AU - Nowlin, K. AU - Summers, T.A. AU - Xu, Y. T2 - Journal of Fashion Marketing and Management AB - The domestic exotic leather industry (for the purposes of this study exotic leather was defined as ostrich, emu and American alligator) has been in existence for many years, but much of the raw leather is exported, resulting in a loss of value added for America. The purpose of this study was to explore fashion leaders’ and followers’ attitudes towards exotic leather apparel products. The theoretical framework used for this study was Sproles’ model of fashion adoption (Sproles 1979). This study was part of a larger research project which was designed to segment the market, profile consumers of exotic leather apparel products and develop promotional strategies. A questionnaire, mailed to 800 fashion professionals in eight regional fashion centres across the country, yielded a 50 per cent return rate. Results indicated that the Sproles model was effective in describing and characterising fashion leaders (adopters) and followers (Sproles 1979). Fashion leaders had a more favourable attitude towards exotic leather apparel products, had a greater purchase intention of such products, had higher cognitive motivations, and had a different shopping orientation from followers. Leaders enjoyed shopping more and were not as cost‐conscious, traditional, or conservative as followers. Understanding the differences between fashion leaders and followers will only serve to enhance and contribute to the economic development of the domestic exotic leather industry.

Multinational discounters such as Wal‐Mart and Carrefour have been vying against Korean discounters for market share with the full liberalization of the distribution sector in 1997. This study examined various aspects of discount store retailing (store attributes, shopping costs) and consumers’ shopping motives, values, and retail outcomes (e.g. shopping excitement, satisfaction and repatronage intention), to understand Korean consumers’ discount store patronage. Significant differences were found in store image perceptions and shoppers’ internal orientations between multinational discount store patrons vs Korean discount store patrons. Theoretical and managerial implications are discussed.

AU - Kim, J.O. T2 - Journal of Global Marketing AB - Abstract This study examined the effects of consumers' internal shopping motives and external store attributes on excitement that shoppers may experience at discount stores in Korean markets and the mediating impact of excitement on selected behavior outcomes. Among three types of shopping motives (socialization, utilitarian and diversion), diversion significantly affected the level of excitement that shoppers experienced at the discount store. Store attributes of facility-related convenience and a neat, spacious atmosphere had an impact on shoppers' excitement at the discount stores. Excitement positively affected shoppers' satisfaction and repatronage intentions in discount store retailing in Korea. The empirical study results have major implications for multinational retailers as well as for future research in the area of international retailing.

T2 - ACS Symposium Series AB - We have begun to fabricate polymer films whose compositions, structures, and properties may be developed and controlled during their formation with inclusion compounds (ICs). ICs formed with either urea(U) or cyclodextrin(CD) hosts and containing guest polymers or small-molecule additives are embedded into carrier polymer films either by solution casting or melt pressing methods. Once embedded, the IC crystals are left undisturbed or are disrupted by solvent treatment, which removes the host (U or CD), but not the carrier polymer nor the coalesced IC-guest. In this manner polymer-polymer composite and additive-filled films have been fabricated. Employment of polymer-U or CD-ICs produces composite films containing two different polymers or two populations of the same polymer. In the latter case, the morphologies of the carrier and IC-coalesced chains may differ, because of chain-folded and chain-extended crystallization, respectively. We may, for example, control film permeabilities by either controlling the compositions or the morphologies of DA - 2001/// PY - 2001/// DO - 10.1021/bk-2001-0790.ch014 VL - 790 ER - TY - JOUR TI - Consumer purchase data as a strategic product development tool AU - May-Plumlee, T.

To obtain accurate physical measurements, a basic knowledge and set of skills are required that are not often found in the average salesperson at a retail clothing outlet. The development of three‐dimensional body‐scanning technologies may have significant potential for use in the apparel industry, particularly for customisation or mass customisation strategies to be employed. The purpose of this study was to review all the 3D body scanning systems currently available and to determine the underlying principles that allow these systems to work. Specifications of each system were compared in order to provide some direction for further research into the integration of these systems with current apparel CAD pattern design or pattern generation technologies.

