderungen identifizieren und klare, möglichst evidenzbasierte Empfehlungen für Umweltschutz bei gleichzeitiger Kostenreduktion geben. Methode: Narratives Review mit nichtsystematischer umfangreicher Recherche in PubMed/MEDLINE und grauer Literatur sowie Befragung von Expert:innen. Ergebnisse: Eine Vielzahl an Primärarbeiten, Evidenzsynthesen, praktischen Handlungsempfehlungen und Checklisten konnte identifiziert und zwei Expert:innen befragt werden. Umweltprobleme wurden erkannt in Produktion und Beschaffung, Verkehr, beim Verbrauch von Material, Pharmaka und Energie sowie bei Entsorgung, Wiederverwertung und Sterilisation. Hochwertige Publikationen beschreiben nicht einen Mangel an Wissen um Alternativen, sondern an praktischer Umsetzung. Deshalb wurden die Probleme in das 5‑R-Schema („reduce“, „reuse“, „recycle“, „rethink“, „research“) eingeordnet, um Handlungsempfehlungen mit Synergieeffekten bezüglich Kostenreduktion, Patient:innen- und Mitarbeiter:innenzufriedenheit zu präsentieren. Des Weiteren werden Veränderungen der Rahmenbedingungen diskutiert. Schlussfolgerung: Ambulantes Operieren geht mit relevantem Ressourcenverbrauch einher. Es existieren zahlreiche Möglichkeiten, Umweltschutz mit Kostenreduktion sowie Zufriedenheit von Patient:innen und Mitarbeiter:innen zu verbinden. Für flächendeckenden Klimaschutz in der Niederlassung müssen Anreize und gesetzliche Rahmenbedingungen geschaffen werden.

title: 'Imperfect adumbrations' : boys, men, and masculinities in the work of Virginia Woolf
Creators: name: Griffin, Lisa Myfanwy
Publisher: name: University of St Andrews
Year: 2015

description: This thesis will suggest how Woolf scholarship’s rich exploration of Virginia Woolf’s representations of girls, women and femininities may be complemented by more systematic feminist study of constructs of masculinities, as they appear in her work. Elaborating the concept of the ‘private brother’, the figure of a form of maleness that the daughters of educated men ‘have reason to respect’, but that Three Guineas’ narrator stipulates is ‘sunk’ by men’s exposure to society and replaced by the ‘monstrous male’, my thesis will focus particularly on the representations of boys, men and masculinities in To the Lighthouse, Between the Acts and Woolf’s biography Roger Fry, though I will additionally use material from Woolf’s essays, diaries and letters, as well as from Mrs Dalloway, The Years and The Pargiters. The first section of my thesis will supplement feminist critiques of the education received by upper-middle-class English boys in Woolf’s texts by exploring her representations of young male (inter)subjectivities in the process of being ‘sunk.’ In the second section, I will complicate the narrative trajectories often indicated for these characters in Woolf criticism by proposing that Woolf understood this sinking process as always incomplete: I will argue that Woolf’s adult male characters, even her patriarchs, professors and otherwise educated men, vacillate continually between stances that might be characterised as monstrous maleness and private brotherliness–in both ‘public’ and intimate settings–as one of the preconditions of social existence.

description: Recent CLAS data for the pi Sigma invariant mass distributions (line-shapes) in the gamma p -> K^+ pi Sigma reaction are theoretically investigated. The line-shapes have peaks associated with the Lambda(1405) excitation. Our model consists of gauge invariant photo-production mechanisms, and the chiral unitary model that gives the rescattering amplitudes where Lambda(1405) is contained. It is found that, while the pi Sigma line-shape data in the Lambda(1405) region are successfully reproduced by our model for all the charge states, the production mechanism is not so simple that we need to introduce parameters associated with short-range dynamics to fit the data. Our detailed analysis suggests that the nonresonant background contribution is not negligible, and its sizable effect shifts the Lambda(1405) peak position by several MeV. We also analyze the data using a Breit-Wigner amplitudes instead of those from the chiral unitary model. We find that the fitted Breit-Wigner parameters are closer to the higher pole position for Lambda(1405) of the chiral unitary model. This work sets a starting point for a fuller analysis in which line-shape as well as K^+ angular distribution data are simultaneously analyzed for extracting Lambda(1405) pole(s).

