On the Convergence of Ritz Values, Ritz Vectors, and Refined Ritz Vectors
No full textThis paper concerns the Rayleigh--Ritz method for computing an approximation to an eigenpair (; x) of a non-Hermitian matrix A. Given a subspace W that contains an approximation to x, this method returns an approximation (; ~ x) to (; x). We establish four convergence results that hold as the deviation ffl of x from W approaches zero. First, the Ritz value converges to . Second, if the residual A~x \Gamma ~x approaches zero, then the Ritz vector ~ x converges to x. Third, we give a condition on the eigenvalues of the Rayleigh quotient from which the Ritz pair is computed that insures convergence of the Ritz vector. Finally, we show that certain refined Ritz vectors, introduced by the first author, converge unconditionally.

Einstein’s Investigations of Galilean Covariant Electrodynamics prior to 1905
No full textEinstein learned from the magnet and conductor thought experiments how to use field transformation laws to extend the covariance to Maxwell’s electrodynamics. If he persisted in his use of this device, he would have found that the theory cleaves into two Galilean covariant parts, each with different field transformation laws. The tension between the two parts reflects a failure not mentioned by Einstein: that the relativity of motion manifested by observables in the magnet and conductor thought experiment does not extend to all observables in electrodynamics. An examination of Ritz’s work shows that Einstein’s early view could not have coincided with Ritz’s on an emission theory of light, but only with that of a conveniently reconstructed Ritz. One Ritz-like emission theory, attributed by Pauli to Ritz, proves to be a natural extension of the Galilean covariant part of Maxwell’s theory that happens also to accommodate the magnet and conductor thought experiment. Einstein's famous chasing a light beam thought experiment fails as an objection to an ether-based, electrodynamical theory of light. However it would allow Einstein to formulate his general objections to all emission theories of light in a very sharp form. Einstein found two well known experimental results of 18th and19th century optics compelling (Fizeau’s experiment, stellar aberration), while the accomplished Michelson-Morley experiment played no memorable role. I suggest they owe their importance to their providing a direct experimental grounding for Lorentz’ local time, the precursor of Einstein’s relativity of simultaneity, and do it essentially independently of electrodynamical theory. I attribute Einstein’s success to his determination to implement a principle of relativity in electrodynamics, but I urge that we not invest this stubbornness with any mystical prescience
Homeoffice im öffentlichen Sektor: PublicPanel.ch - Umfragereport
No full textZur Unterstützung der empirischen Forschung in den Bereichen Verwaltungs-, Politik- und Rechtswissenschaft hat das Kompetenzzentrum für Public Management (KPM) der Universität Bern 2021 das PublicPanel, ein Umfragepanel für den schweizerischen öffentlichen Sektor lanciert. Das Panel hat zum Ziel, aktuelle Fragestellungen zur Verwaltung in der Schweiz zeitnah und auf der Basis realer Verwaltungsakteure erforschen zu können. Zeitgleich mit der Lancierung des Panels wurde eine erste Umfrage zum Thema «Homeoffice im öffentlichen Sektor» durchgeführt. Die Rückmeldungen gewähren einen Einblick in die Erfahrungen, welche Beschäftigte im öffentlichen Sektor 2020/2021 mit der vom Bundesrat verhängten Homeofficepflicht gemacht haben. Von den befragten Personen haben rund die Hälfte ihre Arbeitszeit mehrheitlich im Homeoffice verbracht. Pandemiebedingt hat die Umstellung auf Homeoffice für viele sehr rasch und ohne grosse Vorbereitungszeit erfolgen müssen. Dennoch waren die befragten Personen mehrheitlich zufrieden mit der ihnen zur Verfügung stehenden Infrastruktur und der Kommunikation mit Team und Vorgesetzten

Should the Employee Promise of Ritz Carlton Gold Standards be updated?
No full textTutor: Jorge PeraltaThe Ritz Carlton Company is a worldwide leader in the hospitality industry that has been successful
more than one hundred years thanks to their strong philosophy, based on their Gold Standards that
includes: The Motto, The Credo, The Service Values and the most important for this thesis, The
Employee Promise. Without any doubt the success of this luxury brand comes from the employee
satisfaction and performance as a major determinant of the corporate culture of the property.But
should the Employee Promise of the Gold Standards be updated in order adapted their values and
beliefs to the current employees?
This paper explains the origins of the Ritz Carlton and beginnings of its philosophy, also talks about
the internal Marketing in 21st century hotel employee professional profile, defines the Company
Gold Standards, compares employee satisfaction with customer satisfaction and emphasize the
importance of employee engagement.
The researchers have supported their findings with a summary of the existing literature that covers
the mission, vision and values of The Ritz Carlton Company and connect their Golds Standards as a
guide tool to train their employees with guest satisfaction. Also, interviewed employees with
differents positions from line staff to managers that work or have been working in the company by
using questions related with the corporate values and faiths of the company, which clear
determinate the relationship between the employee satisfaction and the performance appraisal.
Gold standards still appear as strong philosophy nowadays for those employees that are recruited by
the company, minor changes seemed to be needed although the evolution of employees

A simple and accurate mixed Ritz-DQM formulation for free vibration of rectangular plates involving free corners
No full textAbstractIt is well known that the classical global approximation methods such as the conventional Ritz method and the conventional differential quadrature method (DQM) have some difficulty in determining the natural frequencies of rectangular plates involving free corners. The mixed Ritz-DQM formulation, which has been recently developed by the present author, was also shown to have such difficulty. This is because it is very difficult to implement the free corner boundary condition in these methods. To overcome this difficulty, this paper presents a mixed Ritz-DQM formulation in which the free corner boundary condition is implemented in a simple and easy manner. First, we present a new scheme for implementing multiple boundary conditions in the DQM discretized equations. By the help of this scheme, we then show that the free corner boundary condition can also be easily implemented in the final matrix equations of the Ritz-DQM approach. Finally, we validate the effectiveness of the proposed approach through numerical experiments. Numerical results show the advantages of the proposed method over some versions of the DQM in terms of accuracy and performance
