The acceptance of functional foods in Denmark, Finland and the United States: A study of consumers' conjoint evaluations of the qualities of functional foods and perceptions of general health factors and cultural values.

Functional foods is a relatively new concept covering food products enriched with various kinds of (natural) substances (eg vitamins, minerals or probiotic cultures) or modified so as to provide consumers with an additional physiological benefit presumed to prevent disease or promote health, without them having to change their eating habits fundamentally. 2. Health is one of the most important choice criteria, when consumers purchase food products. The fact that most health consequences of food are long term and therefore inaccessible at the time of purchase, the evaluation has to be based on nutritional information, eg health claims and other more accessible food qualities, eg taste, appearance, and processing method (when disclosed) which consumers may associate with health in one way or another. Consumers’ acceptance of functional foods therefore depends on the health information available as well as on their associations between wholesomeness and other qualities of functional foods. 3. Experience with functional foods introduced so far has disclosed national differences when it comes to consumer acceptance. One explanation may be that legislation on health claims varies across countries; another explanation may be differences in cultural values, which possibly lead to different associations between wholesomeness and other quality aspects, such as taste, convenience and method of processing. 4. Using conjoint analysis and survey questions (n=1500), the aim of the study presented in this paper is to investigate whether there are differences in the acceptance of functional foods in Denmark, Finland and the United States, and to which extent they are related to differences in consumers’ nutritional knowledge, health associations and cultural values. The general results of the study indicate that Finnish consumers accept functional foods more readily than do American and Danish consumers. In all three countries, however, the results also indicate that consumers are more positive towards enrichments with well-known nutritional effects and that the use of health claims, which are restricted by law in all three countries, has a potential, positive effect on the acceptance of functional foods.Consumer behaviour; evaluations; functional food; health factors; cultural values

On the Efficiency of Fast RSA Variants in Modern Mobile Phones

Modern mobile phones are increasingly being used for more services that require modern security mechanisms such as the public key cryptosystem RSA. It is, however, well known that public key cryptography demands considerable computing resources and that RSA encryption is much faster than RSA decryption. It is consequently an interesting question if RSA as a whole can be executed efficiently on modern mobile phones. In this paper, we explore the efficiency on modern mobile phones of variants of the RSA cryptosystem, covering CRT, MultiPrime RSA, MultiPower RSA, Rebalanced RSA and R Prime RSA by comparing the encryption and decryption time using a simple Java implementation and a typical RSA setup.Comment: 5 pages IEEE format, International Journal of Computer Science and Information Security, IJCSIS December 2009, ISSN 1947 5500, http://sites.google.com/site/ijcsis

MANUFACTURER AND RETAILER BRANDS IN FOOD RETAIL ASSORTMENTS Notes from a shopping trip across Europe

Food retailers present consumers with a complex market offering. They offer consumers an assortment of products sourced from numerous suppliers, along with various services within a retailer-controlled environment (Burt & Sparks 2002). Food retailers aim to offer an assortment of products and perform a variety of activities and services, which provide added value in the eyes of consumers (Burt 2000). In this connection, branding is becoming increasingly important, as food retailers develop their own brands within and across product categories. Many retailers are attempting to cultivate an overall brand identity in order to protect and identify their market offering (Burt & Sparks 2002). The assortment of products food retailers offer typically includes manufacturer brands, re-tailer brands and generic or unbranded products. In recent years, increasing competition in food retailing has made food retailers focus on whether they offer the "right" assort-ment to consumers. Under headings such as efficient consumer response (ECR) and cate-gory management (CM), retailers have been readjusting their assortments, delisting many brands that were deemed to be under-performing and including retailer branded products in an attempt to differentiate themselves by offering goods only available in their stores. Despite the importance of branding to retailers, the branding literature has focused on how manufacturers develop and maintain strong brands. Relatively little work has been done in the area of retail brands and even less about the interaction between retailer brands and manufacturer brands. In contrast, this paper develops a concept of retailer brand architecture, which captures that retailers typically offer an assortment of manu-facturer brands, retailer brands and generic products. In doing so we adapt the concept of brand architecture to a retail context. The concept of 'brand architecture', as originally developed by (Aaker & Joachimsthaler 2002), describes how the different brands used to market a range of products from the same manufacturer are related. The concept of brand architecture is based on the assumption that brands are not evaluated in isolation, but are placed in and evaluated within a broader context. This assumption is also important in a retail context. Consumers do not look at an isolated product or brand on the shelf. Their evaluation of the individual brand depends on the context; for instance, what other products are offered in the product category and in the retail outlet, previous experiences with the product or other products from the same manufacturer, as well as previous experiences with the retailer in question. In this paper, we take the concept of brand architecture and apply it to food retailers, con-ceptualising the brand architectures of food retailers as the portfolio of brands (gene-ric, retailer and manufacturer brands), which are included in the assortment of a retail concept (ie, a retail chain). In addition to developing a concept of 'retailer brand archi-tecture', we use this concept to investigate the brand architecture of a number of European food retailers in order to determine similarities and differences in brand architecture strategies. The paper is structured as follows: firstly, the concept of brand archi-tecture is presented. Secondly, the concept of brand architecture is applied to a retail setting and a number of other concepts important for understanding the brand architecture strategies of food retailers are introduced and discussed. Thirdly, the methodology used to investigate the brand architectures of European food retailers is discussed. Then, the findings from a shopping trip across Europe are presented. Finally, a discussion of the findings is provided and it is briefly considered how the findings of this study were used as input for a study of consumer perceptions of the brand architectures of food retailers. This subsequent study investigated whether consumers notice differences between the brand architectures of food retailers and how these are evaluatedNo keywords;

Votes at 16: do mock elections make a difference to adults’ attitudes?

