Does Size Really Matter? On the Relationship between Immigrant Group Size and Anti‐Immigrant Prejudice

Group threat theory understands prejudice as a manifestation of the threat, either actual or assumed, that minority groups pose to majority groups. This theory is often operationalized by analyzing the impact of group size on anti‐immigrant prejudice. We test this hypothesis with a new dataset documenting 487 effects of group size on prejudice provided in 55 studies. More than half of these results show no relationship and the remainder shows both positive and negative relationships. Three explanations for this divergence are that there are (1) differences in the measurement of prejudice and immigrant group size across studies; (2) differences in the model through which size is hypothesized to lead to prejudice; and (3) differences in the geographic unit of analysis at which these relationships have been considered. Our analyses support the measurement explanation: results vary across studies because they reflect different measures of group size and prejudice.     

Are the roads red? Comments on “Size Matters”

Models are neither true nor false. Models are sometimes useful and sometimes misleading. The suggestion that “Size Matters” implicitly accepts the truthfulness goal and deploys a truthfulness metric for measuring the distance between the data and the model. With this way of thinking, we would be led decisively to “reject” a road map that has freeways colored red.     

A Multi‐method Approach to the Study of School Class Size Differences

This paper describes a multi‐method approach to data collection used in a large‐scale seven‐year longitudinal study of the effect of class size differences on classroom processes. There were five main types of process and the paper concentrates on the results from one of these: teaching interactions with pupils. It was felt that integration of results from quantitative and qualitative methods would help reconcile inconsistencies and limitations in previous research on this topic. Quantitative information was collected from systematic classroom observations and teacher completed time estimates to address relationships between class size and teacher time allocation, and teacher and pupil behaviour in class. But we also wanted a more qualitative assessment of relationships between class size and teaching through the use of methods that captured practitioners’ experiences, and through detailed case studies. Examples of integrated results from these four methods are given, along with some reflections on lessons learned.     

The significance of the significance test controversy: comments on ‘Size Matters’

The concerns expressed and issues raised by Zialik and McCloskey concerning the use of tests of statistical inference have also been raised in sociology and psychology. This paper examines the similarities and differences between the way that the significance test controversy has been discussed in the wider social sciences and Zialik and McCloskey's discussion of the implications for economics. The issues are similar in that different effects of over-reliance on the rejection of the null hypothesis are identified. These include mistakes and errors in statistical inference, the lack of the use of diagnostic statistics to qualify and guide statistical inference, and the broader impact on the field of accumulation of type II errors and lack of innovation in the field. There is considerable agreement on these points between sociologists, psychologists and economists who are concerned about these issues. However, there are also important differences that are discussed in this response. In particular, in the other social sciences the significance test controversy has broadened out and has been linked firstly to more discussions of the limitations of experimental and correlational designs and to a broader critique of positivism and scientism in the social sciences. Without this broader context the significance of the significance test controversy is understood in a more restricted way as a technical problem with widespread effects whereas in the social sciences it has been understood as symptomatic of broader disciplinary commitments in theory and purpose.     

Doubling Up or Moving Out? The Effect of International Labor Migration on Household Size

We use household panel data from Tajikistan to explore the change in living arrangements as a response to income shifts related to international labour migration. In addition, we analyse the interaction between the effect of idiosyncratic income increase resulting from a completed migration episode, and the effect of an aggregate shock – the global financial crisis – and show how different households adjust their household size during times of financial hardship. The empirical evidence indicates that while current migration is associated with an increase in household size, a completed migration episode two years before the interview was followed by family members moving out. At the same time, our empirical analysis demonstrates that migrant families doubled up in response to a financial crisis to the same extent as non-migrant families, which suggests that labour migration in Tajikistan does not insure against economic shocks in the long run.     

The Size of the Irregular Migrant Population in the European Union – Counting the Uncountable?

