Developing professionalism in a college of business: The implementation of a professionalism recognition program: Working paper series--11-06

This paper explores the importance of developing professionalism attributes among business students and the implementation of a program designed to incentivize professionalism behaviors during undergraduate study at a college of business. The "Professionalism Recognition Program" (PRP) was established as a co-curricular activity to promote, evaluate, recognize and reward professionalism behaviors of students. We also describe the key aspects of the program's development and implementation, noting the key resources and constituencies involved as well as considerations for the adoption of similar programs elsewhere. It is hoped that the lessons learned during our implementation and communicated in this manuscript will help others to successfully develop and implement their own programs to improve the professionalism behaviors of students

Dilution effects in Ho2−x_{2-x}Yx_xSn2_2O7_7: from the Spin Ice to the single-ion magnet

A study of the modifications of the magnetic properties of Ho$_{2-x}$Y$_x$Sn$_2$O$_7$ upon varying the concentration of diamagnetic Y$^{3+}$ ions is presented. Magnetization and specific heat measurements show that the Spin Ice ground-state is only weakly affected by doping for $x\leq 0.3$, even if non-negligible changes in the crystal field at Ho$^{3+}$ occur. In this low doping range $\mu$SR relaxation measurements evidence a modification in the low-temperature dynamics with respect to the one observed in the pure Spin Ice. For $x\to 2$, or at high temperature, the dynamics involve fluctuations among Ho$^{3+}$ crystal field levels which give rise to a characteristic peak in $^{119}$Sn nuclear spin-lattice relaxation rate. In this doping limit also the changes in Ho$^{3+}$ magnetic moment suggest a variation of the crystal field parameters.Comment: 4 pages, 5 figures, proceedings of HFM2008 Conferenc

Violence à l’encontre du personnel des établissements médico-sociaux et des centres médico-sociaux du Canton de Vaud. Synthèse des résultats

Présenté au Grand Conseil du Canton de Vaud lors de la séance du 30 juin 2015, le postulat « Philippe Vuillemin et consorts – Pour une meilleure protection du personnel soignant en EMS » part du constat que, si la maltraitance des personnes âgées est désormais reconnue et appréhendée par les différents acteurs concernés, celle à l’égard des soignant-e-s et des personnels travaillant en établissements médico-sociaux (EMS) et dans les centres médico-sociaux (CMS) est plus rarement évoquée publiquement. Certain-e-s professionnel-le-s (par exemple : policier-ère-s, enseignant-e-s, personnels des établissements de santé) présentent des risques accrus d’être confrontés à des actes de violence à leur égard. Le travail isolé et le contact avec des clients, en particulier lorsque ces derniers sont sous l’emprise de la drogue ou de l’alcool, quand ils sont connus pour avoir eu un passé violent ou qu’ils souffrent de maladies pouvant être associées à des comportements agressifs constituent ainsi des facteurs de risque. Le risque d’être confronté à la violence ou à des comportements agressifs concerne aussi les professionnel-le-s en contact avec des personnes atteintes dans leur santé, à domicile ou en institution. Des enquêtes menées dans les établissements médico-sociaux (EMS) ou auprès des professionnel-le-s du maintien à domicile, à l’étranger et en Suisse rapportent des taux relativement élevés d’exposition à la violence chez les soignant-e-s. On ne dispose en revanche d’aucune donnée concernant cette problématique pour la Suisse Romande ou pour le Canton de Vaud

A note on entropic force and brane cosmology

Recently Verlinde proposed that gravity is an entropic force caused by information changes when a material body moves away from the holographic screen. In this note we apply this argument to brane cosmology, and show that the cosmological equation can be derived from this holographic scenario.Comment: 5 pages, no figures;references adde

Church-Rosser Systems, Codes with Bounded Synchronization Delay and Local Rees Extensions

What is the common link, if there is any, between Church-Rosser systems, prefix codes with bounded synchronization delay, and local Rees extensions? The first obvious answer is that each of these notions relates to topics of interest for WORDS: Church-Rosser systems are certain rewriting systems over words, codes are given by sets of words which form a basis of a free submonoid in the free monoid of all words (over a given alphabet) and local Rees extensions provide structural insight into regular languages over words. So, it seems to be a legitimate title for an extended abstract presented at the conference WORDS 2017. However, this work is more ambitious, it outlines some less obvious but much more interesting link between these topics. This link is based on a structure theory of finite monoids with varieties of groups and the concept of local divisors playing a prominent role. Parts of this work appeared in a similar form in conference proceedings where proofs and further material can be found.Comment: Extended abstract of an invited talk given at WORDS 201

Tunneling magnetoresistance in diluted magnetic semiconductor tunnel junctions

Using the spin-polarized tunneling model and taking into account the basic physics of ferromagnetic semiconductors, we study the temperature dependence of the tunneling magnetoresistance (TMR) in the diluted magnetic semiconductor (DMS) trilayer heterostructure system (Ga,Mn)As/AlAs/(Ga,Mn)As. The experimentally observed TMR ratio is in reasonable agreement with our result based on the typical material parameters. It is also shown that the TMR ratio has a strong dependence on both the itinerant-carrier density and the magnetic ion density in the DMS electrodes. This can provide a potential way to achieve larger TMR ratio by optimally adjusting the material parameters.Comment: 5 pages (RevTex), 3 figures (eps), submitted to PR

Complexity of Left-Ideal, Suffix-Closed and Suffix-Free Regular Languages

A language $L$ over an alphabet $\Sigma$ is suffix-convex if, for any words $x,y,z\in\Sigma^*$, whenever $z$ and $xyz$ are in $L$, then so is $yz$. Suffix-convex languages include three special cases: left-ideal, suffix-closed, and suffix-free languages. We examine complexity properties of these three special classes of suffix-convex regular languages. In particular, we study the quotient/state complexity of boolean operations, product (concatenation), star, and reversal on these languages, as well as the size of their syntactic semigroups, and the quotient complexity of their atoms.Comment: 20 pages, 11 figures, 1 table. arXiv admin note: text overlap with arXiv:1605.0669

An Adaptive Observer-based Robust Estimator of Multi-sinusoidal Signals

This paper presents an adaptive observer-based robust estimation methodology of the amplitudes, frequencies and phases of biased multi-sinusoidal signals in presence of bounded perturbations on the measurement. The parameters of the sinusoidal components are estimated on-line and the update laws are individually controlled by an excitation-based switching logic enabling the update of a parameter only when the measured signal is sufficiently informative. This way doing, the algorithm is able to tackle the problem of over-parametrization (i.e., when the internal model accounts for a number of sinusoids that is larger than the true spectral content) or temporarily fading sinusoidal components. The stability analysis proves the existence of a tuning parameter set for which the estimator\u2019s dynamics are input-to-state stable with respect to bounded measurement disturbances. The performance of the proposed estimation approach is evaluated and compared with other existing tools by extensive simulation trials and real-time experiments
