Building brands through experiential events: when entertainment meets education

Experiential marketing is increasingly getting companies’ attention as a strategy to interact with consumers and engage them to better convey their brand image and positioning. However, its effects are still unclear both at the aggregate and at the individual levels. This paper addresses this topic and presents a field experiment investigating the effects of experiential marketing on brand image in retailing. Two similar consumer electronics stores with different strategies – traditional vs. experiential – constitutes the setting in which a field experiment has been run. Two similar samples of consumers took part in our study by visiting one of these two stores, and answering a questionnaire before and after the visit with the primary goal to investigate the brand image and its changes due to the shopping visit. Brand image was measured as the overall brand attitude – via four items – and five specific desired brand claims that the company wanted to convey to consumers. Findings show that engaged consumers through the multisensory and interactive event arranged in the experiential store register higher levels of both brand attitude and all brand claims than those visiting the traditional store, and that the increase in both the dependent variables after the visit of the experiential store is higher than the increase in the traditional store. Thus, experiential stores are not only able to entertain consumers, but they are also able to educate them, by conveying them a set of brand claims more effectively than the traditional stor

Planning the digitisation, storage and access of large scale audiovisual archives

This paper presents ongoing work in PrestoSpace on how broadcast archives can plan large-scale, long-term digitization and storage projects. In our approach, carrier decay, technical obsolescence, and rapidly falling costs of mass storage are represented as a series of statistical and predictive models. The models include ongoing migration within a digital archive. The objective is to allow archive managers to investigate the trade-offs between how many items to transfer, the cost of transfer and storage, how long it will take, what quality can be achieved, how much will be lost, and what digital storage solutions to adopt over time. The process and models are based on digitization projects conducted by large broadcast archives that are currently migrating their collections into digital form. Whilst our focus is on broadcast archives, our findings should be readily transferable to other scenarios where there is a need to store large volumes of digital data over long periods of time

Silicon MINP solar cells

The MINP solar cell concept refers to a cell structure designed to be a base region dominated device. Thus, it is desirable that recombination losses are reduced to the point that they occur only in the base region. The most unique feature of the MINP cell design is that a tunneling contact is utilized for the metallic contact on the front surface. The areas under the collector grid and bus bar are passivated by a thin oxide of tunneling thickness. Efforts must also be taken to minimize recombination at the surface between grid lines, at the junction periphery and within the emitter. Results of both theoretical and experimental studies of silicon MINP cells are given. Performance calculations are described which give expected efficiencies as a function of base resistivity and junction depth. Fabrication and characterization of cells are discussed which are based on 0.2 ohm-cm substrates, diffused emitters on the order of 0.15 to 0.20 microns deep, and with Mg MIS collector grids. A total area AM 1 efficiency of 16.8% was achieved. Detailed analyses of photocurrent and current loss mechanisms are presented and utilized to discuss future directions of research. Finally, results reported by other workers are discussed

Study of orbiter/payload interface communications configuration control board directive from an operational perspective

Orbiter/payload data and communications interface was examined. It was found that the Configuration Control Board Directive (CCBD) greatly increases the capability of the orbiter to communicate with a wide variety of projected shuttle payloads. Rather than being derived from individual payload communication requirements, the CCBD appears to be based on an operational philosophy that requires the orbiter to duplicate or augment the ground network/payload communication links. It is suggested that the implementation of the CCBD be reviewed and compared with the Level 1 Program Requirements Document, differences reconciled, and interface characteristics defined

Investigation of high efficiency GaAs solar cells

Investigations of basic mechanisms which limit the performance of high efficiency GaAs solar cells are discussed. P/N heteroface structures have been fabricated from MOCVD epiwafers. Typical AM1 efficiencies are in the 21 to 22 percent range, with a SERI measurement for one cell being 21.5 percent. The cells are nominally 1.5 x 1.5 cm in size. Studies have involved photoresponse, T-I-V analyses, and interpretation of data in terms of appropriate models to determine key cell parameters. Results of these studies are utilized to determine future approaches for increasing GaAs solar cell efficiencies

Electro-optical characterization of GaAs solar cells

The electro-optical characterization of gallium arsenide p/n solar cells is discussed. The objective is to identify and understand basic mechanisms which limit the performance of high efficiency gallium arsenide solar cells. The approach involves conducting photoresponse and temperature dependent current-voltage measurements, and interpretation of the data in terms of theory to determine key device parameters. Depth concentration profiles are also utilized in formulating a model to explain device performance

A Feature-Augmented Grammar for Automated Media Production

The IST Polymnia project is creating a fully automated system for personalised video generation, including content creation, selection and composition. This paper presents a linguistically motivated solution using context-free feature-augmented grammar rules to describe editing tasks and hence automate video editing. The solution is media and application independent

Density and distribution on enset root mealybugs on enset

The enset root mealybug (Cataenococcus ensete Williams and Matile-Ferrero) has become the most important insect pest of enset (Ensete ventricosum) in southern Ethiopia. The objective of this study was to determine the distribution and density of enset root mealybugs on enset plants. The distribution of the enset root mealybug on enset roots and corms of the ‘Genticha’ clone was studied in 2005 on farmers’ field at Yirgachefe, southern Ethiopia. An average of 87 adult enset root mealybugs were collected from roots and corms per plant. Themajority of the mealybugs inhabited the roots (79%), while 21% was found on the corms. About 99% of the mealybugs were found in the upper 40 cm soil layer. In addition, about 90% of the mealybugs were collected within a 60 cm radius from the plants. The majority of the mealybugs (59%) were found on the upper half of the corm. About 63% of all mealybugs were collected from the corm and on the roots within a 20 cm radius from the corm. Both root and shoot fresh weight had a negative correlation (r2 = 0.58 and 0.92, respectively) with the ensetroot mealybug population density

GaAs solar cells for laser power beaming

Efforts to develop GaAs solar cells for coupling to laser beams in the wavelength range of 800 to 840 nm are described. This work was motivated primarily by interests in space-tp-space power beaming applications. In particular, the Battelle Pacific Northwest Laboratories is conducting studies of the utilization of power beaming for several future space missions. Modeling calculations of GaAs cell performance were carried out using PC-1D to determine an appropriate design for a p/n cell structure. Epitaxial wafers were grown by MOCVD and cells fabricated at WSU Tri-Cities. Under simulated conditions, an efficiency of 53 percent was achieved for a cell coupled to 806 nm light at 400 mW/sq cm
