Testing hypotheses for the growth curve model when the data are incomplete

Kleinbaum (1973) developed a generalized growth curve model for analyzing incomplete longitudinal data. In this paper the small sample properties of several related test statistics are investigated via Monte Carlo techniques. The covariance matrix is estimated by each of three non-iterative methods. The null and non-null distributions of these test statistics are examined.

The impact of internal communication on strategic and economic effects in Serbian companies

This paper presents the research results in relation to examining and defining dependences and the impact of internal communication on certain strategic and economic business effects. Serbian companies were the focus of this research. The data were collected by polling 100 managers from 100 companies. Afterwards, multivariate regression and correlation was carried out in the aim of the final determination of requested dependences. This research confirmed a strong positive relation between internal communication and strategic and economic business effects.     

Family structure and the economic wellbeing of children in youth and adulthood

An extensive literature on the relationship between family structure and children’s outcomes consistently shows that living with a single parent is associated with negative outcomes. Few US studies, however, examine how a child’s family structure affects outcomes for the child once he/she reaches adulthood. We directly examine, using the Panel Study of Income Dynamics, whether family structure during childhood is related to the child’s economic wellbeing both during childhood as well as during adulthood. We find that living with a single parent is associated with the level of family resources available during childhood. This finding persists even when we remove time invariant factors within families. We also show that family structure is related to the child’s education, marital status, and adult family income. Once we control for the child’s demography and economic wellbeing in childhood, however, the associations into adulthood become trivial in size and statistically insignificant, suggesting that the relationship between family structure and children’s long-term, economic outcomes is due in large part to the relationship between family structure and economic wellbeing in childhood.

Social networks and the organisation of big business groups in post New Economic Policy (NEP) era in the 1990s in Malaysia

Personal ties are generally regarded as important to big business growth in Malaysia, particularly after the New Economic Policy (NEP) in the 1990s. Common types are informal ones established between multi-ethnic big business people and Malay key state and political leaders. Other types of ties, company directorship links and informal ties, are seldom studied especially those between the business people and former state bureaucrats and corporate professionals. Thus, by conceptualising the directorship links and informal personal ties as social networks, the author conducted a sociological analysis of some intra- and inter-ethnic directorship links and ties established by four prominent big businessmen after the NEP in the 1990s. This article reports the main finding on the links and ties becoming a common organisational mechanism of business groups owned and controlled by the businessmen, besides providing access to the state. Therefore, another understanding of inter- and intra-ethnic personal ties in big business growth, especially after the NEP is achieved.     

The Double Challenge of Market and Social Incorporation: Progress and Bottlenecks in Latin America

Has the past decade of sustained economic growth and political transformations reversed Latin America's historical failure to secure market and social incorporation? To address this question this article draws on the experiences of Bolivia, Brazil, Chile, Peru and Uruguay by distinguishing between short‐term outcomes – which may depend on benign international conditions – and policy changes, which are more important for long‐term performance. It highlights the overall success of both Brazil and Uruguay and shows that the other countries have made more progress in terms of social than market incorporation.     

Changes in the labour market and health inequalities during the years of the recent economic downturn in Italy

There is widespread concern that episodes of unemployment and unstable working conditions adversely affect health. We add to the debate by focusing on the relationship between work trajectory and the self-reported health of Italian men and women during the present economic downturn. Relying on Italian data in the EU-SILC project (from 2007 to 2010), our sample includes all individuals aged 30 to 60 in 2010, and uses multivariate binomial regression models for preliminary analyses and the Structural Equations modelling (SEM) to observe the cumulative effects of health status according to different job trajectories. Our main findings show similar pictures for men and women. Individuals who are unemployed, ejected or in precarious occupational positions have a higher risk of worsening their health status during these years.
