Marc Jacobs Unseen
No full textMarc Jacobs Unseen is ‘the first publication dedicated to Marc Jacobs’s highly influential creations’*, described by The Observer as ‘a rare insight’ and Vogue as ‘a real revelation’. The particular focus of this critical appraisal is the personal archive (a recurring feature in Webb’s practice), notably those of the subject (Marc Jacobs), the photographer (Robert Fairer), and the author (Webb). The genesis of the text for this sole-authored book that accompanies new primary material in the form of Fairer’s previously unseen backstage images, is research from Webb’s own archive, amassed over four decades during his career at the forefront of the fashion industry, and represents a culmination of the author’s commitment to the promotion of the importance of the archive as material culture, as methodology and as providing an individual insight into creative thinking. The text takes the form of painstakingly assembled commentaries, each presenting a study of specific collections, highlighting particular garments and ensembles along with an analysis of environment and staging. ‘Working with Iain R. Webb…was illuminating,’ says Fairer. Jacobs Unseen is a valuable and illuminating analysis for both colleagues and students, especially those working in areas of fashion design, journalism and visual communication
The Evolving Role of the External Search Firm in the Canadian Decanal Search
No full textDespite the critical role academic deans play in the leadership and success of universities, most of what we know about the Canadian deanship we know from an institutional perspective, including our understanding of the recruitment and selec-tion process. The findings presented in this article will facilitate a better understanding of how the increased involvement of external search firms in decanal searches has influenced both the decanal search process and the experiences of those candidates involved in the search. Provosts, deans, and search firm representatives participated in this study. The resultant findings have several important implications for search policy and process, and the conceptual framework proposed will support new research in the area of senior administrative hiring within Canadian universities.Malgré le rôle essentiel que jouent les doyens d’université dans le leadership et la réussite des universités, la plupart de nos connaissances sur le décanat au Canada sont issues d’une perspective institutionnelle, y compris notre compréhension du processus de recrutement et de sélection. Les résultats présentés dans cet article permettront de mieux comprendre comment la participation accrue des agences de recrutement externes a influencé à la fois le processus de recrutement et l’expérience des candidats. Des vice-recteurs, des doyens et des représentants d’agences de recrutement ont participé à cette étude. Les résultats ont plusieurs implications importantes pour la politique et le processus de recherche, et le cadre conceptuel proposé soutiendra de nouvelles recherches dans le domaine de l’embauche de cadres supérieurs dans les universités canadiennes

No full textProfessor Alan Bromberg was the foremost authority in the law of Rule 10b-5. In this article, the author Professor Marc Steinberg, Professor Bromberg\u27s colleague for 25 years, highlights Professor Bromberg\u27s scholarship in this area. Focusing on key U.S. Supreme Court decisions and congressional legislation, Professor Steinberg reflects on the dialogue that he had with Professor Bromberg through the years on these developments. As this article illustrates, Professor Bromberg enjoyed a truly impressive academic career
LET THE DEANS SPEAK: DECANAL PERCEPTIONS OF INSTITUTIONAL RECRUITMENT PRACTICES
No full textIn spite of the critical role academic deans play in universities (Del Favero, 2006; Dunning, Durham, Aksu, & Lange, 2007; Jackson, 2004), most of what we know about the Canadian deanship we know from an institutional perspective, including our understanding of the recruitment and selection process (Lavigne, 2018). This study explores how successful decanal candidates experience their recruitment processes, how these experiences inform their decision making within that process, and how the process can be improved to support the success of a new dean. Multiperspectival Interpretative Phenomenological Analysis was used to gather data about the recruitment process from a variety of directly related groups. Provosts, deans, and search firm representatives participated in this study. Each study participant had been involved in a recent decanal recruitment and selection process in one form or another. Eight of the 13 participants were sitting deans.
Participants all agreed that the search firm is central to the experience of candidates in a decanal search. Provosts, search firm representatives, and candidates alike confirmed that one of the firm’s most important roles, in addition to their support of the search committee in the first stages of position profile and job description development, is initial outreach to candidates. Provosts also highlighted the important role of the search committee, although deans and search firm representatives did not always agree. Search politics, and their influence on the conduct and experience of a search were highlighted in various forms by all participants. The pivotal role of the provost was also noted.
