Peasant children in sixteenth‐century Castile helped their families with various domestic chores and agropastoral jobs. Used as unpaid workers, they enabled the typical peasant family to diversify its activities, and often to raise its standard of living. Hired juvenile workers were also quite important in Golden Age Castile. These seemingly entered the job market because their own families lacked the resources to enable them to remain at home. The experience of active participation in productive activities served all juvenile workers, whether paid or unpaid, as a sort of apprenticeship in preparation for adult membership in the peasant community.  相似文献

Compared with the divisive views of the past, integrative thinking has recently come to characterise the methodological debate on poverty. ‘Qualitative vs quantitative’ has given way to ‘qual–quant’; ‘cross-disciplinarity’ has replaced ‘economics vs anthropology’. This article attempts to review this change. It begins with a historical overview of the pure economic approach to poverty and its critique. The critique, both from within economics and from the participatory and anthropological disciplines, is examined, and recent trends are considered. The current ‘qual–quant’ approach is illustrated with examples, and the author concludes that the future may well see the emergence of a ‘participatory qual–quant’ approach.  相似文献

We present an accidental autoerotic asphyxiation of a 24-year-old man. Further investigation revealed that 18 years earlier, his brother, then 13, had been found dead, hanging in the family bathroom. Although that death had been ruled a suicide, reevaluation of the death scene indicates that this was also an autoerotic asphyxiation. This is the first reported case of sexual asphyxia involving siblings.  相似文献

As the result of a previous study many laboratories have used XAM neutral medium-improved white mounting medium in textile fibre examination for more than 20 years. Due to European Directive 98/79/EC, XAM is no longer available and an alternative needed to be found. A list of desirable properties was formulated and a number of mounting media were tested against this. Entellan New was identified as the best mounting medium, and performed similarly to XAM in all aspects.  相似文献

Electrophoretic analysis of seminal gamma-glutamyl transpeptidase (GGT) activity of 147 unrelated Japanese males revealed three types of band patterns. An anodal single band, a cathodal single band and heterozygous double bands termed 1, 2 and 2-1, respectively, were commonly identified in the samples. The frequencies of the three types were 1 = 0.22, 2 = 0.33 and 2-1 = 0.44. Seminal stains kept for more than 6 months revealed distinguishable band patterns as well as fresh samples.  相似文献
