The National Archives of Tanzania (Idara ya Kumbukumbu za Taifa la Tanzania) were established on 28 August 1965. Since this date energies have been directed toward building an efficient archival service: better storage facilities have been acquired, trained Tanzanian personnel have been hired, and there is now seating space for ten researchers. The most significant development from the historian's point of view has been the recent organization of the German records into a concise and convenient index catalogue.

In June 1967 the West German Government Technical Aid Program sent Mr. Peter Geissler, an Archivinspektor at Hessiches Staatsarchiv, Marburg, on a two-year project to reorganize the German records. Mr. Geissler is already familiar to historians of the American Revolution for his research on the Hessian troop records at Marburg. In Deutsch-Ostafrika the old German Registry System (renewed in 1902 and in effect until 1916) had been utilized in numbering the various files. A still extant two-volume Registry lists all the documents in existence before the First World War, but many of these have since been lost, eaten by white ants, stolen, or destroyed. It is evident that only a few records concerning district political administration have survived, while land, legal, mission, public works, and education files are among the most complete. The files have been divided into two main groupings: (1) the old German Registry and other German Government Administration (G 1 - G 65); and (2) Private Archives (G 66 - G 86). Each file card contains both the new “G” number and the old German Registry designation. In addition Mr. Geissler has performed a painstaking task in listing on each card some of the outstanding names, places, etc. mentioned in the particular file.

I had originally planned to focus on some of the more important aspects of race and ethnicity in Africa south of the Sahara, with particular reference to tensions and conflicts operative within the emergent social and political systems. I soon the realized, however, that the subject was far too complex for brief presentation, at least the kind of brevity ritualistically mandatory on this ceremonial occasion. I decided, consequently, to concentrate on one aspect of the complex cited, namely, the problems and prospects of the white man, particularly as settler, in the revolutionary Africa of today. Obviously, this grand theme, given all the imponderables involved, can only be touched upon lightly and is not easily susceptible to “scientific” treatment. I shall do my best, however, in handling this value-laden problem to observe the procedures and the folkways of objective analysis.

The dominant focus on rheumatic aetiology of mitral regurgitation (MR) often overshadows other causes. This challenges optimal management when the aetiology is non-rheumatic, as exemplified below in an 8-year-old girl, hailing from Uganda, who was diagnosed and managed as rheumatic MR with unusually elevated and persistent systemic inflammatory state with chronic renal dysfunction disproportionate to her cardiac status. Further workup led towards the possibility of early onset systemic lupus erythematosus (SLE). The valvular involvement in SLE closely resembles rheumatic heart disease (RHD). A high level of clinical suspicion is essential for diagnosing childhood-onset SLE. Coexistence of RHD and SLE is extremely rare and has significant implications for management.

An adverse in utero experience negatively impacts perinatal growth in livestock. Maternal heat stress (HS) during gestation reduces placental growth and function. This progressive placental insufficiency ultimately leads to fetal growth restriction (FGR). Studies in chronically catheterized fetal sheep have shown that FGR fetuses exhibit hypoxemia, hypoglycemia, and lower anabolic hormone concentrations. Under hypoxic stress and nutrient deficiency, fetuses prioritize basal metabolic requirements over tissue accretion to support survival. Skeletal muscle is particularly vulnerable to HS-induced placental insufficiency due to its high energy demands and large contribution to total body mass. In FGR fetuses, skeletal muscle growth is reduced, evidenced by smaller myofiber size and mass, reduced satellite cell proliferation, and slower rate of protein synthesis. Disruptions in skeletal muscle growth are associated with mitochondrial dysfunction, including reduced pyruvate flux into the mitochondrial matrix and lower complex I activity in the mitochondrial electron transport chain. This review summarizes current research on the mechanisms by which HS-induced placental insufficiency affects skeletal muscle growth in the fetus, with an emphasis on myogenesis, hypertrophy, protein synthesis, and energy metabolism. The evidence presented is primarily drawn from experiments using chronically catheterized fetal sheep exposed to maternal HS during mid-gestation. Additionally, we explore emerging nutritional strategies aimed at enhancing skeletal muscle growth in animals with FGR. These strategies hold promise not only for improving reproductive efficiency in livestock affected by prenatal stress but also for their translational relevance to human pregnancies complicated by placental insufficiency.

