When traditional measures for material conditions are scarce or unreliable, body mass, height, and weight are complements to standard income and wealth measures. A persistent question in welfare studies is the 19th century’s 2nd and 3rd quarter’s stature diminution, a pattern known as the antebellum paradox. However, the question may not be well stated nor experienced equally by women and non-white male samples. The late 19th century’s political Granger, Greenback, and Populist movements may have affected farmer and non-farmer’s net nutrition. Despite 19th and early 20th century US political movements, farmers had greater BMIs, taller statures, and heavier weights than non-farmers. From the 1870s through 1890s, women’s body mass, height, and weight increased relative to men. Individuals of African or mixed European-African descent had heavier weights and greater BMIs than their taller, European-white counterparts, indicating that the traditional antebellum paradox needs to include women and non-European males and weight measures.

This paper assesses the change over time of within-family inequality in the educational outcomes of Spaniards by measuring the effects of birth order on the number of years of formal education attained in families of different sizes. The analysis is based on data from the 1991 Sociodemographic Survey, adopts the perspective of cohort analysis, and looks at those born in the first six decades of the 20th century. The data reveal that the effects of both the number of siblings and, above all, birth order increased over the cohorts. This means that educational inequalities within Spanish families tended to grow in contrast to inequalities between families in a period of great expansion of the education system. Although the Spanish experience may have differed from that of other developed countries, it fits well within the theoretical framework of conditional dilution of parental resources associated with the number of siblings and birth order.

Deaths in workplace incidents – of both workers and members of the public – normally spark a number of official responses, including coronial inquests. In many instances, however, these investigations have examined the incident in isolation from the wider context of hazards in that industry and are rarely informed by the extensive research literature on health and safety, and death and disaster, at work. In this examination of a tragic theme park disaster in 2016, we demonstrate that applying a wider lens and drawing on the ‘ten pathways model’ not only provides a more compelling explanation of how and why safety measures failed but may also inform more fatality and injury prevention measures. Drawing on James Reasonʼs concept of latent failures, the ten pathways model identifies latent failures that are repeatedly associated with death and disaster in workplaces across different industries. Using the Dreamworld coronial inquest findings and other related source material, this paper finds that at least nine and possibly all ten pattern failures were present in the Thunder River Rapids ride disaster at the Dreamworld theme park and contributed to the deaths of four visitors. In particular, it highlights the corroding effects of poor maintenance, inadequate management systems, and regulatory failure. The paper also raises questions about why theme parks as high-hazard workplaces marked by injuries, deaths, and ‘near misses’ were not subject to more rigorous oversight prior to the event and how regulatory failures might best be addressed.

This article contributes to the debate on regional disparities in living standards in Italy at the time of national unification (1861) by examining the health standards of army conscripts born between 1843 and 1871. Data regarding the conscripts born in 1843-1856 show that 35.4 per cent of youths examined were unfit for military service. Overall, the rejection rate in the peninsular south was similar to that of the northern regions. In the south, however, the share of conscripts rejected for insufficient height was notably higher. It is very likely that the persistent north-south gradient in average height in Italy is related to genetic factors.

The ancient Greek city-states were slave societies, but the institutions of slavery differed across them. The slaves of democratic Athens were foreigners bought as chattels labouring in agriculture, craftsmanship, banking, mining, and domestic services and were often given some limited freedoms and extra pay. On the contrary, the helots, the slaves of oligarchic Sparta, were indigenous of the lands they cultivated for their masters and were treated harshly. The study offers an economic explanation of the different slavery systems. Modelling the slaveholder as a profit maximiser, it attributes the different systems to differences in the probabilities of the slaves running away or revolting, the dependence of output on effort-intensive or care-intensive production technology, which depends on the fertility of the soil and affects whether the slave is treated kindly instead of harshly, and the cost of guarding slaves under different regimes.

Communities urbanize when the net benefits to urbanization exceed rural areas. Body mass, height, and weight are biological welfare measures that reflect the net difference between calories consumed and calories required for work and to withstand the physical environment. Individuals of African-decent had greater BMIs, heavier weights, and shorter statures. Urban farmers had lower BMIs, shorter statures, and lower weight than rural farmers. Over the late 19th and early 20th centuries, urban and rural BMIs, height, and weight were constant, and rural farmers had greater BMIs, taller statures, and heavier weights than urban farmers and workers in other occupations.