The dyeing behaviour of cotton that had been rendered cationic by reaction with 2,3‐epoxypropyltrimethylammonium chloride was examined. Dye yields and fastness properties are reported for a number of direct, reactive and acid dyes with the modified fibre. Excellent dye yields and colour fastness properties were obtained without the use of electrolytes, multiple rinsings or fixation agents which are normally employed in cotton dyeing.

The formulation constitutes an integrated analysis of the three regions, which permits a study of the yarn path and related tension distributions for unwind points away from the two ends of the package. The numerical solutions presented reveal a very complex interaction between several of the nondimensional parameters characteristic of the problem. The complexity arises from the problem's nonlinear nature, whose solutions exhibit a bifurcation phenomenon and consequent inherent instabilities. In brief, we argue that heuristic discussions about the physics of the problem in dimensional space can be extremely misleading.

The IrTe2 polymorphs included in our analysis are three known phases, i.e., the polymeric CdI2-type, pyrite-type, and monoclinic IrTe2 phases, as well as four hypothetical phases, i.e., ramsdelite-type, pyrolusite-type, IrS2-type, and marcasite-type phases. The charge balances of these IrTe2 phases were analyzed by carrying out extended Hückel tight-binding electronic band structure calculations for the crystal structures optimized by VASP calculations.

The observed changes in vibrational properties below the 45 K transition support a weak lattice distortion in combination with a spin gap in this material. The spin-exchange interaction is predicted to occur primarily along the (−a +b) diagonal direction, in good agreement with the spectral data. In addition, notable frequency shifts of vibrational modes point to a second transition between 100 and 200 K. The low-lying electronic excitation in the stack direction (assigned as a charge-transfer feature based upon our electronic band structure calculations) shows distinct changes with temperature that are consistent with trends in the vibrational spectrum. The pattern of a high-temperature transition preceding the spin-Peierls transition is discussed in relation to other low-dimensional organic and inorganic materials.

The renewed interest can be partially attributed to the availability of powerful computing tools needed to solve problems of this kind. This paper is the first of a series of papers reporting results of ongoing research at NCSU. In this paper, apart from a critical evaluation of some recently published work, the physics of unwinding as proposed by earlier publications is examined through extensive parametric studies. That is, two parameters of high practical importance, balloon shape and unwinding tension, are calculated as functions of the direction of unwinding (from front-to-back and back-to-front), wind angle, residual tension in the yarn on the package, and the coefficient of yarn-package drag. In addition, limitations of a two-region analysis are addressed.

The crystal structure of this salt was determined by single crystal X-ray diffraction at 298 and 150 K, its physical properties were examined by electrical resistivity, Raman spectroscopy and EPR measurements, and its electronic structure was calculated and compared with that of the analogous salt β″-(ET)2SF5CH2CF2SO3. Whereas β″-(ET)2SF5CHFCF2SO3 has disordered anions and undergoes a metal-to-insulator transition at ∼190 K, β″-(ET)2SF5CH2CF2SO3 has ordered anions and is semiconducting down to ∼100 K, metallic below ∼100 K, and superconducting below 5 K. At room temperature both β″-(ET)2SF5CHFCF2SO3 and β″-(ET)2SF5CH2CF2SO3 have similar electronic band structures and physical properties. When the temperature is lowered, each donor molecule stack becomes dimerized in both salts. However, the interdimer interaction within each donor stack nearly vanishes in β″-(ET)2SF5CHFCF2SO3, but remains substantial in β″-(ET)2SF5CH2CF2SO3.

Residual waxes influence fiber–fiber bonding, reducing the paper properties of recycled OCC as well as the paper machine operating efficiency. A procedure to dewax OCC is a major objective of the paper industry. Here we describe a novel process to quantitatively dewax OCC by using supercritical carbon dioxide to remove the wax. The results obtained for the extraction of both saturated and curtain‐coated waxed containers are reported and compared with Soxhlet extraction with hexane. Quantitative removal of the waxes was obtained under a variety of operating conditions. Gas chromatographic analysis of the extracted paraffin wax shows that supercritical fluid extraction does not chemically alter the paraffin wax, indicating the recovered wax may be recycled. © 2001 John Wiley & Sons, Inc.

