Legitimacy Lost and Back to Normality: Scandals in the Public Sector – the Swedish Case

2007

Scandals provide an opportunity to generate more knowledge about the process in which organizational legitimacy can be restored. This article is based on a study of all scandals in the Swedish public sector from 1995-1997 and four case studies in four organizations conducted 2003. In scandals in the Swedish public sector, players in leading positions are linked to some transgression, often of a financial nature. The less expected the transgression, the stronger the public reaction and the more the organisation’s legitimacy diminish. A scandal implies a failure for everyone in the organisation. The organisation is subjected to questions, scrutiny and slander. Because the tough scrutiny, it b…

Characterization of strong chain geometries by their automorphism group

1992

A wide class of chain geometries is characterized by their automorphism group using properties of a distinguished involution.

Intron variants of the p53 gene are associated with increased risk for ovarian cancer but not in carriers of BRCA1 or BRCA2 germline mutations

1999

Two biallelic polymorphisms in introns 3 and 6 of the p53 gene were analysed for a possible risk-modifying effect for ovarian cancer. Germline DNA was genotyped from 310 German Caucasian ovarian cancer patients and 364 healthy controls. We also typed 124 affected and 276 unaffected female carriers with known deleterious BRCA1 or BRCA2 germline mutation from high-risk breast-ovarian cancer families. Genotyping was based on PCR and high-resolution gel electrophoresis. German ovarian cancer patients who carried the rare allele of the MspI restriction fragment length polymorphism (RELP) in intron 6 were found to have an overall 1.93-fold increased risk (95% confidence internal (CI) 1.27–2.91) w…

The action of a compact Lie group on nilpotent Lie algebras of type {{n,2}}

2015

Abstract We classify finite-dimensional real nilpotent Lie algebras with 2-dimensional central commutator ideals admitting a Lie group of automorphisms isomorphic to SO 2 ⁢ ( ℝ ) ${{\mathrm{SO}}_{2}(\mathbb{R})}$ . This is the first step to extend the class of nilpotent Lie algebras 𝔥 ${{\mathfrak{h}}}$ of type { n , 2 } ${\{n,2\}}$ to solvable Lie algebras in which 𝔥 ${{\mathfrak{h}}}$ has codimension one.

Hypothalamic-Pituitary-Adrenal axis and cognitive function in healthy older people: genetic, situational and individual factors

2019

The world population is getting older, and this age group faces important health challenges, among which age-related cognitive decline stands out. Therefore, it is important to identify vulnerability and protective health factors in order to understand ways to prevent cognitive decline. This thesis aimed to address the relationship between the Hypothalamic–Pituitary–Adrenal (HPA) axis and cognitive functioning during aging, taking into account genetic (Apolipoprotein E, ApoE, polymorphism), situational (loneliness), and individual factors (personality traits). To do this, a group of healthy older people over 55 years of age, men and women, were evaluated. A neuropsychological battery was ad…

Embeddings of Danielewski hypersurfaces

2008

In this thesis, we study a class of hypersurfaces in $\mathbb{C}^3$, called \emph{Danielewski hypersurfaces}. This means hypersurfaces $X_{Q,n}$ defined by an equation of the form $x^ny=Q(x,z)$ with $n\in\mathbb{N}_{\geq1}$ and $\deg_z(Q(x,z))\geq2$. We give their complete classification, up to isomorphism, and up to equivalence via an automorphism of $\mathbb{C}^3$. In order to do that, we introduce the notion of standard form and show that every Danielewski hypersurface is isomorphic (by an algorithmic procedure) to a Danielewski hypersurface in standard form. This terminology is relevant since every isomorphism between two standard forms can be extended to an automorphism of the ambiant …

The Abelian Kernel of an Inverse Semigroup

2020

The problem of computing the abelian kernel of a finite semigroup was first solved by Delgado describing an algorithm that decides whether a given element of a finite semigroup S belongs to the abelian kernel. Steinberg extended the result for any variety of abelian groups with decidable membership. In this paper, we used a completely different approach to complete these results by giving an exact description of the abelian kernel of an inverse semigroup. An abelian group that gives this abelian kernel was also constructed.