description: We establish direct connections at several levels between quantum groups and supergroups associated to bar-consistent super Cartan datum by constructing an automorphism (called twistor) in the setting of covering quantum groups. The canonical bases of the halves of quantum groups and supergroups are shown to match under the twistor up to powers of a square root of -1. We further show that the modified quantum group and supergroup are isomorphic over the rational function field adjoint with a square root of -1, by constructing a twistor on the modified covering quantum group. An equivalence of categories of weight modules for quantum groups and supergroups follows.

description: Background and objectives: Disease progression in patients with spinal muscular atrophy (SMA) has changed dramatically within the past years due to the approval of three different disease-modifying treatments. Nusinersen was the first drug to be approved for the treatment of SMA patients. Clinical trials provided data from infants with SMA type 1 and children with SMA type 2, but there is still insufficient evidence and only scarcely reported long-term experience for nusinersen treatment in ambulant patients. Here, we report data from the SMArtCARE registry of ambulant patients under nusinersen treatment with a follow-up period of up to 38 months. Methods: SMArtCARE is a disease-specific registry in Germany, Austria and Switzerland. Data are collected as real-world data during routine patient visits. Our analysis included all patients under treatment with nusinersen able to walk independently before start of treatment with focus on changes in motor function. Results: Data from 231 ambulant patients were included in the analysis. During the observation period, 31 pediatric walkers (27.2%) and 31 adult walkers (26.5%) experienced a clinically meaningful improvement of≥30 m in the 6-Minute-Walk-Test. In contrast, only five adult walkers (7.7%) showed a decline in walking distance≥30 m, and two pediatric walkers (1.8%) lost the ability to walk unassisted under treatment with nusinersen. HFMSE and RULM scores improved in pediatric and remained stable in adult patients. Conclusion: Our data demonstrate a positive effect of nusinersen treatment in most ambulant pediatric and adult SMA patients. We not only observed a stabilization of disease progression or lack of deterioration, but clinically meaningful improvements in walking distance.

description: Natural antisense long non-coding RNAs (lncNATs) are involved in the regulation of gene expression in plants, modulating different relevant developmental processes and responses to various stimuli. We have identified and characterized two lncNATs (NAT1UGT73C6 and NAT2UGT73C6, collectively NATsUGT73C6) from Arabidopsis thaliana that are transcribed from a gene fully overlapping UGT73C6, a member of the UGT73C subfamily of genes encoding UDP-glycosyltransferases (UGTs). Expression of both NATsUGT73C6 is developmentally controlled and occurs independently of the transcription of UGT73C6 in cis. Downregulation of NATsUGT73C6 levels through artificial microRNAs results in a reduction of the rosette area, while constitutive overexpression of NAT1UGT73C6 or NAT2UGT73C6 leads to the opposite phenotype, an increase in rosette size. This activity of NATsUGT73C6 relies on its RNA sequence and, although modulation of UGT73C6 in cis cannot be excluded, the observed phenotypes are not a consequence of the regulation of UGT73C6 in trans. The NATsUGT73C6 levels were shown to affect cell proliferation and thus individual leaf size. Consistent with this concept, our data suggest that the NATsUGT73C6 influence the expression levels of key transcription factors involved in regulating leaf growth by modulating cell proliferation. These findings thus reveal an additional regulatory layer on the process of leaf growth. In this work, we characterized at the molecular level two long non-coding RNAs (NATsUGT73C6) that are transcribed in the opposite direction to UGT73C6, a gene encoding a glucosyltransferase involved in brassinosteroid homeostasis in A. thaliana. Our results indicate that NATsUGT73C6 expression influences leaf growth by acting in trans and by modulating the levels of transcription factors that are involved in the regulation of cell proliferation.

description: Overall, previous research seems to point to higher emotional intelligence (EI) in the gifted students (see meta-analyses by Abdulla Alabassi et al., 2020; Ogurlu, 2021). Proposals understand the importance of incorporating the study of EI in giftedness (Zeidner & Matthews, 2017), even suggesting that higher EI can serve as an identifying criterion for giftedness (Abdulla et al., 2020). However, it is still common for adults to perceive social problems or show particular concern for the social-emotional development of the gifted individual, consistent with the stereotype of the "mad genius" among the general population (Baudson, 2016). The present protocol proposes a meta-analysis that has a threefold objective. Firstly, it aims to test whether gifted students show significant differences in their EI compared to non-gifted students. Secondly, to determine whether there are differences in EI between twice-exceptional students and non-gifted students. Finally, it aims to address which of the aforementioned characteristics may be acting as moderators of those differences. From a theoretical point of view, the results will shed light on the discussion between ability, trait, and mixed-concept models of EI, as well as their classification according to performance or self-perception. Also, the results will help to shed light on an existing need on the identification and classification of giftedness, which needs to be more precise since it does not consist of a single profile.

