The minimal free resolution of fat almost complete intersections in ℙ1 x ℙ1
2017
AbstractA current research theme is to compare symbolic powers of an ideal I with the regular powers of I. In this paper, we focus on the case where I = IX is an ideal deûning an almost complete intersection (ACI) set of points X in ℙ1 × ℙ1. In particular, we describe a minimal free bigraded resolution of a non-arithmetically Cohen-Macaulay (also non-homogeneous) set 𝒵 of fat points whose support is an ACI, generalizing an earlier result of Cooper et al. for homogeneous sets of triple points. We call 𝒵 a fat ACI.We also show that its symbolic and ordinary powers are equal, i.e, .

Negotiating the symbolic power of information and communication technologies (ICT): The spread of Internet-supported distance education
2009
Submitted version of an article in the journal: Information Technology for Development The deposited fulltext is a preprint of the definitive article at Wiley Interscience http://dx.doi.org/10.1002/itdj.20110 The Internet may be, as typically suggested, important in distance education for facilitating connections between groups of students, educational institutions, and external learning resources. This article, however, reveals why this is not the only reason for applying information and communication technologies (ICT) in higher education in a remote area in a developing country. In addition, the Internet seems to be of great importance in symbolizing modernization and progress, thereby a…
Steiner systems and configurations of points
2020
AbstractThe aim of this paper is to make a connection between design theory and algebraic geometry/commutative algebra. In particular, given any Steiner SystemS(t, n, v) we associate two ideals, in a suitable polynomial ring, defining a Steiner configuration of points and its Complement. We focus on the latter, studying its homological invariants, such as Hilbert Function and Betti numbers. We also study symbolic and regular powers associated to the ideal defining a Complement of a Steiner configuration of points, finding its Waldschmidt constant, regularity, bounds on its resurgence and asymptotic resurgence. We also compute the parameters of linear codes associated to any Steiner configur…
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
Racial Stratification of Traditional Medicine’s Consumption in South Africa
2018
Introduction: Post-apartheid South Africa remains highly stratified on variable grounds including race. The 8.9 percent (whites) of the total population has an average income per capita that is five times higher than that of 79.2 percent (blacks). Socio-economic inequalities are embedded in a ‘culture of consumption’ which includes the availability of goods for sale and the marketization of basic human life experiences including health. Study Objective: The objective of this review was to ascertain the racial status quo in traditional medicines consumption. Results: Literature shows that the consumption of traditional medicines is saturated within the Black population at 72 percent whilst d…
The global ranking game : narrowing academic excellence through numerical objectification
2018
The objective of this article is to study some of the intended and unintended effects on academe of the evolving global ranking game. I will start with some broader points on the global ranking game, the formal terms and economic interests it promotes, then continue with a presentation of the Shanghai ranking and its main rival the Times Higher Education. Through reversed engineering, I will bring out the main problems of the Shanghai ranking. I will finish with some of the key features of the demand side, the uses and effects of the tool: the psychosocial mechanisms that reproduce ranking and the lock-ins it creates. peerReviewed
