The Chinese art of graphic design is much affected by eastern and western cultural trends and artistic styles in concept, function and in the form of semantic and performance.

Two studies were carried out in production systems and associated pig management practises. A participatory rural appraisal （PRA）, involving 279 pigs-keeping households in nine villages and a cross sectional survey using a random sample of 300 pig farmers in 30 villages of the study districts, were used to collect data. Important economic activities were crop farming, livestock keeping, petty business, casual labour and artisan works in that order. The mean farm size and number of pigs per household was 2 ± 2.7 ha and 4.9 ±4.2 pigs, respectively. The largest categories of pig herd structure were breeding females followed by piglets. Age, marital status, household size and land size of household head had significant influence on the pig herd size （P 〈 0.05）. Pig farmers practised three main types of pig management systems, namely, total confinement, semi confinement and free range/herding. Each system had specific management practices in relation to feeding and housing. The frequencies of these systems varied significantly （P 〈 0.01） by socio-economic factors, such as, educational status of household head, land size and herd sizes of pigs, goats and cattle. The authors recommend effective use of locally available resources and careful consideration of existing farming systems for sustainable development of smallholder pig production.展开更多

One of the most famous attempts to overcome this dualism is the structuration theory of Anthony Giddens, and alongside this is found the conception of social realism of Roy Bhaskar and Margaret Archer. Their efforts to link individualistic and holistic approaches are based on a varifocal attempt to explain the theoretical issues from both individualistic and holistic perspectives. The author of this article believes that there is an alternative solution to this problem, where both perspectives are ＂blended＂ in a theoretical explanation demonstrating that the concepts which we use in sociological theory--actor, action and structure--are inherently of dualistic nature, i.e., they are ＂duplex＂.展开更多