These complexes were prepared by a solution-heating technique. Their structural features were observed with the use of: FTIR, TGA, WAXS, and 13C-NMR. FTIR identifies absorption peaks of the guest polymer molecules in the cyclodextrin. Thermal decomposition shows that the ICs have a higher thermal stability than the pure γ-cyclodextrin. The wide angle X-ray diffraction of the complexes indicates that the ICs form channel structures. CP-MAS 13C-NMR spectra of the ICs show that γ-cyclodextrin, in the presence of a polymer guest, adopts a more symmetric conformation when compared to its pure state.

We examined the magnetic structures of these compounds and their isostructural analogue Cu(Mo(0.25)W0.75)O4 on the basis of the spin-orbital interaction energies calculated for their spin dimers. Our study shows that these compounds consist of two-dimensional (2D) magnetic sheets defined by one superexchange (intrachain Cu-O-Cu) and three super-superexchange (interchain Cu-O.O-Cu) paths, the strongly interacting spin units of these 2D magnetic sheets are the two-leg antiferromagnetic (AFM) ladder chains running along the (a + c)-direction, and the spin arrangement between adjacent AFM ladder chains leads to spin frustration. The similarities and differences in the magnetic structures of CuWO4, CuMoO4-III, and Cu(Mo(0.25)W0.75)O4 were discussed by examining how adjacent AFM ladder chains are coupled via the superexchange paths in the 2D magnetic sheets and how adjacent 2D magnetic sheets are coupled via another superexchange paths along the c-direction. Our study reproduces the experimental finding that the magnetic unit cell is doubled along the a-axis in CuWO(4) and along the c-axis in CuMoO4-III and predicts that the magnetic unit cell should be doubled along the a- and b-axes in Cu(Mo(0.25)W0.75)O4. In the understanding of the strength of a super-superexchange interaction, the importance of the geometrical factors controlling the overlap between the tails of magnetic orbitals was pointed out.

The magnetic orbital of each Cu2+ site in CuM2O6 is given by the “x2–y2” orbital so that the magnitude of an antiferromagnetic spin exchange interaction for a given spin dimer increases when the arrangement of the nearest-neighbor square-planar CuO4 units containing the magnetic orbitals provides a good sigma overlap between the adjacent magnetic orbitals. The one-dimensional magnetic chains of α-CuV2O6, β-CuNb2O6, and α-CuNb2O6 run along a direction different than their edge-sharing CuO4 chain directions. Our study predicts that the antiferromagnetic ordering in β-CuNb2O6 should make the magnetic unit cell double the chemical unit cell along the b-direction.

To find what kinds of surface relaxation can cause such STM images, we carried out partial density plot calculations for the unrelaxed structure and a number of model relaxed structures of the rutile TiO2(1 1 0) surface with oxygen vacancies using the extended Hückel tight binding method. We also performed density functional theory calculations to estimate the Ti atom displacements for the three types of Ti atoms present on TiO2(1 1 0) surfaces with oxygen vacancies.

The levels of errors in instrumental colour measurements and in visual assessments were similar to those of previous workers. The random and large scattering nature of the trend of unit lightness tolerances with lightness ( L *) has made it difficult to apply a nonlinear lightness weighting calculation, e.g., that of CMC(ℓ:c). The chroma position corrected hue tolerances have shown a weak trend with hue‐angle ( h ab ) and it can be incorporated in the existing modified CIELAB formula, e.g., CIE94, to improve its performance. Among the six formulae (CIELAB, CMC, CIE94, LCD, BFD‐II, and DCI‐95) tested, the LCD (Leeds Colour Difference) formula that is a modified model of the CIE94 colour‐difference equation has given the best performance. More visual experimental results are still thought to be required for further development in industrial colour‐difference evaluation. © 2001 John Wiley & Sons, Inc.

We examined the probable cause for this observation on the basis of tight-binding band electronic structure calculations for BaIrO3. In support of the experimental observation, our calculations show that BaIrO3 should be regarded as a weakly localized metal above 175 K, its t2g-block band density of states has a sharp peak at the Fermi level, and its Fermi surfaces have partially nested pieces.

