Geometric Summary of the 9 Chip Ladder for the D0 Silicon Tracker

Two hybrids types are required to accomodate the flipping of ladders within each bulkhead layer, in order to account for the pigtail routing. Left and right versions are shown below, following the definitions laid out by Mike Matulik. These drawings are not to proper scale in the sketches below. The dimensionally correct versions of the 9 chip hybrids are stored in DCS under drawing number 3823.112-MD-317803 for the lefthanded version, and 3823.112-MD-317804 for the right handed version. Handedness of the hybrids are designated as shown in the figures and table below. There are long and short versions of both the left and the right, for four total 9 chip hdi designs. The pigtail lengths of the long and short are shown in a table in the hybrid drawings which reside in DCS. The chamfer in the hybrid corners (N side) is placed in order to enable the hybrid to be glued to the beryllium substrate, whereas the rectangular cuttout on the same side is to allow direct gluing of a temperature sensor to the substrate metal. The oblong shape on the N side of both hybrids is a 'stay-clear' region (defined in the final drawings) where pressure will be applied to the hybrid during the second stage of ladder construction

No association between islet cell antibodies and coxsackie B, mumps, rubella and cytomegalovirus antibodies in non-diabetic individuals aged 7–19 years

Viral antibodies were tested in a cohort of 44 isletcell antibody-positive individuals age 7–19 years, and 44 of their islet cell antibody-negative age and sex-matched classmates selected from a population study of 4208 pupils who had been screened for islet cell antibodies. Anti-coxsackie B1-5 IgM responses were detected in 14 of 44 (32%) of the islet cell antibody-positive subjects and in 7 of 44 (16%) control subjects. This difference did not reach the level of statistical significance. None of the islet cell antibody-positive subjects had specific IgM antibodies to mumps, rubella, or cytomegalovirus. There was also no increase in the prevalence or the mean titres of anti-mumps-IgG or IgA and anti-cytomegalovirus-IgG in islet cell antibody-positive subjects compared to control subjects. These results do not suggest any association between islet cell antibodies, and possibly insulitis, with recent mumps, rubella or cytomegalo virus infection. Further studies are required to clarify the relationship between islet cell antibodies and coxsackie B virus infections

Capturing heterogeneity and PLS-SEM prediction ability: Alliance governance and innovation

Whether the uses of PLS-SEM latent interaction effect (PLS-LIE), PLS prediction-oriented segmentation (PLS-POS), or PLS-PATHMOX approaches improve prediction ability remains unclear. The present study draws on holdout sample estimations to assess prediction ability for the three approaches. The illustrative empirical model focuses on examining the differences in innovation outcomes that coopetive alliances produce, in which three governance factors may affect the structural model parameter estimates reflecting these differences. The findings suggest improvements in prediction ability with the use of PLS-LIE and PLS-POS but not for PLS-PATHMOX

Student evaluation of problem-based learning in a dental orthodontic curriculum - A Pilot study