It is difficult to estimate the size of the irregular migrant population in a specific city or country, and even more difficult to arrive at estimates at the European level. A review of past attempts at European-level estimates reveals that they rely on rough and outdated rules-of-thumb. In this paper, we present our own European level estimates for 2002, 2005, and 2008. We aggregate country-specific information, aiming at approximate comparability by consistent use of minimum and maximum estimates and by adjusting for obvious differences in definition and timescale. While the aggregated estimates are not considered highly reliable, they do -- for the first time -- provide transparency. The provision of more systematic medium quality estimates is shown to be the most promising way for improvement. The presented estimate indicates a minimum of 1.9 million and a maximum of 3.8 million irregular foreign residents in the 27 member states of the European Union (2008). Unlike rules-of-thumb, the aggregated EU estimates indicate a decline in the number of irregular foreign residents between 2002 and 2008. This decline has been influenced by the EU enlargement and legalisation programmes.     

What Determines the Size of the Nonprofit Sector?: A Cross-Country Analysis of the Government Failure Theory

This article is an empirical examination of the government failure theory using a cross-country data set. The government failure theory is represented in the major existing literature as providing a sound explanatory basis for an interesting characteristic of the nonprofit sector, that is, there is a large variability in nonprofit sector size from one place to another. Salamon et al. (Social origins of civil society: An overview, Working Papers of the Johns Hopkins Comparative Nonprofit Sector Project, 2000) examined this theory using the Johns Hopkins Comparative Nonprofit Sector Project (CNP) data set, and consequently rejected the government failure theory. However, by applying the panel analysis approach to the CNP data set, this article shows that the government failure theory should not have been so easily rejected.     

Does one Size Fit All?—Linking Parenting With Adolescent Substance Use and Adolescent Temperament

Using longitudinal Swedish data from 1,373 early‐adolescent youths, this study aims to answer the question of whether the previously established protective function of parental knowledge and its sources—adolescent disclosure, parental solicitation, and parental control—on substance use among early‐adolescents is moderated by the adolescent's temperament. Adolescent temperament moderated several links between parental knowledge and its sources and adolescent substance use. The most pronounced moderating results were found for those adolescents with fearless, socially detached and thrill‐seeking tendencies. For these “detached thrill‐seekers”, bidirectional links between adolescent disclosure and substance use, and negative links between parental solicitation and substance use were found. We recommend, therefore, that adolescent temperament is considered when designing parenting programs.     

Mexican Americans’ Lucky Few and Baby Boom Cohorts: How Is Relative Cohort Size Related to the Likelihood of Being Out-of-Poverty?

Generational cohorts influence individuals’ economic life chances. Retrospective analysis has found that the “Lucky Few” generation had better life chances than previous generations. We focus on Mexican Americans in the United States and offer a prospective analysis to explore how relative cohort size plays a role in the odds of their being out-of-poverty. Using Public Use Microdata Sample files from 1990, 2000, and 2010, we test the hypothesis by comparing Early Baby Boom (those born between 1946 and 1955) and Late Baby Boom (those born between 1956 and 1965) cohorts to the Lucky Few (born between 1936 and 1945) cohort. Models predicting the odds of being out-of-poverty during the peak wage-earning years indicate that belonging to the Lucky Few cohort affords Mexican Americans no economic advantage. Our findings demonstrate that the relative cohort size hypothesis may not always be generalized to Mexican American minority samples.     

Who “Fills in” for Siblings and How? A Multilevel Analysis of Personal Network Composition and Its Relationship to Sibling Size1

In the midst of widespread fertility decline, I examine the relationship between sibling number and support network composition using multilevel regression on data from 25 countries. A fundamental structural effect of having fewer siblings is that individuals have a smaller pool of available close‐kin alters with whom to construct support networks. Consequently, networks of people with fewer siblings should be composed of different sorts of relations. Results confirm that such compositional adjustment occurs in systematic ways. Compared to those with three or more siblings, adults with none to two siblings (as separate categories) are more likely to expect support from parents, extended kin, and close friends but not more likely to do so from spouses/partners and children. Single children are also more likely to include neighbors and have smaller‐sized and/or impersonal networks. These findings contradict the primacy of familial ties in social support networks. Moreover, adjustment of support networks towards nonsibling ties occurs in culturally expected ways. Those with fewer siblings are generally only more likely to turn to ties for the types of support typically associated with those relations—parents for instrumental and financial support and friends for emotional support. Single children, however, also violate institutionalized expectations of social support by turning to ties for a wider range of social support. The results suggest that continuing declines in fertility could bring about both reinforcement and rearticulation of the sociocultural framing of close personal relationships. Moreover, consistent with recent research, the results show that personal networks are influenced more by individual‐level than country‐level factors.
