    Notizen: State-of-the-art market segmentation often involves simultaneous consideration of multiple and overlapping variables. These variables are studied to assess their relationships, select a subset of variables which best represent the subgroups (segments) within a market, and determine the likelihood of membership of a given individual in a particular segment. Such information, obtained in the exploratory phase of a multivariate market segmentation study, leads to the construction of more parsimonious models. These models have less stringent data requirements while facilitating substantive evaluation to aid marketing managers in formulating more effective targeting and positioning strategies within different market segments. This paper utilizes the information-theoretic (IT) approach to address several issues in multivariate market segmentation studies. A marketing data set analyzed previously is employed to examine the suitability and usefulness of the proposed approach [12]. Some useful extensions of the IT framework and its applications are also discussed.

    Notizen: Conformational changes in bovine serum albumin (BSA), Ca++-free α-lactalbumin(apo-α-lac), and Ca++-saturated α-lactalbumin(holo-ct-lac) were examined via Fourier transform infrared (FTIR) spectroscopy after pressure treatment up to 1270 MPa. BSA showed minimal irreversible secondary structural changes with pressurization, showing a slight loss of β-sheet structure in favor of α-helix. Apo-α-lac underwent major irreversible changes and exhibited infrared bands characteristic of aggregation upon decompression. Holo-α-lac showed extensive resistance to high pressure with no major structural changes. The rich disulfide content in BSA and the presence of Ca++ in holo-α-lac may play important roles in stabilizing these proteins against pressure denaturation.
