The psychological consequences of midlife men's social comparisons with their young adult sons

I examine how midlife men (N= 542) compare their work and family lives with those of their young adult sons, and how these comparisons affect the fathers’ self‐evaluations. Analyses are based on quantitative and qualitative data from the Wisconsin Longitudinal Study. Fathers who rate their work lives as more successful than their sons’ have elevated self‐esteem only when they also report being very close with their children. Open‐ended interviews reveal that men derive pride from financially supporting their families, yet normative and economic constraints of the “good provider” role prevented them from pursuing their own career aspirations and from maintaining close parent‐child ties. Intergenerational social comparisons highlight the distinctive work and family constraints felt by the midlife fathers.     

A Cross-Cultural Study of Values Emphasized in Education

The study involves an analytical investigation of the relative importance of eighteen values in the education of young people in nine countries. While the difficulties in obtaining the data led to numerous limitations, the indications developed in the analysis provide an interesting comparison of the similarities and differences in a number of very different cultures. The study also demonstrates an analytical direction that could provide a useful method for comparing different cultures. This revised version was published online in August 2006 with corrections to the Cover Date.     

IDENTIFYING TREATMENT EFFECTS IN MULTI-CHANNEL MEASUREMENTS IN ELECTROENCEPHALOGRAPHIC STUDIES: MULTIVARIATE PERMUTATION TESTS AND MULTIPLE COMPARISONS

A versatile procedure is described comprising an application of statistical techniques to the analysis of the large, multi‐dimensional data arrays produced by electroencephalographic (EEG) measurements of human brain function. Previous analytical methods have been unable to identify objectively the precise times at which statistically significant experimental effects occur, owing to the large number of variables (electrodes) and small number of subjects, or have been restricted to two‐treatment experimental designs. Many time‐points are sampled in each experimental trial, making adjustment for multiple comparisons mandatory. Given the typically large number of comparisons and the clear dependence structure among time‐points, simple Bonferroni‐type adjustments are far too conservative. A three‐step approach is proposed: (i) summing univariate statistics across variables; (ii) using permutation tests for treatment effects at each time‐point; and (iii) adjusting for multiple comparisons using permutation distributions to control family‐wise error across the whole set of time‐points. Our approach provides an exact test of the individual hypotheses while asymptotically controlling family‐wise error in the strong sense, and can provide tests of interaction and main effects in factorial designs. An application to two experimental data sets from EEG studies is described, but the approach has application to the analysis of spatio‐temporal multivariate data gathered in many other contexts.     

Strategies for inference robustness in focused modelling

Advances in computation mean that it is now possible to fit a wide range of complex models to data, but there remains the problem of selecting a model on which to base reported inferences. Following an early suggestion of Box & Tiao, it seems reasonable to seek 'inference robustness' in reported models, so that alternative assumptions that are reasonably well supported would not lead to substantially different conclusions. We propose a four-stage modelling strategy in which we iteratively assess and elaborate an initial model, measure the support for each of the resulting family of models, assess the influence of adopting alternative models on the conclusions of primary interest, and identify whether an approximate model can be reported. The influence-support plot is then introduced as a tool to aid model comparison. The strategy is semi-formal, in that it could be embedded in a decision-theoretic framework but requires substantive input for any specific application. The one restriction of the strategy is that the quantity of interest, or 'focus', must retain its interpretation across all candidate models. It is, therefore, applicable to analyses whose goal is prediction, or where a set of common model parameters are of interest and candidate models make alternative distributional assumptions. The ideas are illustrated by two examples. Technical issues include the calibration of the Kullback-Leibler divergence between marginal distributions, and the use of alternative measures of support for the range of models fitted.     