In this article, we examine the effect of workforce ageing on company productivity, using an analysis based on Korean firms. We found that an increase in the ratio of workers aged over 50 years to total workers had a negative effect on value added per worker, which was consistent with the findings of most previous studies based on European data. However, the results of the analysis, including various classifications such as size, industry and several financial conditions, revealed that an increase in the ratio of older workers had positive effects on value added per worker in large manufacturing firms under risky or growing conditions. As the productivity of older workers may vary, future research may determine under what conditions – size, industry, region and financial conditions – older workers contribute positively to productivity. Firms with financial troubles or those planning to downsize should be cautious about laying off older workers as an approach to improving organisational performance because these workers contribute positively to productivity under certain conditions.

Historical literacy in Spain is characterised by enormous regional disparities and important differences by sex. This paper addresses these issues, focusing initially on the 1887 census returns and also making use of local empirical data and of in-depth interviews of elderly informants. The goal is to propose an interpretation of historical patterns of literacy based, to a large extent, on the existence of important differences in the perceived value of literacy and education, very high in some regions and very low in others. The author argues that these cleavages go beyond the importance of economic structures, have deep historical roots and continue to be present in contemporary Spain despite the substantial growth in educational attainment taking place during this past century.

Challenging current ideas in mainstream scholarship on differences between female labour force participation in southern and north-western Europe and their impact on economic development, this article shows that in Portugal, neither marriage nor widowhood prevented women from participating in the labour market of mid-eighteenth-century. Our research demonstrates that marriage provided women with the resources they needed to work in various capacities in all economic sectors.

This article also argues that single Portuguese women had an incentive to work and did so mostly as wage earners. Finally, the comparison of our dataset on female occupations from tax records with other European cases calls for a revision of the literature and the development of a more nuanced picture of the north-south divide.

This paper deals with the evolution of wages in the construction offices of Segovia, one of the most important Castilian and Spanish manufacturing towns, between 1571 and 1807. Part two deals with the nominal wages earned by the building officials and labourers of the city and part three presents the Segovian prices index between 1571 and 1807. Finally, part four analyses the evolution of the real wages earned in the construction offices of the town. Segovian real wages evolved in line with the local economy; after peaking in the first quarter of the 17th century, they experienced a continuous decline, so in 1807 the real wages of Segovian building officials and labourers were 50 per cent of those of the first quarter of the 17th century.

Trends in human welfare in Brazil have remained shrouded by a dearth of historical evidence. Although quantitative scholars have revealed the efficacy of the First Republic (1889–1930) in fomenting economic progress, the extent to which Brazil's early economic growth fostered improvements in health remains unclear. This paper fills this void in scholarship by relying on hitherto untapped archival sources with data on human stature—a reliable metric for health and nutritional status. My analysis centres heavily on a large (n ≈ 16,000), geographically-comprehensive series compiled from military inscription files, supplemented by an ancillary dataset drawn from passport records (n ≈ 6,000). I document inferior heights in the North and Northeast that predated the advent of industrialisation. At the national level, my findings reveal an increase in stature of over 2.5 cm between soldiers born in the 1880s and those born in the 1910s. In the South and Southeast, I argue that increased real income and public-health interventions explain the earlier upward trend in heights, while rural sanitary reforms were most important in the North and Northeast, where heights remained stagnant until the 1910 decade and diseases such as hookworm and malaria were most rampant.

Average stature reflects cumulative net nutrition and health during economic development. This study introduces a difference-in-decompositions approach to show that although 19th century African-American cumulative net nutrition was comparable to working class whites, it was made worse-off with the transition to free-labor. Average stature reflects net nutrition over the life-course, and adult blacks born under bound-labor had greater age related statures loss than blacks under free-labor. Agricultural worker's net nutrition was better than workers in other occupations and was better-off under free-labor and industrialization. Within-group stature variation was greater than across-group variation, and white within-group stature variation associated with socioeconomic status was greater than African-Americans.

