This study explores the changing nature of filial piety in contemporary society in rural China. With the economic, social and political upheavals that followed the Revolution, can 'great peace under heaven' still be found for the rural Chinese family as in the traditional Confucian proverb,"make yourself useful, look after your family, look after your country, and all is peaceful under heaven"? This study explores this question, in terms not so much of financial prosperity, but of non-tangible cultural values of filial piety, changing familial and gender roles, and economic migration. In particular, it examines how macro level changes in economic, social and demographic policies have affected family life in rural China. The primary policies examined were collectivisation, the hukou registration system, marketization, and the One-Child policy. Ethnographic interviews reveal how migration has affected rural family structures beyond the usual quantifiable economic measures. Using the village of Meijia, Sichuan province, as a paradigmatic sample of family, where members have moved to work in the cities, leaving their children behind with the grandparents, the study demonstrates how migration and modernization are reshaping familial roles, changing filial expectations, reshuffling notions of care-taking, and transforming traditional views on the value of daughters and daughters-in-law. The study concludes that the choices families make around migration, child-rearing and elder-care cannot be fully explained by either an income diversification model or a survival model, but rather through notions of filial piety. Yet the concept of filial piety itself is changing, particularly in relation to gender and perceptions about the worth of daughters and the mother/ daughter-in-law relationship. Understanding these new family dynamics will be important for both policy planners and economic analysts.

Increasing time trends in the recorded incidence of childhood cancer have been reported in many different settings. The extent to which these trends reflect real changes in incidence, rather than improvements in methods for diagnosis and registration, is controversial. Using data from the National Registry of Childhood Tumours (NRCT), this thesis investigates time trends in cancer diagnosed under age 15 in residents of Britain during 1966-2005 (54650 cases), and considers potential sources of artefact in detail. Several different methods are used to estimate completeness of NRCT registration. The history of methods for diagnosis and registration of childhood cancers in Britain is described, and predictions are made for effects on recorded incidence. For each of the 12 main diagnostic groups, Poisson regression is used to fit continuous time trends and ‘step’ models to the annual age-sex-standardised rates by year of birth and year of diagnosis. Age-specific rates by period, and quinquennial standardised rates for diagnostic subgroups, are shown graphically. For three broad groups (leukaemia, CNS tumours and other cancer), geographical variation is compared by period of diagnosis. The results of these analyses are discussed in relation to the predicted artefacts. The evidence for a positive association between affluence and recorded incidence of childhood leukaemia is briefly reviewed. A special form of diagnostic artefact, the ‘fatal infection’ hypothesis, is proposed as an explanation of both this association and the leukaemia time trend. This hypothesis is examined in a novel test based on clinical data. The recorded incidence of childhood cancer in Britain increased in each of 12 diagnostic groups during 1966-2005 (from 0.5% per year for bone cancer to 2.5% for hepatic cancer, with 0.7% for leukaemia). Evidence presented here suggests that these increases are probably artefacts of diagnosis and registration. The potential implications for epidemiological studies of childhood cancer should be considered.

Castration has a long temporal and geographical span. Its origins are unclear, but likely lie in the Ancient Near East around the time of the Secondary Products Revolution and the increase in social complexity of proto-urban societies. Due to the unique social and gender roles created by castrates’ ambiguous sexual state, human castrates were used heavily in strongly hierarchical social structures such as imperial and religious institutions, and were often close to the ruler of an imperial society. This privileged position, though often occupied by slaves, gave castrates enormous power to affect governmental decisions. This often aroused the jealousy and hatred of intact elite males, who were not afforded as open access to the ruler and virulently condemned castrates in historical documents. These attitudes were passed down to the scholars and doctors who began to study castration in the late 19th and early 20th centuries, affecting the manner in which castration was studied. Osteometric and anthropometric examinations of castrates were carried out during this period, but the two World Wars and a shift in focus meant that castrate bodies were not studied for nearly eighty years. Recent interest in gender and sexuality in the past has revived interest in castration as a topic, but few studies of castrate remains have occurred. As large numbers of castrates are referenced in historical documents, the lack of castrate skeletons may be due to a lack of recognition of the physical effects of castration on the skeleton. The synthesis and generation of methods for more accurate identification of castrate skeletons was undertaken and the results are presented here to improve the ability to identify castrate skeletons within the archaeological record.
