Following the opening of the Suez Canal in 1869, long-distance pilgrimage to Islamic holy sites expanded and quickened, resulting in the spread of cholera among travelers. The necessity of taking circuitous routes to holy cities both inside and outside Iran significantly exacerbated the spread of cholera. Although potential factors such as inadequate public health infrastructure and ineffective quarantine measures contributed to the dissemination of cholera, overall religious mobility in the form of pilgrimage primarily factored behind cholera's spread. Analyzing the influence of religious mobility and rituals sheds light on how pilgrims, as contagions, dealt with the pandemic and the treatment they received from authorities, members of host societies, and individuals within and outside Iran during the cholera pandemics of the1890s and early 1900s.

The global pandemic exposed many flaws in the gendered political economy. It also illuminated how essential care is to our economy and to our flourishing. Yet, when care is dependent on a capitalist system that relies on competition, there will always be people who receive care and those that will not. In such a system, care is wrongly perceived to be a “choice” one can opt into or out of. This short essay grapples with the discourse of care as a choice, particularly around reproductive decisions. Choices offered within a neoliberal market logic fail to understand the political relationalities of such choices. Drawing on my personal experience of an abortion and other examples from the first year of COVID-19, this essay demonstrates how little choice there is in matters of care; care connects and disconnects one another regardless of personal choices. If matters of care persist in the realm of the market reliant on rational economic autonomous actors, then the many interrelationalities of care that the pandemic exposed will not have any impact on attaining a more caring society. This is particularly important given the nature of abortion politics in the United States. I argue that abortion is health care, and is often the most caring decision a pregnant person can make for the world they are trying to maintain, continue, and repair (per Tronto 1993). Care is not a choice; it is fundamental to human society.

By far the greatest number of photographs of Nazi sites of violence were taken by the perpetrators. Some Jews did work as official photographers in the ghettoes, but during deportations, in the camps and extermination centers, and at the sites of mass shootings, only Gestapo officers, SS men and women, or other authorized personnel were officially permitted to use cameras. In the Mauthausen concentration camp, for example, as Lukas Meissel explains in his contribution to the excellent collection of essays, Fotografien aus den Lagern des NS-Regimes. Beweissicherung und ästhethische Praxis, “only members of the so-called Erkennungsdienst (identification department) were allowed to take photographs.”1 These photographs “do not reflect the reality of the camp” (45). They seldom confront us directly with Nazi violence. Instead, these pictures offer (false) images of frictionless operations, visual testimony to the efficiency of the perpetrators, usually meant to impress their superiors.

We propose that while positive performance feedback is positively related to firm sentiment, negative performance feedback is negatively associated with the firm sentiment. Additionally, overconfident Chief Executive Officers (CEOs) will improve the positive relationship between positive performance feedback and firm sentiment and reduce the negative relationship between negative performance feedback and firm sentiment. Using 7,182 firm-year observations for the 2004−2017 period, we show that positive performance feedback positively affects firm sentiment, and negative performance feedback negatively influences firm sentiment. We also found that higher levels of CEO overconfidence will minimize the negative impact of negative performance feedback on firm sentiment. Our research extends the current discourse on organizational impression management (proxied by firm sentiment) and CEO overconfidence research as we provide a nuanced relationship between firm performance feedback and organizational impression management. Our findings have theoretical and practical implications for corporate governance leaders and shareholders.

Digital educational game-based apps can be effective in helping young children develop language skills, particularly when paired with formal instruction. However, we need to know more about how educational games benefit learning in the absence of formal instruction, given children’s proficiency with and willingness to use mobile devices anytime, anywhere. This study uses a randomized controlled trial design to investigate the impact of a digital app—ABCmouse English—on L2 learning of seven- and eight-year-old Japanese children over a 16-week period. Pre- and post-assessments of the children’s English proficiency, together with an analysis of when and how they played with the app, were used to shed light on the relationship between the children’s in-app game choices and their language learning outcomes. Surveys and interviews with parents provide qualitative insights and information about the experiences of children and their families while using the app and its impact on their development as language learners.

In this paper, we investigate the attitude manoeuver planning and tracking control of the flexible satellite equipped with a coilable mast. Due to its flexible beamlike structure, the coilable mast experiences bending and torsional modal vibrations in multi-direction. The complex nonlinear coupling and other external disturbances significantly impact the achievement of high-precision attitude control. To overcome these challenges, a robust attitude tracking controller is proposed for easy implementation by the Attitude Determination and Control System (ADCS). The controller consists of a disturbance compensator, feedforward controller and output feedback controller. The compensator, based on a Nonlinear Disturbance Observer (NDO), effectively compensates for the cluster disturbances caused by vibrations, environmental factors and parameter perturbations. The feedforward controller tracks the desired path in the nominal satellite model. Furthermore, the output feedback controller enables large-angle manoeuver control of the satellite and evaluates the suppression effect of the controlled output on the observation error of cluster disturbances used the ${L_2}$-gain. Simulation results demonstrate that the proposed controller successfully achieves high-precision attitude tracking control during large-angle manoeuvering.

