The aim of this study was to investigate the prevalence of anemia in twin pregnancies and the influence of anemia on maternal and neonatal outcomes. This retrospective study included twin pregnant women who delivered in a tertiary hospital in China from January 2018 to December 2018. Patients were divided by WHO criteria (hemoglobin <11.0 g/dL): the anemic and nonanemic groups. Patients with anemia were further classified as recovered or unrecovered subgroup after oral iron therapy. Maternal and neonatal outcomes in women carrying twins were compared using Student’s t test and the chi-squared test or the Fisher exact test. Univariable and multivariable logistic regression models were used to determine the association of maternal and neonatal characteristics with anemia. Linear regression analysis was used to estimate mean birth weight and gestational week. The prevalence of anemia was 42.6% (182/427) in twin pregnancies. The anemic group had higher rates of low 1-minute Apgar score (4.4% vs. 1.8%, p = .028), perinatal death (1.9% vs. 0.2%, p = .012) and neonatal intensive care unit (NICU) admission (27.2% vs. 20.2%, p = .017; adjusted OR, 1.478; 95% CI [1.07, 2.044]). The recovered subgroup had lower NICU admission rate (13.5% vs. 30.3%, p = .006; OR, 0.388; 95% CI [0.186, 0.809]), higher gestational week and birth weight (β, 0.954 week; 95% CI [0.114, 1.794] and β, 171.01 g; 95% CI [9.894, 332.126] respectively). The prevalence of anemia in twin gestation is high. Anemia is associated with adverse neonatal outcomes, and correction of anemia significantly improved the pregnancy outcomes.

Following the vote in favour of birth control at the 1930 Lambeth Conference, the Church of England became the first major Christian denomination explicitly to condone the use of birth control. This paper argues that the bishop of Winchester, Theodore Woods, was the previously unheralded principal actor responsible for reversing the position of the Church. Woods was convinced that the Church needed to ‘modernise’ its position in order to secure a receptive audience for its higher-ordered teachings on marriage, sex and especially procreation. In turn, he hoped to bring about an increased birthrate amongst the eugenically ‘desirable’ English middle and upper classes.

In the early 1900s, Washington, D.C. contained many alleys in the interior of blocks inhabited by impoverished Black residents. Elite reformers engaged in an aggressive campaign to eliminate alleys, on the grounds of their purported unsanitary environment and high disease prevalence. In this paper, I combine quantitative, qualitative, and spatial sources to explore new perspectives on segregation, public health, and the racialized efforts of housing reformers during this period. I find that reformers overstated the horrors of conditions in alleys and their effects on residents’ health: poorer health among alley residents was in large part due to Black residents’ marginalization wherever they might live. Alleys’ status as racialized space, coupled with progressive paternalistic racism, facilitated the discursive construction of alleys as pathological “breeding grounds of disease.” Further, my findings shed new light on micro-configurations of segregation within racially mixed neighborhoods, as well as the social experience and meaning of such configurations. Far from indicating harmonious coexistence, the proximity of such alleys to white homes and institutions spurred elite Washingtonians’ self-interested fear of disease spreading beyond the alleys. Thus, this pattern of segregation helps explain the zeal of the campaign to eradicate alleys: as a means of achieving separation from undesired Black neighbors whom white reformers associated with contagion.

In 2016, British investigative journalist Simon Rogers created a map/timeline of Twitter hashtags associated with Black Lives Matter. The map (which no longer exists) indirectly shows both the intensity of Black Lives Matter protests and their geographic scope. Within the United States, we see not only protest activity in metropolitan areas with large black population percentages, but also protest activity in metropolitan areas with few (if any) African Americans. Further, we see protests not just in the United States but throughout the world. The 2020 George Floyd murder arguably spurred more protests against police violence within the United States and around the world than any other moment. We understand these protests as part of a broader decolonial project that seeks to eradicate racialised violence. How does this project develop? In examining Black Lives Matter as a movement, most have either focused on domestic activity within the United States or on instances of international activity, but few have attempted to theorise its spread. I suggest that any approach that focuses solely or primarily on technological advances or on the work of activists misses an essential and under-examined element – US Black popular culture.

By reconstructing the lending policy of the European Investment Bank (EIB) from its inception in 1958 to the late 1970s, this article shows that, until the 1970s, the EIB did not pursue EEC (European Economic Community) policies but policy elaborated at the national level. The individual member states’ political priorities and preferences played a key role in shaping the loan operations and the bank's loans were used rather more individualistically by each community country in pursuit of national aims. This situation started to change in the 1970s when internal and external developments to the EEC redeployed and refocused the methods and objectives of the bank so that lending progressively became the result of the interplay between EEC institutions. Gradually, the EIB moved away from being a mere member state's tool to pursue individual national policies, transformed into an EEC policy-driven bank and it became the financial arm of the EEC.

We study $L^p$-Sobolev regularity estimates for the restricted X-ray transforms generated by nondegenerate curves. Making use of the inductive strategy in the recent work by the authors, we establish the sharp $L^p$-regularity estimates for the restricted X-ray transforms in $\mathbb {R}^{d+1}$, $d\ge 3$. This extends the result due to Pramanik and Seeger in $\mathbb {R}^3$.

Between 1895 and 1916, a Conference on International Arbitration met annually at Lake Mohonk, New York, seeking to implement arbitration as a substitute for war. This article considers the aims, effects, and limitations of these conferences, including the problematic assumptions underpinning their apparent progressivism. The belief that an enlightened public opinion would play a decisive role in advancing arbitration will be interrogated, as will the conviction that the Mohonk group provided a mouthpiece for an emergent “international mind.” The article shows how these conferences evoked a “global” public opinion that was simultaneously (and paradoxically) expansive, exclusionary, forcible, and manipulable. It reveals too how American conceptions of internationalism took shape, anticipating aspects of Wilsonianism.

This article examines the state's actions to arm and disarm the civilian population in Spain during the convulsive final years of the Bourbon Restoration period (1917–23). While this topic has received little attention in the abundant literature on the crisis of the liberal regime in Spain, it is crucial to fully understanding the inherent causes and nature of the high levels of political violence which characterised this period. By analysing the ‘selective rearmament’ of part of the population by both legal and illegal means, this article considers the relationship between dynamics of civilian disarmament and rearmament and the evolution of the alleged state monopoly on violence in Spain.

US regulations mandate annual N95 mask fit testing for healthcare workers, but the optimal testing interval is unknown. In our study using data from 12,565 healthcare workers, the probability of survival free from fit-test failure after 3 years was 99.4%, suggesting that less frequent fit testing every 3 years would be safe.

Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical diversity such as Root TTR (Guiraud’s index) and D (vocd-D and HD-D) that have been preliminarily shown to lack reliability in spoken L2 contexts and/or have been consistently shown to lack reliability in written L2 contexts. In this study, we empirically evaluate lexical diversity indices with respect to two aspects of reliability (text-length independence and across-task stability) and one aspect of validity (relationship with proficiency scores). The results indicated that neither Root TTR nor D is reliable across different text lengths. However, support for the reliability and validity of optimized versions of MATTR and MTLD was found.
