EXAMINING FOOD CONSUMPTION IN JAPAN UNDER LIFE-CYCLE HYPOTHESIS: IMPLICATION FROM CROSS-SECTIONAL DATA

This study estimates a cross-sectional model through a theoretically consistent Almost Ideal Demand System (AIDS) to examine the economic and demographic determinants of food consumption patterns in Japan over life-cycle periods. Results show key factors that explain such behavior, including family size, number of children, lifestyle and health concern.Research Methods/ Statistical Methods,

Food Consumption and Demographics in Japan: Implications for an Aging Population

This study estimates a cross-sectional model based on the Almost Ideal Demand System (AIDS) to examine the determinants of food consumption patterns in Japan over life-cycle periods. The test of structural changes, the analysis of the effects of demographic characteristics, and the estimation of expenditure and price elasticities are conducted from a random sample of 1,281 households from a Japanese household survey in 1997. Results show that each economic or non-economic factor has a different impact on food consumption over a lifetime. Changes in consumption of some food groups can be explained by price and income effects where others can be explained by demographic characteristics. Financial constraint is not binding and residential location is likely to have little or no impact on predicting consumers’ food choices at different periods of their lives. Other key factors that affect consumption pattern include family size, number of children, lifestyle and health concern.Japan, Food Demand, Life-Cycle, AIDS, Household

Nonmatrix varieties of nonassociative algebras

A variety of associative algebras is called nonmatrix if it does not contain the algebra of 2 x 2 matrices over the given field. Nonmatrix varieties were introduced and studied by V.N.Latyshev in relation with the Specht problem. Some characterizations of nonmatrix varieties were obtained in the paper [10]. In the given paper the notion of nonmatrix variety is extended for nonassociative algebras, and the characterization from [10] is generalized for alternative, Jordan, and some other varieties of algebras

Revisão bibliográfica sobre a sinergia entre Lean Production e Ergonomia

Neste artigo apresenta-se uma revisão bibliográfica e propõe-se uma reflexão acerca dos aspectos ergonómicos envolvidos na aplicação das técnicas de Lean Production (LP). Lean Production é um modelo organizacional de produção que procura a redução dos custos através da eliminação dos desperdícios em toda a cadeia de valor. Nesta eliminação procuram-se também formas de reduzir esforços do trabalhador o que vai de encontro à Ergonomia. Esta disciplina preocupa-se com a saúde e o bem-estar humano no trabalho e em simultâneo com o desempenho global do sistema. Lean Production foi o modelo de produção adoptado pela empresa Toyota nos anos 50 no Toyota Production System e representou uma alternativa ao sistema tradicional de produção, baseado no Taylorismo/Fordismo. Para que esse sistema seja efetivado são utilizadas técnicas, tais como sistema JIT, Jidoka, técnica kanban, layout celular e setup rápido. Este artigo analisa como estas técnicas podem contribuir para a Ergonomia dos postos de trabalho e desta forma, para a saúde e segurança dos colaboradores, fomentando uma relação sinergética entre Lean Production e Ergonomia que conduz à melhoria do desempenho global
