Improving the security of multiple passwords through a greater understanding of the human memory
2016
Multiple passwords are an increasing security issue that will only get worse with time. One of the major factors that compromise multiple passwords is users’ memory, and the behaviors they adopt to compensate for its failures. Through studying memory elements that influence users’ password memorability, we may increase our understanding of the user and therefore make proposals to increase the security of the password authentication mechanism. This dissertation examines the human memory to understand password security behaviors; and moreover, develops new theories and revises prominent memory theories for the password context. This research employs memory theories to not only increase the me…
The (micro) processes of integration as dialectic of structure and agency : the case of seconded national experts within the European Commission
2008
Masteroppgave i offentlig politikk og ledelse - Universitetet i Agder 2008 Micro-processes of integration – i.e. how agents develop identities, properties and decision-making behaviours preferred by a particular institution – have been a topic of significant scholarly debate. Most previous work builds on one underlying theoretical framework and thereby excludes (potentially important) elements lying outside it. My thesis attempts to contribute to the ongoing debate by developing a more holistic understanding of these processes, based on the dialectics of structure and agency and thereby positions actors’ decision-making behaviour on a continuum between ‘structural idiocy’ and ‘structural en…
Cosmological origin of anomalous radio background
2012
The ARCADE 2 collaboration has reported a significant excess in the isotropic radio background, whose homogeneity cannot be reconciled with clustered sources. This suggests a cosmological origin prior to structure formation. We investigate several potential mechanisms and show that injection of relativistic electrons through late decays of a metastable particle can give rise to the observed excess radio spectrum through synchrotron emission. However, constraints from the cosmic microwave background (CMB) anisotropy, on injection of charged particles and on the primordial magnetic field, present a challenge. The simplest scenario is with a greater than or similar to 9 GeV particle decaying i…
Exploring the Link between ICT and Development in the Context of Developing Countries : A Literature Review
2014
Published version of an article in the journal: Electronic Journal of Information Systems in Developing Countries. Also available from the publisher at: http://www.ejisdc.org/ojs2/index.php/ejisdc/article/view/1332. Open Access The article contributes to the ongoing discussion on relating information and communication technology (ICT) to development (D). The quest to relate ICT to D is a topic of open deliberation and critical scrutiny in ICT4D research communities. To enhance the understanding in this regard, we conducted a literature review. The review examines 80 articles to identify various development theories and the role of technologies in the development process. While scanning the …

Generalized Virasoro anomaly and stress tensor for dilaton coupled theories
2003
We derive the anomalous transformation law of the quantum stress tensor for a 2D massless scalar field coupled to an external dilaton. This provides a generalization of the Virasoro anomaly which turns out to be consistent with the trace anomaly. We apply it together with the equivalence principle to compute the expectation values of the covariant quantum stress tensor on a curved background. Finally we briefly illustrate how to evaluate vacuum polarization and Hawking radiation effects from these results.
Design e narrazioni
2022
Il testo nasce dall’esigenza di mettere a fuoco le implicazioni cognitive, metodologiche e progettuali del concetto di narrazione, sempre più ricorrente nella nostra esperienza quotidiana soprattutto per le molteplici forme di comunicazione e di produzioni culturali che vi si ispirano; si tratta di un concetto che anche nella riflessione teorica e nella progettualità del design sta alimentando dimensioni fortemente innovative ed evolutive nella costruzione, comunicazione di significati, contenuti immateriali, esperienze e valori emozionali che si sovrappongono e s’intrecciano all’espressione tangibile e funzionale degli oggetti, degli artefatti comunicativi, degli spazi. Si propone un perco…
The Mathematicians’ Happy Hunting Ground: Einstein’s General Theory of Relativity
2004
There is hardly any doubt that for physics special relativity theory is of much greater consequence than the general theory. The reverse situation prevails with respect to mathematics: there special relativity theory had comparatively little, general relativity theory very considerable, influence, above all upon the development of a general scheme for differential geometry. —Hermann Weyl, “Relativity as a Stimulus to Mathematical Research,” pp. 536–537.

Chinese theories of rights are illustrated and critically assessed against traditional legal thinking and Marxist contemporary orthodox legal ideology.
What Human Rights are not (Or not Only). A Negative Path to Human Rights Practice
2014
What human rights are not (or not only) could offer an inclusive and intersectional approach able to get together the different dimensions (moral, legal, social ones) of the international and domestic practice of protecting individuals against violations and discriminations. The book aims at offering an overview of the current phase of the protection of rights, its relationships with and differences from natural rights and liberal rights of the Western tradition, an approach to their content and their possible uses in the domestic and international domain.
