Trajectory of problem behaviours of Korean adopted children: using piecewise hierarchical linear growth modelling

This study examined the trajectory of problem behaviours in domestically adopted children in South Korea as they aged. This study used the Panel Study on Korean Adopted Children's longitudinal, three‐wave data (2006, 2008 and 2010). Although data were collected at three time points, our data consisted of six time points, which covered the 5–10 years age range of the adopted children at the time of survey. One hundred sixty‐four children were included in the analysis, 75 of whom contributed to one time point, 74 to two time points and 15 to three time points. The trajectory of the problem behaviours of adopted children was examined using a piecewise hierarchical linear growth model. Because the initial exploration of the data suggested non‐linear changes in behaviour problems over time, we split the growth trajectory into two time periods: Time 1 (5–7 years) and Time 2 (7–10 years). A two‐rate model was used to estimate separate slopes for the two time periods. Results showed that the externalizing and internalizing problems of adopted children have different trajectories. Internalizing problems did not show significant changes after 5 years of age, while externalizing problems increased until 7 years of age and decreased significantly thereafter.     

A note on the Cauchy-type mixture distributions

An interesting class of continuous distributions, called Cauchy-type mixture, with potential applications in modelling erratic phenomena is introduced by Soltani and Tafakori [A class of continuous kernels and Cauchy type heavy tail distributions. Statist Probab Lett. 2013;83:1018–1027]. In this work, we provide more insights into the Cauchy-type mixture distributions, involving certain characterizations, connections with the generalized Linnik distributions and the class of discrete distributions induced by stable laws. We also prove that the Laplace transform of Cauchy-type mixture distributions when normalized by constant terms become as a density functions in terms of distributional conjugate property.     

Competing Frameworks in Planning for the Aged in the Growth Corridors of Melbourne

The Ageing in the Growth Corridors Project was initiated as a partnership between the University of Melbourne and the Department of Health in the Northwest Metropolitan Region of Melbourne, Australia. It involved a research team working with six project officers appointed to stimulate development in relation to an aging population in the sprawling outer metropolitan growth corridors. This article identifies the key lessons learned in terms of project implementation relating to attitudinal and structural barriers to the development of an age-friendly environment in areas of rapid urban growth. The findings illustrate some of the dilemmas raised by competing program conceptions, a dynamic and changing federal/state policy context, and local resource and strategic management constraints. The partnership with the university, nevertheless, provided a point of stability and continuity for the project officers in implementing their mandate.     

Developmental Patterns in Marital Satisfaction: Another Look at Covenant Marriage

This study investigated differences in the trajectory of marital satisfaction in the first 7 years between couples in covenant versus standard marriages. The authors analyzed data on 707 Louisiana marriages from the Marriage Matters Panel Survey of Newlywed Couples, 1998–2004, using multivariate longitudinal growth modeling. When the sample was restricted to couples who remained married over the duration of the study, a marginal benefit of covenant status was found for husbands. This effect was largely accounted for by covenant husbands' more extensive exposure to premarital counseling. The linear decline in marital satisfaction over time that obtained for both husbands and wives was not, however, any different for covenant marriages versus standard marriages. Couples characterized by more traditional attitudes toward gender roles were significantly less satisfied than others. High premarital risk factors, initial uncertainty about marrying the spouse, and the presence of preschool‐age children in the household were all corrosive of marital satisfaction at any given time.     

坚持稳中求进 确保经济平稳增长——2012上半年上海经济形势分析

2012年以来,世界经济复苏减缓,市场需求明显不足,全球产能过剩压力加剧,经济运行风险进一步加大,未来发展前景难以确定。我国经济下行压力也明显加大,未来经济增长面临产能过剩、财政收入下滑、就业压力增大、国际游资冲击等负面影响。上海结构调整取得新的进展,预计全年经济增幅合理上升,但在经济运行中需要特别关注就业形势、小微企业、房地产市场、消费市场、区县经济增长等方面因素。应继续按照"稳增长"与"调结构"相互促进的要求,制定和出台促进经济稳定增长的地方性政策措施,重点是做好中央和上海已有各项政策的落实工作。     

集体耕作制时期农村人口增长分析

通过文献参阅,运用现代经济学和社会学相关理论和方法,探索性地分析集体耕作制时期,农地产权残缺、社会的高度封闭性及平均分配主义的影响和中国农村人口的快速增长。改革开放30年来,影响中国农村人口快速增长的诸因素和人口低生育水平反弹的压力基本消除。面对人口长期负惯性增长的新趋势,中国应及时调整生育政策。     

中国人口变动与经济增长

人口具有生产和消费的双重属性,因此人口变动与经济增长密切相关。考察中国改革开放以来的经济增长态势,以人口为中心系统地分析影响中国改革开放以来经济持续高速增长的主要因素。中国的人口变动主要从四个方面促进了改革开放以来经济持续的高速增长;如果没有其他突发性因素的冲击,单从人口变动因素来看,中国经济还可能再持续增长二十年。     

Fiscal harmonization in view of the Euro adoption: Economic implications for Poland

In this paper, we investigate the ex ante effects of fiscal policy harmonization that might be necessary for the adoption of the common currency on economic growth in Poland using a neoclassical dynamic two-sector general equilibrium model. We study two fiscal policy scenarios. In the first one, we adjust all taxes to German and EU-27 levels, respectively, while in the second one, we change only consumption taxes to German and EU-27 levels. We find that in the first scenario, the current Polish taxes yield the highest rate of growth due to lower capital taxation. However, in the second scenario, German and EU-27 taxes yield the highest rate of growth due to the lower consumption tax on capital-intensive good. From a policy perspective, our results suggest that fiscal policy with lower taxes on capital and capital-intensive goods can generate a higher rate of growth in the long-run. In the case of fiscal harmonization, our findings propose adopting only German or EU-27 consumption tax structure into the Polish tax system.     

The prevalence and composition of asset poverty in Canada: 1999, 2005, and 2012

A household is considered asset poor if its assets (financial assets or net worth, taken separately) are insufficient to maintain well‐being at a low‐income threshold for 3 months. We provide the first national‐level estimates of asset poverty for Canada, using the 1999, 2005, and 2012 cycles of the Survey of Financial Security, and juxtapose these estimates with income poverty. The analysis provides new insight into economic insecurity by showing that asset poverty rates are consistently two to three times higher than income poverty rates. In addition to the prevalence of asset poverty across socio‐demographic groups, we analyzed how the composition of the poor change over time. Age and geography shape the risk for asset poverty in distinct ways. We found that while education appears to play a comparable role in shaping both income poverty and asset poverty, immigration places Canadians at a relatively higher risk of income poverty but not asset poverty. Key Practitioner Message: ? Practitioners ought to consider assets as well as income in assessing economic vulnerability; ? Asset poverty levels are 2–3 times higher than income poverty levels; ? Certain groups (e.g., immigrants) may be income poor but maintain sufficient assets.