Mock elections help 16- and 17-year-olds understand how elections work. But do they make adults more likely to back lowering the voting age to 16? Erik Gahner Larsen, Klaus Levinsen and Ulrik Kjær looked at the 2009 local elections in Denmark, when a number of municipalities held mock elections alongside the real ones. They found that they did make over-18s more positive about votes at 16, though a stubborn core of older and more right-wing voters remained hostile to the idea

Koens fysiologiske status og indflydelse heraf på produktion og sundhed omkring kælvning afhængig af foderniveau og næringsstofforsyning

Selvforsyning er ikke et regelkrav, men i tråd med det økologiske nærhedsprincip, dvs. at arbejde mest muligt i lukkede næringsstofkredsløb og dermed en fodring baseret på udelukkende hjemmeavlede fodermidler dyrket inden for bedriftens eget arealgrundlag. Det nuværende regelsæt har en minimumsgrænse for grovfodertildeling: 60% af tørstof i den daglige ration, dog 50% af tørstof til køer mindre end 3 måneder fra kælvning. I forbindelse med regelsættet er der imidlertid en række spørgsmål vedrørende dyrenes sundhed og produktion. På den baggrund er der gennemført forsøg med det formål at belyse produktion og metabolske parametre for tre typer 100% økologiske rationer baseret på korn, rapsfrø og kløvergræs dyrket på et givent areal pr. ko

Flow tilt angles near forest edges - Part 1: Sonic anemometry

An analysis of flow tilt angles from a fetch-limited beech forest site with clearings is presented in the context of vertical advection of carbon dioxide. Flow angles and vertical velocities from two sonic anemometers by different manufacturers were analyzed. Instead of using rotations, where zero-flow angles were assumed for neutral flow, the data was interpreted in relation to upstream and downstream forest edges. <br><br> Uncertainties caused by flow distortion, vertical misalignment and limited sampling time (statistical uncertainty) were evaluated and found to be highly significant. Since the attack angle distribution of the wind on the sonic anemometer is a function of atmospheric stratification, an instrumental error caused by imperfect flow distortion correction is also a function of the atmospheric stratification. In addition, it is discussed that the sonic anemometers have temperature dependent off-sets. These features of the investigated sonic anemometers make them unsuitable for measuring vertical velocities over highly turbulent forested terrain. By comparing the sonic anemometer results to that of a conically scanning Doppler lidar (Dellwik et al., 2010b), sonic anemometer accuracy for measuring mean flow tilt angles was estimated to between 2° and 3°. Use of planar fit algorithms, where the mean vertical velocity is calculated as the difference between the neutral and non-neutral flow, does not solve this problem of low accuracy and is not recommended. <br><br> Because of the large uncertainties caused by flow distortion and vertical alignment, it was only possible to a limited extent to relate sonic anemometer flow tilt angles to upwind forest edges, but the results by the lidar indicated that an internal boundary layer affect flow tilt angles at 21m above the forest. This is in accordance with earlier studies at the site. <br><br> Since the mean flow tilt angles do not follow the terrain, an estimate of the vertical advection term for near-neutral conditions was calculated using profile measurements of carbon dioxide. The estimated advection term is large, but it is not recommended to include it in the surface carbon balance, unless all terms in the carbon dioxide conservation equation can be precisely estimated

Instrumenting gait with an accelerometer: A system and algorithm examination

Gait is an important clinical assessment tool since changes in gait may reflect changes in general health. Measurement of gait is a complex process which has been restricted to the laboratory until relatively recently. The application of an inexpensive body worn sensor with appropriate gait algorithms (BWM) is an attractive alternative and offers the potential to assess gait in any setting. In this study we investigated the use of a low-cost BWM, compared to laboratory reference using a robust testing protocol in both younger and older adults. We observed that the BWM is a valid tool for estimating total step count and mean spatio-temporal gait characteristics however agreement for variability and asymmetry results was poor. We conducted a detailed investigation to explain the poor agreement between systems and determined it was due to inherent differences between the systems rather than inability of the sensor to measure the gait characteristics. The results highlight caution in the choice of reference system for validation studies. The BWM used in this study has the potential to gather longitudinal (real-world) spatio-temporal gait data that could be readily used in large lifestyle-based intervention studies, but further refinement of the algorithm(s) is required
