Supersymmetry in non commutative superspaces
2003
Non commutative superspaces can be introduced as the Moyal-Weyl quantization of a Poisson bracket for classical superfields. Different deformations are studied corresponding to constant background fields in string theory. Supersymmetric and non supersymmetric deformations can be defined, depending on the differential operators used to define the Poisson bracket. Some examples of deformed, 4 dimensional lagrangians are given. For extended superspace (N>1), some new deformations can be defined, with no analogue in the N=1 case.
Differential algebras in non-commutative geometry
1993
We discuss the differential algebras used in Connes' approach to Yang-Mills theories with spontaneous symmetry breaking. These differential algebras generated by algebras of the form functions $\otimes$ matrix are shown to be skew tensorproducts of differential forms with a specific matrix algebra. For that we derive a general formula for differential algebras based on tensor products of algebras. The result is used to characterize differential algebras which appear in models with one symmetry breaking scale.
Gravity, Non-Commutative Geometry and the Wodzicki Residue
1993
We derive an action for gravity in the framework of non-commutative geometry by using the Wodzicki residue. We prove that for a Dirac operator $D$ on an $n$ dimensional compact Riemannian manifold with $n\geq 4$, $n$ even, the Wodzicki residue Res$(D^{-n+2})$ is the integral of the second coefficient of the heat kernel expansion of $D^{2}$. We use this result to derive a gravity action for commutative geometry which is the usual Einstein Hilbert action and we also apply our results to a non-commutative extension which, is given by the tensor product of the algebra of smooth functions on a manifold and a finite dimensional matrix algebra. In this case we obtain gravity with a cosmological co…
Integrating the Analysis of Mental Operations Into Multilevel Models to Validate an Assessment of Higher Education Students’ Competency in Business a…
2016
The Standards for Educational and Psychological Testing indicate that validation of assessments should include analyses of participants’ response processes. However, such analyses typically are conducted only to supplement quantitative field studies with qualitative data, and seldom are such data connected to quantitative data on student or item performance. This paper presents an example of how data from an analysis of mental operations collected using a sociocognitive approach can be quantitatively integrated with other data on student and item performance to validate in part an assessment of higher education students’ competency in business and economics. Evidence of forward reasoning an…
Academic capitalism and the informational fraction of the transnational capitalist class
2013
This article is based on the idea that if we are witnessing an on-going shift towards the transnational phase of capitalism, this objective structural change should also be taken into account in higher education studies. In this sense, this article reflects the increased scholarly attention into the relationship between globalisation and higher education since the 1990s. The main purpose of this article is to contribute to these discussions by developing dialogue between global capitalism theories and the theory of academic capitalism. In order to achieve this, William Robinson's concept of the transnational capitalist class (TCC) will be amended to include also the informational fraction. …
Student teachers’ ways of experiencing the teaching of health education
2010
The aim of this phenomenographic study was to identify student teachers’ ways of experiencing the teaching of health education, and to determine the aspects that are educationally critical in gaining a deeper understanding of the teaching. Qualitative data (written essays, semi‐structured interviews) were gathered twice during health education teacher training. Teaching was seen as transferring knowledge and skills, supporting the active processing of knowledge, supporting transformation of conceptions, supporting holistic personal growth and building a learning community with the students. The teaching was reflected through five themes: the nature of the knowledge, the source of the knowle…
Intellectual Property and Leverage: The Role of Patent Portfolios
2019
This paper analyses the importance of intellectual property in determining capital structure decisions. We argue that firms can use their patent stock as collateral and thereby relax possible debt financing restrictions. Using data from the European Patent Office and balance sheet data of European companies, we find that larger and more valuable patent stocks lead to higher debt-ratios - controlling for well-established capital structure determinants. We further assess variation across as well as within industries and show that effects are mainly driven by tech-oriented and research intensive firms. Drawing on a legislative change in EU- law, allows us to establish a causal relationship bet…
Aspectos de la revolución jurídica en el decreto de los señoríos de 1811
2001
One of the basic elements which the bourgeoisie needed to address in the process of revolution was the transformation of the landholding regime and the instruments which conditioned the social relations of production: seigneurial, and principally jurisdictional, rights. This meant two tasks: overcoming the juridical structure that underlay the feudal property regime and the creation of a new system that might regulate relationships of capitalist production. Peculiarities and doubts about the origin of the feudal property regime and seigneurial rights, and the relationship between the two, would open up a series of questions relating to their legality and legitimacy, including the right of c…
From Ethnic Law to Town Law: The Customs of the Kingdom of Sicily from the Twelfth to the Fifteenth Century
2016
The history of Sicily, the largest island of the Mediterranean, is notably distinct from the history of the rest of Italy. It is because of this distinctiveness that Sicily can serve as a paradigmatic example of a pluralist legal system, one with a mix of both personal-law and territorial-law rules. In the time period that I examine in this essay, customary law took several different forms. What legislation, private records, and judicial decisions all call »custom« plays three different roles: law of specific ethnic groups, rights and customary practices concerning real property, and the law of towns.
Gendered Life-Course Patterns in Post-Socialist Romania: An Illustration from Households Situated in Precarious Prosperity
2017
AbstractThis paper documents the gendered aspects of changes affecting the life course of Romanians post-socialism, and the meanings men and women—with ages spanning across various age cohorts—employ to make sense of their experiences. Based on qualitative data collected during research on precarious prosperity among Romanian households conducted in 2013, the findings show that major shifts occurred in the timing of life events. Romanians’ life courses and their work trajectories have been unevenly affected depending on their intersectional belonging to gender, area of residence and life stage at the moment of the political transition. The analysis of work trajectories unravels increasing g…
