A stochastic approach to the estimation of the prevalence of IUD: Example of Taiwan,Republic of China

Assuming three patterns of changes in number of new IUD insertions, three stochastic models have been developed for the estimation of the “prevalence” of IUD in situ at a given point of time. The advantages of these models, compared with the conventional ways of estimating IUD prevalence, rest with their ease of use and simplicity of method for calculating variances of the estimates. The models are also useful for family planning administrators to set program targets. A correction factor to estimate the number of IUDs which, although “currently in situ,” are worn by women who have “passed over” the upper age limit of their reproductive spans has also been developed. This is particularly useful in estimating the “effective retention” of IUD.     

The island-wide family planning programme in Taiwan: Analysis of the accomplishments of the past eight years

Abstract Taiwan's island-wide family planning programme is the showcase of similar programmes in the developing world. In the past eight years, between 1964 and 1971, a cumulative total of 935,000 married women accepted the Lippes loop, 236,000 accepted the pill, and 116,000 couples accepted condoms. The prevalence rates of loop and pill users at the end of 1971 are estimated at 18·7 per cent and 3-6 per cent respectively. The programme had been recruiting more younger women of lower parity to practise family planning which is desirable, but a fact of concern is that a large proportion of the acceptors had had at least one son, and had accepted the methods to stop, rather than to space births. The 'life expectancy' of loop and pill, the two major contraceptives recommended in the programme, have been shorter than expected, 31·4 months without and 49·9 months with re-insertion for the loop, and only 10·5 months without re-taking for the pill. The concepts of 'half-life (retention)' and 'half-life (impact)', developed by the author, were applied in the analysis to obtain the values of 18·6 months and 25·7 months respectively for the loop, and 5·8 months and 9·2 months respectively for the pill all for the first segment. Only nine per cent of the total current loop wearers were aged 40-44 in 1964, but the proportion had increased substantially, to 20·5 per cent, in 1971. This 'ageing' of current users tends to minimize the demographic impact of the programme which is a factor of concern. Methods to overcome this and other problems should be explored for the final success of the programme.     

What Changes MSW Students' View on the Mission of Social Work?

Little is known about how professional social work education affects students' view on the social work mission. Using a secondary analysis of larger longitudinal data collected from masters in social work (MSW) students in California, USA, this study sought to explore the relationship among the students' demographic characteristics, their primary reasons for pursuing an MSW degree, and their view on the mission of social work at the time of entering an MSW program, whether the students' view on the mission of social work changed in the course of an MSW education, and factors contributing to a change of MSW students' view on the social work mission—individual adaptation vs societal change—between the beginning and the end of the MSW program. The results showed that students' degree of social action involvement, type of field practicum, and ideological variables predicted students' view changes or adherence between entering the MSW program and graduating.     

Correlates of Quality of Life in New Migrants to Hong Kong from Mainland China

The concept of Quality of life (QOL) has received considerable attention from different disciplines. The aim of this study was to identify what are the correlates of QOL among Chinese new immigrants in Hong Kong. Data were collected through a cross-sectional survey among 449 Hong Kong new immigrants from Mainland China. Bivariate and multiple regression analyses were performed to examine the association between immigrants’ QOL and their demographic characteristics, socio-economic factors, optimism, sense of control, perceived social support, perceived neighborhood disorder, collective efficacy, pre-migration planning, depressive symptoms and acculturation stress. Our findings demonstrated that depressive symptom is the most prominent factor in reducing immigrants’ level of QOL, perceived social support and optimism are the two important factors that enhance the QOL of these depressed immigrants. Our results indicate that preventive measures must be developed, and professional counseling and psychological support services must be provided to new immigrants in Hong Kong, especially those who have depressive symptoms.     

University Binge Drinking Patterns and Changes in Patterns of Alcohol Consumption Among Chinese Undergraduates in a Hong Kong University

Abstract

Objective: To examine patterns of binge drinking and changes in drinking patterns among Chinese university students. Participants and Methods: Responses to an anonymous questionnaire were compared between a random sample of 411 second year Chinese undergraduate students in 2006 and 2,630 first year students from the previous year. Students reporting any symptoms of alcohol abuse were classified as alcohol abusers whereas those reporting repeated inability to curtail use were categorized as alcohol dependent. Results: After 1 year of university, greatly increased rates of past-month drinking of different degrees were found in both genders. Binge drinking among second year undergraduates was significantly correlated with male gender, living in a student residence hall, smoking, drinking to relieve stress, and having friends who frequently drank. Conclusions: Alcohol misuse is a health hazard to Chinese students in a university environment. Proactive policies aimed at preventing harmful alcohol use should be considered by university authorities.     

Demographic change and the labour share of income

Despite similar levels of per capita income, education and technology, the development of labour income shares in OECD countries has displayed different patterns since 1960. The paper examines the role of demography in this regard. We first use a standard overlapping generations model to derive the mechanisms by which demographic change can affect the labour share. It turns out that demographic change can affect the labour share either by altering the domestic capital intensity, by causing factor-biased technological change or in a small open economy framework by creating a gap between domestic savings and investments. The latter affects the country’s investments abroad and in return its net foreign asset income which directly leads to changes in the labour share. Empirical estimations based on these insights, provide evidence that an increases in the expected retirement durations and old-age dependency ratios as well as declines in labour force growth rates have indeed been major forces behind the decline in labour shares that took place in many countries. These effects tend to be larger in open economies and pension reforms towards a funded pension system seem to have accelerated the effects.     

The Annual Demand for Seasonal Immigrant Labor in Greece and its Influence on the Entrance of Albanian Workers

The paper investigates the annual inflow of legal immigrants in Greece the last 6?years, 2005?C2010, on the basis of the demand of Greek employers for seasonal immigrant labor in provenance from non-European Union countries. This process is determined by the new legislative framework described by the Law 3386/2005 on the entrance, accommodation and social integration of third-country nationals in the Greek territory. Every year Greek authorities determine the maximum number of residence and work permits that will be given to non-EU immigrants. Permits concern mainly seasonal jobs and profited basically to Albanian workers. Local needs for work determine the number of immigrants on the local level. Local demand is expressed through prefectures (Greece is divided administratively in 54 prefectures). The local needs determine the national demand, and therefore the annual inflow, for legal economic immigrants from non-EU countries. The paper analyses the evolution of this demand and tries to explain the factors that influence this evolution; are they mainly structural or they are related to economic activity? The analysis is based on a prefectural level because it permits a more qualitative approach of the evolution since we can have a more specific result. It appears that some prefectures, especially at the region of Central Macedonia, concentrate the main part of the annual demand for seasonal workers from third countries, basically Albanian workers. This demand is oriented to land workers, mainly for agricultural work. It appears that unemployment has only limited influence on this demand.     

Automated Measurement of Facial Expression in Infant–Mother Interaction: A Pilot Study

Automated facial measurement using computer vision has the potential to objectively document continuous changes in behavior. To examine emotional expression and communication, we used automated measurements to quantify smile strength, eye constriction, and mouth opening in two 6‐month‐old infant‐mother dyads who each engaged in a face‐to‐face interaction. Automated measurements showed high associations with anatomically based manual coding (concurrent validity); measurements of smiling showed high associations with mean ratings of positive emotion made by naive observers (construct validity). For both infants and mothers, smile strength and eye constriction (the Duchenne marker) were correlated over time, creating a continuous index of smile intensity. Infant and mother smile activity exhibited changing (nonstationary) local patterns of association, suggesting the dyadic repair and dissolution of states of affective synchrony. The study provides insights into the potential and limitations of automated measurement of facial action.
