SOV approach for integrable quantum models associated to general representations on spin-1/2 chains of the 8-vertex reflection algebra
2013
The analysis of the transfer matrices associated to the most general representations of the 8-vertex reflection algebra on spin-1/2 chains is here implemented by introducing a quantum separation of variables (SOV) method which generalizes to these integrable quantum models the method first introduced by Sklyanin. More in detail, for the representations reproducing in their homogeneous limits the open XYZ spin-1/2 quantum chains with the most general integrable boundary conditions, we explicitly construct representations of the 8-vertex reflection algebras for which the transfer matrix spectral problem is separated. Then, in these SOV representations we get the complete characterization of t…
Deformation quantization of covariant fields
2002
After sketching recent advances and subtleties in classical relativistically covariant field theories, we give in this short Note some indications as to how the deformation quantization approach can be used to solve or at least give a better understanding of their quantization.
Integrating over quiver variety and BPS/CFT correspondence
2019
We show the vertex operator formalism for the quiver gauge theory partition function and the $qq$-character of highest-weight module on quiver, both associated with the integral over the quiver variety.
Some considerations on adapting academic qualifications to the Romanian labor market
2017
The paper presents the results of some research carried out by the authors during the activities of the “Academic Entrepreneurial Laboratory – Progress through Innovation and Practice – (Univers Practic)” and seeks to evince certain key aspects pertaining to the adaptation of university qualifications to the needs of the Romanian workforce. First, the general context of higher education and the current state of affairs, as reflected by the analysis of relevant works in the field are presented. This is followed by a presentation of the main results of a questionnaire-based study that evinces the opinions of students, graduates, and company managers with regard to the necessity of adapting ac…
IRT Modeling of Decomposed Student Learning Patterns in Higher Education Economics
2019
Researchers have spent decades arguing how to measure improvements in learning within formal settings, where achievements are intended and presupposed, in a reliable and valid way. Repeated measures are required to investigate improvements of any kind. Students usually take a multiple-choice test at least twice with the difference between the two measurements indicating how much they have learned. Walstad and Wagner (J Econ Educ 47:121–131, 2016) presented a new approach to gathering more information about different learning patterns by decomposing these difference measures. They describe the patterns of positive learning (PL) and negative learning (NL), i.e., the development from not knowi…
Development of a conceptual model of sustainable building from a university
2021
Introduction: In this paper, the authors aim is to develop a conceptual model that aims to facilitate the processes of implementing sustainability and / or assessment of sustainable performance in a Higher Education Building (HEB). The conceptual model could also be used to compare two or more buildings of higher education in terms of sustainability. Methodology: The authors started the scientific research with the literature review in order to identify and analyze the most relevant aspects that are frequently assess and could influencing the components of sustainability in higher education institutions. These aspects were clustered into categories and for each of them were established obje…
How are the Concepts and Theories of Acid–Base Reactions Presented? Chemistry in Textbooks and as Presented by Teachers
2005
This paper investigates the views of science and scientific activity that can be found in chemistry textbooks and heard from teachers when acid–base reactions are introduced to grade 12 and university chemistry students. First, the main macroscopic and microscopic conceptual models are developed. Second, we attempt to show how the existence of views of science in textbooks and of chemistry teachers contributes to an impoverished image of chemistry. A varied design has been elaborated to analyse some epistemological deficiencies in teaching acid–base reactions. Textbooks have been analysed and teachers have been interviewed. The results obtained show that the teaching process does not emphas…
Contemporary art in higher education: creative pedagogies in political economy
2019
Abstract We propose that contemporary art, which reflects the problems and attitudes of our times, can be used as a way of promoting creativity in disciplines that are not traditionally associated with the arts. Whilst contemporary art is being used as a learning and teaching aid in higher education in a small number of disciplines, it is not normally used in disciplines dominated by rational discourse; an example is economics, on which we focus. We begin by reviewing the literature on art, education and creativity. We then perform an activity with students taking political economy. Students are given the task of selecting a work of contemporary art which “speaks” to them about political ec…
Las materias de Patrimonio y Museología en el grado de Historia del Arte en universidades españolas
2020
Este artículo analiza la incorporación en el ámbito universitario de los contenidos de Patrimonio y Museología vinculados a la Historia del Arte. A pesar de que son inherentes al nacimiento de la disciplina, su presencia explícita en los planes de estudio es bastante reciente. Con especial protagonismo se incorporaron con la creación de la licenciatura de la Historia del Arte y, después, del grado. En este caso, a partir de su diseño bajo las exigencias del Espacio Europeo de Educación Superior (EEES). Con dicho marco, se compara la actual representación de las asignaturas de Patrimonio y Museología en el grado de Historia del Arte en las universidades españolas, así como su imbricación con…
On the graded identities and cocharacters of the algebra of 3×3 matrices
2004
Abstract Let M2,1(F) be the algebra of 3×3 matrices over an algebraically closed field F of characteristic zero with non-trivial Z 2 -grading. We study the graded identities of this algebra through the representation theory of the hyperoctahedral group Z 2 ∼S n . After splitting the space of multilinear polynomial identities into the sum of irreducibles under the Z 2 ∼S n -action, we determine all the irreducible Z 2 ∼S n -characters appearing in this decomposition with non-zero multiplicity. We then apply this result in order to study the graded cocharacter of the Grassmann envelope of M2,1(F). Finally, using the representation theory of the general linear group, we determine all the grade…
