    Website design quality and usage behavior: Unified Theory of Acceptance and Use of Technology

    Firms gain many benefits from well-designed websites. But which elements of website design quality really matter, and how do these elements influence usage behavior? With the Unified Theory of Acceptance and Use of Technology (UTAUT) as the theoretical foundation, this paper proposes that website design quality is a multi-dimensional construct with a higher-order structure that, when successfully incorporated into the UTAUT model, outperforms existing models. Results are based on a survey of 216 users of Internet banking. Findings indicate that the technical, general content and appearance dimensions of a website are most important for users. These dimensions are significantly related to usage behavior directly and indirectly. A halo effect may influence overall evaluation of a website because the dimensions of website design quality are interrelated. The implication is that improvements to the appearance of a website should enhance the overall evaluation of the site, leading to greater usage intentions

    Preferences of smart shopping channels and their impact on perceived wellbeing and social inclusion

    This study examines consumers’ interactions with retailers via three different shopping channels. Two of the channels are “smart” (technological) channels, comprising (i) where consumers shop using a computer and (ii) where consumers shop using a mobile phone. These two channels are compared with (iii) the traditional store channel. The paper explores the effect that consumers’ interactions with these channels have on their wellbeing, with a focus on individuals who perceive themselves as being socially excluded, for example, lacking access to goods, services and information. We make a connection between social exclusion and channel contribution to wellbeing for multiple channels, through the lens of the Theory of Planned Behaviour. The online survey findings (n=1368) indicate that for each channel, there is a higher contribution to wellbeing for that channel for people who are more socially excluded. Social exclusion can have many underlying causes, but channel contributions to wellbeing remain for consumers suffering financial stress and also those with mobility disability. For the mobile phone channel, the positive channel contributions to wellbeing are greater for younger than for older people. The paper outlines the implications for scholars and practitioners

    Folding model analysis of proton scattering from mirror nuclei 18^{18}Ne and 18^{18}O

    The elastic and inelastic scattering of protons from mirror nuclei 18^{18}Ne and 18^{18}O are studied in a folding model approach. For comparison, two different effective interactions are folded with Hartree-Fock densities to obtain the nuclear interaction potentials. Both of them provide equivalent descriptions to the data and the deformation parameters extracted from inelastic scattering are reasonable. The density dependence parameters obtained from nuclear matter calculations and used for present analysis also provide a good estimate for the nuclear mean free path. The present formalism unifies radioactivity, nuclear matter and nuclear scattering.Comment: 12 pages including 5 figure

    Nuclear Astrophysics in Rare Isotope Facilities

    Nuclear reactions in stars are difficult to measure directly in the laboratory at the small astrophysical energies. In recent years indirect methods with rare isotopes have been developed and applied to extract low-energy astrophysical cross sections.Comment: Invited talk (parallel section) at the Int. Conf.

    The incidence of myelodysplastic syndromes in Western Greece is increasing.

    Descriptive epidemiology of the myelodysplastic syndromes (MDS) is always interesting and may reveal time-dependent and geographical variations, as well as occupational exposure. Epidemiological data in Greece are not available by now. We have collected and analyzed medical records of all patients with a documented diagnosis of MDS, performed by an expert hematologist and/or hematopathologist, in the geographical area of Western Greece, during the 20-year period, defined between 1990 and 2009. We have then calculated and described demographic and clinical features of the diagnosed MDS patient population, and assessed the incidence and prevalence rates of MDS in Western Greece, during the above-mentioned period. A total of 855 patients with newly diagnosed MDS have been identified. Refractory anemia was the most common subtype in both FAB and WHO classification systems and in both genders. Del-5q and RARS were more commonly encountered among females, and the dysplastic subtype of chronic myelomonocytic leukemia among males. Trisomy 8 was the most common single cytogenetic abnormality. The crude mean annual incidence rate of MDS was 6.0 per 100,000 inhabitants aged ≥15 years old (all subtypes according to FAB), and it was 4.8 per 100,000 when CMML and RAEB-T were excluded. Crude incidence rate was higher in rural than in urban areas, but this finding was not confirmed after age standardization. Age-standardized mean annual incidence rate in men was 7.9/100,000 and in women 3.4/100,000. A continuously increasing incidence rate of MDS has been observed throughout the study period

    Study of the effects of Pauli blocking and Pauli non-locality on the optical potential

    Elastic scattering angular distributions for systems with reduced mass between 3 and 34 and energies varying between 25 and 120 MeV/nucleon were analyzed. The stable 4^4He, its exotic partner 6^6He, and the weakly bound 6,7^{6,7}Li nuclei were included as projectiles in the systematics. Optical model data analyzes were performed with an adjustable factor of normalization included in the imaginary part of the potential. These analyzes indicated a reduction of absorption for systems with small reduced masses that was detected due to the refractive nature of the scattering by light systems.Comment: 16 pages, 7 figure
