The importance of country images in the formation of consumer product perceptions

Abstract: Presents the results of a survey conducted among 194 retail salesmen of electronic equipment and 190 male consumers. According to salesmen, country of origin is a much less important attribute for shoppers of video‐cassette recorders and themselves than brand reputation. For the purpose of comparison, both salesmen and consumers provided direct evaluative judgements of 13 countries on their design and assembly capabilities, of three VCR brands and of the quality and purchase value of nine VCR conjoint profiles varying systematically with respect to country of design, country of assembly, brand, price and warranty. Salesmen’s direct importance weights were found to differ greatly from conjoint derived weights in that, in the latter case, country of origin cues had a significant and, with regard to quality perceptions, greater impact than the other attributes. Multiple regression models relating the direct perceptions of the countries of origin to brand evaluations indicate that the nesting of country perceptions in brand evaluation may partly explain this apparent inconsistency.

Non-destructive evaluation of concrete moisture by GPR: Experimental study and direct modeling

Abstract: This paper reports research into the application of Ground Penetrating Radar (GPR) technology to the physical characterization of concrete and gives the details and results of an experimental study on the effect of concrete moisture on radar waves propagating through concrete laboratory slabs. Radar measurements were performed using a commercial radar system with 1.5 GHz ground-coupled antennas. The concrete slabs were conditioned so as to possess different degrees of saturation and a homogeneous moisture distribution. Electrical resistivity measurements were also carried out on each concrete sample to provide complementary information regarding the moisture content of the concrete. Interesting results were found concerning the ability of the radar technique to characterize the moisture state of concrete. Attention was especially focused on the amplitude, velocity and frequency spectrum of the waveforms recorded. In particular, the behavior of the transmitter-receiver direct wave was found to be greatly influenced by the moisture in the concrete. Finally, some experimental results were simulated using a simple dielectric model of heterogeneous mixtures.

Recent Progress on the Photonic Properties of Conjugated Organometallic Polymers Built Upon the trans-Bis(para-ethynylbenzene)bis(phosphine)platinum(II) Chromophore and Related Derivatives

Abstract: This review article surveys the electronic and photophysical properties of conjugated organometallic polymers built upon the title compound and its related derivatives focussing primarily on systems investigated in our laboratories. The general structure of the polymers is (trans-bis(para-ethynylbenzene)bis(phosphine)platinum(II)-G)(n) where G is a conjugated group such as thiophene, fluorene, carbazole, substituted silole, quinone derivative, and metalloporphyrin residue, or a non-conjugated main-group moiety. Systems based on substituted phenylene units and other related fused rings are also discussed. The phosphine ligands are generally triethyl- or tri-n-butylphosphine groups. These trans-platinum(II) polymers and the corresponding model compounds are compared to the corresponding ortho-derivatives in the quinone series, and the newly prepared paracyclophane-containing polymers. For the porphyrin series, a comparison of fully conjugated oligomers exhibiting the general structure (trans-bis(para-ethynyl(zinc(porphyrin)))bis(phosphine)platinum(II))(n) (i.e., the C(6) H(4) group is absent from the main chain) will be made. This contribution also includes a description of the properties of the mononuclear chromophore itself, properties that define those of the polymers. Potential applications with regard to electronic and optical devices will be highlighted. These soluble and stable materials feature both the processing advantages of polymers and the functionality provided by the presence of metal centers. These multifunctional organometallic polyyne polymers exhibit convenient structural variability as well as optical and electronic properties, which renders them important for use in different research domains as chemical sensors and sensor protectors, as converters for light/electricity signals, and as patternable precursors to magnetic metal alloy nanoparticles.

Experienced continuity of care when patients see multiple clinicians: a qualitative metasummary.

Abstract: PURPOSE Continuity of care among different clinicians refers to consistent and coherent care management and good measures are needed. We conducted a metasummary of qualitative studies of patients' experience with care to identify measurable elements that recur over a variety of contexts and health conditions as the basis for a generic measure of management continuity. METHODS From an initial list of 514 potential studies (1997-2007), 33 met our criteria of using qualitative methods and exploring patients' experiences of health care from various clinicians over time. They were coded independently. Consensus meetings minimized conceptual overlap between codes. RESULTS For patients, continuity of care is experienced as security and confi - dence rather than seamlessness. Coordination and information transfer between professionals are assumed until proven otherwise. Care plans help clinician coor- dination but are rarely discerned as such by patients. Knowing what to expect and having contingency plans provides security. Information transfer includes information given to the patient, especially to support an active role in giving and receiving information, monitoring, and self-management. Having a single trusted clinician who helps navigate the system and sees the patient as a partner undergirds the experience of continuity between clinicians.