This paper attempts to establish a debate between alternative views of living standards in Spanish America during the viceregal period. Since 2009, a growing literature has shared a «common language» based on a similar, though not identical, methodology. As never before, this «new generation» of studies is built upon long series of quantitative data and international comparisons of nominal wages and prices which, in some cases, cover the whole Early Modern Era. Part of this literature also complements the examination of economic welfare using height as an indicator of biological welfare. Inequality is also quantitatively approached in one of the works discussed. In spite of significant similarities, some methodological differences lead to contrasting results. For the sake of simplicity, the relevant literature is divided into two views: «pessimism» and «optimism». It is my contention that the latter is more consistent with the available evidence.

Introduction: Cardiovascular disease remains the commonest health problem in developed countries, and residual risk after implementing all current therapies is still high. The use of marine omega-3 fatty acids (DHA and EPA) has been recommended to reduce cardiovascular risk by multiple mechanisms. Objectives: To update the current evidence on the influence of omega-3 on the rate of cardiovascular events. Review Methods: We used the MEDLINE and EMBASE databases to identify clinical trials and randomized controlled trials of omega-3 fatty acids (with quantified quantities) either in capsules or in dietary intake, compared to placebo or usual diet, equal to or longer than 6 months, and written in English. The primary outcome was a cardiovascular event of any kind and secondary outcomes were all-cause mortality, cardiac death and coronary events. We used RevMan 5·1 (Mantel-Haenszel method). Heterogeneity was assessed by the I2 and Chi2 tests. We included 21 of the 452 pre-selected studies. Results: We found an overall decrease of risk of suffering a cardiovascular event of any kind of 10 % (OR 0·90; [0·85–0·96], p = 0·001), a 9 % decrease of risk of cardiac death (OR 0·91; [0·83–0·99]; p = 0·03), a decrease of coronary events (fatal and non-fatal) of 18 % (OR 0·82; [0·75–0·90]; p < 1 × 10− 4), and a trend to lower total mortality (5 % reduction of risk; OR 0·95; [0·89–1·02]; p = 0·15. Most of the studies analyzed included persons with high cardiovascular risk. Conclusions: marine omega-3 fatty acids are effective in preventing cardiovascular events, cardiac death and coronary events, especially in persons with high cardiovascular risk.

The Semantic Web drives toward the use of the Web for interacting with logically interconnected data. Through knowledge models such as Resource Description Framework (RDF), the Semantic Web provides a unifying representation of richly structured data. Adding logic to the Web implies the use of rules to make inferences, choose courses of action, and answer questions. This logic must be powerful enough to describe complex properties of objects but not so powerful that agents can be tricked by being asked to consider a paradox. The Web has several characteristics that can lead to problems when existing logics are used, in particular, the inconsistencies that inevitably arise due to the openness of the Web, where anyone can assert anything. N3Logic is a logic that allows rules to be expressed in a Web environment. It extends RDF with syntax for nested graphs and quantified variables and with predicates for implication and accessing resources on the Web, and functions including cryptographic, string, math. The main goal of N3Logic is to be a minimal extension to the RDF data model such that the same language can be used for logic and data. In this paper, we describe N3Logic and illustrate through examples why it is an appropriate logic for the Web.

Historical studies show that the average height of Western European children began its secular growth in 1850 only after a period of decline and stagnation which had started around 1750. We argue that the initial downturn in heights is related to the demographic transition, and show that an extension of the neoclassical model of economic growth can explain the observed phenomena. We test whether the predictions of the model hold for a cross-section of contemporary countries, and we find that stature is indeed negatively associated with income per capita and fertility for countries with an income per capita below a given threshold. As a final exercise, we ask whether these cross-country estimates explain the improvement in children's height observed in the last hundred and fifty years.

Este artículo estudia dos temas referidos a los orígenes de la incorporación de España a la modernidad desde la perspective de la historia del consume y la culture material. Xomando como ejemplo el caso de Madrid, en primer lugar se indaga la adopción por parte de sus clases medias y altas de lo que se conoce como cultura de consume moderno. En segundo lugar se analiza en qué medida esa cultura contribuyó al moldeado de las identidades politicas que propiciaron la movilización en torno al ideal revolucionario del liberalismo. Las conclusiones extraidas se fundamentan en el estudio de una muestra de 766 inventarios post mortem de families establecidas en Madrid entre 1750 y 1880.
