Encouraging the implication of shops in the city by means of retail associationism. The case of Bilbao

[EN] Retail activity in urban areas constitutes a key variable in the health of a city. For that reason, the processes of urban revitalization and retail revitalization run in parallel manner. Integrated management models for urban centres constitute a good framework to harness the competitiveness of the cities and their retail businesses, but they require of all implied participation, by means of a public – private cooperation.

Marcas de distribuidor: análisis del espacio en el lineal por categorías y enseñas

[ES] El objetivo principal de este trabajo es confirmar si la ocupación de espacio por parte de las marcas de distribuidor en los lineales es excesivo, tal y como parecen afirmar los productores de marcas de fabricante. Para ello, se presentan los resultados de una observación del espacio ocupado por estas marcas en una muestra representativa de 40 categorías en 55 establecimientos. Con los datos obtenidos, se muestran las diferencias existentes entre categorías y entre enseñas. Además se observa si los establecimientos han llegado a un punto de lineal máximo y si el espacio ocupado por sus marcas propias es desproporcionado en relación a su cuota de mercado.

Survey of the fatty acid composition of Canadian beef: Backfat and longissimus lumborum muscle

[EN]A survey of Canadian retail beef was undertaken with emphasis on the trans fatty acid (TFA) and conjugated linoleic acid (CLA) isomers, and compared with current health recommendations. Thirty striploin steaks were collected in the winter and summer from major grocery stores in Calgary (Alberta, Canada). Steak fatty acid compositions (backfat and longissimus lumborum muscle analysed separately) showed minor seasonal differences with lower total saturates (PB0.05) and higher total monounsaturates (PB 0.01) in winter, but no differences in total polyunsaturated fatty acids. The ratio of n-6 and n-3 polyunsaturated fatty acid in longissimus lumborum averaged 5.8. The average TFA content in longissimus lumborum was 0.128 g 100 g_1 serving size, and 10t-18:1 was found to be the predominant isomer (32% of total trans), while vaccenic acid was second most abundant (15% of total trans). The CLA content in longissimus lumborum was similar to that of backfat, ranging from 0.43 to 0.60% of total fatty acids and rumenic acid represented 60% of total isomers. Overall, there is still room for improvement in the saturated, mono- and polyunsaturated fatty acid composition of Canadian beef to meet general dietary guidelines for human consumption and additional targets should include reducing 10t-18:1 while increasing both rumenic and vaccenic acids.

Aplicando netnografía a la obtención del mapa de posicionamiento para empresas de distribución alimentaria

[ES] Las comunidades online se han convertido en un lugar de encuentro muy popular para los consumidores que les permite compartir información. En este artículo se presenta una técnica de información novedosa como la netnografía, y se aplica para determinar cuál es el posicionamiento de las empresas de distribución alimentaria. Tras la recogida y análisis de 506 mensajes válidos de la comunidad online Ciao, se pudo conocer qué atributos se asociaban a seis establecimientos de alimentación analizados. Mercadona se asocia con la calidad de su marca de distribuidor y una escasa variedad de marcas/productos. Las tiendas discount, Lidl y DIA, destacan por la posibilidad de mejora en la limpieza del establecimiento y la localización de los productos. Los hipermercados, Eroski, Alcampo y Carrefour, son destacados por su variedad de marcas/productos, y alejado del domicilio. También se ha identificado a los competidores más directos de cada empresa, encontrándose una competencia entre los formatos de venta del mismo tipo (intratipo). El uso de la netnografia, técnica relativamente reciente, supone la mayor originalidad del trabajo. Además, las conclusiones obtenidas, que son coincidentes con estudios anteriores, muestran que la netnografía puede ser una fuente de información para determinar cuál es la imagen comercial y el posicionamiento de las empresas.

Otimização do problema de localização de instalações aplicado ao comércio e distribuição de combustíveis

Um dos problemas mais relevantes em organizações de grande porte é a escolha de locais para instalação de plantas industriais, centros de distribuição ou mesmo pontos comerciais. Esse problema logístico é uma decisão estratégica que pode causar um impacto significativo no custo total do produto comercializado. Existem na literatura diversos trabalhos que abordam esse problema. Assim, o objetivo desse trabalho é analisar o problema da localização de instalações proposto por diferentes autores e definir um modelo que seja o mais adequado possível ao mercado de distribuição de combustíveis no Brasil. Para isso, foi realizada uma análise do fluxo de refino e distribuição praticado neste segmento e da formação do respectivo custo de transporte. Foram consideradas restrições como capacidade de estoque, gama de produtos ofertados e níveis da hierarquia de distribuição. A partir dessa análise, foi definido um modelo matemático aplicado à redução dos custos de frete considerando-se a carga tributária. O modelo matemático foi implementado, em linguagem C, e permite simular o problema. Foram aplicadas técnicas de computação paralela visando reduzir o tempo de execução do algoritmo. Os resultados obtidos com o modelo Single Uncapacited Facility Location Problem (SUFLP) simulado nas duas versões do programa, sequencial e paralela, demonstram ganhos de até 5% em economia de custos e redução do tempo de execução em mais de 50%.

Quality of fish in retail markets of Bombay

Study carried out on the quality of fresh fish in retail markets of Bombay revealed that only 75% of the samples were of acceptable quality. Incidence of faecal streptococci was generally high, indicating poor sanitary and hygienic practices in handling of fresh fish. Total bacterial counts higher than Indian standard specified limits were observed in more than one third of the samples analysed. 7.5% of the samples were found to be contaminated either with Salmonella or Clostridium perfringens, thus posing a serious potential health hazard to the consumer. The quality of fish in different markets is also discussed. The urgent need for formulation and implementation of quality standards for fresh fish in domestic trade is highlighted.

Retail prices of split, smoked, dried bream and dried Lake Tanganyika sardines at Lusaka markets, 1968-1970

This paper reports the results of a retail price survey at Lusaka markets on split, smoked, dried bream (Tilapia spp.) in 1968-69 and dried Lake Tanganyika sardines (Limnothrissa miodon and Stolothrissa tanangicae) in 1969-70. During the survey periods the average prices of these products maintained a level 70% to 130% higher than those fixed by the Government. Price fluctuations in relation to season, size and quality of the products were discussed. The prices were affected by season and size of the products but not by quality in terms of appearance and smell of the non-cooked products.

Analysis of competition in the wholesale and retail markets for fish in Kisumu, Kenya

This study analyses competition in the wholesale and retail fish marketing system in Kisumu, which is Kenya's largest fish market. It is based on cross sectional and time series primary data collected in a survey involving 88 retailers and 47 wholesale traders of fish in the town. Stratified random sampling method was used in selecting the respondents, Concentration ratios, Lorenz curves and Gini coefficients are derived and evaluated for both markets. They demonstrate that market shares are unequally distributed among the wholesalers and retailers. The Gini coefficients are 0.37 and 0.45 for the whole and retail markets respectively. Based on a Gini coefficient cut-off level of 0.4, it is concluded that the wholesale fish market exhibits effective competition while the retail outlet has oligopolistic tendencies. The implication of this level of competition to price efficiency is discussed. Intervention measures to enhance competition in the market are recommended.