Objective: The present questionnaire survey investigated student reception of problem-based learning (PBL) in the orthodontic curriculum with regard to acceptance, sense of purpose and motivation, knowledge and understanding, as well as tutorial support.Methods: Over a period of two terms, we compared two different didactic methods (PBL and short presentations) by randomizing the participants of a course on orthodontic diagnostics into two different groups, who inversed methods after the first term. Results: The two student groups did not show any significant differences with regard to assessments or examination performance. Therefore, acceptance of the PBL concept seems to be mainly associated with the motivation of individuals to use this method. The higher the motivation, the more positive is the attitude towards the PBL concept. Students seem to work more constructively and efficiently with PBL if they can judge the concept meaningful for themselves.Conclusion: In consideration of the relevant literature and the present results, PBL can be principally integrated into the dental curriculum as a method of learning. However, student motivation is vital to learning success.Ziel: In der vorliegenden Fragebogenstudie wurde die studentische Rezeption des problemorientierten Lernens (POL) im Curriculum der Kieferorthopädie hinsichtlich Akzeptanz, Sinn/Motivation, Wissen/Verstehen und tutorieller Unterstützung) untersucht. Methode: Es erfolgte eine Gegenüberstellung zweier verschiedener didaktischer Methoden (POL, Kurzreferate) bei der Durchführung des kieferorthopädischen Diagnostikkurses in einem randomisierten Zwei-Gruppen-Plan über zwei Semester, in dem die Reihenfolge der Methoden variiert wurde. Ergebnisse: Es konnten keine Unterschiede zwischen den Gruppen bezüglich ihrer Einschätzungen und Prüfungsleistungen gefunden werden. Es zeigt sich, dass die Akzeptanz des POL hauptsächlich mit der individuellen Motivation zum POL zusammenhängt. Je höher die Motivation, desto positiver die Einstellung. Die Studierenden können mit der Methode effektiver und konstruktiver arbeiten, wenn sie selbst motiviert sind bzw. für sich einen Sinn in POL erkennen. Schlussfolgerung: Unter Berücksichtigung des Literaturstudiums und der vorliegenden Ergebnisse ist das POL grundsätzlich als Lehrmethode in die zahnmedizinische Ausbildung integrierbar. Die Motivation der Studierenden stellt einen entscheidenden Faktor für den Lernerfolg dar

Core business prospects and the management of internal corporate ventures

Abstract: Corporations with attractive core business prospects focus their attention on those core businesses and away from ICVs they may be pursuing, thus influencing how those ICVs are treated from a corporate parenting perspective and, in turn, how well they perform. Using data collected from 145 ICVs operating in 72 corporate parents, this research reveals that corporations with more attractive core businesses grant greater planning autonomy to their ICVs’ managers, and planning autonomy contributes to ICV performance. Additional results reveal the moderating effects within our structural model of venture manager experience and the similarity of the ICV’s product to those of other businesses within the corporation. Considered collectively, this research demonstrates why corporations that “need” their ICVs to be successful – because of poor prospects in their core businesses – are most likely to mismanage them. Unattractive core business prospects can be viewed as justifying corporate managers’ involvement in the direct management of their firms’ ICVs. However, venture planning autonomy is needed to avoid placing undue expectations on ICVs as the “saviors” of corporate performance. By extension, this need for autonomy is also anticipated to apply to other entrepreneurial contexts where experimentation and learning are significant concerns (e.g., business incubators, corporate venture capital investments, new venture divisions). Plain English Summary: This research demonstrates how and why corporations that have attractive core business operations are most likely to be good corporate parents to their internal corporate ventures (ICVs), and vice versa. In a sense, when it comes to internal corporate venturing, “the rich corporations get richer, and the poor corporations get poorer.” Parent corporations with more attractive core business prospects were found to grant greater planning autonomy to the managers of their ICVs, and autonomy is needed to give ICV managers the discretion and flexibility they need when navigating their ventures though unchartered business territory. Overall, this research demonstrates the importance of corporate managers (1) granting ICV managers autonomy in planning their venture operations, (2) being willing to consider engaging in internal corporate venturing even though their firms’ existing, core business operations may be attractive (i.e., before these ICVs “need” to be successful), and (3) not putting too much pressure on ICVs to “perform,” and avoiding meddling in the management of those ventures, when prospects in the corporation’s core business are unattractive. We argue that autonomy is likely efficacious in most entrepreneurial contexts where experimentation and learning are significant concerns (e.g., business incubators, corporate venture capital investments, new venture divisions)

Vegetation productivity in drylands from MERIS FAPAR time series

This paper provides an overview of the European Space Agency (ESA) DUE Project Diversity II, specifically the dryland component of this dual project with a dryland and an inland water part. The 10 years of MERIS data have been exploited using full and reduced resolution fAPAR data to profile and trace the vegetation development in 22 dryland sites all over the globe. Objectives were to map and assess status and trends of vegetation productivity and express the results in a suite of indicators. The work was driven by the information needs of the CBD (Convention on Biological Diversity) and the UNCCD (UN Convention to Combat Desertification)