This paper examines the impact of female education on fertility outcomes by using the Universal Primary Education (UPE) program in Malawi as a natural experiment. The finding indicates that the UPE policy improves rural women's educational attainment by 0.42 years and an additional year of female education decreases women's number of children ever born and the number of living children by 0.39 and 0.34, respectively. An analysis of potential mechanisms suggests that the decreased fertility rates are likely driven by the reduction in women's fertility preferences, the postponement of marriage, and the delay of motherhood. Contrarily, the study finds no evidence that increased female education affects women's labor force participation and the use of modern contraception.

Following the most dramatic migration episode of the 21st century, Turkey hosted the largest number of Syrian refugees in the world. This paper assesses the impact of the arrival of Syrian refugees on the Turkish children's health, with a focus on height – a standard nutritional outcome. Accounting for the endogenous choice of immigrant location, our results show that Turkish children residing in provinces with a large share of refugees exhibit a significant improvement in their height as compared to those living in provinces with fewer refugees. Against other potential channels, a refugee-induced increase in maternal unemployment and the associated increase in maternal care seem to explain the observed positive effect on children's health.

The crystal structure of nicarbazin has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Nicarbazin is a co-crystal of 4,4′-dinitrocarbanilide (DNC) and 2-hydroxy-4,6-dimethylpyrimidine (HDP) molecules. Nicarbazin crystallizes in space group P-1 (#2) with a = 6.90659(8), b = 12.0794(4), c = 13.5040(7) Å, α = 115.5709(11), β = 102.3658(6), γ = 91.9270(4)°, V = 982.466(5) Å3, and Z = 2. The DNC and HDP molecules are linked by two strong N–H⋯O and N–H⋯N hydrogen bonds, and the HDP molecules are linked into centrosymmetric dimers by another N–H⋯O hydrogen bond. These strong hydrogen bonds link the molecules into layers parallel to the ab-plane and parallel stacking of both DNC and HDP molecules is prominent in the structure. The powder pattern has been submitted to ICDD for inclusion in the Powder Diffraction File™ (PDF®).

Debates about cultural participation of persons with disabilities within legal and socio-legal scholarship and within disability studies tend to remain disconnected. This article brings legal analysis and other academic disciplines into a critical dialogue. It sheds light on how the right to cultural participation is understood from the bottom up, building on a study carried out across Europe. Participants in this study perceived opportunities to participate in, and to contribute to, arts and culture in ways that are consistent with the human rights approach to disability as expressed in the UN Convention on the Rights of Persons with Disabilities, and as central to the concept of inclusive equality. Cultural participation was also understood as intrinsic to the humanity of all people, as vital to inclusion in mainstream life, as capable of communicating experiences or identities not otherwise represented, and as potentially transformative of art-forms and ultimately, of society.

Intertidal macrobenthos at the small Chernaya Bight (the White Sea) was surveyed six times during 1993–2018 in order to study spatiotemporal variability. Distributions of sediments and macrophytes were highly variable in both space and time, as were most macrofaunal community attributes. Biomass slightly increased with time, while no long-term trends were found in total abundance, diversity, or functional structure. All community attributes were patchily distributed across the beach, and their patterns were not spatially autocorrelated and poorly associated with sediment properties, but changed considerably from year to year. Temporal changes in the community composition were considerable but less substantial compared with the spatial variations. The overall dynamics of species structure did not show any regular trend-like pattern but formed quasicyclic trajectories in ordination space, with nondirectional, spatially noncorrelated fluctuations around some relatively stable state. Comparison with two other neighbouring intertidal sites, studied annually in 1987–2017, showed that macrofauna at every site had similar average biomasses and common dominant species; however, the communities maintained their specificity in structure and exhibited distinct types of dynamics. In particular, the communities demonstrated different long-term trends in total biomass and diversity and followed their own paths in dynamics, appearing as differently oriented interannual trajectories. Nine most abundant species revealed no significant among-site correlations in abundance, and only two bivalve species showed good intersite agreement in dynamics of biomass. We suggest that local benthic communities are largely influenced by site-specific environmental conditions, resulting in independent and even opposite patterns of dynamics in neighbouring localities.

This article studies the impact caused by the success and dissemination of Broussais’ theories on the use of leeches as a medical supply on Spanish–French trade relations, as well as its consequences for the Spanish market between 1821 and the 1860s. Analysing the documents produced by the different public administrations, together with newspaper and archival sources in both Spain and France and the literature and legislation of that period, allows us to understand the evolution of this trade and the heavy impact it had on the autochthonous population of this animal resource. The article reveals how, at the beginning of the 1820s, leeches became an important medical supply and how the demand for them increased significantly. This gave rise to a trade relation between Spain and France that led to the overexploitation of the resource, the issuing of regulations on the matter, and the search for technological solutions to increase the production of leeches.

This case addressed irregularities in the investigation of the death of Digna Ochoa y Plácido on October 19, 2001. The petition alleged that her death occurred in the context of harassment and attacks against human rights defenders in Mexico. The Inter-American Commission of Human Rights (the Commission) found that the state was responsible for violations of rights related to judicial protection and judicial guarantees under Articles 8(1) and 25 and personal integrity under Article 5 of the American Convention on Human Rights (ACHR).
