Positioning Janus nanoparticles in block copolymer scaffolds

The periodic domains formed by block copolymer melts have been heralded as potential scaffolds for arranging nanoparticles in 3d space, provided we can control the positioning of the particles. Recent experiments have located particles at the domain interfaces by grafting mixed brushes to their surfaces. Here the underlying mechanism, which involves the transformation into Janus particles, is investigated with self-consistent field theory using a new multi-coordinate-system algorithm.

Conceptualising and measuring the equity of online brands

Although brand equity is an important source of competitive advantage online, previous conceptualisations and measures overlook the unique characteristics of the internet that render consumers co-creators of brand value. In view of this, a threephased research programme was undertaken to identify the facets of online retail/service (ORS) brand equity and then develop and validate a scale for its measurement. ORS brand equity was found to be a second order construct with five correlated yet distinct dimensions: emotional connection, online experience, responsive service nature, trust, and fulfilment. A series of tests showed that the ensuing 12-item scale has strong psychometric properties. The implications of this research for marketing researchers and practitioners are discussed.

Dimensionalising on- and off-line brands' composite equity

This paper approaches the subject of brand equity measurement on and offline. The existing body of research knowledge on brand equity measurement has derived from classical contexts; however, the majority of today's brands prosper simultaneously online and offline. Since branding on the Web needs to address the unique characteristics of computer-mediated environments, it was posited that classical measures of brand equity were inadequate for this category of brands. Aaker's guidelines for building a brand equity measurement system were thus followed and his brand equity ten was employed as a point of departure. The main challenge was complementing traditional measures of brand equity with new measures pertinent to the Web. Following 16 semi-structured interviews with experts, ten additional measures were identified.

Developing a brand performance measure for financial services brands

With no universal approach for measuring brand performance, we show how a consumer-based brand measure was developed for corporate financial services brands. Churchill's paradigm was adopted. A literature review and 20 depth interviews with experts suggested that brand loyalty, consumer satisfaction and reputation constitute the brand performance measure. Ten financial services organisations provided access to their consumers. Following a postal survey, 600 questionnaires were analysed through principal components analysis to identify the consumer-based measure. Further testing revealed this to be a valid and reliable brand performance measure.

Memo to marketers: quantitative evidence for change: how user-generated content really affects brands

Developed in response to the new challenges of the social Web, this study investigates how involvement with brand-related user-generated content (UGC) affects consumers’ perceptions of brands. The authors develop a model that provides new insights into the links between drivers of UGC creation, involvement, and consumer-based brand equity. Expert opinions were sought on a hypothesized model, which further was tested through data from an online survey of 202 consumers. The results provide guidance for managerial initiatives involving UGC campaigns for brand building. The findings indicate that consumer perceptions of co-creation, community, and self-concept have a positive impact on UGC involvement that, in turn, positively affects consumer based brand equity. These empirical results have significant implications for avoiding problems and building deeper relationships between consumers and brands in the age of social media.

Cloud based global positioning system as a safety monitor for dementia patients

The aim of using GPS for Alzheimer's Patients is to give carers and families of those affected by Alzheimer's Disease, as well as all the other dementia related conditions, a service that can, via SMS text message, notify them should their loved one leave their home. Through a custom website, it enables the carer to remotely manage a contour boundary that is specifically assigned to the patient as well as the telephone numbers of the carers. The technique makes liberal use of such as Google Maps.

Strategic positioning and grand strategies for high-technology SMEs

Firm size is found to affect strategic decisions significantly, whereas technology and market stability stimulate product development and innovation.

Made in Italy. Made in Britain. Quality, brands and innovation in the European poultry market, 1950-1980.

This paper compares the development of the poultry industry in Italy with the UK. Earlier research has suggested that the UK poultry industry developed a symbiotic relationship with the emerging supermarket retailers. Italy had a retarded supermarket sector. Its distribution system favoured small-scale, independent butchers rather than chains of self-service supermarkets. Despite this the Italian poultry industry also modernised, adopting US technologies. The catalyst for this modernisation was technological innovation in refrigeration technologies that enabled Italian consumers and independent retailers to be persuaded of the merits of the new ‘technological’ chicken. While the Italian market has become dominated by AIA and Amadori in recent years, the key innovators were the entrepreneurs that created the company called Arena.

Evaluation of positioning error-induced pixel shifts on satellite linear push-broom imagery

Georeferencing is one of the major tasks of satellite-borne remote sensing. Compared to traditional indirect methods, direct georeferencing through a Global Positioning System/inertial navigation system requires fewer and simpler steps to obtain exterior orientation parameters of remotely sensed images. However, the pixel shift caused by geographic positioning error, which is generally derived from boresight angle as well as terrain topography variation, can have a great impact on the precision of georeferencing. The distribution of pixel shifts introduced by the positioning error on a satellite linear push-broom image is quantitatively analyzed. We use the variation of the object space coordinate to simulate different kinds of positioning errors and terrain topography. Then a total differential method was applied to establish a rigorous sensor model in order to mathematically obtain the relationship between pixel shift and positioning error. Finally, two simulation experiments are conducted using the imaging parameters of Chang’ E-1 satellite to evaluate two different kinds of positioning errors. The experimental results have shown that with the experimental parameters, the maximum pixel shift could reach 1.74 pixels. The proposed approach can be extended to a generic application for imaging error modeling in remote sensing with terrain variation.