A direct approach to false discovery rates

Summary. Multiple-hypothesis testing involves guarding against much more complicated errors than single-hypothesis testing. Whereas we typically control the type I error rate for a single-hypothesis test, a compound error rate is controlled for multiple-hypothesis tests. For example, controlling the false discovery rate FDR traditionally involves intricate sequential p -value rejection methods based on the observed data. Whereas a sequential p -value method fixes the error rate and estimates its corresponding rejection region, we propose the opposite approach—we fix the rejection region and then estimate its corresponding error rate. This new approach offers increased applicability, accuracy and power. We apply the methodology to both the positive false discovery rate pFDR and FDR, and provide evidence for its benefits. It is shown that pFDR is probably the quantity of interest over FDR. Also discussed is the calculation of the q -value, the pFDR analogue of the p -value, which eliminates the need to set the error rate beforehand as is traditionally done. Some simple numerical examples are presented that show that this new approach can yield an increase of over eight times in power compared with the Benjamini–Hochberg FDR method.

Multiple comparisons with a control in repeated measures incomplete block designs using R-estimators

New multiple comparison with a control (MCC) procedures are developed in repeated measures incomplete block design settings based on R-estimates. It is assumed that the errors within each subject are exchangeable random variables. The R-estimators of the treatment effects are obtained by minimizing a sum of Jaeckel (1972)-type dispersion functions. Based on the R-estimators, Dunnett-type multiple comparison procedures are developed for comparing test-treatments with a control-treatment. Under exchangeable errors, it is demonstrated that for Cox-type designs, the new procedures are more efficient than the existing nonparametric procedures. The new MCC procedures are applied to a data set in a clinical trial which consists of patients with reversible obstructive pulmonary disease.     

The Local and the National in Community Care: Exploring Policy and Politics in Finland and Britain

International literature on community care tends to focus on the national level of welfare institutions and policies. However, community care is largely a locally tailored service and this paper makes a case for local comparisons of community care policies. Using local case studies from Finland and Britain, the paper argues that focusing on the local level contributes to the comparative study of community care in two ways. First, local comparisons highlight the often distinctively local nature of community care policies and thereby add to our understanding of community care. Second, local comparisons extend existing cross‐country explanations of community care by showing that community care is largely shaped by local politics, together with indirect structuring by national contexts. As such, the local case studies highlight the importance of the relationship between policy and politics, which has often been neglected in comparative research.     

Alcohol-Related Mortality in 15 European Countries in the Postwar Period

The aim of this paper isto assess postwar differences and trends inalcohol-related mortality in the currentEuropean Union (minus Luxembourg plus Norway)on the basis of liver cirrhosis mortality anddeaths with explicit mention of alcohol,primarily alcohol dependence, alcohol psychosisand alcohol poisoning (AAA). The questionof the extent to which these indicators arecomparable across Western European countries isalso addressed. A marked north-south gradientwas found for cirrhosis mortality, with thehighest rates revealed in Southern Europe andthe lowest in Northern Europe. However, thisgradient weakened with the passage of time andthe initially quite substantial regionaldifferences declined during the latter part ofthe study period. Explicitly alcohol-relatedmortality (AAA), on the other hand, showed areverse cross-national pattern with the highestrates in the north and the lowest in the south.A positive cross-national relationship wasobserved between cirrhosis and per capitaconsumption but this match was not improved bycombining cirrhosis with explicitlyalcohol-related causes. Nevertheless, withinSouthern, Central and Northern Europeancountries the relationship between per capitaconsumption and AAA-mortality was positive. Itis concluded that cirrhosis mortality is usefulfor making rough national comparisons in aWestern European context whereas the validityof explicitly alcohol-related mortality isquestionable. Cultural differences in recordingpractices and drinking patterns are discussedas possible determinants of geographicaldifferences in AAA-mortality.     

Visibility and 'child view' in the assessment process of social work: cross-national comparisons

In Western societies, national and international legislation and agreements are giving increasing support to the principle that children must be regarded as subjects, with the right to be in focus and to express their own views in the assessment process of social work. The empirical data in the present study, collected from more than 700 social workers through open-ended questions, and generated in a cross-national vignette study of child protection cases in Denmark, Germany, Sweden, Britain and Texas, are analysed within a conceptual framework of 'child visibility' and 'child view'. The results reveal a number of systematic patterns within and between the areas under study. The child is visible to different extents but also with varying emphasis across the countries. The possibility for the views of the child to be included in assessment processes differs due to the age of the child and across the countries.