description: Effective degradation (ED) of crude protein (CP) was estimated in vitro at 0.02, 0.05 and 0.08 h−1 assumed ruminal passage rates for a total of 40 feedstuffs, for which in situ ED was available and used as reference degradation values. For this, the Streptomyces griseus protease test was used. The differences between in vitro CP degradation and the in situ CP degradation values were lowest in legume grains and highest in cereal by-products and barley. The differences between in situ and in vitro ED were expressed using a degradation quotient (degQ), where degQ = (EDin vitro − EDin situ)/EDin situ. Among the tested feedstuffs, eight specific clusters were identified according to degQ for the assumed passage rates. The feedstuffs clustered in an unspecific way, i.e., feedstuffs of different nutrient composition, origin or treatment did not necessarily group together. Formaldehyde–treated rapeseed meal, soybean meal, wheat, a treated lupin, sunflower meal and barley could not be assigned to any of the clusters. Groupwise degradation (range of degQ for assumed passage rates are given in brackets) was detected in grass silages (−0.17, −0.11), cereal by-products together with sugar beet pulp (−0.47, −0.35) and partly in legume grains (−0.14, 0.14). The clustering probably based on different specific nutrient composition and matrix effects that influence the solubility of feed protein and limit the performance of the protease. The matrix can be affected by treatment (chemically, thermally or mechanically), changing the chemical and physical structure of the protein within the plant. The S. griseus protease test had reliable sensitivity to reflect differences between native feedstuffs and treatments (thermally or chemically) that were found in situ. The in situ results, however, are mostly underestimated. The clustering results do not allow a clear conclusion on the groupwise or feed-specific use of carbohydrate-degrading enzymes as pre- or co-inoculants as part of the S. griseus protease test and need to be tested for its potential to make this test more conform with in situ data.
Just for whom? Including immigrant and migrant workers of Asian descent in the energy transition dialogue in Alberta, Canada
Creators: Kim Marriott, Ella
Publisher: name: University of Alberta Library
Year: 2023

There is agreement amongst activists, politicians, the majority of the public and even industry stakeholders that shifting away from carbon-intensive industries is necessary to get on a path towards mitigating climate change. There is also widespread support for a transition that prioritizes the rights of those who will be vulnerable to these shifts, including resource-dependent and Indigenous communities, workers, and other marginalized groups. However, there is still much debate over what this transition will look like. This research imagines an energy transition that reflects the concerns, values and priorities of Asian immigrant and migrant oil and gas workers. In the introduction, I put forward a brief summary of the concepts of energy justice and energy democracy and how they guided this research project, as well as contextualize the experiences of Asian immigrants as diasporic subjects in Canada in relation to their unique histories of outmigration and discrimination. Based on fifteen semi-structured interviews with immigrant and migrant workers of Asian descent with experience working in both white-collar and blue-collar professions in the oil and gas industry in Alberta, I take two approaches to analyzing the interview data that bring about important insights for the energy transition literature. Firstly, I propose that an intersectional lens applied to dimensions of the matrix of domination such as race, class, gender and age can illustrate the unique, yet interrelated values, priorities and concerns of Asian immigrants and migrants. Secondly, I suggest that looking at underlying systems of oppression, namely white hegemony that uses race-based justifications for valuing some bodies over others, can shed light on worker complicity and point towards opportunities for building solidarity amongst racialized workers and groups in so-called Canada.

description: If $G$ is a Lie group, $H\subset G$ is a closed subgroup, and $τ$ is a unitary representation of $H$, then the authors give a sufficient condition on $ξ\in i\mathfrak{g}^*$ to be in the wave front set of $\operatorname{Ind}_H^Gτ$. In the special case where $τ$ is the trivial representation, this result was conjectured by Howe. If $G$ is a real, reductive algebraic group and $π$ is a unitary representation of $G$ that is weakly contained in the regular representation, then the authors give a geometric description of $\operatorname{WF}(π)$ in terms of the direct integral decomposition of $π$ into irreducibles. Special cases of this result were previously obtained by Kashiwara-Vergne, Howe, and Rossmann. The authors give applications to harmonic analysis problems and branching problems.