By expanding upon Harvey et al.’s (2013) Reference Point Theory it became possible to further our understanding of how search firm representatives and other actors influence a decanal candidate’s decision making within a search. The resultant findings have several important implications for policy, practice, and theory. Given the importance candidates place on search firm representatives and the influence they have on the decisions candidates make within the search process, it is important for institutions to consider alignment between the philosophy of a firm and that of the hiring college, faculty, or wider institution. Institutions and provosts in particular also need to be sure that search firms have access to all of the details, pleasant or otherwise, about both the hiring college or faculty and the decanal position itself. A well-informed search firm representative can more accurately explain the position to candidates as they move through the search. A well-informed candidate can make better-informed decisions as part of that search. In future, including the perspectives of individuals beyond Western Canadian institutions would provide further insights into the decanal recruitment process on a national scale
Verified Trust: Reciprocity, Altruism, and Noise in Trust Games
No full textBehavioral economists have come to recognize that reciprocity, the interaction of trust and trustworthiness, is a distinct and economically relevant component of individual preferences alongside selfishness and altruism. This recognition is principally due to observed decisions in experimental "trust games". However, recent research has cast doubt on the explanatory power of trust as a determinant of those decisions, suggesting that altruism may explain much of what "looks like" trust. Moreover, empirical tests for alternative behavioral determinants can be sensitive to experimental bias due to differences in protocols and framing. Therefore, we propose discriminatory tests for altruism and trust that can be based on within-treatment and within-subject comparisons, and we control for group attributes of experimental subjects. Our results support trust (i.e. expected reciprocation) as the dominant motivation for "trust like" decisions.reciprocity; altruism; trust game; experimental error
The discovery of SycO reveals a new function for type three secretion effector chaperones
No full textThe Type Three Secretion (T3S) system is a device used by many Gram-negative pathogens that allows bacteria to deliver effector proteins straight into the eukaryotic cell cytosol. These effectors interfere with various signaling pathways to subvert the host cell functions. The secretion machinery of the T3S system consist of a basal body spanning the bacterial inner and outer membrane followed by a stiff hollow needle outside the bacterium. The fully assembled secretion apparatus constitute a continuous hollow conduit that connects the bacteria to the eukaryotic target cell. After cell contact, virulence proteins -called effectors- are injected directly into the cytosol of the host cell via the T3S apparatus. Several effectors of the T3S system require the assistance of specific cytosolic chaperones to be efficiently exported. There are three classes of T3S chaperones. Effector proteins are assisted by Class I chaperones. Although Class I chaperones are well characterized, their main function is still a matter of controversy. In this thesis, we demonstrate that orf155 encodes a specific chaperone for the effector YopO that we called SycO. We showed that SycO enhances YopO secretion in vitro and is required for translocation of YopO into infected cells. By pulldown assay we demonstrated that residues 20 to 77 of YopO are required and sufficient for SycO binding. Using crosslinking experiments and size exclusion chromatography analysis, we determined the stoichiometry of purified SycO and YopO-SycO complexes. SycO alone forms dimers in solution and the YopO-SycO complex has a 1:2 stoichiometry. These results suggested that SycO is a typical chaperone of the Class I. YopO is a serine/theronine kinase that interacts with Rho and Rac and disrupts the cytoskeleton of the target cells. YopO has been shown to localize at the cell plasma-membrane. By transfection of YopO-EGFP hybrid proteins into HEK293T cells, we demonstrated that the chaperone-binding domain (CBD) coincides with the membrane localization domain of YopO. Nevertheless, the CBD was not needed for the kinase activity of YopO. By ultracentrifugation, we also showed that the CBD causes YopO aggregation in the bacteria, when SycO does not cover it. Further, we show that the CBD of YopE and YopT also caused aggregation in the bacteria in the absence of SycE and SycT respectively. YopE, YopT and T3S effectors in other systems also act at the membrane of the eukaryotic host cell. We propose a new hypothesis concerning the role of T3S chaperones. The sub-cellular localization domain of effectors is aggregation-prone and creates the need for a chaperone inside bacteria. We propose that masking such aggregation-prone localization domains may be a general function for type III effector chaperones
Equilibrium transition study for a hybrid MAV
No full textWind tunnel testing was performed on a VTOL aircraft in order to characterize longitudinal flight behavior during an equilibrium transition between vertical and horizontal flight modes. Trim values for airspeed, pitch, motor speed and elevator position were determined. Data was collected by independently varying the trim parameters, and stability and control derivatives were identified as functions of the trim pitch angle. A linear fractional representation model was then proposed, along with several methods to improve longitudinal control of the aircraft
An investigation into Grade R teachers' experiences of implementing numeracy in Grade R
No full textThis research study investigates how selected Grade R teachers implement numeracy in their classrooms, based on their experiences, personal beliefs and perceptions. This study adopts the view that a teacher's practice is not only informed on what she believes about her learners, but also on how she organises her classroom environment and her own teaching practice. However, the teacher cannot be divorced from the political and historical
background of Early Childhood Development (ECD), as these factors have an impact on her numeracy implementation. Integrated in this research study is thus not only a comprehensive historical analysis of the historical and political background of ECD, but also an in-depth look at the complex curriculum road the Grade R teacher had to travel over the past twelve years. The aim of this case study is to understand and describe what is happening in Grade R classrooms when numeracy is implemented, as well as identifying possible barriers which Grade R teachers may experience in implementing numeracy. The author utilized an adapted Interactive Qualitative Analysis Framework to explore Grade R teachers' views and experiences. Open-ended focus group interviews were used to develop a framework for individual interviews. This interview framework guided the data collection of nine audio-video tapes of classroom activities and nine semi-structured individual interviews. Analysis of the individual interviews revealed each teacher's understanding as well as her perceptions and needs regarding the implementation of numeracy in her classroom. The transcriptions of the individual interviews were compared to the audio-video tapes of what happened in each classroom. This was done in order to determine whether the teachers' practices were consistent with what they said in the interviews. Paradoxes and inconsistencies were documented. The historical and political analysis of ECD illustrates the complex development of ECD in
South Africa over the last few decades. It therefore also highlights and brings to the fore the complex journey that Grade R teachers had to navigate in adapting their practice to ever changing curriculum requirements. The empirical results show that there are inconsistencies between what selected teachers know and believe, and what they are implementing. However, "silent themes" which did not come to the fore in the focus group or individual interviews, were identified in the audiovideo tapes of classroom activities. Also, many "silent themes" indicate that there are numerous concerns, such as lack of proficiency in bridging the gap between theory and practice, regarding the implementation of numeracy in Grade R. It was found that many of the selected Grade R teachers struggle to implement numeracy in their classrooms, as they lack the skills and support to teach numeracy in a Grade R context
