Technology readiness and the evaluation and adoption of self-service technologies

s companies struggle to persuade their customers to adopt new self-service technologies (SSTs), it has become increasingly important to understand the factors affecting customers’ attitudes towards these SSTs and their adoption behaviour. Technology readiness (TR), i.e. the customer's mental readiness to accept new technologies, has been proposed as such a factor. TR comprises four dimensions: innovativeness, optimism, discomfort and insecurity. This article investigates the effects of TR on customers’ (1) attitudes towards using SST for airline check-in, (2) adoption of self-service check-in, and (3) evaluations of a new self-service check-in on the Internet, in terms of perceived service quality, satisfaction and loyalty. An empirical study was conducted among loyalty program customers of a European airline, having access to Internet check-in. Data were collected with online and traditional mail surveys, resulting in 1258 usable responses. Analysis of the data revealed that only optimism and innovativeness formed unique individual dimensions. Furthermore, TR had surprisingly little impact on customer attitudes towards SST, on adoption behaviour, and on SST evaluations. Optimism explained consumer behaviour towards SSTs best, whereas innovativeness had only a marginal effect on attitudes towards using the Internet or a mobile phone to check-in. The article concludes with a discussion of the validity of the TR construct and suggestions for future research. Managerial implications are provided. [less ▲]

Tectonic vs. shallow origin of geodetically inferred ground movements: an NE Ardenne (Belgium) case

In order to get a better insight into the temporal pattern of height change variations in a moderately seismic intraplate area, a 1 km long section has been weekly leveled from April, 21, 1997 to January, 12, 1998 in NE Ardenne (Belgium). As this section is located very close to a small reservoir of 25 X 10(6) m(3), it also allowed the influence of lake level variations on the nearby ground motion to be studied. The measured height difference variations show a maximum amplitude of 3.45 mm, with weekly values not exceeding 1 mm. A two-dimensional (2D) finite element modeling confirms that waterload variations in the lake are the primary cause of movement of the section, inducing maximum ground subsidence of about 2 cm and seasonal tilting of 3-4 mu rads within a range of 2-3 km. We also show that a fault passively alters the spatial distribution of the waterload-dependent movements. The removal of this component from the observed ground motion leaves oscillating residual displacements characterized by an amplitude of 1-1.5 mm and a 'period' of about 2 months. We demonstrate that these displacements are independent of rainfall and probably of groundwater fluctuation too. Although most of the residual motions take place on the fault straddled by the leveling section, no credible mechanism can be found to ascribe these motions to a tectonic process.

Few diseases exhibit such regional variability in their epidemiology, even in an area as limited as Belgium, as tinea capitis. Thus, anthropophilic tinea capitis is highly predominant in areas where new immigrants from Black Africa and North Africa have settled. By contrast, zoophilic tinea capitis is found largely in areas where the cat population is infected. Kerion often affects professions in which contact with infected livestock is involved. Prevention of tinea capitis thus has distinct regional features. Treatment, on the other hand, has a universal basis. [less ▲]

TEL is a gene frequently involved in specific chromosomal translocations in human leukemia and sarcoma that encodes a member of the ETS family of transcriptional regulators. TEL is unusual among other ETS proteins by its ability to self-associate in vivo, a property that is essential to the oncogenic activation of TEL-derived fusion proteins. We show here that TEL is a sequence-specific transcriptional repressor of ETS-binding site-driven transcription of model and natural promoters. [less ▲]

The formation of a transient network by sulfonato polyisoprene and sulfonato polystyrene in toluene is studied using static and dynamic light scattering and dynamic mechanical analysis. It is shown that at low concentrations aggregates are formed with increasing molar mass and polydispersity as the polymer concentration is increased. Above a certain concentration well below the overlap concentration of the polymer chains (C*), a transient network is formed. This is characterised by a plateau modulus at high frequencies and a relatively narrow viscoelastic relaxation time distribution. The intensity auto-correlation function of the transient network shows two relaxational modes: a relatively fast diffusional mode close to the co-operative diffusional mode of semidilute solutions of the unfunctionalised polymers, and a slow broader mode which becomes independent of the scattering angle at concentrations close to C*. The relation between this slow mode and the viscoelastic relaxation is discussed. [less ▲]
