Bioecological Theory, Early Child Development and the Validation of the Population-Level Early Development Instrument

The Early Development Instrument (EDI; Janus and Offord in Canadian Journal of Behavioural Science 39:1–22, 2007) project is a Canadian population-level, longitudinal research project, in which teacher ratings of Kindergarten children’s early development and wellbeing are linked to health and academic achievement variables at the individual level, and to demographic, cultural, and socioeconomic variables at the community level. In this article, we draw from Bronfenbrenner’s bioecological theory of human development to create a coherent theoretical framework for guiding validation research within a population-level approach to child development research in general and for the EDI project in particular. The discussion draws from a range of social and health sciences as well as validity theory. The paper seeks to align complex conceptual, theoretical, methodological, and psychometric considerations, to provide specific design, methodology, and validation recommendations for a population-level approach to studying children’s development and wellbeing, and to discuss the strengths and challenges of this approach.     

The Target Parameter of Adjusted R-Squared in Fixed-Design Experiments

R-squared (R²) and adjusted R-squared (R²_Adj) are sometimes viewed as statistics detached from any target parameter, and sometimes as estimators for the population multiple correlation. The latter interpretation is meaningful only if the explanatory variables are random. This article proposes an alternative perspective for the case where the x’s are fixed. A new parameter is defined, in a similar fashion to the construction of R², but relying on the true parameters rather than their estimates. (The parameter definition includes also the fixed x values.) This parameter is referred to as the “parametric” coefficient of determination, and denoted by ρ²_*. The proposed ρ²_* remains stable when irrelevant variables are removed (or added), unlike the unadjusted R², which always goes up when variables, either relevant or not, are added to the model (and goes down when they are removed). The value of the traditional R²_Adj may go up or down with added (or removed) variables, either relevant or not. It is shown that the unadjusted R² overestimates ρ²_*, while the traditional R²_Adj underestimates it. It is also shown that for simple linear regression the magnitude of the bias of R²_Adj can be as high as the bias of the unadjusted R² (while their signs are opposite). Asymptotic convergence in probability of R²_Adj to ρ²_* is demonstrated. The effects of model parameters on the bias of R² and R²_Adj are characterized analytically and numerically. An alternative bi-adjusted estimator is presented and evaluated.     

Can migration reduce educational attainment? Evidence from Mexico

This paper examines the impact of migration on educational attainment in rural Mexico. Using historical migration rates to instrument for current migration, we find evidence of a significant negative effect of migration on schooling attendance and attainment. IV-censored ordered probits show that living in a migrant household lowers the chances of boys completing junior high school and of boys and girls completing high school. We find that the observed decrease in schooling of 16- to 18-year-olds is accounted for by current migration of boys and increased housework for girls.     

Generalism v Specialism in Human Services Management

The paper focusses upon strategies of adaptation to changing environments adopted by human service organizations. It analyses the influence of the task environment and of the organization's ideology upon the choice of strategies in general, and upon the issue of generalism versus specialism in particular, with respect to two particular human service organizations in Israel — Youth Aliyah and Community Service Organizations. The principal conclusion reached is that specialism is more suitable than generalism for attaining a fit between the organization and its task environment under conditions of rapidly changing, fine-grained environments.     

Public attitudes toward child maltreatment in Israel: Implications for policy

Objective

The public view of the severity of social problems and their perceptions of how effectively they are being addressed have a major impact on public policies and resource allocation. The present study focuses on public attitudes toward child maltreatment. It examines perceptions of child maltreatment as a social problem, and attitudes toward prevention and treatment strategies in cases of child abuse and neglect.

Methods

A survey was conducted among a representative sample of 812 Israeli adults: 688 Jews, and 124 Arabs. Fifty additional Ultra-Orthodox Jews were added for comparisons among Jewish participants.

Results

The participants tend to view violence and alcohol consumption among youth as a more serious problem than parental maltreatment of children. Low-income participants tend to view child maltreatment as a more serious problem than did high-income participants. Jewish participants (except for ultra-Orthodox Jews) view child maltreatment as a significantly more serious problem than did Arabs and Ultra-Orthodox Jews. Most of the participants believe that parents who maltreat their children should be punished, but they should be taught how to refrain from maltreatment, and learn to change their behavior. Many participants believe that the courts do not sufficiently punish parents who maltreat their children. In their assessments of the quality of professional work, the highest evaluations are given to services provided by physicians and social workers, whereas the lowest evaluations are given to judges and police. Most of the participants (70%) believed that social workers play an important role in protecting children.

Conclusions

The survey findings have implications for enhancing public awareness of child maltreatment as well for policy making in the area of child abuse and neglect. The differences in the perceptions of participants based on their religious, cultural and economic background toward child maltreatment should be further studied and addressed in policy and interventions in this area.     

Comparing Immigration Policies: An Overview from the IMPALA Database

This paper introduces a method and preliminary findings from a database that systematically measures the character and stringency of immigration policies. Based on the selection of that data for nine countries between 1999 and 2008, we challenge the idea that any one country is systematically the most or least restrictive toward admissions. The data also reveal trends toward more complex and, often, more restrictive regulation since the 1990s, as well as differential treatment of groups, such as lower requirements for highly skilled than low‐skilled labor migrants. These patterns illustrate the IMPALA data and methods but are also of intrinsic importance to understanding immigration regulation.     

Merging nonprofit organizations: Analysis of a case study

This article presents a case study of merging among nonprofit organizations that provide social and community services. The study sheds light on the dynamics and problems of merging nonprofit organizations, whose espoused ideology focuses on promoting the well-being of their clients. The author describes and analyzes a merger in metropolitan Jerusalem, Israel, and highlights the potential problems that may ultimately undermine its success. This merger is the outcome of an ongoing power and political struggle. The analysis focuses on the organizational ideologies and culture as well as the strategies and structure of the merging organizations. In addition, the author deals with the underlying motives for merging, the driving and restraining forces, and the implications of merging nonprofit community services organizations with other social and human services organizations.
