Relationships between optimum stimulation level and willingness to use mass customisation options

Mass customisation, defined as the mass production of individually customised goods and services, aims at providing products and services that are more suited to the needs or desires of today’s fragmented consumer markets. Mass customisers should identify how needs or desires of the fragmented market shape the customisation of not just the product and service, but also the mass customisation experience. Towards this end, the authors examined whether an individual’s preferred level for environmental stimulation defined as optimum stimulation level (OSL) was associated with the types of products, services and experiences desired from mass customisation of apparel. As the authors hypothesised, OSL had significant positive correlations with willingness to use co‐design services to create a unique design, trying co‐design as an exciting experience, overall commitment to using co‐design, and trying body scanning as an exciting experience. OSL did not have significant correlations with the more banal willingness to use body scanning services for better fitting products or overall commitment to using body scanning. There was also a significant positive correlation between OSL and interest in customising experiential products, but not between OSL and interest in customising utilitarian products, as hypothesised. Results support research of the influence of OSL on consumer behaviour. Implications for the industry include considering experience aspects and environmental stimulation when developing a mass customisation programme.

Acceptance of Mass Customization of Apparel: Merchandising Issues Associated With Preference for Product, Process, and Place

The purpose of our research was to examine apparel merchandising issues associated with mass customization. A questionnaire was developed to explore preferences for mass customization product, process, and place that have the potential of affecting success of a mass customization program. The questionnaire was administered to a convenience sample of 131 college students. Data were analyzed using descriptive statistics, t-tests, McNemar tests, within-subject ANOVA, and Bonferroni multiple comparisons. Successful mass customization of apparel at retail is dependent on identification of appropriate dimensions of product, process, and place. Our implications address merchandising issues associated with customer involvement in customizing design and fit of apparel products in retail store settings.

Enzymatic control of the metabolic activity of Pseudomonas aeruginosa grown in glucose or succinate media

Abstract Pseudomonas aeruginosa ATCC 9027 lacks phosphofructokinase and therefore does not have a functional Embden-Meyerhof pathway. However, it possesses the enzyme complement to carry out gluconeogenesis through the reversal of the Embden-Meyerhof pathway reactions. Glucose did not repress the enzymes of the tricarboxylic acid cycle. The results show that the tricarboxylic acid cycle plays a significant role in the metabolism of succinate apart from its essential biosynthetic role. The significance of a unique control pattern of glucose-metabolizing enzymes in Pseudomonas aeruginosa as compared to that found in coliforms and aerobic spore-forming bacilli is discussed.

Digital Apparel Design Process: Placing a New Technology Into a Framework for the Creative Design Process

Design methodology and process are studied in different contexts and diverse fields. Designing has the potential to generate new knowledge and is intimately tied to new technologies, such as digital textile printing. These open up a constantly expanding range of creative possibilities, and generate a complex set of decision points for designers. In this paper we show how the design process is impacted and how new products can be created through exploration of the limits and potentials of digital technologies for textile and apparel design. Changes in design approach were analyzed through four design phases with five design projects. The design process was shown to change as various technical problems were evaluated and solved with each successive garment design. What began as a sporadic process that centered on solving sub-problems, evolved to a linear design progression with increased time spent in creative conceptualization.

Instrument development and evaluation for measuring USA apparel product design attributes

Purpose – The research goal is to develop, analyze, and evaluate an instrument measuring perceptions and preferences of garment design characteristics, and to evaluate interpretability of results for ease of use by scientists and industry practitioners.Design/methodology/approach – This study focused on female garment attributes that were culturally inspired by Indonesia. A sample of 115 US college‐age females was targeted to test 18 garments varying in attributes of three styles, three fabric prints, and two fabric colorways. Attributes were used as stimuli in generating evaluations of garment similarities and acceptance.Findings – Stimuli and questions performed well in collecting data, and convergence validity for the instrument was demonstrated through hierarchical cluster analyses and multidimensional scaling analysis. Findings from this initial testing determined that consumers can differentiate similarity and evaluate levels of acceptance for garment style, fabric print, and color.Research limitati...

ENDOGENOUS METABOLISM OF PSEUDOMONAS

Because of the quantitative importance of the endogenous respiration of obligate aerobic bacteria, it has been usual to attempt to reduce the reserve materials in the cells and to correct for the endogenous activity that might continue during substrate oxidation. Some of the accepted techniques for lowering endogenous respiration were applied to Pseudomonm aeruginosa ATCC 9027. It was found that regardless of the growth medium, resting cell suspensions exhibited a high rate of endogenous activity as measured by oxygen uptake studies. It was also found that cells harvested from the logarithmic growth phase exhibited the same rate of endogenous oxygen uptake as cells from the stationary phase. Aeration of resting cell suspensions for six hours or storage for up to five days in ice, followed by centrifugation of the cells and resuspension in fresh phosphate buffer, did not decrease the rate of endogenous oxygen uptake (TABLE 1). In fact the rate of respiration increased in spite of a pronounced decrease in the number of viable cells as determined by the Standard Methods Plate Count. One might conclude from all of these observations that the substrate or substrates of endogenous respiration are present in maximum concentration, even in cells that are in the logarithmic growth phase; that one cannot grow cells that are devoid of this reserve substrate; and that starvation of the cells does not specifically reduce the reserves. The material which most readily fulfills all of these criteria is some constituent essential to the cell or the entire cellular protoplasm. One might further conclude that the phenomenon of endogenous respiration in P . aeruginosa is merely the attrition of the cell as it is forced to oxidize some of its normal cellular constituents.

OXIDATIVE ASSIMILATION OF GLUCOSE BY PSEUDOMONAS AERUGINOSA

Duncan, Margaret G. (The University of British Columbia, Vancouver, British Columbia, Canada) and J. J. R. Campbell. Oxidative assimilation of glucose by Pseudomonas aeruginosa. J. Bacteriol. 84:784-792. 1962-Oxidative assimilation of glucose by washed-cell suspensions of Pseudomonas aeruginosa was studied using C(14)-labeled substrate. At the time of glucose disappearance, only small amounts of radioactivity were present in the cells, and alpha-ketoglutaric acid accumulated in the supernatant fluid. Most of the material synthesized by the cells during oxidative assimilation was nitrogenous, the ammonia being supplied by the endogenous respiration. The cold trichloroacetic acid-soluble fraction and the lipid fraction appeared to be important during the early stages of oxidative assimilation, and the largest percentage of the incorporated radioactivity was found in the protein fraction. In the presence of added ammonia, assimilation was greatly increased and no alpha-ketoglutaric acid was found in the supernatant fluid. Sodium azide partially inhibited incorporation into all major cell fractions, and at higher concentrations depressed the rate of glucose oxidation. During oxidative assimilation, chloramphenicol specifically inhibited the synthesis of protein. Oxidative assimilation of glucose by this organism did not appear to involve the synthesis of a primary product such as is found in the majority of bacteria.

Species Specificity of sRNA's and Aminoacyl-sRNA Synthetases in some Aerobic Bacteria.

Abstract The compatability of the sRNAs and the aminoacyl-sRNA synthetases of two strains of Pseudomonas aeruginosa , and one each of Pseudomonas fluorescens , Achromobacter sp., and Saccharomyces cerevisiae was determined with a view to assessing the usefulness of this relationship as a taxonomic aid. The pattern of reactions obtained with the heterologous systems indicated that this would not be helpful in taxonomic studies since the enzymes of Escherichia coli appeared to react as well with Ps. aeruginosa sRNA as did those of Achromobacter and Ps. fluorescens . The yeast systems however, were relatively incompatible with those of all of the bacteria.
