Trust in electronic banking

Trust among stakeholders is vital for the successful implementation of IS projects such as electronic banking, because such IS initiative do not typically require face-to-face interactions. The Business-to-Business (B2B) model is an example of a relationship that facilitates the implementation of electronic banking. For example, ICT suppliers in alliance with banks to provide and support the IT infrastructure required for electronic banking implementation. These different stakeholders may have different perceptions of trust, which may affect electronic banking implementation. This short paper’s aim is to examine how trust from the stakeholder theory perspective impacts the implementation of electronic banking. This paper proposes, from the stakeholder perspective, an integrated framework that conceptualizes trust between B2B relationships as antecedent to the successful implementation of electronic banking. The research will be based on the multi-case study method. Our proposed study provides a foundation for researchers and practitioners alike in understanding the concept of trust and its impact on IS projects

An Evaluation of Non-Stochastic Lattice Structures Fabricated Via Electron Beam Melting

Metal foam structures have many applications and can be used as structural supports, heat exchangers, shock absorbers, and implant materials. Stochastic metal foams having different cell sizes and densities have been commercially available for a number of years. This paper addresses a different type of foams which are known as non-stochastic foams, or lattice structures. These foams have a well defined repeating unit cell structure rather than the random cell structure in commercially available stochastic foams. The paper reports on preliminary research on the fabrication of non-stochastic Ti-6Al-4V alloy foams using the Electron Beam Melting process. Behavior of the structures in compression, bending, and low cycle repeating load tests are discussed, and recommendations about cell geometry and processing conditions are made.Mechanical Engineerin

Generalised Space-time and Gauge Transformations

We consider the generalised space-time introduced by the author in 2003 in the context of the non-linear realisation of the semi-direct product of E11 and its first fundamental representation. For all the fields we propose gauge transformations which are compatible with the underlying E11 structure. A crucial role is played by the generalised vielbein that the generalised space-time possess. We work out the explicit form of the gauge transformations, at low levels, in four, five and eleven dimensions.Comment: 33 page

The Formation of Giant Elliptical Galaxies and Their Globular Cluster Systems

The bimodal globular cluster (GC) metallicity distributions of many giant elliptical galaxies are often cited as evidence for the formation of such galaxies through mergers involving gas-rich spirals. In such models, the metal- rich GCs are assumed to have formed during the merger process. We explore an alternative possibility: that these metal-rich clusters represent the galaxy's intrinsic GC population and that the metal-poor component of the observed GC metallicity distribution arises from the capture of GCs from other galaxies, either through mergers or through tidal stripping. Starting with plausible assumptions for the initial galaxy luminosity function and for the dependence of GC metallicity on parent galaxy luminosity, we show that the growth of a pre-existing seed galaxy through mergers and tidal stripping is accompanied by the capture of metal-poor GCs whose properties are similar to those which are observed to surround giant ellipticals. We describe a method of using the observed number of metal-poor and metal-rich GCs to infer the merger histories of individual elliptical galaxies, and use this technique to derive limits on the number of galaxies and total luminosity accreted to date by M49. We argue that although GC specific frequency is conserved in galaxy mergers, the same may not be true of tidal stripping by the mean field of the host galaxy cluster. Comparisons of model GC metallicity distributions and specific frequencies to those observed for the well-studied galaxies M49 and M87 show that it is possible to explain their bimodal GC metallicity distributions and discordant specific frequencies without resorting to the formation of new GCs in mergers or by invoking multiple bursts of GC formation.Comment: 39 pages AAS Latex and 10 postscript figures.

Quantitative Economic Evaluations of HIV-Related Prevention and Treatment Services: A Review

Dr. Holtgrave and colleagues at the CDC set forth an extensive taxonomy of HIV prevention and treatment services and review reports of efforts to subject some of those services to formal economic evaluation. They find few services thus far to have been so evaluated, no evaluation to have focused solely upon behavioral outcomes and most economic evaluations to lack formal quantitative analyses

Generalised geometry, eleven dimensions and E11

We construct the non-linear realisation of E11 and its first fundamental representation in eleven dimensions at low levels. The fields depend on the usual coordinates of space-time as well as two form and five form coordinates. We derive the terms in the dynamics that contain the three form and six form fields and show that when we restricted their field dependence to be only on the usual space-time we recover the correct self-duality relation. Should this result generalise to the gravity fields then the non-linear realisation is an extension of the maximal supergravity theory, as previously conjectured. We also comment on the connections between the different approaches to generalised geometry.Comment: 17 pages, Trivial typos corrected in version one and a substantial note added which gives the equation of motion relating the gravity field to its dua

Scaling limit of a non-relativistic model

I calculate the structure function for scattering from the two-body bound state in its lowest level in a non-relativistic model of confined scalar ``quarks'' of masses $m_A$ and $m_B$. The scaling limit in $x={\bf q}^2/2(m_A+m_B)q^0$ exists and is non-vanishing only for the values $x=m_A/(m_A+m_B)$ and $x=m_B/(m_A+m_B)$ which correspond to the fractions of the momentum of the two-body system carried by each of the ``quarks.'' In the scaling limit, the interference from scattering off of the two ``quarks'' vanishes. Thus the scaling limit of this model agrees with the parton picture.Comment: 10 pages, 3 figures not included, in LaTex, UMD 92-22

Ethnic Minority Students in the UK: Addressing Inequalities in Access, Support, and Wellbeing in Higher Education

This chapter focuses on UK higher education and how structural racism is perpetuated through inadequate attention to access, support, and wellbeing. Inequalities in higher education correspond with those in health, where there are marked disparities between ethnic majority and ethnic minority populations, as COVID-19 revealed. The research employed a qualitative methodology to explore students’ experiences of higher education at a widening participation university during lockdowns resulting from COVID-19. Twenty undergraduate students participated in focus groups and semi-structured interviews across the academic year 2020–2021. These were audio recorded, transcribed, and coded using thematic analysis. The findings reveal that ethnic minority students suffered from inadequate access to technology, insufficient attention to child-care responsibilities, a dearth of peer-to-peer interactions, and limited institutional support for mental wellbe- ing. Inclusive support services and welcoming learning environments, including space for peer-to-peer learning, however, were emphasised as enablers for effective learning and emotional wellbeing. This study has shown that inequalities in access, support and wellbeing in higher education remain. Overcoming these inequalities requires equitable access and support provisioning for ethnic minorities so that all students can fulfil their potentials, at university and after