Icing dynamics in the lake-dominated, discontinuous permafrost Taiga Shield, and effects on fluvial biogeochemistry, carbon cycling and microbial communities
Creators: Alsafi, Nora
Publisher: name: University of Alberta Library
Year: 2023

Climate warming is affecting freshwater systems across the western Canadian subarctic, due to widespread shifts in precipitation regimes, permafrost degradation, and multi-decadal increases in winter baseflow. These changes are significant on the Taiga Shield, which comprises ~20% of North America’s permafrost-covered area, encompassing an area of over 1.3 million km^2. This region is characterized by “fill and spill” hydrology, where runoff is generated by the exceedance of lake basin storage thresholds across the landscape. In response to increasing winter baseflow, hydrologic connectivity between the lakes which dominate this region is also increasing. In addition, taliks, zones of unfrozen ground within or above the permafrost layer, are expanding in spatial extent and occurrence across the Taiga Shield. These changes are expected to alter the export of novel chemical constituents, including dissolved organic matter (DOM), to fluvial networks, with potential implications for carbon cycling and the structure of microbial communities, which comprise the base of aquatic food webs. Despite this, the impact of warming on wintertime fluvial biogeochemistry on the Taiga Shield is poorly understood.

In this thesis, I use icings, which are sheet-like masses of layered ice which form when subsurface flow is pushed to the ground surface, as a tool to understand wintertime chemistry. Working in the Yellowknife, NT, region, I developed and tested a conceptual model to consider how hydrological processes and source water characteristics affect icing chemistry. I additionally coupled icing samples to surface water samples from winter, spring, and summer to explore seasonal and icing-driven variation in water chemistry, microbial community structure, and carbon processing rates. I found that icing chemistry was driven by physico-chemical processes, notably anoxia, solute exclusion and sediment-water interaction occurring within icing source waters and along flow paths to sites of icing formation. Icing formation and morphology were driven by temperature and antecedent precipitation levels, which worked together to control wintertime fill and spill hydrology. Icing formation also modified wintertime flow via solute exclusion; icing chemistry was unique, and dominated by DOM that was characteristically aliphatic, protein-like, and was preferentially mineralized to CO2 during an incubation. Seasonal differences in DOM composition also supported unique microbial communities. Overall, these results suggest that winter flow is dynamic, and icings have the potential to modify the composition of water actively flowing through fluvial networks in the winter, and as they thaw in the spring and summer; thus, changes in icing dynamics due to warming may have significant effects on wintertime chemistry and carbon cycling in this region.

description: This article investigates the acquisition of psych verbs in diachrony by applying Yang’s (2016) Tolerance and Suﬀiciency principles. It has been observed that psych verbs change from expressing the EXPERIENCER as object to expressing it as subject cross-linguistically. According to van Gelderen (2018) and others, this development has also taken place in the history of English. What is much less well-known, however, is that a considerable number of Old French psych verbs were copied to Middle English. Using lexicon-based and corpus-based data, we will apply Yang’s (2016) Tolerance and Suﬀiciency Principles to evaluate historical “tipping points” in the de- velopment of the psych verb class, i.e. examine whether either amuse-type or admire-type argument structures were productive in Middle English. Since subject-EXPERIENCERS were commonly used with intransitive and reflexive con- structions we will further investigate whether a more general rule that any psych verb may take a subject-EXPERIENCER passed the productivity threshold. We will show that this was indeed the case in Middle English and that the copying of Old French verbs accelerated this development.

As a side product, we obtain simple symplectic integrators for general Hamiltonian systems on the sphere $S^{2}$.

In our proposed method, we repeat a response measurement against external forces, where the forces are determined by the previous measurement as feedback. Consequently, we obtain a set of stationary states corresponding to an exponential family of distributions, each of which shows rare events in the original system as the typical behavior. As a demonstration of our method, we study large deviation statistics of one-dimensional lattice gas models.