We report a lab experiment to study subjects’ preferences over their ordinal rank in an earnings distribution. Following an assignment of unequal earnings, subjects can select a monetary transfer from exactly one individual to another, not including themselves. This can potentially change their own position in the distribution, as well as influence overall inequality. The experiment varies whether the initial earnings assignment is random or is affected by preliminary competition. It also varies the reference group from a complete to a partial network. A majority of observed transfers reduce inequality by moving earnings from those with the highest rank to the lowest rank in the distribution. Rank-improving transfers are substantially more common for preliminary competition losers than winners. Transfers to individuals outside of the reference group are not uncommon, and they usually target as the source the individuals high in the income distribution. While generally weak overall, own rank preferences appear to be more common among men than women.

While virtually all academics who study human ‘race’ agree that it is a social construct, members of the general public still commonly regard ‘race’ as a biological property (i.e., they think that ‘races’ are genetically distinct). Even though empirical data from genetics and other fields do not support biological conceptions of race, this erroneous viewpoint is widely held, suggesting that there are impediments to effective communication of the relevant science. Here, we suggest five such impediments: (1) belief in genetic determinism, together with an over-reliance on an essentialist view of human groups, (2) overly simplistic interpretation of biological inheritance, (3) belief in the naturalistic fallacy and the associated naturalization of non-biological variation among racialized groups, (4) failure of the academic and educational communities to take responsibility for teaching the science of ‘race’ and racism, and (5) apologism towards racist founders of academic fields, including the evolutionary sciences. We address how and why each of these factors supports the spread of racism and suggest strategies for containing this spread.

We apply a synthesis review to revisit the concept, measurement, and operationalisation of social inclusion and exclusion in the context of comparative social policy, integrating the vast literature on the concepts, with the aim of elucidating a clearer understanding of the concepts for use by scholars and policymakers around the planet. In turn, we outline the conceptual development of the concepts, how they have been operationalised through social policy, and how they have been measured at the national and individual levels. Through our review, we identify limitations in extant conceptualisation and measurement approaches and suggest directions for refining conceptual and measurement frameworks to enhance their utility in social inclusion policy, emphasising the concepts’ multidimensional, multilevel, dynamic, and relational essence and highlighting their connection to related concepts such as social capital, social integration, and social citizenship.

This study estimates productivity losses resulting from intellectual decrement due to paediatric lead exposure in low- and middle-income countries (LMICs). The published literature on blood lead levels in LMICs was reviewed and summarised. Intelligence Quotient decrement and consequent productivity losses were calculated for a one-year cohort of 5-year-old children in each country. We calculated the present value of lifetime earnings as the discounted average earning potential for workers in a specific economy. Blood lead level (BLL) data for children were available for 39 countries and could be interpolated for additional 82 countries, resulting in 121 countries in the final analysis. Total lead-attributable productivity losses in LMICs ranged from USD 305 billion in our high discount scenario to USD 499 billion in our low discount scenario for each one-year cohort of 5-year-old children (2019 USD). As a share of GDP, these costs ranged from 0.7 to 4.2% by region, depending on discount scenario used. Total economic impacts were generally consistent with previous estimates and further validate those efforts with a substantially expanded dataset. Differences in the findings resulted primarily from the use of a more conservative dose–response model in the present study. Improved reporting of BLLs is essential and could be facilitated through a centralised registry of study results.

We evaluated the impact of recent revisions to the Clinical and Laboratory Standards Institute (CLSI) aminoglycoside breakpoints on susceptibility within Enterobacterales and Pseudomonas aeruginosa at a Canadian academic hospital. While the aminoglycoside breakpoint changes minimally affected overall susceptibility, the impact of these changes was notable within beta-lactamase producing Enterobacterales.

This article examines professional diviners employed by the Qing (1636–1912) government to assist in local administration. Known as yin-yang officers, these officials served among the technical and religious specialists embedded in prefectural and county governments across the empire. Although they held marginal or unranked positions within the formal bureaucracy, yin-yang officers played a vital role in both administrative and ritual life at the grassroots level. By tracing their training, sources of authority, and everyday responsibilities, this article sheds light on the Qing’s local technical and religious bureaucracy—an often-overlooked dimension of imperial statecraft that bridged ritual, cosmological knowledge, healing and divination, and official governance. It argues for the importance of examining imperial bureaucracy from below, showing how these unsalaried, low-level figures helped sustain the empire’s overstretched administrative apparatus well into the early twentieth century.
