The proof of Birman’s conjecture on singular braid monoids
2003
Let B_n be the Artin braid group on n strings with standard generators sigma_1, ..., sigma_{n-1}, and let SB_n be the singular braid monoid with generators sigma_1^{+-1}, ..., sigma_{n-1}^{+-1}, tau_1, ..., tau_{n-1}. The desingularization map is the multiplicative homomorphism eta: SB_n --> Z[B_n] defined by eta(sigma_i^{+-1}) =_i^{+-1} and eta(tau_i) = sigma_i - sigma_i^{-1}, for 1 <= i <= n-1. The purpose of the present paper is to prove Birman's conjecture, namely, that the desingularization map eta is injective.
Sourcing on the internet: Examining the relations among different phases of online inquiry
2021
This study examined students’ engagement in sourcing throughout online inquiry, that is, when they specified the information need, formulated search queries, evaluated online texts, and composed a written product. Participants were 167 upper secondary school students. Students completed an online inquiry task in a restricted online environment that utilized authentic online texts. Students’ prior topic knowledge and reading fluency was measured and controlled for in the analysis. The results showed that students engaged in sourcing even in the earliest phases of online inquiry. A sequential regression analysis indicated that the more frequently students engaged in sourcing in specifying the…
Structure of locally convex quasi C * -algebras
2008
There are examples of C*-algebras A that accept a locally convex *-topology τ coarser than the given one, such that Ã[τ] (the completion of A with respect to τ) is a GB*-algebra. The multiplication of A[τ] may be or not be jointly continuous. In the second case, Ã[*] may fail being a locally convex *-algebra, but it is a partial *-algebra. In both cases the structure and the representation theory of Ã[τ] are investigated. If Ã+ τ denotes the τ-closure of the positive cone A+ of the given C*-algebra A, then the property Ā+ τ ∩ (-Ā+ τ) = {0} is decisive for the existence of certain faithful *-representations of the corresponding *-algebra Ã[τ]
Are Intercultural Competences at the Center of Job-Market Demands ?
2020
International audience; This chapter introduces the theoretical framework upon which this study was based before going on to set out the methodology used and detail the main results found. It discusses results in the light of scientific literature on the issue and their managerial implications. With the internationalization of organizational structures, the development of intercultural competences was often considered a strategic benefit. Indeed, companies are sensitive to the cultural diversity of their worldwide branches and to the international competences developed by their employees. Through organizational internationalization, intercultural competences become strategic resources. Alth…

Toward adjustment profiles for lower secondary student-athletes in the Finnish dual career context: A mixed-methods approach
2022
Engagement, burnout, and experiences are central concepts for understanding student-athlete adjustment in a dual career (DC) environment. As part of a larger 3-year, lower secondary sports schools pilot project, the aim of this study was to examine student-athletes’ DC adjustment in Finnish lower secondary sports schools at the end of the second academic year. By combining quantitative and qualitative methods, we sought to (a) identify adjustment profiles among student-athletes based on measures of engagement and burnout in school and sport and (b) to extract experiences that describe the distribution of student-athletes in the profiles. A latent profile analysis using questionnaire data fr…
Accuracy of the finite difference method in stochastic setting.
2006
In this paper we study the accuracy of the finite difference method when the finite difference method is applied to approximately analyze the structure.

La música tiene la capacidad de transmitir conocimientos, habilidades y valores intrínsecos a la cultura del compositor, y al mismo tiempo transmite emociones y sentimientos comunes a todas las culturas; por ello puede decirse que la música es un instrumento idóneo para el establecimiento de un diálogo intercultural. La acción comunicativa musical siempre ha sido objeto de análisis; aunque ha sido la falta de diálogo cultural la que ha aumentado la consideración de que la música puede posibilitar el camino hacia la adquisición de la Interculturalidad. Este artículo muestra cómo la música favorece el proceso comunicativo intercultural, al considerarse como la principal herramienta de trabajo…
Die Herausbildung von Zufriedenheits-urteilen bei Alternativenbetrachtung
1999
Traditional elements of competitive differentiation are declining. As industries and firms worldwide face increasing competition, slower growth rates, and price pressures, greater attention is being placed on customer satisfaction. However the research in satisfaction never consider alternatives, when customer satisfaction is formed. It has been the approach of this paper to present an extension for this circumstance. Therefor the regret theory, a diversion of the expectation utility theory, is used to explain the phenomena. According to this theory, each outcome has associated with it the evaluation of the difference between the outcome and the outcome that would have been received had a d…
OHP-041 Formulary Decision-Making For Biosimilars: Considerations For Hospital Pharmacists
2013
Background It has been 6 years since the first biosimilar was approved for use in the European Union (EU). Given the likelihood that biosimilar monoclonal antibodies will be approved in Europe in the near future, it is timely to review the formulary selection criteria for biologicals and biosimilars. The European Medicines Agency (EMA) has issued guidelines that define the regulation of biosimilars in Europe and recommend approaches to establish biosimilarity. However, several questions regarding the assessment of biosimilars for formulary inclusion remain unanswered, including those related to manufacturing and drug supply. Purpose To aid hospital pharmacists in developing evaluation crite…