We examined the role of the IP in the domain of second language (L2) acquisition by testing its relations with a robust predictor of L2 use, willingness to communicate (WTC). We collected self-reports of 400 adult Iranian L2 learners and tested the associations between the IP and WTC. As expected, we found a negative association between IP and WTC (r = −0.13). When testing a mediation model with perceived competence and communication anxiety as parallel mediators, we found evidence for full mediation via perceived competence. Our findings show the importance of considering self-evaluations in the domain of L2 acquisition. Further implications and limitations are discussed.

description: We infer mechanisms of galaxy formation for a broad family of semi-analytic models (SAMs) constrained by the K-band luminosity function and HI mass function of local galaxies using tools of Bayesian analysis. Even with a broad search in parameter space the whole model family fails to match to constraining data. In the best fitting models, the star formation and feedback parameters in low-mass haloes are tightly constrained by the two data sets, and the analysis reveals several generic failures of models that similarly apply to other existing SAMs. First, based on the assumption that baryon accretion follows the dark matter accretion, large mass-loading factors are required for haloes with circular velocities lower than 200 km/s, and most of the wind mass must be expelled from the haloes. Second, assuming that the feedback is powered by Type-II supernovae with a Chabrier IMF, the outflow requires more than 25% of the available SN kinetic energy. Finally, the posterior predictive distributions for the star formation history are dramatically inconsistent with observations for masses similar to or smaller than the Milky-Way mass. The inferences suggest that the current model family is still missing some key physical processes that regulate the gas accretion and star formation in galaxies with masses below that of the Milky Way.

description: Background: Neurological soft signs (NSS) are often reported in patients with schizophrenia and may vary with psychopathological symptoms during the course of disease. Many cross-sectional neuroimaging studies have shown that NSS are associated with disturbed network connectivity in schizophrenia. However, it remains unclear how these associations change over time during the course of disorder. Methods: In present study, 20 patients with first-episode schizophrenia and 20 controls underwent baseline structural magnetic resonance imaging (MRI) scan and at one-year follow-up. Structural network characteristics of patients and controls were analyzed using graph theoretical approach based on MRI data. NSS were assessed using the Heidelberg scale. Results: At baseline, patients demonstrated significant changes of the local network properties mainly involving regions of the cortical-subcortical-cerebellar circuits compared to healthy controls. For further analysis, the whole patient group was dichotomized into a NSS-persisting and NSS-decreasing subgroup. After one-year follow-up, the NSS-persisting subgroup showed decreased betweenness in right inferior opercular frontal cortex, left superior medial frontal cortex, left superior temporal cortex, right putamen and cerebellum vermis and increased betweenness in right lingual cortex. However, the NSS-decreasing subgroup exhibited only localized changes in right middle temporal cortex, right insula and right fusiform with decreased betweenness, and in left lingual cortex with increased betweenness. Conclusions: These findings provide evidence for brain network reorganization subsequent to clinical disease manifestation in patients with first-episode schizophrenia, and support the hypothesis that persisting NSS refer to progressive brain network abnormalities in patients with schizophrenia. Therefore, NSS could help to establish a better prognosis in first-episode schizophrenia patients.

description: The possibility of quantum computation using non-Abelian anyons has been considered for over a decade. However the question of how to obtain and process information about what errors have occurred in order to negate their effects has not yet been considered. This is in stark contrast with quantum computation proposals for Abelian anyons, for which decoding algorithms have been tailor-made for many topological error-correcting codes and error models. Here we address this issue by considering the properties of non-Abelian error correction in general. We also choose a specific anyon model and error model to probe the problem in more detail. The anyon model is the charge submodel of $D(S_3)$. This shares many properties with important models such as the Fibonacci anyons, making our method applicable in general. The error model is a straightforward generalization of those used in the case of Abelian anyons for initial benchmarking of error correction methods. It is found that error correction is possible under a threshold value of $7 \%$ for the total probability of an error on each physical spin. This is remarkably comparable with the thresholds for Abelian models.
Mentorship for New Faculty Members: A Qualitative Follow-up to Prior Canadian Research
Creators: Allan, Katherine A

Faculty members play a critical role in upholding the academic mission of institutions of higher

education and are integral in supporting student success. It is widely understood that new faculty

struggle and as incoming cohorts of new faculty become increasingly diverse, their unique

challenges are beginning to be studied. This requires that new faculty receive appropriate support

as they transition into academia. Mentorship, originally examined through the traditional dyad

model has long been seen as the solution that benefits the mentee, the mentor and the institution:

the benefit triad. That said, recent research has begun to question the benefit triad and alternative

mentorship models are being studied. The gap in the Canadian higher education literature,

particularly of cross discipline mentorship initiatives and their long-term implications, led to this

study. Thus, the purpose of this study is to build upon prior research to contribute to a qualitative

retrospective exploration of mentorship. This qualitative study interviewed 46 faculty members