On the basis of this analysis we explored how the anomalous magnetic and transport properties of Sr6V9S22O2 can be explained. Our work shows that the × superstructure is not caused by a charge density wave instability associated with Fermi surface nesting but by the metal−metal bonding through the shared edges of adjacent VS6 octahedra. The weak and strong electron localizations observed for Sr6V9S22O2 were discussed in terms of three-center two-electron and two-center two-electron V−V bonds in the 1T-VS2 layers.

Taking the z axis as parallel to the CuO4 chains, we ascribe the absorption edge in the magnetic chain direction to O 2px, 2py → singly filled Cu 3d transitions and the edge in the transverse direction to O 2pz → singly filled Cu 3d excitations. The dual slope in the transverse direction is a direct consequence of the double maximum in the O 2pz density of states. The influence of Zn and Si doping on the electronic spectra of CuGeO3 is analyzed as well. Whereas neither impurity affects the phonon-assisted d−d band, Si doping smears the charge-transfer gap. This smearing of the gap by interchain impurity substitution is attributed to random distortions of the crystalline lattice giving rise to structurally induced changes in the electronic properties.

The variabilities of single-end strengths found in six different ring spun and open-end yarns are successfully decomposed into random and processinduced variance components by tolerancing the variances of the matching fiber length and tensile properties. A total of 43,080 single-end yarn strength tests, 4,200,000 AFIS® fiber lengths, and over 70,000 Mantis® single-fiber tensile tests are performed for the required parameter estimation, simulation, and model validation. The results confirm that variance tolerancing through “effective gauge length” and other intrinsic components is effective for variance estimation and decomposition. Most significant is that the processinduced variances account for 69-82% of the total yarn strength variations, signifying the importance of and challenges in controlling and reducing process variances in spun yarn manufacturing.

T2 - Journal of the American Chemical Society AB - Using dc magnetization, ac susceptibility, specific heat, and neutron diffraction, we have studied the magnetic properties of Mn[N(CN)2]2(pyz) (pyz = pyrazine) in detail. The material crystallizes in the monoclinic space group P2(1)/n with a = 7.3248(2), b = 16.7369(4), and c = 8.7905 (2) A, beta = 89.596 (2) degrees, V = 1077.65(7) A(3), and Z = 4, as determined by Rietveld refinement of neutron powder diffraction data at 1.35 K. The 5 K neutron powder diffraction data reflect very little variation in the crystal structure. Interpenetrating ReO3-like networks are formed from axially elongated Mn(2+) octahedra and edges made up of mu-bonded [N(CN)2](-) anions and neutral pyz ligands. A three-dimensional antiferromagnetic ordering occurs below T(N) = 2.53(2) K. The magnetic unit cell is double the nuclear one along the a- and c-axes, giving the (1/2, 0, 1/2) superstructure. The crystallographic and antiferromagnetic structures are commensurate and consist of collinear Mn(2+) moments, each with a magnitude of 4.15(6) mu(B) aligned parallel to the a-direction (Mn-pyz-Mn chains). Electronic structure calculations indicate that the exchange interaction is much stronger along the Mn-pyz-Mn chain axis than along the Mn-NCNCN-Mn axes by a factor of approximately 40, giving rise to a predominantly one-dimensional magnetic system. Thus, the variable-temperature magnetic susceptibility data are well described by a Heisenberg antiferromagnetic chain model, giving g = 2.01(1) and J/k(B) = -0.27(1) K. Owing to single-ion anisotropy of the Mn(2+) ion, field-induced phenomena ascribed to spin-flop and paramagnetic transitions are observed at 0.43 and 2.83 T, respectively.

T2 - Textile Research Journal AB - A variance tolerancing method is developed as a means for separating and estimating random errors associated with raw materials and yarn structures from process-induced errors based on structural relationships governing the strength of a spun yarn. The method is successfully used to estimate the mean and variance of spun yarn strength by propagating the statistical parameters of fiber properties onto those of the resulting spun yarns. In developing the new estimation procedure, probabilistic models based on the distributions of fiber length and tensile properties are combined with geometric and structural models of fiber arrangements in spun yarns. For the first time, the concept of “effective gauge length” is used to model and simulate the breakage process of spun yarns. The new concept and specific methodology are aimed at better controlling process and product characteristics by quantifying the variances according to their sources.
