The resort to divorce in England and Wales, 1858–1957

This paper consists of a statistical analysis of the increasing resort to divorce in England and Wales over the past hundred years. In view of the social, financial and procedural barriers surrounding the Divorce Court over most of the period it is impossible to regard the spread of divorce as an index of increasing marital breakdown. It indicates merely the greater ability and willingness of estranged couples to take advantage of the legal machinery for bringing their marriages to a formal end.

The analysis of published data shows that since 1857, the rate of petitioning per 10,000 married couples (of whom the wives were 15–49 years of age) has risen from 0.83 to 37.98. Various factors have been responsible for this fifty-foild increase: it seems that a five-fold rise was due specifically to the lowering of formal barriers (which made divorce more accessible to the poor and to women petitioners), while the remaining tenfold increase was brought about by the growing acceptance by society and by discordant couples, of divorce as an appropriate end to a broken marriage. This change in public opinion can be seen not only in the slow yet persistent rise in the rate of petitioning over all but the last few years, but also in the long-term effects of the two world wars.

Divorces since 1921 have been allocated to the various marriage cohorts involved so as to estimate the proportion of each cohort divorced by successive marriage anniversaries. This procedure has shown that the recent war had its greaters disruptive impact on the “hastliy contracted” marriages of the early war years; the impact on these cohorts was, however, only slightly in excess of that exerted on the immediately preceding cohorts married in the later 1930's. In fact the war took its toll of all cohorts back to 1921.

As complement to this study of trends the position near the beginning and near the end of the whole period was investigated by analysing a special extraction of statistics relating to all the 1871 petitions and to a sample of those of 1951. The study of couples involved in divorce in these two years, illustrates its extension in the intervening period to most sectors of the married population. From a tiny group of predominantly well-to-do and frequently childless couples in 1871, the divorce population by 1951 appeared to have become very nearly a cross-section of all married couples, at least in respect to occupational structure and family size. To some extent, the close similarity between the divorcing and the still married couples in 1951 was a temporary phenomenon, due to the entry into the divorce courts in that year of an unuually large number of poor petitioners using the new legal aid provisions introduced in 1950. Nevertheless, there is good reasong to believe that this factor has led to only slight over-emphasis of the long-term trend for the poor and those with families to take an increasing share in divorce petitioning.

So far as the mid-twentieth century position is concerned cohort analysis shows that, at least in the early years of matrimony, the couples married since 1945 have petitioned for divorce less than their immediate elders in the wartime or just pre-war cohorts. While the post-war marriages have not run their full course through the most divorce-prone years, this finding suggests that the rate of petitioning is not likely to go on increasing in the future nearly so rapidly or so persistently as it has done in the past. It seems possible that the rate may be stabilized in the next few years at approximately its present level, i.e. within the range of 5%–10% of each marriage cohort. If this should occur, it would probably mean that divorce in England and Wales had found its own level, and that virtually all those requiring to terminate marriage in the existing context of social circumstances were no longer prevented by extraneous barriers from using the appropriate legal procedures.     

Fourth order rotatability

Fourth order rotatable designs are discussed. A general k, design moment inequality is given. The variance function for two-factor designs is derived, and plotted for a specific design. A minimum point set requirement for two-factor designs is established, thus enabling one to form an infinity of such designs. Some difficulties in obtaining deLigns for k>2 are described. Some questions are posed for future work.     

Assessing prior information for designed experiments

We examine, via a Bayesian analysis, in a general experimental situation, whether if is worthwhile to obtain additional prior information before performing an experiment. Examples illustrate the application of the techniques developed.     

Inspection errors in link sampling

Results of an investigation into the sensitivity to two types of inspection error of link sampling procedures described by Harischchandra and Srivenkataramana are reported. Relevant compound distributions are derived. Some comparisons with results obtained in a similar investigation for standard double sampling are also given.     

Dorfman-sterrett screening (group testing) schemes and the effects of faulty inspection

The Dorfman screening procedure is based on first testing a group of items as a whole, proceeding to individual testing only if the group-test indicates existence of at least one nonconforming item. A modification suggested by Sterrett allows for reintroduct-ion of group testing of all items, not yet tested individually, when an item is classified as nonconforming by an individual test. Effects of faulty test inspection on the properties of the modified procedures are studied.     

Conventional and expanded adverse childhood experiences (ACEs) and maternal functioning among low-income Black mothers

A paucity of research has examined the individual and cumulative effects of conventional and expanded adverse childhood experiences (ACEs) on maternal functioning, especially among low-income Black mothers. Using self-report data from a subsample of Black mothers (N = 157) who participated in a larger study to evaluate the effectiveness of an urban public prekindergarten program in the mid-Atlantic region of the United States, we examined the prevalence of ACEs and the individual and cumulative effects of conventional (i.e., family trauma and dysfunction) and expanded (i.e., community stressors) ACEs on depression and health among low-income Black mothers. Findings indicated that Black mothers had more exposure to expanded than conventional ACEs. Hierarchical regression analyses revealed that experience of physical neglect was significantly associated with depression and physical abuse with compromised health, and perceived experience of racism was a predictor of depression and compromised health. More conventional and expanded ACEs were associated with clinical levels of depression and compromised health. Findings highlight the need for more research related to the impact of ACEs, especially expanded ACEs, on mental and behavioural health outcomes. Additionally, our findings indicate the need for more trauma-informed care to reduce and address the impact of individual and community-level adversities on low-income Black mothers.     

The European Union's migration management aid: Developing democracies or supporting authoritarianism?

The European Union and its member states have invested billions of euros in migration management programs that purport to promote “good migration governance” around the world. But what is the impact of migration management aid on governance outside of the EU? In this article, we theorise the impact of migration management aid on governance in recipient countries by analysing the key policy areas of intervention. To do so, we focus on the effects of the European Union Emergency Trust Fund for Africa and draw on data collected from policy and government documents, in addition to secondary literature, to understand how migration management aid negatively impacts institutions of governance in recipient countries. While migration management aid may build the capacity of states to monitor borders and prevent irregular migration, we argue that this fails to account for negative externalities including human rights abuses and increased surveillance for migrants and citizens alike.