(new faculty and chairs of departments) to gauge their reactions to prior research findings and

explore their perspectives to see what if anything has shifted over time regarding mentorship

practices. Overwhelmingly participants were not surprised by the summary of previous findings,

suggesting that not much has changed. The implications of this research, as viewed through the

conceptual framework of this study ethics of care/caring democracy, are that faculty members

need to be cared with via mentorship and other initiatives throughout their transition especially

amidst the rising pressures of the neoliberal institution.

description: Cet article présente une revue de la littérature sur l'utilisation de la vidéo dans l'analyse de l'activité (Poizat & Durand, 2015), afin de concevoir une approche méthodologique qui permet d’analyser l'activité réelle des chefs d’établissement au Maroc. Les résultats de notre recherche montrent que dans le cadre de l'analyse de l'activité, la vidéo est utilisée comme support aux : verbalisations du travailleur pour pouvoir expliquer chaque geste, au codage des gestes ou de la direction du regard, ainsi qu'à l'observation d'autres données sur le poste de travail (Yvon & Saussez, 2010). Nos résultats montrent également qu’il existe de multiples options méthodologiques sur le choix des types d'enregistrements vidéo et leurs modes d'exploitation : · Vidéo de l’acteur analysée par un intervenant : Entretien en rappel stimulé (Tochon, 1996). · Vidéo de l’acteur analysée par un acteur (lui-même) : Entretien d’auto-confrontation simple (Theureau, 2010). · Vidéo de l’acteur analysée par le collectif d’acteurs : Entretien en auto-confrontation croisée (Clot, et al., 2000). · Vidéo de l’acteur analyse conjointe de l’intervenant et des acteurs : Enquête collaborative (Mollo, Falzon, 2004). La force de cette approche réside dans l'implication des travailleurs dans la sélection des scénarios qui, selon eux, favoriseront le mieux leur développement professionnel et celui de leurs pairs, ainsi que dans leur participation à la prise de décisions sur la conception du dispositif de formation qui est basé sur l’analyse de l’activité (Asloum et al., 2022).

description: In a homogeneous and isotropic universe bulk viscosity is the unique viscous effect capable to modify the background dynamics. Effects like shear viscosity or heat conduction can only change the evolution of the perturbations. The existence of a bulk viscous pressure in a fluid, which in order to obey to the second law of thermodynamics is negative, reduces its effective pressure. We discuss in this study the degeneracy in bulk viscous cosmologies and address the possibility that phantom dark energy cosmology could be caused by the existence of non-equilibrium pressure in any cosmic component. We establish the conditions under which either matter or radiation viscous cosmologies can be mapped into the phantom dark energy scenario with constraints from multiple observational data-sets

description: Aim: This European multicentric study aimed to prove safety and performance of the Bonebridge BCI 602 in children and adults suffering from either conductive hearing loss (CHL), mixed hearing loss (MHL), or single-sided sensorineural deafness (SSD). Methods: 33 patients (13 adults and 10 children with either CHL or MHL and 10 patients with SSD) in three study groups were included. Patients were their own controls (single-subject repeated measures), comparing the unaided or pre-operative to the 3-month post-operative outcomes. Performance was evaluated by sound field thresholds (SF), word recognition scores (WRS) and/or speech reception thresholds in quiet (SRT) and in noise (SNR). Safety was demonstrated with a device-specific surgical questionnaire, adverse event reporting and stable pure-tone measurements. Results: The Bonebridge BCI 602 significantly improved SF thresholds (+ 25.5 dB CHL/MHL/SSD), speech intelligibility in WRS (+ 68.0% CHL/MHL) and SRT in quiet (− 16.5 dB C/MHL) and in noise (− 3.51 dB SNR SSD). Air conduction (AC) and bone conduction (BC) thresholds remained stable over time. All adverse events were resolved, with none unanticipated. Mean audio processor wearing times in hours [h] per day for the CHL/MHL group were ~ 13 h for adults, ~ 11 h for paediatrics and ~ 6 h for the SSD group. The average surgical length was 57 min for the CHL/MHL group and 42 min for the SSD group. The versatility of the BCI 602 (reduced drilling depth and ability to bend the transition for optimal placement) allows for treatment of normal, pre-operated and malformed anatomies. All audiological endpoints were reached. Conclusions: The Bonebridge BCI 602 significantly improved hearing thresholds and speech understanding. Since implant placement follows the patient’s anatomy instead of the shape of the device and the duration of surgery is shorter than with its predecessor, implantation is easier with the BCI 602. Performance and safety were proven for adults and children as well as for the CHL/MHL and SSD indications 3 months post-operatively.
